Description

TECHNICAL FIELD

[0001] The utility model relates to medical detection equipment technical field, concretely relates to a cross laser head built in medical auxiliary equipment and the scoliosis appearance of application thereof BACKGROUND

[0002] Since scoliosis affects the body balance based on the two ends of the spinal symmetry axis, further analyzing this imbalance becomes particularly important. Specifically, scoliosis causes changes in the length and tension of the muscles and soft tissues on both sides of the torso. The muscles on one side become tight due to compression or stretching, while the muscles on the other side relax due to lack of sufficient stretching. This asymmetry of muscles and soft tissues manifests as a width difference on both sides of the torso, i.e., one side of the torso appears wider or narrower than the other side. In addition, scoliosis also causes the pelvis to tilt, which in turn makes one leg shorter in actual or functional length. This asymmetry further exacerbates the degree of scoliosis and affects the overall balance of the body. However, although the scoliosis instrument can be used to measure the angle of scoliosis, it cannot further quantitatively analyze the body imbalance based on the two ends of the spinal symmetry axis.

[0003] To solve this problem, the cross laser head is built-in installed in the scoliosis instrument. When it is necessary to assist in analyzing the body imbalance based on the two ends of the spinal symmetry axis, the cross laser head emits a cross infrared laser by orientation, making its vertical laser line align with the spine. Through the scale on the horizontal laser line, the body balance based on the two ends of the spinal symmetry axis can be accurately measured, and the width difference of asymmetry can be quantified.

[0004] However, when the cross laser head is built-in in the medical auxiliary equipment, the following problems may occur. Due to the small size of the laser head, the internal space is very limited, which directly leads to the prominent problem of heat dissipation. If the heat cannot be effectively dissipated, the brightness of the light-emitting diode will decrease rapidly, and in severe cases, it will cause the equipment to overheat and damage, thereby affecting its long-term stability and service life. Secondly, the positioning accuracy of the components is also a big challenge. The optical components inside the small laser head need to be strictly aligned, but due to the compact structure, small errors during assembly or external vibrations during use can cause misalignment of the optical components.

[0005] In addition, the problem of thermal expansion cannot be ignored. During the operation of the laser head, a certain amount of heat will be generated, and the thermal expansion of the material will cause the displacement of the internal components, thereby affecting the stability and accuracy. Mechanical stress is also an important factor, especially during assembly and use. If the stress distribution is uneven or exceeds the bearing range of the material, it will cause instability of the structure. Over time, the fatigue effect will cause permanent deformation or failure of the components, thereby affecting the overall performance of the equipment. Finally, during the installation of the laser head, it is also a challenge to ensure its stable alignment with the scoliosis instrument. Utility model content

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0033] In the description of the application, it should be noted that unless otherwise expressly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through intermediate medium, can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0034] A scoliometer is a medical device used to measure and assess the degree of scoliosis, a condition characterized by an abnormal curvature of the spine that causes the spine to curve sideways. This instrument can quantify the degree of curvature and angle of the spine, helping doctors to assess the degree of scoliosis and the treatment that may be required. It can detect by measuring the posture and curvature of the patient's spine and generate corresponding data for doctors to analyze and diagnose.

