Description

Technical Field

[0001] This utility model relates to the field of ophthalmic surgical instruments, and in particular to a medical illuminating scleral depressor. Background Technology

[0002] In today's society, rhegmatogenous retinal detachment (RRD) is a common blinding eye disease and a common serious complication among people with myopia. In recent years, with the increasing incidence of myopia, especially high myopia, the incidence of RRD has also been rising.

[0003] Scleral buckling is a classic surgical procedure for treating retinal tears (RRD), especially for children and adolescents with retinal detachment, where buckling surgery has a higher success rate and fewer complications. In scleral buckling, accurately locating the retinal tear and placing the scleral buckle in the ideal position is crucial for the repair of the tear.

[0004] Traditionally, retinal tear localization involves doctors using an ophthalmoscope to observe the retinal bulge caused by pressure applied to the sclera with a pressure handle to determine the location of the lesion. However, mastering this method requires a considerable amount of practice, and for inexperienced doctors, it is difficult to observe the lesion and the scleral bulge, thus making it difficult to accurately locate the retinal tear.

[0005] Therefore, an illuminated scleral indenter is needed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a medical illuminating scleral depressor that enables doctors to illuminate and depress the retina in the retinal tear area using optical fibers under a standard surgical microscope and a standard wide-angle observation system, thereby achieving visualization, localization, and marking of the retinal tear.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A medical scleral depressor with illumination, used in conjunction with an optical fiber device and a light source interface.

[0009] The medical illuminateable scleral depressor is made of translucent engineering plastic or alumina ceramic. It includes a main body, a head at one end of the main body, a tail at the other end of the main body, and an inner cavity extending from the tail to the head. The inner diameter of the inner cavity gradually increases from the head to the tail.

[0010] The optical fiber device includes a handle and a needle-shaped light-emitting probe located at one end of the handle. One end of the handle is fixedly connected to the tail end so that the needle-shaped light-emitting probe is fixed in the inner cavity.

[0011] The input end of the light source interface is connected to the optical fiber power supply, and the output end of the light source interface is connected to the needle-shaped light-emitting probe.

[0012] Furthermore, the tail and the handle are connected by a snap-fit ​​structure.

[0013] Furthermore, the inner wall of the tail section has a protruding annular rib, and the outer wall of the handle has a slot, with the annular rib engaging with the slot for positioning.

[0014] Furthermore, the tail and the handle are connected by an interference fit.

[0015] Furthermore, the head is spherical or arc-shaped.

[0016] Furthermore, the main body and the corresponding inner cavity are conical, and a wall thickness of 0.1~2mm is formed between the main body and the inner cavity.

[0017] This invention combines the functions of compression and illumination, providing better vision and lighting effects for eye surgery. It can accurately locate and mark retinal tears without the need for any intraocular instruments, special lens systems, other light sources, or scleral incision, thus improving the efficiency and accuracy of lesion location. It also helps inexperienced doctors quickly learn and master the technique of retinal tear location during scleral buckling surgery. Attached Figure Description

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figure 1 As shown, this utility model discloses a medical scleral indenter that can be illuminated, which is used in conjunction with an optical fiber device 2 and a light source interface 3.

[0030] The medical illuminated scleral depressor 1 is made of translucent engineering plastic or alumina ceramic, such as... Figures 2-4 As shown, the medical illuminated scleral depressor 1 includes a main body 101, a head 102 located at one end of the main body, a tail 103 located at the other end of the main body 101, and an inner cavity 104 extending from the tail 103 to the head 102. The inner diameter of the inner cavity 104 gradually increases from the head 102 to the tail 103.

[0031] The fiber optic device 2 includes a handle 201 and a needle-shaped light-emitting probe 202 located at one end of the handle 201. One end of the handle 201 is fixedly connected to the tail 103 so that the needle-shaped light-emitting probe 202 is fixed in the inner cavity 104.

[0032] The input end of the light source interface 3 is connected to the fiber optic power supply, and the output end of the light source interface 3 is connected to the needle-shaped light-emitting probe 202.

[0033] In one embodiment, the tail 103 and the handle 201 are connected by a snap-fit ​​structure, preferably, as shown below. Figure 3 As shown, the inner wall of the tail 103 has a protruding annular rib 107, and the outer wall of the handle 201 has a slot 203. The tail 103 and the handle 201 are fixedly connected by the cooperation of the annular rib 107 and the slot 203.

[0034] The main body 101 and the corresponding inner cavity 104 of the main body 101 have a conical structure. The cross-section of the other end of the main body 101 is curved outward, that is, the slope of the other end of the main body 101 with respect to the vertical direction gradually increases. The tail 103 has a cylindrical structure, and the outer diameter of the tail 103 matches the outer diameter of the other end of the main body 101.

[0035] The cylindrical structure of the tail 103, combined with the gradually increasing slope of the opening structure at the other end of the main body 101, makes it easy for the handle 201 to enter the tail 103, but not easy to enter the main body 101. When the handle 201 enters the tail 103 and is fixed, the tail 103 of the scleral pressure adapter 1 is subjected to axial and radial pressure, and the scleral pressure adapter 1 and the handle 201 will not separate, but the handle 201 can be pulled out by applying axial tension.

[0036] like Figure 3 As shown, the head 102 is spherical. Preferably, the diameter of the spherical head 102 is 1~2mm, the length of the tail 103 is 5~15mm, a wall thickness of 0.1~2.0mm is formed between the body 101 and the inner cavity 104, and the minimum diameter of the head 102 in the inner cavity 104 is 0.5~0.75mm.

[0037] In one embodiment, such as Figure 4 As shown, the head 102 is arc-shaped. Preferably, one side of the head 102 is a flat arc shape, and the other side of the head 102 is spherical.

[0038] like Figure 2 As shown, the tail portion 103 is provided with a plurality of strip grooves 108 along the axial direction. The strip grooves 108 are evenly distributed on the outer periphery of the tail portion 103. When the handle 201 enters the tail portion 103, the tail portion 103 can be appropriately expanded and deformed through the strip grooves 108, so that when the inner diameter of the tail portion 103 is smaller than the outer diameter of the handle 201, the tail portion 103 and the handle 201 can fit tightly together. In one embodiment, the tail portion 103 and the handle 201 are directly connected by an interference fit, without the need to provide annular ribs 107 and slots 203.

[0039] In this utility model of a medical scleral indenter 1 that can be illuminated, the head 102 can be stained in a single color or multiple colors, such as... Figure 5 As shown.

[0040] The operating method of the medical illuminating scleral indenter of this utility model includes the following steps:

[0041] Step 1) Place the medical illuminated scleral depressor 1 onto the fiber optic device 2, and fix it in place by engaging the tail 103 with the handle 201.

[0042] Step 2) Turn on the fiber optic power supply to power the needle-shaped light-emitting probe 202 through the light source interface 3, and the head 102 emits light;

[0043] Step 3) Bring head 102 close to the patient's eyeballs and open the patient's eyelids;

[0044] Step 4) Mark one side of the head 102 with a sterile marker, observe the location of the retinal tear with the uncolored side, rotate the head 102 180° to mark the location, and achieve precise localization of the retinal tear.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
