Abstract
Disclosed is a surgical device (1) is for attaching a non-woven textile to human or animal soft tissue by releasing sections of individual fibers of the non-woven textile and carrying them into the human or animal soft tissue, the device comprising a carrier (4) extending in a longitudinal direction (x), comprising a guide rod (5) and a felting needle (6) attached to a distal end of the guide rod (5), wherein the guide rod (5) comprises a dorsal end (13) which is coupled to a driving mechanism (14) via a force limiting element (15) which during operation limits the force applied by the driving mechanism (14) to the guide rod (5) to a predetermined force threshold when the working tip (7) is moved from a retracted position to an extended position.
Claims21
A surgical device for attaching a non-woven textile to human or animal soft tissue by releasing sections of individual fibers of the non-woven textile and carrying them into the human or animal soft tissue, the device comprising:
- a. a carrier extending in a longitudinal direction, comprising a guide rod and a felting needle attached to a distal end of the guide rod, wherein
- b. the guide rod and the felting needle are at least partially arranged in a guide bushing and the felting needle is reciprocally movable between
- i. an extended position in which a working tip of the felting needle protrudes beyond an aperture arranged at a distal end of the guide bushing and
- ii. a retracted position in which the working tip of the felting needle does not protrude beyond the aperture arranged at the distal end of the guide bushing;
- wherein
- c. the guide rod comprises a dorsal end which is coupled to a driving mechanism via a force limiting element which during operation limits the force applied by the driving mechanism to the guide rod to a predetermined force threshold when the working tip is moved from the retracted position to the extended position.
