Technical Field

[0002] Ultrasonic diagnosis has been widely used in the field of medical testing. Traditional ultrasonic examinations are performed using a manually held ultrasonic probe. Currently, the ultrasonic probe is fixed to the end of a robotic arm to utilize the multi-degree-of-freedom displacement of the robotic arm, which can well replace manual testing.

[0003] In actual application, in order to flexibly replace different ultrasound probes according to the needs of different patients and improve adaptability, different types of ultrasound probes are usually provided with clamping devices adapted thereto, and then the clamping devices are fixed to the end of the mechanical arm to fix the ultrasound probe. The connection between the clamping device and the mechanical arm can be fixed by screws or metal joints.

[0004] However, the fixed connection method between the above-mentioned clamping device and the robotic arm still has the following problems: although the screw fixing method is relatively common, the nut is generally made of metal material, which will result in too high cost when used in disposable equipment, and the bolts / screw holes at the end of the robotic arm are difficult to clean, making it difficult to achieve a sterile environment for ultrasonic inspection; if a metal structure is used for fixing, the metal joint itself has grooves in its structure, making it difficult to clean the inside, and it is also difficult to achieve a sterile environment for ultrasonic inspection.

[0047] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0048] In the description of the embodiments of the present application, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0049] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0050] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0052] In the related art, the clamping device and the robot arm are usually fixed with screws. However, in addition to the high cost and difficulty in cleaning of disposable equipment, the tightening force of the screws is uncontrollable. If the screws are not tightened, the clamping device will shake relative to the robot arm. If the screws are tightened too much, the equipment will be damaged (the clamping device and / or the end of the robot arm are usually made of plastic). In the related art, there is also a method of connecting the clamping device and the robot arm with a metal joint, but it is difficult to achieve a rebound-free or gap-free process when connecting a metal joint to a plastic device (such as a clamping device), and there is also a problem of being difficult to clean.

[0053] Figure 1 is a schematic diagram of the structure of an ultrasonic inspection device provided according to an embodiment of the present application; Figure 2 It is a schematic diagram of the structural decomposition of the mounting device and the chuck of the ultrasonic probe provided in an embodiment of the present application; Figure 3 is a schematic diagram of the structural decomposition of a fixing seat and a clamping mechanism provided according to an embodiment of the present application; Figure 4 It is a schematic diagram of the structural decomposition between the locking mechanism and the rebound mechanism in the fixing seat provided according to the embodiment of the present application.

[0054] Based on the above problems, refer to Figure 3 , Figure 4As shown, the embodiment of the present application first provides a mounting device for an ultrasound probe, which may include a clamping assembly 100 , a fixing seat 200 and a rebound mechanism 400 .

[0055] The clamping assembly 100 includes a connecting member 110, and the clamping assembly 100 is used to detachably connect the ultrasonic probe; a locking mechanism 300 is arranged in the fixing seat 200, and the fixing seat 200 has a mounting surface 240, and the mounting surface 240 is configured with a clearance groove 230, and at least a part of the locking mechanism 300 can extend into the clearance groove 230; the rebound mechanism 400 is arranged in the clearance groove 230; the clamping assembly 100 is suitable for switching between a locked state and a released state. In the locked state, the connecting member 110 is located in the clearance groove 230, and the locking mechanism 300 is triggered to lock the connecting member 110, so as to fix the clamping assembly 100 at the mounting surface 240; in the released state, the rebound mechanism 400 is reset to the mounting surface 240 along the clearance groove 230.

[0056] It can be understood that in this example, the fixing base 200 is fixed to the end of the robot arm 500. Figure 1 As shown, it is mainly used for snap-connecting the clamping assembly 100. Since the fixing seat 200 contains many parts and in order to enhance the connection strength, the fixing seat 200 can be made of metal. Since the manufacturing cost of the fixing seat 200 is relatively high, the fixing seat 200 is not easily replaced. When using different types of ultrasonic probes, it is only necessary to replace the clamping assembly 100 that clamps the ultrasonic probe. In order to adapt and connect with the fixing seat 200, the connecting piece 110 of the clamping assembly 100 can be set to a universal size, so that it can be adapted and snap-connected in the fixing seat 200, thereby achieving the purpose of fixing the ultrasonic probe at the end of the robotic arm 500.

