摘要： Improved medical suturing devices, systems, and methods for loading a needle in a suturing device, particularly standard surgical needles. An exemplary device includes a body having one or more clamps for grasping a needle and a needle loader supporting the needle in a delivery position suitable for advancing through a minimally invasive aperture and a needle loading position suitable for grasping with a clamp of the device. Preferably, the needle loader includes an elongate body having a rotatable needle holding member and is releasably coupleable with the device body such that the needle is moveable between positions from a proximal portion of the device. Methods includes selecting a standard surgical needle, advancing the needle loader device into a body of a patient, and moving the needle to a needle loading position for grasping and suturing with one or more clamps of the device.

摘要： Improved medical suturing devices, systems, and methods for maintaining a position and orientation of a suture needle at a fixed location relative to a suturing device. An exemplary device include a clamp having opposing grasping surfaces for grasping the needle at a first location, and a needle contacting surface for contacting the needle at a second location, the second location a distance axially away from the first location so as to inhibit unintended movement of the needle relative to the device, which may include rotation of the needle about the first location and rotation of the needle about its axis. In many embodiments, the device includes a first and second clamp and a mechanism for alternating grasping of the needle between the first and second clamp. The device may also be incorporated into a single-clamp needle grasping device.

摘要： Improved medical suturing devices, systems, and methods may hold a suture needle at a fixed location relative to a handle of the device, allowing the surgeon to grasp and manipulate the handle of the suturing device to insert the needle through tissues in a manner analogous to use of a standard needle gripper. Cycling the handle from a closed position to an open position and back to the closed position may alternate the device between gripping the needle with a first clamp (for example, along a proximal portion of the needle) to gripping the needle with a second clamp (for example, along a distal portion of the needle) and optionally back to gripping with the first clamp, with the needle often staying at a substantially fixed location relative to the altering device body. Related single-clamp needle grasping devices can be bent plastically by a surgeon, and/or have bodies that are grasped by a hand while a portion of the hand actuates a handle.

摘要： A retractor system includes one or more blades, a handle, and a frame. The handle includes first and second arms with jaw portions and recesses configured to removably retain a blade. Both arms include rotatable connections and handles, where the rotatable connections are between jaw portions and handles. The rotatable connections are connected together such that the arms are rotatable with respect to one another. In one embodiment, the recesses are partial disc shapes opposed to one another, such that when the jaw portions are in a closed position, a disc-shaped space is present between the jaw portions in the closed position. The blade includes a corresponding disc-shape protrusion that may be retained in the recesses, and in some embodiments may include one or more notches to mate with a protrusion in a recess that prevents blade rotation while in the handle.
