Description

CARTILAGE HOLDING FORCEPS

TECHNICAL FIELD OF INVENTION

The present invention discloses a novel design of tissue holding forceps generally used in the medical surgery. Tissue forceps are used for grasping tissues during surgical operations which do not squeeze or crush soft tissue such as skin during use.

BACKGROUND ART

Tissue Forceps are devices used by doctors and medical practitioners to grip the soft tissue such as skin during surgery or other medical procedures. Traditionally, forceps have been available in a number of different type and designs like hemostatic forceps, tissue forceps, kelly forceps, and biopsy forceps. Conventional forceps have two grasping jaws at the top end thereof which can be plain or smooth, finely serrated so that they will not slip during grasping, or with interdigitating sharp elongated teeth. Such conventional forceps cause a considerable amount of crushing of tissues, leaving behind visible marks on the tissue.

The commonly known forceps design used by plastic surgeons is Adson-Brown forceps, with various modifications also. These forceps utilize opposing linear rows of fine teeth on each jaw of the forceps. In practice, such construction causes less trauma to tissue than the simple mouse tooth forceps or plain forceps with serrations.

However, conventional forceps have problems of slipping, crushing soft tissues; and do not have friendly design for easy and fast stitching during surgical operations. Accordingly, it is desired to provide an improved tissue forceps which not only avoid the crushing of tissue during use and support in stitching during surgery. SUMMARY

The present disclosure is about novel design and techniques applied in the medical surgery. This invention is an advanced design of Adson-Brown forceps tissue gripping forceps with novel design of jaw which is best suitable for medical surgery. The novel tissue holding forceps has first and second arms with two ends each i.e Head end and Rear end; and jaws at the Head ends of each arms of the forceps. The rear ends of two arms of the forceps are coupled together. The second ends, the head ends of the First and Second arms of the forceps form opposing First and second jaws which are resiliently biased apart. The First and second jaws each include a plurality of sharp, directly opposing rows of linear sharp elongated teeth to grip the tissue firmly during its use. The both jaws has a deep linear "CUT" in the center which makes jaw as " U" shaped. This novel design enable fast and easy surgical operations by reducing the time of operation by facilitating the stitching and other surgical operations.
