Sample removal device for transurethral intra-cavity surgery

Abstract

The invention relates to a sample removal device for transurethral intra-cavity surgery. The sample removal device is characterized in that the sample removal device comprises a sample bag with a plurality of decomposition bags and a pushing and cutting pipe, two semicircular elastic edge threads are arranged at a sample bag opening in the top end of the sample bag, pulling ropes are mounted in the two semicircular elastic edge threads in a penetrating manner, and a fishing thread cutting screen is horizontally at the joints of the decomposition bags and the sample bag. The sample removal device is scientific and reasonable in design, the sample bag is matched with the pushing and cutting pipe, a whole bladder tumor can be closely and controllably taken out in a block divided manner afterbeing excised, diffusion of sample tissues caused by exposure and uncontrollable crack is avoided, recurrent risks of the bladder tumor are reduced, and the sample removal device is convenient to operate and wide in application range.

Description

technical field [0001] The invention belongs to the field of medical supplies, and relates to an instrument for transurethral intracavity surgery, in particular to a specimen taking device for transurethral intracavity surgery. Background technique [0002] Bladder tumor is the most common malignant tumor in urology. With the rapid development of minimally invasive surgery, large international medical centers gradually adopt en bloc resection of bladder tumor as a new treatment method for bladder tumor, which can not only reduce tumor recurrence, but also The base of the tumor is kept intact, and the accurate judgment of the pathological grade of the tumor invasion depth can be used to more accurately guide the next treatment plan, which is more conducive to the judgment of the prognosis of the disease. [0003] At present, large specimens after en bloc resection by minimally invasive surgery cannot be removed from the urethra, especially for male patients. There is no ideal...

AI Technical Summary

Problems solved by technology

[0003] At present, large specimens after en bloc resection by minimally invasive surgery cannot be removed from the urethra, especially for male patients. There is no ideal specimen extraction device at present. The stone extraction basket used at this stage is easy to forcibly squeeze and shred the specimen, which increases tumor risk. Risks such as fragmentation and urethral implantation and metastasis, and the inability to take out larger tumor specimens has greater limitations
