Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an auxiliary bone tunnel drilling positioning tool. Background Art

[0002] Orthopedics, also known as orthopedic surgery, is a specialty or discipline in medicine that specializes in the anatomy, physiology and pathology of the musculoskeletal system, using drugs, surgery and physical methods to maintain and develop the normal form and function of this system, as well as treat injuries and diseases of this system. With the changes of the times and society, the spectrum of orthopedic injuries has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and poliomyelitis have decreased significantly, while injuries caused by traffic accidents have increased significantly.

[0003] With the development and progress of science, orthopedics has made great progress in diagnosis and treatment, and medical methods have also made great progress. At present, the field of sports medicine often uses lumbar puncture needles to drill holes through the bone and fix them with traction wires. However, in practice, it is often impossible to quickly find the entrance to the bone tunnel after drilling through the bone, and multiple drillings are required, and there are no ready-made and convenient auxiliary tools. Utility Model Content

[0004] The utility model provides an auxiliary bone tunnel drilling positioning tool to solve the technical problem of being unable to quickly find the bone tunnel entrance after bone drilling and facing multiple drillings in practice.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The present application provides an auxiliary bone channel drilling positioning tool, which includes a sleeve and a handle. One end of the sleeve has a serrated structure to facilitate the engagement and fixation of the sleeve with the edge of the bone cortex, and the handle is arranged at the other end of the sleeve.

[0007] Furthermore, the sleeve is in a hollow cylindrical shape, and openings are arranged on the side wall of the sleeve from top to bottom.

[0008] Furthermore, the opening size is 1.8 mm.

[0009] Furthermore, the handle includes a handle and a knocking handle, and the handle and the knocking handle are respectively arranged on both sides of the sleeve opening.

[0010] Furthermore, the length of the handle is greater than the length of the striking handle.

[0011] Beneficial effects achieved by the utility model:

[0012] The auxiliary bone channel drilling positioning tool provided by the utility model is a special convenient auxiliary tool with the same purpose that is not seen on the current market. The utility model improves surgical efficiency, reduces surgical time, and reduces the risk of fracture and fixation failure caused by repeated drilling that cannot find the bone channel.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0019] The technical solution of the present utility model is described in detail below in conjunction with the specific drawings.

[0020] like Figure 1-Figure 2 As shown, an auxiliary bone channel drilling positioning tool includes a sleeve 1 and a handle 2. One end of the sleeve 1 has a serrated structure to facilitate the engagement and fixation of the sleeve 1 with the edge of the bone cortex, and the handle 2 is arranged at the other end of the sleeve 1.

[0021] In a specific embodiment, the sleeve 1 is in a hollow cylindrical shape, and openings are arranged on the side wall of the sleeve 1 from top to bottom.

[0022] In a specific embodiment, the opening size is 1.8 mm.

[0023] In a specific embodiment, the handle 2 includes a handle 21 and a knocking handle 22 , and the handle 21 and the knocking handle 22 are respectively arranged on both sides of the opening of the sleeve 1 .

[0024] In a specific embodiment, the length of the handle 21 is greater than the length of the striking handle 22 .

[0025] The following is a detailed description of the operation of the auxiliary bone tunnel drilling positioning tool:

[0026] First, estimate the drilling position, use an electric drill to drill the Kirschner wire into the predetermined position, insert sleeve 1 and tap moderately to make the serrations on the tip of sleeve 1 engage with the edge of the bone cortex and fix it, and then withdraw the Kirschner wire. After the lumbar puncture needle tube and the pre-set titanium-nickel lasso or ordinary suture enter the bone canal, withdraw the sleeve tool from the opening on the side wall to complete the rapid positioning of the bone canal.

[0027] The serial numbers of the embodiments of the present application are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