[0057] Since the fixing base 200 provided in this example can be used for a long time, in order to ensure that the mounting surface 240 of the fixing base 200 is easy to clean (when the clamping assembly 100 is not connected), as shown in FIG. Figure 3 As shown, the structure of the fixing seat 200 and the locking mechanism 300 and the rebound mechanism 400 disposed therein are reasonably arranged to ensure that the mounting surface 240 of the fixing seat 200 forms an easy-to-clean surface as much as possible when the clamping assembly 100 is released. Specifically, the mounting surface 240 of the fixing seat 200 is a surface facing the clamping assembly 100. During ultrasonic inspection, a sterile cover will be set around the fixing seat 200. Since the mounting surface 240 of the fixing seat 200 needs to be installed and fixed to the clamping assembly 100, it is impossible to cover it with a sterile cover. Therefore, the cleanliness of the mounting surface 240 needs to be ensured.

[0058] Specifically, in this example, a clearance groove 230 is configured on the mounting surface 240. The clearance groove 230 is used to connect the mounting surface 240 and the interior of the fixing seat 200. The rebound mechanism 400 is arranged in the clearance groove 230. On the other hand, it enables the connecting member 110 of the clamping assembly 100 to enter the fixing seat 200 through the clearance groove 230 to trigger the locking mechanism 300 to lock the connecting member 110. More importantly, the purpose of this arrangement is to enable the rebound mechanism 400 to fill the clearance groove 230 when the clamping assembly 100 is not connected (released state), that is, the outer end surface of the rebound mechanism 400 can achieve the effect of being located at the mounting surface 240, for example, the outer end surface of the rebound mechanism 400 can be flush with the mounting surface 240 to form a complete and easy-to-clean surface.

[0059] When installing the clamping assembly 100 (locked state), the clamping assembly 100 can be held by hand so that the connecting member 110 is aligned with the position of the give way groove 230. Since the rebound mechanism 400 is filled in the give way groove 230, the end of the connecting member 110 first abuts against the outer end surface of the rebound mechanism 400, and under the action of external force, the rebound mechanism 400 is pushed to continue to move into the fixing seat 200. At this time, the rebound mechanism 400 accumulates force, and the connecting member 110 also enters the fixing seat 200 along the give way groove 230. Since the part of the locking mechanism 300 arranged in the fixing seat 200 can extend into the give way groove 230, as the connecting member 110 continues to move, the locking mechanism 300 will be triggered, and the locking mechanism 300 will lock the connecting member 110, thereby achieving the purpose of fixing the ultrasonic probe to the fixing seat 200.

[0060] When the clamping assembly 100 is disassembled (released state), an external force can be applied to the locking mechanism 300, and the locking mechanism 300 immediately releases the connecting member 110. Since the rebound mechanism 400 is in a force storage state in the locked state and continues to abut against the end of the connecting member 110, after the connecting member 110 is released by the locking mechanism 300, the rebound mechanism 400 releases the force on the connecting member 110, thereby popping the connecting member 110 out of the clearance groove 230, thereby releasing the clamping assembly 100. At this time, the outer end surface of the rebound mechanism 400 will also be reset to the position of the mounting surface 240 to form an easy-to-clean surface with the mounting surface 240. Of course, the easy-to-clean surface is not limited to the outer end surface of the rebound mechanism 400 being flush with the mounting surface 240. The outer end surface of the rebound mechanism 400 can also be slightly lower than the mounting surface 240, or slightly higher than the mounting surface 240, so that medical staff can wipe the surface formed by the outer end surface of the rebound mechanism 400 and the mounting surface 240 with a cleaning wipe.

[0061] In the present application, by constructing a clearance groove 230 on the mounting surface 240 of the fixing seat 200, and setting a rebound mechanism 400 in the clearance groove 230, and making the locking mechanism 300 set in the fixing seat 200 in a state that can extend into the clearance groove 230, when the connecting member 110 of the clamping assembly 100 pushes the rebound mechanism 400 to retract into the fixing seat 200, the connecting member 110 can trigger the locking mechanism 300 to be locked, thereby achieving the fixing of the clamping assembly 100 and the fixing seat 200. During the process of removing the clamping assembly 100 from the fixing seat 200, as the locking mechanism releases the connecting member 110 under the action of external force, the rebound mechanism 400 in the force storage state and in contact with the connecting member 110 will pop the connecting member 110 out of the clearance groove 230, and the rebound mechanism 400 will reset to the installation surface 240, and the outer end surface of the rebound mechanism 400 will form an easy-to-clean surface with the installation surface 240 to improve the cleaning ease and cleanliness of the fixing seat 200. In addition, the installation device of this example can realize the rapid installation and removal of the clamping assembly 100 and the fixing seat 200.

