A modular endoscopic device includes a base portion, a driver provided in the base portion, and an endoscope module including an endoscope housing detachably provided in the base portion, an insertion tube including a bendable bending portion and connected to the endoscope housing to be inserted into a body of a subject, and a bending wire configured to transfer a force to bend the bending portion. The endoscope module is detachably attachable to the base portion. The driver is configured to transfer power to the bending wire when the endoscope module is attached to the base portion, and the driver is configured not to transfer power to the bending wire when the endoscope module is detached from the base portion.

Endoscope module and modular endoscopic device including the same

A basket device for an endoscope includes a base tube attached to an end of an endoscope tube and including at least one channel through which an endoscopic camera or a surgical instrument passes, a plurality of baskets provided at locations separate from each other in a radial direction along an edge of an end of the base tube and formed to protrude in a direction in which each of the baskets is to be expanded, and an operator formed to surround the plurality of baskets at the end of the base tube and being slidable in a longitudinal direction of the base tube.

Basket device for endoscope

An arm rest apparatus, according to one embodiment, may comprise: a fixed part fixed to an external object; a horizontal movement module having one end rotatably connected to the fixed part and the other end having two-translational-degree-of-freedom movement with respect to the fixed part; and an arm support module installed to have two rotational degrees of freedom with respect to the other end of the horizontal movement module.

Arm rest apparatus

A positioning arm including a link assembly including a translation link configured to translationally move along a virtual axis passing a remote center of motion (RCM) present at a predetermined position separated from one point and configured to move in at least two directions based on the one point, and a gravity torque compensator configured to provide a compensation torque in a direction opposite to a gravity torque applied to the one point by a self-weight of the link assembly.

Positioning arm

An autonomous endoscopic system capable of controlling movement of an endoscope inserted into a protective sheath installed in the body of a patient includes: an endoscope operating device capable of operating a relative position of the endoscope with respect to the protective sheath, a rolling angle of the endoscope, and a bending angle of a bending portion which is located at the end of the endoscope and is bendable; and a control unit for controlling the endoscope operating device, wherein the control unit controls the endoscope operating device on the basis of a driving record of the endoscope.

Autonomous endoscopic system and control method therefor

A basket actuator includes a base including a base body and a base guide installed in the base body, a slider including a slider body configured to slide along the base guide, and a first slider arm and a second slider arm formed to protrude from the slider body and facing each other, a roller including a roller body rotatably disposed between the first slider arm and the second slider arm and a plurality of roller blades formed to protrude outwardly from the roller body, a wire guide connected to a front end portion of the base body, a wire disposed inside the wire guide and having a first end fixed to the roller, and a basket connected to a second end of the wire. The second slider arm is located rearward in comparison to the first slider arm.

Basket actuator and surgical device including the same

According to an embodiment, an autonomous endoscopic system capable of controlling movement of an endoscope inserted into a protective sheath installed in the body of a patient may comprise: an endoscope operating device capable of operating a relative position of the endoscope with respect to the protective sheath, a rolling angle of the endoscope, and a bending angle of a bending portion which is located at the end of the endoscope and is bendable; and a control unit for controlling the endoscope operating device, wherein the control unit controls the endoscope operating device on the basis of a driving record of the endoscope.

A urolithiasis removing device according to one embodiment can comprise: an insertion tube; a guide which is inserted into the insertion tube and which is relatively movable with respect to the insertion tube; a wire which is inserted into the guide and which is relatively movable with respect to the guide; a basket positioned in front of the wire and capable of holding urolithiasis; and a control unit for determining the size of the urolithiasis on the basis of the relative movement of the guide with respect to the insertion tube or the relative movement of the wire with respect to the guide.
