A tumor receiving and pulverizing device for transurethral bladder tumor resection

Abstract

The invention discloses a tumor storage and crushing device for transurethral bladder tumor resection, comprising a cutting mechanism that enters the bladder through the urethra, an operating rod body is also arranged in the cutting mechanism, and a communication mechanism for externally connecting a water source is arranged inside the operating rod body. The end of the operation rod body is provided with a tumor storage mechanism, the tumor storage mechanism is communicated with the communication mechanism, and a tissue crushing operation channel is arranged between the communication mechanisms, and also includes a tissue crushing mechanism acting on the tumor, and the tissue crushing mechanism is located in the operation rod body. The pulverizing mechanism includes a tissue pulverizing drive wire. The operating rod body is provided with a tissue pulverizing operation channel. The tissue pulverizing driving wire moves relatively with the tissue pulverizing operating channel. The surface of the tissue pulverizing driving wire is provided with several evenly spaced protrusions along the axial direction to avoid pulverization. When the tissue crushing mechanism shakes and affects the crushing operation, the device can wrap, crush and extract the resected tumor to reduce the risk of tumor implantation and metastasis.

Description

technical field [0001] The invention relates to an operation device, in particular to a tumor storage and pulverization device for transurethral bladder tumor resection. Background technique [0002] Bladder cancer is one of the common tumors in urology. Worldwide, the incidence of bladder cancer ranks 12th among cancerous diseases, and the incidence rate of bladder cancer ranks 6th in men. Transurethral resection of bladder tumors is the gold standard for the treatment of non-muscle-invasive bladder cancer. Due to its advantages of minimal invasiveness, fewer complications, and faster postoperative recovery, this procedure is widely used, and laser is the most commonly used resection method. means. If the bladder tumor is found to be small and pedunculated during the operation, laser can be used to directly resect it from the base. If the tumor is large, even if the pedicle is small, it should not be resected directly from the base to avoid bladder perforation. It should ...

AI Technical Summary

Problems solved by technology

[0003] During the surgical operation, after the tumor is resected en bloc from the base, the tumor drifts in the bladder cavity filled with irrigation fluid, which may lead to the implantation and metastasis of bladder tumors, which violates the principle of tumor-free surgery

What's more serious is that when the tumor is too large to be resected en bloc from the base and needs to be resected from the top of the tumor in layers, the risk of tumor implantation and metastasis is higher, and for a tumor that is too large, it needs to be pulverized Take it out, because the rotating tissue crushing mechanism needs to enter the bladder cavity through the external opening of the urethra, it is small in size and insufficient in rigidity, and it is easy to cause serious shaking during the crushing process, which will affect the operation of the rotating tissue crushing mechanism
