Puncture needle fixing device for nephrology department

Abstract

The invention discloses a puncture needle fixing device for a nephrology department, and belongs to the field of medical auxiliary tools. The puncture needle fixing device for the nephrology department comprises a fixing belt used for being bound to a human body, a bottom plate fixed to the fixing belt and a puncture mechanism installed on the bottom plate through a damping rotating shaft, whereinthe puncture mechanism comprises a first support which sleeves the damping rotating shaft, a second support which is connected with the first support in a sliding mode through a first lead screw sliding block assembly, and a needle fixing head which is connected with the second support in a sliding mode through a second lead screw sliding block assembly and used for fixing a puncture needle; andthe first lead screw sliding block assembly comprises a first lead screw and a first guide rod which are vertically arranged on the inner side of the first support, and a first sliding block which sleeves the first lead screw in a threaded fit manner. Angle adjustment of the puncture needle can be achieved, puncture angle deviation is not likely to be caused, and therefore the workload of a medical staff can be relieved; and displacement between the puncture needle and the human body due to movement of the body of a patient in a puncture process can be prevented, and therefore accidental injuries to the patient can be avoided.

Description

technical field [0001] The invention relates to the field of medical aids, in particular to a puncture needle fixing device for nephrology. Background technique [0002] In the diagnosis of nephrology, renal puncture is an extremely important test subject. This method has high accuracy and can correct various deviations in routine test indicators. For acute nephritic syndrome, primary nephritis, rapid deterioration of renal function, and severe nephropathy who have not improved after long-term treatment, renal puncture is required to accurately identify and predict the condition. [0003] At present, in the operation of intrarenal puncture, most of the surgeons can only rely on personal experience to perform the surgery for the patient with a puncture needle. Scanning and monitoring; especially during the operation, it is necessary to strictly ensure the stability of the puncture needle to prevent accidental injuries caused by the slipping of the needle. The adjustment and...

[0003] At present, in the operation of intrarenal puncture, most of the surgeons can only rely on personal experience to perform the surgery for the patient with a puncture needle. Scanning and monitoring; especially during the operation, it is necessary to strictly ensure the stability of the puncture needle to prevent accidental injuries caused by the slipping of the needle. The adjustment and fixation of the angle of the puncture needle is not accurate enough, and it is easy to shake the hand during the puncture, resulting in a deviation of the puncture angle, which cannot achieve the expected puncture effect, which will bring a workload to the medical staff. At the same time, during the puncture, Since the puncture is performed by medical staff with a hand-held puncture needle, once the patient's body moves, the puncture needle and the human body will be displaced, resulting in accidental injury to the patient
