Visual puncture needle system with protection function

Abstract

The invention relates to a visual puncture needle system with a protection function. The visual puncture needle system comprises a puncture needle tube and a tube body used for human body puncture. The needle tube connecting piece is connected to the rear end of the puncture needle tube and used for being held by an operator; the image acquisition mechanism is detachably connected with the needle tube connecting piece; and the bouncing core mechanism is detachably connected with the needle tube connecting piece. Compared with the prior art, the device has the beneficial effects that the image acquisition mechanism and the bouncing core mechanism are matched at the same time; the bouncing core mechanism can ensure that an operator can timely know the puncture condition in the puncture process, and the puncture action can be timely stopped after the puncture is completed, so that other tissues are prevented from being accidentally injured; and the image acquisition mechanism can know the condition in the body of the patient in real time, so that the safety of the operation is improved through double assurance.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a visible puncture needle system with protection function. Background technique [0002] In the third space of the human body, such as the thoracic cavity, joint cavity, etc., inflammation or certain diseases often cause fluid accumulation in the cavity. When the fluid accumulation is large, it may cause symptoms such as dyspnea, abdominal distension, and joint movement limitation. At this time, doctors often use it. The puncture needle penetrates the above-mentioned cavity and extracts the fluid to achieve the purpose of treatment. When the effusion is small but may be accompanied by infection, internal bleeding and other causes, doctors often need to puncture to extract part of the fluid for diagnosis. At present, doctors only rely on experience and hand feeling in the puncture process, and cannot completely avoid the tip of the puncture needle from piercing the intestine, lungs...

AI Technical Summary

Problems solved by technology

At present, doctors rely entirely on experience and hand feeling in the puncture process, and cannot completely avoid the tip of the puncture needle piercing the intestines, lungs, large blood vessels and other tissues, which may cause serious side injuries

At the same time, if the effusion is located in a deep gully, the doctor cannot accurately position the tip of the puncture needle at the effusion during blind puncture, and cannot extract the fluid, and thus cannot make a diagnosis based on the extracted fluid, resulting in a higher probability of false negatives. high
