Abstract
The utility model relates to a disposable sterile puncture needling instrument for early lung cancer diagnosis. The disposable sterile puncture needling instrument is characterized in that an arc-shaped bent pipe is embedded in a fixing block, a limiting check block is arranged at a joint of the arc-shaped bent pipe and the bottom of the fixing block, a puncture needle is arranged in the arc-shaped bent pipe, a piston head is fixed to the middle of the puncture needle, one end of the puncture needle extends out of a medical silica gel layer along the extension direction of the arc-shaped bent pipe, the other end of the puncture needle extends out of an end surface of the fixing block, a nipping handle is arranged at the other end of the puncture needle, an air outlet hole is formed in a position between the upper surface of the fixing block and the arc-shaped bent pipe, and a press groove is formed in the middle of the upper surface of the fixing block. The disposable sterile puncture needling instrument has the advantages that the disposable sterile puncture needling instrument is simple in structure and reasonable in design, a user can accurately find an entry point when operating the disposable sterile puncture needling instrument, presses the press groove by the thumb of one hand, and enables the puncture needle to carry out puncture actions by the other hand via the nipping handle, and the disposable sterile puncture needling instrument is firm and reliable; airflow among air gaps can be exhausted via the air outlet hole, and accordingly the disposable sterile puncture needling instrument is simple and is high in efficiency.
Description
Technical field
This utility model relates to the disposable sterilized puncture needle of a kind of pulmonary carcinoma early diagnosis.
Background technology
In known technical field, lung cancer pathology diagnosis is the goldstandard of pulmonary carcinoma early diagnosis, the U.S. in 1886. scholar Menetria proposes Transthoracic Biopsy pathological diagnosis pulmonary carcinoma first.The clinical medicine practise of more than 100 year proves, this project technology is effective, but at home and abroad not yet generally carried out so far, crucial problem is because pleural space is that negative pressure and lungs must ceaselessly move with breathing, the never location instrument of practicability and effectiveness and the with it puncture needle of supporting reasonable science so far.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provide the reliable pulmonary carcinoma early diagnosis of a kind of stable operation disposable sterilized puncture needle.
This utility model solves the technical scheme that its technical problem adopts: the disposable sterilized puncture needle of a kind of pulmonary carcinoma early diagnosis, there is fixed block and be arranged on the medical silica-gel layer of fixed block bottom, be embedded in circular arc bend pipe at described fixed block, one end of described circular arc bend pipe is towards the bottom of fixed block, the other end is concordant with an end face of fixed block, joint in the bottom of described circular arc bend pipe and fixed block is provided with positive stop, in described circular arc bend pipe, being provided with thorn threads a needle, the middle part of threading a needle in described thorn is fixed with piston head, and described piston head and circular arc bend pipe are slidably connected, described thorn is threaded a needle and is stretched out in the outside of medical silica-gel layer along direction of extension one end of circular arc bend pipe, the other end stretches out in end face outside of fixed block and is provided with and grips handle, between the upper surface of described fixed block and circular arc bend pipe, be provided with venthole, be provided with and press groove at the middle part of the upper surface of described fixed block.
Further, as a kind of concrete embodiment, this utility model is provided with sealing rubber pad between described venthole and the upper surface of fixed block.
Further, as a kind of concrete embodiment, positive stop described in this utility model is bolted on the bottom of fixed block.
The beneficial effects of the utility model are: this utility model is simple in structure, reasonable in design, in operation, find point of penetration accurately, pin and press groove with the thumb of a hands, then another hands makes thorn thread a needle and pierce through action by gripping handle, solid and reliable, air-flow between air gap is discharged by venthole simultaneously, simply efficient.
Brief description of the drawings
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. fixed block, 2. circular arc bend pipe, 3. positive stop, 4. medical silica-gel layer, 5. thorn is threaded a needle, and 6. piston head, 7. grips handle, and 8. venthole is 9. pressed groove, 10. sealing rubber pad, 11. bolts.
Detailed description of the invention
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with this utility model.
The preferred embodiment of the disposable sterilized puncture needle of this utility model pulmonary carcinoma early diagnosis as shown in Figure 1, there is fixed block 1 and be arranged on the medical silica-gel layer 4 of fixed block 1 bottom, be embedded in circular arc bend pipe 2 at described fixed block 1, one end of described circular arc bend pipe 2 is towards the bottom of fixed block 1, the other end is concordant with an end face of fixed block 1, be provided with positive stop 3 at described circular arc bend pipe 2 and the joint of the bottom of fixed block 1, in described circular arc bend pipe 2, be provided with thorn and thread a needle 5, be fixed with piston head 6 at thread a needle 5 middle part of described thorn, and described piston head 6 is slidably connected with circular arc bend pipe 2, described thorn 5 outsides that stretch out in medical silica-gel layer 4 along direction of extension one end of circular arc bend pipe 2 of threading a needle, the other end stretches out in end face outside of fixed block 1 and is provided with and grips handle 7, upper surface and asking of circular arc bend pipe 2 at described fixed block 1 are provided with venthole 8, be provided with and press groove 9 at the middle part of the upper surface of described fixed block 1.
