Description

Technical Field

[0001] The invention relates to the technical field of prostatic urethra, in particular to a prostatic urethra dilation catheter capable of expanding the visual field and visualizing the prostatic urethra. Background Art

[0002] Prostatic hyperplasia is a very common disease in urology clinic and the most common disease in middle-aged and elderly men that can cause urination disorders. From a histological point of view, prostatic hyperplasia is manifested as hyperplasia of the prostatic stroma and glands. From an anatomical point of view, prostatic hyperplasia is manifested as an increase in prostate volume. From a symptom point of view, prostatic hyperplasia is mainly manifested as lower urinary tract symptoms. From the perspective of objective urodynamic examination, prostatic hyperplasia manifests as bladder outlet obstruction. The dilation catheter is used in the treatment of prostatic tissue dilation surgery to preserve the original organ and function, with minimal trauma and a high safety factor.

[0003] In the existing technology, the camera is placed in the catheter and moved forward along the catheter. Since the diameter of the camera is small, it is easy to bend when entering the catheter, which will cause the camera connecting line to bend; it needs to be taken out, and the camera connecting line needs to be reset and then inserted again, which wastes time and increases the risk factor. Then, the visible area of ​​the path of the catheter entering the human body during surgery is small. For example, when observing different positions, the catheter needs to be moved back and forth. If the path is wrong, it is easy to cause damage to the human body. Finally, the camera will be damaged when working for a long time. Since the camera is small and is mostly connected by welding, when the camera is damaged, the camera and the connecting line need to be replaced as a whole, resulting in a waste of resources. Therefore, we propose a prostate urethra dilation catheter that can expand the field of view and visualize the prostate. Summary of the invention

[0004] The object of the present invention is to provide a prostate urethra dilation catheter that can expand the visual field and visualize the prostate, so as to solve the problems raised in the above-mentioned background technology.

[0006] The camera assembly includes a mounting plate fixed to the inner wall of the catheter body, the outer wall of the catheter body is provided with a camera hole, a plurality of groups of blocks are fixed at equal intervals on the left side of the mounting plate, and the facing sides of every two groups of blocks are installed with a camera assembly, the main function of which is to facilitate the user to observe the situation inside the prostatic urethra.

[0007] Furthermore, the camera assembly includes four groups of slide grooves opened on the opposite sides of the two groups of blocks, the inner walls of the four groups of slide grooves are slidably connected with sliders, the ends of the four groups of sliders away from the blocks are connected to the same bottom plate, a camera base is fixed on the top of the bottom plate, a camera is fixed on the top of the camera base, and the camera is adapted to the camera hole.

[0008] Furthermore, a group of miniature telescopic rods are fixed to the bottom of the four groups of sliding blocks, and the bottoms of the miniature telescopic rods are connected to the mounting plate.

[0009] Furthermore, two groups of springs are symmetrically fixed to the bottom of the base plate, and one end of the two groups of springs away from the base plate is fixedly connected to the mounting plate.

[0010] Furthermore, the flushing assembly includes several groups of holes opened on the outer wall of the catheter body, a bottom end is fixed to the bottom of the catheter body, a first urinary catheter is fixedly connected to the top of the bottom end, several groups of connecting tubes are fixedly connected to the outer wall of the first urinary catheter at the several groups of holes, a flushing tube is connected to one end of the connecting tube away from the first urinary catheter, and a second urinary catheter is sleeved on the outer wall of the flushing tube.

[0011] Furthermore, a flushing cavity is provided at the bottom of the bottom end.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting the catheter body, the front capsule cavity, the rear capsule cavity, the camera assembly, the flushing assembly, etc., when using, the camera is installed on the mounting plate, because a number of camera holes are opened on the surface of the catheter body, so the camera can observe in the camera hole, which will not affect the doctor's risk during the operation. Then, when the catheter body is inserted into the patient's body, the first catheter and the second catheter will drain the patient's urine, and then the flushing assembly will start to operate, and use physiological saline for cleaning, so that it is clearer during the operation and will not affect the user's line of sight. Through the above design, the camera assembly can be quickly installed and used, reducing risks and making the operation smoother.

[0014] 2. By setting the catheter body, the front capsule cavity, the rear capsule cavity, the camera assembly, the flushing assembly, etc., when in use, when the patient's urine is discharged from the first catheter and the second catheter, physiological saline is injected into the catheter body for timely cleaning, and the camera in the camera assembly can be flushed at the same time. In addition, when in use, the two sets of springs and two sets of micro-telescopic rods at the bottom of the camera will be activated, and observation can be made from multiple angles, so that the user can more clearly understand the situation inside the patient's prostatic urethra and make adjustments in time. The above design can achieve rapid cleaning and installation of the camera assembly, and can also be adjusted from multiple angles, which is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS
