Embodiment 1

[0037] The propulsive gas injection device of the present embodiment, such as figure 1 - image 3 As shown, it includes: an airbag 1, an accommodating shell 2 and an infusion head 3, the airbag 1 is made of a flexible material, and its interior is suitable for setting filling gas for maintaining intraocular pressure; the accommodating shell 2 is made of plastic material, and the The airbag 1 is arranged inside the accommodating shell 2 to prevent accidental contact with the airbag 1 . In this embodiment, the filling gas is preferably an inert gas.

[0038] The housing shell 2 has an air pump interface 4 and an air injection interface 5, the air pump interface 4 is suitable for communicating with the inner cavity of the housing shell 2, reducing pipelines, compact structure, and no pipeline dead space; The gas interface 5 is suitable for connecting with the gas injection head 3 and communicating with the inside of the air bag 1;

[0039] When in use, the doctor holds the hou...

Embodiment 2

[0050] The vitrectomy system of this embodiment includes the push-type gas injection device described in Embodiment 1.

[0051] The vitrectomy system also includes:

[0052] An air pump, the air pump is connected to the air pump interface 4, and is suitable for pumping air into the inner cavity of the housing shell 2; the air pump can be selected according to actual needs with a flow controllable air pump.

[0053] The vitrification system also includes: a control unit, which is arranged on the air pump and controls the action of the air pump; the control unit is connected to the mobile phone or computer through communication, and then controls the air intake of the air pump through the mobile phone or computer.

[0054] When in use, you can set the corresponding parameters of the air pump on the mobile phone or computer, such as flow rate, time, etc., and the operation is convenient and fast.

Abstract

The invention relates to the technical field of medical instruments, in particular to a push type gas injection device and a vitreous cutting system thereof. The air injection device comprises an air bag, a containing shell and an air injection head, the air bag is made of flexible materials, and filling air for maintaining intraocular pressure is arranged in the air bag. The containing shell is made of plastic materials, and the air bag is arranged in the containing shell. The containing shell is provided with an air pump connector and an air injection connector, and the air pump connector is suitable for communicating with an inner cavity of the containing shell; the gas injection connector is suitable for being connected with a gas injection head and communicates with the interior of the airbag; the air injection power is provided by the air pump, a doctor only needs to hold the containing shell with the hand in the operation process, therefore, the operation difficulty is reduced, and due to the fact that the containing shell is made of plastic materials, the air bag in the containing shell cannot be disturbed when the containing shell is held. The air injection power is provided by the air pump, the air injection amount is controlled by controlling the deformation of the air bag, and the deformation of the air bag is continuous and soft, so that the air injection amount can be accurately controlled, the effect of controllable intraocular pressure is achieved, and the filling air is located in the air bag and cannot be polluted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a push-type gas injection device and a vitrectomy system thereof. Background technique [0002] The vitreous is a semi-solid gel-like substance in the eye that fills the vitreous cavity. Under normal circumstances, the vitreous has good light transmission, so that the retina and choroid are attached. If there is a lesion in the vitreous body, the light person will feel that there are mosquitoes flying in front of the eyes when looking at things, and the severe case can completely block the light and cause blindness. It may also cause surrounding tissue lesions, such as retinal detachment, and damage the entire eyeball. Surgery for treatment. [0003] In the vitrectomy operation, after the cutting step is completed, silicone oil, air or inert gas needs to be injected into the vitreous cavity to maintain the intraocular pressure of the eyeball. Currently, a syringe is use...
