Embodiment Construction

[0023] like figure 2 and image 3 As shown, the rear magnetic part 1 is fixed on the array 2 .

[0024] Figure 4 It is a schematic diagram of the structural composition of the passive marker component in the embodiment of the present invention.

[0025] like figure 1 and Figure 4 As shown, the magnetic member 7 is installed in the inner cavity of the bottom seal 6 .

[0026] Further, the inner seal 5 is installed in the inner cavity of the bottom seal 6 after the magnetic part 7, and is fixed with the bottom seal 6, so as to limit the position of the magnetic part 7 and prevent it from going out come out.

[0027] Further, the reflective sticker 4 is a characteristic surface identified by an optical positioning system, which is limited between the upper surface of the bottom seal 6 and the bottom surface of the inner cavity of the outer seal 3 .

[0028] Further, the outer seal 3 and the bottom seal 6 are fixed to each other.

[0029] Further, the outer seal 3 of th...

Abstract

The invention relates to the technical field of medical instruments, in particular to a passive identification point assembly for detecting and positioning an optical system of a surgical robot, and particularly relates to a quick-changing device for the passive identification point assembly. The device comprises a rear-end magnetic part, an array and a passive identification point assembly. The passive identification assembly comprises an outer seal, a reflective sticker, an inner seal, a bottom seal and a magnetic part. The rear-end magnetic part is fixed on the array, and the bottom seal of the passive identification point assembly and the opposite assembly surface of the array are provided with guide surfaces, so that the passive identification point assembly can be quickly and accurately positioned and assembled. In addition, the passive identification point assembly can be magnetically attracted and fixed to the rear-end magnetic piece fixed to the array through the magnetic piece, external force is applied to the passive identification point assembly, and the passive identification point assembly can be rapidly detached from the array mounting groove. The passive identification point assembly is simple in structure, and the passive identification point assembly can be rapidly installed, positioned and disassembled.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a passive marking point assembly for detection and positioning of an optical system of a surgical robot, in particular to a quick change device for a passive marking point assembly. Background technique [0002] As people pay more and more attention to their own health problems, the demand for using robotic technology to assist surgery in specific scenarios is increasing. Surgical robots usually position the end of the robotic arm carrying the array through an optical positioning system and an array with passive marker components. Therefore, how to quickly install and disassemble passive marker components is a very important part of robotic surgery. . [0003] The current quick connection and disassembly device has a complicated structure and cannot realize the installation and disassembly of multiple passive marker components. Therefore, a quick change device is urgentl...
