Description

Dual-frequency ultrasonic probe and puncture device

Technical Field

The present invention relates to the technical field of medical equipment, and in particular to a dual-frequency ultrasonic probe and a puncture device.

Background technique

Puncture technology has a wide range of application scenarios in clinical applications. It is often used in scenarios such as cytological and histological diagnosis, drainage of fluid accumulation, nerve block and analgesia to help doctors provide targeted treatment to the patient's lesions and enable the patient to recover.

In the prior art, puncture technology often uses ultrasound to guide puncture, so that the puncture needle can accurately point to the target tissue, thereby improving the accuracy of puncture and the quality of imaging. In addition, the application of ultrasound in puncture technology mainly covers ultrasonic imaging and color Doppler. Among them, the principle of ultrasonic imaging is based on sending high-frequency sound wave pulses to human tissues, receiving and processing the reflected sound wave signals, and converting them into electrical signals. These signals are processed and analyzed to generate high-resolution real-time images; color Doppler technology is an extension of ultrasonic imaging, which is used to display information such as blood flow, helping doctors observe blood flow speed and direction and calculate the real-time distance between the transducer and tissues such as blood vessels in the body, thereby avoiding damage to blood vessels and other tissues during puncture and drainage.

However, the existing ultrasound probes have relatively simple specifications and operating frequencies. The simple specifications result in problems such as high imaging quality but small imaging range or low imaging quality but large imaging range. In addition, the simple operating frequency requires the probe to be replaced during surgery to obtain corresponding imaging and distance information to meet surgical needs, which greatly increases the patient's pain.

Example 1

The present embodiment provides a dual-frequency ultrasonic probe, as shown in FIGS. 1 to 4 , comprising a housing 1, a mounting member 2 and a detection structure 3, wherein the housing 1 has a housing cavity with an opening at the proximal end; the mounting member 2 is rotatably disposed in the housing cavity and is located at the distal end of the housing cavity, a mounting portion 21 is provided on the mounting member 2, the mounting portion 21 has a mounting surface 211, and the mounting surface 211 is perpendicularly disposed to both end surfaces of the mounting member 2; the detection structure 3 comprises a first detection member 31 and a second detection member 32, the first detection member 31 is disposed on the mounting surface 211, and the second detection member 32 is disposed on the end surface at the distal end of the mounting member 2, and both the first detection member 31 and the second detection member 32 are suitable for being electrically connected to an external system; under the action of an external force, the mounting member 2 is suitable for driving the detection structure 3 to rotate in the housing cavity, so that the detection structure 3 has the image information of the lesion within the circumferential range of the housing 1 detected by the first detection member 31 during the rotation process, and the second detection member 32 is suitable for detecting the distance information between the distal end of the housing 1 and the lesion within the axial range.

The dual-frequency ultrasonic probe of the above structure is provided with a mounting member 2 arranged in the accommodating member 1 and a detection structure 3 capable of realizing the detection function arranged on the mounting member 2. The mounting member 2 is a backing layer structure in this embodiment, wherein the accommodating member 1 has a accommodating cavity, and an opening is arranged at the proximal end of the accommodating cavity, so that the mounting member 2 can be installed in the accommodating cavity through the opening, and the mounting member 2 can rotate in the accommodating cavity under the action of an external force. In addition, a mounting portion 21 is provided on the mounting member 2, and the mounting portion 21 is a mounting groove in this embodiment, and the mounting portion 21 has a mounting groove with the mounting member 21. 2, the mounting surfaces 211 are vertically arranged on the end surfaces of both sides of the mounting groove, and the mounting surfaces 211 are specifically the bottom surfaces of the mounting grooves. The detection structure 3 specifically includes a first detection member 31 and a second detection member 32, wherein the first detection member 31 is arranged on the mounting surface 211, and the second detection member 32 is arranged on the end surface of the far end of the mounting member 2, so that the first detection member 31 and the second detection member 32 are vertically arranged, and the first detection member 31 and the second detection member 32 are both electrically connected to the external system, so that the first detection member 31 and the second detection member 32 can respectively detect the two directions of the accommodating member 1.

At the same time, the detection structure 3 has a detection state, that is, when the external force drives the mounting member 2 to rotate in the accommodating cavity, the first detection member 31 and the second detection member 32 are driven by the mounting member 2 to rotate in the accommodating cavity, so that the first detection member 31 can detect the image information of the lesion within the circumferential range of the accommodating member 1 during the rotation process, and the second detection member 32 can use the Doppler effect to detect the distance information between the distal end of the accommodating member 1 and the lesion within the axial range during the rotation process, thereby improving the imaging range of the dual-frequency ultrasonic probe through the first detection member 31, and enriching the imaging information of the dual-frequency ultrasonic probe through the second detection member 32, that is, the dual-frequency ultrasonic probe provided in this embodiment can simultaneously obtain the peripheral image of the lesion tissue and the distance between the probe and the lesion tissue, blood vessels and nerves in the body through the detection structure 3, so that there is no need to replace the probe to obtain the corresponding imaging during the operation, thereby greatly reducing the pain of the patient during the operation.

