[0032] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0033] Reference Figure 1-Figure 10 The present application provides an ultrasonic probe, including a shell 1 provided with a storage space 13 and a probe body 2 slidably connected to the shell 1, the scanning end of the probe body 2 extends out of the storage space 13, and a clamping assembly 3 suitable for preventing the probe body 2 from sliding is provided between the probe body 2 and the shell 1. The clamping assembly 3 includes a first clamping member 31 and a second clamping member 32 that are clamped to each other. The second clamping member 32 is slidably arranged in the shell 1. When the ultrasonic probe is in a power-on state, the second clamping member 32 slides to be clamped with the first clamping member 31. When the ultrasound probe is in a power-off state, the second clamping member 32 slides to be separated from the first clamping member 31.

[0034] When the above-mentioned ultrasound probe encounters an emergency power outage during automatic scanning, the second clamping component 32 slides to separate from the first clamping component 31, and the clamping assembly 3 no longer restricts the sliding of the probe body 2. As the robotic arm continues to move forward under the action of inertia, the probe body 2 will slide away from the human body due to the reaction force of the human body, thereby avoiding injury to the patient.

[0035] In some embodiments, reference Figure 1-Figure 10 The first clamping member 31 is connected to the side of the probe body 2 facing the shell 1, and a clamping groove 3111 is provided on the first clamping member 31. The second clamping member 32 is slidably connected to the shell 1, and a first protrusion 323 for clamping with the clamping groove 3111 is provided on the second clamping member 32. A pushing component 4 is connected to the shell 1 for pushing the second clamping member 32 to slide so that the second clamping member 32 is clamped or separated from the first clamping member 31.

[0036] When the ultrasonic probe is in a powered-on state, the second clamping member 32 is pushed by the component 4 to slide until the first protrusion 323 is engaged in the slot 3111 on the first clamping member 31, thereby preventing the ultrasonic probe from sliding. When the ultrasonic probe is in a powered-off state, the second clamping member 32 is pushed by the component 4 to slide until the first protrusion 323 is separated from the slot 3111 of the first clamping member 31, thereby allowing the probe body 2 to slide in the accommodating space 13.

[0037] In some embodiments, reference Figure 1 and Figure 2 The housing 1 includes an upper housing 11 and a lower housing 12 connected to each other, the upper housing 11 and the lower housing 12 are connected to each other to form a receiving space 13, the second clamping member 32 is connected to a side of the lower housing 12 facing the classroom and is located in the receiving space 13, and the first clamping member 31 is connected to a side of the probe body 2 located in the receiving space 13 and facing the lower housing 12. Dividing the housing 1 into the upper housing 11 and the lower housing 12 connected to each other facilitates the assembly of the clamping assembly 3, thereby facilitating the assembly of the ultrasound probe.

[0038] In some embodiments, reference Figure 1-Figure 10 A limiting cover 5 is provided on the side of the lower shell 12 facing the probe body 2, and the opening of the limiting cover 5 is set toward the lower shell 12. The second clamping member 32 is slidably arranged in the limiting cover 5. A first through hole 51 for the first protrusion 323 to extend out is provided on the side wall of the limiting cover 5. A second protrusion 311 is provided on the side of the first clamping member 31 facing the lower shell 12. The second protrusion 311 is located on the side of the limiting cover 5. A slot 3111 is opened on the side of the second protrusion 311 facing the limiting cover 5. The second clamping member 32 slides to make the first protrusion 323 extend out of the first through hole 51 and engage with the slot 3111.

[0039] The limiting cover 5 allows the second clamping member 32 to move only toward the slot 3111 or away from the slot 3111. After the second clamping member 32 moves a certain distance toward the slot 3111, the first protrusion 323 extends from the first through hole 51 and engages with the slot 3111 on the second protrusion 311, thereby preventing the probe body 2 from sliding along its own length direction, so that the ultrasonic probe can work stably when powered on.

[0040] In some embodiments, reference Figure 2-Figure 10 The second connector 32 includes a first connector 321 and a second connector 322 which are slidably connected in the limit cover 5, and the first protrusion 323 is arranged on a side of the first connector 321 facing the first through hole 51. The first connector 321 is slidably inserted in the second connector 322 so that the first connector 321 can only move in the direction close to or away from the slot 3111. The pushing component 4 is used to push the first connector 321 to slide in the direction of the slot 3111 so that the first protrusion 323 extends out of the first through hole 51 and is engaged with the slot 3111, or is used to push the first connector 321 to slide in the direction away from the slot 3111 so that the first protrusion 323 slides into the first through hole 51 and is separated from the slot 3111.

