Technical Field
[0001] This utility model relates to the field of ultrasound detection, and in particular to a breast ultrasound examination device. Background Technology
[0002] The incidence of breast diseases has increased significantly in recent years, which has had a considerable impact on the world's population and economy. Therefore, early screening is particularly crucial. Breast ultrasound examination devices are important tools for the screening and diagnosis of breast diseases. They use an ultrasound probe composed of piezoelectric crystals, which generates high-frequency vibrations when energized. These vibrations emit extremely high-frequency sound waves. After the sound waves penetrate the skin and enter the body, they are reflected back into the ultrasound probe by different tissues, generating electrical signals that form an image. Finally, the image is displayed to complete the screening and diagnosis of diseases.
[0003] During breast ultrasound examinations, to prevent clothing or other coverings from obstructing sound waves and hindering the accuracy of the examination, the patient usually needs to keep the area being examined and the surrounding breast exposed. A gel is applied to the area to reduce air gaps between the ultrasound probe and the skin. However, the gel is cold, and the area where the ultrasound probe contacts the skin is also cold, which undoubtedly causes significant discomfort for the patient in cold weather. Utility Model Content
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a breast ultrasound examination device to solve the problem that the coldness of the gel and ultrasound probe can easily cause discomfort.
[0005] To solve the above-mentioned technical problems, the present invention provides a breast ultrasound examination device including a control imaging unit, a robotic arm disposed on the control imaging unit, and an ultrasound scanning head connected to the end of the robotic arm away from the control imaging unit. The ultrasound scanning head has a contact surface for contacting the skin, and a heating part for dispensing and heating a gel is provided inside the ultrasound scanning head. The heating part has a pushing structure that can deliver the heated gel to the contact surface.
[0006] Furthermore, the heating unit includes a device bottle connected to the ultrasonic scanning head and having a device cavity for assembling the gel, and a heating structure formed on the device bottle for heating the gel within the device cavity, the device cavity communicating with a contact surface, and the pushing structure connected to the device bottle and having a push plug that can extend and seal into the device cavity.
[0007] Furthermore, the device bottle is connected inside the ultrasonic scanning head and has a connection port extending out of the ultrasonic scanning head. The pushing structure includes a connecting sleeve detachably connected to the connection port and a driving member fixedly connected to one side of the connecting sleeve. The driving member has a telescopic output shaft coaxial with the connecting sleeve and located inside it. The pushing plug is coaxially connected to the output shaft.
[0008] Furthermore, the shape and size of the connection port and the device cavity are consistent; the push plug includes a rod portion connected to the output shaft and a plug portion coaxially connected to the end of the rod portion away from the output shaft, the shape and size of the plug portion are consistent with the device cavity and it is located inside the connecting sleeve when the output shaft is in the retracted state.
[0009] Furthermore, the heating structure is arranged around the inner wall of the device cavity, and heat-conducting sheets that fit the heating structure and are flush with the inner wall of the device cavity are laid on the cavity wall where the heating structure is located. The heat-conducting sheets shield the heating structure relative to the device cavity.
[0010] Furthermore, the heating unit also includes an output tube connected at one end to the side of the device cavity away from the pushing structure and a temperature sensor disposed inside the output tube.
[0011] Furthermore, the ultrasonic scanning head includes a housing connected to a robotic arm and having an open cavity inside, a transducer disposed within the cavity, and an acoustic lens disposed on the opening side of the cavity. The contact surface is formed on the side of the acoustic lens facing away from the cavity, and the heating part is connected to the housing.
[0012] Furthermore, a receiving cavity connected to the output tube is formed on the acoustic lens, and the receiving cavity is connected to the contact surface.
[0013] Furthermore, the acoustic lens includes a first lens disposed on the opening side of the cavity and a second lens connected to the cavity and close to the opening side by a connecting block. The first lens, the connecting block and the second lens form the receiving cavity, and the first lens has an adhesive outlet hole communicating with the receiving cavity.
[0014] Furthermore, the output tubes and transducers are spaced apart.
