Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an ultrasonic aspiration surgical device. Background Technology

[0002] With the rapid development of minimally invasive surgical techniques, ultrasonic aspiration surgical devices, with their integrated advantages of precise ultrasonic ablation, tissue dissection, and intraoperative negative pressure suction of waste materials, are widely used in various delicate surgical scenarios such as general surgery, neurosurgery, plastic surgery, and tumor resection. Ultrasonic surgical devices primarily utilize piezoelectric transducers to convert electrical energy into high-frequency ultrasonic energy. Through high-frequency vibration of the blade, they achieve the cutting, pulverization, and ablation of diseased tissue. Simultaneously, the negative pressure suction structure promptly removes intraoperative tissue debris, waste fluid, and exudate, effectively exposing the surgical field, reducing surgical trauma, and improving the precision of the surgery. It is an indispensable core medical device in modern minimally invasive surgery. Currently, the overall market demand for ultrasonic aspiration surgical devices continues to rise, and minimally invasiveness, intelligence, and precision have become the core development trends for equipment iteration and upgrading in the industry.

[0003] However, current traditional ultrasonic aspiration surgical equipment still suffers from numerous technical defects and shortcomings in actual clinical use, severely restricting surgical precision and safety. Existing equipment uses a single, fixed ultrasonic energy transmission path, unable to flexibly switch between ultrasonic conduction and negative pressure transmission channel structures according to different surgical sites, soft and hard tissues, and varying surgical precision requirements, resulting in poor adaptability. Conventional equipment can only operate with fixed parameters, failing to match corresponding transmission modes for different conditions such as delicate minimally invasive surgeries and large-area tissue dissection surgeries. This easily leads to uneven ultrasonic energy distribution and unstable adsorption effects, potentially causing minor damage to normal tissue or incomplete removal of diseased tissue.

The end of the data interface 8 away from the piezoelectric ceramic transducer 4 is inserted into the inner side of the ultrasonic guide groove 1 32. Four transmission path holes 35 are opened inside the hand-rotating block 7. The hand-rotating block 7 is rotatably installed on the outside of the protective connecting tube 29.Four identification plates 18 are fixedly installed on the outside of the hand-operated block 7, and the positions of the four identification plates 18 correspond to the positions of the four transmission path holes 35. Magnet rings 40 are fixedly installed at both ends of the hand-operated block 7. The magnet rings 40 are respectively rotatably attached to the outside of the ends of the protective shell 2 6 and the protective shell 1 5. The four transmission path holes 35 are transmission path hole one, transmission path hole two, transmission path hole three, and transmission path hole four. The internal hole shapes of transmission path hole one, transmission path hole two, transmission path hole three, and transmission path hole four are respectively straight cylindrical hole, frustum conical hole, elliptical flat hole, and stepped hole. Transmission path hole one has the largest amplitude and the strongest ultrasound. For removing hard lesions, the second transmission path hole has a medium to strong ultrasound intensity, used for routine resection of solid organs, dissection of the main tumor body, and cleaning of superficial tissues. The third transmission path hole has a medium ultrasound intensity, used for fine dissection. The fourth transmission path hole has the smallest amplitude and the weakest ultrasound intensity, used for delicate operations near nerves and blood vessels. The bottom of the support and fixing platform 1 has a threaded mounting groove 23, inside which is a threaded mounting tube 31. A negative pressure collection bottle 10 is fixedly installed at the bottom of the threaded mounting tube 31. The bottom of the ultrasound control box 2 is fixedly connected to a discharge tube 24, which is located inside the threaded mounting groove 23 and connected to the suction interface 25.

