Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a support device for an ultrasound probe and an ultrasound device. Background Technology

[0002] Ultrasound equipment, as the most numerous, most widely used, safest, fastest-resulting, and most cost-effective image analysis and diagnostic tool among medical imaging devices, has seen particularly rapid development in recent years. Besides diagnosis, ultrasound equipment is also frequently used in interventional ultrasound-guided procedures, which utilize real-time ultrasound guidance to accurately reach the target location within the body. During interventional ultrasound-guided procedures, a sterile sheath must be placed over the ultrasound probe to ensure its sterility, and the procedure is usually performed by a single operator without an assistant.

[0003] In existing technology, a probe cup for holding the ultrasound probe can be provided on the side of the ultrasound device body. During use, the operator can remove the ultrasound probe from the probe cup and place it in the groove next to the probe cup for applying coupling agent and covering with a sterile sleeve. However, because the distance between the upper part of the ultrasound probe and the ultrasound device body is insufficient when the ultrasound probe is placed in the groove, it is easy to come into contact with the surface of the ultrasound device body, resulting in contamination of the sterile sleeve. Utility Model Content

[0004] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a support device for an ultrasonic probe is provided. The support device includes a mounting base located at its bottom, a support position, and a longitudinal structure extending along the height direction below the support position. The longitudinal structure has a first height. A cable channel is provided inside the support device, extending from the mounting base to the top surface of the support device. A support portion is formed on the top of the support device around the upper end of the cable channel. The support portion is used to support an ultrasonic probe placed with its detection surface facing upwards, and the cable channel is used for the passage of the ultrasonic probe's cable.

[0005] For example, the support device further includes a cable passage, wherein: along the height direction, the cable passage extends from the bottom of the mounting base to the top of the support device; and along a lateral direction perpendicular to the height direction, the cable passage extends from the outer side of the support device to the inner side of the support device to connect to a cable channel.

[0006] For example, the cable port is located on the rear side of the support device.

[0007] For example, the support device also has a retractable station, the support device can be changed between the support station and the retractable station, and the support device has a second height less than the first height in the retractable station.

[0008] For example, the support device includes: a plurality of sleeves, each of the plurality of sleeves having an inner cavity extending along the height direction, the inner cavity forming a cable channel, the plurality of sleeves being sequentially inserted along the height direction, and for any two adjacent sleeves, one sleeve being extendable between an extended position extending from the other sleeve and a retracted position retracted from the other sleeve, such that the support device is changeable between a support position and a retracted position; and a locking assembly disposed between the plurality of sleeves, the locking assembly locking the relative positions of the plurality of sleeves when the support device is in the support position.

[0009] For example, the plurality of sleeves includes a first sleeve located at the topmost layer and a second sleeve disposed adjacent to the first sleeve below it. The locking assembly includes a first locking assembly, through which the first sleeve and the second sleeve are locked and unlocked. The first locking assembly includes a first bolt and a first locking groove. The first bolt is disposed on one of the first sleeve and the second sleeve, and the first locking groove is disposed on the other of the first sleeve and the second sleeve. The first bolt moves between a first engaged position extending into the first locking groove and a first unlocked position exiting the first locking groove, wherein: the first bolt is operable to move from the first engaged position to the first unlocked position; and the first bolt is configured to be subjected to an elastic force toward the first engaged position.

[0010] For example, the first locking tongue is connected to an operating part that can operate the first locking tongue. The operating part is located outside the second sleeve when the first sleeve is in its extended position, and inside the second sleeve when the first sleeve is in its retracted position.

[0011] For example, the first locking tongues are arranged in pairs on both sides of the first sleeve.

[0012] For example, the plurality of sleeves also includes one or more third sleeves disposed adjacent to the second sleeve below it. The locking assembly also includes a second locking assembly, wherein any two adjacent sleeves among the second sleeve and the one or more third sleeves are locked and unlocked by the second locking assembly. The second locking assembly includes a second latch disposed on one of the two adjacent sleeves and a second lock groove disposed on the other of the two adjacent sleeves. The second latch is movable between a second engaged position extending into the second lock groove and a second unlocked position retracting from the second lock groove. The second latch is located in the second unlocked position when the sleeve above the two adjacent sleeves is in its retracted position. The second latch is configured to be subjected to an elastic force toward the second engaged position.

