Background

Cervical biopsy is a biopsy of the cervix, i.e., a small piece or pieces of tissue is taken from the cervix for pathological examination to determine a diagnosis. The traditional Chinese medicine composition is mainly used for treating suspected canceration of the cervix, or suspected cancer cells in cervical scraping, or suspected specific inflammation, such as tuberculosis of the cervix and the like. Cervical biopsy allows for a definitive diagnosis, determining the treatment. The pathological diagnosis of cervical biopsy is the most reliable basis for diagnosing cervical cancer, and the pathological type and the cell differentiation degree of tumors are determined by the pathological diagnosis of cervical biopsy whether early or late cervical cancer. However, there is often a problem with cervical biopsy forceps in use: the cervical parallel biopsy forceps are easy to slip when used for grasping cervical parallel biopsy, and can finish cutting only by grasping for multiple times, and particularly, when some cervical walls are thick and tissues are hard, the cutting is more inconvenient to grasp, so that a structure needs to be designed, and when the cervical forceps grasp, the cervical parallel biopsy forceps can have a positioning effect on the cervix so as to facilitate cutting and finish cervical biopsy.
