Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an ultrasound instrument and ultrasound probe for interventional surgery. Background Technology

[0002] An ultrasound machine is a medical ultrasound imaging device designed specifically for the operating room environment. It provides clear images of internal organs, blood vessels, diseased tissues, and surgical instruments in real time during surgery, assisting interventional physicians in precise positioning, diagnosis, guidance, and evaluation, thereby greatly improving the safety and success rate of puncture.

[0003] In the current application of ultrasound equipment in puncture surgery, doctors need to place the probe on the patient's puncture site for guidance, while also turning their heads to view the imaging information on the ultrasound equipment. This method, to some extent, distracts the doctor's attention, reduces the efficiency of the puncture, and increases the risk of puncture errors. Summary of the Invention

The ends of the elastic springs away from the moving platform are fixedly connected to the outer side of the movable rack. A slit is formed on the inner wall of the narrow groove away from the movable rack. A fitting piece is slidably connected within the slit. A fitting opening is formed on the side of the fixed rod away from the straight rack. The inner wall of the fitting opening is slidably connected to the outer side of the fitting piece. Two symmetrical springs are fixedly connected to the inner wall of the slit, and the ends of the springs near the fitting piece are fixedly connected to the outer side of the fitting piece.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] The ultrasound instrument and probe for interventional surgery disclosed in this invention are mainly used in scenarios where existing ultrasound instruments cannot allow doctors to simultaneously observe images and operate the probe.

[0024] Reference Figures 1-6An ultrasound device for interventional surgery includes an ultrasound device body 1, a connecting line 2 on the ultrasound device body 1, a rod-type probe 3 at the end of the connecting line 2 away from the ultrasound device body 1, a reserved slot 4 on the ultrasound device body 1, a protective eyeglass 5 inside the reserved slot 4, a head-up display module 8 on the outside of the protective eyeglass 5, a main display screen 7 on the ultrasound device body 1, a signal transmitter 6 on the upper side of the ultrasound device body 1, a frame 10 on the outside of the protective eyeglass 5, the head-up display module 8 including a collimating lens 801 located outside the protective eyeglass 5, a freeform mirror 802 on the side of the collimating lens 801 near the protective eyeglass 5, the freeform mirror 802 and the collimating lens 801 being mounted on the same fixing frame 803, and an LBS laser light source 805 and a signal receiver 804 on the upper side of the fixing frame 803, and a battery 809 on the outside of the frame 10.

[0025] Specifically, the device uses a head-up display module 8 to wirelessly transmit the ultrasound image detected by the rod probe 3 to the collimating lens 801 via a signal transmitter 6. By having the doctor wear protective glasses 5, the doctor can directly see the image of the position detected by the rod probe 3 through the collimating lens 801 while using the rod probe 3. This allows the doctor to analyze the detection image while performing the puncture, reducing the doctor's head turning movements and improving the accuracy and efficiency of the puncture.

[0026] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6In a preferred embodiment, a bracket 806 is bolted to the upper side of the fixing frame 803, a bracket 808 is provided on the outside of the battery 809, and a movable platform 807 is bolted to the bottom of the bracket 808. A notch is provided on the outside of the movable platform 807, and a rotating shaft 810 is rotatably connected to the notch via a bearing. A circular hole is provided on the bracket 806, and the inner wall of the circular hole is bolted to the outside of the rotating shaft 810. A fixing ring 811 is provided on the outside of the rotating shaft 810, and the side of the fixing ring 811 opposite to the movable platform 807 is bolted to the inner wall of the fixing ring 811. An annular spring 8 is bolted to the inner wall of the fixing ring 811. 13. A flat-toothed ring 812 is engaged with the inner wall of the annular spring 813. The inner wall of the flat-toothed ring 812 is bolted to the outside of the rotating shaft 810. Multiple short rods equidistantly distributed around the annular spring 813 are inserted into the outside of the annular spring 813. The short rods are bolted to the outside of the same limiting ring 814. A movable collar 815 is bolted to the outside of the limiting ring 814. A rectangular opening is provided on the movable collar 815. A guide rod 816 is slidably connected inside the rectangular opening. The guide rod 816 is bolted to the side opposite to the moving platform 807. A narrow groove is provided at the bottom of the moving platform 807. A fixed rod 817 is slidably connected inside the narrow groove. The bottom of the fixing rod 817 is bolted to the upper side of the frame 10. A strip-shaped groove is formed on the outside of the moving stage 807. A straight rack 818 is bolted to the inner wall of the strip-shaped groove. A sliding groove is formed on the inner wall of the narrow groove, and a movable rack 819 is slidably connected to the inner wall of the sliding groove. The outside of the movable rack 819 engages with the outside of the straight rack 818. Two symmetrical elastic springs 820 are bolted to the outside of the moving stage 807. The ends of the elastic springs 820 away from the moving stage 807 are bolted to the outside of the movable rack 819. A groove 821 is formed on the inner wall of the narrow groove on the side away from the movable rack 819. The inner wall of the frame 807 is slidably connected to the fitting piece 822. The fixing rod 817 has a fitting opening on the side away from the linear rack 818. The inner wall of the fitting opening is slidably connected to the outer wall of the fitting piece 822. The inner wall of the groove 821 is bolted to two symmetrical springs 824. The end of the spring 824 near the fitting piece 822 is bolted to the outer wall of the fitting piece 822. The bottom of the moving stage 807 is bolted to the support frame 823. The inner wall of the support frame 823 is slidably connected to the round rod 825. The outer wall of the round rod 825 is bolted to two symmetrical bosses. The side of the bosses opposite to the frame 10 is bolted to the support frame 10.

