Description

Hemostatic material laying forceps for endoscopic surgery

Technical Field

The utility model relates to a hemostatic material laying clamp for endoscopic surgery.

Background

The endoscopic surgery is one of surgical minimally invasive surgery, and mainly comprises laparoscopic surgery, thoracoscopic surgery, hysteroscopic surgery, arthroscopic surgery and the like, wherein the endoscopic surgery achieves the effect of traditional open surgery, such as tumor excision, reconstruction after excision and the like. The wound surface is subjected to the endoscopic surgery, and the wound surface is subjected to blood seepage after the operation due to factors such as cut-off of capillaries and poor coagulation function of a patient, so that a hemostatic material is usually placed on the wound surface after the endoscopic surgery, the commonly used hemostatic material comprises hemostatic gel, hemostatic powder and solid hemostatic materials (hemostatic sponge and the like), the hemostatic gel and the hemostatic powder are directly sprayed on the wound surface, the solid hemostatic materials are placed in a body through a endoscopic stamping card and then are paved by using endoscopic forceps, and good hemostatic effect can be exerted after the hemostatic materials are paved at a proper position. For example, the reconstruction operation (such as blood vessel, bile duct, intestinal canal, etc.) of the pipeline needs to be laid around the anastomotic stoma of the pipeline, and for the operation (such as the excision of liver part, excision of retroperitoneal tumor, etc.) with only wound surfaces, curved surface laying is needed, the materials of the solid hemostatic material are usually collagen, regenerated oxidized cellulose, etc., and the hemostatic material is easy to deform after being stained with the aqueous solution in the body cavity, so that the hemostatic material is laid and formed as once as possible during laying, and the change of the position due to repeated lifting is avoided.
