TECHNICAL FIELD

[0001] The application belongs to the technical field of bladder tumor surgery, and particularly relates to a bladder tumor specimen extractor. BACKGROUND

[0002] Bladder tumor is the most common tumor in the urinary system, most of which are transitional epithelial cell carcinomas, and most of them occur in the lateral wall and posterior wall of the bladder, followed by the trigone and top, and the occurrence can be multicentric, and bladder tumor can be accompanied by renal pelvis, ureter and urethral tumor successively or simultaneously, in foreign countries, the incidence of bladder tumor is only second to prostate cancer in male urogenital tumors, ranking the second; in China, it ranks the first, and the male incidence is 3-4 times that of the female, and the age is mostly 50-70 years old.

[0003] In the transurethral bladder tumor electrocision surgery, an electrocision mirror or a laser mirror is usually placed into the bladder through the urethra to complete tumor resection under the endoscopic vision, and if a larger tumor is encountered during the surgery, the tissue is first cut into small pieces after resection, and then taken out with a foreign body forceps, but this way not only brings inconvenience in sampling, but also causes the tissue fluid and plasma in the bladder tumor to remain in the bladder, and the reprocessing is still inconvenient, therefore, a bladder tumor specimen extractor is urgently needed to solve the above problems.
