Description

Fine steering control catheter using digital camera and insertion tube of drug/medical device

The present invention relates to a catheter, which includes a digital camera, a drug/medical device insertion tube, and an optical fiber, and is treated while checking the affected area through a digital camera under irradiation of light by optical fiber, and a digital camera capable of controlling the fine steering of the shaft; It relates to a micro-steer control catheter using a drug/medical device insertion tube.

A catheter, in a broad sense, refers to a tube inserted into the body for diagnosis or treatment.

Such a catheter is a catheter having a photographing means for observing the inside in order to check the state of the internal organs, a catheter having a drug supply pipe to supply drugs to the internal organs, and the adhesion site by irradiating a laser to the internal organs and a catheter that burns and removes a tumor, a catheter with a balloon that can widen the affected area narrowed by adhesions and stenosis, and a rotatable catheter with a curved end for the treatment of a herniated disc, etc.

As a technology related to such a catheter, "Steerable catheter" (US Patent No. 6,146,355, hereinafter 'Patent Document 1') 4 and 5 pages 2A, 2B, a wire for rotating a tube and a shaft for supplying a drug, Disclosed is a catheter provided with a driving device for pulling the wire to rotate the shaft.

In addition, in Patent Document 1, the doctor in charge of the procedure cuts the side of the patient's tailbone, controls the shaft of the catheter with a drive device, and inserts it into the patient's spine through the incision to supply drugs or medical devices to the desired point. A catheter is disclosed that treats the affected area by inserting it or removes the adhesions by rotating the tip of the shaft left and right.

In general, visualization equipment such as MRI, fluoroscopic X-ray, and radiographic imaging equipment using C-arm are used to reach the catheter to the affected area, but visualization equipment commonly used in surgery has poor visualization performance for soft tissues in the human body. There is a low disadvantage, the movement of the patient during the procedure or the size or shape of the passage through which the shaft is inserted for each patient is different, so there is a big problem in the risk of misalignment.

Therefore, in addition to the catheter having a shaft rotated by a wire, an endoscopic catheter was separately inserted to check the internal state, but as two catheters are inserted in a cramped space, difficulty in moving the shaft occurs, and the procedure of the catheter There was a problem in that it was difficult to stimulate or supply drugs by rotating the tip.

As a technology for solving this problem, in Figure 5 on page 4 of "Endoscope for direct visualization of the spine and epidural space" (US Patent No. 5,396,880, hereinafter 'Patent Document 2'), a wire for steering is inserted into the shaft. A catheter equipped with a hole, a hole into which an optical fiber bundle for images and lighting is inserted, and a hole into which an iron rod is inserted to enhance the straightness of the shaft is disclosed.

However, Patent Document 2 has a problem in that the inside of the optical fiber bundle flows together in the process of bending the tip of the shaft according to the movement of the wire, so that the inside cannot be photographed and the image quality is low.

Furthermore, in the prior document 2, when each of the holes for drug injection and medical device insertion are formed, at least five holes must be formed in the shaft, and the diameter of the shaft becomes large, and as such, the diameter of the shaft is large. There was a problem in that it was not suitable for disc treatment and a procedure in which a shaft is inserted into a narrow space as it loses.

As a technology to solve this problem, in Figure 5 on page 13 of "A catheter using an optical fiber and a camera (Republic of Korea Patent Publication No. 10-1195997, hereinafter 'Patent Document 3'), a hole into which an optical fiber for illumination is inserted, and a camera are A catheter equipped with a cap having a hole to be inserted and a hole for inserting a drug infusion tube, a hole in which a wire for steering is inserted into the shaft, and a shaft having a hollow part for insertion of an optical fiber, a camera cable, and a drug infusion tube is disclosed. have.

However, although Patent Document 3 provides a clear internal image based on a shaft steered through a camera inserted into the front end surface of the cap, it is vulnerable to electrostatic stimulation, so there is a problem that needs to be supplemented.

In the clinical field where surgery is performed, it is necessary to not only inject drugs but also to use medical devices such as forceps and balloons. In order to add one more large medical device insertion tube, the diameter of the shaft increases, so there is a problem that the shaft is not suitable for a procedure in which the shaft is inserted into a narrow space.

As a technology related to the catheter shaft steering stop, "Catheter with electrode tip having asymmetric left and right curve configurations" (US Patent No. 5,273,535, hereinafter 'Patent Document 4') 3 pages 2A and 2B, "Steering mechanism for bi -Directional catheter (US Patent No. 9,861,790, hereinafter 'Patent Document 5') of Figure 6, Figure 9, Figure 8, Figure 11A and 11B, Figure 12, Figure 17 and Figure 18, "Adjustable catheter (Korean Patent Publication No. 10- In 2018-0112355 No., hereinafter, 'Patent Document 6') on page 16, Fig. 9 and page 17, Fig. 10 discloses a technique of pulling a steering wire to rotate the shaft and then fixing it.

When the steered shaft is fixed by this steering stop technology, it is impossible to fine steer the shaft by adjusting the steering control unit. There was a problem that the steered shaft fluctuated according to the Giga spacing.

US Patent No. 6,146,355 (November 14, 2000) U.S. Patent No. 5,396,880 (Mar. 14, 1995) Republic of Korea Patent Publication No. 10-1195997 (2012.10.24.)
