Hemostat

Abstract

The invention discloses a hemostatic clip, which comprises a clamping arm, the clamping arm includes a fixed clamping arm and a movable clamping arm; the number of the movable clamping arm is more than one; the tail end of the fixed clamping arm and the movable clamping arm The tail end of the arm is connected; the fixed clamping arm is matched with each movable clamping arm respectively to form more than one clamping unit; each movable clamping arm independently performs arc reciprocating movement relative to the fixed clamping arm to form a Independent opening and closing of the corresponding clamping unit. Since each clamping unit of the present invention can be opened and closed independently of each other, the wound can be treated by clamping one or several sides of the wound, then pulling it to the other side, and finally clamping the whole wound to complete hemostasis. This is not available in the prior art, which solves the problem of hemostasis for larger wounds and greatly facilitates the doctor's operation.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a hemostatic clip. Background technique [0002] At present, with the development of medical technology, endoscopy is not only used in disease diagnosis, but also in disease treatment, and whether the treatment effect is effective and reliable. Stomach, intestinal tract, nasal cavity and other tissues and organs of organisms often cause bleeding due to various diseases or accidents. Among them, the mechanical hemostasis of the hemostatic clip under the endoscope only causes minimal damage to the mucosa around the wound, and can directly clamp the bleeding blood vessels and lesions. It has been widely used in endoscopic treatment and is of great significance. [0003] However, the size of the wound treated by existing hemostatic clips is often limited by the length of the clamping arm of the hemostatic clip and the opening angle of the clamping arm, such as the hemostatic clip ...

AI Technical Summary

Problems solved by technology

[0003] However, the size of the wound treated by existing hemostatic clips is often limited by the length of the clamping arm of the hemostatic clip and the opening angle of the clamping arm, such as the hemostatic clip involved in the patent CN201410222753, see figure 1

Therefore, the treatment of large wounds cannot be satisfied

Even if changing to a hemostatic clip with a longer clamping arm and a larger opening angle meets the needs of dealing with large wounds, it will cause inconvenience to the doctor's operation, and even bring pain to the patient and cause further damage
