Publication number: 20230200879Abstract: An impedance detection device for a living body and a radiofrequency ablation frequency are provided. The detection device includes an excitation-signal generation unit, a transmission unit, an impedance-signal acquisition unit, and a processing unit. The excitation-signal generation unit is configured to generate and output a high-frequency excitation signal. The transmission unit is configured to transmit the high-frequency excitation signal to a detection site of the living body via an output port of the transmission unit, where the output port of the transmission unit forms an impedance-signal detection point. The impedance-signal acquisition unit is configured to acquire a sampling signal from the impedance-signal detection point in real time.Type: ApplicationFiled: March 1, 2023Publication date: June 29, 2023Inventors: Daoyang LIU, Xiongzhi WANG, Shanfeng HU, Xinjiong QIU

Publication number: 20220338919Abstract: An integrated ablation needle (100), comprising a cannula (10) and an electrode needle (20) that is movably and penetratingly installed within the cannula (10); the electrode needle (20) comprises a needle tip (21) located at the far end and a needle rod (23) connected to the near end of the needle tip (21); at least a portion that is near to the needle tip (21) of the needle rod (23) is provided with a sampling groove (231); and the far end of the cannula (10) is provided with a cutting edge (11). The cannula (10) moves along the axial direction relative to the needle rod (23) so as to expose or cover the sampling groove; when the sampling groove (231) is exposed, a tissue portion around the needle rod (23) enters the sampling groove (231); and when the sampling groove (231) is covered, the cutting edge (11) cuts off tissue inside and outside of the sampling groove (231), such that the tissue within the sampling groove (231) is acquired as a biopsy sample.Type: ApplicationFiled: June 27, 2022Publication date: October 27, 2022Applicant: HANGZHOU NUO CHENG MEDICAL INSTRUMENT CO., LTD.Inventors: Xinjiong QIU, Baidong WANG, Tingchao ZHANG, Bobo PENG, Liwen LIU

Patent number: 11013553Abstract: The present disclosure provides a treatment method for hypertrophic cardiomyopathy applied to an ablation system comprising an ablation needle assembly and an energy generating device coupled to the ablation needle assembly. The treatment method comprises: advancing a distal end of the ablation needle assembly from an outside of a body through an intercostal and a cardiac apex into a ventricular septum; turning on the energy generating device, and using the distal end of the ablation needle assembly to perform radio-frequency ablation or microwave ablation to hypertrophied myocardium within the ventricular septum to make it necrotic and/or atrophic. The present disclosure avoids risk and pain of surgical septal myectomy and extracorporeal circulation in surgical resection, and does not have risk of large-area myocardial infarction caused by alcohol ablation. It is easy to operate and slight trauma to patients.Type: GrantFiled: November 28, 2018Date of Patent: May 25, 2021Assignee: HANGZHOU NUO CHENG MEDICAL INSTRUMENT CO., LTD.Inventors: Liwen Liu, Tingchao Zhang, Yang Li, Bobo Peng, Xinjiong Qiu
