Methods and devices are provided for performing minimally invasive surgical procedures. In one embodiment, a surgical device is provided that includes an elongate shaft having a distal portion configured to be movable between a first configuration in which the distal portion of the shaft is substantially straight or linear and a second configuration in which the distal portion of the shaft is bent at a compound angle. The shaft's distal portion can be configured to be articulated in a wide range of compound angles and can be configured to be selectively locked in a fixed position anywhere within that range.

An apparatus maintains the sterility of a medical device while providing for the insertion of an insertable component into the medical device. The apparatus includes a medical device having a housing sized to contain the insertable component, an active feature, a cap, and a hinge member. A container encases the medical device within a device recess, a cap recess, and a container cover. The insertable component may be inserted into the housing while limiting potential contact with the exterior of the medical device. An alternative assembly comprises an insertion assembly having a handle and the insertable component detachably attached thereto. The medical device comprises a housing, an active feature, and a flexible member. An insertion tube is insertable within the flexible member to limit contact when the insertable component is inserted into the housing. Yet another configuration includes a resiliently hinged door assembly releasable by a release button.

摘要:
A method for treating obesity by reducing the volume and/or alter the functioning of the gastric cavity to limit food consumption and induce early satiety. The method includes accessing the cavity endoscopically to visualize the interior of the cavity. The peritoneal cavity is accessed through a small incision in the abdominal wall. Using endoscopic visualization, suture anchoring devices are introduced into the peritoneal cavity through the incision and deployed from the exterior surface through the gastric cavity wall. Suture from pairs of the anchoring devices is drawn through the gastric cavity wall and tightened outside of the cavity to form a serosa to serosa plication. Any number of plications may be formed in the cavity wall and the contacting tissue within a plication may be treated to promote healing and a more durable bond.
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 fastener applying device including 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 also 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 also includes an adjustment nut connecting the staple housing to the handle. Rotation of the adjustment nut changes the distance.

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:
Methods and devices are provided for controlling movement of a distal end of a surgical instrument. In general, the methods and devices can allow for controlling movement of surgical tools, and in particular for causing mimicked motion between an external control unit and a surgical tool positioned within a patient's body. In one embodiment, a surgical system is provided having a master assembly including an input tool and a slave assembly including a surgical instrument. The master assembly and the slave assembly can be configured to be electronically coupled together such that movement of the master assembly can be electronically communicated to the slave assembly to cause mimicked movement of the slave assembly.
