The specific embodiment
Followingly describe with regard to the preferred embodiments of the present invention with reference to accompanying drawing.
First embodiment
Fig. 1 is the lenticular insertion system of ophthalmic insertion of the expression first embodiment of the present invention.The figure of upside is a vertical view among Fig. 1, and the figure of downside is a side view.
The 10th, the ophthalmic of present embodiment inserts the insertion utensil with crystalline lens (being designated hereinafter simply as crystalline lens), and the 15th, supply with the feedway of physiological saline and so on liquid 14 to inserting utensil 10.
Inserting utensil 10 is made of body 12 and release axle 16.Body 12 forms as a body component, have a 12a of portion, be arranged on the front end of the 12a of this crystalline lens maintaining part 12b, be arranged on this crystalline lens maintaining part 12b front end the 12c of ozzle portion and be arranged on than the 12a of tube portion more by the handle portion 12e of base end side (opposition side of the 12c of ozzle portion).12a of tube portion and handle portion 12e have hollow structure, release axle 16 and insert its inside.
The writing board shape that crystalline lens maintaining part 12b has hollow, portion within it, crystalline lens 1 is accommodated with the unstressed state that is applied on its optic (part that replaces crystalline lens within the eye) 1a in fact to be kept.Even the said unstressed in fact state that applies is meant long preservation, can not produce the stress that the optical function to optic 1a influences to some extent or the state of distortion here yet.Crystalline lens 1 has optic 1a and support portion 1b, and this support portion 1b is with formation such as wire rods, support this optic 1a within the eye.For can be to crystalline lens maintaining part 12b filling crystalline lens 1, crystalline lens maintaining part 12b has the formation that is separated into two-part formation up and down or switch lid.
In addition, the mode of crystalline lens 1 is not limited to this, also can be to have optic and flat support portion.And, in the present embodiment, the insertion utensil of load mode in advance is illustrated, and promptly this insertion utensil is when dispatching from the factory etc., be seated in crystalline lens 1 in advance among the crystalline lens maintaining part 12b before hospital's delivery, but the present invention also is applicable to insertion utensil in addition.For example, also the present invention can be applicable to and insert utensil and crystalline lens respectively certainly, before being about to undergo surgery, crystalline lens be loaded into the utensil that inserts the utensil formula.
And, in the present embodiment, just have the situation from handle portion 12e to the integrally formed body 12 of the 12c of ozzle portion is illustrated, but insertion utensil of the present invention is not limited to this.For example also ozzle can be installed to enterprising enforcement usefulness from handle portion to the integrally formed body of crystalline lens maintaining part.And, also the parts with ozzle portion and crystalline lens maintaining part can be installed to the enterprising enforcement of the body with a portion and handle portion and use.In any case above-mentioned, owing to after assembling (during use), handle portion as body performance function, therefore, equally all is included in the insertion utensil of the present invention with present embodiment to the ozzle integrally.
Release axle 16 and have the first axle part 16a and the second axle part 16b.Under the state of this first axle part 16a before crystalline lens 1 is inserted ophthalmic, expose from body 12.This second axle part 16b is arranged on the front end of this first axle part 16a, axially extends in body 12.Front end at the second axle part 16b forms crystalline lens contact site 16c.This crystalline lens contact site 16c releases ophthalmic by the 12c of ozzle portion with crystalline lens 1 in that crystalline lens 1 is contacted with the crystalline lens 1 that remains on crystalline lens maintaining part 12b when ophthalmic inserts.
Be formed for inlet 24a that the normal saline from this flexible pipe 13 is poured in the inboard of injection portion 24.And, form the stream 16d that extends from inlet 24a forward end direction (direction of principal axis) in the inside of the first axle part 16a.In other words the front end of this stream 16d is more to lean on the part (pars intermedia) of base end side the space opening in body 12 than the crystalline lens contact site 16c that releases axle 16 at the leading section of the first axle part 16a.This opening port is as the flow export 16e of normal saline in body 12.
Feedway 15 can use by in the bottle that liquid 14 is packed into and liquid level is higher than insert pressure differential that utensil 10 produces, to the device that inserts the utensil supply.And the rinse part that also can utilize the ultrasonic emulsification suction device that generally uses in cataract operation is as feedway 15.
In the insertion system that constitutes like this, if supply with physiological saline and so on liquid 14 from feedway 15 to the injection portion 24 (inlet 24a) that inserts utensil 10, then liquid 14 flows into the inner space of the handle portion 12e of body 12 by the stream 16d in the release axle 16, from flow export 16e.Then, inflow pipe mouth 12c behind inner space by the 12a of tube portion of liquid 14, the inflow crystalline lens maintaining part 12b discharges to the outside from the front opening 12d of the 12c of ozzle portion.
In Fig. 2, hatching is represented the stream of the liquid 14 that the front opening 12d from feedway 15 to the 12c of ozzle portion is communicated with.By suitably setting the flow from the liquid 14 of feedway 15, the direction to the 12c of ozzle portion is mobile always in body 12 can to make liquid 14, and discharges from the front opening 12d of the 12c of ozzle portion.
