Description

TECHNICAL FIELD

[0001] The utility model relates to ophthalmic surgery liquid drainage technical field, especially in a kind of stick formula ophthalmic surgery liquid drainage device. BACKGROUND

[0002] At present, in most intraocular surgery of ophthalmology, eye lid speculum is used to open the eye to achieve the purpose of exposing the surgical field. To maintain intraocular pressure, perfusion fluid is used in surgery. Due to the small palpebral fissure of the patient, conjunctival relaxation and other reasons, the accumulated liquid cannot be discharged in time, affecting the visibility of the operator to the surgical field and the surgical effect.

[0003] At present, there are two methods to solve this problem in actual work. One is to use a cotton swab or other tools to guide the accumulated liquid out by the instrument nurse or assistant, and the other is to hang a water droplet-like pendant on the temporal side of the surgical eye to make the liquid flow out. The first method is not effective when the liquid accumulates in the patient. The second method is that the surgical field is originally small, and the operator needs to operate with both hands. Non-professional tools may block the view and touch the operator, which may affect the operation. The third method is that continuous drainage work may affect the intraocular lens implantation and the transfer of surgical instruments by the instrument nurse. The fourth method is that the weight hanging has the risk of damaging the eye tissue. Therefore, we provide a stick formula ophthalmic surgery liquid drainage device. UTILITY MODEL CONTENT

[0004] The main purpose of the utility model is to provide a stick formula ophthalmic surgery liquid drainage device, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] A stick formula ophthalmic surgery liquid drainage device, comprising an air bag, the upper end and the lower end of the air bag are arc-shaped structures, the front part and the rear part of the outer surface of the air bag are fixedly connected with a plurality of anti-skid protrusions, the plurality of anti-skid protrusions are arc-shaped structures, the upper end of the air bag is fixedly connected with a hose, the end of the hose away from the air bag is movably connected with a dust cover, the diameter of the dust cover is greater than the diameter of the hose, the hose is a "U"-shaped structure, the left part of the outer surface of the air bag is fixedly connected with a glue layer, and the glue layer is not in contact with the plurality of anti-skid protrusions.

[0007] Preferably, the plurality of anti-skid protrusions are vertically and equidistantly distributed.

[0008] Preferably, the height of the hose is greater than the height of the air bag.

[0009] Preferably, the air bag is a hollow structure.

[0010] Preferably, the air bag and the hose are in communication.

[0011] The utility model has the advantages of the following:

[0012] In the utility model, the air bag is provided with a hose at the upper end, and the air bag is both a pressure device and a storage space. During use, the air bag is pasted on the temporal side of the eye at any position through the adhesive layer on the outer surface of the air bag, and the opening at the end of the hose away from the air bag is located at the lowest point of the conjunctival sac. When the effusion in the conjunctival sac affects the operation of the operator during the operation, the instrument nurse only needs to gently squeeze the air bag, and the retained liquid can be quickly emptied and flows into the air bag. The device is convenient and fast, the slender hose does not affect the operation space of the operator, the whole device is disposable, and the sterile operation of the operation is also ensured.

[0017] In order to make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the utility model is further described in combination with specific implementation manners.

[0018] In the description of the utility model, it should be explained that the positions or location relations indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end" and "the other end" are the positions or location relations shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and cannot be understood as indicating or implying that the indicated devices or elements must have a specific position, a specific position and operation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the utility model, it is necessary to explain, unless there is definite stipulation and limitation, the term "installation", "set with", "connection" and the like should be understood broadly, for example "connection", can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through intermediate medium, can be the communication inside two elements, for ordinary skilled in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to specific circumstances.

[0020] Please refer to Figs. 1-3 The utility model provides a technical scheme:

[0021] A kind of eye surgery liquid drainage device of adhesive type, including air bag 1, air bag 1 upper end and lower end are arc surface structure, air bag 1 outer surface front and outer surface rear are all fixedly connected with several anti-skid protrusions 4, several anti-skid protrusions 4 are all arc structure, air bag 1 upper end is fixedly connected with hose 2, the end of hose 2 away from air bag 1 is inserted movably connected with dust cover 3, dust cover 3 diameter is greater than the diameter of hose 2, hose 2 is "U" shape structure, air bag 1 outer surface left part is fixedly connected with adhesive layer 5, adhesive layer 5 and several anti-skid protrusions 4 are all not contacted.

[0022] In the embodiment, several anti-skid protrusions 4 are vertically and equidistantly distributed;The height of hose 2 is greater than the height of air bag 1;Air bag 1 is hollow structure;Air bag 1 and hose 2 are communicated.

[0023] Through the above scheme: air bag 1 is pasted on the temporal side of the eye at any desired position, the opening of hose 2 is located on the conjunctival sac side, air bag 1 is lightly pinched, and the effusion is absorbed by air bag 1 and hose 2, so as to avoid the interference of effusion with the operation.

[0024] It should be noted that the utility model describes an eye surgery liquid drainage device of adhesive type, by setting hose 2 on the upper end of air bag 1, not only makes air bag 1 have the function of pressure device, but also gives it the role of storage space. In the use process, medical staff can easily paste air bag 1 on the temporal side of the eye at any desired position through the adhesive layer 5 on the left part of air bag 1, at this time, the opening of hose 2 is accurately positioned on the conjunctival sac side, which improves the efficiency of effusion discharge and reduces the possibility of effusion residue. During the operation, once the liquid accumulated in the conjunctival sac begins to affect the operator's operation vision and accuracy, the instrument nurse only needs to apply pressure to air bag 1, and these effusions can be quickly and smoothly sucked into and stored in the inside of air bag 1 through hose 2, which effectively avoids the delay or risk increase caused by effusion interference.
