Problems solved by technology

[0004] However, the active infrared reflective ball in the above scheme not only needs electricity to provide infrared light and is easily limited by wires, but also generates infrared light source itself, which may interfere with other surgical instruments, and the overall accuracy is limited.
It needs to be equipped with wires, the overall structure is relatively large, the installation position is not flexible enough, and the production cost is high

Embodiment 1

[0031] like Figure 1 to Figure 3 As shown, a passive infrared reflective ball according to the present invention includes a sphere 1 , an antibacterial film 10 , a reflective coating 2 , a mounting base entrance 3 , a mounting base 4 and a mounting frame 5 .

[0032] Wherein the antibacterial film 10 adheres to the surface of the sphere, the reflective coating 2 is bonded to the periphery of the antibacterial film 10, the sphere 1 is provided with an installation base inlet 3, and the installation base 4 includes a base Seat top 41 and threaded portion 42, the base top 41 is fixed on the sphere 1 through the installation base inlet 3, the threaded portion 42 is screwed into the threaded hole 51 on the mounting bracket 5 The installation base 4 is fixed on the installation frame 5 . Described antibacterial film 10 can be conventional medical use antibacterial film, and antibacterial film 10 described in the present embodiment preferably uses the antibacterial film that MacDer...

Embodiment 2

[0040] like Figure 4 As shown, a method for using a passive infrared reflective ball includes the following steps:

[0041] S1: Fix multiple passive infrared reflective balls on the mounting frame through the mounting base;

[0042] S2: Install the mounting frame on the surgical instrument, and the specific position of the mounting frame on the surgical instrument can be set according to the actual use requirements. Those skilled in the art should know that this embodiment does not limit it.

[0043] S3: The navigator emits infrared light to a plurality of passive infrared reflective balls, each of the passive infrared reflective balls reflects the infrared light back to the navigator, and the navigator calculates the position of the surgical instrument .

[0044]The navigator preferably includes a positioning sensor, a laser emitter, a processor and a display. The laser transmitter is used to emit infrared rays to the passive infrared reflective ball, which is reflected b...

Abstract

The invention discloses a passive type infrared light reflection small ball. The passive type infrared light reflection small ball comprises a ball body, a light reflection coating, an installation base inlet, an installation base and an installation frame. The small ball is reasonable in structure and low in manufacturing cost. Compared with an active type infrared light reflection small ball, no infrared light needs to be provided for the small ball through electric power, an assembly composed of the passive type infrared light reflection small balls is small and is not limited by wires, and the passive type infrared light reflection small balls can be flexibly and freely arranged in all positions of surgical instruments. More importantly, the passive type infrared light reflection small ball can not produce infrared light sources to interfere with other surgical instruments. The shape and the position of the assembly composed of the passive type infrared light reflection small balls can be customized according to requirements of doctors, and therefore the visible range of surgical instruments is widened. The invention further provides a use method of the passive type infrared light reflection small ball. The ball body serves as a reference point on surgical instruments, infrared light are transmitted by a navigator and are reflected to the navigator through the ball body, the positions of surgical instruments can be calculated by means of the navigator through combination with the corresponding algorithm, and accuracy is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a passive infrared reflective ball and a method for using the same. Background technique [0002] Currently, in surgical navigation, it is necessary to track the position of surgical instruments. The existing navigator has complex structure and unsatisfactory working performance. [0003] The infrared optical positioning system (navigator) emits infrared light and is reflected by the active reflective balls. The navigator can accurately identify the ball set composed of multiple active reflective balls, and calculate the relative coordinate conversion algorithm. The coordinates of the tip of the surgical instrument are obtained to realize the positioning of the surgical instrument. [0004] However, the active infrared reflective ball in the above scheme not only needs electricity to provide infrared light and is easily limited by wires, but also generates infrared ligh...
