Multi-purpose adjustable fixing guide plate for percutaneous puncture operation

Abstract

The invention discloses a multipurpose adjustable fixing guide plate for percutaneous puncture operation, and relates to medical instruments. A plurality of groups of angle-adjustable puncture needle guide units are arrayed, and the units can select different specifications of apertures from 12G to 21G, so that the requirements of puncture operations on different needle entry points, different angles and different specifications of puncture needles are met, and the puncture guide plate design has compatibility and universality; a doctor can finish an operation more accurately and quickly under the assistance of the system, and the operation risk is reduced; the adjustable flexible design is adopted, and universality is achieved for different conditions of different patients; the multi-unit design meets the selection requirements of different needle inserting points, the flexible connection design improves the fitting degree of the puncture template and the body of a patient, the adjustable angle design of each unit meets the requirements of different needle inserting angles, various puncture dangerous areas can be avoided, and the focus position can be reached; meanwhile, the equipment can be reused after being disinfected, so that the burden of a patient can be reduced while the operation cost is reduced.

Description

technical field [0001] The invention relates to medical equipment, in particular to a multi-purpose adjustable fixed guide plate for percutaneous puncture operation. Background technique [0002] Percutaneous puncture technology is mainly used for minimally invasive surgery that requires percutaneous catheter insertion. Common percutaneous puncture operations include percutaneous biopsy, percutaneous ablation, and percutaneous radioactive seed implantation. Acquire the lesion tissue with a needle for further diagnosis and treatment planning; percutaneous ablation uses interventional ablation to ablate and kill the lesion tumor tissue to complete the treatment requirements; Implant tumor lesion tissue, damage and destroy tumor tissue to the greatest extent, so as to achieve the purpose of tumor treatment. [0003] With the development of modern medicine, minimally invasive interventional surgery has gradually become the first choice for tumor treatment; compared with traditi...

Problems solved by technology

[0005] Most of the existing fixed guide plates for puncture surgery are individually designed 3D printing templates, which are reverse-modeled from the tomographic information of the patient, using computer-aided design to design the guiding path of the puncture needle, and then made by 3D printing; such 3D The printing template is a rigid structure, tailor-made for the patient, not universal and reapplicable, and time-consuming and labor-intensive, expensive
