Abstract
Description
Technical Field
[0001] The utility model relates to a patch used for posterior segment surgery of the eye, belonging to the technical field of surgical instruments. Background Art
[0002] Posterior segment surgery refers to surgery involving diseases of the posterior segment of the eye, such as the vitreous body and retina, including proliferative diabetic retinopathy, epiretinal membrane, macular hole, vitrectomy and retinal detachment. Posterior segment vitrectomy is difficult, takes a long time, and requires high technical skills, and is considered the most delicate and difficult surgery in ophthalmology.
[0003] The operation requires three scleral incisions, which are selected in the superior temporal quadrant, inferior temporal quadrant, and superior nasal quadrant respectively. An ophthalmic puncture knife is used to make puncture incisions at three puncture points 4m away from the limbus of the cornea and sclera (3.5mm for aphakic eyes). The blade is inserted 5mm deep, and a short perfusion needle is inserted into the lower incision and ligated to maintain stable intraocular pressure. The surgical instruments enter and exit through these three perfusion channels. When no instruments enter, the perfusion port is blocked with a scleral plug. Due to the pressure of the perfusion fluid, when the scleral plug is removed, the vitreous body or intraocular perfusion fluid will spray out from the perfusion port.
[0004] During surgery, the perfusion pressure rises to 50-60 mmHg when the liquid flows, and drops to 30-45 mmHg when using intraocular forceps, membrane hooks, etc. in a static state. During the operation, intraocular instruments enter and exit the perfusion port according to the surgical steps. During this period, the perfusion fluid will be sprayed out from the perfusion port. Due to the size of the perfusion pressure, the perfusion fluid will be sprayed to different surgical areas; when continuous vitreous cavity irrigation is required, for example, silicone oil removal surgery, vitreous cavity irrigation is required to reduce silicone oil residue, and the amount of liquid sprayed from the perfusion port is more; there are currently no corresponding measures for the above situations, and most of them rely on assistant doctors to cover with their hands. The problem is that the sprayed perfusion fluid wets the surgical sheet around the eye. For ophthalmic surgeries where the head and face are covered, on the one hand, it poses a risk of contamination of the surgical area. On the other hand, the wet surgical sheet covers the patient's mouth and nose, affecting their breathing; secondly, due to the perfusion pressure, the sprayed water column will spray onto the operator outside the surgical area; in addition, the assistant needs to free up one hand to cover the sprayed liquid, which affects his two-handed operation and affects the coordination of surgical operations. Summary of the invention
[0005] The purpose of the utility model is to provide a patch for posterior segment surgery in order to solve the problems of the injection fluid and vitreous body contaminating the surgical area, affecting the ventilation of the patient's mouth and nose and contaminating the operator.

[0008] The liquid-conducting film comprises a liquid-conducting film body, which is a waterproof plastic film. A support strip is provided at the edge of the waterproof plastic film. A first water-conducting groove is provided from the middle to the edge of the waterproof plastic film. The edge port of the first water-conducting groove is connected to a second water-conducting groove.

DETAILED DESCRIPTION
[0018] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.
[0019] Example
[0020] This embodiment provides a patch for posterior segment surgery, such as Figures 1-2 As shown, it includes a fluid collection bag 1 for collecting fluid, a self-adhesive eye patch 2 for protecting the eyes, and a fluid guide film 3 for blocking water and guiding the fluid to flow into the fluid collection bag.
[0021] Among them, the main body of the fluid accumulation bag 1 is a waterproof bag made of medical polymer material, and a bag opening strip 1-2 is provided on one side of the bag opening 1-1 of the fluid accumulation bag. The bag opening strip 1-2 is a metal strip wrapped with a plastic layer. This material has certain plasticity, light material, and supporting force, is easy to fold, has good adhesion, and has deformable and supporting functions; the main body of the self-adhesive eye patch 2 is a self-adhesive medical thin patch, which is semicircular, and the arc-shaped edge of the self-adhesive eye patch 2 is provided with a water-conducting strip 2-1 near the edge, so that the arc-shaped edge of the self-adhesive eye patch is raised relative to the water-conducting strip 2-1 (that is, the edge surface and the edge pressure are close to each other). The strip is in a non-horizontal position, forming an angle of >0 degrees), which can play the role of water blocking and water guiding. The straight edge of the self-adhesive eye patch 2 is provided with a connecting strip 2-2, which is fixedly connected to the other side of the bag opening 1-1 of the effusion bag, that is, the bag opening can be opened through the bag opening strip 1-2 and the connecting strip 2-2, which is convenient for collecting liquid; the liquid guiding film 3 includes a liquid guiding film body 3-1, which is a waterproof plastic film made of medical polymer material, and is provided with support strips 3-2 on the edges. The support strips are used to maintain the liquid guiding film body in a certain shape (for example, it can be square or round) and open, and the center to the edge forms a The first water guide groove 3-3 has a gradually narrowing water guide channel near the edge of the liquid guide film body 3-1. The water guide groove 3-3 is in the shape of a gourd or a net bag. The manufacturing method can be to form the first water guide groove 3-3 by pre-shaping the waterproof plastic film or by adding a support strip. The outer edge port of the first water guide groove 3-3 is connected to the second water guide groove 3-4. The second water guide groove 3-4 is made of a metal sheet wrapped with a plastic layer, which can guide the liquid to flow along the groove. The end of the second water guide groove 3-4 is provided with a clamping connection for the bag opening strip 1-2 or the eye. When the slot 3-5 of the edge strip 2-1 of the eye patch is used, the ejected liquid can be collected into the effusion bag 1 through the drainage of the liquid guide film 3 by snapping the slot 3-5 onto the bag opening strip 1-2 or the edge strip 2-1 of the eye patch according to the direction of the ejected liquid. When the slot 3-5 is snapped onto the edge strip 2-1 of the eye patch, the liquid flows along the edge strip within the edge of the eye patch due to the protrusion of the edge of the eye patch and is finally collected into the effusion bag 1. The angle can be moved or adjusted according to the needs of the surgical operation. The deformable and easy-to-fold strip can better drain the liquid and ensure that the surgical field of view is not affected. When not in use, the liquid guide film 3 can be laid flat along the bag body or the patch part without affecting the surgical operation.
