Abstract

The invention discloses a compasses type cervical conization device. The device comprises a positioning block, an adjusting mechanism, a knife holder and a blade, wherein the positioning block is hinged with a swing rod through a hinge pin, a positioning needle is arranged below the positioning block, and a press handle is arranged above the positioning block; a support is arranged at the tail end of the swing rod, the knife holder device is mounted on the support, the blade is mounted at the lower end of the knife holder device, and the adjusting mechanism is arranged between the blade and the knife holder device. A tool is fixed firstly by the positioning block and a positioning needle head, then the swing rod is driven to rotate for a circle with the positioning block as the center, the swing rod carries the knife holder and the blade to rotate for a circle to perform conization on muscular tissue, and a conical cut block is formed. The device is simple and reasonable in structure, very convenient to operate and good in conization effect and has the size up to the standard. Different conization sizes, depths and shape standards are realized by adjusting the height, angle and longitudinal position of the knife holder.

Description

technical field [0001] The invention belongs to the technical field of tissue cutting tools for medical devices, and in particular relates to a compass type cervical cone cutter. Background technique [0002] In the daily research on soft tissue, experimenters often need to cut soft tissue with a fixed size, but soft tissue has great elasticity, especially when the soft tissue is thin, it is difficult to ensure the size of the sample after cutting by using the traditional method of cutting with a single blade sequentially. consistency. For example, when it is necessary to cut conical muscle tissue with a diameter of about 1 cm, it is difficult to ensure that the obtained size meets the standard by traditional cutting methods, which will affect the accuracy of subsequent measurements. [0003] Chinese patent document CN201521101302.4 discloses a hard tissue cutting machine, including a base, a cutter frame fixed on the base and a fixed splint, the cutter frame is hinged on t...
