Description:
TECHNICAL FIELD OF INVENTION 
       [0001]    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 
       [0002]    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. 
         [0003]    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. 
         [0004]    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 
       [0005]    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 and Rear end; and jaws at the Heads of each arms of the forceps. The rear ends of two arms of the forceps are coupled together. The second ends, the head 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” shape. This novel design enable fast and easy surgical operations by reducing the time of operation by facilitating the stitching and other surgical operations.

The width of central cut  304  in the jaw&#39;s Tip  209  is indicated as  401  and linear depth of central cut is shown as  403 . 
         [0024]    The sharp elongated teeth in linear rows ( 301 A,  301 B) of jaws are designed in such a manner that are adjusted at the closing of jaws of the open ends/heads of first and second arm of the Cartilage or Tissue Holding Forceps. As shown in the  FIG. 5A-5B  where the enlarged illustration  500  of closed exemplary jaw is shown as  301  and arrangement of sharp elongated teeth at jaws of first arm  501 A and at the jaws of second arm  501 B of the exemplary Cartilage or Tissue Holding Forceps are shown as  500 . The size and shape of the teeth at jaw may vary as per requirement. Teeth can be sharp elongated, sharp fine alike teeth of file and linear elongated sharp rows. A jaw with fine teeth is shown in the  FIG. 5C  where the novel design of Forceps&#39; jaw with central cut  304  in the jaw&#39;s tip  209  is given with fine pyramidal shaped teeth  503  and central grove  302 , constructed in accordance with exemplary embodiments of the present disclosure. 
         [0025]    This novel design with central cut in the jaw&#39;s tip  209  enable new and efficient use of tissue/cartilage gripping forceps. As an illustration is shown in  FIG. 6A  that is a scenario of an exemplary application of present invention  601  (i.e Cartilage or Tissue Holding Forceps) during medical surgery. In this exemplary medical surgical operation the stitching of cartilage/skin  603  is shown where surgical needle  607  is efficiently held by the novel designed forceps  601 . The thread used for stitching is indicated as  605  and the required efficient grip of skin is achieved by means of right sized sharp elongated teeth  301  at jaws of the forceps. This is also further clearly shown in  FIG. 6B  which is an enlarged sectional view of jaws of Cartilage or Tissue Holding Forceps where the surgical needle  607  is held by novel Forceps  601  during medical surgery using thread  605 , where the application of the novel forceps is consistent with exemplary embodiments of the present disclosure. 
         [0026]    Another mode of present invention is shown in  FIG. 07  which is a perspective view of that is an Electro-Cartilage or Tissue Holding Forceps ( 700 ) constructed in accordance with exemplary embodiments of the present disclosure. This electro-Tissue Holding Forceps is designed for procedures requiring critically precise temperature control to reduce sticking and charring while coagulating. The novel forceps  700  has novel designed jaw  701  with central cut jaw&#39;s tip  209 , is connected with a holder  703  which is further connected to electric supply by electric wire  705 . 
         [0027]    The replacement design for Adson-Brown Tungsten Carbide Forceps with new technology is illustrated in  FIG. 08  which is a perspective view of another mode of present invention (Cartilage or Tissue Holding Forceps) constructed in accordance with exemplary embodiments of the present disclosure. The novel forceps  800  has novel designed jaw  801  with central cut jaw&#39;s tip  209 , where  803  and  805  are first and second arms of the novel designed forceps which are coupled together at point  807 . 
         [0028]    The substitution design for forceps with adjustable clamped for strength of grips is shown in  FIGS. 9A-B . Where the novel forceps  900  has novel designed jaw  901  with central cut jaw&#39;s tip  209 , where  903  and  905  are centrally hollow oval shaped rear ends of the first and the second arms of the novel designed forceps which are connected together at a pivot point  907  by respective midpoints  902  and  904  of the of the first and the second arms, respectively. For the adjustments of strength of grips, the triangle locks or levels  909 A and  909 B are used which are structurally arranged in opposite direction. For further clear disclosure in  FIG. 9B  the novel designed jaw  901  with central cut jaw&#39;s tip  209  with linear rows of sharp elongated teeth  902  is also shown. 
         [0029]    The present disclosed invention includes three major embodiments. First embodiment is the central cut  304  in the jaw tip  209  which can be of various sizes of width and depth. This central cut support in holding the surgical needle during surgical operation and support in the griping skin or tissue. This proper holding of surgical needle during stitching avoids slipping and repeated griping of the needle and accordingly, this save the effort and time of operation. 
         [0030]    Second embodiment is the use of variety of teeth like sharp elongated like spines, medium elongated in linear rows and fine but sharp tipped file like teeth. This required teeth shape and size is designed as per requirement of softness of tissue to be handled in the surgery. 
         [0031]    Third embodiment is the adaptation of feasible shape of the forceps with central cut jaw tip according to the user requirement. This shapes may include but not limit to similar to Adson-Brown tissue forceps, scissor like tungsten Carbide Adson-Brown tissue forceps and electro-Adson-Brown tissue forceps etc. 
         [0032]    The novel design can be made by using any tough and hard material including metals and alloys. The making material can be stainless steel, tungsten carbide, titanium, hard plastic or any other stainless metal.
