Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
Referring to fig. 1, fig. 2 and fig. 3, an embodiment of the present invention includes:
example 1
As shown in fig. 1, an embodiment of the present invention provides an ultrasonic osteotome handle with a force control device, including an ultrasonic osteotome head 1, an ultrasonic osteotome handle 2, an ultrasonic osteotome handle sliding sleeve 3 and a compression spring 41. The specific settings are as follows:
The compression spring 41 is fixed between the tail end of the ultrasonic osteotome handle 2 and the tail end of the ultrasonic osteotome handle sliding sleeve 3, and the compression spring 41 can be a single spring or can be symmetrically designed for paired springs. After installation, the compression spring 41 is in a semi-compression state, at the moment, the front end of the ultrasonic osteotome handle 2 is in contact with the front end of the ultrasonic osteotome handle sliding sleeve 3, and the elasticity of the compression spring 41 is a cutting pressure low value when the maximum cutting efficiency interval exists. When the head end of the ultrasonic osteotome head 1 is pressed and the pressure is lower than the elastic force in the initial compression state, the ultrasonic osteotome handle 2 can not slide in the ultrasonic osteotome handle sliding sleeve 3; when the pressure is increased to be higher than the elastic force in the initial compression state, the ultrasonic osteotome handle 2 slides in the ultrasonic osteotome handle sliding sleeve 3 (the surgeon can sense the low value of the cutting pressure in the maximum cutting efficiency interval), the compression spring 41 is compressed along with the elastic force, the elastic force is gradually increased, the cutting pressure at the head end of the ultrasonic osteotome head 1 is increased along with the elastic force, when the compression spring 41 is compressed to the bottom, the elastic force is the high value of the cutting pressure in the maximum cutting efficiency interval, the compression spring 41 is not retracted when the pressure is increased, no sliding exists between the ultrasonic osteotome handle 2 and the ultrasonic osteotome handle sliding sleeve 3 (the surgeon can sense the high value of the cutting pressure in the maximum cutting efficiency interval), and the operation pressure does not need to be increased. Pressure cutting bone near the midpoint of the elastic zone is essentially the highest surgical cutting efficiency. The efficiency is needed in the early bone cutting stage, but the safety is especially needed when the aim is to be achieved, when the force control device is not closed, the front thrust generated by the restoration of the compressed force control device after the bone is cut through without resistance can lead the ultrasonic bone knife head 1 to be displaced forwards at the operation position to possibly damage the tissues to be protected. Therefore, when the safety of the operation needs to be ensured, the low value of the cutting pressure and the operation below the low value can be returned when the ultrasonic osteotome handle 2 and the ultrasonic osteotome handle sliding sleeve 3 do not slide in the maximum cutting efficiency interval, but the operation efficiency is reduced; the ultrasonic osteotome handle 2 and the ultrasonic osteotome handle sliding sleeve 3 are also provided with a fastening screw 6 therebetween, and the fastening screw 6 can be screwed to fix the ultrasonic osteotome handle 2 and the ultrasonic osteotome handle sliding sleeve 3 so as to prevent the ultrasonic osteotome handle sliding sleeve from sliding and prevent the cutting pressure from being transmitted to the compression spring 41, so that the ultrasonic osteotome head 1 cannot move to damage tissues which are not damaged due to the rebound of the compression spring 41 when the pressure at the front end of the osteotomy head is suddenly reduced.
