Percutaneous renal puncture biopsy positioning auxiliary device

Abstract

The invention discloses a percutaneous renal puncture biopsy positioning auxiliary device. The percutaneous renal puncture biopsy positioning auxiliary device comprises a fixing base, a clamping plate, a control console, a stepping motor A, a driving gear, a rack plate, a connecting cross beam, a stepping motor B, a rotating shaft I, a rotating frame, a stepping motor C, a lead screw, an adjustingblock, a stepping motor D, a rotating shaft II, a connecting plate, a needle sleeve, a fixing frame and a handheld ultrasonic probe. Firstly, through a novel three-dimensional distance regulation andcontrol system, a needle holder can be regulated and controlled at multiple positions and multiple angles, a puncture needle can reach the optimal puncture point conveniently, secondly, exposure of an operator can be reduced in the puncture process in cooperation with the design of a built-in follow-up ultrasonic probe, the puncture needle can be accurately fed into a designated area in real time, the puncture accuracy is improved, the puncture frequency is reduced, finally, the puncture biopsy operation is facilitated, complications are reduced, a patient is well protected, and very high clinical popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of renal puncture biopsy positioning, in particular to an auxiliary positioning device for percutaneous renal puncture biopsy. Background technique [0002] Percutaneous renal biopsy is to puncture the back skin with a kidney needle under the guidance of ultrasound, and puncture the lower pole of the kidney at a selected puncture point to obtain material. It is a popular renal biopsy method at home and abroad at present. The diagnosis of chronic kidney disease is of great significance. Renal biopsy is an invasive examination, and many complications may occur: hematuria, perinephric hematoma, the incidence rate is 48-85%. The effect of patient posture coordination during nephrocentesis plays a key role in improving the success rate of puncture and reducing postoperative complications. [0003] According to the above, although clinical ultrasound-guided puncture has a good positioning effect, due to the lack...

Problems solved by technology

[0003] According to the above, although clinical ultrasound-guided puncture has a good positioning effect, due to the lack of special puncture auxiliary equipment in the existing clinical practice, medical staff generally perform needle puncture based on experience, so it is easy to cause large errors, often Multiple adjustments are required, which eventually not only takes time, but also increases the damage, which brings great hidden dangers to clinical operations. In view of this, it is necessary to design a positioning aid for percutaneous renal biopsy to solve the above problems
