Water feeding and discharging pressure stabilizing device suitable for endoscopic surgery and control method for water feeding and discharging pressure stabilizing device

Abstract

The invention relates to the technical field of medical equipment, and provides a water feeding and discharging pressure stabilizing device suitable for endoscopic surgery and a control method for the water feeding and discharging pressure stabilizing device. The water feeding and discharging pressure stabilizing device comprises a water feeding pump assembly and a water discharging pump assembly, the water feeding pump assembly and the water discharging pump assembly communicate with an endoscopic outer sleeve through water pipes correspondingly, and the water feeding pump assembly and the water discharging pump assembly are electrically connected to a water feeding and discharging controller. According to the water feeding and discharging pressure stabilizing device, the water feeding pump assembly and the water discharging pump assembly are electrically connected to the same water feeding and discharging controller, cooperative action of the water feeding pump assembly and the water discharging pump assembly can be controlled by operating the water feeding and discharging controller during surgery, the water feeding/discharging amount during surgery is controlled in real time, one-key water changing is realized, and therefore tedious operation during surgery is avoided, the workload of medical staff is reduced, the medical staff can better concentrate on the operation of the surgery, and the continuity and smoothness of the surgery are ensured.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an inlet and drain pressure stabilizing device suitable for endoscopic surgery and a control method thereof. Background technique [0002] With the development of minimally invasive surgical techniques, arthroscopic surgery has become an important means of diagnosis and treatment in bone and joint surgery in my country. However, because there is not enough operating space in the joint, rich blood vessels, and easy bleeding during the operation, the water inlet and drainage system in the operation is an important part of the success of arthroscopic surgery, which directly affects the clarity of the surgical field of view and the pressure in the joint cavity. stability. The water inlet and drainage system uses a certain pressure of sterile saline to continuously perfuse the joint cavity, expand the gap in the joint cavity, increase the pressure of the joint cavity, reduc...

AI Technical Summary

Problems solved by technology

[0007] The present invention aims at the current water exchange process in the joint cavity. The operator manually unscrews the water inlet / outlet valve to realize the water exchange, but the manual operation steps are cumbersome, which is not conducive to the continuity of the operation, thus increasing the operation time and affecting the state of the operator. , and virtually increased the workload of medical staff; the purpose of the invention is to provide a more convenient operation for medical staff, and can effectively reduce the workload of medical staff, effectively ensure the continuity of surgery suitable for endoscopic surgery Drain pressure stabilizing device
