Description
The present invention relates generally to medical instruments field, more specifically, relates to the surgical instruments field, more distinguishingly, relates to the relevant syringe of operation that is used for injecting with needs visco-elastic material.
The multiple operation that the patient is carried out requires (using syringe usually) to inject biocompatible visco-elastic material or " liquid " (that is high astringency liquid) of set amount, its purpose is to make responsive surrounding tissue to avoid unexpected, the injury that causes by operation, and/or, make it not be subjected to ongoing operating the influence in order to keep or to locate selected tissue.Usually to remove memory fluid after the operation, but in some cases, according to surgical judgement, if continue to stay in the patient body is favourable, if with material be biocompatible cmpd, for example, transparent acidic base materials, it can be absorbed or digest by human body under the condition that has no side effect, and then can stay in the body.
The operating representative type example of this class is, in a kind of operation, a spot of visoelasticity liquid injects patient's intraocular, in this operation, extract damaged or made the patient lose the crystalline lens of the trouble eye of eyesight.Be referred to as in the operating operation of crystalline lens this, be implanted in intraocular to the people crystal (being commonly referred to intraocular lens (IOL)) of faking, to recover patient's eyesight.IOL generally is implanted in original crystalline region ill or damage of having extractd.Typically, but optional, excision may be original crystal of the damage that caused by cataract and implant the IOL that substitutes and finish in performing the operation in same crystal.
In this crystal surgical procedures; usually to inject visco-elastic material with the syringe of a low dose patient's intraocular; so that protect the non-re-epithelialize cellular layer of the sensitivity of cornea effectively; it for example can be subjected to, by the contact of the accident of institute's use apparatus in operation and/or by the fragment of the original crystal that picked-off and/or when IOL implantation intraocular or when locating within the eye by the caused damage of IOL.In separating operation, also can inject visco-elastic material, so that prevent in surgical procedures owing to Vitrea loss causes subsiding of eye.
The most of visco-elastic materiaies that use in this crystalloid operation at present or " liquid " are that mol wt in suitable buffer solution is 500,000 to 2,000, high molecular weight hyaluronic acid between more than 000 (hyaluronic acid), because hyaluronic acid is present in the normal human eye naturally with low concentration, thereby it is a biocompatibility, it has the viscoelastic property of liquid, when measuring with traditional viscosity mensuration, it has about per second 40, the dynamic viscosity of 000cps usually.Representative type hyalomitome acidic group viscoelastic solution is respectively by the Allergan Co., Ltd, Kabi Pharmacia, and Alcon laboratory and Iolab company be VITRAX respectively

Known to the inventor, the injectable medicinal fluid of low viscosity (for example, vaccine inoculation and microbiotic) offer the medical worker with the form that seals (little) bottle usually, before the liquid injection, from bottle, install in the syringe again, in contrast, the memory fluid of the above-mentioned type always in advance by visco-elastic material maker pack into the sterilization disposable syringe in.This is because up to the present, and memory fluid is thanked to astringency and made to be exactly visco-elastic material to be filled into be difficult to very much in the normally used syringe realize.
Yet, only there is " factory's perfusion " memory fluid in syringe can not satisfy many medical professionals' needs, owing to actual reason be at least owing to the operating reason of crystal, syringe all be usually by maker with about 0.4ml to one or both the most frequently used viscoelastic body dosage about 1.0ml in factory's perfusion.
Yet, can not pack into the usually visco-elastic material of accurate dosage of these syringes that pour into visco-elastic material in advance, and this dosage just the surgeon do want or the needed amount of an operation.For instance, if, it is 0.75ml that the surgeon determines for the required visco-elastic material of certain eye surgery, he (she) can only use the some in the 1.0ml syringe, visco-elastic material remaining in the syringe can only abandon, because it can not use another operation again for the reason on the patient safety.
A kind of possible alternative is that the sawbones uses several syringes.Each all is equipped with the visco-elastic material that is less than desired dosage, but meets desired dosage altogether.Yet, this alternative is normally unfavorable, because relate to two, or the extra spending of the viscoelastic body syringe of more a plurality of factories perfusion, this comprises about packing and other spending, and also may be because of requiring additional step and required " time within the eye " (time-in-the-eye).
Another kind of possible alternative is that the surgeon is satisfied with than he (she) and judges required visco-elastic material dosage still less, thereby the single syringe that can use the amount of contained visco-elastic material to lack than desired amount.Therefore repay examination although exist to be satisfied with than what the amount of desired visco-elastic material was lacked, can predict, most of surgeons can think that this alternative is that a kind of surgery that do not meet the specification or unsafe is repaid examination.
