A medical device having a mechanism adapted to convert a single translational input into multiple rotational outputs. An embodiment includes a hinge pin assembly in operable communication with a single input actuator. The hinge pin assembly includes a housing configured to translate in response to actuation of the input actuator. The housing translates about the length of a hinge pin. The housing has a plurality of concentrically aligned annular rings. An upper pinion and a lower pinion are in operable communication with the housing such that linear translation of the housing cause the pinions to rotate. Each pinion is in operable communication with linear gear racks, axles, or other force transferring components. The force transferring components are in operable communication with a pivotable distal end of the medical device. As a result, the linear input causes each distal end of the medical device to pivot with respect to its respective shank.

A surgical instrument system comprising a handle, a shaft, and a disposable power module is disclosed. The handle comprises a motor, a control switch, and a motor-control processor which is in communication with the control switch. In various instances, the disposable power module comprises a disposable battery and a display unit configured to indicate at least one function of the surgical instrument system.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

A surgical robotic system has a robotic grasper, a user interface device (UID), and one or more processors communicatively coupled to the UID and the robotic grasper. The system detects a directive to engage or re-engage a teleoperation mode, determines that the system is in a non-teleoperation mode, receives a sequence of user actions through the UID, determines the UID matches a jaw angle or a grip force of the robotic grasper, and transitions into teleoperation mode. Other embodiments are also described and claimed.

An electrocautery unit for connecting to a handle of an electrocautery device, the unit comprises a body, a light unit and an electrode. The body has a body proximal end and a body distal end, and a body axis extending lengthwise along the center of the body. The body's proximal end comprises a connecting element for connecting said body to a handle having a handle axis extending lengthwise along the center of the handle, so that said body axis is coaxial with said handle axis when said body is connected to said handle. The light unit may be constructed and arranged to emit a light having a central axis coaxial with said body axis. The electrode comprises a proximate end connected to the body distal end, and an electrode tip at a distal said. When the electrode is connected to the body, the electrode lays outside of the body axis and extends into said body axis such that the electrode tip is within said body axis, wherein said light and said electrode tip are coaxial to said body axis and said handle axis.

A surgical device comprising: (1) a handpiece having a distal end portion; (2) a tubular member extending from the distal end portion, the tubular member having a lumen therethrough, the lumen comprising: (a) a proximal lumen portion, (b) a distal lumen portion, (c) a first central lumen portion, and (d) a second central lumen portion, the second central portion being located between the proximal lumen portion and the first central lumen portion, wherein the distal lumen portion diverges as the distal lumen portion extends away from the first central lumen portion in a distal direction, and the second central lumen portion diverges as the second central lumen portion extends away from the first central lumen portion in a proximal direction and: wherein the tubular member has wall with a substantially uniform thickness about the first central lumen portion.

A jaw member of a surgical instrument includes a structural body including a tissue-facing surface having an elongated opening defined therethrough and defining an internal cavity in communication with the elongated opening. A jaw liner of a material that is not conducive to molding includes an internal portion substantially filling the internal cavity and extending to the elongated opening. A method of manufacturing a jaw member of a surgical instrument includes preparing a material, forging the material into an internal cavity defined within a structural body of a jaw member, and setting the material such that the material substantially fills the internal cavity and is retained therein thereby forming a jaw liner of the jaw member.

A surgical instrument includes a first lever element and a second lever element interconnected by a lever element hinge. Each lever element includes a grip portion and a jaw portion. A first spring portion and a second spring portion are proximally connected to the grip portions. A proximal free end of the first spring portion is coupled to a proximal free end of the second spring portion by a hinged joint. The hinged joint includes a hinge pin and at least one bearing eye. The at least one bearing eye forms a continuous longitudinal slit for radial insertion of the hinge pin. The slit extends diagonally relative to the axis of the at least one bearing eye so that at least one spring portion has to be twisted during radial insertion of the hinge pin into the at least one bearing eye.
