A puncture positioning tool for three-dimensional measurement angle

Abstract

The invention discloses a puncture positioning tool for three-dimensional angle measurement, and relates to the field of medical apparatuses and instruments. The puncture positioning tool structurally comprises a positioning support and an angle ruler combination device; the positioning support is formed by a plurality of transverse positioning strips, vertical positioning strips and annular clamping grooves, and the angle ruler combination device is formed by an I type angle ruler, an II type angle ruler, a rotating shaft and a fixing shaft; the rotating shaft is connected with the I type angle ruler and the II type angle ruler, and the II type angle ruler is formed by an angle ruler, a rotating ring and a pointer, wherein the rotating ring is connected with the II type angle ruler and the pointer, the fixing shaft is connected with the I type angle ruler and the structure of the annular clamping groove of the positioning support, the angle ruler combination device is of an integrated structure, and the positioning support and the angle ruler combination device are of split structures. The puncture positioning tool is simple in structure, convenience is provided for puncture angle measurement at the sagittal view and the horizontal position at the same time in a minimally-invasive surgery, the puncture accuracy is improved, and deviations between an actual puncture angle and a puncture angle provided by imaging information are avoided.

Description

Technical field [0001] The invention relates to the field of medical devices, in particular to a puncture positioning tool used for three-dimensional angle measurement. Background technique [0002] With the development of medical technology, the technology of minimally invasive surgery is becoming more mature. Because minimally invasive surgery has the advantages of less damage, less cost, and faster recovery, more and more doctors and patients have accepted it. [0003] At present, minimally invasive surgery has been successfully applied in many fields of clinical medicine, but the minimally invasive surgery guided by imaging technology (C-arm X-ray machine or CT) still has technical defects. Although, the minimally invasive surgical process of imaging technology-guided puncture involves two key steps: one is to accurately locate the lesion through imaging technology, and the other is to accurately puncture to the lesion after positioning. Among them, imaging technology can ass...

Problems solved by technology

However, the evaluation of the puncture angle by clinicians based on their own clinical experience and subjective judgment is an important reason for surgical failure or serious complications

[0005] The current situation that clinicians seldom determine the puncture path by actually measuring the puncture angle is mainly due to the lack of convenient and simple measurement tools in clinical practice, which often leads to the difference between the actual puncture angle in clinical work and the puncture angle provided by imaging data. deviation
