[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0044] The core of the present invention is to provide an ultrasonic probe pressure regulating device, which can not only help doctors maintain the pressure between the ultrasonic probe and human skin, but also effectively reduce the burden of doctors' grip.
[0045] Please refer to Figures 1 to 5 , Figure 1This is a schematic diagram of the structure of the ultrasonic probe pressure regulating device provided by the present invention; Figure 2 A schematic diagram of the internal structure of the first shell and the second shell; Figure 3 is an exploded schematic diagram of the first shell; Figure 4 It is a schematic diagram of the structure of the limit strip and the second bearing seat; Figure 5 It is a schematic diagram of the structure of the lead screw and the universal shaft.
[0046] The present specific embodiment provides an ultrasonic probe pressure regulating device, comprising: a pressure detection mechanism 2, one end of which is provided with an ultrasonic probe 8, the pressure detection mechanism 2 is used to detect the pressure between the ultrasonic probe 8 and human skin; a screw assembly 3, which includes a screw 31 and a slider 32 sleeved on the outer periphery of the screw 31, and the other end of the pressure detection mechanism 2 is connected to the slider 32; a first shell 1, the pressure detection mechanism 2 and the screw assembly 3 are both arranged in the first shell 1; a rotating drive member 6; a second shell 5, the rotating drive member 6 is arranged in the second shell 5, and the second shell 5 is worn on the wrist of a physician; a universal shaft 4, one end of which is connected to the screw 31, and the other end of the universal shaft 4 is connected to the rotating drive member 6; a controller, the pressure detection mechanism 2 and the rotating drive member 6 are both connected to the controller, when the pressure detection mechanism 2 detects that the pressure between the ultrasonic probe 8 and the human skin deviates from the normal value, the controller controls the rotating drive member 6 to rotate, so as to drive the screw 31 to rotate through the universal shaft 4, and the slider 32 drives the pressure detection mechanism 2 to move, so that the pressure between the ultrasonic probe 8 and the human skin returns to the normal value.
[0047] It should be noted that the second housing 5 is worn on the physician's wrist, and the wearing method is similar to that of a watch. The present device sets the rotary drive member 6 and the ultrasonic probe 8 at both ends of the universal shaft 4, respectively, in order to help the physician maintain the pressure between the ultrasonic probe 8 and the human skin, while greatly reducing the physician's gripping burden compared to the ultrasonic probe 8 pressure adjustment device in the prior art. Moreover, the universal shaft 4 can be set as a soft universal shaft structure.
[0048] In actual use, the shape, structure, size, material, position, etc. of the pressure detection mechanism 2, the screw assembly 3, the first shell 1, the rotating drive member 6, the second shell 5, the universal shaft 4 and the controller can be determined according to actual conditions and actual needs.
[0049] When a doctor uses the ultrasonic probe pressure regulating device provided by the present invention, first, the second housing 5 can be worn on the wrist. Then, the ultrasonic probe 8 is attached to the human skin, and the pressure detection mechanism 2 can detect the pressure value between the ultrasonic probe 8 and the human skin. When the pressure value deviates from the normal value, the controller controls the rotation drive member 6 to rotate, and the rotation drive member 6 drives the lead screw 31 of the lead screw assembly 3 to rotate through the universal shaft 4. When the lead screw 31 rotates, it can drive the slider 32 to move along the axial direction of the lead screw 31. The slider 32 drives the pressure detection mechanism 2 to move, so that the pressure value between the ultrasonic probe 8 and the human skin returns to the normal value, thereby helping the doctor to maintain the pressure between the ultrasonic probe 8 and the human skin.
[0050] The structural setting of the device, on the one hand, makes the heavy rotary drive member 6 worn on the doctor's wrist, reducing the weight of the doctor's handheld part (the end with the ultrasonic probe 8). On the other hand, the first shell 1 and the second shell 5 are connected by the universal shaft 4, and the universal shaft 4 can form a certain pulling force on the first shell 1, further reducing the gravity of the doctor's handheld part and alleviating the burden of the doctor's grip.
[0051] In summary, the ultrasound probe pressure regulating device provided by the present invention can not only help doctors maintain the pressure between the ultrasound probe 8 and human skin, but also effectively reduce the burden on doctors to hold the device.
