Description

Technical Field

[0001] The utility model belongs to the field of endoscopes, and in particular relates to a photoelectric composite cable for an endoscope. Background Art

[0002] An endoscope is a kind of detection instrument. Medical endoscopes can enter the human body through the natural cavity and transmit the images inside the human body to facilitate doctors to observe and treat. The front end of the endoscope is equipped with a lighting body to match the camera. The lighting body commonly used in the industry is LED lamp, but the heat generated by LED when working normally is very high and it is easy to cause harm to the human body. Utility Model Content

[0003] The utility model aims to provide a photoelectric composite cable for an endoscope.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An optoelectronic composite cable for an endoscope comprises a plurality of coaxial line components for transmitting signals and optical fibers for transmitting light. A shielding layer is arranged on the outside of the coaxial line components, a protective tape is arranged on the outside of the shielding layer, and the optical fiber is wrapped around the outside of the protective tape.

[0006] Preferably, the coaxial line assembly comprises a plurality of groups of coaxial line cores twisted with each other, the outer side of the core is wrapped with an insulating layer, and the outer side of the insulating layer is wrapped with a layer of transversely wound wire.

[0007] Preferably, the protective tape is arranged between the optical fiber and the transverse winding wire.

[0008] Preferably, a receiving space is formed between the plurality of groups of the coaxial line components and the shielding layer, and a ground wire is arranged in the receiving space.

[0009] Preferably, an outer sheath is provided on the outer side of the optical fiber.

[0010] Preferably, several groups of the coaxial line components, the shielding layer, the protective tape, and the ground wire are wrapped as a whole by the outer sheath.

[0011] The beneficial effect of the utility model is that traditional LED lamps will generate very high heat when working normally, which will affect patients. Optical fiber is used instead of traditional LED lamps for lighting. This transmission method will not produce resistance and magnetic loss, so the heat generated when transmitting light is extremely small and will not affect patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 The utility model is a cross-sectional structural schematic diagram.

[0013] Among them: a coaxial line core 10 , an insulating layer 12 , a transverse coiled wire 14 , a ground wire 16 , a shielding layer 18 , a protective tape 20 , an optical fiber 22 , and an outer sheath 24 . DETAILED DESCRIPTION

[0014] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0015] like Figure 1 As shown, the utility model is an optoelectronic composite cable for endoscope, comprising a plurality of coaxial line components for transmitting signals and optical fibers 22 for transmitting light, a circle of shielding layer 18 is arranged on the outside of the coaxial line components, a circle of protective tape 20 is arranged on the outside of the shielding layer 18, and the optical fiber 22 is surrounded on the outside of the protective tape 20;

[0016] The coaxial line assembly is used to transmit signals, and the optical fiber 22 is used to transmit light, replacing the traditional LED lamp, reducing the temperature rise of the lamp beads during the working lighting of the traditional LED lamp, and reducing the impact on the patient

[0017] The coaxial line assembly includes a plurality of groups of coaxial line cores 10 twisted together, the outer side of the core is wrapped with an insulating layer 12, and the outer side of the insulating layer 12 is wrapped with a layer of transverse coiled wire 14;

[0018] Multiple coaxial line cores 10 are twisted together, and the radio waves radiated by each coaxial line core 10 during transmission will cancel each other out with the radio waves emitted by other coaxial line cores 10, effectively reducing the degree of signal interference. The transverse coiled wire 14 plays a shielding role to prevent mutual interference between multiple signal transmission components.

[0019] The protective tape 20 is disposed between the optical fiber 22 and the transverse winding wire 14;

[0020] The protective tape 20 can protect the optical fiber 22 .

[0021] An accommodation space is formed between the plurality of coaxial line components and the shielding layer 18, and a ground wire 16 is arranged in the accommodation space;

[0022] The ground wire 16 can effectively prevent electric shock caused by malfunction of the endoscope, thereby ensuring the health and safety of the patient.

[0023] An outer sheath 24 is provided on the outside of the optical fiber 22, and a plurality of groups of coaxial line components, a shielding layer 18, a protective tape 20, and a ground wire 16 are wrapped together by the outer sheath 24;

[0024] The outer sheath 24 can tightly bundle the internal materials such as the coaxial line assembly and the optical fiber 22 into one, and protect the internal materials.
