The eye is an extremely important organ for human body, which is located on the head, close to the brain, and has a very complex, delicate and fragile structure, so that the ophthalmic surgery is one of the most difficult surgical operations, and ophthalmologists often need to practice countless times to master related skills to meet the requirement of performing surgical operations on the eyes of real people.

In view of the above, a more advanced technique in the prior art is an ophthalmic surgery simulation training system, which can simulate various ophthalmic surgeries through devices and systems to practice treatment of complications occurring during the surgeries. However, such training systems generally only use magnetic simulated edges associated with the system, cannot use real animal eyes for testing, lack operative strength, are expensive, and are difficult to adequately deploy.

Another kind of comparatively simple traditional technique is for placing the animal eyeball on simple and easy face model, forms ophthalmic surgery model for the exercise, can use real animal eyeball, more is close true to experience, and the cost is lower, more is fit for being equipped with in a large number. However, the face model in the ophthalmic surgery model is generally integrally formed in batch, the shape is fixed and is difficult to freely adjust, and in a real human face, the facial features are diversified, especially the difference between the height of the nose bridge close to the eyes and the height of the forehead, so that the angle, the mode and the like of instrument operation during surgery can be greatly influenced, and the face model with the fixed shape is difficult to meet the requirements. In addition, the face model in the ophthalmic surgery model is often provided with a small hole only for placing and exposing eyeballs at the eye position, so that the animal eyes applied to the ophthalmic surgery model need to completely remove external eye structures such as eyelids, extraocular muscles and the like, only internal eyeballs are left, the difference between the animal eyes and the clinical actual eye structure is larger, the training range is obviously reduced, and the simulation degree is lower. Therefore, the ophthalmic surgery model in the prior art cannot provide the practice experience closer to the actual human eyes for the doctor, and is not beneficial to the improvement of the medical skill.

Fig. 1 to 4 show a high simulation model for ophthalmic surgery training of the present invention, which comprises a face model 1 and a supporting and adjusting component 2, wherein the face model 1 comprises a forehead part 11, a nose part 12, a lower face part 13 and eye holes 14 which are independent from each other, the lower end of the forehead part 11 is connected with the upper end of the nose part 12, the lower end of the nose part 12 is connected with the upper end of the lower face part 13, and the eye holes 14 are positioned between the forehead part 11 and the lower face part 13 on both sides of the nose part 12; the eye hole 14 is used for accommodating an animal orbit tissue block; the face model 1 is arranged according to the shape of the human face, has the function of providing the user with the operation experience closer to the real human face, generally speaking, the face model 1 is integrally formed into a whole piece in a mould by adopting silica gel, small holes are arranged at the positions of the eyes, for exposing animal orbital tissue mass (e.g., porcine orbital tissue mass) there, but in practice, the facial form varies from person to person, wherein the two parameters of the height of the nose bridge and the height of the forehead have great influence on the operation of the ophthalmic surgery because the nose bridge and the forehead are close to the eyes, if only a model of the nose bridge and the forehead with a single fixed height is used for practice, in practice, the face of the patient is found to be very different, it takes a certain time to adapt, the procedure performed during this adaptation may cause irreversible damage to the patient's eye. In view of these reasons, the face model 1 in this embodiment sets the forehead portion 11, the nose portion 12 and the lower face portion 13 as independent components in order to facilitate the adjustment of the heights of the nose bridge and the forehead protrusion, so that the heights of the forehead portion 11 and the nose portion 12 can be independently adjusted, thereby simulating the bridge of the nose and the forehead of various patients and creating different exercise difficulties. In addition, in the embodiment, the elastic layer is preferably covered on the surfaces of the nose bridge and the forehead, so that the elastic layer is used for simulating the elastic skin to provide real touch feeling, and the phenomenon that obvious separation is seen by naked eyes when the heights of the nose bridge and the forehead are different greatly and the simulation degree is influenced is avoided.

