摘要:
A surgical stapler includes a head in which a plurality of staples are stored. The head includes a facing surface. The stapler also includes an anvil having an anvil surface shaped and dimensioned for forming the staples upon actuation of the surgical stapler, the anvil including a facing surface opposed to the facing surface of the head for mating engagement therewith. The facing surface of the head is obliquely oriented relative to a longitudinal axis of the head creating an elliptical staple line when the head is brought into contact with anvil during actuation of the surgical stapler.

A positioning device for deploying at least one locking portion (20) of an anastomotic device (10) for drawing together a first tissue portion (12) and a second tissue portion (14) to be connected by means of anastomosis is suitable for sliding along a guide means comprising at least one guide wire (A, B) and comprises an elongated structure (50). A head (52) of the positioning device is suitable to be interference-inserted on a distal end of the elongated structure (50). The head (52) comprises elastic tabs (54) extending from a proximal end of the head and at least one channel (56) suitable for receiving a guide wire. The head (52) comprises a distal end defining a thrust surface (58) for a locking portion (20) of the anastomotic device (10).

Traction means (14) for excising a tissue sample comprising a distal portion (14a), comprising at least one clip (20) suitable for being fixed to at least one portion (12) of tissue to be excised and a proximal portion (14b) suitable for being subjected to traction. Said at least one clip (20) is suitable for being connected to a distal end (22a) of a suture (22) to pull the tissue to be excised, said suture (22) extending between said distal end (22a) and a proximal end corresponding to the proximal portion of said traction means (14). Moreover, said at least one clip (20) is connected to a ring (24) formed at a distal end (24a) of said suture (22) to pull the tissue to be excised.
摘要:
A device for the intraluminal treatment of tissue comprises a handle, a shaft which extends from the handle and a head arranged at the distal end of the shaft, wherein the head comprises at least one jaw, movable between an open position, wherein it defines a window for the insertion of the tissue and surrounding tissue, and a closed position, and wherein the shaft extends between the handle and head in a curvilinear longitudinal direction.
摘要:
A deployment system for introducing a surgical instrument (2) in a patients body by means of an elongate insertion device (8) which can be inserted in the patients body includes a coupling device (9, 15, 21) connectable with the surgical instrument (2) and shiftably connectable with the insertion device (8) such that the surgical instrument (2) can slide along the insertion device (8) in a guided manner, wherein the coupling device (9) includes one or more roller elements (10) configured to rollably contact the insertion device (8).

摘要:
A surgical stapling instrument comprises a cartridge device with a row of staples and a wavy first tissue interface, and an anvil having a wavy second tissue interface which cooperates with the first tissue interface for clamping tissue therebetween and forming the staples exiting from the cartridge device, a staple driving device adapted to drive the staples out of the cartridge device towards the anvil, wherein the staples are non-symmetrical U-shaped with two legs protruding toward the anvil and a transverse basis connecting the legs, wherein the basis is inclined with respect to the longitudinal direction of the legs and has a length greater than the staple projection on a plane perpendicular to the longitudinal direction of the legs.
摘要:
An anastomotic device (10) is suitable for approximating and keeping close to each other a first tissue portion (12) and a second tissue portion (14) intended to form an anastomosis. The anastomotic device (10) comprises an abutment portion (18) suitable for the abutment against a surface of the first tissue portion (12) and a locking portion (20) suitable for being placed opposite the abutment portion (18) with respect to the first and second tissue portion (12, 14). The locking portion (20) and the abutment portion (18) are mutually connectable through the first and second tissue portions approximated, to keep them connected. The anastomotic device (10) is suitable for being connected to a guide means comprising at least one guide wire (A, B).
