Description

Anti-slip surgical scissors

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to anti-skidding surgical scissors.

Background

The surgical scissors are medical instruments commonly used in clinical operations and mainly used for cutting off coarse soft tissues such as skin or muscles. It can also be used to separate tissue, i.e. using the tip of scissors to insert into the tissue space, to separate connective tissue without large blood vessels, etc. Current surgical scissors is made for pure metal usually, but pure metal scissors surface is more smooth, easy slippage, it has greatly increased the work degree of difficulty to give medical staff, so the surgical scissors of taking the plastic handle of a knife has appeared on the market, but current surgical scissors of taking the plastic handle of a knife, the plastic handle of a knife is connected or bonds with the handle of a knife by moulding plastics, such connected mode leads to whole scissors can not carry out high temperature disinfection, so generally adopt alcohol to soak the disinfection, and alcohol soaks and leads to the tool bit to rust easily again or the oxidation, to these problems, we have designed an antiskid surgical scissors.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: aims to provide an anti-skid surgical scissors which is used for solving the problems existing in the background technology.

In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
