Description

Surgical operating forceps

Technical Field

The invention relates to the field of medical instruments, in particular to a pair of surgical operating forceps.

Background

Various surgical instruments are often used in surgical operations, such as scalpels, surgical scissors, surgical forceps, tweezers, etc., wherein the surgical forceps are widely used, and are lighter than vascular forceps in squeezing tissues, so that the surgical forceps are generally used for clamping soft tissues and preventing the soft tissues from slipping off, for example, clamping and drawing the excised lesion part to facilitate the operation, clamping gauze pads and subcutaneous tissues at the edges of incisions, and avoiding the tissues in the incisions from being polluted, etc.

The operation time is usually longer, especially for major operations, if the opening degree of the forceps is always controlled by two hands, a doctor is tired, so that the doctor is helped by connecting an elastic part on the forceps arms in the prior art. For example, in CN105496509A, the medical forceps is more flexible and convenient by installing a labor-saving spring 1-1 between two forceps handles, which is shown in figure 1 (a). Also, CN208081269U, in which the surgeon is assisted by installing a fixed spring rod 1-2 between the upper and lower handles, see FIG. 1 (b).
