Multi-mode torque drivers employing anti-backdrive units for managing pedicle screw attachments with vertebrae, and related systems and methods are disclosed. A spinal column includes vertebrae in an articulating structure protecting a spinal cord. Medical intervention may involve limiting the relative motion between vertebrae by fusing vertebrae together with mechanical assemblies, including pedicle screws attached to the vertebrae. A torque driver may be used to form the pedicle screw attachments with vertebrae. By including an anti-backdrive unit and a motor assembly enclosed within a handle body as part of a multi-mode torque driver, the user may apply sequential combinations of manual and motorized torques to the screws with high levels of tactile feedback as desired. In this manner, pedicle screw attachments may be efficiently achieved with fewer injuries to the patient and surgeon while minimizing screw attachment failures.

A modular shaft assembly is disclosed. The modular shaft assembly includes one or more inputs configured to receive input motions from a surgical instrument system, such as a handle, for example. The shaft assembly further includes one or more on-board inputs configured to generate input motions. The input motions received and generated by the shaft assembly are transferable to an end effector of the shaft assembly to perform various functions at the end effector. The end effector can include a staple cartridge and a firing member which is movable between a proximal position and a distal position to eject staples from the staple cartridge. The end effector can include a plurality of jaw members and the firing member can comprise camming members which are configured to position the jaw members relative to one another.

According to some embodiments, systems and methods are provided for non-invasively detecting the force generated by a non-invasively adjustable implantable medical device and/or a change in dimension of a non-invasively adjustable implantable medical device. Some of the systems include a non-invasively adjustable implant, which includes a driven magnet, and an external adjustment device, which includes one or more driving magnets and one or more Hall effect sensors. The Hall effect sensors of the external adjustment device are configured to detect changes in the magnetic field between the driven magnet of the non-invasively adjustable implant and the driving magnet(s) of the external adjustment device. Changes in the magnetic fields may be used to calculate the force generated by and/or a change in dimension of the non-invasively adjustable implantable medical device.

A compression force magnifier comprising: an engaging surface for attaching to a bone plate; a ramped component above the engaging surface, the ramped component having a bottom surface adjacent the engaging surface and an angled upper surface; and a hole extending through the ramped component and the engaging surface.

The invention concerns a surgical drill bit able to be connected to a surgical tool, comprising a flexible stem. The invention also concerns a corresponding method to produce the surgical drill bit.

An Example tool for implanting a pacemaker lead includes a body that includes a recess, a first electrical contact positioned within the recess, and a projection coupled to the body. In addition, the tool includes a second electrical contact positioned on the projection. The recess is configured to receive the pacemaker lead therein such that a first electrode of the pacemaker lead is to engage with the first electrical contact and a second electrode of the pacemaker lead is to engage with the second electrical contact. A rotation of the tool about a central axis of the pacemaker lead is configured to rotate the first electrical contact and the first electrode together about the central axis and to slidingly engage the second electrical contact along the second electrode

A surgical instrument access port assembly and method of use is disclosed. A locking mechanism includes a lock base having an aperture that receives the surgical access port. A locking member has an opening that receives the surgical access port. A ball having a lateral slit is received between the lock base and the locking member. The locking member is rotatable relative to the lock base into a locked position to secure the surgical access port with the ball when the surgical access port is inserted into fascia, and the locking member compresses the lateral slit in the locked position.

An organization device for maintaining a suspensory graft fixation device (i.e., an implant and suture) in a desired position. The device includes a substrate having top and bottom edges with first and second panels extending therebetween. The device also includes a first central longitudinal axis extending in a direction from the top edge to the bottom edge between the first and second panels. The first and second panels are foldable about the axis between open and closed positions. The device also includes an opening extending through the bottom edge and into the first panel, and a plurality of top slits and bottom slits. The plurality of top slits includes at least one top slit which is aligned with the first opening. The device additionally includes a tabs adjacent the opening. The slits and tabs are configured to maintain suture of a suspensory graft fixation device in an organized manner.

A single-use handle is configured to attach to a working shaft that can support a sounder for measuring the medullary canal of a proximal radius, and a planarizer that is configured to planarize a proximal edge of the proximal radius after the proximal radius has been resected. The handle can further include a plurality of sizing cavities that are configured to receive the resected bone so as to determine the size of the resected bone. The handle can further include an ejector that is configured to decouple the planarizer from the working shaft.

A stapling assembly configured to produce staples having different formed configurations is disclosed.
