摘要:
A surgical fastener applying device having a handle with a trigger pivotably attached thereto and movable within a trigger plane. The trigger has a bottom portion extending from the handle and a top portion disposed within a housing of the handle. The device has a staple housing with a proximal end attached to the handle, a distal end extending therefrom and a longitudinal axis therebetween. The housing has a firing bar disposed within, and the trigger is coupled to the firing bar. The device has a link member with a first end pivotably attached to the top portion of trigger, the link member has a second end comprising a slidable pin. The pin engages a three dimensional cam path disposed within the housing. The link member follows distal and proximal movement of the top portion of the trigger, and the pin slides perpendicular to the trigger plane to follow the three dimensional cam path.
摘要:
A method for deploying fasteners including the steps of providing a device having a handle and at least one actuator. The handle is connected to an elongated hollow housing having distal and proximal ends. The device has a first cartridge containing at least one fastener releasably connectable to the handle and an elongated pusher movable through the hollow housing from the distal to the proximal end for deploying the fastener from the distal end. The method includes increasing the stiffness of the pusher at a distal end thereof and advancing the pusher through the elongated housing to deploy the fasteners.
摘要:
A method of deploying a surgical fastener including the step of introducing the fastener into a body of a patient while the fastener is in a first shape having a first loop with a back span and an original size and shape. The method involves moving the end segments of the fastener in a first manner away from each other while maintaining the fastener in a closed loop. The method also involves moving the end segments of the fastener in a second manner away from each other to open the loop. The method further involves forming the fastener into a second loop having a width greater than the width of the first loop.
摘要:
A fastener applying device for surgically attaching tissue together. The device includes a staple housing having a proximal end attached to a handle, a distal end and a longitudinal axis therebetween. There is at least one fastener within the housing. The device includes an anvil movable within the staple housing. The anvil has a proximal position and a distal position, wherein when in the distal position a distal end of the anvil extends distal to the distal end of the staple housing by a distance. The device further includes an adjustment nut connecting the staple housing to the handle, wherein rotation of the adjustment nut changes the distance.
摘要:
A mechanism for feeding a fastener including a housing having a longitudinal axis and at least one fastener within the housing. The fastener has a crown and at least two legs extending therefrom. The fastener is disposed within the housing in a first plane parallel to the longitudinal axis. The mechanism includes an elongated actuator disposed within the housing. The actuator has a shaft substantially parallel to the longitudinal axis of the mechanism and rigidly spaced from the fastener in a second plane. The actuator has at least one radially extending advancer disposed along a length thereof, and a mechanism for rotating the actuator so that the advancer engages the fastener.

摘要:
A surgical fastener applier having a handle and a fastener housing extending from the handle. The housing contains at least one anvil movable within the staple housing, the anvil has a proximal position and a distal position. When in the distal position a distal end of the anvil extends distal to the distal end of the staple housing. The housing contains a plurality of surgical fasteners each of which in the shape of a loop. At least one of the fasteners is placed around a portion of the anvil when in the distal position. The applier has a first mechanism for moving the anvil distally after a fastener has been deployed, and a second mechanism for moving the anvil distally after a fastener has been deployed. The second means is independent of the first means.
摘要:
A method of attaching a knotting element to a suturing device including the steps of providing an adapter for insertion into a body, the adapter having a proximal end and an open distal end. Providing a knot tying element for tying suture together. Releasably attaching the distal end of the adapter to the knot tying element by inserting a proximal end of the knot tying element into the open distal end of the adapter and thereafter rotating the knot tying device with respect to the adapter.
摘要:
A suture locking device including an adapter for insertion into a body. The adapter has a proximal end, an open distal end and a lip within the distal end projecting towards an interior of the open distal end. The device further includes a knot tying element releasably attached to the distal end of the adapter. The knot tying element has a distal and a proximal end. The proximal end of the knot tying element has a recess thereon. The proximal end of the knot tying element is inserted within the open distal end of the adapter such that the lip and the recess mate with each other to form a releasable lock.
