Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and more specifically, to a bedside cranial ultrasound scanning system for newborns. Background Technology
[0002] The main purposes of neonatal cranial ultrasound examination include the diagnosis and follow-up of cerebral hemorrhage and hydrocephalus. A clear diagnosis and timely follow-up help in the effective treatment of the infant and avoid delays in treatment that could lead to serious adverse consequences. Neonates requiring bedside cranial ultrasound examinations include premature infants, low-birth-weight infants, or infants whose condition necessitates their presence in the intensive care unit. Currently, bedside cranial ultrasound examinations are performed collaboratively by an ultrasound physician and intensive care unit nurses. The nurse stabilizes the infant's head while the physician holds the probe at the anterior fontanelle for dynamic scanning. However, during the examination, nurses often struggle to control the pressure applied to the infant's head, leading to significant head movement and preventing the ultrasound probe from maintaining a proper fit at the anterior fontanelle, resulting in time-consuming examinations and poor image quality. Furthermore, variations in the skill level of ultrasound physicians and their inherent subjectivity can also lead to significant differences in image quality. Forcibly stabilizing the infant with external force can cause discomfort.
[0003] Therefore, there is an urgent need to provide a bedside cranial ultrasound scanning system for newborns to compensate for the shortcomings of existing technologies to some extent. Summary of the Invention
[0004] The purpose of this application is to provide a bedside cranial ultrasound scanning system for newborns, which to some extent solves the problems of poor examination timeliness, large differences in image quality, and poor patient comfort during the current newborn cranial ultrasound examination process, which requires operation by an ultrasound doctor and holding and fixing the child's head.

[0009] Furthermore, the adjustable section includes a positioning section and an adjustment section. The cross-sectional area of the positioning section is the same as that of the base section, such that the end of the positioning section abuts against the end of the base section. The adjustment section has the same size as the guide groove and is located within the guide groove. The mating recess is formed on the adjustment section.
[0010] The surrounding mechanism includes at least three arc-shaped adjustable supports, which are evenly distributed around the circumference of the headband mechanism. Each adjustable support includes a support section and a telescopic section. The support section is hollow, with one end connected to the headband mechanism. One end of the telescopic section is slidably connected to the support section and can retract or extend from the support section. The ends of the telescopic sections of the three adjustable supports that are furthest from the support section are located on the same horizontal plane, forming the positioning plane. The probe fixing device is connected to the end of the telescopic section.
[0011] Specifically, the adjustable support further includes an elastic element, a retractor, and a pull rope; the elastic element is disposed within the support section, with one end abutting against the bottom of the support section and the other end connected to the end of the telescopic section located within the support section; the retractor is located at the bottom of the support section; the pull rope is wound within the retractor, and one end of the pull rope is connected to the telescopic section.
[0012] Furthermore, at least the inner sides of the base segment and the adjustable segment are covered with a soft cladding layer.
[0013] The probe fixing device includes a cylinder and a clamping assembly. A positioning groove is formed in the cylinder.

[0015] Compared with existing technologies, the neonatal bedside cranial ultrasound scanning system provided by this invention has the following advantages: The present invention provides a neonatal bedside cranial ultrasound scanning system for scanning the cranium of newborns. It includes a head fixation device, a probe fixation device, and a scanning probe. The head fixation device forms a covering space, allowing the newborn's head to enter and the head fixation device to cover the newborn's head. The head fixation device also forms a positioning plane, one end of which is fixedly connected to the positioning plane. A clamping space is formed within the probe fixation device, into which the scanning probe extends, and the scanning end of the probe enters the covering space and contacts the newborn's anterior fontanelle.
[0016] Analysis shows that the neonatal bedside cranial ultrasound scanning system provided in this application provides a foundation for accommodating the newborn's head through the enclosing space formed by the head fixation device. In other words, when in use, the head fixation device is placed on the newborn's head. Since the head fixation device forms a positioning plane, the positioning plane provides a foundation for connecting the probe fixation device and the head fixation device.