In cooperation with the above-mentioned face model 1, the support adjusting assembly 2 is supported on the inner sides of the forehead portion 11 and the nose portion 12, and the support length of the support adjusting assembly 2 can be adjusted, so as to adjust the protruding height of the forehead portion 11 and/or the nose portion 12. The supporting and adjusting component 2 provides basic support for the face model 1 on one hand, so that the face model can be placed at a certain height, on the other hand, as the supporting height is adjustable, when the supporting height becomes high, the protruding height of the supported part can also be changed, so that two factors which have great influence on the operation and are different in the height of the nose bridge (namely the nose 12) and the height of the forehead (namely the forehead 11) can be simulated, the practice is more comprehensive, after the model is used for practice, the optimal angle and mode of the ophthalmic operation can be well mastered when patients face different heights of the nose bridge (namely the nose 12) and the forehead (namely the forehead 11) in the real operation, and the cure rate of the patients is improved and the incidence rate of medical accidents is reduced. In addition, because the invention does not adopt complicated and high equipment, the manufacturing cost and the use cost are controllable, the invention is very suitable for being equipped in medical institutions such as medical institutions and hospitals in large quantities, and meets the clinical practice requirements of various mathematics doctors. The height adjustment of the forehead 11 and the nose 12 may be performed simultaneously or separately.

In addition, the present embodiment preferably also has a support and adjustment assembly 2 at the eye aperture 14 portion for supporting and adjusting the animal orbital tissue mass, which is adjustable in height when placed thereon. This is because in practice, the sizes and thicknesses of the obtained animal orbital tissue blocks are not necessarily the same, and therefore, in order to make the eye tissues fit the face model 1 as much as possible, the adjustment of the height is important, and a more simulated exercise experience can be provided for the user.

The support adjusting portion in this embodiment is mainly used to adjust the support height, so that there are multiple implementation manners in the mechanical structure, and the technical difficulty is small, which will not be described herein one by one.

The support adjusting part as a preferred embodiment of the support adjusting part comprises two sub support adjusting parts 21 for supporting the forehead part 11 and the nose part 12, respectively, each sub support adjusting part 21 comprises a movable screw 211, a fixed seat 212, a driving gear 213 and a rotating shaft 214, the movable screw 211 is axially movably arranged in the fixed seat 212, and the axial top end of the movable screw 211 is supported on the inner side of the forehead part 11 or the nose part 12; the axial direction of the driving gear 213 is perpendicular to the axial direction of the movable screw 211, and the gear teeth of the driving gear 213 are engaged with the external threads on the side surface of the movable screw 211; the rotating shaft 214 is connected to the center of the driving gear 213, and is used for driving the driving gear 213 to rotate. When the rotary shaft 214 rotates forward, the driving gear 213 is driven to rotate forward, and the movable screw 211 is driven by the driving gear 213 to move upward along the axial direction due to the engagement of the movable screw 211 and the driving gear 213, so that the protruding height of the forehead 11 or the nose 12 supported by the movable screw is increased, and a deeper face contour is formed; conversely, when the rotating shaft 214 rotates reversely, the driving gear 213 rotates reversely, and the movable screw 211 is driven to move downward along the axial direction, so that the protruding height of the forehead 11 or the nose 12 supported by the movable screw is reduced, and a flatter face contour is formed. The support adjusting part enables the height of the forehead part 11 and the nose part 12 to be adjusted more conveniently, and particularly, the support adjusting part is simple in structure, small in size and suitable for being arranged below the face model 1.

The rotation of the rotary shaft 214 in the above-mentioned sub-support adjusting part 21 can be manual or motor-driven, when adopting manually, the one end of the rotary shaft 214 with the drive gear 213 is connected, and the other end is followed the side of the face model 1 stretches out and is equipped with the knob 215, only need when needing to adjust from the side rotary knob 215 can, neither need take away the face model 1, do not influence the front operation again, and need not connect the electricity and leave the position that sets up motor or motor, the flexibility is stronger. When the motor-driven scheme is adopted, the sub-support part further comprises a driving motor and a switch (not shown in the figure), the driving motor provides power for the rotation of the rotating shaft 214, the switch is electrically connected with the driving motor and is used for controlling the on and off of the driving motor, and the switch is used for controlling the operation of the driving motor.

