Description

Technical Field

[0001] This utility model belongs to the field of medical surgical instrument technology, and in particular relates to a scleral circumcision band and a scleral circumcision device. Background Technology

[0002] Scleral ligation is an important surgical procedure for treating retinal detachment and other fundus diseases. Its principle involves implanting a ring-shaped band around the entire circumference of the eye to create mechanical pressure, causing the sclera to retract and form an artificial ora serrata. This procedure effectively reduces the vitreous cavity volume, establishes a uniform pressure distribution around the eyeball, thereby relieving the pathological traction between the vitreous and retina and promoting retinal repositioning.

[0003] Currently, scleral ligatures used clinically are mainly made of biocompatible materials such as silicone or polyester. These materials have good flexibility and elasticity, can precisely match the curvature of the eyeball, and provide continuous support. Standard surgical procedures require placing the ligature on the scleral surface at the equator or posterior pole of the eyeball and fixing it with sutures. However, this technique has certain limitations. On the one hand, during the operation, the surgeon needs to cut the scleral ligature according to the patient's specific condition and then suture the cut scleral ligature. This makes the scleral ligature suturing and fixing process highly demanding on the surgeon's skills. Improper operation may lead to complications such as scleral perforation or bleeding. On the other hand, it is necessary to precisely control the pressure of the ligature on the eyeball wall during the operation, which is crucial to ensuring the retinal reattachment effect. These technical difficulties limit the safety and predictability of the surgery to some extent.

[0004] Therefore, there is an urgent need for a scleral circumcision band and scleral circumcision device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a scleral ligation band and scleral ligation device that does not require sutures and whose pressure on the eyeball is adjustable, significantly reducing the requirements for doctors' operating skills and the possibility of scleral perforation and bleeding, and improving the safety and predictability of the operation.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On one hand, a scleral bead band is provided, including a band body, one end of which is provided with an elastic clip, and the other end of which is provided with multiple clip holes, which are spaced apart along the extension direction of the band body; the elastic clip includes a connected limiting part and a snap-fit ​​part, and the limiting part is located on the side of the snap-fit ​​part away from the band body, the cross-sectional width of the limiting part is greater than the cross-sectional width of the snap-fit ​​part, the snap-fit ​​part can pass through any clip hole and contact the corresponding clip hole wall, and the limiting part can pass through the clip hole to the side of the band body away from the eyeball and contact the side wall of the band body away from the eyeball.

[0008] Optionally, the elastic clip also includes a transition portion, one end of which is connected to the limiting portion and the other end of which is connected to the snap-fit ​​portion, and the cross-sectional width of the transition portion increases from the snap-fit ​​portion to the limiting portion.

[0009] Optionally, the cross-sectional shape of the snap-fit ​​part and the snap-hole is rectangular, and the cross-sectional shape of the limiting part is rectangular or circular.

[0010] Optionally, the cross-sectional shape of the snap-fit ​​part and the snap-hole is circular, and the cross-sectional shape of the limiting part is rectangular or circular.

[0011] Optionally, the flexible clip is an inverted embossed structure made of silicone.

[0012] Optionally, the cable tie body is a strip structure made of silicone.

[0013] On the other hand, a scleral ligation device is provided, including an elastic annular band and the aforementioned scleral ligation band. The elastic annular band can be fitted onto the eyeball, and the inner wall of the elastic annular band can fit against the eyeball wall. The ligation band body of the scleral ligation band is engaged with the elastic annular band.

[0014] Optionally, the elastic annular band is provided with a mounting groove extending circumferentially thereon, and the main body of the scleral band tie is engaged in the mounting groove.

[0015] Optionally, the elastic ring band is curved along its width direction and is symmetrically curved about the thickness direction of the cable tie body, and the distance between the mounting groove and both ends of the elastic ring band in the width direction is the same.