[0017] Accordingly, since the probe fixing device provided in this application has a clamping space, it is possible to clamp the scanning probe and keep it in a position such that... Figure 1 The state shown allows the scanning tip of the scanning probe to enter the enclosed space and contact the newborn's anterior fontanelle.
[0018] It is understandable that, since the probe fixing device provided in this application can position the scanning probe, the scanning probe can be combined with the head fixing device. That is, during the examination, the head fixing device can be placed on the newborn's head first, then the scanning probe can be inserted into the formed clamping space, and finally the position of the scanning probe can be adjusted so that the scanning end contacts the newborn's anterior fontanelle, thus completing the preparation before the examination.
[0019] Once completed, because the head fixation device moves with the newborn's head, the scanning probe remains relatively fixed in position relative to the newborn's head even if the newborn's head moves, thus ensuring the examination effect. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0025] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0026] like Figures 1-3 As shown, the neonatal bedside cranial ultrasound scanning system provided in this application is used to scan the cranium of a newborn. It includes a head fixation device, a probe fixation device 3, and a scanning probe 4. The head fixation device forms a covering space, through which the newborn's head can enter, allowing the head fixation device to cover the newborn's head. The head fixation device also forms a positioning plane, one end of the probe fixation device 3 is fixedly connected to the positioning plane, and a clamping space is formed inside the probe fixation device 3. The scanning probe 4 extends into the clamping space, and the scanning end of the scanning probe 4 enters the covering space and contacts the newborn's anterior fontanelle.
[0027] Compared with existing technologies, the neonatal bedside cranial ultrasound scanning system provided by this invention has the following advantages: The neonatal bedside cranial ultrasound scanning system provided by the present invention provides a foundation for accommodating the newborn's head by forming a covered space through the head fixation device. In other words, when in use, the head fixation device is placed on the newborn's head. Since the head fixation device forms a positioning plane, the positioning plane can provide a foundation for connecting the probe fixation device 3 and the head fixation device.
[0028] Accordingly, since the probe fixing device 3 provided in this application has a clamping space, the scanning probe 4 can be clamped, keeping the probe in a position as described above. Figure 1 The state shown allows the scanning end of the scanning probe 4 to enter the enclosed space and contact the anterior fontanelle of the newborn.
[0029] It is understandable that, since the probe fixing device 3 provided in this application can position the scanning probe 4, the scanning probe 4 can be combined with the head fixing device. That is, during the examination, the head fixing device can be placed on the newborn's head first, then the scanning probe 4 can be inserted into the formed clamping space, and finally the position of the scanning probe 4 can be adjusted so that the scanning end contacts the newborn's anterior fontanelle to complete the preparation before the examination.
[0030] After completion, because the head fixation device always moves with the newborn's head, even if the newborn's head moves, the scanning probe 4 will always remain relatively fixed in position with the newborn's head, thus ensuring the examination effect.
[0031] After installation, the scanning probe 4 in this application corresponds to the anterior fontanelle of the newborn. Since the head fixing device can remain relatively stationary with the newborn's head after being worn, i.e., the aforementioned follow-up state, the scanning probe 4 can also remain relatively stationary with the anterior fontanelle, i.e., always aligned with the anterior fontanelle position for scanning, thereby ensuring scanning accuracy and avoiding the problem of image blurring caused by the newborn's head shaking.
[0032] It should be further explained here that the probe fixing device 3 in this application has a cylindrical structure, and multiple gripper structures can be evenly arranged on the circumference. The multiple gripper structures can include gripping claws, springs and positioning cylinders. The positioning cylinder has a hollow structure, and the spring is set inside the positioning cylinder. One end of the gripping claw has a claw part, and the other end is a rod part that extends into the positioning cylinder and is connected to the spring. The positioning cylinder extends radially along the probe fixing device 3. Therefore, under the action of the spring, the multiple gripping claws can move towards the center of the circle, thereby forming the above-mentioned clamping space. When the scanning probe 4 is inserted, it pushes the gripping claws to move away from the center of the circle. Under the action of the spring, the gripping claws will be pushed to abut against the outer wall of the scanning probe 4, thereby achieving the clamping of the scanning probe 4.
