The present disclosure relates to an apparatus for closed reduction of a bone fracture. The apparatus includes at least: a pulling adaptor including: a handle configured to be gripped by an operator; an insertion rod that is extended from the handle in a longitudinal direction of the handle, and configured to be inserted into the bone fracture which is depressed in at least one area thereof; and a pulling lug that is bent and extended from an end of the insertion rod such that a longitudinal direction of the pulling lug is perpendicular to a longitudinal direction of the insertion rod or such that the pulling lug is inclined with respect to the insertion rod, the pulling lug being configured to be inserted into the at least one depressed area of the bone fracture, in order to pull the bone fracture.

Apparatus for closed reduction of bone fracture

The present disclosure relates to a tool for a closed reduction of a fracture. The tool includes at least: a winding portion having a winding shape; a support extending from the winding portion in a normal direction relative to a plane of the winding shape; and a handle extending from the support in the normal direction, and configured to be gripped.

Tool for closed reduction of fracture

A catheter and a surgical medical device. The catheter includes at least; a first elastic member positioned at an end portion of the catheter: a second elastic member connected with the first elastic member, the second elastic member being curved with a first radius of curvature to protrude toward a first direction; a first wire connected with a first surface of the first elastic member, and configured to pull the catheter to bend the catheter in the first direction; a second wire connected with a second surface of the first elastic member, which is opposite to the first surface, and configured to pull the catheter to bend the catheter in a second direction; and a tube containing the first elastic member, the second elastic member, the first wire, and the second wire.

Multi-curvature catheter and medical device for surgery

A catheter delivery device having an improved mechanism for inserting a catheter into a blood vessel of a patient. The catheter delivery device includes at least: a body including a delivery path of a catheter; a pair of feeders having grippers located on the delivery path of the body and are configured to grip and release the catheter; and a rotator configured to rotate the catheter gripped by the feeders. The feeders move from a grip position where the grippers grip the catheter to a forward position where the grippers advance in a state of gripping the catheter, from the forward position to a grip release position where the grippers release the catheter, from the grip release position to a backward position where the grippers retract in a state of releasing a grip on the catheter, and from the backward position to the grip position.

Catheter delivery device

An input synthesis apparatus according to the present invention includes: a first input unit which provides first rotational force; a second input unit which provides second rotational force equal to or different from the first rotational force; a gear unit which is engaged with the first input unit and the second input unit and synthesizes the first rotational force and the second rotational force; and an output unit which outputs resultant force of the first rotational force and the second rotational force, in which the gear unit sums up speeds or torque of the first rotational force and the second rotational force based on whether a rotation direction of the first input unit and a rotation direction of the second input unit are identical to each other.

Input synthesis apparatus

A gear system for combining inputs is provided. The gear system can includes: a first power source that generates a rotational force; a second power source that generates a rotational force identical to or different from the rotational force of the first power source; a third power source that generates a rotational force identical or different from the rotational forces of the first power source and the second power source; and a gear unit that generates a resultant output by combining the rotational forces from the first power source to the third power source, in which the gear unit generates a resultant output by combining torque of any two of the first power source to the third power source and combining a speed of the other power source. According to this configuration, it is possible to generate various outputs from various power sources having the same or different characteristics.
