Description

Technical Field

[0001] This utility model relates to the technical field of detection head frame components, and in particular to a TCD detection head frame that can record and position data. Background Technology

[0002] In the field of medical diagnostics, transcranial Doppler ultrasound (TCD) is a commonly used non-invasive examination method, mainly used to assess cerebral hemodynamics, particularly monitoring cerebral blood flow velocity and spectral characteristics, which is of great significance for diagnosing cerebrovascular diseases. However, traditional TCD examinations suffer from inaccurate localization and poor repeatability, primarily due to the difficulty in precisely controlling and fixing the probe position.

[0003] The traditional method involves the user first using an ultrasound probe to make preliminary, approximate markings on the patient's head surface to determine the location of the blood flow signal to be monitored. The user then adjusts and secures the headframe assembly based on this initial marking to maintain probe stability during the examination. However, in practice, once the headframe assembly is secured, if the user repositions the ultrasound probe to the initially marked location, even slight changes in the probe's angle or tilt often result in inaccurate location of the original blood flow signal. In this case, the user needs to fine-tune the probe's position horizontally and vertically to reposition it to the correct blood flow signal. This fine-tuning process is not only time-consuming and labor-intensive but also lacks a clear adjustment range and precision, leading to inconvenience and poor repeatability. Utility Model Content

[0004] The purpose of this invention is to disclose a TCD detection head frame assembly for recording positioning. This solves the problems of inconvenient operation and poor repeatability.

[0005] To achieve the above objectives, this utility model discloses a TCD detection headframe capable of recording and positioning, comprising: a headframe assembly, the headframe assembly including a head depth adjustment assembly, a head circumference adjustment assembly, and an assembly frame connected to both; an adjustment mechanism, the adjustment mechanism including a horizontal adjustment unit and a vertical adjustment unit, the horizontal adjustment unit being mounted on the assembly frame, and the vertical adjustment unit being mounted on the horizontal adjustment unit; a probe device, the probe device being rotatably connected to the vertical adjustment unit; and an adjustment assembly, the adjustment assembly including a first adjustment member and a second adjustment member coaxially arranged, the first adjustment member being drivenly connected to the horizontal adjustment unit for adjusting the horizontal position of the probe device relative to the headframe assembly, and the second adjustment member being drivenly connected to the vertical adjustment unit for adjusting the vertical position of the probe device relative to the headframe assembly.

[0006] By adopting the above scheme, the head frame assembly can be flexibly adjusted according to the different depths and circumferences of the patient's head to adapt to different head shapes and sizes, providing a basic support for the subsequent precise positioning of the probe. The horizontal and vertical adjustment units allow the probe to be adjusted independently yet collaboratively in the horizontal and vertical directions, enabling more precise control of the probe's position. The probe device is rotatably connected to the vertical adjustment unit, allowing the probe to move not only horizontally and vertically but also to rotate at a certain angle to adapt to the blood flow signal detection needs of different locations and angles, increasing the flexibility of the detection. Due to the precision of the adjustment mechanism and the controllability of the adjustment components, the accuracy of probe positioning can be ensured. When a re-detection is required, simply control the first and second adjustment components through the adjustment assembly to readjust the probe to the corresponding position according to the previously recorded parameters. This allows for quick and accurate retrieval of the original blood flow signal, eliminating the need for tedious fine-tuning processes required by traditional methods, greatly improving the convenience and repeatability of the operation.

[0007] Furthermore, the horizontal adjustment unit includes: a base, which is fixedly connected to the assembly frame, and the base is provided with a horizontal sliding groove in the horizontal direction. A first driving tooth is provided in the horizontal sliding groove, and the first driving tooth is drivenly connected to the first adjusting component; and a horizontal slider, which is slidably disposed in the horizontal sliding groove and is provided with a pivot hole for the adjusting component to pass through.

[0008] By adopting the above scheme, the presence of the first driving tooth makes the movement of the horizontal slider quantifiable. Operators can accurately calculate the movement distance of the horizontal slider based on the tooth pitch of the first driving tooth and the rotation of the first adjusting component. This allows for more precise control of the probe position in actual operation, avoiding the blind adjustment and uncertainty caused by the lack of a clear adjustment range in traditional methods, and enhancing the controllability of the adjustment process.

