A surgical stapler and a control method therefor. A control part of the surgical stapler is used to acquire a real-time drive current value and a jump current average value of a drive part; then, determine the difference value between the drive current value at a current moment and the drive current value at a previous moment; compare the difference value to the jump current average value, if the difference value is greater than the jump current average value, control the drive part to stop working. Thus, an operator does not have to determine by his or herself whether anastomosis action is completed before operating the surgical stapler, thereby increasing surgical efficiency.

Data sources provide access to data. The data stored by the data source may be transformed before use by an application. Different data sources support different transformations. A data agent sidecar for the application accepts work orders from the application and submits work orders to data sources. A work order identifies a data source from which data is requested. The work order optionally includes one or more transformations to be applied to the data from the data source. The data agent sidecar determines, for the data source from which data is requested, which transformations can be performed by the data source and which transformations are not supported by the data source.
