Laparoscope assembly with endoscope heating function and capable of absorbing smoke

Abstract

The invention discloses a laparoscope assembly with an endoscope heating function and capable of absorbing smoke, and belongs to the technical field of medical instruments. The laparoscope assembly comprises a laparoscope leading-in auxiliary tube, and the end part of the inner side of the laparoscope leading-in auxiliary tube is sleeved with a laparoscope leading-in main tube. According to the laparoscope assembly, a smoke drainage channel, a carbon dioxide gas leading-in channel, a clean water leading-in channel, a first flow regulating valve, a second flow regulating valve, a third flow regulating valve, a piston valve, a first one-way valve tube, a second one-way valve tube, a water storage electric heating box, a spring and other structures are designed to cooperate with each other, so that flushing requirements for an abdominal cavity operation can be met, focus tissue water shortage cannot be caused after gaseous carbon dioxide enters the abdominal cavity of a patient, and adverse reaction of focus tissue due to temperature difference is avoided; the drainage effect is good through multi-directional drainage in the whole smoke negative pressure drainage process; and the internal tissues of the abdominal cavity of the patient cannot be damaged by negative pressure.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a smoke-absorbing laparoscope assembly with an endoscope heating function. Background technique [0002] Laparoscope is similar to electronic gastroscope, which is a medical device with a miniature camera. Laparoscopic surgery is the operation performed using laparoscope and related instruments. [0003] Pneumoperitoneum is the key to the success of minimally invasive laparoscopic intervention. Before the operation, gas must be injected into the abdominal cavity to establish an artificial pneumoperitoneum to separate the peritoneal wall from the viscera. The expansion of the abdominal cavity is conducive to surgery and avoids trocar puncture. It can damage the organs when entering the abdominal cavity, and it is beneficial to the operation of surgical instruments in minimally invasive surgery. [0004] With the rapid development of minimally invasive surgery, with the he...

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the existing deficiencies in the use of the existing laparoscopic components, it is difficult for the medical staff to complete the smoke negative pressure drainage, the introduction of clean water and carbon dioxide with one hand, and in the past. The heating of the endoscope is mostly directly heated by electric heating wires, which easily deforms the endoscope due to the concentrated heating surface. In order to be able to heat carbon dioxide, gaseous carbon dioxide enters the patient's abdominal cavity and easily dehydrates the lesion tissue. And in the process of negative pressure drainage, it is easy to damage the internal tissue of the patient's abdominal cavity, and a laparoscopic component with endoscopic heating function that can absorb smoke is proposed