[0009] Furthermore, the horizontal slide groove includes: a first slide groove, wherein the first driving tooth is disposed on one side edge of the first slide groove; and a second slide groove, wherein a limiting part is provided in the second slide groove, the limiting part being used to restrict the horizontal slider from disengaging from the second slide groove.

[0010] By adopting the above scheme, the first slide focuses on driving and guiding, while the second slide focuses on limiting and stabilizing, providing precise driving guidance for the horizontal movement of the slider. Even in the event of operational errors or unexpected situations, such as excessive adjustment force, the limiting part can ensure that the slider always runs stably within the slide, preventing the probe from shifting or being damaged due to the slider coming off, thus ensuring the safety and stability of the entire detection process.

[0011] Furthermore, the vertical adjustment unit includes: a longitudinal slide rail, which is fixed vertically to the horizontal slider; and a vertical slider, which is slidably disposed on the longitudinal slide rail. The vertical slider has a longitudinal adjustment hole, and a second driving tooth is disposed vertically within the longitudinal adjustment hole. The second driving tooth is drivenly connected to the second adjustment member.

[0012] By employing the above scheme, the second adjusting component can precisely control the vertical movement distance of the vertical sliding component through engagement with the second driving tooth. By precisely controlling the rotation angle or displacement of the second adjusting component, high-precision adjustment of the vertical sliding component's position can be achieved, enabling the probe to accurately reach the required height, capture clear cerebral blood flow signals, and improve the reliability of the detection results. The cooperative structure of the longitudinal slide rail and the vertical sliding component provides stable support for the probe, reducing swaying and shaking during vertical movement and ensuring probe stability during detection. A stable probe position helps obtain more accurate and stable cerebral blood flow signals, improving the consistency and reliability of the detection results. Because the vertical adjustment unit has precise adjustment and guiding functions, during multiple tests, the operator can quickly and accurately reposition the probe to the same height based on previous adjustment parameters, achieving excellent repeatability.

[0013] Furthermore, the vertical sliding member includes: an adjustment part, on which the longitudinal adjustment hole is assembled; an assembly part, on which the probe device is assembled; and a bending part, which is connected between the adjustment part and the assembly part, for bringing the probe closer to the center of the head frame assembly.

[0014] By adopting the above design, the bent portion brings the probe closer to the detection area on the patient's head, which helps optimize the signal transmission path and reduce signal attenuation and loss during transmission. This improves the strength and clarity of the detection signal, enabling doctors to more accurately analyze the cerebral hemodynamic state and provide a more reliable basis for the diagnosis of cerebrovascular diseases.

[0015] Furthermore, the first adjusting member includes a first driving part, a first transmission rod, and a first operating part, and the second adjusting member includes a second driving part and a second operating part. The second driving part and the second operating part are provided with axial through holes. The ends of the first transmission rod are respectively connected to the first driving part and the second operating part, and the first transmission rod passes through the through holes.

[0016] By adopting the above solution, and inserting the first transmission rod through the perforation, the layout of each component is more rational and orderly. The components inside the adjustment unit are arranged more compactly, reducing unnecessary gaps and redundant structures, and improving space utilization. This compact layout also helps to reduce the weight of the headframe assembly, alleviating patient discomfort when wearing it. It also reduces the number of components required to achieve horizontal and vertical adjustment functions. This not only reduces the manufacturing cost of the equipment but also simplifies the assembly process and improves production efficiency.

[0017] Furthermore, the first and second operating units are provided with rotation angle indicators.

[0018] By adopting the above scheme, operators can precisely rotate the first operating part to the corresponding angle according to the indicator, quickly and accurately positioning the probe to the ideal horizontal position, reducing time wastage and patient discomfort caused by repeated adjustments. In clinical practice, it is often necessary to perform multiple tests on the same patient to observe changes in their condition, or to perform the same tests on different patients for comparative analysis. The rotation angle indicator allows operators to accurately record the rotation angle of the first and second operating parts during each operation, ensuring consistency in probe position by adjusting to the same angle in subsequent tests.

