thoracic surgery scalpel

Abstract

The invention discloses a scalpel for the department of thoracic surgery. The scalpel comprises a scalpel handle, a scalpel head, a scalpel body, a first web pad, a sliding button and a controller, wherein the scalpel head is fixedly connected to one side of the scalpel handle, a scalpel blade is arranged at the bottom of the scalpel head and provided with sawtooth blade bodies, the sawtooth blade bodies are provided with blood sucking inlets, the scalpel body is fixedly connected to the other side of the scalpel handle, the first web pad is fixedly connected to one side of the scalpel body, a blood collecting sac is arranged inside the first web pad, an outlet plug is arranged on one side of the blood collecting sac, and a lithium battery is arranged inside the scalpel body. The blood sucking inlets are formed in two sides of the sawtooth blade bodies and are connected to the blood collecting sac through first guide tubes, and the sliding button is pushed and pulled through a guide rail to drive a plunger to reciprocate in a second guide tube to form negative pressure, and the blood collecting sac sucks blood from the blood sucking inlets, so that doctors can conveniently observe wound states during operations. The scalpel for the department of thoracic surgery is novel in design and integrates the sawtooth blade bodies on the blade to make the cutting edge sharper, so that hard tissues can be incised easily.

Description

technical field [0001] The invention relates to a medical device, in particular to a surgical knife for thoracic surgery. Background technique [0002] Surgery is an important factor in determining the effect of treatment, and the main process of surgery is to use a scalpel to incise, separate tissues and remove lesions.

At present, the clinically used thoracic surgery scalpels are mainly composed of a knife body and a knife handle. This kind of scalpel is only suitable for cutting soft tissues, while thoracic surgery often needs to cut bones, cartilage, etc., which requires replacement of various Utensils are very troublesome to operate, time-consuming and labor-intensive, which adds great difficulty to the medical staff, and in the process of cutting, the surgical site bleeds, causing the doctor's sight to be blocked, unable to observe the situation of the cutting site in time, and delaying the operation time. It causes troubles to patients and doctors. In order to solve the above problems, other scalpels have added many parts and take up a lot of space, which makes the operation of the scalpel troublesome. At the same time, it is difficult to operate in a small wound, and the wound must be enlarged. But this will cause more harm to patients
