Abstract

The invention relates to the technical field of medical devices, and discloses a puncture angle adjustment device and a puncture auxiliary robot. The puncture angle adjustment device includes a base, a screw mechanism and a connecting rod mechanism arranged on the base; the screw mechanism includes a screw and a connecting rod mechanism. The nut is sleeved on the lead screw; the lead screw is rotatably arranged on the base around the axis of the lead screw to drive the nut to move linearly along the axis of the lead screw; the linkage mechanism includes a transmission block, a push rod and a rotary rod , one side of the drive block is connected to the nut, and the other side of the drive block is rotatably connected to one end of the push rod; the other end of the push rod is rotatably connected to the first connection end of the rotary rod, and the second connection end of the rotary rod rotates Connected to the base, the third connecting end of the rotary rod is used for connecting the puncture needle assembly. The puncturing angle adjusting device can realize the continuous adjustment of the puncturing angle by setting a screw mechanism and a link mechanism, and has the advantages of high angle adjustment precision, long service life, compact structure and small volume.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a puncturing angle adjusting device and a puncturing assistant robot. Background technique [0002] Ultrasound-guided vascular puncture is widely used in diagnostic and auxiliary operations that require long-term injection of drugs, blood or nutrient solutions, as well as hemodynamic monitoring and venous pressure monitoring. Since the puncture operation requires high skill levels of medical staff, the success rate of puncture mainly depends on the level of medical skills of doctors, and the success rate of initial puncture is low, and the puncture angle of the puncture bracket used in puncture surgery is generally set to a fixed number of angles. To achieve a wide range of continuous adjustment. An existing infrared-guided ultrasonic positioning venipuncture system includes an ultrasonic positioning unit, a base, and a support rod arranged on the base. The ultrasonic po...
