Description

Surgical forceps

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to surgical forceps.

Background

Forceps are one of the most commonly used surgical instruments for grasping and lifting tissue to facilitate dissection and suturing. The forceps have different lengths and are divided into two kinds of toothed forceps and non-toothed forceps, the toothed forceps are called surgical forceps or skin forceps, the sharp ends of the forceps are toothed, the teeth are divided into coarse teeth and fine teeth, the coarse teeth forceps are used for clamping harder tissues, the injury is large, and the fine teeth forceps are used for fine operations, such as tendon suture, plastic surgery and the like. The tip has hook teeth, so the clamping is firm, but certain damage is caused to tissues. The toothless forceps are called flat forceps or dressing forceps, tissue forceps, and the tip of the toothless forceps has no hook teeth and is used for clamping fragile tissues, viscera and dressings. Short forceps are used for superficial operation, long forceps are used for deep operation, and the sharp-pointed flat forceps are less harmful to tissues and are used for vascular and nerve operations.

The traditional surgical forceps are convenient to operate, but are labor-consuming in tissue clamping, and particularly, when deep tissues are clamped by lifting, the phenomena of tiger's mouth ache and the like easily occur. And the traditional surgical forceps require a larger hand force to generate a clamping force at the tip of the forceps due to the fact that the pivot is closer to the holding position. In addition, the handle is not suitable for the tiger's mouth, which causes more labor to be consumed.

The second connecting structure comprises a connecting shaft 6 arranged at the rear end part of the holding end male end 201 and a connecting ring arranged at the rear end part of the holding end female end 202; compared with the first connecting structure, the connecting ring 7 of the second connecting structure is sleeved outside the connecting shaft 6 and can move along the connecting shaft 6 in the circumferential direction. Third connection structure include parallel arrangement's first notch and second notch, the centre of first notch and second notch all is provided with notch 203, third connection structure still includes boss 105, and the vertical setting of boss 105 can be followed the length direction slip of notch 203 in notch 203.

Taking the structure formed by connecting the holding end male end 201 and the clamping end male end through the third connecting structure as an example, as shown in fig. 4, a first slot piece and a second slot piece are arranged at the front end of the holding end male end 201, the first slot piece is flush with the upper surface of the holding end male end 201, and the second slot piece is flush with the lower surface of the holding end male end 201. The middle of the first slot piece and the second slot piece is provided with the same notch (203) along the vertical direction. The rear end of the first forceps handle 101 is provided with a boss 105, and the rear end of the first forceps handle 101 is clamped between the first slot piece and the second slot piece, so that the boss 105 located on the upper surface and the lower surface of the rear end of the first forceps handle 101 is vertically arranged in the notches 203 of the corresponding first slot piece and the second slot piece, and the up-and-down displacement of the first forceps handle 101 is limited. The boss 105 can slide in the slot 203 along the length direction of the slot 203, and the length direction of the slot 203 is consistent with the length direction of the male end 201 of the holding end, so that the clamping and the opening of the clamping end 1 are realized.

The surgical forceps in this embodiment has a bilateral symmetry structure, and the connection structure formed by the male end 201 of the clamping end and the male end 201 of the holding end and the connection structure formed by the female end 202 of the clamping end and the female end of the holding end are symmetrically arranged on two sides of the fixing rod 3. Therefore, the third connecting structure for connecting the front end part of the holding end female end 202 and the rear end part of the second forceps handle 103 is the same as the third connecting structure for connecting the holding end male end and the holding end male end 201.

The outer side surfaces of the holding end male end 201 and the holding end female end 202, which are far away from the fixing rod 3, are provided with the convex structures 204 which are special-shaped convex structures, so that the holding comfort degree can be improved when the holding end male end 201 and the holding end female end 202 are in contact with the palm.

The fixing rod 3 in this embodiment is disposed between the first connecting structure and the second connecting structure, the end heads 301 disposed at two ends of the fixing rod 3 are fixedly connected to the extending end of the connecting shaft 6 of the first connecting structure and the extending end of the connecting shaft 6 of the second connecting structure, respectively, and the end heads 301 are located above the connecting rings 7. The fixed rod 3 is used for fixing the axial center distance between the first connecting structure and the second connecting structure; the tip 301 serves to fix the position of the fixing rod 3 and to restrict the axial displacement of the connection ring 7 by being disposed above the connection ring 7.

The elastic component in this embodiment is a cylindrical spring 4, the cylindrical spring 4 is symmetrically arranged on two sides of the fixing rod 3 in pairs, and is connected with the fixing rod 3 and the first forceps handle 101, the second forceps handle 103 through hooks 401 arranged on the fixing rod 3 and the first forceps handle 101, the second forceps handle 103 respectively.

When the surgical forceps are used, the first forceps handle 101 and the second forceps handle 103 of the clamping end 1 are pressed by fingers, the boss 105 of the third connecting structure is driven to move in the strip-shaped through hole of the notch 203, and the connecting ring 7 of the first connecting structure and the second connecting structure moves circumferentially along the connecting shaft 6, so that the female end of the clamping end and the male end of the clamping end move relatively, the female end 202 of the holding end and the male end 201 of the holding end move relatively, clamping actions of the surgical forceps are achieved, and objects to be clamped are clamped by the first forceps head 102 and the second forceps head 104. When the object to be clamped needs to be released, the force of the fingers is released, the female end of the clamping end and the male end of the clamping end move in opposite directions only through the restoring force of the elastic structure, and the female end 202 of the holding end and the male end 201 of the holding end move in opposite directions, so that the opening action of the surgical forceps is realized.
