Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to a multi-directional ultrasonic surgical knife system. Background Art

[0002] Ultrasonic scalpel uses high-intensity focused ultrasound technology to convert electrical energy into vibration mechanical energy through a transducer. Through high-frequency ultrasonic vibration, the water in the contacted tissue cells is vaporized and the protein hydrogen bonds are broken, thereby completely destroying the bone tissue that needs to be cut during the operation. Since this high-intensity focused ultrasound only has a destructive effect on bone tissue of a specific hardness, it will not only not damage blood vessels and nerve tissues, but also stop bleeding at the surgical wound, further reducing the incision of minimally invasive surgery, greatly improving the accuracy, reliability and safety of the operation.

[0003] After extensive searches by our team, we learned that the existing ultrasonic surgical knives mainly include those with publication numbers JP2014533132A, KR101331155B1 and CN101790358B. Among them, the ultrasonic surgical knife structure disclosed by publication number CN104173093B is particularly representative. The ultrasonic knife head is integrated with a torque limiting device, which also has the characteristic of not being easily lost. The torque limiting device in the present invention is composed of a rotating device and a force transmission device. The force application surface of the rotating device and the force receiving surface of the force transmission device are pressed together by a pushing mechanism, and the force application surface and the force receiving surface can be helical teeth arranged along the circumferential direction and meshed with each other. The torque is transmitted by the force between the force application surface and the force receiving surface, and the magnitude of the friction force depends on the pressure of the pushing mechanism. Therefore, as long as the pushing force is reasonably set, the set torque can be transmitted. When the torque is greater than the set value, the mutually meshing helical teeth will overcome the pushing force and friction of the pushing mechanism and slip, thereby limiting the transmission of torque and playing a protective role. The operator only needs to rotate the rotating device to lock the external driving handle, remove the driving handle, and rotate the angle of the blade. The operation is simple and convenient. This structure improves the stability and convenience of the blade, but the blade angle and blade direction of the ultrasonic knife of this structure are fixed. The fixed angle of the control handle also limits the user's ability to rotate and adjust the angle of the scalpel. In addition, in order to improve the control of the scalpel, the operator generally uses a straight grip to perform surgery. This gesture is often easily blocked by the scalpel when the medical staff is standing next to the patient and operating. Summary of the invention

[0058] The application method of the ultrasonic surgical knife system includes:

[0059] S1. Preparation: After the patient is anesthetized on the operating table, an incision is made at the location corresponding to the lesion;

[0060] S2, ultrasonic cutting, when it is necessary to use an ultrasonic scalpel to remove hard tissue, the scalpel handle is held with an inverted grip so that the thumb can touch the second control button 223, and the index finger or middle finger can touch the first control button 222, and then the first control button 222 is pressed to start the operation of the sound wave generating device and the transducer mechanism 23, and the working blade 32 is driven to vibrate at a high frequency through the transmission mechanism 31, and then the doctor can use the ultrasonic scalpel to cut the hard tissue (such as spinal bones) that needs to be removed;

[0061] S3, rotation adjustment and rotation cutting, when rotation cutting is required, by pressing the second control button 223, the first drive motor 331 starts to drive the driven gear ring 333 to rotate around the center of the gear ring, and at the same time drives the eccentrically arranged sleeve rod 335 to rotate, and the sleeve rod 335 drives the internal amplitude rod 315 to rotate synchronously, which can drive the working cutter head 32 to perform circumferential rotation and vibration cutting, and then intuitively understand the moving path and area of ​​cutting according to the light emitted by the indication module 4, so as to align the working cutter head 32 with the hard tissue so as to make the working cutter head 32 perform directional cutting according to the marked cutting area;

[0062] S4. During the operation of the ultrasonic surgical knife, the cooling spray module 5 continuously supplies water to the water flow channel of the sleeve rod 335. The clean water takes away the heat after passing through the sleeve rod 335 for heat dissipation. Then, the sleeve rod 335 tilts toward the water outlet provided on the working blade head 32 and sprays it on the working blade head 32, thereby cooling and cleaning the working blade head 32. Then, the second catheter is extended into the effluent surface to absorb the excess water and scraps.

[0063] The system can receive ultrasound waves and then generate high-frequency vibrations by setting a cutting module 3 to quickly cut hard tissues. At the same time, the ultrasonic scalpel can be operated with a reverse grip, thereby improving the inertial force and stability of the user's arm during operation, while also improving the visible area during operation and reducing the interference of the scalpel to the main surgeon. Then, by setting a rotating mechanism 33 and a transmission mechanism 31, the scalpel can be driven to rotate eccentrically smoothly and stably, and the designated area can be cut open under continuous rotation. At the same time, temporary rotation can also be achieved to quickly adjust the angle of the working blade 32. Then, by setting an indication module 4, the moving path of the scalpel can be clearly grasped to avoid accidental injuries. By setting a cooling spray module 5, the blade head can be cleaned and cooled while reducing the heat of the blade head and the sleeve rod 335 to provide heat dissipation. At the same time, the debris cut out of the human body can be quickly cleaned and absorbed by the absorption device to avoid residual hard objects from scratching other tissues.
