An apparatus for suturing includes an inner strut, a spiral suturing needle, a driving mechanism, a recovery mechanism, a suture-taking-up mechanism, and a suture-feeding mechanism. Grooves are distributed on periphery with respect to an axial direction of the inner strut, a path of the groove is consistent with a path of a metallic stent to be sutured, and a width of the groove matches an outer diameter of the spiral suturing needle; the spiral suturing needle is an elastic retractable structure and a length of the spiral suturing needle without deformation is longer than a length of the path of the groove, and a suturing needle tip is arranged on a head portion of the spiral suturing needle and a suture-piercing hole is arranged on a tail portion of the spiral suturing needle.

DEVICES FOR CONTINUOUS SURGICAL SUTURING

A surgical suture module for a machine constructed and configured for automatic, continuous suturing for reduced or minimized scarring and reduced suturing time. A surgical suture module for continuous, subcuticular suturing. The module includes a generally circular needle with a needle shaft; a supply of thread; a cutting mechanism; a biasing member; a hook with a hook shank, a holding arm mechanism; and a housing. The needle, rotationally movable between a first position and a second position, is configured to introduce the thread into a tissue. The hook is operable for hooking and lifting the thread in coordination with the needle and the holding arm mechanism is operable for pushing and catching the thread in automatic coordination with the hook. The needle, the hook, and the holding arm mechanism are contained within the housing and the cutting mechanism is able to cut the thread after engagement of the biasing member.

Suturing loading unit

A suturing end effector includes a first jaw member, a second jaw member, and a helical needle. The first and second jaw members are moveable relative to one another between open and closed configurations. Each of the first and second jaw members defines a first row of wells that define a helical path when the first and second jaw members are in the closed configuration. The helical needle is rotatable through the helical path between retracted and extended positions. The helical needle is configured to draw a suture through tissue between the first and second jaw members when the helical needle is rotatably advanced through the helical path and configured to be independently moveable relative to the suture when retracted from the advanced position to the retracted position.

Methods of surgical fastening

An apparatus and a method for surgical fastening is disclosed. An illustrative apparatus for tissue suturing includes a cartridge having a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis, a reciprocating needle drive, and an actuator capable of releasably engaging the needle drive to rotate the needle. A method for suturing tissue is provided that includes placing a suturing device having a cartridge containing a suturing needle to span at least one tissue segment, activating an actuator to cause rotational movement of the suturing needle through the at least one tissue segment, and deactivating the actuator to stop an advancing movement of the suturing needle to cause a suturing material to be pulled through the at least one tissue segment forming a stitch.

Suture stitches for continuous surgical suturing

A device for making suture stitches for adjoining a first edge and a second edge of a tissue in an edge-to-edge interface. The device includes a handle and a device head. The handle including a motor for the device head and a means for attachment to the device head. The device head including a suture material supply; a needle rotationally movable, operable for moving the thread through a tissue; a hook operable for hooking and lifting the thread in automatic coordination with the needle; and a catcher operable for moving the thread into and out of the hook in automatic coordination with the hook.
