Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Example one

The embodiment of the utility model discloses eyelid retractor, it is shown with reference to figure 1 ~ 2, eyelid retractor includes eyelid hook 2 and bearing structure, and bearing structure includes two support arms 10, and two eyelid hooks 2 that eyelid retractor includes support respectively on two support arms 10. The two supporting arms 10 are integrally of a Y-shaped structure, the two supporting arms 10 can be opened and closed, when the ophthalmic surgery is carried out, the two eyelid opening hooks 2 support the eyelids of the two eyes respectively, the bulbar conjunctiva surface of the conjunctival sac is fully exposed, and a doctor carries out the ophthalmic surgery under a microscope.

The utility model discloses in the technical scheme, the inside cavity of eyelid hook 2, the inside and outside surface of eyelid hook 2 all is equipped with hole 4, hole 4 with the inside cavity intercommunication of eyelid hook 2, the eyelid hook 2 outside surface hole 2 connects negative pressure ware 8. Under the action of the negative pressure adsorption force of the negative pressure device 8, the conjunctival sac effusion enters the inside of the eyelid opening hook 2 through the hole on the inner side surface of the eyelid opening hook 2 and is sucked out from the hole 4 on the outer side surface of the eyelid opening hook 2, so that the safe and thorough drainage of the conjunctival sac accumulated water is realized.

Further, the hole 4 on the outer side surface of the eyelid opening hook 2 is connected with a guide hose 6, and the guide hose 6 is connected with the negative pressure device 8. In practical use, the diversion hose 6 can be a disposable infusion tube, the negative pressure device 8 preferably uses a 10ml syringe, one end of the disposable infusion tube is inserted into the hole 4 on the outer side surface of the eyelid opening hook 2, the syringe is connected with the other end of the infusion tube, the syringe is operated to suck to generate negative pressure, and the liquid outflow of the conjunctival sac is assisted to be discharged.

The outer surface of the eyelid hook 2 is provided with one of the holes 4 in order not to break the negative pressure environment. The inner surface of the eyelid hook 2 is provided with one or more holes 4, when one hole is provided, the liquid in the conjunctival sac enters the eyelid hook 2 from the hole under the negative pressure effect, when a plurality of holes are provided, the liquid in the conjunctival sac enters the eyelid hook 2 from the holes respectively under the negative pressure effect, the inner surface of the eyelid hook 2 is provided with a plurality of holes 4, the effusion discharging effect is better than that of one hole, but larger negative pressure is required, and at the moment, patients can feel uncomfortable. The number of the holes arranged on the inner measuring surface of the eyelid hook 2 can be adjusted according to the actual needs.

During ophthalmic surgery, the ophthalmic surgery adhesive film is not easy to cling to the face, so that hot air breathed by a patient in the surgery is scattered from the gap of the adhesive film, the surgical lens or the full-view reticulum lens is shielded by fog, the surgical field of vision is affected, and the problem can be solved only by stopping the surgery to wipe the lens. The eyelid retractor adopting the technical scheme of the embodiment can solve the problem that the surgical lens is shielded by fog. Specifically, the method comprises the following steps: referring to fig. 1, a tube 12 is connected to at least one of the support arms 10 of the support structure, and the tube 12 is disposed obliquely so that the tube 12 faces the mirror surface of the operating lens when the eyelid hook 2 supports an eyelid. The interior of the support arm 10 is hollow, and the hollow interior starts from the free end and ends at the connection part with the tube body 12, the tube body 12 is communicated with the hollow interior of the support arm 10, and the tube body 12 is used for demisting output gas. In actual operation, sterile air is input into the tube body 12 through the tail end of the supporting arm 10, and the sterile air output from the tube body 12 acts on the mirror surface of the surgical lens to remove mist on the mirror surface of the surgical lens.

Further, an end cover 16 is arranged at the end of the tube 12, the end cover 16 is used for preventing dust, and the end cover 16 covers the tube 12 after the operation is finished.

As a second technical solution of this embodiment, an air tube is disposed inside the supporting arm 10, one end of the air tube extends to the free end of the supporting arm 10, and the other end of the air tube is connected to the tube 12. The difference from the first solution is that in this solution sterile air enters the tube 12 from the air tube inside the support arm 10.

Referring to fig. 2, as a third technical solution of this embodiment, a transverse through hole 14 is formed in the support arm 10, and the pipe body 12 is located in the transverse through hole 14 and fixed. The difference with the first technical proposal is that the sterilizing air in the technical proposal directly enters the tube body 12 through the transverse through hole 14, and the transmission stroke of the sterilizing air is shortened.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto.
