A novel biopsy extractor system for the department of orthopaedics comprises an extractor and a switcher. The extractor comprises a head and a needle cylinder, the head is provided with an extracting passage, the needle cylinder is connected at the bottom end of the head and communicated with the extracting passage, a switching connection port communicated with the extracting passage is arranged on the top surface of the head, a plurality of grabbing teeth are distributed on the bottom surface of the needle cylinder evenly, and a barb groove is formed in the lower portion of the needle cylinder. The switcher comprises a switching connector, a storage cylinder and a suction apparatus connector, the switching connector fits the switching connection port and is provided with an entering passage, and the storage cylinder is detachably connected between the switching connector and the suction apparatus connector. The novel biopsy extractor system for the department of orthopaedics has the advantage that the needle cylinder grabs pathological tissues through the grabbing teeth and the barb groove, can grab more pathological tissues through the grabbing teeth than a common needle cylinder and can grab pathological tissues through the barb groove when extracted, and accordingly the pathological tissues extracted by doctors during a spinal operation of the department of orthopaedics can meet clinical examination requirements.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a novel orthopedic biopsy extractor system. Background technique [0002] Biopsy, also known as surgical pathological examination, refers to the removal of pathological tissue from the patient's body by cutting, forceps or puncture in response to the needs of diagnosis and treatment for pathological examination. At present, in orthopedic spine surgery, it is sometimes necessary to remove pathological tissue, and the current biopsy removal system used in orthopedic spine surgery generally includes a extractor and a converter. The syringe of the extractor is mainly used to grab pathological tissue. The structure of the syringe of the current extractor is relatively common, and the amount of pathological tissue taken out in the operation is very small, which is difficult to meet the needs of clinical examination. The applicant has studied with great concentration for above weak point...
