Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to ultrasonic energy in a kind of cataract surgery automatic control system as required.
Background technology
Cataract is common blinding oculopathy.Cataract surgery (Phaco), by introducing China last century, has been cataractous conventional treatments now.For the traditional whole excision of large otch cataract operation, phacoemulsification (Phaco) is a kind of Minimally Invasive Surgery, on cornea limit, to output a little otch of 2-3 millimeter, via this little incision, stretching into ultrasonic emulsification syringe needle smashes muddy crystalline lens and cortex into after chyle shape, by aspirating filling system by the sucking-off of chyle shape thing, keep anterior chamber full, then implantable artificial crystal, sees light again patient simultaneously.Compare with traditional pioneering operation, cataract surgery belongs to Minimally Invasive Surgery, has the advantages such as recovery time that otch is little, post-operative complication is few and shortened patient; Meanwhile, also reduce the demand of operation to vacuum, shortened operating time, also therefore improved safety.
But too much ultrasonic energy causes certain damage also can to eyes, particularly endothelial cell.Therefore, reduce as far as possible other position that ultrasonic energy is radiated the eye-chamber, bring very large benefit will to doctor and patient.At present, on market, mainly contain two kinds of basic supersonic vibration patterns.Two kinds of basic supersonic vibration patterns are respectively: longitudinal vibration pattern and the horizontal pattern of shaking, add crooked mode by torsion and cause.The shortcoming of longitudinal vibration is: longitudinal vibration meeting causes that vibrational energy repulsion cataract is away from emulsifying syringe needle, considerably hinders fluid and the suction mobility of organizing fragment.So doctor needs to use ultrasonic emulsification syringe needle to catch up with cataract tissue fragment sometimes, or push cataract tissue with another one operation tool.Horizontal shortcoming of shaking is: there is the supersonic vibration of suitable intensity ultrasonic emulsification syringe needle side.Yet cataract itself is due to the effect of vacuum draw, mainly be adsorbed on the positive front end face of ultrasonic emulsification syringe needle, so have the ultrasonic energy of quite a few to have no to stop to be applied in the eye-chamber, cornea inner surface, even on iris, can cause the injury to it, and the crushing function of cataract itself has been reduced.
The accurate control doctor of ultrasonic emulsification energy improves emulsifying skill, reduces the major issue that postoperative complication faces.Therefore, the control about ultrasonic emulsification energy is one of important indicator of weighing ultrasonic emulsification instrument function with discharging.From ultrasonic emulsification technology, come out to being developed so far, from instrument aspect, the control experience development of ultrasonic emulsification energy is mainly contained to 3 stages: the first stage: continuous and continuous lines sexual norm, its key character is: on the basis of 100% horizontal ultrasonic energy, and the foot-operated output amplitude of controlling energy.Second stage: imitate the gear changing by foot of patient when using Continuous Energy pattern by instrument reform and operate, take pulse mode and burst mode as representative.Phase III: coordinate " cold phaco " (cold phaco) of micro-incision technology, micropulse, micro-explosion pattern that pattern occurs, be mainly represented as: White Star cataract surgery system.For traditional continous way, pulsed, explosion type, micropulse, micro-explosion pattern, wherein pulsed and explosion type can be can be regarded as pattern of the same race in ultimate principle, major function is to add the gap stopping in original continuous ultrasonication, makes the organizer that should be washed away by continuous ultrasound stream or fragment and is adsorbed back Phacoemulsification needle end surface.This control model, compared with continous way pattern, has increased the mobility of suction to a certain extent, has also increased the order of contact of tissue and Phacoemulsification needle end surface, thereby has relatively reduced the waste of ultrasonic energy.But this pattern is with randomness, and the still unavoidable waste of energy and the reduction of efficiency, especially to crossing cataract tissue soft or really up to the mark.
Therefore be necessary to propose a kind of new technical scheme, to solve the waste of too much ultrasonic energy, the above-mentioned technical problem even eye inner tissue being damaged, acts on cataract tissue optimal ultrasonic energy safely.

Shown in accompanying drawing 1, the energy management system in a kind of cataract surgery that this utility model discloses, comprising: ultrasonic emulsification handle 1 and be coupled in the ultrasonic emulsification syringe needle 2 of its far-end; Described ultrasonic emulsification handle 1 is connected to ultrasonic electric generator 5 by ultrasonic-frequency power supply line 11, and the electroacoustic converting unit in described ultrasonic emulsification handle 1 changes the signal of telecommunication being sent by ultrasonic electric generator 5 receiving into supersonic frequency mechanical vibration;
One device for vacuum generation 7, one side is connected to described ultrasonic emulsification handle 1 by suction channel 8, and opposite side is connected to a waste fluid bag 9 by suction channel.In this first embodiment, on described suction channel 8, be connected with a controller 6, and between described vacuum generating device 7 and described ultrasonic emulsification handle 1.Described controller 6 is connected in described ultrasonic electric generator 5 by holding wire 10, to institute's ultrasonic electric generator 5, is electrical control.
