Embodiment approach 1

[0035] Such as figure 1 As shown, this embodiment discloses a minimally invasive ultrasonic knife head 1, which includes a knife bar 11 and a head end 12, the head end 12 is located at the front end of the knife bar 11, and the head end 12 is bent to the side at a certain angle. The bottom surface 121 of the curved portion is a square arc surface, and knurled teeth are provided on the upper and lower slopes of the transverse surface 122 of the curved portion.

[0036] During the assembly process, since the curved head end cannot pass through the channel of the foramina, in order to enable the minimally invasive ultrasonic knife head 1 to work with the foramina, as figure 2 As shown, the knife rod 11 of the minimally invasive ultrasonic knife head is divided into two parts, that is, the front half connected to the head end 12 and the second half connected to the ultrasonic handle. These two parts are connected by threads, and the threads can tightly connect the front half and...

Embodiment approach 2

[0041] Figure 6 It is the minimally invasive ultrasonic cutter head 2 according to the second embodiment of the present invention. The cutter head 2 includes a cutter bar 21 and a head end 22. The head end 22 is located at the front end of the cutter bar 21. The head end 22 is bent to the side at a certain angle. The head end 22 is rake-shaped with helical teeth on the transverse face 222 of the curved portion.

[0042]Similar to Embodiment 1, in order to facilitate assembly, the knife bar 21 is also divided into two parts, namely the front half connected to the head end 22 and the second half connected to the handle, and the two parts are connected by threads. The cutter bar 21 can be a hollow structure, and water can be poured directly at the head end; or only a part can be a hollow structure, and water can be discharged through a side hole in the middle of the cutter bar.

[0043] The minimally invasive ultrasonic cutter head 2 can also be used in a minimally invasive ult...

Embodiment approach 3

[0045] Figure 7 It is the minimally invasive ultrasonic cutter head 3 according to the third embodiment of the present invention. The cutter head 3 includes a cutter bar 31 and a head end 32. The head end 32 is located at the front end of the cutter bar 31. The head end 32 is bent to the side at a certain angle. The head end 32 is spoon-shaped, with knurled teeth on the top surface 324 of the curved portion. Further, helical teeth can be provided on the lateral surface 322 and the side surface 323 of the curved portion.

[0046] Similar to Embodiment 1, in order to facilitate assembly, the tool bar 31 is also divided into two parts, namely the front half connected to the head end 32 and the second half connected to the handle, and the two parts are connected by threads. The cutter bar 31 can be a hollow structure, and water can be poured directly at the head end; or only a part can be a hollow structure, and water can be discharged through a side hole in the middle of the cu...

Abstract

The invention relates to a minimally invasive ultrasonic scalpel head and a minimally invasive ultrasonic bone power system, the minimally invasive ultrasonic scalpel head comprises a scalpel bar anda head end, the head end is located at the front end of the scalpel bar, the head end is bent laterally at a certain angle, and knurled teeth or helical teeth are provided on a curved portion. By bending the head end, the bone tissue around a transforaminal endoscope can be removed, so that an operator has more operating space under a limited endoscope channel, and the bone removal efficiency is improved. The knurling teeth or helical teeth are provided at the curved portion, which can better polish or cut the bone tissue around the transforaminal endoscope.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a minimally invasive ultrasonic cutter head and a minimally invasive ultrasonic bone dynamic system. Background technique [0002] With the development of modern medical technology, minimally invasive surgery under the transforaminal microscope has been widely used in clinical orthopedic surgery. Existing power tools under the intervertebral foramen mirror are mainly high-speed grinding drills, which grind away bone tissue through the high-speed rotation of the grinding drill head. Due to the rotating working method, the drill is easy to roll and scrape soft tissue during operation, resulting in a wire drawing effect, and prone to blood blindness, resulting in unclear vision of medical personnel, which in turn leads to medical accidents. [0003] Ultrasonic bone dynamic system is a power tool that uses ultrasonic energy for surgery. It has outstanding features such as fi...
