Kidney puncture device for nephrology to avoid needle handle slipping during use

Abstract

The invention provides a kidney puncture device for nephrology which prevents the needle handle from slipping off during use. A vertical plate inserted into the fastening plate is fixed, airbag one is fixedly installed on the side of the backing plate close to the twist ring, a wedge-shaped block is fixedly connected to the inner wall of the twist ring, and airbag two is fixedly installed under the fastening plate, and the second airbag passes through The hollow ring and the ventilation tube are connected with the first air bag. When the twisted ring is rotated, the wedge-shaped block squeezes the fastening plate and the second air bag at the same time. The fastening plate is protruded inward and is pressed against the outer wall of the puncture needle handle to enhance the stability of the puncture needle handle. The gas in the second airbag is squeezed into the first airbag, and the volume of the first airbag becomes larger. Continue to push the fastening plate to further strengthen the clamping firmness. By setting the hollow ring, different airbags can be adjusted to ensure All fastening plates rest on the needle shaft.

Description

technical field [0001] The invention belongs to the technical field of kidney puncture, in particular to a kidney puncture device for nephrology which prevents the needle handle from slipping off during use. Background technique [0002] Due to the wide variety of kidney diseases and the complex etiology and pathogenesis, the clinical manifestations of many kidney diseases are not completely consistent with the histological changes of the kidney. At this time, kidney puncture is required for inspection. The installation of the handle is not particularly firm, and the needle handle slips easily during the kidney puncture, which affects the normal inspection work. [0003] Patent authorization announcement number CN 209713076 U proposes a new kidney puncture assistant for nephrology, including a support rod, a fixed air bag, a slider and a pneumatic control valve, through which the two fixed air bags are inflated and deflated, thereby Fixing the puncture needle can effectivel...
