[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Refer to the instruction manual Figures 1-5 , the utility model provides a medical side-by-side cable, comprising a cable body 1 for medical equipment;

[0025] In order to facilitate the temperature monitoring of surgical instruments and ensure the accuracy of medical staff's operations, such as Figures 1-4As shown, the cable body 1 includes a thermocouple element 11 and a coaxial cable 12. The coaxial cable 12 includes a stranded conductor 121 made of 19 silver-plated copper wires stranded together. A first insulating layer 122 is provided outside the stranded conductor 121. A first shielding layer 123 is provided outside the first insulating layer 122. A protective layer 124 is provided outside the first shielding layer 123. The thermocouple element 11 includes a first conductor 111 and a second conductor 112. The first conductor 111 and the second conductor 112 are arranged side by side inside the protective layer 124. Second insulating layers 113 are provided outside both the first conductor 111 and the second conductor 112. A second shielding layer 114 is provided outside the second insulating layers 113. An inner protective layer 115 is provided outside the second shielding layer 114.

[0026] Specifically, the thermocouple element 11 is formed by the first conductor 111 and the second conductor 112, and then the temperature of the head of the surgical instrument is monitored thereby, enabling medical staff to accurately know the temperature change of the surgical instrument, so as to ensure the accuracy of the operation of the medical staff.

[0027] To ensure the use stability of the cable body, as Figures 2-4 shown, the first conductor 111 is made of copper wire, and the second conductor 112 is made of constantan wire. By using copper wire with excellent electrical conductivity, bend resistance and tensile strength to make the first conductor 111, and then using constantan wire with excellent electrical conductivity, thermal conductivity, mechanical properties and stable resistance characteristics to make the second conductor 112, the reliability and durability of the thermocouple element 11 can be ensured. The first insulating layer 122 is made of polytetrafluoroethylene material. The second insulating layer 113 and the inner protective layer 115 are both made of FEP material. By using EDP material with excellent heat resistance, chemical resistance and electrical insulation properties to make the second insulating layer 113 and the inner protective layer 115, the insulation effect and protection effect of the thermocouple element 11 can be ensured. By using polytetrafluoroethylene material with excellent insulation performance to make the first insulating layer 122, the coaxial cable 12 can exhibit stable electrical insulation characteristics within a large temperature and frequency range. The first shielding layer 123 is made of tinned copper wire, and the second shielding layer 114 is made of silver-plated copper wire. By using tinned copper wire and silver-plated copper wire with electrical conductivity, corrosion resistance and electrical signal shielding functions to make the first shielding layer 123 and the second shielding layer 114, the transmission stability of the thermocouple element 11 and the coaxial cable 12 can be ensured.

[0028] To facilitate the shielding and protection of the cable body, and at the same time improve the convenience of fixing the cable body, as Figure 1 and 5As shown, an elastic sleeve 2 capable of deformation is sleeved outside the cable main body 1. Through the deformable elastic sleeve 2, medical staff can sleeved the elastic sleeve 2 outside the cable main body 1, and shield and protect the cable main body 1 by means of the elastic sleeve 2, avoiding the situation that the coaxial cable 12 and the thermocouple element 11 inside the cable main body 1 are split due to accidental touch or collision, thereby ensuring the integrity of the cable main body 1. A hook 3 is installed on one side of the elastic sleeve 2. Through the connection between the hook 3 and the elastic sleeve 2, medical staff can fix the cable main body 1 in place by means of the hook 3, thereby avoiding the cable main body 1 from being scattered and affecting the operation convenience.

[0029] The stranded conductor 121 is made by stranding 19 silver-plated copper wires, so that the coaxial cable 12 can provide energy for the head of the medical surgical instrument. Then, the thermocouple element 11 is composed of a first conductor 111 made of copper wire and a second conductor 112 made of constantan wire. Thus, the temperature of the head of the medical surgical instrument can be monitored, enabling medical staff to accurately know the temperature change of the head of the medical surgical instrument, thereby improving the operation accuracy of medical staff. Arranging the thermocouple element 11 and the coaxial cable 12 side by side can save space and facilitate the operation of medical staff.
