Irrigation and suction tube and surgical device

Abstract

The invention discloses a flushing suction tube and a surgical device.The flushing suction tube comprises a tube body and a tube connector assembly, the tube connector assembly is provided with a first connector, a second connector and a third connector, a drainage channel, a liquid conveying channel and a gas conveying channel are formed in the tube body, and the drainage channel penetrates through the two ends of the tube body; a pipe joint assembly is arranged or integrally formed at the near side end of the pipe body, the first joint is communicated with the exhaust channel, the second joint is communicated with the liquid conveying channel, the third joint is communicated with the gas conveying channel, and a pipe opening structure of the pipe body is provided with a first smoke exhaust structure communicated with the exhaust channel; a liquid spraying hole and an air spraying hole are formed in the positions, close to the pipe opening structure, of the pipe body, the liquid spraying hole is communicated with the liquid conveying channel, and the air spraying hole is communicated with the air conveying channel. The smoke exhaust device can exhaust smoke and clean the lens of the endoscope, so that the safety and continuity of an operation are ensured, and the health of a patient and medical staff in the operation is ensured.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a flushing suction tube. Furthermore, it also relates to a surgical device. Background technique [0002] With the rapid development of medical technology, people not only require surgery to cure diseases, but also hope to reduce the damage caused by the surgery itself to achieve minimally invasive surgery, such as laparoscopic surgery. Establish surgical access to reduce damage to patients. Laparoscopic surgery is highly instrument-dependent. The application of energy instruments such as monopolar and bipolar energy instruments is indispensable in surgical cutting and hemostasis. [0003] At present, most energy devices use thermal energy or high-speed and low-frequency oscillating mechanical energy to cause protein denaturation. During this process, a large amount of smoke will be generated. Problems caused by smoke generation: 1. Affect the safety of surgery: a large amount o...

AI Technical Summary

Problems solved by technology

Problems caused by smoke generation: 1. Affect the safety of surgery: a large amount of smoke hinders the surgical field of view, blurs the operation area, and affects the safety of surgical operations; 2. Affects the continuity of surgery, increases the cost of operation time, and sometimes needs to suspend the operation. The surgical operation can only be continued after the smoke dissipates and the surgical field of view is clear; 3. Potential hazards to the health of patients undergoing surgery, doctors and nurses participating in the surgery: surgical smoke contains a variety of harmful chemical components (organic or inorganic compounds), and even Carcinogens, some scholars have found at least 4 clear carcinogens in surgical smoke: 1,3-butadiene, hydrogen cyanide, acetylene, organic benzene. Peritoneal absorption, some studies have found that in the urine of laparoscopic surgery patients, benzene and toluene were detected significantly increased, which is not conducive to post-operative recovery, and even has potential hazards to the health of patients; 4. Hazard to the health of surgeons: surgical smoke In addition to the harmful or carcinogenic substances mentioned above, strong odors and infectious biological particles can also be produced. Some studies have reported that the smoke produced by electrosurgical treatment of 1g of human tissue is equivalent to the harmfulness of 6 unfiltered cigarettes inhaled by the human body.

In addition, harmful substances (styrene, teratogens, etc.) can directly enter the body through the eyes and other parts, causing damage to the human body

Also, in laparoscopic techniques, the lens of the laparoscope is often contaminated with peritoneal or other bodily fluids, blood, aerosolized fat, tissue particles, smoke, debris, or condensation that can interfere with the physician's field of view (via an external monitor)
