Description

Technical Field

[0001] This utility model relates to the field of data cable technology for medical surgery, and in particular to a medical anti-breakage data cable. Background Technology

[0002] Modern surgical procedures typically utilize instruments such as laparoscopes or thoracoscopes. The data acquisition components of these instruments are connected to the end of a cable and extend into the body. During surgery, these components require frequent and prolonged movements, necessitating a stable connection between them and the cable. Currently, the maximum number of swings allowed for data cables on surgical instruments is generally 1000. In complex surgeries, multiple instruments are often prepared in advance to ensure successful operation. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a medical anti-breakage data cable. Two bulletproof wires are added inside the cable, twisted together with the signal wire and grounding wire. One end of each bulletproof wire and the grounding wire are fixed to the P1 end clamp, allowing the P1 end clamp to maintain cable tension for extended periods. This ensures stable connection and electrical stability between the signal wire and grounding wire inside the cable and the housing and operating instruments mounted on the P1 end clamp. It avoids or reduces the possibility of loosening or breaking of the cable after frequent swaying, ensuring stable and normal signal transmission for the operating instruments over a long period, and has significant anti-breakage and anti-loosening effects.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A medical-grade anti-breakage data cable includes a cable with a P1 end clamp and a P2 end clamp at both ends. The cable passes through the two clamps and extends to their outer sides. The periphery and / or end of the P1 end clamp is provided with a housing for fixing operating instruments. Wherein:

[0006] The cable, from the outside to the inside, includes an outer sheath, an inner sheath, a braided strip, and a wrapping. The wrapping contains a twisted wire, which is composed of two or more signal wires, one grounding wire, and two bulletproof wires twisted together. The grounding wire and each of the signal wires include an insulating sleeve and several conductors from the outside to the inside. The two ends of the two bulletproof wires are detachably fixed to the P1 end clamp and the P2 end clamp, respectively. One end of the grounding wire is fixedly connected to the P1 end clamp.

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

[0008] As a further explanation 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 strip is woven from several silver-plated copper wires, and the braiding coverage is greater than or equal to 90%.

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

[0012] In the above technical solution, the ends of the two bulletproof wires are bent in opposite directions and then wrapped around the connecting part in different directions, and their ends are knotted together.

[0013] In the above technical solution, the ends of the two bulletproof wires in the same direction are bent in opposite directions and then fixed to the P1 end clamp or the P2 end clamp. The end of the positioning part and / or the outer wall of the connecting part are provided with positioning elements for fixing the bulletproof wires.

[0014] In the above technical solution, the positioning element is a cam and / or a slot.

[0015] In the above technical solution, one end of the grounding wire is bent in the opposite direction and then welded to the outer wall of the connection part.

[0016] In the above technical solution, the positioning part is further provided with a wave spring and a guide ring along the axial direction on the end face of the connecting part, and the guide ring is detachably fixed to the inner wall of the housing by a sealing element.

[0017] In the above technical solution, the wave spring is a ring structure and its end is a wave-shaped end.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: by adding two bulletproof wires inside the cable and twisting them together with the signal wire and grounding wire, the toughness of the cable can be further enhanced, making it better meet the needs of use; by fixing one end of the two bulletproof wires and the grounding wire to the P1 end clamp, the stability of the connection between the P1 end clamp and the cable can be enhanced, so that the P1 end clamp can keep the cable taut for a long time, ensuring that the signal wire and grounding wire inside the cable can maintain a stable connection and electrical stability with the housing installed on the P1 end clamp and the operating device on it for a long time, avoiding or reducing the phenomenon of loosening or breaking of the cable after frequent swinging, and ensuring that the operating device maintains stable and normal signal transmission for a long time.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figure 1-2 As shown, the medical anti-breakage data cable includes a cable 10. The cable 10 has a P1 end clamp 20A and a P2 end clamp 20B at both ends. The cable 10 passes through the two clamps and extends to their outer sides. The periphery and / or end of the P1 end clamp is provided with a housing 30 for fixing operating instruments; wherein:

[0030] like Figure 3As shown, the cable 10 includes, from the outside to the inside, an outer sheath 1, an inner sheath 2, a braided strap 3, and a wrapping 4. The wrapping 4 contains a twisted wire, which is made of two or more signal wires 5, a grounding wire 6, and two bulletproof wires 7 twisted together. The grounding wire 6 and each signal wire 5 include an insulating sleeve 8 and several conductors 9 from the outside to the inside. The two ends of the two bulletproof wires 7 are detachably fixed to the P1 end clamp 20A and the P2 end clamp 20B, respectively. One end of the grounding wire 6 is fixedly connected to the P1 end clamp.

