Abstract
The invention provides a semi-automatic sewing needle holder belonging to a medical surgical instrument. The needle holder is provided with a female blade and a male blade, the front parts of which are articulated together; the front parts of the two blades are jaws, the rear parts are doubled as hand grips, and the middle parts of the two blades are respectively provided with tooth buckles capable of fixing the two blades together; the front end of the female blade is provided with a threading hole; the rear part of the male blade is provided with a coil; a gear and a rack are meshed on the coil; the front end of the rack is provided with a trigger; and a hook spring is arranged between the trigger and the male blade. The sewing needle holder changes the structure and the sewing and knot tying method of the traditional sewing needle holder and can flexibly pass threads, sew and tie knots in the surgery process so as to more safely, conveniently and simply to complete the surgery sewing process.
Description
Technical field
The present invention relates to a kind of medical surgical instrument, especially a kind of needle holder.
Background technology
From over more than 100 year of physianthropy surgery operating technology birth, the structure of operation sewing needle and sewing needle holder never changes.Existing sewing needle holder is by consisting of by the hinged handle of bearing pin, and the front portion of handle is that needle forceps mouth, rear portion have tooth to buckle.The convenience that this sewing needle holder uses is poor, and complicated operation during stitching moves loaded down with trivial detailsly, and motility is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of semi-automatic sewing needle holder, convenience and motility when sewing up to improve.
The present invention realizes like this, semi-automatic sewing needle holder, it has anterior hinged female leaf and male leaf, two leaves are anterior, and there is respectively the tooth button that two leaves can be fixed together at the middle part of two leaves for jaw, rear portion double as handle, and the front end of female leaf has through wires hole, the rear portion of male leaf is equipped with coil, have wheel and rack to mesh together on the coil, the front end of tooth bar has trigger, colludes spring between trigger and the male leaf.
This sewing needle holder has changed the structure of existing sewing needle holder and stitching, knotting method, can be in operation process, and motor-driven, pass line, stitching, knotting neatly, safer, more convenient, finish the operation stitching process more simply.
Description of drawings
Fig. 1 is the sketch map of sewing needle structure used among the present invention and the present invention.
Fig. 2 has represented the matching relationship of rack and pinion.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
As shown in drawings, the present invention's semi-automatic sewing needle holder, it has anterior hinged female leaf 1 and male leaf 2, two leaves are anterior, and there is respectively the tooth button 13 that two leaves can be fixed together at the middle part of two leaves for jaw, rear portion double as handle, and the front end of female leaf has through wires hole 6, the rear portion of male leaf is equipped with coil 4, have gear 18 and tooth bar 14 to mesh together on the coil, the front end of tooth bar has trigger 3, colludes spring 8 between trigger and the male leaf.
Ring is arranged 7 on described female leaf 1 rear portion.Hold the ring handle, be convenient to open tooth button 13, with the clip suture pin.Obviously, also can directly by pulling the handle at female leaf, male leaf rear portion, open the tooth button.
Suture 12 on the present invention's the semi-automatic sewing needle holder is drawn by coil 4, reaches the most advanced and sophisticated pin hole 11 of sewing needle through female leaf through wires hole 6.Collude plate machine 3, tooth bar 14 rotates by the gear driven coil on the coil, and the part suture can return to twine namely strains 1～10cm on the coil; During loosening plate machine, under the elastic force effect of colluding spring, trigger rebounds automatically, the coil backward rotation, and suture 12 gets loose from coil and namely realizes becoming flexible.
When the present invention's semi-automatic sewing needle holder is applied to suture tissue, open first the tooth button, make the jaw of female leaf, male leaf front end clamp sewing needle, connect stitching thread after, closed tooth button.After the sewing needle tip penetrates suture tissue and exposes suture the end of a thread, clamp suture with vascular forceps, sewing needle is return.Cooperates with vascular forceps or finger finish the knotting process after, collude the plate machine, make suture strain toe-in; The toe-in such as second, the 3rd is finished in the elongation that gets loose of loosening plate machine, suture again.After cutting off suture, can sew up next time, need not to repeat again threading.
The tooth button is made of the toothed bar of contact surface that protrudes on male leaf and the female leaf, and the tooth button of this structure is prior art, has just adopted this tooth button on the utensils such as existing medical needle holder.
The front end of male leaf also can have through wires hole.Can there be another through wires hole 15 at position at the close coil of male leaf, to play the guide function to suture.
Tooth bar can pass the handle at male leaf rear portion, to play the guide effect to the tooth bar motion.
Colluding spring can be made of two reeds that are plugged in together, and two reeds can be separately fixed on trigger and the male leaf.
As shown in Figure 2, coil is fixed in the rotating shaft 16, also is fixed with gear 18 in the rotating shaft, and shaft set is on pole 17, and pole is fixed on the male leaf.Obviously also can adopt tooth bar, the gear transmission structure of other structures, as long as the forward and backward moving rotating of tooth bar can be changed to the forward and reverse rotation of coil, be fixed on the coil such as direct geared, coil directly is sleeved on the male leaf.
During use, suture one end passes sewing needle, and the other end is wrapped on the coil.Suture adopts operation routine line.
Coil is installed in the middle part of the handle at male leaf rear portion, and therefore this handle can be bending.
The front portion of female leaf and male leaf can be hinged by hinge 5.