Therefore, the most common way is to abandon or discarded very a spot of visco-elastic material in many or most of eye surgeries.This way can not appear at those on the unfamiliar person of the medical reparations policy of the existing strictness that causes very big concern.Yet reality is that all costs relevant with operation all are to be carried out under the audit of strictness by the medical expense compensator, and any rejected material is considered to very undesirable at present at least.
Expense with respect to above-mentioned visco-elastic material waste, the expense of the viscoelastic injector of the factory of above-mentioned size perfusion is at present from being low to moderate the 20-30 dollar to up to 80 dollars, even 100 dollars scope, this depends on quality (reality or noticeable) to a great extent.High like this expense is that the production process by the costliness of the hyaluronic acid that requires to obtain highly purified sterilization (no matter being to be obtained by crest (rooster combs) or biofermentation) is determined.
Therefore, 1/4th of the visco-elastic material in the syringe of staying factory's perfusion that goes out of use constitutes from 7,8 dollars to nearly " loss " between 20 or 25 dollars.Based on single operation, consider the expense of whole eye surgery, as if this quantity is little, yet, only 1,700,000 routine cataract surgery just there is every year in the U.S., suppose that this operation of wherein having only half is 10 dollars of visco-elastic material losses, then the total loss that is caused by discarded visco-elastic material in cataract surgery reaches 8,500,000 dollars.This finally will be paid by the public.
For these and other tangible reason, comprise for convenience's sake and in order to reduce officina (office), the stock of factory's perfusion visco-elastic material syringe of clinic and hospital, the invention provides a kind of device that can on the spot the visco-elastic material in the material supply receiver be filled in the standard syringe, this device make according to the surgeon at the particular surgeries requirement maybe needs the visco-elastic material of exact dose be filled into become possibility in the syringe, and perfusion can be carried out before operation is about to begin.

R) source or supply container 14 pour into conventional injector for medical purpose 12 on the spot.Should be appreciated that term " on the spot " is a broad sense as used herein, means doctor office, Health Service Laboratory or clinic, surgery or operating room, hospital or similar department, they normally patient to be ready standing maybe can stand to use the operating place of visco-elastic material at this.Certainly, device 10 might as well be used for small-sized visoelasticity material manufacturing equipment.
As shown in Figure 1 and Figure 4, syringe clamper 30 comprises halfpipe spare 32, its size is convenient to admit by its open side the syringe part 34 of syringe 12, also has shoulder 36 for said 32, its size is suitable for admitting the finger grips part 38 of syringe, releasable syringe locking folder 40 pivotally is connected to the side regions of part 32, so that pass the open side of part 32 and thus syringe 12 be clamped on the syringe holding frame 30 so that from the perfusion syringe up to by draw back earlier folder take off again the syringe that poured into during this period of time in opposing perfusion power firmly.
Preferably, also just as shown in FIG. 3, liquid pump 60 is ram type pumps, and it has an electrical motor 62 and one and is connected to the head assembly 64 that drives rotationally on the electrical motor by rotating shaft 66.Head assembly 64 comprises a cheese head 68, has on 68 a plurality of by pivotally being contained in pump roller 70 (Fig. 2) on the peripheral portions in relation spaced apart from each other on the circumference each other.As shown in the figure, four such pump rollers 70 are installed with 90 ° interval around pump head 68.
One end of the supporting member 72 of a L-shaped generally rigidity pivotally is installed in the housing 16 near pump head assembly 64 places (Fig. 1 and Fig. 2) by a pivot pin 74, supporting member 72 around pin 74 between make position (Fig. 1 and by shown in the solid line among Fig. 2) and open position (shown in the long and short dash line among Fig. 2) under manual operation pivoted.Because the formation of part 72 and the installation by pivot pin 74, therefore, when part 72 pivotally turns to its open position away from pump head assembly 64 downwards, the curved surfaces 80 of this part and pump head assembly are away from enough distance, so that make conveyer conveyor trunk 52 install or to be inserted between pump head assembly and the part 72.Afterwards, when part 72 oppositely upwards pivotally turns to its make position towards pump head assembly 64, pipe 52 is clamped between the surface 80 of pump head assembly and part 72 (Fig. 2 and Fig. 3).The locking piece 82 (Fig. 1) of a routine releasably remains on part 72 on its make position.