Described controller 6 specifically mainly comprises sensor, comparator and control unit.Described sensor is pressure transducer or flow sensor, is located on suction channel and for the pressure in suction channel described in perception or flow velocity.The default pressure of normal surgical state or the standard value X of flow velocity in described comparator, the pressure in the operation process that can obtain with described sensor or the measured value Y of flow velocity compare., to ultrasonic electric, there are 5 devices and send instruction in the result after control unit receives relatively, control described ultrasonic electric generator ultrasonic energy output unlatching or close, strengthen or reduce.
Below in conjunction with preferred implementation of the present utility model, the energy control method that the work process of the energy management system in phacoemulsification described in the utility model and this utility model are disclosed is further detailed.
Common cataract ultrasonic emulsification instrument is comprised of main frame and ultrasonic emulsification handle 1 etc., and the far-end of ultrasonic emulsification handle 1 is coupled with ultrasonic emulsification syringe needle 2.Ultrasonic electric generator 5 is exported the supersonic frequency signals of telecommunication to handle 1 by ultrasonic-frequency power supply line 11, electroacoustic converting unit in described ultrasonic emulsification handle 1 changes the signal of telecommunication being sent by ultrasonic electric generator 5 receiving into supersonic frequency mechanical vibration, and its ultrasonic energy passes on the ultrasonic emulsification syringe needle 2 of coupling by ultrasonic emulsification handle 1.
When performing the operation, start energy management system.Along with the beginning of operation, ultrasonic emulsification syringe needle 2, under the effect of ultrasonic emulsification handle 1, acts on the cataract tissue 4 of eye-chamber pouch 3, makes cataract tissue 4 emulsifyings, fragmentation, loosening.When vacuum generator 7 is adsorbed onto syringe needle front end face by the cataract tissue in eye-chamber pouch 34, the fragment of the emulsifying due to supersonic vibration, fragmentation, loosening cataract tissue 4, by sucking-off glibly, arrives 9 li of waste fluid bags via suction channel 8.
Along with emulsified, broken, loosening cataract tissue 4 is along the flowing of the liquid of 8 li of described suction channels, the pressure that suction channel is 8 li is also changing, and meanwhile, the flow velocity of the liquid that suction channel is 8 li also changes occurring.
When emulsifying, fragmentation, loosening cataract tissue 4 are during by sucking-off glibly, the pressure in suction channel 8 is little, and the flow velocity of liquid is large; Now, do not need ultrasonic vibrational energy to the cataract tissue effect in eye-chamber pouch 3; When cataract tissue is firmly to a certain extent time, in the time of can not sucking from the far-end of ultrasonic emulsification syringe needle 2, to stopping up from ultrasonic emulsification syringe needle 2 on the contrary, now, vacuum in suction channel 8 raises, and the flow velocity of liquid also diminishes, so need the cataract tissue of enough energy in eye-chamber pouch 3, just can make its emulsifying, fragmentation, loosening, operation is just proceeded.
Therefore, we can, according to cataractous soft or hard state or degree of crushing in operation process, carry out automatically to control at any time the unlatching of ultrasonic energy output or close, strengthen or reduce.Control method of the present utility model, comprises the steps:
Steps A: pressure or flow speed value while presetting normal operation in comparator are standard value X;
Step B: sensor obtains pressure in operation process or the measured value Y of flow velocity;
Step C: described comparator compares measured value Y and default standard value X;
Step D:
D1, when sensor is pressure transducer, when pressure measured value Y is less than pressure criteria value X, control unit sends instruction to ultrasonic electric generator, controls the energy of ultrasonic electric generator output and closes or be reduced to default output W1; Or when sensor is flow sensor, when flow velocity measured value Y is greater than flow velocity standard value X, control unit sends instruction to ultrasonic electric generator, control the energy of ultrasonic electric generator output and close or be reduced to default output W1;
D2, when sensor is pressure transducer, when pressure measured value Y is greater than pressure criteria value X, control unit sends instruction to ultrasonic electric generator, controls the energy of ultrasonic electric generator output and opens or be enhanced to default output W2; Or when sensor is flow sensor, when flow velocity measured value Y is less than flow velocity standard value X, control unit sends instruction to ultrasonic electric generator, control the energy of ultrasonic electric generator output and open or be enhanced to default output W2;
Step e: press millisecond meter, repeating step B, step C, step D, until performed the operation or manually stopped.
In above-mentioned steps D, reduce or be enhanced to the adjustment process of default output, can be ladder adjusting and also can be linear regulation.Be specially: when ultrasonic emulsification syringe needle 2 stops up, sensor will sense the rising of vacuum pressure or the reduction of the interior flow velocity of suction channel, as pressure measured value Y> threshold pressure value X, or flow velocity measured value < threshold flow rate value X, just open (if the words of closing in advance) or strengthen (if in advance lower words) ultrasonic power output, its power is changed into ladder and is regulated and also can be linear regulation.
