Detailed Description

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

It will be understood that terms such as "upper," "lower," "outer," "inner," and the like, used herein to denote relative spatial positions, are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

In the various drawings of the present invention, some dimensions of structures or portions are exaggerated relative to other structures or portions for convenience of illustration, and thus, are used only to illustrate the basic structure of the subject matter of the present invention.

Referring to fig. 1, a capsule endoscope according to a preferred embodiment of the present invention includes a housing 10, a camera assembly 20 disposed in the housing 10, and a driving mechanism 30 in transmission connection with the camera assembly 20. In this embodiment, the photographing assembly 20 is installed in the housing 10, so as to avoid being damaged by external force when entering the digestive tract. Moreover, the housing 10 has a good sealing performance, so that liquid can be prevented from permeating into the housing, and the shooting assembly 20 can work normally. In order to ensure the driving mechanism 30 can work normally, the driving mechanism 30 is also arranged in the housing 10. Of course, in some embodiments, the drive mechanism 30 may be disposed outside the housing 10.

Specifically, the housing 10 includes a front housing for accommodating the camera module 20, and a rear housing connected to the front housing and provided with the driving mechanism 30, and the front housing is made of a transparent material. In this embodiment, the housing 10 is formed by splicing at least two parts, namely a front housing and a rear housing, so as to facilitate the installation of an internal structure; the splicing position is adaptively designed according to the requirement, and the splicing position is also shown in the figure. The front shell and the rear shell are bonded and fixed through UV glue, so that the sealing of the inner space is ensured, and the shooting assembly 20 and the driving mechanism 30 are prevented from being soaked by liquid during working. The shell 10 is made of a material which is biocompatible and cannot be corroded by digestive juice, and can be directly exposed to internal organs of a human body for use, so that the healthy use of a patient is ensured. The photographing module 20 in the housing 10 can clearly photograph through the front case.

The camera assembly 20 is capable of capturing a view of the front side of the capsule endoscope as well as the side of the capsule endoscope such that the field of view of the capsule endoscope covers at least the forward and lateral directions of the housing 10, thereby capturing a larger field of view.

The current required to rotate the camera assembly 20 and the drive mechanism 30 can be supplied by a power source internal to the capsule or by a power source external to the capsule.

Specifically, the camera assembly 20 includes a rotating mechanism 21 rotatably disposed in the housing 10. In this embodiment, the rotating mechanism 21 can rotate in the housing 10 after being driven by the driving mechanism 30, and the whole shooting assembly 20 rotates around the rotation axis of the rotating mechanism 21, that is, the rotation axis of the shooting assembly 20 is collinear with the rotation axis of the rotating mechanism 21.

Further, the capsule endoscope also comprises a transmission assembly 40 which is in transmission connection with the driving mechanism 30 and the rotating mechanism 21. In this embodiment, the transmission assembly 40 is disposed in the housing 10, and the driving mechanism 30 and the rotating mechanism 21 are driven by the transmission assembly 40, so that the driving mechanism 30 drives the rotating mechanism 21 to rotate more stably, thereby ensuring the stability of the shooting assembly 20 during the rotation shooting and improving the imaging effect of the shooting assembly 20 during the rotation shooting.

Further, the rotation axes of the driving mechanism 30 and the rotation mechanism 21 are parallel to the axis of the housing 10. In the present embodiment, the rotation axis of the rotation mechanism 21 is collinear with the axis of the housing 10, that is, the photographing assembly 20 rotates around the central axis of the housing 10, so that the lateral field of view when the photographing assembly 20 rotates to photograph is uniform around the lateral direction of the housing 10. Of course, in some embodiments, it may be that the axis of rotation of the drive mechanism 30 is collinear with the axis of the housing 10.

Further, the rotation axis of the driving mechanism 30 and the rotation axis of the rotating mechanism 21 are spaced apart from each other in the radial direction of the housing 10. In this embodiment, since the rotation axis of the driving mechanism 30 is not collinear with the rotation axis of the rotating mechanism 21, the driving mechanism 30 and the shooting assembly 20 can be arranged along the radial direction of the housing 10 when being arranged, so that the space of the driving mechanism 30 and the shooting assembly 20 in the axial direction of the housing 10 is saved, the length of the capsule endoscope along the axial direction is reduced, the capsule endoscope is convenient for swallowing or excreting of a patient, and discomfort is not brought to the patient due to the overlarge outer diameter of the capsule endoscope.

