Description
Technical field
The utility model belongs to the field of medical instrument technology, refers in particular to a kind of needle.
Background technology
In modern medicine, carrying out needing to use needle during suture operation, common needle is made of needle body and needle point,
Totally enclosed pin hole is equipped in the afterbody of needle body, which needs to thread in suture operation, but threading is difficult, time-consuming, can increase
Add the labor intensity of surgical work personnel, be unfavorable for the quick progress of operation.Authorization Notice No. is the China of CN204016383U
Utility model discloses a kind of needle, and including needle tip, the needle body and Aculeata, thread-laying device is equipped in Aculeata, the needle body and
Aculeata is arc-shaped, and thread-laying device opening is fitted closely in needle side, opening both sides, in the end of opening spaced inwardly.
Although this kind of needle facilitates threading, but due to suture in pin hole without fixation, in suture, suture is located at pin
One end in hole may be due to relaxation beyond wound position or one end for being located in pin hole of suture twist into knot and cause
Needle, which can not be successfully, to be pierced by, and the above situation gently then influences operation progress, is more likely to that suture is caused to fail when serious.
Utility model content
The purpose of this utility model is to provide a kind of needle, can with Quick-threading, while suture in pin hole one
End will not knot, and will not be wrapped in suture site or other positions.
What the purpose of this utility model was realized in:
A kind of needle, including needle point, the needle body, backshank and pin hole, the one side of pin hole is arranged with a pair of of hanging wire portion, hangs
Line portion, which is located inside and outside pin hole, has gap structure, and the centre in hanging wire portion, which is equipped with, to be contradicted position and contradict setting, and backshank is set
There is card slot, card slot bottom is equipped with the bayonet through backshank, and bayonet lock is equipped in bayonet, and the top of bayonet lock is equipped with upper card cap, upper card cap
Bigger than card slot, the bottom of bayonet lock is equipped with lower card cap, and lower card cap is bigger than bayonet, and bayonet lock can be along the depth direction activity of card slot.
The diameter of the bayonet lock be equal to bayonet diameter, 1.1~1.2 times of a diameter of bayonet lock diameter of card slot.
The depth of the card slot is the 20%~25% of bayonet depth.
The total length of the bayonet lock, upper card cap and lower card cap is 1.05~1.15 times of the total depth of card slot and bayonet.
The inner surface of the bayonet lock surface and card slot is equipped with anti-skid chequer.
The conflict position in the hanging wire portion is flat construction.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that:
1st, the pin hole of the utility model is arranged to the hanging wire portion with opening form, so as to which fast and easy threads;It meanwhile will
Hanging wire portion is arranged on the side of pin hole, and hanging wire portion is prevented to be arranged at backshank and be damaged to other positions during the withdraw of the needle;Pin
The effect of bayonet lock at tail is to tighten the suture pierced into pin hole, and is wrapped on bayonet lock, is fixed in card slot, thus
Suture just will not become slack the rough sledding such as generation knotting, winding in pin hole.The needle of such structure can be accelerated to wear
Linear velocity reduces and the rough sledding such as suture winding, knotting occurs in sewing process, so as to which the speed of operation stitching be effectively ensured
And effect.
2nd, the bayonet lock of the utility model and bayonet be arranged to thickness, avoid causing card since bayonet bore is excessive
Pin rocks in bayonet, suture is caused to fix insecure situation.
3rd, the diameter of the card slot of the utility model is more than the diameter of bayonet, if the depth of card slot is excessive, suture can not
Card slot is filled into consolidation, suture is still likely to depart from out of card slot at this time, will influence fixation of the bayonet lock to suture
Effect, the depth of card slot are much smaller than the depth of bayonet, and only need to suture be wound a bit of length on bayonet lock can be by card slot
It fills up, so as to have reliable compacting, anti-detachment effect to suture.
4th, the upper card cap of the utility model and lower card cap can only be higher by the small height in backshank both sides, in case upper card cap is under
Card cap excessively protrudes and is damaged to wound or other positions.
5th, the bayonet lock of the utility model and the surface of card slot all set anti-skid chequer, with increase bayonet lock, card slot and suture it
Between frictional resistance, so as to further reduce suture depart from card slot possibility.
6th, the conflict position in the hanging wire portion of the utility model is arranged to straight structure, can increase suture out of pin hole
The difficulty of disengaging, suture to out, then needed out of pin hole by contact site area greatly increase, therefore difficulty is just
Increase.

Specific embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-3:
A kind of needle, including needle point 1, the needle body 2, backshank 3 and pin hole 4, the needle body 2 is arcuate structure.
The one side of pin hole 4 is arranged with a pair of of hanging wire portion 5, and hanging wire portion 5, which is located inside and outside pin hole 4, has gap 6
Structure, the centre in two hanging wire portions 5, which is equipped with, to be contradicted position 501 and contradicts setting, and the conflict position 501 is flat construction.
Backshank 3 is equipped with card slot 7, and 7 bottom of card slot is equipped with the bayonet 8 through backshank 3, bayonet lock 9,9 table of bayonet lock are equipped in bayonet 8
The inner surface of face and card slot 7 is equipped with anti-skid chequer.
The diameter of bayonet lock 9 be equal to bayonet 8 diameter, 1.1 times of 9 diameter of a diameter of bayonet lock of card slot 7.The depth of card slot 7
For the 20% of 8 depth of bayonet.The top of bayonet lock 9 is equipped with upper card cap 901, and upper card cap 901 is bigger than card slot 7, and the bottom of bayonet lock 9 is equipped with
Lower card cap 902, lower card cap 902 is bigger than bayonet 8, and bayonet lock 9 can be along the depth direction activity of card slot 7.Bayonet lock 9, upper 901 and of card cap
The total length of lower card cap 902 is 1.1 times of the total depth of card slot 7 and bayonet 8.
When needle threads, operation suture thread is tensioned with finger first, then the gap 6 from 4 outside of pin hole is exerted oneself
The conflict position 501 in hanging wire portion 5 is caught in, suture comes out through contradicting the gap 6 of position 501 from 4 inside of pin hole;It then will suture
One end of line is transferred at backshank 3 and stretches, and on the other hand by card cap 902 of staying, makes outside 901 protruding card slot 7 of card cap, by suture
