Problems solved by technology

This kind of optical system not only has high manufacturing cost of optical components, but also requires high technology for assembly. Therefore, the manufacturers capable of manufacturing endoscopes are limited and the manufacturing cost is very high. Therefore, the price of endoscopes is very high, and hospitals have to do so. It is the current reality that endoscopes are not reused

Embodiment 1

[0027] Example 1: Endoscope Optical System

[0028] see figure 2 The shown endoscopic optical system comprises a plastic optical fiber 1 and an integral lens 2 formed by resin injection molding, the left end of the plastic optical fiber is coaxial with the lens and extends into the rear end of the lens to form an integral body and extends into the lens The end face 11 of the left end of the inner plastic optical fiber is perpendicular to the optical axis of the lens.

[0029] The resins shown can be polyalkylsilicone resins (such as polymethylsilicone, polyethylsilicone), polyarylsilicone resins, or polyalkylarylsilicone resins (such as polymethylphenylsilicone resin, polyethylphenyl silicone resin). Plastic optical fiber (POF) is made of highly transparent polymers such as polystyrene (PS), polymethyl methacrylate (PMMA) or polycarbonate (PC) as the core material, and PMMA or fluoroplastic as the skin material. Class optical fiber (optical fiber), belongs to the prior art...

Embodiment 2

[0031] Embodiment 2: the preparation device of endoscope optical system

[0032] see Figure 4 In the preparation device of the endoscope optical system shown, the plastic optical fiber 1 beyond the end face of the flange is fixed on the flange 3; the lens mold 5 is connected with the end face 31 of the flange, and the end face of the flange is used to inject resin into the lens mold 5 to form a lens The mold cavity 51 is closed, and the plastic optical fiber 1 coaxial with the mold cavity extends into the rear end of the mold cavity, and two gates 52 for resin injection are opened on the wall of the mold cavity radially opposite to the plastic optical fiber inserted into the mold cavity. . The two gates are symmetrical to the axis of the plastic optical fiber.

Embodiment 3

[0033] Embodiment 3: the preparation method of endoscope optical system

[0034] The preparation device described in Example 2 was used. First fix the plastic optical fiber 1 on the center of the flange 3, see Figure 5 , the plastic optical fiber beyond the end face of the flange extends into the hole 61 opened on the fixing plate 6 that is equal to the outer diameter of the plastic optical fiber, and the fixing plate 6 is contacted and fixed with the end face 31 of the flange, and then the end face of the fixing plate is milled with a milling machine. 62 for milling, of course, the end face of the plastic optical fiber is also milled, see Figure 6 , and then remove the fixing plate. Then the flange 3 fixed with the plastic optical fiber 1 is fixedly connected with the lens mold 5, see Figure 7 , the flange end face 31 closes the mold cavity 51, and the plastic optical fiber 1 extends into the rear end of the mold cavity 51. After the silicone resin is injected into the...

Abstract

The invention provides an endoscope optical system comprising a plastic optical fiber and an entire lens formed by resin molding. One end of the plastic fiber is coaxial to the lens and extends into the rear end of the lens integrally, and the end surface of the plastic optical fiber extending into the lens is perpendicular to the optical axis of the lens. The invention further provides a manufacture device of the endoscope optical system; a flange is fixed to the plastic optical fiber out of the end surface of the flange; a lens die is connected to the end surface of the flange, the end surface of the flange seals the die cavity, used for forming the lens by resin molding, of the lens die, the plastic optical fiber coaxial to the die cavity extends into the rear end of the die cavity, and the wall of the die cavity corresponding to the plastic optical fiber extending into the die cavity radially is provided with an injection port for resin injection. A manufacture method of the endoscope optical system includes using the manufacture device, and connecting the lens die to the end surface of the flange with the fixed plastic optical fiber; after injecting the resin into the die cavity through the injection port, cooling and forming, and removing the flange and the lens die.

Description

technical field [0001] The invention relates to an endoscope optical system, especially an inexpensive endoscope optical system and a manufacturing device and method thereof. Background technique [0002] Endoscopes are an indispensable tool for early diagnosis and treatment of diseases. From the current situation, endoscopes themselves are expensive, so they are repeatedly used in various ways such as disinfection. In order to avoid 100% infection prevention, meticulous cleaning and disinfection have also become an indispensable part, and medical equipment such as endoscope cleaning equipment must be equipped for this. In the medical field, although sterilization and disinfection work is carried out through appropriate procedures, it is currently impossible to perform complete sterilization. [0003] Therefore, cases of infection caused by blood, saliva, contents extracted from digestive organs, adhesion of tissues, etc. due to insufficient disinfection of endoscope proces...
