Problems solved by technology

[0003] For intracavitary lesions that are large in size, irregular in shape, multiple, or located in the blind area of ​​the operation, the current medical devices still have certain limitations in the operation, and often require multiple operations to resect, which is easy to lose the anatomical level and is not convenient for surgical operation , and it is easy to cause incomplete resection or too deep or too much tissue resection, which will lead to unsatisfactory surgical results, high postoperative complications and recurrence rates, etc.

Abstract

The invention relates to a bendable surgical instrument with a pre-bending pipe structure. The bendable surgical instrument is provided with a handle and an operating rod. A pre-bending pipes is disposed in the handle and the operating rod and assembled to the push-pull rod of a push-pull handle. The operating rod can move relative to the handle to adjust the extending length of the pre-bending pipe relative to the operating rod. The operating rod is communicated with the interior of the pre-bending pipe to form a built-in instrument channel. One or multiple embedded pre-bending pipes can be used. The bendable surgical instrument has the advantages that natural one-way bendable materials such as metal braided pipes are applied to the field of surgical instruments, the length of the metal braided pipes extending out of the far end of the operating rod is controlled through the push-pull handle, instrument tail ends of different shapes such as arc shapes and 'S' double-curvature bending shapes, the surgical instrument assembled into the built-in instrument channel can reach all parts of lesions, operation fineness is achieved, all angles are achieved, blind areas are avoided, and tumors of various forms and at various positions can be cut off conveniently, and the bendable surgical instrument is simple to operate and good in surgical effect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bendable surgical instrument with a pre-bent tube structure. Background technique [0002] At present, endovascular surgery is an important method for the treatment of non-muscle invasive bladder tumors and other diseases. With the continuous development of science and technology, endovascular surgery treatment methods are emerging in an endless stream, including monopolar resection, plasma resection, holmium laser, thulium laser Surgery, fluorescein or NBI-assisted resection, etc. [0003] For intracavitary lesions that are large in size, irregular in shape, multiple, or located in the blind area of ​​the operation, the current medical devices still have certain limitations in the operation, and often require multiple operations to resect, which is easy to lose the anatomical level and is not convenient for surgical operation , and it is easy to cause incomplete r...
