The ultrasonic emulsification instrument auxiliary device which is connected between an ultrasonic emulsification instrument main machine and an original foot switch comprises an input interface, an auxiliary foot switch, a signal recorder, a signal generator and an output interface. Furthermore, a status signal which can be filled openly can record non-ultrasonic emulsification energy generated when the original foot switch is raised up in the signal recorder without any vacuum suction. In a cataract ultrasonic emulsification operation, an operational assistant can directly control the energy supply through controlling the auxiliary foot switch in the auxiliary device, thereby avoiding the operational accident.
Description
Technical field
The present invention relates to a kind of auxiliary device of medical apparatus and instruments, the auxiliary device of specifically a kind of ultrasonic emulsification instrument (phaco emulsificationmachine) makes the assistant can directly control ultrasonic emulsification energy and vacuum suction in the operation process.
Background technology
The ultrasonic emulsification operation is cataractous conventional treatments.Wherein the ultrasonic emulsification part is mainly independently finished by patient one people.In the ultrasonic emulsification operation technique of routine, the patient gives and vacuum suction by perfusion state, the ultrasonic emulsification energy of foot switch control ultrasonic emulsification treatment syringe needle, thus the carrying out of control operation.When foot switch was stepped on, open perfusion, generation ultrasonic emulsification energy and vacuum suction when foot switch lifts once more, still kept open dabbling state, and ultrasonic emulsification energy and vacuum suction simultaneously weakens gradually to closing.In operation process,, can cause multiple operations accidents such as the back capsule breaks, vitreous body outflow if treatment syringe needle energy when the posterior lens capsule is excessive or give incorrectly.Experienced surgical doctor often can be predicted the generation of dangerous situation, reduces in advance or stops ultrasonic emulsification energy and vacuum suction, thereby avoid performing the operation unexpected the generation.But the abecedarian and the person of being lacking in experience then lack this ability, therefore the unexpected probability of operation takes place want high a lot.Though experienced surgical doctor can be taken on the assistant, in operation process, give the abecedarian and the person of being lacking in experience prompting, but the response time that super breast conserving surgery needs is many within 0.1 second, only relies on assistant's voice suggestion often to be difficult to stop unexpected generation.Also do not have in the prior art and can give to avoid performing the operation unexpected equipment and the device that takes place by the energy that the assistant directly controls in the ultrasonic emulsification operation.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art, a kind of auxiliary device of ultrasonic emulsification instrument is provided, can make the assistant directly control the ultrasonic emulsification instrument main frame, in time stop ultrasonic emulsification energy and vacuum suction, take place unexpectedly thereby directly help surgical doctor better to avoid performing the operation.
This ultrasonic emulsification instrument auxiliary device is connected between ultrasonic emulsification instrument main frame and the former foot switch of ultrasonic emulsification instrument, comprises input interface, secondary foot switch, signal recorder, signal generator and output interface.Wherein input interface is connected on the former foot switch of ultrasonic emulsification instrument; Output interface is connected on the ultrasonic emulsification instrument main frame; Secondary foot switch is controlled by the assistant, is different from the former foot switch of operating doctor control; Signal recorder notes in advance that former foot switch is in open perfusion but signal when not having the particular state of ultrasonic emulsification energy, no vacuum suction, is defined as 0 status signal; And produce corresponding signal by signal generator.
In the custom operation of ultrasonic emulsification operation, be the state of no ultrasonic emulsification energy, no vacuum suction when foot switch lifts fully during operation, then the state that vacuum suction is arranged, the ultrasonic emulsification energy is arranged when foot switch is stepped on.For adapting to the operating habit of original ultrasonic emulsification operation, it is the state of no ultrasonic emulsification energy, no vacuum suction that the present invention is set at secondary foot switch when lifting fully too, and secondary foot switch is the state that vacuum suction is arranged, the ultrasonic emulsification energy is arranged when stepping on.
When secondary foot switch lifts, control system of the present invention starts, cut off the signal input of the former foot switch of ultrasonic emulsification instrument, and produce the no ultrasonic emulsification energy of having stored, no vacuum suction, also open dabbling 0 status signal, replace original former foot switch signal to input to the ultrasonic emulsification instrument main frame.This moment, ultrasonic emulsification instrument was in the state that breaks away from former foot switch control, did not have ultrasonic emulsification energy and vacuum suction to produce, and can suspend the operation risky operation and keep operative space stable.
When secondary foot switch was operated, control system of the present invention was closed, and control is given back former foot switch, made operation be able to proceed under the control of operating doctor.
Simulated the normal operating conditions when the former foot switch of ultrasonic emulsification instrument lifts in the signal recorder of system of the present invention in advance, promptly open the state of perfusion, no ultrasonic emulsification energy, no vacuum suction, therefore the present invention is helping surgical doctor to avoid performing the operation simultaneously unexpected, can't cause the system mistake of ultrasonic emulsification instrument, do not cause ultrasonic emulsification instrument self check again, keep its normal operating conditions, do not influenced operation process.
Description of drawings
Fig. 1 has ultrasonic emulsification instrument work sketch map now, and its foot-operated control is control ultrasonic emulsification instrument main frame directly.
When secondary foot switch was stepped among Fig. 2 the present invention, the work sketch map of ultrasonic emulsification instrument was still by former foot switch control ultrasonic emulsification instrument main frame.
When secondary foot switch lifted among Fig. 3 the present invention, the work sketch map of ultrasonic emulsification instrument, ultrasonic emulsification instrument broke away from former foot switch control.
The specific embodiment
Embodiment:
Show as Fig. 2, the attachment device of ultrasonic emulsification instrument is made up of input interface, secondary foot switch, signal recorder, signal generator and output interface, and has write down the no ultrasonic emulsification energy of ultrasonic emulsification instrument, no vacuum suction and open dabbling 0 attitude signal in signal generator in advance.Wherein secondary foot switch is by assistant's (the experience doctor is arranged) control, and former foot switch is by patient (new doctor) control.Under normal circumstances, the assistant steps on secondary foot switch, and monitors operation process.Then by former foot switch control ultrasonic emulsification instrument, the patient undergos surgery operation.When assistant's unusual circumstance, lift secondary foot switch, make signal generator produce the no ultrasonic emulsification energy of recording storage, no vacuum suction and open dabbling 0 status signal in signal recorder in advance, as shown in Figure 3, thereby make ultrasonic emulsification instrument break away from former foot switch control, suspend the operation risky operation and keep operative space stable.
