Detailed Description
The magnetic swallowable endoscope of the present application will be described in detail below with reference to the drawings.
The magnetic swallowable endoscope of the present application does not make any improvement in function and circuit structure with respect to CN 209331993U and CN 210055950U, but the endoscope capsule is designed in two parts that can be separated under control, thereby allowing the magnetic swallowable endoscope with conduit to be separated after a certain position of travel, for example, when the conduit is not suitable for further insertion, and the separated part can be further traveled and examined by using an external magnetic field.
The magnetic swallowable endoscope of the present application includes an endoscope capsule and a catheter 21; the guide tube 21 is connected to the rear end of the endoscope capsule; the endoscope capsule comprises a lens, an image sensor, an illuminating device, a first magnet, a wireless transmission module and a battery, and is used for image acquisition, which are all in the prior art and are not described again; the catheter 21 houses a guide wire therein, as is also known in the art. After the first part 61 and the second part 62 are separated, the power supply of the capsule is replaced by a battery, and the data transmission of image acquisition is completed by a wireless transmission module.
The endoscopic capsule comprises a first portion 61 and a second portion 62.
The lens, the image sensor, the lighting device, the first magnet, and the wireless transmission module are installed in the first portion 61.
The second part 62 forms the rear end of the endoscope capsule, to which second part 62 the guide tube 21 is connected.
The first part 61 and the second part 62 are joined together by magnetic force.
The rear end of the first portion 61 forms a first interface 63; the front end of the second portion 62 forms a second interface 64; the second portion has a second magnet 67 formed therein, and a coil 671 is formed outside the second magnet 67.
In one embodiment, as shown in fig. 1 and 2, a first attraction part 65 and a second attraction part 66 may be respectively disposed at the connection position of the first part and the second part, the first attraction part 65 corresponds to the second attraction part 66, at least one of the first attraction part 65 and the second attraction part 66 is a permanent magnet, and the other is a ferromagnetic substance or a permanent magnet with opposite polarity, so that the first part 61 and the second part 62 are attracted together.
In another embodiment, a coupling force is formed between the first part 61 and the second part 62 by a magnetic field formed by the first magnet and/or a magnetic field formed by the second magnet, whereby the first part 61 and the second part 62 are attracted together, the first port 63 is coupled with the second port 64, and the first part 61 communicates with the outside through a wire in the catheter 21.
By supplying power to the coil 671 outside the second magnet 67, the coupling force between the first part 61 and the second part 62 is weakened or a repulsive force is formed between the first part 61 and the second part 62, whereby the first part 61 is separated from the second part 62, and the first part communicates with the outside through the wireless transmission module.
The first interface 63 and the second interface 64 are coupled together by plugging, as shown in fig. 1.
The first and second headers 63 and 64 are coupled together by contact, as shown in fig. 2, when one of the first and second headers 63 and 64 is a resilient contact terminal.
In the embodiment in which the first and second portions 61 and 62 are coupled together by the first and second magnets 67, there are various ways as long as the attraction force therebetween can be formed and the attraction force therebetween can be weakened by the coil 671 outside the second magnet 67 and even the repulsive force can be generated therebetween. For example, the first magnet is a ferromagnetic substance, the second magnet is a permanent magnet, when the coil is not electrified, enough attraction force exists between the first magnet and the second magnet, when the coil is electrified, the magnetic force generated by the coil is opposite to the magnetic force direction of the second magnet, and the attraction force between the first magnet and the second magnet is weakened, so that the binding force between the first part and the second part is weakened, and the catheter can be pulled from the back to separate the first part and the second part; the first magnet can also be a permanent magnet or an electromagnet, and the second magnet can be a ferromagnetic substance (such as iron) or a permanent magnet in the same direction as the first magnet, so that when the coil is not electrified, the first magnet and the second magnet are attracted, and the first part and the second part are combined together; when the coil is electrified, reverse magnetic force is generated, the binding force between the first magnet and the second magnet is weakened, and even the repulsive force generated by the coil and the first magnet is larger than the attractive force between the first magnet and the second magnet, so that the first part is separated from the second part.
When in use, the first part and the second part are combined to perform examination of digestive tract and stomach, i.e. gastroscopy, in the same way as CN 209331993U and CN 210055950U; when the intestinal examination is needed, the coil outside the second magnet is electrified, so that the first part is separated from the second part, the first part continues to move downwards by using an external magnetic field or the peristalsis of the intestine, and the shot image is sent to the outside through the wireless communication module during the movement.