[0015] The breast ultrasound examination device of this invention has at least the following beneficial effects: by adding a heating part, the gel can be stored and heated. When the breast needs to be examined, the heated gel is delivered to the contact surface by a pushing structure. The warm gel will not cause discomfort to the examinee when it comes into contact with the skin. At the same time, it can reduce the coldness of the contact surface to a certain extent by transferring heat to the contact surface, so that the ultrasound scanning head will no longer irritate the examinee's skin when used, thus increasing comfort.

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] For reference Figures 1 to 3 The breast ultrasound examination device of this utility model includes a control imaging unit 1, a robotic arm 2 mounted on the control imaging unit 1, an ultrasound scanning head 3 connected to the end of the robotic arm 2 away from the control imaging unit 1, and a heating part 4 mounted on the ultrasound scanning head 3. The control imaging unit 1 is used to operate and control the opening and closing of the ultrasound scanning head 3. The robotic arm 2 facilitates the movement of the ultrasound scanning head 3 to the examination site of the patient. The ultrasound scanning head 3 images the tissue structure of the examination site by contacting it and the image is transmitted to the control imaging unit 1 for display. The heating part 4 operates a heating gel when the ultrasound scanning head 3 is started and outputs warm gel during the examination to reduce the discomfort caused by the ultrasound scanning head 3. The gel is used to eliminate air during the examination and reduce energy loss.
[0024] In this embodiment, the control imaging unit 1 includes a base 11, a control console 12 mounted on the base 11, and a display screen 13 mounted on the base 11. The control console 12 includes a housing, internal circuitry and a controller disposed within the housing. The display screen 13, the ultrasonic scanning head 3, and the controller are all connected to the internal circuitry, and the controller is electrically connected to the display screen 13 and the ultrasonic scanning head 3. The control console 12 can be used to turn the display screen 13, the ultrasonic scanning head 3, and the heating unit 4 on and off. A button electrically connected to the controller is connected to the housing of the control console 12, and pressing the button controls the opening and closing of each part. A power supply electrically connected to each part is also provided inside the housing. When the control imaging unit 1 is in use, the device is turned on by pressing the button, which lights up the display screen 13. The ultrasonic scanning head 3 is activated, and the heating unit 4 is activated to preheat the gel. After the gel is preheated, the heating unit 4 sends a signal to the controller, and the display screen 13 indicates that an ultrasonic examination can be performed. Then, by pushing the ultrasonic scanning head 3, the robotic arm 2 supports its movement. The controller processes the electrical signals emitted by the ultrasonic scanning head 3 and then displays them on the display screen 13. Four omnidirectional wheels 14 can be installed at the bottom of the base 11 to facilitate the movement of the device.
[0025] In this embodiment, the robotic arm 2 includes multiple connecting rods 21 connected end to end. One end of the connecting rod 21 at the far end is fixedly connected to the base 11. The ends of any two adjacent connecting rods 21 are connected by a rotary joint 22 so that they can rotate. The other end of the connecting rod 21 at the far end is connected to the ultrasonic scanning head 3 so that it can move when the ultrasonic scanning head 3 is pushed, thereby providing support for the ultrasonic scanning head 3 during the examination and allowing it to be moved.
[0026] In this embodiment, the ultrasonic scanning head 3 includes a housing 31 connected to the robotic arm 2 and having an open cavity 311 inside, a transducer 32 disposed in the cavity 311, and an acoustic lens 33 disposed on the opening side 312 of the cavity 311. The cavity 311 is open on the downward side, which is its opening side 312, and the acoustic lens 33 is located here so that the acoustic lens 33 can face downward and contact the examination site of the examinee in a supine position.
