Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic endoscopes, in particular to a multifunctional ultrasonic endoscope and a working method thereof. Background Art

[0002] Ultrasound endoscope is a technology that continuously advances and expands its functions. It fills the gap of some special indications that cannot be covered by ordinary endoscopes, surface ultrasound and CT. Sector-scanning ultrasound endoscope can observe and monitor the direction and depth of the puncture needle in real time, making FNA under the guidance of endoscopic ultrasound possible. The application of color Doppler and energy Doppler avoids the possibility of puncturing blood vessels, and ultrasound-guided fine needle aspiration biopsy technology increases the application of longitudinal ultrasound endoscope to the examination of diseases such as upper gastrointestinal and pancreatic tumors. Endoscopic ultrasound-guided gastrointestinal cyst fistula makes drainage more accurate and reduces the risk of bleeding and perforation. Even very small tumors in the upper gastrointestinal tract can be clearly displayed by endoscopic ultrasound. In addition, endoscopic ultrasound has a good or even accurate judgment on the size and local infiltration range of pancreatic tumors and submucosal lesions, which is difficult to match by other imaging technologies. Nowadays, the clinical application of the three major interventional technologies under the guidance of endoscopic ultrasound: fine needle aspiration cytology under the guidance of endoscopic ultrasound, drainage technology under the guidance of endoscopic ultrasound, and fine needle injection technology under the guidance of endoscopic ultrasound is becoming more and more frequent and extensive.

[0003] For example, a patent document with publication number CN 112842231 B discloses an ultrasonic endoscope, comprising: an endoscope head body, which is arranged on the distal side of the insertion part of the ultrasonic endoscope and is provided with a lifting chamber, wherein the lifting chamber is continuously open at the side surface and the end of the endoscope head body; a convex ultrasonic head, which is arranged at the end of the endoscope head body and can form an ultrasonic scanning plane for transmitting and receiving ultrasonic signals in a direction similar to the side surface; and a lifter, which is arranged in the lifting chamber and is pivotally fixed so as to be rotatable.

[0004] However, in actual use, due to the limitation of its own structure, this structure can only use a simple single ultrasonic probe to complete the ultrasonic endoscope inspection. However, the single ultrasonic probe has a hardware problem of a large inspection blind spot. During the inspection, medical staff often need to constantly control the head of the ultrasonic endoscope and move it inside the patient's body, thereby constantly adjusting the position of the single ultrasonic probe to find the lesion. Such operation results in low efficiency in locating the lesion and may cause unnecessary internal damage to the patient under anesthesia. At the same time, the equipment cannot provide a more stable and limited adjustment auxiliary operation for the entire lens of the ultrasonic endoscope, and cannot meet daily use needs. Therefore, it is urgent to design a multifunctional ultrasonic endoscope and its working method to solve the above problems. Summary of the invention

