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.

In order to improve the visual field environment of a doctor in the laparoscopic surgery, the applicant invents a gas circulation filtering device for the laparoscopic surgery, which comprises a gas pipe, a sealing bottle, a gas pump, a filter and a pressure release valve, wherein the gas pipe is sequentially provided with the sealing bottle, the gas pump, the filter and the pressure release valve from a gas inlet to a first gas outlet; when in use, the air inlet of the trachea and the first exhaust port are both required to be communicated to the abdominal cavity of a patient; in the prior art, an pneumoperitoneum needle is generally used to communicate with the abdominal cavity of a patient, the pneumoperitoneum needle itself is a single-channel part made of metal, and an air inlet and a first air outlet of an air pipe are required to be connected with the pneumoperitoneum needle and communicated with the abdominal cavity of the patient, so that the number of wounds of the patient is increased.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a dedicated suction head, utilize a part to realize the abdominal intake and the exhaust of disease, reduce the wound of laparoscopic surgery.

In order to solve the technical problem, the utility model discloses a technical scheme does: a suction head for a laparoscope gas circulation filter device comprises an inner tube and an outer tube, wherein the inner tube is inserted into the outer tube; for convenient production, the inner pipe and the outer pipe are suitable to keep coaxial position relation; the inner diameter of the outer pipe is larger than the outer diameter of the inner pipe, and a channel for gas to flow is formed between the outer pipe and the inner pipe; the length of the inner pipe is larger than that of the outer pipe, and both ends of the inner pipe exceed the outer pipe; the head end of the outer pipe is provided with a first exhaust port, and the tail end of the outer pipe is provided with an external interface; the outer interface of the outer pipe is used for being connected with a second exhaust port of an air pipe in the gas circulation filtering device, and the tail end of the inner pipe is used for being connected with an air inlet of the air pipe in the gas circulation filtering device.

Further, the inner tube is made of a metal material, and the outer tube is made of a plastic material.

Has the advantages that: the utility model discloses a attract head utilizes thick outer tube and thin inner tube to form two gas passage in attracting the head, cooperates gas circulation filter equipment to form the function of admitting air and giving vent to anger to the abdominal cavity of disease in laparoscopic surgery, reduces the wound of disease in laparoscopic surgery.
