Fig. 1-3 are refer to, present embodiments provide a kind of induction system 100 of miniature support, it includes shell 110, released
Put device and miniature support 190.
Wherein, " miniature support " refers to overall length 5-8mm, and maximum outside diameter 550um, Biocompatibility is good, and can
The rack for operation for coordinating intervention silk 140 to deform upon.
Shell 110 is substantially threadedly coupled in elongated cylindrical shape and including handle end 112 and output end 114, output end 114
There is capping 120, perforation is provided with capping 120.
Release device is arranged in shell 110.Release device includes drive block 130, backstop pipe 122, intervention silk 140, pressure
Contracting block 150, spring 160, released strip 170 and actuator 180.Length direction of the drive block 130 along shell 110 is slidably connected to
In shell 110.Backstop pipe 122 is fixedly connected through the perforation for covering 120 and with capping 120, and it is predominantly located in outside shell 110
Portion, remainder are located inside shell 110.
Intervention one end of silk 140 is fixedly connected with drive block 130, and the other end stretches out shell 110 by the inner chamber of backstop pipe 122
Output end 114.The position that intervention silk 140 be located at the outside of shell 110 and stretches out backstop pipe 122 curved (has necessarily
Curvature).
Compression blocks 150 are slidably connected in shell 110 and between drive block 130 and cappings 120.Compression blocks 150 are set
Lug boss is equipped with, the shell wall of shell 110 is provided with the chute and neck matched with lug boss.The length direction of chute and shell 110
Length direction it is identical, neck is communicated in the one end of chute away from output end 114.
The one end of spring 160 props up the one end of compression blocks 150 away from output end 114, and the other end props up drive block 130 close to defeated
Go out the one end at end 114.
Released strip 170 is the elastic strip of bending, and its one end props up the one end of drive block 130 away from output end 114, another
End props up the block of the inwall of shell 110.
Actuator 180 can use various structures, and in the present embodiment, actuator 180 is button, the rotation connection of button one end
In the shell wall of shell 110, the other end is provided with jackscrew, and the jackscrew can drive the released strip 170 by the rotation of the button
Depart from the block.
Pressing actuator 180 can drive released strip 170 to depart from block, so that drive block 130 is in the presence of spring 160
Slided to handle end 112.
Reference picture 4, miniature support 190 are sheathed on intervention silk 140 and are located at outside shell 110 and stretch out the position of backstop pipe 122,
Because intervention silk 140 corresponding position has certain curvature, thus its can cause miniature support 190 in the form of certain
Intervention silk 140 is fastened under free state, to avoid the miniature operation consent of support 190 from loosening or come off.
Further, the buffer structure 200 for ensureing the sliding stability of drive block 130 is provided with shell 110.It is above-mentioned
Buffer structure 200 can use various forms, and in the present embodiment, buffer structure 200 includes guide 230, traveller 210 and piston
220, guide 230 is fixedly installed in shell 110, and the one end of traveller 210 is connected with drive block 130, and the other end connects with piston 220
Connect, piston 220 is slidably connected in guide 230.Piston 220 slides relative to the inwall of guide 230 will form certain friction resistance
Power, so that drive block 130 slowly can stably slide in shell 110.
Certainly, it is necessary to which explanation, in other embodiments, buffer structure 200 can also take other form, such as existing
Some buffers.Buffer includes sleeve and slide bar, and sleeve is fixedly installed in shell 110, slide bar stretch out sleeve one end with
Drive block 130 connects.
In order to ensure the normal work of miniature support, the output end 114 of the induction system 100 of this miniature support is provided with admittedly
Position feature, it can ensure that miniature support does not fall off or relatively moved.Meanwhile the output end 114 of induction system is also set up
There is a protection device, the effect of the device is that the miniature support of protection does not contact with the external world before surgery and in transportation.
The operation principle of the induction system 100 of this miniature support and the use of process is such：Operation consent, miniature support
190 have been stably installed on intervention silk 140, and now in the raw, drive block 130 is not by spring for spring 160
160 active force (see Fig. 1)；During operation, the lug boss of compression blocks 150 is promoted first along slide, so as to drive compression blocks
150 slide with compression spring 160 to handle end 112, and when lug boss slides into neck, rotation lug boss makes it be caught in neck
It is interior, so that spring 160 keeps compressive state (see Fig. 2), intervention silk 140 and miniature support 190 are then inserted into patient's eye
Portion's region of interest, actuates actuator 180 afterwards, pressing keys, and the jackscrew on button can promote the respective end of released strip 170 to take off
From block, after losing the stop of block, under the active force of spring 160, released strip 170 and drive block 130 will be to handle ends
112 slide, and due to the active force of buffer structure 200, drive block 130 will not produce shake because of the power of spring 160, but slowly
Stably slide, so as to drive intervention silk 140 also slowly stably in retraction shell 110, and be installed on the miniature of intervention silk 140
Support 190 can then be blocked by backstop pipe 122 and can not retracted in shell 110, so as to depart from from intervention silk 140 and stay in patient
The corresponding position (see Fig. 3) of eye, finally intervention silk 140 is extracted from patient's eye.
In summary, the induction system 100 of this miniature support includes shell 110, release device and miniature support 190,
Shell 110 includes handle end 112 and output end 114, and release device is arranged in shell 110, and release device includes intervention silk 140
With actuator 180, output end 114 is stretched out in intervention silk 140 one end, and miniature support 190 is sheathed on intervention silk 140 and is located at shell 110
Outer position, actuator 180 are connected with release device, and actuating actuator 180 can make release device discharge miniature support 190, by
Just it is pre-installed on before surgery in induction system in the miniature support 190 of this induction system, and no longer needs extra servicing unit
Individually storage, can effectively prevent miniature support 190 from loading failure loosening because occurring during transport or use, so as to protect
Card operation smoothly completes, the defects of effectively compensate for prior art.
Meanwhile in the prior art, because miniature support is usually miniature support, it is extremely tiny, thus loader plus
Work manufacture difficulty is big, and operating procedure increases, and the increase of device, can undoubtedly have high requirements to operation technique.And this skill
In art scheme, because in implementation process of performing the operation, miniature support with being fixed on a kind of induction system 100 of miniature support in advance
Intervention silk 140 on, during operation, induction system only needs once to be inserted into intraocular can and completes operation, and buffer structure 200
Presence ensure that release device can stablize miniature support is stayed in into patient's body, improve the success rate of operation.
Preferred embodiment of the present utility model is these are only, is not limited to the utility model, for this area
Technical staff for, the utility model can have various modifications and variations.It is all within the spirit and principles of the utility model,
Any modification, equivalent substitution and improvements made etc., should be included within the scope of protection of the utility model.
