Embodiment Construction

[0024] Such as figure 1 As shown, a stepless hemostatic forceps of the present invention includes a first forceps handle 2 and a second forceps handle 1 hinged in the middle. The upper ends of the first clamp handle 2 and the second clamp handle 1 are provided with cooperating clamp heads to form a clamping part. The clamp heads have the same structure as the conventional hemostatic forceps and can be straight, arc or strip-shaped. figure 1 is not shown in . The lower ends of the first pliers handle 2 and the second pliers handle 1 are respectively provided with finger rings 15 and form an operating part. After the thumb and forefinger (or middle finger) are inserted into the two rings 15 respectively, the first pliers handle 2 and the first pliers handle are controlled by finger grip. The second clamp handle 1 is rotated to adjust the opening and closing degree of the clamping part and clamp the blood vessel and artery. A control device for controlling the clamping distance...

Abstract

The invention relates to the field of medical apparatuses for the general surgery department, in particular to stepless haemostatic forceps. The stepless haemostatic forceps comprise a first forceps handle and a second forceps handle of which the middles are hinged to each other, a control device used for controlling the clamping spacing of a clamping part is arranged in an operating part and comprises a slide rod connected to the first forceps handle, a fixed cover connected to the second forceps handle and a rotary cylinder rotatably arranged in the fixed cover, the end, deviating from the first forceps handle, of the slide rod slidably penetrates into the rotary cylinder, and slide keys which are distributed in the length direction of the slide rod and are in a helical line shape are arranged at the outer circumference of the slide rod; key grooves for being matched with the slide keys are formed in the inner circumference of the rotary cylinder so that the slide rod can drive the rotary cylinder to rotate through the cooperation of the slide keys and the key grooves when the slide rod moves in the direction of being close to or away from the second forceps handle and a lockingmechanism for locking rotation of the rotary cylinder is further arranged on the fixed cover. By means of the stepless haemostatic forceps, the injury to wound histocytes is avoided while the haemostatic effect is guaranteed, the stepless haemostatic forceps accord with operation habits of medical care personnel on conventional haemostatic forceps, and the quick locking and haemostatic function isachieved.

Description

technical field [0001] The invention relates to the field of general medical instruments, in particular to a stepless hemostatic forceps. Background technique [0002] Hemostatic forceps are widely used in various general surgery operations. Its principle is the same as that of a clip. In the process of rescuing patients, the hemostatic forceps clamps the large arteries to avoid massive bleeding. The structure of the hemostatic forceps is similar to that of ordinary pliers, both of which include a first pliers handle and a second pliers handle hinged in the middle, and one end of the first pliers handle and the second pliers handle is provided with cooperating pliers heads to form a clamping part. The other ends are respectively provided with finger rings and form an operation part. When in use, the thumb and index finger (or middle finger) are respectively inserted into the two rings, and the force exerted by the fingers makes the distance between the two clamp heads in th...
