A surgical needle includes an elongated needle shaft and a needle head having a sharp point. A frangible neck, with a reduced cross-section, joins the needle shaft and the needle head and permits the needle head to be broken away from the needle shaft.

Surgical purse string suturing instrument and method

This invention relates to materials for medical or veterinary use that possess considerably improved properties with regard to friction. The invention also relates to the production of such materials from existing materials that possess suitable bulk properties, but inappropriate frictional properties. This invention also relates to a hydrophilic coating material that provides improved frictional properties.

Coating for tissue drag reduction

An endoscopic insertion device for inserting an anastomosis ring having two unitary members in an anatomic tubular body member comprises an anastomosis ring adapter for mounting the unitary members in an engaging position, an inserter for inserting the ring adapter in the tubular body member, and an actuator for actuating the adapter to close the anastomosis ring. A method of using the endoscopic insertion device includes the steps of inserting the anastomosis ring in an engaged position into the tubular body member, securing opposite ends of the tubular body member to the engaged anastomosis ring, applying a biasing force to close the anastomosis ring, releasing the biasing force, and axially withdrawing the insertion device from the closed anastomosis ring.

A purse string suturing instrument is provided for quickly and effectively forming a purse string suture in tubular tissue through relatively small cannulas placed in the body. The instrument includes a pair of elongated jaws, each having a row of spaced-apart uniform-size teeth. The jaws are hinged together at one end to clamp the tubular tissue therebetween. The two rows of teeth are offset with respect to each other so that they mesh when the jaws are closed. A single operating mechanism is provided to articulate the pair of jaws with respect to a longitudinal axis of the suturing instrument and actuate the jaws between an open position and a clamping position. The jaws are inserted through a cannula and positioned to close around the tissue to be sutured. The rows of teeth bend the tissue therebetween into a wavelike configuration. A pair of needles, the ends of each being connected to a single length of suture, is then inserted through passageways provided through the teeth. An encircling series of stitches are thus formed in the wall of the tubular tissue to create a purse string suture. The needles and the suturing instrument are then withdrawn through the cannula. The tubular tissue can be snugly fitted over an anastomosis ring or the like by drawing and tying the purse string suture.

A two-part ligation clip applicator comprises a handle assembly having a squeezable trigger and an elongated shaft connected at its proximal end to the handle assembly. The elongated shaft houses a sliding advancer which is actuated by squeezing the trigger to move axially in a forward direction in the shaft. In addition, a module is mountable at a distal end of the elongated shaft and supports a ligation clip. The module has a cartridge housing, latches pivotably mounted within the housing for gripping first part of the ligation clip, and a sliding pusher slidable within the housing by actuation of the advancer to engage the second part of the ligation clip and advance it relative to the first part to close the first part.

A transanal insertion device for surgically inserting an anastomosis ring having two unitary members into a tubular anatomic member comprises a distal adapter, a proximal adapter and an actuator. The distal adapter includes a hollow distal sleeve and a spring-loaded distal spool axially movable within the distal sleeve. The distal spool is biased in a first direction by a distal spring and includes alignment fingers pivotably connected thereon for aligning a first unitary member. The proximal adapter has a hollow proximal sleeve and a spring-loaded proximal spool axially movable within the proximal sleeve. The proximal spool is biased in a second direction by a proximal spring and includes alignment fingers connected thereon for aligning a second unitary member. The proximal member also includes a proximal gripper for securing the second unitary member on the proximal hollow sleeve. The actuator includes an elongated tube with a collar connected to its distal end and a handle assembly connected to its proximal end. First and second flexible rods connected to the handle assembly extend through the elongated tube. The flexible rods are manipulated to engage the distal adapter and draw it relative to the proximal adapter. The rods are also manipulated to release the distal and proximal adapters from their respective unitary members so the distal adapter, the proximal adapter and the actuator can be withdrawn transanally.
