Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to puncture ware for laparoscopic surgery with function of discharging fume.

Background

In minimally invasive surgery, pneumoperitoneum is required to be performed in the abdominal cavity of a patient. The pneumoperitoneum is an important link in the laparoscopic surgery, and the laparoscopic puncture outfit is a medical instrument for building the pneumoperitoneum. Good air tightness and air resistance are the basis for establishing pneumoperitoneum, and CO2 gas is injected into a human body through an air injection valve on the puncture outfit to form the pneumoperitoneum.

The puncture outfit for the laparoscope mainly comprises a puncture sleeve, a sealing assembly, a puncture rod and an air injection valve, wherein after the puncture rod is inserted into the sealing assembly and the puncture sleeve, the sealing assembly can seal an insertion channel of the puncture rod, so that foreign matters in the environment, particularly infection sources, are prevented from entering the body of a patient from the puncture sleeve, and meanwhile, gas in the abdominal cavity is prevented from overflowing outwards. The gas injection valve is fixed with and communicated with the puncture cannula, and the gas injection valve is used for connecting with a CO2 gas supply device so as to inject CO2 gas into the abdominal cavity of the operated person to establish pneumoperitoneum. The gas injection valve has two working states of opening and closing, the gas injection valve can be opened only during gas injection, and the gas injection valve is in the closed state under other conditions, so that foreign objects, particularly infection sources, are prevented from entering the puncture outfit and even the abdominal cavity through the gas injection valve, and gas in the abdominal cavity is prevented from overflowing through filling. However, many gas injection valves configured in the existing puncture outfit have the phenomena of gas leakage, inconvenient operation and the like, and can not achieve good gas tightness and gas resistance; in addition, current puncture ware bottom lacks discharge valve, is difficult to the flue gas that quick discharge condensation sword produced, and discharge valve can't carry out altitude mixture control according to the depth of penetration moreover, uses the flexibility not good.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses an air injection valve for a puncture outfit and a puncture outfit [ CN201922392177.1] provided with the air injection valve, which comprises a puncture cannula arranged vertically, a sealing assembly arranged at the top of the puncture cannula, a puncture rod inserted vertically in the sealing assembly and the puncture cannula, and an air injection valve connected with the puncture cannula; the gas injection valve includes: the valve comprises a valve seat with a valve seat hole, a valve core rotatably inserted in the valve seat hole, an air inlet connecting pipe fixedly connected with the valve seat and communicated with the valve seat hole, and an air outlet connecting pipe fixedly connected with the valve seat and communicated with the valve seat hole; the air outlet connecting pipe is fixed with the puncture sleeve and communicated with the puncture sleeve, and a vent hole positioned in the valve seat hole is arranged on the valve core in a penetrating way; when the valve core rotates to a first working angle, the vent hole enables the air inlet connecting pipe and the air outlet connecting pipe to be communicated with each other; when the valve core rotates to a second working angle, the vent hole is isolated from the air inlet connecting pipe.

The scheme solves the problem of poor air tightness of a gas injection valve of the puncture outfit in the prior art to a certain extent, but the scheme still has a plurality of defects, such as: the bottom of the puncture outfit is lack of an exhaust valve, so that redundant gas is difficult to be rapidly exhausted, and the exhaust valve cannot be subjected to height adjustment according to the puncture depth, so that the use flexibility is poor.
