Abstract
Abstract One surgical device includes a transducer assembly adapted to vibrate at an ultrasonic frequency in response to electrical energy. A first transmission component is adapted to receive and transmit the ultrasonic vibration from a first end to a second end. A second transmission component is adapted to receive and transmit the ultrasonic vibrations from a first end to a second end. A torque limiting device coupled to the second transmission component limits the torque when the second end of the first transmission rod is coupled to the first end and a method of attaching a transmission component is also provided. A method in accordance with the present invention includes the steps of providing a handpiece assembly having an integral torque limiting mechanism and a first transmission component and threading a second transmission component onto the first transmission component of the handpiece assembly. The method also includes the steps of rotating a sleeve of the handpiece assembly until the second transmission component has been tightened to a predetermined torque on the first transmission component of the handpiece assembly.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
131 words
An ultrasonic surgical instrument comprising: a working member having a first end and a second end, the working member adapted to receive ultrasonic vibration and to transmit the ultrasonic vibration from the first end to the second end of the working member; a collar coupled to the working member, the collar having at least one tooth like member; an adapter having at least one pawl-like member wherein the at least one pawl-like member of the adapter is engageable with the at least one tooth-like member of the collar so that the collar can rotate with the rotation of the adapter and the at least one pawl-like member of the adapter to slip out of engagement with the at least one tooth-like member of the collar when a predetermined torque is applied.
Claim 2
Dependent Claim
131 words
An ultrasonic surgical instrument comprising: a working member having a first end and a second end, the working member adapted to receive ultrasonic vibration and to transmit the ultrasonic vibration from the first end to the second end of the working member; a collar coupled to the working member, the collar having at least one tooth like member; an adapter having at least one pawl-like member wherein the at least one pawl-like member of the adapter is engageable with the at least one tooth-like member of the collar so that the collar can rotate with the rotation of the adapter and the at least one pawl-like member of the adapter to slip out of engagement with the at least one tooth-like member of the collar when a predetermined torque is applied.
Claim 3
Dependent Claim
31 words
The device of claim 1 wherein the height of the at least one pawl-like member and at least one tooth-like member extends substantially parallel to the axis of the working member.
Claim 4
Dependent Claim
27 words
The device of claim 1 wherein the height of the at least one pawl-like member and at least one tooth-like member extends in a substantial radial direction.
Claim 5
Dependent Claim
14 words
The device of claim 1 wherein the adapter includes a plurality of pawl-like members.
Claim 6
Dependent Claim
14 words
The device of claim 1 wherein the collar includes a plurality of tooth-like members.
Claim 7
Dependent Claim
17 words
The device of claim 1 wherein the working member comprises a transmission rod and an end effector.
Claim 8
Dependent Claim
37 words
The device of claim 1 wherein the at least one tooth-like member is disposed on the outer periphery of the collar and the at least one pawl-like member is disposed on the inner surface of the adapter.
Claim 9
Dependent Claim
104 words
A surgical device comprising: a transducer adapted to vibrate at an ultrasonic frequency in response to electrical energy; a housing carrying the transducer, the housing having an outer surface; a tooth-like member disposed on the outer surface of the housing; a sleeve disposed around the housing, the sleeve having an inner surface; a pawl-like member disposed on the inner surface of the sleeve to engage the tooth-like member of the housing so that the sleeve can rotate with the housing until the pawl-like member of the sleeve slips out of engagement with the tooth-like member of the housing when a predetermined torque is applied.
Claim 10
Dependent Claim
104 words
A surgical device comprising: a transducer adapted to vibrate at an ultrasonic frequency in response to electrical energy; a housing carrying the transducer, the housing having an outer surface; a tooth-like member disposed on the outer surface of the housing; a sleeve disposed around the housing, the sleeve having an inner surface; a pawl-like member disposed on the inner surface of the sleeve to engage the tooth-like member of the housing so that the sleeve can rotate with the housing until the pawl-like member of the sleeve slips out of engagement with the tooth-like member of the housing when a predetermined torque is applied.
Claim 11
Dependent Claim
73 words
A surgical instrument comprising: a working member adapted to contact tissue of a patient; a collar coupled to the working member, the collar having teeth means; and an adapter having pawl means engageable with the teeth menas of the collar so that the collar will rotate with the rotation of the adapter until the pawl means of the adapter slips past the teeth means of the collar when a predetermined torque is applied.
Claim 12
Dependent Claim
73 words
A surgical instrument comprising: a working member adapted to contact tissue of a patient; a collar coupled to the working member, the collar having teeth means; and an adapter having pawl means engageable with the teeth menas of the collar so that the collar will rotate with the rotation of the adapter until the pawl means of the adapter slips past the teeth means of the collar when a predetermined torque is applied.
