Abstract
The utility model relates to a two-way push-injection exchanger in an ophthalmologic operation device. The two-way push-injection exchanger comprises a needle cylinder, wherein a pintle and pistons connected with the pintle are arranged in the needle cylinder; the pistons are respectively arranged at two ends of the pintle; two ends of the needle cylinder are divided into an injection chamber and a suction chamber by the two pistons; nipples are respectively arranged in the injection chamber and the suction chamber; a handle extending out of the needle cylinder is arranged at the middle part of the pintle in a matching manner; and a sliding chute convenient for pushing the pintle by the handle is formed in the side wall of the needle cylinder and the extending position of the handle. When the ophthalmologic operation is carried out, the two-way push-injection exchanger disclosed by the utility model can be operated by one person to simultaneously carry out equivoluminal suction, and thus the balance of pressure in eyes is maintained, the risk and the operation difficulty of the ophthalmologic operation are reduced and operative complications are reduced.
Description
Technical field
This utility model relates to the two-way exchanger of injecting in a kind of ophthalmic surgical device.
Background technology
Clinically, in ophthalmologic operation, when pumping liquid or gas, need to keep the constant of intra-ocular pressure power in the eyeball, avoid occuring other postoperative complications such as fulminant Suprachorodal hemorrhage.In prior art, carry out ophthalmic liquid gas when suction to be difficult to guarantee that intraocular pressure is constant, and operation is difficult to control, very high to the requirement of surgical staff, also increased operation risk simultaneously.
The utility model content
The problem that this utility model exists for prior art, but provide a kind of one man operation to carry out simultaneously the two-way exchanger of injecting of equal-volume suction, reduce ophthalmologic operation risk and operation easier, reduce postoperative complication.
The purpose of this utility model is to realize like this, a kind of two-way exchanger of injecting, comprise syringe, be provided with pintle and the piston that is connected with pintle in syringe, described pintle two ends are equipped with piston, and two-piston is separated into injecting cavity and suction chamber with syringe inner chamber two ends, and described injecting cavity and suction chamber are respectively equipped with nipple, described pintle middle part coordinates to be provided with stretches out the outer handle of syringe, and the sidewall of syringe and handle extended position is provided with is convenient to the chute that handle promotes pintle.
During two-way injector of the present utility model is used, nipple that injecting cavity is connected with suction chamber is connected with venoclysis needle respectively, injecting cavity is pumped into liquid or the gas of the certain volume that will inject ophthalmic, two transfusion needles impose on respectively the relevant position of patient's eyeball simultaneously, can realize that marginal not penetrates limit suction, make draw volume keep balance, thereby keep patient's intraocular pressure constant, operation easier is little, reduces the postoperative complication that in single needle liquid gas exchange process, the intraocular pressure fluctuation is brought out, and reduces operation risk.
As a kind of improvement of the present utility model, described nipple is separately positioned on the both ends of injecting cavity and suction chamber.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 nipple; 2 injecting cavities; 3 syringes; 4 pintles; 5 hands handles; 6 chutes; 7 pistons; 8 suction chamber.
The specific embodiment
Be illustrated in figure 1 as the two-way exchanger of injecting of the present utility model, comprise syringe 3, be provided with pintle 4 and the piston 7 that is connected with pintle 4 in syringe 3, and pintle 4 two ends are equipped with piston 7, two-piston 7 is separated into injecting cavity 2 and suction chamber 8 with syringe 3 inner chamber two ends, injecting cavity 2 and suction chamber 8 both ends are provided with respectively nipple 1, and pintle 4 middle parts coordinate to be provided with stretches out the outer handle 5 of syringe 3, and the sidewall of syringe 3 and handle 5 extended positions is provided with is convenient to the chute 6 that handle 5 promotes pintles 4.
During two-way injector of the present utility model is used, the nipple 1 that injecting cavity 2 is connected with suction chamber is connected with venoclysis needle respectively, injecting cavity 2 is pumped into liquid or the gas of the certain volume that will inject ophthalmic, two transfusion needles impose on respectively the relevant position of patient's eyeball simultaneously, can realize that marginal not penetrates limit suction, make draw volume keep balance, thereby keep patient's intraocular pressure constant, reduce the postoperative complication that in single needle liquid gas exchange process, the intraocular pressure fluctuation is brought out, operation easier is little, reduces operation risk.
This utility model is not limited to above-described embodiment; every on the basis of the disclosed technical scheme of this utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the scope of this utility model protection.
Claims (2)
1. two-way exchanger of injecting, comprise syringe, be provided with pintle and the piston that is connected with pintle in syringe, it is characterized in that, described pintle two ends are equipped with piston, and two-piston is separated into injecting cavity and suction chamber with syringe inner chamber two ends, and described injecting cavity and suction chamber are respectively equipped with nipple, described pintle middle part coordinates to be provided with stretches out the outer handle of syringe, and the sidewall of syringe and handle extended position is provided with is convenient to the chute that handle promotes pintle.
