As shown in Figs. 1-5, the embodiment of the present application provides a kind of endoscope apparatus, which can be to be detected The intracorporal target position of person is detected, to judge the target location with the presence or absence of lesion.For example, being filled using the endoscope Setting can detecte with the presence or absence of lesion in the esophagus of person to be detected, hereafter just interior peep as example to provided by the embodiments of the present application Lens device is introduced.

Above-mentioned endoscope apparatus specifically includes release gas source 10, traction tube 20, resilient clamp member 40 and capsule endoscope 60. Discharging gas source 10 can be with output gas, and then generates corresponding active force, such as the release gas source 10 can be syringe (such as Fig. 1 It is shown) or gas injection pump (as shown in Figure 2) etc. structures, with gas outlet.Traction tube 20 is connect with release gas source 10, specifically The one end on ground, traction tube 20 is connected to the gas outlet of release gas source 10, and the gas that release gas source 10 is exported, which enters, to be led In skirt 20；Traction tube 20 can be flexible pipe, can be made of material nontoxic, that property is stable, such as meet biology The silica gel of compatibility, to guarantee its safety, in addition, the outer diameter of traction tube 20 can be set to 0.5~1.5mm, to guarantee to be somebody's turn to do Traction tube 20 will not generate overgenerous foreign body sensation, while will not cut esophagus.Resilient clamp member 40, which can use, to be met The silica gel of biocompatibility is made, and wall thickness can be set to 0.1~0.5mm, which has elasticity, stress After flexible deformation can occur, in the embodiment of the present application, which can produce contraction, the deformation of opening becomes Gesture clamps chamber 41 (referring to Figure 17) with capsule, which clamps chamber 41 and pass through traction tube 20 and the outlet for discharging gas source 10 Mouth is connected；Resilient clamp member 40 and traction tube 20 can use integrally formed manufacture, to guarantee between the two close The material of Feng Xing, the two can not be identical, to optimize respective effect according to the corresponding material of effect flexible choice of the two, Certainly, the two can also be using fit systems such as bondings.That is, the other end of traction tube 20 is connected with resilient clamp member 40 It connects, so that the gas that release gas source 10 exports can enter capsule by traction tube 20 and clamp in chamber 41.

Capsule endoscope 60 is one of the nuclear structure of entire endoscope apparatus, can be entered in the esophagus of person to be detected And along esophagus movement, in the process of movement, the image in the available esophagus of capsule endoscope 60, and then it is convenient for doctor's root Judge the esophagus of person to be detected with the presence or absence of lesion according to the image.In addition, the posture of the capsule endoscope 60 in esophagus can be with It is adjusted, to adjust viewing angle, adjusts capsule endoscope 60 by the modes such as rotating, swing for example, by using mechanical structure and exist The parameters such as the angle in esophagus；The for another example ginseng such as angle using external control system adjustment capsule endoscope 60 in esophagus Number.

Above-mentioned resilient clamp member 40 and capsule endoscope 60 are configured to:

A, as shown in figure 3, in the clamp state, at least part of capsule endoscope 60 is located at capsule and clamps in chamber 41, Resilient clamp member 40 is softened because of the active force by capsule endoscope 60, therefore resilient clamp member 40 has recovery shape at this time Change trend shrinks clamping force P1, under the action of contraction clamping force P1, resilient clamp member 40 to apply to capsule endoscope 60 Frictional force F1 is generated with the contact position of capsule endoscope 60, and what capsule endoscope 60 was subject to is produced from esophagus muscle squeezes Raw expulsion force is F2, at this time F1 > F2, therefore capsule endoscope 60 is firmly clamped by resilient clamp member 40, make its movement by The limitation of traction tube 20.

B, after capsule endoscope 60 completes detection operation, it can discharge capsule endoscope 60, in order to which this is discharged Capsule endoscope.As shown in figure 4, in the released state, discharging 10 output gas of gas source, which enters glue by traction tube 20 Capsule clamps in chamber 41, and since resilient clamp member 40 and capsule endoscope 60 tightly stick together, capsule is clamped in chamber 41 Pressure P2 will be gradually increased, when pressure P2 is reached a certain level, resilient clamp member 40 will open.That is, elastic Clamping element 40 is opened by the gas pressure from traction tube 20, and then, capsule endoscope 60 is no longer influenced by elastic clamping The constraint of part 40, gas will apply thrust F3 to capsule endoscope 60, and subsequent capsule endoscope 60 can be in the work of thrust F3 The abjection of chamber 41 is clamped from capsule with lower.