[0019] Furthermore, the probe device includes: a probe body; a retaining ring, wherein a spherical groove is formed in the center of the retaining ring, the probe body is rotatably connected to the spherical groove, and adjusting arms for adjusting the diameter of the retaining ring are provided at both ends of the retaining ring; and a retaining ring adjusting assembly for adjusting the distance between the two adjusting arms.

[0020] By adopting the above scheme, during the testing process, doctors may need to quickly adjust the probe angle based on the real-time blood flow signals to obtain clearer and more accurate signals. The free-rotation design within the spherical groove allows the probe to quickly respond to the doctor's adjustment needs, promptly changing the detection direction and improving testing efficiency.

[0021] Furthermore, the retaining ring is provided with a direction parameter mark, and / or the probe body includes a spherical part and a detection part, the spherical part is rotatably connected to the spherical groove, and the spherical part is provided with an arc surface scale.

[0022] By adopting the above scheme, the orientation parameter marker provides a clear positioning reference for the probe. When detecting the middle cerebral artery, operators can fix the probe at a specific angle according to the parameter marker. In cross-hospital or cross-regional clinical studies, the orientation parameter marker can standardize the adjustment criteria of different operators, making the test results more comparable and providing a reliable basis for large-scale data analysis. The arc-shaped scale can intuitively display the three-dimensional rotation angle of the probe within the spherical groove. Combined with the orientation parameter marker, when detecting complex cerebral vascular structures, operators can precisely adjust the probe's rotation and pitch angles through the scale to achieve multi-angle signal acquisition. The arc-shaped scale can record the angle change in real time, facilitating subsequent reproduction or analysis of the impact of angle changes on the signal.

[0023] Furthermore, the assembly frame is provided with a knob for adjusting the head circumference adjustment component, and the knob is provided with a rotation scale for adjusting the length of the head circumference adjustment component.

[0024] By adopting the above solution, adjusting the tightness of the knob is more convenient. The knob with a rotary scale allows doctors to directly rotate it to the corresponding mark based on the patient's head circumference, quickly completing the adjustment of the head frame component. Doctors can complete the head circumference adjustment within 10-15 seconds, saving valuable diagnostic and treatment time for patients.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. By adapting the depth and circumference of the patient's head to the head depth and circumference respectively through the head depth adjustment component and the head circumference adjustment component, combined with the horizontal adjustment unit and the vertical adjustment unit, the probe can be precisely adjusted independently and collaboratively in the horizontal and vertical directions, as well as the rotation function of the probe device, so as to achieve precise positioning of the probe in three-dimensional space.

[0027] 2. Existing adjustments, which involve manually loosening bolts to slide the fine-tuning probe, are susceptible to variations in adjustment results due to operator experience and fatigue. Utilizing a precise rotation adjustment assembly eliminates human error, ensuring consistent results for different operators and improving operational standardization.

[0028] 3. When repeated testing is required, the first and second adjustment components can be controlled by the operation unit to quickly and accurately restore the probe to the previously recorded parameter position, ensuring that the relative position of the probe and the target blood vessel is consistent each time, reducing blood flow signal acquisition errors caused by probe position deviation, and improving the accuracy and reliability of the test results;

[0029] 4. Accurate and stable blood flow signal acquisition provides a reliable basis for the diagnosis of cerebrovascular diseases. For example, in diagnosing diseases such as cerebral artery stenosis, occlusion, and cerebral vascular malformations, precise probe positioning helps to capture subtle hemodynamic changes, improve the early diagnosis rate, and give patients the best opportunity for treatment.

[0042] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0043] See Embodiment 1 of this utility model. Figures 1 to 5 As shown, a TCD detection head frame with recording and positioning capabilities is provided, including a head frame assembly 1, an adjustment mechanism 2, a probe device 3, and an adjustment component 4. The head frame assembly 1 includes a head depth adjustment component 11, a head circumference adjustment component 12, and an assembly frame 13 connected to both. Optionally, the head depth adjustment component is an arc-shaped support, connected to the assembly frame 13 via a slide rail, and can slide along the front-to-back direction of the head to adapt to different patients' skulls. It can also be adjusted using a backpack strap binding method. The head circumference adjustment component is a flexible strap, with both ends connected to the assembly frame 13 via a gear and rack mechanism. A knob 14 is provided in the middle of the strap, and the surface of the knob 14 is marked with a rotation scale 141. One rotation corresponds to a 5mm adjustment in the strap length, facilitating quick adaptation to the head circumference.

