This utility model provides a corneal foreign body removal device, relating to the field of ophthalmic medical devices. It includes a handle, a working part, a connecting part, and a neck. The working part is fitted onto the middle of the outer wall of the handle, and the connecting part is located at one end of the handle. The neck is detachably connected to the handle via the connecting part. The device also includes a head, the tip of which is tilted at a certain angle to one side, forming a crescent-shaped curved surface. This crescent-shaped curved surface extends laterally along the inclined side to form a single-sided cutting edge. Through the cooperation of these structures, compared with existing technologies, it has the following advantages: First, the bidirectional inclined cutting edge structure significantly reduces the risk of corneal stroma tearing. The blunted rounded corners increase the contact area during device retraction, effectively avoiding secondary trauma caused by micro-movements of the eyeball and reducing the risk of corneal perforation. Second, different sizes of cutting edges can be replaced through the connecting part to adapt to differences in foreign body size, reducing the probability of misoperation due to repeated device adjustments.

The utility model discloses a medical dressing with medicine loading groove, medical dressing includes polyurethane film and antiseized layer, be equipped with a plurality of medicine loading groove on the polyurethane film, be equipped with hydrogel layer in the medicine loading groove, fill in the medicine of hydrogel layer, one side of the antiseized layer with polyurethane film is equipped with medicine loading groove and is close -fitted. The utility model discloses medical dressing is equipped with medicine loading groove on polyurethane film, fills hydrogel layer in medicine loading groove inner chamber, and the medicine is loaded in hydrogel, can promote the slow -release capacity of medical dressing. The medicine is distributed on the slow -release skeleton, and the slow -release skeleton is prepared through three -dimensional micro -nanometer printing, and the inner chamber is hollow, and the shape of slow -release skeleton is customized according to the shape of medicine loading groove, makes the quantity of slow -release skeleton in medicine loading groove maximization, forms medicine -skeleton load structure, can accommodate more medicine in medicine loading groove to good slow -release effect.

The utility model discloses an auxiliary device for spinal surgery patient rehabilitation, which comprises a stool, a backrest plate is arranged on the back of the stool, a positioning column is fixed in the middle of the lower side of the backrest plate, a positioning cylinder for positioning and supporting the positioning column is fixed on the side surface of the stool, and a guide frame is fixed on the side surface of the stool. A positioning rack is arranged in the guide frame in a sliding mode, a gear is fixed to the positioning column, and the gear is meshed with the positioning rack. According to the auxiliary device for rehabilitation of the spine surgery patient, the back of the patient can be effectively supported in the training process, so that a certain protection effect is achieved, secondary trauma on the spine under the condition that the spine is not completely rehabilitated is avoided, meanwhile, when the auxiliary device is used for assisting the spine patient in waist twisting training, certain resistance can be applied to the spine patient, and the spine is more comfortable. The spine rehabilitation training device is used for mobilizing muscle groups around the spine to move, stimulating muscle strength bursting and assisting a patient in spine rehabilitation training, and has a high training effect.