But, in insertion utensil 10 shown in Figure 1,,, also more form peristome 20 than handle portion 12e by a side of cardinal extremity at body 12 except the front opening 12d of the 12c of ozzle portion as the opening portion of the inner space of body 12.Specifically, on the base end part of body 12, insert cartridge unit 22 with screw division.This screw division is used for by the screw effect release axle 16 being moved to releasing direction when inserting crystalline lens.Between the periphery and body 12 of this cartridge unit 22, form peristome 20 as gap or groove shape passage.But this is to have under the situation of the lid that is divided into two-part formation up and down or switch at crystalline lens maintaining part 12b in order to prevent, liquid 14 in the body 12 flow out from its gap, thereby the part that will the part from crystalline lens maintaining part 12b to handle portion 12e especially grasps is got wet.That is, more discharge from being arranged on, prevent that liquid 14 from spilling from crystalline lens maintaining part 12b, prevent to reduce easily the holding property of inserting utensil 10 by the peristome 20 of base end side than handle portion 12e by making excess liquid 14.
In addition, the peristome that such draining is used is not so long as direct influence the flowing of liquid 14 of answering supply pipe mouth 12c then limited its quantity or size, position.And, also can on the stream towards the 12c of ozzle portion (forming the part of hatching at Fig. 2), connect draining passage with minor diameter that flowing in this stream do not exerted an influence from injection portion 24.
In the inboard of above-mentioned cartridge unit 22, be pressed into from the base end part of body 12 and extend near the front end of the 12a of portion tubular intermediate member 25.And the O type circle 23 of sealing usefulness is installed in leaning on a little on the part of base end part side than flow export 16e in the first axle part 16a of intermediate member 25 inner faces.Therefore, can stop liquid 14 to spill from the inboard of cartridge unit 22.
Like this, if flow export 16e is arranged on the sealing that forms than O type circle 23 tube mouth 12c side a little, then when liquid flows in body 12 from flow export 16e, though a part of liquid flows to the opposition side of the 12c of ozzle portion, but from its very near base end side because by 23 sealings of O type circle, therefore, this liquid 14 flows towards the 12c of ozzle portion at once.
And, according to such structure that flows backwards that prevents, can suppress liquid 14 and near the peristome 20 that draining is used, flow, water is limited in bottom line from spilling of this peristome 20.That is, can prevent that unnecessary liquid from spilling.
In addition, in most cases only use an O type circle 23 not prevent from fully to leak.Therefore, use a plurality of O type circles 23 in the present embodiment.But if use a plurality of O type circles 23, then this O type circle 23 increases with the frictional resistance of intermediate member 25, is difficult to carry out smooth and easy and trickle operation to releasing axle 16.Therefore take following way etc. get final product, promptly pay attention to the break-in facility of leaking, the dilated diameter of an O type circle 23, and dwindle other O type circle 23 diameter, make it can avoid water outflow that spills on a small quantity.That is, by a plurality of O type circles 23 that vary in size being set, can taking into account simultaneously the operation sense of release axle 16 that prevents to leak with appropriateness.
Fig. 3 A and Fig. 3 B represent the section shape of the 12c of ozzle portion.The right part of flg of these figure is to release the section that direction is blocked the 12c of ozzle portion along crystalline lens, the figure in left side be the 12c of this ozzle portion release the orthogonal section of direction with crystalline lens.
At crystalline lens 1 by in the 12c of ozzle portion the time, owing to the existence of crystalline lens 1 causes the space that liquid 14 passes through in the 12c of ozzle portion very narrow and small.Therefore, the flow minimizing from the effusive liquid 14 of the 12c of ozzle portion might can't make the anterior chamber of eyes fully expand.
Therefore, in the present embodiment, shown in Fig. 3 A and Fig. 3 B,, be formed for guaranteeing hole (stream) 28, the groove 29 of liquid 14 flow path areas at all pars intramuralis (being in the thickness of perisporium) or the inner face (inner peripheral surface) of the 12c of ozzle portion.These holes 28, groove 29 extend lengthwise into front opening 12d at the base end part opening of the 12c of ozzle portion from this position.
And, shown in Fig. 3 C, also can form from the base end part of the 12c of ozzle portion to a plurality of rail portion 30 that extends lengthwise into front opening 12d at the perisporium inner face of the 12c of ozzle portion.Crystalline lens 1 one side contact with rail portion 30, one side moves in the 12c of ozzle portion, by like this at the periphery formation of this crystalline lens 1 groove 29 ' as liquid 14 streams.
Like this, even have crystalline lens 1, also can guarantee to flow into by the 12c of ozzle portion the flow of the liquid 14 of ophthalmic from body 12 (12a of tube portion) in the inboard of the 12c of ozzle portion.Therefore, the anterior chamber is fully expanded, can insert crystalline lens 1 swimmingly.
