A single use integrated disposable rotational speed reduction assembly having a shaft assembly, a housing, an output assembly, and a plurality of planetary gears each having a plurality of gear teeth. The shaft assembly is configured to cause rotation of the planetary gears with a sun gear. The rotation of the planetary gears is configured to cause rotation of an output shaft, with a reduction of rotational speed relative to the rotation of the shaft assembly. One or more gear components or spacers can be configured to fail after a predetermined number of use cycles.

Staple cartridge assemblies for use with surgical stapling instruments and methods for manufacturing the same are provided. Scaffolds for use with a surgical staple cartridge and methods for manufacturing the same are also provided.

A ligation device that includes a clip device including an openable arm, a connector connected to the clip device and is able to be released from the connector, a wire connected to the connector and configured to operate the clip device, and a pipe including an opening into which the wire is inserted. An inner diameter of the opening is smaller than a dimension in a diameter direction of the connector in a first state in which the connector and the clip device are connected with each other, and the inner diameter of the opening decreases towards a proximal end side of the pipe and is larger than the dimension of the connector in a second state in which the connector and the clip device are unconnected with each other.

A stapling device includes an adapter assembly and a reload assembly that includes a reload release mechanism that is movable from a locked position in which the reload assembly is locked onto the adapter assembly to an unlocked position in which the reload assembly can be removed from the adapter assembly. The adapter assembly of the stapling device includes a lockout that prevents movement of the reload release mechanism to the unlocked position unless the stapling device is in a non-articulated, unfired position.

The present invention provides a supporting hook structure, comprising a sleeve, a fixing rod, a first limit unit, a hook and a fixing device. The fixing rod is connected to the side surface of the sleeve. The hook body is connected to one end of the sleeve. The first limit unit is arranged on the side surface of the sleeve and adjacent to the hook body. The first limit unit makes the hook body rotates with the axis direction of the sleeve as a rotation axis. The fixing device is connected to the other end of the sleeve to fix the rotating position of the hook body. Through the above, the hook part enters the proximal thigh from a surgical entrance and the hook part rotates to make the hook part abut against the proximal femur to complete the positioning and fixation of the femur hook structure to the femur.

Systems and method of using a surgical driver instrument are provided. The driver instrument includes a driver shank having a proximal end including a head connector for a bone construct. The instrument includes an inner sleeve having a length and configured to receive the driver shank therein and a handle member having a first end and a second end. The inner sleeve and the driver shank have a non-threaded connection. The instrument includes an outer sleeve connected to the second end and concentric with the inner sleeve and a sleeve actuator assembly coupled to the handle member. The sleeve actuator assembly includes a first position where a portion of the length of the inner sleeve extends out from the handle member and a second position where the portion of the length of the inner sleeve that is extended from the handle member is retracted into the handle member.

Various embodiments of tool assemblies are provided having at least one rotary input coupling and at least one linear input coupling for allowing either a rotary output or a linear output (e.g., from a tool driver on a surgical robot) to activate at least one mechanism of the tool assembly. For example, mechanisms of the tool assembly can include a clamping assembly, a firing assembly, an articulation assembly, and a roll assembly. The clamping assembly can open and close jaws of an end effector, the firing assembly can translate a knife assembly through the end effector to fire staples and cut tissue, the articulation assembly can articulate the end effector, and the roll assembly can rotate the elongate shaft and/or the end effector.

Surgical devices and systems having rotating end effector assemblies for treating tissue are provided. Methods for using the same are also provided.

An apparatus and method for an articulating microsurgical instrument is disclosed herein. The articulating microsurgical instrument may be configured to be operable with a Doppler probe, bone grasper, soft tissue grasper/dissector, scissors, flexible forceps, or a suction/irrigation line configured to provide tools within a surgical location that can be adjusted to a desired angle of operation. A tip assembly may comprise an articulating portion at a distal tip and the articulating portion may be configured to deflect upon actuation of an articulation control. The articulation control may be a trigger assembly or a roller wheel. A bayonet-style handle may include a set of posts configured to interact with the one or more control wires during actuation of the articulation control. One or more control wires may be housed in a lumen and actuated using a articulation control of a handle assembly.

A hand-held electromechanical surgical instrument includes a handle housing, a shaft portion extending distally from the handle housing, a firing shaft configured to effect a stapling function of an end effector, and a manual lever coupled to the firing shaft for manually retracting the firing shaft and, in turn, opening the end effector.