[0027] Specifically, after the doctor puts on the protective glasses 5, they gently press the fitting piece 822 against the elastic force of the spring 824, placing the moving stage 807 on the fixed rod 817. They then release the fitting piece 822, allowing it to engage with the fixed rod 817. Simultaneously, they place the support frame 823 onto the round rod 825. They then gently push the moving stage 807, causing the movable rack 819 to slide on the linear rack 818 against the elastic force of the spring 820, adjusting the position of the moving stage 807 on the protective glasses 5. After adjustment, the movable rack 819 engages with the linear rack 818, and the moving stage 807 stops moving. They then pull the movable collar 815, causing it to drive the limiting ring 814 to pull the short plate out from the outside of the annular spring 813. Finally, they rotate the fixed frame 803, causing the flat-mouthed toothed ring 812 to overcome the elastic force of the annular spring 813 and drive the rotating shaft 810 to rotate, thus allowing the moving stage to move. The bracket 806 connected to the rotating shaft 810 drives the frame 10 to rotate to a position parallel to the protective glasses 5, pushes the movable collar 815 back, and re-inserts the short plate into the outside of the annular spring 813. The rotating shaft 810 stops rotating, and the ultrasound instrument body 1 is started. When the doctor operates the rod probe 3, the ultrasound instrument body 1 generates an image of the probe 3 and sends it to the main display screen 7 and the signal transmitter 6. The signal transmitter 6 converts the image into a signal and sends it to the signal receiver 804. After receiving the signal, the signal receiver 804 converts it back into an image and sends it to the LBS laser source 805. The LBS laser source 805 scans the image through a laser beam and a high-frequency micromirror to generate an image, which is then irradiated onto the collimating lens 801 and the freeform mirror 802. After image magnification and aberration correction, the doctor can clearly see the ultrasound image of the rod probe 3.

[0028] In specific application scenarios, the head-up display module 8 is mainly used in the head-up display stage of the head-up display process. That is, the head-up display module 8 uses protective glasses 5, glasses frame 10, signal transmitter 6, LBS laser light source 805, and signal receiver 804 to enable the device to directly display ultrasound images in front of the doctor's eyes, improving the doctor's surgical efficiency. Through the rotatable and movable bracket 806 and the moving stage 807, the doctor can choose the observation eye independently, and when it is not necessary to observe the ultrasound image, the glasses frame 10 can be easily flipped, making the operation simpler and reducing the doctor's workload.

[0029] Reference Figure 1 , Figure 7 and Figure 8In a preferred embodiment, an ultrasound probe is used in an interventional ultrasound device as described above. A coupling agent delivery module 9 is provided on the outside of the rod probe 3. The coupling agent delivery module 9 includes an annular tube 901. The inner wall of the annular tube 901 is bolted to the outside of the rod probe 3. Three equally spaced branch pipes 902 are provided at the bottom of a check valve 910. A guide groove 903 is provided on the outside of the rod probe 3. A circular hole is opened on the annular tube 901, and a delivery pipe 904 is bolted to the inner wall of the circular hole. A syringe barrel 905 is inserted into the end of the delivery pipe 904 away from the annular tube 901. A piston head 906 is slidably connected inside the syringe barrel 905. A core rod 907 is provided on the upper side of the piston head 906. An annular airbag 908 is provided outside the core rod 907. An annular plate is bolted to the upper side of the annular airbag 908. The outer side of the annular plate is connected to the inner wall of the syringe barrel 905. The annular plate is located outside the core rod 907 via bolts, and a slot is provided on the annular plate. An air guide tube 909 is installed in the slot. One end of the air guide tube 909 is connected to the annular airbag 908, and the other end is bolted to the pressing airbag 913. A check valve 910 is installed outside the air guide tube 909. The rod probe 3 is bolted to the outside of an annular component 911. The annular component 911 is bolted to the outside of a receiving frame 912. The inner wall of the receiving frame 912 is bolted to the outside of the pressing airbag 913. A pressing head 914 is bolted to the upper side of the pressing airbag 913. The outside of the pressing head 914 is slidably connected to the inner wall of the receiving frame 912. A second spring 915 is bolted to the inner wall of the receiving frame 912. The end of the second spring 915 away from the receiving frame 912 is bolted to a transmission plate 916. The outside of the transmission plate 916 is slidably connected to the inner wall of the receiving frame 912.

