Plate type fixator for percutaneous kidney puncture biopsy

Abstract

The invention discloses a plate type fixator for percutaneous kidney puncture biopsy. The plate type fixator comprises a fixed plate, an avoidance hole, a slide rail, a first insert hole, a clamping plate, a fixed sleeve, a first bolt, a first spring, a connecting plate, a second insert hole, a cutting ferrule, a second bolt, a second spring, a guide plate, a guide hole and an adjusting sleeve. The plate type fixator for percutaneous kidney puncture biopsy is skillful in structure and powerful in function. Firstly, by means of action of an adjusting guiding mechanism, the fixator can be adjusted conveniently according to an aspiration biopsy position of a patient, and the puncturing accuracy can be also improved greatly and the stability of a sucking and sampling process can be enhanced; secondly, by means of a matched effect of multiple fixed connecting mechanisms, the fastness of the device and the body of the patient is improved, the condition that the patient moves or the device isfar from the body of the patient is avoided, and finally, the success rate of the percutaneous kidney puncture biopsy is enhanced greatly, so that the fixator is favorably popularized and applied inmedical industry.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a plate-type fixator for percutaneous renal biopsy. Background technique [0002] Percutaneous renal biopsy is the use of a kidney needle through the skin of the back under the guidance of ultrasound, and the selected puncture point is punctured into the lower pole of the kidney to obtain materials. It is currently a popular kidney biopsy method at home and abroad. It is suitable for primary disease, secondary or genetic The diagnosis of sexual kidney disease is of great significance. Renal biopsy is a traumatic examination, which can cause many complications: hematuria, perinephric hematoma, the incidence of which is 48-85%. The effect of patient position coordination during renal puncture plays a key role in improving the success rate of puncture and reducing postoperative complications. [0003] According to the above, during the operation, it is necessary to arrange a dedi...

Problems solved by technology

[0003] According to the above, in the existing conditions, it is necessary to arrange special nursing staff to communicate with the patient during the operation, press the legs, and keep the patient in a relatively static position. However, due to the patient's nervousness, fear, and involuntary reactions, often in the kidney. At the moment when the needle is inserted, the patient will suddenly change the position, which will catch the nurses by surprise, affect the success rate of renal biopsy, and even cause hematoma around the kidney, with large amount of bleeding, which is life-threatening

Therefore, under the existing conditions, not only the manpower input in the process of percutaneous renal biopsy is large, but also the risk is extremely high. In view of the above defects, it is necessary to design a plate type fixer for percutaneous renal biopsy
