Examples of the disclosure relate to a method and apparatus for processing a document, a device, and a medium. The method includes: obtaining document parameter information of a document to be created in response to satisfying a preset online document creation condition; and generating a new target online document based on the document parameter information. The preset online document creation condition includes at least one of the following conditions: a preset document update period is reached, and a target data object is collected through the target online document in the update period; and a size of data in a first online document reaches a preset size of data, or a first online document is determined to fail to completely bear a size of data to be written in a next data collection period or a data collection task.

Method and apparatus for processing document, device and medium

A femoral head support device, in particular a mineralized collagen-based femoral head support device applicable to the treatment of early osteonecrosis of femoral head. The device is made from a dense, homogeneous organic/inorganic composite, wherein the organic phase includes collagen and inorganic phase includes nano calcium phosphate salt, and the device is of a cylinder having an upright through hole and also has a support strength of up to 4000-6000N. By implementing a method for manufacturing such mineralized collagen-based femoral head support device, the mineralized collagen-based femoral head support device with mechanical properties equivalent to human cortical bone can be manufactured; and the mineralized collagen-based femoral head support device can meet the demand for clinical treatment of early osteonecrosis of femoral head to avoid the continuous collapse of necrotic femoral head.