[0035] However, often due to the scoliosis will affect the body balance based on the two ends of the spine as the axis of symmetry, further analysis of this imbalance becomes particularly important. Specifically, scoliosis causes changes in the length and tension of the muscles and soft tissues on both sides of the torso. The muscles on one side become tight due to compression or stretching, while the muscles on the other side become loose due to lack of sufficient stretching. This asymmetry of muscles and soft tissues manifests as a width difference between the two sides of the torso, i.e. one side of the torso appears wider or narrower than the other side. In addition, scoliosis also causes pelvic tilt, which in turn makes one leg shorter in actual or functional length. This asymmetry further exacerbates the degree of scoliosis and affects the overall balance of the body. However, the scoliosis instrument can only be used to measure the angle of scoliosis, but cannot further quantitatively analyze the body imbalance based on the two ends of the spine as the axis of symmetry. For the quantitative analysis of this imbalance, especially the width difference caused by the torso and the length difference caused by the pelvic tilt, the existing scoliosis measuring instrument cannot provide a comprehensive solution. Therefore, the company proposes to use a cross laser head built-in installed in the scoliosis instrument. When auxiliary analysis of the body imbalance based on the two ends of the spine as the axis of symmetry is needed, the cross infrared laser is directed to emit, and the vertical laser line in the cross laser is aligned with the spine. By the scale on the horizontal laser line, the body balance based on the two ends of the spine as the axis of symmetry can be accurately measured, and the width difference of the asymmetry can be quantified. However, when the cross laser head is built-in, the scale asymmetry caused by the focal length difference and the difficulty of adjusting to absolute level during focusing will occur; at the same time, the volume of the laser head is small and the heat dissipation is poor, which will cause the internal temperature to be too high, thereby affecting the stability of the laser; during the use of the scoliosis instrument, the internal components of the laser head will also be displaced due to vibration or external force impact, affecting the measurement results; during the built-in installation of the laser head in the scoliosis instrument, it is difficult to accurately position the laser head to be horizontally aligned with the scoliosis instrument after being relatively stable, which affects the accurate measurement of scoliosis. Therefore, in order to solve the above problems, a cross laser head built-in in a medical auxiliary device is proposed.

[0036] The cross laser head built-in in a medical auxiliary device is described in detail below. Figures 1 to 6 The cross laser head built-in in a medical auxiliary device is described in detail below.

[0037] First, please refer to the accompanying drawings Figure 1 and the accompanying drawings Figure 2As shown, the utility model provides a kind of cross laser head embedded in medical auxiliary equipment, including laser main body 300, inner cover 700, cross scale piece 200 and lens 100.The first side 360 of laser main body 300 has scale piece inlay groove 302 for installing cross scale piece 200 and lens groove 301 for installing lens 100, the scale piece inlay groove 302 is inlayed connection with cross scale piece 200 by interference fit, so that cross scale piece 200 is fixed in the upper portion of laser main body 300.The lens 100 is fixed in the lens groove 301 above scale piece inlay groove 302 by clamping, to ensure the accurate alignment of its position and direction.The inner cover 700 is tightly combined with the inner wall of the laser main body 300 on the second side 370 of the laser main body 300 by interference fit.The inner cover 700 not only plays a fixing role, but also forms a sealed connection with the laser main body 300, prevents the interference of external environmental factors, and in the case of thermal expansion and contraction, the interference fit of the inner cover 700 can effectively compensate the change of position, to ensure the stability of internal structure.By interference fit and clamping structure at both ends, a completely closed hollow chamber is formed.The closed hollow chamber not only provides effective protection for internal components, avoids the interference of external environment on its work, but also ensures the stability and accuracy of laser beam before emission, so that the cross laser head can maintain high precision and high reliability in harsh medical equipment working environment.

[0038] Please refer to the accompanying Figure 3 As shown, in some embodiments of the utility model, the laser main body 300 is formed by the cylindrical structure that is enclosed by the first side 360 and the second side 370 and the outer wall extending from the first side 360 to the second side 370, which is designed as a hollow cylinder.In the hollow cylinder, two stepped shoulders are arranged to ensure the stable positioning and functionality of internal components.In detail, a spring positioning shoulder 305 and an inner cover limiting shoulder 307 are arranged in the hollow cylinder, the spring positioning shoulder 305 is arranged with a stepped shoulder close to the first side 360 of the laser main body 300.The spring positioning shoulder 305 limits the position of the spring 400, the circumferential hollow inner wall formed by the spring positioning shoulder 305 is equal to or less than the diameter of the spring 400, to ensure that the spring 400 does not displace longitudinally when stressed, thereby providing reliable limiting effect after the spring 400 is installed.The inner cover limiting shoulder 307 is arranged with a second stepped shoulder close to the second side 370 of the laser main body 300.The inner cover limiting shoulder 307 limits the installation depth of the inner cover 700 to prevent the inner cover 700 from being inserted too deeply to affect the overall space layout inside.The shoulder provides an accurate positioning reference for the inner cover 700, to ensure that the inner cover 700 can be stably installed in place and form a good sealing effect without interfering with the normal function of internal components.

