Description

Technical Field

[0001] The utility model relates to the technical field of surgical auxiliary equipment, in particular to an eye surgery implantation device. Background Art

[0002] High myopia patients develop myopic traction maculopathy (MTM) due to the continuous growth of the eye axis, which in turn leads to a series of pathological changes such as vitreous opacity and liquefaction, as well as choroidal atrophy, retinal holes, macular schisis and retinal detachment. These changes can seriously impair visual function and may even lead to permanent blindness.

[0003] Macular buckling surgery is an effective treatment for MTM. For most patients with high myopia, it has advantages over other treatments, such as a low risk of recurrence and fewer postoperative complications. Furthermore, with the advancement of medical technology and materials science, the success rate of macular buckling surgery has significantly increased, making it the primary surgical method for treating MTM.

[0004] However, the macular buckle used in the prior art is mostly made of flexible materials. The material of the macular buckle is relatively soft and cannot effectively squeeze and support the eyeball after being implanted into the eyeball.

[0005] The most common technique for macular buckling surgery is to sew the buckle to the side of the patient's eyeball. To ensure that the buckle is stably fixed to the patient's eyeball, the buckle used in the prior art is equipped with a mounting strip at the suture portion between the buckle and the eyeball. The mounting strip is provided with a plurality of suture holes, which allow the suture to be better fixed to the patient's eyeball.

[0006] However, after the buckle of the prior art is implanted in the patient's eyeball, the mounting strip of the buckle is easily exposed to the air due to the rotation of the patient's eyeball. The mounting strip is easily oxidized and deteriorated after contact with the outside air. The deteriorated mounting strip may cause damage to the patient's eye after contact with the eyeball. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art buckle straps, such as weak squeezing and supporting effect and the buckle strap mounting strips being easily exposed to the air when driven by the eyeball, the present utility model provides an eye surgery implant device.

[0008] The technical solution of the present utility model is: an eye surgical implant device, comprising an external wrapping layer and an internal support frame; the external wrapping layer is provided with a hollow cavity without an opening, the external wrapping layer is connected to the internal support frame, and the internal support frame is located in the hollow cavity of the external wrapping layer, and the external wrapping layer fully wraps the internal support frame; wherein, the external wrapping layer includes a main body, a pressing head, a support bar and a suture ring; a pressing head is provided at the front of the main body, and the pressing head is set according to the size of the patient's lesion; two support bars distributed on the left and right are provided at the rear of the main body; a suture ring is provided at the end of each support bar away from the main body.

[0009] As a preferred technical solution of the utility model, it also includes a fixing ring; two fixing rings distributed on the left and right are arranged in the middle of the main body.

[0010] As a preferred technical solution of the present invention, there is an angle between the two branches, and the angle is set according to the actual curvature of the patient's eyeball.

[0011] As a preferred technical solution of the present invention, the internal support frame is made of metal material.

[0012] As a preferred technical solution of the present invention, all edges of the internal support frame are chamfered.

[0013] Beneficial effects: The utility model, through the cooperation of the outer wrapping layer and the inner support frame, enables the device to better fit the patient's eyeball during surgery, allowing the surgeon to perform the surgery more conveniently;

[0014] Furthermore, due to the internal support frame, the device is less likely to deform when the patient's eyeball rotates, and has a stronger support force for squeezing the patient's lesion after surgery.

[0015] The setting of the fixing ring avoids the problem of the buckle slipping or the serrated part of the buckle affecting the doctor's operation in the prior art;

[0016] By setting the angle, the risk of the support bar contacting the outside world is greatly reduced, and when the patient moves the eyeball, the support bar is not easily exposed, which also makes the patient's eyeball more beautiful in daily life. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0026] Example 1

[0027] An eye surgery implant device, such as Figure 1-7 As shown, it includes an outer wrapping layer 101 and an inner support frame 102; the outer wrapping layer 101 is provided with a hollow cavity without an opening, the outer wrapping layer 101 is connected to the inner support frame 102, and the inner support frame 102 is located in the hollow cavity of the outer wrapping layer 101, and the outer wrapping layer 101 fully wraps the inner support frame 102;

[0028] Among them, the outer wrapping layer 101 includes a main body 1, a pressing head 2, a support 4 and a suture ring 5; a pressing head 2 is provided at the front of the main body 1, and the pressing head 2 is set according to the size of the patient's lesion; two supports 4 distributed on the left and right are provided at the rear of the main body 1; a suture ring 5 is provided at the end of each support 4 away from the main body 1.

