摘要:
Various embodiments of spacer apparatuses, and transport and/or storage apparatuses, for use with magnetic platforms configured to be magnetically coupled to a medical device within a body cavity of a patient.
摘要:
An introducer for an internal magnetic camera is provided. The introducer may be arranged to enable the camera to be placed inside of a body cavity through an otomy or incision and then oriented next to the tissue of the body cavity opposite an External Control Unit (“ECU”) outside of the body cavity. The camera may be retained in the introducer by a magnet or a magnetic material, by a selectively engageable retainer, or by covering the camera within a cavity. The camera may be retained in the introducer by a latch. The camera may include a keyed surface that only can align with a matching keyed surface on the retainer in a single orientation. The introducer may include a spring to eject the camera from the introducer when the retainer is disengaged.

A tissue retrieval device includes an introducer tube and a tissue retrieval bag. The introducer tube is insertable into a patient through a trocar. The bag may be selectively exposed at the distal end of the introducer tube, receive a tissue specimen, and be withdrawn from the patient. The bag includes a plurality of folds allowing the bag to transition from a folded configuration to an unfolded configuration. The folds may extend along a length of the bag transverse to the introducer tube; or along a length of the bag parallel to the introducer tube. The folds may extend about a perimeter of the bag, such as a circumference of the bag, and may be spaced apart along a length of the bag transverse to the introducer tube. The folds may be formed by petals that provide the bag with a generally spherical configuration when the bag is unfolded.
摘要:
The device includes an elongate shaft having a distal end coupled to a proximal end of an articulation joint, and an actuation wire extending through the elongate shaft and the articulation joint. The device includes an end effector having a distal tip coupled to a distal end of the articulation joint and receiving therethrough a distal end of the actuation wire. The end effector includes a hook knife disposed adjacent the distal tip and having a proximal end connected to the distal end of the actuation wire. The actuation wire is translatable along a longitudinal axis of the elongate shaft to extend and retract the distal end of the hook knife relative to the distal tip of the end effector, and the articulation joint is laterally articulatable relative to the longitudinal axis of the elongate shaft to allow the end effector to be angularly oriented relative to the elongate shaft.
摘要:
Methods and devices are provided for controlling movement of a working end of a surgical device, and in particular for performing various surgical procedures using an instrument having an end effector that can be articulated relative to an elongate shaft of the device. In certain embodiments, the end effector can also optionally rotate relative to the elongate shaft of the device, and/or the shaft can rotate relative to a handle of the device.
摘要:
A single port surgical method comprises inserting only a single trocar through the abdominal wall; inserting a camera into the abdominal cavity; magnetically anchoring the camera to the abdominal wall; obtaining a first instrument comprising an elongate shaft with a distal end and a proximal end connected to a first handle; passing the distal end of the first instrument through the abdominal wall independent of a trocar; attaching in vivo an end effector to the distal end of the first surgical instrument; obtaining a second instrument comprising an elongate shaft with a distal end with an end effector and a proximal end connected to a second handle; passing the distal end of the second instrument through the trocar; and manipulating tissue in the abdominal cavity with the first and second surgical instrument end effectors under visualization from the magnetically anchored camera.
摘要:
Methods and devices create an intestinal braking effect, are non-invasive or minimally invasive, and may be reversible. These methods and devices are accomplished via stabilized implantable systems, and ingestible pills. In one embodiment, the implantable system comprises a device delivering a therapeutic substance to a target location within the gastrointestinal tract of a patient in order to initiate an intestinal braking effect which would promote sensations of satiety and stimulate excess weight loss for the patient.
摘要:
A dicing device dices tissue harvested from a patient. The dicing device comprises a grid cutting element and a tray to receive diced tissue. The dicing device may be integrated into an otherwise conventional biopsy device. The diced tissue specimens may be further processed, such as by being introduced into a self-expanding fistula plug creation and delivery system. The self-expanding fistula plug creation and delivery system comprises a sheet and a reinforcement tube. A scaffold material may be placed in the sheet, which may then be folded and reinforced, with the scaffold material being compressed in the sheet. The scaffold material may then be pushed into a catheter end. The catheter end may be inserted in a fistula. The scaffold material may then be flushed with a cell matrix that is based on the diced tissue to create a fistula plug, which may be left in the fistula.
摘要:
A surgical device for use in combination with a percutaneous elongate shaft defining a longitudinal axis. The shaft comprises a distal end and a proximal end, the distal end comprising an attachment mechanism. A surgical end effector is selectively attachable in vivo and detachable in vivo to the attachment mechanism of the percutaneous elongate shaft. A percutaneous elongate loader comprises an articulating distal end. The distal end comprises a tube with an opening at the distal tip, the tube being dimensioned to receive the surgical end effector. The distal end further comprises an engagement feature capable of frictionally holding the surgical end effector in the tube during in vivo attachment to and in vivo detachment from the percutaneous elongate shaft.
