Description

Living body tissue examination instrument for pathology department Technical Field The utility model relates to the technical field of medical equipment, in particular to a biopsy instrument for a pathology department. Background Biopsy, i.e., pathology biopsy, is one of the important means of diagnosing diseases in modern medicine, and when a doctor finds that a lesion of a patient is abnormal or needs to further define the nature of the lesion, the doctor selects to perform pathology biopsy, obtains a lesion tissue or a lesion organ from the living body of the patient by using surgical methods such as local cutting, clamping, puncturing, scratching or cutting of a lesion organ, performs histological examination and diagnosis, and for example, when a suspicious lesion is found in enteroscopy, the biopsy forceps clamp is used to take the lesion tissue to the pathology department for examination so as to define the nature of the lesion. Pathological biopsy can determine the specific type of lesions, such as gastrointestinal biopsy can determine chronic atrophic gastritis, peptic ulcer and the like, and meanwhile, the pathological biopsy can distinguish benign and malignant tumors, thereby providing necessary basis for the treatment of clinical diseases. Along with the continuous progress of medical technology, pathology biopsy is also continuously developed, but the traditional pathology department biopsy usually adopts a mode of taking out a biopsy clip from a patient body and then carrying out holding and transferring, so that the operation process is complicated, and cross contamination is easy to cause when the biopsy clip is taken out of the patient body and then transferred and held, and the biopsy analysis structure is influenced, therefore, the application provides a pathology department biopsy instrument for meeting the requirements. Disclosure of utility model The utility model aims to solve the technical problem of providing a biopsy instrument for pathology department, which solves the problems of complicated operation process and easy cross contamination of the existing pathology biopsy mode. In order to solve the technical problems, the utility model provides the following technical scheme: The utility model provides a pathology department is with biopsy apparatus, includes the control tube, the control tube has a front end, the front end of control tube is provided with the grafting pipe, grafting pipe and sampling tube peg graft, the one end that the grafting pipe was kept away from to the sampling tube is provided with the sampling sword, the control tube is inside to have the pump chamber, the pump intracavity is provided with the subassembly of bleeding, grafting pipe switches on sampling tube and pump chamber inner space.
