[0028] The present invention provides an animal fixing device 100 and an animal detector 10, which are used to fix the body and head of an animal during an ultrasonic examination. The animal fixing device 100 and the animal detector 10 provided by the present invention can be used to fix the body and head of various animals. For ease of description, the following content takes primates (such as monkeys, gorillas, etc.) as an example to illustrate the animal fixing device 100 and the animal detector 10 provided by the present invention.

[0029] like Figure 1As shown, an embodiment of the present invention provides an animal fixing device 100, which includes a head fixing component 110 and a body fixing component 130. The head fixing component 110 is used to fix the head of the animal, and the body fixing component 130 is used to fix the body of the animal. There are multiple connection positions 1311 between the body fixing component 130 and the head fixing component 110 in the direction in which the animal's body extends. When the connection position 1311 between the body fixing component 130 and the head fixing component 110 changes, the body fixing component 130 approaches or moves away from the head fixing component 110 along the extension direction of the animal's body. The above-mentioned animal fixing device 100, the body fixing component 130 and the head fixing component 110 can adjust the relative position along the extension direction of the animal body through a plurality of connection positions 1311 therebetween. When the animal is slightly smaller, the distance between the body fixing component 130 and the head fixing component 110 can be shortened. When the animal is larger, the distance between the body fixing component 130 and the head fixing component 110 can be increased, thereby achieving effective fixation of animals of different sizes, thereby enhancing the adaptability of the animal fixing device 100 and the animal detector 10 to actual inspection conditions.

[0030] Optionally, the multiple connection positions 1311 between the head fixing component 110 and the body fixing component 130 are continuous connection positions 1311 or spaced connection positions 1311. When the connection positions 1311 are continuous connection positions 1311, the relative position between the head fixing component 110 and the body fixing component 130 along the extension direction of the animal's body can be continuously adjusted. When the connection positions 1311 are spaced connection positions 1311, the body fixing component 130 has a set relative position option relative to the head fixing component 110. In one embodiment of the present invention, the multiple connection positions 1311 between the head fixing component 110 and the body fixing component 130 are continuous connection positions 1311, which realizes stepless adjustment of the relative position between the body fixing component 130 and the head fixing component 110. As a feasible method, a fixing hole is provided on the head fixing component 110, and a strip hole is provided on the body fixing component 130, the strip hole extends in the direction in which the animal's body extends, and the fixing hole cooperates with the strip hole to form a continuous connection position 1311 in the direction in which the animal's body extends, and the fixing hole is fixedly connected to any position of the strip hole by a fastener (such as a bolt, a screw, a clip, etc.). The connection method of the strip hole, the fixing hole and the fastener has the advantages of simple structure and stable operation, and effectively ensures the fixing efficiency of the animal fixing device 100 when fixing animals of different sizes.

[0031] Further, if Figure 1As shown, there is also a sliding guide structure between the head fixing component 110 and the body fixing component 130, for example, a slide groove 1111 is provided on the head fixing component 110 along the extension direction of the animal's body, and a part of the body fixing component 130 is slidably matched with the slide groove 1111 to achieve stable position adjustment between the body fixing component 130 and the head fixing component 110. In other embodiments, the relative position relationship between the head fixing component 110 and the body fixing component 130 can also be adjusted by a bolt matching a threaded hole, for example, a threaded hole is provided on the head fixing component 110, one end of the bolt is rotatably installed on the body fixing component 130, and the bolt and the body fixing component 130 are relatively fixed in the extension direction of the animal's body, and when the bolt is rotated, the body fixing component 130 approaches or moves away from the head fixing component 110.

[0032] The function of the body fixing assembly 130 is to fix the body part of the animal during the animal examination. Figure 1 As shown, the body fixing assembly 130 includes a body base plate 131, a body support plate 132 and two body splints 133. The body base plate 131 can be directly placed on the bearing plane, and the body support plate 132 can be raised and lowered on the body base plate 131 in the vertical direction, and the body support plate 132 is used to carry the body of the animal to be fixed. The liftable body support plate 132 can drive the animal's body to rise or fall within a set range according to the animal's body shape and the actual detection working conditions, further improving the adaptability of the animal fixing device 100 provided in this embodiment to the actual detection working conditions. The two body splints 133 are respectively arranged on both sides of the body support plate 132 along the extension direction of the animal's body, at least one body splint 133 can move in a direction perpendicular to the extension direction of the animal's body, and at least one body splint 133 moves close to or away from another body splint 133 when moving, fully ensuring that fat or thin animals can be clamped.

