Medical suture needle be sharp needle body including the axis, needle body's both ends are conical needle point portion, every respectively the inside adjacent continuous draw -in groove portion that has connect of needle point portion, the external diameter of draw -in groove portion is less than the maximum outer diameter of the cone of needle point portion, two be formed with the main part that supplies the stylolite to pass between the draw -in groove portion, the external diameter of main part is not less than the external diameter of draw -in groove portion, be provided with the through wires hole on the main part. The utility model has the advantages of reasonable design, can cooperate the automatic suturing machine tool to realize automatic sewing up, can dismantle used repeatedly, need disinfection and isolation's position to expose the washing in ensureing to use.
Description
Technical field
The utility model relates to medical suturing skill field, is specifically related to a kind of medical stitching of double end that is applied to automatic sewing apparatusPin.
Background technology
Medical suture needle is mainly used in surgical operation suturing, mostly is stainless steel wire and makes in backshank boring or fluting, and appearance is through polishing,Electrolytic treatments, very smooth; Pin type is divided into according to actual needs: round needle, angular pin, shovel pin, arc pin, staight needle etc.
Existing circle curved suture needle on market, is disposable use, can not carry out automatic sewing, in clinical practice, can not repeatSterilization uses, and therefore, needs further improvement.
Utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of reasonable in design, can coordinate automaticallySuture instruments is realized automatic sewing, can dismantle and reuse, and can guarantee needs the position of sterilization to expose clearly in applicationThe medical suture needle of washing.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme:
Medical suture needle, comprises that axis is the pin body of straight line, and the two ends of described pin body are respectively conical needle tip, everyThe inside adjacent continued access of individual described needle tip has draw-in groove portion, and the external diameter of described draw-in groove portion is less than outside the maximum of cone of described needle tipFootpath; Between two described draw-in groove portions, be formed with the main part passing for suture, the external diameter of described main part is not less than described draw-in grooveThe external diameter of portion, is provided with through wires hole on described main part.
As preferably, between described needle tip and described draw-in groove portion, be formed with transition Access Division, the external diameter of described transition Access Division withThe maximum outside diameter of the cone of described needle tip equates.
As preferably, the external diameter of described main part equates with the external diameter of described transition Access Division.
As preferably, described through wires hole connects and arranges along the radial direction of described main part, and is arranged at the centre of described main partPosition.
This medical suture needle, has at least following beneficial effect: can coordinate with automatic sewing apparatus real by the needle tip at two endsThe automatic sewing of existing bio-tissue, can be easily and removably clamping of suture instruments by draw-in groove portion, thereby carry out thoroughlyCleaning, sterilization, reach reusable condition, can effectively reduce clinical use cost, its reasonable in design,Easy to use.

Detailed description of the invention
Below in conjunction with drawings and Examples, further set forth the utility model. In the following detailed description, only by explanationMode has been described some example embodiment of the present utility model. Undoubtedly, those of ordinary skill in the art can recognize,In the situation that not departing from spirit and scope of the present utility model, can carry out described embodiment by various modeRevise. Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
As shown in Figures 1 to 4, medical suture needle, its entirety adopts linearity design, comprises that axis is the pin body 1 of straight line,The two ends of described pin body 1 are respectively conical needle tip 11, and the inside adjacent continued access of each described needle tip 11 has draw-in groove portion12, the outer diameter D 1 of described draw-in groove portion 12 is less than the maximum outside diameter D2 of the cone of described needle tip 11; Two described draw-in groove portionsBetween 12, be formed with the main part 13 passing for suture 2, the outer diameter D 3 of described main part 13 is not less than described draw-in groove portion 12Outer diameter D 1, on described main part 13, be provided with through wires hole 14.
With reference to figure 1, Fig. 3, in order to make sewing needle and suture instruments clamping convenient, and improve job stability, preferably adopted asLower structure: be formed with transition Access Division 15, described transition Access Division 15 between described needle tip 11 and described draw-in groove portion 12Outer diameter D 4 equate with the maximum outside diameter D2 of the cone of described needle tip 11.
In addition, the outer diameter D 3 of described main part 13 preferably equates with the outer diameter D 4 of described transition Access Division 15, so,Add and can improve ease of processing man-hour at needle body, practicality is good.
In the present embodiment, described through wires hole 14 connects and arranges along the radial direction of described main part 13, is preferably arranged at described masterThe middle part of body 13, is convenient to suture stress balance, is certainly not limited to this position, also can be arranged at described main bodyThe position, both sides of portion 13, no longer repeats.
Referring again to Fig. 1 to Fig. 3, this sewing needle can be coordinated with automatic sewing apparatus 3 and be realized biology by the needle tip 11 at two endsThe automatic sewing of soma, can be easily and removably clamping of suture instruments 3 by draw-in groove portion 12, needs to clean, sterilizationWhen sterilizing, thus sewing needle can be disassembled thoroughly clean, sterilization, reach reusable condition, energyThe clinical use cost of enough effectively reductions.
The foregoing is only the schematic detailed description of the invention of the utility model, not in order to limit scope of the present utility model. AppointWhat those skilled in the art, is not departing from equivalent variations and the amendment under the prerequisite of design of the present utility model and principle, done,All should belong to the scope of the utility model protection.
