The present invention provides a two-part robotic device for positioning of a hand tool, comprising: a. a fixed base unit constantly fix to its position; b. a detachable body unit reversibly coupled to said fixed base unit, coupled to said current medical instrument;
wherein said fixed base unit is adapted to provide independent movement to said hand tool, said independent movement selected from the group consisting of rotation and translation, and further wherein said detachable body unit is removable and replaceable from said fixed base unit such that upon exchange of said hand tool for a second hand tool, said second hand tool is placed in substantially the same location as the location of said hand tool prior to said exchange.

A suspension arm assembly including at least three horizontally aligned members relatively rotatable about each other. Each adjacent pair of members are connected to each other by a joint. At least one conduit extends along the at least three horizontally aligned members, with the at least one conduit being routed horizontally along the horizontally aligned members and not being located within a periphery of the at least three horizontally aligned members.

Knuckle joint assembly for a medical device support system. The knuckle joint assembly includes a cartridge assembly that includes a cartridge housing and a rotary bearing. The cartridge housing includes a bore having a central axis and a bearing mount in the bore. The rotary bearing is press fitted in the bearing mount and configured to receive axially therethrough a spindle to rotatably support the spindle about the central axis. The knuckle joint assembly includes a retaining clip and a retaining pin. The retaining clip is selectively movable to disengage and engage a groove in a spindle to respectively support or release the spindle along a central axis. The retaining pin is movable between a first position to allow movement of the retaining clip between positions but prevent removal of the retaining clip, and a second position to block movement of the retaining clip from the engaged position.

A minimally invasive surgical device characterized by comprising: a manipulable handle (2) manipulated by a user inside a body cavity, a treatment part (3) that holds a specific swappable surgical instrument that is inserted into the body cavity and manipulated using the manipulable part, and a linking part (4), provided between the manipulable handle and the treatment part, for disposing the surgical instrument held by the treatment part in a desired orientation at a desired position within the body cavity. The linking part comprising: two or more connecting parts (7a, 7b, 8a, 8b) that are connected in series in the longitudinal direction of the linking part, and form a joint (7, 8) that enables rotation around the longitudinal axis or an axis orthogonal to the longitudinal axis; and a linking part control mechanism that moves the two or more connecting parts toward or away from each other to open or constrict the angle of the joint around the longitudinal axis and/or the angle thereof around an axis orthogonal to the longitudinal axis, thereby disposing the treatment part at the desired position and in the desired orientation within the body cavity.

Provided is a control device that electrically controls a medical observation apparatus configured to capture an image of an observation target and includes a voice recognition section, a recognized-information processing section, a switch input reception section, and a control section. The voice recognition section recognizes a voice inputted from outside. Based on a result of recognition by the voice recognition section, the recognized-information processing section determines processing to be executed by the medical observation apparatus. The switch input reception section receives an input of an operation signal based on an operation performed on a switch. Upon detecting a first operation signal received by the switch input reception section or upon acquiring information regarding processing determined by the recognized-information processing section, the control section causes the voice recognition section to start voice recognition processing and causes the medical observation apparatus to execute the processing determined by the recognized-information processing section.

A mounting adapter has a proximal end for interfacing with a surgical stabilizer arm and a distal end for interfacing with a tissue manipulator tool. The adapter includes a receiver body defining a bore having an opening at the distal end for receiving the shaft of a manipulator tool. The receiver body has a detent projecting radially into the bore. A ball stem projects at the proximal end and is configured for insertion into a collet of the stabilizer arm. The detent is radially displaceable between 1) a radially outward position when the adapter is in an unlocked state in which the shaft of the manipulator tool is slidable into or out of the bore and 2) a radially inward position when the adapter is in a locked state in which the detent captures the shaft of the manipulator tool.

A computer-assisted device includes a first repositionable arm configured to support a first end effector, a second repositionable arm configured to support a second end effector, and a control unit. The control unit configured to monitor an actual motion of at least one structure selected from the group consisting of the first repositionable arm and the first end effector, determine a deviation threshold based on at least one parameter selected from the group consisting of a mode of operation of the first end effector and a mode of operation of the computer-assisted device, and in response to determining that the actual motion of the at least one structure deviates from a desired motion of the at least one structure by more than the deviation threshold, halt motion of the first repositionable arm and the first end effector or halt motion of the second repositionable arm and the second end effector.

A surgical robotic arm (520) for use with an external vision system (512) includes onboard control and at least four degrees of articulation. The robotic arm (520) can position various tools (534) in the surgical theatre responsive to positional feedback from the vision system (512). Exemplary tools (534) include a handpiece (519) that includes a motorized burr or saw, a cutting guide (542) for a handheld saw, and a laser to actively define a resection area for a surgeon. The tool (534) or a reference point on the arm (520) relative to the tool (534) includes fiducial marks to register the position of the tool (534) with the vision system (512). Exemplary tools (534) are especially suited for knee and hip arthroplasty and can be moved under processor or manual control.

Systems, assemblies, devices, and methods for positioning surgical devices at surgical sites are disclosed. An adjustment assembly may include a first connector configured to connect to a surgical articulating arm and a second connector configured to connect to a tool, such as a surgical access tube. A joint assembly may be coupled to the first connector and an elongated assembly may be coupled to the joint assembly and the second connector. An actuator may be coupled to the joint assembly and may be adjusted to secure the elongated assembly in a desired position. One or more clips may be utilized with a surgical access tube to secure a surgical tool within a surgical access tube. The clip may have a single port or more than one port.

A medical device support system including a shaft, an extension arm, and a hub mounted to the shaft for pivotable movement of the extension arm about a rotation axis of the shaft. The hub includes a cavity including first and second contact faces, and at least one floating stop movably disposed in the cavity. The hub is pivotably mounted for a range of at least 360-degrees rotation about the rotation axis. The at least 360-degrees rotation range is based on a compound of a first rotation range and a second rotation range. The first rotation range is defined by a first movable amount of the at least one floating stop between first and second stop surfaces fixed relative to the shaft. The second rotation range is defined by a second movable amount of the at least one floating stop between the first and second contact faces of the hub.
