Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

as shown in fig. 1 and 2, the auxiliary sinus healing device comprises a mounting ring 1 surrounding a drainage tube, wherein one side of the mounting ring 1, which is abutted against the skin, is a lower end surface, and a plurality of sliding grooves 11 are uniformly formed in the lower end surface of the mounting ring 1. One end of each runner 11 is directed toward the center position of the mounting ring 1, and the other end is extended toward the outer edge position of the mounting ring 1.

As shown in fig. 1 and 2, a sliding block 12 is slidably connected in each sliding groove 11, and the sliding block 12 is adhered and fixed on the skin. An extension spring 13 is arranged between one end of each sliding block 12, which deviates from the center of the mounting ring 1, and the inner wall of the sliding groove 11, a silica gel sleeve 14 is sleeved at the other end of each sliding block, and a driving mechanism 2 for driving the sliding blocks 12 to synchronously slide in the same direction is arranged on the mounting ring 1. Through setting up the frictional force between silica gel cover increase slider and the skin, also reduced the pressure of slider to skin simultaneously, avoid appearing allodynia or crushing wound.

When using the above device, the drainage tube is inserted through the mounting ring 1 and then inserted into the abdomen of the patient. Meanwhile, the sliding blocks 12 are bonded and fixed on the skin, and the sliding blocks 12 are distributed on the periphery of the wound, so that the device is fixed.

When the drainage tube is pulled out, the driving mechanism 2 is utilized to control the plurality of sliding blocks 12 to slide towards the central position of the mounting ring 1, meanwhile, the sliding blocks 12 drive skin around a wound to be gathered at the wound position, so that the wound is closed, the wound is pressed, and the compression hemostasis and healing principle is utilized to promote the healing speed of the wound and relieve the pain of a patient.

As shown in fig. 1 and 2, the driving mechanism 2 includes a driving ring 21 disposed on the upper end surface of the mounting ring 1, the driving ring 21 is rotatably connected to the mounting ring 1, and a locking mechanism 3 for fixing the driving ring 21 is disposed between the driving ring 21 and the mounting ring 1.

As shown in fig. 1 and 2, a plurality of driving rods 22 are vertically arranged at intervals on the lower end surface of the driving ring 21, and the plurality of driving rods 22 are located between the plurality of sliders 12. The upper end face of the mounting ring 1 is provided with a circle of sliding holes 15, and the sliding holes 15 are communicated with the sliding chute 11 and are used for the driving rod 22 to slide. Namely, the lower end surface of the driving rod 22 is slidably connected to the bottom wall of the slide hole 15.

As shown in fig. 1 and 2, the upper end surface of each slider 12 is obliquely provided with a connecting groove 16 penetrating through both side walls, one end of the connecting groove 16 communicates with the adjacent sliding hole 15, and the other end extends toward the outer edge position of the mounting ring 1, so that the driving rod 22 is slidably inserted.

When the control slider 12 brings the skin to converge at the wound site, the drive ring 21 is controlled to rotate, and the drive ring 21 brings the drive rod 22 to move synchronously, and the drive rod 22 slides along the sliding hole 15 into the connecting groove 16. With the continued rotation of the drive ring 21, the drive rod 22 will control the slider 12 to move towards the central position of the mounting ring 1 and gather the skin at the wound site, guided by the slanted attachment slots 16. Finally, the driving ring 21 is locked by the locking mechanism 3, so that the driving ring 21 and the slide block 12 are fixed to realize the stitching of the wound position.

As shown in fig. 2, the locking mechanism 3 includes locking plates 31 provided on both sides of the drive ring 21, each locking plate 31 being hinged to the drive ring 21. The locking plate 31 is provided with a locking rod 32 at one end facing away from the driving ring 21, the locking rod 32 is provided with a projection at one end facing away from the locking plate 31, and the mounting ring 1 is provided with a plurality of locking holes 33 at intervals for the locking rod 32 to be clamped and embedded.

When the locking mechanism 3 is locked, the locking plate 31 is pressed to drive the locking rod 32 to turn downwards until the locking rod 32 is clamped and embedded into the locking hole 33, and the locking of the locking mechanism 3 is realized. When the locking mechanism 3 is released, the control locking plate 31 drives the locking rod 32 to turn upwards until the locking rod 32 is completely separated from the locking hole 33, and the locking mechanism 3 is released.

As shown in fig. 2, two sides of the mounting ring 1 are hinged with a supporting rod 4, and the supporting rod 4 comprises a tube 41 hinged on the upper surface of the mounting ring 1 and a rod body 42 screwed on the tube 41. The ends of the pair of rod bodies 42, which face away from the mounting ring 1, are hinged with semicircular clamping plates 43, and rubber pads 44 are arranged on the inner walls of the clamping plates 43. The pair of clamping plates 43 are buckled with each other and used for wrapping and clamping the outer wall of the drainage tube, and meanwhile, a clamping hook 45 and a clamping ring 46 which are clamped and fixed with each other are arranged between the two ends of the pair of clamping plates 43.

