DEVICE FOR CUTTING SUTURE FROM A DISTANCE

摘要

The present disclosure provides a cutting assembly for cutting an object, such as a suture, within the body of a patient. The cutting assembly comprises a housing, a proximal cutting element, a distal cutting element, and an actuating member. Both the proximal and distal cutting elements have a cutting surface or blade. The blades face each other within the housing and actuate towards each other to cut the suture. The housing further comprises a plurality of slots that house the blades and maintain them in the orientation desired for cutting. The housing further comprises openings to guide the suture through the cutting assembly. The cutting assembly provides sufficient flexibility to be oriented at the suture location, but maintains its rigidity to effectuate a sufficient, clean cut.

主权项

1. A cutting assembly for cutting an object in a body of a patient, the cutting assembly comprising:
a housing being tubular and having a proximal end and extending along a longitudinal axis to a distal end with a housing lumen formed therethrough; a proximal cutting element disposed in the housing lumen and comprising a first end distal the proximal end, the first end extending along the longitudinal axis to a second end, defining a first plane, the second end comprising a proximal cutting surface; and a distal cutting element disposed in the housing lumen distal the proximal cutting element and comprising a third end extending along the longitudinal axis to a fourth end, defining a second plane being parallel with the first plane, the third end comprising a distal cutting surface, one of the proximal and distal cutting elements being operable along the longitudinal axis such that the cutting assembly has an open position and a closed position, the distal cutting surface being distal the proximal cutting surface a first distance (d) in the open position, the distal cutting surface being proximal the proximal cutting surface a second distance (o) in the closed position, the proximal and distal cutting surfaces cooperating to cut the object in the body.
