Electrotome used for incising pericardium under endoscope

Abstract

The invention discloses an electrotome used for incising the pericardium under an endoscope. The electrotome comprises a guide rod and a handle connected to one end of the guide rod. A gear switch is installed on the handle. The guide rod is a hollow tube. One end of the guide rod is fixedly connected with the end of a long-strip-shaped plastic plate. The plastic plate and the guide rod are arranged in an obtuse-angle mode. A guide wire hole is formed in the connecting portion of the plastic plate and the guide rod. A metal guide wire is fixedly arranged at the other end of the plastic plate. The metal guide wire enters along the guide wire hole and is connected with the gear switch installed on the handle, the gear switch pokes and pulls the metal guide wire to be tightened, and the tightened metal guide wire enables the plastic plate to be in an arch-shaped working state. The gear switch is connected with an external power source through a wire. The electrotome can incise the pericardium efficiently and conveniently, the strutting space is enough, risks in surgery can be reduced greatly, and surgery operation is facilitated.

Description

technical field [0001] The invention relates to a cardiothoracic surgical instrument, in particular to an electric knife for incision of the pericardium under an endoscope, belonging to the technical field of medical instruments. Background technique [0002] The pericardium is a tough film that surrounds the heart. There is serous fluid between the pericardium and the heart, which acts as a lubricant and reduces friction with the pericardium when the heart moves. Cardiac surgery requires incision of the pericardium. Usually, electric knife is used for incision. During the incision, the electric knife head is strictly forbidden to touch the heart to prevent ventricular fibrillation or perforation of the heart. Serious consequences; if in traditional open surgery, double operation can be used to effectively reduce the risk, but in minimally invasive surgery, usually only one surgeon can complete the operation, and the doctor needs to separate carefully, which has a great impa...

Cardiac surgery requires incision of the pericardium. Usually, electric knife is used for incision. During the incision, the electric knife head is strictly forbidden to touch the heart to prevent ventricular fibrillation or perforation of the heart. Serious consequences; if in traditional open surgery, double operation can be used to effectively reduce the risk, but in minimally invasive surgery, usually only one surgeon can complete the operation, and the doctor needs to separate carefully, which has a great impact on the Doctors have high requirements for skills and physical strength, because once an accident occurs, it will directly affect the life safety of the patient

[0003]In recent years, the electric cutter for skin and subcutaneous tissue incision and stripping has been widely used in surgical operations, and good therapeutic effects have been achieved. This type of electric cutter is only It is more convenient in traditional open surgery. Although it is widely used in minimally invasive surgery, when the electric knife is used in minimally invasive cardiac surgery, the operating space is small and the field of vision is not wide enough. The high requirements eventually lead to a longer operation time and a lot of physical exertion for the doctor
