Problems solved by technology

However, although the existing drainage device avoids the physical injury of the second operation, all the hard parts are exposed outside the body through the anus, which greatly reduces the quality of life of the patient during the postoperative recovery period, and some patients cannot bear it. A case of anal foreign body being removed ahead of time, leading to anastomotic infection

Embodiment Construction

[0025] Such as Figure 1 to Figure 7 Shown is the degradable intestinal support for rectal anastomosis protection in this embodiment, which is composed of intestinal degradable support 1 , degradable suture 2 , and anastomotic protective sleeves 3 and 4 . The intestinal degradable support 1 is a magnesium-zinc alloy wire with a diameter of 0.5 mm, which is made into a round tube mesh support by weaving, such as figure 1 , figure 2 shown. In order to effectively prevent excrement from leaking to the anastomosis, the anastomotic protective sleeve 3 is fixed on the upper end of the support and passes through the support; the anastomotic protective sleeve 4 is fixed on the lower end of the support, covering the anastomotic along the intestinal tract, Such as figure 1 , image 3 shown. This structural design can provide double-layer protection, so that when a small amount of excrement seeps out from the edge of the upper protective cover, the lower protective cover still prov...

Abstract

The invention provides a degradable intestinal stent for rectal anastomosis protection, in particular to the field of medical instruments, the degradable intestinal stent includes an intestinal degradable support member, anastomotic protection sleeves with two open ends, a fixed support member and a protective sleeve degradable suture; in a service state, the stent is placed 5 to 10 cm at the front end of the anastomosis, and is completely placed in the rectum, and no hard parts are exposed to the outside of the body through the anus, the degradable support member applies a circumferential supporting force to the inner wall of the intestinal tract to closely adhere to the intestinal tract, and the two protective sleeves are closely attached to the intestinal wall at the fixed portion and completely cover the anastomosis. The stent can not only avoid the injury of the second surgery, but also does not affect the quality of life of the patient after surgery.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a degradable intestinal support for rectal anastomosis protection. Background technique [0002] Rectal cancer is one of the common malignant tumors. At present, resection is the main treatment. However, there are complications of anastomotic infection after operation, so it is necessary to protect the anastomotic. [0003] The traditional protective measures are to make a temporary enterostomy on the abdominal wall of the human body, cut off the colon connected with the esophagus and stomach, fix the broken end on the abdominal wall to form an enterostomy, and perform a second operation after the anastomotic stoma is healed , Return the intestines. Although this traditional method effectively reduces the incidence of complications, it increases the physical burden and medical expenses of patients. At present, there are a variety of drainage devices used to protect th...
