Description

Lifting balance control device and breast ultrasound imaging system

Technical field

The present application relates to the technical field of medical equipment, and in particular to a lifting balance control device and a breast ultrasound imaging system.

Background technique

The breast ultrasound imaging system has detection equipment. The detection equipment includes a probe box and a cantilever structure. The detection equipment is about 30kg. During use, the probe box in the detection equipment needs to be able to be flexibly raised and lowered to the required height and locked in this position.

The conventional solution is to directly drive the detection equipment to move up and down by a motor. The motor needs to overcome a weight of about 30 kg. The motor requires a large amount of power, which is disadvantageous to the size, space, cost, heat dissipation, and noise of the motor. At the same time, it is difficult for the motor's own holding torque to completely and reliably lock the detection equipment at the designated position, and an additional locking mechanism is required; once the locking mechanism fails, the detection equipment will fall sharply, which poses a great safety risk.

In addition, the operator needs to manually adjust the height of the detection equipment (the motor is not working at this time), and needs to overcome the weight of about 30kg, which will be very laborious and even impossible to operate.

Summary of the Invention

An embodiment provides a lifting balance control device, including:

At least two runners;

The lifting belt is installed on the runner. The lifting belt has two lifting sections with opposite lifting directions, and one lifting section of the transmission belt is connected to the detection equipment of the breast ultrasound imaging system;

Counterweight, the counterweight is installed on another lifting section of the lifting belt;

The driving part is connected with at least one rotating wheel, and is used for driving the rotating wheel to drive the lifting belt to move up and down.

An embodiment provides a breast ultrasound imaging system, including a detection device, the detection device includes a cantilever and a probe box, and further includes the lifting balance control device described above.

According to the lifting balance control device and the breast ultrasound imaging system of the above embodiments, since the weight blocks and detection equipment are installed on both sides of the timing belt, on the basis of the weight balance, the motor only needs to output a small amount of power. It can drive the stable lifting of the detection equipment, so that a motor with a smaller power can be selected, which reduces the size, occupied space, cost, heat dissipation and noise of the motor. The setting of the weight block also makes manual adjustment of the detection equipment to greatly lift and save more effort. In addition, the small output power of the motor can lock the detection equipment at a height position, without the need for additional locking devices, simplifying the structure, reducing costs, and avoiding the safety risk of the detection equipment falling sharply.

detailed description

In the embodiment of the present invention, a lifting balance control device is provided. The detection device of the breast ultrasound imaging system is balanced by a weight block, so that the driving device can drive the detection device of the breast ultrasound imaging system by providing only a small driving force. Lifting, moving and locking in one position, and can avoid the safety risk of the sudden fall of the detection equipment of the breast ultrasound imaging system, and ensure the safe detection of the detection equipment of the breast ultrasound imaging system.

As shown in FIG. 1, in one embodiment, a lifting balance control device is provided. The lifting balance control device mainly includes a runner 101, a lifting belt 102, a weight 103, and a driving member 104.

In this embodiment, the runner 101 is a synchronous pulley. There are two synchronous pulleys, and the two runners 101 are spaced up and down and installed in a vertical plane. The lifting belt 102 is a timing belt which is closed end to end. The timing belt is installed on a timing belt wheel. The timing belt wheel can drive the timing belt to move up and down.

There are two upgrade sections on opposite sides of the lifting belt 102. As shown in FIG. 1, the lifting section on the right side is connected to the detection device 210 of the breast ultrasound imaging system. The detection device 210 mainly includes a cantilever and a probe. Box, the weight block 103 is installed on the lifting section of the lifting belt 102 on the left side. The weight of the weight block 103 is about 30 kg, which is basically equal to the weight of the detection device 210. The weight block 103 serves as the balance detection device 210 effect.

In other embodiments, there are four runners 101, the array is installed in a vertical plane, the lifting belt 102 is mounted on the four runners 101, and the four runners 101 are installed, which can The lifting section is spaced to avoid the weight 103 and the detection device 210 to prevent the two from colliding.

In other embodiments, the runner 101 can also be a sprocket, and the corresponding lifting belt 102 is a chain belt. The sprocket can also drive the chain belt to drive the detection device 210 to move up and down, but the movement accuracy is slightly lower than that of the synchronous belt and synchronous gear. combination.