[0013] For example, the second lock assembly further includes a transmission member pivotally disposed on the inner sleeve of two adjacent sleeves about a horizontal axis. The first end of the transmission member is connected to or abuts against the second locking tongue. The second end of the transmission member extends into the inner cavity of the inner sleeve when the second locking tongue is in the second locked position. When the second locking tongue is in the second locked position, it extends out of the outer wall of the inner sleeve and into the second locking groove. When the sleeves above the two adjacent sleeves move to their retracted position, the second end of the transmission member pivots downward, and the second locking tongue moves to the second unlocked position under the action of the transmission member.

[0014] For example, for any two adjacent sleeves among a plurality of sleeves, the cross-sectional area of ​​the upper sleeve is smaller than that of the lower sleeve.

[0015] For example, the cross-sections of the multiple sleeves are non-circular.

[0016] For example, a guide portion extending in the height direction is provided between any two adjacent sleeves in a plurality of sleeves.

[0017] For example, for any one of a plurality of sleeves located in the middle along the height direction, the locking assembly between the sleeve and the sleeve above it is offset along the circumferential direction of the sleeve relative to the locking assembly between the sleeve and the sleeve below it.

[0018] For example, the inner side of the support is funnel-shaped, wider at the top and narrower at the bottom.

[0019] For example, the mounting base is removable.

[0020] Another aspect of this application provides an ultrasonic device, including an ultrasonic device body and the aforementioned support device.

[0021] In the technical solution provided in this application, because the support device has a longitudinal structure, it can be located far from the main body of the ultrasonic equipment. During the process of applying the sterile sheath, the operator can place the ultrasonic probe with its detection surface facing upwards on the support. Furthermore, because the support device has a longitudinal structure, the opening of the sterile sheath can easily accommodate the support device within it, without obstructing the application process or contaminating the outer surface of the sterile sheath. During use, the support can support the cable and bear part of its weight, reducing the operator's burden during prolonged operation. As described in the background art, in the prior art, after the ultrasonic probe is covered with a sterile sheath, it is usually not placed back in the probe cup. The operator typically places the ultrasonic probe on a smooth sterile drape, but this easily leads to it slipping to the ground and causing damage. In this application, the operator can place the ultrasonic probe with its detection surface facing upwards on the support for a short rest during use, thus further solving the problem of hand soreness and fatigue. Because the support is sufficiently high above the ground, even if the ultrasonic probe accidentally falls, it will be pulled by the cable and will not fall to the ground.

Detailed Implementation

[0034] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0035] like Figure 1 As shown, this application provides a support device for an ultrasonic probe, used to support an ultrasonic probe placed with its probe surface facing upwards. The support device includes a mounting base 100 located at its bottom. The mounting base 100 can be a separate structure from the other parts of the support device, or it can be integrally formed with the other parts of the support device. The mounting base 100 is used to fix the support device to the main body of the ultrasonic equipment. Taking a common trolley-type ultrasonic equipment as an example, the main body of such ultrasonic equipment may have supports on the left and right sides, and the mounting base is preferably fixed to the supports, or arranged side by side with the supports. Different models of ultrasonic equipment may have different shapes of supports; therefore, the mounting base 100 may also have different shapes for different models of ultrasonic equipment.

[0036] A cable channel 200 may be provided within the support device, extending from the mounting base 100 to the top surface of the support device. Preferably, the cable channel 200 may have an opening at the center of the top surface of the support device. A support portion 300 may be formed around the upper end of the cable channel 200 at the top of the support device, supporting an ultrasonic probe placed with its detection surface facing upwards. The cable channel 200 extending to the top surface of the support device prevents the ultrasonic probe from falling due to instability when placed on the support device. The cable channel 200 may have an opening at the center of the bottom surface of the mounting base 100 or on a side of the mounting base 100. The cable channel 200 allows the ultrasonic probe cable to pass through. For ease of manufacturing, the cable channel 200 may have a circular or near-circular cross-section. For ease of description, a cable channel 200 with a circular cross-section will be described in detail below. However, this does not mean that this application does not include embodiments where the cross-section of the cable channel 200 is polygonal or irregularly shaped.

