Abstract
Abstract A surgical pin driver having a pair of elongated clamping jaws terminating in a clamping handle is provided with a bearing member pivotally movable relative to the clamping jaws for engagement therewith to move the clamping jaws from an open position to a closed position and vice versa. A bridging member surrounds the clamping jaws and is pivotally attached to the bearing member. An actuating lever having an actuating handle is bifurcated at the end remote from the actuating handle so as to provide a gap which encloses the clamping jaws. The bearing member is formed as an extension of the actuating lever so that the clamping handle and the actuating handle are capable of being gripped in one hand for driving a pin clamped between the clamping jaws into bone.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
139 words
A surgical pin driver comprising a pair of elongate clamping jaws terminating in a clamping handle; a bearing member pivotally movable relative to said clamping jaws for engagement therewith to move said clamping jaws from an open position to a closed position and vice versa; a bridging member surrounding said clamping jaws wherein said bearing member is pivotally attached thereto; an actuating lever having an actuating handle which is bifurcated at an end remote from said actuating handle so as to provide a gap which encloses said clamping jaws whereafter said bearing member is formed as an extension of said actuating lever whereby in use both said clamping handle and said actuating handle are capable of being gripped in one hand for driving a pin into a bone wherein said pin is clamped between said pair of clamping jaws.
Claim 2
Dependent Claim
139 words
A surgical pin driver comprising a pair of elongate clamping jaws terminating in a clamping handle; a bearing member pivotally movable relative to said clamping jaws for engagement therewith to move said clamping jaws from an open position to a closed position and vice versa; a bridging member surrounding said clamping jaws wherein said bearing member is pivotally attached thereto; an actuating lever having an actuating handle which is bifurcated at an end remote from said actuating handle so as to provide a gap which encloses said clamping jaws whereafter said bearing member is formed as an extension of said actuating lever whereby in use both said clamping handle and said actuating handle are capable of being gripped in one hand for driving a pin into a bone wherein said pin is clamped between said pair of clamping jaws.
Claim 3
Dependent Claim
28 words
A surgical pin driver as claimed in claim 1 wherein there is provided a pair of pin locating grooves each located on opposed clamping faces of said jaws.
Claim 4
Dependent Claim
32 words
A surgical pin driver as claimed in claim 2 wherein there is provided a pair of guide lugs wherein each guide lug bounds a respective side of a first pin locating groove.
Claim 5
Dependent Claim
39 words
A surgical pin driver as claimed in claim 3 wherein there is provided a pair of mating sockets for said pair of guide lugs wherein each of said sockets bounds a respective side of a second pin locating groove.
Claim 6
Dependent Claim
36 words
A surgical pin driver as claimed in claim 1 wherein there is further provided biassing means associated with the jaws so as to facilitate movement of each jaw away from each other or the closed portion.
Claim 7
Dependent Claim
33 words
A surgical pin driver as claimed in claim 5 wherein each clamping jaw is joined to each other at a common end in such a manner so as to produce said biassing means.
