Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solution of the present invention.Following embodiment is only used for Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention It encloses.
As shown in Figure 1-Figure 3, a kind of hernia minimal invasive operation needle, including outer needle 1, outer tube 2, inner core and inner core control Component, the outer needle 1 are cored steel tubulose, and the outer tube 2 is medical silica-gel material, and medical silica-gel material is with the following method It is prepared: taking 39ml silica gel, 0.31ml silane coupling agent and 0.3ml silver base inorganic antibacterial agent, sequentially import three mouthfuls of 100ml It in bottle, and is heated in 57 DEG C of electric-heated thermostatic water bath, while carrying out 120 revs/min of stirring clockwise, continued anti- It answers 4 hours, then pours into obtained lotion in mold, be shaped to outer tube 2.The inner cavity of outer tube 2 is connected with outer 1 inner cavity of needle Logical, outer needle 1 is connected to 2 front end of outer tube, and the front end of the outer needle 1 and the rear end of outer tube 2 are open shape, and the inner core is worn Enter in outer needle 1 and outer tube 2, the inner core includes the crochet hook portion of front end, the ejection portion for being connected to crochet hook portion rear end and is connected to The stretching control unit of ejection portion rear end, by forming around the three foot crochet hooks 4 for forming handgrip, the crochet hook 4 is located in the crochet hook portion 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 crochet hook 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, the bullet It penetrates portion to be located in outer tube 2, the ejection portion is matched with stretching control unit stretches out crochet hook 4 from the opening of outer 1 outer end of needle.
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 flange that prominent ejection pipe 3 is arranged Place, ejection pipe 3 is outer under the drive for stretching out control unit to be moved, and crochet hook 4 is pushed to lean out outer needle 1, and spring 5 compresses at this time, after catching on line, 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 is detained Inside outer needle 1, consequently facilitating suture pulls out.The control unit that stretches out includes contradicting the transfer for being connected to ejection 3 outer end of pipe It axis 6 and is 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 outer tube 2 Inner wall is equipped with middle 6 rotary driving part of shaft, and the rotary driving part is bonded with middle shaft 6 and is arranged around middle shaft 6, described 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 arranged along middle 6 axis direction of shaft, Middle shaft 6 is extended in the end of registration arm 8 towards the pressing axis 7, and 8 end of registration arm for extending middle shaft 6 is set to rotation Turn in driving portion, by the interaction of rotary driving part and registration arm 8, change position of the registration arm 8 in rotary driving part, To position of the shaft 6 on 2 inner axis direction of outer tube in control, the middle driving of shaft 6 launches pipe 3 and is connected with ejection pipe 3 Crochet hook 4, so that crochet hook 4 is leant out or is retracted.
The rotary driving part protrudes from the inner wall setting of outer tube 2, includes arriving registration arm 8 in the rotary driving part It is located at the serrated slot 10 of the second position up to the groove 9 and restriction registration arm 8 of first position, as shown in figure 3, the serrated slot 10 In rotary driving part close to one end of middle shaft 6, the groove 9 extends along 2 axis direction of outer tube, and 9 depth of groove is greater than Serrated slot 10, the groove 9 and serrated slot 10 are depressed in rotary driving part setting, the bottom of groove 9 and serrated slot 10 and outer The inner wall of casing 2 is concordant, and the groove 9 extends along the axis direction of outer tube 2 and groove 9 is around multiple, the positioning of setting Arm 8 matches with groove 9.
Pressing axis 7 is pressed, shaft 6 is mobile towards ejection pipe 3 in drive, unclamps pressing axis 7, and registration arm 8 is located at serrated slot 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 direction of shaft again It is mobile to launch 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 Pipe 3 is launched, 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.