[0044] The adjustment mechanism 2 includes a horizontal adjustment unit 21 and a vertical adjustment unit 22. The horizontal adjustment unit 21 is mounted on the assembly frame 13, and the vertical adjustment unit 22 is mounted on the horizontal adjustment unit 21. The probe device 3 is rotatably connected to the vertical adjustment unit 22. The adjustment assembly 4 includes a first adjustment member 41 and a second adjustment member 42 coaxially arranged. The first adjustment member 41 is driven to the horizontal adjustment unit 21 and is used to adjust the horizontal position of the probe device 3 relative to the head frame assembly 1. The second adjustment member 42 is driven to the vertical adjustment unit 22 and is used to adjust the vertical position of the probe device 3 relative to the head frame assembly 1. The head frame assembly 1 can be flexibly adjusted according to the different depths and circumferences of the patient's head to adapt to the different head shapes and sizes of patients, providing basic support for subsequent precise probe positioning. The horizontal adjustment unit 21 and the vertical adjustment unit 22 enable the probe to be adjusted independently and collaboratively in the horizontal and vertical directions, allowing for more precise control of the probe's position. The probe device 3 is rotatably connected to the vertical adjustment unit 22, allowing the probe to move not only horizontally and vertically but also to rotate at a certain angle to adapt to the blood flow signal detection needs of different locations and angles, increasing the flexibility of the detection. Due to the precision of the adjustment mechanism 2 and the controllability of the adjustment component 4, the accuracy of probe positioning is ensured. When re-detection is required, simply control the first adjustment element 41 and the second adjustment element 42 through the adjustment component 4 to readjust the probe to the corresponding position according to the previously recorded parameters. This allows for quick and accurate retrieval of the original blood flow signal, eliminating the need for tedious fine-tuning processes required by traditional methods, greatly improving the convenience and repeatability of the operation.

[0045] Specifically, in some embodiments, the horizontal adjustment unit 21 includes a base 211, a horizontal slide groove 212, and a horizontal slider 213. The base 211 is fixedly connected to the assembly frame 13. Optionally, the base 211 is fixed to the fixing frame by bolts. The base 211 is provided with a horizontal slide groove 212 in the horizontal direction. Preferably, the horizontal slide groove 212 includes a first slide groove 2121 and a second slide groove 2122. A first drive tooth 2123 is provided on one side edge of the first slide groove 2121. A limiting part 2124 is provided in the second slide groove 2122 to limit the horizontal slider 213 from disengaging from the second slide groove 2122. The horizontal slider 213 slides within the horizontal slide groove 212. The presence of the first drive tooth 2123 makes the movement of the horizontal slider 213 quantifiable. The operator can accurately calculate the moving distance of the horizontal slider 213 based on the pitch of the first drive tooth 2123 and the rotation of the first adjusting member 41. This allows for more accurate control of the probe position in actual operation, avoiding the blindness and uncertainty of adjustment caused by the lack of a clear adjustment range in traditional methods, and enhancing the controllability of the adjustment process.

[0046] The first adjusting member 41 includes a first driving part 411, a first transmission rod 412, and a first operating part 413 coaxially arranged, used to drive the horizontal slider 213 to move horizontally. Specifically, the first driving part 411 meshes with the first driving gear 2123. The second adjusting member 42 includes a second driving part 421 and a second operating part 422. The second driving part 421 is sleeved on the outside of the first transmission rod 412 and coaxially nested with the first transmission rod 412 through a through hole 423. Preferably, the first driving part 411 and the second driving part 421 are gears, and the first operating part 413 and the second operating part 422 are knobs 14. By passing the first transmission rod 412 through the through hole 423, the layout of each component is more reasonable and orderly. The components inside the adjusting unit are arranged more compactly, reducing unnecessary gaps and redundant structures, and improving space utilization. This compact layout also helps to reduce the weight of the head frame assembly 1 and reduce the discomfort of patients when wearing it. It reduces the number of components required to achieve horizontal and vertical adjustment functions. This not only reduces the manufacturing cost of the equipment, but also simplifies the assembly process and improves production efficiency.

