Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and more specifically, to a multi-degree-of-freedom suspension bracket. Background Art

[0002] The optical positioning system is fixedly installed in the hospital treatment room. Before and during radiotherapy, it tracks the patient's body surface displacement in real time to ensure accurate positioning of the treatment. It is widely used in gamma knife and linear accelerator equipment. The optical positioning system is fixed in a suitable position in the treatment room through a hanging bracket, and the translation and angle adjustment are carried out within a certain range to ensure the accuracy and stability of positioning.

[0003] After searching, the patent document with the existing publication number CN213236653U provides a suspension bracket for production. The device can stretch or fold the length of the first connecting rod, the second connecting rod, and the third connecting rod through the adjustment locking button in the telescopic mechanism, thereby increasing the working range of the suspension bracket, and the gantry and the cross bar can hang objects, thereby meeting the use requirements.

[0004] The adjustment of the above-mentioned suspension bracket relies on multiple adjustment locking buttons to fix the positions of the first link, the second link, and the third link. Since the installation positions and heights of the adjustment locking buttons are different, the adjustment of the above-mentioned suspension bracket is relatively cumbersome. When the optical positioning system is in use, the adjustment frequency is high, but the adjustment range is small. The existing suspension bracket cannot meet the use requirements. In view of this, we propose a multi-degree-of-freedom suspension bracket. Utility Model Content

[0027] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings.

[0028] See also Figure 1 ,The present application provides a multi-degree-of-freedom suspension bracket, comprising a support base 1, a telescopic rod 2, a rotating arm 3, a U-shaped clamp 4, a turntable connector 5 and a host connector 6;

[0029] The telescopic rod 2 is installed on the supporting base 1, the rotating arm 3 is horizontally installed at the end of the telescopic rod 2, the U-shaped clamp 4 is horizontally installed at the end of the rotating arm 3, the turntable connector 5 is vertically installed at the end of the U-shaped clamp 4, and the mainframe connector 6 is connected and fixed to the turntable connector 5.

[0030] See also Figure 2 The support base 1 includes a first top plate 101, a second top plate 102, an X-direction positioning plate 103 and a Y-direction positioning plate 104. The first top plate 101 and the second top plate 102 are fixedly mounted, and a gap is left between the first top plate 101 and the second top plate 102;

[0031] The X-axis positioning plate 103 is slidably connected to the second top plate 102 and fixed by bolts; the Y-axis positioning plate 104 is slidably connected to the X-axis positioning plate 103 and fixed by bolts; the telescopic rod 2 is fixedly installed on the Y-axis positioning plate 104.

[0032] The first top plate 101 is fixed to the ceiling by using expansion bolts; the second top plate 102, the X-direction positioning plate 103 and the Y-direction positioning plate 104 are then installed in sequence by using bolts, and finally the telescopic rod 2 is installed at the bottom of the Y-direction positioning plate 104. During the installation process, the installation position of the X-direction positioning plate 103 and the Y-direction positioning plate 104 can be adjusted to change the installation position of the telescopic rod 2, thereby overcoming the installation error of the first top plate 101.

[0033] See also Figure 3 The telescopic rod 2 includes an outer tube 201, an inner tube 202 and a clamping sleeve 203; the inner tube 202 is slidably inserted in the outer tube 201, and the clamping sleeve 203 is sleeved outside the outer tube 201 and threadedly connected with the outer tube 201. When the device is in use, the clamping sleeve 203 can be rotated to reduce the clamping force of the outer tube 201 on the inner tube 202 to adjust the extension length of the inner tube 202, and then the position of the inner tube 202 can be fixed by rotating the clamping sleeve 203 in the opposite direction.

[0034] In addition, an anti-falling bolt 204 is fixedly connected to the outer tube 201 , and a limiting groove 205 is provided on the side wall of the inner tube 202 . The anti-falling bolt 204 is located in the limiting groove 205 to prevent the inner tube 202 from slipping.

[0035] In addition, a locking nut 206 is threadedly connected to the end of the inner tube 202, and the locking nut 206 is in frictional contact with the rotating arm 3. By rotating the locking nut 206, the friction force between the rotating arm 3 and the turntable connecting member 5 is changed, and the rotation damping of the rotating arm 3 is adjusted.

[0036] See also Figure 4 The U-shaped clip 4 is threadedly connected with a connection adjustment nut 301, and the adjustment nut 301 abuts against the turntable connecting member 5. The U-shaped clip 4 is connected to the turntable connecting member 5 by a friction gasket to damp the rotation.

[0037] Working principle: When the device is in use, the optical positioning system is connected and fixed to the host connector 6, and then the turntable connector 5 is limited by rotating the adjustment nut 301 to complete the installation of the optical positioning system.

[0038] Since the swivel arm 3 is horizontally rotatably installed at the bottom of the telescopic rod 2 and the U-shaped clamp 4 is horizontally rotatably installed at the bottom of the swivel arm 3, no additional fixing measures are required. The position of the optical positioning system can be fixed by utilizing the rotational friction between the swivel arm 3 and the telescopic rod 2 and the rotational friction between the U-shaped clamp 4 and the swivel arm 3. When the user adjusts the optical positioning system, he only needs to push the optical positioning system.
