Multifunctional shaver for laparoscopic surgery

Abstract

The invention relates to a multifunctional shaver for laparoscopic surgery. The multifunctional shaver comprises a handle assembly and a tool holder assembly, wherein the handle assembly pulls a tension rod by a handle; the tension rod pulls the tool holder assembly; a rotary wheel drives the tension rod and the tool holder assembly to rotate by 360 degrees; and the tool holder assembly provides high-frequency electric energy to tissues inside the body by taking a movable tool holder and a fixed tool holder as bipolar two ends, thereby carrying out such surgeries as electrocoagulation, incision, traction and separation. The multifunctional shaver is integrated with a plurality of important functions to carry out bipolar electric incision, bipolar electrocoagulation on the same surgical instrument, and grasp and pull tissues and fine split tissues like a common laparoscopic surgery, so that great convenience is provided for a doctor, surgical time is shortened, and a problem that the doctor frequently changes surgical instruments in the laparoscopic surgery is solved.

Description

technical field [0001] The invention relates to a multifunctional laparoscopic surgical resectator, which is specially used for resection of lesions in the abdominal cavity of a human body, and belongs to the technical field of medical instruments. Background technique [0002] Minimally invasive human laparoscopic surgery is a surgical treatment method that uses video operations to resect lesion tissue in the human body under the laparoscopic field of view. During the operation, because the surgeon's hand cannot enter the patient's body, it must rely on manipulation of various organs. Surgical instruments with various functions (such as coagulation function, cutting function, grasping and pulling function, separating tissue function, etc.) are used to complete the operation. Because a variety of surgical instruments are used in the operation, the doctor must change them frequently when necessary, which will inevitably distract the doctor's attention, increase the labor inte...

AI Technical Summary

Problems solved by technology

Surgical instruments commonly used in current laparoscopic surgery include: monopolar electrocoagulation forceps, bipolar electrocoagulation forceps, ultrasonic scalpel instruments, etc., and single-stage electrocoagulation forceps have currents passing through the human body during electrocoagulation and electric cutting. Therefore, the safety and controllability are not high, and the risk of use is relatively high. The simple bipolar coagulation forceps only has a single function of blood coagulation; the ultrasonic knife has been widely used clinically, and it can coagulate blood vessels of about 3mm while cutting tissue. , but its cutting and coagulation time is relatively long (because the lateral ultrasonic oscillation heat conduction range is large, the host must control the output power within a small range in order to reduce the lateral heat conduction), so the cutting speed is relatively slow and the coagulation effect Not ideal, and the instrument does not have a strong ability to grasp and pull tissue and finely separate tissue, it is fragile, and the price is very expensive

[0003] Chinese Patent No.: 200810062370.2, which proposes a medical bipolar coagulation forceps for electrocoagulation and hemostasis, but it can only be used for electrocoagulation without other functions. It must be used in conjunction with other surgical instruments during surgery, which affects the efficiency of surgery