[0016] Optionally, the elastic annular belt is curved along its width direction, and the curvature of one end of the elastic annular belt along its width direction is greater than the curvature of the other end, and the distance between the mounting groove and the two ends of the elastic annular belt along its width direction is different.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention provides a scleral circumference ligation band and a scleral circumference ligation device. The locking part can be inserted into any locking hole, allowing the two ends of the ligation band body to be connected and form a ring structure. Furthermore, the circumference of the ring structure can be adjusted by adjusting the locking hole where the locking part is located, without the need to cut the ligation band body. This allows for adjustment of intraocular pressure by the ligation band body, improving the predictability of the surgery. Connecting the two ends of the ligation band body is completed simply by inserting the locking part through the locking hole, which is not only quick and easy to operate but also eliminates the need for suturing the ligation band body, making it more convenient for use in the surgical field. This significantly reduces the skill requirements for the surgeon and the possibility of scleral perforation and bleeding, thus improving the safety of the surgery. When the locking part is inserted into the locking hole, the contact between the locking part and the hole wall helps increase the friction between them, reducing the range of movement of the locking part within the hole. Simultaneously, the limiting part, connected to the locking part and with a cross-sectional width greater than the locking part, is located on the side of the cable tie body away from the eyeball and contacts the side wall of that side. This limiting part further restricts the movement of the locking part within the hole and prevents it from detaching, helping to ensure the secure installation of the cable tie body on the eyeball and the stability of the pressure applied to the eyeball. The elastic ring band has a certain degree of elasticity, allowing it to be easily fitted onto the eyeball by pulling, improving the ease of installation. The scleral ligature can be secured to the elastic ring band, which not only stably confines the scleral ligature to its current position, improving the stability of the scleral ligature on the eyeball, but also prevents the scleral ligature from directly contacting the patient's eyeball when the locking part is passed through the locking hole, further improving the safety of the operation and reducing the requirements for the doctor's operating skills.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figures 1 to 3 As shown, this embodiment provides a scleral ligation band that does not require sutures and whose pressure on the eyeball is adjustable, significantly reducing the skill requirements for doctors and the possibility of scleral perforation and bleeding, thus improving the safety and predictability of the surgery.

[0033] See Figure 1 and Figure 2The scleral bead band includes a band body 1, one end of which is provided with an elastic clip 12, and the other end of which is provided with a plurality of clip holes 11, which are arranged at intervals along the extension direction of the band body 1. The elastic clip 12 includes a connected limiting part 121 and a snap-fit ​​part 122, and the limiting part 121 is located on the side of the snap-fit ​​part 122 away from the band body 1. The cross-sectional width of the limiting part 121 is greater than the cross-sectional width of the snap-fit ​​part 122. The snap-fit ​​part 122 can pass through any clip hole 11 and contact the corresponding clip hole 11 wall. The limiting part 121 can pass through the clip hole 11 to the side of the band body 1 away from the eyeball and contact the side wall of the band body 1 away from the eyeball.

[0034] The scleral ligature provided in this embodiment has a locking part 122 that can be inserted into any locking hole 11, allowing the two ends of the ligature body 1 to be connected and form a ring structure. Furthermore, the circumference of the ring structure can be adjusted by adjusting the locking hole 11 where the locking part 122 is located, without the need to cut the ligature body 1. This allows for adjustment of intraocular pressure by the ligature body 1, improving the predictability of the surgery. Connecting the two ends of the ligature body 1 by simply inserting the locking part 122 through the locking hole 11 is not only quick and easy to operate, but also eliminates the need for suturing the ligature body 1, making it more convenient for use in the surgical field. This significantly reduces the skill requirements for the surgeon and the possibility of scleral perforation and bleeding, thus improving the safety of the surgery. When the latching part 122 passes through the latching hole 11, the contact between the latching part 122 and the hole wall of the latching hole 11 helps to increase the friction between the latching part 122 and the hole wall of the latching hole 11, and reduces the range of movement of the latching part 122 within the latching hole 11. At the same time, the limiting part 121, which is connected to the latching part 122 and has a cross-sectional width greater than the latching part 122, is located on the side of the cable tie body 1 away from the eyeball and contacts the side wall of the cable tie body 1 on that side. The limiting part 121 will further restrict the movement of the latching part 122 within the latching hole 11 and prevent the latching part 122 from detaching from the latching hole 11, which helps to ensure the firmness of the cable tie body 1 after it is installed on the eyeball and the stability of the pressure value applied by the cable tie body 1 to the eyeball.

