Description
Technical field
The present invention relates to a kind of operated eye training simulators, espespecially a kind of can allow eye doctor do simulated exercises continuous curvilinear capsulotomy operation simulation device.
Background technology
The effect of eyes is by transmission ray, through being called the clear outer of cornea, and by crystalloid crystalline, being focused to by image on retina and provides eyesight; The quality of image focused on is subject to multifactorial impact perhaps, comprises size and the shape of eyes, and the transparency of cornea and crystalline; When crystalline because of aging, uv damage or other factors become muddiness even harden less opaque time, light and image will be caused cannot to be sent on retina, cause the dimness of vision, just cataract has been suffered from representative.
Cause cataractous reason to be multiple, cannot be treated with single liquid medicine, can only postpone the speed that cataract is carried out at most, up to now, operation is unique effective cataract therapy method.Whether Modern cataract surgery is all linked with one another on operating procedure, the success or not of each step, all can affect follow-up operating procedure and carry out smoothly; In pioneering operation [CataractExtraction], phacoemulsification [Phaco] is current safest operation, in operation, there is the action of a capsulorhexis, namely continuous curvilinear capsulotomy [the continuouscurvilinealcapsulorrhexis of anterior lens capsule, hereinafter referred to as CCC] step, this is the primary committed step of whole cataract operation, it provide an entire anterior capsule annular opening, guarantee the integrality of apparatus suspensorius lentis and peripheral cyst membrane, ensure the stability of intraocular lens in pouch; Its success completes, and will directly affect carrying out smoothly of whole cataract procedure.The operation tool of capsulorhexis is Tweezers for eye surgery or discission needle, and because the use of Tweezers for eye surgery is relatively good for the control of cyst membrane, therefore to beginner advantageously, therefore in following discussion, we are by the use instrument using Tweezers for eye surgery as CCC.
Clinically, maturity stage, the cataract of old people of overripe stage and part congenital cataract, traumatic cataract, in the operation of nuclear cataract etc., be difficult to differentiate capsulorhexis mouth edge, therefore the CCC that will complete a standard has suitable difficulty, this is because during cataract operation, can first in the side of transparency cornea, cut out an otch, to carry out follow-up action, along with the continuous progress of medical science and technology, the position of otch is transferred to cornea from sclerocornea, the size of otch also from before 12mm, 6mm, 3 to 3.5mm, reduce until current 1.8 to 2.2mm gradually, and will in a so little scope, carry out CCC action, just certain difficulty is had on applying.
Therefore, execute the simulated training that patient often must carry out Cataract Surgery, the success rate of operation that could improve CCC like this, and current simulated training mode, mainly by executing art training to artificialvision or animal eyes, but this training patterns not only cost is high, execute art also inconvenient, and training is to the level that can be patient Shi Shu, its overall time that will spend is very tediously long, the more important thing is after training completes, still need constantly to repeat, contact, otherwise the success ratio of CCC still can decline, so just quality of medical care can be reduced, to again train, but the medical time that doctor is too much is easily taken.
Secondly, traditional CCC training patterns, really can not reflect and patient's eyes executes art situation, because the alternative eyes used in training is artificialvision or animal eyes [such as pig eye], and though these two kinds of alternative eyes can allow trainee learn basic art technology of executing, but in patient's eyes, Shi Shushi cannot be suitable for smoothly backward, because human eye is in surgical procedure, eyeball is subject to the impact of eyeball muscle and frequently rotates, but artificialvision or animal eyes can not rotate, art level can be executed in patient's eyes so will train, not so easily and easily.
Just because of this, the training of CCC or retraining, need to use a large amount of artificialvisions or animal eyes, if with artificialvision's training, cost can be very high, trains with animal eyes, though cost is low, but during training, animal eyes smell easily affects and executes patient, and the eyes of animal more have preservation not easily, can not the problem of long-term storage.
Therefore, how to provide one that doctor can be allowed to be convenient to training application and reusable, again can reduce training cost and apply easily, without preservation problem, more can the operated eye training simulators of Reality simulation eyes, just become the problem of the present invention for improvement.

