Because insertion section 1 is to need the part into human body, structure is relatively compact, has multiple passages in it in addition, Also need to arrange the wire of consuming parts and signal component simultaneously, multiple passages opened up in small parts and there is processed complex, After the wire of two parts is gathered together by this programme, it can only need to set a cable passage, letter in insertion section 1 The problem of inner structure of insertion section 1 is complicated is changed.

As depicted in figs. 1 and 2, an operating portion 3 is installed with neighbouring duct portion 2 and the duct portion 2 of the junction of insertion section 1, Operating portion 3 is provided with terminative connector/male end company with Male end connector/terminative connector pairing adjacent to the end of insertion section 1 Connect device.The Male end connector that the end of insertion section 1 is set/terminative connector electrical connection and terminative connector/public affairs on operating portion 3 Terminal adapter matches to form wire and cable connector 4.

During implementation, this programme preferred operations portion 3 surface offers a duct portion 2 for being used to place disposable portion Neck；Relay process unit 31 is positioned in the cavity opened up inside operating portion 3.

The setting of neck, when being checked using endoscopic system patient, by the neck of operating portion 3 with disposably making It is engaged with portion, rapidly disposable portion can be installed together with operating portion 3, after having checked, one can be facilitated Secondary property uses the replacing in portion.

The surface of operating portion 3 is provided with the suction shaft for being easy to operation and aqueous vapor switching switch, suction shaft and aqueous vapor switching Switch constitutes controlling switch 32.Operating portion 3 be internally provided with respectively with terminative connector/Male end connector, suction shaft, aqueous vapor The relay process unit 31 that switching switch and control unit 5 are connected；Control unit 5 connects with suction device 6 and aqueous vapor device 7 respectively Connect.

Because suction shaft and aqueous vapor switching switch are arranged on the operating portion 3 of doctor's hand gripping, doctor can be facilitated to exist Operation switching when checking patient.

, will after suction shaft, aqueous vapor switching switch, control unit 5 and the several parts of relay process unit 31 be combined with each other Conventionally employed Mechanical course tracheae 23, water pipe 22 and suction tube 21, which are changed into signal control, disposable portion, to be set Multiple line branchings are put, disposable portion's internal structure is simplified, eliminates multiple line branchings, no longer worry that pipeline crosses The problem of place is leaked.

In one embodiment of the invention, aqueous vapor device 7 is provided with magnetic valve with water pipe 22 and the junction of tracheae 23, Suction device 6 is provided with a magnetic valve with the junction of suction tube 21；All magnetic valves are connected with pipeline control unit 5.

Wherein, suction shaft, aqueous vapor switching switch, control unit 5, relay process unit 31 and all magnetic valves are this The control section of system.

As shown in Fig. 2 being provided with the guiding wire and cable connector being mutually paired on the end face relative with insertion section 1 of operating portion 3 33, the guiding wire and cable connector 33 on operating portion 3 is connected by cable with the steering operation handle 34 on operating portion 3, insertion section 1 On guiding wire and cable connector 33 be connected by cable with the snake bone section 8 on insertion section 1.

During implementation, this programme preferred operations portion 3 is oriented to every cable fixed in wire and cable connector 33 and insertion section 1 It is oriented to cable corresponding in wire and cable connector 33 and is fixedly connected or is fixed by hook and link fit structure by magnet and connects Connect.

In one embodiment of the invention, LED 12 is less than or equal to the micro- of 2.3mm and illuminance uniformity using diameter Type LED, the beam lighting angle of LED 12 is more than the angle of visual field；The beam lighting angle of LED 12 at least above the angle of visual field, its Colour rendering index is higher than 90%.

Whether the illumination of LED 12 is uniform, directly influences the uniformity of brightness, LED 12 in the range of exposures of LED 12 and shines The quality of the uniformity of heat and the image of the collection of imaging lens 13 is produced in the range of penetrating, in order to ensure that imaging lens 13 are gathered Image definition and burning of being caused to patient skin of illumination temperature rise, the LED 12 of this programme uses following structure：

LED 12 includes luminescent layer 121 and is arranged on the cuboid lens 122 of luminescent layer 121；Or LED 12 includes lighting Layer 121, planar lens 123 and lower surface are the square body lens 124 of concave curved surface, and planar lens 123 is located at luminescent layer 121 Between square body lens 124.

By Fig. 5 and Fig. 6, by the reflection of light as can be seen that the light source that luminescent layer 121 is produced can be saturating by cuboid The projection of mirror 122 or square body lens 124 and planar lens 123 and the reflection of inner surface realize that uniformity is illuminated.

In one embodiment of the invention, control unit 5 include LED luminance control module and respectively with relay process list The pipeline control module and image processing module of the connection of member 31；Image processing module is connected by LED drive module with LED 12 Connect, pipeline control module is connected with suction device 6 and aqueous vapor device 7 respectively.

When the difference between the brightness for the image that imaging lens 13 are gathered and object brightness is more than given threshold, if difference More than zero, judge whether the current driving current of LED 12 reaches maximum current, if it is not, calculating brightness of image reaches that target is bright Target current needed for degree, if target current is more than maximum current, adjusts the driving current of LED 12 to maximum current, no Then, the driving current of adjustment LED 12 is to target current；

If difference is less than or equal to zero, judge whether the current driving current of LED 12 reaches minimum current, if it is not, calculating image Brightness reaches the target current needed for object brightness, if target current is more than or equal to minimum current, adjusts the driving of LED 12 Electric current is to minimum current, otherwise, adjusts the driving current of LED 12 to target current.

LED 12 is in illumination, and quick heating is set after LED luminance control module, it can be gathered according to imaging lens 13 Image the electric current of LED 12 is adjusted in setting range in real time, optimum range is located at the brightness for ensuring LED 12 While interior, the surface temperature control of LED 12 is set to be limited in safety（40℃）Under, usually 40 DEG C.

Duct portion 2 is located at size of the place of operating portion 3 in section Yu the junction of insertion section 1 and is connected thereto end less than insertion section 1 Size.

In summary, due to the setting in disposable portion, the part of all and direct body contact or mediate contact is made To be disposable, the cross-infection reused can be avoided.

Disposable portion and operating portion 3 are dismountable connected mode, facilitate the fast of disposable portion and operating portion 3 Fast assembly and disassembly, so set the reuse that can ensure not with the operating portion 3 of direct body contact.

Head end preposition miniature LED provide illumination, it is to avoid employs high power external light source and fibre bundle, greatly simplify and is The composition structure of system, and considerably reduce cost.

Aqueous vapor device 7 is controlled with electric signal by the suction shaft on operating portion 3 and aqueous vapor switching switch realization and attracted Device 6 realizes aqueous vapor switching and attracts switching, reduces pipeline structure, reduces the branch of pipeline, so as to reduce leakage wind Danger, improves the security used.
