Description

FIELD OF THE INVENTION [0001] The present invention relates to a fluid supply device for an ultrasonic medical device, a treatment head, and an ultrasonic medical device including the fluid supply device,

One embodiment of the present invention relates to a fluid supply device for an ultrasonic medical device and an ultrasonic medical device including the same. The present invention relates to a fluid supply device for use in an ultrasonic medical instrument for treating non-invasive lesions such as cancer cells of a patient by irradiating high intensity intensive ultrasonic waves, and an ultrasonic medical instrument including the same.

The contents described in this section merely provide background information on the embodiment of the present invention and do not constitute the prior art.

The HIFU (High Intensity Focused Ultrasound) device is a device that treats patients by burning tissues using high heat generated from the focus when collecting high intensity ultrasound energy in one place.

If you focus an ultrasound about 100,000 times stronger than the intensity of the ultrasonic waves used in diagnosis, heat is generated at the focus region. This is similar to the case where the sunlight is collected by the convex lens and heat is generated at the focus region. The ultrasound itself is harmless to the human body and generates heat only at the focal point where the ultrasound is concentrated. Therefore, it is possible to treat the lesion in the body without using a knife or a needle and without general anesthesia.

The structure of the HIFU device can be roughly divided into a base, a treatment head, and a supporting structure which is installed on the base and supports the treatment head.

Among them, the treatment head includes transducers and containers that convert electrical energy into ultrasonic energy. The container is a flexible membrane that is attached to the treatment head while wrapping the transducer, and serves to hold the fluid that cools the high heat generated when ultrasonic waves are irradiated from the transducer.

Conventional techniques have manually provided fluid to the container manually to allow the fluid to be contained in the container. However, this is inconvenient to the user and takes a long time to prepare for treatment.

Further, the high temperature generated when the ultrasonic wave is irradiated from the transducer may damage the container, and if the treatment head touches the skin of the patient directly, the transducer may be burned due to the high temperature.

In particular, when the treatment head is small, the position of the head is easy to move, which is advantageous in use. However, since the volume of the container is small, the medium can not be loaded in a large quantity.

There is a need for a fluid supply device having a new method or structure capable of automatically supplying and draining a medium to a treatment head to solve the above-described problems, and an ultrasonic medical instrument including the same.

In addition, there is a demand for a treatment head including a cooling device of a new structure that suppresses a temperature spike of a medium contained in a container of a treatment head, and an ultrasonic medical device including the same. This problem is particularly problematic when the treatment head is small.

One embodiment according to the present invention is a treatment head comprising a fluid space for containing a first fluid; A circulation path including the fluid space on the treatment head, through which the first fluid flows; A sensor installed on the circulation path for measuring a pressure of the first fluid flowing through the circulation path; A pump installed on the circulation path for pumping the first fluid; And a control unit for receiving the signal output from the sensor and controlling the pump.

Yet another embodiment according to the present invention is a treatment head having a fluid space for containing a first fluid and having a second inlet and a second outlet; A second fluid pipe disposed on the fluid space, the second fluid pipe having one end connected to the second inlet and the other end connected to the second outlet; A circulation path including the second fluid pipe and through which a second fluid for heat exchange with the first fluid circulates; And a pump installed on the circulation path for pumping the first fluid.

An embodiment according to the present invention comprises: circulating a first fluid on a circulation path provided with a treatment head by operating a pump; Closing an outlet of the first fluid installed in the treatment head; Sensing a pressure value of the first fluid and transmitting the sensed pressure value to the controller; And stopping the operation of the pump when the pressure of the first fluid reaches a predetermined value by analyzing the sensed information.

One embodiment according to the present invention is a dispenser comprising: a body having a container at one end and having a second inlet and a second outlet for a second fluid; A transducer installed inside the body and irradiating ultrasound; And a second fluid pipe disposed on a fluid space between the container and the transducer, one end connected to the second inlet and the other end connected to the second outlet.

One embodiment according to the present invention provides a medical device comprising the fluid supply device or the treatment head described above.

The present invention provides a fluid supply device and a treatment head having a novel structure capable of automatically supplying and draining a medium to a treatment head to solve the above-described problems.

In addition, the present invention provides a cooling device inside the treatment head so that the temperature of the medium can be prevented from suddenly rising by continuously circulating the cooling water even during the treatment, and the treatment time can also be increased.

In addition, the effects of the present invention have various effects such as excellent durability according to the embodiments, and such effects can be clearly confirmed in the description of the embodiments described later.

Fig. 4 is a side view of the first embodiment of Fig. 5 is a flowchart showing a fluid supply method according to an embodiment of the present invention.

