Description

Technical Field

[0001] The utility model relates to the technical field of prostatitis treatment, in particular to a transrectal ultrasonic treatment head for prostatitis treatment. Background Art

[0002] In the treatment of chronic prostatitis, the presence of the blood-prostate barrier (BPB) limits the entry of antibiotics into the prostate tissue, especially the prostate gland ducts, through the blood, resulting in low drug concentrations in the prostate tissue, making it difficult to completely kill pathogenic microorganisms.

[0003] Research has shown that the acoustic radiation force generated by ultrasound irradiation can open the body's biological barriers and increase the osmotic exchange of substances between blood and tissues. For prostate tissue, low-intensity ultrasound irradiation can open the prostate's biological barriers and increase drug concentrations in the prostate. However, because the prostate is located between the bladder and rectum, its anatomical position is posterior. Traditional transabdominal irradiation is long and, when reaching the deep prostate, the acoustic energy attenuates, resulting in poor therapeutic effects. The transrectal approach, on the other hand, allows for close-range irradiation, reduces energy attenuation, and makes it easier to achieve therapeutic effects. However, the existing transrectal approach makes it difficult to fully align the radiation surface with the prostate, preventing effective treatment.

[0004] Therefore, it is necessary to provide a transrectal ultrasound treatment head for treating prostatitis to solve the above problems existing in the prior art. Utility Model Content

[0036] like Figures 1-11As shown, an embodiment of the present invention provides a transrectal ultrasound treatment head 10 for treating prostatitis, comprising a housing 1, a base 2, and an ultrasonic transducer 3. The interior of the housing 1 accommodates the base 2 and the ultrasonic transducer 3. The base 2 supports the ultrasonic transducer 3. The ultrasonic transducer 3 converts electrical energy into mechanical vibrations, thereby generating ultrasonic waves. These waves penetrate the rectal wall and are transmitted to the prostate tissue. The inflamed prostate tissue is irradiated with low-intensity ultrasound, which opens the blood-prostate barrier, thereby increasing drug concentration in the prostate tissue and completely killing pathogenic microorganisms, thereby effectively treating prostatitis.

[0037] The proximal end of the housing 1 has an opening 11. The base 2 is disposed within the inner cavity of the housing 1, and the side surface proximal to the opening 11 forms a predetermined inclined surface 21. The opening 11 is tilted at a predetermined angle. The predetermined angle is the angle between the inclined surface 21 and the axis of the housing 1. The ultrasonic transducer 3 is disposed on the inclined surface 21 of the base 2, spaced apart from the opening 11 to form an inclined treatment surface.

[0038] By designing the side of the base 2 arranged in the inner cavity of the shell 1 close to the opening 11 as an inclined surface 21 with a preset angle, the ultrasonic transducer 3 is arranged on the inclined surface 21 of the base 2, so that the angle between the ultrasonic transducer 3 and the axis of the shell 1 is also a preset angle, so as to form an inclined treatment surface, that is, the angles between the opening 11, the ultrasonic transducer 3 and the inclined surface 21 of the base 2 and the axis of the shell 1 are all designed to be the same preset angle. This inclined treatment surface with a preset angle is designed based on the positional relationship between the rectum and the prostate, and is more suitable for use in the rectal cavity, so that the transrectal ultrasonic treatment head 10 for the treatment of prostatitis of the present invention is inserted into the rectal environment, and can better fit the rectal wall, so that the ultrasonic radiation surface of the ultrasonic transducer 3 is more fully aligned with the prostate, thereby achieving a better therapeutic effect on prostatitis.

[0039] like Figure 1 、 Figure 2 and Figure 4 As shown, in some specific embodiments of the present invention, the ultrasonic transducer 3 is tilted at a preset angle, which is 30° to 75°, preferably 45° to 60°. Compared with horizontal radiation planes and radial radiation planes, not only can the transrectal approach achieve close-range irradiation and reduce energy attenuation, but also when the proximal end of the transrectal ultrasonic treatment head 10 for prostatitis treatment is inserted into the rectal cavity, because the angles between the opening 11, the ultrasonic transducer 3, and the inclined surface 21 of the base 2 and the axis of the housing 1 are all designed to be, for example, 45° to 60°, they can better fit the rectal wall. In addition, the radiation surface of the ultrasonic transducer 3 is 45° to 60°, fully irradiating the prostate tissue, thereby opening the prostate tissue biological barrier, increasing the drug concentration in the prostate tissue, and better treating prostatitis.

