Device for use in cutting threads
First Claim
1. A device for endoscopically cutting a surgical thread, which comprises a cutting member having proximal and distal ends and having at least one aperture extending therethrough of a size sufficient to permit the surgical thread to slide therethrough, the aperture having a proximally facing thread-cutting edge and the cutting member being movably mounted with respect to the distal end of an endoscope whereby the surgical thread is cut by proximal movement of the cutting member relative to the thread.

Abstract
A device is provided for cutting threads, particularly curing surgery carried out using an endoscope. The device has a cutting member having at least one aperture extending therethrough of a size sufficient to permit the surgical thread to slide therethrough, the aperture having a thread-cutting edge. In use, the cutting member is located at the distal end of an endoscope.

10. A method of cutting a surgical thread at a suture site within a patient comprising:
-
providing an endoscope having proximal and distal ends; providing a cutting member having proximal arid distal ends and having at least one aperture extending therethrough of a size sufficient to permit the surgical thread to slide therethrough, the aperture having a proximally facing thread-cutting edge, and the cutting member being movably mounted with respect to the distal end of an endoscope, inserting the cutting member into and through the endoscope such that the cutting member protrudes at least slightly from the distal end of the endoscope; inserting the surgical thread through the aperture(s) of the cutting member then holding the surgical thread in tension while advancing the cutting member and endoscope into the patient to the suture site; withdrawing the cutting member proximally relative to the thread to cut the thread with the thread-cutting edge.

11. A method of cutting a surgical thread at a suture site within a patient comprising:
-
providing an endoscope having proximal and distal ends; providing a cutting member having at least one thread-cutting edge and being movably mounted with respect to the distal end of the endoscope; placing the surgical thread in tension; moving the thread cutting member proximally relative to the distal end of the endoscope to cause the angle between the longitudinal axis of the thread and axis of movement of the cutting member to increase such that the thread becomes cut against the thread cutting edge.

12. A device for endoscopically cutting a surgical thread, which comprises a cutting member having at least one aperture extending therethrough of a size sufficient to permit the surgical thread to slide therethrough, the aperture having a single thread-cuffing edge that is the sole means for cutting the thread and the cutting member being movably mounted with respect to the distal end of a flexible endoscope.

13. A device for cutting a surgical thread within a patient, which comprises a cutting member having proximal and distal ends and having at least one aperture extending therethrough of a size sufficient to permit the surgical thread to slide therethrough, the aperture having a proximally facing thread-cutting edge, and the cutting member being slidably receivable in a tubular shaft that is positionable to introduce the cutting member into the patient whereby the surgical thread is cut by proximal movement of the cutting member relative to the thread.
