FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 shows the structure of such a pre-operative ophthalmic surgery simulation VR system, and several embodiments are listed below with reference to the figures.
Example 1:
the ophthalmic surgery preoperative simulation VR system comprises VR glasses, wherein the VR glasses comprise a frame body 1, a display screen 2 arranged on the frame body 1, a control system and a voice playing system; an eyelid retractor 3 is also arranged in front of the display screen 2 through the frame body 1.
VR glasses body is prior art, and it is from taking display screen 2, control system, pronunciation play system, but aim at patient broadcast science popularization video, can let the patient experience the operation process with first visual angle to can send the doctor's instruction in the art to the patient, let the patient know how to cooperate in advance. On this basis, set up the eye speculum 3 through framework 1, the eye speculum 3 is located the position that the patient wore the back eyes, is located display screen 2 promptly. The eyelid retractor 3 may be of various types, such as a wire eyelid retractor, a plate eyelid retractor, an adjustable sheet eyelid retractor, etc., and is not limited to this type, and is intended to allow a patient to feel and adapt to the feeling of the eyelid being stretched during surgery, and to eliminate discomfort of the patient.
Example 2:
based on the embodiment 1, it is further defined that the VR glasses further include an eyeball tracker. The eyeball tracking technology is a scientific application technology, firstly, the tracking is carried out according to the characteristic changes of the eyeball and the periphery of the eyeball, secondly, the tracking is carried out according to the angle change of the iris, and thirdly, the characteristics are extracted by actively projecting light beams such as infrared rays and the like to the iris. Different eyeball trackers have different costs and different required working distances, and can be selected according to requirements. When in operation, the patient needs to rotate the eyeball or tightly stare at a certain point to keep still, the patient can be required to stare at the certain point by utilizing the display screen 2 of the invention, the eyeball tracker monitors the corresponding action of the eyeball of the patient, and meanwhile, the correction can be prompted by the voice playing system after the comparison by the control system.
Example 3:
on the basis of the embodiment 1, it is further defined that the frame body 1 is further embedded with a spray head 4 facing towards human eyes, and the spray head 4 is externally connected with a liquid source. The simulation liquid can be sprayed to the eyeball of the patient through the spray head 4, so that the patient can feel the feeling when the anesthetic liquid is sprayed in the operation.
Example 4:
in addition to the above embodiment 3, it is further defined that the frame body 1 is replaceably adhered with absorbent cotton 5. Because the operation needs the patient to lie down, the patient also needs to lie down when the invention is used, the water absorption cotton 5 on the frame body 1 can well absorb the simulation liquid, and the water absorption cotton 5 can be replaced.
Example 5:
in addition to the embodiment 1, it is further limited that the single eyelid retractor 3 includes an opening and closing frame 31 and an eyelid opening hook 32 disposed at an end of the opening and closing frame 31, one end of the eyelid opening hook 32 is connected to the opening and closing frame 31, the other end is connected to the auxiliary frame 6, and the auxiliary frame 6 is connected to the frame 1 through the elastic member 7. The opening and closing bracket 31 is used for controlling the closing of the eyelid opening hook 32, and since the eyelid opener 3 is arranged on the VR glasses in the present invention, the eyelid opener 3 is fixed to a certain extent, and it is inconvenient to operate the eyelid opener 3 in case that the VR glasses are small in size. And auxiliary frame 6 is connected through elastic component 7 with framework 1, and is articulated between auxiliary frame 6 and the elastic component 7, and elastic component 7 can select high-elastic rubber post, spring post etc. for eyelid retractor 3 is floatable, and when the patient was worn, oppressed eyelid retractor 3 made its laminating self eye, made it strut again, and adaptability is stronger still improves the travelling comfort.
Example 6:
in addition to the above embodiment 1, the blood pressure monitor device further includes an arterial blood pressure monitor connected to the housing 1. Some patients are too tense, cannot be effectively matched with an operating doctor for treatment in the operation, have trembling eyeballs and cannot stare at bright light, and the blood pressure of the patients is increased to influence the operation process. The emotional condition of the patient can be known by measuring the blood pressure of the patient. However, some patients also have a "white gown syndrome" which, in the face of unfamiliar circumstances, faces and sounds, plus unfamiliar with the manner of surgical treatment, causes more adverse emotional reactions in the patient, such as anxiety, fear, and consequently an increase in blood pressure. Consequently, after the patient wears the VR glasses, adopt artery blood pressure monitor to monitor the patient under the condition that is sheltered from by the vision, the data of obtaining are more accurate, through detecting, the stable back of mood of patient's blood pressure, just can carry out the operation. Meanwhile, after the patient is immersed in the virtual operation scene for many times, the patient is well matched, and the blood pressure gradually tends to be normal, so that the actual operation treatment is efficiently completed.
The opening and closing bracket 31 comprises a V-shaped bracket 311, a traction arm 312, a screw 313 and an adjusting nut 314; two arms of the V-shaped support 311 are hinged with a traction arm 312, the traction arm 312 is hinged with the frame body 1, the tip end of the V-shaped support 311 is connected with a screw 313, and the screw 313 penetrates through the frame body 1 through a through hole to be connected with an adjusting nut 314.
The detailed connection relationship among the screw 313, the frame 1, and the adjusting nut 314 is at least two, and other connection methods may be used to achieve the functions. One is that one end of the screw 313 is rotatably connected with the tip end of the V-shaped bracket 311, the screw 313 is connected with the through hole through threads, and the adjusting nut 314 is fixedly arranged at the other end of the screw 313. The adjusting nut 314 is rotated to drive the screw 313 to rotate, so that the length of the screw 313 in the frame 1 can be adjusted, the tip of the V-shaped support 311 is driven to move, and the V-shaped support 311 can be opened and closed under the action of the traction arm 312. The other is that one end of the screw 313 is fixedly connected with the tip of the V-shaped bracket 311, a gap is left between the screw 313 and the through hole, and the adjusting nut 314 is sleeved on the screw 313 outside the frame 1. A gap is reserved between the screw 313 and the perforation to be more beneficial to the floating of the eyelid retractor 3, and the length of the screw 313 in the frame body 1 can be adjusted by rotating the adjusting screw 314, so that the V-shaped support 311 is driven to open and close. The opening and closing support 31 is made of metal, and the screw 313 is further connected with an electrode. The electrode is connected with the power, and the power adopts the voltage to human safety, and when turning on the power, the electrode can discharge, and is the same with the electrotherapy principle, but the setting of this application electrode is for producing the amazing sense of stinging to the eye, lets the patient experience the sense of stinging in the adaptation operation process.