[0052] In one embodiment, Figure 1 and Figure 2 As shown, the first shell 1 includes a first body 11 and a first cover plate 12, and the second shell 5 includes a second body 51 and a second cover plate 52. The first body 11 and the second body 51 are both provided with a top opening. The first cover plate 12 covers the top opening of the first body 11, and the second cover plate 52 covers the top opening of the second body 51, so as to facilitate the installation of the pressure detection mechanism 2 and the screw assembly 3 into the first body 11, and also facilitate the maintenance and inspection of the pressure detection mechanism 2 and the screw assembly 3, and also facilitate the installation of the rotating drive member 6 into the second body 51, and also facilitate the maintenance and inspection of the rotating drive member 6.
[0053] In one embodiment, two guide bars 111 are arranged on the inner side of the bottom wall of the first body 11 and are arranged along the axial direction of the lead screw 31. The slider 32 is arranged between the two guide bars 111. The two guide bars 111 can prevent the slider 32 from rotating synchronously with the lead screw 31 of the lead screw assembly 3, and provide a guide for the slider 32 to slide.
[0054] In one embodiment, a first bearing seat 33 and a second bearing seat 34 are respectively provided at both ends of the screw 31, and bearings are provided in the first bearing seat 33 and the second bearing seat 34. The first bearing seat 33 is close to the universal joint 4, and the first bearing seat 33 is connected to the first body 11. The second bearing seat 34 is arranged in the first body 11 along the axial movement of the screw 31.
[0055] It should be noted that the connection between the first bearing seat 33 and the first body 11 may mean that the first bearing seat 33 and the first body 11 are an integrated structure, or the first bearing seat 33 and the first body 11 are connected by screws and other components. When the operator needs to install the lead screw 31 between the first bearing seat 33 and the second bearing seat 34, first, one end of the lead screw 31 can be inserted into the first bearing seat 33, and then the second bearing seat 34 can be sleeved on the outer periphery of the lead screw 31, so that the two ends of the lead screw 31 are clamped by the first bearing seat 33 and the second bearing seat 34 respectively, and finally the axial direction of the lead screw 31 is fixed, ensuring that the lead screw 31 only performs rotational movement. Moreover, the two guide bars 111 can clamp the second bearing seat 34, ensuring that the second bearing seat 34 can only reciprocate along the axial direction of the lead screw 31.
[0056] In one embodiment, a limiting strip 121 is disposed downwardly on the first cover plate 12 . When the first cover plate 12 is covered on the first body 11 , the limiting strip 121 is used to block the axial movement of the second bearing seat 34 .
[0057] It should be noted that a limiting strip 121 is integrally formed downwardly on the first cover plate 12, and when the first cover plate 12 is fixedly covered on the top of the first body 11, the limiting strip 121 can block the axial movement of the second bearing seat 34, thereby blocking the axial movement of the second bearing seat 34. That is, the limiting strip 121 is provided to limit the movement of the second bearing seat 34 along the axial direction of the lead screw 31.
[0058] In one embodiment, a wedge-shaped structure is provided at the bottom of the limit bar 121, the thickness of the bottom of the wedge-shaped structure is less than the thickness of the top of the wedge-shaped structure, and a slope matching the wedge-shaped structure is provided on the side of the second bearing seat 34 close to the limit bar 121. Therefore, when the limit bar 121 moves downward, it can form a certain pressure on the second bearing seat 34, so that the first bearing seat 33 and the second bearing seat 34 form a clamping effect on the lead screw 31.
[0059] In one embodiment, the bottom of the first cover plate 12 is provided with a plurality of positioning bosses 122, and the top of the first body 11 is provided with a plurality of positioning grooves 112 that are engaged with the positioning bosses 122. When the positioning bosses 122 and the positioning grooves 112 are engaged with each other, the limiting strip 121 and the second bearing seat 34 are aligned.
[0060] In addition, the engagement of the positioning boss 122 and the positioning groove 112 can also block the movement of the first cover plate 12 along the axial direction of the lead screw 31, provide a reaction force for the limit bar 121, and ensure that the limit bar 121 forms a good abutment against the second bearing seat 34. At the same time, in order to facilitate the fixation between the first cover plate 12 and the first body 11, the limit bar 121 can be fixed to the first body 11 by a screw 9, and the threaded end of the screw 9 penetrates the first body 11 and is threadedly connected to the limit bar 121, and the head of the screw 9 abuts against the bottom of the first body 11.
