Robotic surgical instruments with a fluid flow control system for irrigation, aspiration, and blowing

Abstract: In one embodiment of the invention, a robotic surgical instrument is provided for the control of flows of one or more fluids into and out of a surgical site. The robotic surgical instrument may include a housing, a flow control system, a hollow tube, and one or more hose fittings. The housing to couple the instrument to a robotic arm. The flow control system mounted in the housing includes one or more controlled valves to control the flow of one or more fluids. The hollow tube has a first end mounted in the housing coupled to the flow control system. A second end of the hollow tube has one or more openings to allow the flow of fluids into and out of the surgical site. The hose fittings have a first end coupled to the flow control system and a second end to couple to hoses.

Surgical Instrument with Shiftable Transmission

Abstract: A surgical tool having an elongated shaft having a proximal end and distal end. A surgical end effector is located about the distal end. The surgical end effector has a plurality of effector mechanisms comprising a plurality of degree of freedoms. An effector body is located at the proximal end. The effector body includes a plurality of motor interfaces for driving the plurality of effector mechanisms. A transmission is coupled to the effector body

Surgical instrument motor pack latch

Abstract: A latch mechanism selectively retains a first assembly to a second assembly. The first and second assemblies are configured for sliding engagement along an engagement axis. The latch mechanism includes a latch shaft mounted to the first assembly to rotate about a latch shaft axis, a torsion spring to bias the latch shaft relative to the first assembly, and a transverse latch member coupled with the second assembly. The latch mechanism is configured to automatically latch in response to the first assembly being pushed toward the second assembly. The transverse latch member interacts with the latch shaft to rotate the latch shaft in a first direction in response to movement of the first assembly toward the second assembly. Further motion of the first assembly toward the second assembly results in rotation of the latch shaft opposite to the first direction into a retention configuration that retains the transverse latch member.

Interface apparatus with cable-driven force feedback and four grounded actuators

Abstract: A system for providing realistic sensation within a simulation system by providing tactile (haptic) feedback to a user. The system includes an engageable practice tool that the user engages and a mechanical simulation apparatus coupled to the practice tool. The mechanical simulation apparatus includes a ground member (46), a mechanical linkage (38) rotatably coupled to the ground member (47), a linear axis member coupled to the practice tool and the mechanical linkage (38), at least four actuators (62, 64, 66, 70) coupled to the ground member, sensors (65, 67, 69) for sensing movement of the actuators, and at least three cables in contact with the at least four (actuators ) (65, 64, 66, 70) and coupled to the mechanical linkage (38). An interface device is coupled to the simulation apparatus and a host computer (20) is coupled to the interface device (14) for implementing an application program. The application program provides signals for the actuators (62, 64, 66, 70) to move the cables (130) and thereby move the mechanical linkage (38).

Robotic Surgical Systems With Fluid Flow Control For Irrigation, Aspiration, and Blowing

Abstract: In one embodiment of the invention, a robotic surgical system is provided including a master control console and a surgical manipulator The master control console generates control signals to cause one or more fluids to flow into or out of a surgical site The surgical manipulator is coupled to the console to receive the control signals and includes at least one robotic arm and a surgical instrument coupled thereto The surgical manipulator controls the surgical instrument in response to the control signals to control the flow of the one or more fluids into or out of the surgical site The surgical instrument has a first robotically controlled valve that is responsive to the surgical manipulator and a hollow tube having a first end coupled to the first robotically controlled valve with an opening at a second end to direct the flow of one or more fluids

Surgical Stapling Apparatus

Abstract: A surgical stapling device particularly suited for endoscopic procedures is described The device includes a handle assembly and an elongated body extending distally from the handle assembly The distal end of the elongated body is adapted to engage a disposable loading unit A control rod having a proximal end operatively connected to the handle assembly includes a distal end extending through the elongated body A control rod locking member is provided to prevent movement of the control rod until the disposable loading unit is fully secured to the elongated body of the stapling device

Abstract: Newness and distinctiveness is claimed in the features of ornamentation as shown inside the broken line circle in the accompanying representation.

Surgical stapling instrument with an articulatable end effector

Abstract: A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

Articulating surgical stapling instrument incorporating a two-piece e-beam firing mechanism

Abstract: A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

Surgical instrument having recording capabilities

Abstract: A surgical instrument. The surgical instrument has an end effector and a trigger in communication with the end effector. The surgical instrument also has a first sensor and an externally accessible memory device in communication with the first sensor. The first sensor has an output that represents a first condition of either the trigger or the end effector. The memory device is configured to record the output of the first sensor. In various embodiments, memory device may include an output port and/or a removable storage medium.
