Pediatric kidney puncture needle

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to a pediatric kidney puncture needle. The pediatric kidney puncture needle comprises a needle tube and a puncture needle head; a conical needle base is arranged at the lower end of the needle tube, and the needle base is sleeved with a blind tube; the lower end of the needle tube is sleeved with a triangular bracket, and the lower ends of supporting legs of the triangular bracket are sleeved with rubber suction cups; the middle of the outer side of the needle tube is sleeved with a rubber grabbing sleeve; a sealing block is arranged at the bottom of an inner cavity of the needle tube, and a piston is arranged in an inner cavity of the needle tube; the puncture needle head is arranged on thelower end face of the piston, and the lower end of the puncture needle head penetrates through the sealing block to penetrate through the needle base and is arranged in the blind tube; a piston rod isarranged in the middle of the upper end of the piston, and the end, away from the piston, of the piston rod is in threaded connection with a pushing plate; the outer side of the upper end of the needle tube is in threaded connection with a pushing mechanism. According to the pediatric kidney puncture needle, handheld operation is more convenient, the puncture depth of kidney biopsy is convenientto control, and meanwhile the bad influence caused when children move around during puncture biopsy on biopsy is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pediatric kidney puncture needle. Background technique [0002] Kidney puncture needles are often used in the detection of kidney disease. Usually, doctors perform blind puncture through years of experience. With the development of ultrasound technology, the use of ultrasound equipment for detection can greatly improve the accuracy of puncture, especially due to children's body comparison Fragile and small in size, it is easy to insert too little or too much, which causes pain for the patient and is not conducive to medical diagnosis. At the same time, the traditional puncture needle is hand-held, which is not only difficult to apply force but also difficult to grasp, and children in the puncture biopsy Crying and making noise from time to time can easily cause the puncture needle to break or change the puncture angle, resulting in inaccurate changes in the puncture...
