Surgical biopsy scalpel

Abstract

The invention discloses a surgical biopsy scalpel. The surgical biopsy scalpel is characterized by comprising an outer cutter pipe, an inner cutter head and a driving pipe, wherein the inner cutter head is sleeved with the outer cutter pipe, the outer cutter pipe is provided with an outer cutter edge, the inner cutter head is provided with an inner cutter edge, the inner cutter head is provided with an accommodating cavity communicating with the inner cutter edge, the driving pipe is connected with the inner cutter head to drive the inner cutter head to rotate or horizontally move relative tothe outer cutter pipe, a moving cavity is arranged between the end of the outer cutter pipe and the end of the inner cutter head, and a first position-limiting block, a second position-limiting block,a first position-limiting groove and a second position-limiting groove are arranged between the inner cutter head and the outer cutter pipe. According to the surgical biopsy scalpel provided by the invention, rotary cutting or horizontal cutting can be selected in a biopsy sampling process, and a sample is not easy to fall off.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a surgical biopsy scalpel. Background technique [0002] For the biopsy of diseased tissue, only the complete central part has the highest diagnostic value. Minimally invasive surgery is welcomed by the majority of patients because of its small trauma, light pain, quick recovery, and less scarring. In recent years, the incidence of thyroid disease, breast disease, intestinal disease, etc. has surged, so cutting samples for biopsy is often used to help patients determine whether the cells in the examined area are cancerous. [0003] Samples can be obtained well through a minimally invasive scalpel. Existing scalpels can be divided into two types: rotary cutting or flat cutting. The cutting method is decided before the operation, and it is difficult to replace it after entering the tissue. If the cut sample is not handled properly, it is easy to stay outside the cutting knife a...