[0047] It should be noted that the horizontal slider 213 is provided with a pivot hole 2131 for the adjustment component 4 to pass through. Specifically, the length of the pivot hole 2131 is consistent with the exposed length of the first transmission rod 412 between the first drive part 411 and the second drive part 421, and can ensure a stable connection between the pivot hole 2131 and the adjustment component 4 as a whole, avoiding loosening. Preferably, a bearing is provided between the pivot hole 2131 and the first transmission rod 412, and the three are tightly connected, which can ensure the smooth rotation of the first transmission rod 412 itself, and also ensure that it will not tilt or loosen.

[0048] In various embodiments, the first operating part 413 and the second operating part 422 are provided with rotation angle indicators 5. The operator can accurately rotate the first operating part 413 to the corresponding angle according to the indicators, and quickly and accurately position the probe to the ideal horizontal position, reducing the time wastage and patient discomfort caused by repeated adjustments.

[0049] In some embodiments, the vertical adjustment unit 22 includes a longitudinal slide rail 221 and a vertical slider 222. The longitudinal slide rail 221 is fixed vertically to the horizontal slider 213. Optionally, the longitudinal slide rail 221 may be fixed by screws, welding, or integrally. The vertical slider 222 slides on the longitudinal slide rail 221. Optionally, a sliding block 223 is fixed to the rear or side of the vertical slider 222. The sliding block 223 slides along the longitudinal slide rail 221. The vertical slider 222 has a longitudinal adjustment hole 2223. A second driving tooth 2224 is arranged vertically within the longitudinal adjustment hole 2223. The second driving tooth 2224 is drivenly connected to the second adjustment member 42, specifically, the second driving tooth 2224 meshes with the second driving part 421. This configuration allows the second adjustment member 42 to precisely control the vertical movement distance of the vertical slider 222 by meshing with the second driving tooth 2224. By precisely controlling the rotation angle or displacement of the second adjusting member 42, high-precision adjustment of the position of the vertical sliding member 222 can be achieved, enabling the probe to accurately reach the required height, capture clear cerebral blood flow signals, and improve the reliability of the detection results. The cooperative structure of the longitudinal slide rail 221 and the vertical sliding member 222 provides stable support for the probe, reducing swaying and shaking during vertical movement and ensuring the stability of the probe during the detection process. A stable probe position helps to obtain more accurate and stable cerebral blood flow signals, improving the consistency and reliability of the detection results. Because the vertical adjusting unit 22 has precise adjustment and guiding functions, during multiple detection processes, the operator can quickly and accurately reposition the probe to the same height position based on the previous adjustment parameters, achieving good repeatability.

[0050] In some embodiments, the vertical slider 222 includes an adjustment portion 2221, an assembly portion 2222, and a bending portion 2225. The longitudinal adjustment hole 2223 is assembled to the adjustment portion 2221, the probe device 3 is assembled to the assembly portion 2222, and the bending portion 2225 connects the adjustment portion 2221 and the assembly portion 2222, for bringing the probe closer to the center of the head frame assembly 1. The bending portion 2225 brings the probe closer to the detection area of ​​the patient's head, which helps optimize the signal transmission path and reduce signal attenuation and loss during transmission. This can improve the strength and clarity of the detection signal, enabling doctors to analyze the cerebral hemodynamic state more accurately and provide a more reliable basis for the diagnosis of cerebrovascular diseases.

[0051] In various embodiments, the probe device 3 includes a probe body 31, a retaining ring 32, and a retaining ring adjustment assembly 33. A spherical groove 321 is formed in the center of the retaining ring 32. The probe body 31 is rotatably connected within the spherical groove 321. Adjusting arms 322 for adjusting the diameter of the retaining ring 32 are provided at both ends of the retaining ring 32. The retaining ring adjustment assembly 33 is used to adjust the distance between the two adjusting arms 322. It should be noted that the retaining ring adjustment assembly 33 can be a screw, which can adjust the distance between the two adjusting arms 322. This design allows the doctor to quickly adjust the probe angle to obtain a clearer and more accurate signal during the detection process, based on the real-time blood flow signal. The free rotation design within the spherical groove 321 enables the probe to quickly respond to the doctor's adjustment needs, promptly change the detection direction, and improve detection efficiency.

