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:
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:
Medical suturing devices, systems, and methods will be useful for endoscopic or open surgeries, including ear, nose, and throat procedures. Articulation motions may be transferred from a handle to needle grasping jaws using an axial movement of a shaft. Portions of the devices may be disposable, replaceable, and/or reusable, with different needle-grasping jaws and/or different elongate extension bodies having different configurations optionally being selectably coupleably to an articulatable handle and housing so as to allow the user to configure the device for a particular procedure.

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.
