Abstract

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, which includes a rigid outer sheath and multiple suction cutting sampling needles. The suction-cutting sampling needle includes an outer holding needle and an inner cutting needle. The outer holding needle is provided with a concave hole for collecting and storing sampling tissues. The inner cutting needle is used for cutting the sampling tissues collected and stored in the outer holding needle. Sampling is carried out by combining suction and cutting. The suction-cutting multi-point sampling needle proposed by the present invention has multiple pre-bent inner needles, which can sample multiple parts of the tumor in one puncture sampling process, and can adapt to different conditions by replacing inner needles with different pre-bent shapes. Sampling situation. The multi-point sampling needle of the present invention ensures the effect of sampling while improving the sampling efficiency, improves the effectiveness of sampling samples, and reduces the harm caused by sampling to patients.

Description

technical field [0001] The invention belongs to the field of medical instruments, and more particularly relates to a suction-cutting multi-point sampling needle with an active deformation function. Background technique [0002] Tumor is a chronic disease that seriously endangers human health, and its greatest harm is that cell mutation leads 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 appear after the age of 40. According to statistics, the incidence of males is about twice that of women. Among them, prostate cancer and kidney cancer have very high morbidity and mortality. It is a disease that seriously endangers human health. For tumors of the urinary system, there are different coping plans according to different patients' conditions, such as surgery, radiotherapy and chemotherapy, traditional Chinese medicine treatment, etc.; if surgery is used for treat...