[0039] With reference to the accompanying drawings Figure 3 In some embodiments of the present application, the hollow interior of the laser body 300 is provided with a plurality of functional grooves and mounting spaces from the first side 360 to the second side 370. First, a lens groove 301 is arranged near the first side 360 for positioning and mounting the optical lens 100 of the laser. Next to the lens groove 301, a scale sheet fitting groove 302 is arranged along the axial direction, which provides a reliable positioning reference for the scale sheet through interference fit, ensuring that the scale sheet remains stable and does not shift during operation. Further along the axial direction of the hollow structure, a mounting groove 306 is provided, which has a size and shape suitable for the diode steel sleeve 500 and the spring 400 to ensure stable fitting during installation. The top of the diode steel sleeve 500 is coaxially connected and fixed with the spring 400, and then the diode steel sleeve 500 is fixed to the top of the inner cover 700. The inner cover 700 is connected in the inner cover accommodating cavity 304 through interference fit, so that the diode steel sleeve 500 and the spring 400 can be stably fitted in the mounting groove 306. In fact, the mounting groove 306 is a concentric cylindrical cavity formed by the inner extension of the inner cover limiting shoulder 307 and the butt joint of the step edge of the spring positioning shoulder 305. This cavity has clear start and end boundaries, ensuring that the spring 400 and the diode steel sleeve 500 can be accurately positioned and fixed inside, ensuring the coaxiality and stability of the assembly during assembly. Finally, the inner cover accommodating cavity 304 is arranged near the second side 370, which provides an accurate mounting space for the inner cover 700 by size control, ensuring that the inner cover 700 can be effectively limited during installation and form a tight fit with the inner wall of the laser body 300. The layout of the entire structure from the first side 360 to the second side 370 fully considers the installation sequence and space requirements of each functional component, forming a highly integrated mechanical internal structure system that ensures the stability and functionality of the laser body 300 during use.

[0040] In some embodiments of the present application, the axial center position of the mounting groove 306 is arranged within ±10% of the midpoint of the axial total length of the laser body 300, and the axial total length of the mounting groove 306 is 40%-60% of the axial total length of the laser body 300, which ensures uniform stress distribution, ensuring that the overall structure can provide sufficient support effect while avoiding unnecessary stress concentration, thereby helping to improve the stability of the overall structure, avoiding alignment deviation caused by element displacement or loosening, and for the deformation process caused by thermal expansion and mechanical stress, the stress change at this position is relatively balanced, which will not cause displacement or deformation of the assembly due to unilateral stress, thereby affecting the stability of the laser output.

[0041] Because the cross laser head is designed to be built-in in other medical auxiliary equipment, such as scoliometer, but in the process of built-in assembly, there is a key problem: how to accurately position the cross laser head in the assembly process, so that it can maintain absolute level relative to the scoliometer when the device is used. This is crucial because the scoliometer built-in laser head solution to evaluate the balance symmetry depends on the precise alignment of the cross laser beam emitted by the laser head, that is, when evaluating and quantifying body balance and symmetry, the laser beam must maintain absolute level. However, the relative position between the laser head and the scoliometer is difficult to determine during assembly. The general design of the cross laser head lacks special design for assembly and positioning, making it difficult to ensure the level of the laser head in actual application, which leads to inaccurate measurement and affects the diagnosis effect. In order to solve this problem and improve the convenience and accuracy of assembly operation, please continue to refer to the attached Figure 3 A positioning plane 380 is provided on the laser body 300. The laser body 300 is a hollow cylinder composed of a large-diameter cylindrical outer wall and a small-diameter cylindrical outer wall, which are coaxially arranged. The large-diameter cylindrical outer wall extends from the first side 360 of the laser body 300, while the small-diameter cylindrical outer wall extends from the second side 370 of the laser body 300 to the first side 360, and the two outer walls together form a stepped hollow cylinder with different outer diameters at the intersection. The positioning plane 380 is a reference plane formed by flattening the large-diameter cylindrical outer wall of the first side 360 to remove part of the circumference. The positioning plane 380 provides a clear reference surface, so that the laser head can be easily and accurately aligned with the scoliometer during assembly. This ensures that the cross laser beam emitted by the laser head can always maintain absolute level relative to the device during use, thereby ensuring the accuracy and reliability of the scoliometer when detecting body imbalance. Meanwhile, the laser body 300 is also provided with a mounting and fixing groove 303, which realizes the relative stability of the two when the cross laser head is built-in in the scoliometer.

