Abstract
The utility model discloses a needle threading device for surgical suture needles, belongs to the technical field of medical devices, and is used for carrying out rapid and convenient threading on surgical suture needles. The needle threading device disclosed by the utility model is characterized in that the front end of a handle is provided with a chuck and a lock sleeve; the front part of the chuck is provided with a lead-ring jack, the wall of a chuck body is provided with a plurality of elastic slots, the elastic slots are communicated with the lead-ring jack, and the outside surface of the chuck is provided with a screw thread; and the lock sleeve is sleeved on the chuck, and the inner wall of the lock sleeve is provided with a screw thread matched with the screw thread on the outside surface of the chuck. By using the needle threading device disclosed by the utility model, lead rings different in diameter can be replaced conveniently so as to adapt to needle holes different in size and satisfy surgical needs; the handle and the lead rings can be combined independently so as to facilitate disinfection and convenient replacement of the lead rings after being used wearily; the rhomboic lead ring can effectively prevent a suture needle from slipping off after passing through a needle hole, so that an operator can carry out threading on the suture needle more unhurriedly and conveniently without worrying about the occurrence of a situation that the suture needle slips off from the lead ring; and an threading action of the lead rings is performed quickly and conveniently, thereby greatly improving the threading speed and the operating efficiency. Meanwhile, the needle threading device is simple in structure and easy to use, and can adapt to the threading demands of various surgical suture needles.
Description
Technical field
This utility model relates to and a kind of operation sewing needle is carried out the down-lead device of threading, belongs to the medical device technical field.
Background technology
In carrying out medical operating, the stitching of wound one of the link that is absolutely necessary.Need stitching thread be penetrated in the pin hole of medical suture needle during stitching.Because the pin hole of medical suture needle is tiny, and sewing needle is curved again, manual threading is inconvenience very, and therefore medical needle threading device has obtained application.Use to find that through practice several kinds of medical needle threading devices that use at present all have some defectives, if any nail set adopt the acicular feed-through collar that inserts pin hole of hook to constitute with the shears that can reset, its shortcoming is that complex structure, volume are big, sterilization inconvenience; The nail set that also has adopts the steel wire feed-through collar, and it is simple in structure, easy to operate, but feed-through collar can not change, can not adapt to the needs of multiple pin hole, improved necessity is also arranged.
The utility model content
This utility model technical problem to be solved provide a kind of simple in structure, use and sterilize conveniently, feed-through collar can change, adapt to different pin holes and sutural operation sewing needle needle threading device fast.
The technical scheme that solves the problems of the technologies described above is:
A kind of operation sewing needle needle threading device, it is made up of feed-through collar, handle, and its improvements are; The front end of handle has chuck and lock sleeve, and the anterior leaded ring jack of chuck has a plurality of elastic grooves on the chuck body wall; The axially parallel of the direction of elastic groove and feed-through collar jack, elastic groove is connected with the feed-through collar jack, and the chuck outer surface has screw thread; Lock sleeve is sleeved on the chuck, and the lock sleeve inwall has screw thread and chuck outer surface thread to be complementary.
Above-mentioned operation sewing needle needle threading device, said chuck front end has chamfering, and the inwall near an end of feed-through collar of lock sleeve is taper, and the angle of the chamfering of chuck and the conical inboard wall of lock sleeve is complementary.
Above-mentioned operation sewing needle needle threading device, said elastic groove are 3-4, evenly are arranged on the chuck body wall.
Above-mentioned operation sewing needle needle threading device; Said feed-through collar be shaped as rhombus, constitute by the parallel steel wire in bending back, rhombohedral major axis is the axis of feed-through collar; The two ends of feed-through collar are inserted in the feed-through collar jack of collet front, and the feed-through collar steel wire diameter is 0.06-0.3mm.
The usefulness of this utility model is:
After adopting the structure of chuck and lock sleeve, can change the feed-through collar of different-diameter easily,, satisfy the demand of operation to adapt to the pin hole of different sizes; Handle and the combination of feed-through collar independence can be convenient in time be convenient for changing after sterilization and the feed-through collar use fatigue; Rhombohedral feed-through collar can prevent to skid off after sewing needle from penetrating pin hole effectively, makes operator's threading calm more, convenient, need not take the generation that sewing needle skids off from feed-through collar into account; The feed-through collar threading fast, has conveniently improved threading speed and work efficiency greatly.
This utility model is simple in structure, making is easy, easy to use, can adapt to the threading demand of multiple operation sewing needle, be worth of widely use.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the user mode figure of this utility model.
Labelling is following among the figure: feed-through collar 1, chuck 2, lock sleeve 3, feed-through collar jack 4, elastic groove 5, handle 6, jaw 7, sewing needle 8, stitching thread 9.
The specific embodiment
This utility model is made up of feed-through collar 1, chuck 2, lock sleeve 3, handle 6.
Show among the figure that chuck 2 and lock sleeve 3 are connected the front end of handle 6, chuck 2 outer surfaces have screw thread, and lock sleeve 3 inwalls have screw thread, and their screw thread is complementary, and lock sleeve 3 is screwed on the chuck 2.
Meanwhile, chuck 2 front ends have chamfering, and the inwall near an end of feed-through collar 1 of lock sleeve 3 is taper, and the angle of the conical inboard wall of the chamfering of chuck 2 and lock sleeve 3 is complementary.
Show among the figure; The anterior leaded ring jack 4 of chuck 2 has 3-4 elastic groove 5, the axially parallel of the direction of elastic groove 5 and feed-through collar jack 4 on chuck 2 body walls; Elastic groove 5 is connected with feed-through collar jack 4, and elastic groove 5 is slit into several jaws 7 with chuck 2 forward part.When lock sleeve 3 tightening chucks 2; The chamfering of chuck 2 front ends can move forward along the tapering point of lock sleeve 3 inwalls; To the centre extruding, owing to flexible groove 5 between the jaw 7, so jaw 7 can clamp feed-through collar 4 to the centre with jaw 7; This structure all has application in the various dops of mechanical industry, but in medical nail set, uses still initiative.
Show among the figure, said feed-through collar 1 be shaped as rhombus, constitute by the parallel steel wire in bending back, rhombohedral major axis is the axis of feed-through collar 1, the two ends of feed-through collar 1 are inserted in the chuck 2 forward feed-through collar jacks 4.Feed-through collar 1 steel wire diameter can be selected according to the aperture of pin hole, is slightly less than the width of pin hole, and steel wire diameter is 0.06-0.3mm.
This utility model in use, the feed-through collar 1 of selecting earlier the pin hole of steel wire diameter and sewing needle 8 to be complementary inserts the two ends of feed-through collar 1 in the feed-through collar jack 4 of chuck 2, the lock sleeve 3 of screwing makes the two ends clamping of jaw 7 with feed-through collar 1.Then feed-through collar 1 is penetrated from pin hole, penetrate into stitching thread 9 in the rhombus collar of feed-through collar 1.At last feed-through collar 1 is pulled out from the pin hole of sewing needle 8, feed-through collar 1 is about to stitching thread 9 and takes pin hole out of, accomplishes the threading process.
