Techniques for automated rotation of a needle in a computer-assisted system include an end effector having a drive mechanism configured to be coupled to a curved needle and configured to rotationally actuate the curved needle along an arcuate path and a control unit coupled to the drive mechanism. The control unit is configured to, in response to receiving a first input, cause the drive mechanism to rotationally actuate the curved needle by a first preset rotation amount along the arcuate path, and, in response to receiving a second input, cause the drive mechanism to rotationally actuate the curved needle by a second preset rotation amount along the arcuate path.

Systems and methods for providing assistance to a surgeon during an implant surgery are disclosed. A method includes defining areas of interest in diagnostic data of a patient and defining a screw bone type based on the surgeon's input. Post defining the areas of interest, salient points are determined for the areas of interest. Successively, an XZ angle, an XY angle, and a position entry point for a screw are determined based on the salient points of the areas of interest. Successively, a maximum screw diameter and a length of the screw are determined based on the salient points. Thereafter, the screw is identified and suggested to the surgeon for usage during the implant surgery.

A surgical system according to one or more embodiments may include: manipulators respectively supporting an endoscope and first and second surgical instruments; a remote control apparatus including a display device, a first operation handle for right hand to operate the first surgical instrument, and a second operation handle for left hand to operate the second surgical instrument; and a control apparatus. The control apparatus may display, on the display device, a graphical user interface, overlapped with the image captured by the endoscope, the graphical user interface including a first area that displays information on the first surgical instrument to be operated by the first operation handle, a second area that displays information on the second surgical instrument to be operated by the second operation handle, and a third area that displays information on the endoscope, which are arranged side by side in order from right to left.

A method for creating a patient-specific surgical plan includes receiving one or more pre-operative images of a patient having one or more infirmities affecting one or more anatomical joints. three-dimensional anatomical model of the one or more anatomical joints is created based on the one or more pre-operative images. One or more transfer functions and the three-dimensional anatomical model are used to identify a patient-specific implantation geometry that corrects the one or more infirmities. The transfer functions model performance of the one or more anatomical joints as a function of anatomical geometry and anatomical implantation features. surgical plan comprising the patient-specific implantation geometry may then be displayed.

An ophthalmic system for examining a subject eye of an examinee includes a plurality of examination units, a robot mechanism, and a controller. The plurality of examination units have housings different from each other, perform examinations different from each other, and include at least a first examination unit and a second examination unit. The robot mechanism has a holding unit that holds and releases either the first examination unit or the second examination unit, and a moving unit that is connected to the holding unit and moves three-dimensionally. A controller controls driving of the robot mechanism to adjust a relative positional relationship between the subject eye and the first examination unit or the second examination unit held by the holding unit. The first examination unit or the second examination unit is replaced to be held by the holding unit for performing a different examination on the subject eye.

A pulley and a structure having the pulley connected with a driven unit are provided. The pulley includes a wheel portion and a lug portion. The wheel portion includes two circular end surfaces opposing each other and a side surface connecting the two end surfaces. The side surface includes a main arc face and a branch arc face. The branch arc face has a head end connected to the main arc face and a tail end configured to connect a strap. The branch arc face has a width in an axial direction of the wheel portion smaller than a width of the main arc face. The lug portion is fixed to the wheel portion, disposed at a position adjacent to the branch arc face along the width of the main arc face and extends to protrude beyond the branch arc face in a radial direction of the wheel portion.

The present invention relates to MIS robotic control terminal and robot system, wherein the system comprises: a master manipulator handle, for driving at least one slave manipulator coupled thereto; a display-and-control portion, for controlling the master manipulator handle and the at least one slave manipulator coupled to the master manipulator handle; and a foot-operated clutch portion, for breaking signal communication between the master and slave manipulators; in which when a human operator uses the display-and-control portion to establish signal communication between the master manipulator handle and any said slave manipulator, the display-and-control portion is at least capable of according to types of instruments on two said slave manipulators that are currently in communicative connection to master manipulator handles that are different from each other, respectively, defining a moving space of any said slave manipulator in a corresponding surgical area by means of calling movement schemes corresponding to the types of the instruments. The present invention is highly integrated, compact, easy to be understood, and highly human-machine interactive, making the surgical process safe and efficient; and the operator can move freely and flexibly, which can relieve the operator from fatigue.
