Technical Field
The utility model relates to the technical field of medical appliances, concretely relates to scope hemostatic clamp.
Background
The endoscope hemostatic clamp is a non-operative treatment hemostatic tool which is matched with the alimentary canal endoscope for use, is arranged in the endoscope and clamps a wound by using mechanical clamping action so as to realize hemostasis. Compared with surgical treatment, the hemostatic bag has the characteristics of minimally invasive, rapid hemostasis, low probability of rebleeding and complications, has an exact curative effect, has a good hemostatic effect on acute digestive tract hemorrhage, and is widely concerned by the medical field.
The hemostasis operation under the endoscope is an effective method, because the pathological changes can be seen, different hemostasis methods can be adopted according to specific conditions, wherein hemostasis by a hemostatic clamp is a common method. The principle is that the mechanical force of the clamp is utilized to clamp a tissue wound or a blood vessel to close the blood vessel, so as to play a role in stopping bleeding, and after several days, the wound is healed, and the clamping head falls off and is discharged out of the body along the digestive tract.
The mechanical hemostasis of the endoscope hemostatic clamp only causes minimal damage to mucous membranes around wounds, can directly clamp and close macroscopic hemorrhagic vessels and focus, and is particularly suitable for arteriole rupture hemorrhage.
Although the hemostatic clamp used under the endoscope commonly used in the market can clamp soft tissues at that time, the clamp can fall off due to insufficient force sometimes; the opening is not large enough, cannot rotate, causes clamping inconvenience, and the like.