Through setting up transmission assembly 40 between rotary mechanism 21 and actuating mechanism 30 for rotary mechanism 21 and actuating mechanism 30 set up along the radial interval of casing 10, can practice thrift the inner space of casing 10 along the axis direction, do benefit to the swallowing or the discharge of capsule endoscope, promote patient's use experience.

Specifically, the transmission assembly 40 includes a first transmission member 41 connected to the driving mechanism 30, and a second transmission member 43 connected to the rotating mechanism 21 and engaged with the first transmission member 41. In the present embodiment, the first transmission member 41 rotates with the rotation of the driving mechanism 30, and the rotation axis of the first transmission member 41 is collinear with the rotation axis of the driving mechanism 30, so that the space occupied by the first transmission member 41 and the driving mechanism 30 in the radial direction of the housing 10 can be saved. Similarly, the rotation mechanism 21 rotates along with the rotation of the second transmission piece 43, and the rotation axis of the second transmission piece 43 is collinear with the rotation axis of the rotation mechanism 21, so that the occupied space of the second transmission piece 43 and the rotation mechanism 21 in the radial direction of the shell 10 can be saved. Moreover, the first transmission member 41 stably transmits the torque output by the driving mechanism 30 to the second transmission member 43, and then the second transmission member 43 drives the rotating mechanism 21 to rotate, so that the whole shooting assembly 20 rotates together with the rotating mechanism 21.

Further, the rotation axes of the first transmission piece 41 and the second transmission piece 43 are parallel to the rotation axis of the rotation mechanism 21. In the present embodiment, the rotation axis of the first transmission member 41 and the rotation axis of the second transmission member 43 are parallel to each other and to the axis of the casing 10, so as to save the space occupied by the transmission assembly 40 in the axial direction of the casing 10. Moreover, since the rotation axis of the driving mechanism 30 and the rotation axis of the rotating mechanism 21 are parallel to each other, the rotation axes of the first transmission member 41, the second transmission member 43, the driving mechanism 30 and the rotating mechanism 21 are all parallel to the axis of the housing 10, so that the torque loss generated by transmission is small in the process that the driving mechanism 30 drives the rotating mechanism 21 to rotate by using the transmission assembly 40, thereby reducing the energy consumption of the capsule endoscope.

Specifically, the first transmission member 41 and the second transmission member 43 are both configured as spur gears. In this embodiment, the first transmission member 41 and the second transmission member 43 both adopt spur gears, so that the installation and the cooperation of the transmission assembly 40 are simplified while the torque is stably transmitted, and the manufacturing cost is saved. Of course, the transmission assembly 40 may also adopt a chain transmission or a belt transmission to realize the mutual matching rotation of the first transmission member 41 and the second transmission member 43.

Of course, in some embodiments, the rotation axis of the first transmission piece 41 and the rotation axis of the second transmission piece 43 may be perpendicular to each other. In this way, the transmission assembly 40 may transmit the torque of the driving mechanism 30 to the rotating mechanism 21 by using a worm gear and a worm gear which are engaged with each other and a bevel gear which is engaged with each other.

Referring to fig. 2, further, the transmission ratio of the first transmission member 41 to the second transmission member 43 is greater than 1. In this embodiment, the transmission ratio between the first transmission member 41 and the second transmission member 43 is configured to be greater than 1, so that when the rotation speed output by the driving mechanism 30 is transmitted to the rotating mechanism 21 through the transmission assembly 40, the rotation speed output by the driving mechanism 30 is reduced, thereby reducing the rotation speed of the rotating mechanism 21 and avoiding the influence on the shooting effect caused by the over-fast rotation of the shooting assembly 20.

Further, the camera assembly 20 further includes at least two side cameras 23 facing outward in a radial direction of the housing 10. In this embodiment, the setting of a plurality of side cameras 23 for shoot subassembly 20 need not to rotate 360 and can accomplish around the hoop shooting of casing a week, thereby under the condition of equal angular velocity, shoot subassembly 20 and accomplish the time of hoop shooting shorter, then improve the speed of shooting subassembly 20 hoop shooting.