[0031] like Figure 2 As shown, the P1 end clamp 20A is a metal ring located near the operating instrument. Its outer wall has a T-shaped structure, including a positioning part 21 and a connecting part 22. The positioning part 21 has a large outer diameter and is detachably fixed on the outer sheath 1 and / or inner sheath 2 of the cable 10. The connecting part 22 extends toward the outside of the cable 10.

[0032] This invention enhances the toughness of the cable 10 by adding two bulletproof wires 7 inside the cable 10, twisting them together with the signal wire 5 and the grounding wire 6, thus better meeting usage requirements. By fixing one end of the two bulletproof wires 7 and the grounding wire 6 to the P1 end clamp, the stability of the connection between the P1 end clamp and the cable 10 is strengthened. This allows the P1 end clamp 20 to maintain a high tension on the cable 10 for extended periods, ensuring a stable connection and electrical stability between the signal wire 5 and the grounding wire 6 inside the cable 10 and the housing 30 and its operating device mounted on the P1 end clamp 20A. This prevents or reduces the possibility of the cable 10 becoming loose or broken after frequent swinging, ensuring stable signal transmission from the operating device over a long period. Tests have verified that the cable of this invention can withstand 7000 consecutive swings without breakage or connection detachment. Compared to the current conventional limit of 1000 swings, this invention demonstrates significant anti-breakage and anti-loosening effects, ensuring that functional components maintain normal signal transmission over extended periods.

[0033] To ensure that the operating device at the end of the cable 10, the clamp 20 at the P1 end, and the core wire inside the cable 10 maintain a high relative positional accuracy, the concentricity of the outer sheath 1 and the inner sheath 2 is greater than or equal to 80%.

[0034] To ensure stable signal transmission of each core wire within the cable 10, the braided tape 3 is made of several silver-plated copper wires, and the braiding coverage is greater than or equal to 90%.

[0035] In this embodiment, each wire 9 is a silver-plated copper wire.

[0036] like Figure 4 As shown, in one embodiment of this utility model, the ends of the two bulletproof wires 7 are bent in opposite directions and then wrapped around the connecting part 22 in different directions, and their ends are knotted together.

[0037] In another embodiment of this utility model, the ends of the two bulletproof wires 7 are bent in opposite directions and fixed to the P1 end clamp 20A or the P2 end clamp 20B. The end of the positioning part 21 and / or the outer wall of the connecting part 22 are provided with positioning members 23 for fixing the bulletproof wires 7. The positioning members 23 are protrusions and / or grooves. In this embodiment, as... Figure 5 As shown, a slot is formed at the end of the positioning part 21.

[0038] like Figure 6 As shown, in one embodiment of this utility model, one end of the grounding wire 6 is bent in the opposite direction and then welded to the outer wall of the connecting part 22.

[0039] like Figure 7 As shown, in one embodiment of this utility model, a wave spring piece 24 and a guide ring 25 are sequentially arranged along the axial direction on the end face of the positioning part 21 facing the connecting part 22. The guide ring 25 is detachably fixed to the inner wall of the housing 30 by a sealing member 26. In this embodiment, the wave spring piece 24 has an annular structure and its end has a wave-shaped structure.

[0040] Understandably, the wave-shaped spring 24 with its wave structure can tightly press the P1 end clamp 20 of the conductive ring 25 against the P1 end clamp 2, and can reduce the axial pressure or tension of external forces through the housing 30 on the P1 end clamp 20, thereby reducing the pulling force of the P1 end clamp 20 on the grounding wire 6, the bulletproof wire 7, and the outer sheath of the cable 10 fixed thereon, and ensuring the stability of the connection between the P1 end clamp 20 and the cable 10. In this embodiment, the seal 26 is a resin sealing ring, and the housing 30 is an aluminum shell.

[0041] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
