Surgical device, surgical adapters for use between surgical handle assembly and surgical loading units, and methods of use
First Claim
1. A surgical device, comprising:
- a handle housing supporting a first actuation mechanism;
an adapter including a first drive assembly configured to mechanically engage a portion of the first actuation mechanism, the first drive assembly including first and second portions formed as a single construct;
an elongated portion configured to extend distally from the adapter and defining a longitudinal axis;
an end effector configured to mechanically engage a distal portion of the elongated portion;
a first drive element disposed in mechanical cooperation with the first portion of the first drive assembly; and
a second drive element disposed in mechanical cooperation with the second portion of the first drive assembly;
wherein the first and second drive elements and the first drive assembly are coaxially arranged, wherein rotation of the first drive assembly in a first direction about the longitudinal axis causes distal translation of the first drive element, wherein rotation of the first drive assembly in a second direction about the longitudinal axis causes distal translation of the second drive element, and wherein the first direction is opposite from the second direction.

Abstract
A surgical device comprising a handle housing, an adapter, an elongated portion, an end effector, a first drive element, and a second drive element is disclosed. The adapter includes a first drive assembly configured to mechanically engage a portion of a first actuation mechanism of the handle housing. The elongated portion is configured to extend distally from the adapter. The first drive element is disposed in mechanical cooperation with the first drive assembly. The second drive element is disposed in mechanical cooperation with the first drive assembly. Rotation of the first drive assembly in a first direction about the longitudinal axis causes distal translation of the first drive element. Rotation of the first drive assembly in a second direction about the longitudinal axis causes distal translation of the second drive element. The first direction is opposite from the second direction.

14. A surgical device, comprising:
-
a handle housing supporting an actuation mechanism; a drive assembly disposed in mechanical cooperation with a portion of the actuation mechanism, the drive assembly including first and second portions formed as a single construct; an elongated portion defining a longitudinal axis; an end effector disposed adjacent a distal portion of the elongated portion; a first drive element threadably engaged with the first portion of the drive assembly; and a second drive element threadably engaged with the second portion of the drive assembly; wherein the first and second drive elements and the drive assembly are coaxially arranged; wherein rotation of the drive assembly in a first direction about the longitudinal axis results in distal translation of the first drive element to effect a first surgical function, wherein rotation of the drive assembly in a second direction about the longitudinal axis results in distal translation of the second drive element to effect a second surgical function, wherein the first direction is opposite from the second direction, and wherein the first surgical function is different from the second surgical function. - View Dependent Claims (15, 16, 17, 18)

19. A surgical adapter for mechanically engaging a powered assembly having an actuation assembly, the adapter comprising:
-
a drive assembly disposed in mechanical cooperation with a portion of the actuation mechanism, the drive assembly including first and second portions formed as a single construct; a first drive element threadably engaged with the first portion of the drive assembly; and a second drive element threadably engaged with the second portion of the drive assembly; wherein the first and second drive elements and the drive assembly are coaxially arranged;
wherein rotation of the drive assembly in a first direction results in distal translation of the first drive element to effect a first surgical function, wherein rotation of the drive assembly in a second direction results in distal translation of the second drive element to effect a second surgical function, wherein the first direction is opposite from the second direction, and wherein the first surgical function is different from the second surgical function. - View Dependent Claims (20)
