Abstract
A first subassembly includes a body and an ultrasonic blade. A second subassembly is configured to removably couple with the first subassembly and includes a first clamp arm and a first clamp arm actuator. The first clamp arm is configured to be located on a first side of the longitudinal axis of the body, and the first clamp arm actuator is configured to be located on a second side of the longitudinal axis, when the second subassembly is coupled with the first subassembly. The third subassembly is similar to the second subassembly except that the second clamp arm of the third subassembly is configured to be located on the second side of the longitudinal axis of the body when the third subassembly is coupled with the first subassembly.
Claims20
A kit, comprising:
- (a) a first subassembly, wherein the first subassembly comprises:
- (i) a body, wherein the body defines a longitudinal axis, and
- (ii) an ultrasonic blade extending distally relative to the body;
- (b) a second subassembly, wherein the second subassembly is configured to removably couple with the first subassembly, wherein the second subassembly comprises:
- (i) a first clamp arm, wherein the first clamp arm is configured to be located on a first side of the longitudinal axis of the body when the second subassembly is coupled with the first subassembly, and
- (ii) a first clamp arm actuator, wherein the first clamp arm actuator is configured to be located on a second side of the longitudinal axis of the body when the second subassembly is coupled with the first subassembly, wherein the first clamp arm actuator is pivotable toward and away from the body to thereby pivot the first clamp arm toward and away from the ultrasonic blade when the second subassembly is coupled with the first subassembly;
- and
- (c) a third subassembly, wherein the third subassembly is configured to removably couple with the first subassembly, wherein the third subassembly comprises:
- (i) a second clamp arm, wherein the second clamp arm is configured to be located on the second side of the longitudinal axis of the body when the third subassembly is coupled with the first subassembly, and
- (ii) a clamp arm base, wherein the clamp arm base is configured to receive a distal portion of the body within the clamp arm base when the third subassembly is coupled with the first subassembly, wherein the clamp arm base remains fixed relative to the ultrasonic blade when the third subassembly is coupled with the first subassembly,
- wherein the clamp arm base is rotatably coupled to the second subassembly and the second clamp arm remains fixed relative to the ultrasonic blade while the first clamp arm is configured to be pivoted toward and away from the ultrasonic blade.
A kit, comprising:
- (a) a first subassembly, wherein the first subassembly comprises:
- (i) a body defining a longitudinal axis,
- (ii) a pair of arcuate channels, and
- (iii) an ultrasonic blade extending distally relative to the body;
- (b) a second subassembly, wherein the second subassembly is configured to removably couple with the first subassembly, wherein the second subassembly comprises:
- (i) a first clamp arm, wherein the first clamp arm is configured to be located on a first side of the ultrasonic blade when the second subassembly is coupled with the first subassembly, and
- (ii) a first clamp arm actuator, wherein the first clamp arm actuator is configured to be located on a second side of the longitudinal axis of the body when the second subassembly is coupled with the first subassembly, wherein the first clamp arm actuator is pivotable toward and away from the body to thereby pivot the first clamp arm toward and away from the ultrasonic blade when the second subassembly is coupled with the first subassembly, and
- (iii) a pair of detents configured to respectively mate with the pair of arcuate channels when the second subassembly is coupled with the first subassembly;
- and
- (c) a third subassembly, wherein the third subassembly is configured to removably couple with the first subassembly, wherein the third subassembly comprises:
- (i) a second clamp arm, wherein the second clamp arm is configured to be located on the second side of the longitudinal axis of the body when the third subassembly is coupled with the first subassembly, and
- (ii) a receiving member, wherein the receiving member is configured to receive a distal portion of the body when the third subassembly is coupled with the first subassembly.
A kit, comprising:
- (a) a first subassembly, wherein the first subassembly comprises:
- (i) a body, and
- (ii) an ultrasonic blade extending distally relative to the body;
- (b) a second subassembly, wherein the second subassembly is configured to removably couple with the first subassembly, wherein the second subassembly comprises:
- (i) a first clamp arm,
- (ii) a first clamp arm actuator, and
- (iii) a clamp pivot, wherein the first clamp arm and the first clamp arm actuator are pivotable together toward and away from the body about the clamp pivot to thereby pivot the first clamp arm toward and away from the ultrasonic blade when the second subassembly is coupled with the first subassembly;
- and
- (c) a third subassembly, wherein the third subassembly is configured to removably couple with the first subassembly, wherein the third subassembly comprises:
- (i) a tissue stop configured to receive the ultrasonic blade inserted therein, wherein the tissue stop is configured to prevent tissue from moving proximally when a tissue is clamped between the first clamp arm and the ultrasonic blade,
- (ii) a first pivot, wherein the first clamp arm is pivotable about the first pivot to thereby pivot the first clamp arm toward and away from the ultrasonic blade when the third subassembly is coupled with the first subassembly, and
- (iii) a second pivot, wherein the first clamp arm actuator is pivotable about the second pivot to thereby drive the first clamp arm to pivot the first clamp arm toward and away from the ultrasonic blade when the third subassembly is coupled with the first subassembly.