[0026] The working principle of the above technical solution is as follows: the ultrasonic control box 2 mounted on the support platform 1 is connected to the mains power supply through the power interface 19 on the back. Pressing the switch button 9 on the front of the ultrasonic control box 2 completes the power-on operation of the whole machine. The touch screen display 3 lights up simultaneously and starts the system self-test. After the equipment has no abnormalities, it enters the standby working state. Before surgery, the negative pressure suction tube 21 and the transmission wire 22 are inserted into the suction interface 25 and the transmission interface 26 on one side of the ultrasonic control box 2, respectively, to complete the standardized connection and assembly of the equipment's air and electrical circuits. The end of the transmission wire 22 is directly electrically connected to the piezoelectric ceramic transducer 4, which is responsible for stably transmitting control electrical signals to the transducer. The negative pressure suction tube 21 is precisely connected to the negative pressure suction tube 36 inside the handheld component. A smart valve is installed at the connection point between the two to precisely control the opening and closing of the negative pressure air circuit and the airflow. At the same time, a dedicated control button is installed on the outside of the piezoelectric ceramic transducer 4, which can independently control the smart valve at the connection point to realize the manual start and stop adjustment of the negative pressure system according to the size of the surgical wound, the tissue type, and the precision requirements of the surgery. The operator can manually rotate the hand-operated rotating block 7. The hand-operated rotating block 7 has four different aperture structures of transmission path holes 35 evenly arranged inside, namely straight cylindrical holes, frustum-shaped holes, elliptical flat holes and stepped holes, which can be adapted to ultrasonic transmission and negative pressure adsorption operations of different intensities. The identification plate 18 fixed on the outside of the hand-operated rotating block 7 corresponds one-to-one with the transmission path holes 35, which makes it easy for the operator to quickly identify and accurately switch the operation mode. At the same time, the magnetic rings 40 assembled at both ends of the hand-operated rotating block 7 can be magnetically attracted to the ends of the protective shell 1 5 and the protective shell 2 6 to achieve precise positioning and fixation after rotation, effectively preventing the rotating block from shifting or the path from being misaligned during operation, and ensuring the stability and accuracy of ultrasonic energy and negative pressure airflow transmission. The operator sets parameters such as ultrasonic vibration frequency and operating power as needed through the touch screen display 3. The electrical signal is accurately transmitted to the piezoelectric ceramic transducer 4 through the transmission wire 22. After receiving the electrical signal, the piezoelectric ceramic transducer 4 completes the energy conversion, converting electrical energy into high-frequency ultrasonic energy, and preferentially transmits the ultrasonic waves to the front ultrasonic catheter 28. The ultrasonic waves are stably transmitted along the ultrasonic catheter 28, passing through the ultrasonic guide groove 32 inside the fixed plate 1 34 and the pre-aligned transmission path hole 35 inside the hand rotating block 7, and then being discharged through the corresponding ultrasonic guide groove 37 inside the fixed plate 2 38. The discharged high-frequency ultrasonic waves directly impact the surface of the high-frequency vibration guide plate 42, driving the high-frequency vibration guide plate 42 to vibrate at high speed, and simultaneously driving the high-frequency vibration catheter 30, the internal moving tube 16 and the end scalpel 17 to vibrate at high frequency. The high-frequency vibration enables precise cutting, peeling and ablation of human diseased tissue. During the operation, the hand rotating block 7 can be rotated at any time to adjust the type of the transmission path hole 35 between the ultrasonic guide groove 1 32 and the ultrasonic guide groove 2 37 to adapt to different surgical conditions. During ultrasound surgery, the operator can press the control button on the outside of the piezoelectric ceramic transducer 4 to activate the intelligent valve at the connection between the negative pressure suction tube 1 21 and the negative pressure suction tube 2 36, opening up the complete negative pressure adsorption path. The negative pressure suction generated by the device is transmitted along the pipeline to the suction hole 27 at the top of the scalpel 17, which can adsorb surgical waste such as tissue debris, waste fluid, and exudate generated during the operation in real time. The waste passes through the suction hole 27, the moving tube 16, the negative pressure suction tube 2 36, and the negative pressure suction tube 1 21 in sequence, and is introduced into the discharge tube 24 through the suction interface 25. Finally, it is uniformly and sealed and collected in the negative pressure collection bottle 10 through the threaded installation tube 31 inside the threaded installation groove 23. At the same time, the intelligent valve can be flexibly started and stopped and the negative pressure can be adjusted according to the rhythm of the operation to avoid damage to normal tissue caused by continuous negative pressure adsorption, thus improving the safety of the operation. The entire surgical equipment is equipped with a movable support structure. The support column 14 at the bottom of the support platform 1 plays a core supporting role, ensuring the overall stability of the equipment during operation. The universal ball casters 13 at the four corners of the bottom of the support base 12 can realize the smooth movement and precise positioning of the equipment in any direction, which makes it convenient for medical staff to flexibly adjust the placement of the equipment according to the surgical position and surgical area. At the same time, a waste disposal box 15 is fixedly installed on the side of the support column 14, which can temporarily store surgical gauze, waste consumables and other auxiliary items, keep the operating table clean, effectively improve the convenience and standardization of surgical operations, and adapt to the operational needs of various surgical scenarios.