[0037] In some embodiments, the cable channel 200 may have a large diameter. The connector connecting the ultrasonic probe to the main body of the ultrasonic device can be inserted into the cable channel 200 located at the top of the support device in a detached state, and exit from the opening of the cable channel 200 on one side of the mounting base 100. However, the ultrasonic probe cannot enter the cable channel 200. In this way, the cable of the ultrasonic probe can be partially accommodated within the cable channel 200, making it less prone to tangling and damage. The cable of the ultrasonic probe can also be inserted into the cable channel 200 in any other suitable manner, such as by making the support device detachable to accommodate the cable, or by providing a cable passage structure. The support device has a support position, similar to the retractable position mentioned below. The support position and retractable position refer to different working states of the support device, and do not imply that the support device has any physical support parts such as a support plane. The support device is a longitudinally elongated structure extending along the height direction below the support position, and the longitudinally elongated structure has a first height. The support device can be set vertically or at a certain angle to the vertical direction.

[0038] During operation, the ultrasonic probe is generally not positioned directly above the support 300, but rather to its side. Specifically, depending on the detection location, the ultrasonic probe may be located directly to the side, slightly above, or slightly below the support 300. This ensures the cable contacts the support 300 and is supported at the contact point. For example, if the ultrasonic probe is positioned slightly below the support 300, the cable from the probe to the support 300 extends horizontally and droops due to gravity. Most of the weight is borne by the support 300, with only a small portion borne by the operator. The cable within the cable channel 200 and the cable extending from the opening of the cable channel 200 on the mounting base 100 to the main body of the ultrasonic device experience almost no weight on the operator. This significantly reduces hand pain during ultrasonic probe operation. Furthermore, the support 300 is positioned at a sufficient height from the ground. When the ultrasonic probe is placed on the support 300, even if it falls accidentally, the cable can be pulled by the support 300, thus preventing the ultrasonic probe from falling to the ground and being damaged.

[0039] In the technical solution provided in this application, because the support device has a longitudinal structure, it can be located far from the main body of the ultrasonic equipment. During the process of applying the sterile sheath, the operator can place the ultrasonic probe with its probe surface facing upwards on the support part 300. Furthermore, because the support device has a longitudinal structure, the opening of the sterile sheath can easily accommodate the support device within it, without obstructing the application process or contaminating the outer surface of the sterile sheath. During use, the support part 300 can support the cable and bear part of its weight, reducing the operator's burden during prolonged operation. In the prior art, after the ultrasonic probe is covered with a sterile sheath, it is usually not returned to its original position. The operator typically places the ultrasonic probe on a smooth sterile drape, but this easily leads to it slipping to the ground and causing damage. In this application, the operator can place the ultrasonic probe with its probe surface facing upwards on the support part 300 for a short rest during use, thus further addressing the problems of hand soreness and fatigue. The support unit 300 is far enough away from the main body of the ultrasound device to prevent the sterile sleeve from coming into contact with the surface of the ultrasound device and becoming contaminated. Because the support unit 300 is at a sufficient height from the ground, even if the ultrasound probe accidentally falls, it will be pulled by the cable and will not fall to the ground.

[0040] Exemplarily, the support device may further include a cable passage 210. The cable passage 210 extends from the bottom of the mounting base 100 to the top of the support device along the height direction. And along the lateral direction perpendicular to the height direction, the cable passage 210 extends from the outer side of the support device to the inner side of the support device to connect to the cable channel 200. Providing a cable passage 210 connecting to the cable channel 200 allows the cable to enter the cable channel 200 from the lateral direction. The diameter of the cable channel 200 can be only slightly larger than the diameter of the cable, but not larger than the diameter of the aforementioned connector, thus preventing the cable from swaying within the cable channel 200. During the installation or removal of the cable from the cable channel 200, it is not necessary to cut or connect the cable. For ease of processing, preferably, the cable passage 210 can be arranged in a straight line as shown in the figure. In embodiments not shown, the cable passage can also be arranged in a curve, as long as the cable passage is continuous and does not cause the cable to get stuck in the cable passage during entry into the cable channel.

