Description

Homemade smoke suction filter for open surgery

Technical Field

The utility model specifically relates to the technical field, in particular to a self-made smoke suction filter for open surgery.

Background Art

Laparoscopic surgery has gradually replaced traditional open radical surgery for cervical cancer due to its advantages such as less trauma and faster recovery. With the development of medical technology, the use of tools such as high-frequency electric knives and ultrasonic knives has become more and more frequent. A large amount of surgical smoke will be generated during the operation. Authoritative organizations have confirmed that surgical smoke has potential hazards to human health and will bring serious health risks to medical staff. In response to this, many hospitals at home and abroad now use disposable smoke filters specifically for laparoscopy. The filter is effective in the early stage of the operation, but in the later stage, due to the long operation time and untimely water discharge, the expensive smoke filter needs to be replaced frequently, which excessively increases the cost of surgery.

In the prior art, a homemade smoke suction filter for open surgery includes a suction tube, one end of which is provided with a suction port and a suction hole, and the other end is provided with a suction device connecting pipe connected to a negative pressure suction device, the inner cavity of the suction tube is provided with a jacket, the jacket divides the inner cavity into a smoke removal chamber and a liquid suction chamber, the jacket is spaced a certain distance from the suction hole, a plurality of smoking holes connected to the smoke removal chamber are provided on the suction tube corresponding to the jacket, a smoke exhaust pipe connected to the smoke removal chamber is provided on the suction tube, the smoke exhaust pipe is connected to the suction device connecting pipe through a switching valve, and a switch for controlling the switching valve is provided on the suction tube.

The beneficial effects of the utility model are:

1. Cut a small hole on pipe a at a distance of 2ml, that is, an opening, and then insert the electric knife head through the opening, thus forming a suction device dedicated to the open operating table. Remove the protective cap of the connector b at the other end, and pour sterile injection water into the chest closed drainage bottle to filter the cancer cells in the smoke, and connect it to the air inlet of the chest closed drainage bottle (at this time, negative pressure has been formed in the chest closed drainage bottle). Use the central negative pressure equipment to make pipes c and d generate attraction, and continuously absorb smoke when it appears, and filter it through the filter, and then discharge it directly into the atmosphere. Simply put, the smoke must first go through the sterile injection water and then go through the filter for dual effects. The assistant or instrument nurse on the table can help open the regulator and adjust the size of the suction force, so as to effectively suction the smoke generated in the operating area in all directions. At the same time, the smoke gas filtered by the filter in the negative pressure drainage bottle can be discharged freely, thereby achieving the effect of continuous negative pressure of the negative pressure suction device, and timely eliminating the smoke and carbon dioxide waste gas during the operation, avoiding the pollution of the atmosphere by unpurified gases, and ensuring the operator's clear surgical field of view, shortening the operation time, and improving the operation efficiency and safety.
