Abstract
The utility model relates to a living body sampler, in particular to a needle-tube-type living body sampler for a tumour. The needle-tube-type living body sampler comprises a needle head and a piston rod and the needle head is provided with an inclined tip end. The needle-tube-type living body sampler is characterized in that an inclined cutting plate is hinged to the inner wall at the tip end of the needle head, the inclination direction and the inclination angle of the cutting plate are the same as the inclination direction and the inclination angle of the tip end, the movable end of the cutting plate is close to the vertex point of the tip end, a circle of blades are arranged on the inner side of the movable end of the cutting plate inwards and a plurality of liquid suction holes are formed in the tube wall of the needle head. A longitudinal through hole is formed in the piston rod, a pull rod is fixedly arranged on the inner wall of the cutting plate and the pull rod is connected with a transverse pull handle after stretching out from the longitudinal through hole. By means of the needle-tube-type living body sampler for the tumour, liquid samples can be sampled in a multi-point mode, solid tissue can also be sampled, and sampled samples are made to be representative.
Description
(1) technical field
This utility model relates to a kind of live body sampler, particularly needle tube type live body sampler for a kind of tumor.
(2) background technology
Tumor is one of instrument conventional to tumor living-body tissue sampling with needle tube type live body sampler, it is punctured into and in cerebroma, is drawn cerebroma biological tissue by syringe needle, but be only limited to local liquid, can not complete solid tissue's sampling, with regard to cerebroma generally speaking, liquid after sampling lacks representative, often affects the judgement to the state of an illness.
(3) summary of the invention
This utility model, in order to make up the defect of prior art, provides a kind of and can get solid, liquid brain tumor tissue, the representative tumor needle tube type live body sampler of institute's sample thief simultaneously.
This utility model is achieved by the following technical solution:
Needle tube type live body sampler for a kind of tumor, comprise syringe needle and piston rod, described syringe needle has the tip of inclination, it is characterized in that: the cutting plate that is hinged with inclination on the point inwall of described syringe needle, the direction that described cutting plate tilts is identical with incline direction and the angle at described tip with angle, the movable end of described cutting plate is by subapical summit and be inwardly provided with a circle blade in the inner side of the movable end of cutting plate, and the tube wall of described syringe needle is provided with some imbibing holes; Described piston rod is provided with longitudinal hole, on described cutting plate inwall, is installed with pull bar, and described pull bar is the horizontal pull handle of connection one from longitudinal hole stretches out.
The beneficial effects of the utility model are:
1,, owing to being provided with some imbibing holes on syringe needle tube wall, in the time of sampling, be just not limited to a some sampling, but multidraw has strengthened samples' representativeness.
2, owing to being provided with cutting plate on the most advanced and sophisticated inwall of syringe needle, in the time that solid tissue is thrust at the tip of medicated pillow, pull pull bar, the circle many solid tissues of blade that survey in cutting plate cut, and along with the movement of cutting plate, solid tissue is pushed in syringe needle, has so just obtained the sample of solid tissue.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 be in Fig. 1 A to partial elevation view;
Fig. 3 is the enlarged drawing at B place in Fig. 1.
In figure, 1 syringe needle, 2 piston rods, 3 tips, 4 cutting plates, 5 blades, 6 imbibing holes, 7 longitudinal holes, 8 pull bars, 9 horizontal pull handles.
(5) specific embodiment
Accompanying drawing is specific embodiment of the utility model.As Fig. 1, Fig. 2, shown in Fig. 3, this kind of needle tube type live body sampler for tumor, comprise syringe needle 1 and piston rod 2, syringe needle 1 has the tip 3 of inclination, on 3, the tip inwall of syringe needle 1, be hinged with the cutting plate 4 of inclination, cutting plate 4 ovalizes, the direction that cutting plate 4 tilts is identical with angle with described most advanced and sophisticated 3 incline direction with angle, and can with syringe needle 1 inwall closure, the stiff end of cutting plate 4 is away from the summit at tip 3, the movable end of cutting plate 4 is near the summit at tip 3, and be inwardly provided with a circle blade 5 in the inner side of the movable end of cutting plate 4, the tube wall of syringe needle 1 is provided with some imbibing holes 6, piston rod 2 is provided with longitudinal hole 7, on cutting plate 4 inwalls, is installed with pull bar 8, and pull bar 8 is the horizontal pull handle 9 of connection one from longitudinal hole 7 stretches out.
Work process is as follows: shift piston rod 2 onto the end, syringe needle 1 thrusts cerebroma inside, promotes horizontal pull handle 9, cutting plate 4 is separated with the inwall at the tip 3 of syringe needle 1, solid tissue is thrust in the tip of syringe needle 13, pull horizontal pull handle 9, laterally pull handle 9 pulls pull bar 8 to make cutting plate 4 and syringe needle 1 inwall closure, solid tissue is cut, pulls piston rod 2, and liquid tissue sucks in syringe needle 1 from imbibing hole 6, enter needle tubing, after washing, extract syringe needle 1, sampling work completes.
Except technical characterictic described in description, all the other technical characterictics are those skilled in the art's known technology.
