A biopsy sampler for digestive tract tumors

Abstract

The invention discloses a biopsy sampler for digestive tract tumors. The biopsy sampler comprises a movable platform arranged above a sickbed, wherein an installation assembly for being fixed to the sickbed is arranged below the movable platform, a puncture needle for penetrating through digestive tract is connected above the movable platform, and is installed in a lifting mechanism arranged on the movable platform, the top plate of the lifting mechanism is connected with a pump suction assembly for sucking a tumor tissue fluid, and the pump suction assembly is connected with the lifting mechanism through a transmission mechanism. According to the invention, the top plate and the telescopic member vertically ascend and descend along the inner wall of the sleeve member to drive the punctureneedle to vertically ascend and descend into a patient, the one-way transmission assembly is driven to work under the action of the gear and the fixed spur rack during the ascend and descend of the top plate and the puncture needle, the one-way transmission assembly drives the blade wheel in the micro pump to rotatably suck the tumor tissue fluid when the puncture needle moves downwards to be inserted into the tumor, and the micro pump does not work when the puncture needle moves upwards, so that the puncture and biopsy sampling integrated function is achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to a digestive tract tumor biopsy sampler. Background technique [0002] Tumor biopsy is to take a small amount of tissue from the patient's tumor site (according to different situations, methods such as forceps, cutting, resection, or puncture suction can be used) to make pathological sections, observe the morphology of tumor cells and tissue structures under a microscope, and determine the tumor's status. The nature, histological type and degree of differentiation provide a reliable basis for clinical treatment. [0003] In the process of gastrointestinal tumor biopsy, the secretions are extracted through the puncture needle through the tumor in the body cavity for testing. Most of the existing gastrointestinal tumor biopsies need to be completed in two steps. Aspirating tumor tissue fluid for biopsy sampling is cumbersome. Contents of the invention [0004] Based on the deficiencies in the...
