Embodiment approach

[0027] The subject of protection of the present invention and embodiment are as follows:

[0028] The invention provides an improved lumbar-hard joint lumbar puncture needle, such as Figure 1 to Figure 7 As shown, it includes an operating handle 3, a needle feeding mechanism, a needle feeding controller, and a drainage governor. Through hole, the end is located in the fixed through hole, and the right side of the end is in contact with the needle-introduction controller, and the needle-introduction controller is matched with the fixed through-hole to realize the end of the needle-introduction mechanism in the fixed through-hole. fixed; the side of the operating handle 3 is provided with a drainage interface 24, and the drainage governor cooperates with the drainage interface 24 to realize the control of cerebrospinal fluid drainage.

[0029] The needle insertion mechanism includes an epidural puncture needle 1, a lumbar anesthesia puncture needle 4, and a needle core 5, and ...

Abstract

The invention provides a modified combined spinal-epidural lumbar spinal needle, which comprises an operating handle, a needle insertion mechanism, a needle insertion controller and a drainage speed regulator, wherein the needle insertion controller cooperates with a fixing through hole of a grab handle; the fixation of an end of the needle insertion mechanism in the fixing through hole is realized; the drainage speed regulator cooperates with a drainage interface of the grab handle; the drainage control of cerebrospinal fluid is realized. A spiral fine tuning principle is utilized for the modified combined spinal-epidural lumbar spinal needle; through cooperatively designing the needle insertion mechanism and the needle insertion controller, the control of needle insertion precision in combined spinal-epidural puncturing operation is realized; meanwhile, through designing corresponding automatic pressure measuring and drainage speed regulating mechanisms, the corresponding pressure measuring and drainage operation is realized; the combined spinal-epidural lumbar spinal needle has the advantages that the needle insertion precision is high, the control operation is realized simply and conveniently, the automatic pressure measurement can be achieved, the drainage speed is flexibly controlled, and the like.

Description

technical field [0001] The invention relates to the field of medical aids for lumbar puncture, in particular to an improved lumbar-hard combined lumbar puncture needle. Background technique [0002] Lumbar puncture is a common basic operation technique in clinical practice. In order to complete the drainage, sampling, pressure measurement and other operations of cerebrospinal fluid, lumbar puncture is mostly used to puncture the lumbar spine. At present, most common lumbar puncture needles are composed of a lumbar puncture needle and an inner core of the lumbar puncture needle. During use, the inner core of the lumbar puncture needle is pulled out to realize the drainage of cerebrospinal fluid, so as to complete the follow-up operation. However, due to structural reasons, the drainage speed of cerebrospinal fluid cannot be controlled, which may easily cause a large outflow of cerebrospinal fluid, and there is a risk of complications. At the same time, lumbar puncture has hi...
