Abstract

The invention provides a biopsy rotary cutting device, which comprises a dynamic sealing structure arranged on the outer side of an inner cutter tube; the dynamic sealing structure forms a cavity outside the inner cutter pipe; the inner cutter pipe comprises a first pipe section and a second pipe section, wherein the outer diameter of the second pipe section is smaller than the outer diameter of the first pipe section; a sealing ring is arranged in the dynamic sealing structure; the cavity comprises a first cavity and a second cavity; when the inner cutter pipe moves to a first position alongthe axial direction of the inner cutter pipe, the sealing ring is positioned at the outer side of the second pipe section; an inter-cavity gap is formed between the sealing ring and the second pipe section so as to communicate the first cavity and the second cavity. According to the biopsy rotary cutting device, the atmosphere can be introduced to form the circulating airflow with better suction strength; the circulating airflow can more efficiently send the rotary-cut tissue of the corresponding position to a sample collector at the rear end, so that the sample yield is effectively improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a biopsy rotary cutting device. Background technique [0002] The biopsy rotary cutting device is widely used in minimally invasive surgical puncture operations. First, the use of the puncture head can ensure that the surgical trauma is small and does not require stitches. It can not only meet the requirements of diagnosis and treatment, but also ensure the beautiful appearance, especially for some breast Or the face, etc., the wound surface is small and easy to heal, the remaining scars are small, the damage is small, and the recovery is fast, so it is more popular with most female friends. Vacuum-assisted breast sample biopsy and rotary excision are currently one of the most effective methods for breast biopsy surgery. It is necessary to repeatedly cut suspicious breast lesions to obtain enough breast histological samples for early detection and diagnosis of breast cancer. D...