To describe in detail according to embodiment shown in the drawings below:
As shown in Figure 1 to Figure 3, disclose a kind of operated eye training simulators 100 in figure, be mainly made up of pedestal 1, hollow sphere 2, elastic parts 3, location lamellar body 4, film lamellar body 5, location plug-in unit 6, another collocation Tweezers for eye surgery 200 is implemented.
Above-mentioned pedestal 1 comprises, and upper end has accommodation cell body 11, below has base 14 and be positioned at the middle support 15 connecting accommodation cell body 11 and base 14; Supported by this support 15 and hold cell body 11, to be located at suitable height and position, be convenient to execute patient's exercise; Secondly, this support 15 also as the telescope support of energy adjustment type, to change height at any time, can adapt to the demand executing patient.
Above-mentioned hollow sphere 2, its first half top centre has the perforation 21 of imitation pupil, and Lower Half is then placed in above-mentioned accommodation cell body 11, and can as the rotation as eyeball in accommodation cell body 11, therefore hold cell body 11 as eye socket, hollow sphere 2 is as eyeball.
Described accommodation cell body 11 is hollow taper groove, and be provided with notch 111 above it, below is provided with lower notch 112, on this, the diameter of notch 111 is greater than the diameter of lower notch 112, and the porch of going up again notch 111 has one section of isometrical notch 113.When the Lower Half of hollow sphere 2 is inserted in accommodation cell body 11, the transversal line of hollow sphere 2 can be positioned at the position of isometrical notch 113, and the spheroid below transversal line linearly will contact with upper notch 111, thus, just make hollow sphere 2 accommodation cell body 11 can flexible rotating.
Above-mentioned film lamellar body 5, cover above-mentioned hollow sphere 2 first half top end surface, and Durchgangshohle 21 closed, it can simulate anterior capsule, and can replace renewal at any time.
Above-mentioned location lamellar body 4, for bottom surface has the slide of gum, area is greater than above-mentioned film lamellar body 5, and its cover film lamellar body 5 is also pasted at hollow sphere 2 first half top end surface; It has more the hole 41 corresponding to above-mentioned perforation 21, and hole 41 exposes film lamellar body 5.Paste and tear get for ease of finger, this location lamellar body 4 is embodied as good with rectangle, and the gum of lamellar body 4 bottom surface, location, can repeat to tear glutinous.
Above-mentioned location plug-in unit 6, has two pins, and is closely fixed on perforation 21 side of above-mentioned hollow sphere 2.
Above-mentioned elastic parts 3, is at least one, and one end 3a is connected with the bottom of hollow sphere 2, other end 3b is connected with the bottom of above-mentioned accommodation cell body 11, and it can be simulated eyeball muscle and provide involution power, allows hollow sphere 2 be returned original position again after rotation.Eyeball muscle due to the mankind has 6, and therefore the present invention optionally can set up many, and the position of setting to be symmetrical arranged as good, such as, be symmetrical set, or front and back is symmetrical arranged.
Please refer to Fig. 4 to Fig. 5, the present invention practises continuous curvilinear capsulotomy operation for executing patient, it is simulated eyeball by hollow sphere 2,21 comes imitation pupil, elastic parts 3 to simulate eyeball muscle, film lamellar body 5 to simulate anterior capsule to bore a hole, and location lamellar body 4 is used for fixing film lamellar body 5; In exercise process, by Tweezers for eye surgery 200, the film lamellar body 5 in hole 41 is given continuous circular shape and tear, tear diaphragm 51 and annular opening 52 to be formed.Generally speaking, this operative training simulator 100 easily uses, without the problem of preservation, the most important is, the hollow sphere 2 of simulation eyeball, when applying, is subject to pining down and drawing of elastic parts 3, can as the rotation return as true eye, effectively simulate the situation of true eye, allow training with implementation situation closer to.
Secondly, the application of location plug-in unit 6, can simulate the otch of transparency cornea side, be convenient to execute patient and use Tweezers for eye surgery 200 to practise, and so more can be close to the situation of true operation.Owing to using location plug-in unit 6 can exempt scalloping step, and can make to execute patient and be absorbed in exercise continuous curvilinear capsulotomy, so the proficiency and success ratio of performing the operation can be improved.
