Description

Technical Field

[0001] The invention relates to a bone reamer, in particular to a novel bone reamer. Background Art

[0002] A bone reamer is a medical device used in orthopedic surgery. It is mainly used to ream holes in bones that have been drilled. Bone reamer is an indispensable tool in orthopedic surgery. Its design and manufacturing standards are strict to ensure the safety and success of the operation12.

[0003] Bone reamers in the prior art currently have the following disadvantages: 1: Safety, the cutting edge is prone to secondary damage during use; 2: Cutting edge identification, it is inconvenient to identify the direction of the reamer cutting edge; 3: Good operating performance, the round handle is inconvenient to operate. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a new type of bone reamer in view of the deficiencies mentioned in the above background technology.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is: a new type of bone reamer, including a bone reamer head, a bone reamer rod and a bone reamer handle that are fixedly connected to each other, the cutting edge position of the bone reamer head is blunted, the bone reamer handle is triangular, and the longer corner of the bone reamer handle is set to align with the cutting edge direction of the bone reamer head.

[0006] Furthermore, an endoscope observation window is provided in the middle of the bone reamer head, and both the bone reamer rod and the bone reamer handle are provided with an endoscope channel connected to the endoscope observation window.

[0007] Compared with the prior art, the advantages of the present invention are: 1. Safety, all sharp edges of the cutting edge are blunted to prevent secondary damage during use;

[0008] 2: Blade identification: the long handle of the reamer is directly opposite to the reamer blade, and the direction of the reamer blade can be identified through the handle;

[0009] 3: Good operating performance, the handle is designed in a triangular shape, and the handle can be easily turned during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a three-dimensional structural schematic diagram of a novel bone reamer of the present invention.

[0011] Figure 2 It is a front view structural schematic diagram of a novel bone reamer of the present invention.

[0013] As shown in the figure: 1. Bone reamer handle; 2. Bone reamer rod; 3. Bone reamer head; 4. Endoscope observation window; 5. Endoscope channel. DETAILED DESCRIPTION

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0015] Combined with Figure 1-3 A new type of bone reamer includes a bone reamer head 3, a bone reamer rod 2 and a bone reamer handle 1 that are fixedly connected to each other. The three parts are combined together by welding. The cutting edges of the bone reamer head 3 are all blunted. The bone reamer handle 1 is triangular in shape. The longer corner of the bone reamer handle 1 is aligned with the cutting edge direction 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 edges are blunted to ensure that the bone reamer can work normally and will not cut other human tissues.

[0016] An endoscope observation window 4 is provided in the middle of the bone reamer head 3, and both the bone reamer rod 2 and the bone reamer handle 1 are provided with an endoscope channel 5 connected to 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 are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