First, a fluid supply device 10 according to an embodiment of the present invention includes a treatment head 20, a circulation path 30, a sensor, a pump, and a control unit 50. [

The treatment head 20 includes a body 24 and a transducer 23 installed inside the body 24 for transmitting and receiving ultrasonic waves and a container 24 surrounding the transducer 23 and attached to one side of the body 24 (22).

Here, the transducer 23 may include a piezoelectric element, and is a device capable of converting electric energy into vibrational energy through the operation of the piezoelectric element. One embodiment of the transducer 23 may be manufactured by attaching an acoustic matching layer to the front portion of the piezoelectric element and attaching a sound-absorbing layer to the rear portion. A lens may be formed on the front portion of the acoustic matching layer. The ultrasonic waves are generated by the piezoelectric elements, and the ultrasonic waves generated from the piezoelectric elements can be irradiated through the lenses.

The treatment head (20) includes a fluid space (29) capable of containing a first fluid (35). The fluid space (29) is surrounded by the body (24) and the container (22).

The first fluid 35 serves as a medium of ultrasonic waves. That is, the ultrasonic waves irradiated from the transducer 23 can be smoothly transmitted to the object to be treated through the first fluid 35. The first fluid 35 serves as cooling water for suppressing temperature rise due to heat generated when the transducer 23 irradiates the ultrasonic waves.

The first fluid 35 may be water depending on the embodiment.

The circulation path 30 includes a fluid space 29 on the treatment head 20 and is connected to the first inlet 25 and the first outlet 27 of the treatment head 20 respectively. The treatment head 20 may have a first inlet 25 and a first outlet 27 formed in the body 24, depending on the embodiment.

The first fluid 35 flows through the circulation path 30 and flows into the fluid space 29 through the first inlet port 25 and out of the fluid space 29 through the first outlet port 27.

The sensor measures the pressure of the first fluid 35 flowing through the circulation path 30 and transmits a signal having pressure information to the control unit 50. The control unit 50 may be electrically connected to the sensor or the pump, depending on the embodiment. The controller 50 receives a signal related to the pressure of the first fluid 35 from the sensor to operate the pump or stop the operation.

When the pressure of the fluid space 29 reaches a predetermined value while the first fluid 35 is supplied to the fluid space 29, the sensor operates to interrupt the operation of the pump to stop the supply of the first fluid 35 .

When the pressure of the fluid space 29 reaches a predetermined value while the first fluid 35 is drained in the fluid space 29, the sensor operates to shut off the operation of the pump, thereby draining the first fluid 35 .

The pump may include a first pump 43 and a second pump 44, depending on the embodiment. The first pump 43 serves to introduce the first fluid 35 into the treatment and the second pump 44 functions to drain the first fluid 35 from the treatment.

The sensor does not necessarily need to be installed in the fluid space 29 but may be installed at a position at which the pressure of the fluid space 29 on the circulation path 30 can be known.

The sensor may comprise a first sensor 41 and a second sensor 42, depending on the embodiment. The first sensor 41 may be disposed on the circulation path 30 between the first inlet 25 and the first pump 43 and the second sensor 42 may be disposed between the first outlet 27 and the second pump 43. [ (44).

The control unit 50 may receive the signal output from the first or second sensor 42 to control the first or second pump 44. [

The control unit 50 may control the flow rate of the fluid to be supplied to the treatment head 20 when the first fluid 35 is supplied with a signal indicating a pressure value higher than a predetermined value from the first sensor 41, So that the operation of the first pump 43 can be stopped.

The control unit 50 may also provide a signal indicating a pressure value lower than a predetermined value from the second sensor 42 when the first fluid 35 flows out from the treatment head 20 And to stop the operation of the second pump 44 when the input is received.

The first pump 43 and the second pump 44 do not necessarily have to be operated simultaneously, and can operate independently of each other as required.

One of the features of the fluid supply device 10 according to the embodiment of the present invention is that the first fluid 35 is automatically supplied and drained to the treatment head 20. [ That is, since the supply and drainage are automatically performed by the sensor and the control unit 50, the user of the ultrasonic treatment apparatus does not need to supply the first fluid 35 manually. The point at which the first fluid 35 is automatically supplied and drained has the advantage of being able to quickly fill an appropriate amount of the first fluid 35 with the treatment head 20, And has the advantage of shortening the time it takes to prepare for treatment.

