Technical Field
The utility model belongs to the technical field of medical instrument technique and specifically relates to a capsule membrane polishing injection head.
Background
Cataract is a common ophthalmological blindness-causing disease of the elderly population worldwide at present, and the incidence rate is also increased with the age. Over the years, people have conducted a great deal of research on the etiology and pathogenesis of cataract, and have also developed a great deal of medicine for treating cataract, but the medicine treatment can not effectively prevent or reverse lenticular opacity until now, and the surgical treatment is still the main treatment means of various cataracts. In recent years, the cataract surgery technology has been developed rapidly, especially the development and application of microsurgery and intraocular lens implantation technology, so that the cataract surgery is simpler and safer. However, with the increase of clinical data, it has been found that the occurrence of complications of cataract surgery, in which posterior capsule opacification is the most common complication after extracapsular cataract extraction (including phacoemulsification extraction), can greatly reduce the effectiveness of the surgery, and the incidence rate after adult surgery is 30% -50%, and in children is 100%. With the increasing progress of extracapsular cataract surgery, posterior capsular opacification has become an important factor affecting postoperative recovery of vision of patients.
At present, histopathology proves that proliferation and retrocapsular migration and metaplasia of residual anterior capsule or equatorial lens epithelial cells are the main reasons for occurrence of posterior capsular opacification, the proliferation capacity of the lens epithelial cells of children is high, so that the probability of occurrence of posterior capsular opacification is high, and the effective and simple method for preventing the occurrence of the posterior capsular opacification is to remove lens cortex and epithelial cells as far as possible in cataract surgery. At this stage, the common way of removing lens cortex and epithelial cells in surgery is: and polishing the capsular sac by using a capsular sac polisher.
The Chinese patent application: CN204698798U discloses a side-incision capsular polishing device, which is mainly used for cataract surgery. It includes a head, a neck and a handle, the head passes through the neck to be fixed in the one end of handle, and the neck is made by straight-bar section and circular arc section body coupling, straight-bar section and the coaxial fixed connection of handle, the upper portion diameter of straight-bar section diminishes gradually and the turn, connects the one end of circular arc section, the circular arc section other end tapering, tapering degressive and its terminal connection gradually the head, the head is the elliptical head, and its cross section is flat ellipse, and about the head be the even concave convex surface of ring surface for distributing, its roughness is in the line mark within range, and the surface does not have cutting edge, burr. Although the device can meet the requirements of the development of the existing cataract micro-incision operation, the device is not provided with a channel for injecting viscoelastic agent, so that the complexity of work is increased due to the fact that instruments are continuously replaced during injection, and the tissues in eyes are damaged or infected due to the fact that the instruments are repeatedly moved in and out.
