Description
Technical field
The present invention relates to technical field of medical instruments, is a kind of auxiliary pusher, especially refers to implant in a kind of folding assisted formula artificial vitreous's art the device of vitreous chamber.
Background technology
The nature vitreous body accounts for 4/5 of eyeball volume, is a kind of transparent gelinite, has thin film to surround outward, and physiological function mainly is to support retina, refraction of eye, barrier cell and nutrition etc.Because vitreous body can not be regenerated, when vitreoretinal diseases takes place, during as detachment of retina, proliferative vitreoretinopathy (PVR), proliferative diabetic retinopathy (PDR) and endophthalmitis, must extract the nature vitreous body and fill suitable artificial vitreous, to repair ocular injury, support retina, rebuild visual function and prevent ophthalmatrophy.
Numerous to artificial vitreous's research both at home and abroad at present, mainly contain noble gas, silicone oil, heavy silicone oil, perfluorocarbon liquid, and the hydrophilic high molecular polymer hydrogel etc., but their therapeutic effect is all not satisfactory.As present clinical practice silicone oil substitute more widely, can cause cataract and glaucoma, and itself can must take out after the emulsifying at the regular hour internal emulsification, easily take place to break away from once more and take out the back retina.Present artificial vitreous, method for implantation all is in art it directly to be injected into vitreous chamber, supports retina, prevents that retina breaks away from again.Their occupation mode (for example silicone oil) is easy to generate that ophthalmic toxicity, ophthalmic are unordered to flow and take out critical defect such as difficulty, and the ophthalmologist can not be controlled.
Therefore, we change thinking, propose to substitute the Vitrea New Policy-foldable artificial glass of nature, and it mainly is made up of sacculus, drainage tube and drain valve.By mini-incision sacculus portion is implanted to vitreous chamber, injects flow media subsequently, as normal saline, silicone oil, hydrogel etc., the thin film sacculus that forms the vitreous body shape supports retina, filling eyeball, and drain valve is fixed under the conjunctiva subsequently.Owing to have thin film to recover the Vitrea profile of nature, and limited flowing of the interior medium of capsule, overcome present artificial vitreous's ophthalmic toxicity and unordered mobile shortcoming; It regulates intraocular pressure in addition, does not change refraction of eye degree (after filling normal saline), and patient's postoperative keeps normal posture, and plurality of advantages such as medicament slow release function have shown good prospects for application.
But, we find, in the process of implanting sacculus, use apparatuses such as general ophthalmology microforceps, the vascular forceps folding artificial vitreous of clamping well, thereby be not easy it is sent into vitreous chamber once smoothly, turnover is organized and retina near then damaging otch easily repeatedly, simultaneously, after the artificial vitreous is sent into vitreous chamber, apparatuses such as microforceps also are not easy to withdraw from, and therefore need a kind of special pusher that can easily and safely the artificial vitreous be implanted smoothly vitreous chamber of design.
Summary of the invention
The objective of the invention is to overcome prior art equipment can't fine clamping foldable artificial glass, the technical problem that can not withdraw from smoothly again after used assistive device is sent into, the auxiliary device instrument that provides a kind of and make things convenient for, safely and steadly foldable artificial glass sent into.
For realizing above purpose, the present invention has taked following technical scheme: the foldable artificial glass injector, comprise sleeve pipe and be inserted in the sleeve pipe and can before and after pass inject bar, the described bar of injecting comprises injecting body and being separately positioned on and injects injecting head and injecting handle of end, body two ends; Described sleeve pipe comprises body, is provided with casing head in body one end end, and the mouth of pipe front end of casing head is connected with allocation tongue, is connected with grab handle at the other end of described body, describedly has the skylight near on the body of grab handle.
The foldable artificial glass that folds is put into sleeve pipe from the skylight, sleeve pipe front end allocation tongue is vertically inserted scleral incision, can inject, the head of injecting of injecting bar inserts in telescopic grab handle, inject head and pass through grab handle, skylight, body successively, injecting under the thrust of bar, foldable artificial glass is steadily to front slide, through injection port, allocation tongue and the otch of casing head, safety enters vitreous chamber and preliminary the expansion; The structure of grab handle is convenient to fixedly injector; Allocation tongue helps auxiliary fixedly artificial vitreous to inject the position of vitreous chamber; Main feature of the present invention is, can be easily with foldable artificial glass according to the certain orientation stability and safety send into vitreous chamber, also can be used for the propelling movement of other similar products.
Described vertical view of injecting head is trapezoidal, injects the last base 1~10mm of head, bottom 2~20mm, and high 1~20mm, its trapezoidal gradient is 5 °~85 °, its shape, size make it can smoothly enter the sleeve pipe head; Inject the long 30~300mm of body, wide 2~20mm, high 1~20mm; Injecting handle is to be positioned at the part of expanding of injecting the body rear portion, firmly stable when conveniently injecting, and injects the thick 0.1mm~5mm of handle, wide 2~25mm, long 3~30mm; Inject bar total length 32~320mm.
The vertical view of described casing head is trapezoidal, and it is suitable with size, the shape of injecting head, base 1~12mm on the casing head, bottom 2~25mm, high 1~25mm, 5 °~85 ° of its trapezoidal gradients; Side view is a rectangle or trapezoidal; Long 10~the 300mm of body, outer wide 2~25mm, outer high 1~25mm, inner width 2~20mm, interior high 1~20mm; The long 30mm of grab handle, outer wide 2~25mm, outer high 1~25mm, inner width 2~20mm, interior high 1~20mm, the high 5~50mm of the handle wing before and after it, wide 5~80mm, thick 0.1mm~8mm; Sleeve pipe total length 20~320mm.
Described allocation tongue links to each other with the base of the casing head mouth of pipe, wide 1~10mm, and level is stretched out 1~20mm forward.Its width is according to artificial vitreous's type and the decision of operation needs, smaller or equal to operative incision length,, therefore can guarantee that the artificial vitreous accurately enters vitreous chamber through cutting part to insert cutting part, and in bolus infusion processes, play the effect of fulcrum, improve the stability of bolus infusion processes.
On the body front portion, also be provided with in order to observe body and inject the observation window of situation.--the sleeve pipe body front portion of this foldable artificial glass injector can be as required if do not establish observation window; Observation window can be rectangle, ellipse, streamlined, or other satisfy the shape of functional requirement; Observation window can adopt edge formula, the transparent organic or inorganic material of embedding formula, or does not insert any material.
The present invention compared with prior art has following advantage:
1, simple to operate, easy to use.
2, bolus infusion processes is steady, accurate positioning.The head of injecting of injecting bar inserts in telescopic grab handle, inject head and pass through grab handle, skylight, body successively, injecting under the thrust of bar, foldable artificial glass is steadily to front slide, through injection port, allocation tongue and the otch of casing head, safety enters vitreous chamber and preliminary the expansion; Allocation tongue inserts and is fixed on scleral incision, plays the effect of fulcrum in the bolus infusion processes, improves the stability of bolus infusion processes; The structure of grab handle is convenient to fixedly injector.Whole bolus infusion processes can be easily with foldable artificial glass according to the certain orientation stability and safety send into vitreous chamber; Allocation tongue vertically inserts scleral incision, helps auxiliary fixedly artificial vitreous to inject the position of vitreous chamber, guarantees that the artificial vitreous accurately enters vitreous chamber through cutting part;
3, safety is difficult for foldable artificial glass and ocular tissue are caused damage.