[0041] The first plug-in component 321 is slidably inserted into the second plug-in component 322, so that the pushing component 4 can only push the first plug-in component 321 to move toward or away from the card slot 3111, thereby limiting the sliding direction of the first plug-in component 321. Figure 5-Figure 7 The first protrusion 323 moves along the width direction of the probe body 2 so that it can be engaged with the slot 3111, and the second connector 322 is provided with a slot 3221 on the side facing the first connector 321, and the first connector 321 is provided with a plug block 3211 slidably inserted in the slot 3221 on the side facing the second connector 322, and the two side walls of the first connector 321 away from the end of the second connector 322 are slidably connected with the side walls of the limiting cover 5, and the two sides of the second connector 322 are slidably connected with the side walls of the limiting cover 5. Such a design limits the position of the second connector 322 so that it cannot move in the length direction of the probe body 2, and also makes the first connector 321 only slide in a direction perpendicular to the length direction of the probe body 2, so that the first protrusion 323 can accurately engage with the slot 3111 or be retracted into the limiting cover 5 through the first through hole 51.

[0042] In some embodiments, reference Figure 2-Figure 10 There are two second protrusions 311, which are respectively located on both sides of the limiting cover 5 along the width direction of the probe body 2, and a groove 3111 is provided on the opposite side of the two second protrusions 311. The first connector 321 and the second connector 322 are both provided with a first protrusion 323. The two side walls of the limiting cover 5 are both provided with a first through hole 51 corresponding to the first protrusion 323. The pushing component 4 pushes the first connector 321 and the second connector 322 away from each other so that the first protrusions 323 on the two connectors are respectively engaged with the corresponding grooves 3111 or pushes the first connector 321 and the second connector 322 close to each other so that the first protrusions 323 on the two connectors are respectively separated from the corresponding grooves 3111. By providing first protrusions 323 on both the first connector 321 and the second connector 322, the two first protrusions 323 can be respectively engaged with the slots 3111 on both sides of the limit cover 5, thereby improving the scanning stability of the probe body 2 when the ultrasonic probe is powered on, and reducing the possibility of sliding of the probe body 2 in the powered on state. The pushing component 4 can push the first connector 321 to slide in a direction perpendicular to the length direction of the probe body 2 so as to move away from or approach each other. The first connector 321 and the second connector 322 move away from each other, which can make the two first protrusions 323 slide toward the corresponding first through hole 51 respectively and engage with the corresponding slots 3111 therewith. The first connector 321 and the second connector 322 move closer to each other, which can make the two first protrusions 323 respectively disengage from the corresponding slots 3111 and make the sliding of the probe body 2 in the direction of its own length direction no longer restricted.

[0043] In some embodiments, reference Figure 2-Figure 10The pushing assembly 4 includes a sliding portion 42 slidably connected to the lower shell 12, and the sliding portion 42 slides along the length direction of the probe body 2. Two sliding grooves 421 are provided on the sliding portion 42, and one end of the two sliding grooves 421 gradually approaches along the direction away from the scanning end of the probe body 2. A first slider 3212 is provided on the side of the first connector 321 facing away from the probe body 2, and a second slider 3222 is provided on the side of the second connector 322 facing away from the probe body 2. The first slider 3212 and the second slider 3222 are respectively slidably connected in the two sliding grooves 421 of the sliding portion 42. When the first slider 3212 and the second slider 3222 slide in the direction away from the scanning end of the probe body 2, the first connector 321 and the second connector 322 move away from each other. When the first slider 3212 and the second slider 3222 slide in the direction toward the scanning end of the probe body 2, the first connector 321 and the second connector 322 approach each other. By providing the two sliding grooves 421 on the sliding portion 42 , the first connector 321 and the second connector 322 can slide synchronously in the limiting cover 5 , so as to move away from or approach each other.

[0044] In some embodiments, reference Figure 2-Figure 10 A fixed seat 6 is provided on one side of the lower shell 12 facing the upper shell 11, a limiting cover 5 is located above the fixed seat 6, a sliding portion 42 is slidably connected to the fixed seat 6, and the pushing assembly 4 further includes a pushing member 43 for pushing the sliding portion 42. By pushing the pushing member 43, the sliding portion 42 can slide on the fixed seat 6 along the length direction of the probe body 2.

[0045] In some embodiments, reference Figure 2-Figure 10 The fixed seat 6 is provided with a first groove 61 on one side facing the probe body 2. The pusher 43 is a push-pull electromagnet, which is fixed in the first groove 61. A sliding seat 41 is slidably provided in the first groove 61. The sliding portion 42 is fixed on the sliding seat 41. The movable end of the push-pull electromagnet is fixedly connected to the sliding seat 41. After the ultrasonic probe is powered on, the push-pull electromagnet pulls the sliding seat 41 to move in a direction away from the scanning end of the probe body 2. After the ultrasonic probe is powered off, the push-pull electromagnet pushes the sliding seat 41 to move in a direction close to the scanning end of the probe body 2. The push-pull electromagnet pulls the sliding seat 41 to move in a direction away from the scanning end of the probe body 2, so that the first connector 321 and the second connector 322 are separated from each other so that the first protrusion 323 is engaged with the slot 3111. The push-pull electromagnet pushes the sliding seat 41 to move in a direction close to the scanning end of the probe body 2 so that the first protrusion 323 is separated from the slot 3111. The push-pull electromagnet pushes the sliding seat 41 to move in a direction close to the scanning end of the probe body 2 so that the first protrusion 323 is separated from the slot 3111.