[0033] As an achievable method, there are multiple connection positions 1311 between the body bottom plate 131 and the head fixing assembly 110 in the direction in which the animal body extends, and a strip hole is opened at one end of the body bottom plate 131 close to the head fixing assembly 110. Further, one end of the body bottom plate 131 close to the head fixing assembly 110 is slidably matched with the slide groove 1111 of the head fixing assembly 110. In one embodiment of the present invention, Figure 1As shown, two body splints 133 are movably arranged on the body support plate 132, and two spaced splint guide posts 134 are respectively arranged on the two side surfaces of the two body splints 133 that are away from each other, and the body support plate 132 has guide holes corresponding to the splint guide posts 134. The body fixing assembly 130 also includes a clamping screw 135, which can be pressed against the splint guide posts 134 through a threaded hole that passes through the guide hole. The splint guide posts 134 ensure that the body splints 133 slide smoothly in a direction perpendicular to the extension direction of the animal body, and the clamping screw 135 can fix the splint guide posts 134 at any position.

[0034] In one embodiment of the present invention, Figure 1 As shown, a plurality of vertical support plate guide posts 136 are arranged on the top surface of the body base plate 131, and a plurality of guide holes corresponding to the support plate guide posts 136 are provided on the body support plate 132, and the support plate guide posts 136 ensure the lifting stability of the body support plate 132 in the vertical direction. The lifting and lowering of the body support plate 132 relative to the body base plate 131 is realized by means of a screw rod and a connecting rod 137. When the screw rod is pulled into the position between the middle nodes of the connecting rod, the body support plate 132 rises in the vertical direction. When the screw rod is stretched to the position between the middle nodes of the connecting rod, the body support plate 132 falls in the vertical direction. The self-locking performance of the screw rod itself also ensures that the body support plate 132 can be stabilized at the adjusted height. In other embodiments, the lifting and lowering of the body support plate 132 can also be realized by means of a screw slider between the body base plate 131 and the body support plate 132. Further, the body support plate 132 has an arc segment adapted to the animal body in a direction perpendicular to the extension direction of the animal body, and the arc segment can adapt to the curvature of the animal body. As a feasible method, the body support plate 132 has an overall curvature along a direction perpendicular to the extension direction of the animal body. Air holes can also be provided on the body support plate 132 to ensure air permeability of the animal's body surface.

[0035] The function of the head fixing assembly 110 is to fix the head of the animal during the animal inspection. Figure 1As shown, the head fixing assembly 110 includes a head base plate 111, an ear fixing structure 112 and a jaw fixing structure 113. The ear fixing structure 112 and the jaw fixing structure 113 are respectively arranged on the base plate. The ear fixing structure 112 is used to be inserted into the ear of the animal along the direction of the line connecting the two ears of the animal, and the jaw fixing structure 113 is used to press against the lower jaw of the animal. The head of the animal is fixed by the ears and the lower jaw, which is simple, effective and has high fixing efficiency. As a feasible method, the head base plate 111 and the body base plate 131 are placed together on a bearing plane. There are multiple connection positions 1311 between the head base plate 111 and the body fixing assembly 130 in the direction in which the animal's body extends, that is, the fixing holes and the slide grooves 1111 on the head fixing assembly 110 are respectively opened on the head base plate 111.

[0036] In one embodiment of the present invention, Figure 1 As shown, the ear fixing structure 112 includes two ear fixing rods 1121 and two ear bars 1122, the ear fixing rods 1121 extend in the vertical direction, the bottom end of the ear fixing rods 1121 is fixedly arranged on the head bottom plate 111, and the two ear fixing rods 1121 are arranged at intervals along the direction of the line connecting the two ears of the animal. The two ear bars 1122 are respectively arranged at the top of an ear fixing rod 1121 along the direction of the line connecting the two ears of the animal, and the ear bars 1122 are inserted into or avoid the ears of the animal when they move along the direction of the line connecting the two ears of the animal. It can be understood that when the two ear bars 1122 are respectively inserted into the ears of the animal, the two ear bars 1122 move in a direction close to each other, and when the two ear bars 1122 avoid the ears of the animal, the two ear bars 1122 move in a direction away from each other. Further, a scale line is engraved on each ear bar 1122, which can accurately judge the depth of the ear bar 1122 inserted into the ear, ensuring effective fixation of the animal's head while avoiding damage to the animal's ears.

[0037] In one embodiment of the present invention, Figure 1 As shown, the jaw fixing structure 113 includes a jaw supporting plate 1131, a jaw guiding column 1132 and a jaw screw 1133. The jaw screw 1133 drives the jaw supporting plate 1131 to rise or fall relative to the head bottom plate 111 in the vertical direction. The jaw guiding column 1132 is arranged in the vertical direction, and the jaw guiding column 1132 is used to guide the jaw supporting plate 1131 to rise and fall in the vertical direction. The jaw guiding column 1132 and the jaw screw 1133 respectively realize the smooth lifting and labor-saving and stable lifting of the jaw supporting plate 1131. Further, the jaw fixing structure 113 also includes a jaw bottom plate 1134. The jaw guide column 1132 and the jaw screw 1133 are respectively arranged on the jaw bottom plate 1134, and the jaw bottom plate 1134 is fixedly mounted on the head bottom plate 111. Adding the jaw bottom plate 1134 can make the jaw fixing structure 113 into a whole, which is convenient for disassembly and installation.

