Abstract
A suture delivery tool releasably secures a self-retaining suture to permit delivery of the self-retaining suture to a surgical site in a patient through an access port. Suture delivery tools are disclosed suitable for manual operation and operation using robotically-assisted surgical systems. In some embodiments, a suture spool is part of a cartridge which is releasably attached to the suture delivery tool. Cartridges is, in some embodiments, replaced after deployment of the self-retaining suture and different cartridges having different self-retaining suture are, in some embodiments, selected and attached to the suture delivery tool as required for a procedure.
Claims8
A suture dispenser, comprising:
- a self-retaining suture having an elongated suture body with a first segment having a first plurality of retainers disposed proximally to a first end, and a second segment having a second plurality of retainers disposed proximally to a second end and first and second needles disposed at the first and second ends respectively;
- an elongated shaft;
- a spool positioned at a distal end of the elongated shaft, the spool comprising first and second needle docks adjacent to each other at a distal end thereof, the self-retaining suture being releasably secured to the spool and the first and second needles being releasably secured to one of the first and second needle docks respectively;
- and
- an actuator attached to a proximal end of the elongated shaft by which the dispenser is manipulated to introduce the spool and distal end of the elongated shaft through an access port into a surgical site within a patient.
A suture dispenser, comprising:
- a self-retaining suture having an elongated suture body with a first segment having a plurality of retainers disposed proximally to a first end, and a second segment having a plurality of retainers disposed proximally to a second end and first and second needles disposed at the first and second ends respectively;
- an endoscopic tool comprising an elongated tube;
- a suture cartridge positioned within a distal end of the elongated tube, the suture cartridge comprising first and second needle docks at a distal end thereof, the self-retaining suture being releasably secured to the suture cartridge and the first and second needles being releasably secured to one of the first and second needle docks respectively;
- and
- an interface attached to a proximal end of the elongated shaft by which the dispenser is manipulated to introduce the distal end of the elongated shaft through an access port into a surgical site within a patient.
