Problems solved by technology

[0003] Among them, the key and cumbersome steps in the operation mainly lie in the technique of resecting the distal ureter. At present, the laparoscopic and endoluminal surgical instruments and the main matching surgical methods for this operation are very limited. Ureterectomy, transurethral segmental ureterectomy, and unsheathing method all have very complicated steps, and some of them need to be combined with urethral cystoscopy.

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0021] refer to Figures 1 to 2 As shown, a surgical device for urothelial carcinoma in this embodiment includes a hand-held tube 1 for extending into the ureter and an end of the hand-held tube 1 for clamping the inner wall of the bladder around the orifice at the end of the ureter. The card joint 2, the card joint 2 includes a connection seat 21 and a water bag 22 sleeved on the connection seat 21, the connection seat 21 is fixedly connected to the end of the hand-held tube 1, and the water bag 22 is connected to the hand-held tube 1 The interior of the water bladder 22 is connected to each other, and several barbs 23 are distributed on the outer surface of the water bladder 22. When the hand-held tube 1 is inserted into the ureter, the water bladder 22 is filled with water and expands, and the barbs 23 hook the inner wall of the bl...

Abstract

The invention discloses urothelium carcinoma surgical equipment which comprises a handheld pipe for being extended into a ureter, a clamping connection head arranged at one end of the handheld pipe and used for clamping the inner wall of the ureter and perfusion design convenient for chemotherapeutics, the clamping connection head comprises a connection seat and an airbag sleeving the connection seat, the connections seat is fixedly connected with the end of the handheld pipe, the airbag is communicated with the inside of the handheld pipe, and a plurality of overhead hooks are distributed onthe outer side face of the airbag. When the handheld pipe is extended into the ureter, the airbag is inflated to expand, and the overhead hooks hook the inner wall of the ureter.

Description

technical field [0001] The present invention relates to an operation device, more specifically relates to a urothelial cancer, including the operation device and method for ureter epithelial cancer which is common among them. Background technique [0002] Radical full-length nephrectomy and ureterectomy combined with local sleeve resection of vesicoureter is currently the gold standard for surgical treatment of ureteral cancer, regardless of the upper or lower location of the tumor. Due to the extremely easy dissemination, implantation, and recurrence of urothelial carcinoma, the principle of tumor-free must be strictly followed during the entire radical operation, and the urinary tract must not be cut during the operation to prevent the spread of tumor implantation. [0003] Among them, the key and cumbersome steps in the operation mainly lie in the technique of resecting the distal ureter. At present, the laparoscopic and endoluminal surgical instruments and the main match...
