Visual urethra expansion bougic with epitheca capable of being torn open

Abstract

The invention discloses a visual urethra expansion bougic with epitheca capable of being torn open. The visual urethra expansion bougic comprises an expansion bougic body, a camera eyepiece and a water inlet, the tail of the expansion bougic body is provided with an imaging device, the imaging device is internally provided with a chargeable battery, the camera eyepiece is fixed below the imaging device through a movable clamping opening, the head of the expansion bougic body is provided with a camera objective lens, the camera lens is connected with the camera eyepiece through light-guide fibres, the water inlet is formed below the camera eyepiece, the water inlet is connected with a water outlet through a water inlet pipe, the outside of the expansion bougic body is provided with the epitheca capable of being torn open, and the tail of the epitheca capable of being torn open is provided with handles. By means of the visual urethra expansion bougic, urethral dilatation can be conducted under a safe state, operation can be conducted conveniently in a ward or an outpatient clinic, the cost is low, pre-operation preparation time is short, and urethra expansion and placement of a urethral tube can be integrated.

Description

technical field [0001] The invention relates to the field of minimally invasive surgical instruments in urology, in particular to a visible urethral expansion bougie with a tearable outer sheath. Background technique [0002] Clinically, urinary catheterization is a basic medical operation that every doctor must master. Defined as: Inserting a urinary catheter through the urethra into the patient's bladder to drain urine out of the body. In some cases, catheterization can be difficult. For example: urethral stricture, false urethra (repeated catheterization or medical manipulations lead to pitted blind end of the mucosa in the urethra, and it is easy to place the head of the catheter here during catheterization, resulting in catheterization failure, urethral injury and bleeding) . For this kind of problem, if the traditional urethral expansion bougie is used to explore, the chance is high, because the expansion is all based on the hand feeling, and the whole process canno...

AI Technical Summary

Problems solved by technology

For this kind of problem, if you use the traditional urethral dilation bougie to explore, it is very accidental, because the expansion is all based on hand feeling, and the whole process cannot be visual, which is easy to form a false tract or damage the urethra.

If ureteroscopy is used for exploration, it needs to be operated in the operating room, and the preparation time is long and the price is high

Under the monitoring of the ureteroscope, enter the bladder along the urethra, and insert a guide wire into the bladder. The guidance of the guide wire can avoid the false tract, but if there is urethral stricture, it is necessary to dilate the urethra with a fascial dilator with a gradually increasing diameter. , indwelling catheter, the process is more complicated