[0046] Specifically, refer to Figure 2-Figure 10The push-pull electromagnet is fixed at one end of the first groove 61 away from the scanning end of the probe body 2, and the fixed seat 6 is slidably connected to the end of the first groove 61 close to the scanning end of the probe body 2. The width of the first groove 61 where the fixed seat 6 is located is smaller than the width of the first groove 61 where the push-pull electromagnet is located, so that the side wall of the first groove 61 where the fixed seat 6 is located can be slidably connected with the side wall of the sliding seat 41, thereby playing a certain guiding role and reducing the possibility of deflection of the sliding seat 41 when sliding.

[0047] In some embodiments, reference Figure 2-Figure 10 , the probe body 2 is slidably connected in the accommodating space 13 through the sliding assembly 7, a connecting seat 8 is fixed on the lower shell 12, the connecting seat 8 is located above the fixing seat 6, the limiting cover 5 is fixed on the side of the connecting seat 8 facing away from the fixing seat 6, the limiting cover 5 is located above the connecting seat 8, and a second through hole 81 for accommodating the sliding part 42 is provided on the connecting seat 8, the limiting cover 5 is located above the second through hole 81 and is connected to the second through hole 81. Specifically, the shape of the second through hole 81 is similar to that of the first groove 61, and the width of a section of the second through hole 81 opposite to the limiting cover 5 is slightly widened to leave enough space for the sliding of the first slider 3212 and the second slider 3222. In addition, the sliding part 42 is located outside the first groove 61, and the second through hole 81 is used to avoid the sliding part 42 and the push-pull electromagnet higher than the first groove 61.

[0048] In some embodiments, reference Figure 2-Figure 10 The sliding assembly 7 includes a sliding rod 71 arranged on the connecting seat 8 and a sliding member 72 fixed on the probe body 2, and the sliding member 72 is slidably mounted on the sliding rod 71. Specifically, two sliding rods 71 ​​are provided, and the two sliding rods 71 ​​are respectively close to the two sides of the connecting seat 8 along the width direction of the probe body 2, and two sleeve holes 721 are provided on the sliding member 72, and the two sleeve holes 721 are respectively located on the two sides of the probe body 2, and the two sleeve holes 721 are respectively slidably mounted on the two sliding rods 71. Through the sliding cooperation of the two sliding rods 71 ​​and the sleeve holes 721, the probe body 2 is subjected to more uniform force during the sliding process, the possibility of mutual wear between the sliding rod 71 and the sliding member 72 is reduced, and the friction force when the probe body 2 slides is reduced, thereby improving the smoothness of the sliding of the probe body 2.

[0049] In some embodiments, reference Figure 8-Figure 10A third protrusion 82 is provided on the side of the connecting seat 8 facing away from the shell, and the probe body 2 includes a scanning portion 21 and a connecting portion 22 connected to each other. The thickness of the scanning portion 21 is greater than the thickness of the connecting portion 22. The third protrusion 82 is opposite to the scanning portion 21, and a fixing column 211 is provided on the side of the scanning portion 21 facing the third protrusion 82. A socket 821 for slidingly inserting the fixing column 211 is provided on the side of the third protrusion 82 facing the scanning portion 21. An elastic member 9 is connected between the fixing column 211 and the third protrusion 82, one end of the elastic member 9 is fixedly sleeved on the fixing column 211, and the other end of the elastic member 9 is fixed in the socket 821 of the third protrusion 82. When the elastic member 9 is compressed, the probe body 2 moves toward the direction of the third protrusion 82. The setting of the socket 821 increases the distance that the probe body 2 can move. When the ultrasound probe is in a power-off state, the clamping assembly 3 no longer restricts the sliding of the probe body 2 along the length direction of the probe body 2 itself, and the probe body 2 compresses the elastic member 9 and slides in the direction of the third protrusion 82, which can prevent the patient from being squeezed by the ultrasound probe and injured. After the patient leaves, the probe body 2 returns to its original position under the action of the elastic member 9. At this time, if the ultrasound probe is powered on, the clamping assembly 3 can be re-clamped to restrict the sliding of the probe body 2. Specifically, the elastic member 9 is a spring.

[0050] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
