Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and specifically relates to a split-type bone file. Background Technology

[0002] Bone files are commonly used medical instruments in orthopedic surgery, generally used for shaping bones during surgical procedures. A common problem with existing bone files on the market is that the size and shape of a bone file are relatively fixed. The more frequently used cutting edges of the file typically wear down significantly, while the less frequently used edges wear down less. However, severe wear on even a small portion of the cutting edges can render the entire bone file unusable.

[0003] A similar "barrel effect" exists: a bone file needs to have cutting capabilities throughout, but partial wear leads to overall failure, which is extremely wasteful.

[0004] Therefore, there is an urgent need to design a new type of equipment to solve the above problems. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a split bone file, which is assembled by several split modules of bone file blocks. If any module is damaged, the damaged module can be replaced individually, which improves the flexibility of the bone file in use. At the same time, the setting of several connectors and interfaces enhances the connection strength and improves the efficiency of use.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a split-type bone file, including a first bone file block, a second bone file block, and a third bone file block. The second bone file block is located below the first bone file block and connected to it via a first connector. A first interface is provided at one end of the first bone file block near the second bone file block. A first mounting hole is provided within the first interface. The first connector extends from below the second bone file block and is threadedly connected to the first mounting hole. The third bone file block is located below the second bone file block and connected to it via a second connector. The modular design of the first, second, and third bone file blocks ensures partial replacement of the bone file, improving the efficiency of bone file usage. Simultaneously, the first interface between the first and second bone file blocks enhances their connection precision and rigidity, reducing the gap in connection during surgical procedures and improving surgical accuracy.

[0007] Furthermore, the second bone file block is provided with a first mounting groove; the first mounting groove is used for the installation of the first connector; one end of the first connector abuts in the first mounting groove, and the other end is threadedly connected to the first mounting hole. The threaded connection ensures that the second bone file block and the first bone file block can be smoothly locked together, improving the connection strength between the two.

[0008] Furthermore, the second bone file has a second interface at one end near the third bone file; the second interface has a second mounting hole. The second interface, in conjunction with the second mounting hole, provides space for the installation of the second connector, ensuring the stability of the connection.

[0009] Furthermore, the third bone file block is provided with a second mounting groove; the second mounting groove is used for mounting the second connector; one end of the second connector abuts against the lower end of the second bone file block and passes through the second mounting groove to be threadedly connected to the second mounting hole. The second mounting hole cooperates with the second connector to complete the connection between the second bone file block and the third bone file block, improving the connection strength; at the same time, the threaded connection facilitates the disassembly and replacement of each component.

[0010] Furthermore, both the first and second bone file blocks have cutting edges on their outer walls, and these cutting edges are coated with titanium nitride. The titanium nitride coating increases the surface hardness of the cutting edges.

[0011] Furthermore, the cutting edges are provided with a groove bottom arc. The design of the cutting edges combined with the groove bottom arc increases chip capacity and improves efficiency.

[0012] Furthermore, a handle is provided at the end of the first bone file away from the second bone file. The handle provides a gripping point, ensuring controllability during use.

[0013] Furthermore, the end of the first bone file away from the second bone file is also provided with a gripping positioning hole. The gripping positioning hole provides a fit for gripping and ensures the stability of the grip.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0015] 1. This utility model provides a split-type bone file, which is assembled from several split-type bone file blocks. If any module is damaged, the damaged module can be replaced individually, thus improving the flexibility of bone file use.

[0016] 2. This utility model provides a split-type bone file, which enhances the connection strength through the setting of several connectors and interfaces;

[0017] 3. This utility model is a split bone file. The cutting edge is designed with a circular arc at the bottom of the groove, which increases the chip capacity and improves the efficiency of use. Attached Figure Description
