Abstract
Abstract A positioning device for positioning an instrument in three dimensions, the device comprising at least one arm which is essentially rigid having a first end and a second end, the second end being hinged relative to a support stand via at least one hinge axis, and said instrument being mounted on a support which is connected to the second end of the arm via at least one hinge axis, wherein said instrument comprises an exploration probe and said support for the instrument comprises a device for motion in translation enabling the instrument comprising the exploration probe to be moved in translation relative to the second end of the arm, making it possible to perform exploration for each of the translation positions. The invention enables the instrument at the end of the positioning device to be moved in translation, thereby providing a maximum amount of freedom for positioning the instrument in three dimensions and facilitating locating operations, particularly in the context of transrectal echographic location, this being particularly useful for therapeutic treatment of the prostate.

Claim 2
Dependent Claim
126 words
A positioning device for use in three dimensional positioning of a support having an instrument for use with a therapeutic treatment apparatus, the device comprising a stand, at least one substantially rigid arm having a first end and a second end, a first hinge means for securing the first end to said stand for movement about at least one hinge axis, a second hinge means for securing said support to the second end of said at least one arm for movement about at least one hinge axis, and means for moving said support in translation relative to the second end of said at least one arm for enabling said instrument to be moved in translation relative to said second end of said at least one arm.
Claim 3
Dependent Claim
53 words
A device according to claim 1, wherein said at least one arm comprises first and second arms and further comprising a third hinge means moveable about at least one hinge axis for securing said first and second arms to each other, said support being secured to the free end of said first arm.
Claim 4
Dependent Claim
29 words
A device according to claim 2, further comprising locking means for simultaneously locking said first, second and third hinges thereby restricting movement of said hinges about their respective axes.
Claim 5
Dependent Claim
52 words
A device according to claim 3, wherein each hinge means includes a moving part and a stationary part, and wherein the locking means comprises means for effecting relative movement between the moving parts and the stationary parts and wherein said means for effecting movement are of the pneumatic or the hydraulic type.
Claim 6
Dependent Claim
39 words
A device according to claim 4, wherein said first and second arms comprise tubes having internal passages which accommodate a pneumatic or hydraulic fluid under pressure for effecting said relative movement between said stationary parts and said moving parts.
Claim 7
Dependent Claim
61 words
A device according to claim 2, wherein said first, second and third hinges each comprises a ball-and-socket type joint and wherein at least some of the sockets of said ball-and-socket joints have their axes of symmetry at acute angles of inclination relative to the axis of their attached arms, said angle of inclination lying in the range of 20° to 65°.
Claim 8
Dependent Claim
76 words
A device according to claim 6, wherein the means for moving the support in translation comprises a link member secured at one end to said support and at the other end to the socket at the free end of one of said first arm, and wherein the angle of inclination between said socket and said link member is different from the angle of inclination between the sockets of the other ball-and-socket joints and their attached arms.
Claim 9
Dependent Claim