[0042] Please refer to the attached Figure 4In some embodiments of the present application, the inner cover 700 is a cylindrical flat cover, the size of which matches the inner wall below the inner cover limiting shoulder 307 of the second side 370 of the laser main body 300. Thus, the inner cover 700 can be stably embedded and tightly matched with the laser main body 300. A light-emitting diode 600 is arranged at the center of the upper part of the inner cover 700, and three pins 701 are arranged at the lower part of the inner cover 700, which are used to be inserted into the corresponding hole positions on the circuit board 800. Through these pins 701, the circuit board 800 can provide power supply for the light-emitting diode 600 and realize the control thereof. The circuit board 800 itself is also a flat cylindrical structure, and three through holes 801 corresponding to the three pins 701 of the inner cover 700 are arranged at the center position of the circuit board 800, which are used for the insertion and electrical connection of the pins 701. The front surface of the circuit board 800 is provided with a laser chip 802, and the back surface is provided with a resistor 803. The power line 804 is led out from the back surface of the circuit board 800 to provide power input for the entire circuit.

[0043] When the small cross laser head is built into a medical auxiliary device, many problems will exist. For example, the laser head is small in size and limited in internal space, and poor heat dissipation becomes a prominent problem. If the heat cannot be effectively dissipated, the brightness of the light-emitting diode 600 will rapidly decrease, and in severe cases, the device will be damaged due to overheating. Secondly, the positioning accuracy of the components also faces challenges. The optical components in the small laser head need to be kept in strict alignment, but due to the compact structure, small assembly errors or external vibrations will affect the positioning accuracy, thereby affecting the precision of the laser output. At the same time, the problem of thermal expansion cannot be ignored. The laser head will generate heat during operation, and the thermal expansion of the material will cause the displacement of the internal components, thereby affecting the stability and measurement accuracy of the device. In addition, mechanical stress will cause structural instability during assembly and use, especially after long-term use, the fatigue effect will cause permanent deformation or failure of the components. On this basis, the present application introduces the combined structure of the diode steel sleeve 500 and the spring 400, please continue to refer to the accompanying drawings Figure 4 As shown in the drawings, the diode steel sleeve 500 is a hollow cylindrical cover structure, the bottom of which is an open bottom for covering the light-emitting diode 600, and the top axis is provided with a light transmission hole 501 for the laser beam to emit. The top of the diode steel sleeve 500 is coaxially connected with the spring 400, and the inner diameter of the spring 400 is greater than the diameter of the light transmission hole 501, which ensures that the spring 400 can be precisely embedded on the top of the steel sleeve during installation. The edge of the top of the steel sleeve is used as a support surface for bearing the stress of the spring 400, so that the spring 400 can be stably positioned above the steel sleeve when stressed, thereby avoiding displacement or tilting. The axis of the spring 400 corresponds to the through hole 801 of the top of the steel sleeve, and after the laser beam passes through the through hole 801 of the top of the steel sleeve, it continues to pass through the axis of the spring 400, realizing the beam guidance and stable light path output.

