Title:
SURGICAL STAPLER HAVING POWERED HANDLE
Document Type and Number:
Japanese Patent JP2023130373
Kind Code:
A
Abstract:
To provide reliable stapling of clamped tissue without complex mechanisms.SOLUTION: A powered handle for a surgical stapler has a drive system including an electric motor. The powered handle includes a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism includes a ball screw mechanism that translates an articulation member in response to rotation of an articulation knob. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system controls actuation of the motor based on user inputs and operating parameters of the stapler. The powered handle includes a manual return mechanism.SELECTED DRAWING: Figure 14
