Abstract
The utility model discloses a crystal nucleus-breaking device for cataract operations, which comprises a handle, nucleus breaking heads, connecting members and a limiting element, wherein the handle is formed by two handle bodies, and one ends of the two handle bodies are mutually pressed, and the other ends thereof are respectively connected with a nucleus breaking head through the connecting members, the inner sides of two nucleus breaking heads are respectively and inwards provided with corresponding knife-edges, and the limiting elements are threaded through the two handle bodies of the handle. The crystal nucleus-breaking device for cataract operations overcomes the weakness of adopting two devices to finishing the operation, and can finish the operation by one device, which not only has simple structure, changes the double hand operation into single operation in use, and is easy to operate, can avoid enlarging wound and damaging other tissues in the operation, and is safe and reliable.
Description
Technical field
This utility model relates to a kind of operational tool, especially a kind of cataract operation instrument.
Background technology
At present, cataract is the highest ophthalmic diseases of China's blind rate, and along with the quickening of growth in the living standard and population aged aging speed, the quantity of senile cataract increases day by day, and diabetes complicated cataractous number also rises year by year.Have data to show, among the old people more than present 70 one full year of life, cataract incidence is up to more than 80%.Cataract accounts for 40.6% of blindness and low vision case, and operation is unique effective ways of treatment cataract disease.
At present, the main operation method of China's treatment cataract disease is to implant the cataract ultrasonic emulsification artificial intraocular lenses, it almost is the operation method of the unique use in developed regions that the cataract ultrasonic emulsification artificial intraocular lenses implants (PHACO+IOL) art, has advantages such as otch is little, operating time is short.But, phacoemulsification cataract extraction art apparatus expensive, the surgery cost height, operation easier is big.For the super newborn equipment of unable purchase or lack the basic hospital of senior operative doctor and be not suitable for.
The non-phacoemulsification cataract extraction of the little otch of no suture (ECCE+IOL) art, because of its operation method is easy to grasp, do not need special installation and apparatus, it is fast that Postoperative visual acuity is recovered, surgery cost is low, complication is few, and the patient is easy to accept, and can carry out at the basic hospital that does not have condition to carry out ultrasonic emulsification cataract.But the operational tool of not having the non-phacoemulsification cataract extraction of the little otch of suture (ECCE+IOL) art at present need adopt two apparatuses to finish jointly, in use exists certain inconvenience.
The utility model content
In view of this, it is simple in structure that main purpose of the present utility model is to provide, easy to operate and safe and reliable a kind of cataract operation crystal nucleus-crushing device.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of cataract operation crystal nucleus-crushing device, comprise handle, fragmentation nucleus head, connector and locating part, described handle is made up of two handle bodies, one end of two handle bodies offsets, the other end connects a fragmentation nucleus head by connector respectively, is equipped with the corresponding edge of a knife to convex respectively on the medial surface of two fragmentation nucleus heads, also is equipped with locating part on two handle bodies of handle.
Described handle is an arc, and an end that is connected with the fragmentation nucleus head sinks compared to the other end.
Described locating part is located on the end of the close fragmentation nucleus head on two handle bodies of handle.
Adopt the beneficial effect after the technique scheme to be: cataract operation crystal nucleus-crushing device of the present utility model, overcome existing the needs to adopt two shortcomings that apparatus is finished jointly, realize that an apparatus can finish operation.Not only simple in structure, and the change bimanualness is one-handed performance in using, easy to operate.In the operating process, can avoid enlarging wound in the operation and injuring other tissue, safe and reliable.
Description of drawings
Fig. 1 is the front view of this utility model cataract operation crystal nucleus-crushing device;
Fig. 2 is the vertical view of this utility model cataract operation crystal nucleus-crushing device;
Fig. 3 is the front view of this utility model cataract operation crystal nucleus-crushing device fragmentation nucleus head;
Fig. 4 is the vertical view of this utility model cataract operation crystal nucleus-crushing device fragmentation nucleus head.
Wherein, 1 handle, 2 fragmentation nucleus heads, 3 locating parts, 4 edges of a knife, 5 connectors.
The specific embodiment
As shown in Figure 1 and Figure 2, this utility model cataract operation crystal nucleus-crushing device comprises handle 1, fragmentation nucleus head 2, connector 5 and locating part 3, handle 1 is made up of two handle bodies, one end of two handle bodies offsets, the other end connects a fragmentation nucleus head 2 by connector 5 respectively, can peg graft by connector 5 between described handle 1 and the fragmentation nucleus head 2, also can realize fixed.Be equipped with the corresponding edge of a knife 4 to convex respectively on the medial surface of two fragmentation nucleus heads 2, the edge of a knife 4 can be arc or other arbitrary shapes, and the edge of a knife 4 mutual interlocks can be cut off tissue when closed.Also be equipped with locating part 3 on two handle bodies of handle 1, as shown in Figure 3, Figure 4.
As shown in Figure 1, described handle 1 is an arc, and an end that is connected with fragmentation nucleus head 2 sinks compared to the other end.The similar soupspoon of described nucleus-crushing device monnolithic case can prevent apparatus contact geisoma, handled easily during operation.
Locating part 3 is located on the end of the close fragmentation nucleus head 2 on two handle bodies of handle 1.Locating part 3 can be stop screw or adopts other known technologies, and locating part 3 can limit the open maximum angle of apparatus, prevents that opening angle is crossed the macrolesion surrounding tissue in the operation.
This utility model cataract operation crystal nucleus-crushing device can be made with rustless steel.In operation, utilize this utility model cataract operation crystal nucleus-crushing device to take out the nucleus lentis of pathological changes, not only overcome existing the needs to adopt two shortcomings that apparatus is finished jointly, realize that an apparatus can finish operation.And simple in structure, and the change bimanualness is one-handed performance in using, easy to operate.In the operating process, can avoid enlarging wound in the operation and injuring other tissue, safe and reliable.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
