Abstract

Abstract 1. Operating instrument with an ultrasonic drill probe (1) for shattering calculi in the human body, particularly hepatoliths and ureatoliths by means of ultrasonic energy, forceps (2-5) being associated with the tubular ultrasonic probe (1), characterised in that the tubular ultrasonic drill probe (1) is constructed as an actuator for the two outwardly springing legs (2, 3) of the forceps constructed as part of a leg spring, both legs (2, 3) by actuating an actuating device at the patient-remote end axially springloaded can be moved out of the patient-near end of the tubular ultrasonic probe (1).

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 96 words
Operating instrument with an ultrasonic drill probe (1) for shattering calculi in the human body, particularly hepatoliths and uretoiiths by means of ultrasonic energy, forceps (2-5) being associated with the tubular ultrasonic probe (1), characterised in that the tubular ultrasonic drill probe (1) is constructed as an actuator for the two outwardly springing legs (2, 3) of the forceps constructed as part of a leg spring, both legs (2. 3) by actuating an actuating device at the patient- remote end axially springloaded can be moved out of the patient-near end of the tubular ultrasonic probe (1).
Claim 2
Dependent Claim 96 words
Operating instrument with an ultrasonic drill probe (1) for shattering calculi in the human body, particularly hepatoliths and uretoiiths by means of ultrasonic energy, forceps (2-5) being associated with the tubular ultrasonic probe (1), characterised in that the tubular ultrasonic drill probe (1) is constructed as an actuator for the two outwardly springing legs (2, 3) of the forceps constructed as part of a leg spring, both legs (2. 3) by actuating an actuating device at the patient- remote end axially springloaded can be moved out of the patient-near end of the tubular ultrasonic probe (1).
Claim 3
Dependent Claim 25 words
Operating instrument according to claim 1, characterised in that the legs (2, 3) are connected in one piece with a spatially wound spiral spring (4).
Claim 4
Dependent Claim 40 words
Operating instrument according to claim 1, characterised in that the wire leading to the two legs (2, 3), comprises two cores (6. 7) and a rivet holding together in juxtaposed manner the ends provided with the wound spiral spring (4).
Claim 5
Dependent Claim 18 words
Operating instrument according to claim 3, characterised in that the two cores (6, 7) are helically braided together.
Claim 6
Dependent Claim 33 words
Operating instrument according to claim 1 or one of the preceding claims, characterised in that the tubular ultrasonic probe (1) has slots (8, 9) for guiding legs (2, 3) at the patient-near end.
Claim 7
Dependent Claim 48 words
Operating instrument, particularly for gripping calculi, with forceps having two legs, which are axially moveable with respect to a guide tube, the legs being actuated through the tube opening, characterised in that the legs (2, 3) are connected in one piece with a spatially wound spiral spring (4).
Claim 8
Dependent Claim 48 words
Operating instrument, particularly for gripping calculi, with forceps having two legs, which are axially moveable with respect to a guide tube, the legs being actuated through the tube opening, characterised in that the legs (2, 3) are connected in one piece with a spatially wound spiral spring (4).
