Minimally invasive endoscope
2023/04/18
The structure of different models of mirrors is not entirely the same, but they all have the following basic structures: the tip, insertion part, operation part, eyepiece part, light guide hose part, and light guide plug part. Tip: The tip is composed of a curved part and a hard part. The bending part is located between the hard part at the tip and the insertion part, and is composed of many circular parts to form a snake tube. Each pair of adjacent circular parts can move up, down, left, and right. The bending angle determines the field of view direction of the endoscope objective, and the bending radius determines the flexibility of operation. The hard part at the tip is the inflexible part of the endoscope, which is the heart of the endoscope. The key component of the endoscope, the lens group, is located here. Due to the metal structure used in the hard part, the shorter the length, the better the operability of the endoscope inside the cavity. The hard part at the tip is equipped with a light guide window, objective lens, clamp outlet, nozzle, etc. According to the above description, our existing product size is controlled within the size of rice grains. While reducing the size, we still need to meet the size and accuracy requirements of functional holes, which poses a high challenge for micro machining. Moreover, due to the fact that the product belongs to the human body level, there are strict requirements for product accuracy and surface finish, and complete burrs must be achieved. To meet the requirements, we use high-precision CITIZEN machine tools and customize them Knives to ensure product reliability)
