Abstract
An elastic element (1, 11, 21) having high flexural strength at short overall length for the use in a stabilization device (100) for bones or vertebrae is provided. The elastic element (1, 11, 21) is provided in the form of an essentially cylindrical body, wherein an elastic portion comprising at least two coaxial helical springs is provided. All coils of the helical springs have the same lead (α) and are arranged so that the coils (3) of one helical spring extend between the coils (4) of the other helical spring at least in a portion. The elastic element (1, 11, 21) thus formed can be part of a bone screw (60, 80, 101, 101′), of a rod-shaped element (50) or of other elements used in a stabilization device (100).
Claims8
A pressure-pulse-wave detecting probe for detecting a pressure pulse wave generated by an artery of a living subject, comprising:
- a sensor portion which has at least one pressure detecting element and a press spice that is to be positioned manually by an operator, relative to the artery of the subject, and is to be pressed manually by the operator, against the artery of the subject via a body surface of the subject, such that the pressure pulse wave is detected by said at least one pressure detecting element which is arranged on said press surface;
- and
- an indicator which is provided to be integral with said sensor portion, and provides an indication as to whether a value of pressure detected by each of said at least one pressure detecting element is suitable for detection of the pressure pulse wave or not
