[0007] A further improvement of the technical solution of the utility model is that the traction mechanism includes an electric shaft rotatably connected to the four corners of one end of the traction tube, one end of the electric shaft is fixedly connected to a support rod, and one side of the outer wall of the support rod is fixedly connected to a silicone pad.

[0008] A further improvement of the technical solution of the utility model is that: a leakage hole is opened at one end of the outer wall of the pulling body, a plug hole is opened at one end of the pulling body away from the leakage hole, and a silicone protrusion is fixedly connected to the middle of the outer wall of the pulling body.

[0009] A further improvement of the technical solution of the utility model is that: one end of the traction tube away from the electric rotating shaft is threadedly connected to a sealing cover, and one end of the top of the inner wall of the sealing cover is fixedly connected to a sealing rubber ring.

[0010] A further improvement of the technical solution of the utility model is that a medical sponge is fixedly connected to the center of the top of the inner wall of the sealing cover, and the bottom of the medical sponge is plugged with the collagen thread and one end of the endoscope.

[0023] In this embodiment, the traction body 1 is inserted into the patient's body, and then one end of the traction tube 5 is inserted into the patient's wound to prevent air from entering the patient's body through the wound. A stabilizer 3 is provided on the inner wall of the traction tube 5, and an endoscope 4 is provided on the top of the stabilizer 3. After the traction tube 5 enters the patient's body, the position of the traction body 1 is adjusted using a hook 17 provided at one end of the endoscope 4 so that it wraps the stomach. At this time, the collagen lines 2 provided at both ends of the top of the traction body 1 are pulled so that the traction body 1 wraps the stomach and moves slowly toward the traction tube 5. When it moves to a suitable position, the traction mechanism is started, and the incision of the stomach is wrapped using the continuously opening and closing silicone pad 8. At the same time, the traction body 1 is pulled again to allow the stomach to continuously move in the traction tube 5.

[0030] Example 4

[0031] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, a groove 15 is opened at one end of the bottom of the endoscope 4, the inner wall of the groove 15 is fixedly connected to an electric telescopic rod 16, and the output end of the electric telescopic rod 16 is fixedly connected to a hook 17.

[0032] In this embodiment, a groove 15 is provided at one end of the bottom of the endoscope 4, and an electric telescopic rod 16 is provided on the inner wall of the groove 15. By starting the electric telescopic rod 16, a hook 17 provided at its output end is extended out of the endoscope 4, so as to prevent the hook 17 from accidentally damaging the patient's blood vessels when the endoscope 4 enters the patient's body.

[0033] The working principle of the retractor is described in detail below.

[0034] like Figure 1-4As shown, by inserting the traction body 1 into the patient's body, and then inserting one end of the traction tube 5 into the patient's wound, by setting a sealing cover 12 at the end of the traction tube 5 away from the electric rotating shaft 6, and setting a sealing rubber ring 13 at one end of the top of the inner wall of the sealing cover 12, the sealing cover 12 is tightened to prevent air from entering the patient's body along the traction tube 5, and by setting a medical sponge 14 at the center of the top of the inner wall of the sealing cover 12, the medical sponge 14 is used to wrap the outer wall of the collagen line 2 and the endoscope 4 to reduce the infiltration of air into the traction tube 5 through the gap, by setting a stabilizer 3 on the inner wall of the traction tube 5, and the endoscope 4 is set on the top of the stabilizer 3, when the traction tube 5 enters the patient's body, by setting a groove 15 at one end of the bottom of the endoscope 4, an electric telescopic rod 16 is set on the inner wall of the groove 15, and by starting the electric telescopic rod 16, the hook 17 set at its output end is extended out of the inner wall. The endoscope 4 is used to prevent the hook 17 from accidentally damaging the patient's blood vessels when the endoscope 4 enters the patient's body. The hook 17 is used to hook into the leakage hole 9 to pull the traction body 1 to wrap the stomach. The traction body 1 is fixed by inserting one end of the traction body 1 into the socket 10 opened at the end away from the leakage hole 9. Since a silicone protrusion 11 is provided in the middle of the outer wall of the traction body 1, the friction between the traction body 1 and the stomach is effectively increased. By providing an electric rotating shaft 6 at the four corners of one end of the traction tube 5, when the incision of the stomach is close to the traction tube 5, the electric rotating shaft 6 is started to drive the support rod 7 provided at one end. Through the opening and closing of the support rod 7, the silicone pad 8 provided on one side of the outer wall is fitted to the stomach. At the same time, the collagen line 2 is pulled again to pull the stomach into the traction tube 5, which solves the problem that the traditional traction device is difficult to align with the tube mouth when it is pulled to the tube mouth due to the different sizes of the stomach.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