Specifically, the aforementioned at least two side cameras 23 are circumferentially uniformly arranged around the rotation axis of the rotation mechanism 21. In this embodiment, the distances between the plurality of side cameras 23 and the axis of the housing 10 are equal, so that the distance between each side camera 23 and the inner wall of the housing 10 is equal, and thus, each side camera 23 can be adjusted to have the same focal length or be provided with the same lens. Moreover, the plurality of side cameras 23 are all circumferentially and uniformly arranged around the axis of the housing 10, that is, the distances between adjacent side cameras 23 are equal, so that the visual field formed by the plurality of side cameras 23 uniformly surrounds the lateral direction of the housing 10. In addition, this way arranges the plurality of side cameras 23, facilitating manufacture and assembly, thereby reducing the manufacturing cost of the photographing assembly 20.

Further, the transmission ratio of the first transmission piece 41 to the second transmission piece 43 corresponds to the number of the side cameras 23. In this embodiment, the ratio of the transmission ratios of the first transmission member 41 and the second transmission member 43 is equal to the number of the side cameras 23, that is, as the number of the side cameras 23 increases, the ratio of the transmission ratios of the first transmission member 41 and the second transmission member 43 increases, so that the angle of rotation of the second transmission member 43 decreases under the same angle of rotation of the first transmission member 41. Therefore, under the condition that the rotating speed of the first transmission piece 41 is not changed, the rotating speed of the shooting assembly 20 can be reduced by setting the transmission ratio matched with the number of the side cameras 23, and the effect of rotary shooting of the shooting assembly 20 is improved.

Specifically, the shooting assembly 20 includes two side cameras 23, and the transmission ratio of the first transmission member 41 to the second transmission member 43 is set to 2. In this embodiment, the shooting assembly 20 is configured with the least number of side cameras 23, that is, two side cameras 23, so that the outer diameter of the shooting assembly 20 at the side cameras 23 can be reduced to the greatest extent, and the distance between the side cameras 23 and the inner wall of the housing 10 is increased to the greatest extent, so that the side cameras 23 have a better forming effect when shooting a close shot. According to the number of the side cameras 23, the ratio of the transmission ratio of the first transmission piece 41 to the second transmission piece 43 is configured to be 2, at this time, the first transmission piece 41 rotates 360 ° and simultaneously drives the second transmission piece 43 to rotate 180 ° correspondingly, and after the rotating mechanism 21 rotates 180 ° together with the second transmission piece 43, the sum of the visual fields swept by the two side cameras 23 is exactly equal to 360 °, so as to realize the circular panoramic shooting of the shooting assembly 20 around one lateral circle of the housing 10.

Specifically, as shown in fig. 2, when the ratio of the transmission ratio of the first transmission member 41 to the second transmission member 43 is configured to be 2, the diameter of the first transmission member 41 is one half of the diameter of the second transmission member 43, and the gear ratio of the first transmission member 41 to the second transmission member 43 is one half, that is, the first transmission member 41 and the second transmission member 43 have meshing teeth with the same tooth width, and the number of teeth of the first transmission member 41 is one half of the number of teeth of the second transmission member 43.

Specifically, the driving mechanism 30 includes a motor 31 disposed in the housing 10 and a speed reducer 33 connected to the motor 31, and the first transmission 41 is connected to an output shaft 33a of the speed reducer 33. In this embodiment, the speed reducer 33 is in transmission connection with the motor 31, so that the motor 31 can change the output torque or the output speed as required while ensuring stable output torque of the motor 31. The motor 31 is selected from a slender hollow cup motor or other stepping motors. After the output rotation speed of the motor 31 is changed, the reducer 33 outputs the torque to the outside through the output shaft 33a, wherein the output shaft 33a is fixedly connected with the first transmission member 41, so that the first transmission member 41 rotates along with the output shaft 33 a.

