Description

{Endoscope tube}

The present invention relates to an endoscope tube configured to mount a driving wire therein to adjust a photographing position of a camera.

BACKGROUND ART [0002] Endoscopes in the medical field can be checked by observing the inside of the human body (stomach, bronchus, esophagus, large intestine, small intestine, etc.) using a small camera without using a surgical procedure or autopsy, Current endoscopes are being extended to various industrial fields such as not only in the medical field but also in observing the inside of the pipe without disassembling the precision machine or observing the abnormality inside the pipe.

A typical endoscope apparatus has a shape in which a camera is mounted at the tip of a tube. Inside the tube, a wire for transmitting image data for transmitting the image captured by the camera and a power supply wire for supplying power to the camera do. In order to adjust the photographing angle of the camera, the driving wire may be mounted on the inner surface of the tube through a separate coupling means.

On the other hand, in the conventional endoscope apparatus, since the driving wire is mounted in the circular tube through the separate coupling means, the assembly is inconvenient and the number of operations is increased. In addition, since it is important to minimize the diameter of the tube because a part of the tube is directly inserted into the body of the examinee, there is a problem that the diameter of the tube is increased because the driving wire is mounted on the inner surface of the tube through separate coupling means.

An object of the present invention is to provide an endoscope tube having a minimized diameter by improving the structure so that a driving wire can be directly inserted into a joint body.

According to another aspect of the present invention, there is provided an endoscope tube having a camera for capturing an inside of a human body, the tube being wound in a spiral manner so that a plurality of joints are stacked; And a plurality of first guide groove portions formed in the same pattern on the outer circumferential surfaces of the odd-numbered joint portions.

According to the present invention, since the first and second guide groove portions are formed in the joint body and then the drive wires are respectively inserted into the first and second guide groove portions, a separate coupling means for fixing the drive wire is not required.

Therefore, the inner space is wider than the conventional endoscope tube, and the diameter of the endoscope tube can be minimized. That is, in the related art, since the driving wire is inserted into the tube and then the tube and the driving wire are coupled using separate coupling means, the space in the tube is narrowed to increase the diameter of the tube. It is possible to minimize the diameter of the endoscope tube. Accordingly, it is possible to minimize the pain of the examinees during the examination using the endoscope.

In addition, since the endoscope tube and the driving wire are assembled by inserting the driving wire into the first and second guide groove portions in the endoscope tube, there is an advantage that the number of the operation holes is reduced and assembly is easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing an endoscope tube according to an embodiment of the present invention, and FIG. 2 is an illustration showing an example in which a driving wire is attached to the endoscope tube shown in FIG.

1 and 2, the endoscope tube 100 includes a joint body 110, joints 111 and 112, and a first guide groove 111a. Here, the endoscope tube 100 is mounted on one end of a camera for photographing the inside of a human body, and is equipped with a driving wire 10 to adjust the photographing position of the camera.

The joint body 110 is inserted into the inside of the human body, and the band is wound in a spiral shape so that a plurality of joints 111 and 112 are stacked. In this way, the joint body 110 is formed so as to be spirally wound so that a hollow is formed therein. Accordingly, the hollow of the joint body 110 may include a video data transmission wire for transmitting video data of the camera, a power supply wire for supplying power to the camera, and the like.

On the other hand, the band may be any material that is harmless to the human body and has good restoring force, but is preferably formed of silicon or polyurethane material.

A plurality of first guide groove portions 111a may be provided and the outer circumferential surfaces of the odd-numbered joint portions 111 are formed in the same pattern. More specifically, the first guide groove portion 111a may be formed in a hemispherical shape bent to the inside of the odd-numbered joint portion 111, and a driving wire 10 for bending the joint body 110 may be inserted therein have.

As the driving wire 10 is inserted into the first guide groove portion 111a, the angle of the joint body 110 can be adjusted. For example, as shown in FIG. 2, when the driving wire 10 of one side is pulled out, the odd-numbered joint part 111 comes into contact with the even-numbered joint part 112 and is refracted. Accordingly, a desired portion can be photographed by adjusting the photographing angle of the camera mounted on one end of the joint body 110.

Fig. 3 is a view showing another embodiment of the endoscope tube 100 in Fig. In the present embodiment, the differences from the above-described embodiment will be mainly described.

As shown in FIG. 3, the endoscope tube 200 may further include a second guide groove 112a. A plurality of second guide groove portions 112a may be provided and may be formed in the same pattern on the outer circumferential surfaces of the even-numbered joint portions 112. Further, it can be arranged to be deviated from the plurality of first guide groove portions 111a. The second guide groove portion 112a is arranged to be shifted from the first guide groove portion 111a so that the driving wire 10 inserted into the first guide groove portion 111a is supported by the even numbered joint portion 112, It does not fall off.

The second guide groove 112a may be formed in a hemispherical shape such that the second guide groove 112a is curved toward the inside of the even-numbered joint 112 in the same manner as the first guide slot 111a. 10 may be inserted. The second guide groove 112a is disposed to be offset from the first guide groove 111a so that the driving wire 10 inserted into the second guide groove 112a is supported by the odd- It does not fall off.

As described above, since the second guide groove 112a is further formed on the outer circumferential surface of the even-numbered joint part 112, the space for inserting the driving wire 10 is increased, so that the photographing direction of the camera can be adjusted at various angles do.

Although there is no limitation on the positions and the number of the first and second guide groove portions 111a and 112a, the first guide groove portions 111a are formed as a pair and are arranged to face each other on the odd-numbered joint portions 111, It is preferable that the groove portions 112a are formed as a pair and are disposed facing each other in the even-numbered joint portion 112. [

Accordingly, the joint body 110 can be bent and moved in the vertical direction through the driving wire 10 inserted in the first guide groove portion 111a, and the driving wire inserted into the second guide groove portion 112a 10 to move the joint body 110 in the lateral direction. Therefore, the camera mounted on one end of the joint body 110 can also be moved in the up, down, left, and right directions, so that the inside of the human body can be more closely photographed.

The endoscope tube 100 has the first and second guide slots 111a and 112a in which the driving wire 10 is inserted into the joint body 110 so that the driving wire 10 is fixed No separate coupling means is required.

Therefore, the inner space is wider than the conventional endoscope tube, and the diameter of the endoscope tube 100 can be minimized. That is, in the related art, since the driving wire 10 is inserted into the tube and then the tube and the driving wire 10 are connected to each other by using a separate coupling means, the space in the tube is narrowed to increase the diameter of the tube. The diameter of the endoscope tube 100 can be minimized since no separate coupling means for fixing the driving wire 10 is required. Accordingly, it is possible to minimize the pain of the examinees during the examination using the endoscope.
