Child lumbar puncture positioning and fixing device and using method thereof

Abstract

The invention belongs to the technical field of medical instruments, and relates to a child lumbar puncture positioning and fixing device and a using method thereof. The main structure of the device comprises an iliac spine positioning patch, a length adjusting buckle, a length adjusting belt, a length adjusting buckle switch, a length adjusting belt handle, a puncture fixing frame, spine positioning points, sliding rails, a large support, a T-shaped puncture sleeve, a small support, a spinous process positioning suction cup, a puncture needle, a puncture needle core, a fixing lantern ring, afixing clamping groove support, a buckle push rod, a fixing lantern ring locking switch, a fixing clamping groove, a suction cup connecting arm, a sliding block and small support telescopic rods, wherein the spine positioning points are arranged on the two sides of the puncture fixing frame respectively, the sliding rails are correspondingly arranged on the other two sides of the puncture fixing frame respectively, the small support telescopic rods are installed at the two ends of a cross rod of the small support respectively, and the spinous process positioning suction cup is fixedly arrangedat the other end of the suction cup connecting arm. The positioning puncture point is accurately and rapidly determined, the puncture stability is improved, the puncture success rate is increased, the psychological fear of a child patient is relieved, operation and popularization are convenient, and the application environment is friendly.

Description

Technical field: [0001] The invention belongs to the technical field of medical devices, and relates to a positioning and fixing device for lumbar puncture in children and a use method thereof, in particular to an auxiliary positioning and fixing device for accurately and quickly locating a puncture point and improving puncture stability and a use method thereof. Background technique: [0002] Pediatric lumbar puncture is a common operation method for diagnosing children's central nervous system diseases in clinical diagnosis and treatment. In the past, when puncture was positioned, clinicians needed to roughly judge the position of puncture by palpation with fingers, which had high requirements for clinical experience. Many The puncture failed due to the inaccurate positioning of the junior doctor or the instability of the hand-held needle puncture during the operation. Manually holding the puncture needle is difficult to puncture, the work intensity of the medical staff is ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and propose to design a positioning and fixing device for lumbar puncture in children and its use method to solve the difficulty of hand-held needle tube puncture , the problem of inaccurate positioning, solve the problem of long puncture time and aggravate the pain of patients, overcome the disadvantages of existing puncture methods that rely on clinical experience and poor puncture stability, avoid the phenomenon that large auxiliary devices may easily cause psychological fear in children, and improve the success of puncture rate and work efficiency
