Bladder tumor specimen extractor

Abstract

A bladder tumor specimen extractor comprises an automatically opened and closed net bag device, wherein the automatically opened and closed net bag device comprises a titanium alloy rod and a memory alloy rod, two ends of the memory alloy rod are connected with two ends of the titanium alloy rod, and the titanium alloy rod and the memory alloy rod form an annular structure. A heating ring is installed on the memory alloy rod. When the memory alloy rod and the titanium alloy rod which are in an oppositely folded state extend into the inner side of the bladder, the heating ring can heat the memory alloy rod, and the folding state is changed into an unfolding state when the memory alloy rod is heated, so that the annular structure formed by the memory alloy rod and the titanium alloy rod is opened to facilitate bladder sleeving by a specimen bag, the heating ring stops heating, then the memory alloy rod is slowly recovered to the folding state, and the annular structure formed by the memory alloy rod and the titanium alloy rod is recovered to the folding state to facilitate bladder taking out.

Description

technical field [0001] The invention relates to a taker, more precisely a bladder tumor specimen taker. Background technique [0002] The commonly used surgical method for bladder tumors is transurethral resection of bladder tumors. The traditional surgical method is to cut the tumor into pieces and wash it out. The disadvantage is that the fragmented specimen loses the complete shape of the tumor, and the base of the tumor cannot be identified, making it difficult to determine the tumor. The depth of invasion is difficult to judge the stage of the tumor. In recent years, en bloc resection of bladder tumors has been used to completely remove the tumor, which is convenient for pathologists to grasp the pathological staging and grading of tumors as a whole, and is conducive to formulating clinical treatment plans. However, when the volume of a completely resected tumor is too large, it cannot be extracted by a conventional irrigator, and there is currently no ideal specimen e...
