Embodiment 1

[0028] A posterior sclera quantitative compression block, such as figure 1 As shown, it includes an implant body 1 and an implant handle 2, wherein the implant body 1 is used for implanting in the human eye for external pressure on the sclera, and the implant body 1 is made of flexible material and flexible silicone, which has elastic deformation Its interior is hollow, and one end of the implant handle 2 is fixedly connected with the implant body 1. The implant handle 2 is provided with a water conduit 3, and the water conduit 3 is arranged along the implant handle 2, and one end of the implant handle is connected to the implant body. The other end extends to the end of the implant handle 2 away from the implant body 1, and the end of the water channel 3 away from the implant body 1 is closed. The water channel 3 can be used to inject sterilized physiological saline, and the syringe needle After being inserted into the water channel 3 and injected, the sterilized physiologica...

Embodiment 2

[0034] This embodiment discloses a method for using the posterior sclera quantitative pressure block in Embodiment 1, comprising the following steps:

[0035] Step 1. Connect the part of the light guide wire 4 outside the implant handle 2 to the light source, so as to illuminate the implant body 1;

[0036] Step 2. Implanting the posterior sclera quantitative compression block to the position outside the scleral staphyloma;

[0037] Step 3. Inject normal saline into the water conduit 3 under direct vision during the intraoperative optical tomography coherence inspection. Insert the height of the main body 1, and stop the injection when the propped up height of the implanted main body 1 reaches the anatomical reset of the retina;

[0038] Step 4. Pull out the light guide wire 4. During the extraction process, the implant handle 2 can be clamped and fixed by surgical forceps, and the light guide wire 4 can be pulled out by another surgical forceps;

[0039] Step 5, suturing an...

Abstract

The embodiments of the invention disclose a posterior scleral quantitative pressure block and a using method thereof, and belong to the technical field of ophthalmic surgical treatment appliances. According to the technical scheme key point, the posterior scleral quantitative pressure block comprises an implant body and an implant handle, one end of the implant handle is connected to the implant body, the implant body is of a flexible hollow structure, and a water flow pipeline is disposed in the implant handle, and the water flow pipeline is disposed in the length of the implant handle, one end of the water flow pipeline communicates with the implant body, the other end of the water flow pipeline extends to the end, away from the implant body, of the implant handle, and the posterior scleral quantitative pressure block and the using method thereof have the advantage of being able to perform sterile saline solution injection through the pipeline during the operation for quantitative pressure.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of ophthalmic surgical treatment appliances, in particular to a posterior sclera quantitative pressurization block and its usage method. Background technique [0002] With the significant increase in the prevalence of high myopia in my country in recent years, epidemiological studies have shown that there are as many as 29 million to 30.4 million high myopia patients, and fundus lesions caused by high myopia have become one of the important diseases of irreversible blindness. Among them, traction maculopathy caused by high myopia mainly includes three types: foveal retinoschisis, foveal retinal detachment, and macular hole. It is a group of blinding diseases that seriously affect the visual function of patients. [0003] At present, there are several mainstream options for clinical treatment of traction maculopathy, including macular buckle surgery (macularbuckle), vitrectomy (parsp...