[0044] When assembled, the three pins 701 of the inner cover 700 are inserted into the corresponding through holes 801 on the circuit board 800, ensuring electrical connection, while the light-emitting diode 600 is installed at the center of the top of the inner cover 700, ensuring its coaxial alignment with the inner cover 700, and the open bottom of the diode steel sleeve 500 covers the light-emitting diode 600, the light transmission hole 501 of the diode steel sleeve 500 is strictly coaxial with the optical axis of the light-emitting diode 600, and the diode steel sleeve 500 is connected to the inner cover 700 by embedding, realizing the coaxial connection of the diode steel sleeve 500 and the inner cover 700. Since the inner cover 700 and the laser main body 300 are coaxially assembled and connected, the overall coaxiality of the diode steel sleeve 500 and the laser main body 300 is ensured. Then the center hole of the spring 400 is aligned and connected to the light transmission hole 501 at the top of the steel sleeve 500 on the diode steel sleeve 500 to ensure stable transmission of the light beam. That is, the spring 400, the diode steel sleeve 500 and the laser main body 300 are coaxially arranged, ensuring that the laser beam can maintain precise optical path alignment when passing through each component, reducing scattering and deviation of the light beam during transmission, thereby improving the precision and stability of the laser output. In some embodiments of the present application, the diameters of the spring 400 and the diode steel sleeve 500 are exactly the same, thereby ensuring that the spring 400 uniformly exerts force on the diode steel sleeve 500, so that the diode remains stable during operation and will not displace or tilt due to uneven force. This is crucial for maintaining the mechanical stability of the laser and prolonging the service life of the light-emitting diode 600. The assembled inner cover 700 assembly is pushed into the inner cover receiving cavity 304 of the laser main body 300, ensuring the reliable positioning of the inner cover 700 in the receiving cavity. At this time, the diode steel sleeve 500 and the spring 400 together enter the assembly groove 306 of the laser main body 300, ensuring the close fit and stability of the entire structure. The spring 400 plays a role of buffering and absorbing stress in the entire structure, avoiding permanent deformation or failure due to mechanical fatigue after long-term use. The diode steel sleeve 500 not only acts as a heat dissipation component in the structure, but also provides support for the light-emitting diode 600, ensuring its stability during the entire service life. At the same time, when the assembly is heated and expands, the spring 400 provides the necessary elastic compensation to prevent internal components from displacing due to thermal expansion, ensuring the stability and measurement accuracy of the device; due to the elasticity of the spring 400, even if there is a slight dimensional error during assembly, the assembly can still be automatically adjusted to the correct position by the pressure of the spring 400. This structure, in a long-term working environment, as the laser head will undergo frequent thermal cycles and mechanical vibrations, the hardness of the diode steel sleeve 500 and the elasticity of the spring 400 work together to better resist the fatigue effects caused by these factors, thereby prolonging the service life of the laser head.

[0045] Please continue to refer to the attached Figure 5As shown, the cross scale sheet 200 is a flat disc shape as a whole, with a circular edge, and at least includes vertical and horizontal scale lines in the center of the disc, which form at least one cross pattern, with scale lines evenly distributed along each line. The light beam passing through it is modulated according to the shape of the scale line, so that the light beam of the light-emitting diode 600 originally a light spot forms a cross-shaped light beam with scale after passing through the scale sheet. It is worth mentioning that the cross scale sheet 200 is based on the cross shape, but can be extended to various forms of scale sheets according to different needs. For example, it can be a cross shape, a mesh shape, etc., which are all based on cross units. By replacing different scale sheets, the laser head can generate light beam patterns of corresponding shapes according to different application needs when in use. Whether it is a more complex cross shape or a more precise mesh scale, the flexibility of these design forms makes the device have more extensive applicability in different scenarios. Therefore, other graphical scale sheets based on the cross are also within the protection scope of the present application.

