Abstract
Abstract A surgical instrument for obtaining biopsies, performing microsurgery and bipolar microelectrocautery. The instrument head includes opposing jaw members which open and close during the operating procedures. The angle of the instrument head relative to the instrument frame is adjustable to effectively operate on varying surfaces. The angle can be continuously adjusted while the instrument is in an operating position.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
115 words
A medical instrument for performing surgical procedures, comprising: a longitudinal instrument frame; an instrument head connected to a first end of said frame, said head including two jaw members connected to said frame for relative movement toward and away from each other; a handle means connected to a second end of said frame for holding said instrument frame and connected to said head for moving at least one of said jaw members; means connected to said frame and said head for adjusting the angular position of said head relative to said frame in a fixed plane, said relative movement of said jaws occurring in said fixed plane; and said adjusting means including said handle means.
Claim 2
Dependent Claim
115 words
A medical instrument for performing surgical procedures, comprising: a longitudinal instrument frame; an instrument head connected to a first end of said frame, said head including two jaw members connected to said frame for relative movement toward and away from each other; a handle means connected to a second end of said frame for holding said instrument frame and connected to said head for moving at least one of said jaw members; means connected to said frame and said head for adjusting the angular position of said head relative to said frame in a fixed plane, said relative movement of said jaws occurring in said fixed plane; and said adjusting means including said handle means.
Claim 3
Dependent Claim
41 words
An instrument as defined in claim 1 in which said adjusting means further includes a bar for adjusting the angular position of said head in a first direction and a second direction, said second direction being opposite to said first direction.
Claim 4
Dependent Claim
23 words
An instrument as defined in claim 2 in which said handle means adjusts the angular position of said head in said second direction.
Claim 5
Dependent Claim
31 words
An instrument as defined in claim 3 in which said adjusting means includes a rotating means which rotates in said first and second directions in response to movement of said bar.
Claim 6
Dependent Claim
36 words
An instrument as defined in claim 4 in which said rotating means is coupled to a first means for changing the relative angular position of a first one of said jaw members relative to said frame.
Claim 7
Dependent Claim
35 words
An instrument as defined in claim 5 in which said handle means is coupled to a second means for changing the angular position of a second one of said jaw members relative to said frame.
Claim 8
Dependent Claim
52 words
An instrument as defined in claim 6 in which said adjustment means includes means for engaging said rotating means and for arresting movement of said rotating means in said second direction thereby inhibiting said first changing means from changing said relative angular position of said first jaw member in said second direction.
Claim 9
Dependent Claim
52 words
An instrument as defined in claim 7 in which disengagement of said arresting means enables said handle means to change the angular position of said second jaw member and the angular position of said first jaw member after said first and second jaw members have been moved together by said handle means.
Claim 10
Dependent Claim
18 words
An instrument as defined in claim 1 in which each of said jaw members includes a cutting blade.
Claim 11
Dependent Claim
15 words
An instrument as defined in claim 9 in which said cutting blades are razor-edged blades.
Claim 12
Dependent Claim
53 words
An instrument as defined in claim 10 in which each said razor-edged blade includes a sharpened tip and the tip of one of said blades on a first jaw member slides next to and past the tip of a second blade on a second jaw member when said jaw members are closed together.
Claim 13
Dependent Claim
19 words
An instrument as defined in claim 10 in which said razor-edged blades are removably attachable to said jaw members.
Claim 14
Dependent Claim
15 words
An instrument as defined in claim 10 in which said cutting blades are scissor blades.
Claim 15
Dependent Claim
47 words
An instrument as defined in claim 13 in which a first one of said scissor blades is double-edged and a second one of said scissor blades is single-edged such that the single-edged scissor blade fits within the double-edged scissor blade when said jaw members are closed together.
Claim 16
Dependent Claim
17 words
An instrument as defined in claim 1 in which each of said jaw members includes an electrode.
Claim 17
Dependent Claim
18 words
An instrument as defined in claim 15 in which said electrodes are removably attachable to said jaw members.
Claim 18
Dependent Claim
23 words
An instrument as defined in claim 16 in which said electrodes are attached to electrical leads for supplying electrical current to said electrodes.