When cataract tissue 4 is broken, when emulsifying, loosening and sucking-off, sensor also can sense the reduction of vacuum pressure or the increase of the interior flow velocity of suction channel, as pressure measured value Y< threshold pressure value X, or flow velocity measured value Y> threshold flow rate value X, just close or reduce the output of ultrasonic power, its power changes too for ladder adjusting also can be linear regulation.
In the situation that some is special, in the time of cannot be lower than predefined threshold value when as really up to the mark in cataract or other obstacles cause measurement of inductance value long, if a ultrasonic direct-open may cause the heat of ultrasonic generation to be trapped in the eye-chamber or incision and cause surgical injury, so be necessary to add a timing controlled this under higher than the state of threshold value in the work process of ultrasonic electric generator 5, be conventionally less than 2 seconds.Therefore in this utility model, also comprise time control step in described step D, when strengthening or reduce output, continue to after the Preset Time (being made as 2 seconds) of the time relay, control unit can reduce or close ultrasonic electric generator by force.On the contrary, if lower than the state of threshold value, illustrate that this situation does not need high-intensity ultrasonic or do not need ultrasonicly when measurement of inductance value is long, also just there is no need improve or open ultrasonic, thereby reduced to greatest extent ultrasonic consumption, this is also a usefulness of the present utility model.
In operation process, sensor detects suction channel 8 internal pressures or flow velocity in real time by millisecond meter, comparator is also being judged under the conclusion of standard of comparison value and measured value in real time, ultrasonic electric generator 5 is the output of repeatedly opening or cutting out, strengthening or reducing ultrasonic energy as above under the order of control unit, until complete operation process or manually stop.
So by the blockage of syringe needle, automatically open or close ultrasonic, make ultrasonic energy most effectively minimally act in cataract, thereby effectively reduced the repulsive force to tissue causing due to hypersonic flow and improved mobile followability, also farthest improved the utilization rate of ultrasonic energy, reduce side effect, improved safety.

When vacuum is adsorbed onto syringe needle front end face by the cataract tissue in eye-chamber pouch 34, the emulsifying due to supersonic vibration, fragmentation, loosening by fragment and the sucking-off in the lump of eye-chamber liquid, arrive 9 li of waste fluid bags via suction channel 8.Liquid filling bottle 90 by liquid injecting pipeline 80 by liquid as normal saline injects in the eye-chamber 3, maintain the eye-chamber 3 and press equilibrium of forces, avoid the eye-chamber 3 subsiding because of the sucking-off of liquid.And in the present embodiment, the sensor of controller 6,60 is all installed on suction channel 8 and liquid injecting pipeline 80, the sensor of controller 60 can certainly be only installed on liquid injecting pipeline 80, or the sensor of controller 6 is only installed as the first embodiment on suction channel 8, as pressure or flow sensor.
When only controller 60 being installed on liquid injecting pipeline 80, the work process of this controller 60 is similar to the work process of the controller 6 of the first embodiment, unique difference is: that this controller 60 obtains is the pressure of liquid injecting pipeline 80 or the measured value Y of flow velocity, when the reduction of sensor sensing to flow velocity in the rising of vacuum pressure or suction channel, when sensor sensing is during to the reduction of flow velocity in the rising of vacuum pressure or suction channel, as pressure measured value Y> threshold pressure value X, or flow velocity measured value < threshold flow rate value X, just open (if the words of closing in advance) or strengthen (if in advance lower words) ultrasonic power output, its power is changed into ladder adjusting and also be can be linear regulation.When cataract tissue 4 is broken, when emulsifying, loosening and sucking-off, sensor also can sense the reduction of vacuum pressure or the increase of the interior flow velocity of suction channel, as pressure measured value Y< threshold pressure value X, or flow velocity measured value Y> threshold flow rate value X, just close or reduce the output of ultrasonic power, its power changes too for ladder adjusting also can be linear regulation.
When the sensor of controller 6,60 being all installed on suction channel 8 and liquid injecting pipeline 80, as long as one of them controller 6,60 reaches after the condition that changes ultrasonic power, driving ultrasonic electric generator 5 switches or change ultrasonic power.
In this utility model, utilize simple pressure or flow threshold, a definite value just, triggers the switch of ultrasonic generation, or the increase of ultrasonic energy, reduction, realizes simple and convenient.In addition, do not need to adopt the pulse technique of prior art yet, and as long as simple ladder regulates or linear regulation ultrasonic energy, reliably effective.In addition, the timing mode providing, control unit can reduce or close ultrasonic electric generator by force, can utilize most effectively ultrasonic energy; Reduce to greatest extent ultrasonic energy, even do not use; Avoid wound to burn; Reduce the damage ratio of endotheliocyte.
