First Claim
Patent Images
1. An electrosurgical instrument, comprising:
- a) first means for performing a coagulating operation;
b) second means for performing a cutting operation;
c) means for moving the second means between an extended position and a retracted position such that when the first means is performing the coagulating operation the second means is in the retracted position and when the second means is performing the cutting operation the second means is in the extended position;
d) means for providing suction during both the coagulating operation and the cutting operation; and
e) means for controlling the operation of the first and second means.

Abstract
The invention includes an electrosurgical scalpel and a suction/coagulating tool provided in a single surgical instrument. The scalpel assumes an extended position when the instrument is used in a cutting mode and a retracted position when the tool is used in a coagulating mode. A push button control directs either continuous electrical current to the scalpel or pulsed electrical current to the suction/coagulating tool. Suction can be provided during both the cutting and coagulating procedures to maintain a clear field of vision.

7. An electrosurgical instrument comprising:
-
(a) a body portion; (b) a suction tube having a surface of conductive material extending from said body portion; (c) a scalpel blade supported for reciprocal movement in said body portion; (d) means for moving said scalpel blade between an extended and retracted position; and (e) a means for delivering current to said scalpel blade when said scalpel blade is in the extended position and for delivering current to said surface of the suction tube when said scalpel blade is in the retracted position. - View Dependent Claims (8, 9)
