Abstract

The invention provides a medical tool. The medical tool comprises a tool handle, a tool body and a drill bit; the too body is provided with a side cutting blade, one end of the tool body is connectedwith the tool handle, the other end of the tool body is connected with the drill bit, and the drill bit and the tool body are coaxially arranged. The drill bit and the tool with the side cutting bladeare integrated on one structure, and it can be guaranteed that when drilling and hole enlarging or hole repairing are conducted in the operation process, central axes can coincide completely. Therefore, the medical tool is good in self-centering and guiding, holes higher in precision can be machined, and tedious aiming and aligning operations are not needed in the punching process, so that the operation process of punching is simplified, and the punching efficiency is improved; in addition, the punching precision is higher.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a cutter for opening holes in biological tissues such as bones. Background technique [0002] A reamer for orthopedic surgery is a rotary cutter with a handle and multiple cutting edges for modifying the surface of the bone marrow cavity. Reamers and drills are commonly used when performing orthopedic surgery. Drills and reamers are two separate tools that are used separately. First use a drill to locate and punch holes in the bone, and then use a reamer to ream or repair the holes. This way of use leads to the need to align the original drill bit when reaming or repairing the hole, so that the central axes coincide. However, the existing medical reamers are poor in self-centering and guiding, and the alignment operation is difficult, and the accuracy of the drilled holes is difficult to guarantee. Moreover, the existing reamers for orthopedics also have the follo...
