[0049] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0050] An intracavitary probe is a probe that is introduced into the human body through a natural body orifice or a wound. After the intervening part of the intracavitary probe is introduced into the human body, it can perform ultrasonic imaging on the target part of the human body. Intracavitary probes usually include transrectal probes and transvaginal probes. Intracavitary probes are also often used in percutaneous biopsy operations. Since ultrasonic functions such as freezing and image storage in ultrasonic diagnosis are usually completed on the ultrasonic main unit, and doctors cannot operate the ultrasonic main unit during the percutaneous biopsy process, other doctors are required to operate and control the ultrasonic main unit to process the images. The intracavitary probe of the present application has control keys, and doctors can perform ultrasonic function operations by operating the control keys on the intracavitary probe. In this way, during the percutaneous biopsy operation, doctors can use the control keys to implement ultrasonic functions such as freezing and image storage.

[0051] In one embodiment, please refer to Figure 1 , the intracavitary probe includes a handle housing 1, an intervening part housing 2, a sound head (not shown in the figure), and a sound head driving mechanism (not shown in the figure). Among them, the intervening part housing 2 is used to extend into the human body through a natural body orifice or a wound. The sound head is movably installed in the intervening part housing 2, and the sound head driving mechanism is used to drive the sound head to move in the intervening part housing 2, so as to enable the sound head to scan the target position in the human body.

[0052] Please refer to Figure 1 and Figure 2 , the intervening part housing 2 is connected to the handle housing 1, and the handle housing 1 is held by the operator to operate the intracavitary probe. The handle housing 1 includes a housing 11, a first control key 12, and a second control key 13. The housing 11 includes a palm-holding part 111 for the operator's palm 3 to hold. The first control key 12 and the second control key 13 are installed on the housing 11, and the first control key 12 and the second control key 13 are arranged at intervals along the circumferential direction of the handle housing 1.

[0053] Since the handle housing 1 includes the first control key 12 and the second control key 13, when the operator holds the handle housing 1, the corresponding ultrasonic functions can be realized through the first control key 12 and the second control key 13, which is convenient for the operator to operate the intracavitary probe.

[0054] In one embodiment, please refer to Figure 1 and Figure 3 , the handle housing 1 can be held by the operator with one hand to realize one-handed operation of the intracavitary probe. In one embodiment, please refer to Figures 1 to 3, in the longitudinal direction of the handle housing 1, one end of the two ends of the handle housing 1 connected to the intervention part housing 2 is the first handle end 14, and the other end is the second handle end 15. Both the first control button 12 and the second control button 13 are close to the first handle end 14 and far from the second handle end 15. In this way, when the operator holds the handle housing 1 with one hand, the first control button 12 and the second control button 13 can be operated by swinging the thumb 4, enabling the operator to perform intracavitary probe operation with one hand and also operate the control buttons with the thumb 4 to achieve the corresponding ultrasonic functions.

[0055] In one embodiment, please refer to Figure 2 , the circumferential interval dimension a between the first control button 12 and the second control button 13 along the handle housing 1 is not greater than 40 mm, so that the thumb 4 of the single hand palm can control the first control button 12 and the second control button 13 by swinging.

[0056] In one embodiment, the first control button 12 and the second control button 13 in the present application can achieve any feasible functions, and the functions of the control buttons can be set according to the clinical scenarios, such as including functions like freeze, image storage, start, etc., so as to assist the doctor to perform single-person puncture operation. In one embodiment, the first control button 12 and the second control button 13 can either separately control the ultrasonic functions or use a variety of different interaction logics to achieve different ultrasonic functions. Of course, according to the actual usage requirements, the ultrasonic functions of the first control button 12 and the second control button 13 can also be user-defined.

[0057] In one embodiment, the intracavitary probe is a 4D probe. Of course, in some other embodiments, the intracavitary probe can also be a three-dimensional intracavitary probe or a two-dimensional intracavitary probe.

