Safe and automatic puncture outfit for endoscopic surgery

Abstract

A safe and automatic puncture outfit for endoscopic surgery is characterized by comprising a channel assembly, a limiting device and a puncture needle, wherein the puncture needle comprises a holding part, a needle body and a lead screw driving device; the needle body comprises a needle body casing and a hollow needle rod arranged in the needle body casing; the lead screw driving device is arranged in the needle body casing and connected with the hollow needle rod and comprises a drive motor, a lead screw and a lead screw nut; the drive motor is arranged at the top of the inner side of a pillow body casing and is connected with the lead screw; the lead screw extends into the hollow needle rod; the lead screw nut is nested on the lead screw, connected with the inner side wall of the hollow needle rod and driven by the lead screw to perform linear reciprocating motion; the puncture outfit further comprises a rotating system which comprises a rotating motor, a miniature rotating encoder and a control system. The safe and automatic puncture outfit can realize automatic puncture, has practical and reliable functions and can maintain constant carbon dioxide pressure of an operating cavity while intelligently releasing smoke in a puncture tube and an operating field.

Description

technical field [0001] The invention relates to a safe automatic laparoscopic surgery trocar, in particular to a practical and reliable safe automatic laparoscopic surgery trocar which intelligently releases the puncture tube and the smoke in the operation field and maintains a constant carbon dioxide pressure in the operation cavity. Background technique [0002] Laparoscopic surgery has less pain, faster recovery, shorter hospital stay, and improved cosmetic effect. It is a revolution in surgery, and the technology is becoming more and more perfect and mature. The concept of minimally invasive surgery has gradually been accepted by medical staff and patients. [0003] Laparoscopic surgery is a surgical method with the help of camera system, light source and instruments. It uses various types of puncture devices to establish an operation channel at the surgical site, and then uses special lengthened surgical instruments to complete the operation under the monitor of the TV....

AI Technical Summary

Problems solved by technology

[0004] The puncture tube is composed of a support channel body with a support channel. One end of the puncture tube is provided with a limit ring, and the other end of the puncture tube is connected with the support channel. A sealing ring is fixed in the support channel. Both ends of the flushing valve are connected to the flushing valve. The tube is fixedly connected, the flushing tube is fixedly connected with the supporting channel, and the puncture needle sleeve is inserted into the supporting channel, wherein the sealing ring is sealed and matched with the puncture needle; the disadvantages of this structure are: first, the outer wall of the puncture tube is smooth, and it is easy to Slip occurs, which affects the operation; second, during the operation, it is necessary for the assistant to turn the valve from time to time to discharge the smoke or the main operator frequently replaces the suction device to suck out the smoke, which is cumbersome and prolongs the operation time; Difficult to control the time, resulting in insufficient carbon dioxide pressure in the operation chamber; Fourth, the puncture is manual operation, and the operation process is more affected by human subjective factors
