Abstract
The utility model discloses a novel puncture biopsy needle cylinder, belonging to the field of medical surgical instruments. The novel puncture biopsy needle cylinder comprises a needle cylinder, a needle nozzle and a push rod, wherein a sealing cavity is arranged between the needle nozzle and the needle cylinder; the needle nozzle is connected with the needle cylinder through a hole channel; the height of the sealing cavity is the same with the diameter of the needle cylinder; and the sealing cavity is filled with liquid. Compared with the prior art, the novel puncture biopsy needle cylinder has the characteristics of having convenient operation, effectively controlling needle insertion angle, enhancing puncture success rate, and the like.
Description
Technical field
This utility model relates to a kind of medical surgical instrument, especially a kind of novel aspiration biopsy syringe, and that this syringe has is easy to operate, time saving and energy saving, improve characteristics such as puncture success rate.
Background technology
The aspiration biopsy technology of suspicious lesions tissue is widely used clinical, and the most frequently used instrument is negative pressure suction type and spring biopsy needle; Its primary structure is made up of piercing needle and suction syringe or ejector two parts.Paracentesis depth is represented by the reference mark on the syringe needle, is estimated by rule of thumb by the operation doctor and needle angle is many, is easy to occur error in the piercing process, thereby causes puncture failure, causes certain misery to the patient.
The utility model content
Technical assignment of the present utility model is to provide a kind of novel aspiration biopsy syringe at above-mentioned deficiency of the prior art.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of novel aspiration biopsy syringe, comprise syringe, pin mouth and push rod, wherein, between pin mouth and syringe, be provided with annular seal space, pin mouth passing hole channel links to each other with syringe, the height of annular seal space is identical with the diameter of syringe, and liquid is housed in annular seal space.
Be provided with scale on the annular seal space surface, annular seal space central authorities are designated as 0 °, begin both sides from 0 ° of line and respectively are divided into nine sections, amount to 18 sections.
Annular seal space bottom circle centre position is designated as 90 °, begins both sides from 90 ° of lines and respectively is divided into nine sections, amounts to 18 sections.
Liquid is blue.
The beneficial effect that the utlity model has is:
1, simple in structure, easy to operate, the workload that alleviates the medical worker.
2, being convenient to the doctor holds needle angle effectively, improves puncture success rate.
Description of drawings

The sectional view of Fig. 2 this utility model annular seal space.
The ground plan of Fig. 3 this utility model annular seal space.
The specific embodiment
With reference to Figure of description this utility model is done following detailed description the in detail:
As shown in the figure, this utility model comprises syringe 1, pin mouth 2 and push rod 3, between pin mouth 2 and syringe 1, be provided with annular seal space 4, the depth of section of annular seal space 4 is identical with the diameter of syringe 1, pin mouth 2 links to each other with syringe 1 by the duct 5 of running through annular seal space 4, liquid 6 is housed in annular seal space 4, and liquid 6 is blue; Liquid 6 volumes account for half of annular seal space, a mark line is done in centre at annular seal space 4 sidewalls, is designated as 0 °, is baseline with this line then, respectively be divided into nine sections up and down, upper and lower each nine, totally ten eight, two ends all are labeled as 45 °, on the top and mark line bottom, get mid point and be decided to be 90 °, respectively be divided into nine sections to both sides equally then, totally ten eight sections.With 0 °/90 ° be baseline, on the mark line of both sides, be labeled as 5 °, 10 °, 15 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, 50 °, 55 °, 60 °, 65 °, 70 °, 75 °, 80 °, 85 °, 90 ° respectively.
When 1 vertical of syringe, the concordant 0 ° of line of liquid level; When syringe 1 inclination 45, because liquid should occupy annular seal space 4 half, 45 ° of mark line places of the concordant sidewall of liquid level.And the like: when syringe 1 inclination was arbitrarily angled, the colored liquid level in the annular seal space 4 is the respective markers line of corresponding sidewall just in time, has reduced error effectively, has improved puncture success rate.