[0041] In the above technical solution, by providing the cable passage 210, the cable can be moved into or removed from the cable channel 200 without damage. Since the connector between the cable and the main body of the ultrasonic device does not need to pass through the cable channel 200, the size of the cable channel 200 can be correspondingly reduced, only slightly larger than the cable size. This provides a limiting effect on the cable, preventing it from swaying. Provided the strength of the support device is ensured, the smaller the diameter of the cable channel 200, the thinner the support device can be, making it easier to attach a sterile sleeve. A smaller support device can also reduce its cost.

[0042] For example, the cable passage 210 can be located on the rear side of the support device. The rear side of the support device can be relative to the main body of the ultrasound device; the side facing the front of the ultrasound device's display can be considered the front side of the support device, and the side facing the back of the ultrasound device's display can be considered the rear side of the support device. As described above, during the operator's use of the ultrasound probe, the ultrasound probe may be located to the side of the support device. In this case, the cable passage 210 can be positioned away from this side in the lateral direction. This ensures that the ultrasound probe cable contacts the side of the support device away from the cable passage 210, thereby preventing the cable from accidentally passing through the cable passage 210 and detaching from the cable channel 200 during use.

[0043] like Figure 2As shown, exemplarily, the support device also has a retractable position, which is switchable between the support position and the retractable position. In the retractable position, the support device has a second height less than the first height. During the operation of the ultrasound equipment, supporting the ultrasound probe and cable at a higher height facilitates the application of sterile sheaths, ultrasound probe detection, and probe placement. However, after ultrasound interventional treatment, a longer support device can cause inconvenience during equipment transfer and is susceptible to bending or even breakage due to accidental impacts. The retractable position at the second height effectively prevents collisions with surrounding objects. The support device can change its length through methods such as folding or nesting, switching between the first height support position and the second height retractable position.

[0044] Exemplarily, the support device may include a plurality of sleeves 400, each of which has a hollow inner cavity forming a cable channel 200. The plurality of sleeves 400 can be sequentially inserted along the height direction. For any two adjacent sleeves, one sleeve is extendable between an extended position extending from the other sleeve and a retracted position retracted from the other sleeve, allowing the support device to be switched between a supporting position and a retracted position. Compared to embodiments with a folding structure, using a plurality of sequentially insertable sleeves allows the support device to be generally cylindrical in shape when in the retracted position, with almost no lateral protrusion, thus occupying less space. In one exemplary embodiment, the support device may include a larger sleeve with two smaller sleeves at its ends, the two smaller sleeves retracting into the larger sleeve. In another embodiment, the support device may also include a larger sleeve with two larger sleeves at its ends, the two larger sleeves fitting onto the smaller sleeves. In short, the support device can be extended and retracted as long as one sleeve is retracted into another sleeve.

[0045] Operators typically do not want the height of the support device to change during operation; therefore, the support device is preferably kept in the support position. In some embodiments, each sleeve can have a large frictional force, preventing it from being easily pushed to the retracted position when in the support position. Preferably, the support device may also include a locking assembly, which can be disposed among the multiple sleeves 400. The locking assembly locks the relative positions of the multiple sleeves 400 when the support device is in the support position. This avoids the support device consuming excessive physical strength from the operator and, during long-term use, prevents the frictional force between the sleeves from decreasing due to sleeve aging or other reasons, thus preventing difficulty in maintaining the support position during use.

[0046] For example, for any two adjacent sleeves among a plurality of sleeves, the cross-sectional area of ​​the upper sleeve is smaller than that of the lower sleeve. This allows the support device to form a pyramid shape that tapers from bottom to top when in the support position, with the larger base able to withstand greater external forces, making the overall structure more robust. Furthermore, the upper sleeve can be completely retracted into the lower sleeve, allowing for a lower height of the support device when the position is retracted. In addition, this configuration simplifies the structure of the support device and reduces costs.

[0047] In an embodiment where the cross-sectional area of ​​the upper sleeve is smaller than that of the lower sleeve, a flange may be provided on the top of the upper sleeve. The size of the flange is such that it prevents the upper sleeve from completely entering the adjacent lower sleeve and from falling out of the cable channel.

