Embodiment Construction

[0017] see figure 1 , a percutaneous lung puncture three-dimensional laser guidance device is provided with a mount 1 , a slider 3 , a guide bracket 7 and a laser angle meter 6 .

[0018] The seat frame 1 is provided with an arcuate slideway, and the slider 3 is movably matched with the arcuate slideway. The slider 3 and the arcuate slideway are locked by fasteners 2 (several pieces are provided), and the guide bracket 7 is fixedly connected to the slider 3 by fasteners 4 . The laser goniometer 6 is fixed on the upper part of the guide bracket 7 through the connecting piece 5 and fastened screws. The direction of the laser beam 8 emitted by the laser goniometer 6 is facing the direction of the guide hole of the laser beam 8 set at the bottom of the guide bracket 7. The goniometer 6 is provided with a display screen.

[0019] The seat frame 1 is an arcuate seat frame, and the arcuate slideway is an arcuate hole along the center line of the arcuate seat frame 1 . The guide br...

Abstract

The invention discloses a percutaneous lung puncture three-dimensional laser guiding device, and relates to medical apparatuses for puncture operations. The percutaneous lung puncture three-dimensional laser guiding device is provided with a base frame, a slide block, a guiding support and a laser angle instrument; the base frame is provided with arc slide way, the slide block is movably matched with the arc slide way, the slide block and the arc slide way are locked through fastening parts, the guiding support is fixedly connected with the slide block through the fastening parts, the laser angle instrument is fixed to the upper portion of the guiding support, and the direction of laser beams emitted by the laser angle instrument right faces the direction of a laser beam guiding hole formed in the lower portion of the guiding support. The percutaneous lung puncture three-dimensional laser guiding device can conduct precise location, and achieve precise puncturing. Meanwhile, the percutaneous lung puncture three-dimensional laser guiding device is very simple in structure and convenient to operate, and as is tested by practical inspection, the effect is excellent.

Description

technical field [0001] The invention relates to a medical instrument for puncture operation, in particular to a three-dimensional laser guiding device for percutaneous lung puncture. Background technique [0002] Percutaneous lung puncture under CT positioning (hereinafter referred to as lung puncture) is widely used in many clinical disciplines. Including percutaneous lung biopsy, preoperative puncture positioning of pulmonary nodules, interventional therapy for lung tumors (ablation, particle implantation), etc. It is one of the most frequent operations in thoracic surgery, respiratory medicine, and medical oncology. It is an important method to obtain pathological specimens of pulmonary nodules for definite diagnosis, especially for cases that cannot pass bronchoscopic biopsy, and it is also a prerequisite for interventional treatment of lung tumors. In recent years, with the popularization of high-resolution spiral CT, the detection rate of small pulmonary nodules is ge...
