Surgical smoke removal device

Abstract

The invention discloses a surgical smoke removal device. The surgical smoke removal device comprises a shell, a negative pressure suction device, a filter, an electromagnetic pinch valve, a controllerand ultraviolet light sources, wherein the negative pressure suction device and the filter are respectively installed in the shell, the electromagnetic pinch valve is installed on the shell, the controller is installed in the shell and is respectively connected to the negative pressure suction device and the electromagnetic pinch valve, the filter includes a housing, a ULPA film, titania nets andan activated carbon filtering member, an air intake pipe hole and an air discharge pipe hole are formed in a front side plate and a rear side plate of the housing respectively, the ULPA film, one titania net, the activated carbon filtering member and another titania net are sequentially installed in the housing from the air intake pipe hole to the air discharge pipe hole, the air intake pipe holepasses through the shell and is disposed outside the shell, the air discharge pipe hole is connected to the negative pressure suction device, the ultraviolet light sources are arranged on both sidesof the left side plate and the right side plate of the housing, and the left side plate and the right side plate are transparent. According to the surgical smoke removal device, the smoke suction force is increased, and harmful substances in the smoke are purified to protect the health of medical personnel.

Description

technical field [0001] The invention relates to medical equipment, in particular to an operation smoke removal device. Background technique [0002] The use of energy products (electrosurgical technology, ultrasonic scalpel, and laser products) in the operating room has been popularized, but the smoke generated by the energy products that follow has always affected the health of operators and patients. [0003] At present, the most common way is to exhaust the smoke directly from the laparoscope to the operating room through the laparoscopic trocar, or to use the central negative pressure of the operating room to smoke during open and laparoscopic surgery, and to use special smoking equipment to purify the smoke after smoking. Excluded to the operating room. [0004] The laparoscope directly exhausts the smoke to the operating room through the laparoscopic trocar, and the exhausted smoke contains a variety of harmful substances, causing harm to medical staff; the use of cen...

AI Technical Summary

Problems solved by technology

[0004] The laparoscope directly exhausts the smoke to the operating room through the laparoscopic trocar, and the exhausted smoke contains a variety of harmful substances, causing harm to medical staff; the use of central negative pressure can suck away the surgical smoke very quietly, but for open surgery The suction is not enough, and there are problems such as difficulty in fully automatic control for laparoscopic surgery. The surgeon or assistant teacher has always manually opened and closed the exhaust valve of the laparoscopic puncture device to discharge the smoke in the abdominal cavity. If the smoke is not removed in time, the vision will be blurred. It will affect the safety of the operation; secondly, if it is excluded to the operating room, it will affect the health of the operating room teacher; thirdly, if the assistant uses a negative pressure suction device to remove the smoke, the smoke will be discharged to the negative pressure center of the hospital with the negative pressure, but the smoke has not passed through. Dealing with direct discharge, on the one hand, pollutes the negative pressure pipeline, on the other hand, if it is discharged to the hospital without treatment, it will increase the toxic and harmful substances in the hospital, which will affect the health of everyone in the hospital

Smoking with special smoking equipment has strong suction, but it is noisy, and the consumables are too expensive. The carbon dioxide used in laparoscopic surgery is exhausted into the operating room after purification, which will still affect the health of medical staff. Special smoking equipment is difficult to control. The problem is that the current special smoking equipment uses a wired detector or starts it all the time, or starts it with a foot pedal

The operating room is a special environment. There are many medical electrical equipment, so there are many connections, such as ECG monitoring, electrosurgical device connection, ultrasonic device connection, electrosurgery work connection, and nerve monitoring electrode connection in some operations. Wired detectors will increase the complexity of the connection in the operating room and make the already numerous connections look even more chaotic; secondly, if there is only one detector at the same time, it cannot be effectively controlled if the electric knife or ultrasonic knife is used at the same time, and the third is wired detection. The device makes it harder for people to walk in the already narrow operating room

If it is always activated, if the laparoscope is activated all the time, if there is no pneumoperitoneum, the vision will be lost, and the operation cannot be performed.

At present, there are usually at least two pedal-activated devices in hospital operating rooms. Not only is the connection cumbersome, but more pedals are more likely to confuse and make mistakes, which will affect the safety of the operation.
