Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a Kirschner wire guiding device for closed osteotomy surgery. Background Art
[0002] Osteotomy correction is a commonly used method for treating limb deformities and arthritis, especially around the knee joint. Incomplete osteotomy has the advantages of firm fixation, early movement, and rapid healing of broken ends. Incomplete osteotomy is divided into closed osteotomy and distraction osteotomy. In closed osteotomy surgery, not only the integrity of the osteotomy hinge needs to be considered, but also the thickness of the bone block obtained after osteotomy must be accurate. The two osteotomy planes after closure should fit as completely as possible. In closed osteotomy surgery, different medical staff can only insert the Kirschner wire into the osteotomy position based on experience and repeated attempts, that is, it can only be judged by the doctor's experience and naked eye observation. For doctors, it is technically difficult to insert multiple Kirschner wires into the same position. When it is impossible to insert the Kirschner wire to the target point at one time, multiple operations are required. Multiple punctures are relatively hidden dangers for patients, especially after the bone is broken, which will have an adverse effect on the operation. This will not only affect the effect of the operation, but also prolong the operation time. Utility Model Content

[0016] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0017] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
[0018] like Figure 1 and Figure 2 As shown, a specific embodiment of the utility model provides a Kirschner wire 500 guide device for closed osteotomy surgery, which is used for the Kirschner wire 500 puncture operation in osteotomy surgery to ensure that the insertion point of the Kirschner wire 500 remains the same, improve accuracy, and help reduce the risk of surgery-related complications; specifically includes an adjustment frame 100 and a positioning frame 200 that are hinged to each other, and the adjustment frame 100 can rotate on a vertical plane around the hinged end; the positioning frame 200 is provided with a positioning hole 210 at one end away from the adjustment frame 100, and a positioning needle 300 arranged along the plane of the positioning frame 100 is inserted into the positioning hole 210; the adjustment frame 100 is provided with a guide block 400 for sliding upward, and the outer side of the guide block 400 is provided with a plurality of pairs of guide holes 410 arranged in parallel up and down for inserting the Kirschner wire 500, and the front end of the Kirschner wire 500 inserted into the guide hole 410 can be against the outer peripheral surface of the front end of the positioning needle 300.
[0019] like Figure 1 and Figure 2As shown, through the above arrangement, the adjustment frame 100 and the positioning frame 200 of the guide device in this embodiment are assembled in a hinged manner, so that they can be easily clamped on the outside of the thigh surgical area when in use, and the positioning pin 300 is inserted into the positioning hole 210 at the end of the positioning frame 200. The positioning pin 300 is inserted into the correct position of the surgical area, and the rotation angle of the adjustment frame 100 and the relative position of the guide block 400 and the adjustment frame are controlled as needed. After the angle and position are adjusted, the positioning pin 300 is inserted into the guide hole 410. After the front end of the positioning pin 300 is punctured to the target position, each Kirschner wire 500 penetrates into the surgical area so that its front end is against the front end of the positioning pin 300, so that each Kirschner wire 500 can be accurately placed in the same position. When each Kirschner wire 500 is inserted and positioned to the same point, puncture errors can be avoided. The guide structure in the embodiment is used to ensure the accuracy of the Kirschner wire 500, which is conducive to achieving precise osteotomy, can effectively shorten the operation time, reduce the risk of operation-related complications, and achieve rapid recovery of patients.
[0020] As mentioned above, the positioning needle 300 of the guide device in this embodiment is used to puncture the target point, so that the front end of each Kirschner wire 500 can puncture the front end of the Kirschner wire 500. In order to improve the positioning accuracy, this embodiment is provided with a positioning tip 310 at the front end of the positioning needle 300. The front end of the Kirschner wire 500 passing through the guide hole can be against the outer periphery of the positioning tip 310. The provision of the positioning tip can improve the puncture accuracy and facilitate the operation of medical staff.
[0021] like Figure 1 and Figure 2 As shown, the guide device composed of the adjustment frame 100 and the positioning frame 200 is arranged outside the surgical area when in use. The adjustment frame 100 can rotate around the end of the positioning frame 200 as needed. In order to accurately control the rotation angle, in this embodiment, an angle plate 600 is provided at one end where the positioning frame 200 and the adjustment frame 100 are hinged, and an angle pointer 700 indicating the rotation angle of the adjustment frame is provided at one end where the adjustment frame 100 and the positioning frame 200 are hinged. In this way, the angle of the adjustment frame 100 can be accurately adjusted by the cooperation of the angle pointer 700 and the angle plate 600. In practical applications, the rotation adjustment range of the adjustment frame 100 is preferably 90°.
[0022] like Figure 1 and Figure 2As shown, in actual application, the adjustment frame 100 is arranged in a quarter arc structure. The guide block 400 can slide a quarter arc length. When the guide block 400 is located at any position, the Kirschner wire 500 passing through the guide hole 410 can be against the outer periphery of the front end of the positioning pin 500. In this embodiment, a slide groove is provided on the outside of the adjustment frame 100, and the guide block 400 is slidably installed in the slide groove. In this way, the guide block 400 slides stably through the cooperation between the slide groove and the guide block 400. In actual use, a tightening screw can be provided on the guide block 400 to fix the position of the guide block 400, thereby improving the convenience of adjustment; in addition, the guide block 400 needs to be able to be pulled out and disassembled from the slide groove to facilitate removal for cleaning or replacement.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
