Description
Technical field
This utility model relates to medical instruments field, and a kind of novel cataract operation cutter specifically is provided.
Background technology
The otch of cataract operation is very important in whole cataract operation, is related to the success or failure of whole surgery.Operative incision by former corneoscleral junction otch, develops into present scleral tunnel otch and transparency cornea otch along with very big variation has also taken place improving constantly of operating technology.Various otch all have pluses and minuses separately, but the cutter performance demands is also all being improved constantly.Sharp cutter can make notching edge neat, and the operation corneal astigmatism following number of degrees are little, recovers fast.The cataract operation cutter of clinical practice at present is single cutter, finishes otch sometimes and need use two or more cutters, can cause frequently changing cutter, complex operation, deficiencies such as waste operating time.
Summary of the invention
This utility model is at above-mentioned the deficiencies in the prior art, and a kind of safe and convenient to use, the novel cataract operation cutter that can simplify operation technique greatly is provided.
The technical scheme that its technical problem that solves this utility model adopts is: novel cataract operation cutter, by the cutter tube, at least two scalpels, push rod, return spring and spring stationary barrier constitute, scalpel, push rod, return spring and spring stationary barrier all are arranged in the cutter tube, the bottom of cutter tube is provided with opening, the spring stationary barrier is fixed on cutter tube middle part, it is fixedly connected with corresponding push rod bottom that every handle of a knife scalpel passes the spring stationary barrier, the push rod top is provided with boss, return spring is socketed in the position between push rod convex platform and the spring stationary barrier, the position of corresponding boss has the saturating groove of " L " shape on cutter tube top, and boss passes groove and reaches cutter tube outside.
Position at the corresponding scalpel of cutter tube inwall has guiding groove.
Be provided with 3～4 scalpel in the cutter tube.
Described cutter tube is dismountable minute body structure.
During use, push the boss of push rod end gently along the saturating groove of " L " shape on the cutter tube, arrive the level trough end of groove until boss, at this moment, because of the elastic force of return spring is fixed boss, therefore the scalpel cutter head also is fixed on the outside of cutter tube bottom end opening.When needs are changed scalpel, earlier boss is resetted along the saturating groove of " L " shape, choose suitable scalpel repetition aforesaid operations again and get final product.
Cataract operation cutter of the present utility model is compared with prior art, has following outstanding beneficial effect:
(1) because in operation process, operator can own replacing scalpel, has avoided cooperating not tacit drawback between operator and the assistant, makes operator save operating time from line operate;
(2), significantly reduced the non-operation wearing and tearing probability of cutter head, the scalpel service life of the safety of the operation of raising and prolongation because the operation cutter head just stretches out the cutter tube in use.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model cataract operation cutter;
Accompanying drawing 2 is structural representations of cataract operation cutter spring stationary barrier shown in Figure 1.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
Novel cataract operation cutter is made of cutter tube 1, spring stationary barrier 5 and three groups of scalpels 2, push rod 3 and return springs 4 of being arranged in the cutter tube 1.
Cutter tube 1 is dismountable minute body structure, is provided with opening 6 in its bottom.Spring stationary barrier 5 is fixed on the middle part of cutter tube 1.It is fixedly connected with the bottom of corresponding push rod 3 that the handle of a knife of scalpel 2 passes spring stationary barrier 5.Push rod 3 tops are provided with boss 7.Return spring 4 is socketed in the position between push rod 3 convex platforms 7 and the spring stationary barrier 5.The position of corresponding boss 7 has the saturating groove 8 of " L " shape on cutter tube 1 top, and boss 7 passes groove 8 and reaches cutter tube 1 outside.Position at the corresponding scalpel 2 of cutter tube 1 inwall has guiding groove 9.
The consideration that needs for present clinical operation, three are respectively 15 ° of keratonyxis cuttves, sclera tunnel knife and 3.2 millimeters triangle stab knives to scalpel.
In addition, can also be as required and the handle of a knife position is set to different in sizely, be beneficial to scalpel depositing in the cutter tube.
Above-described embodiment, this utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
Claims (4)