In addition, the adjusting and supporting device can also directly adopt an air cylinder mechanism which can directly control the displacement of the nose part 12 and the forehead part 11 in the height direction, the assembly is simpler, and the adjustment is more intuitive.

In order to fix the position of the animal orbital tissue mass after being accommodated in the eye aperture 14 and avoid displacement and influence on the operation precision during the operation, the present embodiment preferably further comprises a positioning assembly, one end of which is connected to the forehead portion 11 and/or the lower face portion 13, and the positioning assembly fixes the animal orbital tissue mass from at least one direction of the forehead portion 11 and the lower face portion 13, and the other end of which extends out of the eye aperture 14 and is used for clamping and pressing the animal orbital tissue mass placed in the eye aperture 14.

As a preferable mode of the positioning component, the positioning component includes a pressing piece 3 and a torsion spring, one end of the pressing piece 3 is hinged to the forehead portion 11 and/or the lower face portion 13 through the torsion spring, so that the other end of the pressing piece 3 has an elastic force towards the inner side of the eye hole 14, when in use, the pressing piece 3 is firstly pulled outwards against the elastic force of the torsion spring, then the animal orbital tissue block is placed into the eye hole 14, the pressing piece 3 is placed after the position is adjusted, under the elastic force of the torsion spring, the pressing piece 3 presses the animal orbital tissue block in the eye hole 14, so that the animal orbital tissue block is difficult to move, and the position of the pressing piece 3 is preferably at a position avoiding the eyeball, so as to prevent the pressing piece 3 from influencing the operation.

As another preferable mode of the positioning assembly, the positioning assembly includes a pressing screw and a nut, the outer side of the nut is fixed on the outer side of the forehead 11 and/or the lower face 13, one end of the pressing screw is screwed into the nut in the direction of the eye hole 14 with an axis, the other end of the pressing screw extends towards the eye hole 14, the pressing screw is higher than the height of the animal orbital tissue block, when in use, the pressing screw is firstly screwed out to a position far away from the eye hole 14, so as to avoid the interference of the pressing screw on the placement of the animal orbital tissue block, and when the animal orbital tissue block is placed in place, the pressing screw is screwed in the direction of the eye hole 14, so as to press the animal orbital tissue block thereunder to play a fixing role.

Referring to fig. 3 and 4, which are schematic views after the orbital tissue mass of an animal is mounted, it can be seen that another important technical feature different from a general ophthalmic surgery model is that the top of the nose portion 12 in the present invention is an eyebrow center 15, and the lower end of the forehead portion 11 is higher than the eyebrow center 15; the upper end of the lower face part 13 is not higher than the nasal wing of the nose part 12, so that the eye hole 14 at least covers the orbit range of the face model 1, and compared with the general face model 1 which can only be provided with the next isolated eyeball, the range of the eye hole 14 in the face model 1 is greatly increased, so that the eye hole can accommodate a larger animal orbit tissue block, therefore, the animal orbit tissue block used in the embodiment can comprise structures such as an orbit bone, an eyelid, an eyeball, an extraocular muscle, an intra-orbit soft tissue, an optic nerve and the like, and the complete animal orbit tissue block can provide an experience which is closer to the actual operation when the operation is performed. For an operation model with only eyeballs, the effect can be greatly improved; due to the fact that the orbit bone support is complete, operation practice on parts such as eyelids is facilitated, and compared with an operation model with eyelids outside the eyeball, the orbit bone support device can prevent the defects that eye tissues are easy to deform and change in tissue tension in the actual operation process and the observation of operation effects in eyelid operations is affected due to the fact that eye tissues lack effective orbit wall support. And the animal orbit tissue block with the orbit is hard in orbit bone, so that the animal orbit tissue block is difficult to penetrate through a common puncture method, the method such as pressing, clamping and pressing is simpler and easier to operate, a larger range is used for pressing, clamping and fixing, and the animal orbit tissue block with the orbit is not easy to press the eyeball to cause eyeball damage.

