Abstract

The invention belongs to the field of medical equipment, and particularly relates to a suction cutting type multipoint sampling needle with an active deformation function. The suction cutting type multipoint sampling needle with the active deformation function comprises a rigid external sheath and a plurality of suction cutting sampling needles. Each suction cutting type sampling needle comprises an outer containing needle body and an inner cutting needle body, a concave hole is formed in the outer containing needle body for collecting and storing tissue samples, the inner cutting needle body is used for cutting the tissue samples collected and stored in the outer containing needle body, and sampling is conducted in a suction and cutting combined mode. The suction cutting type multipoint sampling needle provided by the invention is provided with a plurality of pre-bent inner needles, multiple parts of a tumor can be sampled in a one-time puncture sampling process, and the suction cutting type multi-point sampling needle can adapt to different sampling conditions by replacing the inner needles with different pre-bent shapes. According to the multipoint sampling needle of the invention, the sampling efficiency is improved, meanwhile, the sampling effect is ensured, the effectiveness of sampling samples is improved, and injuries caused by sampling to patients are relieved.

Description

technical field [0001] The invention belongs to the field of medical devices, and more specifically relates to a suction cutting multi-point sampling needle with active deformation function. Background technique [0002] Tumor is a chronic disease that seriously endangers human health. The greatest harm is that cell mutations lead to organ failure and death. Tumors that occur in any part of the urinary system are collectively referred to as urinary system tumors. Urinary system tumors often occur after the age of 40. According to statistics, the incidence rate of men is about twice that of women. Among them, prostate cancer and kidney cancer have a very high incidence and death It is a disease that seriously endangers human health. For tumors of the urinary system, there are different treatment plans depending on the patient's condition, such as surgery, radiotherapy and chemotherapy, and traditional Chinese medicine treatment; if surgery is used for treatment, biopsy sampl...
