Novel bone mallet

Abstract

The invention discloses a novel bone mallet, comprising a mallet body, wherein the mallet body is connected with a hand shank through a connecting rod; the section of the hand shank is rectangular; filing teeth are arranged at two sides of the part, which protrudes towards two sides, on the hand shank; a groove is formed in the upper surface of the hand shank along the length direction; the tail end of the groove is connected with a periosteum separating arm through a rotating shaft; a pluggable pin shaft is arranged inside the groove in the upper part of the periosteum separating arm; the periosteum separating arm can be rotatably arranged inside the groove around the rotating shaft and is positioned through the pin shaft. By adopting the novel bone mallet, various orthopedic medical devices, such as the bone mallet, the periosteum separating arm and bone files are integrated, so that medical staff reduce the frequency of looking for and exchanging surgical instruments in the orthopaedic treatment process, thereby improving the work efficiency; the periosteum separating arm can be hidden into the groove in the hand shank, so that the space is fully utilized, and the novel bone mallet is simple and small in model, and convenient to use.

Description

technical field [0001] The invention relates to medical instruments, in particular to a novel bone hammer. Background technique [0002] At present, the surgical instruments used in orthopedics generally often need to use bone mallets, periosteal separators and bone rasps. In the prior art, the clinically used bone mallets, periosteal separators and bone rasps are three different types Utensils need to be searched and replaced respectively in the tool box during use, which is very cumbersome to operate in the medical process, time-consuming and laborious, low work efficiency, and increases the workload and work difficulty of medical staff. Contents of the invention [0003] In order to solve this problem in the above-mentioned technologies, the present invention provides a new type of bone mallet that integrates a bone mallet, a periosteal separation arm and a bone file, and the periosteal separation arm can be hidden. The structure is simple, the design is lightweight and...
