Device for preventing tumor spread after bone tumor biopsy

Abstract

The invention discloses a device for preventing tumor spread after bone tumor biopsy, and belongs to the technical field of medical apparatuses. The device comprises a puncture needle, a sleeve and asampling needle; a sampling coil is fixedly connected to the outer wall of the sampling needle, multiple sampling scraping barbs are fixedly connected to the side wall of the sampling coil, a temporary storage cavity is formed in the sampling needle and located at the bottom of the sampling coil, and the puncture needle sleeves the outer wall of the sampling needle. A sealing platform is fixedly connected to the top of the puncture needle, a liquid injection channel is formed in the middle of the sealing platform, a rubber ring is fixedly connected to the end of the liquid injection channel, asealing gasket is fixedly installed at the junction of the sampling needle and the puncture needle, a sleeve sleeves the outer wall of the puncture needle, a positioning device is fixedly connected to the top of the sleeve, a push needle is matched in an inner cavity of the puncture needle, a fixed needle is fixedly connected to the end of the push needle, and a plug sleeves the outer wall of thefixed needle. By means of the device, the puncture depth is conveniently controlled. Examination tissue cannot shed or get lost, and the puncture success rate is increased. The plug absorbs drugs toplug a puncture channel, a needle passage is subjected to bleeding stopping, and tumor spread is prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for preventing tumor spread after bone tumor biopsy. Background technique [0002] When doing bone tumor biopsy for bone tumor patients, it is necessary to puncture the bone tumor first, and take out a small amount of tissue from the lesion of the patient (according to different situations, methods such as forceps, cutting, excision, or puncture suction can be used) to make pathological sections , observe the morphology of tumor cells and tissue structures under a microscope, determine the nature, histological type and degree of differentiation of the tumor, etc., and provide a reliable basis for clinical treatment. When performing a bone tumor biopsy, it is necessary to puncture the bone tumor first. During the puncture process, because patients feel differently, it is difficult to grasp a good puncture strength and puncture depth, and a needle track will be lef...

Problems solved by technology

[0004] The purpose of the present invention is to provide a device for preventing tumor spread after bone tumor biopsy, to solve the above-mentioned background technology in the process of puncture, because patients feel differently, so it is impossible to grasp the depth of puncture, and after taking biopsy A needle track will be left. If the left needle track is left untreated, the tumor cells in the bone tumor will flow around the puncture port through the needle track, forming tumor spread and affecting the treatment.