[0048] Exemplarily, the plurality of sleeves 400 may include a first sleeve 410 located at the topmost level and a second sleeve 420 disposed adjacent to the first sleeve below it. In an exemplary embodiment, the support device may include only the first sleeve 410 and the second sleeve 420. In other embodiments, the support device may also include a third sleeve. With the same first height for the support device, appropriately increasing the number of sleeves can shorten the length of each sleeve segment, allowing most sleeves to retract into their adjacent sleeves when the support device is in the retracted position, thereby further reducing the second height. Correspondingly, the locking assembly may include a first locking assembly 500, through which the first sleeve 410 and the second sleeve 420 are locked and unlocked. The first locking assembly 500 may include a first locking tongue 510 and a first locking groove 520. The first locking tongue 510 is disposed on one of the first sleeve 410 and the second sleeve 420, and the first locking groove 520 is disposed on the other of the first sleeve 410 and the second sleeve 420. The first locking tongue 510 can move between a first locked position extending into the first locking groove 520 and a first unlocked position exiting the first locking groove 520. In the specific embodiment shown in the figure, the first locking tongue 510 may include a smooth head, which can avoid scratching the inner surface of the second sleeve 420 and can also guide when aligning with the first locking groove 520, so that the first locking tongue 510 can smoothly enter the first locking groove 520. The first locking groove 520 may be formed by an opening or a recess formed on the second sleeve 420. When the first locking tongue 510 extends into the first locking groove 520 on the second sleeve 420, the cylindrical portion other than the head can lock the first locking groove 520, thereby fixing the first sleeve 410 and the second sleeve 420 to each other in the axial direction. In other embodiments, the first locking tongue 510 may also be disposed on the second sleeve 420, and the first locking groove 520 may be disposed on the first sleeve 410. The first locking tongue 510 may also have other shapes, as long as it can cooperate with the first locking groove 520 to lock the first sleeve 410 and the second sleeve 420 when it is in the first locked position.

[0049] The first locking tongue 510 is operable to move from a first locked position to a first unlocked position, and the first locking tongue 510 is configured to be subjected to an elastic force toward the first locked position. Figure 5 and Figure 6 In the illustrated embodiment, the support device may include an elastic element, such as a spring. The spring may be disposed between the first latch 510 and the first sleeve, and applies an elastic force to the first latch 510 toward the first locking position. In the embodiment shown, the first latch 510 and the first sleeve 410 may be connected by an elastic portion. Specifically, for example, the first sleeve 410 may be made of elastic steel, and the first latch 510 and the elastic portion connecting the main body of the first latch 510 and the first sleeve 410 may be formed by cutting. In other words, the first sleeve 410, the elastic portion, and the first latch 510 may be integrally formed. In some embodiments, the first latch 510 and the elastic portion may be integral, connected to the surface of the first sleeve 410 by welding or other means. In summary, the elastic force can cause the first latch 510 to be biased toward the first locking position. In the embodiment described above where the first locking tongue 510 is disposed on the first sleeve 410, when using a support device, as the first sleeve 410 moves from the retracted position to the extended position, the first locking tongue 510 can always abut against the inner wall of the second sleeve 420 under the action of elastic force. When the first locking tongue 510 and the first locking groove 520 are aligned, under the action of elastic force, the first locking tongue 510 inserts into the first locking groove 520, thereby reaching the first locking position, making the first sleeve 410 and the second sleeve 420 unable to move relative to each other. The first locking tongue 510 is operable and can be moved to the first unlocking position under the action of external force. At this time, the first locking tongue 510 exits the first locking groove 520, and the first sleeve 410 and the second sleeve 420 are movable relative to each other.

