Description

Gas circulation filtering device for laparoscopic surgery

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a gas circulation filter equipment for laparoscopic surgery.

Background

Laparoscopic surgery refers to surgery performed with a laparoscope and its associated instruments: the specific operation is that a cold light source is used for providing illumination, a laparoscope lens (the diameter is 3-10mm) is inserted into the abdominal cavity, the digital camera shooting technology is used for leading the image shot by the laparoscope lens to be transmitted to a post-stage signal processing system through an optical fiber and displaying the image on a special monitor in real time; then, the doctor analyzes and judges the state of the patient through images of different angles of the patient organ displayed on the monitor screen, and performs the operation by using a special laparoscope instrument.

In laparoscopic surgery, in order to obtain a wide surgical space and a good visual field space, it is necessary to fill carbon dioxide gas into the abdominal cavity of a patient using a pneumoperitoneum machine so that the pressure in the abdominal cavity reaches about 1.9 Kpa. In the prior art, laparoscopic surgery has drawbacks: doctors using ultrasonic knives or other electrical energy devices tend to produce a large amount of smoke in the patient's abdominal cavity, which affects the field of view of the camera.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a gas circulation filter equipment, last filtration and the gas of purifying the patient abdominal cavity avoid smog to influence doctor's field of vision.

In order to solve the technical problem, the utility model discloses a technical scheme does: a gas circulation filtering device for laparoscopic surgery comprises a gas pipe, a sealing bottle, a gas pump and a filter;

the two ends of the air pipe are respectively called an air inlet and an air outlet, the air inlet and the air outlet are communicated to the abdominal cavity of a patient, and the air pipe is sequentially provided with a sealing bottle, an air pump and a filter from the air inlet to the air outlet;

the sealing bottle is a bottle with an empty inner part, the air pipe is disconnected at the sealing bottle, the two fractures are inserted into the sealing bottle, and the air pipe and the insertion hole of the sealing bottle are sealed; the particles of partial smoke and water mist particles which enter the back part of the sealed bottle from the gas in the abdominal cavity of the patient are adhered to the inner wall of the sealed bottle and are gathered downwards, so that the aim of removing the smoke is fulfilled; the air pump is used as a power source and is used for forming air circulation; the filter generally selects an air filtering membrane as a filter element, and directly adsorbs smoke in airflow.

Furthermore, a pressure release valve is arranged between the filter and the exhaust port, so that overlarge pressure in the abdominal cavity of the patient is prevented, and safety is guaranteed.

Furthermore, the air inlet and the air outlet are both provided with pneumoperitoneum needles, and the air inlet and the air outlet are communicated to the abdominal cavity of a patient through the pneumoperitoneum needles.

Has the advantages that: the utility model discloses a gas circulation filter equipment establishes the external circulation for the gas of patient's abdominal cavity in laparoscopic surgery, utilizes sealed bottle and filter to get rid of the diffuse smog in the patient abdominal cavity, has ensured the clear field of vision of laparoscopic lens, is favorable to the doctor to perform the operation.

Drawings

FIG. 1 is a schematic view showing the construction of a gas circulation filtering device for laparoscopic surgery according to embodiment 1.

Wherein: 1. an air tube; 101. an air inlet; 102. an exhaust port; 2. sealing the bottle; 3. an air pump; 4. a filter; 401. a housing; 402. an air filtration membrane; 5. and (4) releasing the valve.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example 1

As shown in fig. 1, the gas circulation filtering apparatus for laparoscopic surgery of the present embodiment includes a gas pipe 1, a sealed bottle 2, a gas pump 3, a filter 4 and a pressure release valve 5;

the length of the air pipe 1 is about two meters, and the inner diameter is 6 mm; two ends of the air pipe 1 are respectively called as an air inlet 101 and an air outlet 102, and the air pipe 1 is sequentially provided with a sealing bottle 2, an air pump 3, a filter 4 and a pressure release valve 5 from the air inlet 101 to the air outlet 102;

the sealed bottle 2 is a bottle with an empty interior, the air pipe 1 is disconnected at the sealed bottle 2, two fractures are inserted into the sealed bottle 2, and the air pipe 1 and the insertion hole of the sealed bottle 2 are sealed; partial smoke particles and water mist particles of the gas in the abdominal cavity of the patient enter the sealing bottle 2 and are adhered to the inner wall of the sealing bottle 2 and are gathered downwards, so that the aim of removing the smoke is fulfilled; the air pump 3 is used as a power source and is used for forming air circulation, and the circulation speed is generally 40L/min; the filter 4 comprises a shell 401 and an air filtering membrane 402 arranged in the shell 401, wherein the air filtering membrane 402 as a filter element directly adsorbs smoke in airflow; the pressure release valve 5 is automatically opened to release pressure after the pressure exceeds the set pressure, so that the excessive pressure in the abdominal cavity of the patient is prevented, and the safety is guaranteed.

When the gas circulation filter device of the present embodiment is applied, both the gas inlet 101 and the gas outlet 102 need to be communicated to the abdominal cavity of a patient; the air inlet 101 and the air outlet 102 may be provided with a pneumoperitoneum needle or other special suction head for convenient communication to the abdominal cavity of a patient.

Although the embodiments of the present invention have been described in the specification, these embodiments are only for the purpose of presentation and should not be construed as limiting the scope of the present invention. Various omissions, substitutions, and changes may be made without departing from the spirit and scope of the invention.
