In in outer needle 1, the crochet hook 4 is the open configuration being inclined outwardly, and three crochet hooks 4 extend out to form handgrip shape, relative to bipod hook
Needle grip is more uniform and secured, and crochet hook 4 is elastic material, and crochet hook 4 is gathered when retracting in outer needle 1, suture is firmly grasped, described
Ejection portion is located in outer tube 2, and the ejection portion is matched with stretching control unit stretches crochet hook 4 from the opening of outer 1 outer end of needle
Out.
The ejection portion includes the spring 5 for launching pipe 3 and being sleeved on 3 outside of ejection pipe, and the ejection pipe 3 is coaxially mounted to
In outer tube 2, the inner end of the ejection pipe 3 is connected with crochet hook 4, and the ejection pipe 3 in axial direction moves in outer tube 2,
Described 5 one end of spring is limited on 2 inner wall of outer tube, and the other end of the spring 5 is defined in the convex of prominent ejection pipe 3 setting
At edge, ejection pipe 3 is outer under the drive for stretching out control unit to be moved, and pushes crochet hook 4 to lean out outer needle 1, spring 5 compresses at this time, catches on line
Afterwards, it unclamps and stretches out control unit under the elastic force effect of spring 5, ejection pipe 3 drives crochet hook 4 to retract in outer needle 1, at this point, suture
It is trapped in inside outer needle 1, consequently facilitating suture pulls out.The stretching control unit includes contradicting to be connected to ejection 3 outer end of pipe
It middle shaft 6 and being connected in the pressing axis 7 of middle 6 outer end of shaft, the pressing axis 7 is set in the walking chamber in outer tube 2,
Pressing axis 7 is in axial direction advanced in outer tube 2, and the outer end of the pressing axis 7 extends to 2 outside of outer tube, the housing
The inner wall of pipe 2 is equipped with middle 6 rotary driving part of shaft, and the rotary driving part is bonded with middle shaft 6 and sets around middle shaft 6
It sets, middle 6 outer wall of shaft is equipped with the registration arm 8 along the protrusion setting of its axis, and the registration arm 8 is along middle 6 axis side of shaft
To setting, middle shaft 6 is extended in the end of registration arm 8 towards the pressing axis 7, and extends 8 end of registration arm of middle shaft 6
In rotary driving part, by the interaction of rotary driving part and registration arm 8, change registration arm 8 in rotary driving part
Position, thus position of the shaft 6 on 2 inner axis direction of outer tube in control, middle shaft 6 driving ejection pipe 3 and with ejection
The connected crochet hook 4 of pipe 3, makes crochet hook 4 lean out or retract.

At 10, the oblique side wall of 8 end of registration arm is stuck in serrated slot 10, and since serrated slot 10 is close to middle shaft 6, registration arm 8 is driven
The middle pressing of shaft 6 ejection pipe 3, spring-compressed repeat above-mentioned crochet hook 4 and lean out process, press pressing axis 7, middle 6 court of shaft again
Mobile to ejection pipe 3, the oblique side wall ends of registration arm 8 leave serrated slot 10, and into groove 9, middle shaft 6 is no longer pressed at this time
Pressure ejection pipe 3, under the action of spring 5, ejection pipe 3 drives crochet hook 4 to retract in outer needle 1, and line movement is grabbed in completion.
It is equipped with scale along axis on the outer wall of the pressing axis 7 and outer needle 1, so that the diameter to collar extension in hernical sac carries out
Measurement, former inventor substantially estimate when orifice sizes in surveying, if hernia needle tip is with a scale, that can be more
Collar extension diameter in accurately measuring, but inventor is in practice, it has been found that with a scale at hernia needle tip merely, in operation
Be inconvenient to read, therefore set scale in pressing axis 7, the built-in length of hernia needle point is read by the scale, to realize to hernia
The rough measure of intracapsular collar extension diameter.It is worth noting that, in hernical sac collar extension diameter and be not necessarily to precise measurement, using outer tube,
Scale in pressing axis 7, general comparison go out a discreet value.The inner end end wall of the middle shaft 6 is equipped with for inserting
Enter to launch the inserting groove of pipe 3.
Raised line 11, the raised line 11 and the outer tube at 7 inserting of pressing axis are set along its axis on 7 outer wall of pressing axis
Walking trough on 2 inner walls matches, the track route of the raised line 11 and walking trough cooperation restriction pressing axis 7.
