Claim 1
Independent Claim
307 words
A disposable hemostat, comprising: a first and second handle member each of unitary construction and fabricated from a moldable, non-metallic material; each handle member having a generally elongated portion terminating at one end with an integral and manually graspable enclosed loop portion; each handle member being provided with a pivot portion integral with another end of said elongated portion; said pivot portion, said elongated portion and said loop portion of each handle member being generally coplanar in a first plane; each handle member being provided with an elongated nose portion having inwardly directed clamping teeth integral with said pivot portion and projecting from said pivot portion generally in a second plane parallel to but offset from said first plane; said first handle member having its pivot portion provided with an integrally molded hub; said second handle member being provided with an aperture in its pivot portion; said handle members being pivotally joined at their pivot portions with said hub being rotatably received through said second handle member aperture, and with said elongated offset nose portions being disposed in mutual coplanar relationship and pivotable about said pivot portions into mutual longitudinal clamping engagement; retaining means for said handle members comprising, a clip having an aperture therethrough and integral flange means encircling said clip aperture, said clip being slidably received over said hub with said hub freely received through said clip aperture and with said flange means being frictionally and slidably received over a substantial length of said hub; said flange means further encircling said hub with a portion of said flange means in frictionally locked engagement therewith, with said clip located in fixed position on said hub and overlying said second handle member pivot portion; and further wherein, said pivot portion, said elongated portion and said loop portion of each handle member are substantially equal in cross-sectional thickness.
