摘要:
Various exemplary methods and devices are provided for manipulating and/or anchoring devices and body parts during surgical procedures. In one embodiment, an anchor member is provided for anchoring a device or body part to tissue, such as an internal wall of a body cavity. The device can be, for example, an endoscopic device, an accessory channel coupled to an endoscopic device, or a support member adapted to support or manipulate an organ. The anchor member can include or form an opening through which the device can be inserted. The anchor member or device can thus be manipulated relative to the tissue to control movement of and/or provide support to the device, tools inserted through the device, and/or organs grasped by the device or tools.

Various surgical devices, kits, and/or methods are provided herein that may be useful in performing a surgical procedure through a natural orifice. Such a surgical procedure may utilize one or more devices, kits, and/or methods to create an access port to a body cavity of a patient, to perform a specific surgical procedure, and to close the access port. In various embodiments, the specific surgical procedure may comprise a sleeve gastrectomy, a ventral hernia repair, a hybrid transgastric cholecystectomy, and/or a hybrid transgastric appendectomy.

A positionable imaging device includes a body defining a first end and a second end. The body is configured to be received within an internal body cavity. An imaging device is located at the first end of the body. A releasable fastener is coupled to the body to removably attach the imaging device to tissue within the internal body cavity. A release mechanism is coupled to the releasable fastener to detach the imaging device from the tissue.

A surgical device comprises an ex vivo magnet and an in vivo sled magnetically attracted to the ex vivo magnet. The sled can be positioned and anchored within a patient by moving the ex vivo magnet. The sled defines a longitudinal axis. An arm extends from the sled. The arm is moveable relative the sled between a retracted position and an extended position. The arm comprises an end effector. A locking mechanism operatively connected to the arm to lock the arm in the retracted and extended positions. The mechanism may include a rack that both rotates about a pinion and translates tangentially about the pinion.

Various embodiments of an elongate surgical device configured to travel along a tortuous body lumen to a surgical site are provided herein. In one embodiment, the device can include a tensioning element extending through a channel formed along a length of the device and the tensioning element can translate an articulation force to the working end of the device. During such articulation of the device, a portion of the channel can be configured to allow the tensioning element to exit the channel and move away from a longitudinal axis of the device thereby optimizing a mechanical advantage relative to the distal end of the device and thus maximizing the force capable of being delivered thereto. Additionally, various embodiments of a method for articulating a working end of an elongate surgical device are provided herein.

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.

Methods for stabilizing and positioning an endoscope using various braided devices and suture techniques. Related endoscopic surgical procedures are also disclosed.
摘要:
A surgical kit comprises two percutaneous instruments each having an elongate shaft with a distal end and a proximal end connected to a handle; at least two end effectors attachable and detachable to the distal ends of the percutaneous instruments; a laparoscopic loader adapted to receive the end effectors; a trocar; and a laparoscopic surgical stapler. The surgical kit may further comprise laparoscopic energy based clamping and coagulating device and/or a laparoscopic suture device. Optionally, the surgical kit may further comprised a third percutaneous instrument having an elongate shaft with a distal end and a proximal end connected to a handle, and at least three end effectors attachable and detachable to the distal ends of the percutaneous instruments. The surgical kit may further comprise a magnetic camera and/or a magnetic external control unit adapted to anchor a magnetic camera. The components of the surgical kit may be contained in a sterile sealed package.