The rotating inner tube then drives the central rotating seat as a whole inside the sleeve ring seat connected at the other end to rotate and adjust the adaptation angle of the inspection lens group and the central ultrasound probe, so as to quickly dock with the lesion.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The multifunctional ultrasonic endoscope and its working method can make the ultrasonic endoscope device as a whole be used for more efficient inspection and use by arranging a control unit, a connecting head, a guide tube, a spring sheath tube, an air pressure control seat, a conical connecting seat, a central rotating seat, an adjusting ring seat, a movable shaft, a flip cover, an equipment frame, a side ultrasonic probe, an adjusting air bag, a spreading roller, an air uniforming ring tube, a venting tube, a first air control valve, a second positioning pressure ring, a second damping rubber ring, an inspection lens group, a central ultrasonic probe, a conical air delivery groove, an air uniforming ring groove and a delivery tube. In actual use, the staff first connects the central rotating seat as a whole to the control unit through the connecting head, the guide tube and the spring sheath tube as a whole at the back. The control unit is connected at one end of the control unit, and the subsequent control unit can control the spring sheath tube to perform rapid all-round movable adjustment of the center rotating seat at one end, and put the center rotating seat, the sleeve ring seat and the adjustment ring seat into the patient's body as a whole. The inspection lens group on the front of the center rotating seat cooperates with the central ultrasonic probe at one end to perform the lesion inspection operation in the patient's body. At this time, the uniform air ring groove inside the air pressure control seat can also be started synchronously to make it inhale from the delivery pipe, and then evenly deliver the air to the uniform air ring tube on the inner wall of the back of the adjustment ring seat along the conical air delivery groove on the inner wall of the conical seat. The uniform air ring tube can evenly transmit the airflow to each flip cover The regulating airbags on both sides of the inner wall drive the flip covers on the four sides of the adjusting ring seat to rotate and unfold along their respective active axes. At this time, the support roller set at one end of the flip cover can roll and support the surrounding tissues, quickly exposing the side ultrasound probes at the internal equipment frame, and sending the same ultrasound detection signals as the central ultrasound probe to the four sides of the adjusting ring seat, so that the auxiliary inspection lens group and the central ultrasound probe can quickly locate the specific range of the lesion, greatly improving the inspection efficiency of the ultrasound endoscope equipment for lesions. At the same time, the equipment can control the ventilation pipes at the four corners of the inner wall of the adjusting ring seat and the first air control valve to uniformly distribute the air. Part of the air pressure inside the ring tube is sent to the second air control valve of the sleeve ring seat, and then the annular airbag on the inner wall of the sleeve ring seat is inflated to make it gather toward the center, and the first positioning pressure ring on the inner wall of the annular airbag is connected to the second positioning pressure ring in the center of the side of the center swivel seat to lock the center swivel seat inside the sleeve ring seat. The second damping rubber rings at both ends of the side of the center swivel seat can also perform adaptive fitting and damping operations with the first damping rubber rings at both ends of the inner wall of the sleeve ring seat to ensure that when the center swivel seat is performing ultrasonic endoscopic fixed-point inspection, the inspection lens group at one end and the central ultrasonic probe can be in a more secure locking state, which reflects the practicality of the equipment design.

[0020] The multifunctional ultrasonic endoscope and its working method further improve the overall use effect of the equipment through the control unit, connecting seat, plug-in seat, plug connector, guide tube, rotating control seat, conical seat, sleeve ring seat, second air control valve, annular air bag, first positioning pressure ring, first damping rubber ring, limiting inner ring sleeve, rotating inner tube, driving gear ring, bearing seat, micro motor, starting gear, damping rubber pad, pipe groove, pump rack, air control pump, plug-in tube and protective cover. In daily use, the staff can install the control unit and the connecting seat as a whole on the control instrument through the plug-in seat and the plug connector, which is convenient for rapid overall disassembly and cleaning operations later. The rotating control seat and the air pressure control seat are installed between the spring sheath tube and the conical seat. The air pressure control seat can perform continuous charging and discharging air pressure control operations through the uniform air ring groove and the delivery pipe. The rotating control seat can drive the starting gear at one end to rotate by starting the micro motor on the inner bottom wall, and then The inner tube is then driven to engage with the driving tooth ring on the side of one end of the rotating inner tube, driving the rotating inner tube as a whole to rotate and adjust under the limiting sleeve of the inner ring sleeve inside the tapered seat, and the rotating inner tube then drives the central rotating seat as a whole inside the sleeve ring seat connected at the other end to rotate and adjust the adaptation angle of the inspection lens group and the central ultrasonic probe, so as to quickly dock with the lesion, and can also be locked and fixed by the sleeve ring seat sleeved on the outer surface of the central rotating seat. At the same time, the medical device can be inserted at the plug-in tube at the top of the connecting seat on a daily basis, and finally pass through one end of the inspection lens group along the rotating inner tube. The movable protective cover at one end of the plug-in tube can be used for sealing protection, and the pump rack and air control pump at the bottom of the connecting seat can cooperate with the uniform air ring groove and the delivery pipe on the inner wall of the air pressure control seat to perform pressure control operations of extracting and releasing air, so as to realize efficient adjustment of the entire ultrasonic endoscope equipment in the body, and complete the inspection operation of the patient more efficiently, reflecting the comprehensiveness of the equipment design.
