Description

A disposable abdominal puncture device

Technical Field

The utility model belongs to the technical field of medical equipment, and in particular relates to a disposable abdominal puncture device.

Background Art

Laparoscopic puncture device is a disposable device suitable for the delivery of gas in minimally invasive surgery and the creation of channels for endoscopes and surgical instruments to enter and exit the body cavity from the outside. Various laparoscopic surgeries, including minimally invasive surgery, gynecological minimally invasive surgery, thoracic surgery, urology and other laparoscopic surgeries, can be matched with various laparoscopic TV systems at home and abroad. With the improvement of national living standards, doctors and patients have higher and higher demands for minimally invasive surgery. At the same time, in order to avoid cross infection, laparoscopic puncture devices are all designed to be disposable, so the market for laparoscopic puncture devices is getting bigger and bigger.

Laparoscopic puncture instruments will produce surgical smoke during the operation. The main components of surgical smoke are: harmful chemical components, active viruses, active cells, inactive particles, substances that induce mutations, etc. At the same time, during the puncture process, some liquid components in the abdominal cavity, including blood, tissue fluid, etc., will be carried out through the puncture instrument. These gas and liquid components will be mixed together and discharged together when the puncture rod in the puncture instrument is pulled out. This often causes some pollution problems. The gas component will not only reduce the clarity of the surgical field and affect the operation of the operation, but also release toxic and harmful substances, endangering the health of the operating room personnel and polluting the atmosphere. The liquid component will also affect the operation of the operation. These are all problems that need to be solved in clinical and environmental protection.

The utility model provides an adsorption and filtering structure inside the puncture rod, so that during the puncture process, the discharged gas and the carried liquid can be filtered and adsorbed conveniently and quickly, without affecting the progress and operation of the operation. When the puncture rod and the puncture sleeve pass through the abdominal wall and enter the abdominal cavity, under the action of negative pressure, the gas and a small amount of liquid enter the filter cavity through the second cavity and the first cavity, and the harmful components in the gas are absorbed by the adsorption layer in the filter cavity and discharged through the exhaust pipe. The small amount of liquid components are absorbed by the internal absorbent fiber when passing through the filling cavity in the first cavity. When the puncture rod is pulled out of the puncture sleeve, the discharge of harmful gas and a small amount of liquid is reduced, which will not affect the health of medical staff and will not pollute the environment. The gas and liquid components discharged during the puncture operation are quickly filtered and absorbed by the puncture device itself, which reduces the difficulty of the operation and improves the quality of the operation.
