Defogging puncture outfit for minimally invasive laparoscopic surgery

Abstract

The invention discloses a defogging puncture outfit for a minimally invasive laparoscopic surgery. The defogging puncture outfit comprises a locking cap, a sealing retainer ring, an air inlet valve, a gas center cavity, a cannula and an airflow guide cap, wherein the left end of the airflow guide cap is connected with the cannula; the gas center cavity is mounted in the left end of the cannula; the air inlet valve is mounted on the gas center cavity; and the locking cap is mounted at the left end of the gas center cavity. According to the invention, the damage to a lens of an optical sight glass due to a traditional wiping and heating mode is effectively avoided by using a gas vortex technology; due to the design of disposable materials, the risk of cross infection is avoided; a laparoscope does not need to be frequently taken out of the abdominal cavity in an operation, so that the operation time is shortened; and the visual field of the laparoscope is kept clear in the operation process, so that a doctor can complete the operation more quickly, and the surgical operation is safer and more effective.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a defogging puncture device for minimally invasive laparoscopic surgery. Background technique [0002] In minimally invasive laparoscopic surgery, due to the temperature difference between the external environment and the internal body, the mirror surface of the optical mirror is fogged, resulting in blurred images, making it impossible for doctors to perform normal operations and posing safety risks. In the current surgical situation, in order to remove the fog, the following methods are used: 1. Repeatedly take out and wipe the mirror surface; 2. Soak the lens in hot water; 3. Use light heat source heating method. The current treatment method will produce many adverse consequences: Wiping method: Because it needs to be taken out repeatedly, the operation time is prolonged and the doctor is confused. Because the optical mirror needs to be repeatedly wiped, the mirror su...

AI Technical Summary

Problems solved by technology

The current treatment method will have many adverse consequences: Wiping method: because it needs to be removed repeatedly, it will prolong the operation time and cause confusion for doctors

Due to the need to repeatedly wipe the optical mirror, the mirror surface is damaged, which affects the service life of the optical mirror

Boiling water heating and soaking method: It also needs to be taken out and heated and soaked repeatedly, which will lengthen the operation time and make it difficult for doctors to operate

At the same time, due to intermittent boiling water heating, thermal expansion and contraction will cause the epoxy resin seal of the optical mirror to fall off, resulting in water ingress into the light column and damage to the optical mirror.

Lamp heating method: cross-infection is easy to occur, and at the same time, due to thermal expansion and contraction caused by intermittent heating, the epoxy resin seal of the optical mirror will fall off, resulting in water leakage, damage to the optical mirror and expensive equipment
