  • Publication number: 20220361975
    Abstract: A medical instrument comprises an instrument control surface configured to mate with an instrument sterile adapter to receive input drive forces through the sterile adapter to control actuation of the surgical instrument, the instrument control surface comprising a first opening defined in the instrument control surface. A latch structure of the instrument comprises a locking surface configured to engage a latch arm in response to the latch arm being received in the opening, wherein in an engaged state of the latch arm with the locking surface the medical instrument is attached to the instrument sterile adapter and the latch structure prevents movement of the latch arm in a first direction. A latch release is moveable in the engaged state of the latch arm with the locking surface to exert a force causing movement of the latch arm in a second direction to disengage the latch arm from the locking surface.

  • Patent number: 11446105
    Abstract: An instrument sterile drape includes a plastic sheet and an instrument sterile adapter (ISA) coupled to the plastic sheet. The ISA includes bottom and top plates located on opposite sides of the plastic sheet plate and joined together. A passage in the bottom plate allows an instrument carriage flux connection to pass through the plastic sheet and the bottom plate to be adjacent to the top plate. The top plate includes a signal transmission area that will be adjacent to an upper surface of the flux connection of the instrument carriage. A flux connector may close an opening in the signal transmission area of the top plate and provide a path for an electrical or optical signal. The signal transmission area of the top plate may be thinned to allow an RFID sensor to be closer to an RFID device in a surgical instrument attached to the instrument sterile adapter.

  • Patent number: 11389259
    Abstract: A surgical instrument includes a proximal control mechanism having an instrument control surface. The instrument control surface has two openings through which two resilient latch arms can be inserted to engage a fixed latch structure contained within the proximal control mechanism. The fixed latch structure provides two lead-in ramps that force the resilient latch arms onto locking surfaces. The resilient latch arms are contained entirely within the proximal control mechanism when engaged. Inward forces can be applied to two buttons to apply an outward force on the resilient latch arms and release them from the locking surfaces of the fixed latch structure. Each of the two buttons is accessible from one of two opposite outside surfaces of the proximal control mechanism.

  • Patent number: 11357592
    Abstract: Minimally invasive robotic surgical instruments and related methods are disclosed. A surgical instrument includes an interface fitting that couples a proximal chassis of the instrument with a holding fixture of a robotic manipulator. A securing feature releasably prevents relative axial sliding between the interface fitting and the chassis. In response to binding of the surgical instrument within a minimally invasive surgical site so as to inhibit removal of the surgical instrument from the surgical site and inhibit disengagement of the interface fitting from the holding fixture, the securing feature can be released to allow relative axial sliding between the interface fitting and the chassis, thereby allowing the holding fixture and the interface fitting to be separated from the rest of the surgical instrument and repositioning of the robotic manipulator out of the way.

  • Publication number: 20220039893
    Abstract: A device to regulate tension of an actuation element for actuating movement of a surgical instrument includes an elastically deformable body configured to be coupled to the actuation element. The deformable body is configured to elastically deform in response to a state of slack occurring in the actuation element. As slack occurs in the actuation element, the deformable body is configured to divert a path of the actuation element to accommodate the slack so the path of the actuation element differs from an axis the actuation element follows prior to the actuation element developing slack. A force transmission mechanism for a teleoperated surgical instrument includes a chassis, an actuation input mechanism, an actuation element, and a tension regulator coupled to the actuation element to compensate for slack of the actuation element.

  • Patent number: 11098803
    Abstract: Sealing assemblies and methods are disclosed for sealing a surgical instrument having an internal drive shaft subject to lateral displacement. A sealing assembly includes a rigid portion shaped to interface with an instrument shaft of the surgical instrument. A laterally oriented slot is open at a radially perimeter location and configured to receive an o-ring seal via the perimeter location. Apertures are disposed on opposing sides of the slot and open to the slot. The apertures are configured to receive the drive shaft there through and are larger than the drive shaft to accommodate lateral displacement of the drive shaft. The slot includes opposing internal sides spaced to interface with opposed axial surfaces of the o-ring seal. The seal inhibits axial transmission of an insufflated gas and/or bodily fluids while accommodating lateral displacement of the drive shaft.

  • Patent number: 11045274
    Abstract: An instrument carriage provides control of a surgical instrument coupled to the instrument carriage. The instrument carriage includes a control surface that is coupled to the surgical instrument to provide the control. A detection pin having a first distal end that extends from the control surface is coupled to the instrument carriage. A sensor fixed relative to the instrument carriage detects a position of the detection pin. A carriage controller coupled to the sensor, provides a signal that indicates at least a first state and a second state responsive to a distance between the distal end of the detection pin and the control surface. The signal may indicate if an instrument sterile adapter is coupled to the control surface of the instrument carriage. A third state of the signal may indicate if a surgical instrument is coupled to the instrument sterile adapter.
