Description

Technical Field

[0001] The invention belongs to the technical field of optical elements, and in particular relates to an endoscope manufacturing process and an endoscope manufactured therefrom. Background Art

[0002] An endoscope is a slender instrument used to observe, diagnose and treat internal human body lesions with the help of imaging and lighting systems. Existing endoscopes use intra-scope optical fiber bundles or intra-scope LED lighting. These two methods greatly occupy the precious space inside the scope, resulting in limited space for effective functional components inside the scope, making it difficult to integrate more functions into the endoscope.

[0003] In addition, the endoscope needs to be inserted into the patient's body for operation. The body fluids and drugs in the patient's body will penetrate through the gap between the endoscope substrate and the substrate coating, causing corrosion to the endoscope substrate. In some special inspections or treatments that require stringent endoscope performance, such as performing delicate operations in narrow and tortuous body cavities, the endoscope needs to better cope with complex mechanical environments. If the stress is too large or acts for a long time, the joint between the endoscope substrate and the substrate coating is prone to separation. In severe cases, the endoscope substrate will rupture, exposing the internal precision components, affecting the normal use of the endoscope, and causing harm to the patient. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an endoscope manufacturing process and an endoscope manufactured thereby, so as to solve the problem of space occupation by existing endoscope lighting methods, and at the same time improve the bonding between the endoscope and the coating layer, reduce the problems of separation of the bonding joint and rupture of the substrate due to stress, and improve the reliability and stability of the endoscope.

[0005] To solve the above problems, the technical solution adopted by the present invention is:

[0006] An endoscope manufacturing process comprises the following steps:

[0007] S1. Pretreatment of optical fiber:

[0008] First, titanium vapor is vapor-deposited on the outer surface of the optical fiber to form a sensitized metal layer with a thickness of 200-300 nm. Then, the optical fiber is placed in a gold plating solution to make the sensitized metal layer on the surface of the optical fiber fully contact with the gold plating solution. The gold ions in the gold plating solution are reduced to gold atoms and deposited on the surface of the sensitized metal layer to form a gold plating layer with a thickness of 50-500 nm.

[0009] S2. Oxide powder pretreatment:

[0010] Immersing the oxide powder in a soft magnetic metal ion plating solution, so that the oxide powder is fully in contact with the soft magnetic metal ion plating solution, the soft magnetic metal ions in the soft magnetic metal ion plating solution are reduced to soft magnetic metal atoms and deposited on the surface of the oxide powder to form a soft magnetic metal coating, the thickness of the soft magnetic metal coating is 10-50nm;

[0011] S3. Constructing optical signal pathway and electrical pathway:

[0012] A controllable magnetic field region is constructed by using a permanent magnet array, and a mirror body substrate is placed in the magnetic field. The mirror body substrate is used as an electrode. In an electrolyte containing transition metal ions and oxide powders, the current is controlled to deposit the transition metal ions and oxide powders on the outer surface of the mirror body substrate to form a stainless steel metal layer containing oxide powders. The thickness of the stainless steel metal layer is 110-200 μm. The oxide powders in the stainless steel metal layer are arranged in a chain-like manner perpendicular to the mirror body substrate in the magnetic field. The stainless steel metal layer is treated with an acid solution, and the acid solution reacts chemically with the oxide powders to form open blind holes in the stainless steel metal layer. The diameter-to-depth ratio of the open blind holes is ≥2. The blind hole is vacuum dried and exhausted, and then the pretreated optical fiber is axially arranged on the outer surface of the stainless steel metal layer. Then, a connecting agent is injected into the open blind hole, and vacuum dried and degassed. Finally, resin filling is performed to allow the resin to enter the open blind hole and combine with the connecting agent. Ultrasonic diffusion treatment is used to further diffuse the filled resin. The resin forms a resin anchor body inside the open blind hole, and a resin layer is formed on the surface of the stainless steel metal layer. The optical fiber is wrapped inside the resin layer. The optical fiber forms an optical signal path, and the stainless steel metal layer forms an electrical path. The mirror body substrate, the optical fiber, the stainless steel metal layer, the open blind hole, the resin anchor body and the resin layer together constitute the mirror body.

[0013] S4. Constructing Indium Tin Oxide Conductive Strip:

[0014] Spray-depositing indium tin oxide onto the outer surface of the lens to form an indium tin oxide conductive strip;

[0015] S5. Sealing of lens and lens body:

[0016] Titanium vapor, zirconium vapor or nickel vapor is vapor-deposited on the circumferential end face of the lens to form a metal connecting layer, and the metal connecting layer is respectively connected to the two ends of the indium tin oxide conductive tape. The inner surface of the lens body is gold-plated to form a gold-plated connecting layer. The gap between the metal connecting layer and the gold-plated connecting layer is maintained between 5 and 200 μm. A potassium gold cyanide solution is used as a circulating medium to flow in the gap between the metal connecting layer and the gold-plated connecting layer. At the same time, the metal connecting layer and the gold-plated connecting layer are irradiated with a laser. The potassium gold cyanide in the potassium gold cyanide solution decomposes to produce gold, which is deposited between the metal connecting layer and the gold-plated connecting layer to form a connection.

