Abstract
The utility model discloses a kind of Novel puncture needle, comprise main puncture needle, be provided with main puncture nook closing member in described main puncture needle, described main puncture needle is combined with secondary puncture needle; Secondary puncture needle comprises end, needle tubing portion, elastic bending part and needle tip; After described secondary puncture needle coordinates with main puncture needle, the needle tip of secondary puncture needle and elastic bending part are positioned at outside the needle point of main puncture needle; Described elastic bending part is that elastomeric material or memory alloy material are made; Described secondary puncture needle is provided with secondary puncture nook closing member, owing to having adopted technique scheme, this utility model is in the time of puncture, if the puncture position of main puncture needle is inaccurate, but skew is little again, at this moment needs to enter from main puncture needle with secondary puncture needle, puncture in tram, this puncture mode, punctures after can avoiding main puncture needle to extract again, causes the injury again to puncture organ.Through clinical trial certificate, the number of times that greatly reduces puncture of the present utility model, is down to 10% by complication rate.
Description
Technical field
This utility model relates to medical instruments field, specifically, relates to a kind of Novel puncture needle.
Background technology
When tradition lancet puncture, often select puncture path with operator's experience, carry out blind wearing, needle angle is held inaccurate, error is larger, and puncture success rate is lower, generally need to repeatedly puncture, repeatedly CT scan, operation and lack of standardization, complication is more, and the radiation dose that patient accepts is larger.The puncture success rate of common puncture needle is generally in 60% left and right, and complication rate is in 70% left and right.
Utility model content
The technical problems to be solved in the utility model is to overcome above-mentioned defect, and a kind of Novel puncture needle that reduces puncture time and complication rate is provided.
For addressing the above problem, the technical scheme that this utility model adopts is:
A kind of Novel puncture needle, comprises main puncture needle, is provided with main puncture nook closing member in described main puncture needle, it is characterized in that: described main puncture needle is combined with secondary puncture needle;
Secondary puncture needle comprises end, needle tubing portion, elastic bending part and needle tip;
After described secondary puncture needle coordinates with main puncture needle, the needle tip of secondary puncture needle and elastic bending part are positioned at outside the needle point of main puncture needle;
Described secondary puncture needle is provided with secondary puncture nook closing member.
As a kind of prioritization scheme:
End, needle tubing portion, elastic bending part and the needle tip of described secondary puncture needle are structure as a whole.
As another kind of prioritization scheme:
The elastic bending part of described secondary puncture needle and needle tubing portion, needle tip are Split type structure.
Improve as one:
Described puncture apparatus also comprises carrying case, and described main puncture needle, main puncture nook closing member, secondary puncture needle and secondary puncture nook closing member are all positioned at carrying case.
Owing to having adopted technique scheme, this utility model is in the time of puncture, if the puncture position of main puncture needle is inaccurate, but be offset little again, at this moment needing to enter from main puncture needle with secondary puncture needle, punctures in tram, this puncture mode, after can avoiding main puncture needle to extract, puncture again, cause the injury again to puncture organ.Through clinical trial certificate, the number of times that greatly reduces puncture of the present utility model, is down to 10% by complication rate.
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of a kind of embodiment of a kind of Novel puncture needle of this utility model;
Accompanying drawing 2 is structural representations of carrying case in accompanying drawing 1;
In figure: the main puncture needle of 1-; The secondary puncture needle of 2-; The secondary puncture of 3-nook closing member; 4-end; 5-needle tubing portion; 6-elastic bending part; 7-needle tip; 8-carrying case; The main puncture nook closing member of 9-.
Detailed description of the invention
Embodiment 1: as depicted in figs. 1 and 2, a kind of Novel puncture needle, comprises main puncture needle 1, is provided with main puncture nook closing member 9 in described main puncture needle 1, and described main puncture needle 1 is combined with secondary puncture needle 2;
Secondary puncture needle 2 comprises end 4, needle tubing portion 5, elastic bending part 6 and needle tip 7;
After described secondary puncture needle 2 coordinates with main puncture needle 1, the needle tip 7 of secondary puncture needle 2 and elastic bending part 6 are positioned at outside the needle point of main puncture needle 1;
Described elastic bending part 6 is made for elastomeric material or memory alloy material; This material can change shape in the situation that having external force, recovers original form in the situation that there is no external force.
Described secondary puncture needle 2 is provided with secondary puncture nook closing member 3.
End 4, needle tubing portion 5, elastic bending part 6 and the needle tip 7 of described secondary puncture needle 2 are structure as a whole.
Described puncture apparatus also comprises carrying case 8, and described main puncture needle 1, main puncture nook closing member 9, secondary puncture needle 2 and secondary puncture nook closing member 3 are all positioned at carrying case 8.
In the time that needle tip 7 enters main piercing needle 1, angle disappears, when needle tip 7 from main piercing needle 1 out time angle recover again, like this on main puncture needle 1 puncture channel basis, just can change as required far-end puncture direction, realize and drawing materials away from main puncture channel, reduce main lancet puncture number of times, simultaneously revolute puncture needle 2, its needle tip 7 can stretch out and multiple different targets that puncture within the scope of 180 °, realizes multi-point sampling truly.
Embodiment 2: as depicted in figs. 1 and 2, a kind of Novel puncture needle, comprises main puncture needle 1, is provided with main puncture nook closing member 9 in described main puncture needle 1, and described main puncture needle 1 is combined with secondary puncture needle 2;
Secondary puncture needle 2 comprises end 4, needle tubing portion 5, elastic bending part 6 and needle tip 7;
After described secondary puncture needle 2 coordinates with main puncture needle 1, the needle tip 7 of secondary puncture needle 2 and elastic bending part 6 are positioned at outside the needle point of main puncture needle 1;
Described elastic bending part 6 is made for elastomeric material or memory alloy material; This material can change shape in the situation that having external force, recovers original form in the situation that there is no external force.
Described secondary puncture needle 2 is provided with secondary puncture nook closing member 3.
Described puncture apparatus also comprises carrying case 8, and described main puncture needle 1, main puncture nook closing member 9, secondary puncture needle 2 and secondary puncture nook closing member 3 are all positioned at carrying case 8, are easy to carry like this and preserve.
The difference of the present embodiment and embodiment 1 is: the elastic bending part 6 of described secondary puncture needle 2 is Split type structure with needle tubing portion 5, needle tip 7.
Equally, in the time that needle tip 7 enters main piercing needle 1, angle disappears, when needle tip 7 from main piercing needle 1 out time angle recover again, on main puncture needle 1 puncture channel basis, just can change as required far-end puncture direction like this, realize and drawing materials away from main puncture channel, reduce main lancet puncture number of times, revolute puncture needle 2 simultaneously, its needle tip 7 can stretch out and multiple different targets that puncture within the scope of 180 °, realizes multi-point sampling truly.
