Description

Disposable stoma stricture dilatation catheter

Technical Field

The utility model belongs to the technical field of medical treatment auxiliary appliance, concretely relates to can not produce too strong pressure to the local intestines mucous membrane of expansion, avoid traditional expansion mode finger to put into too dark or excessive all kinds of injuries that cause, reduce secondary operation probability, the narrow expansion pipe of mouthful is made in disposable that the practicality is strong.

Background

Rectal cancer refers to cancer from the dentate line to the rectosigmoid junction, and is one of the most common malignancies of the digestive tract. Wherein, the middle and lower rectal cancer is close to the anal sphincter, the anus and the function thereof are difficult to be kept during the operation, and the abdomen is used as a permanent colostomy (commonly called as an artificial anus). However, the intestinal stoma stenosis is one of the common complications in the convalescence, and the main reasons are improper operation, poor blood circulation of the intestinal stoma, scar formation after separation and healing of the mucosal skin of the intestinal stoma, improper setting of the position of the intestinal stoma, or postoperative infection caused by contraction of the abdominal wall of the intestinal stoma; the secondary factors are colon distortion at the lower end of the enterostomy, fibrosis caused by tissue necrosis, and scar formation of the skin or muscle membrane pressed by tumor cell proliferation. Moreover, the patients show that the skin opening of the enterostomy is reduced and the mucous membrane is not seen, or the appearance is normal, but the enterostomy can be found to be in a tight or narrow shape during finger examination; patients with intestinal ostomy stenosis may develop symptoms and signs of stoma incompleteness obstruction.

At present, conservative therapy is generally adopted for patients with intestinal stoma stenosis, and the patients are instructed to take more cellulose-containing foods such as pawpaw, banana, citrus, sweet potato leaves and the like; meanwhile, the small finger is used for dilating the opening of the enterostomy twice a day, and the operation is required to be carried out for a long time, wherein the time is more than 10 minutes each time; if the condition is improved, the stoma can be dilated by the index finger. However, the actual situation is that the thickness of the fingers of the person is different, and the patient cannot be really and effectively helped to improve the stenosis symptom only by a simple propaganda and education way of 'little finger' or 'forefinger', but the danger of mucosal ulceration, bleeding, perforation and the like in the stoma is caused by improper operation. In addition, some clinical methods using a glass rod, a stainless steel rod and a silicon anal tube to expand the opening of the enterostomy can damage the mucous membrane of the enterostomy, cause the appearance deformation of the enterostomy, even cause perforation of the intestine and cause peritonitis, and have poor practicability. There is a need for improvements in the prior art stoma stricture dilation methods and devices.

Meanwhile, the lower end of the catheter tube body 1 is also provided with a catheter end closing head 10.

The upper part of a narrow expansion sacculus 7 arranged at the middle part of the catheter tube body 1 is provided with a fixed viscose base 6, and the fixed viscose base 6 is movably sleeved on the catheter tube body 1 by utilizing an opening at the middle part. The lower side of the fixed viscose base 6, which is connected with the skin of a patient, is provided with back adhesive paper, and the side part of the fixed viscose base 6 is provided with an easily torn convex edge 18; furthermore, the adhesive tape is used to prevent the adhesive base 6 from being accidentally touched before use, and the easy-to-tear convex edge 18 is used to facilitate the tearing off of the adhesive base 6. Moreover, the fixed viscose base 6 is of a circular structure, can be made of low-sensitivity medical viscose materials, has certain support performance and can prevent edge curling.

The upper side of the fixed viscose base 6 is fixedly provided with a catheter fixing clamp 5. The catheter fixing clamp 5 comprises two symmetrically arranged fixing clamp bodies 11, the middle parts of the two fixing clamp bodies 11 are connected through a connecting rotating shaft 12, and a clamping spring 16 for resetting and clamping the fixing clamp bodies 11 is further arranged between the middle parts of the two fixing clamp bodies 11. The rear end of each fixed clamp body 11 is provided with a clamping driving part 13, the front end of each fixed clamp body 11 is provided with a conduit clamping part 14, and the conduit clamping parts 14 at the front ends of the two fixed clamp bodies 11 enclose to form a conduit clamping cavity 15. The catheter securement clip 5 is connected to the upper side of the stationary adhesive base 6 by a base connection sleeve 17 disposed within the catheter retention chamber 15. Therefore, the two fixing clamps 11 are driven to open or clamp around the middle connecting rotating shaft 12 by the clamping driving part 13, so that the catheter fixing clamp 5 is connected with the catheter body 1 inserted in the base connecting sleeve 17 on the upper side of the fixed viscose base 6; and the catheter body 1 is effectively fixed by utilizing the adhesion surface of the lower side of the fixed viscose base 6 to be attached to the skin of a patient, so that the movement of the whole stoma stenosis dilatation catheter is avoided.
