Problems solved by technology

Laparoscopic suturing technique is one of the key points for the success of this operation. For some patients with severe bile duct wall inflammation and a bile duct wall thickness of more than 3mm, laparoscopic suturing is more difficult, and there is a very high postoperative bile leakage without suturing. Possibility, non-conventional suturing will lead to a variety of short-term and long-term accidents and complications after surgery, increasing patient pain and hospitalization costs
Having drainage tubes at two places on the body wall after the operation brings more inconvenience and pain to the patient. Multiple drainage tubes also increase the chance of tube detachment after the operation. Afterwards, the recovery is slow, and in the long run, the skin at the drainage site will be unsightly
[0004] To sum up, the existing patients with severe inflammation of the bile duct wall need intubation and drainage after the operation, and after the operation, two drainage tubes need to be placed on the body wall. After the operation, the two intubations on the body of the patient will affect each other , it will double the postoperative pain of the patient, and it will also increase the chance of tube detachment. In addition, after the postoperative drainage tube is issued, the inflammatory scars on the two parts of the patient's body where the drainage tube is placed are very obvious, resulting in a longer recovery period for the patient after surgery. Long, two drainage scars, in the long run, the skin of the drainage area will be unsightly, and it is very difficult to suture the bile duct wound, and the operation difficulty is very high

Abstract

The invention discloses a postoperative sutureless drainage device, and relates to the technical field of medical instruments. The postoperative sutureless drainage device comprises a drainage main tube, wherein the side wall of the drainage main tube is provided with an elastic structure soft rubber film, and the exterior of a fusiform blocking ring is coated with a square net. Due to the elasticstructure flexible rubber film, only one drainage main tube needs to be inserted into a patient after an operation, multiple problems caused by two intubation tubes can be effectively avoided, the number of intubation tube wounds is reduced, meanwhile, the probability of pipe detachment is reduced, and the patient recovery period can be effectively shortened due to only one intubation tube on thepatient body; the number of scars on the body is reduced after recovery, gel is formed when the carboxymethylcellulose net encounters water during an operation due to the square net, can be used foradhering and fixing an inner polyglycolic acid membrane to the broken position in the wall of the bile duct, and seal the gap between the inner polyglycolic acid membrane and the drainage main tube, so that no suture can be realized during operations, and the operation difficulty can be reduced; and occurrence of postoperative complications can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a postoperative suture-free drainage device. Background technique [0002] Clinical application Drainage system Drainage of fluid, digestive juice, excrement and pus is one of the main tasks of surgery. Surgical drainage is to export the above-mentioned liquid accumulated between human tissues or body cavities out of the body to control infection, promote wound healing, and reduce surgery. Post-complications, relief of discomfort caused by fluid mass effect. [0003] With the development of minimally invasive techniques, laparoscopic choledocholithotomy and T-tube drainage for the treatment of hepatolithiasis has become a routine procedure in hepatobiliary surgery. The bile duct wall was sutured, and the peritoneal drainage tube was placed on the wound to cooperate with drainage, so as to reduce and prevent postoperative complications. Laparoscopic suturing technique is...
