Description

Technical Field

[0001] The present invention relates to the technical field of data cables for medical operations, and particularly to a medical anti-break data cable and its anti-break production process. Background Art

[0002] Modern medical operations generally use operating instruments such as laparoscopes or thoracoscopes to assist in the operation. The information acquisition components of such instruments are connected to the end of the wire and extend into the body. During the operation, the information acquisition components need to move frequently for a long time. Therefore, it is necessary to ensure that their connection with the wire is always stable. At present, the upper limit of the number of swing times of the data cable used on medical operation instruments is generally 1000 times. In some complex operations, in order to ensure the normal progress of the operation, it is often necessary to prepare multiple operating instruments in advance. Summary of the Invention

[0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a medical anti-break data cable and its production process. Two bulletproof wires are added inside the cable and twisted together with the signal wire and the ground wire. One end of the two bulletproof wires and the ground wire are all fixed on the P1-end clamp, so that the P1-end clamp can keep the cable tightened for a long time, ensuring that the signal wire and the ground wire inside the cable can maintain a stable connection and electrical stability with the housing installed on the P1-end clamp and the operating instrument thereon for a long time, avoiding or reducing phenomena such as loosening and breaking of the cable after frequent swinging with the P1-end clamp and the operating instrument, and ensuring that the operating instrument can maintain stable and normal signal transmission for a long time, having a significant anti-break and anti-loosening effect.

[0004] To solve the above technical problems, a technical solution adopted by the present invention is as follows:

[0005] A medical anti-break data cable, including a cable, P1-end clamp and P2-end clamp are respectively arranged at both ends of the cable, the cable passes through the two clamps and extends to the outside thereof, and a housing for fixing an operating instrument is arranged on the periphery and / or end of the P1-end clamp; wherein:

[0006] The cable sequentially includes an outer sheath, an inner sheath, a braided tape, and a wrap from outside to inside. Twisted wires are arranged inside the wrap, and the twisted wires are twisted by more than two signal wires, one ground wire and two bulletproof wires. The ground wire and each signal wire include an insulating sleeve and several wires from outside to inside; both ends of the two bulletproof wires are respectively detachably fixed on the P1-end clamp and the P2-end clamp, and one end of the ground wire is fixedly connected to the P1-end clamp;

[0007] The P1-end clamp is a metal ring and is close to the operating instrument. Its outer wall is a T-shaped structure, including a positioning part and a connecting part. The outer diameter of the positioning part is larger and it is detachably fixed on the outer sheath and / or inner sheath of the cable, and the connecting part extends towards the outside of the cable.

[0008] As a further elaboration of the above technical solution:

[0009] In the above technical solution, the concentricity between the outer sheath and the inner sheath is greater than or equal to 80%.

[0010] In the above technical solution, the braided tape is woven from a number of silver-plated copper wires, and the braiding coverage rate is greater than or equal to 90%.

[0011] In the above technical solution, each of the wires is a silver-plated copper wire.

[0012] A technical solution adopted by the present invention is as follows

[0013] An anti-fracture production process for a medical anti-fracture data cable, where the medical data cable is the medical anti-fracture data cable described in the previous technical solution, and its production process includes the following steps:

[0014] Step S1 - Cable stripping: Strip the outer sheath, inner sheath, braided tape and wrapping of the cable extending to the outside of the two clamps, expose the signal wire, ground wire and bulletproof wire, and strip the insulating sleeves at the ends of each of the signal wires and ground wires outside the P1-end clamp to expose the wires inside;

[0015] Step S2 - Fixing the ground wire: Bend the wire of the ground wire in the reverse direction and then weld and fix it on the connection part;

[0016] Step S3 - Fixing the bulletproof wire: Fix one end of each of the two bulletproof wires on the P2-end clamp part, and bend the other end in the reverse direction and then surround the connection part in different directions and tie them together or fix them on the connection part.

[0017] As a further elaboration of the above technical solution:

[0018] In the above technical solution, between step S1 and step S2, the following steps are also included in sequence:

[0019] Step S11 - Dipping in flux: Dip the ends of the wires on the signal wire and the ground wire into the flux liquid to coat with flux;

[0020] Step S12 - Tin plating: Dip the ends of the wires after step S11 into the tin liquid in the tin furnace for tin plating.

[0021] In the above technical solution, the wires are vertically immersed in the flux and the tin liquid, and the length of the wire coated with flux is less than or equal to the length of the wire coated with tin liquid.