[0046] Please continue to refer to Figure 6 and Figure 7 As shown, a cross laser head built into a medical auxiliary device is assembled. In some embodiments of the present application, the medical auxiliary device is a scoliosis instrument, which includes a scoliosis measurement support 900 and a detachable inertial measurement device 1000, which is installed on the former. The scoliosis measurement support 900 is provided with a positioning mounting position 990 for placing the inertial measurement device 1000. In the present application, the inertial measurement device 1000 is mainly used to measure whether it is absolutely horizontal when holding the scoliosis instrument. The scoliosis measurement support 900 is composed of a bottom shell 910 and a face shell 920. The bottom shell 910 is provided with a clamping groove 911, and the face shell 920 is provided with a clamping part 921. The face shell 920 is connected with the clamping groove 911 through the clamping part 921, so that the face shell 920 is combined with the bottom shell 910, to ensure the close combination between the bottom shell 910 and the face shell 920, and form a closed scoliosis measurement support 900.

[0047] Please continue to refer to the attached Figure 7 and the attached Figure 8As shown, the face shell 920 is provided with a laser portion 930 and a support fixing column 922. The laser portion 930 includes the cross laser head 932 and the pressing block 931 mentioned above, which are built into the medical auxiliary device. In one or more embodiments, the pressing block 931 includes a support fixing body 93 and a support foot 94 connected to the bottom of the support fixing body 93. The support fixing body 93 is a cuboid structure, and a limiting hole 9312 for accommodating the cross laser head 932 is provided at the top center of the support fixing body 93. The size of the limiting hole 9312 matches that of the cross laser head, so as to ensure stable installation. An alignment surface 9316 is further provided in the limiting hole 9312, which cooperates with the positioning plane 380 of the laser main body 300 of the cross laser head 932, so as to realize positioning of the relative position. The support foot 94 is located at the bottom and is in contact with the bottom of the face shell 920 during installation, thereby providing additional support and maintaining the stability of the pressing block 931. Support fixing positions 9311 are provided at the edges of the support fixing body 93, which are used for fixed connection with the face shell 920, so as to form a steady state. Specifically, the support fixing positions 9311 are connected with the reserved support fixing columns 922 on the face shell 920 through screws, thereby forming a stable connection between the pressing block 931 and the face shell 920. Meanwhile, the two support fixing columns 922 and the support foot 94 are in three-point support with the bottom of the face shell 920, thereby providing more stable stability. In addition, a protrusion 9315 is provided inside the support foot 94 at the bottom of the pressing block 931, which is used for matching with the installation fixing groove 303 of the laser main body 300, so as to realize fixation in the axial direction. Specifically, the protrusion 9315 is an annular protrusion, and the inner and outer profiles thereof are adapted to the structure of the installation fixing groove 303 on the laser main body 300. The installation fixing groove 303 is a groove extending around the circumference of a cylinder, and the design of the circumferential surface makes it cooperate with the protrusion 9315. The geometric shape of the installation fixing groove 303 matches the shape of the protrusion 9315, so that the protrusion 9315 can be inserted into the installation fixing groove 303. By inserting the protrusion 9315 into the installation fixing groove 303 of the laser main body 300, an interlocking structure is formed between the cross laser head 932 and the pressing block 931, so as to be firmly fixed and stable.

[0048] The bottom shell 910 is a component of the spinal curvature measuring support 900, and the bottom shell 910 is provided with an outward emission hole 912. The outward emission hole 912 provides a channel for the cross laser head 932 in the laser portion 930 to emit laser. When the face shell 920 is combined with the bottom shell 910, the cross laser head 932 is coaxially corresponding to the outward emission hole 912, so that it can emit outward from the inside.

[0049] In use, the cross laser head 932 of the scoliosimeter is opened, and the laser is emitted through the outer hole 912. In order to ensure the accuracy of the measurement, the handheld scoliosimeter is kept in an absolute horizontal state by the inertial measurement device 1000. Next, the cross infrared laser is directed to emit and align with the measured person, and the vertical laser line is aligned with the spine. By the scale on the horizontal laser line, the balance condition of the two ends of the body based on the symmetrical axis of the spine can be accurately measured, and the width difference of the asymmetry can be quantified. Due to the difference in projection distance, the actual length represented by the scale will change, but the scales on both sides are still scaled proportionally. By comparing the scale numbers on both sides, the width difference of the asymmetry can be intuitively identified and measured. This process ensures the accuracy of the scoliosis detection and the quantifiable evaluation results.
