Technical Field

The invention relates to a multifunctional traction and bone-knitting fixing device for medical operation, which is mainly used for a new traction and fixation minimally invasive treatment technology of limb fracture or comminuted fracture of a human body.

Background

At present, in the medical field, there are various treatment methods for human limb fracture, and traditional Chinese medicine conservation treatment: 1. external fixation with gypsum; 2. externally fixing the treatment method by using a splint; these treatments can only be used on minor injuries to the fracture of the bone and cannot accurately locate the fracture that is completely displaced; western medicine: has the tradition and pulls the treatment, will pull the nail and drive into the human body and pierce through the bone, the advantage: the scar is small; the disadvantages are as follows: 1. the traditional traction nail is designed into one piece, and the traditional traction nail needs to penetrate through bones to vibrate greatly when being driven into a human body, so that secondary damage is caused by the thorough displacement of cracked bones; 2. the traditional traction nail can only be driven into a single bone after penetrating through a human body, but the lower limbs of the human body are not suitable for double bones, so that a doctor selectively drives the traction nail into a calcaneus, and the traction effect cannot be ensured because the calcaneus and the double bones of the shank are not on the same vertical line, so that western medicine in hospitals at present can select steel plate internal fixation for operation; the steel plate is used for fixing the surface to be seen again, and the surface is not scientifically damaged but is greatly damaged after analysis, 1, people who have an operation talk about tiger color change to cause psychological fear, 2, waist anesthesia is not well received, part of people leave extravasated blood due to injury of waist joints caused by improper anesthesia, and sequela is left due to long-term waist swelling pain caused by unsmooth blood; 3. the operation is fixed by a steel plate, the modeling angle of the steel plate is not completely matched with the natural curve of the bone of a human body, in addition, under the condition that the blood is fuzzy, three parties cannot see that the bone-knitting sight line is poor when the operation is carried out in a small opening of one party, the abnormal contraposition after the operation often fails to meet the requirement of anatomical contraposition, the growth of the bone is influenced, secondary operations are caused, bone grafting (upper and lower supplement) and other phenomena are caused, and even the life disability and other events of a patient are caused by serious contraposition inaccuracy errors; 4. even if the operation is smooth for one year, the secondary injury caused by the operation of internal fixation is required, the internal fixation is always carried out because the incision is fuzzy, and the position of a fixed object is not easy to find, so that the injury of the operation knife wound to the human body is increased.

Referring to fig. 4, showing patent a, the first embodiment of the invention is a method for using the multifunctional distraction bone fixation device for distraction bone fixation: 1) the patient is laid on a sickbed, 2) no operation is performed, (after detumescence) firstly the multifunctional traction fixing device is mastered according to the displacement condition of X-ray film fracture and the width and the length of legs, the position of the traction nail 2 and the position of a second mounting hole 1-2 at the middle section of the traction splint 1 are determined, 2) disinfection is firstly performed, 3) local anesthetic is injected, 4) a doctor can drive two traction nails 2 into the bone by penetrating the cortex in turn for about 10 mm, if a special tool is available, the bone is pressed in turn, 5) then a reinforcing nut 5 is arranged on the screw thread 2-1 of the traction nail 2 and the position is determined, 6) the fixing device is loosened, the traction splint mounting hole 1-1 is selected to be sleeved on the screw thread 2-1 of the traction nail 2, and the other side is also arranged, and meanwhile, a reinforcing nut 5 is arranged on screw threads 2-1 of the traction nails 2 at two sides, and is screwed and fixed inside and outside the traction splints 1, 7) a nail protecting screw 4B is arranged in a screw hole 1-4 at the top of the traction splint 1, and is screwed and propped against the traction nail 2 to protect the angle action of the traction nail 2, and finally, the thigh of a patient is protected on a traction frame, and a traction weight is hung on a traction handle screw 3 to pull and drag.

As shown in fig. 5, fig. 6, fig. 7 and fig. 8, in this version (B, C, D, H), the use method of the multi-functional distraction bone fixation device of the second embodiment for distraction bone fixation and auxiliary fixation: 1) the patient is arranged on a sickbed, the thigh of the patient is protected to the traction frame II, and a doctor installs a traction bone-knitting fixing device and an auxiliary fixing needle seat in advance, adjusts the angle and installs a traction nail 2 according to the displacement condition of the patient X-ray film fracture; 2) when in fixation, one side of the traction splint 1 is loosened, the traction device is placed at the traction position of the leg, the traction nails 2 at the front ends of the two sides are driven into the bone in opposite directions in sequence (if special tools are used, the bone is preferably pressed into the traction nails in opposite directions at the same time), and after the traction nails 2 are checked to be properly driven into the bone, all the reinforcing nuts 5 are screwed down at the same time; 3) installing a screw protection screw 4B in a screw hole 1-4 at the top of the traction clamping plate 1, screwing the screw protection screw to abut against the traction screw 2 to protect the angle of the traction screw, and finally hanging a traction weight on a traction handle screw 3 for traction; 4) after the traction procedure is finished, auxiliary fixing is installed, 1) firstly, the needle head of the auxiliary fixing needle 6 is sleeved into the needle penetrating hole, and a reinforcing nut 5 (a spring, a flat pad and the nut 5 can be pressed at first) is installed on the screw thread 6-1 of the auxiliary fixing needle 6 from the needle head direction; 2) the needle head of the auxiliary fixing needle 6 is driven into a fixing target to penetrate through the cortex to prop against the displaced bone, a reinforcing nut 5 is arranged outside the needle penetrating hole on the screw thread 6-1 at the rear end of the auxiliary fixing needle, and then the reinforcing nuts 5 at the two sides of the auxiliary fixing piece are simultaneously screwed. Remarking: 1. if a spring (11) and a flat pad (12) are arranged, the reinforcing nut 5 at the rear end of the fixing needle 6 is loosened, and the reinforcing nut 5 below the spring is tightened to properly increase the compression of the spring; 2. the auxiliary fixing and mounting procedures comprise 7, 8, 9, 10. and the like, the same mounting procedure is not described, and the operation under X-ray is better if conditions exist; 3. if the leg swelling auxiliary fixing target is fuzzy, the patient is firstly drawn for several days, and the auxiliary fixing can be performed after the swelling subsidence every other day.
