Description
One. technical field
The present invention relates to medical apparatus and instruments, is to be used at the ophthalmology cataract operation, especially the miniature incision cataract operation.
Two. background technology
The modern day cataract operation is in order to reduce in the operation the wound of eyeball, the safety that improves operation and operation efficient, in eyeball, pouring into synchronously, keep under the spatial situation of ophthalmic, adopt within the eye with after the cataract pulverizing, through the operation method of thinner pipeline sucking-off, reach the purpose of Minimally Invasive Surgery again.Common used cataract breaking method, it is the cataract ultrasonic emulsification that utilizes acoustic energy, under it is controlled by the cataract ultrasonic emulsification device, cataract ultrasonic emulsification handle and ultrasonic emulsification syringe needle are as operation tool, ultrasound waveguide is gone in the eyeball, to cataract impact, cavitation etc., make cataract emulsifying and cut apart, become little fragment and chyle shape after, ultrasound waveguide can be gone into the special pipeline sucking-off of eyeball, be finished the cataract ultrasonic emulsification sucking-off operation of miniature incision.
Existing cataract ultrasonic emulsification device, be a kind of in order to adapt to cataract ultrasonic emulsification sucking-off operation overall process, by what control by microprocessor, multi-functional combination control appliance, comprise that (one) attracts control circuit by perfusion, negative pressure source (being generally venturi pump or peristaltic pump), perfusion, attraction pipeline, the pressure transducer that is connected with attraction pipeline side mouth, the electromagnetic switch of compressing perfusion pipeline, perfusion attracts handle or/and cataract ultrasonic emulsification handle etc. are formed---cataract operation perfusion attraction system, (2) based on cataract operation perfusion attraction system, add the ultrasonic energy control circuit, connection cord, the ultrasonic emulsification handle of internal placed transducer and the first-class composition of Phacoemulsification needle thereof---the cataract ultrasonic emulsification system, and cooperate operation to finish, (3) based on cataract operation perfusion attraction system, add the vitrectomy control circuit, gas source connector/or air pump, electromagnetic valve, source of the gas delivery hose and the first-class composition of vitrectomy---vitrectomy system and (four) are specifically designed to the operative incision hemostatic---electricity coagulates system.More than each system an independent working mode of the same name is all arranged, help operation to finish cataract perfusion attraction, cataract ultrasonic emulsification, vitrectomy and electric coagulation hemostasis respectively.The mode of operation of equipment extremely relevant parameter is adjusted by control panel and is shown, cataract ultrasonic emulsification handle, vitrectomy head, electric coagulation forceps etc. are as execution unit, multi-functional backpedalling brake all is connected with corresponding interface, joint on the main frame with corresponding pipeline as control assembly, after determining good berth pattern and relevant parameter on the control panel, control its switch and size during work by multi-functional backpedalling brake.
In fact, in operation, because hyperacoustic physical characteristic makes the cataract ultrasonic emulsification operation usually severe complications may take place, as:
When the cataract ultrasonic emulsification sucking-off is performed the operation, because hyperacoustic physical characteristic, determined should operation can the appearance complication relevant with the energy size with action of ultrasonic waves, as the action of ultrasonic waves form---impact and cavitation etc., and can be the pencil linear propagation, all be not easy to be seen by operator, be difficult to by operator perception intuitively, and, these effects, do not need the contact of ultrasonic emulsification syringe needle both can take place, make ultrasound wave when having an effect, its sphere of action is not directly perceived, be not easy control, operator is when starting ultrasonic emulsification, its sphere of action is much bigger than actual needs, it not only only acts on cataract, with its pulverizing, simultaneously, by the ultrasonic emulsification syringe needle, the ultrasonic ultrasound waveguide that involves causes vibration of ophthalmic liquid etc., the cutting that is produced, impact, wash away, wherein, especially the vibration of the ophthalmic liquid that causes of ultrasound wave causes, to pulverizing not washing away of too big effect of cataract, to intraocular its hetero-organization, especially the endothelial cell that does not have regeneration capacity, have injury, cataract may take place after capsule break, vitreous body is deviate from, the endothelial cell damage, even come off and forfeiture etc. from original position in a large number, cause the infringement of irreversible visual function and eyeball tissue, and when ultrasound wave takes place, can produce the heat that operation is had only negative interaction, can make cornea burn wound, these all may cause the generation of serious postoperative complication.The generation of these complication is relevant with hyperacoustic cumlative energy size in the operation, in hard cataract operation and surgical technic be not in the operation of very consummate operator, especially obvious, and, this injury, in operation, scarcely can directly show, be not easy in time to be found by operator, make operator, especially the operator in the learning process is at full stretch in operation, sometimes in order to limit hyperacoustic cumlative energy, not having to have to change operation method under the situation about thoroughly cataract being removed, abandon small incision surgery.
At above situation, people have attempted some ways, show division and are analyzed as follows:
(1) for injury that heat caused, change the form that ultrasound wave takes place within the eye by changing the surgical apparatus hardware and software, when ultrasound wave is taken place, the ultrasonic emulsification syringe needle does not produce and only produces very little heat, as so-called cold ultrasonic, solves heating problem, obtained promising result substantially, operation can not cause the irreversible hot injury of organizing substantially again, still, still has low weight hot injury and exists.
(2) for the injury of ultrasound wave to tissue, by a, change the surgical apparatus hardware and software and change the form that ultrasound wave takes place within the eye, as to change sustained wave be impulse wave, control energy size etc. automatically, improves the work efficiency that ultrasound wave is pulverized cataract; B, change operation technique are split nuclear technology as application, use other instruments that cataract is cut apart; With c, improve to attract negative pressure, for the cataract ultrasonic emulsification syringe needle provides bigger shearing force, cut apart etc. cataractous so that the cataract ultrasonic emulsification syringe needle is participated in directly; The use of hyperacoustic energy when cataract being pulverized with the minimizing of trying one's best, by reducing the hyperacoustic energy in the operation, reduce the degree of damage, but, in any case, the damage of using and organizing to energy can only reduce and reduce, and can not avoid the generation of ultrasound wave to eye inner tissue's injury fully.
(3) in order to avoid the injury of ultrasound wave fully to eye inner tissue, people have developed on the basis of ultrasonic emulsification instrument have been increased, laser control circuit under microprocessor control, laser instrument, optical fiber, the cataract laser emulsifying systems that cataract laser emulsifying handle etc. are formed, the cutting that utilizes laser to cause, cataract laser emulsifying sucking-off operation is carried out in plasma explosions etc., but, limited in one's ability because of it, cause operating time to prolong, and corresponding complication occurs, only be applicable to not too hard cataract, laser energy also might injure eye inner tissue simultaneously, therefore, not can be good at extensive popularization.
From last analysis as can be known, at present, pulverize at cataract, also both not harmless to organizing, can finish the method that cataract is pulverized again, and use existing way, as long as there is pair tissue to have the energy of injury to discharge in eyeball, corresponding complication just might take place, therefore, have only the cataract breaking method of employing, could can finish Wicresoft's cataract operation, can avoid the generation of corresponding complication again the no additional injury of tissue.
In addition, facts have proved, no matter be cataract ultrasonic emulsification or the emulsive operation method of laser cataract, all need very long learning cycle, complicated man-machine understanding, man-machine adaptation, man-machine harmony process, operator need be by training for a long time, just can reach eye, the heart, hands, foot coordination, otherwise, severe complications may take place in the operation, therefore, its learning difficulty is big.
