The embodiments disclosed herein relate to various robotic and/or in vivo medical devices having compact joint configurations and at least three degrees of freedom. Other embodiments relate to various medical device components, including forearms having grasper or cautery end effectors, that can be incorporated into certain robotic and/or in vivo medical devices.

A robotic surgical system includes a surgical instrument and a robotic surgical assembly. The robotic surgical assembly defines an instrument opening and includes a floating plate and a drive assembly. The floating plate is movable between an extended position and a compressed position. The surgical instrument is laterally receivable in the instrument opening of the robotic surgical assembly while the floating plate is disposed in the compressed position. The floating plate is movable to the extended position to couple the surgical instrument to the robotic surgical assembly while the surgical instrument is received in the instrument opening of the robotic surgical assembly.

A robotic surgical system includes a robotic arm, a carriage coupled to the robotic arm, a drive belt, and a motor supported by the carriage. The carriage rotatably supports an instrument rotation pulley and a motor axis pulley. The drive belt is coupled to the instrument rotation pulley and the motor axis pulley. The motor includes a coupling that is driven by the motor upon an actuation of the motor. The coupling is engaged with the motor axis pulley such that rotation of the motor axis pulley rotates the drive belt to rotate the instrument rotation pulley.

A surgical instrument for coupling to a robotic surgical assembly configured to transfer rotational forces to the surgical instrument is provided. The surgical instrument includes an elongated shaft, an end effector coupled to a distal end of the elongated shaft, and a drive assembly operatively coupled to the end effector. The drive assembly includes one or more cables connected to the end effector. Movement of the one or more cables actuates a movement of the end effector. The one or more cables may be coated with parylene.

A sterile interface module includes a body member that couples a surgical instrument to a robotic surgical assembly, a first drive transfer assembly supported by the body member, and a rotatable collar supported on the body member. The first drive transfer assembly includes a drive coupler and a transfer shaft extending from the drive coupler. The drive coupler is engagable with the robotic surgical assembly and the transfer shaft is engagable with the surgical instrument. The drive coupler and the transfer assembly are robotically movable to operate an end effector of the surgical instrument. The rotatable collar is operably associated with the first drive transfer assembly and is manually movable relative to the body member to manually operate the end effector of the surgical instrument.

A robot arm according to the present invention includes: a shoulder joint assembly which is connected to an upper arm portion, and includes a drive unit for generating driving power; an elbow joint assembly which is provided between the upper arm portion and a forearm portion, and operates by being supplied with driving power from the drive unit; and a wrist joint assembly which is provided between the forearm portion and a hand portion, and operates by being supplied with driving power from the drive unit.

A robot including a base having a flat mounting surface section to be set on an installation surface by a fixing part, and also including a movable unit that is movable relative to the base. The base includes a tip-over prevention member that is disposed in a switchable manner between a state where the tip-over prevention member at least protrudes forward from the mounting surface section in a moving direction when a relocating process is performed and a state where the tip-over prevention member does not protrude forward from the mounting surface section.

The embodiments disclosed herein relate to various robotic and/or in vivo medical devices having compact joint configurations and at least three degrees of freedom. Other embodiments relate to various medical device components, including forearms having grasper or cautery end effectors, that can be incorporated into certain robotic and/or in vivo medical devices.

A transmission device is provided, including a first housing, a second housing connected to the first housing, a third housing axially connected to the second housing, an adapter disposed on the third housing, a first power shaft actuating the first housing and the second housing to rotate, a second power shaft actuating the third housing to rotate, and a third power shaft actuating the adapter to rotate. The second and third power shafts are a coaxial structure. The first power shaft is an independent rod. Therefore, a motor loaded with a smaller rotation inertia and being thus cheaper can be used to drive the first power shaft, and the transmission device can have a reduced cost.

A system for conveying an industrial robot includes: a control module, at least one automatic guided vehicle, and at least one electromagnetic base. An industrial robot is installed each electromagnetic base, which may attract a metallic plate fixed to the ground, thereby fixing the industrial robot installed on the electromagnetic base. An electromagnetic base is configured to, according to a first control instruction sent by the control module, stop attracting the metallic plate so that the industrial robot is movable. An automatic guided vehicle is configured to, according to a second control instruction sent by the control module, convey, to a target position, the industrial robot installed on the electromagnetic base that has stopped attracting the metallic plate. Finally, an electromagnetic base is further configured to, according to a third control instruction sent by the control module, attract the metallic plate fixed to the ground in the target position.
