Furthermore, actual operating personnel can rotate the calibration frame to realize accurate positioning according to actual needs, and due to the rotatable structure, the actual operation is convenient.
In a second aspect of the embodiments of the present disclosure, there is provided a method of use applied to the navigation system for hip replacement surgery as described above, the method comprising:
placing the acetabular cup prosthesis of the front-end beating component in an acetabular fossa of the human body;
rotating the rotating assembly to drive the calibration frame assembly to rotate;
determining second position information of the front end striking assembly based on the first position information of the rotated calibration frame assembly;
press-fitting the acetabular cup prosthesis upon determining that the second positional information satisfies a preset positional condition.
It should be noted that, since the position of the front end striking assembly is fixed relative to the calibration frame assembly, the actual position coordinate information (i.e. the second position information mentioned above) of the front end striking assembly can be obtained by determining the position coordinate information of the reflected light ball on the calibration frame assembly. Alternatively, the actual position coordinate information of the front end striking assembly may be determined by the actual position coordinate information of the acetabular cup prosthesis of which the front end striking assembly is determined. After the actual position coordinate information of the front-end striking assembly is determined, if the difference value between the actual position coordinate information and the theoretical position coordinate information is determined to be smaller than or equal to a first preset difference value (namely the second position information is determined to meet the preset position condition), the acetabular cup prosthesis can be pressed and assembled based on the determined actual position coordinate information, so that the acetabular cup prosthesis is placed in an acetabular socket of a human body. If the difference between the actual position coordinate information and the theoretical position coordinate information is larger than the first preset difference (namely the second position information is determined not to meet the preset position condition), the position of the front end striking assembly is adjusted until the difference between the actual position coordinate information and the theoretical position coordinate information of the front end striking assembly is smaller than or equal to the first preset difference.
It can be understood that, the advantageous effects of the embodiments of the method of the present disclosure can be referred to the advantageous effects of the embodiments of the navigation and positioning system for hip replacement surgery, and the embodiments of the present disclosure are not described herein again.
In a third aspect of the embodiments of the present disclosure,
providing a surgical robot system, comprising an optical navigator 5, an optical navigator display 6 and the hip replacement surgery navigation and positioning system as described in any one of the preceding claims, wherein the optical navigator 5 is configured to position spatial position information of the calibration frame assembly and transmit the spatial position information to the optical navigator display 6 for displaying;
press-fitting a target object through the front-end impact assembly based on the spatial information.
Illustratively, the anterior striking assembly includes a central shaft and an acetabular cup prosthesis, one end of the central shaft threadably coupled to the acetabular cup prosthesis. In the surgical robot system of the embodiment of the disclosure, the acetabular cup prosthesis of the front-end striking assembly is arranged in the acetabular socket of the acetabulum 7, and since the position information of the acetabular cup prosthesis relative to the calibration frame assembly can be obtained through coordinate conversion, the position information of the acetabular cup prosthesis can be actually obtained by obtaining the position information of the calibration frame assembly.
Through the spatial position information of the optical navigator positioning calibration frame assembly, the spatial information is transmitted to the optical navigator display to be displayed, and actual operators can accurately acquire corresponding position information according to actual needs, so that the optical navigator positioning calibration frame assembly is convenient for actual operation.
It can be understood that, in addition to the beneficial effects of the embodiment of the navigation and positioning system for hip replacement surgery, the embodiment of the surgical robot system of the present disclosure may obtain the position information of the striking head by obtaining the position information of the calibration frame assembly, wherein the position information of the striking head of the front-end striking assembly relative to the calibration frame assembly is obtained by coordinate transformation.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present disclosure, and not for limiting the same; while the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present disclosure.
