The present invention relates to an image processing system for a catheter operation. One embodiment comprises: a storage unit for at least temporarily storing a plurality of candidate routes on which a guide wire can proceed on a changing route caused by vascular bifurcations while proceeding from a first point by using a blood vessel image; and a processor for selecting, from an image inputted while an operation proceeds, at least one route corresponding to the current shape of the guide wire on the basis of a similarity comparison between the current shape of the guide wire and each of the plurality of candidate routes.

Apparatus and method for evaluating proceeding route of guide wire

The present invention provides a medical robot which is hygienic and capable of precisely transferring a catheter, a driving device mounted on the medical robot, and a roller module mounted on the driving device. The roller module includes: a driving unit; and a roller unit rotated about the vertical axis by the driving unit, wherein the roller unit includes at least one roller and at least one shaft independently coupled to the at least one roller of the roller unit and rotated by the driving unit, wherein at least one groove is formed on the at least one roller of the roller unit and at least a part of the at least one shaft of the roller unit is disposed on the at least one groove.

Roller module for medical robot, driving device for medical robot, and medical robot

The present invention is advantageous in that the shape of the catheter can be sensed by detecting the position of bending of the catheter body, the direction thereof, the angle thereof, and the curvature thereof through a triplet calculation of information regarding three wavelengths that have undergone a transition along respective FBGs provided on three optical cores.

Catheter for sensing shape and contact force by using FBG optical fiber and catheter system therefor

The present invention is a system for three-dimensionally mapping a heart, comprising: a mapping catheter including three or more optical cores each of which has a plurality of FBGs disposed in the lengthwise direction of a catheter body, and a plurality of electrodes disposed in the lengthwise direction of the catheter body and exposed on the outer circumferential surface of the catheter body, wherein the electrodes make contact with the inner wall of the heart; and a mapping processor for calculating coordinates of the FBGs by wavelength information of reflected light received from the three or more optical cores, and calculating coordinates of the electrodes from the coordinates of the FBGs so as to build a three-dimensional shape of the heart by using a sample point at which the plurality of electrodes make contact.

System and method for three-dimensionally mapping heart by using sensing information of catheter

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.
