Abstract

The utility model discloses a capsule endoscope which comprises an optical shell, a magnetic body and a functional component. The magnetic body and the functional component are arranged at the inner part of the optical shell, and the magnetic body is cylindrical. The provided capsule endoscope has the characteristics that: as the cylindrical magnetic body is adopted, the volume of the magnetic body is increased under the circumstance of adopting the same magnetic body, thereby enhancing the magnetism and improving the positioning as well as driving effects; under the premise of increasing the volume of the magnetic body, more continuous space is provided for the inner part of a capsule, thereby improving the equipment integration level at the inner part of the capsule and simplifying the design of a circuit.

Description

A kind of capsule endoscope

Technical field

This utility model relates to a kind of medical diagnostic equipment, in particular a kind of capsule endoscope.

Background technology

Can not arrive the source of disease place fully for what overcome that pusher endoscope exists, can make patient feel that pain waits problem unbearably again, the lattice texts and pictures have been released capsule endoscope convenient, hommization as company, it can be real-time with the intravital image of people by wireless mode, the great convenience that provides for doctor's diagnosis.

The wireless location of capsule endoscope mainly is divided into location based on radio frequency, based on magnetostatic field or low frequency electromagnetic field.Magnetic orientation is by putting a magnetostatic body in capsule, and it is some to place Hall element then outside human body, with the current capsular position data of the detected data computation of Hall element.

The capsule endoscope of prior art is realized the location or is driven the function modes that adopt embedded rectangle permanent magnet or cylinder permanent magnet (as shown in Figure 1) more, Fig. 2 is the arrange sketch map of cylinder permanent magnet 110 in capsule endoscope, and cylinder permanent magnet 110 and battery, less radio-frequency device, control device and the first-class functional part of shooting is placed side by side in capsule.

Owing in capsule endoscope, be arranged side by side magnet, battery, less radio-frequency device, control device and the first-class parts of shooting, make the size of magnet volume and each parts all be restricted.Under the situation of using identical magnet, the magnetic of magnet is directly proportional with its volume, and therefore, the shape of this cylinder permanent magnet 110 has limited the volume of himself, and then the effect that has influenced the location and driven.Under the constant situation of capsule size, the size of each parts is restricted, make no matter still be efficient from function on, all be not so good as not have the capsule of interior magnet.

Therefore, prior art has yet to be improved and developed.

The utility model content

The purpose of this utility model is to provide a kind of capsule endoscope, the volume of the increase magnet of this capsule endoscope, enhancing magnetic, optimization capsule space.

The technical solution of the utility model is as follows:

A kind of capsule endoscope comprises the optics shell, is arranged on the magnet and the functional part of described optics enclosure, and described magnet is a cylinder magnet.

Described capsule endoscope, wherein, described cylinder magnet is close to described optics shell.

Described capsule endoscope, wherein, described functional part is arranged in this cylinder magnet.

Described capsule endoscope, wherein, the two poles of the earth of described cylinder magnet are positioned at its radial two ends.

Described capsule endoscope, wherein, the two poles of the earth of described cylinder magnet are positioned at its axial two ends.

Capsule endoscope provided by the utility model, owing to adopted cylinder magnet, compared with prior art, under the situation of same magnets, increased magnet volume, also strengthened magnetic, because for identical magnet, its magnetic is directly proportional with its volume, and then the effect that has improved the location and driven; Under the prerequisite that increases magnet volume, for capsule provides more continuous space, arranging of functional part can improve the internal unit integrated level, simplify circuit design in tube or outside the tube.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is done and to be specified.

The capsule endoscope of present embodiment comprises optics shell 200, is arranged on the magnet and the functional part of described optics shell 200 inside.Described magnet is a cylinder magnet 210, sees Fig. 3 and 4; Can under the situation that does not increase magnet volume, provide more inner continuous space like this, improve the internal unit integrated level.Functional part arrange can within the cylinder magnet 210 or outside, as preferably, cylinder magnet 210 is close to optics shell 200 and is provided with, and this structure can be accomplished maximum as far as possible with the volume of cylinder magnet 210, further improve the internal unit integrated level, simplified the design of circuit; This can do the volume of capsule endoscope littler under the certain situation of required magnetic, is convenient to microminiaturization, the sense of discomfort when reducing to use.

The two poles of the earth of cylinder magnet 210 are positioned at its radial two ends among Fig. 3, i.e. the cylinder magnet 210 of axial charging; The two poles of the earth of cylinder magnet 210 are positioned at its radial two ends among Fig. 4, i.e. the cylinder magnet 210 of radial magnetizing; Because the magnetizing direction of magnet 210 is radial magnetizings, when capsule endoscope during along the rotation of its symmetrical centre axle, space some magnetic induction, direction at place all can change, so the external magnetic pick off can the perception capsule endoscope axially rotatablely moves; Therefore this capsule endoscope accurate location that can realize three-dimensional position and three-dimensional in the magnetic induction and the direction of the permanent magnet that only utilizes radial magnetizing.

Cylinder magnet 210 of the present utility model can adopt permanent magnet, also can adopt non-permanent magnet, and the material of cylinder magnet 210 can be different.Inner each functional part of capsule endoscope can optionally increase or delete, perhaps uses the parts that can finish identical or similar functions.

The capsule endoscope structure as shown in Figure 5, main functional part comprises: optical lens 220, CMOS photographic head 230, illumination LED 240, control device 250, antenna 260, less radio-frequency device 270, pick off 280, battery 290.Wherein cylinder magnet 210 is used to provide the location and drives function; Optical lens 220 is used to receive light and focuses on; Illumination LED 240 is used to provide takes required illumination; CMOS photographic head 230 is used for imaging; Less radio-frequency device 270 and antenna 260 are used for the transmission of view data and receive data and the instruction that external equipment sends; Control unit 250 is used for shooting, compression and the transmission of control figure picture; Pick off 280 is used to gather physiological parameters such as digestive tract temperature, pressure and pH value; Battery 290 is used for above-mentioned each parts power supply.

Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection domain of this utility model claims.