[0062] Figure 5 4 is a schematic diagram of the structure decomposition of the rebound mechanism 400 and the clearance groove 230 in the fixing seat 200 according to the embodiment of the present application; Figure 6 is a schematic cross-sectional structural diagram of an installation device for an ultrasound probe provided in an embodiment of the present application; Figure 7 It is a schematic diagram of the structure of the clamping plate 311 provided according to an embodiment of the present application.

[0063] Next, we will combine Figure 1-Figure 7 The specific structure of the installation device of the ultrasound probe provided in the embodiment of the present application is introduced in detail.

[0064] like Figure 5 As shown, in some embodiments, the rebound mechanism 400 includes a first elastic member 420 and a push plate 410, one end of the first elastic member 420 is limited to the fixed seat 200, and the other end is limited to the push plate 410; in the released state, the outer surface of the push plate 410 is flush with the mounting surface 240.

[0065] It can be understood that the first elastic member 420, i.e., the spring, is disposed in the limiting groove, the bottom end of the spring can be fixedly connected to the bottom surface of the limiting groove, and the top end of the spring can be fixedly connected to the bottom surface of the push plate 410. In the released state (the state in which the clamping assembly 100 is not clamped to the fixing seat 200), the outer surface of the push plate 410 is flush with the mounting surface 240 of the fixing seat 200 under the support of the spring. In the locked state, the push plate 410 is pressed into the limiting groove by the connecting member 110, and the spring is compressed so that the spring is in a force storage state. In order to prevent the spring from twisting during compression and release, a guide rod 260 can be disposed in the middle of the spring, the bottom end of which is fixed to the bottom of the limiting groove, and the length of the guide rod 260 needs to be less than the depth of the limiting groove to avoid interference with the locking clamping assembly 100.

[0066] In order to facilitate the installation of the locking mechanism 300 in the fixing seat 200 and the provision of the rebound mechanism 400, the fixing seat 200 may be manufactured in separate parts. Figure 4 and Figure 5 As shown, in some embodiments, the fixed seat 200 includes a fixed shell 210 and a cover plate 220; the fixed shell 210 is configured with an installation cavity and a groove 231, the installation cavity is located outside the groove 231, and the installation cavity is used to set the locking mechanism 300; the cover plate 220 covers the fixed shell 210, and the cover plate 220 is configured with a clearance hole 232, and the clearance hole 232 and the groove 231 form a clearance groove 230; wherein the installation surface 240 is the surface of the cover plate 220 facing away from the fixed shell 210.

[0067] It can be understood that an installation cavity and a groove 231 are constructed at the end of the fixed shell 210 away from the end of the robotic arm 500, and the installation cavity is partially connected to the groove 231 so that the locking mechanism 300 part arranged in the installation cavity can extend into the groove 231. During installation, the rebound mechanism 400 and the locking mechanism 300 part can be arranged on the fixed shell 210 in sequence, and then the cover plate 220 is covered on the fixed shell 210. The setting of the cover plate 220 is to limit the locking mechanism 300 with the installation cavity on the one hand, so as to prevent the locking mechanism 300 from shaking in the fixed seat 200. More importantly, the clearance hole 232 at the cover plate 220 can expose the push plate 410 to a level flush with the outer surface of the cover plate 220, so that the outer surface of the cover plate 220 and the outer surface of the push plate 410 form an easy-to-clean plane.

[0068] To avoid or mitigate the problem of improper cleaning caused by the mismatch between the push plate 410 and the clearance hole 232 of the cover plate 220, in some embodiments, as Figure 3As shown, in the released state, the push plate 410 is adapted to fit in the clearance hole 232. For example, the clearance hole 232 can be set as a square hole, and the push plate 410 can be adapted to be set as a square that fits the square hole, and in order to be able to fit and be embedded in the square hole, the size of the push plate 410 can be slightly smaller than the size of the square hole. Of course, the clearance hole 232 can also be set as a round hole, and the push plate 410 is adapted to be set in a round shape, and the size is slightly smaller than the size of the round hole. The specific shapes of the clearance hole 232 and the push plate 410 are not limited here.

