Embodiment 1

[0054] figure 1 Shown is a bladder tumor cutter in a preferred embodiment of the present invention, which includes a handle 100, a mirror sheath connector 200, a connecting tube 300, a storage bag 400 and a wire 500 (see image 3 ). Wherein, the handle 100 is connected to the rear end of the connecting tube 300 as a manipulation site for entraining and resecting the bladder tumor. The mirror sheath connector 200 is sleeved on the connecting tube 300. When in use, the connecting tube 300 extends into the mirror sheath 600. The mirror sheath connector 200 is used to connect with the mirror sheath 600. The mirror sheath 600 can be a conventional cystoscope sheath. It can be connected with the mirror sheath connecting head 200 in an existing common way. The storage bag 400 is connected to the front end of the connecting pipe 300 . The metal wire 500 is folded into double wires and threaded in the connecting pipe 300 along the axial direction.

[0055] like figure 2 and 3 As...

Embodiment 2

[0068] The difference between Embodiment 2 and Embodiment 1 lies in the setting of the storage bag 400, such as Image 6 As shown, the opening of the storage bag 400 and the connecting pipe 300 form an angle of 0° (that is, the opening of the bag is parallel to the connecting pipe. Of course, the metal wire can be bent to make the opening of the bag upward or downward according to actual needs), and the front end of the connecting pipe 300 Stretch in from the side wall of the storage bag 400 seamlessly, the front end of the wire 111 passes through the side wall above the front end of the connecting pipe 300, and the end of the connecting pipe 300 located in the storage bag 400 is provided with a drainage hole 302; tighten the wire 500 When the opening of the storage bag 400 is tightened, the front end of the connecting pipe 300 can be wrapped. In this embodiment, the water in the storage bag 400 can enter through the outlet 302 at the front end of the connecting tube 300 and t...

Embodiment 3

[0070] The difference between Embodiment 3 and Embodiment 1 lies in the setting of the pulling member, including the setting of the slider 102 and the guide groove 103. The guide groove 103 is located on the side wall of the handle body 112 outside the first cavity 109, and the bottom of the guide groove 103 is located at the A protrusion is formed in a cavity 109 , and the through hole through which the connecting column 105 passes is located at the front end of the protrusion. The slider 102 is slidably fitted in the guide groove 103 by clipping.

Abstract

The invention discloses a bladder tumor cutter. The bladder tumor cutter comprises a connecting tube, a metal wire and a handle, wherein the wire is arranged inside the connecting tube in a penetrating mode; the handle is connected to the rear end of the connecting tube; the front end of the connecting tube is connected with a collecting bag; the front end of the metal wire is connected onto the circumference of the opening of the collecting bag, and a part of the metal wire, which is positioned on the front edge of the opening of the collecting bag, is exposed to serve as an electric cutting wire; the handle comprises a columnar handle body, which is provided with a traction member, and the traction member is provided with a power line; the two ends at the rear end of the metal wire penetrate out of the handle body via the side walls of the handle body and are connected with the power line. The bladder tumor cutter can integrally cut off and collecting tumors in different positions and sizes in bladder through the metal wire and the collecting bag, thereby effectively reducing amount of bleeding during surgery, avoiding tumor floating, ensuring a clear operative view field, shortening the surgical time and greatly lowering the difficulty in tumor excision as well as the risks of tumor recurrence.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a bladder tumor cutter. Background technique [0002] Bladder tumor is a relatively common urological tumor at present. Its incidence and recurrence rate are increasing year by year, and the age of onset is also showing a younger trend, which obviously affects the quality of life and prognosis of patients. Treatment options for bladder tumors include TURBT, partial cystectomy, and total cystectomy. In most TURBT operations, the surgeon will face the situation of large tumor volume and wide base, etc., requiring the surgeon to resect the tumor multiple times and in pieces with a traditional resectoscope. However, during the resection process, the tumor is rich in Vascular tissue will cause a large area of ​​bleeding, which will obviously affect the operator's field of vision. In addition, the scattered tumor tissue floating in the bladder also aggravates the ...
