Abstract
The utility model relates to an improved pleural biopsy needle which comprises an outer needle tube and an inner needle tube. The inner needle tube is installed in the outer needle tube in a sliding mode. A tailstock of the outer needle tube is provided with grooves, and the two grooves are formed in the two sides of the tailstock respectively. Fulcrum bars are installed in the grooves respectively in a rotating mode, the other end of each fulcrum bar is installed on a base in a rotating mode, and the base is fixedly installed on the upper portion of a sucker. A positioning plate is arranged in one fulcrum bar, a bolt is installed on the positioning plate in a rotating mode, and the base is provided with a screw hole corresponding to threaded rod of the bolt. The improved pleural biopsy needle has the advantages that the outer needle tube of the biopsy needle is fixed through the sucker and other parts, when the biopsy needle is used, the sucker is sucked on the part of the thoracic cavity, and then the biopsy needle is fixed by installing one end of the bolt into the screw hole. In this way, the biopsy needle is convenient to use.
Description
Technical field
This utility model relates to a kind of Pleura biopsy needle of improvement, belongs to field of medical products.
Background technology
Sampling check to pleura clinically, conventionally adopt biopsy needle to sample, but its drawback is, outer needle tubing for biopsy needle does not have special fixture, cause being easily moved in the process of operation, have potential safety hazard, nor easily operation.
Summary of the invention
For overcoming the defect of prior art, this utility model provides a kind of Pleura biopsy needle of improvement.The technical solution of the utility model is: a kind of Pleura biopsy needle of improvement, comprise outer needle tubing and inner needle tube, the inside that is arranged on outer needle tubing that described inner needle tube slides, on the tailstock of described outer needle tubing, be provided with groove, two grooves are separately positioned on the both sides of tailstock, that in each groove, all rotates is provided with pole, what the other end of this pole rotated is arranged on base, described base is fixedly mounted on the top of sucker, the inside of a pole is provided with location-plate therein, what bolt rotated is arranged on location-plate, on described base, be provided with the screw corresponding with the screw rod of bolt.
On described outer needle tubing and inner needle tube, all mark has scale.
The utility model has the advantages that: the outer needle tubing of biopsy needle is fixed by parts such as suckers, when external needle tubing is fixing, sucker is adsorbed on to the position in thoracic cavity, be then arranged in screw by the end of bolt, realize the fixing, easy to use of outer needle tubing.