[0037] As Figure 1-2As shown, a medical anti-break data cable includes a cable 10, with a P1-end clamp 20A and a P2-end clamp 20B respectively provided at both ends of the cable 10. The cable 10 passes through the two clamps and extends to the outside thereof. A housing 30 for fixing an operating instrument is provided on the periphery and / or end of the P1-end clamp 20A; wherein:

[0038] As Figure 3 As shown, the cable 10 sequentially includes an outer sheath 1, an inner sheath 2, a braided tape 3, and a wrap 4 from outside to inside. Stranded wires are provided inside the wrap 4. The stranded wires are stranded by more than two signal wires 5, a ground wire 6, and two bulletproof wires 7. The ground wire 6 and each signal wire 5 each include an insulating sleeve 8 and a plurality of wires 9 from outside to inside; both ends of the two bulletproof wires 7 are detachably fixed on the P1-end clamp 20A and the P2-end clamp 20B, and one end of the ground wire 6 is fixedly connected to the P1-end clamp 20A;

[0039] As Figure 2 As shown, the clamp 20 close to the operating instrument is a metal ring, and its outer wall is a T-shaped structure, including a positioning part 21 and a connecting part 22. The positioning part 21 has a larger outer diameter and is detachably fixed on the outer sheath 1 and / or the inner sheath 2 of the cable 10, and the connecting part 22 extends towards the outside of the cable 10.

[0040] In the present invention, by adding two bulletproof wires 7 inside the cable 10 and stranding them together with the signal wires 5 and the ground wire 6, the toughness of the cable 10 can be further enhanced, making it better meet the usage requirements; by fixing one end of the two bulletproof wires 7 and the ground wire 6 on the P1-end clamp, the stability of the connection between the P1-end clamp and the cable 10 can be enhanced, so that the P1-end clamp 20 can keep the cable 10 tightly tensioned for a long time, and ensure that the signal wires 5 and the ground wire 6 inside the cable 10 can maintain stable connection and electrical stability with the housing 30 and the operating instrument installed on the P1-end clamp 20A for a long time, avoiding or reducing phenomena such as loosening and breaking of the cable 10 after frequent swaying with the P1-end clamp 20 and the operating instrument, and ensuring that the operating instrument can maintain stable signal transmission for a long time. Through experimental verification, the cable of the present invention can maintain continuous swaying 7000 times without breaking and connection detachment. Compared with the current conventional upper limit of 1000 swaying times, the present invention has a significant anti-break and anti-loosening effect, and can ensure that the functional component can maintain normal signal transmission for a long time.

[0041] In order to ensure a relatively high relative position accuracy among the operating instrument at the end of the cable 10, the P1-end clamp 20A, and the core wires inside the cable 10, the concentricity of the outer sheath 1 and the inner sheath 2 is greater than or equal to 80%.

[0042] In order to ensure stable signal transmission of each core wire inside the cable 10, the braided tape 3 is woven from a plurality of silver-plated copper wires, and the braiding coverage rate is greater than or equal to 90%.

[0043] In this embodiment, each wire 9 is a silver-plated copper wire.

[0044] A technical solution adopted by the present invention is as follows:

[0045] As Figure 4 shown, for the anti-fracture production process of the medical anti-fracture data cable, the medical anti-fracture data cable is the medical anti-fracture data cable in the above embodiment, and its production process includes the following steps:

[0046] Step S1 - Strip the cable 10: Strip the outer sheath 1, inner sheath 2, braided tape 3, and wrapping 4 of the cable extending to the outside of the two clamps 20, expose the signal wire 5, ground wire 6, and bulletproof wire 7, and strip the insulating sleeve 8 at the end of each signal wire 5 and ground wire 6 outside the P1-end clamp 20A to expose the wire 9 inside;

[0047] Step S2 - Fix the ground wire 6: Bend the wire 9 of the ground wire 6 in the reverse direction and weld it to the connecting part 22 for fixation;

[0048] Step S3 - Fix the bulletproof wire: Fix one end of each of the two bulletproof wires 7 on the P2-end clamp 20B, and bend the other end in the reverse direction and surround it around the connecting part and tie it together in different directions or fix it on the connecting part.

[0049] Furthermore, as Figure 3-4 shown, between step S1 and step S2, it further sequentially includes:

[0050] Step S11 - Dip in flux: Dip the ends of the wires 9 on the signal wire 5 and the ground wire 6 into the flux liquid to coat with flux;

[0051] Step S12 - Tin plating: Dip the ends of the wires 9 after step S11 into the tin liquid in the tin furnace for tin plating.

[0052] In step S11 and step S12, the wire 9 is vertically dipped into the flux and the tin liquid, and the length of the wire 9 coated with flux is less than or equal to the length of the wire 9 coated with tin liquid. The temperature of the tin furnace is 330° - 350°, and the dipping time in the tin liquid is 1 - 2 seconds.

[0053] Furthermore, as Figure 3 、 5 shown, step S2 sequentially includes:

[0054] Step S21 - Pre-tin: Preheat the outer wall of the connecting part 22 near the ground wire 6 with a soldering iron and place solder wire in this area for pre-tinning;

[0055] Step S22 - Weld the ground wire: Place the tinned part of the ground wire 6 against the pre-tinned area M and heat it with a soldering iron to weld the ground wire 6 to the connecting part.

[0056] In steps S21 and S22, the temperature of the soldering iron is 370°-390°, and the preheating time of the connection part in step S21 is 1-3 seconds.

[0057] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