[0061] In one embodiment, two opposite sides of the second body 51 are provided with straps 7, and the free ends of the two straps 7 are detachably connected. For example, the free ends of the two straps 7 can be connected by Velcro or snaps.
[0062] It should be noted that, refer to Figure 1 Since the second cover plate 52 needs to fit the doctor's forearm, the second cover plate 52 can be set in an arc shape to improve comfort. Figure 1 In order to enable the second shell 5 to be worn on the doctor's wrist, straps 7 are fixed to the opposite sides of the second body 51, and the free ends of the two straps 7 are fixed by Velcro, snaps or other detachable means, making it more convenient for the doctor to wear the second shell 5.
[0063] In one embodiment, Figure 2 As shown, the pressure detection mechanism 2 includes a first connecting plate 21, a pressure sensor 22 connected to a controller, and a second connecting plate 23. The ultrasonic probe 8 is arranged on one side of the first connecting plate 21. The pressure sensor 22 is arranged between the other side of the first connecting plate 21 and one side of the second connecting plate 23. The other side of the second connecting plate 23 is connected to a slider 32. The pressure between the ultrasonic probe 8 and the human skin is transmitted to the pressure sensor 22 through the first connecting plate 21, and the slider 32 drives the movement of the ultrasonic probe 8 through the second connecting plate 23, thereby adjusting the pressure between the ultrasonic probe 8 and the human skin.
[0064] It should be noted that, in order to realize the connection between the ultrasonic probe 8 and the first connecting plate 21, a buckle is fixed on the first connecting plate 21, and both ends of the buckle are fixed to the first connecting plate 21 by screws 9. The ultrasonic probe 8 is clamped and fixed to the first connecting plate 21 by the buckle, so as to fix the ultrasonic probe 8 on the first connecting plate 21. Of course, in actual use, according to actual conditions and actual needs, other methods and structures can be used to fix the ultrasonic probe 8 on the first connecting plate 21.
[0065] In one embodiment, Figure 5As shown, a connecting groove 311 is provided at one end of the lead screw 31 , and a connecting piece 41 for inserting into the connecting groove 311 is provided at one end of the universal shaft 4 , and the connecting piece 41 and the connecting groove 311 are fixedly connected by a connecting piece.
[0066] It should be noted that in order to achieve the connection between the screw 31 and the universal shaft 4, a connecting groove 311 is opened at one end of the screw 31 adjacent to the universal shaft 4, and a connecting piece 41 is integrally formed at one end of the universal shaft 4. The connecting piece 41 is inserted into the connecting groove 311, and then the connecting piece 41 is fixed to the end of the screw 31 through a connecting member (screw 9) (for example, a threaded hole is vertically penetrated through the connecting groove 311, and a threaded hole is correspondingly penetrated through the connecting piece 41, and the screw 9 passes through the threaded holes aligned with the connecting groove 311 and the connecting piece 41 to lock the connecting groove 311 and the connecting piece 41), so that the connection between the universal shaft 4 and the end of the screw 31 is more convenient and quick.
[0067] It should be supplemented that a mounting seat 511 can be fixedly provided in the second body 51, and the rotary drive member 6 is fixed in the second body 51 through the mounting seat 511. In this solution, the rotary drive member 6 is preferably a stepper motor. Of course, in other solutions, the rotary drive member 6 can also be other rotary drive structures such as a servo motor. The rotating shaft of the stepper motor and the end of the universal shaft 4 are coaxially fixed through a coupling. Compared with the ultrasonic probe 8 pressure adjustment device in the prior art, this device can greatly reduce the burden of the doctor's grip while helping the doctor maintain the pressure between the ultrasonic probe 8 and the human skin. Moreover, through simulation and experiments, it can be known that this device can indeed achieve the effect of helping the doctor maintain the pressure between the ultrasonic probe 8 and the human skin while reducing the burden of the doctor's grip.
[0068] It should be noted that the first shell 1 and the second shell 5, the first body 11 and the second body 51, the first cover plate 12 and the second cover plate 52, the first bearing seat 33 and the second bearing seat 34, the first connecting plate 21 and the second connecting plate 23 mentioned in the present invention, where the first and the second are just to distinguish the different positions, and there is no order of precedence.
