Abstract

The invention discloses an automatic radiofrequency ablation negative pressure biopsy system. The automatic radiofrequency ablation negative pressure biopsy system comprises an outer sleeve pipe, an automatic negative pressure biopsy needle, a radiofrequency ablation needle, an injector, an insulating layer, a length scale indicator, a tail handle, a main body, an air pumping pipe, a blade guide rail groove, a soft connecting rod, a sharp blade, a cutter clamping buckle, a pressure sensor, a sampling opening and a spring. The automatic radiofrequency ablation negative pressure biopsy system largely improves the effective rate of pathological biopsy, and avoids needle passage bleeding and needle passage tumor planting to the maximum extent. The negative pressure biopsy system can guarantee that the activity of tissue is not polluted by bacteria, an ideal radiofrequency ablation effect is realized, operation is simple and rapid, and work intensity of medical workers is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a negative pressure automatic biopsy system for radiofrequency ablation. Background technique [0002] Radio frequency is a high-frequency vibration with a frequency of 150,000 times per second. The human body is a complex structure composed of many organic and inorganic substances. The body fluid contains a large number of dielectrics, such as ions, water, colloidal particles, etc. The human body mainly relies on the movement of ions to conduct current. Under the action of high-frequency alternating current, the ion concentration change direction changes back and forth with the current direction as positive and negative half cycles. Under high-frequency oscillation, the ions between the two electrodes move rapidly along the direction of the electric force line, gradually changing from a moving state to a vibrating state. Due to the different sizes, masses, charges and ...