[0033] Of course, the neonatal bedside cranial ultrasound scanning system provided in this application also includes a scanning terminal, which can feed back the scanning status of the scanning probe 4 to the scanning terminal for display. Both the scanning terminal and the scanning probe 4 are performed using existing ultrasound scanning equipment, which will not be described in detail here.
[0034] It should be further noted that, in order to ensure the stability of wearing during the examination, the head fixation device provided in this application can also be equipped with an elastic chin strap, so that the wearing of the head fixation device can be more stable by using the chin strap, thereby ensuring the stability of the scanning process of the scanning probe 4.
[0035] Based on this, such as Figures 1-5 As shown, the head fixing device in this application includes a headband mechanism 1 and a surrounding mechanism 2. The headband mechanism 1 includes a base section 101, an adjustable section 102, and an adjustment component. Both the base section 101 and the adjustable section 102 have an arc-shaped structure, and the base section 101 and the adjustable section 102 are joined to form a circular positioning space. The adjustment component is installed in the base section 101, and the adjustment end of the adjustment component is connected to one end of the adjustable section 102, so that a part of the adjustable section 102 can enter or extend into the base section 101 to shrink or expand the diameter of the positioning space.
[0036] Since the head fixation device provided in this application needs to be worn on the head of a newborn, and different newborns have different head circumferences, this application makes the headband mechanism 1 a two-section structure and installs an adjustment component in the base section 101, so that the adjustment end of the adjustment component is connected to one end of the adjustable section 102. This allows the adjustable component to allow a portion of the adjustable section 102 to enter or extend out of the base section 101, thereby achieving adjustment of the diameter of the overall headband mechanism 1.
[0037] The adjustment component in this application may include an adjustment toothed roller and an adjustment motor. Accordingly, in this embodiment, the adjustable section 102 is an arc-shaped sheet structure, and the portion of the adjustable section 102 located within the base section 101 has meshing teeth. The meshing teeth contact the adjustment toothed roller, thereby using the forward and reverse rotation of the adjustment motor to drive the adjustment gear to rotate forward or reverse, which in turn can cooperate with the meshing teeth to make the adjustable section 102 move forward or backward, so that one end of the adjustable section 102 enters or extends out of the base section 101, thereby completing the adjustment of the diameter of the overall headband mechanism 1.
[0038] In addition to the head fixing device provided in this application, an adjustment button can be further provided to control the start, stop, forward and reverse rotation of the adjustment motor.
[0039] Preferably, such as Figure 4 Combination Figure 5 As shown, the adjustment assembly in this application includes an adjustment rib, an adjustment drive, and an adjustment gear; a receiving groove 1012 is formed in the base section 101, the adjustment rib is located in the receiving groove 1012, one end of the adjustment rib is connected to the adjustable section 102, and a first meshing part is formed on a portion of the wall surface of the other end, the output end of the adjustment drive is connected to the adjustment gear, and the adjustment gear meshes with the adjustment rib.
[0040] In this embodiment, the adjusting rib can be made of metal to ensure that it remains in an arc shape within the receiving groove 1012. Correspondingly, the adjustment drive in this embodiment is a motor. By forming a first meshing portion on the side wall of the adjusting rib, the position of the adjusting rib can be adjusted after the adjustment drive is activated through the meshing of the adjusting gear with the first meshing portion. Since the other end of the adjusting rib is connected to the adjustable section 102, the position of the adjustable section 102 can be changed when the position of the adjusting rib changes.
[0041] In this example, the adjusting rib can also be a sheet-like structure, thereby providing a basis for the formation of the first engagement part. The difference between this embodiment and the previous embodiment is that in this embodiment, the adjusting rib is always in the receiving groove 1012 of the base section 101 and only serves as an adjusting structure. The headband mechanism 1 mentioned above is formed by the docking of the base section 101 and the adjustable section 102.