According to foregoing description it is found that endoscope apparatus provided by the embodiment of the present application connects elastic clip using traction tube 20 Tight part 40, and resilient clamp member 40 can clamp capsule endoscope 60, therefore enter the food of person to be detected in capsule endoscope 60 During road, traction tube 20 connects capsule endoscope 60 always, and operator can control capsule endoscope by traction tube 20 60 motion state, and then extend the time that capsule endoscope 60 is detained in the esophagus of person to be detected, then prevent leakage The problems such as inspection, improves detection accuracy.Meanwhile capsule endoscope 60, when being put into resilient clamp member 40, resilient clamp member 40 will be sent out Raw dilatancy, and then apply to capsule endoscope 60 and shrink clamping force, such clamping mode is more reliable, and then prevents capsule Endoscope 60 is detached from due to active force deficiency with resilient clamp member 40, more reliably extends capsule endoscope 60 with this to be checked The time that survey person's esophagus is detained.

The mode that capsule endoscope 60 is packed into resilient clamp member 40 is relatively more, and the embodiment of the present application provides such as under type:

As shown in figure 5, resilient clamp member 40 can be held with a hand, capsule endoscope 60 is held with another hand, so Drive capsule endoscope 60 close to resilient clamp member 40 afterwards, after capsule endoscope 60 is in contact with resilient clamp member 40, to glue Intracapsular sight glass 60 applies pressing force, so that the pressing force passes to resilient clamp member 40, resilient clamp member 40 is promoted to open, until Capsule endoscope 60 enters capsule and clamps chamber 41, and resilient clamp member 40 can apply to shrink to capsule endoscope 60 and clamp at this time Power.

In further embodiment, as Figure 6-9, one end that traction tube 20 can be connected to resilient clamp member 40 is arranged Circle number for helical structure 21, the helical structure 21 can be 5~10 circles, and the internal diameter of every circle can be equal, helical structure 21 Inside forms capsule accommodating chamber, and the capsule clamping chamber 41 of the capsule accommodating chamber and resilient clamp member 40 is connected, and the two close to Setting.That is, being in capsule accommodating chamber simultaneously after capsule endoscope 60 is installed in capsule clamping chamber 41.It should Helical structure 21 is arranged to gradually scatter under aforementioned clamped state with the movement of capsule endoscope 60.That is, when in capsule Sight glass 60 is slowly moved in esophagus when examinations, which can gradually scatter, and is finally fully deployed, and is unfolded Structure afterwards is as shown in Figure 10.

On the one hand above structure can make the capture range of traction tube 20 bigger, person's swallowable capsule endoscope 60 to be detected After, operator also would not bring obvious foreign body sensation to person to be detected without pulling traction tube 20 repeatedly；Another party Face, traction tube 20 gradually scatter, this will also generate certain buffering for the movement of capsule endoscope 60, and then prevent because of traction When the length of pipe 20 reaches capacity, capsule endoscope 60 stops brought uncomfortable suddenly.Therefore, this helical structure 21 can reach To better detection experience.

The mode for realizing that traction tube 20 slowly scatters has very much, such as can be selected by the material to traction tube 20, makes It had not only had certain flexibility, but be able to maintain it is spiral-shaped, to slowly scatter after being squeezed by esophagus.But in order to more The form of traction tube 20 is accurately controlled, the embodiment of the present application preferably passes through the edible hydrosol and determines helical structure 21 Type.That is, before capsule endoscope 60 enters esophagus, by each circle of edible water-soluble glue sticking helical structure 21, Keeping helical structure 21, its is spiral-shaped, after capsule endoscope 60 is swallowed in esophagus, liquid in esophagus with it is edible It is contacted with the hydrosol, which slowly melts, and helical structure 21 gradually scatters therewith.

The above-mentioned edible hydrosol specifically can be gelatin etc..

As shown in figure 15, the both ends of capsule endoscope 60 can be set to spherical structure 601, and middle section can be set to justify Shell of column 602.As shown in figure 16, resilient clamp member 40 can accommodate spherical structure 601, it might even be possible to extend to cylindrical section 602 It (can specifically extend 0~10mm) at a part, to increase the contact area of the two, promote clamping effect.Helical structure 21 can Being sheathed on the cylindrical section 602, and spaced between helical structure 21 and resilient clamp member 40, i.e., the two is not in contact with each other, so that The process that helical structure 21 gradually the scatters not influence by resilient clamp member 40, ensures the smoothness of entire de-registration, changes Treat the impression of tester in the detection process kindly.

When helical structure 21 is contacted with capsule endoscope 60, and presses capsule endoscope 60, helical structure 21 scatters During will receive the obstruction of capsule endoscope 60；It is when helical structure 21 and capsule endoscope 60 are not in contact with each other, then this Inhibition will reduce, but if distance between the two is larger, helical structure 21 is possible to dissipate too early, too quickly It opens, causes person to be detected to generate uncomfortable.In view of this, the internal diameter of helical structure 21 is more than or equal in optional embodiment The outer diameter of foregoing cylindrical section 602, and the difference of the two is 0~1mm so that helical structure 21 scatter opportunity and speed is more managed Think, while reaching preferably detection experience.

