[0001] The invention relates to the field of visual electrical stimulation catheters, and in particular to a visual electrical stimulation catheter. Background Art

[0002] There are currently no catheters on the market that can be used for bladder, nasal cavity, throat, stomach, heart and lungs, and other human tissues, for analgesia, anti-inflammatory, promotion of local blood circulation, etc., or for narrow parts of the human body, or for guiding instruments into cavities or tissues. Electrode, injection, and suction functions can be visualized electrode catheters, so we have developed monopolar visualization, extraction and injection, electrical stimulation and other multifunctional electrode catheters, which can visualize the affected area for precise electrical stimulation treatment, and can also extract or inject fluid for flushing, etc. It can be used to treat bladder dysfunction and is mainly used to treat bladder dysfunction, such as urinary incontinence and urinary retention. It helps restore the normal function of the bladder by electrically stimulating the bladder nerves and muscles, and transmits low-intensity currents to the nerves and muscles around the bladder through electrodes to stimulate nerve signal transmission and muscle contraction;

[0006] Furthermore, the outer side wall of the three-way joint is integrally formed with a liquid extraction and injection port.

[0007] Furthermore, the outer side wall of the soft catheter is integrally formed with a liquid inlet and outlet hole.

[0008] Furthermore, an annular cavity is provided inside the one-way silicone valve, and the annular cavity is communicated with the inner side of the one-way silicone valve. A plurality of guide grooves are provided on the inner lower surface of the annular cavity.

[0009] Furthermore, a circular ring is provided on the inner side of the annular cavity, and a plurality of rotating connectors are fixedly connected to the inner side of the circular ring. The upper surface of the rotating connector is rotatably connected to a traction rod via a rotating shaft, and one end of the traction rod away from the rotating connector is rotatably connected to the upper surface of the wedge-shaped sealing flap via a rotating shaft.

[0010] Furthermore, an arc-shaped groove is provided on the inner side of the circular ring, a stopper is integrally formed on the inner side of the annular cavity and located inside the arc-shaped groove, and a spring is fixedly connected between the stopper and the arc-shaped groove.

[0014] Beneficial effects: The electrode ring is connected to one end of the wire, and the other end of the wire is connected to the socket and buried in the inner wall of the soft catheter, which does not affect the middle channel. The one-way silicone valve is normally closed. When an object is inserted, the opening will open, and when the object is taken out, the opening will close. When extracting liquid, the liquid enters from the liquid inlet and outlet hole through the soft catheter and then flows out from the liquid extraction and injection port of the three-way joint. If it is injection, it enters from the liquid extraction and injection port and flows out through the liquid inlet and outlet hole. Insert the soft USB endoscope into the one-way silicone valve hole and directly insert it onto the lens (reaching the bottom). Find the affected area for operation. When extracting or injecting liquid, the soft USB endoscope can be pulled out, which can increase the flow rate, and then realize the multifunctional electrode catheter such as monopolar visualization, extraction and injection, electrical stimulation, etc., which can visualize the affected area for precise electrical stimulation treatment, and can extract or inject liquid for flushing; avoid long-term dependence on drugs, non-invasive or minimally invasive, non-invasive treatment is non-invasive, and invasive treatment is less invasive, and the stimulation intensity and frequency can be adjusted according to the patient's condition;

[0015] Under normal conditions, multiple wedge-shaped sealing flaps block the inner side of the one-way silicone valve to close it. After the soft USB endoscope is inserted, the multiple wedge-shaped sealing flaps are squeezed to shrink toward the inside of the annular cavity, which will open the wedge-shaped sealing flaps and squeeze the spring one to shrink. The reaction force after the spring one is compressed and squeezed will clamp the stability of the soft USB endoscope after insertion through the wedge-shaped sealing flaps, ensuring the stability of the soft USB endoscope after insertion and preventing it from falling off. This avoids the problem of the soft USB endoscope in the prior art being easily loosened and detached when inserted and used, and thus better endoscopy can be achieved.

[0016] When the soft USB endoscope is in use, the one-way silicone valve, three-way connector and soft catheter are inserted through the sleeve, and the endoscope probe is guided into the inside of the lens. When in use, the handheld rotating sleeve is rotated to control the retraction of the traction rope, thereby pulling the endoscope probe to move and change the inclination to facilitate endoscopy at different angles. The handheld sleeve can be rotated as a whole to adjust the endoscopy direction of the endoscope probe. By adjusting the endoscopy angle of the endoscope probe, the endoscopy range can be wider and more comprehensive, which can better assist the use of the device to find the affected area for precise electrical stimulation treatment.

