Problems solved by technology

[0004] The tracking tools of the existing optical navigation systems are all rigid, and the tip of the tool and the tracking structure must remain relatively stationary, and it is impossible to locate flexible tools, such as laser optical fibers, etc.
The magnetic navigation system can attach a magnetic coil to the front end of the flexible tool to locate the apex of the flexible tool. However, this technology can only be applied to tools with larger diameters such as laryngoscopes and fiberoptic bronchoscopes, and the accuracy of magnetic navigation cannot be achieved. Satisfy Orbital Surgery Requirements

Embodiment Construction

[0021] Such as figure 1 As shown, the flexible tool positioning device for orbital surgery of the present invention consists of three parts, a guide part, a temporary storage part, and a tracer part, wherein the guide part is a hard stainless steel needle tube 1 with an internal thread mechanism at one end, and the inner part of the needle The diameter is 0.8 ~ 1.2mm, for flexible tools to pass through, such as medical laser optical fiber. The temporary storage part is composed of a cover plate 5 and a temporary storage tank 2. One end of the temporary storage tank 2 has an external thread mechanism matching the internal thread of the hard needle tube 1. The hard needle tube 1 and the temporary storage tank 2 are connected by an internal and external thread mechanism. The cover plate 5 and the temporary storage slot 2 are connected by a card slot. Blood, body fluid or purulent fluid returned during puncture can be stored in the temporary storage tank 2 . The tracer part is c...

Abstract

The invention belongs to the field of medical instruments and discloses an orbital surgical flexible tool tip positioning device for an optical navigation system. The orbital surgical flexible tool tip positioning device comprises a guide portion, a temporary storage portion and a tracing portion. The guide portion is provided with a hard needle tubing (1), and an internal thread mechanism is arranged at one end of the hard needle tubing (1); the temporary storage portion consists of a cover plate (5) and a temporary storage groove (2), an external thread mechanism matched with the internal thread mechanism of the hard needle tubing (1) is arranged at one end of the temporary storage groove (2), the hard needle tubing (1) and the temporary storage groove (2) are connected through the internal and external thread mechanisms, and the cover plate (5) and the temporary storage groove (2) are connected through a clamping groove. The tracing portion consists of reflection balls (3) and a reflection ball support (4), the reflection balls (3) and the reflection ball support (4) are in threaded connection, and the reflection ball support (4) and the temporary storage groove (2) are in threaded connection.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an orbital surgery and a computer-aided navigation system, and is a positioning device for the tip of an orbital surgery flexible tool used in an optical navigation system. Background technique [0002] The computer-aided navigation system is a surgical assistance system that organically integrates medical imaging, computer image processing, and spatial positioning technologies. It can provide the precise spatial location of the tracking device in real time and inform the surgeon of the spatial location relationship with the surrounding tissues. [0003] At present, the navigation system mostly adopts infrared optical positioning technology. By identifying the positioning reference frame with infrared reflection source or emission source fixed on the skull, the virtual coordinate system of the patient's imaging data is registered with the patient's actual world coordinate system...
