Technical field

The present invention relates to the technical field of medical equipment, in particular to a manual suprapubic bladder auxiliary compression device.

Background technique

Transurethral resection of bladder tumor is a type of bladder tumor in situ with a diameter of less than 5mm, extroverted carcinoma and inverted papillary carcinoma with a diameter of less than 5cm, and B1T2 stage invasive cancer.

At present, in clinical transurethral bladder tumor resection, the patient is in the upside-down lithotomy position when the cystoscope is used to cut the tumor. Therefore, the tumor on the anterior wall of the bladder is above, and the surgeon needs to press the skin above the symphysis of the patient with bare hands to make the tumor Exposure to the field of vision, but the surgeon’s hand is easily sore, and it is very difficult to perform cystoscopy with one hand. So at this time, another assistant is needed to press on the side, but he needs to communicate with the main knife from time to time to achieve cooperation, but his hands are still sore.

Therefore, there is an urgent need for a device that can replace the assistant while pressing the anterior bladder wall above the pubic symphysis under the control of the surgeon.