In this embodiment, the driving member 104 is a motor. The motor has one. The output shaft of the motor is connected to the rotating wheel 101 located below. The motor is used to drive the positive and negative rotation of the rotating wheel 101. The rotating wheel 101 drives the lifting belt 102 to drive. The detection device 210 moves up and down.

In other embodiments, two motors can also be provided, and each motor is connected to a rotating wheel 101, which can further reduce the output power of the motor. The upper and lower two rotating wheels 101 are simultaneously active wheels, and the lifting movement of the detection device 210 More stable.

Since the lifting balance control device provided in this embodiment has equal weight weights 103 and detection equipment 210 installed on both sides of the timing belt, the motor only needs to output less power on the basis of the balance weight 103 The detection device 210 can be driven to rise and fall steadily, so that a motor with a smaller power can be selected, which reduces the size, occupied space, cost, heat dissipation, and noise of the motor. The setting of the weight block also makes manual adjustment of the detection device 210 significantly easier to lift and lower, and the smaller output power of the motor can also lock the detection device 210 at a height position without the need for additional locking devices, simplifying the structure It also reduces the cost and also avoids the safety risk of a sudden drop of the detection device 210.

As shown in FIG. 2, in one embodiment, another lifting balance control device is provided, and the clutch 105 is mainly added on the basis of the above embodiment.

As shown in FIG. 3, the clutch 105 of this embodiment is an electromagnetic clutch. The clutch 105 is installed between the output shaft of the driving member 104 (motor) and the runner 101. The clutch 105 mainly includes a driving member 105a and a driven member 105b. A driving shaft 105c is mounted on the driving member 105a, and a driven member 105b is mounted on the driving member 105a. In the driven shaft 105d, the output shaft of the motor is connected to the driving shaft 105a on the clutch 105 through the coupling 106, and the runner 101 is connected to the driven shaft 105b on the clutch 105. The driving member 105a and the follower 105b can be in a state of being coupled to each other or a state of being separated from each other, and can be switched between a state of being coupled and a state of being separated from each other. When the driving part 105a and the driven part 105b in the clutch 105 are combined (that is, in a mutually coupled state), the clutch 105 transmits the torque output from the driving part 104 to the runner 101 to achieve driving lift; when the driving part in the clutch 105 is driven When 105a and the follower 105b are separated (that is, in a separated state from each other), the driving member 104 is disconnected from the runner 101 to form overload protection.

During the lifting process of the detection device 210, when the detection device 210 is pressed to the human body to reach a certain pressure, the electromagnetic clutch will activate the overload protection function, that is, when the torque output by the motor is greater than the rated torque of the clutch 105, the motor continues to rotate, and the clutch will slip and slip. (I.e., the driving member 105a and the driven member 105b of the clutch are changed from a coupled state to a separated state), the transmission of the motor torque is interrupted, and the suspension detection device 210 is continued to move up and down to play a role of safety protection. However, the conventional safety protection function requires a pressure sensor to be installed on the detection device 210, which is costly and difficult to design in terms of structure. Moreover, since the sound window in the detection device 210 is a disposable consumable, there is no good feasibility.

Installing a clutch 105 between the motor and the runner 101 also avoids passive rotation of the motor output shaft, and avoids situations like "charging".

As shown in FIG. 4, in one embodiment, a breast ultrasound imaging system is provided. The breast ultrasound imaging system in this embodiment mainly includes a detection device 210 and a main body 220. The detection device 210 includes a cantilever 211 and a probe box 212. The cantilever 211 is mounted on the main body 220, and the probe box 212 is mounted on the cantilever 211.

As shown in FIG. 1 or FIG. 2, the detection device 210 of the breast ultrasound imaging system may be installed on the lifting belt 102 of the lifting balance control device described in the foregoing embodiment.

The lifting balance control device is provided with a weight block 103 to balance with the detection equipment 210, which improves the stability of the detection equipment 210 during lifting. The lifting balance control device is also provided with a clutch 105, which can provide safety protection, prevent human body from being damaged by overpressure, and prevent the motor from passively rotating.

The breast ultrasound imaging system provided in this embodiment has high stability, simple structure, and only requires a smaller power motor to drive the smooth lifting and locking of the detection device 210.

The above uses specific examples to illustrate the present invention, but is only used to help understand the present invention, and is not intended to limit the present invention. For those of ordinary skill in the art, according to the idea of the present invention, changes can be made to the above specific implementations.