[0069] In one example, the cover plate 220 is provided with a sealing ring (not shown) at the clearance hole 232, and the push plate 410 abuts against the sealing ring in the released state. Specifically, a circle of sealing rings is provided at the clearance hole 232 and near the upper surface of the cover plate 220, so that when the push plate 410 is reset to the cover plate 220, the edge of the push plate 410 can abut against the sealing ring, that is, the gap between the push plate 410 and the cover plate 220 is eliminated by the sealing ring, so that the push plate 410, the sealing ring and the cover plate 220 form a complete plane that is easy to clean, avoiding the existence of dead corners that are difficult to clean.

[0070] like Figure 5 As shown, in some embodiments, the side wall of the groove 231 is configured with a limiting channel 2311 , and the side wall of the push plate 410 is provided with a limiting block 411 adapted to fit with the limiting channel 2311 .

[0071] It can be understood that at least one limiting channel 2311 is constructed in the side wall of the groove 231, that is, the fixed shell 210, and the extension direction of the limiting channel 2311 is consistent with the moving direction of the connecting member 110 along the groove 231. The setting of the limiting channel 2311 can enable the push plate 410 to move along the limiting channel 2311 to reset to the position of the yield hole 232 under the action of the first elastic member 420, thereby avoiding the push plate 410 from being offset during the reset process, and failing to achieve the effect of the surface of the push plate 410 being flush with the upper surface of the cover plate 220.

[0072] like Figure 5 As shown, in some embodiments, the locking mechanism 300 includes a snap-fit ​​component 310 and a pressing component 320. The snap-fit ​​component 310 is arranged in the installation cavity through a second elastic component to form a snap connection with the connecting component 110 under the action of the elastic component; one end of the pressing component 320 is in contact with the snap-fit ​​component 310, and the other end is located outside the fixing seat 200. The pressing component 320 is configured to move the snap-fit ​​component 310 under the action of an external force to release the connecting component 110.

[0073] Specifically, the clamping member 310 and the pressing member 320 are installed separately, and the clamping member 310 is arranged in the installation cavity by a second elastic member, namely a spring. When the connecting member 110 has not entered the clearance groove 230, the clamping member 310 can partially extend into the clearance groove 230 under the action of the spring. When the connecting member 110 moves along the clearance groove 230 to the clamping member 310, the connecting member 110 will squeeze the clamping member 310 extending into the clearance groove 230, so that the spring is compressed and force is accumulated. Under the continuous movement of the connecting member 110, the connecting member 110 will partially jump over the clamping member 310 to achieve clamping with the clamping member 310 (for example, it can be the cooperation between the clamping block 112 and the groove 231), and randomly fix the connecting member 110 and the clamping assembly 100 in the fixing seat 200.

[0074] The pressing member 320 is arranged on a side of the clamping member 310 different from the second elastic member, and the pressing member 320 and the clamping member 310 are connected by an inclined surface. When the clamping assembly 100 needs to be released from the fixing seat 200, an external force is applied to the pressing member 320, and the pressing member 320 applies force to the inclined surface between the clamping member 310 and the clamping member 310, so that a part of the force acting on the inclined surface is along the compression / extension direction of the second elastic member. In other words, the pressing member 320 can make the clamping member 310 move to the side away from the groove 231. When the clamping member 310 is completely moved into the installation cavity, the connecting member 110 connected thereto is released. At this time, the connecting member 110 is disengaged from the clearance groove 230 under the action of the push plate 410, that is, the clamping assembly 100 is disengaged from the fixing seat 200.

[0075] A more specific clamping method between the clamping member 310 and the connecting member 110 may be as follows: Figure 6 and Figure 7 As shown, in some embodiments, the clamping member 310 includes two clamping plates 311, which are respectively arranged on opposite sides of the clearance groove 230, and a clamping groove 3111 is configured on the side of the clamping plate 311 facing the clearance groove 230; the connecting member 110 includes a boss 111, and a clamping block 112 is configured on the side wall of the boss 111, and the clamping block 112 is used to be clamped in the clamping groove 3111.

[0076] Specifically, the two clamping plates 311 have the same structure and are symmetrically arranged on both sides of the clearance groove 230. In one example, one end of the second elastic member is limited to the side of the clamping plate 311 away from the clearance groove 230, and the other end is limited to the fixed seat 200. Specifically, there is a gap between the side of each clamping plate 311 away from the clearance groove 230 and the fixed housing 210, and the gap is used to install the second elastic member, i.e., a spring. For example, three springs can be arranged between the clamping plate 311 and the fixed housing 210 to maintain the stable movement of the clamping plate 311 relative to the clearance groove 230. Of course, two or more springs can also be arranged, and the specific number of springs is not limited here.