[0038] like Figure 1 and Figure 2 As shown, an embodiment of the present invention further provides an animal detector 10, comprising a transducer adjustment device 300 and an animal fixing device 100 as described in any one of the above schemes. The animal fixing device 100 is used to fix the body and head of the animal to be detected, the transducer adjustment device 300 is used to adjust the orientation of the transducer 20 relative to the animal's head, and the detection head adjustment device is fixedly connected to the animal fixing device 100. In the above-mentioned animal detector 10, the body fixing component 130 and the head fixing component 110 can adjust the relative position along the extension direction of the animal's body through a plurality of connection positions 1311 therebetween. When the animal's body size is slightly smaller, the distance between the body fixing component 130 and the head fixing component 110 can be reduced. When the animal's body size is larger, the distance between the body fixing component 130 and the head fixing component 110 can be increased, thereby achieving effective fixation of animals of different body sizes, and enhancing the adaptability of the animal fixing device 100 and the animal detector 10 to actual inspection conditions. As an implementable manner, the transducer adjustment device 300 is installed on the head base plate 111, and the transducer 20 is mainly used to detect or treat the head of the animal.

[0039] Optionally, the transducer adjustment device 300 adjusts the transducer 20 by adjusting the position or the angle, or adjusts the position and the angle of the transducer 20 at the same time. Figure 1 and Figure 2 As shown, the transducer adjustment device 300 includes a translation adjustment component 310 and a rotation adjustment component 330. One end of the translation adjustment component 310 is fixedly connected to the animal fixing device 100, and the rotation adjustment component 330 is arranged at the other end of the translation adjustment component 310. The rotation adjustment component 330 can be installed with the transducer 20. The translation adjustment component 310 can drive the transducer 20 to translate, and the rotation adjustment component 330 can drive the transducer 20 to rotate. In this embodiment, one end of the translation adjustment component 310 is fixed on the head bottom plate 111, so that the integrity of the transducer adjustment device 300 and the animal fixing device 100 is achieved.

[0040] The translation adjustment component 310 can drive the transducer 20 to translate in one or more dimensions of space. As an achievable method, Figure 1 and Figure 2As shown, the translation adjustment assembly 310 includes a translation seat, a translation block, a translation screw and a translation guide column. The translation guide column is fixedly arranged on the translation seat. The translation guide column has a scale line along its own extension direction. The translation block is slidably arranged on the translation guide column. The rotation adjustment assembly 330 is arranged on the translation slider. One end of the translation screw is rotatably arranged on the translation seat. The translation screw is threadedly connected with the translation block. When the translation screw rotates, it drives the translation block to move along the extension direction of the translation guide column, and then the rotation adjustment assembly 330 and the transducer 20 also move along the extension direction of the translation guide column. The structural form of the translation seat, the translation block, the translation screw and the translation guide column not only realizes the smooth translation of the transducer 20, but also has the advantages of simple structure and easy adjustment. Further, the number of the translation guide columns can be two, three or more, so as to further ensure the smooth translation of the transducer 20. In other implementations, the translation adjustment component 310 may also be a structure in the form of a motor-driven belt. This embodiment does not specifically limit the specific structural form of the translation adjustment component 310.

[0041] It can be understood that the translation adjustment component 310 can drive the transducer 20 to perform one-dimensional translation, two-dimensional translation, or three-dimensional translation in space. As an achievable method, Figure 1 and Figure 2 As shown, the translation adjustment component 310 can drive the transducer 20 to perform translation in three dimensions in space. The translation adjustment component 310 includes a horizontal transverse adjustment structure 311, a horizontal longitudinal adjustment structure 312, and a vertical direction adjustment structure 313. The horizontal transverse adjustment structure 311 is used to adjust the position of the transducer 20 along the horizontal transverse direction, the horizontal longitudinal adjustment structure 312 is used to adjust the position of the transducer 20 along the horizontal longitudinal direction, and the vertical direction adjustment structure 313 is used to adjust the position of the transducer 20 along the vertical direction. The horizontal transverse direction, the horizontal longitudinal direction and the vertical direction are perpendicular to each other in the spatial orientation. The horizontal transverse adjustment structure 311 is fixedly arranged on the animal fixing device 100, the vertical direction adjustment structure 313 is arranged on the horizontal transverse adjustment structure 311, the horizontal longitudinal adjustment structure 312 is arranged on the vertical direction adjustment structure 313, and the rotation adjustment component 330 is arranged on the horizontal longitudinal adjustment structure 312.

