The utility model discloses a catheter for treating urethral stricture relates to urology technical field, and the utility model discloses a branch pipe, one side of branch pipe is equipped with three cavity pipes, and the other end fixed of branch pipe is equipped with indirect cavity, and one side fixed connection of indirect cavity has the connecting hopper, one side fixed connection of connecting hopper has the transmission pipe and one end fixed connection of transmission pipe has the urine tube access end, the upper surface one side fixed of urine tube access end is equipped with the pilot soft block, the upper surface fixed connection of urine tube access end has the input pipe, and the input pipe is linked together with transmission pipe, the utility model provides a catheter for treating urethral stricture, and the design of urine tube opening is in the tip, solves the problem that the conventional catheter cooperates with the guide wire for the urethral stricture patient and is easy to angle, and the problem of difficult to place, makes the catheter can follow the guide wire and pass the narrow urethra, improves the success rate of placement, reduces the patient's pain and urethral injury.

The invention relates to the technical field of medical instruments for urinary surgery, and discloses an integrated visual urethrostenosis treatment device which comprises a nesting tube, a main drainage channel is formed in the outer side of the nesting tube, and a positioning auxiliary channel, a visual channel and a dosing flushing channel are sequentially formed in the nesting tube from left to right; a targeted adjusting mechanism is arranged in the drug delivery flushing channel and used for controlling the release amount of drugs, and a pressure reduction mechanism is arranged in the drug delivery flushing channel and used for adjusting the internal pressure intensity of the drug delivery flushing channel. By pushing and pulling the adjusting rod in vitro, power is transmitted to the adjusting ball through the rotating rod, the adjusting disc is driven to rotate, meanwhile, the adjusting groove is rotated to drive the sliding block and the blocking plate to do opening and closing movement, the exposure area of the micropore array is adjusted, targeted adjustment of the drug action range is achieved, the drug administration precision and efficiency are improved, and the treatment effect is enhanced.

The invention relates to the technical field of urethral dilators, and discloses an antibacterial urethral dilator integrated with a super-smooth guide wire guiding and lubricating system. The expansion mechanism is arranged on the handle and used for expanding the urethra, the expansion mechanism comprises a probe, the probe is fixedly connected to the bottom of the handle, the end, away from the handle, of the probe is fixedly connected with a conical head part, and hollow grooves are formed in the inner wall of the probe and the inner wall of the handle. According to the antibacterial urethral dilator integrated with the super-smooth guide wire guiding and lubricating system, the dilation mechanism is arranged, a hollow groove coaxially formed in a handle and the inner wall of a probe is communicated with a side through hole in a conical head piece, and the super-smooth front end of a super-smooth guide wire extends out of a probe path from the side direction and is matched with the scale tail end to monitor the depth in real time; the conical head piece gradually dilates the urethra, integrated coaxial operation of the ultra-smooth guide wire and the probe is achieved, traditional step-by-step displacement and false channel formation are avoided, the urethra stenosis dilation operation is simplified, bleeding and infection risks are remarkably reduced, and the urethra dilator is particularly suitable for tortuous urethra.

The invention relates to the technical field of dilators, in particular to a device for dilating a urethral stricture and assisting in indwelling a ureter. Comprising a holding handle, one end of the holding handle is provided with an expansion body, the bottom of the holding handle is detachably connected with a miniature water pump, the water outlet end of the miniature water pump is detachably connected with a liquid inlet pipe, the liquid inlet pipe is detachably connected with the expansion body, the water inlet end of the miniature water pump is connected with a water inlet pipe, the water inlet pipe is inserted into a water storage tank, and normal saline is placed in the water storage tank. A water outlet pipe is arranged on the expansion body, water in the expansion body flows back into the water storage tank through the water outlet pipe, the normal saline entering speed is larger than the backflow speed, stable expansion of the medical rubber layer can be achieved, the expansion volume can be accurately adjusted by controlling the conveying speed of the micro water pump, and the expansion state of the expansion body can be maintained; meanwhile, the temperature of normal saline can be prevented from rising, the mucous membrane is prevented from being scalded, and the expansion body can be always kept in a proper temperature range.

The application discloses a kind of treatment equipment for reducing postoperative positive margin of prostate radical resection, including injection device for injecting PSMA probe into body, PET / CT imaging device, near-infrared fluorescence imaging device and surgical robot, near-infrared fluorescence imaging device shows the fluorescence level of tumor tissue and normal tissue of the prostate of the patient injected with probe, and prostate tumor tissue is fluorescently imaged according to the fluorescence intensity of probe in urine.The treatment equipment of the application carries out fluorescent imaging on tumor tissue during resection, and accurately positions, and the tumor tissue is accurately resected under the fluorescence navigation of surgical robot, and postoperative positive margin rate is significantly reduced;After prostate radical resection is carried out using the treatment equipment of the application, the risk of biochemical recurrence of patient is significantly reduced and prognosis is good;Moreover, it can also avoid the complications such as erectile dysfunction, urinary incontinence, urethral stricture caused by intraoperative damage to nerve and vascular bundle, and significantly reduce the influence on the quality of life of patient after operation.
