Embodiment 1

[0025] see Figure 1-6 , the present invention provides the following technical solutions: a lumbar puncture needle screw positioning device, including a housing 10 and a fixing cylinder 20, the housing 10 and the fixing cylinder 20 are fixedly connected, a first cavity is opened inside the housing 10, and the inside of the housing 10 slides close to the top An electric push rod 11 is connected, and a push plate 12 is fixedly installed at one end of the electric push rod 11 close to the inside of the casing 10. The electric push rod 11 is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. The model of the push rod 11 is TJC-C1. After the electric push rod 11 moves to the fixed cylinder 20, the push plate 12 pushes the connecting rod 23, and then the needle is pushed out from the fixed plate 24 to complete the pushing work. The inside of the housing 10 is close to the push rod. One side of the plate 12...

Abstract

The invention belongs to the technical field of medical instruments, in particular to a lumbar puncture needle screw positioning device. The lumbar puncture needle screw positioning device comprises ahousing and a fixing cylinder which are fixedly connected, a first chamber is opened in the housing, an electric push rod is slidably connected to the inside of the housing close to the top, a push plate is fixedly mounted on an end of the electric push rod near the inner portion of the housing, and a blocking plate is fixedly disposed on one side of the inner portion of the housing near the pushplate, and a connecting seat is fixedly disposed on an outer side wall of the housing; a rebound seat is arranged at inner portion of the fixed cylinder the near the top, after the user fixes the needle to a fixed disc, the electric push rod drives the push plate to move toward the fixed cylinder, and drives the connecting rod to slide to push the needle out of the fixed disc. Through the elasticforce of several springs inside the rebound seat, the connecting rod can return to an original position autonomously, the original manual adjustment of the connecting rod is changed, a needle insertion step can be simplified, and the effect of the needle wearing by the user is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a screw positioning device for a lumbar puncture needle. Background technique [0002] It is a commonly used clinical diagnosis and treatment operation. It can be used to diagnose various inflammatory diseases of the central nervous system, vascular diseases, spinal cord lesions, suspected intracranial space-occupying lesions, undiagnosed nervous system diseases, pneumocephalus, myelinography, etc.; also used for cerebrospinal fluid pressure High liquid discharge (decompression) and injection of drugs to treat central nervous system diseases; before lumbar puncture, it should be noted that if the local skin, soft tissue, and bone are inflamed, the puncture should not be performed; those with obvious intracranial pressure and signs of brain herniation should not puncture; the condition is critical Those who are in shock or on the verge of shock cannot be punct...