Before the drainage tube is not pulled out, the rod body 42 is screwed and fixed on the tube body 41, then the whole support rod 4 is driven to drive the clamping plates 43 to turn over, so that the pair of clamping plates 43 clamps the drainage tube, and then the clamping plates 43 are fixed by utilizing the matching of the clamping hooks 45 and the clamping rings 46, thereby realizing the support and fixation of the drainage tube. At this time, the torsion force of the drainage tube and the wound position can be transferred to the position of the clamping plate 43, so that the wound is prevented from being torn or deteriorated, and the wound healing is promoted.

After the drainage tube is pulled out, the hook 45 and the snap ring 46 are released, the rod body 42 is unscrewed, and the rod body 42 and the clamping plate 43 are disassembled, so that the interference of the inoperative supporting rod 4 on the daily activities of patients is avoided, and the wound is ensured to be healed quickly.

Example two:

the difference from the first embodiment is that:

as shown in fig. 3-5, the driving ring 21 includes a plurality of independent air storage cavities 5, a plurality of driving rods 22 are located on the lower end surface of the driving ring 21 and respectively correspond to the plurality of air storage cavities 5 one by one, and each air storage cavity 5 is filled with air to form a pressurized environment higher than atmospheric pressure in the air storage cavity 5. A vent hole (not shown in the figure) which can be communicated with the air storage cavity 5 penetrates through one side of each driving rod 22, and a sealing ring (not shown in the figure) which can be in sealing fit with the sliding hole 15 is arranged at the opening of each driving rod 22 at the vent hole. Through the setting of sealing washer, when the lower terminal surface of actuating lever 22 and slide opening 15 cooperate, the high-pressure gas in the gas storage chamber 5 can not leak to guarantee the steady operation of device.

One of the sliding blocks 12 is provided with an air inlet 51 matched with the air passing hole at the bottom wall of the connecting groove 16, one end of the sliding block 12 close to the center of the mounting ring 1 penetrates through the silica gel sleeve 14 to form a same air outlet 52, an air passage 53 communicating the air inlet 51 with the air outlet 52 is arranged in the sliding block 12, one side of the silica gel sleeve 14 is integrally connected with an air pipe 54, one end of the air pipe 54 far away from the silica gel sleeve 14 is communicated with an implanter 55 with a hollow inner part, the air outlet 52 can be communicated with an inner cavity of the implanter 55 through the air pipe 54, the implanter 55 can be placed in a sinus of a human body, the implanter 55 is internally provided with an external recombinant human epidermal growth factor solution 56, the outer wall of the implanter 55 is provided with a plurality of micro-channels 57 communicated with the external recombinant human epidermal growth factor solution 56, and each micro-channel 57 has a continuously bent structure.

Further, the number of the air reservoir chambers 5 is preferably eight and the internal air pressures are equal.

When the drainage tube is used, the drainage tube is firstly pulled out, and the sinus is cleaned. Next, the implanter 55 containing the topical recombinant human epidermal growth factor solution 56 is placed in the cleaned sinus. Then the driving ring 21 is controlled to rotate, so that the driving ring 21 drives the driving rod 22 to move synchronously, and under the guiding action of the inclined connecting groove 16, the plurality of sliding blocks 12 can be controlled to move towards the central position of the mounting ring 1, and the skin is gathered at the wound position, so as to realize the occlusion of the sinus, and at the moment, the implanter 55 is placed in the sinus and cannot fall out.

Since the micro-channel 57 is used as the liquid outlet of the external recombinant hEGF solution 56, and a continuously bent zigzag structure is specially selected, the external recombinant hEGF solution 56 can not easily flow out by external vibration or inclination (such as turning over of a patient on a sickbed, and transition from a bedridden state to a sitting or standing state) without external pressure, so as to ensure the order and stability of the liquid medicine discharging process.

When the air pressure needs to be introduced into the implanter 55 to drive the external recombinant human epidermal growth factor solution 56 to be discharged into the sinus through the micro flow channel to promote the growth of the granulation tissue, the driving ring 21 is continuously rotated to move the driving rod 22 to the air inlet 51 of one of the connecting grooves 16 of the slide block 12, at this time, the high-pressure air in the air storage cavity 5 can be introduced into the implanter 55 through the air passage 53 and the air pipe 54 in the slide block 12, so that the air pressure inside the implanter 55 is higher than the external atmospheric pressure to drive the external recombinant human epidermal growth factor solution 56 to be discharged into the sinus through the micro flow channel to promote the growth of the granulation tissue.

