Description

Pullback device {PULLBACK DEVICE}

The present invention relates to a pullback device.

In order to diagnose and treat the lesions of the human body, medical images are required in many medical fields such as digestive system, heart and neuron system, skin system, and eye system.

In this case, for example, in the case of a blood vessel system, techniques for imaging blood vessels to detect a blood vessel state include Intravascular Ultrasound (IVUS) image acquisition technique using ultrasound, Optical Coherence Tomography (OCT) image acquisition technology, and photoacoustic (PA) image acquisition technology using light absorption characteristics.

These blood vessel imaging techniques insert an intracavitary catheter to image in real time the endothelium and deep portion of the inner wall of the blood vessel and image the shape and structure of the region of interest (ROI).

At this time, in order to visualize the blood vessels, the catheter moves intravascularly and performs intravascular scanning.

Here, the catheter must be moved in the longitudinal direction of the blood vessel for intravascular scanning, and the catheter must be moved at a constant force and speed in order to minimize damage to the inner wall of the blood vessel.

Accordingly, a device for pulling the catheter at a constant force and speed has been developed in various ways. As a part of this research, Korean Patent Registration No. 10-1487894 filed on March 23, 2013, 01, 23, hereinafter referred to as " prior art ").

In this case, the conventional technique pulls the medical cable at a constant speed using a driving motor. However, if the catheter is inserted into the inner wall of the blood vessel, There is a problem in that it is not easy to acquire a precise image in all directions in the blood vessel because only an image corresponding to a certain angle can be acquired.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a technique for minimizing damage to a blood vessel during scanning, which enables scanning in all directions in an intravascular direction.

According to an aspect of the present invention, there is provided a pullback device including a first motor, a catheter tube including an optical fiber and an electric signal line inserted through the catheter tube, A rotation driving module including a rotating part rotating; A rectilinear driving module coupled to a second motor and to one side of the rotational driving module, the rectilinear driving module including a motion inducing part for guiding the movement of the rotational driving module in the longitudinal direction of the catheter tube according to the operation of the second motor; And a control module for controlling the rotation driving module and the linear driving module.

In this case, the rotation unit may include: a first rotationally coupled portion that allows the optical fiber to pass therethrough and is in contact with the electrical signal line; A second rotationally coupled portion through which the optical fiber passes; And a connection part through which the optical fiber passes and in which the first rotation coupling part and the second rotation coupling part are rotatable, and the rotation drive module includes a structure for fixing the first motor and the rotation part As shown in FIG.

The rotation part may include a second rotation part at one end of the first rotation coupling part and the second rotation part may be connected to a first rotation part provided at one end of the first motor through a fan belt, The catheter tube can be rotated by operation of the first motor.

The catheter tube is also formed from a catheter head inserted into a blood vessel to illuminate light and ultrasound signals, the catheter tube including an optical fiber and an electrical signal line therein, the optical fiber being located in the center axis of the catheter tube .

The first rotationally coupled portion may include a connecting member for maintaining electrical contact of the electric signal line when the first rotating portion rotates.

At this time, the first rotating coupling portion, the second rotating coupling portion, and the connecting portion are formed with hollows for passing the optical fiber on the same straight line. When the catheter tube is rotated by the operation of the first motor, The first rotating coupling portion, the second rotating coupling portion, and the connecting portion can guide the rotation of the optical fiber while maintaining the parallelism of the optical fiber.

As described above, the present invention has the following effects.

First, it can be rotated about 360 degrees in all directions and move in the longitudinal direction of the catheter tube. Thus, it is possible to acquire three-dimensional image of the inner wall of the blood vessel. In addition, The catheter is moved to the inner wall of the vessel so that the catheter can be moved by minimizing the damage to the inner wall of the vessel by reducing the friction through rotation.

Second, since the rotation driving module and the linear driving module can be controlled when the inside of the blood vessel is moved due to the contraction of the blood vessel, the rotation speed of the catheter and the moving speed of the catheter can be controlled, Catheter movement for accurate acquisition of the image is possible even with minimal damage, and the movement of the catheter for acquisition of the intravascular image can be made more secure.

Third, the hollows formed in the first rotating coupling portion, the second rotating coupling portion, and the connecting portion constituting the rotating portion are positioned on the same straight line so as to guide the rotation of the optical fiber so that the parallelism of the optical fibers passing through the hollow is maintained, At this time, the first rotationally coupled portion may be connected to the electric signal line in the rotating catheter tube when the catheter is rotated by the first motor operation, thereby enabling input and output of the electric signal to the ultrasonic transducer located at one end of the catheter.

Fourth, by preventing the optical fiber from being bent during the rotation of the catheter through the arrangement of the above-described rotation unit, the optical fiber and the electric signal line are prevented from being damaged by the rotational force, Can be increased.
