Ultrasonic guided puncture device

The present invention relates to an ultrasonic device, and more particularly to an ultrasonic guided puncture device.

Vascular puncture is very common in general human body treatment, and medical personnel must undergo considerable specialized training and accumulation of experience to confirm the correctness of the vascular puncture position. However, it is difficult for medical personnel to perform vascular puncture when the patient's blood vessels are not quite obvious and easy to find, or when the patient is older and the blood vessel elasticity is insufficient.

In addition to vascular puncture on the outer surface of human skin, there is also a need for vascular puncture at specific locations during surgery. At this point, the surgeon is more difficult to palpate the position of the puncture, but only rely on the aid of the instrument. Among them, if the ultrasonic image assisting device is used, the image of the blood vessel position is obtained by the principle of ultrasonic wave, thereby guiding the position of the blood vessel puncture and improving the accuracy of the puncture position.

For example, the "Semi-compliant needle guide for use with ultrasound transducers" of the US Patent Publication No. 5,924,992 discloses a device for ultrasonic guided vascular puncture, in which a probe for generating and receiving ultrasonic waves is also disclosed. The probe is ultrasonically detected at a position where the vascular puncture is to be contacted, and an ultrasonic image can be seen on an external screen connected to the probe for vascular puncture. However, the operator must look at the external screen while operating the vascular puncture through the screen instead of directly looking at the position of the human body to be punctured. The operation is not only inconsistent with human intuition and ergonomics, but also greatly increases the difficulty of operation. . In addition, the operator must control the needle guide in one hand, the other hand must control the needle tube for vascular puncture, and the eye must also stare at the external screen, which is quite inconvenient in operation, and is likely to cause insufficient puncture accuracy. And the problem that must be tried multiple times.

What's more, the diameter of the blood vessels is quite small, and the slight drop can not accurately cause the puncture needle to fall on the correct blood vessel, which will affect the subsequent treatment or surgery. Furthermore, as in the above-mentioned U.S. case, please refer to FIG.-1 and FIG.-2. The ultrasonic guiding device further has a closed shaft hole for fixing and passing through a needle, and the closing is utilized. The shaft hole can facilitate the positioning of the needle to perform vascular puncture with the ultrasonic wave. After the blood vessel is puncture, the steel wire or the subsequent blood vessel expansion device can be guided into the blood vessel through the needle. While performing these tasks, the needle must continue to maintain the positioning of the blood vessel. Since the needle is fitted with a closed shaft hole, the ultrasonic guiding device cannot be removed first, and only after the subsequent guiding puncture is performed. The ultrasonic guiding device can be removed together, which causes inconvenience in use; on the other hand, it is also possible to interfere with subsequent blood vessel puncture due to the volume occupancy of the ultrasonic guiding device.

The main object of the present invention is to solve the problem of the inconvenience of the prior art ultrasonic guided puncture and the lack of accuracy.

In order to achieve the above object, the present invention provides an ultrasonic guided puncture device for assisting guiding a puncture needle to obtain a blood vessel position of a living body and performing puncture, and the ultrasonic guided puncture device comprises an ultrasonic detector and a A display element rotatably coupled to the ultrasonic detector and a needle positioning aid fixed to the ultrasonic detector. The ultrasonic detector includes a detecting head for contacting and detecting the position of the blood vessel of the living body by ultrasonic waves, a holding shell connected to the detecting head, and a first one disposed on the holding shell a pivoting portion, and an image processing unit disposed in the holding housing and electrically connected to the detecting head. The display device includes a second pivoting portion pivotally connected to the first pivoting portion, and a display screen electrically connected to the image processing unit, the display screen passing through the first pivoting portion and the second pivoting portion And electrically connected to the image processing unit to obtain an ultrasonic signal of the probe and display the blood vessel position of the living body. The needle positioning aid is fixed to the ultrasonic detector adjacent to the probe to assist in positioning the puncture needle to puncture the blood vessel position of the living body.

In summary, the present invention has the following features:

1. The display component is directly disposed on the ultrasonic detector, so that the operator can intuitively perform the movement of the probe according to the ultrasonic image, thereby quickly and accurately finding the position of the blood vessel.

Second, the display component can adjust the angle of the display screen according to the viewing angle of the operator, and the operator does not need to accommodate the display position of the display screen, and can meet the needs of use.
