[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] As Figure 1 shown, the present utility model is an antibacterial optoelectronic composite cable for medical surgery, comprising:

[0026] The optoelectronic composite cable has an outer sheath 7, and there are at least two conductors 1 and tight-buffered optical fibers 3 inside the outer sheath 7. The tight-buffered optical fibers 3 are communication optical units;

[0027] Wherein, an insulator 2 is sleeved outside the conductor 1, and there is a water-blocking filling 4 between the insulator 2 and the tight-buffered optical fiber 3; the conductor 1 and the insulator 2 form an energy-supplying electrical unit.

[0028] An antibacterial optoelectronic composite cable for medical surgery, while avoiding the risk of electromagnetic interference brought by conventional electrical signal transmission by selecting an optoelectronic composite structure, scientifically selects the conductor structure, insulation and sheath materials to ensure their characteristics.

[0029] The main communication material inside the communication optical unit is G657 bend-resistant optical fiber. Compared with commonly used optical fibers such as G652 and G654, G657 optical fiber has better bend resistance. During the use of the composite cable, cable bending inevitably occurs, and the anti-microbend loss performance of the bend-resistant optical fiber can ensure the normal and stable optical communication.

[0030] When forming the cable structure, a structure is selected in which the communication optical unit is in the middle and the energy-supplying electrical unit is cabled around the periphery. This is mainly because the optical fiber is relatively fragile. With the energy-supplying electrical unit surrounding the communication optical unit structure, the energy-supplying electrical unit can become the physical protection layer of the optical fiber in terms of structure, avoiding mechanical forces such as impact, cutting, and extrusion on the optical unit due to external forces.

[0031] A water-blocking filling 5 is sleeved outside the water-blocking filling 4, and the inner cushion layer 5 serves as a buffer protection;

[0032] There is a non-metallic braid 6 between the inner cushion layer 5 and the outer sheath 7; among them, the communication optical unit, the energy-supplying electrical unit and the water-blocking filling 4 are combined with auxiliary materials to form a single core as a whole through the cabling process; the use of the non-metallic braid 6 outside the inner cushion layer 5 realizes the longitudinal tensile strength and transverse compressive strength of the cable, and the outer sheath 7 uses antibacterial material and provides external mechanical protection.

[0033] The inner cushion layer 5 is made of the same material as the optical fiber sheath of the communication optical unit, namely polyester TPU elastomer, which is different from the insulating material of the power supply unit, polytetrafluoroethylene (PTFE), to avoid adhesion caused by long-term contact of the same material. Moreover, the polyester TPU elastomer material has good compatibility with the polytetrafluoroethylene (PTFE) insulating material and will not cause chemical reactions on the contact surface. The polyester TPU elastomer itself has good antioxidant and wear resistance. The antioxidant property ensures the service life of the product, and the wear resistance enables the inner cushion layer 5 structure to withstand bending movement and even extrusion and friction of the non-metallic braid 6 under tension during the use of the cable, playing a role in protecting the inner layer 5 structure and maintaining the integrity of the inner cushion layer 5 itself.

[0034] The conductor 1 is a multi-strand bundle structure conductor, and the material is a metal wire strand, and the metal wire strand is a copper wire strand or a tinned copper wire strand.

[0035] The material of the insulation 2 is polytetrafluoroethylene (PTFE) insulation; the polytetrafluoroethylene (PTFE) insulation material can meet sufficient electrical insulation even in extremely thin cases, and the material itself is soft. Compared with other commonly used insulation materials, on the premise of further ensuring the soft characteristics of the cable, it can also indirectly reduce the overall outer diameter of the cable, make the bending radius of the composite cable smaller, and reduce the impact on the operation of the medical process as a whole.

[0036] The tight-buffered optical fiber 3 includes an optical fiber sheath 31 and an optical fiber 32, and the optical fiber sheath 31 is sleeved outside the optical fiber 32; among them, the material of the optical fiber 32 is a G657 bend-resistant optical fiber, and the optical fiber sheath 31 is made of a polyester-type TPU elastic material.

[0037] The material of the water-blocking filling 4 is made of water-blocking yarn.

[0038] The material of the inner cushion layer 5 is a polyester-type TPU elastomer sheath.

[0039] The non-metallic braid 6 is made of aramid material; the non-metallic braid 6 structure can provide excellent longitudinal tensile strength on the premise of not reducing the bending performance of the composite cable, indirectly protecting the central optical fiber from being affected by the longitudinal force and affecting the optical signal transmission. At the same time, it also provides a certain amount of lateral compressive force.

[0040] The outer sheath 7 is made of antibacterial polyether TPU elastomer material; the antibacterial polyether TPU elastomer material is selected for the outer sheath 7. Besides providing the basic mechanical protection ability of the cable sheath, its excellent bending performance also meets the requirements of the overall flexibility of the composite cable. Moreover, the antibacterial polyether TPU material can effectively serve as a barrier to block bacteria. Sweating, tissue fluid, etc. contaminated in the surgical environment can volatilize quickly, and antibacterial components such as metal ions precipitated can effectively inhibit the reproduction of bacteria, effectively reducing the risk of surgical infection. And after the operation, the surface of the composite cable is easy to be disinfected and cleaned with alcohol, and its material has good compatibility with common medical cleaning and disinfection materials such as alcohol, without side reactions.

[0041] Among them, the conductor 1 is a multi-strand stranded copper conductor with a cross-sectional area of 0.75 mm², the conductor material is copper wire, and it adopts a 7-core stranded structure; the insulation 2 is a polytetrafluoroethylene insulation with a nominal thickness of 0.5 mm; the tight-buffered optical fiber 3 is a G657 bend-resistant optical fiber with an extruded polyester-type TPU elastomer sheath, and the nominal overall outer diameter is 2.0 mm; the water-blocking filling 4 uses water-blocking yarn for filling and is located between 6-core insulated wire cores in the cable structure; the inner cushion layer 5 uses a polyester-type TPU elastomer sheath material with a nominal thickness of 1.0 mm; the non-metallic braid 6 uses aramid braid, uses aramid yarn with detx = 200, the number of single-direction braided strands is 8, and the total number of bi-directional aramid yarns is 16; the outer sheath 7 uses antibacterial polyether TPU elastomer material, and the nominal sheath thickness is 1.2 mm.

[0042] It can be understood that the above embodiments are only exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
