Abstract
A suturing system for a scope having a scope shaft comprises a drive shaft to extend along the scope shaft, a mounting ring to mount to a distal end of the scope shaft to receive the drive shaft, a pinion gear mounted to a distal end of the drive shaft, a ring gear rotatably mounted to the mounting ring in engagement with the pinion gear, and a needle mounted to the ring gear.
Claims19
A suturing system for coupling to a scope having a scope shaft, the suturing system comprising:
- a drive shaft configured to extend along the scope shaft, the drive shaft configured to rotate;
- a mounting ring configured to mount to a distal end of the scope shaft to receive the drive shaft, the mounting ring comprising:
- an annular body defining an opening to allow features of an end face of an endoscope access through the mounting ring;
- and
- a socket configured to receive a stop from a working channel of the scope shaft when the suturing system is coupled to the scope shaft;
- a pinion gear mounted to a distal end of the drive shaft;
- a ring gear rotatably mounted to the mounting ring in engagement with the pinion gear, wherein the pinion gear is configured to rotate the ring gear about the mounting ring when the drive shaft is rotated;
- and
- a needle mounted to the ring gear, the needle shaped to receive the stop from the socket.
6 more elements
A system for endoscopic suturing comprising:
- a scope shaft extending along a central longitudinal axis, the scope shaft comprising a proximal end portion and a distal end face, wherein the distal end face comprises a working channel and an imaging lens;
- an electric motor coupled to the scope shaft at the proximal end portion;
- a drive shaft extending along an exterior of the scope shaft from the electric motor to proximate the distal end face;
- a mounting ring configured to attach to the distal end face of the scope shaft, the mounting ring comprising:
- an opening to allow the imaging lens to view through the mounting ring;
- and
- a socket for receiving a suture stop from the working channel of the scope shaft;
- a suturing element movably mounted to the mounting ring to move distal of the distal end face, the suturing element comprising a helically shaped needle having a tip socket configured to hold a suture stop;
- and
- a gear system connecting the drive shaft and the suturing element;
- wherein the gear system is configured to convert rotational movement of the drive shaft into a rotational suturing stroke of the suturing element so that the suturing element can receive the suture stop from the socket.
