Abstract: The present invention relates to a medical pendant lifting system, comprising a main frame, a driving device, a transmission device, a main body component, a first connecting rod, a second connecting rod, a third connecting rod and a connecting head, wherein the driving device drives the main body component and the third connecting rod via the transmission device; the driving device is connected to the main frame by a first rotating shaft; the main body component is connected to the main frame by a third rotating shaft, connected to the output component of the transmission device by a second rotating shaft, connected to the connecting head by a fifth rotating shaft, and connected to the second connecting rod by a sixth rotating shaft; the third connecting rod is connected to the main frame by a fourth rotating shaft, and connected to the second connecting rod by a seventh rotating shaft; the first connecting rod is connected to the second connecting rod by a ninth rotating shaft, and connected to the connecti

Abstract: The invention relates to a head support (10, 100) for operating tables, comprising a rotatably mounted first holding element (12) for surrounding a first side of a patient's head receivable in a receiving area (32) and an also rotatably mounted second holding element (14) for surrounding a second side of the head. The two holding elements (12, 14) are coupled to each other in a coupling area by means of a coupling element (16) such that when one of the holding elements (12, 14) is rotated, the coupling element (16) also rotates the other holding element (12, 14). Between the coupling area and the receiving area (32) a stationarily arranged supporting element (33) for supporting the head receivable in the receiving area (32) is provided.

Abstract: The invention provides an intelligent close loop recognition restoring feedback device including a back plate, a casing is disposed at a side of the back plate, and a covering plate is disposed on the casing. A rotating pivot is protruded from the middle of the covering plate and the middle of the casing. Two transverse rotating handles are disposed at an end of the rotating pivot, and the rotating handles are fixed by a plug cover. Two moving-sliding blocks are disposed in the casing, and the two moving-sliding blocks are connected to each other via tensile elastic elements. A cam is disposed between the two moving-sliding blocks, and each moving-sliding block is provided with a cylindrical pin. The two cylindrical pins are located at the same position on the moving-sliding blocks and abut against the edge of the cam.