[0017] Furthermore, the diameter of the optical fiber is 10-100 μm.

[0018] Furthermore, the oxide powder is calcium oxide powder or sodium oxide powder, and the oxide powder as a whole is a flaky powder with an aspect ratio greater than 1.

[0019] Furthermore, the soft magnetic metal is iron metal or cobalt metal.

[0020] Furthermore, the linking agent is siloxane having a hydroxyl group, and the siloxane having a hydroxyl group is hydroxypolydimethylsiloxane.

[0021] Furthermore, the acid solution is hydrofluoric acid, sulfuric acid, nitric acid or hydrochloric acid.

[0022] Furthermore, the transition metal ions are iron ions, nickel ions and chromium ions, the mass ratio of iron ions in the transition metal ions is 70-72%, the mass ratio of nickel ions is 15-18%, and the rest are chromium ions, and the resin is epoxy resin.

[0023] Furthermore, the gap between the metal connection layer and the gold-plated connection layer is between 50 and 100 μm.

[0024] An endoscope manufactured by an endoscope manufacturing process comprises an endoscope body, wherein lenses and operating handles are respectively arranged at both ends of the endoscope body, a light source module and a power supply are arranged inside the operating handle, the endoscope body comprises a endoscope body substrate, a light guide fiber and a stainless steel metal layer are arranged outside the endoscope body substrate, an open blind hole is arranged in the stainless steel metal layer, the open blind hole is filled with resin, a resin anchor body is formed inside the open blind hole, a resin layer is formed on the surface of the stainless steel metal layer, the light guide fiber is wrapped inside the resin layer, the endoscope body substrate, the light guide fiber, the stainless steel metal layer, the open blind hole, the resin anchor body and the resin layer together constitute the endoscope body, the end of the light guide fiber away from the lens is connected to the light source module, and the end of the stainless steel metal layer away from the lens is connected to the power supply.

[0025] Furthermore, the scope body is provided with an isolation protection structure in conjunction with the operating handle, and the isolation protection structure includes an isolation cover and a tightening sleeve. The isolation cover is generally arranged in a hollow frustum shape, with the large-diameter end of the isolation cover arranged away from the scope body, and the small-diameter end of the isolation cover is fixed on the scope body in conjunction with the tightening sleeve.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] By constructing a resin anchor body and a resin layer, the light-guiding fiber, the stainless steel metal layer and the endoscope body are tightly integrated together, thereby preventing the light-guiding fiber from occupying too much space in the endoscope body, facilitating functional integration, and preventing gaps, separations or even ruptures between the endoscope body base and the stainless steel metal layer when the endoscope performs delicate operations in narrow and tortuous body cavities.

[0028] The resin anchor body and the resin layer are made of epoxy resin, the material of the light-guiding fiber is polymethyl methacrylate, and the connecting agent used is siloxane with hydroxyl groups. Due to the hydrogen bonding effect of hydroxyl groups, siloxane bonds, epoxy groups, and ester groups, they are attracted to each other. Since the surface of the stainless steel metal layer is acidic, it is attracted to the hydroxyl groups to form a stable whole. Therefore, the resin anchor body, the resin layer, the light-guiding fiber, the stainless steel metal layer and the mirror body substrate are firmly connected.

[0029] By arranging a metal connecting layer on the circumferential end face of the lens and a gold-plated connecting layer on the inner surface of the lens body, the sealing method of the lens and the lens body is optimized. When the metal connecting layer and the gold-plated connecting layer are irradiated with a laser, the high energy of the laser will break the gold-cyanide bond of potassium gold cyanide, and the gold ions will obtain electrons and be reduced to gold atoms. These gold atoms are deposited between the metal connecting layer and the gold-plated connecting layer to form an atomic-level connection of gold, thereby enhancing the strength and stability of the connection. The potassium gold cyanide solution flows in the gap as a circulating medium, which can ensure that the gold atoms are evenly deposited in the entire gap. This connection method not only solves the problem that the adhesive material used in the adhesive connection is easy to deteriorate and cause the lens packaging failure, but also solves the problem that the welding material used in the welding connection is hard and brittle, causing the lens to be subjected to greater stress. The lens can withstand more demanding application environments.

[0030] By depositing indium tin oxide conductive tape on the lens, the lens can be heated and defogged using electric current, ensuring the imaging clarity of the endoscope during use. It is suitable for operating environments with high humidity or low temperature.

[0031] The present invention solves the problem of space occupation by existing endoscope lighting methods, while improving the bonding between the endoscope body substrate and the stainless steel metal layer, enhancing the endoscope's ability to cope with complex mechanical environments, reducing failures caused by stress during inspection or treatment, and improving the reliability and stability of the endoscope.
