A mechanism which is capable of anastomosis of two lumens by an absorbable fastener. The fastener is made from two washer-like plates. One such plate has holes to receive latching prongs protruding from the other plate. Fastening is done through a single linear motion that causes the prongs to pierce the tissue, latches the prongs into a receiver and causes a knife blade to cut through excess fastener material and tissue. The ease of removal, by pulling the mechanism through the formed anastomosis, is greatly enhanced. The system can be used such that the plates can be placed in any configuration to properly anastomose tissue.

A hemostatic clip for surgical use is disclosed having grooves on the inner surfaces of the legs which form an asterisk type pattern upon closure, knee bends in each leg which are opposed by notches or grooves that enhance the ability of the legs to fully straighten upon closure, and distal flat surfaces on the ends of the clip legs to prevent scissoring and ensure hemostasis when the clip is closed.

Surgical hemostatic clips

A hand-operated surgical instrument of closing wounds with a fastener. The instrument has a movable operating member extending from a movable handle which actuates the operating member. A hydraulic actuator comprising first and second cylinders is connected between the handle and the operating member for effecting the movement of the operating member when the handle is moved relative to the instrument. A biasing member is provided for returning the operating member and the handle means to the unactuated position. The surgical instrument includes a housing and a needle extending outwardly from one end of the housing. A plurality of fasteners are located within the housing such that when the operating member is actuated, the fasteners are forced out through the needle by the force of the operating member.

Surgical instrument with hydraulic actuator

A hand-operated surgical instrument for implanting a fastener in tissue to close a movable operating member remote from or extending from a movable handle for actuating the operating member. A hydraulic actuating means comprising first and second connected chambers oriented at angles relative to one another effect the movement of the operating member when the handle is moved relative to the instruments.

A ligating clip is provided with first and second legs joined at their proximal ends by a resilient hinge to define the rear end of the clip and spaced at their distal ends at the front of the clip with the legs having latch means at the distal ends for holding the clip closed in clamping engagement about tissue when the legs are squeezed together. The clip has a base extending along a portion of the first leg and the base terminates short of the distal end in a front face. Flanges are provided on a portion of the base and extend rearwardly from the front face and terminate short of the first leg proximal end. The flanges extend laterally outwardly beyond the sides of the first leg. The portion of the base that extends rearwardly from the flanges to the proximal end of the clip first leg has a width not greater than the width of the first leg.

Ligating clip with flanged base having a recessed engaging face

An instrument is provided for applying ligating clips seriatim and includes first and second handles mounted together for pivotal movement. Each handle extends beyond the pivot axis to form a clip closing jaw. The first handle includes a guideway for receiving a plurality of open clips. A pushing mechanism motivated by a serpentine spring is provided within the first handle to feed the clips to the jaw region. One of the jaws includes a lip for preventing discharge of the open front clip from the instrument. A mechanism is provided for at least temporarily maintaining the spring in a compressed position to permit loading of the instrument with clips and to permit transport and storage of the instrument without the feeding force acting on the clips.

An instrument is provided for applying a plurality of ligating clips seriatim and includes first and second handles mounted together for pivotal movement. Each handle extends beyond the pivot axis to form a clip closing jaw. The first handle includes a guideway for receiving a plurality of open clips. A pusher member is provided within the first handle to push the clips to the jaw region. An escapement member is mounted for pivotal movement within the first handle jaw and includes a forward protuberance and a rearward protuberance spaced from the forward protuberance. A rod is hingedly connected to the escapement member and extends rearwardly from the escapement member along the first handle. The rod is actuated by a cam on the second handle to pivot the escapement member to control the discharge of the clips from the jaws.

A tension spring concentric with the presser bar pulls the presser foot down against the work. The spring is threaded onto two holders, each of which fits around the presser bar. The first holder is attached to the presser bar near its upper end but the second allows the presser bar to slide within it. The second holder is slidably attached to a bracket and controlled by a presser bar pressure regulating cam to slide up and down in the bracket and thereby change the tension in the spring to exert a controlled force on the presser foot. The first holder is also slidably mounted in the bracket, and is controlled by a lever that has a lifting cam linked to the first holder. When the lever is lifted, the first holder is lifted to raise the presser bar and presser foot away from the work. This extends the spring, which urges the presser foot back down against the work as soon as the lever is lowered.

Presser bar biasing spring structure

A pneumatic needle threading assist is disclosed which has a thread collecting chamber in which, due to the air flow therethrough, thread having passed through the eye of a sewing needle, is therein deposited in a series of spiral loops limiting the amount of thread in the vacuum line and preventing the vacuum source from being contaminated with the thread.

Vacuum-type pneumatic needle threading assist

For a sewing machine, a needle mechanism selectively retractable to avoid penetration of a work material and to avoid faulty stitch placement. A hollow needle bar telescopically receives and supports in one end thereof a needle carrying mandrel. A flexible rod is carried internally of the needle bar; and is connected at one end to the mandrel, and at the other end to a plug slidably carried by the hollow interior of the needle bar and urged by a spring in a direction away from the mandrel. The flexible rod is formed with a first ear and a second ear, each ear extending laterally therefrom in opposite directions; and is fashioned with a bias to favor engagement of the first ear thereof with the end of a first slot in the hollow needle bar, so as to maintain the needle carried by the mandrel in a position to cooperate with a loop taker of the sewing machine in opposition to the urgings of the spring. Means are provided to deflect the flexible rod inwardly against the bias thereof so as to disengage the first ear of the flexible rod from the end of the first slot. The positioning of the first ear of the flexible rod on the inside diameter of the hollow needle bar will cause the second ear of the flexible rod to protrude through a second slot of the hollow needle bar provided therefor, and impinge on an end of the second slot to maintain the sewing needle in a non-cooperating position with respect to the sewing machine loop taker. A second means are provided to engage with the second ear of the flexible rod while the needle bar is moving upwardly, thereby to draw the flexible rod against the urging of the spring to a position where the first ear will reengage with the first slot in the hollow needle bar, thereby to reinitiate cooperation of the sewing needle with the loop taker of the sewing machine.

Retractable needle basting mechanism

This disclosure relates to a direct drive feed mechanism for sewing machines which is driven by an electronically controlled reversible electric motor and includes a linearly operable feed dog mechanism which is compact in structure and modular in nature. More particularly, the disclosure of this invention relates to a novel four motion feed mechanism for a sewing machine wherein reciprocating feed motion of the feed dog is initiated by a reversible electric motor which in turn is controlled by electronic logic means. Because of the novel structure of this invention, the feed of the fabric by the machine can be readily controlled so as to be capable of producing a plurality of programmed feed patterns.
