The Department of Oncology often requires puncture, which is to insert a puncture needle into the body cavity to extract secretions for testing. The purpose of puncture is to draw blood for testing, blood transfusion, infusion and insertion of a catheter for angiography.

[0003] However, most of the existing puncture devices extract the test fluid through a negative pressure suction biopsy needle. The biopsy needle needs to be operated with both hands to extract the test fluid. When the biopsy needle is operated with both hands, it is easy to shake, and the needle head will shift in the patient's body, causing discomfort to the patient. In addition, the biopsy needle cannot be operated with one hand, which is inconvenient to operate and has a poor use effect. Based on this, the utility model designs a minimally invasive puncture device for oncology to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the clamping block is clamped by the placement groove at the bottom of the installation tube, and the clamping block is used for clamping installation. When the clamping block is installed, the bottom of the telescopic rod contacts the plate to squeeze the airbag. When the clamped puncture needle body is inserted into the lesion site during the puncture operation, the limit rod movably installed inside the bottom of the middle tube is moved by the finger, and the limit rod releases the clamping of the clamping groove on the telescopic rod. The telescopic rod moves up through the spring, and the pressurized airbag is elastically opened to form negative pressure in the liquid storage tube.
