Problems solved by technology

However, the current posterior sclera pressurization is more cumbersome, very troublesome and inconvenient to use.
[0003] For example, the invention CN207708080U discloses a posterior sclera pressurizing device, but the device does not have a rebound function, and a light source module needs to be installed inside, which is cumbersome and inconvenient to use, and is difficult to manufacture and high in cost
Invention CN210056445U discloses a rebound-type posterior sclera pressurizing device. Although it has a rebound function, it is difficult for the device to accurately position the device on the eyeball, and the device rebounds using a push rod method, which requires precise control of strength , otherwise it is easy to accidentally injure the patient and cause optic nerve damage; at the same time, the push rod and the push rod sleeve must be taken out separately after the operation, which is inconvenient to use, and the sleeve is complicated to set up, the manufacturing process is cumbersome, and the process requirements are very strict, and the production cost is high

Embodiment 1

[0026] Example 1: Posterior Scleral Compression Device Example 1

[0027] as shown in the picture 1-4 As shown, the present invention is an improved rebound type posterior sclera pressurization device, which includes a hand-held end 1, and one end of the hand-held end 1 is fixedly connected with an arc-shaped pressurization end 2, the pressurizer The end of the pressure end 2 away from the hand-held end 1 is penetrated with a pressure ring 3 arranged in a quasi-circular shape. The two side walls of the hand-held end 1 are fixedly connected with suture fixing holes 4. Between the two side walls of the hand-held end A cross bar 5 is fixedly connected; a pressure rod 6 is detachably connected to the cross rod 5, and one end of the pressure rod 6 is detachably connected with the pressure ring 3, and the pressure rod 6 is respectively connected by a detachable connection device 7. Connected with the crossbar 5 and the pressure ring 3, the pressure rod 6 can be provided with a cert...

Embodiment 2

[0034] Example 2: Posterior Scleral Compression Device Example 2

[0035] The structural setting of Example 1 is basically the same, but the difference lies in the setting of the hand-held end 1, the hand-held end 1 is set to a plate-like structure or a mesh-like structure, so as to avoid damage to the sclera by the linear structure; the plate-like or There is a hole in the middle of the hand-held end 1 of the mesh structure, and the lower edge of the hole can replace the function of the cross bar 5 for the connection and rotation of the pressure rod 6 to realize the pressure on the pressure ring 3 .

Embodiment 3

[0036] Embodiment 3: method of use

[0037] According to the condition of the patient's eyes, select the pressure rod 6 of suitable size, and select the connecting device parts on the suitable pressure rod, and connect the pressure rod 6 to the cross bar 5 and the pressure ring 3. At this time, the pressure rod 6 Apply pressure to the pressure ring 3, push the pressure ring 3 backward for a certain distance (such as 2-8mm, etc.), and maintain the pressure on the pressure ring 3.

[0038] When in use, firstly open the conjunctiva and fascia of the patient’s temporal eye, extend the pressurized end 2 under the fascia and extend back along the sclera wall to below the macular area, fix the hand-held end 1 by suturing the fixing hole 4, and then insert the The pressure rod 6 is separated from the hand-held end 1, the cross bar 5 and the pressure ring 3 and taken out; the pressure ring 3 rebounds and presses against the macula to exert a pressure effect.

Abstract

The invention discloses an improved springback-type posterior sclera buckling device. The improved springback-type posterior sclera buckling device comprises a handheld end, a buckling end, a bucklingring and a buckling rod, wherein the buckling ring is in the buckling end. The device disclosed by the invention can be used for treating high myopia with posterior staphylom, macular holes, macularretinoschisis and the like, can also be used for delaying the growth of high myopia eye axis, can apply pressure to the buckling ring only through simple operation of the buckling rod, and cannot cause eye injury to a patient. Meanwhile, the device disclosed by the invention is simpler in structure, more convenient to operate, low in manufacturing difficulty, easy to industrialize, and low in manufacturing cost, and can be better accepted by a wide range of patients.

Description

technical field [0001] The invention relates to a posterior sclera pressure device, in particular to an improved rebound type posterior sclera pressure device, which belongs to the technical field of medical equipment. Background technique [0002] Posterior scleral compression is usually used for the treatment of posterior staphyloma, macular hole, macular schisis, etc. in high myopia, and provides an important means for the treatment of fundus complications in high myopia; axis of growth. However, the current posterior sclera pressurization is relatively cumbersome, very cumbersome and inconvenient to use. [0003] For example, the invention CN207708080U discloses a posterior sclera pressurizing device, but the device does not have a rebound function, and a light source module needs to be installed inside, which is cumbersome and inconvenient to use, and is difficult to manufacture and high in cost. Invention CN210056445U discloses a rebound-type posterior sclera pressur...
