Abstract

The invention relates to a device for adjusting the curvature of a laparoscopic gastric volume adjustment band, which comprises a handle, an angle wheel and a flexible tube. There is a rotating shaft on the handle, one end of the rotating shaft extends into the handle, and the end of the rotating shaft inside the handle is provided with a pulley, and the pulley can rotate together with the rotating shaft, and the angle wheel is arranged at the end of the rotating shaft outside the handle; one end of the hose extends into the In the handle, the other end is provided with a terminal part, and a steel wire is provided in the hose, both ends of the steel wire are fixed on the terminal part, and the middle part of the steel wire extends into the handle and is wound around the On the pulley; the rotation angle wheel can drive the pulley to rotate through the rotating shaft. When the pulley rotates, it pulls the steel wire and controls the bending direction of the hose. The invention pulls the steel wire installed in the hose by rotating the angle wheel, so as to achieve the purpose of bending the hose; it saves the visual related parts incidentally when using the fiber endoscope, and has a simple structure, low cost, and is convenient to carry and move , very suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the technical field of clinical medicine, in particular to an endoscopic gastric volume adjustment belt curvature adjustment device. Background technique [0002] During gastric volume change surgery (such as: gastric cuff surgery), a gastric volume adjustment band needs to be inserted into the stomach through the patient's mouth to support the remnant stomach and give the operator a volume reference. Due to the relatively hard material of the gastric volume regulating band, once the gastric volume regulating band is inserted into the patient's stomach, it is inconvenient to change the angle of the gastric volume regulating band, and for this reason, it is very difficult to enter the duodenum. In the prior art, fiberoptic endoscopy is mainly used to observe the inner contour and shape of the gastrointestinal tract, trachea, and bronchus more comprehensively, and to improve the detection rate of related lesions. However, the di...