[0035] Specifically, when the elastic clip 12 is connected to the clip hole 11, the limiting part 121 and the snap-fit ​​part 122 pass through the clip hole 11 in sequence. Because the cable tie body 1 has a certain degree of elasticity, the clip hole 11 can deform to a certain extent, allowing the limiting part 121, whose cross-sectional width is greater than that of the snap-fit ​​part 122, to pass smoothly through the clip hole 11 and contact the side of the cable tie body 1 opposite to the eyeball.

[0036] Optionally, see Figure 2 and Figure 3The elastic clip 12 also includes a transition portion 123, one end of which is connected to the limiting portion 121, and the other end is connected to the locking portion 122. The cross-sectional width of the transition portion 123 increases from the locking portion 122 to the limiting portion 121. This arrangement allows the cross-sectional width of the elastic clip 12 to smoothly transition from the locking portion 122 to the limiting portion 121, enabling the limiting portion 121 to move smoothly through the locking hole 11 to the side of the cable tie body 1 away from the eyeball. This prevents the limiting portion 121 from being stuck by the hole wall of the locking hole 11, improving the efficiency of the connection between the elastic clip 12 and the hole wall of the locking hole 11, and facilitating the smooth operation of connecting the two ends of the cable tie body 1.

[0037] See Figure 2 and Figure 3 The cross-sectional width of the transition portion 123 transitions in an arc shape from the snap-fit ​​portion 122 to the limiting portion 121, which helps to further improve the smoothness of the limiting portion 121 passing through the snap hole 11.

[0038] In an optional embodiment, both the locking portion 122 and the locking hole 11 have rectangular cross-sectional shapes, while the limiting portion 121 has a rectangular or circular cross-sectional shape. The rectangular cross-sectional shapes of both the locking portion 122 and the locking hole 11 prevent the locking portion 122 from rotating within the locking hole 11, further improving its stability and the stability of the ligature body 1 on the eyeball after surgery. When the limiting portion 121 has a rectangular cross-sectional shape, it matches the locking hole 11, allowing it to pass through the locking hole 11 only at a specific angle. This helps prevent relative twisting at both ends of the ligature body 1, ensuring the accuracy of the ligature body 1's installation on the eyeball. When the cross-sectional shape of the limiting part 121 is circular, there is no directional restriction when the limiting part 121 passes through the through hole. That is, the limiting part 121 can pass through the through hole without aligning it with the locking hole 11, which reduces the difficulty of operation and improves the efficiency of connecting the two ends of the cable tie body 1.

[0039] In another alternative embodiment, see [link to relevant documentation] Figure 2 Both the snap-fit ​​portion 122 and the snap-fit ​​hole 11 have circular cross-sectional shapes, while the limiting portion 121 has a rectangular or circular cross-sectional shape. The circular cross-sectional shapes of both the snap-fit ​​portion 122 and the snap-fit ​​hole 11 eliminate the need to adjust the angle of the snap-fit ​​portion 122 when inserting it into the snap-fit ​​hole 11, facilitating a quick connection between the snap-fit ​​portion 122 and the snap-fit ​​hole 11 and improving the efficiency of connecting the two ends of the cable tie body 1. Furthermore, the circular cross-sectional shape of the snap-fit ​​hole 11 allows the limiting portion 121 to pass quickly through the snap-fit ​​hole 11 regardless of whether its cross-sectional shape is rectangular or circular, eliminating the need to adjust its angle and reducing the difficulty of connecting the two ends of the cable tie body 1, thus improving the efficiency of connecting the two ends of the cable tie body 1.

