Abstract
The utility model relates to the field of medical apparatuses and instruments, in particular to a novel tumor biopsy sampling device. The novel tumor biopsy sampling device comprises a syringe, a piston and a syringe needle, wherein the piston is arranged inside the syringe, a push rod is connected with the back end of the piston, the front end of the syringe is connected with a connector at the tail end of the syringe needle in a rotary mode, and two tooth blades are arranged in the interior of the front end of the syringe needle. The novel tumor biopsy sampling device is simple in structure. Through the tooth blades arranged at the front end of the syringe needle, enough tumor sample tissues can be cut, a success rate of biopsy sample negative-pressure extraction is improved, and the novel tumor biopsy sampling device is convenient to operate, time-saving, labor-saving and capable of lowering work difficult of medical staff.
Description
Technical field
This utility model relates to medical instruments field, especially a kind of novel tumor biopsy sampler.
Background technology
On clinical tumor, often need draw materials for patient carries out tumor biopsy, used utensil is ordinary syringe at present, after the syringe needle of syringe thrusts inside tumor, utilizes the principle of negative pressure sample drawn.Because the negative pressure value that forms in the syringe is lower, sample drawn is organized less, and success rate is lower, has increased great work difficulty to the medical worker.
The utility model content
The purpose of this utility model is to provide a kind of novel tumor biopsy sampler in order to overcome above-mentioned technical disadvantages.
The technical scheme that this utility model technical solution problem adopts is: a kind of novel tumor biopsy sampler, comprise syringe, piston and syringe needle, be provided with piston in the described syringe, piston rear end is connected with push rod, the adapter of described syringe front end and syringe needle end spins, and described syringe needle front end inside is provided with two lands.
The beneficial effect that this utility model has is: this utility model is simple in structure, and the land by arranging at the syringe needle front end can cut to enough tumor sample tissues, improved the success rate of biopsy sample negative pressure extracting, easy to operate, time saving and energy saving, reduced medical worker's work difficulty.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Do following detailed description below in conjunction with 1 pair of this utility model of accompanying drawing.
As shown in Figure 1, this utility model comprises syringe 1, piston 6 and syringe needle 3, is provided with piston 6 in the described syringe 1, and piston 6 rear ends are connected with push rod 2, and the adapter 5 of described syringe 1 front end and syringe needle 3 ends spins, and described syringe needle 3 front end inside are provided with two lands 4.In the use, land 4 cutting tumor tissues, piston 6 retreat to make under push rod 2 effects and form subnormal ambient in the syringe 1, and the tumor tissues under the cutting is drawn into syringe 1, thereby the syringe needle 3 of outwarding winding is released the sample tissue.
Claims (1)
1. novel tumor biopsy sampler, comprise syringe, piston and syringe needle, it is characterized in that: be provided with piston in the described syringe, piston rear end is connected with push rod, the adapter of described syringe front end and syringe needle end spins, and described syringe needle front end inside is provided with two lands.
