Description

Tissue forceps for hand surgery

Technical Field

The utility model relates to a surgical auxiliary instrument correlation technique, in particular to a tissue forceps for hand surgery.

Background

The tissue forceps are also called as mouse tooth forceps and Allis forceps (Allis) and are used for pressing and clamping tissues to keep the tissues from slipping, such as clamping and drawing a cut lesion part to facilitate operation, and clamping gauze pads and subcutaneous tissues at the edges of incisions to avoid the tissues in the incisions from being polluted. However, the number of muscles in hand surgery is large, and especially the formation of the aponeurosis of the dorsal digital is complex, where the outer tendon, the lateral tendon and the central tendon are involved in finger deformity or trauma.

The alice type tissue forceps have the advantages of being undoubtedly superior, but have some defects in different use environments, and have the following points:

the meshing port is single: for example, the clamping of the tendon tissue on the outer side of a finger, because the tendon tissue can extend to the joint between the fingers and the outer side of the finger forms close fiber connection, tissue clamps with different meshing surfaces are often needed in the clamping process; however, the traditional tissue forceps have a single jaw shape, and the jaws cannot be adjusted, for example, a single tooth can clamp fine fibrous tissues, a plurality of teeth can clamp tissues with a large cross section, and the forceps need to be replaced frequently, which causes unsmooth operation or needs to add hands.

No illumination: when in trauma or field emergency, such as clamping and suturing, the traditional tissue forceps have no illumination function in the use process under the condition of poor light, and have no interface carried by an illumination lamp, such as poor illumination at night, subcutaneous tissues are difficult to see clearly, errors are easy to judge, and hand nerves or muscle tissues are injured by mistake.

The following steps are required: in the process of clamping peripheral tissues such as tendon bundles, flexor tendon sheaths and the like, the traditional tissue forceps are easily interfered by fat, damaged skin or other unrelated tissues, the clamping accuracy is affected, sometimes, a forceps body or a pressing plate needs to be used for pulling out other unrelated tissues in a matched mode, the other hand is needed for matching, but the other hand may hold a scalpel or a hemostatic forceps and the like, and the burden is increased.
