Abstract
The utility model belongs to a surgical implement for the extracapsular cataract extraction of the department of ophthalmology, which is composed of a needle head part, a regulator, a charge tube, a sealing gasket, a crank reciprocating mechanism, a drive mechanism, a motor, a battery unit and an outer case. The reciprocal motion of the needle head in a needle catheter is used for making the high frequency pricking cutting cystoma and is generated by a guide post and a crank. When the needle head of the surgical implement for the extracapsular cataract extraction of the department of ophthalmology is used for pricking in high frequency, the travel can be adjusted, the charge can be simultaneously carried out, and the speed can be regulated. The size of the cutting cystoma and the shape of the cutting cystoma can be randomly controlled; the configuration and the volume are small, and the structure is simple. The surgical implement for the extracapsular cataract extraction of the department of ophthalmology, which has no tractive function on crystalline lenses can avoid the mutilation of a suspensory ligament and the luxation of the lenses and can reduce the occurrence of the complicating diseases of sequelae, etc. The surgical implement for the extracapsular cataract extraction of the department of ophthalmology has the advantages of easy operation and safe use and can be adapted to operations with various positions and angles.
Description
This utility model belongs to a kind of treatment ophthalmology ECCE surgical instrument.
Cataract is the ophthalmology frequently-occurring disease, also be one of common diseases causing blindness, the clinical treatment means mainly are to rely on cataractopiesis (capsule is outer, in the capsule, pin inhales art etc.), in ECCE, cutting capsule is one of committed step, and common tool has capsule tweezer, discission needle (cutter) etc.It is imperfect that the utensil of currently used said method and use causes cutting capsule easily, cutting the shape size of capsule sheet can not arbitrarily control, and manipulates shortcomings such as inconvenience, also easily crystalline lens is played traction action, can make the Suspensory ligament dialysis, cause luxation of lens, back to send out complication such as barrier.
The purpose of this utility model provides a kind of surgical instruments such as ECCE, pin suction art, membranous cataract enucleation that are used for.
This utility model is achieved in that motor and a pair of friction pulley drive mechanism and crank reciprocator is housed in housing.In addition, also comprise syringe needle part and actuator, liquid injection pipe and set of cells and control transmission line of electricity.
The needle section branch comprises syringe needle, wire guide.Syringe needle can move back and forth in wire guide, the crooked inclination angle of wire guide port, and oral area is parallel with axis, and the syringe needle diameter is the 0.2-0.4 millimeter, and wire guide is syringe needle 5#-9#, and length is the 20-60 millimeter.
Syringe needle and guide pillar are fixed as one, the stroke distances that actuator scalable syringe needle stretches out the needle guide mouth of pipe, and its stroke is regulated at the 0-3 millimeter.
Drive mechanism of the present utility model realizes that by being contained in the upper conical friction pulley drive of motor shaft eccentric bushing friction pulley axial 90 degree change transmissions, regulate motor and enter the degree of depth, spring moves axially the eccentric bushing friction pulley, realizes speed governing, and gear ratio is between 1:1-1:1.5.
Crank of the present utility model reciprocator is by friction cone, drives eccentric bushing friction pulley crank, drives guide pillar by crank and realizes that syringe needle moves back and forth.Eccentric bushing friction pulley ［ 8 ］ eccentric distance 0.125-1.25 millimeter.Reciprocal 2000 times-4000 times of syringe needle per minute, the syringe needle reciprocating stroke is the 0.25-2.5 millimeter.
This utility model is adorned a liquid injection pipe at housing seal pad front end, to remain on the reciprocating while of syringe needle, liquid injects the anterior chamber by the needle point mouth, to keep the anterior chamber to exist, sealing gasket is in the middle of actuator and guide pillar, to prevent that flow of liquid from going into guide pin bushing, the liquid injection pipe diameter is the 0.5-4 millimeter, and sealing gasket thickness is the 0.5-5 millimeter.
This utility model motor power is by battery-powered, and set of cells is connected by lead control knob and motor.
When this utility model cuts capsule in the pricking method of syringe needle high frequency, adjustable stroke and fluid injection simultaneously, and adjustable speed, the external form volume is little, and is simple in structure, and crystalline lens is not had traction action, can arbitrarily control the size shape of cutting capsule, capsule is insufficient, operation is cumbersome for cutting of having prevented that surgical instrument caused in the past, to lenticular traction action, reduced the generation of complication such as back barrier, luxation of lens, and the operation under all places and the angle when being adapted to perform the operation.

Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing.
Motor ［ 15 ］ is housed in housing ［ 14 ］ end cap ［ 16 ］, the friction cone ［ 11 ］ that is fixed on motor shaft end drives another eccentric bushing friction pulley ［ 8 ］ rotation, eccentric bushing friction pulley ［ 8 ］ is contained on the axle ［ 9 ］ with spring, spring ［ 10 ］ promotes eccentric bushing friction pulley ［ 8 ］ and is close to motor friction cone ［ 11 ］. eccentric bushing friction pulley ［ 8 ］ and crank ［ 7 ］. and guide pillar ［ 5 ］ is connected, and realizes moving back and forth.Syringe needle ［ 1 ］ is fixed on the guide pillar ［ 5 ］, guide pillar ［ 5 ］ is partly led by housing ［ 14 ］ guide pin bushing. in housing ［ 14 ］ and guide pillar ［ 5 ］ front end be provided with sealing gasket ［ 4 ］ and stop liquid to flow in the housing ［ 14 ］, in sealing gasket ［ 4 ］ front, fixing on the housing ［ 14 ］ liquid injection pipe ［ 12 ］ and with take over ［ 13 ］ and be communicated with.
Actuator ［ 3 ］ and housing ［ 14 ］ thread connection, wire guide ［ 2 ］ tapering is fixed on the actuator ［ 3 ］, regulates actuator ［ 3 ］. and just can adjust wire guide ［ 2 ］ distance of bearing pin ［ 9 ］ relatively, syringe needle ［ 1 ］ can move back and forth in wire guide ［ 2 ］ lining.Wire guide ［ 2 ］ port is a curved incline angle, to guarantee the direction of motion and the angle of syringe needle ［ 1 ］.
During use by battery-powered, connect lead ［ 17 ］ by control knob and motor ［ 15 ］ is rotated and make friction cone ［ 11 ］ drive eccentric bushing friction pulley ［ 8 ］ and make crank ［ 7 ］ drive guide pillar ［ 5 ］ to move back and forth at a high speed, thereby realize that the high frequency pricking method cuts capsule.