For the winding direction of helical structure 21, there can be following two ways: the first, as illustrated in figs. 11-14, spiral The first lap of structure 21 than helical structure 21 last lap closer to resilient clamp member 40 air inlet, and in traction tube 20 from The part of air inlet of the last lap to resilient clamp member 40 is located at the inside of helical structure 21, and such mode is more conducive to spiral Structure 21 is scattered；Second, as Figure 6-9, the last lap of helical structure 21 than helical structure 21 first lap closer to The air inlet of resilient clamp member 40, such mode are more convenient for being wound.Optionally, as shown in figure 21 and figure, for above-mentioned The second way can also set U-bend folded structure for the part connecting in traction tube 20 with its first lap, U-bend folding The bending place A of structure is located at the inside of the last lap of traction tube 20.Wherein, the knot of U-bend folded structure in the initial state Structure is as shown in figure 21, pulls traction tube 20 according to direction shown in the arrow in Figure 21, can be at tightening shown in Figure 22 State.

As previously mentioned, the both ends of capsule endoscope 60 can be set to spherical structure 601, therefore resilient clamp member 40 is interior Wall is correspondingly arranged as spherical inner wall, and the maximum transversal diameter of the spherical inner wall in its natural state is first diameter, peeps in capsule The maximum transversal diameter for the part (i.e. spherical structure 601) being in contact in mirror 60 with the spherical inner wall is second diameter, this first Diameter is less than second diameter, and first diameter is 5~9mm, and second diameter is 9~20mm.First diameter herein is in spherical shape Maximum gauge of the wall in the cross section of itself, second diameter are that maximum of the capsule endoscope 60 in the cross section of itself is straight Diameter, first diameter are less than second diameter, allow capsule endoscope 60 to strut resilient clamp member 40, then produce therebetween Raw clamping force, and first diameter and second diameter use aforementioned value range, then available clamping force more appropriate.

By above it is found that the contact area between resilient clamp member 40 and capsule endoscope 60 will directly determine between the two Amount of force in order to enable the amount of force is moderate, resilient clamp member 40 therefore can be clamped in the clamp state, Again convenient for release capsule endoscope 60, the embodiment of the present application match resilient clamp member 40 and capsule endoscope 60 in the released state Be set to: in the clamp state, capsule endoscope 60 is located at the volume and capsule endoscope 60 for the part that capsule clamps in chamber 41 Ratio between total volume is 1/5~1/2.

In order to be more convenient for judging that the position of the part of lesion occurs in esophagus, scale can also be set on traction tube 20 Line may determine that the distance between lesion locations and oral cavity according to the graduation mark, then reach foregoing purpose.Specifically, as schemed (unit for the length that graduation mark shown in figure is characterized can be cm) shown in 18 and Figure 19, the graduation mark point on traction tube 20 For the first graduation mark and the second graduation mark, wherein the multiple that the length that the first graduation mark is characterized is 5, the second graduation mark institute table The multiple that the length of sign is 10.In the structure shown in Figure 18, the structure feature of each first graduation mark can be identical, each second quarter The structure feature for spending line can be different, such as can be according to the line of the specific length setting different number of its characterization；In Figure 19 institute In the structure shown, the structure feature of each first graduation mark is identical, and the structure feature of each second graduation mark is identical, but the first scale The structure feature of line and the second graduation mark is different.By this setup, it can be more convenient to operate personal identification graduation mark, into And judge aforementioned location, without be easy to appear because traction tube 20 is smaller be beyond recognition the length that graduation mark is characterized the case where. It is, of course, also possible to distinguish above-mentioned each first graduation mark and the second graduation mark by different colours.

As previously mentioned, the embodiment of the present application provide it is a kind of can be by the speed of service of drawing control capsule endoscope 60 Device, meanwhile, the embodiment of the present application can also be adjusted the posture of capsule endoscope 60.In order to realize the purpose, originally Apply in embodiment, capsule endoscope 60 can use structure as shown in figure 20, and specifically, which includes light Learn transparency cover 61, illumination array 62, camera lens 63, imaging sensor 64, microprocessor 65, magnetic substance 66, battery 67, radio-frequency receiving-transmitting Module 68, dual-mode antenna 69 and shell 610.Optical clear lid 61 and shell 610 form accommodation space, and remaining part is set to this In accommodation space, illumination array 62, camera lens 63, imaging sensor 64 and microprocessor 65 for be imaged and to image at Reason, RF receiving and transmission module 68 and dual-mode antenna 69 are used for transmission data, power when battery 67 works as capsule endoscope 60 Source.Magnetic substance 66 can be permanent magnet or magnetic dipole, and endoscope apparatus can also include control system, the control system packet The part that can be interacted with magnetic substance 66 is included, and then controls the direction of capsule endoscope 60 by magnetic substance 66.In capsule Sensing device built in sight glass 60 can measure magnetic field, and external, control system is transferred data to by way of wireless transmission System can integrate the real-time distribution of capsule endoscope 60 internal data and external magnetic field, determine capsule endoscope 60 in human body in real time In position and capsule endoscope 60 itself posture, to carry out subsequent control.
