Description
Technical field
The present invention relates to a kind of ophthalmic operating set, specifically refer to a kind of discission needle.
Background technology
At present, in extracapsular cataract extraction operation, continuous capsulorhexis is one of committed step of cataract operation, and its success or failure are straight
Connect and affect surgical effect and patient health.Therefore, when art carries out continuous capsulorhexis, often by means of Tweezers for eye surgery.Surgical doctor is existing
Some operational approach are by the head-bent 1/4 week of No. 23 syringe needles, make the angle between needle point and needle slope about in 45 °, use
Syringe needle makees a puncture orifice in the nearly center of anterior lens capsule, cuts anterior capsule with the side edge arc of syringe needle, and span is expection
Capsulorhexis radius.From the lower section tearing leading edge, anterior capsule is lifted up, promotes then up, forward cyst membrane tearing port.Subsequently,
After forming sufficiently large cyst membrane lobe, overturn cyst membrane lobe so that it is epithelial surface is towards cornea, after forming cyst membrane lobe, by suitably
Control capsulorhexis direction with shape conglobate capsulorhexis mouth.
Wherein during capsulorhexis, the size of capsulorhexis mouth is not easy to control, and each surgical doctor operational capacity is different,
Also have the biggest difference in capsulorhexis mouth size, be even difficult to form circular capsulorhexis mouth；And affect use tradition discission needle and obtain
The factor of preferable capsulorhexis mouth is a lot, as cornea amplification can make capsulorhexis mouth seen by surgical doctor bigger than real；Pupil is big
The little impact on operation；Being asymmetrical in shape of capsulorhexis mouth can cause intraocular lens's off-center.Meanwhile, tradition discission needle is used
Intraoperative compliaction easily occur, anterior capsule tearing edge is discontinuous, and capsulorhexis mouth involves Suspensory ligament etc. problem to periphery tear.With
Time, surgical doctor need to be accumulated experience by longer learning cycle, could skillfully use traditional discission needle, especially for one
Some complicated cataract situations, as superhard or the softest in pediatric cataract, glaucoma, cataract, the patient of ciliary Zonular weakness
Deng, use traditional discission needle to tear curvilinear capsulorhexis continuously and can bring difficulty, be easily caused other operative complications.
Summary of the invention
It is an object of the invention to: a kind of discission needle is provided, solve surgical doctor and rely on experience to carry out capsulorhexis operation, capsulorhexis
Process is not easy to control capsulorhexis mouth size and causes the problems such as capsulorhexis success rate is low.The present invention is by arranging the first gear and the second tooth
Wheel, by rotating the rotation bar on the second gear, the second gear and the engagement of the first gear, and then drive the first gear simultaneously, set
Put needle body on the first gear to rotate, needle body lower end draw that film is most advanced and sophisticated will scratch capsule before cataract according to predetermined radius of circle
Film, carries out capsulorhexis, and whole operating process is avoided empirically operating, and capsulorhexis mouth-shaped is symmetrical, the flush edge torn, and improves
The success rate of operation, and it is easy to surgical doctor operation.
The present invention is achieved through the following technical solutions: a kind of discission needle, including rotating bar, the first gear and the first gear
Second gear of engagement, the first gear includes disc base, the gear teeth being arranged on disc base upper surface, runs through in disc base
