A spreading device capable of cutting small tissue pieces for cell biopsy

Abstract

The invention relates to the technical field of auxiliary medical equipment for tissue block cutting, in particular to a stretching device for cell biopsy that can cut small tissue blocks, including an adjustment column, the outer wall of the upper end of the adjustment column is provided with an upper external thread, and the outer wall of the lower end of the adjustment column The lower external thread is provided, and the beneficial effect is: the present invention sets a rotating support rod on the outer wall of the adjustment column, uses the opening of the support rod to support both sides of the opening position, and cooperates with the extrusion of the fine-tuning block and the spring, Realize fine-tuning and buffering of the support strength, so as to avoid damage to the outer wall; by setting the lower support rod with threaded rotation, the adjustment column can be squeezed into the inner cavity of the tissue, and the vertical fixation of the support device can be realized, thereby enhancing the stability of the device To prevent the device from shaking or falling off, cooperate with the extrusion bolts in the clamping cavity to achieve further fixation with the inner wall of the opening, so that it is convenient for the staff to perform tissue extraction operations in the opening.

Description

technical field [0001] The invention relates to the technical field of tissue block cutting auxiliary medical equipment, in particular to a stretching device for cell biopsy that can cut small tissue blocks. Background technique [0002] In the process of medical experimental research, it is necessary to extract tissues from the inside of animals and plants, and the outer walls of animals and plants are protected by thicker outer walls. When cutting and extracting, the outer walls need to be cut open. [0003] When cutting in the outer wall of the incision, because the outer wall of animals and plants is elastic, it is easy to close to the opening position, so the staff needs to stretch the two sides of the opening when cutting, and the cutting tissue itself is difficult to operate At the same time, the two sides need to be stretched, which further increases the difficulty of cutting, and the existing support device has low stability, which may easily cause the opening to te...

Problems solved by technology

[0003] When cutting in the outer wall of the incision, because the outer wall of animals and plants is elastic, it is easy to close to the opening position, so when cutting, the staff needs to stretch the two sides of the opening, and the cutting tissue itself is difficult to operate At the same time, the two sides need to be stretched, which further increases the difficulty of cutting, and the existing support device has low stability, which is easy to cause the opening to tear or the support to fall off

[0004] To this end, a spreading device for cell biopsy that can cut small tissue pieces is provided to solve the problem of supporting the opening position during tissue extraction
