Description

Portable head position and support system for cataract blindness prevention operation

Technical Field

The invention relates to the technical field of medical auxiliary equipment, in particular to a portable head position and support system for cataract anti-blind surgery.

Background

In the surgical operation, an operation bag is often needed, the operation bag is usually composed of large wrapping cloth, an operation drape and a Meiya bag, and other operation accessories are additionally arranged according to the operation requirement. The operation drape is the core of the whole operation kit, and according to years of foreign clinical experience, the design concept and the production process of the operation drape better meet the actual requirements in the operation and more effectively protect patients and medical staff. The fabric has the main characteristics of good water resistance (water-resistant non-woven fabric), good water absorption (water-absorbing non-woven fabric), high hydrostatic pressure, good flexibility, less floc, no allergy, antistatic property, alcohol resistance, plasma resistance, oil stain resistance and the like.

Currently, in cataract blindness prevention surgery, a surgical drape is generally directly paved on the face and the chest of a patient, which has little influence on the general patient, but for some patients with basic diseases, the surgical drape influences the breathing of the patient. Therefore, in professional ophthalmologic hospitals (like Kenren hospitals) in certain first-line cities, an operating bed with a support special for eye surgery is arranged, and the condition that the breathing of a patient is influenced by attaching an operation drape to the face of the patient can be prevented; however, in most non-front-line hospitals and general comprehensive hospitals, the operating tables with the brackets are not popularized, so that most hospitals are matched with self-made bracket tools (such as tray brackets) for performing ophthalmic operations at present, the use is inconvenient, uniform standard requirements do not exist, and potential safety hazards exist.