[0042] It should be noted that the end of the adjusting rib away from the adjustable section 102 in this application can further form a first limiting protrusion. Correspondingly, a second limiting protrusion is formed at the corresponding position in the receiving groove 1012. When the first limiting protrusion and the second limiting protrusion come into contact, the adjusting rib drives the adjustable section 102 to extend to the maximum adjustment position. At this time, the diameter of the overall headband mechanism 1 is at its maximum.
[0043] Based on this, such as Figure 4 Combination Figure 5 As shown, a guide groove 1011 is formed on the inner side of the base section 101 in this application, and the guide groove 1011 is arranged along the arc direction of the base section 101; a positioning protrusion 1013 is formed in the guide groove 1011, and a mating recess 1023 is formed on the adjustable section 102 corresponding to the position of the positioning protrusion 1013.
[0044] The base segment 101 in this application has a C-shaped cross-section, which enables the initial positioning of the adjustable segment 102 and prevents radial rotation of the adjustable segment 102 during adjustment.
[0045] It is understandable that, since the adjustable section 102 needs to move relative to the base section 101, the outer contour dimension of the adjustable section 102 needs to be slightly smaller than the contour dimension of the guide groove 1011. This application further forms a positioning protrusion 1013 in the guide groove 1011 and a mating recess 1023 at the position of the adjustable section 102 corresponding to the positioning protrusion 1013. Through the cooperation of the positioning protrusion 1013 and the mating recess 1023, the stability of the docking between the adjustable section 102 and the base section 101 can be guaranteed to a certain extent, and the amplitude of the movement of the adjustable section 102 during the movement relative to the base section 101 can be reduced to a certain extent, thereby ensuring the stability of the adjustment process.
[0046] Furthermore, such as Figures 1-5 As shown, the adjustment section 1022 includes a positioning section 1021 and an adjustment section 1022. The cross-sectional area of the positioning section 1021 is the same as that of the base section 101, so that the end of the positioning section 1021 abuts against the end of the base section 101. The adjustment section 1022 has the same size as the guide groove 1011, and the adjustment section 1022 is located in the guide groove 1011. The recess 1023 is formed on the adjustment section 1022.
[0047] By making the cross-sectional area of the positioning segment 1021 consistent with the cross-sectional area of the base segment 101, the positioning segment 1021 can be matched with the base segment 101 to form a [structure / structure]. Figures 1-3 The circular headband mechanism 1 shown has the same external dimensions, which can improve the comfort of newborns when wearing it to a certain extent.
[0048] Accordingly, since the adjusting section 1022 in this application needs to be inserted into the guide groove 1011, the size of the adjusting section 1022 needs to be adapted to the size of the guide groove 1011, so that the cross-sectional area of the adjusting section 1022 is smaller than the cross-sectional area of the positioning section 1021. This allows the positioning section 1021 to be used to limit the adjustment of the inner diameter of the overall headband mechanism 1. That is, when the end face of the positioning section 1021 abuts against the end face of the base section 101, the diameter of the headband mechanism 1 is at its minimum size and cannot be further adjusted. The maximum diameter of the headband mechanism 1 is limited by the cooperation of the first limiting protrusion and the second limiting protrusion.
[0049] Optionally, such as Figures 1-3 As shown, the surrounding mechanism 2 in this application includes at least three arc-shaped adjustable supports, which are evenly distributed along the circumference of the headband mechanism 1. The adjustable supports include a support section 201 and a telescopic section 202. The support section 201 is a hollow structure. One end of the support section 201 is connected to the headband mechanism 1, and one end of the telescopic section 202 is slidably connected to the support section 201 and can be retracted or extended from the support section 201. The ends of the telescopic sections 202 of the three adjustable supports that are away from the support section 201 are located on the same horizontal plane, forming a positioning plane. The probe fixing device 3 is connected to the end of the telescopic section 202.
[0050] The telescopic section 202 in this application can be clearance-fitted with the support section 201, thereby enabling the position of the support section 201 and the telescopic section 202 to be adjustable. That is, since there is a gap between the telescopic section 202 and the support section 201, the telescopic section 202 can extend into or be pulled out of the support section 201. Furthermore, the relative position can be fixed after the telescopic section 202 is adjusted to a predetermined position by using friction.
