  • Patent number: 11123093
    Abstract: A surgical instrument includes an elongated body operably connected to a jaw member and a blade. The elongated body includes an inner tube and an outer tube configured to move laterally with respect to one another. A drive arm has a first end engaged to the outer tube and a second end pivotably coupled to the jaw member configured to move laterally in tandem with the outer tube such that motion of the outer tube in a first direction pulls the jaw member away from the blade, and motion of the outer tube in a second direction pushes the jaw member towards the blade. The drive arm includes a semi-rigid material configured to flex when compressed, such that flexion of the drive arm can offload excess force exerted by the outer tube on the jaw member.

  • Patent number: 11083453
    Abstract: A surgical instrument that includes an elongate channel that is configured to operably support a surgical staple cartridge therein. In at least one form, an anvil is pivotally coupled to a proximal end of the elongate channel such that the anvil is pivotal about a discrete, non-movable anvil axis defined by the elongate channel. A firing member is configured for axial travel within the elongate channel in response to an application of firing motions thereto. The firing member is configured to movably engage the anvil and the elongate channel to space the anvil relative to the elongate channel at a desired spacing as the firing member is axially driven through the elongate channel. A closure member is configured to move the anvil from an open position to closed positions relative to the elongate channel upon application of closure motions to the closure member.

  • Patent number: 11045331
    Abstract: Implant inserters and related methods are disclosed herein, e.g., for delivering a fusion cage or other implant to a spinal disc space and for rotating or articulating the implant within the disc space. An exemplary instrument can include an inner member having opposed jaws for grasping the implant and holding the implant during insertion. The inner member can be slidably received within an outer member such that relative axial translation of the inner and outer members is effective to open or close the jaws. The jaws and/or the distal end of the outer member can have a low-profile geometry, which can advantageously facilitate certain surgical procedures. For example, the low-profile geometry can allow for a more medial approach to an intervertebral disc space in which the implant is to be inserted.

  • Patent number: 11045212
    Abstract: An instrument for drilling a hole for a bone screw comprises a shaft having a primary drill fluted portion, a shank, and a middle portion there between. Part of an outer surface of the shaft's middle portion is non-curved. A sleeve surrounds the shaft. The sleeve has an inner surface that is complementary to the outer surface of the shaft's middle portion such that the sleeve slides with respect to the shaft. The sleeve's inner surface contacts the outer surface of the shaft's middle portion at the non-curved part such that the shaft can transmit torque to the sleeve. A countersink drill bit is provided at an end of the sleeve proximate the shaft's primary drill fluted portion. A locking mechanism selectively holds the sleeve in a fixed position with respect to the shaft, locating the countersink drill bit at a selected position with respect to the shaft's drilling end.
