Abstract: An adjustable marker reference device for identifying surgical instruments includes a base, an upper cover, a set of connecting rods, markers and a fixing button. The base has a first groove, and the upper cover has a second groove. The set of connecting rods is disposed between the base and the upper cover, and has two movable ends and a pivot point. The fixing button extends through the first groove, the pivot point and the second groove. When the fixing button is pressed, the set of connecting rods can freely bring the pivot point to slide along the first groove and the second groove. When the fixing button is not pressed and the pivot point is fixed at one of default positions, the set of connecting rods is fixed. As the set of connecting rods is fixed, virtual lines between any two of the markers meet specific conditions.

Abstract: A sleeve assembly and an endoscope device are provided. The endoscope device includes the sleeve assembly and a lens assembly. The sleeve assembly includes an outer sleeve and an inner sleeve. The outer sleeve has a first opening and a second opening that communicate with each other. The outer sleeve is configured to define a central axis, and the central axis passes through the first opening and the second opening. The inner sleeve is detachably disposed on the outer sleeve. The inner sleeve includes an annular component. The annular component is disposed outside the outer sleeve and surrounds the outer sleeve. The inner sleeve is disposed inside the outer sleeve and closely attached to an inner wall of the outer sleeve. The inner sleeve is configured to be operated to rotate relative to the central axis. The lens assembly is disposed in the inner sleeve.

Abstract: A surgical tool and an identification system for determining usage status of the same are provided. The surgical tool includes a rod surgical instrument, a shielding component and an adapter. The rod surgical instrument includes a rod having two ends being an operation end and a joint end, respectively, a first mark is arranged on the rod, the shielding component is movably sleeved on the rod, and the adapter is detachably combined with the rod surgical instrument. The shielding component located at a first position on the rod shields the first mark as the surgical tool is in an unused state. As the surgical tool is in a used state, and after the rod surgical instrument is separated from the adapter, the shielding component moves from the first position of the rod to a second position of the rod to expose at least part of the first mark.

Abstract: A calibration device includes a calibration member, a handle, a fixing button, and a plurality of first markers. The calibration member includes a calibration body and a calibration groove. The calibration body has a first side and a second side opposite to the first side. The calibration groove is formed on the first side. The handle has a grip portion, and is adjacent to the first side and detachably disposed above the calibration groove. A calibration opening is formed between the handle and the first side. The fixing button is movably arranged in the handle, and has a fixing portion extending toward the calibration groove. The plurality of first markers are disposed on the second side. When the fixing button is pressed, a surgical instrument inserted into the calibration opening is held between the fixing portion and the calibration groove.

Abstract: A transmission device includes a base body and a plurality of driving modules disposed in the base body. Each driving module includes a first transmission set, a linking member, a second transmission set, a third transmission set, a gear set, and a driving motor. The first transmission set includes a slide rail and a slide block. The slide block is fixed on the base body. The linking member is fixed on the slide rail and has a slide shaft. The second transmission set includes a screw rod and a nut, and the nut is fixed on the slide rail. The third transmission set includes a worm rod and a worm gear meshed with the worm rod. The gear set is connected to the worm rod. The driving motor has a driving shaft connected to the gear set.

Abstract: A navigation method for a medical operation and implemented by a robotic system is provided. The method includes the steps of: receiving, at a processor of the robotic system, at least one set of navigation data; receiving or generating at least one three-dimensional model of the virtual object in the navigation data; calculating the navigation data to generate a virtual environment and at least one navigation instruction; and presenting, at a user interface associated with the robotic system, the virtual environment and/or the navigation instruction to a user of the robotic system for the user to refer to during the medical operation.

Abstract: A surgery assistive system includes an instrument having a tool and a manipulator connected to the tool, a spatial sensor system for detecting spatial information of the tool, and a computer system for manipulating a kinematic state of the manipulator. A method for obtaining surface information by the surgery assistive system includes the steps of: defining a target region and a plurality of reference points on a virtual anatomical model of a subject; prompting a user to generate sampling information by using the instrument to sample a plurality of sampling points on the subject corresponding to the reference points; and designating the sampling information as surface information of the sampling points. Each piece of the sampling information includes a coordinate of one of the sampling points, an angle of a contact of the tool at the sampling point, and parameters associated with the contact.

Abstract: A calibration device for a computer-assisted surgical instrument includes a rigid body, stabilization members, and references structurally or mechanically complementary to the stabilization members and disposed on opposite sides of a manipulator of the instrument. Kinematic state of the manipulator is defaulted when the calibration device is connected to the instrument by the stabilization members passing through the rigid body and removably attaching to the references. A calibration method for a computer-assisted surgical instrument implemented by a computer system includes the steps of: prompting a user to connect the calibration device to the instrument; determining if the calibration device is properly connected to the instrument; and generating default kinematic information of the manipulator of the instrument if the calibration device is properly connected to the instrument. The calibration device and method effectively improve accuracy and precision of computer-assisted surgeries.
