Hand held surgical handle assembly, surgical adapters for use between surgical handle assembly and surgical end effectors, and methods of use

摘要

Adapter assemblies are provided for selectively interconnecting a surgical end effector that is configured to perform at least a pair of functions and a surgical device that is configured to actuate the end effector, wherein the end effector includes a first axially translatable drive member and a second axially translatable drive member, and wherein the surgical device includes a first rotatable drive shaft and a second rotatable drive shaft.

主权项

1. An electromechanical surgical system, comprising:
a hand-held surgical device, including:
a device housing defining a connecting portion;at least one drive motor supported in the device housing and being configured to rotate a first drive shaft of the surgical device;a battery disposed within the device housing for powering the at least one drive motor; anda circuit board disposed within the device housing for controlling power delivered from the battery to at least one drive motor; an end effector configured to perform at least one function, the end effector including at least one axially translatable drive member; and an adapter assembly for selectively interconnecting the end effector and the surgical device, the adapter assembly including:
an adapter housing configured and adapted for selective connection to the connecting portion of the surgical device and to be in operative communication with the first drive shaft of the surgical device;an outer tube having a proximal end supported by the adapter housing and a distal end configured and adapted for connection with the end effector, wherein the distal end of the outer tube is in operative communication with each of the at least one axially translatable drive member of the end effector; anda first drive converter assembly including:
a first distal drive shaft rotatably supported in the adapter housing, wherein a proximal end of the first distal drive shaft is connectable to the first drive shaft of the surgical device;a drive coupling nut threadably connected to a threaded distal portion of the first distal drive shaft, wherein the drive coupling nut is keyed against rotation within the adapter housing; anda drive tube having proximal end connected to the drive coupling nut and the distal end configured for selective engagement with the at least one axially translatable drive member of the end effector;wherein rotation of the first drive shaft of the surgical device results in rotation of the first distal drive shaft, and wherein rotation of the first distal drive shaft results in axial translation of the drive coupling nut, the drive tube and the at least on axially translatable drive member of the end effector.
