Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a device for indwelling a body for improving urination (Japanese Patent Application No. 5-52844) safely and reliably in the affected area of the urethra, preventing movement during the indwelling, and inserting and removing. The present invention relates to embodying an insertion device and an insertion method of a device for indwelling in the body for improving micturition that can eliminate the pain of the patient without damaging the urethra.

2. Description of the Related Art As a conventional method for inserting an indwelling device for improving urination, a device for indwelling urination is positioned in the urethra of the prostate using forceps or the like under fluoroscopy, under ultrasonic monitoring. There are methods such as using a forceps to position the indwelling device for improving urination in the prostatic urethra, and positioning the indwelling device for improving urination in the urethra of the prostate with forceps etc. under direct endoscopic view. It was That is, in the method, a contrast agent is injected into the urethra to image the urethral prostatic region, and an indwelling device for improving micturition is inserted while observing the prostatic urethra.
In this method, an indwelling device for improving urination is inserted while drawing a longitudinal cross-sectional image of the prostate by ultrasonic tomography (transmural or transrectal). In this method, an endoscope is inserted into the urethra to confirm the position of the sperm, and an indwelling device for improving micturition is positioned at the distal end of the sperm (proximal end of the external sphincter). In either method, it is essential to accurately position the peripheral side of the body of the indwelling instrument for improving urination at the apex of the prostate (located at the proximal end of the external urethral sphincter). When the distal end of the indwelling device for improving micturition is shifted to the head side from the sphincter, the micturition efficiency is not improved, and when it is shifted to the caudal side (distal), urinary incontinence occurs Because.

[0003]

Among the conventional methods for inserting an indwelling device for improving micturition in the body, it is difficult to identify the apex of the prostate gland (located at the proximal end of the external urethral sphincter) by X-ray fluoroscopy. . In the ultra-short-wave tomography of the above method, it is difficult to identify the prostate apex because the angle between the prostate apex and the ultrasonic beam is tangential. In the endoscopic method, the urethra is greatly curved distal to the external sphincter muscle, so it is difficult to directly look at the distal end of the sperm while grasping the indwelling device for improving micturition with forceps. There was a drawback. That is, in the conventional method for inserting an indwelling device for improving urination, the insertion means is also complicated, and in order to place the device in the accurate position of the urethra (immediately above the urethral sphincter, that is, the proximal end), high skill and skill are required. Was there. It is an object of the present invention to simplify the insertion operation and maintain the accuracy of the insertion position.

SUMMARY OF THE INVENTION The insertion device of the indwelling device for improving urination according to the present invention has a front end that facilitates insertion, and has a spherical obstruction so that the urethra is not damaged and a wire passes through the rear end. A straight pipe or a curved pipe terminated with a lid having a hole is branched and connected with a hot water injection pipe with one end opened, and a hot water outlet consisting of a large number of pores penetrating the pipe wall is provided at the center of the pipe, and thereafter. A main body having a first elongated hole penetrating the pipe adjacent to the one side and passing through the center of the pipe, and a second elongated hole penetrating the lower wall of the pipe in the same row as the first elongated hole further adjacent to the first elongated hole, A V-shaped spring hook having a hook portion and a protrusion portion is supported by a pin, and an actuator enclosed in the main body by fixing a wire to the other end, a fixed handle fixed to the main body, and a fixed handle on the fixed handle. It is rotatably mounted at a fulcrum and has a leaf spring attached to one end and a wire that passes through the through hole at the other end. And a movable handle which is fixed to over.

The body indwelling device for improving urination (FIG. 5) is wound tightly and deformed into a thin shape (FIG. 6), and the insertion end of the body indwelling device for improving urination is inserted into the hook portion of the spring hook. (Fig. 7), then insert the body into the urethra from the front end and determine the position of the protrusion by palpation of the rectum to determine the indwelling position and inject hot water from the opening of the hot water injection tube. When the indwelling device for improving urination returns to its original shape, push the movable handle to pull the hook portion and the protrusion of the spring hook into the tube and remove the body.

[0006]

[Operation] Attach the indwelling device for improving urination to the insertion device of the indwelling device for improving urination (Fig. 7) and insert it into the urethra (Fig. 9). After returning to the original shape, if the movable handle is pushed against the grip of the fixed grip and the leaf spring, the actuator is pulled through the wire and moves toward the rear end. Since the elastic spring hook attached to the actuator slides while contacting both V-shaped slopes of the V-shaped inclined surface with the edge of the elongated hole, the hooks and protrusions of the V-shaped shoulders are drawn into the pipe, When the main body is pulled out, only the indwelling device for improving urination can be placed in the urethra without hindering the passage of the indwelling device for improving urination.
