A surgical instrument assembly comprises a guide tube and first and second instruments extended within the guide tube. The first instrument comprises a first elongated shaft coupled to a first end effector. The second instrument comprises a second elongated shaft coupled to a second end effector. The surgical instrument assembly may also comprise an imaging assembly extended distally of the guide tube. The imaging assembly comprises a distal imaging component and an elongated imaging shaft. The distal imaging component is coupled to a distal end of the elongated imaging shaft by a pivot joint. The imaging assembly has a first configuration with the elongated imaging shaft aligned with the distal imaging component when inserted through the guide tube and a second configuration with the distal imaging component pivoted out of alignment with the elongated imaging shaft when the distal imaging component is extended from the guide tube.

In one embodiment of the invention, a robotic surgical system includes a combined laser imaging robotic surgical tool, a control console, and a laser generator/controller. The tool is mounted to a first robotic arm of a patient side cart. The tool has a wristed joint and an end effector coupled together. The end effector has a laser-emitting device to direct a laser beam onto tissue in a surgical site and an image-capturing device to capture images of the tissue in the surgical site. The control console, in communication with the tool, receives the captured images of tissue in the surgical site and displays the captured images on a display device to a user. The laser generator/controller is coupled to the tool and the control console to control the emission of the laser beam onto tissue of the surgical site.

Surgical system with combined laser ablation/ imaging tool

Certain aspects relate to systems and techniques for medical robotic systems that leverage a versatile, open kinematic chain together with a set of medical-procedure-specific software-controlled actuation constraints in order to perform a variety of medical procedures. The robotic system can be operated in a first mode by identifying a remote center and constraining the actuation of motorized joints to maintain intersection of at least an insertion axis with the remote center. The robotic system can be operated in a second mode by identifying a virtual rail position and constraining the actuation of motorized joints to maintain alignment of the insertion axis along the virtual rail.

Medical robotics systems implementing axis constraints during actuation of one or more motorized joints

An instrument device manipulator (IDM) is attached to a surgical arm of a robotic system and comprises a surgical tool holder and an outer housing. The surgical tool holder includes an attachment interface that can secure a surgical tool in a front-mount configuration (where the attachment interface is on a face opposite of a proximal extension of the surgical tool) or a back-mount configuration (where the attachment interface is on the same face as the proximal extension of the surgical tool). The surgical tool holder may rotate continuously within the outer housing. In a back-mount configuration, the surgical tool holder may have a passage that receives the proximal extension of the tool and allows free rotation of the proximal extension about the rotational axis. A surgical drape separates the IDM and robotic arm from a tool, while allowing electrical and/or optical signals to pass therebetween.

Instrument device manipulator with roll mechanism

A surgical instrument is described that includes a surgical effector moving with N degrees of freedom for manipulation of objects at a surgical site during surgical procedures. The N degrees of freedom are manipulated by N+1 input controllers and a plurality of cables, the controllers and cables coupled to the surgical effector and configured to change the orientation of the surgical effector about the N degrees of freedom when actuated. In some embodiments, the N+1 input controllers and plurality of cables are further coupled to a pantograph, the pantograph configured to move in a reciprocal manner to the surgical effector when the input controllers and cables are actuated.

Length conservative surgical instrument

A wrist joint, such as for a surgical instrument, may include a first disc, a second disc adjacent the first disc, a drive tendon connecting the first disc and the second disc. The first disc and the second disc may include respective opposing gear features that intermesh with one another. The first disc and the second disc may further include opposing load bearing surfaces. In response to tensioning the drive tendon, the first and second discs rotate relative to each other. The first and second discs may have a maximum rotational range of motion greater than about +/&#x2212;45 degrees relative to each other.

For kinetic sizing, the dynamic torque to be provided by a robotic system may be based off of, in part, a maximum acceleration. Rather than trying to extract maximum acceleration from many samples, a relationship of velocity to acceleration from repetitive user inputs relative to a non-surgical target in different situations (e.g., accurate, fast, or balance tracing of the target movement) is established. The velocity for any given situation may be used to estimate the acceleration from the relationship. Rather than using many trajectory samples from many users, a synthetic trajectory may be used. The synthetic trajectory may be fit to user data while maintaining high-coverage properties for direction of movement for any given pose of the robot. Alternatively, a virtual trajectory decoupled from time is used. The virtual trajectory samples the directions at any given pose in a global high-coverage manner, without specifically using a time-dependent sequence of poses.

Trajectory representation in design and testing of a surgical robot

A surgical apparatus comprises an instrument shaft having a proximal end and a distal end, an end effector coupled to the distal end of the shaft, and a sheath disposed on an external surface of the instrument shaft. The sheath has a first section made of ePTFE and a second section made of a second material, wherein the second section provides a friction seal with the shaft, and wherein the ePTFE is gas-permeable.

Sheath for surgical instrument

A surgical instrument is inserted through a guide tube. The surgical instrument exits at an intermediate position of the guide tube and is oriented to be substantially parallel to the guide tube's longitudinal axis as it exits. A stereoscopic image capture component is on the guide tube between the intermediate position and the guide tube's distal end. The image capture component's field of view is generally perpendicular to the guide tube's longitudinal axis. The guide tube is jointed to allow the image capture component to be moved. The surgical instruments and the guide tube are telemanipulatively controlled.

Side looking minimally invasive surgery instrument assembly

A surgical instrument may comprise a shaft; a wrist structure coupled to the shaft; an end effector coupled to the wrist structure; and an actuation element extending through the shaft and the wrist and coupled to the end effector. The wrist structure may be articulatable in multiple degrees of freedom relative to the shaft, and the actuation element may follow a twisted path along at least a portion of a length of the wrist structure, the twisted path having an angular extent of less than 360 degrees over the length of the wrist.