[0027] In this embodiment, the housing 31 can be a metal housing or a rigid housing such as plastic, and it is hollow inside. The top of the housing 31 is fixedly connected to the robotic arm 2. The transducer 32 is fixedly connected inside the cavity 311 and located in the middle of the housing 31. The transducer 32 consists of several piezoelectric crystal arrays, and the piezoelectric crystal is the core component for generating, emitting, and receiving ultrasonic waves. Inside the piezoelectric crystal is lead zirconium titanate, which has excellent piezoelectric properties. When energized, its internal lattice deforms rapidly, generating high-frequency vibrations. Accompanying the vibrations are high-frequency sound waves. After receiving ultrasonic waves, the lead zirconium titanate can convert mechanical vibrations into electric charges, forming a piezoelectric effect. Copper wires for generating and receiving electrical signals are provided on the lead zirconium titanate. During detection, the ultrasonic camera captures various tissues inside the human body. When it encounters different tissues, echoes are generated and vibrations occur, causing the lead zirconium titanate to generate electrical signals. These electrical signals are then sent to the controller, which records them to form an image, completing the ultrasonic inspection. In this embodiment, the acoustic lens 33 is mounted flush with or protrudes from the bottom of the housing 31 after being installed on the opening side 312. The side of the acoustic lens 33 facing away from the cavity 311 is defined as a contact surface. This contact surface is used to contact the skin of the examined area during the examination to help the transducer 32 focus the ultrasound waves, while simultaneously isolating the gel to prevent it from contacting the transducer 32. It should be noted that two handles 314 are provided on the top surface of the outer side of the housing 31, so that medical personnel can easily adjust the position of the ultrasound scanning head 3 by holding the handles 314 during the examination.
[0028] In this embodiment, the heating unit 4 includes a device bottle 41 connected to the ultrasonic scanning head 3, a heating structure 42 formed on the device bottle 41 for heating the gel in the device cavity 411, a pushing structure 43 connected to the device bottle 41, an output tube 44 with one end connected to the side of the device cavity 411 away from the pushing structure 43, and a temperature sensor 45 disposed in the output tube 44. The device bottle 41 has a device cavity 411 for storing gel before examination. The heating structure 42 is used to heat the gel in the device cavity 411 at a constant temperature. The device cavity 411 is connected to the contact surface. The pushing structure 43 pushes the warm gel during the ultrasonic examination. The output tube 44 allows the gel to be pushed to the contact surface. The temperature sensor 45 is electrically connected to the controller to detect the temperature of the gel in the output tube 44 in real time to avoid the temperature being too high or too low, thereby improving comfort.
[0029] In this embodiment, the device bottle 41 is connected within the cavity 311 of the ultrasonic scanning head 3 and has a connection port 412 extending out of the ultrasonic scanning head 3, which communicates with the device cavity 411. The device bottle 41 is made of a sturdy and durable material such as metal to ensure its durability.
[0030] In this device, the heating structure 42 includes an electric heating element embedded within the device bottle 41 and arranged around the inner wall of the device cavity 411. The electric heating element is electrically connected to the controller and the power supply, and surrounds the side and bottom walls of the device cavity 411 to heat the gel. Since the gel is a highly thermally conductive material, the heating element provides sufficient heat to raise the temperature. During the process of the pushing structure 43 pushing the gel, the gel at the center mixes with the gel at the edges as it is squeezed towards the output tube 44, further mixing the gel and making the temperature more uniform. To improve the service life of the electric heating element, heat-conducting sheets 46 are laid on the bottom and side walls of the device cavity 411 where the heating structure 42 is located. These sheets adhere to the heating structure 42 and are flush with the inner wall of the device cavity 411. The heat-conducting sheets 46 shield the electric heating element of the heating structure 42 relative to the device cavity 411, protecting the electric heating element while ensuring heat conduction. The heat-conducting sheet 46 is made of a high thermal conductivity material such as copper. The thickness of the heat-conducting sheet 46 should be kept to a minimum of about 1 mm to minimize the heating effect on the gel.