[0050] For example, the first locking tongue 510 is connected to an operating part 530 that can operate the first locking tongue 510. The operating part 530 is located outside the second sleeve 420 when the first sleeve 410 is in its extended position, and inside the second sleeve 420 when the first sleeve 410 is in its retracted position. (Continue to refer to...) Figure 5 and Figure 6The operating part 530 can be integrated with the first locking tongue 510 and the elastic part, and extends from the first locking tongue 510 in the extension direction of the first sleeve 410. When the first sleeve 410 is in the extended position, the first locking tongue 510 is inserted into the first locking groove 520, and the first locking tongue 510 can be completely covered by the second sleeve 420. When the operating part 530 is pressed in the direction of the first unlocking position, it can drive the first locking tongue 510 to overcome the elastic force of the elastic part, so that the first locking tongue 510 reaches the first unlocking position. When the first sleeve 410 is in its retracted position, since there is no locking relationship between the first sleeve 410 and the second sleeve 420, there is no need for the operating part 530 to unlock. At this time, the operating part 530 and the second sleeve 420 can be configured such that the operating part 530 can retract into the second sleeve 420, thereby avoiding the failure or even detachment of the elastic part due to external force. Under the aforementioned elastic force, the first locking tongue 510 and the operating part can protrude from the surface of the first sleeve 410 in both the natural state and when the first and second sleeves are locked, to facilitate pressing by the operator. In other embodiments, the operating part 530 can be connected to other locations to transmit the force applied by the operator to the first locking tongue 510 in a suitable manner, thereby moving the first locking tongue 510 to the first unlocked position.

[0051] For example, the first latches 510 are arranged in pairs on both sides of the first sleeve 410. As described above, the operator can press the operating part 530 on the first sleeve 410 to operate the first latches 510. For one operating part 530, during the pressing process, the opposite side is usually pressed at the same time, thereby avoiding the pressing force causing the first sleeve 410 and the operating part 530 to move together, making it difficult for the operating part 530 to bear force. Arranging the first latches 510 and the operating parts 530 in pairs on both sides of the first sleeve 410 not only makes the locking between the first sleeve 410 and the second sleeve 420 more reliable through the two first latches 510, but also the operation habits of ordinary people are suitable for pressing the operating parts 530 on both sides to move the two first latches 510 to the first unlock position. Preferably, the line connecting the two operating parts 530 and the center of the first sleeve 410 has an angle of 180 degrees.

[0052] Exemplarily, the plurality of sleeves 400 also includes one or more third sleeves 430 disposed adjacent to each other below the second sleeve 420, and the locking assembly includes a second locking assembly 600, wherein any two adjacent sleeves among the second sleeve 420 and the one or more third sleeves 430 are locked and unlocked by the second locking assembly 600. Figure 3 and Figure 4In the illustrated embodiment, the second sleeve 420 and the adjacent inner third sleeve 431 can be locked together by a set of second locking components 600. If there are multiple third sleeves 430, each pair of adjacent third sleeves can be locked together by another set of second locking components 600. (Continue referring to...) Figure 3 and Figure 4 The inner third sleeve 431 and the outer third sleeve 432 can be locked and unlocked by the second locking assembly 600. The second locking assembly 600 between adjacent second sleeves 420 and third sleeves and the second locking assembly 600 between two adjacent third sleeves can be structurally the same or different.

[0053] The second locking assembly 600 may include a second locking tongue 610 disposed on one of two adjacent sleeves, and a second locking groove 620 disposed on the other of the two adjacent sleeves. The second locking tongue 610 is movable between a second locked position extending into the second locking groove 620 and a second unlocked position exiting the second locking groove. Figure 5 and Figure 7 In the specific embodiment shown, taking the second locking assembly 600 between the second sleeve 420 and the adjacent third sleeve (i.e., the inner third sleeve 431) as an example, the second sleeve 420 may be provided with a groove to accommodate the second locking tongue 610, which may be guided by the groove. Similar to the first locking tongue 510, the second locking tongue 610 may be constructed in a bullet shape with a smooth head to prevent scratching the inner wall of the inner third sleeve 431 and to serve as a guide.

[0054] For example, multiple second locking components 600 can be arranged in pairs and symmetrically on both sides of the support device, with each pair of second locking components 600 being approximately equidistant from the wire passage 210, thereby reasonably distributing the force. In an embodiment not shown, the second locking components can also be arranged on the side opposite to the wire passage, sharing the force distribution with the aforementioned paired second locking components. Of course, there can also be more than one second locking component 600.

