Below the specific embodiment, with reference to the accompanying drawings, embodiments of the invention are described.

Fig. 1 is the structural representation of existing endoscopic apparatus, comprises probe 1, insertion tube 2 and main frame 3.Insertion tube 2 can be hard tube or soft pipe, and the inside is with optical fiber tube or holding wire (omitting in Fig. 1), and insertion tube 2 ends are probe 1, and popping one's head in 1 is generally columned.1 the inside of popping one's head in is provided with optical lens or electronics camera lens, to pop one's head in and 1 insert the chamber shape pipeline organ of human body as trachea, esophagus, anus etc. by insertion tube 2 during use, main frame 3 is with optical observation mirror or electronic display with probe 1 cooperating, and by popping one's head in, 1 pair of human internal organs is observed.

Spy upon an interior endoscope device system of using in of the present invention and comprise equally probe 1, insertion tube 2 and main frame 3.But be provided with a plurality of medium injection devices 4 on its main frame 3, be provided with the media lines 5 of many hollows in insertion tube 2 the insides, each media lines 5 is connected to medium injection device 4 separately.The rear end of medium injection device 4, be connected with the media Containers 6 for the store fluid medium.(while as fluid media (medium), adopting air, also can not need media Containers 6, essence that is to say using the interior space as media Containers).As Fig. 2.

Medium injection device 4 can adopt manual mechanical pump, or electronic electrodynamic pump.The simplest, form medium injection device 4 and media Containers 6 by a sacculus with elastic sealing exactly, the sacculus the inside is filled with gas or liquid medium, can play the effect of medium injection device 4 and media Containers 6 simultaneously, when the pressed by external force sacculus, sacculus is squeezed and plays the effect of pump, and medium is extruded to media lines, injects taper leather bag 12; When unclamping external force, sacculus restores to the original state because of elasticity, produces negative pressure and the Absorption of Medium of taper leather bag 12 the insides is returned.This mode is simply effective, and, without power, by the amount of sacculus pressurized deformation is set, can also control the amount of injected media, realizes quantitatively injecting.Certainly manual operations is cumbersome, so medium injection device 4 also can adopt electrodynamic pump, and be to change as required the flow direction of medium, be to adopt two-way pump, perhaps adopt two one-way pumps oppositely to form side by side, perhaps adopt one-way pump coordinate for change MEDIA FLOW to electromagnetic valve form, and controlled according to job demand by electronic circuit.These belong to the common prior art in fluid control field and electric automatization field.

Described fluid media (medium) can be gas, as nitrogen or air; Or liquid, as pure water or normal saline; According to the use location of endoscope, determine.Such as: be used in trachea, medium can adopt air, is used in anus, can adopt water.When purpose is that escape of liquid appears in contingency, can not damage human body.

Spy upon a structure of 1 in of the present invention as Fig. 3.At the outer surface of columniform probe front end, be provided with two or three or four s' the heavy hole 11 of spill around the probe diverse location of a week; Each spill is fixed with an airtight taper leather bag 12 that can inject fluid media (medium) on heavy hole 11, each taper leather bag 12 is with a cross over pipe 13, every cross over pipe 13 is connected to the media lines separately 5 of insertion tube 2 the insides separately, and every media lines 5 is connected on main frame medium injection device 4 separately separately.

Taper leather bag 12 adopts the thin flexible material with toughness and elastic, nonhazardous to make as silica gel or medical grade rubber, and its bottom is fixed on the heavy hole of spill with the heavy hole of the spill sticky note of 11 contacted parts.Taper leather bag 12 other places except following the UNICOM of cross over pipe 13 are airtight, when injecting fluid media (medium) as gas or liquid, taper leather bag 12 expands and heaves, the height of heaving can determine according to probe diameter and heavy hole size, and general suitable height is probe diameter 1/3rd arrives between half; When pumping medium, taper leather bag 12 shrinks and is adjacent on the heavy hole 11 of spill.Connection tube 13 enters probe 1 inside by the aperture that is arranged on 11 bottoms, the heavy hole of spill, and the diameter of aperture and cross over pipe 13 match, and cross over pipe enters the aperture place can do encapsulation process.(Fig. 3 does not mark aperture).Each root cross over pipe 13 that enters probe is connected with insertion tube 2 the insides media lines 5 separately, and media lines 5 is connected to main frame 3 the insides medium injection device 4 separately.

The quantity of taper leather bag 12 (being also the quantity in the heavy hole 11 of spill) is determined according to the requirement of angle adjustment.Adjusted angle if only need in one group of relative direction (up and down or left and right), can be on probe 1 outer surface, the position of the opposite end of one diameter of edge probe cross section arranges two taper leather bags 12, by contraction and the projection of adjusting two taper leather bags, thereby just can force probe to adjust viewing angle at this prescription to carrying out deflection, as Fig. 4.Carry out angle adjustment in two groups of relative directions (upper and lower and left and right) if need simultaneously, can be on above-mentioned unidirectional basis, according to two groups of mutually perpendicular modes of diameter, the position distributed on the probe outer surface, with four summits of positive rhombus arranges four taper leather bags, by contraction and the projection of adjusting four leather bags, can force probe at mutually perpendicular two prescriptions to the deflection of carrying out upper and lower and left and right, thereby realize the angle adjustment of four direction, as Fig. 5.The position of also can be on the probe outer surface, distributing with three summits of equilateral triangle arranges three taper leather bags, by the contraction of three taper leather bags of accurate adjustment and the degree of projection, also can realize the angle adjustment of four direction up and down, at this moment can save one group of taper leather bag and media lines and injection device, but the control accuracy that the medium of each taper leather bag is injected is had relatively high expectations.The heavy hole of more spill and taper leather bag can certainly be set, be conducive to improve the precision of angle adjustment, just structure and control can be more complicated.

Endoscopic apparatus of the present invention taper leather bag 12 is in the ordinary course of things pumped medium, shrinks and is fixed on the heavy hole 11 of each spill, during use, by will the pop one's head in chamber shape pipeline of 1 insertion human organ of insertion tube 2, is observed, and this point like the prior art.

When needs modulation viewing angle, can start certain or a plurality of medium injection device 4 of main frame, media lines 5 injection taper leather bags 12 by medium by insertion tube 2 the insides, expand this taper leather bag 12 and heave, and struts the organ mucosa covered above the taper leather bag.By handling different medium injection devices, can make the taper leather bag 12 of diverse location heave, thereby due to asymmetric make to pop one's head in 1 deflection appears, namely adjusted the viewing angle of probe, enlarged field of view, strengthen and use motility.And while not needing to adjust viewing angle, can the medium of taper leather bag be extracted out by the medium injection device, the taper leather bag is shunk and restore to the original state, shrink that to be fixed on the heavy hole of spill upper, be convenient to the extraction of probe.

In order to control the amount of injected media, can adopt the mode of quantitative injection, the amount of its injected media just makes taper leather bag 12 heave correct position.In the outfan of the medium injection device 4 of main frame and the junction of media lines 5, also can be added with the pop off valve door, control appearance accident when contingency medium injection device 4, the amount that causes injected media is excessive and while causing pressure to raise, medium can discharge be discharged by the pop off valve door, prevents that pressure medium is excessive and it is unexpected to cause taper leather bag 12 to occur.