[0051] In this embodiment, the adjustment of the telescopic section 202 needs to be done manually, such as... Figure 1 As shown, since the probe fixing device 3 is connected to the telescopic section 202, medical staff can adjust the position of the telescopic section 202 relative to the support section 201 by pressing or pulling the probe fixing device 3 during adjustment.
[0052] It should be further explained here that the adjustment of the three telescopic sections 202 in this application is carried out simultaneously. Since the insertion and withdrawal of the telescopic sections 202 will affect the distance between the three telescopic sections 202 and the center of the circle, that is, the diameter of the circle formed by the centers of the three telescopic sections 202, and this circle is the cylinder 301 of the probe fixing device 3, a radially extending groove is formed on the connection surface between the telescopic section 202 and the cylinder 301 in this application. Correspondingly, a guide post is formed on the bottom surface of the cylinder 301, and the guide post can be inserted into the groove. The guide post can slide in the groove when the telescopic section 202 is adjusted, thereby realizing the adjustment process of the telescopic section 202.
[0053] Optionally, the adjustable support in this application further includes an elastic element, a retractor, and a pull rope; the elastic element is disposed within the support section 201, with one end abutting against the bottom of the support section 201 and the other end connected to the end of the telescopic section 202 located within the support section 201; the retractor is located at the bottom of the support section 201; the pull rope is wound inside the retractor, and one end of the pull rope is connected to the telescopic section 202.
[0054] By incorporating an elastic element within the support section 201, stable support for the telescopic component can be achieved. Without external force, the elastic element consistently pushes the support section 201 to its maximum extension position. However, when it is necessary to further align the telescopic section 202 with the newborn's head, a retractor can be used to pull the cord, allowing the telescopic section 202 to extend into the support section 201. In this state, the elastic element is compressed. When the retractor releases its pull, the elastic element gradually springs back, thus pushing the telescopic section 202 back to its maximum extension position.
[0055] It should be noted that the retractor in this application is an electric retractor. Of course, the adjustment button for the telescopic section 202 can also be integrated into the headband mechanism 1 to achieve automatic adjustment of the telescopic section 202. Accordingly, the adjustment of the adjustable section 102 and the telescopic section 202 can be further controlled by a control board within the headband mechanism 1. The adjustment process only involves starting and reversing the motor, so no complex logic program is required, and both can be implemented using existing PCB boards, which will not be elaborated further here.
[0056] Preferably, in this application, at least the inner sides of the basic segment 101 and the adjustable segment 102 are covered with a soft covering layer.
[0057] The outer shells of the headband mechanism 1 and the surrounding mechanism 2 in this application can both be made of plastic material, thereby reducing the weight of the overall device. Since plastic material is rigid and the headband mechanism 1 needs to be in constant contact with the newborn's head skin during examination, this application avoids direct contact between the rigid material and the newborn's skin by covering the inner side of the base section 101 and the adjustable section 102 with a soft layer, thus preventing the newborn's skin from being indented or even damaged, and improving the comfort of wearing it.
[0058] Furthermore, the inner side of the support section 201 in this application can also be covered with a soft layer, thereby further improving wearing comfort. Since the telescopic section 202 needs to retract or extend from the support section 201, the telescopic section 202 in this application can be made of materials such as plastic or silicone that have a certain strength but are more skin-friendly, in order to ensure wearing comfort to a certain extent.
[0059] Optionally, such as Figures 1-3 As shown, the probe fixing device 3 in this application includes a cylinder 301 and a clamping assembly; a positioning groove is formed inside the cylinder 301, and the clamping assembly includes a positioning ring 302, a first clamping jaw 303 and a second clamping jaw 304. The positioning ring 302 is disposed in the positioning groove, and the first clamping jaw 303 and the second clamping jaw 304 are disposed opposite to each other and are both connected to the positioning ring 302; the first clamping jaw 303 and the second clamping jaw 304 form a clamping space, and the scanning probe 4 is located in the clamping space.