[0040] like Figure 1 、 Figure 6 and Figure 10 As shown, in some embodiments of the present invention, the housing 1 is a split structure, specifically consisting of a first housing 12 and a second housing 13. The first housing 12 is designed in a cylindrical shape to facilitate insertion into the rectal environment. The second housing 13 serves as a handle, making it easier for the operator to grip and operate. Furthermore, the diameter of the first housing 12 is larger than the proximal end of the second housing 13, ensuring an adequate ultrasound radiation area and therapeutic effect, while also reducing discomfort for prostatitis patients. An opening 11 is formed at one end of the first housing 12, with the base 2 and ultrasonic transducer 3 located within the inner cavity of the first housing 12. The other end of the first housing 12 is detachably connected to one end of the second housing 13. Exemplarily, a fixing portion 131 is provided at one end of the second housing 13. Specifically, glue is applied to the fixing portion 131, allowing the first and second housings 12, 13 to be bonded together, thereby achieving fixed installation of the first and second housings 12, 13. It should be noted that the housing 1 may also be a one-piece structure, which is not specifically limited here.

[0041] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the transrectal ultrasound treatment head 10 for treating prostatitis further includes an adhesive layer. The adhesive layer is disposed between the inclined surface 21 of the base 2 and the ultrasonic transducer 3. By using the adhesive layer to securely connect the ultrasonic transducer 3 to the inclined surface 21 of the base 2, the ultrasonic transducer 3 and the inclined surface 21 form the same predetermined angle. This not only ensures a secure assembly between the ultrasonic transducer 3 and the inclined surface 21, but also ensures a tight seal between the ultrasonic transducer 3 and the inclined surface 21. In this embodiment, the adhesive layer is formed, for example, by epoxy resin glue, modified epoxy structural glue, or other adhesive.

[0042] like Figure 2 and Figure 5 As shown, in some embodiments of the present invention, the ultrasonic transducer 3 includes a matching layer 31, a piezoelectric layer 32, and a backing layer 33. The matching layer 31, piezoelectric layer 32, and backing layer 33 are sequentially arranged in a direction away from the opening 11 of the housing 1. Specifically, the overall shape of the ultrasonic transducer 3 is cylindrical. The combination of the matching layer 31, piezoelectric layer 32, and backing layer 33 provides impedance matching and sealing. Polyurethane glue, epoxy resin glue, or 704 glue is used to seal the entire ultrasonic transducer 3.

[0043] Specifically, the piezoelectric layer 32 is preferably a piezoelectric ceramic wafer. This utilizes the inverse piezoelectric effect of the piezoelectric ceramic wafer, whereby the wafer deforms when voltage is applied, thereby generating ultrasonic waves. Examples of piezoelectric ceramic wafer materials include iron-barium-manganese-calcium-modified lead zirconate titanate (P4 piezoelectric ceramic), hard lead zirconate titanate (P8 piezoelectric ceramic), and 1-3 piezoelectric composite materials. The ultrasonic transducer 3 in this embodiment utilizes a thickness vibration mode. It should be understood that the thickness vibration mode refers to vibrations in the thickness direction of the piezoelectric ceramic wafer, with the vibration direction aligned with the electric field. This mode exhibits high frequency, low coupling, and high transmittance. The matching layer 31 optimizes the transmission efficiency of sound waves between different media, reduces reflection and scattering, and improves the efficiency of ultrasonic wave transmission. Specifically, the thickness of the matching layer 31 is preferably an odd multiple of 1 / 4 wavelength, utilizing the phase difference of the sound wave to achieve optimal acoustic impedance matching. The acoustic impedance coefficient of the matching layer 31 is preferably the geometric mean of the piezoelectric ceramic wafer and human skin, thereby reducing reflection of sound waves between different media. The backing layer 33 is used to absorb the excess ultrasonic energy generated by the ultrasonic transducer 3, reduce reflection, and improve resolution and directivity. Specifically, the backing layer 33 is made of rubber.

[0044] like Figure 2 and Figure 5 As shown, in some embodiments of the present invention, the ultrasonic transducer 3 further includes foam 34. Foam 34 is disposed on the side of the piezoelectric layer 32. By placing foam 34 on the side of the piezoelectric layer 32, the transducer's vibration boundary condition is set to free vibration, thereby improving output efficiency. Specifically, the thickness of foam 34 is preferably 0.5 to 1 mm.

