摘要:
A surgical needle is adapted for use with a circular needle applier having a needle driver. The surgical needle comprises an elongate body curved along a circular arc in a plane. The elongate body has a leading end, a trailing end, a longitudinal axis between the leading and trailing ends, a cross-sectional circumference, an upper face, a lower face, a medial face, and a lateral face. A pair of recessed features on the body are adapted to be engaged by a needle driver. A pair of protuberances are adjacent each recessed feature. The protuberances are longitudinally coincident with the respective recessed feature and circumferentially offset from the respective recessed feature. The protuberances project outwardly from the body.

Various exemplary methods, systems, and devices for surgical suturing are provided. In general, a loading element can be configured to facilitate loading of a plate into a surgical instrument configured to facilitate passage of a suture through tissue. The surgical instrument can be configured to advance the suture through a tissue of a patient, to capture a free end or looped end of the suture after the suture's advancement through the tissue, and to pull the captured suture out of the patient's body with a portion of the suture remaining passed through the tissue within the patient's body.

A suturing apparatus comprises a pair of jaws. A bendable needle housed in one of the jaws is adapted to carry a suture. An optional suture receiver may be disposed adjacent to the opposite jaw. A transition block curves the needle and directs it in a direction generally unparallel to an axis of the carrying jaw. The needle may also be configured to retrieve a suture. A retaining mechanism holds a suture in place to be engaged by the needle. The jaw housing the needle may include a lateral opening through which the suture may be inserted. The needle may also include a lateral notch which may be aligned with lateral opening to receive the suture. An actuator coupled to the needle enables the user to move the needle proximally to align the notch with the lateral slot.

A suture passing device includes a notchless tubular needle having a preformed curved shape. One or more cleats are disposed within the needle to help secure suture engaged by the sharp distal tip of the needle and to prevent further bifurcation of the suture. The deformable needle is housed in a channel of a lower jaw having a curved guidepath that approximates the curved geometry of the preformed needle, thereby facilitating the consistent return of the needle to its preformed shape each time the needle exits the channel. A dual needle suture passing device is also provided having a second notchless needle to enable a mattress stitch. Methods of loading a suture onto a notchless needle in a suture passer are also provided.

An implant manipulator may have a distal end that retains an implant, a proximal end, and an intermediate portion between the ends. The intermediate portion may have a cross-sectional shape that extends along a nonlinear pathway. The intermediate portion may have a selectively bendable portion in which the cross-sectional shape varies to facilitate bending when desired. The implant manipulator may be a needle for a suture passer, with a suture capture feature at the distal end. The suture capture feature may have first and second members that flex apart to permit entry of the suture into a suture capture hole wherein the suture is retained until released. A suture passer may receive the needle in a bore shaped to change the cross-sectional shape to facilitate or restrict bending of the needle, as needed.

An arthroscopic meniscal tear repair device includes a catch needle and a transfer needle. which are pierced into a torn meniscus and advanced past the tear. Suture is transferred by a suture needle from the transfer needle through the meniscus and into the catch needle. The catch needle has an internal mechanism that retains the suture. The suture needle is then retracted back to its home position inside the transfer needle, leaving the free end of the suture across the meniscus and in the catch needle. The device is then retracted out of the meniscus, leaving behind a stitch across the meniscal tear inside the meniscus . A pre-tied knot of suture is then slid down the device and cinched up using a knot pusher having a dilation tip, thus completing the repair.
