The technical scheme further comprises the following steps: the buckle is connected with the notch in a buckle mode.

The check valve comprises a valve body, a plurality of valve clacks are arranged in the valve body, the valve body is led to the columnar channel, the valve clacks are recessed inwards to form cambered surfaces, adjacent valve clacks are mutually abutted and expanded, the check valve is used for sealing the columnar channel, surgical instruments can be inserted into the check valve to operate, and gas in the sealing body cannot overflow the check valve.

The sealing body is in a round table shape, the sealing body is arranged to be sealed at the upper end and open at the lower end, and when the incision is required to be opened, the sealing body is turned inwards or outwards, so that the sealing body continuously rotates to enter the expander until the expander cannot be turned, the expansion degree of the expander reaches the maximum, and at the moment, the incision is protected, and the incision is fully retracted and expanded.

The protective film is arranged at the bottom of the elastic application, when the expander fully expands the wound, medical staff tears the protective film off again, and the elastic application is attached to the skin of a patient, so that the combination stability of the laparoscopic surgery incision retracting fixer and the human body is ensured.

Compared with the prior art, the utility model has the beneficial effects that:

1. according to the utility model, the size of the laparoscopic surgery incision fixer can be adjusted by matching the buckle on the first arc-shaped plate and the notch on the second arc-shaped plate in the expander, so that the surgery incision fixer can be suitable for wounds with different sizes.

2. According to the utility model, after the incision is cut on the abdomen of a patient, the incision is opened through the expander, the incision size is stabilized, and the operation of surgical instruments, the implantation of a laparoscope and the like can be simultaneously carried out through the channels of the plurality of one-way valves on the upper end surface of the sealing body, so that the condition that the surgical instruments enter the cavity through a single operation channel to cause interference, friction or collision to each other, influence the operation or cause abrasion and damage to the surgical instruments is avoided.

Detailed Description

The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.

Example 1

As shown in fig. 1-4, the incision retractor for laparoscopic surgery provided by the utility model comprises an expander 1 and a sealing body 7, wherein the expander 1 comprises an arc plate 2, a first arc plate 3 is arranged at one end of the arc plate 2, a second arc plate 4 is arranged at one end of the arc plate 2 far away from the first arc plate 3, a buckle 5 is rotationally connected to the first arc plate 3, a plurality of notches 6 matched with the buckle 5 are formed in the second arc plate 4, an elastic application 8 is matched with the surface of the sealing body 7, a plurality of columnar channels 9 are formed at the upper end of the sealing body 7, and a one-way valve 10 is arranged outside the columnar channels 9; the buckle 5 is in buckle connection with the notch 6; the arc-shaped plate 2, the first arc-shaped plate 3, the second arc-shaped plate 4 and the elastic application 8 are all made of medical transparent elastic materials; the sealing body 7 is provided with a truncated cone shape with an upper end sealed and a lower end opened; the bottom of the elastic application 8 is provided with a protective film 13.