The fluid supply method according to the embodiment of the present invention may include a step S100 of circulating the first fluid 35 on the circulation path 30 in which the treatment head 20 is installed by operating the pump. And closing the outlet of the first fluid 35 provided in the treatment head 20 (S200). The method may further include sensing a pressure value of the first fluid 35 and transmitting the sensing value to the controller 50 (S300). Finally, the control unit 50 may analyze the sensed information and stop the operation of the pump when the pressure of the first fluid 35 reaches a predetermined value (S400).

The fluid supply method according to the embodiment of the present invention will be described more specifically. First, the control unit 50 opens both the first inlet 25 and the first outlet 27 to circulate the first fluid 35 on the circulation path 30 (S100). This is because if only the first inlet 25 is opened and the first fluid 35 is introduced into the treatment head 20 while the first outlet 27 is blocked, This is because the pressure of the first fluid 35 rises before the treatment head 20 is filled with an appropriate amount of the first fluid 35, so that the sensor can stop the operation of the first pump 43.

Next, the control unit 50 closes the first outlet 27 to fill the fluid space 29 with the first fluid 35 (S200). The first sensor 41 senses the first fluid 35 and transmits the sensed first fluid 35 to the control unit 50 in step S300 and the control unit 50 controls the first sensor 41 It is possible to stop the operation of the first pump 43 and block the inflow of the first fluid 35 in step S400.

If the pressure in the fluid space 29 is higher than the predetermined pressure, the second sensor 42 and the control unit 50 can operate the second pump 44 to drain water. In addition, if the pressure in the fluid space 29 is lower than the predetermined pressure, the control unit 50 can stop the operation of the second pump 44. [

The method by which the control unit 50 controls the first or second pump 44 by the signal received from the first or second sensor 42 is not limited to the above-described embodiment, and various other configurations are possible.

One of the features of the present invention is that the treatment head 20 is provided with a separate cooling device for the first fluid 35. In addition, another feature of the present invention is that the cooling device operates in conjunction with the fluid supply device 10.

In the fluid supply device 10 according to another embodiment of the present invention, the treatment head 20 may be formed with the second inlet 26 and the second outlet 28, and the second fluid pipe 21). The pipe 21 for the second fluid may be provided in the fluid space 29. One end of the second fluid pipe 21 may be connected to the second inlet 26 and the other end may be connected to the second outlet 28. The second fluid pipe 21 is preferably installed between the transducer 23 and the container 22 provided inside the treatment head 20. Since the transducer 23 mainly generates heat at the portion irradiated with the ultrasonic waves, the temperature at the front of the surface irradiated with the ultrasonic waves is the highest. Therefore, it is preferable to provide the second fluid pipe 21, which is the cooling device, in front of the rear side or the side surface of the transducer 23 where the temperature of the first fluid 35 is the highest, in terms of efficiency of cooling operation . In this case, it is preferable that the second fluid pipe 21 is disposed at a position that does not block the ultrasonic propagation path on the fluid space 29. That is, in front of the surface to be irradiated with the ultrasonic waves of the transducer 23, and is formed along the edge of the surface to be irradiated with the ultrasonic waves.

In the fluid supply device 10 described above, the circulation path 30 is connected to the first circulation duct 31 and the second circulation duct 31 in the section between the treatment head 20 and the first pump 43, And may include a channel 32. The circulation path 30 may include a third circulation conduit 33 and a fourth circulation conduit 34 in a section between the treatment head 20 and the second pump 44. A fluid distributor 45 may be installed at the starting point of the first and second circulation ducts 32 and a fluid merger 46 may be installed at the end of the third and fourth circulation ducts 34. The fluid distributor 45 may be a 3-way solenoid valve, depending on the embodiment. The fluid distributor 45 may be electrically connected to the controller 50. The control unit 50 causes the first fluid 35 to flow into the treatment head 20 through the first circulation duct 31 or to the treatment head 20 through the second circulation duct 32 . The first sensor 41 may be installed on the first circulation conduit 31 and the second sensor 42 may be installed on the third circulation conduit 33 depending on the embodiment. In this embodiment, the second circulation conduit 32 is connected to the second inlet 26, and the fourth circulation conduit 34 is connected to the second outlet 28. A fluid reservoir 60 may be additionally provided between the first pump 43 and the second pump 44 on the circulation path 30 according to the embodiment. In addition, the fluid reservoir 60 may further include a cooler capable of cooling the first fluid 35.

The operation of the cooling device included in the fluid supply device 10 according to the embodiment of the present invention will be described.