[0029] The outer wall of the three-way joint 2 is integrally formed with a liquid extraction and injection port 201;

[0030] The outer wall of the soft conduit 3 is integrally formed with a liquid inlet and outlet hole 301;

[0031] The electric stimulation catheter is composed of an electrode ring 5 connected to one end of the wire 6, and the other end of the wire 6 is connected to the socket 7 and buried in the inner wall of the soft catheter 3 without affecting the middle channel. The lens 4 is inserted into the electrode ring 5 and fixed on the soft catheter 3. The three-way connector 2 is inserted into the other end of the soft catheter 3. The one-way silicone valve 1 is sleeved on the head of the three-way connector 2. The one-way silicone valve 1 is in a normally closed state. When an object is inserted, it will open and close when the object is withdrawn. When liquid is drawn, the liquid enters from the liquid inlet and outlet hole 301 through the soft catheter 3 and then flows out from the liquid extraction and injection port 201 of the three-way connector 2. If liquid is injected, it enters from the liquid extraction and injection port 201 and flows out through the liquid inlet and outlet hole 301;

[0032] Use the soft USB endoscope 8: insert the soft USB endoscope 8 into the hole of the one-way silicone valve 1, straight into the lens 4 (reaching the bottom), find the affected area to operate, and pull out the soft USB endoscope 8 when extracting or injecting fluid, which can increase the flow rate;

[0033] Then, a multifunctional electrode catheter with monopolar visualization, fluid extraction and injection, electrical stimulation, etc. was realized. The affected area can be visually located for precise electrical stimulation treatment, while fluid extraction or injection for flushing can also be performed.

[0034] like Figure 5 and Figure 6 As shown, an annular cavity 9 is provided inside the one-way silicone valve 1, and the annular cavity 9 is connected to the inner side of the one-way silicone valve 1. A plurality of guide grooves 10 are provided on the inner lower surface of the annular cavity 9. A guide column 11 is slidably connected to the inner side of the guide groove 10, and a wedge-shaped sealing flap 12 is fixedly connected to the top of the guide column 11.

[0036] An arc groove 16 is formed on the inner side of the circular ring 13, and a stopper 17 is formed integrally on the inner side of the annular cavity 9 and located inside the arc groove 16. A spring 18 is fixedly connected between the stopper 17 and the arc groove 16.

[0037] The upper surface of the wedge-shaped sealing flap 12 is a silicone cushion. Under normal conditions, when the soft USB endoscope 8 is not inserted into the soft catheter 3 through the one-way silicone valve 1, under the push of a single spring 18, multiple wedge-shaped sealing flaps 12 will fit together and block the inner side of the one-way silicone valve 1 to close it. When the soft USB endoscope 8 is inserted, the bottom end contacts the inclined surface of the wedge-shaped sealing flap 12, which squeezes the multiple wedge-shaped sealing flaps 12, thereby squeezing the multiple wedge-shaped sealing flaps 12 to shrink toward the inside of the annular cavity 9. At this time, the guide column 11 will move along the The guide groove 10 slides, and at this time, under the linkage of the traction rod 15, the ring 13 will be pushed to rotate, and the arc groove 16 will slide along the block 17 and squeeze the spring 18 to contract, and the reaction force of the spring 18 after being compressed and squeezed will clamp the soft USB endoscope 8 after insertion through the wedge-shaped sealing flap 12 to ensure the stability of the soft USB endoscope 8 after insertion, and it is not easy to fall off, thereby avoiding the problem of the soft USB endoscope 8 in the prior art that it is easy to loosen and detach when inserted and used, and then better endoscopy can be achieved.

[0039] The bottom end of the sleeve 803 is symmetrically fixedly connected with a second rotating connector 804, and the opposite sides of the two second rotating connectors 804 are both rotatably connected with a third rotating connector 805 through a rotating shaft, and the bottom of the third rotating connector 805 is fixedly connected to the upper surface of the endoscope probe 802;

[0040] The top of the sleeve 803 is rotatably connected to a rotating sleeve 806 via a rotating shaft, and a reeling groove 807 is integrally formed on the outer wall of the rotating sleeve 806. A wire groove 808 is integrally formed inside the sleeve 803, and a traction rope 809 is arranged inside the wire groove 808.

A second spring 810 is sleeved on the outer wall of the traction rope 809, and the two ends of the second spring 810 are respectively fixedly connected to the opposite sides of the endoscopic probe 802 and the sleeve 803;

[0041] When the soft USB endoscope 8 is in use, the one-way silicone valve 1, the three-way connector 2 and the soft catheter 3 are inserted through the sleeve 803, and the endoscope probe 802 is introduced into the inner side of the lens 4. When in use, the handheld rotating sleeve 806 is rotated to control the winding of the traction rope 809, thereby pulling the endoscope probe 802 to move and change the inclination to facilitate endoscopy at different angles. The handheld sleeve 803 can be rotated as a whole to adjust the endoscopy direction of the endoscope probe 802. By adjusting the endoscopy angle of the endoscope probe 802, the endoscopy range can be made wider and more comprehensive, and the auxiliary device can be better used to find the affected area for precise electrical stimulation treatment.

[0042] Working principle: When treating bladder dysfunction, the patient first goes to the bathroom to urinate on his own. After the patient is anesthetized on the operating table, the doctor inserts the soft USB endoscope 8 into the soft catheter 3 to the bottom (lens 4 position); connects the injection tube or the extraction tube at the extraction and injection port 201; and connects the soft USB endoscope 8 to the computer (display); the doctor inserts the soft catheter 3 into the urethra, and operates while watching to find the disease point or treatment point; extracts excess urine, and then injects electrode liquid or saline (increases the conductive effect); inserts the positive electrode wire into the socket 7, and the other end is connected to the electrode host; the negative electrode sheet is attached to the hand; the host program is started for electrical stimulation treatment; the electrical stimulation treatment is over, and this method can adjust the stimulation intensity and frequency according to the patient's condition by controlling the electricity.
