[0002] Fiber is increasingly used in the medical field. For example, optical fiber can be used in endoscopes, microscopes, and multimode / single-mode fiber sensors to help doctors make accurate diagnoses and operations.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] See also Figure 1 and Figure 3 As shown, Figure 1 This is a schematic diagram of the connection of the optical fiber treatment needle according to an embodiment of the present invention. Figure 3 The present invention provides a fiber optic therapeutic needle, comprising:

[0037] A structural needle 1, which is used to be inserted into the skin, comprises an opening 10 arranged on the side of the needle body of the structural needle;

[0038] An optical fiber needle 2, which is arranged inside the structural needle and connected to the outer side of the needle body of the structural needle through the opening 10, and the optical fiber of the optical fiber needle extends along the inner cavity of the structural needle;

[0039] An optical signal transceiver module 3, which is connected to the optical fiber needle 2 and is used to send a set optical signal to the optical fiber needle and receive an optical signal returned by the optical fiber needle;

[0040] An electrical signal transceiver module 4, which is connected to the structural needle and the optical fiber needle, and is used to send a set electrical signal to the structural needle 1 and / or the optical fiber needle 2;

[0041] A pressure acquisition module 5, which is connected to the optical signal transceiver module 4, and is used to determine the pressure value of the opening position of the structural needle inserted into the skin according to the transmitted optical signal and the received optical signal;

[0042] The signal analysis module 6 is connected to the pressure acquisition module 5 and is used to determine the strength of the transmitted electrical signal according to the pressure value, and to determine the adjustment amount of the electrical signal strength according to the pressure value.

[0043] It can be understood that the structural needle 1 of the present invention is used to be inserted into the skin. It can be a part of a medical device or can be used in conjunction with a medical device to enter the skin for operation. For example, it can be a treatment needle part of a laser treatment device or can be used in conjunction with a laser treatment needle. In addition, the number of openings 10 in the present invention is at least 1, and the number of openings can also be increased according to the specific detection accuracy. The more the number of openings, the more contact the optical fiber has with the contacted part, and the pressure value can be identified more accurately and sensitively.

[0044] The present invention uses the micro-pressure sensing technology of the fiber optic needle to obtain the pressure value and the change in the pressure value at the insertion position, and adjusts the intensity and duration of the physical therapy by the sensed pressure value or the change in the pressure value. It can accurately match the user for treatment, thereby improving the matching degree between the physical therapy laser and the user.

[0045] See also Figure 2 As shown, it is a schematic diagram of the sealing layer of the optical fiber therapeutic needle according to an embodiment of the present invention. The opening of the structural needle is provided with a sealing layer 20, and the outer surface of the sealing layer 20 is smoothly connected to the outer side surface of the structural needle 1.

[0046] It can be understood that the sealing layer 20 is used to protect the optical fiber structure. It can be set to be removable or non-removable, and it can be implemented in any way in the prior art. Optionally, the sealing layer uses a soluble substance that can be softened by body fluids, such as medical glucose crystals. It can also be set to a peelable medical sealing layer. However, it should be ensured that when the optical fiber is used to detect the pressure value, the opening is exposed so that the internal optical fiber is in contact with the detected position.

[0047] Please continue reading Figure 3 , which is a schematic diagram of the structure of the optical fiber treatment needle according to an embodiment of the present invention. Specifically, the optical fiber needle includes a plurality of optical fiber transmission parts for independently transmitting optical signals, and a sleeve arranged outside the optical fiber transmission part, wherein:

[0048] The sleeve, which is used to cover the optical fiber, includes an opening portion arranged corresponding to the opening 10 of the structural needle;

[0049] Each optical fiber transmission part does not contact each other to independently transmit the optical fiber signal.

[0050] In implementation, for example Figure 3 As shown, the optical fiber needle part inside the structural needle includes three independent optical fiber transmission parts 211, 212 and 213, which correspond to the sleeves 221, 222 and 223 respectively. It can be understood that the optical fiber transmission part 211 is connected to the opening of the structural needle, and therefore, an opening part is opened at the corresponding position on the corresponding sleeve 221 to expose the optical fiber transmission part 211.

[0051] It can be understood that the sleeve is used to block the interference of optical signals between the optical fiber transmission parts, and generally a material that can block photoelectric transmission is used to cover the outside of the optical fiber. Here, the form and material of the sleeve can be implemented in any way in the existing technology and will not be repeated.