[0042] Optionally, in the above embodiment, the horizontal longitudinal direction is the same as the extension direction of the animal body, the horizontal transverse direction is the same as the direction in which the two body splints 133 are spaced apart, and the vertical direction is the same as the direction in which the body support plate 132 is lifted and lowered, and the horizontal transverse adjustment structure 311 is fixedly arranged on the head bottom plate 111. Further, the translation structure of each dimension includes a corresponding translation seat, a translation block, a translation screw and a translation guide column, that is, the horizontal transverse adjustment structure 311 includes a transverse seat, a transverse block, a transverse screw and a transverse guide column, the horizontal longitudinal adjustment structure 312 includes a longitudinal seat, a longitudinal block, a longitudinal screw and a longitudinal guide column, and the vertical direction adjustment structure 313 includes a vertical seat, a vertical block, a vertical screw and a vertical guide column. The transverse seat is fixedly mounted on the head bottom plate 111, the vertical seat is fixedly mounted on the horizontal block and moves horizontally with the horizontal block, the longitudinal seat is mounted on the vertical block and moves vertically with the vertical block, and the rotation adjustment component 330 is fixedly mounted on the longitudinal block and moves horizontally and longitudinally with the longitudinal block. As a feasible manner, the vertical seat and the transverse block are integrally arranged, the longitudinal seat and the vertical block are integrally arranged, and the rotation adjustment component 330 and the longitudinal block are integrally arranged, which further simplifies the structure of the transducer adjustment device 300 .

[0043] It is understandable that the rotation adjustment assembly 330 can drive the transducer 20 to rotate in one dimension, two dimensions, or three dimensions in space. As an achievable method, Figure 1 and Figure 2 As shown, the rotation adjustment assembly 330 can drive the transducer 20 to rotate in two dimensions in space. The rotation adjustment assembly 330 includes a rotating seat 331, a first rotating frame 332 and a second rotating frame 333. The rotating seat 331 is fixedly arranged on the longitudinal block of the translation adjustment assembly 310. The first rotating frame 332 is rotatably arranged on the rotating seat 331. The first rotating frame 332 can rotate around a horizontal longitudinal axis relative to the rotating seat 331. The second rotating frame 333 is rotatably arranged on the first rotating frame 332. The second rotating frame 333 can rotate around a vertical axis relative to the first rotating frame 332. The second rotating frame 333 can install the transducer 20. The rotation in two dimensions can drive the transducer 20 to accurately rotate to a state corresponding to the position of the animal's head to be detected or treated.

[0044] The rotation of the rotation adjustment component 330 is driven directly by the operator or by the operator through the driving structure, or the rotation of the rotation adjustment component 330 is driven by the automatic driving mechanism. Figure 1 and Figure 2As shown, the rotation adjustment assembly 330 also includes a first turbine 334, a first worm 335, a second turbine 336 and a second worm 337. The first worm 335 is rotatably disposed on the rotating seat 331, the first turbine 334 is fixedly disposed on the first rotating frame 332, the first worm 335 is meshed with the first turbine 334, and when the first worm rotates, the first rotating frame 332 is driven to rotate by the first turbine 334. The second worm 337 is rotatably disposed on the first rotating frame 332, the second turbine 336 is fixedly disposed on the second rotating frame 333, the second worm 337 is meshed with the second turbine 336, and when the second worm rotates, the second rotating frame 333 is driven to rotate by the second turbine 336. The use of the turbine and worm structure as the driving structure of the rotation adjustment assembly 330 not only realizes the smooth rotation of the rotation adjustment assembly, but also the self-locking characteristics of the turbine and worm can keep the rotation adjustment assembly 330 at any rotation angle. Furthermore, angle lines are respectively engraved on the first rotating frame 332 and the second rotating frame 333 to facilitate operators to accurately determine the rotation angle of the rotation adjustment component 330.

[0045] When the above-mentioned animal detector 10 is in use, the head of the primate is first fixed by the ear bar 1122, and the ear bar 1122 can be adjusted horizontally to adapt to heads of different sizes. Then, the jaw screw 1133 is turned to move the jaw support plate 1131 up and down until it fits the lower jaw of the animal. After the head adjustment is completed, the screw and the connecting rod 137 are adjusted to move the body support plate 132 up and down until the animal's body is at a comfortable height. Finally, the clamping screw 135 is loosened, the body splint 133 is moved inward to fix the animal's body, and then the clamping screw 135 is tightened.

[0046] After the primate is fixed, the knob on the translation screw is turned to make the transducer adjustment device 300 drive the ultrasonic transducer to translate in three directions to move to the specified position of the head. In order to make the transducer perpendicular to the head surface, the worm knob 338 on the first worm 335 and the second worm 337 can be turned to adjust the angle of the transducer so that the transducer is close to the head surface and perpendicular to the head surface.
