Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an automatic eye injection device. Background Art

[0002] When an eye disease occurs, it is sometimes necessary to inject drugs into the eye for treatment. Taking the retina as an example, common retinal diseases include macular degeneration, diabetic retinopathy, retinal vascular disease, etc. Once retinal disease occurs, it is difficult to completely cure it, and there is also a risk of blindness. When performing an intraocular injection surgery, the existing technical means is to first manually disinfect and anesthetize the surface of the eyeball, and then the doctor manually inserts the needle into the vitreous body or the appropriate position of the retina and administers the medicine. The above method places extremely high demands on the doctor's surgical standards. The doctor can only rely on accumulated experience to perform eye injections. Not only is it difficult to control the depth of the needle inserted into the eye, but the process of injecting the drug into the eye is also quite laborious, resulting in a low success rate for eye injections.

[0106] As an embodiment of the present invention, the medicine storage box 2 is provided with a syringe shield (not shown) for protecting the syringe 7, which can be slid on the medicine storage box 2 along the width direction of the medicine box housing 1;

[0107] Among them, a shell return spring (not shown in the figure) is arranged between the syringe shield and the medicine storage box 2, which is used to bounce the syringe shield toward the outside of the medicine storage box 2; when the syringe shield is in the pop-up state, the syringe 7 is accommodated in the syringe shield, and when the syringe shield is in the retracted state, the syringe 7 is exposed outside the syringe shield.

[0108] As an embodiment of the present invention, the syringe shield comprises

[0109] a protective shell body 21 slidably disposed on the medicine storage box 2 and having an opening (not shown) for exposing the syringe 7; and

[0110] Two guard plates 211 hingedly connected to the upper and lower sides of the opening;

[0111] The shield body 21 is provided with a shield return spring connected to the shield 211 so that the two shields 211 have a tendency to engage with each other, thereby sealing the syringe 7 in the syringe shield.

[0112] Specifically, the guard plate 211 is an arc-shaped guard plate.

[0113] As an embodiment of the present invention, a first push block 212 is formed on the protective shell body 21, and a second push block 102 is fixedly configured in the medicine box shell 1;

[0114] When the medicine storage box 2 is inserted into the medicine box housing 1, the second push block 102 can push the first push block 212 to retract the protective shell body 21 into the medicine storage box 2, and then the two protective plates 211 are partially pushed open by the syringe 7 to expose the syringe 7 in the medicine box housing 1;

[0115] When the medicine storage box 2 is pulled out from the medicine box housing 1, the shield reset spring can pop the shield body 21 out of the medicine storage box 2, and the two shields 211 can snap the syringe 7 into the syringe shield again under the action of the shield reset spring.

[0116] To sum up, in the process of using the present application for eye treatment, it is first necessary to insert the medicine storage box 2 equipped with the syringe 7 into the medicine box shell 1; when inserting the medicine storage box 2, the puncturing component can puncture the rear cover 201 and the front cover 202 in a linked manner to conduct the air pump assembly 4, the medicine storage bag and the medicine outlet 100; after the medicine storage box 2 is inserted, the limiting assembly 3 can confine the medicine storage box 2 in the medicine box shell 1, and the syringe linkage plate 55 can confine the syringe 7 along the length direction of the medicine box shell 1.

[0117] Next, a related three-dimensional mobile device or a multi-degree-of-freedom robotic arm is used to move the present application to an appropriate position above the patient's eye, and then the above-mentioned automatic eye injection device is fixed; a disinfectant is injected from the corresponding drug storage bag into the human eye through the air pump assembly 4 to disinfect the eye, and an anesthetic is injected from the corresponding drug storage bag into the human eye through the air pump assembly 4 to anesthetize the eye.

[0118] After that, the syringe telescopic drive motor 50 is started to slide the syringe 7 toward the outside of the medicine box shell 1; during this process, the syringe 7 gradually slides away from the medicine storage box 2, and when the third hook block 111 abuts against the third hook groove 730, the syringe shell 71 slides into the sheath 73 to reveal the needle from the hollow cone 732; when the needle is completely revealed from the hollow cone 732, the syringe telescopic drive motor 50 is stopped.

[0119] Subsequently, the distance between the needle tip and the intraocular injection location is determined. If the needle tip has not reached the predetermined location, the cannula drive motor 90 is sequentially activated to extend the telescopic cannula 11 outward from the fixed cannula 10. Furthermore, the syringe extension drive motor 50 is sequentially activated to cause the syringe 7 to move forward a corresponding distance following the telescopic cannula 11 until the needle tip reaches the intraocular injection location. Once the needle tip reaches the intraocular injection location, the cannula drive motor 90 is deactivated to secure the telescopic cannula 11 relative to the fixed cannula 10.

[0120] Continue to run the syringe telescopic drive motor 50. Since the position of the syringe 74 is limited on the hollow cone 732 and the hollow cone 732 is limited on the telescopic sleeve 11, the piston 72 can be pushed into the syringe 74 by the syringe linkage plate 55, so that the medicine in the syringe 74 is injected into the eye through the needle.

[0121] When the injection is completed, the syringe telescopic drive motor 50 is started in reverse to pull the needle out of the eye and reset the syringe plug block 710 in the syringe mounting groove 22; under the action of the sleeve drive motor 90, the telescopic sleeve 11 is also reset to the fixed sleeve 10.

[0122] Next, the air pump assembly 4 is used to inject a hemostatic agent from the corresponding drug storage bag into the human eye to perform eye hemostasis treatment, and the above-mentioned automatic eye injection device is removed after the hemostasis treatment is completed.

[0123] When the eye treatment is completed, the wedge-shaped toggle block 311 is pressed to unlock the medicine storage box 2, and the medicine storage box 2 together with the syringe 7 is taken out for further processing.

[0124] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
