Abstract

The invention relates to the technical field of medical apparatus and instruments, and provides a bone tumor windowing biopsy device. The device comprises a sampling mechanism used for conducting windowing sampling on a bone tumor; a sampling mechanism which is used for windowing sampling, wherein the limiting mechanism is used for guiding and limiting the sampling mechanism, the limiting mechanism is connected with the sampling mechanism, the limiting mechanism comprises a fixing assembly and a limiting assembly, the fixing assembly is used for positioning windowing sampling, the limiting assembly is used for guiding the sampling mechanism, and the fixing assembly is connected with the limiting assembly. Through arrangement of the sampling mechanism, the fixing assembly and the limiting assembly, the sampling mechanism is limited by the fixing assembly and the limiting assembly during windowing sampling, the sampling mechanism cannot deviate during sampling, and the opening position is accurate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone tumor window biopsy device. Background technique [0002] Bone fenestration technology has been widely used in experiments and clinics. In clinical practice, bone fenestration is the first step when it comes to biopsy of bone tumors or bone diseases. [0003] Clinically, bone fenestration is mainly to use Kirschner wires to drill multiple holes along the edge of the area to be fenestrated, and then knock off the area to be fenestrated. Patients have large wounds and uneven wounds, and postoperative recovery is painful. At present, there is a method of using an external rotating part to drive a window biopsy device to perform window sampling. [0004] However, the structure of the existing window biopsy device is relatively simple, and the window biopsy device is prone to offset when the window is sampled, which will cause inaccurate opening position and irregular...
