Show.
Alternatively, after described selection virtual operation scene, methods described also includes：
The scene adjust instruction of receiving user's input, according to described scene adjust instruction to described selection virtual operation scene
It is adjusted.
Alternatively, described stage property is included using data：Using position, use degree and use time.
The invention has the advantages that：
The present invention passes through sham operated scene, and intern can be allowed to undergo operation process, turn avoid practice doctor
When life carries out surgical error, the impact that patient is caused.
Brief description
Fig. 1 is a kind of flow process of Minimally Invasive Surgery analogy method based on virtual reality technology provided in an embodiment of the present invention
Figure.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Fig. 1 is a kind of flow process of Minimally Invasive Surgery analogy method based on virtual reality technology provided in an embodiment of the present invention
Figure；With reference to Fig. 1, methods described includes step S101～S105：
S101：Choose virtual operation scene, described virtual operation scene includes：Background environment, operation stage property and patient；
It should be noted that the executive agent of the method for the present embodiment is controller that is to say, that can be to virtual reality
The device that equipment is controlled, is alternatively the equipment such as host computer certainly, and the present embodiment is not any limitation as to this.
It will be appreciated that the method for the present embodiment can pre-set different virtual operation scenes, such as：Background environment is
Branch Clinic, large hospital etc., described patient is old man, child or middle age etc..
The motility of virtual operation scene in implementing, is selected for increasing user, in the present embodiment, can receive user
The scene adjust instruction of input, is adjusted to described selection virtual operation scene according to described scene adjust instruction.
S102：By corresponding for the user predeterminated position to described virtual operation scene；
S103：Image to be presented is determined according to described predeterminated position and virtual operation scene, and to described image to be presented
It is shown；
It will be appreciated that user can be showed by virtual reality head mounted display to described image to be presented, certainly,
Also can show that the equipment of image is shown by other, the present embodiment is not any limitation as to this.
S104：Using instruction, the operation stage property obtaining user, using instruction, determines that user is made according to described operation stage property
Operation stage property, and record stage property and use data；
It will be appreciated that for ease of the instruction obtaining user, in the present embodiment, use can be obtained by virtual reality handle
The instruction at family, certainly, also can adopt other equipment, for example：Virtual reality glove also obtains the instruction of user, present embodiment pair
This is not any limitation as.
In implementing, operation stage property generally includes：The stage properties such as scalpel, suture utensil, disinfectant solution, described stage property makes
