Abstract
The utility model discloses a multifunctional lens capsule scalpel which is mainly used for phacoemulsification operation, in particular to a scalpel for incising lens capsule membrane, which comprises a disposable viscoat injector, a scalpel body and a scalpel head, and is characterized in that the scalpel body is tubular, the interior of the scalpel body is hollow and used as viscoat channel. A joint opening is arranged on the left end of the scalpel body, the scalpel body in 2/3 of the distance to the joint opening is bent with angle of 130 degrees-140 degrees. The right end of the scalpel body is provided with a scalpel head and the viscoat outlet is above the scalpel head. The scalpel head has double cutting edge and is shaped like an inverted triangle, the double cutting edge is sharp. The included angle of the scalpel head and the scalpel body is 90 degrees. The joint opening of the multifunctional lens capsule scalpel is connected with the rubber head of the disposable viscoat injector. The utility model integrates scalpel with viscoat injector to a whole so that during the operation, viscoat can be injected continuously for continuously maintaining anterior chamber and facilitating the operation. The multifunctional lens capsule scalpel reduces the number of injector on inserting into anterior chamber, reduces operation time, and avoids the damage to corneal endothelium layer and complications; thereby, operation is ensured to be safe and reliable.
Description
Technical field:
This utility model relates to a kind of ophthalmologic operation medical apparatus and instruments, is mainly used in the cataract ultrasonic emulsification excising operation, cuts the multifunction surgical cutter of crystalline peplos.
Background technology:
At present, the treatment cataract generally all adopts the ultrasonic emulsification enucleation.Behind the surgical incision anterior chamber, because of aqueous humor overflows, the anterior chamber shoals, and makes the operation technique limited space, and the influence operation is carried out.Take place for making things convenient for operation technique and reducing complication, need in the anterior chamber, to inject viscoelastic agent earlier, the anterior chamber space is recovered, and then cut the capsule cutter with crystalline lens and cut anterior capsule.Repeated multiple times enters the anterior chamber like this, not only prolongs operating time, and damages corneal endothelial layer easily, increases patient's misery, even causes cornea to lose compensatory severe complication.
The utility model content:
For injection viscoelastic agent and crystalline peplos otch in the pioneering operation that exists in the solution above-mentioned background technology are finished with two kinds of apparatuses respectively, operating time is long, and damage corneal endothelial layer easily, even cause cornea to lose compensatory problems such as severe complication, this utility model will provide a kind of and integrate the viscoelastic agent syringe and crystalline lens is cut the capsule scalpel, operating time is short, reduces complication and takes place, and safe and reliable multi-functional crystalline lens is cut the capsule scalpel.
The technical solution of the utility model realizes in the following manner:
A kind of multi-functional crystalline lens is cut the capsule scalpel, comprises disposable viscoelastic agent syringe, cutter head and cutter hub, it is characterized in that: cutter hub in a tubular form, cutter hub hollow is the viscoelastic agent passage.The cutter hub left end has interface, cutter hub 130 °～140 ° of the bendings that make progress apart from interface 2/3 place, and the cutter hub right-hand member is a cutter head, and there is the viscoelastic agent outlet top of cutter head portion, and cutter head is the twolip del, and blade is sharp, and cutter head and cutter hub are 90 °.Multi-functional crystalline lens is cut capsule scalpel interface and is connected with disposable viscoelastic agent syringe nipple.
Good effect of the present utility model:
1, this apparatus integrates the viscoelastic agent syringe and crystalline lens is cut the capsule scalpel, viscoelastic agent can be injected in the use to cut two steps with crystalline peplos and unite two into one.
2, with this apparatus in cutting the cyst membrane process, can constantly inject viscoelastic agent so that the anterior chamber remains, help the operation carry out smoothly.
3, reduced viscoelastic agent syringe turnover anterior chamber's number of times with this apparatus, can avoid damaging the generation of corneal endothelial layer and complication, operation safety is reliable.
Description of drawings:
Fig. 1 is a population structure sketch map of the present utility model.
Fig. 2 is that the K of Fig. 1 is to view.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: the concrete structure of cutting the capsule scalpel at the multi-functional as can be seen crystalline lens of Fig. 1, Fig. 2.It comprises disposable viscoelastic agent syringe, cutter head and cutter hub.
Cutter hub (2) in a tubular form, hollow bulb is viscoelastic agent passage (3), the cutter hub left end has interface (1), cutter hub (2) 130 °～140 ° of the bendings that make progress apart from interface (1) 2/3 place, best angle is 135 °, cutter hub (2) right-hand member is cutter head (4), cutter head (4) is the twolip del, blade is sharp, cutter head (4) and cutter hub (2) in vertical direction, there is viscoelastic agent outlet (5) top of cutter head.Syringe nipple (6) is inserted in the connector (1) of cutter hub (2).
In cataract operation, after cutting the anterior chamber, the disposable syringe nipple that viscoelastic agent at first will be housed inserts multi-functional crystalline lens and cuts in the interface of capsule scalpel, to cut then after capsule scalpel level enters the anterior chamber, viscoelastic agent injects the anterior chamber by nipple, cutter hub viscoelastic agent passage, outlet, after the anterior chamber recovers, the cutter head of again multi-functional crystalline lens being cut the capsule scalpel vertically downward, cutting a diameter on anterior capsule is 5～6mm annular incision, finish the otch rear blade and be the additional viscoelastic agent that injects in level position, withdraw from the anterior chamber, the anterior chamber is remained.Both avoided in cutting the capsule process, damaging corneal endothelial layer, avoided repeated multiple times turnover anterior chamber again, and the viscoelastic agent injection had been united two into one with phacocyst membranectomy two steps, shortened operating time, and reduced complication and take place, reached operation safety timesaving purpose.
Claims (1)
- A kind of multi-functional crystalline lens is cut the capsule scalpel, comprise disposable viscoelastic agent syringe, cutter hub (2) and cutter head (4) etc., it is characterized in that: cutter hub in a tubular form, hollow in the cutter hub, be viscoelastic agent passage (3), the cutter hub left end has interface (1), cutter hub is 130 °～140 ° bendings apart from interface 2/3 place, the cutter hub right-hand member is cutter head (4), the cutter head top is viscoelastic agent outlet (5), and cutter head is the twolip del, and blade is sharp, cutter head and cutter hub are 90 °, and multi-functional crystalline lens is cut capsule scalpel interface and is connected with disposable viscoelastic agent syringe nipple (6).