When part 72 be in the close position and by locking piece 82 locking, make the part of pipe 52 be clamped between the surface 80 of pump head assembly 64 and part 72 and pump head assembly during by the rotation of the direction of arrow A (press anticlockwise motion as depicted in figs. 1 and 2), the visco-elastic material that is contained in the pipe is extracted and pumps into the syringe 12 interior (direction of arrow B among Fig. 2) that is clamped on the syringe clamper by this pipe from be received in the supply container 14 in mouthfuls 18.
Owing to be contained in the viscosity (Fig. 2) of the visco-elastic material 22 in the supply container 14, the discrepancy in elevation H of liquid may be not enough to guarantee pump into above-mentioned that pipe 52 is poured into by visco-elastic material always in the operating process.This just may cause formation air filled cavity or bubble in pipe 52, and thus in the suction syringe 12, this is that people are undesirable.
In order to prevent this potential air admission problem, in device 10, preferably include and be used for enough pressure supply container 14 pressurizations so that guarantee in pipe 52, can not form the device 90 (Fig. 1) of air filled cavity or bubble in the perfusion operation of syringe.As shown in the figure, pressure device 90 comprises an air pump 92, and its mouth is connected on the adaptive device 96 that is in supply container 14 tops by air duct 94.Therefore, preferably visco-elastic material 22 is contained in one sterile, in crushable plastic bag or the soft shell 98, pollute visco-elastic material with the foreign body in the pressurized air that prevents to form by air pump 92.Also have a reducing valve 100 on supply container 14 tops, be used to prevent supply container overvoltage (Fig. 1 and Fig. 2).
The above-mentioned air pressurized to the visco-elastic material supply container is feasible for the appearance that prevents bubble when syringe is poured into, some the time or even essential.Yet, do not think at present, only by not using ram type pump 60 just can finish satisfactorily memory fluid from supply container 14 this task in transfer tube 52 is sent to syringe 12 to the supply container pressurization.This is necessary because the micro-manipulation of the flow of visco-elastic material is that visco-elastic material with predetermined close pours into little volume syringe.
Typically, battery socket 118 provides 110 volts of alternating current, and A/D converter 112 provides 12 volts of direct current (DC) through out-put supply line 124.The material transfer pump timer switch 128 of perfusion switch of often opening 126 and Chang Kai is parallel on the power lead 124 by electric wire 130 and 132 respectively, and two switches all are connected on the housing front panel 122.
Transfer pump timer switch 128 is variable time switch, and it is manually operable or put fixed (Fig. 1,2 and 5) by a rotating control piece 134 that is exposed to front panel outside.Timer switch 128 has and is attached thereto, preferably with the scale 136 of milliliter (ml) delineation.Scale 136 can be used as an expose portion of switch 28, (as shown in the figure), perhaps, is engraved on the housing front panel around switch control piece 124.The scale of scale 136 is corresponding to the visco-elastic material in the supply container 14 is filled into the needed pump work time in the syringe 12 that is clamped on the syringe clamper 30 with selected dosage.
When perfusion one of switch 126 or pump time switch 128 are closed, be transferred on the normal opened contact 140 of control relay 142 through parallel power lead 130 and 132a and public power lead 144 from the vdc of AC/DC changeover switch 112.When relay tip 140 closures (below will illustrate), and one of switch 126 and 128 closure and source switch 120 are when closed, direct-current control voltage is transferred on the electrical motor 62 of visco-elastic material transfer pump 60 through electronic circuit 146 from AC/DC changeover switch 112, and is sent on the air pump 92 through electronic circuit 148.
The contact 140 of control relay 142 is by 150 controls of normally closed sensor, this sensor is installed on the syringe clamper 30 or on the position in its vicinity, be used for being filled into predetermined perfusion level by transfer pump 60 when the syringe that is clamped on the syringe clamper, during preferably maximum groundwater increment (Fig. 2), this state-detection is come out, sensor 150 can be a kind of common position transduser, for example, light-emitting diode and corresponding photoemissive element or hall effect device, this sensor energize (being in the state of " ON ") reaches predetermined syringe groundwater increment up to.