[0040] For example, see Figure 2 The cross-sectional shape of the limiting part 121, the snap-fit ​​part 122 and the snap-hole 11 are all circular.

[0041] Optionally, see Figure 2 and Figure 3 The elastic clip 12 is an inverted convex structure made of silicone, which has excellent elasticity and durability. It not only ensures that the limiting part 121 will not be damaged when passing through the clip hole 11, but also allows the clip part 122 to have a certain friction when it contacts the wall of the clip hole 11, thus preventing the clip part 122 from moving within the clip hole 11.

[0042] See Figure 3 The limiting part 121 is located at the top of the inverted convex elastic clip 12, and the snap-fit ​​part 122 is at the bottom of the inverted convex elastic clip 12.

[0043] Optionally, see Figure 2 The main body of the cable tie 1 is a strip structure made of silicone, which has excellent elasticity and durability, and can adapt to different eyeball sizes and shapes, providing stable support and pressure for the retina.

[0044] Example 2

[0045] like Figures 4 to 6 As shown, this embodiment provides a scleral ligation device, including an elastic annular band 2 and a scleral ligation band from Embodiment 1. The elastic annular band 2 can be fitted onto the eyeball, and the inner wall of the elastic annular band 2 can fit against the eyeball wall. The ligation band body 1 of the scleral ligation band is engaged with the elastic annular band 2. The elastic annular band 2 has a certain degree of elasticity, allowing it to be fitted onto the eyeball by pulling, thus improving the ease of installation. The scleral ligation band can be engaged with the elastic annular band 2, which not only stably confines the scleral ligation band to its current position, improving the stability of the scleral ligation on the eyeball, but also prevents the scleral ligation band from directly contacting the patient's eyeball when the engaging part 122 passes through the engaging hole 11, further improving the safety of the surgery and reducing the requirements for the surgeon's operating skills.

[0046] For example, the elastic ring band 2 is a ring structure made of silicone, which has excellent elasticity and durability, allowing the elastic ring band 2 to be fitted onto the eyeball.

[0047] Optionally, see Figure 4 The elastic annular band 2 is provided with a mounting groove 21 extending circumferentially therein, and the main body 1 of the scleral bead band is engaged in the mounting groove 21. The groove wall of the mounting groove 21 can restrict the movement of the main body 1 of the band to ensure the stability of the main body 1 of the band on the eyeball.

[0048] In this embodiment, see Figure 4 and Figure 5 The elastic annular belt 2 along its width direction ( Figure 5 The elastic ring band 2 is curved in the X direction and is about the thickness direction of the cable tie body 1. Figure 5 The elastic annular band 2 is symmetrically curved in the Y direction, and the mounting groove 21 is equidistant from both ends of the elastic annular band 2 in the width direction, meaning that the mounting groove 21 is located at the middle position of the elastic annular band 2 along its width direction. This configuration makes the elastic annular band 2 a symmetrical structure, suitable for the equatorial region of the patient's eyeball.

[0049] In other embodiments, see Figure 4 and Figure 5 The elastic annular band 2 is curved along its width direction, and the curvature of one end of the elastic annular band 2 along its width direction is greater than that of the other end. The mounting groove 21 is at different distances from the two ends of the elastic annular band 2 along its width direction. This configuration makes the elastic annular band 2 an asymmetrical structure, which can be applied to other parts of the patient's eyeball except for the equator.

[0050] During the surgery, staff can select different types of elastic ring bands 2 according to the location of the scleral slit in the patient's eyeball to ensure that the inner wall of the elastic ring band 2 can always be completely in contact with the patient's eyeball wall, so as to ensure the pressure effect of the scleral ligation band on the patient's eyeball.

[0051] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