[0031] As defined in this device, the pushing structure 43 includes a connecting sleeve 431 detachably connected to the connecting port 412, a driving member 432 fixedly connected to the connecting sleeve 431 on the side away from the device bottle 41, and a pushing plug 433 coaxially connected to the driving member 432 on the side facing the device bottle 41. The connecting sleeve 431 allows the driving member 432 to be installed or removed from the connecting port 412 of the device bottle 41. The driving member 432 drives the pushing plug 433 to move back and forth within the device cavity 411, thereby pushing the gel to be delivered to the contact surface. An inner cavity opening towards the device bottle 41 is formed between the driving member 432 and the connecting sleeve 431. An internal thread can be provided on the inner wall of the connecting sleeve 431, and an external thread can be provided on the outer wall of the connecting port 412 to mate with it. This allows the driving component 432 to be screwed onto the connecting port 412 via the connecting sleeve 431. Before adding gel, the driving component 432 can be removed to insert gel into the device cavity 411. After gel replenishment, the connecting sleeve 431 can be screwed back onto the connecting port 412 to seal the gel. The driving component 432 can be a telescopic cylinder electrically connected to the controller, or it can be a manual push plate. When the driving component 432 is a manual push plate, it is fixedly connected to the end of the push plug 433 away from the device cavity 411 and its size is larger than the size of the connecting port 412. In this embodiment, the driving component 432 is a telescopic cylinder with a telescopic output shaft coaxial with the connecting sleeve 431 and located inside the connecting sleeve 431. The push plug 433 is coaxially connected to the output shaft so that the driving component 432 can move the push plug 433 when it is running. The push plug 433 includes a rod connected to the output shaft and a plug coaxially connected to the end of the rod away from the output shaft. The rod facilitates the connection between the plug and the output shaft of the drive unit 432. The plug includes an inner layer made of rigid material and fixedly connected to the rod, and a rubber or silicone layer surrounding the inner layer. When the push plug 433 passes through the connection port 412 and extends into the device cavity 411, the rubber layer adheres to the inner wall of the device cavity 411 to achieve a seal. The connection port 412 and the device cavity 411 have the same shape and size, and the plug has the same shape and size as the device cavity 411, both of which can be cylindrical structures. To facilitate the disassembly of the drive unit 432, when the output shaft is in the retracted state, the entire plug is located inside the connecting sleeve 431, preventing the push plug 433 extending outside the connecting sleeve 431 from affecting the disassembly of the drive unit 432.
[0032] In this embodiment, one end of the output tube 44 is fixedly connected to the bottom of the housing 31 at the device bottle 41, and its diameter is smaller than the diameter of the device cavity 411. This allows the gel to mix better and neutralize the temperature when pushed into the output tube 44 by the pusher plug 433. The other end of the output tube 44 extends to the acoustic lens. The temperature sensor 45 is fixedly installed at the bottom of the device bottle 41 and inserted into the output tube 44 in a sealed state. It should be noted that the output tube 44 should be as short as possible to reduce heat loss. The temperature sensor 45 is electrically connected to the controller and the power supply, and its temperature range is set to 40-50°C. This ensures that when the gel exceeds the set temperature of 50°C, the heating structure 42 stops heating, and when the temperature drops below 40°C, the heating structure 42 starts heating the gel. In this way, even if the temperature drops to a certain extent due to contact between materials during gel delivery, it can ensure that the skin is not irritated, thus keeping it at a consistently comfortable temperature.
[0033] In this embodiment, a receiving cavity 331 communicating with an output tube 44 is formed on the acoustic lens 33. The receiving cavity 331 communicates with the contact surface so that the heated gel is transported to the receiving cavity 331 and then conveyed to the contact surface under the pressure of the pusher plug 433. In the scope defined in this embodiment, the acoustic lens 33 includes a first lens 332 disposed on the opening side 312 of the cavity 311 and a second lens 333 connected to the cavity 311 and close to the opening side 312 by a connecting block 313. The receiving cavity 331 is formed between the first lens 332, the connecting block 313 and the second lens 333. A gel outlet hole 334 communicating with the receiving cavity 331 is opened on the first lens 332. The heated gel is pushed into the receiving cavity 331. Part of the heat of the gel is absorbed by the first lens 332 and the second lens 333, so that the contact surface is no longer cold. The temperature of the gel, which is close to 50°C, can be maintained at a temperature higher than the human body temperature after being absorbed by the acoustic lens 33, thus ensuring comfort. To prevent the gel temperature from being excessively lowered, the transducer 32 and the second lens 333 are spaced apart, but the gap must be kept within 1 cm to minimize the impact of the spaced transducer 32 and the second lens 333 on the sound waves. Furthermore, the transducer 32 and the output tube 44 are spaced apart without interfering with each other. The volume of the receiving cavity 331 should not be too large; therefore, its thickness should be kept within 5 mm to prevent increased gel accumulation. The first lens 332 should be removable for easy removal and cleaning after inspection.