In addition, the distal end of the container 1 is configured as a closed elliptical structure, so that when the container 1 is extended into the human body under the action of external force, the closed elliptical structure can prevent tissue fluid in the human body from infiltrating into the accommodating cavity and then damaging the detection structure 3 disposed in the accommodating cavity. In the present embodiment, the container 1 is an ultrasonic sheath, and its acoustic characteristics can allow ultrasonic signals to pass through with a lower attenuation rate.

In the dual-frequency ultrasonic probe provided in this embodiment, as shown in FIG. 1 and FIG. 2 , both the first detection element 31 and the second detection element 32 use transducers, and the frequency of the first detection element 31 is lower than the frequency of the second detection element 32 .

The dual-frequency ultrasonic probe of the above structure is configured such that both the first detection component 31 and the second detection component 32 are transducers. The transducers can detect the specific image of the diseased tissues, blood vessels and nerves in the human body or the distance between the probe and the tissue by emitting ultrasonic waves and receiving ultrasonic waves rebounded by the diseased tissues, blood vessels and nerves in the human body. Thus, the first detection component 31 and the second detection component 32 can respectively obtain the image information of the diseased tissues, blood vessels and nerves in the human body and the distance information between the probe and these tissues.

At the same time, the frequency of the first detection element 31 is lower than the frequency of the second detection element 32, so that the low-frequency first detection element 31 can obtain image information of the diseased tissue, blood vessels and nerves in the body in a farther circumferential direction, and the high-frequency second detection element 32 can obtain more precise distance information between the probe and tissues such as lesions, thereby enabling the dual-frequency ultrasonic probe to simultaneously obtain large-scale image information of diseased tissues, blood vessels and nerves in the body and precise distance information between the probe and these tissues.

Specifically, the first detection element 31 is set as a low-frequency transducer because low-frequency signals can see farther, and the second detection element 32 is set as a high-frequency transducer because according to the ultrasonic sinusoidal state and the Doppler effect, the higher the frequency, the higher the detection accuracy, and the more subtle blood vessels and nerves can be detected, thereby avoiding damage to blood vessels and nerves during puncture.

In the dual-frequency ultrasonic probe provided in this embodiment, as shown in FIG. 1 to FIG. 4 , the frequency of the first detection element 31 is 12 MHz, and the frequency of the second detection element 32 is 30 MHz.

The dual-frequency ultrasonic probe of the above structure sets the frequency of the first detection element 31 to 12 MHz and the frequency of the second detection element 32 to 30 MHz, so that the frequency of the first detection element 31 is smaller than the frequency of the second detection element 32, so that the first detection element 31 and the second detection element 32 can respectively obtain image information of lesion tissue, blood vessels and nerves in the body and distance information between the probe and these tissues.

The dual-frequency ultrasonic probe provided in this embodiment, as shown in FIG1 , further includes a transmission member 4, at least a distal portion of which is located in the accommodating cavity, the distal end of the transmission member 4 is connected to the proximal end of the mounting member 2, and the proximal end of the transmission member 4 is connected to an external system, so that under the action of the external system, the distal end of the transmission member 4 rotates in the accommodating cavity and drives the mounting member 2 to rotate in the accommodating cavity.

The dual-frequency ultrasonic probe of the above structure has a transmission member 4 disposed in the accommodating cavity through the distal end portion. The transmission member 4 is a transmission tube in this embodiment. The distal end of the transmission member 4 is connected to the proximal end of the mounting member 2 in the accommodating cavity, and the proximal end of the transmission member 4 is connected to the external system outside the accommodating cavity. Therefore, under the action of the external system, the transmission member 4 can drive the mounting member 2 to rotate in the accommodating cavity, and then the mounting member 2 can drive the first detection member 31 and the second detection member 32 to rotate in the accommodating cavity, and the first detection member 31 and the second detection member 32 can respectively obtain image information of the lesion tissue, blood vessels and nerves in the body and distance information between the probe and these tissues. Of course, the proximal end of the transmission member 4 can also be connected to the external system in the accommodating cavity.

