Multi-angle visual high-strength and high-tenacity self-sensing ceramic needle knife

Abstract

The invention discloses a multi-angle visual high-strength and high-tenacity self-sensing ceramic needle knife. The multi-angle visual high-strength and high-tenacity self-sensing ceramic needle knife comprises an image processing and displaying module, a minitype projector, a power source, a signal amplifier, an illumination mechanism regulator, signal lamps, a data processing module, a handle, a straight knife bar, a signal transmission line, a resistance detecting module, a knife rod and a curtain. The resistance detecting module is internally provided with a force sensor and is used for measuring resistance subjected by a knife edge at the end portion of the knife head rod in the advancing process in the tissue of the human body. The signal lamps represent different tissue layers where the knife edge at the end portion of the knife head rod enters of the human body. The data processing module processes data and controls the corresponding signal lamps to be turned on, and self sensing of the needle knife is achieved. The waterproof microscope lens can image a portion where the knife head rod arrives, and then the image is displayed on the image processing and displaying module. A doctor controls the position of the knife head rod in real time according to the image by observing the image on the image processing and displaying module, and the multi-angle visual high-strength and high-tenacity self-sensing ceramic needle knife can be used for multi-person and multi-angle consultation and used for occasions of teaching and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a multi-angle visualized high-strength and high-toughness self-sensing ceramic needle knife. Background technique [0002] The used needle knife in the hospital is a small needle knife at present, and it is made up of three parts, is respectively handle, straight knife bar and knife head bar. The material used for the straight knife bar and the knife head bar is steel. However, needle knives are often in contact with body fluids and are easily corroded. The straight knife rod is relatively thin, and its diameter is generally less than 4mm, which is easy to be brittle. [0003] Now there is another needle knife, which has an endoscope at the end, and a huge visualization device and analysis software outside. On the one hand, because this needle knife is too bulky, the flexibility of the needle knife cannot be maintained. On the other hand, the visualization...

Problems solved by technology

On the one hand, because this kind of needle knife is too bulky, the flexibility of the needle knife cannot be maintained

On the other hand, the visualization equipment and analysis software obviously lag behind the progress of the acupotomy incision during the operation, which is unfavorable to the time requirement of the operation, brings pain to the patient, and affects the treatment. Acupuncture doctors do not accept this technology.