Vdc is supplied with the side (when source switch 120 and one of perfusion switch 126 and pump time switch 128 are closed) of sensors 150 through power lead 152, and power lead 152 is connected to the upstream side (A side) of relay tip 140, sees Fig. 5.Therefore, as long as sensor 150 keeps normally closed, vdc is transferred to through lead 154 on the control coil 156 of relay 142 by sensor, thus, makes the relay tip closure and remains closed startup drive pump 60 and air pump 92 work.Operation
The operation of device 10 is fully aware of from top detailed description, yet, in order to make it clearer and, will to be briefly described method of operation below for on-the-spot method with visco-elastic material perfusion syringe is described.
Attaching plug 116 is inserted in the socket 118.Visco-elastic material supply container 14 and the pipe 52 that is connected to its bottom inserted admit mouthfuls 20, that unclamps supporting member 72 and pivot turns to its open position (Fig. 1 and 2) by being directed downwards of arrow B, partly being inserted in the middle of the pipe 52 between supporting member surface 80 and the pump head assembly 64, supporting member is rotated back into its make position and in place with locking piece 82 lockings in the opposite direction then.To manage afterwards 52 free end from the top of housing 16 screw out and screw in syringe clamper 30 below part and cut the sealed end (not shown).
Then source switch 120 is connected.Do not have all then to pour into switch 126 and to connect if manage 52, make the transfer pump 60 can be thus according to the required schedule time length work of this pipe of perfusion with the perfusion of the visco-elastic material in the supply container 14.For this pumping operation, pump head assembly 64 rotates by the direction of arrow A with pump motor 62, and thus, pump head roller 70 sequentially flattens pipe 52 parts that enter between pump head assembly and the supporting member 72, in such a way, forces visco-elastic material to pass through this pipe.By kind of a reperfusion mode, the extended period that pumps into operation by pump 60 is by the decision of opening circuit of the time delay of perfusion switch 126.
Should be noted that electric control structure according to Fig. 5, air pump 92 and transfer pump 60 synchronous operations, so that to the supply container pressurization and force visco-elastic material to flow out into pipe 52 from soft shell 98, thus, it can pump into by transfer pump 60.Be also to be noted that sensing switch 150 keeps " closure ", so that the contact 140 of relay 142 is also remained closed and primer pump 60 and 92 work.
When pipe 52 has poured into visco-elastic material by aforesaid mode, make source switch 120 get back to " OFF " position.Syringe 12 is inserted in the syringe clamper 30, the free end of managing 52 is contained on the syringe end 56, afterwards, syringe 12 is locked on the syringe clamper 30 by locking piece 40.Regulate pump time switch 128 up on disk 136, indicating desired syringe groundwater increment (Fig. 1 and Fig. 2) by part 134.Then source switch 120 is got back on the position of " ON ", and to transfer pump 60 power supplies, till timer switch 128 cuts off automatically.Under aforementioned tube perfusion operational circumstances, air pump 90 and 60 synchronous operations of liquid transfer pump are so that the perfusion of assist injection device operation.
When carrying out the syringe perfusion, sensing switch 150 will remain closed, and thus, start syringe perfusion operation.Yet, under improper situation.When the syringe groundwater increment that is preset by time switch 128 reached, transfer pump 60 can not be realized cutting off, and visco-elastic material will continue to pump into syringe 12.In this case, when reaching the predetermined maximum groundwater increment of syringe 12, switch 150 will disconnect, relay coil 156 then loses excitation, and relay 140 will disconnect, thus, cut off the power supply of liquid transfer pump 60 and air pump 90, syringe perfusion operation stops.
After syringe perfusion operation is finished, source switch is got back to " OFF " position, the syringe 12 that has poured into is unclamped and take off from syringe clamper 30.Suppose that supply container 14 and pipe 52 do not use up by the perfusion syringe, necessary maintenance system, particularly visco-elastic material is aseptic, and this germ-free condition can keep by being locked on the syringe clamper 30 on the free end that the empty syringe 12 of a sterilization is connected to pipe 52 and syringe.Another kind method is with a suitable disinfectant cup or stopper (not shown) the open end of pipe 52 to be sealed, so that make visco-elastic material keep germ-free condition.
By installing 10, syringe 12 can be easy to and pour on the spot soon visco-elastic material as stated above.
Although the apparatus and method of on-the-spot syringe perfusion have been described, especially for the apparatus and method of automatically pouring into common syringe with the visco-elastic material scene in the visoelasticity container, according to embodiments of the invention use advantage of the present invention has been described, but should be understood that and the invention is not restricted to this.Therefore, the those of ordinary skill of medical professionalism can be made any improvement or the conversion that is equal to, but everything all is considered to drop within the protection domain of appended claims.
