Appl. No.:

09/726490

Inventors:

Stephen J. Perry - Shirley MA 01464
Eric K. Litscher - Hopkinton MA 01748

International Classification:

A61B 17068

US Classification:

2271752, 227 19

Abstract:

A safety lock-out to prevent rotation of a rotary actuator is described. When an axial distance between a first and a second portion of an actuated mechanism exceeds a selected distance, the lock-out prevents the rotation. The safety lock-out includes a shaft rotatably connected to the first portion and axially movable relative to the second portion. A locking member is adapted to lock the rotary actuator by placing a protrusion in a notch of the shaft, thus preventing rotation of the shaft. The device also includes a spring member urging the locking member in the locking position, and an unlocking member adapted to urge the locking member in the unlocked position when the selected distance is not exceeded.

US Classification:

606139

Abstract:

A control handle for a full thickness resection device is disclosed. In an embodiment for the control handle of the present invention, the control handle includes a body and a staple firing assembly coupled to the body. The staple firing assembly includes a rotatable staple firing ring, a worm gear assembly rotatably engaged with the staple firing ring, and a flexible drive shaft coupled to the worm gear assembly. In an embodiment for a method of the present invention, a method for actuating a full thickness resection device is provided. The method includes the steps of rotating a staple firing ring in a first direction and actuating a worm gear assembly in a first operative mode in response to the rotation of the staple firing ring in the first direction, the worm gear assembly is coupled to the staple firing ring. A flexible drive shaft is rotated in the first direction, the flexible drive shaft being coupled to the worm gear assembly, and torsional energy is stored in the flexible drive shaft during rotation of the flexible drive shaft in the first direction. The worm gear assembly is actuated in a second operative mode and a release rate of the stored torsional energy in the flexible drive shaft is controlled by the worm gear assembly.

International Classification:

A61B 1704

US Classification:

606139, 606 1

Abstract:

A control mechanism for a resectioning device, comprises a first actuator coupled to a flexible drive shaft for actuating a first mechanism when operated in a first direction and for actuating, when operated in a second direction, a second mechanism and a first lockout mechanism coupled to the first actuator for preventing actuation of the first actuator in the second direction before a predetermined amount of actuation in the first direction has been completed. Furthermore, mechanisms are provided to control the release during operation in a second direction of torsional energy stored in a flexible drive shaft during operation in a first direction.