And, shown in Fig. 3 D, also can form following structure: in the 12c of ozzle portion, near the fore-end that inserts ophthalmic, form to the hole of longitudinal extension (stream) 31, in the 12c of ozzle portion, make these hole 31 openings, drain 14 in the perisporium outside of inserting the ophthalmic part at all pars intramuralis of the 12c of ozzle portion.Have the hole 31 of such perisporium outer opening 31a by formation, do not have under the adequately expanded situation,, can make liquid 14 flow in the anterior chambers, this anterior chamber is fully expanded by the 12c of ozzle portion is inserted in the anterior chamber together with this opening 31a the eyes anterior chamber.On the other hand, under the adequately expanded situation of eyes anterior chamber,, make opening 31a be exposed at the eyes outside by only going into ratio open 31a part more on the front among the 12c of ozzle portion to anterior chamber's interpolation, can avoid to avoid anterior chamber's excessive expansion (pressure) in the liquid 14 excessive inflow anterior chambers.That is, only by adjustable pipe mouth 12c to anterior chamber's insertion amount just can controlling liquid 14 to the flow of ophthalmic, with respect to insert crystalline lens can make pressure in the anterior chamber become just when.
In addition, also hole 28 shown in hole shown in Figure 3 31 and Fig. 3 A～Fig. 3 C or groove 29,29 ' can be formed among the same ozzle 12c of portion.
As mentioned above, in the present embodiment, the injection portion 24 that connects flexible pipe 13 is arranged on the base end part of releasing axle 16, if but injection portion 24 and flexible pipe 13 be exposed like this, then be not easy to release the push operation and the rotating operation of axle 16.And 13 distortion hinder to the danger of inserting utensil 10 feed fluids 14 thereby the hands that might exist operation to release axle 16 makes flexible pipe.
Therefore, in the present embodiment, as shown in Figure 1, near the cover 32 the end of covering injection portion 24 and connected flexible pipe 13 is installed on the release axle 16.Axle 16 o'clock are released in operation, hold this cover 32, can not make flexible pipe 13 distortion, operate easily.
The diameter of the flexible pipe 13 that is connected with injection portion 24 has various different sizes.For example, the size of the adapter of the rinse part of ultrasonic emulsification suction device is different, corresponding because of the difference of device production firm, and the size of flexible pipe 13 is also different.And,, then very convenient if can utilize the size of flexible pipe 13 to adjust the flow of liquid 14.
Therefore, as shown in Figure 4, also can the different injection portion 24 of a plurality of sizes (size of attachable flexible pipe 13) be set at the base end part of releasing axle 16.In this case, bolt is set or lid gets final product in the injection portion 24 that does not connect flexible pipe 13.
And, in native system,, therefore, to compare during with the use viscoelasticity part owing to use low-viscosity physiological saline and so on liquid 14, the operation of releasing axle 16 becomes light, thereby might cause release axle 16 is released quickly.Though can avoid unsuitable like this operation to a certain extent by the diameter that strengthens O type circle 23, but still can not avoid fully.
Therefore, in the present embodiment, spring 35 is set at the base end part of body 12 (releasing the periphery of axle 16).Thus, apply resistance, can avoid having unsuitable push operation energetically conscientiously to the push operation of releasing axle 16.
In the native system that can discharge crystalline lens 1 and physiological saline and so on liquid 14, if may command liquid 14 to the influx of ophthalmic, then usability can improve.This is owing at intra-operative various situations might take place, and can carry out correspondence when wanting to set intraocular pressure low when inserting crystalline lens 1 etc.
Therefore, though the hole 31 shown in above-mentioned Fig. 3 D can be formed on all pars intramuralis of the 12c of ozzle portion, but shown in Fig. 5 A and Fig. 5 B, also can near the front opening 12d of the 12c of ozzle portion, be formed on otch 36, the ozzle hole 37 of the perisporium of diametric(al) through tube mouth 12c.Otch 36 is the slit openings that are connected with front opening 12d.In addition, ozzle hole 37 is to separate the hole that forms with front opening 12d.
And, shown in Fig. 5 C, also can release the front opening 12d ' that direction is formed obliquely the 12c of ozzle portion with respect to crystalline lens.
Under the inadequate situation of anterior chamber's expansion, these otch 36 and ozzle hole 37 are inserted in the anterior chamber, maybe the front opening 12d ' that tilts all inserted in the anterior chamber with front opening 12d.
On the other hand, under the adequately expanded situation of the anterior chamber of eyes, be exposed at the anterior chamber outside, can will flow to a part of liquid 14 of the 12c of ozzle portion to the outside discharge of eyes by making at least a portion among otch 36, ozzle hole 37 and the front opening 12d.Can control the amount that flows into the liquid 14 of ophthalmic from front opening 12d, the 12d ' of the 12c of ozzle portion thus.
And,, therefore,, then can conveniently use if can make liquid 14 stop to flow as required owing in operation, there is no need to make liquid 14 to flow always.Therefore, in the present embodiment, as shown in Figure 1, anchor clamps 38 are set on flexible pipe 13, remover-and-replacer 38 can make liquid 14 flow or stop as required.Thus, the use amount of liquid 14 reduces, and can prevent the operating room because the unnecessary liquid 14 of discharge is got wet.