[0055] For example, for any sleeve located in the middle along the height direction among a plurality of sleeves, the locking assembly between this sleeve and the sleeve above it can be offset relative to the locking assembly between this sleeve and the sleeve below it along the circumferential direction of the sleeve. Taking the first sleeve 410, the second sleeve 420 and the inner third sleeve 431 as examples, the angle between the line connecting the first locking assembly of the first sleeve 410 and the center of the sleeve and the line connecting the thread pass 210 and the center of the sleeve can be a first angle, and the angle between the line connecting the second locking assembly of the second sleeve 420 and the center of the sleeve and the line connecting the thread pass 210 and the center of the sleeve can be a second angle. The first angle and the second angle can be different. In other words, the projection of the first locking assembly on the horizontal plane and the projection of the second locking assembly on the horizontal plane can be offset in the circumferential direction. This makes the support device more robust.

[0056] The second latch 610 can be in a second unlocked position when the sleeves above the two adjacent sleeves are in their retracted positions. The second latch 610 can be configured to receive an elastic force toward the second locked position. A spring 611 can be disposed in the aforementioned groove and apply an elastic force toward the first locked position to the second latch 610. The other side of the spring 611 can abut against the fixing plate 422 formed by the sleeves. In other embodiments, the end of the first latch 510 can be configured to have an elastic structure; for example, the tail portion of the second latch opposite the head can be machined to form a spring clip. In some embodiments, the second latch 610 can be partially or entirely made of an elastic material such as polyurethane. When using the support device, as the second sleeve 420 moves from the retracted position to the extended position, the second latch 610 can always abut against the inner wall of the inner third sleeve 431 under the action of the elastic force. When the second latch 610 and the second locking groove 620 are aligned, under the action of elastic force, the second latch 610 inserts into the second locking groove 620, thereby reaching the second locked position, making the second sleeve 420 and the inner third sleeve 431 unable to move relative to each other. When the first sleeve 410 retracts into the second sleeve 420 and reaches the retracted position, force can be applied to the second latch 610 to move it to the second unlocked position. At this time, the second latch 610 exits the second locking groove 620, and the second sleeve 420 and the inner third sleeve 431 can move relative to each other.

[0057] Therefore, after the user presses the first sleeve 410 to the retracted position, the second locking assembly 600 between the second sleeve 420 and the adjacent third sleeve automatically unlocks, allowing the user to press the second sleeve 420 to its retracted position. When there are multiple third sleeves 430, when the second sleeve 420 is in the retracted position, it can further unlock the second locking assembly 600 between the inner third sleeve 431 and the outer third sleeve 432, allowing the inner third sleeve 431 to be pressed to its retracted position. Thus, only one operating unit 530 is needed to interlock and move all movable sleeves 400 of the support device to the retracted position. It is not necessary to have an operating unit 530 for each locking assembly. The figure only shows an embodiment where the third sleeve 430 includes the inner third sleeve 431 and the outer third sleeve 432. When there are more third sleeves 430, the unlocking logic of the locking assembly can be similar to the unlocking logic described above.

[0058] Exemplarily, the second locking assembly 600 may further include a transmission member 630, which is pivotally disposed on the inner sleeve of two adjacent sleeves about a horizontal axis. The first end 631 of the transmission member 630 connects to or abuts against the second locking tongue 610. The second end 632 of the transmission member 630 can extend into the inner cavity of the inner sleeve when the second locking tongue 610 is in the second locked position. When the second locking tongue 610 is in the second locked position, it extends beyond the outer wall of the inner sleeve and into the second locking groove 620. When the sleeves above the two adjacent sleeves move to their retracted position, the second end 632 of the transmission member 630 can pivot downwards, and the second locking tongue 610 moves to the second unlocked position under the action of the transmission member 630. In the embodiments described above, reference continues... Figure 5 and Figure 7 The second locking tongue 610 is installed in the groove and guided by the groove in the lateral direction. The movement directions of the first sleeve 410, the second sleeve 420, and the inner third sleeve 431 are all vertical, perpendicular to the movement direction of the second locking tongue 610. The transmission member 630 can convert the vertical force into a force with a lateral component and transmit it to the second locking tongue 610, enabling it to overcome the elastic force and move to the second unlocking position. Specifically, taking the second sleeve 420 and the inner third sleeve 431 as examples, the transmission member 630 can be corner-shaped, with a pivot shaft at the corner. When the first sleeve 410 reaches the retracted position, its end first push groove 412 can abut downward against the second end 632 of the transmission member 630, thereby generating a torque on the pivot shaft of the transmission member 630. The first end of the transmission member 630 then moves towards the second unlocking position and drives the second locking tongue 610 to move through the groove on the second locking tongue 610. Similarly, Figure 7The diagram shows a second push groove 421 at the end of the second sleeve, which also serves to abut against the second end of the corresponding transmission member, thereby unlocking the second lock assembly. In some embodiments, the bottom edge of the sleeve 400 may also abut against the second end 632 of the transmission member 630. In embodiments not shown, the corresponding second latch may also be moved in other ways when the first, second, and third sleeves reach the retracted position, such as by using a magnet to attract and repel the second latch.

