Abstract
The utility model relates to a skin suturing device capable of changing a needle, which belongs to the field of medical equipment. The utility model is composed of two large parts of a suturing gun which can be repeatedly used and a replaceable suturing needle box. The suturing gun and the suturing needle box are connected by a bayonet. The suturing needle box of the utility model can rotate the suturing gun in any angle with convenient operation and low cost.
Description
This utility model belongs to medical instruments field, further relates to a kind of Skin sewing needle of interchangeable pin.
Present disposable Skin sewing needle, its all parts are the material that disposable use consumes, and it is big therefore to make the mould amount, and waste of material is many, and apparatus volume is big, makes manufacturing, sterilization, packing, stock, transportation and all higher to use cost.And with in actual the use; each part that consumes only is suture needle and adnexa thereof; it is sutured portion; all helpful to resource and environmental conservation; the sutured portion of existing product and handle weldering simultaneously is one; it uses the bad adaptability of size to suture direction, and inconvenience changes sews up angle, makes to carry and use occasion is restricted.
The purpose of this utility model is to overcome the defective of above prior art, aims to provide a kind of Skin sewing needle of interchangeable pin.
This utility model is made up of reusable suture gun and removable box of suture needles two large divisions.Suture gun is connected by bayonet socket with box of suture needles.
Below in conjunction with accompanying drawing this utility model is described further.
Accompanying drawing 1 is this utility model overall structure figure.
Accompanying drawing 2 is this utility model box of suture needles structure chart.
Accompanying drawing 3 is this utility model suture gun structure chart.
Accompanying drawing 4 is this utility model box of suture needles head construction figure.
As accompanying drawing 3, the suture gun nock is provided with breech lock 13, button 15 and reed 16, the muzzle place is fan-shaped, when carrying out skin closure, when maybe needing to change box of suture needles, box of suture needles can be inserted muzzle, press the button 15, breech lock 13 is lifted, after box of suture needles is all pushed, put down button 15, reed 16 automatically resets button 15, installs promptly to accuse and finishes.
The suture gun rear portion is provided with handle, and anteriomedial is provided with slide block 17, is fixed with return spring 14 on the slide block 17, during stitching, handle 20 is pulled backward; Overcome the resistance of return spring 14, it is travelled forward slide block 17, thereby promote the push rod 8 of box of suture needles.When push rod 8 is finished whole stroke, promptly finish the skin closure process one time.
In sewing process, slide block 17 rear upper end are provided with the zigzag limited bayonet, be complementary with the latch of deck 18 above the slide block 17, deck top is provided with stage clip 19, when handle 20 pressurizations, the forming process classification action of suture needle 2, stage clip 19 makes deck 18 stressed, thereby the bayonet socket of slide block 17 is coincide, guarantee the irreversibility and the stability of the process of stitching.Finish when once sewing up, when being the complete molding of suture needle, deck 18 is pushed groove in the rifle shell 12 by handle 20, slide block 17 is retreated become possibility, when release handle 20, make slide block 17 promote the front end of deck 18 by return spring 14 effects, it is withdrawed from the groove of rifle shell 12, return to original readiness for operation.
Box of suture needles is closely cooperated by the last box for needle or pin 1 of injection mo(u)lding and following box for needle or pin 11 and forms, in the cavity of last box for needle or pin 1 and following box for needle or pin 11, the suture needle 2 that skin closure is used is housed successively, the piece 3 of pushing pin, the spring 4 of pushing pin, needle pushing plate 5, pressing spring 6, eedle presser 7, box of suture needles front port place is provided with guide board 9 and back stop 10, the box of suture needles rear portion is provided with push rod 8, suture needle 2 top depression.
When push rod 8 is sewn the rifle propelling, the eedle presser 7 driving pressure needle springs 6 and the spring 4 of pushing pin are pushed ahead suture needle 2 thereby promote needle pushing plate 5, and suture needle 2 overcomes back stop 10 resistances, and in the gap of last box for needle or pin 1 and following box for needle or pin 11, change direction, be pushed out the box of suture needles front port along the plane of guide board 9.After needle pushing plate 5 compression set suture needles 2, the resistance that eedle presser 7 overcomes pressing spring 6 continues forward, makes suture needle 2 brake formings, becomes the square type by original π type, and by back stop 10 suture needle 2 of molding is ejected.
After push rod 8 is sewn rifle and discharges, the spring 5 and 6 resiliences of pressing spring drive eedle presser 7 respectively and needle pushing plate 5 returns to original state of pushing pin.
Every pressure is once finished an above-mentioned sewing process.
If patient's stitching amount is bigger, can under the not enough situation of suture needle 2, change next box of suture needles, also the box of suture needles that can more renew for second patient.
Because expendable article of the present invention only are box of suture needles, therefore, use cost is significantly less than traditional disposable skin stapler.
Simultaneously, box of suture needles is that bayonet socket is connected with suture gun, so box of suture needles can be done arbitrarily angled rotation to being applied to suture gun, need not change work angle to the stitching of different angles, only needs that box of suture needles is done rotation and regulates, and use very convenient.
