Detailed Description

The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

Example (b): as shown in fig. 1, 2, 3, 4, 5, 6 and 7, the movable structure for ultrasonic scanning of the eye comprises a limiting bottom plate unit 1 which is arranged on the side surface of a scanner main machine a and is positioned below a fixed probe b, a sliding plate unit 2 which is arranged on the limiting bottom plate unit 1 and is used for adjusting the transverse position of the eye of a patient, a supporting membrane unit 3 which is used for supporting the chin of the patient, and two pulling column units 4 which are respectively arranged at the two ends of the sliding plate unit 2 and are used for adjusting the vertical height of the eye of the patient in a manner of adjusting the flattening amplitude of the supporting membrane unit 3.

In this embodiment, the fixed probe b is provided with an ultrasonic transmitter and an ultrasonic receiver inside according to the prior art, and the patient's eye is aligned with the fixed probe b for a period of time, so that the scanning result inside the eye can be displayed on the scanner host a.

The sliding plate unit 2 can slide on the limiting bottom plate unit 1, and the sliding damping is proper, so that the eyes of a patient can be vertically aligned with the fixed probe b, and the possibility of accidental deviation after alignment is relatively low, the two pulling column units 4 can be close to each other or far away from each other, and therefore the supporting membrane unit 3 is unfolded or folded, so that the eyes of the patient on the supporting membrane unit 3 can be finally aligned with the fixed probe b, and the pulling column units 4 have a position locking function, namely, the alignment action can be ensured to be continued for a period of time until scanning is finished.

The limit bottom plate unit 1 comprises a fixing plate 101 arranged on the side surface of the scanner main body a, a mounting groove 102 arranged on the upper surface of the fixing plate 101, and two fixing cylinders 103 which are arranged in the mounting groove 102 and are parallel to each other. The sliding plate unit 2 includes a rectangular plate 201, two circular hole channels 202 provided on the rectangular plate 201 and respectively used for inserting two fixing cylinders 103, a limit groove 203 provided on the upper surface of the rectangular plate 201 and used for inserting and mounting two pulling cylinder units 4, a support base plate 204 provided on the upper surface of the rectangular plate 201 and respectively located at both sides of the limit groove 203 and used for mounting the pulling cylinder units 4, and four elastic rings 205 respectively provided at both ends of the two circular hole channels 202 and used for clamping the fixing cylinders 103.

In this embodiment, the fixing cylinder 103 is a sliding track of the rectangular plate 201, and finally ensures that the eyes of the patient can be transversely and linearly adjusted in a sliding manner, the inner diameter of the elastic ring 205 is smaller than that of the circular hole 202, and the material of the elastic ring 205 is the existing rubber with medium elasticity, so that the final effect is that the rectangular plate 201 can slide on the fixing cylinder 103, and when the rectangular plate 201 slides to a desired position, the rectangular plate has sufficient friction fixing effect, that is, when the rectangular plate 201 slides, the chin rubs against the supporting membrane unit 3 to indirectly push, and when the rectangular plate 201 is pushed by hand assistance, the chin slightly shakes during alignment, and the rectangular plate 201 cannot slide again.

The pull column unit 4 includes an air cylinder 401 provided on the support base plate 204, a rectangular parallelepiped block 402 provided in the limiting groove 203, a push-pull plate 403 provided on an upper surface of the rectangular parallelepiped block 402 and connected to the air cylinder 401, and a threaded column 404 provided on the push-pull plate 403 and used for mounting the support membrane unit 3. The pulling column unit 4 further comprises a mounting hole 405 which is arranged on the push-pull plate 403 and used for inserting and mounting a cylinder shaft of the cylinder 401, two limit nuts 406 which are screwed on the cylinder shaft and are respectively positioned at two sides of the push-pull plate 403, a limit hole 407 which is arranged on the push-pull plate 403 and is positioned above the mounting hole 405, and a limit column part 408 which is arranged on the upper surface of the rectangular plate 201 and used for covering and protecting the cylinder 401 and limiting and fixing the push-pull plate 403.

The position-limiting column 408 includes a vertical plate 408a disposed on the upper surface of the rectangular plate 201 and located outside the cylinder 401, a lateral protection plate 408b disposed on the lateral surface of the vertical plate 408a and located above the cylinder 401, and a position-limiting rod 408c disposed on the lateral surface of the lateral protection plate 408b and inserted into the position-limiting hole 407. The pull stud unit 4 further includes a ball body 409 provided on the lower surface of the rectangular parallelepiped block 402 and configured to perform rolling friction on the inner bottom surface of the stopper groove 203.

In the present embodiment, the method of use and advantages of the pull column unit 4 are as follows.

Firstly, an air pump is connected to the outside of the air cylinder 401 initially to ensure that the push-pull plate 403 can effectively slide back and forth and is fixed after sliding, and the cuboid block 402 is engaged with the limiting groove 203, and the limiting hole 407 is engaged with the limiting rod 408c, so that the push-pull plate 403 has a stable linear sliding effect, and the problem of large offset is avoided.

Secondly, the threaded post 404 is the position for mounting the support membrane unit 3, which makes the support membrane unit 3 have an initial height adjustable effect, which means that the whole movable structure can be suitable for the specific situation of patients with long faces and short faces, and the limit nut 406 is the limit part for transmitting the displacement of the cylinder shaft to the push-pull plate 403, ensuring that the push-pull plate 403 can move along with the cylinder shaft.

Thirdly, the transverse area of the transverse protection plate 408b is larger than that of the cylinder 401, so that the cylinder 401 is not exposed, and the safety of the inner microstructure of the pulling column unit 4 is ensured.

Fourthly, the width of the rectangular parallelepiped block 402 corresponds to the width of the limiting groove 203, and the rectangular parallelepiped block 402 is completely vertically located in the limiting groove 203, so that the rectangular parallelepiped block 402 is not inclined, and finally, the rectangular parallelepiped block 402 is ensured to have relatively small moving resistance by the rolling friction effect at the ball body 409, and when the rectangular parallelepiped block 402 is moved to a proper position, the threaded post 404 and the support membrane unit 3, which are terminated when the air pump is not moved, can be kept still all the time.

The support membrane unit 3 includes four internally threaded tubes 301 provided on four threaded columns 404, respectively, a connection string 302 provided on the internally threaded tubes 301, and a chin support membrane 303 provided on the connection string 302. The support membrane unit 3 further comprises a lower bulge loop 304, an upper limit loop 305 arranged on the outer circumferential surface of the internally threaded tube 301, and a mounting loop 306 which is sleeved on the internally threaded tube 301 and is positioned between the lower bulge loop 304 and the upper limit loop 305 and is used for mounting the connecting rope 302. The support membrane unit 3 further includes a bump anti-slip membrane 307 provided on the chin support membrane 303.

In this embodiment, the chin support membrane 303 is made of a conventional low-elasticity nylon resin membrane, and the bump anti-slip membrane 307 is made of a conventional rubber membrane, so as to ensure sufficient support force and anti-slip resistance for the chin of the patient.

The internal thread tube 301 may be screwed to the thread post 404 in a rotating manner, so that the initial height of the chin support membrane 303 is adjustable, and finally the mounting ring 306 is sleeved to the internal thread tube 301, so that it is ensured that the connecting rope 302 is not twisted when the internal thread tube 301 rotates, and the whole chin support membrane 303 can be stably adjusted vertically and vertically, and certainly in this process, the four internal thread tubes 301 are preferably adjusted together, and the middle position of the chin support membrane 303 is ensured to be located at the lowest point, so that the chin of the patient is most stable after being placed on the chin.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the claims appended hereto.