[0059] For example, the cross-sections of the multiple sleeves 400 can be non-circular. For instance, the cross-sections can be elliptical, rounded rectangles, rectangular, etc. This allows for a simpler structure, preventing adjacent sleeves from rotating relative to each other and thus avoiding misalignment of the cable passage 210. This ensures that cables can smoothly enter and exit the cable channel 200 through the cable passage 210 and also prevents misaligned cable passages 210 from shearing or scratching the cable. In one specific embodiment, the support device can, after assembly, process the circular cross-section of the sleeves 400 together into an elliptical cross-section using methods such as stamping. Of course, in other embodiments, the sleeves 400 can be formed with a non-circular cross-section before assembly.

[0060] Exemplarily, a guide portion (not shown) extending along the height direction is provided between any two adjacent sleeves of the plurality of sleeves 400. Similar to the above-described non-circular cross-section of the sleeve 400, the guide portion prevents adjacent sleeves from rotating relative to each other. In one specific embodiment, the sleeves 400 are processed from standard tubing, thus reducing raw material costs. Taking the guide portion between the first sleeve 410 and the second sleeve 420 as an example, the guide portion can be constructed as a groove extending along the inner wall of the second sleeve 420 to the first locking groove 520, the depth of which can be less than the depth of the first locking groove 520. The first locking tongue 510 is embedded in the groove, and during the extension and retraction of the support device, the first locking tongue 510 can also prevent the first sleeve 410 and the second sleeve 420 from rotating out of each other by cooperating with the groove. Of course, this application does not exclude embodiments using any other suitable means of guidance, such as screws and guide grooves.

[0061] For example, the inner surface of the support portion 300 is funnel-shaped, wider at the top and narrower at the bottom. The grip portion connecting the ultrasonic probe to the cable is typically smooth; if the support portion 300 has a flat top surface, placing the ultrasonic probe on it might cause it to slip. Conversely, the larger opening of the funnel-shaped support portion 300 can be larger than the grip portion of the ultrasonic probe, and the smaller opening can be smaller than the grip portion and connect to the cable channel 200. Thus, when the ultrasonic probe is placed with its probe face up on the support portion 300, even if it tipes over, it can be supported by the inner surface of the support portion 300. When the ultrasonic probe is against the side wall of the support portion 300, the center of gravity of the ultrasonic probe can fall within the projection of the support portion 300 onto the horizontal plane, preventing it from tipping over and falling outside the support portion 300, but rather keeping it above the support portion 300. In some embodiments, the grip portion of the ultrasonic probe can gradually narrow towards the cable. When the ultrasonic probe is placed face up on the support 300, the gradually narrowing grip fits snugly against the side wall of the funnel-shaped support 300, thus providing excellent support for the ultrasonic probe. In summary, the funnel-shaped support 300 effectively improves the stability of the ultrasonic probe when placed face up on the support 300. During use, the funnel-shaped support 300 also facilitates the operator in pulling the support device to the designated support position.

[0062] For example, the mounting base 100 is detachable. As mentioned above, different ultrasound devices may have mounting bases 100 with different shapes. The detachability of the mounting base 100 allows the sleeve portion of the support device to be removed from the mounting base 100 of one ultrasound device and connected to the mounting base 100 of another ultrasound device. In this way, corresponding mounting bases 100 can be configured for different ultrasound devices, and the sleeve portion can be universal, eliminating the need for a sleeve to be configured for each mounting base 100, thereby reducing costs.
