Description

Percutaneous puncture catheter needle
Technical field
The utility model relates to catheter needle technical fields, specially percutaneous puncture catheter needle.
Background technique
Tumor patient chemically examine lesion sample when, need first to take lesion sample, Hospitals at Present, there is Very big defect, such as this patent: a kind of percutaneous transthoracic needle biopsy needle, application No. is 201810497392.5, the disadvantage is that because needle The internal diameter of pipe is planted oneself by needle core and is influenced, the lesion sample very little of interception, is chemically examined difficulty and is become larger, not easy to operate.
Utility model content
The purpose of this utility model is to provide percutaneous puncture catheter needles, to solve mentioned above in the background art ask Topic.
To achieve the above object, the utility model provides the following technical solutions: percutaneous puncture catheter needle, including needle tubing, institute The end integral type for stating needle tubing is provided with needle guard, and syringe needle is closely plugged in needle guard, and the end integral type of syringe needle is connected with needle core, Needle core is solid needle, and needle core is equipped with mark zone, and pushing block one is extended in the end of needle core, and integral type is provided with pushing block two, pushes away Block one is connected with handle away from one end integral type of pushing block two, and handle is socketed with rubber stopper, the needle away from one end of pushing block one Core is located in the inner cavity of needle tubing and handle, and needle core difference break-through rubber stopper and pushing block one, is fixedly connected on the needle core convex It rises, the inside of needle tubing is provided with groove.
Preferably, the one end of the needle guard far from needle tubing is in inclined plane shape identical with syringe needle shape, and two inclined plane shapes Port is parallel to each other.
Preferably, the cavity of the rubber stopper and needle tubing fits closely.
Preferably, the protrusion is located at rubber stopper close to the side of needle guard, and protrusion and groove shapes are mutually coincide.
Preferably, the needle guard diameter of bore is equal to needle core race diameter.
Preferably, the length of the needle core is equal to the sum of needle guard and the length of handle.
Compared with prior art, the utility model has the beneficial effects that
1, because needle guard diameter of bore is equal to needle core race diameter, so that needle guard and needle core can perfect fitting, Make the tissue other than lesion will not be cut in needle guard when catheter needle percutaneous puncture is to body foci in this way;
2, by the design of mark zone, when so that taking lesion sample, pushing block two being pulled to exit needle core, it can be seen that Label, the label can be red, play a warning role, can thus operator be avoided to be fully drawn out needle core;
3, solid needle is to when this catheter needle promotes human body, prevent needle guard 2 from having intercepted good tissue and enter it In, prevent operation error;
4, the sample that tumour is drawn in the way of syringe extraction negative pressure, can achieve the effect for reducing wound face, makes It is very small to obtain the pain that patient perceptions arrive, prevents patient's precipitate psychosocial due to pain from bearing;
5, interior empty and needle tubing the interior sky of needle guard, the sample size that negative pressure mode draws tumour is more, more convenient progress Chemical examination.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model;
Fig. 2 is structural schematic diagram at A in Fig. 1.
In figure: needle tubing 1, needle guard 2, syringe needle 3, rubber stopper 4, handle 5, pushing block 1, needle core 7, pushing block 28, mark zone 9 are convex 10 are played, groove 11.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model It clearly and completely retouches, it is clear that the embodiment retouched is only the utility model a part of the embodiment, instead of all the embodiments. Based on the embodiments of the present invention, what those of ordinary skill in the art obtained without making creative work has Other embodiments are fallen within the protection scope of the utility model.
Fig. 1 to Fig. 2 is please referred to, the utility model provides a kind of technical solution: percutaneous puncture catheter needle, including needle tubing 1, needle The end integral type of pipe 1 is provided with needle guard 2, and syringe needle 3 is closely plugged in needle guard 2, and the end integral type of syringe needle 3 is connected with needle core 7, needle core 7 is solid needle, and solid needle is to prevent needle guard 2 from having intercepted good tissue when this catheter needle promotes human body Into operation error wherein, is prevented, needle core 7 is equipped with mark zone 9, and pushing block 1 is extended in the end of needle core 7, and integral type is set It is equipped with pushing block 28, pushing block 1 is connected with handle 5 away from one end integral type of pushing block 28, and handle 5 deviates from one end of pushing block 1 It is socketed with rubber stopper 4, needle core 7 is located in the inner cavity of needle tubing 1 and handle 5, and needle core 7 distinguishes break-through rubber stopper 4 and pushing block 1, Protrusion 10 is fixedly connected on needle core 7, the inside of needle tubing 1 is provided with groove 11.
Further, the one end of needle guard 2 far from needle tubing 1 is in inclined plane shape identical with 3 shape of syringe needle, and two inclined plane shapes Port be parallel to each other.
Further, rubber stopper 4 and the cavity of needle tubing 1 fit closely.
Further, protrusion 10 is located at rubber stopper 4 close to the side of needle guard 2, and protrusion 10 and 11 shape of groove are mutual It coincide.
Further, 2 diameter of bore of needle guard is equal to 7 race diameter of needle core.
Further, the length of needle core 7 is equal to the sum of the length of needle guard 2 and handle 5.
Application method:
When needing to take lesion sample, first pushing block 28, so that rubber stopper 4 is moved to the left, as shown in Figure 1, to convex It plays 10 and is moved to and cooperate when be clamped with groove 11, stop pushing block 28, at this time the port phase of the inclined plane shape of needle guard 2 and syringe needle 3 Then mutually alignment is punctured to body foci by in-vitro percutaneous, it may be assumed that the needle guard 2 of 1 end of needle tubing is punctured to body foci, because It is equal to 7 race diameter of needle core for 2 diameter of bore of needle guard, and needle core 7 is solid needle, so that needle guard 2 and needle core 7 can be perfect Fitting, the tissue other than lesion will not be cut in needle guard 2 when catheter needle percutaneous puncture is to body foci in this way, prevent from grasping It makes mistakes, then pulls pushing block 1 to the right, tumour is drawn in the way of syringe extraction negative pressure in direction as shown in Figure 1 Sample can extract pushing block 28 out when encountering that need the tumor sample that extracts be not very much, when drawing to mark zone 9, stop Only pulling, syringe needle 3 has logged out in needle guard 2 at this time, and the end of needle guard 2 can play the role of the sample of auxiliary cutting tumour, It is exited in vivo when drawing the sample sufficient amount of tumour, and by needle guard 2, pushes pushing block 1, the sample of tumour in needle guard 2 is pushed away Out, it is chemically examined.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