With reference to fig. 2, the capsule endoscope further includes a first limiting member 50 connected to the output shaft 33a of the speed reducer 33, and a second limiting member 60 connected to the speed reducer 33 and engaged with the first limiting member 50. In this embodiment, the first limiting member 50 and the second limiting member 60 are arranged to limit the rotation angles of the output shaft 33a and the first transmission member 41, so as to avoid that the shooting assembly 20 rotates excessively to shoot repeated images, thereby facilitating an operator to more accurately obtain the annular panoramic image. The rotation range of the output shaft 33a and the first transmission member 41 is set to rotate between 0 ° and 360 ° in the clockwise or counterclockwise direction. The first limiting member 50 is fixedly connected to the output shaft 33a, the second limiting member 60 is fixedly connected to the speed reducer 33, and when the first limiting member 50 and the second limiting member 60 abut against each other, the output shaft 33a cannot rotate continuously, so that the first transmission member 41 also stops rotating, and the rotation of the speed reducer 33 can be directly cut off. When the first stopper 50 is disposed on the first transmission 41, the first transmission 41 stops rotating, but torque force still exists between the output shaft 33a and the first transmission 41, and damage to the first transmission 41 is avoided. Of course, the first limiting member 50 may also be fixedly connected to the first transmission member 41 or the second transmission member 43.

Specifically, the first limiting member 50 and the second limiting member 60 are located on the same side of the first transmission member 41. In this embodiment, the first limiting member 50 and the second limiting member 60 are both disposed on one side of the first transmission member 41 facing the speed reducer 33, so that when the first limiting member and the second limiting member 60 are not in contact, the output shaft 33a can normally rotate.

Specifically, the maximum distance between the first limiting member 50 and the output shaft 33a of the speed reducer 33 is greater than the minimum distance between the second limiting member 60 and the output shaft 33a of the speed reducer 33, so that when the first limiting member 50 rotates to the position of the second limiting member 60 along with the output shaft 33a of the speed reducer 33, the first limiting member 50 and the second limiting member 60 abut against each other. In this embodiment, as shown in fig. 2, the first limiting member 50 has a fixed end connected to the output shaft 33a and a free end away from the fixed end, and the second limiting member 60 has a first end close to the output shaft 33a and a second end away from the output shaft, because the first limiting member 50 and the second limiting member 60 are located at a side of the first transmission member 41 facing the speed reducer 33, as long as the distance between the free end and the output shaft 33a is greater than the distance between the first end and the output shaft 33a, the first limiting member 50 and the second limiting member 60 will inevitably abut against each other when the first limiting member 50 rotates to the second limiting member 60. When the first limiting member 50 and the second limiting member 60 abut against each other, the output shaft 33a cannot rotate continuously in the original rotation direction, but only rotates in the opposite direction away from the second limiting member 60. Therefore, the first limiting member 50 can abut against two ends of the second limiting member 60, so that the first transmission member 41 can rotate clockwise by 0-360 degrees or counterclockwise by 0-360 degrees, and then the second transmission member 43 can be driven to rotate by a corresponding angle.

Further, the capsule endoscope further includes a mounting tube 70 provided in the housing 10 and extending in the axial direction of the housing 10. In this embodiment, the mounting tube 70 is fixed in the housing 10, preferably on the rear shell, and the cross section of the mounting tube is circular ring type, and the inside is hollow structure. After the mounting tube 70 is secured within the housing 10, the axis of the mounting tube 70 and the axis of the housing 10 are co-linear with each other.

Further, the rotating mechanism 21 includes a rotating base 21a connected to the second transmission member 43 and engaged with the mounting tube 70. In this embodiment, rotary base 21a is rotatable about mounting tube 70 so that the axis of rotation of rotary base 21a and axis 70 of the mounting tube are collinear with each other and the axis of rotation of rotary base 21a and the axis of rotation of rotary mechanism 21 are collinear with each other. The second transmission member 43 is fixedly connected to the rotating base 21a, so that the second transmission member 43 and the rotating base 21a rotate together around the mounting pipe 70. During the specific setting, the second transmission piece 43 and/or the rotary seat 21a are directly sleeved on the installation pipe 70, or the second transmission piece 43 and/or the rotary seat 21a are rotatably arranged on the installation pipe 70 through a rotary bearing, as long as the second transmission piece 43 and the rotary seat 21a can rotate around the installation pipe 70 together.

Further, the capsule endoscope further includes a third limiting member 80 and a fourth limiting member 90 connected to the mounting tube 70 and disposed oppositely along the axial direction of the mounting tube 70, the third limiting member 80 abuts against one side of the rotating base 21a departing from the second transmission member 43, and the fourth limiting member 90 abuts against one side of the second transmission member 43 departing from the rotating base 21 a. In this embodiment, the third limiting member 80 and the fourth limiting member 90 are both fixedly connected to the mounting tube 70, so that the second transmission member 43 and the rotating base 21a are limited between the third limiting member 80 and the fourth limiting member 90, and then the second transmission member 43 and the rotating base 21a are limited from shifting along the axial direction of the housing 10, thereby ensuring that the shooting assembly 20 rotates stably.

