Kidney puncture device capable of avoiding slipping of needle handle in using process for nephrology department

Abstract

The invention provides a kidney puncture device capable of avoiding slipping of a needle handle in the using process for the nephrology department. The device comprises a puncture needle handle and amounting sleeve; fastening plates which are uniformly distributed are movably inserted into the inner wall of the mounting sleeve; a vertical plate inserted into the fastening plate is fixed in the mounting sleeve; an airbag I is fixedly mounted on one side, close to a torsion ring, of a base plate; a wedge-shaped block is fixedly connected to the inner wall of the torsion ring; an air bag II is fixedly mounted below the fastening plate; the air bag II is communicated with the air bag I through a hollow ring and a breather pipe; by rotating the torsion ring, the wedge-shaped block extrudes thefastening plates and the air bag II at the same time; the fastening plate extends towards the inner side and is abutted against the outer wall of the puncture needle handle, and the stability of thepuncture needle handle is enhanced; air in the air bag II is extruded into the air bag I, the size of the air bag I is increased, the fastening plates continue to be pushed, and the clamping firmnessis further enhanced; different air bags I can be adjusted by arranging the hollow ring, and it is guaranteed that all the fastening plates can be abutted against the puncture needle handle.

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...

[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 effectively fasten the puncture needle and prevent the needle handle from slipping, but this solution requires additional components such as an air pump and connecting cables, which not only has a complex structure, more equipment, and high cost, but also The connecting cables installed will also affect the actions of medical staff, which is inconvenient to use
