Intelligent ophthalmic ultrasonic emulsification apparatus

Abstract

The invention relates to an intelligent ophthalmic ultrasonic emulsification apparatus, comprising a host machine of a surgical apparatus, an ultrasonic emulsification handle, an image collection system and a foot brake, wherein the host machine of the surgical apparatus comprises a signal generator, a surgical process and affected-part state identification system, a negative-pressure flow control system, an energy control system and a touch / display device; the ultrasonic emulsification handle is provided with a power supply at the end, and the interior is connected with an amplitude transformer, the front end of the amplitude transformer is connected with an ultrasonic emulsification pinhead and is provided with a transducer inside and a silica gel sleeve outside, an injection and absorption pipe passes from the inside of the handle; the ultrasonic emulsification handle is provided with three keys including an optical identification key, a loading identification key and an energy control key; the image collection system includes an electron microscope for an eye surgery, an image collection card and a microcomputer special for the image treatment; the surgical process and affected-part state identification system includes a special handle with an identification key, a hardware software module for the collection, analysis and treatment of the handle ultrasonic signals; the ultrasonic emulsification pinhead is titanium alloy and is formed by different inclined planes and is detachable, the emulsificated crystal fragments are sucked out from a hollow pipe.

Description

technical field [0001] The invention is an ultrasonic surgical instrument for ophthalmic cataract treatment, and relates to an intelligent ophthalmic phacoemulsification equipment. Background technique [0002] The number of cataract cases in our country is increasing year by year. The disease not only causes psychological pain to the patients, but also becomes a serious burden to the society. So far, phacoemulsification combined with intraocular lens implantation is the most effective treatment for cataract. [0003] Cataract phacoemulsification is a surgical method that uses mechanical acceleration generated by ultrasonic vibration, acoustic microfluidics, and cavitation to break up cataract hard core tissue, emulsify it, and remove it through negative pressure. This technique is an advanced technique in intraocular lens implantation. It has the advantages of small surgical incision, short healing time, fast recovery of postoperative visual function and small corneal asti...

Problems solved by technology

However, the existing phacoemulsification apparatus has the following disadvantages: First, during the operation, the doctor needs to judge and monitor the hardness of the inner core and its emulsification process and state through a microscope, which increases the work intensity of the doctor and affects the effect and quality of the operation Secondly, when the inner core is sucked out, the high negative pressure inside the eyeball will cause the ball to sag, which may cause medical accidents such as posterior capsule tearing; thirdly, the doctor must control the output of ultrasonic energy by changing the angle of the foot switch to operate inconvenient
