Abstract
The utility model provides a remover for cataract crystal nuclei, which is used for ophthalmology medical treatment. The remover for cataract crystal nuclei is composed of a handle and a suction disc which is fixedly connected to the front end. The utility model is characterized in that the inner side of the suction disc is concave or a spoon-shaped body, a suction channel and a liquid injection channel are arranged along the inner axial direction, a rear interface is communicated with a joint which is arranged on the handle, a suction opening and a liquid injection opening at the front end are respectively arranged on the inner side and the outer side of the suction disc, and the inner front side of the connecting point of the suction disc and the handle is provided with a movable valvula or a flexible valvula. The remover for cataract crystal nuclei has the advantages of simple structure, convenient operation, broad application range and easy popularization.
Description
This utility model relates to cataract crystal nuclear that a kind of ophthalmic medical the uses device of giving birth to.
At present, domestic the extracapsular cataract extraction intraocular lens implants is mainly adopted two kinds of modus operandis: 1, the big otch crystal nuclear of giving birth to, otch is about 8-9mm, and its major defect is that postoperative easily produces astigmatism; 2, the little otch crystal nuclear of giving birth to comprises that supersound method and hundred relies the krimer operation methods, and major defect is: ultraemulsifier costs an arm and a leg, and very poor to hardened crystal nuclear emulsifying effectiveness; Hundred rely the operating process of krimer operation very complicated, and technical difficulty is big, and easily cause posterior lens capsule film rupture and damage corneal endothelium.
The purpose of this utility model is a kind of cataract crystal nuclear that big small incision surgery the uses device of giving birth to that is fit to that designs for the shortcoming that overcomes above-mentioned prior art.
For achieving the above object, the technical solution of the utility model is: the sucker that the medical device of this ophthalmology is fixedlyed connected with front end by handle constitutes.Be characterized in that chuck surface is smooth, medial surface is recessed or become spoon shape body, is axially arranged with suction road and fluid injection road in handle.The rear port in suction road and fluid injection road is communicated with joint on the handle respectively, and the pump orifice of its front end and liquid injection port are opened respectively on the interior outside of sucker.
Be provided with a movable valve or a flexible valve in the inboard of sucker and handle junction.When advancing in the operation process, valve outwards opens automatically because of liquid resistance, when extracting out backward, and inside pressured crystal nuclear under liquid resistance and swabbing action.
Above-mentioned handle is column or inclined to one side shape body.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1: axonometric chart of the present utility model
Fig. 2: axonometric chart of the present utility model
Fig. 3: internal structure view of the present utility model.
Below in conjunction with embodiment (accompanying drawing) this utility model is further described:
As shown in Figure 1-Figure 3, the front end of handle 2 is the spoon shape suckers 7 of fixedlying connected with it, and inside is axially arranged with suction road 3 and fluid injection road 4.The rear end in suction road 3 and fluid injection road 4 respectively with handle on joint 1 connect, the pump orifice 6 of its front end and liquid injection port 8 are opened respectively on the interior outside of sucker 7.Valve 5 is in the inboard, junction of sucker 7 and handle 2.When hands was stated, joint 1 joined with aspirator and impregnator respectively.
The utility model compared with prior art has simple in structure, and is easy to operate and to adopting big or small type of incision The equal advantage applicatory of underdone phase, maturity period and hypermature cataract ECCE.
Claims (2)
1, a kind of cataract crystal nuclear device of giving birth to, the sucker of being fixedlyed connected with front end by handle constitutes, it is characterized in that the sucker inboard is recessed or be a spoon shape body, be axially arranged with suction road and fluid injection road in the handle, thereafter port communicates with joint on the handle respectively, and front end pump orifice and liquid injection port are respectively in sucker on the outside.
2, the cataract crystal nuclear as claimed in claim 1 device of giving birth to is characterized in that the front side is provided with movable valve or flexible cephacoria in sucker and handle junction.