[0060] The body in this application can also be made of plastic material, which can reduce the weight of the overall device to a certain extent. The positioning groove in this application is formed along the inner wall circumferentially of the cylinder 301, which can realize the accommodation and positioning of the positioning ring 302.
[0061] To ensure stable clamping of the scanning probe 4, the first gripper 303 and the second gripper 304 in this application can be made of metal. Therefore, the positioning ring 302 in this application also needs to be made of metal, so that the connection between the first gripper 303 and the second gripper 304 and the positioning ring 302 can be achieved by welding.
[0062] Since the cylinder 301 and the positioning ring 302 are made of different materials, the positioning ring 302 can be embedded in the positioning groove. Furthermore, since the positioning ring 302 is an integral circular structure, the corresponding positioning groove is also an integral circular groove. Therefore, the positioning ring 302 is subjected to more uniform force in the positioning groove, which can avoid the problem of the positioning ring 302 causing damage to the cylinder 301 to a certain extent.
[0063] It should be noted that there can be two positioning slots in this application. The two positioning slots are spaced apart along the axial direction of the cylinder 301. Therefore, there are also two positioning rings 302. Each positioning ring 302 is connected to a first gripper 303 and a second gripper 304, so that the scanning probe 4 can be stably clamped by the four grippers.
[0064] Preferably, such as Figures 1-3 As shown, the neonatal bedside cranial ultrasound scanning system provided in this application further includes a first drive assembly, which includes a drive gear and a drive motor 305; the first gripper 303 and the second gripper 304 each include a clamping part 306 and a telescopic drive, the telescopic drive is fixedly connected to the positioning ring 302 along the radial direction of the positioning ring 302, and the telescopic end of the telescopic drive is connected to the clamping part 306, so that the clamping part 306 can extend and retract along the radial direction of the positioning ring 302; a second engagement part 3021 is formed on the outer wall of the positioning ring 302, the drive gear engages with the second engagement part 3021, and the output end of the drive motor 305 is connected to the second engagement part 3021.
[0065] The telescopic drive in this application can be an electric telescopic rod, which enables the clamping part 306 to move radially, thereby clamping and releasing the scanning probe 4.
[0066] Since the scanning operation requires scanning the newborn's head in multiple directions, this application further forms a second engagement portion 3021 on the outer wall of the positioning ring 302, and further provides a drive gear and a drive motor 305. When the drive motor 305 is started, the positioning ring 302 can rotate relative to the cylinder 301 through the cooperation of the drive gear and the second engagement portion 3021, thereby driving the first gripper 303 and the second gripper 304 to move upward around the cylinder 301.
[0067] Correspondingly, the electric telescopic rod enables the clamping part 306 in the first clamp 303 and the second clamp 304 to move radially. Therefore, through the rotation of the positioning ring 302 and the extension and retraction of the first clamp 303 and the second clamp 304, the scanning end of the scanning probe 4 can form a spherical scanning surface, which can adapt to the head condition of the newborn and achieve all-round scanning.
[0068] In actual operation, the teeth of the first gripper 303 and the second gripper 304 are in a centered position. When it is necessary to grip the scanning probe 4, the electric telescopic rod retracts, controlling the teeth to move away from the center. This expands the gripping space, allowing the gripping probe to enter the driver's space behind the electric telescopic rod. The extension brings the gripping part into contact with the outer wall of the scanning probe 4, thus achieving gripping of the scanning probe 4.
[0069] When a scanning inspection is required, the electric telescopic rod of the first gripper 303 retracts while the electric telescopic rod of the second gripper 304 extends, or vice versa. This allows the scanning probe 4 to move back and forth. When the scanning position needs to be adjusted, the rotation of the positioning ring 302 drives the first gripper 303 and the second gripper 304 to rotate. The extension and retraction process of the electric telescopic rods of the first gripper 303 and the second gripper 304 is then repeated. This enables scanning operations in different positions and directions.
