A surgical instrument system comprising a first motor, a second motor, and a third motor is disclosed. The surgical instrument system comprises a first handle comprising a first number of controls, a second handle comprising a second number of controls, and a shaft assembly. The shaft assembly is attachable to the first handle in a first orientation in order to engage one of the motors. The shaft assembly is attachable to the second handle in a second orientation to engage a different motor. The surgical instrument system is configured to perform a different function of an end effector in the first orientation and the second orientation.

A medical instrument includes a hollow shaft (2) with a proximal end (3) connected to a handle (4) and a distal end (5) with a tool (6) arranged with one jaw part (8) pivotable relative to another jaw part (7). A distal end region of the shaft as a tool tip (10) deflects relative to a longitudinal axis (9) via an axially displaceable first actuation element (11) connected to the handle. The pivotable jaw part is adjustable via a second actuation element (13) mounted axially displaceably in the hollow shaft and connected to the handle. The first actuation element and the second actuation element are parallel to each other in the longitudinal axis direction of the shaft and mounted to be guided on each other. One of the two actuation elements is mounted on the inner side. The mutual axial mounting is effected via a pin-and-slot control (19).

An axis-aligning, force-limiting periarticular/intraarticular reduction forceps suitable for the reduction and realignment of specific anatomic structures includes a pair of medial and lateral forceps tines. A pair of tine tips may terminate the forceps tines, respectively. A pair of lateral and medial forceps handles may extend from the medial and lateral forceps tines, respectively. A first tine/handle junction may attach the lateral forceps handle to the medial forceps tine. A second tine/handle junction may attach the medial forceps handle to the lateral forceps tine. The second tine/handle junction may be pivotally attached to the first tine/handle junction. A force quantifying and limiting mechanism limits the magnitude of clamping force the medial and lateral forceps handles apply to the medial and lateral forceps tines. A pair of X-ray-visible targets on the medial and lateral tines assist with axis alignment for the insertion of fixation devices.

A medical or surgical instrument, preferably of the pincers, scissors and/or forceps design, includes at least two legs pivoted relative to each other in a pivoting plane and lockable in at least one pivoting direction and in at least one pivoting position. The legs include locking portions adapted to be brought into locking engagement with each other, with the locking portions offset against each other normal to the pivoting plane by such offset that, when the legs are pivoted in the pivoting plane, the locking portions laterally pass each other in the pivoting plane without getting into locking engagement with each other. The medical or surgical instrument is configured in such way that the locking engagement of the locking portions is implemented only by applying a transverse force normal to the pivoting plane to at least one of the legs while cancelling the lateral offset.

A forceps includes jaws, a first shaft having a first slot, a second shaft extending along the first shaft and having a second slot, and a rod that extends along the second shaft. The rod has a third slot including a locking portion and a guide track portion. A pin extends through the first slot, the second slot, and the third slot to prevent deployment of the rod when the pin is in the locking portion and to permit deployment of the rod when the pin is in the guide track portion. A first actuator produces relative movement of the first and second shafts to move the jaws relative to each other and move the pin from the locking portion to the guide track portion of the third slot. A second actuator produces movement of the rod to deploy the rod when the pin is in the guide track portion.

A surgical forceps including an end effector assembly has first and second jaw members. At least one of the first or second jaw members has a jaw frame defining a channel therein, an insulative member disposed within the channel of the jaw frame, and an electrically-conductive plate having a tissue contacting surface and at least one folded side portion. The insulative member includes a top portion having a tissue facing surface. The tissue contacting surface of the electrically-conductive plate is disposed on the tissue facing surface of the insulative member. The at least one folded side portion of the electrically-conductive plate is folded over the top portion of the insulative member such that the electrically-conductive plate conforms to a shape of the top portion of the insulative member.

Surgical delivery devices of the invention have a delivery shaft extending from a handle, with a deformable member such as a plate or a leaf at a distal portion of the shaft with a surface carrying an implant for orthopedic surgery. A trigger or lever on the device positions the deformable member between a first cylindrical configuration that can pass through a cannula used in arthroscopic surgery and a second, substantially flat configuration useful to place the implant on tissue during the arthroscopic surgery. Preferably the trigger may be operated to hold the deformable plate or leaf in any of a continuum of positions between the first cylindrical configuration and the second, substantially flat configuration.

A surgical instrument comprising two jaw portions, at least one of which is rotatably mounted via an axis of rotation at a distal end of a shaft and is connected via a traction cable or a push rod to a gripping portion at the proximal end of the shaft, wherein the jaw formed by the jaw portions is held in an open or closed position by means of a suspension when the instrument is at rest.

There is disclosed a system and methods for safely and securely gripping osseous-based tissue during allograft processing. One embodiment includes a first forceps half pivotally coupled to a second forceps half, where the first and the second forceps halves combine to form a handle portion and a head portion. The handle portion may define a first longitudinal axis, and the head portion may define a second longitudinal axis that intersects the first longitudinal axis at a varying head angle. The first and the second halves move between an open position in which the first and second forceps halves at the head portion are separated and a closed position in which the first and second forceps halves at the head portion are together. The forceps may also include an open-biasing spring element attached between the first and second forceps halves and a selective locking mechanism. Other embodiments are also disclosed.

A sensor system includes a first member that extends along a rotational axis and has a surface disposed circumferentially about the rotational axis. A conductive element is disposed on the surface of the first member and disposed about the rotational axis. A second member extends along the rotational axis. A rotational position between the first member and the second member is adjustable. A target is mounted to and rotatable with the second member and is movable relative to the second member between first and second positions. The target is spaced apart from the conductive element in both the first and second positions and is spaced further from the conductive element in the second position compared to the first position. The conductive element detects a change in movement of the target from the first position to the second position for any rotational position between the first member and the second member.
