Abstract

The utility model relates to a retinal transplantation head. The utility model is characterized in that the utility model is composed of a conveying pipe, a material storage tube, a first inlet, a second inlet, a propelling tube and a push rod; the conveying pipe is communicated with the material storage tube; the front end of the conveying tube is bent into a thin tube which forms 30 DEG with the level; the material storage tube is connected with the propelling pipe, and is arranged between the first inlet and the second inlet which are arranged on the conveying tube and the propelling tube; the first inlet is a short tube structure which is parallel with the bending front end of the conveying tube; the second inlet is a short tube structure which has same length corresponding to the first inlet. The utility model is mainly used for conveying transplantation liquid. The propelling tube comprises an outer plastic tube wall and an ultra-thin stainless steel tube which is arranged in the outer plastic tube wall. The interior of the stainless steel tube is provided with the push rod. The free stroke of the push rod is 20-25 mm in the propelling tube. The utility model has the advantages of simple structure, convenient operation by doctors and operation time saving, and is simultaneously favorable for patients.

Description

The retina transplantation head
This utility model relates to a kind of ophthalmologic operation instrument, exactly relates to a kind of retina transplantation head.
At present, the retina transplantation device is because structural design is unreasonable, thereby brings inconvenience for doctor's operation, and the effect of each control member is single, fails to make full use of the structural behaviour of each member, and causing is uneconomically to use inconvenience to wait some shortcomings again.
Purpose of the present utility model overcomes the deficiencies in the prior art exactly, and a kind of novel retina transplantation head is provided, and the retina transplantation head of this utility model brings great convenience can for doctor's operation, has saved the operating time, also is of value to patient simultaneously.
The purpose of this utility model realizes by following technical proposals, retina transplantation head of the present utility model is by carrier pipe, the storing pipe, first import, second import, propulsion tube and push rod constitute, wherein carrier pipe is connected in the storing pipe, this carrier pipe is the crooked tubule that becomes 30 ° with level of front end, it is mainly taken charge of and enters in the eyeball and the effect of graft passage, the storing pipe is connected to propulsion tube and between first import and second import on carrier pipe and the propulsion tube, its storing pipe is mainly taken charge of presetting of graft and is retained, described first import is the short tube structure parallel with the carrier pipe bent front ends, it is mainly taken charge of graft is sent in the carrier pipe, second import is a length identical short tube structure relative with first import, it mainly takes charge of the conveying effect of transplanting with liquid, propulsion tube partly includes an outer plastic tube wall and a built-in ultrafine stainless steel tube, in its stainless steel tube, push rod is arranged, it takes charge of the effect of propelling movement and pumpback graft, and the free travel of its push rod in its propulsion tube is 20-25mm.
In use, at first push rod is placed in the propulsion tube, seal first, second import simultaneously; Import 1/2 volume of liquid by second import then, will treat that from first import graft delivers in the storing pipe, seal first import, by second import that liquid in pipe is full, and by delivery pipe section with the air emptying; At last putting back-end is connected on the retina transplantation device by specific device, operation can undergo surgery.
The utility model has the advantages that simple in structurely, the doctor is easy to use, has saved the operating time, also is of value to patient simultaneously.
Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein
Fig. 1 is the generalized section of retina transplantation head of the present utility model.
Referring to accompanying drawing, retina transplantation head of the present utility model is by carrier pipe 1, storing pipe 2, first import 3, second import 4, propulsion tube 5 and push rod (not drawing among the figure) constitute, wherein carrier pipe 1 is connected in storing pipe 2, this carrier pipe 1 is the crooked tubule that becomes 30 ° with level of front end, it is long that it is mainly taken charge of and enters in the eyeball and the effect of graft passage for 38mm, storing pipe 2 is connected to propulsion tube 5 and between first import 3 and second import 4 on carrier pipe 1 and the propulsion tube 5, its storing pipe 2 is mainly taken charge of presetting of graft and is retained, described first import 3 is the short tube structure parallel with carrier pipe 1 bent front ends, and it is mainly taken charge of graft is sent in the storing pipe 2, and second import 4 is a length identical short tube structure relative with first import 1, it mainly takes charge of the conveying effect of transplanting with liquid, propulsion tube 5 parts include an outer plastic tube wall and a built-in ultrafine stainless steel tube (marking among the figure), in its stainless steel tube push rod are arranged, and it takes charge of the effect of propelling movement and pumpback graft.
