Description

Technical Field

[0001] This utility model relates to the field of medical device calibration technology, specifically to an installation structure for a multi-angle adjustable optical positioning device. Background Technology

[0002] As modern surgical procedures demand increasingly more minimally invasive and precise techniques, surgical navigation systems are gaining popularity. Optical positioning devices, as the most critical component of these systems, are receiving significant attention for their data accuracy and ease of operation. Currently, most optical positioning devices are mounted on top of the navigation trolley, using traditional mounting brackets. This results in limitations in the surgical field of view and adjustment angles, and imposes a fixed position on the trolley relative to the operating table, making it difficult to meet the positioning and navigation needs in complex situations.

[0003] Therefore, the mounting structure of a multi-angle adjustable optical positioning device can achieve multi-angle rotation adjustment, which can minimize the problem of visual obstruction caused by too many and messy surgical instruments. Utility Model Content

[0004] The purpose of this invention is to provide an installation structure for an optical positioning device that can be adjusted at multiple angles, thereby minimizing the obstruction of the field of vision caused by an excessive number and clutter of surgical instruments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for a multi-angle adjustable optical positioning device, comprising a support arm, with a sleeve 1 and a sleeve 2 respectively provided at both ends of the support arm. Sleeve 1 is rotatably connected to the optical positioning device. Sleeve 2 is connected to a adapter 1, which is fixed relative to the support arm. A rotating component is provided inside the adapter 1. The end of the adapter 1 away from the support arm is rotatable. The end of the adapter 1 away from the support arm is connected to an adapter 2, which is rotatable relative to the adapter 1. A mounting plate is connected to the bottom of the adapter 2, which is rotatable relative to the adapter 2. The mounting plate is connected to the optical positioning device.

[0007] Preferably, a support arm rotating friction cylinder is fitted on the outer side of the sleeve, and the sleeve is rotatably connected to the optical positioning device through the support arm rotating friction cylinder, which is made of plastic material.

[0008] Preferably, both sleeve one and sleeve two are set at a certain angle to the support arm. The angle setting can change the rotation direction of the connecting parts on both sides of sleeve one and sleeve two.

[0009] Preferably, the support arm rotates around the first sleeve as an axis, the first adapter includes a fixed end and a rotating end, a limiting groove is provided between the fixed end and the rotating end, the rotating end can rotate relative to the fixed end, and the second adapter is connected to the rotating end.

[0010] Preferably, the rotating end includes a connecting end, which is perpendicular to the rotating end. The connecting end is connected to both ends of the adapter. The sleeve two has a limiting hole corresponding to the limiting groove. The limiting block is stuck in the limiting hole and the limiting groove. The limiting block clamping plate is threadedly connected to the sleeve two and the rotating end, thus limiting and fastening the adapter to the sleeve two.

[0011] Preferably, the mounting plate and the adapter are connected by screws, and the adapter is provided with a pull hook at one end of the mounting plate.

[0012] Preferably, the mounting plate has a circular groove, the clamping block is placed in the circular groove, and the clamping block is connected to the mounting plate with screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the mounting structure of this multi-angle adjustable optical positioning device can rotate at multiple angles, which facilitates the adjustment of the position of the optical positioning device, expands its surgical field of view, and greatly improves the tracking and navigation efficiency; it can adapt to surgical environments with many interfering objects, avoids the problem of field of view obstruction, reduces the requirements for the surgical environment, and achieves damping locking through the friction of the plastic cylinder, which can be adjusted at all angles, and has low subsequent maintenance and upkeep costs.