[0052] For more details, please refer to Figure 3 As shown, the optical fiber transmission unit includes:

[0053] An optical fiber pressure transmission part 211 is disposed inside the sleeve and connected to the opening. The optical fiber pressure transmission part 211 is provided with an optical fiber extending along the inner cavity of the structural needle and covering the opening;

[0054] An optical fiber pressure control part 212, which is arranged inside the sleeve and is not connected to the opening, and the optical fiber pressure control part is provided with an optical fiber arranged in parallel with the optical fiber of the optical fiber pressure transmission part;

[0055] The optical fiber signal transmission part 213 is arranged inside the sleeve, and the optical fiber signal transmission part is provided with an optical fiber extending along the inner cavity of the structural needle.

[0056] In implementation, the optical fiber pressure transmission part is used to contact with an organ, tissue or body fluid after being inserted into the skin (when there is a sealing layer, after the sealing layer is removed or softened / liquefied), so as to sense the slight pressure change at the position of contact with the organ, tissue or body fluid through the slight light signal change of the optical signal in the optical fiber pressure transmission part. The optical fiber pressure control part is used as a control group for the light signal transmission change of the optical fiber pressure transmission part, and is combined with the optical fiber pressure transmission part to determine the pressure value or pressure change amount at the contact position.

[0057] Specifically, the size of the opening is determined according to the object characteristics of the pressure value to be obtained. In a specific implementation scenario, the object of the pressure value to be obtained is the fluid pressure characteristics, such as obtaining the pressure of blood or body fluids, the pressure opening must satisfy the body fluid overflowing to the opening so that the body fluid contacts the optical fiber, and the size of the opening is at least set to a quasi-circular shape with a short diameter of 0.6 mm; in another specific implementation scenario, the object of the pressure value to be obtained is the entity pressure characteristics, such as obtaining the pressure of an organ or tissue, the pressure opening must satisfy the entity contacts the optical fiber at the opening, and the size of the opening is at least the radius of its corresponding structural needle.

[0058] Specifically, the pressure acquisition module determines the pressure value of the opening position of the structural needle inserted into the skin according to the difference between the transmitted light signal and the received light signal.

[0059] It can be understood that optical fiber can transmit light, and pressure can cause the optical fiber to deform, thereby changing the transmission characteristics of light in the optical fiber. Therefore, in implementation, by analyzing the changes in the input and output of the optical signals of the optical fiber pressure control part and the optical fiber pressure transmission part, the pressure value currently sensed by the optical fiber pressure transmission part can be calculated, and this pressure value can reflect at least one sign of the contact position.

[0060] See also Figure 4 and Figure 5 As shown, in a specific embodiment, the optical fiber pressure transmission part and the optical fiber pressure control part are both attached to the inner wall of the structural needle. After contacting a specific contact object, the optical fiber of the optical fiber pressure transmission part at the opening position is deformed under pressure. Therefore, for a group of optical signals incident parallel to the inner wall of the structural needle, if it is set to be vertically reflected at the end, for the optical fiber of the optical fiber pressure control part without deformation, its optical signal intensity and optical signal distribution are uniform and theoretically the same as the incident optical signal. However, for the optical fiber pressure transmission part with contact deformation, its optical signal intensity and optical signal deviate from the inner wall of the structural needle at the deformation position, resulting in uneven distribution of optical signal intensity and being different from the incident optical signal. By judging the optical signal intensity and the position of the returned optical signal from the inner wall of the structural needle, the pressure value can be calculated. It can be understood that the larger the pressure value, the greater the deformation, the greater the loss of the parallel incident light transmitted by the optical fiber pressure transmission part, the lower the optical signal intensity, and the farther the returned optical signal is from the inner wall of the structural needle.

[0061] Specifically, the signal analysis module determines the strength of the initial electric signal sent by the electric signal transceiver module according to the pressure value obtained after being inserted into the skin for a preset time.

[0062] In implementation, the preset time is the time to ensure that the acquired data is stable and valid or the sealing layer has softened and the data is valid. It can be set according to the specific implementation scenario. Generally, the preset time is not less than 10 seconds after the structural needle is inserted into the skin.

[0063] In implementation, the intensity of the initial electrical signal corresponding to the obtained pressure value is set. For example, in a specific embodiment, the muscle tension at the contact position of the optical fiber needle is reflected by the pressure value. At this time, the muscle tension is a physical sign indicator. The muscle tension has a preset reasonable range in the medical field. When it exceeds the reasonable range, too low muscle tension will be manifested as a low pressure value detected, and too high muscle tension will be manifested as a high pressure value detected. Therefore, by detecting whether the pressure value exceeds the preset reasonable interval, it can be characterized whether the muscle tension is within a reasonable range. The specific reasonable range of muscle tension and the specific value of the preset reasonable interval corresponding to the pressure value can be determined by measuring a limited number of set positions, which will not be repeated here. In addition, in laser physiotherapy, muscle tension has a preset corresponding relationship with the laser intensity and frequency of laser treatment. At this time, since muscle tension and pressure value also have a one-to-one corresponding relationship, the intensity of the initial electrical signal sent by the electrical signal transceiver module (that is, the intensity of the laser) can be determined according to the pressure value.

