Abstract
Abstract Surgical forceps for use and association with a catheter for gaining access to a body cavity so as to release fluid therefrom. The forceps include handle means which preferably are finger loops attached to a pair of elongate members pivotally attached to each other at a common intersection point. There also is provided a pair of opposed gripping or cutting jaws which substantially are located at adjacent ends of the pair of elongate members which are each remote from the finger loops. There is also provided at least a partially tubular retaining passage to facilitate the insertion therefrom and retention therein of a catheter or catheter support. Preferably the retaining passage comprises opposed projections on each elongate member adjacent a respective gripping jaw which are channel like in shape so that when the forceps are in at least a partially closed position the retaining passage is formed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
197 words
Surgical forceps for use in association with a catheter for gaining access to a body cavity so as to drain fluid therefrom, said forceps including: (i) a pair of elongate members pivotally attached to each other at a common intersection point thereby providing one set of mutually adjacent ends comprising finger loops and another set of mutually adjacent ends comprising a pair of opposed blunt dissection jaws for flunt dissection of tissue blocking access to said body cavity, said blunt dissection jaws each having a free end and said free ends abutting in an operational position thereof to facilitate said blunt dissection of said tissue; said common intersection point being located nearer the blunt dissection jaws than said finger loops and said elongate members forming said blunt dissection jaws initially diverging from each other adjacent the common intersection point and subsequently converging to form said free ends; and (ii) a retaining passage formed by opposed channel shaped projections on each elongate member, each channel shaped projection being spaced from and located rearwardly of the free end of the blunt dissection jaw of the associated elongate member and projecting outwardly from the plane of the blunt dissection jaws.
Claim 2
Dependent Claim
197 words
Surgical forceps for use in association with a catheter for gaining access to a body cavity so as to drain fluid therefrom, said forceps including: (i) a pair of elongate members pivotally attached to each other at a common intersection point thereby providing one set of mutually adjacent ends comprising finger loops and another set of mutually adjacent ends comprising a pair of opposed blunt dissection jaws for flunt dissection of tissue blocking access to said body cavity, said blunt dissection jaws each having a free end and said free ends abutting in an operational position thereof to facilitate said blunt dissection of said tissue; said common intersection point being located nearer the blunt dissection jaws than said finger loops and said elongate members forming said blunt dissection jaws initially diverging from each other adjacent the common intersection point and subsequently converging to form said free ends; and (ii) a retaining passage formed by opposed channel shaped projections on each elongate member, each channel shaped projection being spaced from and located rearwardly of the free end of the blunt dissection jaw of the associated elongate member and projecting outwardly from the plane of the blunt dissection jaws.
Claim 3
Dependent Claim
29 words
Surgical forceps as claimed in claim 1 wherein said dissection jaws are provided with opposed inner surfaces of a corrugated nature to thereby define a plurality of gripping ribs.
Claim 4
Dependent Claim
99 words
Surgical forceps as claimed in claim 1 comprising pivotal attachment means for said pair of elongate members comprising a box joint wherein one elongate member is provided with a web having opposed recesses which is interposed between mutually opposed planar parts of the other elongate member whereby in use in an opened out position the web of said one elongate member extends at an angle to the planar parts of the other elongate member and in the closed position the opposed planar parts of the other elongate member are accommodated within the confines of each recess of the web.
