Medical single-port laparoscope device

Abstract

The invention discloses a medical single-port laparoscope device, which belongs to the technical field of laparoscope medical equipment. The medical single-port laparoscope device comprises a main body, an annular cavity is arranged on the inner side wall of the main body, an air bag a and an air bag b are arranged in the cavity, and the outer side wall of the air bag a is fixedly connected with the inner side wall of the cavity, the inner side wall of the air bag b is fixedly connected with the inner side wall of the cavity, and the top of the body is fixedly connected with a connecting pipea and a connecting pipe b. In the present invention, a sliding block is adjusted to move in the cavity by inflating the air bag a and the air bag b, the sliding block moves to drive expansion pieces to move, and the four expansion pieces move to expand an incision, so that the laparoscopic surgery instrument can enter the abdomen of a patient through the interior of the expanded incision to perform an operation on the patient, during the operation, the expansion pieces will not be squeezed out of an incision by the laparoscopic surgical instrument, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of laparoscopic medical equipment, in particular to a medical single-hole laparoscope device. Background technique [0002] Single-port laparoscopic surgery refers to making a small incision through the abdomen, and the size of the incision is usually 0.5-1.5 cm, so it is also called minimally invasive surgery. [0003] When performing single-port laparoscopic surgery, it is necessary to use relevant medical instruments and use special devices to support the incision in order to facilitate the operation. However, the currently used incision support devices are basically composed of the support device. It can be made into a structure that can be disassembled, and the wound can be fixed. The fixation is cumbersome, and it is easy to support and damage the abdominal tissue structure, which is not conducive to the recovery of the incision in the later stage.

Problems solved by technology

[0005] However, during the use of this device, carbon dioxide is injected into the abdomen, and air is also injected into the air bag during the infusion. When the air bag expands and the incision is fixed, one of the air valve switches is closed to stop the air bag. Gas perfusion keeps the airbag in a consistent state of expanding the incision, which is convenient for doctors to perform single-port laparoscopic surgery. However, since the expansion incision is opened by the method of balloon expansion, the expansion incision can only be fully filled by the airbag. The laparoscopic surgical instrument also needs to be inserted into the patient's abdomen through the incision. During the operation, the air bag is easily squeezed out from the incision by the laparoscopic surgical instrument, and the incision cannot be expanded. Laparoscopic surgical instruments require a certain amount of room for movement during operation, and the size of the airbag is difficult to be squeezed and changed, resulting in tearing of the incision and causing damage to the patient's body

In addition, the size of the airbag cannot be adjusted according to actual needs, which has high limitations