[0045] like Figure 2 、 Figure 3 、 Figure 7 and Figure 9 As shown, in some embodiments of the present invention, the base 2 is provided with a signal channel 22, a water inlet channel 23, and a water outlet channel 24. The signal channel 22 is used to connect to the electrical cable. The water inlet channel 23 is connected to the water inlet pipeline. The water outlet channel 24 is connected to the water outlet pipeline. Specifically, the signal channel 22, the water inlet channel 23, and the water outlet channel 24 are disposed within the inner cavity of the first housing 12.

[0046] like Figure 2 、 Figure 5 and Figure 9As shown, in some embodiments of the present invention, the ultrasonic transducer 3 further includes a connector 35. The connector 35 is disposed at one end of the signal channel 22 near the opening 11 and is connected to the cable. Specifically, the cable passes through the other end of the second housing 13 and extends toward the opening 11 to the signal channel 22 in the first housing 12 and connects to the connector 35 along the signal channel 22. Exemplarily, the connector 35 is a lead, which is connected to the cable to transmit signals from the external circuit to the electrodes of the ultrasonic transducer 3, allowing the ultrasonic transducer 3 to operate normally.

[0047] like Figure 1 、 Figure 3 and Figure 8 As shown, in some embodiments of the present invention, the transrectal ultrasonic treatment head 10 for treating prostatitis further includes a first lumen 25 and a second lumen 26. The first lumen 25 and the second lumen 26 are both arranged on the side of the base 2 away from the opening 11. The first lumen 25 is connected to the water inlet channel 23. The second lumen 26 is connected to the water outlet channel 24. By providing the first lumen 25 and the second lumen 26, which are respectively connected to the water inlet channel 23 and the water outlet channel 24, the water inlet pipeline is installed in the first lumen 25 and the water outlet pipeline is installed in the second lumen 26, so that the water inlet and water outlet do not interfere with each other, the stability of the water flow is improved, and the cross-sections of the first lumen 25 and the second lumen 26 can be designed according to specific needs to meet the needs of water inlet and water outlet.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the transrectal ultrasound treatment head 10 for treating prostatitis further includes a mounting member 4. The mounting member 4 is disposed within the inner cavity of the housing 1 and near the distal end of the housing 1. Specifically, the mounting member 4 is disposed within the inner cavity of the second housing 13 and near the other end of the second housing 13. It should be noted that the number of mounting members 4 should be specifically designed based on the length of the second housing 13.

[0049] like Figure 2 and Figure 11 As shown, in some embodiments of the present invention, the mounting member 4 is provided with a signal through-hole 41, a water inlet through-hole 42, and a water outlet through-hole 43. The electrical cable, the water inlet pipe, and the water outlet pipe are respectively passed through the signal through-hole 41, the water inlet through-hole 42, and the water outlet through-hole 43 and extend along the direction of the opening 11. Since the second shell 13 is held as a handle and is longer than the first shell 12, the signal through-hole 41, the water inlet through-hole 42, and the water outlet through-hole 43 of the mounting member 4 are designed in the inner cavity of the second shell 13 to provide routing channels for the electrical cable, the water inlet pipe, and the water outlet pipe, respectively, thereby optimizing the internal space layout of the shell 1 and making the internal space orderly.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the transrectal ultrasound treatment head 10 for treating prostatitis further includes a connector 5. The connector 5 is disposed at the distal end of the housing 1. Specifically, the connector 5 is a waterproof lock. By snapping the waterproof lock into the hole at the other end of the second housing 13, cables, water inlet and outlet pipes, and other wiring are routed through the waterproof lock and extended toward the opening 11. This effectively prevents moisture, dust, and other particulate matter from intruding into the interior of the housing 1, securely securing the wiring to prevent loosening or displacement, and facilitating maintenance and replacement.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the transrectal ultrasonic treatment head 10 for treating prostatitis further includes a covering film 6. The covering film 6 is sleeved on the proximal end of the shell 1. The proximal end of the shell 1 is covered by the covering film 6, so that the transrectal ultrasonic treatment head 10 for treating prostatitis plays a sealing role when used to treat prostatitis, and the covering film 6 is disposable, avoiding cross infection and ensuring cleanliness and hygiene. Specifically, the covering film 6 is sleeved on the first shell 12 and part of the second shell 13. It should be noted that the covering film 6 should cover as much of the range of the second shell 13 as possible, so that the proximal end of the transrectal ultrasonic treatment head 10 for treating prostatitis inserted into the rectal cavity can be ensured to be sleeved with the covering film 6, ensuring cleanliness and hygiene and avoiding cross infection. Exemplarily, the covering film 6 is made of silicone, latex or plastic.