Further, the rotating mechanism 21 further includes a mounting seat 21b connected to the rotating seat 21a and fixing the side camera 23. In this embodiment, the mounting seat 21b is preferably a tubular structure with a circular cross section, and the plurality of side cameras 23 are disposed on the outer circumferential surface of the mounting seat 21 b. The mount 21b rotates together with the rotary base 21 a.

Further, the camera assembly 20 further includes at least one front camera 25 fixed on the mounting seat 21b and facing forward along the axial direction of the housing 10, a plurality of front illuminators 27 disposed on the rotating mechanism 21 and facing the front camera 25, and a plurality of side illuminators 29 disposed on the rotating mechanism 21 and facing the side cameras 23. In the embodiment, the front camera 25 is arranged to provide a forward view for an operator, and on one hand, the front camera 25 is matched with the side camera 23 to provide a sufficiently large view range for the capsule endoscope; on the other hand, the front camera 25 also provides the operator with intuitive information of the general orientation in which the capsule endoscope is located, as the scope-feed field to which the endoscope operator is accustomed. To save manufacturing costs, one front camera 25 is preferred. Of course, in some embodiments, the camera assembly 20 can be configured with a plurality of front cameras 25 for co-rotation with the camera assembly 20. The front illuminating part 27 is provided for illuminating the front camera 25 for photographing, and the side illuminating part 29 is provided for illuminating the side camera 23 for photographing, so as to improve the imaging effect of the capsule endoscope and facilitate the doctor to clearly obtain the condition of the part to be inspected. The front lighting 27 and the side lighting 29 are preferably LEDs.

Specifically, each front illuminator 27 is equidistant from the axis of the housing 10, and each side illuminator 29 is equidistant from the axis of the housing 10. In this embodiment, when the plurality of front illuminating members 27 and the plurality of side illuminating members 29 rotate with the photographing assembly 20 around the axis of the housing 10, the distance between each front illuminating member 27 and each side illuminating member 29 and the inner wall of the housing 10 is equal, so as to ensure that the intensity and brightness of light emitted to the outside of the housing 10 by each illuminating member are the same.

Specifically, the rotating mechanism 21 further includes a first mounting frame 21c connecting the rotating base 21a and the mounting base 21b, a second mounting frame 21d connecting the mounting base 21b and disposed opposite to the first mounting frame 21c around the side camera 23, and a third mounting frame 21e connecting the mounting base 21b and located on one side of the second mounting frame 21d departing from the side camera 23. In this embodiment, the first mounting frame 21c is fixedly connected to the rotating base 21a through a bracket at an outer edge, and the mounting base 21b is fixed at a center of the first mounting frame 21c, so that the mounting base 21b and the first mounting frame 21c rotate together with the rotating base 21 a. The second and third mounting brackets 21d and 21e are fixedly attached to the outer circumference of the mounting base 21b and also rotate together with the rotating base 21 a.

Further, the plurality of front illuminators 27 are uniformly disposed on the third mounting frame 21e around the axis of the housing 10, and the plurality of side illuminators 29 are uniformly disposed on the first mounting frame 21c and/or the second mounting frame 21d around the axis of the housing 10. In this embodiment, the first mounting frame 21c and the second mounting frame 21d, which are oppositely arranged, are provided with the side illumination members 29, so as to provide an illumination effect for the side camera 23. The side illuminating piece 29 is arranged on the second mounting frame 21d, and the front illuminating piece 27 is arranged on the third mounting frame 21e, so that the front illuminating piece 27 and the side illuminating piece 29 can be conveniently and independently replaced or maintained at a later stage. Of course, in some embodiments, the second mounting frame 21d and the third mounting frame 21e may also be integrally formed, so as to save the occupied space of the photographing assembly 20.

