Cartridge interface for surgical suturing device
First Claim
Patent Images
1. A surgical suturing system, the system comprising:
- a reusable instrument having a shaft comprising a proximal end, a distal end, a longitudinal axis between the proximal and distal ends, and a receiver on the distal end with a rotary drive comprising a first torsional coupling;
a disposable cartridge arranged as a modular unit configured for ready insertion into and removal from the receiver, the cartridge comprising a cartridge housing, a surgical needle, a length of suture connected to the needle, a needle driver operative to engage and move the needle relative the cartridge, a transmission operatively connected to the needle driver, and a second torsional coupling configured to rotationally join with the first torsional coupling such that the torsional couplings are axially aligned and maintain angular correspondence and thereby connect the rotary drive to the transmission.

Abstract
A surgical suturing system comprises a shaft having a proximal end, a distal end, a longitudinal axis between the proximal and distal ends, and receiver on the distal end with a rotary drive. A cartridge is selectively attachable to and detachable from the receiver. The cartridge has a surgical needle, a length of suture connected to the needle, a needle driver operative to engage and move the needle relative the cartridge, a transmission operatively connected to the needle driver, and a torsional interface rotationally coupling the rotary drive to the transmission.

12. A surgical suturing system, the system comprising:
-
a shaft comprising a proximal end, a distal end, and a longitudinal axis between the proximal and distal ends; a receiver on the distal end of the shaft, the receiver comprising a pair of distally extending arms defining a space between the arms, one of the arms having a rotating drive with a first rotary coupling; a cartridge arranged as a modular unit configured for ready insertion into and removal from the receiver by longitudinally sliding the cartridge in the space, the cartridge comprising a cartridge housing, a surgical needle, a length of suture connected to the needle, a needle driver operative to engage and move the needle relative the cartridge, and a transmission operably connected to the needle driver having a second rotary coupling configured to mate with the rotary coupling thereby transferring torque and maintaining axial alignment angular correspondence between the first and second rotary couplings; and a latch selectively locking and unlocking the cartridge in the receiver.
