Bladder tumor en-block whole-block excision device based on resectoscope

Abstract

The invention discloses a bladder tumor en-block whole-block excision device based on a resectoscope, and relates to the technical field of medical instruments, and the technical scheme is characterized in that the bladder tumor en-block whole-block excision device comprises a control box body, and an observation device, an electric control device, a water volume adjusting device and a tumor supporting device are arranged in the control box body; the water volume adjusting device comprises a water inlet adjusting valve, a water outlet adjusting valve, a water inlet pipe, a water outlet pipe, an annular collecting bin and a separating device. According to the resectoscope bladder tumor en-block whole-block excision device, normal saline can be injected into the bladder through the water volume adjusting device, so that the bladder filling degree is maintained for a long time under the condition that the view field is not affected; meanwhile, the device pulls the tumor through the tumor supporting device, and the effect of continuously manufacturing adjustable tension is achieved; and in addition, by arranging the annular collecting bin and the separating device, real-time collection of target excision tissue can be achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to an en-block resection device for bladder tumors based on resectoscope. Background technique [0002] The incidence of bladder tumors is high, and 75% of new bladder cancers are non-muscle invasive bladder cancer (NMIBC). For NMIBC, transurethral resection of bladder tumor (plasma) is the most commonly used treatment modality. Urethral bladder tumor (plasma) resection directly determines the curative effect of NMIBC treatment and the prognosis of patients. At present, in clinical NMIBC electrosurgical surgery, piecemeal resection is often used, but piecemeal resection is likely to cause tumor residues, and electrocautery of tumor tissue leads to eschar formation that is difficult to identify, and destroys the integrity of the tissue structure, and the tissue is chopped up and sent for biopsy It is easy to lead to pathological misdiagnosis and staging ...

AI Technical Summary

Problems solved by technology

However, the use of laser requires additional purchase of laser equipment and related consumables, which increases the cost; subcutaneous water injection is required in advance during the operation, which complicates the surgical procedure and increases the operation time; and it is difficult to deal with multiple (> 5) tumors, especially creeping growth tumors

However, en-block resection of bladder tumors using traditional resectoscope can eliminate the need to purchase new equipment and increase intraoperative consumables, and can treat multiple and pleomorphic tumors by combining en-block resection and traditional segmental resection. However, When traditional resectoscope is used for en-block resection of bladder tumors, it is difficult to obtain the appropriate tension for the tumor to achieve precise layer separation, and it is difficult to maintain the appropriate filling degree of the bladder for a long time to avoid frequently releasing water or adjusting the amount of water to affect the field of view, and it is difficult to detect the target lesion tissue. Precise cutting and accurate collection in real time to avoid the 3 main problems of target cut tissue mixed into other cut tissue fragments
