Hemostatic device under endoscope

Technical Field

The invention relates to the technical field of medical instruments, in particular to a hemostatic device under an endoscope.

Background

With the gradual popularization and spread of the digestive endoscope technology, more and more digestive tract diseases originally belonging to surgical treatment are converted into minimally invasive treatment under the digestive endoscope at present. The hemorrhage of the digestive tract is a difficult problem after the operation before the digestive endoscope. Digestive bleeding can occur in the upper digestive tract (esophagus, stomach or small intestine) or in the lower digestive tract (colon and rectum). Causes of gastrointestinal bleeding include gastric ulcers, arterial or venous (arteriovenous) malformations, cancer, or inflammatory bowel disease, among others. Elderly patients also have a high risk of death from severe gastrointestinal bleeding.

At present, under a digestive endoscope, hemostasis treatment mainly depends on heat effect, mechanical effect (high-frequency electrotome, hemostatic clamp and suture), chemical component hemostatic or injection medicine and the like for hemostasis. The above hemostatic treatment methods all have risks of damaging surrounding tissues and rebleeding, and simultaneously require precise placement of instruments on the surface of bleeding blood vessels through an endoscope to achieve hemostatic effect, and at the same time, there is no quick and effective means for treating hemostasis by diffuse bleeding of tiny arteriovenous under a digestive endoscope.

Most of the absorbable hemostatic products which are circulated in the market at present are applied to the field of surgical operations, and comprise plant hemostatic agents (microporous polymers) suitable for hemostasis in the alimentary canal, and no effective means is provided for the products to be placed at bleeding and bleeding points in the alimentary canal through a digestive endoscope at present, so that the absorbable hemostatic products, whether powder or fluid, are very easy to block the endoscope pipeline and damage the lens, and the operation visual field is influenced.

Accordingly, there is a need to develop an endoscopic hemostatic device by which an absorbable hemostatic product (in powder or fluid form) can be safely and effectively delivered to the site of bleeding or ulceration.

The spiral channel container is designed according to the aerodynamic principle, can greatly reduce the resistance surface and quickly convey hemostatic materials into the catheter. Preferably, the helical groove is clockwise rotated.

Preferably, a rotary valve switch is provided between the injection port and the spiral passage container to open and close the passage.

Preferably, a conduit is connected to the ejection opening.

More preferably, the conduit is made of PVC material, and has an outer diameter of 2.0-3.0 mm, an inner diameter of 1.8-2.8 mm and a length of 2 m.

Preferably, the hemostatic material is a powder or fluid hemostatic product.

Compared with the prior art, the invention has the following beneficial effects:

the invention is used for assisting a mechanical hemostasis means to treat the alimentary tract hemorrhage, can quickly achieve the hemostasis effect on tiny arteriovenous and diffuse blood seepage, and can achieve the effects of stopping bleeding and promoting healing on alimentary tract inflammation, ulcer wound surfaces and tiny bleeding points.

The invention has simple operation, convenient use, safety and reliability, and can prevent pollution at one time.

The invention fully solves the problem that the absorbable hemostatic product cannot be used for wound hemostasis in the prior endoscopic descending alimentary canal treatment and operation. The invention uniformly conveys the hemostatic products to bleeding, bleeding points and ulcer surfaces through the endoscope instrument pipeline by air pressure, thereby achieving the ideal hemostatic effect and effectively reducing the risk of re-bleeding caused by gastrointestinal peristalsis caused by tube drawing after operation; and provides an environment for drying the wound surface, and promotes the rapid healing of the patient after the operation.
