Anti-shake scalpel

Abstract

The invention provides an anti-shaking scalpel. The anti-shaking scalpel comprises a scalpel handle. The scalpel handle comprises a scalpel handle rod and a scalpel handle seat. The scalpel handle seat is in a rod shape, and an insertion channel is formed in the scalpel handle seat along the axis. The front end of the scalpel handle rod is fixed to a scalpel head, and an insertion rod inserted into the insertion channel is formed at the rear end of the scalpel handle rod. One or more sets of sliding plug holes are formed in the insertion channel. Each set comprises two or more sliding plug holes circumferentially distributed about the axis of the insertion channel. The axes of the sliding plug holes and the axis of the scalpel handle rod are orthogonal. Sliding plugs are arranged in the sliding plug holes, elastic mechanisms are arranged at the bottoms of the sliding plugs and the sliding plug holes, and the elastic mechanisms enable the sliding plugs to stretch out of the sliding plug holes to abut against the surface of the insertion rod of the scalpel handle rod. Gaps are reserved between the scalpel handle rod and the inner surface of the insertion channel and between the scalpel handle rod and the front end face of the insertion channel. According to the scalpel, the scalpel head can resist slight hand shaking, and therefore surgical quality is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular, a scalpel. Background technique [0002] A scalpel is a commonly used medical instrument; a common scalpel includes a handle and a head. After the head is assembled on the handle, it is fixed with the handle. After use, the head is discarded, and the handle can be reused. In actual use, different surgical requirements are often encountered, such as the need for different lengths of cutter heads according to the specific surgical location, which has been given a solution in the patent application No. 2013201146035; and in the actual operation During the process, for novices, there may be hand shaking due to nervousness, so that the cutter head will follow the hand shaking, which may seriously affect the quality of the operation. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an anti-shake scalpel, which can ma...