[0027] In another implementation scheme, such as Figures 1-7 As shown, an outer protective sleeve 11 is installed on the outside of the negative pressure suction tube 21 and the transmission wire 22, and a heat dissipation window 20 is installed on the back of the ultrasonic control box 2.

[0028] The outer protective sleeve 11, which is attached to the outside of the negative pressure suction tube 21 and the transmission wire 22, can provide all-round protection for the pipeline, preventing the pipeline from bending, abrasion, or falling off, and ensuring the stability of circuit transmission and air adsorption. The heat dissipation window 20 on the back is constantly open for heat dissipation, which can quickly dissipate the heat generated by the internal circuit and control module of the ultrasonic control box 2, avoiding problems such as overheating, program lag, or hardware damage during long-term operation of the equipment, effectively ensuring the stability and continuity of the whole machine operation, and providing a reliable equipment operation foundation for subsequent ultrasonic surgery and negative pressure adsorption operations.

[0029] In another implementation scheme, such as Figures 1-7 As shown, the mobile support assembly includes a support pole 14, a support base 12 is fixedly installed at the bottom of the support pole 14, and omnidirectional ball wheels 13 are installed at the four corners of the bottom of the support base 12. A garbage disposal box 15 is fixedly installed on one side of the support pole 14.

[0030] The entire surgical equipment is equipped with a movable support structure. The support column 14 at the bottom of the support platform 1 plays a core supporting role, ensuring the overall stability of the equipment during operation. The universal ball casters 13 at the four corners of the bottom of the support base 12 can realize the smooth movement and precise positioning of the equipment in any direction, which makes it convenient for medical staff to flexibly adjust the placement of the equipment according to the surgical position and surgical area. At the same time, a waste disposal box 15 is fixedly installed on the side of the support column 14, which can temporarily store surgical gauze, waste consumables and other auxiliary items, keep the operating table clean, effectively improve the convenience and standardization of surgical operations, and adapt to the operational needs of various surgical scenarios.

[0031] Working principle: Connect to the mains power supply through the power interface 19 on the back of the ultrasonic control box 2 mounted on the support platform 1, press the switch button 9 on the front of the ultrasonic control box 2 to complete the whole machine power-on operation, the touch screen display 3 lights up simultaneously and starts the system self-test, and enters the standby working state after the equipment has no abnormalities. During equipment operation, the back heat dissipation window 20 is continuously open for heat dissipation, which can quickly dissipate the heat generated by the internal circuit and control module of the ultrasonic control box 2, and avoid overheating, program lag or hardware damage during long-term operation of the equipment. This effectively ensures the stability and continuity of the whole machine operation, and provides a reliable equipment operation foundation for subsequent ultrasonic surgery and negative pressure adsorption operations. Before the operation, the negative pressure suction tube 21 and the transmission wire 22 are respectively inserted into the suction interface 25 and the transmission interface 26 on one side of the ultrasonic control box 2 to complete the standardized connection and assembly of the equipment's air circuit and circuit. The end of the transmission wire 22 is directly electrically connected to the piezoelectric ceramic transducer 4, which is responsible for stably transmitting control electrical signals to the transducer. Negative pressure suction tube 21 is precisely connected to negative pressure suction tube 36 inside the handheld component. A smart valve is installed at the connection point between the two to precisely control the opening and closing of the negative pressure airway and the airflow. At the same time, a dedicated control button is installed on the outside of the piezoelectric ceramic transducer 4, which can independently control the smart valve at the connection point to realize the manual start and stop control of the negative pressure system. The outer protective sleeve 11 sleeved on the outside of negative pressure suction tube 21 and transmission wire 22 can provide all-round protection for the tubing to prevent bending, wear and detachment, and ensure the stability of circuit transmission and air adsorption. It can be adjusted according to the size of the surgical wound, tissue type and surgical precision requirements. The operator can manually rotate the hand-operated rotating block 7.
