Abstract: Apparatus for measuring size of a cup for hip arthroplasty according to the present disclosure includes a scale plate marked with a scale to measure size, a first leg portion fixed to one end of the scale plate, and a second leg portion slidably moved relatively to the first leg portion along the scale plate, in which the second leg portion is marked with reading line. First and second jaws for contacting the cup are provided with 180° rotational symmetry on ends of the first and second leg portions, respectively. Central portions of the first and second jaws are bent to protrude in direction in which the first and second leg portions are farther away from each other, so that when contacting inner diameter of the cup, the jaws form one-point contact with the cup, and when contacting outer diameter of the cup, form two-point contact with the cup.

Abstract: The present disclosure provides a clamp for attaching or detaching a medical shaver, in which the clamp is provided for attaching and detaching a suction tube (30) detachably coupled to and rotated together with a shaft (20) rotated in a shaver body, and includes: a body; a detachment groove (120) formed in a direction perpendicular to a longitudinal direction on a front surface of the body; a detachment slit (125) formed in a direction perpendicular to the longitudinal direction on an upper surface of the body to communicate with the detachment groove; and an attachment groove (145) formed along the longitudinal direction at a center of a right side surface of the body.

Abstract: A power tool for orthopedic surgery is provided, which can be coupled with an attachment having one or more first magnets mounted thereon, and include a power tool body including a power tool case, an attachment fastening portion connected to one end of the power tool body, a motor power transmitting portion protruding toward the attachment fastening portion and transmitting power to the attachment, a motor that drives the motor power transmitting portion, a first magnetic sensor portion including a first magnetic sensor capable of sensing a magnetic field strength or number of the one or more first magnets, a control portion that controls the motor to operate below a preset maximum rotational speed and maximum torque value according to the magnetic field strength or the number sensed by the first magnetic sensor, and a power supply that supplies power to the motor and the control portion.

Abstract: The present disclosure relates to an electrode suction drill system including a manipulator and a hollow catheter tube, and including: a first electrode and a second electrode provided apart from each other on a front end of the catheter tube; a steering ring provided at an inner front end of the catheter tube; first and second wires positioned inside the catheter tube and having one ends connected to the steering ring; a drill wire provided in an inner hollow portion of the catheter tube; a thread formed on an outer circumferential surface of the drill wire; and a motor provided inside the manipulator and fastened to one end of the drill wire to rotate the drill wire, in which a tip of the catheter tube performs a steering operation by a manipulation of the first and second wires, and as the drill wire is rotated by the rotation of the motor, lesion site tissue in a body is suctioned into the catheter tube by the thread.
