Definitions
- the present invention relates to a capsular incision device, and more particularly, to a capsular capsular incision device capable of incising the front surface of the capsular bag surrounding the lens of the eye.
- the eye which composes the body, is an organ that secures the field of view by detecting the intensity and wavelength of light. It includes a colorless and transparent lens, an iris that has pigments to determine the color of the pupil and acts as a diaphragm to control the amount of light entering the eye, and a retina made of transparent nerve tissue that corresponds to the film of a camera.
- the crystalline lens constituting the eye corresponds to the lens of a camera, and just as the sharpness of a photograph deteriorates when the lens is dirty, if the crystalline lens is clouded, it does not pass light well into the eye, so the object looks blurry.
- a clouding of the lens due to various causes is called a cataract.
- the method of treating cataract is to incise the capsular bag that surrounds the lens, pulverize the lens located inside it using ultrasound, and then the pulverized lens.
- a method of removing the lens using ultrasound or the like and inserting an artificial lens to replace the removed lens is widely used.
- the sclera or cornea is incised with a width of about 2 to 3 mm using a diamond knife, etc., and an incision tool with a bent tip of a needle is inserted through the incision to scrape the entire surface of the capsular bag and remove it in a predetermined shape, Accordingly, a method is used in which the exposed lens is pulverized using ultrasonic waves, the pulverized lens is suctioned and discharged to the outside, and an artificial lens is inserted and fixed there instead.
- the incision of the capsular bag corresponds to an important process associated with the safety of cataract surgery, and the operator micro-incises the cornea, inserts an incision through the micro-incised gap, and scrapes the front surface of the capsular bag several times to expose the lens.
- a micro-incision in the cornea should be minimized for postoperative recovery and vision stabilization, and incisions requiring excessive incision cannot be used during actual surgery.
- the operator has to move the incision very carefully several times in order to incise the front surface of the capsular bag, so that the procedure is complicated and takes a long time. Therefore, when using an incision machine, it is difficult to cleanly and accurately incise the capsular bag in an appropriate size and shape, and radial rupture may occur if the capsular bag is not incised in an appropriate size and shape.
- the purpose of the present invention is to provide a capsular incision device that differentially applies power for capsular capsular incision to the capsular capsular incision according to the contact state of electrodes with respect to the capsular bag in order to solve the problems of the prior art as described above.
- the present invention provides a capsular incision device that differentially applies power for capsular incision to the capsular capsular incision according to the contact state of electrodes with respect to the capsular capsular capsular incision.
- power for capsular incision can be differentially applied to the capsular incision according to the contact state of the electrode with the capsular bag.
- the capsular bag can be quickly and accurately cut in a circular shape using heat or plasma generated by current or high-frequency power applied according to the contact state of the capsular bag.
