Positioning apparatus for medical device

Abstract

This disclosure provides a positioning device comprising: a clamping assembly for securing a target object; a fixing assembly for pivoting onto a reference object and configured to rotate relative to the reference object along a first rotational direction; a first adjusting assembly connected to the fixing assembly and configured to linearly displace the clamping assembly in a horizontal direction; a second adjusting assembly connected to the first adjusting assembly and configured to angularly adjust the clamping assembly along a second rotational direction; and a third adjusting assembly connected to the second adjusting assembly and linked to the clamping assembly, configured to angularly adjust the clamping assembly along the first rotational direction. The positioning device disclosed herein can linearly and rotationally displace the clamping assembly of a medical device to secure it, allowing a physician to adjust the position of the medical device, facilitating precise insertion of the medical device into the human body.

Claims

1. A positioning device, comprising: A clamping assembly for clamping a target object; a fixing assembly for pivoting a reference object and configured to rotate relative to the reference object along a first rotational direction; A first adjustment component is connected to the fixed component and is configured to allow the clamping component to perform linear displacement in the horizontal direction; a second adjustment component is connected to the first adjustment component and is configured to allow the clamping component to perform angular adjustment in the second rotation direction. And a third adjustment component, which is connected to the second adjustment component and linked to the clamping component, and is configured to adjust the angle of the clamping component along the first rotation direction.

2. The positioning device as claimed in claim 1, wherein, The clamping assembly includes: a support base fixed to the third adjustment assembly; a plurality of clamping members disposed on the support base; and an adjustment member that is linked to the plurality of clamping members and is used to adjust the distance between the plurality of clamping members to selectively clamp or release the target object.

3. The positioning device as claimed in claim 1, wherein, The fixing component has a disc portion and a tip portion connected to the disc portion, wherein the disc portion is used to pivotally connect to the reference object, so that the tip portion swings relative to the reference object with the disc portion as the axis to adjust at least one of the height position and angle of the clamping component, and wherein the end of the tip portion extends to form a connecting portion for connecting to the first adjusting component.

4. The positioning device as claimed in claim 1, wherein, The first adjustment assembly includes: a driving member having a linear limiting hole; a first knob rod screwed to the fixing assembly; a base fixed to the end of the first knob rod and connected to the driving member; and a first rotating shaft disposed on the fixing assembly to pivotally connect the driving member, wherein the driving member is connected to the second adjustment assembly.

5. The positioning device as claimed in claim 4, wherein, The first knob is rotatable to drive the base to make linear displacement along the horizontal direction and to make the driving member rotate about the first pivot. The rotation of the driving member is restricted by the second adjustment component and converted into linear displacement to drive the second adjustment component to move.

6. The positioning device as claimed in claim 1, wherein, The second adjustment assembly includes: a bracket connected to the third adjustment assembly; a second knob rod screwed to the first adjustment assembly; a first adapter connected to the bracket and linked to the second knob rod; and a second pivot fixed to the first adjustment assembly to pivotally connect to the bracket.

7. The positioning device as claimed in claim 6, wherein, The second knob is rotatable to apply force to the first adapter, causing the bracket to rotate about the second pivot axis and drive the third adjustment component to swing, thereby adjusting the angle of the clamping component.

8. The positioning device as claimed in claim 1, wherein, The third adjustment assembly includes: a carrier member connected to the clamping assembly; a third knob rod screwed to the second adjustment assembly; a second adapter member connected to the carrier member and linked to the third knob rod; and a third pivot fixed to the second adjustment assembly to pivotally connect to the carrier member.

9. The positioning device as claimed in claim 8, wherein, The third knob is rotatable to apply force to the second adapter, causing the carrier to rotate around the third pivot and drive the clamping assembly to adjust the angle along the first rotation direction, thereby adjusting the angle of the target object relative to the target surface.

10. The positioning device as claimed in claim 1, wherein, At least one of the first adjustment component, the second adjustment component, and the third adjustment component includes a knob linkage structure.
