The invention discloses an in vivo organ transfer device, which comprises an organ fixing bag and an organ bag push assembly, wherein the organ fixing bag is composed of an inner bag and an outer bag, the outer bag is provided with an ice water filling hole and a link rod fixing interfaces, multiple groups of link rod fixing interfaces are arranged on both sides of the outer bag, and the inner layer bag is provided with an organ inlet, an input conduit opening and an output conduit opening. The invention belongs to the technical field of in vivo organ transfer, in particular relates to an in vivo organ transfer device that can provide good temperature conditions in the organ implantation process and it can fix the transplant in the reconstruction process to make the transplant in the optimum location and angle most conducive to the conduit suturing, creating favorable conditions for minimally invasive organ transplantation.

Described herein are various method of using a direct drive system to perform procedures at a distance. One exemplary method include tying a knot or suturing at a distance with a first and second end effector. The direct drive system can enable sufficient end effector dexterity, including the ability to control various degrees of freedom of end effector movement, and allow a user to perform complicated task at a distance. In one aspect the direct drive system includes flexible tools that permit access to surgical site via a natural orifice.

A tissue retrieval system including a tissue retrieval bag deployable from an introducer and suspended in an open configuration by support arms can include retention features to prevent inadvertent movement of the tissue retrieval bag relative to the support arms. The support arms can include protruding domes, folds, or curls to restrict sliding of the tissue retrieval bag relative to the support arms. Alternately, tension can be maintained in a cord loop coupled to an opening of the tissue retrieval bag to prevent the tissue retrieval bag from inadvertently sliding relative to the support arms.

Disclosed is a specimen retrieval device that utilizes a constricting mesh to assist with the contained retrieval of specimens during minimally invasive surgical procedures. The device can facilitate isolation and removal of specimens and allows the specimen to be removed through a smaller incision than a traditional extraction bag through constricting and elongating of the specimen by tension provided from pulling the specimen retrieval device and activating the inner woven fibers. The two-hole opening allows for optimal specimen orientation. In certain aspects the device is configured to disperse pulling tension over a larger area reducing the likelihood of specimen tearing during removal. Large specimens are safely reduced to an easily removable size and shape.

Specimen retrieval bags, specimen retrieval devices, specimen retrieval systems, and specimen retrieval methods that are configured to facilitate the isolated removal of a tissue specimen from an internal body cavity such as, for example, during a minimally invasive surgical procedure.

A tissue specimen retrieval device includes a housing, an outer shaft extending distally from the housing, an end effector assembly extending distally from the outer shaft in a deployed position, a tissue specimen bag supported on the end effector assembly and including an open end extending between proximal and distal end portions of the end effector assembly, a cinch loop disposed about the open end of the tissue specimen bag, and a distal cinch tab. The distal cinch tab is disposed at the distal end portion of the end effector assembly and extends from the open end of the tissue specimen bag. The distal cinch tab is operably coupled to the cinch loop such that pulling the distal cinch tab distally relative to the cinch loop constricts the cinch loop about the open end of the tissue specimen bag to cinch the open end of the tissue specimen bag closed.

A medical net-and-loop type retrieval instrument has a distal loop and a retrieval net held on the loop by way of a net holding portion that is firmly held in the interior of the cross section of the loop. The medical net-and-loop type retrieval instrument is suitable for use in medical endoscopy.

A system includes an access cannula, a deployment cannula having a plurality of engagement arms, and a containment bag. The deployment cannula is slidable within the access cannula between an initial condition, wherein the engagement arms are retained in a contracted configuration, and a deployed condition, wherein the engagement arms are disposed in an expanded configuration. The containment bag includes an open end portion configured to receive the first elongated tubular member and the second elongated tubular member. In the initial condition, a portion of the containment bag towards the open end portion is positioned adjacent at least one of the first elongated tubular member or the second elongated tubular member. In the deployed condition, the portion of the containment bag is expanded such that the portion of the containment bag is spaced-apart from the at least one of the first elongated tubular member or the second elongated tubular member.

A tissue specimen retrieval device includes a first shaft having a pair of slots defined in a distal end thereof and a pair of windows defined proximally of the pair of respective slots. A second shaft is included having a bag brim attached thereto, the second shaft telescopically movable within the first shaft between a retracted position, wherein the bag brim is disposed within the first shaft and a partially deployed position wherein the bag brim partially deploys from the first shaft forming an enclosure for supporting the tissue bag thereon. A pair of hook members is included each having an arm, a first end engaged to the bag brim and a free end including a hook at a distal end thereof. Upon deployment, the hook of each hook member engages a respective window allowing each respective arm to pivot outwardly within respective slots to fully deploy the bag brim.

A specimen retrieval device includes outer and inner shafts. An end effector is supported on a distal end of the inner shaft and includes first and second arms that are configured to support a specimen bag. The first and second arms are movable via actuation of a handle between a proximal position wherein the first and second arms are retracted and a distal positon wherein the first and second arms are deployed and the specimen bag is positioned for receiving tissue. A release tube is disposed within a collar defined in the specimen bag and is configured to releasably engage respective first and second arms to provide stability when supporting the specimen bag and facilitate disengagement of the first and second arms from within the collar upon retraction of the first and second arms.
