Handle of nano ceramic scalpel

Abstract

Conventional scalpels are relatively good in elasticity and tenacity and are clamped in an embedded mode; while a nano biological ceramic scalpel is quite thin, which is just 0.3-0.5mm, high in fragility, relatively poor in tenacity and can become broken quite easily, and a conventional embedded clamping mode is not suitable for clamping the nano biological ceramic scalpel. In order to solve a problem in fixing between a blade and a handle of an existing ceramic scalpel, the invention provides a novel clamped handle of a nano biological ceramic scalpel, namely a clamped handle, wherein the handle comprises a long handle 1 and a short handle 2, wherein a mounting groove 1-2, in which a blade 3 is arranged, is formed in the front end of the long handle; bosses 4, which are provided with through holes, are arranged on both the long handle 1 and the short handle 2; a fixed shaft 5 is inserted in the through holes; a spring 6 is arranged on the shaft 5; the spring 6 is fixedly arranged between the long handle 1 and the short handle 2, so that the front end of the spring is kept under a contacted state; the tail of the short handle is pressed and the front end of the short handle gets separated from the long handle when the blade needs to be mounted, the blade is placed in the mounting groove, and then the short handle is reset, so that the blade is clamped. The scalpel provided with the handle is convenient to use; and the scalpel is widely applicable to various surgical operations.

Description

technical field [0001] The invention belongs to the field of medical equipment. In particular, it relates to the design and manufacture of a nano-ceramic scalpel handle. Background technique [0002] Among the many surgical instruments, the scalpel is undoubtedly the most used one. At present, most of the surgical blades commonly used in clinic are made of carbon steel. Although this kind of scalpel can basically complete surgical cutting, there are many shortcomings of metal materials, such as poor biocompatibility, easy to rust, and rough surface. , surface charge, poor sharpness, etc. These problems cause strong inflammatory reactions in surgical incisions and affect incision healing. The use of bioceramics to make scalpels can avoid active bleeding on the cutting surface, shorten the time of ligation and hemostasis, and make the incision heal quickly without obvious cut marks. It can be widely used in ophthalmology, plastic surgery, vascular surgery, microsurgery, neur...
