Detailed description of the invention
As shown in Figure 1: a kind of medical hook line pin that can turn, comprises hollow core conductor pin 1, the anti-knee 4 of hollow core conductor pin and stitching thread guiding crochet hook 3; Described hollow core conductor pin 1 comprises handgrip 5 and needle tubing 6, and the lower end of needle tubing 6 is fixed on one end of handgrip 5, and needle tubing 6 is hollow, the upper and lower equal blow-by in two ends; On handgrip 5, be also provided with a ratchet 7; On ratchet 7, be wound with the bending lead-in wire 2 of controlling of line needle, its one end is fixed on ratchet 7, and the other end is fixed on needle tubing 6 tops; Described guiding bearded needle 3 one end comprise through wires hole 8.
Described needle tubing 6 is away from a side of handgrip 5, and top is provided with several positive triangular cuts 9 from top to bottom, and positive triangular cut 9 belows are provided with an interstitial hole 10; Described needle tubing 6 is near handgrip 5 one sides, and bottom is provided with several anti-triangular cuts 11 from bottom to top.Described anti-triangular cut 11 is all positioned at the below of interstitial hole 10, with the position non-overlapping of interstitial hole 10.
Described interstitial hole 10 is Long Circle breach, and when after the whole closures of positive triangular cut 9 on hollow core conductor pin needle tubing 6, the syringe needle of hollow core conductor pin 1 is just in time aimed at interstitial hole 10, is closed into the almost shape of sealing.
Described positive triangular cut 9 is isosceles triangle, and quantity is 6-12, and angle is 15-45 degree, and the angle sum of these breach is at 210-250 degree.Described anti-triangular cut 11 is isosceles triangle, and quantity is 2-3, and angle is 25-35 degree, and the angle sum of these breach is 25-35 degree.When after whole triangular cut closures on hollow core conductor pin 1, hollow core conductor pin will present water-drop-shaped.
The bending distal-most end of controlling lead-in wire 2 and needle tubing 6 of line needle, the outside left of breach is welded and fixed, and the bending lead-in wire 2 of controlling of line needle, through after the handgrip 5 of hollow core conductor pin 1, is fixed on ratchet 7, and ratchet 7 is with bilaterally adjustable check function.
Described needle tubing 6 and stitching thread guiding crochet hook 3 can bending, and the anti-knee 4 of hollow core conductor pin can not bending.The material of described needle tubing 6 is medical stainless steel or titanium alloy.
When this utility model uses, can be closed under the bending traction of controlling lead-in wire 2 of line needle that is subject to being fixed on needle tubing 6 far-ends away from several the positive triangular cuts 9 on the needle tubing 6 of handgrip 5 one end, make hollow core conductor pin 1 produce bending in positive triangular cut 9 closed location, when adjacent multiple positive triangular cut 9 is one by one after closure, the far-end of needle tubing 6, by engaging with interstitial hole 10 positions at needle tubing 6 middle parts, forms a closed-loop path.When needle tubing 6 bends to behind closed-loop path, just can utilize stitching thread guiding crochet hook 3, insert from the bottom inlet of handgrip 5 one end of needle tubing 6, along the cavity of needle tubing 6 inside, through the tendon that needs to sew up, then wear the arrival end of getting back to needle tubing 6 from closed-loop path combined mouth, finally, on stitching thread guiding crochet hook 3, after stitching thread, just can withdraw stitching thread guiding crochet hook 3, until complete sutural passing through.
In the time that the anti-knee 4 of hollow core conductor pin resides in the cavity in hollow core conductor pin 1, can guarantee that hollow core conductor pin 1 keeps linear state, being convenient to hollow core conductor pin 1 can successfully be punctured near the tendon that needs to sew up, then withdraw at leisure the anti-knee 4 of hollow core conductor pin, utilize the ratchet 7 on hollow core conductor pin 1 handgrip 5, the progressively bending lead-in wire 2 of controlling of stringing lead pin, makes hollow core conductor pin 1 bending rear through TFCC breach, finally forms closed wire guide needle.
The diameter of the anti-knee 4 of hollow core conductor pin is slightly less than the cavity diameter of hollow core conductor pin 1 inside, and in the time that the anti-knee 4 of hollow core conductor pin resides in the cavity of hollow core conductor pin 1 inside, the bending lead-in wire 2 of controlling of line needle can normally use.
