Description
Technical field
The present invention relates to ophthalmic medical instrument, especially relate to a kind of Multifunctional cataract surgical hook.
Background technology
In existing cataract eye surgery, leak owing to often there is otch, therefore easily cause complication.
The remarkable minimizing of incision of cataract reduction and related complication is the spotlight in cataract operation development history, also be the direction of ophthalmologist's long-term endeavour, in ophthalmologic operation work, especially in small notch, Appropriate application reverse headgear and otch leak, and can simplify operating procedure, reduce postoperative complication.Chinese patent CN201094694 discloses a kind of perfusion extruding pressing fragmentation nucleus knife for the treatment of cataract, handle connects hollow fragmentation nucleus cutter head, the end of hollow fragmentation nucleus cutter head sets out water hole and dials core head, and this utility model has the effect that can realize Microphacoemulsification operation.
Summary of the invention
The object of the invention is to in existing cataract eye surgery due to apparatus turnover otch time, easily cause otch seepage, the anterior chamber that is in a tumult, cause the problems such as complication, a kind of Multifunctional cataract surgical hook is provided.
The present invention is provided with the hollow coupler body of L shape, connecting portion and hollow handle, the front end of the horizontal component of the hollow coupler body of described L shape is provided with downward bent part, the end of downward bent part is spheroid, the vertical component of the hollow coupler body of described L shape is reverse taper, downward bent part above spheroid is provided with upper water-out hole and lower apopore, the upper end of reverse taper is connected with connecting portion, and connecting portion is connected with hollow handle and medical infusion lines respectively.
The length of described horizontal component can be 10 ~ 30mm, and the external diameter of horizontal component can be 0.5 ~ 1.2mm; The length of described downward bent part can be 1 ~ 8mm, and the external diameter of downward bent part can be 0.3 ~ 1mm; The diameter of described spheroid is less than 1mm; The aperture of described upper water-out hole and lower apopore can be 0.2 ~ 0.9mm; The length of described reverse taper can be 20 ~ 50mm, and the external diameter of reverse taper can be 1.3 ~ 10mm.
Described upper water-out hole and lower apopore are preferably located on the same side of the downward bent part above spheroid.
Outstanding advantages of the present invention is:
1) construction features of the present invention is provided with hollow coupler body in lower end, overall in streamlined, not only be beneficial to the smooth outflow of current, and not easy damaged otch and eye inner tissue, hollow coupler body upper end coincide and connects hospital's transfusion organ pipe end, the horizontal component end of hollow coupler body is spherical shape, proximal end is provided with two apopores, two current can bump against the spray and eddy current that produce without destructive power within the eye, be beneficial to water outlet, water flows into anterior chamber in eyeball, can deliberately form otch where necessary to leak, be of value to quicker but also safer the completing of operation, otch keeps anterior chamber to stablize when leaking, and safety complete operation.
2) the present invention is as ophthalmology micro-surgical instrument, can be used for the water separation of the non-ultrasonic maneuver cataractopiesis of minimal incision *, water stratification, dialled that core goes out core, auxiliary pyrene fragmentation nucleus, rinses cortex, the operating procedure such as rear capsule polishing and positioning artificial intraocular lenses, operation whole process can be made completing above operating procedure while to keep anterior chamber to stablize, reduce anterior chamber and be in a tumult and corresponding complication.Also be that the present invention is with dialling the multiple appliance function such as core device (L shape hook), crystal positioning hook, rear capsule polisher, anterior chamber regulator (reverse headgear pipe) and core splitting hook than the important breakthrough of existing ophthalmology micro-surgical instrument.
3) bulk flow Alignment Design of the present invention, structure is simple, has both facilitated smooth water outlet, is easy to again turnover cornea miniature incision.Use a kind of existing reverse headgear function to have again the apparatus of auxiliary hook function, existing structure simply easily passes in and out again the apparatus of miniature incision simultaneously, can avoid or alleviate the loss of cornea, pouch and iris, and protection Lens capsular, obtains challenging result.
4) described hollow coupler body can make by national standard is unified, make it can seamless link, the material of sufficient intensity and hardness must be used, such as steel alloy etc., make hollow coupler body requirement smooth surface, the enough one-time infusion tubes of handle inflated diameter pass through, and there is texture on surface, can help patient and hold tightly anti-skidding.
5) as large-scale production, reasonable employment modern industrial technology, can reduce costs, even use as medical disposable material, cataract surgery postoperative infection will be greatly reduced, stop Chao Ru collective scale cataract surgery postoperative infection (because super newborn syringe needle and pipeline are not correctly disposed and Reusability, the domestic serious accident just having infection in the postoperative ball of a lot of collectives cataract patient reported).
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
See Fig. 1, the embodiment of the present invention is provided with the hollow coupler body of L shape, connecting portion 2 and hollow handle 3, the front end of the horizontal component 11 of the hollow coupler body of described L shape is provided with downward bent part 110, the end of downward bent part 110 is spheroid 111, the vertical component of the hollow coupler body of described L shape is reverse taper 12, the same side of the downward bent part above spheroid 111 is provided with upper water-out hole 112 and lower apopore 113, the upper end of reverse taper 12 is connected with connecting portion 2, and connecting portion 2 is connected with hollow handle 3 and medical infusion lines respectively.
The length of described horizontal component 11 is 25mm, and the external diameter of horizontal component 11 is 1mm; The length of described downward bent part 110 is 6mm, and the external diameter of downward bent part 110 is 0.6mm; The diameter of described spheroid 111 is less than 1mm; The aperture of described upper water-out hole 112 and lower apopore 113 is 0.5mm; The length of described reverse taper 12 is 30mm, and the external diameter of reverse taper 12 is 1.3 ~ 10mm;
Below provide using method of the present invention:
Balance liquid bottle high for 0.3 ~ 2m is connected connecting portion 2 of the present invention by tube for transfusion, open tube for transfusion switch, the present invention can bring into use, the downward bent part 110 of hollow coupler body horizontal component 11 is entered anterior chamber by auxiliary cornea auxiliary incision or the main otch in corneosclera tunnel, current flow into ophthalmic by the upper water-out hole 112 on spheroid 111 and lower apopore 113, two strands of current can penetrate in 10mm collides, lose former directive impulsive force (destructive power brought to eliminate high-velocity flow with this), and produce spray even eddy current, so also contribute to the effect of aquation cataract crystal nuclear, water with stylish injection produces pressure and can offset otch fugitive water and reduce intraocular pressure, and reach a kind of new pressure balance, keep the pressure that the omnidistance camera oculi anterior of operation is enough, on this basis, the present invention completes multiple operation link, as water is separated, water stratification, dial core and go out core, auxiliary pyrene fragmentation nucleus, rinse cortex, the operating procedures such as rear capsule polishing (operating difficulty is larger) and positioning artificial intraocular lenses, do not elaborate at this.