[0030] Specifically, when the doctor operates the rod probe 3, the bottom of the rod probe 3 is placed at the puncture position, the puncture needle is placed in the guide groove 903, and the pressing head 914 is pressed lightly and continuously. The pressing head 914 compresses the pressing airbag 913, so that the air in the pressing airbag 913 is continuously introduced into the annular airbag 908 through the air guide tube 909 and the check valve 910, causing the annular airbag 908 to gradually expand downward, thereby driving the core rod 907 and the piston head 906 to press down, and the coupling agent in the syringe barrel 905 is delivered to the check valve 910 through the delivery tube 904. Finally, the branch tube 902 discharges the coupling agent, so that the coupling agent is applied to the detection position. The puncture needle is gently pushed to start the puncture.

[0031] In specific application scenarios, the coupling agent delivery module 9 is mainly used in the coupling agent delivery stage of the coupling agent delivery process. That is, the coupling agent delivery module 9 uses the press-type airbag 913, the ring airbag 908 and the check valve 910 to allow the doctor to choose the timing of coupling agent release, thereby avoiding the uniform application of coupling agent, reducing coupling agent waste, and avoiding unclear ultrasound images caused by uneven coupling agent application. The guide groove 903 can limit the puncture needle. By fixing the puncture angle, the doctor can always observe the puncture situation through the rod probe 3 during the puncture operation. The rod probe 3 makes the doctor's control more flexible. The rod probe 3 reduces the field of view of the image, thereby increasing the doctor's focus on the puncture site when performing radial and femoral artery punctures and improving the surgical effect.

[0032] Working principle: After the doctor puts on the protective glasses 5, the doctor gently presses the locking plate 822 against the elastic force of the spring 824, placing the moving stage 807 on the fixed rod 817. The locking plate 822 is then released, allowing it to engage with the fixed rod 817. Simultaneously, the support frame 823 is fitted onto the round rod 825. The moving stage 807 is gently pushed, causing the movable rack 819 to slide on the linear rack 818 against the elastic force of the spring 820, adjusting the position of the moving stage 807 on the protective glasses 5. After adjustment, the movable rack 819 engages with the linear rack 818, and the moving stage 807 stops moving. Pulling the movable sleeve... Ring 815 causes the movable collar 815 to drive the limiting ring 814 to pull the short plate out from the outside of the annular spring 813. Rotating the fixing frame 803 causes the flat toothed ring 812 to overcome the elastic force of the annular spring 813 and drive the rotating shaft 810 to rotate. This causes the bracket 806 connected to the rotating shaft 810 to rotate the eyeglass frame 10 to a position parallel to the protective glasses 5. Pushing the movable collar 815 back in allows the short plate to be reinserted into the outside of the annular spring 813. The rotating shaft 810 stops rotating. The ultrasound machine body 1 is started. When the doctor operates the rod probe 3, the bottom of the rod probe 3 is placed at the puncture position. Insert the puncture needle into the guide groove 903, and continuously press the pressing head 914 gently. The pressing head 914 compresses the pressing airbag 913, causing air from the pressing airbag 913 to continuously enter the annular airbag 908 through the air delivery tube 909 and check valve 910. This causes the annular airbag 908 to gradually expand downwards, thereby driving the core rod 907 and piston head 906 to press down. The coupling agent in the syringe barrel 905 is delivered to the check valve 910 through the delivery tube 904, and finally the branch tube 902 discharges the coupling agent, allowing the coupling agent to be applied to the detection position. Gently push the puncture needle to begin the puncture. The ultrasound instrument body 1 will then... The probe 3 generates an image based on the detection and sends it to the main display screen 7 and the signal transmitter 6. The signal transmitter 6 converts the image into a signal and sends it to the signal receiver 804. The signal receiver 804 receives the signal and converts it back into an image, which is then sent to the LBS laser source 805. The LBS laser source 805 scans the image through a laser beam and a high-frequency micromirror to generate an image, which is then irradiated onto the collimating lens 801 and the freeform mirror 802. After image magnification and aberration correction, the doctor can clearly see the ultrasound image of the rod probe 3. After the puncture is completed, the puncture needle is withdrawn from the patient and the guide groove 903.
