Wireless nerve monitoring shear type ultrasonic knife

Abstract

The invention provides a wireless nerve monitoring shear type ultrasonic knife. The wireless nerve monitoring shear type ultrasonic knife comprises a clamp (1) and a waveguide rod (2), wherein the clamp (1) is connected with the waveguide rod (2) through an insulating pin shaft (4) to form an openable structure, and insulating sleeves (3) sleeve a clamping arm (5) of the clamp (1) and the waveguide rod (2) except a clamping part at the front end. The wireless nerve monitoring shear type ultrasonic knife is characterized in that a stimulation module (6) is mounted on a clamp handle (9) at the rear end of the waveguide rod (2); on one hand, the stimulation module (6) is electrically connected with the clamp (1) through an electrode wire, and on the other hand, the stimulation module (6) is electrically connected with the front end of the waveguide rod (2) through an electric connecting device (7), so that the clamp (1) and the waveguide rod (2) form an electromyographic signal detectionloop; and during nerve detection, the front end of the clamp (1) can send an electromyographic signal into the stimulation module (6), and finally, the stimulation module processes the electromyographic signal and sends the processed electromyographic signal into an electromyographic signal display alarm device. The wireless nerve monitoring shear type ultrasonic knife has the cutting and blood coagulation functions of the ultrasonic knife, and also has the nerve positioning function, the repeated replacement steps of instruments are reduced, and the operation time is shortened.

Description

technical field [0001] The invention relates to a medical device, in particular to a scissor-type ultrasonic knife with nerve detection function and in particular a wireless nerve monitoring scissor. Background technique [0002] Nerve injury is one of the most important complications of surgery. For example, recurrent laryngeal nerve injury can cause hoarseness or aphonia, difficulty swallowing, coughing, dyspnea or suffocation, which seriously affects the quality of life. During surgery, neuromonitoring devices are often used to monitor nerves and assist in surgery. Ultrasonic scalpel is currently the most commonly used surgical instrument in surgery. It has fast cutting speed, good hemostasis effect, simple operation, safety and convenience. Compared with the traditional use of mechanical scalpels, the use of ultrasonic scalpels in clinical practice can greatly shorten the operation time, reduce the amount of blood loss and blood transfusion of patients, thereby reducing...

Problems solved by technology

[0005] The purpose of the present invention is to aim at the simultaneous operation of tissue cutting and blood coagulation during surgery, which requires nerve positioning. The process often requires repeated stripping of the surrounding tissue and continuous nerve stimulation, which requires constant replacement. Instruments are operated, resulting in increased difficulty of surgery and prolonged operation time. A wireless nerve monitoring scissor ultrasonic scalpel is designed.
