Guide instrument box and puncture guide and release mechanism

Abstract

The invention relates to a guide instrument box and a puncture guide and release mechanism. The guide instrument box comprises a main body and a guide opening and closing flap extending out of the side part of the main body, wherein the guide opening and closing flap comprises a first guide opening and closing flap and a second guide opening and closing flap which are connected through a guide flap rotating shaft; the guide opening and closing flap maintains the closed state through an elastic element so as to form a through hole through which a puncture needle passes; an inclined surface is formed on the surface of one side of the second guide opening and closing flap; and the inclined surface is configured to be abutted against a release push rod inserted into a first depth range from the back part of the main body, so that the opening degree of the guide opening and closing flap is controlled on the basis of the insertion depth of the release push rod. In the scheme provided by theembodiment of the invention, the guide instrument box has the opening and closing function; the guide instrument box and a control arm can share a driving device; the invasion and occupation on the operation space are smaller; the structure is simple; the operation is convenient and fast; and the cost is low.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a guiding instrument box and a puncture guiding and releasing mechanism. Background technique [0002] Cancer is a major disease that endangers human health. In recent years, with the continuous development of pulsed bioelectricity, electric field pulses have received extensive attention for their non-thermal, minimally invasive biomedical utility, and have been gradually applied to the clinical treatment of tumors. Minimally invasive therapy often needs to reach the lesion area in the human body through a puncture needle for treatment, and the puncture needle usually needs to be positioned with a puncture template under the guidance of ultrasound or other medical imaging equipment, so as to reach the expected target position. [0003] The existing multi-needle puncture guidance system has an opening and closing mechanism for positioning the puncture needle, but sinc...