With reference to figure 6, when executing art, first Tweezers for eye surgery 200 front end is imported in the plug-in unit 6 of location, then carry out continuous circular shape to the film lamellar body 5 in hole 41 to tear, in upper figure, Tweezers for eye surgery 200 will be torn diaphragm 51 and be turned left by the right side and tear up, in figure below, Tweezers for eye surgery 200 will tear diaphragm 51 by tearing up from left to right, therefore in operation, Tweezers for eye surgery 200 must move left and right, because the distance moved left and right must not be too large, therefore to be no more than the spacing of location plug-in unit 6 two pins for principle, in other words, Tweezers for eye surgery 200 can only move between two pins, any pin can not be touched, and can not go to promote location plug-in unit 6, otherwise hollow sphere 2 will be made to produce rotation, so continuous curvilinear capsulorhexis will be failed.
Shown in Fig. 6 is correct continuous curvilinear capsulotomy surgical state figure, execute in art process at continuous curvilinear capsulotomy, in order to require the complete of annular opening 52, and closer to circle, just Rotation of eyeball must be avoided, therefore the otch can not encountering transparency cornea side in art is executed, because once encounter, eyeball will be driven, cause executing art difficulty, more operative failure can be caused time serious, produce sequelae, just because so, when generally can require that continuous curvilinear capsulotomy executes art, after Tweezers for eye surgery 200 stretches into otch and touches anterior capsule 51, must using position at the Tweezers for eye surgery 200 of incision as an imaginary location axle center A, end movement before adjusting Tweezers for eye surgery 200 with this axle center, location A, and locate plug-in unit 6 except substituting except otch, can also allow and execute the existence that patient practises imagination location axle center A, to carrying out continuous curvilinear capsulotomy smoothly.
In the present invention, because of the undesired emphasis of operation that continuous circular shape is torn, therefore in the following description, do not discuss in detail and how to complete the skill and means that continuous circular shape tears.
Shown in the upper figure of Fig. 7, executing patient is just using Tweezers for eye surgery 200 to carry out continuous curvilinear capsulotomy, figure below then discloses incorrect action, namely the right pin of the fore-end touching location plug-in unit 6 of Tweezers for eye surgery 200 is also towards moving right, hollow sphere 2 is caused to rotate clockwise towards the right side, continuous curvilinear capsulotomy will be unsuccessful thus, even if complete continuous curvilinear capsulotomy, is also not really successfully; Otherwise, the left pin of the fore-end touching location plug-in unit 6 of Tweezers for eye surgery 200 is also towards moving right [not shown], and cause hollow sphere 2 to rotate counterclockwise towards a left side, so continuous curvilinear capsulotomy will be unsuccessful, even if complete continuous curvilinear capsulotomy, be also not really successfully.So when hand-held Tweezers for eye surgery 200 is not touched and do not promote to locate plug-in unit 6, just represent that continuous curvilinear capsulorhexis operation makes progress, allow and execute patient oneself and see progress, the operation of continuous curvilinear capsulotomy of being just confident of.
Please join Fig. 1 and Fig. 2 again, for the ease of executing patient's storage and taking Tweezers for eye surgery 200, the posting 12 for location, Tweezers for eye surgery 200 top is set at the side of above-mentioned accommodation cell body 11; And correspondence immediately below posting 12 and be arranged on above-mentioned base 14 position, can for the locating slot 13 of location bottom Tweezers for eye surgery 200.It should be noted that, the just a kind of preferred embodiment of graphic middle disclosed pedestal 1, the enforcement example that it still has other different, as shown in Figure 8, posting 12 for location, Tweezers for eye surgery 200 top is set in the left and right sides of above-mentioned accommodation cell body 11, relatively, arrange the locating slot 13 for location bottom Tweezers for eye surgery 200 in the left and right sides of pedestal 1 respectively, lower to be vertically symmetrical arranged presented by described posting 12 and locating slot 13.Based on above-mentioned, the quantity of posting 12 and locating slot 13 also can increase to more than three, need arrange depending on actual state, but to arrange one to four for good.
