Description

Technical Field

[0001] The utility model relates to the technical field of endoscopic mucosal stripping surgery, in particular to an oral orthodontic rubber ring for traction. Background Art

[0002] Endoscopic submucosal dissection (ESD) refers to a minimally invasive technique that completely removes the diseased mucosa from the submucosal layer under an endoscope. It was first developed and applied clinically in Japan in the late 1990s. It is an elective diagnostic surgery or radical surgery. The main purpose of ESD is to diagnose and treat early gastrointestinal tumors. It has the advantage of completely removing a certain area of ​​superficial lesions at one time, but it requires high technical requirements and is difficult. During endoscopic submucosal dissection surgery, when the lesion is removed, it is usually necessary to traction the lesion to expose the field of view of the lesion. Orthodontic rubber bands have a good traction effect and are small in size, and can be better used for traction during endoscopic submucosal dissection surgery.

[0003] Generally, during endoscopic mucosal resection surgery, when pulling the lesion, it is necessary to first clamp one side of the orthodontic elastic band with a clamp, then directly enter the intestinal cavity from the clamp opening, then open the clamp to bite the elastic band and the anal end of the lesion, and then enter another clamp from the clamp opening again, clamp the other side of the elastic band, and then clamp it to the opposite side of the lesion to form effective traction. Since the clamp and orthodontic elastic band in the endoscopic mucosal resection surgery are both small in size, the operation is relatively troublesome when connecting the clamp and the orthodontic elastic band, which makes the time for connecting the hemostatic clamp and the orthodontic elastic band relatively long, thereby increasing the overall surgical operation time. Therefore, how to better save the time for connecting the hemostatic clamp and the oral orthodontic elastic band and reduce the overall surgical operation time is an important problem that needs to be solved in the design of oral orthodontic elastic bands for traction. Utility Model Content

The second fixing ring is fixedly connected to the side wall of the orthodontic elastic ring. The third connecting ring is sleeved on the side wall of the second fixing ring.

The third hemostatic clip and the fourth hemostatic clip can be clamped on the side wall of the intestinal cavity in turn for traction as the peeling proceeds, so that the peeled lesion can be better pulled during the operation, so that the peeling field of view is better.

[0038] The traction structure 2 includes a connecting ring 1 201, a fixing ring 1 202, a connecting ring 203 and a hemostatic clip 1 205. Four connecting rings 201 are sleeved on the side wall of the orthodontic elastic band 1, and the side walls of the four connecting rings 1 201 are all sleeved with a fixing ring 1 202. The side walls of the four fixing rings 1 202 are all sleeved with a connecting ring 2 203, and the side walls of the four connecting rings 203 are sleeved with a hemostatic clip 1 205.

[0041] Avoid sharp corners between the connecting ring 1 201 and the connecting ring 2 203 to avoid damage to the side wall of the intestinal cavity.

[0042] The hemostatic structure 3 includes a second fixing ring 301, a third connecting ring 302 and a second hemostatic clip 303. The second fixing ring 301 is fixedly connected to the side wall of the orthodontic elastic band 1. The third connecting ring 302 is sleeved on the side wall of the second fixing ring 301.
