In this utility model, the center of gravity of described capsule endoscope does not overlap mutually with the axle center.The center of gravity of described capsule endoscope and the deviation between the axle center are less than 1mm.
In order to make the center of gravity and the axle center of capsule endoscope not overlap, in a side of described battery weighted item is installed, described weighted item is coil or becket, described coil or becket are wound on the battery.Preferably, the weight of described weighted item is 0.2-0.6g.
The density of described capsule endoscope is slightly less than the density of body fluid, and preferably, the density of described capsule endoscope is slightly less than water, i.e. 1.0kg/m
3
Described capsule endoscope is applicable to that preferably gastroscope detects.
Preferably, described capsule endoscope is provided with two camera lenses, is divided into the two ends of capsule housing, and described battery is arranged at the middle part of capsule endoscope.Take gastric multi-angle images or image synchronously by twin-lens, enlarged the scope of taking.
Compared with prior art, this utility model capsule endoscope is by being provided with weighted item on its half side limit, make the two halves capsule be the not reciprocity structure of weight, its axle center and center of gravity do not overlap, and when capsule endoscope moved under one's belt, it stood vertically and float among the body fluid, owing to its center of gravity is kept upright on the lower side, then can judge captured image or image zone or position under one's belt comparatively exactly,, further help to make a definite diagnosis and treat to help accurately to judge each regional coat of the stomach situation of stomach.Described weighted item adopts coil or becket to be sheathed on the battery, and its assembling is simple, and can require to be adjusted to suitable weight voluntarily according to weight, does not influence the work of other accessories.By allowing capsule endoscope keep vertically floating, also externally under the action of a magnetic field, stressed to definite direction operation, in the image that photographs each angle and the checkout equipment that is sent to the outside, carry out omnibearing detection.In addition,, replaced original single-lens capsule endoscope,, increased coverage at stomach by the shooting of multi-angle by twin-lens being set at two ends.
Description of drawings
Fig. 1 is the structural representation of this utility model capsule endoscope.
The specific embodiment
With reference to shown in Figure 1, this utility model provides a kind of self hang down type capsule endoscope, comprise capsule housing 1 and be encapsulated in wherein led light source 2, pick off 3, camera lens 4, lens case 5 and battery 6, described lens case 5 is located at camera lens 4 peripheries, described battery 6 respectively with led light source 2, pick off 3, camera lens 4 is electrically connected, described capsule endoscope is the center with the axis, wherein half capsular weight is greater than second half capsular weight, move down by center of gravity capsule endoscope, make to keep vertical when capsule moves in body fluid, camera lens 4 parallels with capsular traffic direction.
In order to make capsule endoscope in body fluid, when particularly in human stomach, moving, can be kept upright in the body fluid and vertically move, it is downward that capsule endoscope is arranged to centre-of gravity shift, and center of gravity and axle center do not overlap mutually, in the present embodiment, with reference to shown in Figure 2, the axle center of described capsule endoscope is at the A point, and center of gravity is at the B point, and described axle center A point and center of gravity B point are on same longitudinal axis Y-axis.When capsule endoscope uprightly floats in the body fluid, center of gravity B point is under axle center A point, the center of gravity of whole capsule endoscope on the lower side, make its held stationary, erectly floating in body fluid, because the angle of taking is relatively stable, then can from the image taken or image, judge the zone of being clapped, to help accurately judging each regional wall situation of gastric.In this utility model, the center of gravity of described capsule endoscope and the deviation between the axle center are in the 1mm.
In order to make the centre-of gravity shift of capsule endoscope downward, when vertically floating in the body fluid, be equiped with weighted item 7 on the Lower Half of described battery, by setting up weighted item 7 in the capsule endoscope Lower Half, increase the weight of capsule endoscope Lower Half, make it vertically float when standing in the body fluid, center of gravity moves down, floating steadily, the shooting angle stable and controllable has improved and has taken pictures or the recognizability of image.Wherein, described weighted item 7 is coil or becket, and described coil or becket are wound on the battery 6.In the mode that coil or becket twine, install more conveniently, can adjust according to the deadweight of capsule endoscope, and, be wound on the battery, do not influence the use of battery, not area occupied.The weight of described weighted item is 0.2-0.6g.Described weighted item 7 is not limit by this at the mounting means of capsule endoscope, as long as it can be installed on the capsule endoscope, and make two halves constitute weight not peering structure get final product.
In this utility model, when described weighted item 7 was coil, the number of turn of described coil was 20 circles.The density of described capsule endoscope is 0.8-0.95kg/m
3, its density is slightly less than the density of water, promptly less than 1.0kg/m
3, it can steadily and vertically be suspended in the body fluid.Described capsule endoscope is applicable to that mainly gastroscope detects, make when capsule endoscope moves in human gastric juice, the suspended state of being kept upright, then pass through the zone of decidable stomach in captured photo or the image, to judge the situation of determining the coat of the stomach face on the zone, make diagnosis person can know the pathological condition of judging each position in the stomach.
In this utility model, described capsule endoscope is provided with two camera lenses, is divided into the two ends of capsule housing, and described battery is arranged at the middle part of capsule endoscope.By on battery, setting up or winding around or becket, make capsule endoscope constitute the unequal structure of weight of the first half and Lower Half, the center of gravity of capsule endoscope moves down, and it is moved in body fluid be kept upright and steadily.By being divided into the camera lens at capsule endoscope two ends, take the wall at gastric two ends respectively, enlarged coverage, make that image or the image capturing range taken are wider, be beneficial to the various situations in the comprehensive judgement coat of the stomach.
This utility model capsule endoscope is by being provided with weighted item on its half side limit, make the two halves capsule be the not reciprocity structure of weight, its axle center and center of gravity do not overlap, when capsule endoscope moves under one's belt, it stands vertically and floats among the body fluid, owing to its center of gravity is kept upright on the lower side, then can judge captured image or image zone or position under one's belt comparatively exactly, to help accurately to judge each regional coat of the stomach situation of stomach, further help to make a definite diagnosis and treat.Described weighted item adopts coil or becket to be sheathed on the battery, and its assembling is simple, and can require to be adjusted to suitable weight voluntarily according to weight, does not influence the work of other accessories.By allowing capsule endoscope keep vertically floating, also externally under the action of a magnetic field, stressed to definite direction operation, in the image that photographs each angle and the checkout equipment that is sent to the outside, carry out omnibearing detection.In addition,, replaced original single-lens capsule endoscope,, increased coverage at stomach by the shooting of multi-angle by twin-lens being set at two ends.
