Probe for metal object positioning system in human body

Abstract

The invention discloses a probe for a metal object positioning system in a human body. The probe comprises a housing (2), a plug (1), a coil (3), a sterile sheath (4) and a magnetic core (6), wherein an inner cavity is arranged in the housing (2); the coil (3) is wound on the magnetic core (6); the coil (3) and the magnetic core (6) are installed in the inner cavity of the housing (2); and the coil (3) is configured to be connected with the plug (1) through a plugging port, so that the probe is smaller in size and is more suitable for being used in operation.

Description

1. Technical field [0001] The invention relates to a probe for a metal object positioning system in a human body, in particular to a probe for a metal object positioning system in a human body adapted to detect shrapnel and screws. 2. Background technology [0002] Metal objects such as shrapnel and screws exist in the human body due to various reasons. If these metal objects cannot be taken out in time, they will cause harm to people's physical conditions. Bullets and shrapnel can cause many harms to the human body, so in most cases it is Metals such as screws in the body need to be removed sometimes. The primary problem of removal is positioning. During surgery, these metal objects need to be positioned in the human body. Therefore, the metal object positioning system in the human body is an important medical diagnosis. equipment, and the probe is an important part of the metal object positioning system in the human body; the commonly used positioning methods are X-ray flu...

[0002] Metal objects such as shrapnel and screws exist in the human body due to various reasons. If these metal objects cannot be taken out in time, they will cause harm to people's physical conditions. Bullets and shrapnel can cause many harms to the human body, so in most cases it is Metals such as screws in the body need to be removed sometimes. The primary problem of removal is positioning. During surgery, these metal objects need to be positioned in the human body. Therefore, the metal object positioning system in the human body is an important medical diagnosis. equipment, and the probe is an important part of the metal object positioning system in the human body; the commonly used positioning methods are X-ray fluoroscopy (or spot film) and CT, but they are inconvenient to carry, unintuitive, inaccurate and harmful to health. and other shortcomings, and ultrasound is similar to bone ultrasound in detecting metal foreign bodies, so it is difficult to identify metal foreign bodies around bones; hand-held detectors (commonly used in airport security checks) are easy to carry and easy to operate

Since the detector is built with an analog circuit, the detection distance and accuracy cannot be adjusted, so the anti-interference performance is poor, and it is easy to cause de-judgment and missed judgment; not only that, the detector probe on the market is too large, the signal generated is not good, and it can only be determined With or without, the detection target cannot be located
