Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic surgery, in particular to an ophthalmic surgery auxiliary bracket. Background Art

[0002] Ophthalmic surgery refers to surgery on the eyes, which is a type of surgery specifically performed for eye diseases. Ophthalmic surgery requires a very high level of precision and is divided into level one, level two, level three, and level four surgeries. Level one surgery is relatively simple, with low technical difficulty and low risk. Level two surgery is a medium-level surgery with medium risk and average technical difficulty. Level three and level four surgeries have high risks, high technical difficulty, and complex surgical procedures.

[0003] During ophthalmic surgery, a sterile surgical towel will be covered on the patient's face. In order to prevent the surgical towel from directly covering the patient's face, a bracket will be placed under the surgical towel and supply oxygen to it, thereby avoiding breathing difficulties and suffocation for the patient and making the operation safer.

[0004] When using the stent, due to the different ages and body shapes of patients, the distance between the patient's mouth and nose and the oxygen inlet is different, so the oxygen inlet cannot be in the most suitable position. At the same time, the position of the stent needs to be adjusted when placed, which affects the efficiency of use. To this end, we propose an ophthalmic surgery auxiliary stent to solve the above problems. Utility Model Content
