Abstract
The utility model discloses an anterior chamber injection and sucking device for ophthalmologic operations, which is mainly composed of a water inlet pipe and a water outlet pipe, wherein, the water outlet pipe is arranged in the water inlet pipe, and a sleeve pipe is arranged outside of the water outlet pipe. Incision is small, and injury is light. The depth of anterior chambers can be maintained in the process of injection and suction, and the utility model can cut during the injection and suction. Large hematocele blocks or cortex of crystalline lens can not clog a needle head. The utility model is suitable for the operations of traumatic cataract, congenital cataract of babies, anterior chamber hemorrhage, anterior chamber empyema, anterior vitreous body cut, etc.
Description
This utility model relates to a kind of medical sucting apparatus, and special and ophthalmologic operation anterior chamber injection aspirator has the pass.
It is one of common operation of ophthalmology that the anterior chamber annotates the suction operation, is generally used for treating infant cortical cataract, hyphema empyema etc.At present, Chang Yong notes suction spindle head is that two syringe needles are fixed together side by side clinically, pipe water inlet during operation, the deficiency of this notes suction spindle of a pipe water outlet head is that volume is big, otch is big during operation, and damage is serious, and bigger cortex of lens or hematocele piece block the water outlet syringe needle easily.
The purpose of this utility model is to provide a kind of volume little, simple in structure, and operative incision is little, and damage is light, and can inhale the limit cutting by marginal not, is difficult for the injection aspirator tool that blocks.
Technical solution of the present utility model is such: the inside that outlet pipe is arranged on water inlet pipe, outlet pipe adopts bilayer sleeve simultaneously, inner sleeve inside pipe casing outside moves, near the operation port of trocar sheath depression is arranged, when bigger cortex of lens or hematocele piece enter the trocar sheath recess, promote inner sleeve and just it can be cut, in order to sucking-off from the water outlet inner sleeve.
This utility model has dwindled the volume of injection aspirator owing to adopt the jacket layer design, makes operative incision little, and damage is light, can keep anterior chamber depth in annotating the suction process, and can inhale the limit cutting by marginal not, and big hematocele piece or cortex of lens are difficult for blocking syringe needle.This device is particularly suitable for operations such as traumatic cataract, infant congenital cataract, hyphema, hypopyon, anterior vitreous cutting.
Below in conjunction with accompanying drawing this utility model is further elaborated.
Accompanying drawing 1 is the structural representation of an embodiment of this utility model.
Accompanying drawing 2,3,4 is respectively the structural representation of this utility model the foregoing description water inlet pipe, outlet pipe sleeve pipe, outlet pipe.
Structure as shown in drawings, 1 is water inlet pipe, water inlet pipe 1 is provided with water inlet 5 and 5 and is provided with outlet pipe trocar sheath 2 in water inlet pipe 1 central authorities, trocar sheath 2 has a housing 8 near an end of water inlet 5, be provided with sealing ring 6 between housing 8 and the water inlet pipe 1, trocar sheath 2 stretch out water inlet 5 ', and a pit-holes 4 arranged near port, ejection can enter outlet pipe 3 since then, and outlet pipe 3 is located at the inside of sleeve pipe 2, and pipe 3 can be twitched in pipe 2, be positioned at housing 8 on the outlet pipe 3 spring 7 is arranged, in the outside of housing 8 operating grip 9 and outlet 11 are arranged on the outlet pipe 3, when spring 7 extended naturally, the suction inlet 10 of outlet pipe 3 did not stretch out the pit-holes 4 of trocar sheath 2.During operation, connect water inlet 5, water is from water inlet 5 ' enter the anterior chamber, to keep anterior chamber depth.Outlet 11 is communicated with syringes, sucking-off cortex of lens or hematocele piece etc., and when bigger cortex or hematocele piece enter pit-holes 4, can operating grip 9, move out water pipe 3, with its cutting, with antifouling outlet pipe 3.
Claims (2)
1, a kind of manual biting type ophthalmologic operation anterior chamber injection aspirator tool, form by water inlet pipe and outlet pipe, it is characterized in that: outlet pipe 3 is arranged on the central authorities of water inlet pipe 1, the outside of outlet pipe 3 also has a sleeve pipe 2, outlet pipe 3 can be twitched in sleeve pipe 2, and sleeve pipe 2 has a pit-holes 4 near the operation port.
2, according to claim 1 described injection aspirator, it is characterized in that: also be provided with an elastic recovery device 7 on the outlet pipe 3.
