An organ retractor includes a plurality of retractor jaws, a central support structure, and a central housing. The central housing includes a threaded portion. The plurality of retractor jaws is hingedly connected to the central housing. The central support structure is coupled to the central housing. The plurality of retractor jaws is disposed in an open position by a spring.

An intra-abdominal liver retraction device and methods of use. The device includes a flexible sling, an anchor and a filament. The sling has a base edge and a pair of side edges tapering toward a leading edge. The sling also includes a stiffener extending across it adjacent the base edge to enable it to be gathered and inserted through a port into the abdomen, whereupon it can be opened. The anchor is configured to be releasably secured to the diaphragm with the base edge adjacent the diaphragm so that the liver can be disposed on the sling. The filament is connected to the sling adjacent the leading edge and configured to be drawn through an aperture in the abdominal wall to lift the sling with the liver thereon upwards.

A tissue retention belt for retracting and retaining tissue in a position that permits access to a body portion of a patient for a medical procedure includes a flexible elongate body, a gripping portion affixed to the elongate body at the intermediate portion, and at least one attachment surface disposed at a proximal portion and/or a distal portion of the elongate body. The elongate body may include a first material having a first coefficient of friction, and the gripping portion may include a non-adhesive second material having a second coefficient of friction greater than the first coefficient of friction and defining a slip resistant exterior gripping portion. The tissue retention belt can be positioned or wrapped around a patient's body (e.g., pannus, thigh) such that the gripping surface contacts and grips the patient's skin to retract and retain the skin at the position to provide access for a medical procedure.

Medical devices for use in the creation of a temporary pneumoperitoneum include a rigid dome, a sealing element, a retaining band, a septum, and a vacuum port. The rigid dome includes first and second dome sections. The first dome section engages with the second dome section to form the rigid dome. The retaining band applies a force to secure the first dome section relative to the second dome section. The sealing element seals the first and second dome sections. The septum engages at an aperture between the first and second dome sections. The vacuum port connects a vacuum source to the rigid dome to reduce a pressure on an interior of the rigid dome.

A retractor member includes a body portion extending along a longitudinal axis and being at least partially defined by a first lateral perimeter edge and a second lateral perimeter edge that each extends parallel to the longitudinal axis. The body portion additionally includes an upper surface and a lower surface that each extends between the first lateral perimeter edge and the second lateral perimeter edge. A first lateral support portion is coupled to the body portion at a first location at or adjacent to the first lateral perimeter edge, and a second lateral support portion is coupled to the body portion at a second location at or adjacent to the second lateral perimeter edge. A first coupling portion is disposed at a top end portion of the first lateral support portion and a second coupling portion is disposed at a top end portion of the second lateral support portion.

Systems and methods for minimally invasive computer-assisted telesurgery are described. For example, this disclosure describes cannula devices for use with computer-assisted teleoperated surgery systems. The cannula devices can facilitate enlargement of a minimally invasive surgical workspace by creating a tissue tent. The devices and methods described herein can be used in conjunction with computer-assisted teleoperated surgery systems that use either hardware-constrained remote centers of motion or software-constrained remote centers of motion.

The present disclosure relates to the field of tissue dissection. Specifically, the present disclosure relates to medical devices which lift and retract tissue during a dissection procedure to improve visualization of the target tissue and mitigate obstruction of dissection tools. In particular, the present disclosure relates to a tissue retraction device which moves from a constrained to relaxed configuration to immobilize and retract the dissected portion of target tissue during a dissection procedure.

A method of facilitating access to a neonate through a caesarean incision in the woman's abdomen by opening the incision, includes providing a supporting ring dimensioned to allow delivery of a neonate through the ring and comprising a non-adjustable pelvic-region retractor and handle fixed to the supporting ring and articulating the supporting ring to insert the non-adjustable pelvic-region retractor into the incision to cover and hold back the woman's bladder with the supporting ring disposed over the woman's abdomen. A first adjustable saddle-shaped retractor is then inserted into the incision to cup a first section of abdominal tissue on an abdominal side of the incision, before attaching the first adjustable saddle-shaped retractor to the supporting ring while it is cupping the first section of abdominal tissue at a first position spaced apart from the non-adjustable pelvic-region retractor to anchor the supporting ring to the woman and partially open the incision.
