Abstract

The invention discloses a precision medical instrument which comprises an operation end, a cable tube and an execution end. The operation end, the cable tube and the execution end are sequentially connected with one another; the precision medical instrument can be controlled by doctors or assistants from the operation end in an in-vitro manner, at least one hole is formed in a side wall of the execution end, the ends of a plurality of shaft levers are close to the holes, a balloon, a needle-shaped component, an imaging lens and an auxiliary airbag are fixed to the top of at least one shaft lever, and a partition plate is arranged between each balloon and the corresponding needle-shaped component, is welded inside the execution end and has deflection. The precision medical instrument has the advantages that the execution end can be positioned at distal ends by the aid of positioning technologies, accordingly, rotation can be prevented, and the puncture and sampling precision can be improved.

Description

technical field [0001] The present invention relates to methods and systems for delivering medical devices or instruments to specific cellular locations within and adjacent to body cavities and tissues. Background technique [0002] When diagnosing and treating diseases of various body cavities and organs, various medical devices need to be delivered to specific positions in organs and tissue parts. [0003] Often, there is also a need to deliver medicinal or therapeutic substances to remote and less accessible blood vessels and lumens of other body organs such as the lungs. It is also important to be able to deliver defined doses of cytotoxic therapeutic and diagnostic substances directly into target tissues, as such substances are often expensive or can cause serious harm if delivered in excess. Therefore, there is a need for a device capable of delivering therapeutic and diagnostic agents directly to target tissues in the human body. [0004] And it is expected that var...
