Pair of bipolar electric coagulation forceps with nerve stimulation function

Abstract

A pair of bipolar electric coagulation forceps with a nerve stimulation function comprises a forceps handle (1), an insulating layer is coated on a handle body of the forceps handle (1), the front endof the forceps handle (1) is a metal conductive end, and the tail end of the forceps handle (1) is fixed on an operating handle (6) and is electrically connected with a pedal-controlled high-frequency generator through a high-frequency cable (5). The pair of bipolar electric coagulation forceps is characterized in that a nerve monitoring button(2) is arranged on the operating handle (6); the stimulation module (3) is electrically connected with the subcutaneous electrode (4) while being electrically connected with the forceps handle (1) through the nerve monitoring button (2), and when the nerve monitoring button (2) is pressed down, the forceps handle (1) serves as a nerve detection needle to send detected electromyographic signals into the electromyographic signal monitor together withthe subcutaneous electrode (4) for an operator to read the nerve position. The device has a cutting and blood coagulation function and a nerve positioning function, repeated replacement steps of instruments can be greatly reduced, and the operation time is shortened.

Description

Technical field[0001]The present invention relates to a medical device, in particular a medical surgical instrument that combines electrocoagulators and neurodus, specifically a bipolar coagular condensation with neurostimulating function.Background technique[0002]Nerve injury is one of the most important complications of surgery. For example, the laryngeal nerve injury will cause hoarseness or loss of swallowing, difficulty in swallowing, difficulty breathing or suffocation, and serious affecting the quality of life. In surgery, a nerve monitoring is often used to monitor nerves and help surgery. Bipolar Caggery is currently the most common surgical instrument in surgical surgery, which has a fast cutting speed, good stop bleeding effect, simple operation, safe and convenient. Compared with the traditional mechanical surgery knife, it can greatly shorten the operation time in clinically, reduce the blood loss and blood transfusion volume, thereby reducing complications and surgical...

Problems solved by technology

[0005] The purpose of the present invention is to aim at the operation of tissue cutting and coagulation when performing nerve positioning. The process often requires repeated stripping of the surrounding tissue and continuous nerve stimulation, which requires constant replacement of instruments for operation, resulting in increased difficulty of surgery Design of a bipolar coagulation forceps with monopolar nerve monitoring function for extended operation time in Yamato