As a preferable scheme of further shape and position of the eye apertures 14, the left and right sides of the nose portion 12 are respectively provided with one eye aperture 14 for surgical practice of eyes, the left eye aperture 14 is in an open left side shape, the right eye aperture 14 is in an open right side shape, and the semi-open eye apertures 14 facilitate the lateral installation and removal of the large animal orbit tissue blocks including structures such as the orbit bone, the eyelid, the eyeball, the extraocular muscle, the soft tissue in the orbit, the optic nerve and the like, which are applicable to the embodiment. The length of the eye opening is 9cm to 11cm, preferably 10 cm; the width is 6cm to 8cm, preferably 7cm, which is suitable for most animal orbital tissue mass sizes containing orbital parts and the like, especially porcine eye tissue sizes.

In addition, as shown in fig. 5, the present embodiment preferably further comprises a simulated eyeball with a spherical shape, which is used to replace the eyeball in the orbit of the prime mover when the animal orbital tissue mass without the eyeball is received in the eye hole. The orbital tissue blocks used in this embodiment include the eyeball, the extraocular muscle, the orbital tissue, the orbital bone, the eyelid, and other structures, but in the prior practice, only the eyeball is used, and the rest of the tissue is discarded, resulting in a great amount of waste. The simulated eyeball in the embodiment can be placed in the animal orbit with the eyeball removed, so that the simulated eyeball replaces the original eyeball to support the eyelid, and after the simulated eyeball is fixed in the eye hole, the practice of the eyelid and periorbital operation can be conveniently continued, and the residual animal orbit tissue block after the eyeball is removed is fully utilized.

This embodiment is further provided with an orbital simulation member for simulating a human orbit, which comprises a left simulation member and a right simulation member independent of each other, the eye hole comprises a left hole and a right hole, the left simulation member is matched with the left hole and can be placed therein, and the right simulation member is matched with the right hole and can be placed therein. In some ophthalmic surgery exercises, only one-side exercises are needed, so that only the animal orbital tissue blocks are placed in the eye holes on one side, and the eye holes on the other side are generally in an empty state, so that the whole face model lacks of reality. Thus, the present embodiment also provides an orbital simulator that is used to fill the contralateral side while exercising on one side, creating a complete face shape. When the right-side ophthalmologic operation is exercised, the right hole is provided with a real animal orbit tissue block, the left hole is placed in the left hole by adopting a left simulation piece, and the face model is maintained to be in a full-face shape; when the left eye surgery is connected, the real animal orbit tissue block is installed in the left hole, and the right simulation piece is placed in the right hole to maintain the face model to be in a full-face shape. It can be seen that, after the orbital simulation piece in the embodiment is adopted, more diversified, more adjustable and more real-fit operation practice experience can be provided.

In order to avoid the issue of fluid and the washing fluid during the operation and increase the difficulty of washing, the present embodiment preferably further includes a bottom plate 4, the support adjusting assembly 2 is placed in the bottom plate 4, and the bottom plate 4 below can receive the fluid flowing from the face model 1, so as to facilitate the maintenance of the operation environment.

During surgery, after the porcine orbit tissue block is fixed in the eye hole 14, surgical preparation can be started, a disposable plastic hole towel 5 with the side length of 50cm can be prepared, an oval hole is formed in the center of the disposable plastic hole towel and used for exposing eyes, the long axis of the oval hole is 10cm, the short axis of the oval hole is 6cm, the disposable plastic hole towel 5 covers the porcine eye tissue and the face model 1, the eyes to be subjected to surgical practice are exposed, and a film 6 is pasted on the disposable plastic hole towel to be used as a water-proof layer, so that an ophthalmic surgery scene is fully simulated. It can be seen that the high simulation model in the application can be used for practicing the operation in the preoperative preparation stage, and the effect which cannot be achieved by the traditional ophthalmologic practice model is achieved.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
