Description

Technical Field

[0001] The utility model relates to the technical field of urological surgical medical instruments, in particular to an endoscopic bladder specimen removal device. Background Art

[0002] In the field of urology, endoscopic examination and treatment are common clinical procedures, especially in the diagnosis and treatment of bladder diseases such as bladder tumors, cystitis, and bladder stones. Endoscopic vesical specimen removal is an important means of evaluating and treating these diseases. However, existing vesical specimen removal devices have some shortcomings, which affect the accuracy and safety of the surgery. The existing technology has the following disadvantages: poor stability during manual operation. During operation, traditional devices lack effective support and positioning structures, resulting in poor stability during intrabladder operation and prone to shaking, which affects the accurate removal of the specimen. The operation is complex. Some devices are complex in design and have cumbersome operation steps, which increases the operation time and requires high skills of the surgeon. In emergency situations, it may affect the efficiency of the operation and pose potential harm to the patient. The instrument design directly contacts the inner wall of the bladder, which may cause damage to the bladder wall during operation, increasing patient discomfort and postoperative recovery time. The integrity of the specimen is not guaranteed. During the specimen removal process, due to the limitations of the instrument design, the specimen is easily damaged or partially left in the bladder, affecting the subsequent pathological diagnosis.

[0003] Chinese patent publication number CN221105889U discloses an endoscopic bladder specimen removal device, which relates to the field of endoscope technology, including a hollow tube, which movably passes through an endoscope channel; a push rod, which is movably sleeved in the hollow tube; an operating head, which is installed at one end of the hollow tube and is connected to the push rod; a receiving mechanism, which is connected to the other end of the push rod and is movably engaged with the hollow tube, so that the hollow tube can be completely extended into the patient's body through the endoscope channel. When extended, the receiving mechanism is completely received in the hollow tube. The operating head pushes the push rod to extend and open the receiving mechanism, and the specimen is received under the guidance of the cystoscope. The receiving mechanism is then closed again by the operating head. If the specimen can enter the endoscope channel of the scope sheath, the specimen is removed from the endoscope channel. If the specimen is too large to enter the endoscope channel, the specimen is removed together with the endoscope after the receiving mechanism is closed.

[0004] However, the utility model has the following problems when it is actually used:

[0005] The utility model cannot achieve uniform movement when the entire device is used, and may cause harm to the patient by directly contacting the inside of the bladder. It cannot find the best point of force application, which reduces the accuracy during operation and does not provide a more comfortable operating experience and control. Utility Model Content
