Technical Field
The invention relates to the technical field of ultrasonic equipment, in particular to an ultrasonic probe, an ultrasonic surgical device and ultrasonic surgical equipment.
Background
An ultrasound probe is a common medical detection device in which an ultrasound transducer, otherwise referred to as an ultrasound assembly, is arranged, the basic principle being that the housing of the ultrasound probe is in good contact with the skin surface of the human body via a coupling agent, sound waves propagate from the ultrasound transducer into the soft tissue in the form of pulse beams, the sound waves are partly absorbed by the tissue and partly reflected back to the ultrasound transducer to be detected. The ultrasound probe is capable of instantaneously processing many pulsed beams to produce a real-time image for diagnosis. The shorter the wavelength of the acoustic wave, the higher the frequency and the higher the resolution of the image obtained, and therefore, a high-frequency ultrasound probe is generally used to obtain a clear ultrasound image. But the high frequency pulses are attenuated more in the soft tissue, which means that the high frequency sound waves may not be reflected back sufficiently from the deep structures for detection by the ultrasound transducer.
For certain locations inside the human body, such as tumor sites, it is generally not possible to reach through the natural lumen of the human body (e.g., esophagus, rectum, etc.), so that ultrasonic detection can only be performed on the skin surface. In the prior art, the image of deep tissue is usually obtained by reducing the frequency of sound waves, but the resolution of the deep image is reduced, so that the problem that the percutaneous ultrasound is difficult to obtain a deep high-definition image is caused. Thus, the relationship between the puncture point and the tumor and the surrounding tissues are difficult to accurately judge.

Detailed Description
Embodiments of the present invention will be described below with reference to the accompanying drawings. Fig. 1 is a schematic view of the external shape of an ultrasonic surgical apparatus according to an embodiment of the present invention, and fig. 2 is a schematic view of an exploded state of an ultrasonic surgical device according to an embodiment of the present invention. In the following description, the upper left side in fig. 1 and 2 is the distal end and the lower right side is the proximal end, according to the perspective of the user of the device, i.e., the surgeon.
The ultrasonic surgical apparatus 100 includes an ultrasonic surgical device 200 and a handle 300. The ultrasonic surgical device comprises an ultrasonic probe 1, a channel needle 2 and a three-way pipe 4. The ultrasound probe 1 is arranged in a hollow access needle 2. The access needle 2 serves as a puncture during surgery. In some organ punctures, such as liver punctures, severe bleeding is easily initiated if the outer diameter of the puncture needle exceeds 3mm. In the existing endoscope technology, a plurality of channels are usually arranged in an endoscope, and for liver puncture, if an existing ultrasonic probe is arranged and an ablation needle is arranged at the same time, the outer diameter of the puncture needle is difficult to control within 3mm.
In this regard, in the embodiment of the present invention, there is provided an ultrasonic probe 1, and a probe housing of the ultrasonic probe 1 includes an ultrasonic assembly mounting position 11 and an elongated groove 12, and an ultrasonic assembly 13 is provided in the ultrasonic assembly mounting position 11. The ultrasonic assembly 13 is an element for generating ultrasound, includes an ultrasonic probe transducer, and is an element that emits ultrasound and receives return sound waves.
Fig. 3 is a schematic diagram of a connection state of an ultrasonic assembly and a flexible circuit board according to an embodiment of the present invention. As shown in fig. 3, the ultrasonic assembly 13 is connected to a flexible wiring board 14. In the ultrasonic surgical apparatus 100, the flexible wiring board 14 serves as a wire of the ultrasonic assembly 13, and an electrical connection between the ultrasonic assembly 13 and an ultrasonic main body (not shown in the drawing) is achieved.
