[0005] This application provides a medical wire, including: a conductor for transmitting electrical signals;

[0006] An isolation section is provided on the conductor to isolate the conductor from electrical signal leakage and electromagnetic interference.

[0007] A protective sleeve is fitted over the insulating portion and is intended to come into contact with the human body.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0035] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0036] like Figures 1-2 As shown, this embodiment provides a medical cable, which includes a conductor 110, an insulating portion 120, a sheath portion 130, and a developing layer 140. The conductor 110 is used for electrical signal transmission; the insulating portion 120 is disposed outside the conductor 110 to prevent electrical signal leakage and electromagnetic interference; the sheath portion 130 is sleeved on the insulating portion 120 for contact with the human body; the developing layer 140 is used for development during fluoroscopy, and the developing layer 140 is located between the sheath portion 130 and the insulating portion 120. That is, when working through the medical cable 100, the insulating portion 120 can prevent line leakage, and can also absorb or reflect external electromagnetic waves to avoid electromagnetic interference from strong interference devices monitoring the medical cable, reducing the risk of misdiagnosis; it can also limit the electromagnetic field generated by internal signals within the shielding range, reducing energy loss caused by signal radiation or interference to other devices. Furthermore, the presence of a contrast layer ensures that the medical ray can be observed dynamically under fluoroscopy equipment, facilitating precise positioning and real-time monitoring of its movement, thereby enabling accurate operation.

[0037] In some embodiments, the developing layer 140 is composed of either barium sulfate or iodide to ensure that the medical line 100 is clearly visible under fluoroscopy, facilitating precise operation by the doctor.

[0038] In some embodiments, the conductor 110 is made of a copper alloy to ensure sufficient tensile strength.

[0039] In some embodiments, the copper alloy may be one of copper-nickel alloy, copper-aluminum alloy, etc., so that its tensile strength is greater than 200 MPa.

[0040] like Figure 2 or Figure 3 As shown, in this embodiment, the isolation part 120 includes an insulating layer 121 and a shielding layer 122; the insulating layer 121 is sleeved on the conductor 110 to isolate electrical signals. The design of the insulating layer 121 prevents current outflow, ensuring normal detection and avoiding harm to the human body from current outflow. The design of the shielding layer 122 prevents interference of electromagnetic signals by absorbing or reflecting external electromagnetic waves.

[0041] like Figure 2 As shown, in some embodiments, the shielding layer 122 is disposed between the insulating layer 121 and the sheath portion 130, and the shielding layer 122 is used to shield electromagnetic interference and leakage of internal electromagnetic signals.

[0042] like Figure 3 As shown, in another embodiment, the shielding layer 122 is embedded within the insulating layer 121, meaning that the shielding layer 122 does not contact the conductor 110. The shielding layer 122 is used to shield electromagnetic interference and the leakage of internal electromagnetic signals.

[0043] In some embodiments, the shielding layer 122 is one of a tin-plated braided layer or a silver-plated braided layer;

[0044] In some embodiments, the shielding layer 122 is not limited to tin-plated braided layers or silver-plated braided layers. Through braiding and surface plating treatment, the shielding layer 122 can have a good shielding effect against high-frequency interference.

[0045] In this embodiment, the sheath portion 130 is biodegradable. By making the sheath portion 130 biodegradable, the problem of foreign matter retention caused by the outer components of the sheath portion 130 falling off during operation due to the movement of the medical thread 100 can be prevented.

[0046] In this embodiment, the material of the sheath portion 130 includes at least one of thermoplastic elastomer, polyglycerol sebacic acid elastomer, and polylactic acid. That is, by utilizing the biocompatibility and biodegradability of thermoplastic elastomer, polyglycerol sebacic acid elastomer, and polylactic acid, the problem of foreign matter retention is solved.

[0047] In some embodiments, the material of the sheath portion 130 includes thermoplastic elastomers and polyglycerol sebacate elastomers.

[0048] In some embodiments, the material of the sheath portion 130 includes thermoplastic elastomer and polylactic acid.

[0049] In some embodiments, the material of the sheath portion 130 includes thermoplastic elastomer, polyglycerol sebate elastomer, and polylactic acid.