Since a certain time is required for healing of the sinus, when the implant 55 is placed in the sinus, the healing of the sinus needs to be observed at intervals to timely remove the implant 55, thereby preventing the existence of the implant 55 from hindering the healing of the sinus. Thus, after the implanter 55 has been implanted for a period of time, the patient can continue to rotate the drive ring 21 in the same direction (it is emphasized that the drive ring 21 of the present application can only rotate in one direction). When the driving rod 22 is disengaged from the air inlet 51 of the sliding block 12, the driving rod 22 is only engaged with the sliding hole 15, the sliding blocks 12 are reset under the action of the extension spring 13, and the sinus ostium is opened so as to observe the healing condition inside the sinus. At the same time, the slider 12 is exposed to the outside atmosphere during the resetting process (since both sides of the connecting slot 16 are through the slider 12, i.e., the gas inlet 51 is communicated with the outside atmosphere through the connecting slot 16), and the gas in the implanter 55 reversely flows out and is finally exhausted to the atmosphere through the gas inlet 51. At this time, the external recombinant hEGF solution 56 in the implant 55 is not discharged into the sinus through the micro-channels 57.

It should be noted that: since a part of the gas originally remains in the slider 12 and the implanter 55 in the gas storage chamber 5 into which the gas is introduced into the implanter 55, the remaining part of the gas flows into the atmosphere after the slider 12 is returned, and the gas in the gas storage chamber 5 cannot supply effective gas pressure to the implanter 55 again to drive the liquid medicine to flow out (i.e., cannot be reused once). In order to prevent the patient or the medical staff from accidentally operating the driving ring 21 in the reverse direction, one side of the driving rod 22 is abutted against the sliding block 12 instead of the connecting groove 16, so as to achieve the function of stopping the back.

If the medical staff observes the healing condition in the sinus, the recombinant human epidermal growth factor solution 56 still needs to be applied to the granulation tissue in the sinus continuously to promote the healing of the sinus, and the driving ring 21 continues to rotate to repeat the above process, so as to realize that the adjacent gas storage cavity 5 introduces gas into the implant 55 and the liquid medicine is discharged into the sinus through the action of the gas pressure. The above process is repeated, and detailed description is omitted here. The application has eight air storage cavities 5 in total, and eight times of sinus opening and closing processes can be realized to the maximum extent.

The important points to explain are: the process of opening the sinus ostium at intervals can delay the epithelialization of the sinus ostium. The granulation tissue inside the sinus is given time to grow and finally the implant 55 is removed at the right time and the sinus is closed by means of several slides 12. The joint healing of the inner granulation tissue and the epithelial tissue of the sinus is realized.

Further, when the driving rod 22 is not engaged with the coupling groove 16, the air inlet 51 is located below the mounting ring 1 and shielded by the mounting ring 1, thereby preventing foreign materials and dust from contaminating the air passage 53. When the driving rod 22 is engaged with the connecting groove 16, the air inlet 51 is gradually moved toward the center of the mounting ring 1 until it is engaged with the air passing hole of the driving rod 22.

Further, when the locking rod 32 is inserted into the locking hole 33, the air passing hole of the driving rod 22 is matched with the air inlet 51 of the slider.

Furthermore, the interior of the implanter 55 is further provided with a boosting piston 58 capable of promoting the external recombinant human epidermal growth factor solution 56 to be discharged towards the micro-channel 57, and both sides of the boosting piston 58 are in sealing contact with the inner side wall of the implanter 55. And a driving spring 59 is arranged on one side of the boosting piston 58, which is far away from the external recombinant human epidermal growth factor solution 56, one end of the driving spring 59 is fixedly connected with the boosting piston 58, and the other end of the driving spring 59 is fixedly connected with the inner wall of the implanter 55.

Under the action of external air pressure, the driving spring 59 expands and contracts, and the boosting piston 58 moves towards the micro-channel 57 to press the external recombinant hEGF solution 56.

By providing the boost piston 58 to limit the position of the recombinant hmf solution 56, the recombinant hmf solution 56 is prevented from flowing back into the slider 12 through the air tube 54 when the patient changes posture (e.g., the patient turns over on the bed, changes from a lying state to a sitting or standing state). In addition, the boosting piston 58 can better press the external recombinant human epidermal growth factor solution 56 to the micro-channel 57 for discharging into the sinus.

Furthermore, eight inflation ports are formed in the upper end face of the gas storage ring body, the eight inflation ports are in one-to-one correspondence with the eight gas storage cavities 5 respectively, each inflation port is provided with a rubber plug 60, and the rubber plugs 60 can be matched with syringe needles.

The specific embodiments are only for explaining the present invention, and the present invention is not limited thereto, and those skilled in the art can make modifications without inventive contribution to the present embodiments as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
