Abstract
Description
Technical Field
[0001] This utility model relates to a bone reamer, specifically a novel bone reamer. Background Technology
[0002] A bone reamer is a medical device used in orthopedic surgery. It is mainly used to ream holes in pre-drilled bones. Bone reamers are an indispensable tool in orthopedic surgery, and their design and manufacturing standards are strict to ensure the safety and success of the surgery.
[0003] The existing bone reamer technology has the following disadvantages: 1. Safety: the blade edge is prone to secondary damage during use; 2. Blade edge identification: it is not convenient to identify the direction of the reamer blade edge; 3. Good operation performance: the round handle is inconvenient to operate. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a novel bone reamer, addressing the shortcomings mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a novel bone reamer, comprising a bone reamer head, a bone reamer rod, and a bone reamer handle that are fixedly connected to each other, wherein the cutting edge of the bone reamer head is blunted, and the bone reamer handle is triangular, with the longer corner of the bone reamer handle aligned with the direction of the cutting edge of the bone reamer head.
[0006] Furthermore, the bone reamer head is provided with an endoscope viewing window in the middle, and both the bone reamer rod and the bone reamer handle are provided with an endoscope channel communicating with the endoscope viewing window.
[0007] The advantages of this utility model compared with the prior art are: 1. Safety: all sharp edges at the cutting edge are blunted to prevent secondary damage during use;
[0008] 2: Edge identification: The long handle of the reamer is directly opposite the reamer edge, and the direction of the reamer edge can be identified by the handle;
[0009] 3. Excellent operability: The handle is designed in a triangular shape, making it easy to turn during use. Attached Figure Description

[0013] As shown in the figure: 1. Bone reamer handle; 2. Bone reamer rod; 3. Bone reamer head; 4. Endoscopic viewing window; 5. Endoscopic channel. Detailed Implementation
[0014] The present invention will now be described in further detail with reference to the accompanying drawings.
[0015] Combined with appendix Figure 1-3 A novel bone reamer includes a bone reamer head 3, a bone reamer rod 2, and a bone reamer handle 1, which are fixedly connected to each other. The three parts are assembled together by welding. The cutting edges of the bone reamer head 3 are all blunted. The bone reamer handle 1 is triangular in shape, with the longer angle of the handle 1 aligned with the cutting edge of the bone reamer head 3. When the bone reamer handle 1 is rotated, the bone reamer head 3 rotates together, and all sharp edges of the cutting edge are blunted, ensuring that the bone reamer can work normally without cutting other human tissues.
[0016] The bone reamer head 3 is provided with an endoscope observation window 4 in the middle. The bone reamer rod 2 and the bone reamer handle 1 are both provided with endoscope channels 5 that communicate with the endoscope observation window 4. An endoscope is inserted through the endoscope channel 5, and the working environment of the cutting edge can be seen through the endoscope observation window 4.
[0017] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
