Positioning apparatus for biomedical use
A medical positioning apparatus including a telescopic member extending between first and second ends and having an adjustable length; a support member for receiving an object; a base member securable to a base; a first joint mechanism movably securing the support member to the first end of the telescopic member; a second joint mechanism including a housing with a top portion directly rotationally connected to the second end of the telescopic member, and at least one side portion directly rotationally connected to the base member and movably securing the base member to the second end of the telescopic member, a locking device operatively connected to the first and second joint mechanisms and the telescopic member, the locking device operable between a locked position and a released position; and a lock activation device to unlock the locking device biased in the locked position.
1. A medical positioning apparatus for positioning and holding an object, comprising:
a telescopic member extending along a single axis extending between a first end and a second end and having an adjustable length along the single axis, wherein the telescopic member comprises a first hollow elongated member and a second hollow elongated member;
a third hollow elongated member connected to the second hollow elongated member, wherein the second and third hollow elongated members are connected by a connector;
a lock activation device connected to the telescopic member, wherein a fluid connection extends between the lock activation device and a T-shaped manifold within the connector;
an interface member for receiving the object;
a first joint mechanism movably and securing the interface member to the first end of the telescopic member;
a second joint mechanism connected to the second end of the telescopic member;
a base member movably connected to the second joint mechanism;
wherein the second joint mechanism is directly rotationally connected to the base member and movably secures the base member to the second end of the telescopic member; and
wherein the first and second joint mechanisms each having at least two rotational degrees of freedom.
2. The medical positioning apparatus of claim 1 , wherein the base member comprises an elongated arm.
3. The medical positioning apparatus of claim 2 , wherein the elongated arm has an end secured to the second joint mechanism and another end with an adjustable clamp.
4. The medical positioning apparatus of claim 1 , wherein the first and second joint mechanisms each comprise a ball and a socket operatively connected together.
5. The medical positioning apparatus of claim 4 , wherein the ball comprises a first and a second hemispherical portions moveably connected together, the first hemispherical portion being fixedly secured to the telescopic member.
6. The medical positioning apparatus of claim 1 , wherein the base member extends substantially parallel to the telescopic member.
7. The medical positioning apparatus of claim 1 , wherein the second hollow elongated member has a given end slidably engaged within the first hollow elongated.
8. The medical positioning apparatus of claim 1 , wherein the third hollow elongated member is connected to the second joint mechanism.
9. The medical positioning apparatus of claim 1 , wherein the lock activation device is a pump fluidly connected to the first and second joint mechanisms.
10. The medical positioning apparatus of claim 1 , wherein the lock activation device is directly connected to the connector.
11. The medical positioning apparatus of claim 1 , wherein the T-shaped manifold comprises a first outlet and second outlet.
12. The medical positioning apparatus of claim 11 , wherein the first outlet is fluidly connected to a locking unit of the second joint mechanism.
13. The medical positioning apparatus of claim 11 , wherein the second outlet is fluidly connected to a locking unit of the first joint mechanism.
14. The medical positioning apparatus of claim 11 , wherein the first outlet is fluidly connected to a first locking unit within the third hollow elongated member and the second outlet is fluidly connected to a second locking unit within the first hollow elongated member.
