Abstract
Description
Technical Field
[0001] This utility model belongs to the field of orthopedic instrument technology, specifically relating to a Kirschner wire angle positioning sleeve. Background Technology
[0002] In orthopedic surgery, Kirschner wires are an important internal fixation device, widely used in fracture reduction and fixation, joint fusion, osteotomy and correction, and spinal surgery. Their unique design allows surgeons to quickly and accurately insert them into the bone during surgery, achieving effective fixation and support. However, with the continuous advancement of modern orthopedic surgical techniques and the increasing complexity of surgeries, the traditional use of Kirschner wires has gradually revealed some limitations.
[0003] Traditional Kirschner wire manipulation relies heavily on the surgeon's experience and feel, lacking precise guidance and positioning devices. In complex fractures or surgeries requiring precise positioning, surgeons often struggle to accurately insert the Kirschner wire into the intended location by feel alone. This not only increases the difficulty and time cost of the surgery but may also affect the surgical outcome. Utility Model Content
[0004] To address the aforementioned technical issues, this invention presents a Kirschner wire angle positioning sleeve, which aims to adjust the angle and parallel position of the Kirschner wire at the same insertion point through multiple holes and angle adjustment functions, thereby meeting diverse clinical needs.
[0005] To achieve the above-mentioned technical objectives, this utility model is implemented through the following technical solution: a Kirschner wire angle positioning sleeve, comprising a sleeve body, the sleeve body being frustoconical in shape, with a central positioning hole penetrating through its middle portion, a plurality of inclined guide holes being arranged around the central positioning hole, and a plurality of fixing adjustment holes being arranged around the central positioning hole, the fixing adjustment holes being located between the central positioning hole and the inclined guide holes, and the diameter of the fixing adjustment holes being smaller than the diameters of the inclined guide holes and the central positioning hole.
[0006] Preferably, the axis of the inclined guide hole forms a 10° angle with the axis of the central positioning hole.
[0007] Preferably, the bottom surface of the sleeve body is configured as a serrated surface.
[0008] Preferably, a holding handle is also fixedly connected to the upper outer wall of the sleeve body.
[0009] The beneficial effects of this utility model are:
[0010] Compared with the prior art, the positioning sleeve of this utility model first inserts the Kirschner wire vertically into the bone cortex through the central positioning hole when inserting the Kirschner wire. Then, the angle of the Kirschner wire is adjusted through the inclined guide hole as needed, and then the Kirschner wire is inserted through the fixing adjustment hole to fix the position or adjust the parallel position. This realizes the adjustment of the angle and parallel position of the Kirschner wire at the same insertion point, which meets clinical needs. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example 1
[0020] To achieve angle and parallel position adjustment of Kirschner wires at the same insertion point and meet diverse clinical needs, this embodiment proposes a Kirschner wire angle positioning sleeve, see reference. Figures 1 to 4As shown, the device includes a sleeve body 1, which is a frustum-shaped sleeve made of medical-grade stainless steel with a height of 20mm. A central positioning hole 2, 2.5mm in diameter, is formed through the middle of the sleeve. Multiple inclined guide holes 3, also 2.5mm in diameter, are arranged around the central positioning hole 2, forming a 10° angle with the axis of the central positioning hole 2. Multiple fixing and adjusting holes 4, 2mm in diameter, are also arranged around the central positioning hole 2, located between the central positioning hole 2 and the inclined guide holes 3.
[0021] When inserting a Kirschner wire, the Kirschner wire is first inserted vertically into the bone cortex through the central positioning hole 2. Then, the angle of the Kirschner wire is adjusted through the tilt guide hole 3 as needed. Finally, the Kirschner wire is inserted through the fixing adjustment hole 4 to fix its position or adjust its parallel position. This allows for the adjustment of the angle and parallel position of the Kirschner wire at the same insertion point, meeting clinical needs.
[0022] To improve the stability of the sleeve body 1 during the insertion of Kirschner wires, the bottom surface of the sleeve body 1 is set as a serrated surface 5 to enhance the bone surface gripping force and prevent slippage during the operation.
[0023] Meanwhile, in order to facilitate holding the sleeve body 1, a holding handle 6 is also fixedly connected to the upper outer wall of the sleeve body 1.
[0024] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