[0052] In various embodiments, the retaining ring 32 is provided with a direction parameter mark 323, and / or the probe body 31 includes a spherical part 311 and a detection part 312. The spherical part 311 is rotatably connected to the spherical groove 321. The spherical part 311 is provided with an arc-shaped scale 3111, and the direction parameter mark 323 provides a clear positioning reference for the probe. When detecting the middle cerebral artery, the operator can fix the probe at a specific angle according to the parameter mark. In cross-hospital or cross-regional clinical studies, the direction parameter mark 323 can unify the adjustment standards of different operators, making the test results more comparable and providing a reliable basis for large-scale data analysis. The arc-shaped scale 3111 can intuitively display the three-dimensional rotation angle of the probe in the spherical groove 321. With the direction parameter mark 323, when detecting complex cerebral vascular structures, the operator can accurately adjust the rotation and pitch angles of the probe through the scale to achieve multi-angle signal acquisition. The arc-shaped scale 3111 can record the angle change in real time, which is convenient for subsequent reproduction or analysis of the impact of angle change on the signal.

[0053] The adjustment process of this utility model is as follows:

[0054] Rotate knob 14 to the scale corresponding to the patient's head circumference value to tighten the head circumference adjustment piece; push the head depth adjustment piece to the appropriate cranial depth position and lock it.

[0055] Coarse probe positioning: Manually place the probe device 3 roughly in the target blood vessel area, such as the temporal window, and fix the probe angle by adjusting the bolt using the retaining ring 32.

[0056] Fine-tuning: Horizontal adjustment: Rotate the first operating part 413, which drives the horizontal slider 213 to move via the first drive gear 2123. Each rotation (10°) corresponds to a horizontal displacement of 0.5mm. Vertical adjustment: Rotate the second operating part 422, which drives the vertical slider 222 to rise and fall via the second drive gear 2224. Each rotation corresponds to a vertical displacement of 0.3mm. Angle adjustment: Adjust the probe's pitch and rotation angles according to the arc scale 3111 and the direction parameter mark 323, such as: elevation angle 20°, azimuth angle 30°.

[0057] Parameter recording and reproduction: Record the rotation angle of the first operating unit 413, the rotation angle of the second operating unit 422, and the probe direction parameters. During re-testing, the probe position can be quickly reproduced by adjusting the recorded parameters, with an error of less than ±0.2mm.

[0058] It should be noted that the above-described adjustment fineness is only one embodiment, and it can be varied in other embodiments to adapt to actual scenarios.

[0059] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0060] 1. By adapting the depth and circumference of the patient's head to the head depth adjustment component 11 and the head circumference adjustment component 12 respectively, and by combining the horizontal adjustment unit 21 and the vertical adjustment unit 22 to make independent and coordinated precise adjustments to the probe in the horizontal and vertical directions, as well as the rotation function of the probe device 3, the probe can be accurately positioned in three-dimensional space.

[0061] 2. Existing adjustments, which involve manually loosening bolts to slide the fine-tuning probe, are susceptible to variations in adjustment results due to operator experience and fatigue. Using adjustment component 4 for precise rotational adjustment avoids human error, ensuring consistent results for different operators and improving operational standardization.

[0062] 3. When repeated testing is required, the first and second adjustment components 42 can be controlled by the operation unit to quickly and accurately restore the probe to the previously recorded parameter position, ensuring that the relative position of the probe and the target blood vessel is consistent each time, reducing blood flow signal acquisition errors caused by probe position deviation, and improving the accuracy and reliability of the test results.

[0063] 4. Accurate and stable blood flow signal acquisition provides a reliable basis for the diagnosis of cerebrovascular diseases. For example, in diagnosing diseases such as cerebral artery stenosis, occlusion, and cerebral vascular malformations, precise probe positioning helps to capture subtle hemodynamic changes, improve the early diagnosis rate, and give patients the best opportunity for treatment.
