Description

The electricity and data cable for a medical treatment

The present invention relates to a medical power and data cable, and more specifically, the medical power and data developed to prevent the disconnection from occurring inside the cable used for oral endoscopy, mainly in dentistry or otorhinolaryngology more well bent It's about cables.

In order to examine the oral cavity in the dentistry or otolaryngology, oral endoscopy apparatus for displaying and analyzing the image by inserting a photographing unit with an image sensor inside the oral cavity is widely used.

In the case of such oral endoscopes, unlike the endoscope does not have to pass through the complex organs, there is a difference in the connecting cable.

However, the cable must be very well bent so that it can be easily inserted where necessary, and disconnection should not occur inside even under various circumstances such as repeated bending.

In addition, it must be able to effectively block the noise generated in the bundle of wires for accurate image transmission.

However, conventionally, these basic conditions were not effectively satisfied.

The present invention was developed to solve the above problems, the object of which is to develop a medical power and data cable that can effectively block the noise generated with a characteristic that is well bent.

In addition, the present invention is to develop a medical power and data cable that is durable enough to cope with shear force and tensile force and can reduce the occurrence of disconnection inside.

The present invention was developed in order to achieve the above object, and two power cables for connecting a power source therein, and a medical power and data cable formed with a data cable for transmitting data and formed therein In;
The power cable is formed inside the core is twisted in a predetermined direction, the coating layer is formed on the outer surface thereof, and is formed at the inner center in the form of three twisted in a predetermined direction together with the reinforcing core wire made of Kevlar or PE;
A core is twisted in a predetermined direction to form a data cable around the power cable, and a coating layer is formed on an outer surface thereof to form a spiral wrapped in the same direction;
And a vinyl coating layer formed on the outer surface of the data cable, a net wire net surrounding the outer surface of the vinyl coating layer, and a sheath surrounding the net wire net.

As described above, the present invention has a configuration in which the inner cable is twisted twice to form a covering and also blocks noise, thereby effectively preventing noise from occurring while having a better bending characteristic, thereby photographing the oral endoscope and The effect is easy to analyze.

In addition, by forming a core wire made of Kevlar or PE therein, it is effectively prevented from breaking even in tension or disconnection of some cables, thereby improving durability.

Figure 1 is a perspective view of an embodiment of the present invention.

Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

1 is a perspective view according to an embodiment of the present invention, Figure 2 is a cross-sectional view according to an embodiment of the present invention, Figure 3 is a conceptual diagram showing a manufacturing step of the cable according to an embodiment of the present invention, therein A medical power and data cable (1) in which two power cables (11) for connecting a power source and a data cable (12) for transmitting data are formed and a sheath (13) is formed outside thereof;

The power cable 11 is formed in the inner center in the form of two twisted in a predetermined direction with each other;

A data cable 12 is formed spirally wrapped in the same direction around the power cable 11;

It is composed of a vinyl coating layer 14 formed on the outer surface of the data cable 12, a mesh wire net 15 surrounding the outer surface of the vinyl coating layer 14, and a sheath 13 wrapping the net wire mesh 15. A medical power and data cable is shown.

Basically, when the lines inside the outer sheath 13 are aligned in a line, attempting to bend to one side results in a different degree of bending.

That is, according to the degree of bending, the inner and outer sides have a difference in the radius of curvature of the curvature. In the case of the inner side, the compressive force is applied to the outer side, and the bending in various directions that are repeated may cause disconnection.

Therefore, the wires inside the sheath are twisted helically to one side, and forming a sheath becomes a flexible cable that maintains durability in bending and has excellent bending property.

To this end, the present application twists the internal power cable 11, rather than just twisting it once, so that it is located at the center, and the data cable 11 is wound around the medical cable 11 so as to be formed in a spiral shape. If applied, the operator will be able to be connected to where necessary by using the more easily bent properties.

In addition, the vinyl coating layer 14 and the mesh wire net 15 to block the generated noise, which is already known in the art it will be desirable to form essentially in medical use.

In addition, in the present invention, the two power cables 11 are provided with an embodiment characterized in that the three are twisted in a predetermined direction together with the reinforcement core 16 made of Kevlar or PE.

In addition, the power cable 11 and the data cable 12 is formed by twisting the core wires 111 and 121 having a diameter of about 0.03 mm in a predetermined direction, and covering layers 112 and 122 formed on the outer surface thereof. Examples are further presented.

In the above embodiment, if the entire cable is composed only of the power cable 11 and the data cable 12, there is a possibility of being vulnerable to the tensile force. It was made.

In addition, when the durability is expanded in the present application, it is easy to form the entire cable 1 thinner, so when forming each of the power cable 11 and the data cable 12, thinner core wires 111 and 121 are formed. It is preferable to manufacture by using.