Fig. 4 is a schematic view of an ultrasonic probe of an embodiment of the present invention. As shown in fig. 4, the ultrasound probe 1 needs to be able to be disposed within the access needle 2, i.e. the ultrasound probe 1 is of a very elongated shape. An ultrasonic assembly 13 is arranged in the ultrasonic assembly mounting position 11, and a flexible circuit board 14 is arranged in the long groove 12. When placed in the ultrasonic probe housing, the flexible circuit board 14 is attached to the inner surface of the long groove 12, namely the groove bottom, and the outer surface of the long groove 12 is attached to the inner wall of the channel needle 2. The flexible circuit board 14 is selected because it has a small thickness, typically within 0.5mm, and thus occupies little space within the access needle 2.
The long groove 12 is adopted so that the flexible circuit board 14 can be accommodated without arranging a separate channel in the channel needle 2, and enough space is formed between the inner surface of the long groove 12 and the channel needle 2, so that after the ultrasonic probe 1 is arranged in the channel needle 2, a strip-shaped piece with an elongated shape required by an operation can be arranged. For example, in ablation procedures, a flexible ablation needle 3 may be placed into the access needle. In another example, the tissue may be irrigated and a water tube may be placed into the access needle. In the present embodiment, the insertion of the ablation needle 3 will be described as an example.
The distal end of the channel needle 2 is a sharp point, so that the channel needle 2 can penetrate into the skin, namely the ultrasonic probe 1 enters the human body through the skin for ultrasonic detection, and does not pass through the cavity of the human body, thereby belonging to percutaneous ultrasonic detection. An opening 21 is provided near the distal end of the access needle 2, and the width of the opening 21 is such that it occupies a range of 120 ° in the circumferential direction of the access needle 2, and the length thereof is required to be longer than the acoustic window of the ultrasound probe 1. And since the ablation needle 3 is also disposed in the access needle 2 and the ablation end 31 is to protrude from the opening 21, the length of the opening 21 also leaves a certain protruding space for the ablation end 31.
The proximal end of the access needle 2 is connected to the outlet 411 of the tee 4. Tee 4 includes a first straight tube 41 and a second straight tube 42. The ablation needle 3 is a flexible ablation needle, and the ablation end 31 enters the access needle 2 from the second inlet 421 and then protrudes from the opening 21. The opening at the groove top of the long groove 12 is oriented to the upper right in fig. 2, and the thickness of the ultrasonic assembly mounting position 11 (the dimension in the lower left to upper right direction in fig. 2, that is, the dimension in the groove-top direction of the long groove 12) is larger than the depth of the long groove 12. A guiding inclined plane 111 is arranged at the position of the ultrasonic assembly mounting position 11 near the long groove 12, so that the flexible ablation needle 3 can conveniently advance in the channel needle 2, and the ablation end 31 can smoothly extend out of the opening 21. The ablation needle tail 33 is located outside the second straight tube 42 so as to form a certain angle with the ablation needle body 32, and the ablation needle body 32 forms a certain angle with the ablation end 31, so that the ablation end 31 can swing left and right by manipulating the ablation needle tail 33, and the flexibility of the ablation operation is improved.
The ultrasonic probe 1 in the embodiment of the invention can be combined with an outer needle of the coaxial needle, namely, the outer needle of the coaxial needle is used as the channel needle 2, the outer needle is also provided with an opening at the front end, the inner needle matched with the coaxial needle firstly establishes a channel, and then the inner needle is pulled out and inserted into the ultrasonic probe 1 to obtain an in-vivo ultrasonic image.
According to the technical scheme of the embodiment of the invention, the ultrasonic probe is of an elongated shape and can be placed in the hollow channel needle, the probe shell is provided with the long groove, and the flexible circuit board is placed in the long groove, so that the occupation of the wires of the ultrasonic assembly to the space in the channel needle is reduced. Therefore, the device can still have small radial dimension when an ablation needle or a water pipe is needed to be placed in the channel needle, is suitable for surgical occasions needing finer puncture needles, and can obtain high-definition ultrasonic images of tissues deep in a human body.
The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives can occur depending upon design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