[0077] In order to achieve effective clamping between the clamping plate 311 and the connecting piece 110, a clamping groove 3111 is constructed on the side of the clamping plate 311 facing the yield groove 230. The clamping groove 3111 can be a notch formed by a protruding plate on the top of the clamping plate 311 and the side of the clamping plate 311, or it can be a groove formed by a protruding plate on the top of the clamping plate 311 and the two side walls, i.e., the side of the clamping plate 311. The card slot 3111 is used for the card block 112 in the connecting member 110 to enter. Specifically, after the card block 112 enters the clearance groove 230 along with the boss 111, the edge of the card block 112 first contacts the edge of the clamping plate 311 (the top plate). During the continuous movement of the card block 112, the card block 112 squeezes the clamping plate 311 into the installation cavity, causing the second elastic member to deform and accumulate force. During the continued movement of the card block 112, until the card block 112 completely enters the card slot 3111, since the diameter of the boss 111 is smaller than the diameter of the card block 112, the clamping plate 311 partially extends into the clearance groove 230 under the force of the second elastic member, and the card block 112 contacts the part of the clamping plate 311 located in the clearance groove 230 under the pressure of the push plate 410.

[0078] It should be noted that in order to facilitate the block 112 to squeeze the clamping plate 311 located in the make way groove 230 into the installation cavity, the edge where the block 112 contacts the clamping plate 311 is chamfered. Of course, the edge where the clamping plate 311 contacts the block 112 can also be chamfered. The chamfer can be a bevel chamfer or an arc chamfer, which is not limited here.

[0079] In addition, the side of the clamping plate 311 that abuts against the clamping block 112 is configured as an inclined surface. Figure 6 As shown in A, the side where the block 112 abuts against the clamping plate 311 is also set to an adaptive inclined surface. This setting can make the inclination angle of the contact inclined surface of the two smaller than the friction angle, thereby ensuring the stability when the clamping assembly 100 is locked to the fixed plate. In other words, if there is an external force that causes the connector 110 to escape along the clearance hole 232, friction (resistance) will be generated on the contact surface of the clamping plate 311 and the block 112, and as the external force increases, the resistance will also increase relatively, thereby realizing that the clamping plate 311 can also realize its self-locking function without being affected by the elastic force of the second elastic member, thereby avoiding the problem of the connector 110 escaping. The specific relationship between the inclination angle and the friction angle can be understood based on the relevant technology, and will not be repeated here.

[0080] like Figure 7 As shown, in some embodiments, the clamping plate 311 is provided with a guide surface 3112 on the side facing the yielding groove 230 , the guide surface 3112 is located on one side of the clamping groove 3111 , and the guide surface 3112 is used to contact with the push plate 410 .

[0081] It should be noted that, when the pressing member 320 is applied with force, the pressing member 320 will force the clamping plate 311 to move into the installation cavity, thereby releasing the clamping block 112, so that the connecting member 110 can be disengaged from the clearance groove 230 under the action of the push plate 410. The process in which the push plate 410 moves from the clearance groove 230 to the installation surface 240 under the force released by the first elastic member 420 is easily clamped by the clamping plate 311 inserted into the clearance groove 230, which not only cannot continue to provide the connecting member 110 with the power to push it out of the fixing seat 200, but also the push plate 410 cannot be reset to the installation surface 240, which brings unnecessary trouble to cleaning the fixing seat 200. Of course, the pressing member 320 can be re-applied to reset the push plate 410, but it will inevitably affect the user's experience.

[0082] like Figure 5 As shown, in some embodiments, a guide column 250 is provided in the installation cavity, and a positioning groove is configured on one side of the clamping plate 311 facing the clearance groove 230 , and the positioning groove is adapted to be plugged with the guide column 250 .

[0083] It is understandable that when the clamping assembly 100 switches between the locked state and the released state, it means that the clamping plate 311 reciprocates between the direction toward the clearance groove 230 and away from the clearance groove 230. In order to prevent the clamping member 310 from deflecting during the reciprocating movement, thereby affecting the reliability of the subsequent push plate 410 pushing the connecting member 110 to pop out, a guide column 250 is provided in the installation cavity, and a positioning groove adapted to the guide column 250 is configured on the side of the clamping plate 311 facing the clearance groove 230, so that the clamping member 310 reciprocates along a fixed direction (a direction perpendicular to the connecting member 110 entering the clearance groove 230) under the cooperation of the guide column 250 and the positioning groove.

