Problems solved by technology

[0006] The purpose of the present invention is to provide a fixed traction and tracking device for fracture fragments used in the orbital surgery endoscopic navigation system, which can be used in the surgery to solve the problem that the existing navigation system cannot visually and real-time display the spatial position of the fracture fragments during the operation. Repeated disassembly and assembly without re-registration can still maintain the original navigation accuracy

Embodiment Construction

[0045] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] A fracture fragment fixation traction tracking device for orbital surgery endoscopic navigation system, please refer to figure 1 and figure 2 , including a base part 1, a holding part 2 and a tracer part 3, the base part 1 and the tracer part 3 are fixed on the holding part 2.

[0047] Please refer to image 3 and Figure 4 As shown in the structural diagram of the base part 1, the bottom of the base part 1 is provided with an annular tooth-shaped structure 11, forming an annular tooth-shaped surface, which contacts with the surface of the bone block to increase friction. The center of the base part 1 is provided with a counterbore 12 structure, and the bottom of the counterbore 12 is provided with an annular chamfer 13 which facilitates the embedding of the titanium nail head. A square groove 14 is defined on the side...

Abstract

The invention discloses a fracture block fixing traction tracking device for an orbit surgery department endoscope navigation system. The fracture block fixing traction tracking device comprises a base part, a holding part and a tracking part. The bottom of the base part is provided with an annular-tooth-shaped structure in contact with the surface of a bone block, a countersink structure is arranged at the center of the base part which is fixed on the holding part through a nut, the tracking part is fixed on the holding part though a wedge protrusion, and the tracking part is provided with a witch ball array used for reflecting infrared rays. The fracture block fixing traction tracking device can be used for repair and reconstruction of orbit marginal bones of the orbit surgery department, the small base part can reduce influence on surgical operation, when the fracture block needs to be pulled and displaced, the holding part can be installed, and when the spatial position of the fracture block needs to be observed visually, the tracking part can be reinstalled. The fracture block fixing traction tracking device can be repeatedly assembled and disassembled in the operating process, and the original navigation precision can be maintained without registration again.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular, it is a fracture fragment fixation and traction tracking device used in orbital surgery endoscopic navigation system. bones. Background technique [0002] Orbital surgery endoscopic navigation system is a surgical assistance system that organically integrates medical imaging, computer image processing, spatial positioning technology and endoscopic imaging, and is an innovation in orbital surgery. It extends the limited field of view of the surgeon, making it easier for the surgeon to observe the deep tissue structure, while monitoring and warning to avoid iatrogenic injury. Its appearance has broken through the boundaries of traditional orbital surgery, promoted the transformation of the concept of orbital surgery, and made a qualitative leap in the effect of orbital surgery. [0003] At present, the navigation system mostly adopts infrared optical positioning technology....
