A puncture needle with a spring scale

Abstract

The invention belongs to the field of medical technology, and discloses a puncture needle with a spring scale, comprising a needle body, a scale, a pressing rod, a placement tube and an arc ring, the outer surface of the needle body is provided with a scale, and the scale One side of the ruler is marked with a corresponding number, and one end of the needle body is provided with a needle tail, and the inner surface of the needle tail is attached to the outer surface of the needle body, and the needle body and the needle tail are fixedly connected. It is equipped with a scale and a pressing rod. The setting of the scale is convenient for the user to grasp the depth of the puncture well when using it. At the same time, the pressing rods arranged crosswise make the force generated by the deformation of the pressing rod make the spring One is loose, so that the designated scale can be slid. When the puncture is performed, the spring one is just attached to the patient's skin, indicating that the puncture is in place. The operation is simple and the efficiency is high, so that the user can control the depth very well, and it is not easy to produce error.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a puncture needle with a spring scale. Background technique [0002] The puncture needle is a medical device for sampling and injecting tissue from various organs such as the kidney, liver, lung, breast, thyroid, prostate, pancreas, testis, uterus, ovary, and body surface during minimally invasive surgery. [0003] The needle is usually graduated and visible on ultrasound. When in use, the needle needs to be punctured into the body, and it needs to be punctured to a designated organ or part. During the puncture process, it is necessary to use an ultrasonic instrument to observe where the puncture needle punctures, so generally speaking, the puncture needle should also have a scale so that the operator knows how deep the puncture needs to be. At the same time, the existing puncture needle has no protective device during the carrying process, which is prone to bacteria, which aff...

Problems solved by technology

When in use, the needle needs to be punctured into the body, and it needs to be punctured to a designated organ or part. During the puncture process, it is necessary to use an ultrasonic instrument to observe where the puncture needle punctures, so generally speaking, the puncture needle should also have a scale so that the operator knows how deep the puncture needs to be. At the same time, the existing puncture needle has no protective device during the carrying process, which is prone to bacteria, which affects the use. The depth cannot be well controlled during puncture. prone to errors

[0004] In addition, the existing tubes do not sterilize much of the needle tail. The present invention proposes a top cover that can facilitate the disinfection of the needle tail.