[0064] In another specific embodiment, the blood pressure (blood pressure) at the contact position of the optical fiber needle is reflected by the pressure value. At this time, the blood pressure is a physical sign indicator. The blood pressure has a corresponding preset reasonable range in the medical field. When it exceeds the reasonable range, too low blood pressure will be manifested as a lower detected pressure value, and too high blood pressure will be manifested as a higher detected pressure value. Therefore, by detecting whether the pressure value exceeds the preset reasonable interval, it can be characterized whether the blood pressure is within a reasonable range. The specific reasonable range of blood pressure and the specific value of the preset reasonable interval corresponding to the pressure value can be determined by measuring a limited number of set positions, which will not be repeated here. Moreover, in laser physiotherapy, blood pressure has a preset corresponding relationship with the laser intensity and frequency of laser treatment. At this time, since the blood pressure and the pressure value also have a one-to-one corresponding relationship, the intensity of the initial electrical signal sent by the electrical signal transceiver module (that is, the intensity of the laser) can be determined according to the pressure value.

[0065] Specifically, the signal analysis module determines the adjustment amount of the strength of the electric signal sent by the electric signal transceiver module according to the pressure value obtained after the initial electric signal treatment.

[0066] In implementation, after the preset treatment time of laser treatment, the corresponding physical sign index and the medical indication of the physical sign index can be determined according to the pressure value at the same position obtained after the treatment, and the adjustment amount of the electric signal strength sent by the electric signal transceiver module is determined according to the diagnosis and treatment effect corresponding to the medical indication, wherein the diagnosis and treatment effect includes normal, improved and deteriorated, which can be judged according to the existing technology in the medical field. Here, the adjustment amount of the electric signal strength is determined only according to the judged diagnosis and treatment result, including:

[0067] If the treatment effect corresponding to the medical indication has shown to be normal, the electrical signal strength is adjusted to 0 and the treatment is terminated;

[0068] If the diagnosis and treatment effect corresponding to the medical indication shows improvement, the electrical signal strength of the current treatment is adjusted to be lower than the original electrical signal strength, and the amount is determined according to the corresponding relationship between the pressure value corresponding to the medical indication and the electrical signal strength;

[0069] If the diagnosis and treatment effect corresponding to the medical indication is shown to be worse, the electrical signal strength of the current treatment is adjusted to be higher than the original electrical signal strength, and the adjustment amount is determined according to the corresponding relationship between the pressure value corresponding to the medical indication and the electrical signal strength.

[0070] For example, the corresponding relationship between the pressure value F and the physical sign index ψ is obtained in advance, which can be expressed as F = f 1 (ψ), and in treatment, the physical sign index ψ has a corresponding relationship with the electrical signal strength Q, which can be expressed as Q = f 2 (ψ), therefore, the adjustment amount of the strength of the electrical signal sent by the electrical signal transceiver module can be determined based on the pressure value.

[0071] Specifically, the signal analysis module determines the strength of the transmitted electrical signal and the adjustment amount of the electrical signal strength according to the change in pressure value before and after historical treatment.

[0072] In implementation, the change in pressure value before and after historical treatment represents the change in physical sign indicators. If the expected level of treatment is not reached, it can guide the adjustment of the intensity of electrical signals during treatment to increase and improve the treatment effect; if the expected level of treatment is not reached, it can guide the adjustment of the intensity of electrical signals during treatment to remain unchanged or decrease and perform reasonable treatment; and the change in pressure value before and after historical treatment represents the change in physical sign indicators of the individual during the treatment process, and the change in physical sign indicators at the individual level is compared with the change in experience or preset physical sign indicators, and the strength of electrical signals for the individual during treatment is adjusted, which can accurately match the individual's treatment physical sign indicators and improve the treatment efficiency.

[0073] Specifically, it also includes an image acquisition module, which is connected to the optical fiber needle and is used to acquire image information inserted into the skin through the optical fiber needle.

[0074] In implementation, according to the specific medical scenario of the structural needle, the optical fiber signal transmission unit can obtain image information of the end of the structural needle to improve and expand the medical application scenarios of the optical fiber, obtain the position of the structural needle, and guide the movement direction and position of the structural needle.

[0075] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