Specifically, the mounting member 2 in this embodiment specifically includes a mounting carrier and a backing layer, wherein the mounting carrier is the distal end portion of the transmission member 4, and is an integrally formed structure with the transmission member 4, the mounting portion 21 is a mounting groove opened on the mounting carrier, the backing layer is arranged in the mounting groove, and the mounting surface 211 is a plane of the backing layer exposed in the mounting groove, the plane is vertically arranged to the end face of the mounting carrier, and the first detection member 31 is arranged on the mounting surface 211, and at the same time, the distal end face of the backing layer is parallel to the distal end face of the mounting carrier, so that the distal end face of the backing layer is vertically arranged to the mounting surface 211, and the second detection member 32 is arranged on the distal end face of the backing layer, so that the first detection member 31 and the second detection member 32 are vertically arranged, and finally the first detection member 31 and the second detection member 32 can simultaneously detect the circumferential and axial directions of the mounting member 2.

The dual-frequency ultrasonic probe provided in this embodiment is shown in Figure 1, and the outer peripheral walls of the transmission member 4 and the mounting member 2 are spaced apart from the inner wall of the accommodating cavity to allow the transmission member 4 and the mounting member 2 to rotate in the accommodating cavity under the action of the external system.

The dual-frequency ultrasonic probe of the above structure is arranged so that the outer peripheral walls of the transmission member 4 and the mounting member 2 are spaced apart from the inner wall of the accommodating cavity, so that there is a gap between the outer peripheral walls of the transmission member 4 and the mounting member 2 and the inner wall of the accommodating cavity. Therefore, when the external system acts, the transmission member 4 can drive the mounting member 2 to rotate freely in the accommodating cavity without being blocked by the inner wall of the accommodating cavity.

Specifically, the interval between the outer peripheral wall of the transmission part and the mounting part and the inner wall of the accommodating cavity is set to 0.2 mm, thereby providing space for the transmission part and the mounting part to rotate in the accommodating cavity, and the interval can also ensure the rotational stability of the transmission part and the mounting part in the accommodating cavity without deviating from the center of the circle.

The dual-frequency ultrasonic probe provided in this embodiment, as shown in Figures 1 and 2, has a first detection member 31 having a first ground electrode surface 311; it also includes a first connecting member, and the two ends of the first connecting member are electrically connected to the transmission member 4 and the first ground electrode surface 311 respectively, so that the power on the first detection member 31 is transmitted to the transmission member 4 through the first connecting member, and then transmitted to the external system through the transmission member 4.

The dual-frequency ultrasonic probe of the above structure is provided with a first grounding surface 311 and a first connecting member arranged between the first grounding surface 311 and the transmission member 4 by setting the first detecting member 31. The first connecting member is a first cable in this embodiment. The operation of the first detecting member 31 requires the use of electricity, and since the first detecting member 31 is arranged on the mounting surface 211, the first grounding surface 311 cannot be directly electrically connected to the external system. By connecting the two ends of the first connecting member to the transmission member 4 and the first grounding surface 311 respectively, the external system can transmit electricity to the first grounding surface 311, so that the first detecting member 31 can work normally.

The dual-frequency ultrasonic probe provided in this embodiment, as shown in Figures 1 and 2, has a second detection member 32 with a second ground electrode surface; it also includes a second connecting member, and the two ends of the second connecting member are electrically connected to the transmission member 4 and the second ground electrode surface respectively, so that the power on the second detection member 32 is transmitted to the transmission member 4 through the second connecting member, and transmitted to the external system through the transmission member 4.

The dual-frequency ultrasonic probe of the above structure is provided with a second detection member 32 having a second ground electrode surface and a second connecting member arranged between the transmission member 4 and the second ground electrode surface. The second connecting member is a second cable in this embodiment. The second detection member 32 needs to use electricity to work, and because the second detection member 32 is arranged on the mounting surface 211, the second ground electrode surface cannot be directly electrically connected to the external system. By connecting the two ends of the second connecting member to the transmission member 4 and the second ground electrode surface respectively, the external system can transmit electricity to the second ground electrode surface, so that the second detection member 32 can work normally.

The dual-frequency ultrasonic probe provided in this embodiment, as shown in Figures 1 and 2, has a first detection member 31 having a first ground pole surface 311 and a second detection member 32 having a second ground pole surface; it also includes a deposition member 5, and the deposition member 5 is arranged on the outer wall surface of the mounting member 2 and the outer peripheral wall surface of the far end of the transmission member 4, and the deposition member 5 is arranged on at least one of the first ground pole surface 311 and the second ground pole surface, so that the power on at least one of the first detection member 31 and the second detection member 32 is transmitted to the transmission member 4 through the deposition member 5.

