Medical endoscope chip and system
Technical field
The invention relates to a kind of medical endoscope.
Background technology
Medical endoscope generally comprises access section, observation section and operating portion, and access section can stretch into inside of human body, and it has front-end and back-end, and observation section is located at the front end of this access section, and operating portion rear end and operating portion are fixed as one.Observation section comprises camera lens, imageing sensor and wiring board, and operating portion can move at different directions and position in controlled observation portion, realizes human body detected part multi-orientation detection.But existing endoscope has following shortcoming: 1) diameter of wiring board is comparatively large, thus causes whole observation section size larger.2) camera lens is fixing in the circuit board by the frame independently arranged in its surrounding, causes the diameter of whole observation section larger.
Summary of the invention
The invention provides a kind of medical endoscope that can effectively reduce size.
The invention provides a kind of endoscope, comprise access section, observation section and operating portion, described access section has front-end and back-end, described observation section is located at described front end, described observation section comprises camera lens and system line plate, described camera lens has integral type temple, described system line plate comprises multiple stacked and wiring board unit be fixed as one, each described wiring board unit all has functional module, the rear end of described access section is provided with adapter, described access section is removably connected by described adapter and described operating portion, and described temple coordinates with the grafting of described system line plate.Adapter can realize machinery, electrical connection.
The described wiring board unit being positioned at the superiors has image sensor module, and described image sensor module is positioned at immediately below described camera lens, and described temple coordinates with the described wiring board unit grafting being positioned at the superiors.
It is one or more that described functional module is selected from ASIC module, memory module, power module, interface module and lighting module.
Described wiring board unit is connected by flexible circuit board.
Each described wiring board unit is all cylindrical.
Each described wiring board unit is welded and fixed one.
A kind of access section assembly of medical endoscope, comprise access section and observation section, described access section has front-end and back-end, described observation section is located at described front end, and described observation section comprises camera lens and system line plate, and described camera lens has integral type temple, described system line plate comprises multiple stacked and wiring board unit be fixed as one, each described wiring board unit all has functional module, and the rear end of described access section is provided with adapter, and described temple coordinates with the grafting of described system line plate.Adapter can realize electrically, be mechanically connected with the operating portion of medical endoscope.Functional module is as ASIC module, memory module, power module, interface module or lighting module etc.
Each described wiring board unit is connected by flexible circuit board and is welded and fixed one.
The invention has the beneficial effects as follows: existing line plate is decomposed into multiple wiring board unit and stacked fixing, effectively reduce the diameter of wiring board, reduce the diameter in endoscopic observation portion, and then reduce the size of endoscope; Camera lens is integrally formed temple, and temple directly coordinates with wiring board grafting, also reduces the size of endoscope.

Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by detailed description of the invention.
As shown in Figure 1 to Figure 3, present embodiment medical endoscope comprises access section 1, observation section 2 and operating portion 3.Access section 1 can stretch into inside of human body, and it has front end 11 and rear end 12.Observation section 2 can obtain the image at position to be detected, and it comprises camera lens 21 and system line plate 23, and camera lens has the temple 211 integrally processed or mold, the jack 232 on temple 211 insertion system wiring board, and the grafting realizing camera lens 21 and wiring board 23 coordinates.The rear end of access section has adapter 13, and access section 1 is coordinated with operating portion 3 grafting by this adapter 13, and medical personnel, by operation operating portion, can regulate direction and the position of observation unit.
Camera lens 21 by mould molding or cutting or can grind one or more temple 211.When designed lines plate, according to various functional requirement, multiple wiring board unit 231 with functional module can be designed, between each wiring board unit, adopt as far as possible few line; Then, each wiring board unit is processed into circle; Finally, each wiring board unit 231 is stacked, and each wiring board unit is welded and fixed one.Functional module is as image sensor module, memory module, power module, ASIC module or interface module etc.
During use, endoscope's access section being stretched into inside of human body, by adjusting the direction of observation section and position (function of this adjustment, principle are with existing endoscope), obtaining multiple images of detected part.After finishing using, access section 1 and operating portion 3 are departed from, and access section 1 entirety with observation section 2 is abandoned, achieve the single use of access section, use safe and sanitary, compared to price and the high maintenance cost of existing endoscope costliness, effectively reduce cost.
For endoscope, system line plate 23 can have multiple wiring board unit 231, and each wiring board unit 231 is had respective function and connected by flexible circuit board 233.When the temple of camera lens coordinates with wiring board, only jack 232 can be set at the wiring board unit of the superiors.The wiring board unit being positioned at the superiors has image sensor module 22, and image sensor module 22 is positioned at the below of camera lens 21.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made.