Moreover, the side illuminating pieces 29 arranged on the first mounting frame 21c and the second mounting frame 21d and the front illuminating piece 27 arranged on the third mounting frame 21e are circumferentially and uniformly arranged around the axis of the shell 10, so that the illuminating light generated by the illuminating pieces uniformly surrounds the periphery of the shell 10, and the same light brightness and illumination range at all positions in annular panoramic shooting are ensured.

Further, the capsule endoscope further comprises a lead 10a electrically connected with the shooting assembly 20 and a magnetic member 10b arranged in the shell 10. In this embodiment, the conducting wire 10a is connected to a power supply inside the housing 10 or outside the housing 10 to supply current to the camera assembly 20. The magnetic part 10b is arranged, when the capsule endoscope is positioned in a patient body, an operator adjusts the position of the magnetic part 10b by means of an external magnetic control device or a handheld magnetic control device, so that the position of the capsule endoscope is changed, the posture of the capsule endoscope can be adjusted, and the inspection efficiency of the capsule endoscope is improved.

Specifically, the lead wire 10a is inserted into the installation tube 70. In this embodiment, after the lead wire 10a is disposed in the mounting tube 70, interference with the photographing assembly 20 and the transmission assembly 40 in the housing 10 is avoided, and normal operation of the capsule endoscope is ensured. Moreover, when the first limiting member 50 and the second limiting member 60 limit the rotation angle range of the output shaft 33a or the first transmission member 41, the problem that the wire 10a is wound around the mounting tube 70 due to over rotation of the photographing assembly 20 and the photographing assembly 20 cannot continue to work can be avoided.

Specifically, the magnetic member 10b is disposed opposite to the driving mechanism 30 around the mounting tube 70. In this embodiment, the magnetic member 10b and the driving mechanism 30 are disposed at two sides of the axis of the casing 10, so that the internal space of the casing 10 is reasonably utilized, and the two sides of the axis of the capsule endoscope are kept in weight balance, i.e., the magnetic member 10b is used to balance the weight of the driving mechanism 30, thereby ensuring that the shooting assembly 20 can rotate smoothly and avoiding deviation.

Referring to fig. 3, the present invention also provides a capsule endoscope including the pulling assembly 100 and as described above. In this embodiment, the capsule endoscope enters the body by oral administration of a patient, and the capsule endoscope is pulled by the external traction assembly 100, so that the shooting position and shooting angle of the capsule endoscope are adjusted, and an operator can better know the internal condition of the patient. After the inspection is completed, the traction assembly 100 can be controlled to be separated from the capsule endoscope, thereby recovering the capsule endoscope and the traction assembly 100, respectively.

Specifically, the traction assembly 100 comprises a sleeve 101 for absorbing the capsule endoscope, a connecting seat 103 arranged in the sleeve 101 and electrically connected with the capsule endoscope, and a traction tube 105 connected with the sleeve 101 and communicated with the interior of the sleeve 101.

In this embodiment, the sleeve 101 is sleeved on the capsule endoscope, and is adsorbed on the capsule endoscope by the negative air pressure formed between the housing 10 and the sleeve 101, so that the capsule endoscope is displaced along with the sleeve 101.

The connecting seat 103 and the capsule endoscope are in matched butt joint by adopting a Pogo pin connector, and the connecting seat and the capsule endoscope can stably transmit current after being matched with each other, or transmit control signals, data signals and the like. Therefore, when the capsule endoscope is in butt joint with the connecting seat 103, current can be obtained from the outside through the traction assembly 100, and shooting signals or feedback control signals are transmitted to the outside through the traction assembly 100 in real time, so that a battery or a wireless transmission device is omitted from being arranged in the capsule endoscope, the internal space of the capsule endoscope is saved, and the volume of the capsule endoscope is reduced.

The traction tube 105 is fixedly connected with the sleeve 101, and when the capsule endoscope is positioned in a human body, the capsule endoscope can be adjusted by operating the traction tube 105 outside the body. The traction tube 105 introduces external air into the sleeve 101 to pull the capsule endoscope out of the sleeve 101. That is, when it is necessary to detach the capsule endoscope from the sleeve 101, the injected gas acts to increase the gas pressure between the sleeve 101 and the housing 10 by injecting gas into the sleeve 101, thereby releasing the capsule endoscope in the axial direction of the housing 10. The connecting wire connected with the connecting seat 103 is arranged in the traction tube 105 in a penetrating way and is finally connected with an external power supply device or a communication device.
