Abstract
The utility model relates to a retinal transplantation device. The utility model comprises a driving, propelling and back pumping part, and a body part. The driving, propelling and back pumping part is composed of a foot pedal device, a driving hydraulic cylinder, a driving hydraulic cylinder, a switching valve, a speed regulating valve and a driving pipeline. The body part is composed of a piston rod, an outer sleeve, a sleeve pipe, a cylinder body, a cylinder body front end, a cylinder body back end, a rotary nut, and a guide pipe. One end of the piston rod is arranged in the cylinder body, and the other end of the piston body extends out of the outer sleeve through the cylinder body front end. The outer sleeve is provided with screw threads, and is assembled with the rotary nut. The interior of the outer sleeve is provided with the sleeve pipe. One end of the sleeve pipe is arranged on the outer diameter of the cylinder body front end. The cylinder body back end is communicated with the guide pipe. The guide pipe is communicated with the driving pipeline. The utility model has the advantages that the body part has good operation follow-up performance and stability, and the operation accuracy and the operation effect are improved.
Description
This utility model belongs to medical apparatus and instruments, belongs to the retina transplantation device of ophthalmic more precisely.
At present in the field of relevant ophthalmology, the ophthalmological instruments that is adopted is often owing to be activated the influence of device, make fully directly control device work of doctor, just must be subjected to the influence of the factor of those operations of accurately and in time carrying out him inadequately, reliability and capacity limit such as complex motor equipment, paraprofessional personnel's the agility and the influence of other factors, meanwhile, the doctor can not be fully and the work of self-operated controller tool causes the safety of intraocular surgery to reduce, can not carry out doctor's decision completely owing to the restriction of technique with the apparatus condition, this has just reduced therapeutic effect.
The purpose of this utility model is to develop a kind of retina transplantation device, and it can make the doctor directly control its grafting device exactly by the structure of the body part of change grafting device.
The purpose of this utility model realizes by following technical proposals, retina transplantation device of the present utility model, it comprises that driving advances and pumpback part and body part, described driving advances and returns shaft portion is by foot-treadle device, drive hydraulic cylinder, resetting means, reversal valve, flow speed control valve and driving pipeline are formed, it is characterized in that body part is by piston rod, overcoat, sleeve, cylinder body, the cylinder body front end, rear end of the cylinder block, swivel nut, conduit is formed, wherein an end of piston rod places in the cylinder body, and the other end stretches out outside the overcoat through the cylinder body front end, puts outward to be provided with screw thread, is fitted with swivel nut on it, one sleeve is arranged in overcoat, this telescopic end is disposed on the cylinder body front end external diameter, rear end of the cylinder block connecting tube, its conduit and above-mentioned driving pipeline connection.
The body part that the utility model has the advantages that the retina transplantation device has good operation servo-actuated and stationarity, has improved the accuracy and the operating effect of operation greatly.
Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein
Fig. 1 is the generalized section of the body part of retina transplantation device of the present utility model.
Now referring to accompanying drawing, retina transplantation device of the present utility model comprises that driving advances and pumpback part (not shown among the figure) and body part (as shown), described driving propulsive units is by foot pedal apparatus, drives hydraulic cylinder, resetting means, reversal valve, flow speed control valve and driving pipeline are formed, and body part is by piston rod 1, overcoat 2, sleeve 4, cylinder body 6, cylinder body front end 5, rear end of the cylinder block 7, swivel nut (not shown), conduit 8 is formed, and wherein an end of piston rod 1 places in the cylinder body 6, and the other end stretches out in outside the overcoat 2 through cylinder body front end 5, overcoat 2 is provided with screw thread 3, be fitted with swivel nut on it, a sleeve 4 is arranged in overcoat 2, an end of this sleeve 4 is disposed on the external diameter of cylinder body front end 5, rear end of the cylinder block 7 connecting tubes 8, conduit 8 and above-mentioned driving pipeline connection.
