Disposable mammary gland biopsy needle processing and assembling process

Abstract

A disposable mammary gland biopsy needle machining and assembling process disclosed in the invention comprises the following steps: S1, an outer knife pipe with a lateral negative pressure hole is prepared and machined, and the proper pipe length is cut; S2, after cutting is completed, a pipe sampling hole is cut through laser, and the lateral negative pressure hole is punched through laser; S3, an acid solvent is adopted for cleaning the punched pipe to remove burrs; S4, while steps S1 to S3 are carried out, an outer cutter pipe lateral negative pressure channel pipe is prepared, the proper pipe length is cut, the pipe is sliced, and burrs are removed; S5, the two pipes are subjected to laser welding forming, and ultrasonic welding is conducted after assembling; S6, injection molding of apuncture blade coupler B and injection molding of a puncture blade coupler A are carried out; and S7, edge grinding and stamping procedures are conducted, and then the blade is punctured to completethe assembly process. The biopsy needle has a puncture sensing function, the uniformity of cutting force is guaranteed to the maximum extent while cutting is conducted, the internal wound surface is prevented from being too large, then biopsy samples are uniform in size, and pathological analysis is facilitated.

Description

technical field [0001] The invention relates to the technical field of breast biopsy, in particular to a process for processing and assembling a disposable breast biopsy needle. Background technique [0002] Most breast diseases can lead to the formation of breast tumors, including benign lesions such as fibroadenoma and intraductal papilloma, and malignant lesions such as breast cancer and breast sarcoma. Certain infectious or proliferative breast diseases such as acute mastitis and hyperplasia of the mammary glands (mammary gland disease, cystic hyperplasia) are often accompanied by the formation of breast masses. Some require only conservative treatment, while others require surgical resection, biopsy for diagnosis, and treatment. If it is a malignant tumor, such as breast cancer (ie breast carcinoma in situ), the vast majority can be cured. The best way to improve the cure rate of breast cancer is to realize early detection, early diagnosis and early treatment of breas...