[0084] In addition, the setting of the positioning column can also limit the distance that the clamping plate 311 extends into the clearance groove 230, so as to ensure that the end of the clamping plate 311 can smoothly enter the installation cavity after being squeezed by the above-mentioned clamping block 112, so as to form a clamping connection with the connecting member 110 later.

[0085] Of course, matching protrusions and positioning grooves may also be provided between one side wall, two side walls or the bottom surface of the clamping plate 311 and the fixed housing 210 to achieve the purpose of reciprocating movement of the clamping member 310 along the fixed direction.

[0086] like Figure 5 As shown, in some embodiments, the pressing member 320 includes two buttons, which are arranged relative to the clearance groove 230, and each button is arranged between the two clamping plates 311 and contacts the ends of the two clamping plates 311. The buttons are configured to apply force to the clamping plates 311 to move the clamping plates 311 away from the clearance groove 230.

[0087] It is understandable that in order to facilitate switching the clamping assembly 100 from the locked state to the released state and facilitate manual operation, two opposing buttons can be set on the fixed shell 210, and a portion of each button is exposed outside the fixed seat 200, so that it is convenient for people to apply force to the button. The side of each button facing the clearance groove 230 is set as an inclined surface. Similarly, the end of the clamping plate 311 in contact with the button is also set as an inclined surface. The setting of the inclined surface is convenient for one button to contact the end faces of the two clamping plates 311 at the same time, and on the other hand, it can provide a component force for pushing the clamping plate 311 to move. Moreover, the positions of the two buttons and the two clamping plates 311 are reasonably arranged, which is conducive to the miniaturization of the fixed seat 200.

[0088] like Figure 3 As shown, in some embodiments, the clamping assembly 100 also includes a main body and a buckle 120, the main body includes a first surface and a second surface relative to each other, the buckle 120 is arranged on the first surface, and the connecting member 110 is arranged on the second surface; the second surface is provided with a plurality of clamping plates 130, and in the locked state, the plurality of clamping plates 130 are clamped to the outside of the fixing seat 200.

[0089] Specifically, the buckle 120 is provided to facilitate fixing the ultrasonic probe, and the connector 110 is provided on a side opposite to the buckle 120, and can be locked on the fixing seat 200, so as to achieve the purpose of fixing the ultrasonic probe on the end of the mechanical arm 500, and will not affect the normal use of the ultrasonic probe. A plurality of clamping plates 130 are provided on the same side as the connector 110, so that in the process of locking the clamping assembly 100 on the fixing seat 200, the plurality of clamping plates 130 can form a guiding role with the fixing seat 200, so as to prevent the connector 110 from being offset when entering the clearance groove 230, and the plurality of clamping plates 130 are clamped outside the fixing seat 200, so as to maintain a stable connection between the clamping assembly 100 and the fixing seat 200, thereby ensuring the stability of the use of the ultrasonic probe.

[0090] The present application also provides an ultrasonic inspection device, such as Figure 1 and Figure 2 As shown, it may include a mechanical arm 500, a chuck 600 and the installation device of the ultrasonic probe in the above embodiment. Among them, the fixing seat 200 is fixedly connected to the end of the mechanical arm 500; the chuck 600 is clamped with the clamping assembly 100 to fix the sterile cover.

[0091] It is understandable that the end of the fixing seat 200 away from the mounting surface 240 can be fixedly connected to the end of the mechanical arm 500, for example, by bolt connection, joint connection, etc., which is not limited here. The chuck 600 is a hollow structure, and the edge is used to be clamped on the body of the above-mentioned clamping assembly 100, and the first surface of the body can be exposed to avoid or reduce the impact on the use of the ultrasonic probe.

[0092] Before using the ultrasonic inspection equipment, first wipe the mounting surface 240 of the fixing seat 200 and the upper surface of the push plate 410 clean, fix the clamping assembly 100 to the fixing seat 200, then put the sterile cover (sleeve-shaped) on the robot arm 500 and the fixing seat 200, and then fix the end of the sterile cover to the body of the clamping assembly 100 through the chuck 600, that is, the buckle 120 on the clamping assembly 100 can be exposed, and then fix the ultrasonic probe through the buckle 120.

[0093] Finally, it should be noted that the above implementation modes are only used to illustrate the present application, rather than to limit the present application. Although the present application is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should be included in the scope of the claims of the present application.
