Curved haemostatic forceps

Abstract

The invention relates to a pair of curved haemostatic forceps. The pair of curved haemostatic forceps comprises a left forceps body and a right forceps body, wherein the left forceps body and the right forceps body are made of high polymer materials and hinged to each other, the front end of the left forceps body and the front end of the right forceps body are respectively a corrugated engagement face, the edge of each engagement face is in smooth transition, and the outer wall of the front end of the left forceps body and the outer wall of the front end of the right forceps body are respectively a cambered surface in smooth transition. The pair of curved haemostatic forceps is made of high polymer materials in a mold injection molding mode, the two forceps bodies are hinged through cooperation between a hinge pin and a pin hole, and the pair of curved haemostatic forceps is easy and convenient to install and appropriate in elasticity; in addition, the edges of the engagement faces of the pair of curved haemostatic forceps are in smooth transition, when the pair of curved haemostatic forceps is used for clamping tissue or a blood vessel, the pair of haemostatic forceps will not cause shearing injuries to the tissue or the blood vessel. A locking rack of the pair of curved haemostatic forceps is provided with three buckling teeth, three locking degrees are achieved, and the appropriate locking degree can be selected according to the amount of the tissue needing to be clamped or the diameter of the blood vessel needing to be clamped.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an elbow hemostat. Background technique [0002] Elbow hemostats are used for deep hemostasis and tissue separation at the surgical site, and toothed hemostats are mainly used for hemostasis of tough tissues and lifting the incision. [0003] The existing elbow hemostatic forceps are usually made of metal materials, and are assembled by two pieces of forceps bodies, which are hinged by screws, and the rear inner sides of the two pieces of forceps bodies are provided with locking teeth that cooperate with each other strip. When hinged by screws, it is difficult to grasp the degree of tightness of the screws, resulting in the existing hemostatic forceps being too loose or too tight when used. In addition, when the tissue or blood vessel is clamped, the edge of the occlusal surface is relatively sharp, which may cause shear damage to the tissue or blood vessel. The lo...

AI Technical Summary

Problems solved by technology

When hinged by screws, the degree of tightness of the screws is difficult to grasp, resulting in the existing hemostatic forceps being too loose or too tight when used

In addition, when the tissue or blood vessel is clamped, the edge of the occlusal surface is relatively sharp, which will cause shear damage to the tissue or blood vessel

The locking rack of the elbow hemostat is mainly used to keep the elbow hemostat in a locked state. The locking rack of the elbow hemostat currently used is usually a snap-in structure with only one degree of locking. When in use, because there are more or less tissues or blood vessels to be clamped, the elbow hemostat with only one degree of locking often cannot be clamped in place
