Straight-head haemostatic forceps

Abstract

The invention relates to a pair of straight-head haemostatic forceps. The straight-head haemostatic forceps comprise a left forceps body and a right forceps body which are connected with each other in a hinged mode. The front end of the left forceps body and the front end of the right forceps body are of corrugated occlusal surfaces with the smooth-transition edges, and the front end outer wall of the left forceps body and the front end outer wall of the right forceps body are of a smooth-transition arc surface. The straight-head haemostatic forceps are made of high polymer materials and formed in a mold-typed injection molding mode, hinge of the left forceps body and the right forceps body is achieved through match of a pin shaft and a pin hole, installation is simple and convenient, and the degree of tightness is appropriate as well. Further more, the smooth-transition edges of the occlusal surfaces of the straight-head haemostatic forceps are adopted, so that shearing injury to the tissue or blood vessels will not occur when the straight-head haemostatic forceps are used for clamping the tissue or blood vessels. A locking rack of the straight-head haemostatic forceps is provided with three tooth buckles, thus, three kinds of locking degrees are achieved, and the appropriate locking degree can be chosen according the required clamping amount of the tissue or blood vessels.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a straight-head hemostatic forceps. Background technique [0002] Straight-head hemostats are used for superficial hemostasis and tissue separation at the surgical site, while toothed hemostats are mainly used for hemostasis of tough tissues and lifting the incision. [0003] The existing straight hemostatic forceps are usually made of metal materials, assembled by two pieces of forceps, the two pieces of forceps are hinged by screws, and the rear inner sides of the two pieces of forceps 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 ...

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 straight hemostat is mainly used to keep the straight hemostat in a locked state. The locking rack of the straight 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, straight hemostats with only one degree of locking often cannot be clamped in place
