Instrument with resilient jaws

摘要

The teachings herein provide an instrument comprising a forceps. The forceps comprise a hand piece; a tubular member connected to the hand piece; and a jaw assembly connected to the hand piece. The jaw assembly includes a first jaw element and a second jaw element. The first jaw element includes a gripping section and a flexing section. The flexing section includes an arcuate section. The second jaw element opposes the first jaw element and includes a gripping section. The tubular member is moveable onto the arcuate section of the first jaw element so that the flexing section of the first jaw element is flexed and the jaw assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the jaw assembly is substantially rigid in the closed position.

1. An instrument comprising:
a forceps comprising:
i. a hand piece;ii. a tubular member connected to the hand piece; andiii. a jaw assembly connected to the hand piece, the jaw assembly comprising:
a. a first jaw element comprising a gripping section and a flexing section, the flexing section includes an arcuate section;b. a second jaw element opposing the first jaw element, the second jaw element comprises a gripping section; wherein the tubular member is moveable onto the arcuate section of the first jaw element so that the flexing section of the first jaw element is flexed and the jaw assembly is moved into a closed position, wherein the first jaw element and optionally the second jaw element includes a stiffening spine so that the jaw assembly is substantially rigid in the closed position, wherein in the closed position, an edge of the stiffening spine included on the first jaw element contacts the arcuate section of the first jaw element so that a uniform gripping pressure is provided along a gripping portion of the first jaw element and a gripping portion of the second jaw element, and wherein when the jaw assembly is in an open position, a gap is defined between the edge of the stiffening spine and the arcuate section of the first jaw element.