[0029] It also includes a fixing ring 3; two fixing rings 3 distributed on the left and right are provided in the middle of the main body 1, and the fixing rings 3 are used to further fix the device.

[0030] There is an included angle 6 between the two branches 4, and the angle 6 is set according to the actual curvature of the patient's eyeball.

[0031] The internal support frame 102 is made of metal material. The metal setting of the internal support frame 102 enables the device to have better squeezing and supporting force on the lesion.

[0032] All edges of the internal support frame 102 are chamfered to prevent the internal support frame 102 from piercing the outer wrapping layer 101 in an emergency and causing serious damage to the patient's eyeball.

[0033] Before implanting the device into the patient's eye for macular buckling surgery, the device is bent into a Figure 2 The outer wrapping layer 101 can be bent without external force under the action of the internal support frame 102, so that the device can better fit the patient's eyeball during surgery, allowing the surgeon to perform surgery more conveniently. Later, during the operation, the doctor will aim the pressing head 2 at the patient's lesion site, so that the lesion can be initially squeezed and supported. The internal support frame 102 is made of metal, and the squeezing and supporting force on the patient's lesion is stronger after the operation. Under the action of the internal support frame 102, the device is less likely to be deformed when the patient's eyeball rotates.

[0034] Afterwards Figure 3 As shown, the suture ring 5 of the device is adjusted to the appropriate position of the patient's eyeball, and the doctor uses sutures to fix the suture ring 5 on the patient's eyeball, thus completing the basic fixation of the operation;

[0035] like Figure 4 As shown, since the buckle of the prior art (i.e., the example buckle 8 in the figure) is mostly set as a long strip, after basic fixation, the middle part of the buckle of the prior art is not fixed. Since the patient's eyeball will move daily after the operation, it will squeeze the buckle, causing the middle part of the buckle to arch, causing discomfort to the patient's eyeball, and even causing serious damage to the patient's eye. Therefore, during the operation, the doctor will use the example fixing line 9 to fix the middle part of the buckle and the patient's eyeball. However, since the middle part of the buckle of the prior art is mostly smooth and easy to slide, the example fixing line 9 cannot effectively fix the buckle on the patient's eyeball.

[0036] In order to avoid the problem of the middle part of the buckle slipping, some existing buckles are provided with a serration in the middle part to prevent the buckle from moving. However, the provision of the serration greatly affects the doctor's suture fixation of the middle part of the buckle, because the doctor generally uses special surgical tweezers to clamp the surgical needle and fix the buckle with the suture through the surgical needle. The clamping part of the surgical tweezers is generally very small. The serration of the buckle greatly affects the work of the surgical tweezers during actual surgery, thereby affecting the quality of the doctor's surgery.

[0037] Therefore, the present device is provided with two fixing rings 3, and the present device can be fixed by the two fixing rings 3 when the doctor is performing the operation, thus avoiding the problem in the prior art that the buckle may slip or the buckle serrations may affect the doctor's operation, and the provision of the fixing ring 3 makes the contact area between the outer wrapping layer 101 and the inner support frame 102 larger, and the outer wrapping layer 101 and the inner support frame 102 can be more tightly adhered, so that the present device is less likely to have a problem during production because the contact surface between the outer wrapping layer 101 and the inner support frame 102 is too small, resulting in a gap between the outer wrapping layer 101 and the inner support frame 102, thereby causing bulging and making it impossible to use normally, thereby improving the yield rate of the production of the present device;

[0038] Furthermore, because the prior art buckle is fixed in surgery, the tail Figure 4 The figure is closer to the external environment, and the buckle tail mounting strip of the prior art is as shown. Figure 4 The arrangement is shown as straight. If the demonstration eyeball 7 is rotated clockwise from a top-down perspective, the tail mounting strip of the conventional buckle strap will extend beyond the exemplary eye socket 10 and come into contact with the outside air. The mounting strip is susceptible to oxidation and deterioration upon contact with the outside air. The deteriorated mounting strip may cause damage to the patient's eye upon contact with the eyeball.

[0039] Therefore, the two branches 4 of the device are provided with an angle 6. Due to the setting of the angle 6, the two branches 4 are farther away from the vertical part of the example eye socket 10 (the vertical part of the example eye socket 10 here is the edge of the eye socket in reality). In this way, when the patient rotates the eyeball, the risk of the branches 4 contacting the outside world is greatly reduced. In addition, when the patient rotates the eyeball, the branches 4 are not easily exposed, which also makes the patient's eyeball more beautiful in daily life.

[0040] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
