Device for preventing tumour diffusion after bone tumor biopsy

Abstract

A device for preventing tumor spread after bone tumor biopsy, which belongs to medical equipment, includes a blocking body used to block the puncture needle path after biopsy, the blocking body is made of water-absorbing and expandable materials, and the outer surface Threads are provided; one end of the blocking body is the blocking end, and the maximum diameter of the blocking end is smaller than the diameter of the puncture needle; the other end of the blocking body is the operating end, and the operating end is provided with a device that can move along the axial direction of the blocking body. Insert the socket or handle of the operation wrench; the maximum diameter of the operation end is larger than the diameter of the puncture needle; the middle part of the plugging body is a concave connecting column, and the connecting column, the blocking end and the operating end are all Smooth transition; the blocking end is coated with an anticancer drug layer. It blocks the needle track left by puncture after biopsy, which can prevent local diffusion and metastasis caused by the outflow of tumor from the needle track to the surrounding of the puncture port, and has a simple structure and is easy to operate.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for preventing tumor spread after bone tumor biopsy. Background technique [0002] When performing a bone tumor biopsy, the bone tumor needs to be punctured first, and a needle tract will be left after the biopsy is taken. At present, if the left needle tract is left untreated, the tumor cells in the bone tumor will flow through the needle tract to around the puncture port , the formation of tumor spread, affect the treatment. At present, there is no device dedicated to blocking the needle path to prevent the tumor from spreading. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a device for preventing tumor spread after bone tumor biopsy, which can block the needle tract left after biopsy and prevent tumor cells from locally spreading through the needle tract. . [0004] I...
