Description
Technical field
This utility model relates to a kind of operation probe, refers in particular to a kind of cataract emulsifying operation that applies to, in order to remove the cataract emulsifying operation probe of crystalline lens kernel.
Background technology
Cataract is meant that the ophthalmic of muddy phenomenon takes place the eyeball crystalline lens; It not only can make visual deterioration, and is opaque and white at last, stops light entering eyes and makes patient's Loss Of Vision; Present Therapeutic Method; Be to utilize cataract emulsifying operation that the crystalline lens kernel of muddiness part is removed, transplant in eyeball with intraocular lens, thereby recover patient's vision.
General cataract emulsifying operation is near the wheel portion of cornea, make a 0.8mm to 1.0mm a little otch, pours into the elastic force viscous fluid and keeps the anterior chamber space; Then; Carry out before the crystalline lens capsule thin film and tear and strike off, then little otch is extended to 1.8mm, 2.0mm, 3.0mm or 6.0 to 7.0mm, decide according to the needs of different apparatuses; Design 1.8mm with present is its limit, because there are some bottlenecks to be difficult to break through.
The existing cataract emulsifying employed emulsifying probe of performing the operation like Fig. 6 and shown in Figure 7, mainly is divided into intermediary metal catheter 10 and silica gel catheter 20 two parts that are placed on the outside, and in the front end of this metal catheter 10 oblique section 101 is set.During operation, as shown in Figure 8, the emulsifying probe stretches near the otch D1 the cornea D wheel portion; And in cornea D in addition side make a via hole D2, by intermetallic metal conduit 10 output ultrasonic energy, cooperate the oblique section 101 of front end; Utilize the method that pushes away forward, shovels; To crystalline lens kernel E root out, the broken and step drawn, the silica gel catheter of overcoat then constantly pours into anterior chamber F with the isotonic concentration continuous normal saline, makes flushing and keep that anterior chamber F is complete and unlikely to subside.
Otch D1 when carrying out this cataract emulsifying operation is small more, is not easy to cause the leakage of anterior chamber F liquid more, also keeps the spatial integrity of anterior chamber F more easily; But too small otch D1 can block silica gel catheter 20; And make transfusion obstructed, and then cause anterior chamber F to subside, cause operative failure; So the emulsifying of this kind prior art probe has following shortcoming:
1. its emulsifying probe comprises an intermetallic metal conduit 10 overcoats and a silica gel catheter 20, thereby to carry out the otch that cataract emulsifying performs the operation be least limit with 1.8mm to 2.0mm, and patient's postoperative is longer required recovery time.
2. it carries out cataract emulsifying when operation, the emulsifying probe be with push away, the shovel mode operates, thereby is prone to patient's the girder ligament and the support power of back capsule are damaged.
3. when it pushed away, shovels operation with the emulsifying probe, this emulsifying probe sheltered from operator's sight line easily, hindered the carrying out of operation, and then the quality of influence operation.
4. its technical difficulty of carrying out cataract emulsifying operation is high, thereby operator's learning curve and time increase.
The utility model content
When popping one's head in use in view of the cataract emulsifying operation of above-mentioned prior art; Exist the otch that carries out cataract emulsifying operation excessive; Patient's post-operative recovery time is long; The shortcoming that the scope of application of implantable artificial crystalline lens is little, the technical problem that this utility model will solve be, a kind of cataract emulsifying operation probe of being convenient to operate, can reduce the otch of cataract emulsifying operation is provided.
For solving the problems of the technologies described above; This utility model provides a kind of cataract emulsifying operation probe; It comprises: one be used to export ultrasonic energy metal catheter and be used for from the cornea side input isotonic concentration normal saline to anterior chamber's butterfly type transfusion needle; This metal catheter and this butterfly type transfusion needle are independent respectively, and this metal catheter front end is provided with an olecranon shape hook part.During operation, this metal catheter stretches in the cornea, by this metal catheter output ultrasonic energy; Cooperate the hook part of front end to take the contrary operation mode; With the shatter absorption of crystalline lens kernel, this butterfly type transfusion needle is imported the isotonic concentration normal saline from the side with the action of digging, cut out, harrowing, and the bottle position height of adjustment splendid attire capable of using transfusion; The complete anterior chamber space of keeping, unlikely generation seepage is subsided.
As preferably, form an opening in this hook part.
As preferably, the sheathed one deck silica gel thin film of this metal catheter outer rim, in order to intercept when high-energy is operated, metal catheter directly contacts with cornea tissue.
Compared with prior art, the cataract emulsifying of this utility model operation probe has following advantage:
The major advantage of the cataract emulsifying operation probe of this utility model; Be that its metal catheter and butterfly type transfusion needle are independent respectively; Can realize real miniature incision cataract emulsifying operation; Patient's post-operative recovery is quick, and if incision extension, the intraocular lens that then is fit to various forms, size is implanted.
The minor advantage of the cataract emulsifying operation probe of this utility model is the olecranon shape hook part design of its metal catheter front end, can reach the effect that single-point digs, cuts out, harrows, and reduces prior art emulsifying probe and pushes away, shovels the support power injury to girder ligament and back capsule.
Another advantage of the cataract emulsifying of this utility model operation probe, metal catheter is taked the contrary operation mode when operation, and can get rid of the sight line that shelters from the operator fully, hinders the situation of carrying out in operation, thereby guarantees the quality of performing the operation.
The another advantage of the cataract emulsifying of this utility model operation probe is can reduce when it undergos surgery or fully without the elastic force viscous fluid, and lowers the phenomenon that patient's postoperative intraocular pressure increases.
An advantage again of the cataract emulsifying operation probe of this utility model, metal catheter is taked the contrary operation mode when being to perform the operation, thereby can significantly reduce operator's learning curve and time.