[0058] In one embodiment, please refer to Figure 3 , for the convenience of operating the first control button 12 and the second control button 13, the interval between the first control button 12 and the second control button 13 is a thumb interval 16 that can be used to place the thumb 4. In one embodiment, the dimension of the thumb interval 16 along the circumferential direction of the handle housing 1, that is, the circumferential interval dimension a between the first control button 12 and the second control button 13 along the handle housing 1, a is greater than or equal to 20 mm. When holding the handle housing 1 with one hand, the thumb 4 can be placed in the thumb interval 16. In this way, the thumb 4 can control the first control button 12 by swinging forward and control the second control button 13 by swinging backward. In addition, the thumb interval 16 formed between the first control button 12 and the second control button 13 can place the thumb 4 to prevent the thumb 4 from accidentally touching the control buttons. It should be noted that the forward and backward in the present application are only for the convenience of describing two opposite directions.

[0059] In one embodiment, please refer to Figure 5 and Figure 6, when the thumb interval 16 is greater than or equal to 20 mm, the thumb interval 16 can also be used to mount the biopsy gun 5. During percutaneous biopsy, the puncture frame 6 can be fixed on the interventional part housing 2 by clamping, and the biopsy gun 5 is mounted on the handle housing 1. A part of the biopsy gun 5 is located in the thumb interval 16, so that the biopsy gun 5 does not block the first control button 12 and the second control button 13 and does not affect the operation of the first control button 12 and the second control button 13.

[0060] Since doctors usually need to stand when using the endocavity probe for percutaneous biopsy, at this time, the doctor cannot operate the ultrasound host. Through the first control button 12 and the second control button 13 on the endocavity probe, it is convenient for the doctor performing percutaneous biopsy to control the ultrasound functions. For example, by operating the first control button 12 and the second control button 13, operations such as freezing images and storing images can be achieved. Of course, in addition to the percutaneous biopsy operation scenario, the endocavity probe of the present application can also be applied to any other feasible scenarios, such as conventional imaging examinations. The doctor can choose to operate the ultrasound host to achieve the corresponding ultrasound functions according to needs, or can also choose to achieve the corresponding ultrasound functions through the first control button 12 and the second control button 13 on the endocavity probe.

[0061] Specifically, in one embodiment, the interval dimension a between the first control button 12 and the second control button 13 along the circumferential direction of the handle housing 1 can be any value between 20 mm and 40 mm, for example, it can specifically be 20 mm, 25 mm, 30 mm, 40 mm, etc.

[0062] In some other embodiments, the dimension a between the first control button 12 and the second control button 13 along the circumferential direction of the handle housing 1 can also be less than 20 mm, for example, it can be 15 mm, 10 mm or 5 mm. Of course, when the dimension a between the first control button 12 and the second control button 13 along the circumferential direction of the handle housing 1 is 10 mm or 5 mm, usually the thumb 4 cannot be accommodated and the thumb 4 cannot be placed in. In some other embodiments, the first control button 12 and the second control button 13 are connected together and there is no interval between them.

[0063] In one embodiment, the housing 11 includes a palm-holding portion 111 for holding by a single hand palm 3. The circumferential dimension of the palm-holding portion 111, that is, the perimeter of the palm-holding portion 111, and the maximum circumferential dimension of the palm-holding portion 111 is not less than 100 mm and not greater than 120 mm. Within this dimension range, single-handed holding can generally be satisfied. The circumferential dimension of the palm-holding portion 111 is the perimeter of the palm-holding portion 111. To improve the comfort of a person holding the handle housing 1, the shape of the palm-holding portion 111 is adapted to the human palm. In the palm-holding portion 111, the perimeters at various positions in the length direction of the handle housing 1 are not required to be equal. Therefore, according to the human palm size range, the maximum circumferential dimension, that is, the perimeter, of the palm-holding portion 111 is between 100 mm and 120 mm, and specifically can be 100 mm, 110 mm, or 120 mm. Of course, in some other embodiments, for different application scenarios, the maximum circumferential dimension of the palm-holding portion 111 can be adjusted adaptively, and the maximum circumferential dimension of the palm-holding portion 111 can also be greater than 120 mm or less than 100 mm.