[0050] like Figures 1-2 As shown, in this embodiment, the sheath portion 130 includes an inner sheath 131 and an outer sheath 132; the inner sheath 131 is disposed outside the isolation portion 120; the outer sheath 132 is disposed outside the inner sheath 131, and the inner sheath 131 and the outer sheath 132 can be separated or installed. Since the absorbable medical suture 100 is expensive, and to prevent damage to the outer side of the absorbable medical suture 100, it needs to be replaced with a new suture 100 after a certain number of uses, which would increase medical costs. However, by using the arrangement of the inner sheath 131 and the outer sheath 132, and by allowing the inner sheath 131 and the outer sheath 132 to be separated or installed, it is easier to replace the outer sheath 132, thus reducing the overall cost of replacing the medical suture 100.

[0051] like Figure 2 or Figure 3 As shown, in this embodiment, there is a gap between the outer sheath 132 and the inner sheath 131, and the difference between the inner edge diameter of the outer sheath 132 and the outer edge diameter of the inner sheath 131 is 0.2-0.3 mm.

[0052] In some embodiments, the difference between the inner diameter of the outer sheath 132 and the outer diameter of the inner sheath 131 is 0.2 mm and 0.3 mm, respectively. When the diameter difference is 0.2 mm, it is convenient to remove the outer sheath 132 and can also prevent the inner sheath 131 and the outer sheath 132 from shifting by a large distance, which ensures the stability of the medical thread 100 during operation.

[0053] In this embodiment, the thickness of the outer sheath 132 is 0.1-0.3 mm.

[0054] In some embodiments, the thickness of the outer sheath 132 is 0.1mm, 0.2mm, or 0.3mm. A thickness of 0.2mm is considered optimal. This ensures sufficient usability for the intended lifespan while preventing wrinkles due to excessive thinness and bending difficulties due to excessive thickness.

[0055] like Figure 1As shown, in this embodiment, the connector 150 includes a first connector 151 and a second connector 152. The first connector 151 is disposed at both ends of the inner sleeve 131. When the outer sleeve 132 is fitted onto the inner sleeve 131, the second connector 152 moves closer to the first connector 151, causing the end of the outer sleeve 132 to press between the first connector 151 and the second connector 152. That is, when the outer sleeve 132 needs to be installed, the second connector 152 is separated from the first connector 151, allowing the outer sleeve 132 to move to the outside of the inner sleeve 131 from one side. When the outer sleeve 132 completely covers the inner sleeve 131, simply installing the second connector 152 onto the first connector 151 will press the end of the outer sleeve 132 between the first connector 151 and the second connector 152, preventing the inner sleeve 131 and the outer sleeve 132 from separating. When it is necessary to remove the outer sheath 132, the second connector 152 is separated from the first connector 151, and the outer sheath 132 is moved out of the inner sheath 131 from one side, thus completing the separation of the inner sheath 131 and the outer sheath 132.

[0056] like Figure 1 In some embodiments, the first connector 151 is provided with an external thread, and the second connector 152 is provided with an internal thread, and the first connector 151 and the second connector 152 are connected by threads.

[0057] like Figure 2 or Figure 3 As shown, in this embodiment, a sealing element 160 is also included; the sealing element 160 is used to seal the inner sheath 131 and the outer sheath 132 at the connector 150. When the outer sheath 132 is installed with the inner sheath 131 via the connector 150, the sealing element 160 prevents liquid leakage between the ends of the inner sheath 131 and the outer sheath 132 during use.

[0058] The seal 160 includes a sealing ring; the sealing ring is fitted onto the first connector 151, and the outer sheath 132 is located between the second connector 152 and the sealing ring. By placing the seal 160 on the side of the outer sheath 132 closer to the inner sheath 131, a better sealing effect is formed between the inner sheath 131 and the outer sheath 132.

[0059] In summary, this utility model provides a medical line that absorbs or reflects external electromagnetic waves through an isolation section, avoiding electromagnetic interference from strong interference devices and reducing the risk of misdiagnosis. It can also limit the electromagnetic field generated by internal signals within the shielding range, reducing energy loss caused by signal radiation or interference to other devices. Furthermore, the addition of a contrast layer facilitates precise operation.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