The fluid flowing through the circulation path (30) includes the first fluid (35) and the second fluid (36). The first fluid 35 refers to the fluid circulating through the circulation path 30 through the first circulation duct 31, the fluid space 29 and the third circulation duct 33 and the second fluid 36 refers to the second Refers to a fluid circulating through the circulation path (30) through the circulation duct (32), the second fluid pipe (21), and the fourth circulation duct (34). The circulation path 30 including the first circulation duct 31, the fluid space 29 and the third circulation duct 33 is referred to as a first path and the second circulation duct 32, The circulation path 30 including the pipe 21 and the fourth circulation duct 34 is referred to as a second path. The first fluid 35 then circulates through the first path and the second fluid 36 circulates through the second path.

When the treatment head 20 performs the treatment, the fluid distributor 45 operates to cause the fluid flowing through the first path to flow through the second path. During treatment, the first fluid 35 should not circulate in the fluid space 29. The ultrasonic irradiation can not be smoothly performed and the treatment may become difficult. Thus, during treatment, the first fluid 35 must remain in the fluid space 29. However, since the transducer 23 generates heat while irradiating the ultrasonic waves, the temperature of the first fluid 35 which is not circulated is increased. Such a temperature rise may damage the transducer 23 and cause a burn to the patient to be treated. There is a problem that the treatment time is increased because the treatment must be stopped in order to lower the elevated temperature inside the container 22.

The fluid supply apparatus 10 provided with the cooling device according to the embodiment of the present invention can continuously circulate the second fluid 36 through the pipe 21 for the second fluid even during the treatment, And the first fluid 35 staying in the fluid space 29, so that the temperature rise of the first fluid 35 can be suppressed or slowed down. This allows the treatment to be carried out continuously, thereby increasing the treatment time. Depending on the embodiment, the second fluid 36 may flow through the second fluid pipe 21 after being cooled by the cooler in the fluid reservoir 60. In this case, since the temperature difference between the second fluid 36 and the first fluid 35 is large, the cooling effect of the first fluid 35 is further increased.

Depending on the embodiment, the fluid reservoir 60 may further include an air eliminator to remove air from the first fluid 35. When bubbles or the like are present in the first fluid 35, ultrasonic waves may be reflected and the transducer 23 may be damaged. Therefore, it is necessary to remove the air of the fluid circulating through the circulation path 30 through the air eliminator.

According to an embodiment, the fluid supply device 10 may further include a fifth circulation conduit connecting the first circulation conduit 31 and the fluid reservoir 60. A relief valve 70 may be provided on the fifth circulation line. The relief valve 70 is a valve or a safety valve for spraying the pressure. When the pressure of the first fluid 35 on the first circulation conduit 31 becomes equal to or higher than a predetermined pressure, the relief valve 70 is ejected into the fifth circulation conduit, 20). The treatment head 20 is expensive and can be protected by a simple structure such as the relief valve 70, which is economical.

The treatment head 20 for a HIFU according to the embodiment of the present invention includes a container 22 at one end and a body 22 having a second inlet 26 and a second outlet 28 for the second fluid 36, (24).

The transducer 23 may include a transducer 23 installed inside the body 24 to emit ultrasonic waves.

Further, it may include a pipe 21 for the second fluid. The second fluid pipe 21 may be disposed at a position that does not block the ultrasonic propagation path on the fluid space 29 between the container 22 and the transducer 23. The second fluid pipe 21 may be provided in front of the surface of the transducer 23 irradiated with the ultrasonic waves and may be formed along the edge of the surface irradiated with the ultrasonic waves. According to the embodiment, the second fluid pipe 21 may be formed in the shape of protrusions and recesses so that the area in contact with the first fluid 35 is increased. One end of the pipe 21 for the second fluid may be connected to the second inlet 26 and the other end may be connected to the second outlet 28.

The body 24 may further include a first inlet 25 and a first outlet 27 for the first fluid 35.

In some embodiments, the first fluid 35 and the second fluid 36 may be water. In addition, the second fluid 36 has a lower temperature than the first fluid 35.

On the other hand, an embodiment of the ultrasonic medical device according to the present invention is a medical device which may include the fluid supply device 10 described above or the treatment head 20 described above. Any medical device to which the fluid supply device 10 or the treatment head 20 of the above-described embodiment can be applied is acceptable. Since the ultrasonic medical device itself is well known in the art, a detailed description thereof will be omitted.

The treatment head 20 equipped with the above-described cooling device is advantageous particularly when the container 22 containing the medium is small. That is, if the container 22 is small, a small amount of medium can not enter. Therefore, the temperature of the medium is rapidly increased due to the heat generated by the transducer 23. In the case of the treatment head 20 using such a small container, If the above-described cooling device is provided, the temperature rise can be effectively suppressed, which is advantageous.

While the present invention has been described in connection with what is presently considered to be practical and exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