[0064] Regarding the types of the first control button 12 and the second control button 13, in one embodiment, please refer to Figure 2 and Figure 4 , the first control button 12 and the second control button 13 are pressing active buttons. The first control button 12 and the second control button 13 are movably mounted on the housing 11. When the first control button 12 and the second control button 13 are pressed, the first control button 12 and the second control button 13 can be activated, thereby triggering the corresponding ultrasonic function. In some other embodiments, in addition to the pressing button, the first control button 12 and the second control button 13 can also be touch buttons located on a touch screen; the first control button 12 and the second control button 13 can also be push-pull active buttons that are slidably assembled on the housing 11. In some other embodiments, the first control button 12 and the second control button 13 can be control buttons of different types. For example, the first control button 12 is a pressing active button and the second control button 13 is a touch button. Or, for another example, the first control button 12 is a touch button and the second control button 13 is a push-pull active button.

[0065] Specifically, in one embodiment, please refer to Figure 2 and Figure 4, the first control button 12 and the second control button 13 are integrally formed so that the first control button 12 and the second control button 13 can be assembled with the housing 11 as a whole. For example, the first control button 12 and the second control button 13 are made of plastic or rubber, and the first control button 12 and the second control button 13 are integrally formed by injection molding; for another example, the first control button 12 and the second control button 13 can also be made of metal materials, and the first control button 12 and the second control button 13 are integrally formed by extrusion. In some other embodiments, the first control button 12 and the second control button 13 can also be connected by means of welding, bonding or fasteners.

[0066] In some other embodiments, the first control button 12 and the second control button 13 can also be separately and independently assembled with the housing 11.

[0067] In one embodiment, please refer to Figure 2 , the housing 11 has a first keyhole 112 and a second keyhole 113. The first control button 12 is inserted into the first keyhole 112, and the second control button 13 is inserted into the second keyhole 113. In some other embodiments, the first control button 12 and the second control button 13 can also share a keyhole.

[0068] In one embodiment, please refer to Figure 2 and Figure 4 , the housing 11 further includes a control button spacing portion 114. The control button spacing portion 114 is formed between the first control button 12 and the second control button 13 in the circumferential direction of the handle housing 1. The cavity probe further includes a circuit board 7 in the housing 11. One side of the control button spacing portion 114 facing the circuit board 7 is recessed inward to form a first concave space 1143, and at least a part of the circuit board 7 protrudes toward the first concave space 1143 to form a first protrusion 76. Through the profiling design of the circuit board 7 and the control button spacing portion 114, the structural layout can be made more compact, facilitating the installation of other components.

[0069] In one embodiment, please refer to Figure 2 , a part of the first protrusion 76 protrudes into the first concave space 1143. In some other embodiments, the first protrusion 76 can also entirely protrude into the first concave space 1143. In some other embodiments, when the distance between the circuit board 7 and the control button spacing portion 114 is relatively large, the first protrusion 76 may not protrude into the first concave space 1143, and the first protrusion 76 is outside the first concave space 1143.

[0070] Specifically, in one embodiment, please refer to Figure 2, the side of the manipulation key spacing portion 114 facing the circuit board 7 is the inner side 1141, and the side of the manipulation key spacing portion 114 facing away from the circuit board 7 is the outer side 1142. The inner side 1141 is a concave surface, and the outer side 1142 is a convex surface. The circuit board 7 is bent toward the inner side 1141, that is, the whole circuit board 7 bulges in the direction of the first concave space 1143.

[0071] In one embodiment, please refer to Figure 2 and Figure 4 , the circuit board 7 includes a first electronic component 71 for operating the first manipulation key 12 and a second electronic component 72 for operating the second manipulation key 13. In one embodiment, please refer to Figure 2 and Figure 4 , the first protrusion 76 includes a first part 73, an intermediate part 74, and a second part 75. The intermediate part 74 is between the first part 73 and the second part 75, and the first part 73 and the second part 75 are symmetrically arranged. The first protrusion 76 is in an arched shape with a middle arch. The first electronic component 71 is on the first part 73, and the second electronic component 72 is on the second part 75.

