Abstract
Abstract A surgical tool which includes a first elongated tubular member of flexible material and a second elongated member slidably mounted thereinside. Lengthwise extending circumferentially spaced slits are provided in a head end portion of the first elongated member dividing the head end portion into a plurality of jaws. A head on the second elongated member can be retracted between the jaws to cause the jaws to diverge. A resilient band surrounds portions of the jaws remote from the head end of the first elongated member so that when the head is further retracted until the head is inboard of a head end of the resilient band, the resilient band causes the jaws to close.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
A surgical tool which comprises an elongated tubular sheath of flexible material, an elongated member slidably mounted inside the sheath, there being lengthwise extending circumferentially spaced slits in a head end portion of the sheath extending from a head end of the sheath and dividing the head end portion into a plurality of jaws, a head on the elongated member having a thick portion of greater diameter than the inner diameter of the sheath so that, when the head of the elongated member is retracted between the jaws, the jaws are caused to diverge, and a resilient band surrounding portions of the jaws remote from the head end of the sheath so that, when the head is further retracted until the thick portion of the head is inboard of a head end of the resilient band, the resilient band causes the jaws to close.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
18 words
A surgical tool as in claim 1 wherein there are teeth on the interior faces of the jaws.
Claim 4
Dependent Claim
49 words
A surgical tool as in claim 1 wherein there are coupling members rotatably mounted on the sheath and on the elongated member and the coupling members are in threaded relation so that the elongated member is caused to advance along the sheath when the coupling members are relatively rotated.
Claim 5
Dependent Claim
45 words
A surgical tool as in claim 1 wherein the elongated member is tubular, there is a discharge opening in the head in communication with the hollow interior of the elongated member, and means is provided for projecting liquid along the interior of the elongated member.