The dual-frequency ultrasonic probe of the above structure is provided with a first ground pole surface 311 of the first detection member 31 and a second ground pole surface of the second detection member 32, and a deposition member 5 is provided on the outer wall surface of the mounting member 2 and the outer peripheral wall surface of the distal end of the transmission member 4. The deposition member 5 is a gold-plated layer produced by a magnetron sputtering method in this embodiment, so that the deposition member 5 connects the outer wall surface of the mounting member 2 and the outer peripheral wall surface of the distal end of the transmission member 4 together. In addition, the deposition member 5 is also provided on the first ground pole surface 311, so that the power required for the operation of the first detection member 31 can be transmitted from the external system to the first detection member 31 through the transmission member 4 and the deposition member 5, thereby enabling the first detection member 31 to be operated. The measuring piece 31 can work normally. Of course, the deposition piece 5 can also be set on the second ground surface, so that the power required for the second detecting piece 32 to work can be transmitted from the external system through the transmission piece 4 and the deposition piece 5 to the second detecting piece 32, thereby enabling the second detecting piece 32 to work normally. Alternatively, the deposition piece 5 can also be set on the first ground surface 311 and the second ground surface, so that the power required for the first detecting piece 31 and the second detecting piece 32 to work can be transmitted from the external system through the transmission piece 4 and the deposition piece 5 to the first detecting piece 31 and the second detecting piece 32, thereby enabling both the first detecting piece 31 and the second detecting piece 32 to work normally.

Specifically, when the polar surface of the first detection member 31 transmits power by the transmission member 4 and the deposition member 5, the polar surface of the second detection member 32 transmits power through the second connecting member and the transmission member 4. When the polar surface of the second detection member 32 transmits power by the transmission member 4 and the deposition member 5, the polar surface of the first detection member 31 transmits power through the first connecting member and the transmission member 4. When the polar surfaces of both the first detection member 31 and the second detection member 32 transmit power by the transmission member 4 and the deposition member 5, there is no need to use the first connecting member or the second connecting member. This can avoid the existence of welding points, save the use of cables, and finally reduce the volume of the dual-frequency ultrasonic probe.

Specifically, the deposition member 5 is a 50nm Cr layer and a 200nm Au metal layer deposited by magnetron sputtering technology, wherein the Cr metal layer mainly functions as an adhesion layer.

The dual-frequency ultrasonic probe provided in this embodiment, as shown in Figures 1 and 2, has a transmission member 4 with a transmission channel with openings at both ends; the first detection member 31 also has a first positive electrode surface, and the second detection member 32 also has a second positive electrode surface; it also includes a transmission member 6, the first positive electrode surface and the second positive electrode surface are both electrically connected to the end of the transmission member 6, and the external system is electrically connected to the other end of the transmission member 6, so that image information and distance information can be transmitted to the external system through the transmission member 6.

The dual-frequency ultrasonic probe of the above structure is provided with a transmission channel on the transmission member 4, a first positive electrode surface and a second positive electrode surface arranged on the first detection member 31 and the second detection member 32, and a transmission member 6 arranged between the external system and the detection structure 3. The transmission member 6 in this embodiment is a two-core transmission cable, wherein the first positive electrode surface and the second positive electrode surface are both electrically connected to one end of the transmission member 6, and the external system is electrically connected to the other end of the transmission member 6, and the part between the two ends of the transmission member 6 is arranged in the transmission channel, so that the external system can transmit electricity to the first positive electrode surface and the second positive electrode surface respectively through the transmission member 6, and the first detection member 31 and the second detection member 32 can transmit the image information of the lesion tissue, the blood vessels and nerves in the body and the distance information between the probe and these tissues to the external system through the transmission member 6.

The dual-frequency ultrasonic probe provided in this embodiment, as shown in Figures 2 and 3, is provided with a yield portion 22 connected to the transmission channel on the mounting surface 211. After one end of the transmission component 6 is respectively connected to the first positive electrode surface and the second positive electrode surface, part of the transmission component 6 is arranged in the yield portion 22, and the other end of the transmission component 6 passes through the transmission channel to be connected to the external system.

The dual-frequency ultrasonic probe of the above structure has a yielding portion 22 provided on the mounting surface 211. The yielding portion 22 is a yielding groove in the present embodiment. After one end of the transmission component 6 is respectively connected to the first positive electrode surface and the second positive electrode surface and the other end is connected to the external system, the portion between the two ends of the transmission component 6 can be arranged in the yielding portion 22 and the transmission channel, thereby avoiding in physical space that when one end of the transmission component 6 is respectively connected to the first detection component 31 and the second detection component 32, it will affect the connection between the first detection component 31 and the second detection component 32 and the mounting component 2.