[0070] In a preferred embodiment of this application, multiple airbag columns may be further provided in the positioning groove. The multiple airbag columns are evenly distributed along the circumference of the positioning groove, and airbag columns are provided above and below the positioning ring 302, that is, the airbag columns clamp the positioning ring 302 in the center of the positioning groove.
[0071] Taking eight airbag columns as an example, they are labeled A, B, C, D and a, b, c, d respectively in a clockwise direction. The four airbag columns ABCD are located at the upper end of the positioning ring 302, and the other four abcd are located at the lower end of the positioning ring 302. They correspond one-to-one with each other, and the four airbag columns are arranged in a cross shape and are fixedly connected to the cylinder 301.
[0072] During operation, as the scanning probe 4 swings back and forth, when it swings forward, air A deflates, air a inflates, air C inflates, and air c deflates, causing the positioning ring 302 to tilt. This allows the scanning probe 4 to follow the curvature of the newborn's head to scan the anterior fontanelle. When it swings backward, air A inflates, air a deflates, air C deflates, and air c inflates, causing the positioning ring 302 to tilt in the opposite direction, allowing the scanning probe 4 to swing backward. Alternatively, a pressure sensor can be installed at the scanning end of the scanning probe 4 to control the inflation and deflation of the four airbag columns. Simultaneously, the pressure sensor can also synchronously control the retractor within the support section 201 to pull the telescopic section 202, adjusting the distance between the probe fixing device 3 and the head fixing device 1. This changes the distance between the first gripper 303 and the second gripper 304 and the head fixing device 1, ensuring the scanning probe 4 remains in contact with the newborn's head for optimal scanning results.
[0073] Accordingly, after the back-and-forth swinging scanning operation is completed, the positioning ring 302 rotates 90°, and the scanning probe 4 swings in the left and right directions again by using the extension and retraction of the electric telescopic rod. When the scanning probe 4 moves to the left, B is inflated, b is deflated, D is deflated, and d is inflated, thereby causing the positioning ring 302 to tilt. Correspondingly, when it moves to the right, B is deflated, b is inflated, D is inflated, and d is deflated, thus enabling multi-directional scanning operations.
[0074] It should be further explained here that, taking the forward swing process as an example, the forward swing of the scanning probe 4 can perform one scanning operation, and the return to the center position can also perform one scanning operation. Therefore, the aforementioned forward, backward, left, and right swing processes can actually perform 8 scanning operations, thereby obtaining more accurate images of the intracranial situation and ensuring the examination effect. The aforementioned swing angle can be designed according to the angle required for specific clinical examinations. For example, the range of forward, backward, left, and right swing angles can be 120°, that is, with the axis of the scanning probe 4 in its initial clamping state as the reference, after swinging forward to the final position, the angle between the axis of the scanning probe 4 and the axis of the initial state is 60°. However, other angles are also possible, depending on the actual clinical situation.
[0075] The inflation and deflation process described above in this application can be achieved using a pressure sensor. Of course, in order to supply gas to the airbag column, an air pump and an air tube can be further equipped on the ultrasonic scanning equipment. The air tube is connected to the airbag column, and the air pump is used to supply gas. This control process can also be achieved through the existing airbag inflation and deflation control system, which will not be elaborated here.
[0076] It should be further explained here that the airbag inflation and deflation operation described above in this application can be controlled by an integrated control chip in the head fixation device 1. The inflation and deflation of the airbag and the winding and release of the retractor can be automatically controlled by a program. This process can be achieved by a pressure sensor. That is, when the pressure sensor of the scanning probe 4 senses pressure, the airbag can be automatically inflated and deflated and the retractor can be automatically wound and released, thereby realizing the automatic scanning action of the scanning probe 4.
[0077] When the scanning probe 4 can perform automatic scanning, it frees up the ultrasound doctor. The scanning can be completed simply by the nurse putting the device on the newborn's head. This can greatly save the time required for scanning, improve the efficiency of the examination, improve the image quality, and reduce the risks encountered during the examination of premature infants.
[0078] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0079] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
