Description
Technical field
This utility model belongs to medical instruments field, is specifically related to external coat medical equipment, breeds bar rope eyelid retractor more specifically under a kind of retina.
Background technology
Under retina, breed bar rope and betide proliferative vitreoretinopathy (proliferative vitreoretinopathy after rhegmatogenous detachment of retina, PVR), due to retinal pigment epithelium (retinal pigment epithelial, RPE) give birth to as macrophage, myofibroblast form in subretinal propagation, change, retinal gliocytes also participates in its formation simultaneously.Lewis etc. to 72 routine PVR patients' research in, find that under retina, breeding bar rope is present in 47% patient, part hinders amphiblestroid reset, needs operation to take out.Under surgical procedure retina, the principle of hypertrophy is: under retina, propagation is taken out as far as possible, strictly according to the facts in difficulty, removes the reattachment of retina of loosening.Under retina, the operating technology of hyperplastic tissue is the technology the most difficult in vitreous-body-retina integrated operation, required precision is the highest.
Conventionally in operation, near breeding bar rope under retina, there is retinal hole, can be extracted through former ceasma; As without retinal hole, must under retina, breed near bar rope retina place easy to operate coagulation under water in advance, then retina pore-creating, then extract propagation bar rope through pore-creating place.As far as possible along ceasma tangential direction although breed the extraction of bar rope under retina, but because this operating position is eyeball inner surface, propagation bar rope has traction action and there is to certain dissection at retinal hole edge the retina that is covered in its top, can cause detachment of retina or original extent of retinal detachment to increase, and the expansion of retinal hole, affect surgical effect.Therefore, need to breed bar rope under traction, extraction retina time, at retinal hole place, bar rope is supported, to reduce amphiblestroid damage in operating process.
At present still not for the special apparatus of this operation, most patients are often taking ophthalmic lighting fiber as the strong point, by the tractive that continues to repeat, take out and under retina, breed bar rope.Due to the blunt circle in ophthalmic lighting fiber top, in supporting, cannot fix propagation bar rope, often slippage repeatedly, therefore this operating efficiency is low, also easy damaged retina.
Summary of the invention
The purpose of this utility model is to provide in a kind of 20G vitrectomy bimanualness and carries out breeding under retina bar rope while extracting, under Special medical equipment propagation bar rope being supported at retinal hole place---retina, breeds bar rope eyelid retractor.
