Abstract

The invention discloses a minimally invasive customized puncture guiding device and a puncture positioning optimization method. The device comprises a fixed base, a double-row longitudinal sliding block guide rail structure, a lifting platform, a transverse sliding seat, a double-row transverse sliding block guide rail structure and a template reversing mechanism. The double-row longitudinal sliding block guide rail structure is installed on the fixed base; the lifting platform is mounted on the double-row longitudinal sliding block guide rail structure; the transverse sliding seat is installed on the lifting platform; the double-row transverse sliding block guide rail structure is installed on the transverse sliding seat; the template reversing mechanism is installed on the double-row transverse sliding block guide rail structure; a puncture template fixing piece is installed and connected to the tail end of the template reversing mechanism through a tail end steering structure; and apuncture template is installed and fixed on the puncture template fixing piece. Therefore, the positioning precision of the puncture template is improved, so that the precision of a puncture operation is improved and the operation efficiency is improved; and the change of the vertical distance between the highest position and an operation bed when different patients adopt customized puncture positions can be met.

Description

technical field [0001] The invention relates to a movable device for medical objects in the field of medical instruments, and relates to a minimally invasive custom-made puncture guide device and a puncture positioning optimization method. Background technique [0002] Puncture is a widely used technology in modern medical surgery, especially in minimally invasive surgery. It is an important means of many medical diagnosis, treatment and scientific research, including biopsy sampling inspection and percutaneous puncture Radiofrequency ablation, implantation of radioactive particles, drainage of body fluids, etc., are used in the biopsy and treatment of liver, kidney, lung and other organs. [0003] Needle biopsy is an important means of disease diagnosis and differential diagnosis because it has the advantages of simple operation, small trauma and low cost to obtain tissue samples directly from the lesion. Manual puncture biopsy guided solely by CT images requires multiple ...