[0072] In one embodiment, please refer to Figure 2 and Figure 4 , in order to improve the stability of the circuit board 7, the cavity probe further includes a support plate 8. The support plate 8 is installed in the housing 11. The support plate 8 is arranged on the side of the circuit board 7 facing away from the manipulation key spacing portion 114. The support plate 8 is used to support the circuit board 7. The side of the circuit board 7 facing the support plate 8 is recessed toward the inside of the circuit board 7 to form a second concave space 77. At least a part of the support plate 8 protrudes in the direction of the second concave space 77 to form a second protrusion 84. By supporting the circuit board 7 with the support plate 8, the strength of the circuit board 7 can be higher. The second protrusion 84 on the support plate protrudes in the direction of the second concave space 77, realizing the profiling design of the support plate 8 and the circuit board 7, which can make the structures of the two more compact and save the internal space of the handle housing.

[0073] In one embodiment, please refer to Figure 2 and Figure 4 , a part of the second protrusion 84 protrudes into the second concave space 77. In some other embodiments, the second protrusion 84 can also entirely protrude into the second concave space 77. In some other embodiments, the second protrusion 84 can also be outside the second concave space 77.

[0074] In one embodiment, please refer to Figure 2 and Figure 4 , the side of the support plate 8 facing away from the circuit board 7 is recessed toward the inside of the support plate 8, so as to create more space on the side of the support plate 8 facing away from the circuit board 7.

[0075] Specifically, in one embodiment, please refer to Figure 2 and Figure 4 , the second convex part 84 includes a first plate body 81, an intermediate plate body 82 and a second plate body 83. The first part 73 is mounted on the first plate body 81, and the second part 75 is mounted on the second plate body 83. The first plate body 81 and the second plate body 83 are symmetrically arranged. The second convex part 84 is in an arched shape with a middle arch.

[0076] In some other embodiments, in addition to the arched shape, the circuit board 7 and the support plate 8 can also be in other shapes. For example, the first part and the second part of the support plate are coplanar, the side of the third part facing away from the circuit board is recessed towards the inside of the third part, and the side facing the circuit board protrudes to form a convexity; for another example, the first part and the second part of the support plate are directly connected together to form an inverted V shape; for another example, the support plate can also be an arc-shaped plate; similarly, the circuit board can also adopt a shape similar to any one of the above support plates.

[0077] In one embodiment, please refer to Figure 2 and Figure 4 , the circuit board 7 is a flexible circuit board, and the flexible circuit board can be deformed, which is more conducive to being installed on the irregular support plate 8.

[0078] In some other embodiments, when the space in the handle housing 1 meets the requirements, both the circuit board 7 and the support plate 8 can be flat plates. The manipulation key interval part 114 can also be a flat plate structure.

[0079] In one embodiment, please refer to Figure 6 , the handle housing 1 has a symmetric plane extending along the length direction of the handle housing 1. The outer surface of the housing 11 is symmetric about the symmetric plane, and the first manipulation key 12 and the second manipulation key 13 are symmetrically arranged about the symmetric plane. In this way, the first manipulation key 12 and the second manipulation key 13 can be suitable for operators who are left-handed and also for operators who are right-handed. In some other embodiments, the handle housing 1 may not have a symmetric plane. In some other embodiments, the first manipulation key 12 and the second manipulation key 13 may also be asymmetric about the symmetric plane.

[0080] In order to be suitable for thumbs 4 of different lengths, in one embodiment, please refer to Figure 6 , the first manipulation key 12 and the second manipulation key 13 are long strip-shaped keys extending along the length direction of the handle housing 1. In some other embodiments, only one of the first manipulation key 12 and the second manipulation key 13 is in a long strip shape. In some other embodiments, at least one of the first manipulation key 12 and the second manipulation key 13 can also be a circular key or an irregularly shaped key.