[0052] like Figure 1 、 Figure 2 and Figure 6 As shown, in some embodiments of the present invention, the transrectal ultrasonic treatment head 10 for treating prostatitis further includes a seal 7. The seal 7 is sleeved on the outside of the covering film 6 to fasten the covering film 6 to the outside of the housing 1. By arranging the seal 7 on the outer surface of the covering film 6, the seal 7 fastens the covering film 6 to the proximal end of the housing 1, so that the degassed water flowing out through the water inlet channel 23 into the gap between the ultrasonic transducer 3 and the housing 1 does not flow to the outside. Specifically, the seal 7 uses a double-layer rubber sealing ring, and both of the double-layer sealing rings are O-type, which can effectively prevent the covering film 6 from leaking during the treatment process. The double-layer sealing ring is disposable to avoid cross infection and is clean and hygienic.

[0053] Specifically, a recess 121 is provided on the first housing 12. The covering membrane 6 is sleeved over the first housing 12 and a portion of the second housing 13. The rubber sealing ring is sleeved over the covering membrane 6 and located within the recess 121. This allows the rubber sealing ring to more securely secure the covering membrane 6 over the first housing 12 and a portion of the second housing 13. This allows the proximal end of the transrectal ultrasonic treatment head 10 for treating prostatitis to form a sealed water sac cavity when in use.

[0054] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the transrectal ultrasound treatment head 10 for treating prostatitis further includes a temperature sensor 8. The temperature sensor 8 is disposed within the cavity at the proximal end of the housing 1, near the ultrasonic transducer 3. During operation, the ultrasonic transducer 3 converts electrical energy into acoustic energy, with an electrical-to-acoustic conversion efficiency generally ranging from 30% to 70%. The remaining energy is converted into heat. Therefore, over extended periods of operation, the proximal end of the transrectal ultrasound treatment head 10 for treating prostatitis may generate heat, potentially damaging the rectum. By disposing the temperature sensor 8 within the inner cavity of the first housing 12, real-time temperature acquisition and monitoring are performed, thereby protecting the rectum. Exemplarily, the temperature sensor 8 utilizes a thermocouple, which offers advantages such as a wide measurement range, fast response speed, high accuracy, high temperature and pressure resistance, and strong anti-interference capabilities. Of course, the temperature sensor 8 in this embodiment may also utilize other types of temperature measurement devices.

[0055] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the transrectal ultrasound treatment head 10 for treating prostatitis further includes a magnetic positioning sensor 9. The magnetic positioning sensor 9 is disposed inside the housing 1 and close to the proximal end of the housing 1. By arranging the magnetic positioning sensor 9 close to the proximal end of the housing 1, when the transrectal ultrasound treatment head 10 for treating prostatitis is used for treatment, accurate positioning is achieved, precise irradiation is achieved, and a good treatment effect is achieved. It should be noted that the magnetic positioning sensor 9 should be as close as possible to the proximal end of the transrectal ultrasound treatment head 10 for treating prostatitis, so that the portion of the transrectal ultrasound treatment head 10 for treating prostatitis that is inserted into the rectal cavity can be accurately positioned, and the problem of too many proximal components being difficult to place is avoided, and wiring is convenient.

[0056] It should be noted that the "proximal end" in the embodiment of the present invention refers to the end of the transrectal ultrasound treatment head 10 for treating prostatitis close to the prostate tissue, and the "distal end" refers to the end opposite to the proximal end, that is, the end close to the surgical operator.

[0057] In summary, to address the technical problem of the prior art that the radiation surface is difficult to fully align with the prostate, the present invention provides a transrectal ultrasound treatment head for the treatment of prostatitis. By designing the side of the base disposed in the inner cavity of the shell near the opening as an inclined surface with a preset angle, and the ultrasonic transducer being disposed on the inclined surface of the base, the angle between the ultrasonic transducer and the axis of the shell is also a preset angle, thereby forming an inclined treatment surface. That is, the angles between the opening, the ultrasonic transducer, and the inclined surface of the base and the axis of the shell are all designed to be the same preset angle. This inclined treatment surface with a preset angle is more suitable for use in the rectal cavity, so that when the transrectal ultrasound treatment head for the treatment of prostatitis of the present invention is inserted into the rectum, it can better fit the rectal wall, so that the ultrasonic radiation surface of the ultrasonic transducer is more fully aligned with the prostate, thereby achieving a better treatment effect. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial utilization value.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
