A kind of puncture needle for clinical use in pediatrics

Abstract

The invention relates to the technical field of puncture needle application, in particular to a pediatric clinical puncture needle, including a connection mechanism, an adjustment mechanism and a protection mechanism; the threaded connection between the tube body and the connecting tube facilitates the connection between the tube body and the connecting tube. The disassembly of the space improves the convenience of cleaning; the outer wall of the connecting tube is socketed with the sleeve shaft, and the sleeve shaft and the connecting tube are slidably connected with the adjustment rod, which facilitates the adjustment of the position of the adjustment rod and the adjustment of the puncture depth of the needle The side wall of the connecting plate is fixedly connected with the fixed plate, the top of the fixed plate is fixedly connected with the movable plate through the second spring, the side wall of the connecting plate is connected with the middle part of the baffle in rotation, and the movement of the adjusting rod and the movement of the baffle The rotation is convenient to protect the tip of the needle, avoiding the problem of personal injury caused by the tip of the needle when transferring after use, and is beneficial to the protection of the needle.

Description

technical field [0001] The invention relates to the technical field of application of puncture needles, in particular to a puncture needle for pediatric clinical use. Background technique [0002] The puncture needle is a medical instrument used for tissue sampling and injection treatment of various organs such as the kidney, liver, lung, breast, thyroid, prostate, pancreas, testis, uterus, ovary, and body surface in minimally invasive surgery. It is used by modern doctors Puncture needles are developed on the basis of intravenous infusion needles and injection needles. With the progress of metal processing technology and medicine, intravenous infusion and its theory have been developed rapidly, and various types of needles for different applications have been rapidly derived. The puncture needle is just one of the small branches. Even so, there are dozens of different types, with complex structures such as cannula puncture needles, and precision and small such as cell punct...

Problems solved by technology

[0003] However, for pediatric clinical puncture needles, when performing liver surgery on children, due to the delicate skin of children, it is necessary to replace different types of puncture needles during liver surgery, which is not conducive to changing the puncture needles during use. The activeness of children may cause the needle head to fall off, which is also not conducive to cleaning the inside of the puncture needle, which may easily cause secondary pollution; and the depth of puncture cannot be adjusted during use, which increases the difficulty of the operator's work. It is easy to cause injury to the patient; and after the puncture is completed, it is easy to cause the problem of personnel being scratched by the needle when transferring the needle, which is not conducive to the protection of the needle
