Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a prone device after ophthalmic surgery. Background Technique

[0002] At present, many ophthalmic surgeries require a prone position for a period of time after the operation. For example, vitrectomy in ophthalmic surgery is an important treatment method for retinal detachment. During the operation, silicone oil or inert gas will be filled. However, the density of silicone oil and gas is lighter than that of water and will float on the top. Taking a face-down position can make the silicone oil or gas float upward to effectively press against the retina and the hole, which is also beneficial to the absorption of subretinal fluid, promotes retinal repositioning, and at the same time can prevent silicone oil or gas from entering the anterior chamber, thereby causing postoperative complications such as corneal endothelial damage, corneal edema, pupillary block, glaucoma or lens opacity. According to the specific positions of retinal detachment and holes, the postoperative lying position will also be different. For example, patients with posterior pole holes (such as macular holes) should be in the prone position after the operation, and patients with temporal or nasal retinal holes should be in the lateral lying position after the operation. Clinically, the prone position is the most commonly used position for patients after silicone oil filling.

[0003] Most of the existing prone devices after ophthalmic surgery have the following problems:

[0004] First, most of the existing prone devices have fixed height and fixed angle, and cannot be adjusted in height, so they cannot adapt to patients of different heights, and cannot be adjusted in prone angle, so they cannot meet the prone angle requirements of patients with different postoperative conditions.

[0005] Second, when the patient lies prone, the chest will be against the front end of the prone device, and the distance between the front end of the prone device and the facial prone area is fixed. Due to the differences in the upper body shapes of patients, some patients cannot reach the facial prone area with their faces or their faces exceed the facial prone area, and it is impossible to align the face with the facial prone area well.

[0006] Third, when the patient assumes a face-down prone posture, for the need of postoperative recovery, some patients also need to perform oxygen inhalation operations. However, since the patient's face is buried in the facial prone area, it is very difficult to perform oxygen inhalation operations. Content of the Utility Model
