[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] This utility model provides a novel urinary catheter, including a urinary catheter 1 for draining patient urine and facilitating the breaking up of patient stones, and a ureteroscopic holmium laser device for breaking up and removing patient stones. The urinary catheter 1 is provided with a balloon 2 for being inserted into the bladder and expanded by water or air to limit its position. The upper part of the balloon 2 is a lying B-shaped configuration, and the lower part of the balloon 2 is a conical configuration. The balloon 2 and the urinary catheter 1 are integrally formed. The front end of the urinary catheter 1 is provided with a urine outlet 11 for draining patient urine. The front end of the urinary catheter 1 is also symmetrically provided with two drainage holes 12. It also includes a guide wire 3, which can be inserted through the urinary catheter 1 to the desired stone breaking position.

[0025] The device can observe the stone site through X-ray contrast agent technology after the urinary catheter 1 is placed at the required treatment position of the patient, and after observation, the guide wire 3 is first extended out from the corresponding drainage hole 12 through the water injection port 14 and finally placed in the stone crushing position, and then the holmium laser equipment of the ureteroscope is entered into the required stone crushing position along the path of the guide wire 3 to crush and take out, which realizes the effect that the urinary catheter 1 can assist the holmium laser equipment of the ureteroscope to guide, and also avoids the occurrence of situations that the holmium laser equipment of the ureteroscope has a large contact with the patient to cause harm.

[0026] In the ureteroscopy lithotripsy surgery, the urinary catheter 1 can play a guiding role, which can serve as a guide path to help doctors smoothly insert the ureteroscope along the urethra and ureter to the position where the stone is located. Because the ureteroscope is relatively thin, it is prone to be affected by the physiological curvature of the urethra and ureter during insertion and difficult to insert, and the presence of the urinary catheter 1 is like a "track" that provides correct directional guidance for the ureteroscope, enabling doctors to more accurately and quickly deliver the stone crushing instrument to the stone site for stone crushing operation.

[0027] Meanwhile, during the stone crushing process, the urinary catheter 1 can also serve as an auxiliary channel for flushing stone fragments, and after the stone is crushed, physiological saline and other flushing liquids can be injected into the urinary system through the urinary catheter 1 to flush the stone fragments out of the body, avoiding the residue of the fragments in the urinary system and further reducing the risk of stone recurrence and urinary system infection.

[0028] The urinary catheter 1 is inserted into the bladder through the urethra, and has a hollow channel inside. When the urinary catheter 1 is placed correctly, the urine in the bladder will naturally flow along this channel, bypassing the complex physiological structures such as the urethral sphincter during normal urination, thus establishing a direct drainage path from the bladder to the outside of the body, enabling the urine to be smoothly discharged out of the body. The urinary catheter 1 can achieve continuous drainage of urine, keeping the bladder in a relatively low pressure state, which is very helpful for patients who are long-term bedridden or have urinary system diseases.

[0029] In a further preferred embodiment of the present application, the balloon 2 is located at the front end of the urinary catheter 1, the balloon 2 is in a contracted state before use, the upper part of the balloon 2 is in a lying B-shaped shape and the lower part is in a conical shape after water injection or inflation, and the upper part of the balloon 2 is provided with an inclined groove 21.

[0030] The device is used for fixing the catheter 1 in the patient's body to stabilize and limit the catheter 1, facilitating the discharge of urine and the lithotripsy operation, and facilitating the final flow of urine out of the liquid outlet 13, avoiding overflow and injury caused by a large contact area with the patient.

[0031] In the further preferred embodiment of the utility model, the end of the catheter 1 is provided with a tee pipe, and the end of the catheter 1 is provided with a liquid outlet 13, a water inlet 14 and a flushing medicine inlet 15.

[0032] After the catheter 1 is placed in the treatment position of the patient, the device can discharge urine through the liquid outlet 13, inject water into the catheter 1 through the water inlet 14, and inject medicine into the patient's body and flush the inside of the catheter 1 through the flushing medicine inlet 15.

[0033] In the further preferred embodiment of the utility model, the guide wire 3 can be extended and retracted from the corresponding drainage hole 12 through the water inlet 14.

[0034] The guide wire 3 can be extended and retracted from the corresponding drainage hole 12 through the water inlet 14 to guide the ureteral flexible mirror holmium laser equipment to the desired lithotripsy position, thereby achieving the lithotripsy effect.

[0035] In the further preferred embodiment of the utility model, the catheter 1 is made of a corrosion-resistant material.

[0036] The catheter 1 is prone to corrosion, which shortens the service life of the catheter 1 and requires regular replacement of the catheter 1, thereby increasing the patient's expenditure and economic burden. The corrosion-resistant design of the catheter 1 can prolong the service life of the catheter 1, avoid the pain caused by replacement of the catheter 1 for the patient, and solve the problem of short service life of the traditional medical catheter 1.

[0037] The above merely describes the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of claims of the present application.
