Abstract
The utility model discloses an acromioclavicular joint fixation guider, which belongs to the technical field of medical instruments for the department of osteology and is used for accurate positioning and fixation guiding in a shoulder joint restoration and fixation surgery. The utility model adopts the technical scheme that: the acromioclavicular joint fixation guider consists of a positioning guide plate, a positioning pin and a guide pin, wherein the positioning guide plate is rectangular; positioning holes and guide holes are distributed on the plate surface of the positioning guide plate along a longitudinal axis of the plate surface; the positioning holes are divided into two groups which are positioned at the left and right ends of the plate surface respectively; the guide holes are divided into one group which is positioned between the two groups of positioning holes; and the number of the positioning holes and the guide holes in each group is 2 to 4. When the acromioclavicular joint fixation guider is used, the positioning pin is used for the accurate positioning according to the positions of the positioning holes, and then the guide pin guides a hollow bolt to fix an acromioclavicular joint, so the acromioclavicular joint fixation guider has the advantages of small wound and small damage to soft tissues, capability of reducing the influence of cervical plexus anesthesia on a patient because the duration of the surgery is short, and lightening medical burdens on the patient and the society because the recovery time for the postoperative patient is short and the postoperative patient is healed smoothly, simple and convenient technical operation, convenience for popularization in primary hospitals and the like.
Description
Technical field
This utility model relates to the fixedly guiding device that a kind of acromioclavicular joint operation is used, and belongs to the orthopedic medical device technical field.
Background technology
In orthopaedic medical treatment operation, the resetting and fixedly be a kind of operation that needs to be grasped of acromioclavicular joint dislocation.Acromioclavicular joint dislocation mostly is the direct violence damage, is subjected to directly clashing into causing injury as shoulder in vehicle accident.When this position fracture or dislocation, near ligament damage in various degree can causing causes the shoulder joint function obstacle.The operation method of treatment acromioclavicular joint dislocation is a lot, traditional has the Kirschner wire tension band to fix, hook plate is fixed, fixation with steel wire etc.In these methods, the shortcoming of Kirschner wire tension band fixing means is that Kirschner wire is deviate from easily, instability before and after fixing not firm causing; And the method for clavicle hook plate treatment acromioclavicular joint dislocation, though respond well, operation wound is big, soft tissue injury is heavy, and hook plate passes under acromion, produces under the acromion when the upper limb abduction easily and clashes into, and price is comparatively expensive, and be difficult for promoting at basic hospital.In view of this, medical worker that this is professional and patient wish to develop and develop new operating theater instruments and method, so that when the treatment acromioclavicular joint dislocation, reach better surgical effect, can reduce patient's misery and the burden that alleviates economically simultaneously, and can promote the use of at basic hospital.
The utility model content
Technical problem to be solved in the utility model provides that a kind of acromioclavicular joint resets and can quick and precisely locate, guide the fixedly acromioclavicular joint fixed guider of acromioclavicular joint of screw during fixing operation carrying out.
The technical scheme that solves the problems of the technologies described above is:
A kind of acromioclavicular joint fixed guider, it is made up of positioning guiding plate, positioning needle, guide pin, positioning guiding plate is a rectangle, plate face y direction is distributed with locating hole and pilot hole in plate face upper edge, locating hole is divided into two groups, lays respectively at the two ends, the left and right sides of plate face, and pilot hole is one group, between two groups of locating holes, the number of every group of locating hole and pilot hole is 2-4.
Above-mentioned acromioclavicular joint fixed guider, plank or macromolecular material making that described positioning guiding plate penetrates for not influencing lonizing radiation.
Above-mentioned acromioclavicular joint fixed guider, the pilot hole on the described positioning guiding plate are slotted eye.
Above-mentioned acromioclavicular joint fixed guider, the number of described every group of locating hole and pilot hole is 3.
Above-mentioned acromioclavicular joint fixed guider, the neck medicated cap that described positioning needle has the prevention positioning needle to continue to squeeze at the most advanced and sophisticated 1-1.5cm of distance place.
This utility model is accurately located according to position of positioning hole by positioning needle in use, guides fixedly acromioclavicular joint of hollow screw by guide pin again, and it is little to have wound, little to soft tissue injury; Operating time is short, can alleviate the influence of cervical plexus anesthesia to the patient; Patient's post-operative recovery time is short, and healing alleviates the medical burden of patient and society smoothly; Technical operation is easy, is convenient in advantages such as basic hospital popularizations.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a user mode sketch map of the present utility model.
Labelling is as follows among the figure: positioning guiding plate 1, positioning needle 2, guide pin 3, locating hole 4, pilot hole 5, acromion 6, clavicle 7, processus coracoideus 8
The specific embodiment
Fig. 1,2 shows that positioning guiding plate 1 of the present utility model is not by influencing plank or the macromolecular material making that lonizing radiation penetrate, and the length of plate face is 10-25cm, and width is 1-3.5cm, and thickness is 0.5-3cm, and the diameter of locating hole 4 is 2-4mm on the plate face.Positioning needle 2 and guide pin 3 are metal needle, and diameter is 2-4mm.
The using method of the present utility model that Fig. 3 shows is: after patient's cervical plexus is anaesthetized successfully, at first positioning guiding plate 1 is placed patient's shoulder, by the nail hole of perspective according to the definite locating hole 4 that should select in position of acromion 6 and processus coracoideus 8.Select to squeeze into first piece of positioning needle 2 to acromion 6 respectively at positioning guiding plate 1 near the nail hole in patient's shoulder outside behind the suitable nail hole, squeezing into the cortical bone of second piece of positioning needle 2 near the nail hole of patient's shoulder inboard to nearly 1/3 position, clavicle 7 China and foreign countries.The degree of depth of positioning needle 2 is not damaged important neurovascular structure and is advisable to pass the bilateral cortical bone.After the height of adjusting positioning guiding plate 1 makes pilot hole 5 inclined holes insert guide pin 3, can make guide pin 3 by acromioclavicular joint and point to acromion 6 directions, determine entry point under the X line monitors, the extended line that makes guide pin 3 is by acromion 6.Stationary positioned guide plate 1 is on the positioning needle 2 of both sides then.Afterwards, percutaneous passes acromion 6 by inclined hole through clavicle 7 far-ends with guide pin 3, and wherein guide pin 3 becomes the about 40-50 in angle ° with clavicle 7 outboard end axis; Go into the nail point apart from the about 2.5cm of acromioclavicular joint.X line perspective, acromioclavicular joint resets after the satisfaction.Little otch cuts skin successively, separates the through clavicle of subcutaneous tissue outside cortex.By being screwed into fixedly acromioclavicular joint of hollow screw behind the guide pin 3 storing packing rings.The perspective acromioclavicular joint resets fixing satisfied in the art.
