Cutting device for surgical threads

A cutting device for surgical threads comprising:

• a guide body having a tubular shape extending along a longitudinal axis, having an internal axial cavity defining a housing portion adapted to receive a surgical thread, said guide body comprising a first end, which is at least partially open to allow insertion of the surgical thread, a second end, and a first cutting area defined by an abutment surface of the guide body oriented transversely to the longitudinal axis of the guide body;
• a cutting body comprising:
• a central portion extending along a longitudinal axis and adapted to be inserted in said housing portion;
• said central portion having a section transverse to said longitudinal axis of said cutting body such as to define, when coupled in said housing portion, a passage channel, extending parallel to the longitudinal axis of said guide body, for housing said surgical thread;
• a first end equipped with a second cutting area defined by an abutment surface of the cutting body oriented transversely to the longitudinal axis of the cutting body;
• said second cutting area abutting against the first cutting area when said cutting body is at least partially received in the housing portion;
• said abutment surface of the cutting body having an angle comprised between 150° and 170° to define a housing zone for said surgical thread;
• and
• a second end;
• and
• an actuator element, capable of causing said cutting body to rotate relative to said guide body about said longitudinal extension axis of said cutting body between a first position, in which the abutment surfaces of said guide body and said cutting body, respectively, are arranged relative to each other so as to identify a passageway at the first ends of said housing portion and said second cutting area, respectively, communicating with said internal axial cavity, and a second position, in which said passageway is at least partially obstructed by the counter-rotating movement of said abutment surfaces, which intersect tangentially so as to cut the surgical thread therebetween;
• wherein the guide body has a coupling area adapted to provide an axially stable connection between the guide body and the cutting body;
• wherein said coupling area comprises an annular groove formed at the second end of said guide body, adapted to receive a corresponding radial projection provided at the second end of said cutting body, so as to allow mutual engagement, correct and stable relative axial positioning, and relative rotation between said cutting body and the guide body.
