The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention and characteristics are elaborated.
As Fig. 1～shown in Figure 17, purse-string device for surgical department comprises shell 1 and handle 8, and shell 1 has two, and the middle part is pivotally connected by pin 2, forms the bascule that is similar to pliers.Handle 8 is positioned at shell 1 afterbody, and the head of every shell 1 is to sew up capitiform to become two stitching heads up and down, and two stitching heads cooperatively interact and play the effect of sewing up pocket up and down.Be provided with push pedal 12 and nail bin 3 in the inside of sewing up head, the inside of nail bin 3 is provided with pushing slice of nail 4 and nail shaping gathering sill.The nail 5 that the stitching pocket is used is positioned at the outside of pushing slice of nail 4, places nail shaping gathering sill inside, follows closely foot outwardly, and nail 5 staggers mutually in the position of sewing up head up and down, and two ends of following closely feet of same nail curve inwardly, and are convenient to shaping.At least be provided with a place separately in a side of sewing up head up and down and carry line hole 6, purse wire 22 passes year line hole 6 of sewing up head up and down, between two nail feet of every nail 5.Organize when preventing to sew up excessively, be provided with accordingly at the two ends of sewing up head up and down and organize anti-overflow piece 11.
The both sides of nail bin 3 are provided with gripper shoe 16, are fixed with two leads 14 above the every gripper shoe 16.Correspondingly, be provided with two place's gathering sills 13 about the surface of every shell 1, gathering sill 13 mates mutually with lead 14 makes lead 14 to move up and down along gathering sill 13.And, to sew up between the head up and down and also be provided with a connecting rod 7, connecting rod 7 passes connecting rod cover 15, and connecting rod cover 15 is fixed on above the shell 1.Setting can improve the serviceability of instrument like this, make in the instrument sewing process to locate better, and can be not cause dislocation between higher and lower organizations.
For playing the better application effect, nail 5 is preferably equidistantly arranged, and the rear side of two handles 8 can also be provided with the buckle 9 that cooperatively interacts; And the outside of nail bin 3 can be provided with two and carry wire casing 17, and purse wire 22 is placed in one one and carries within the wire casing 17.The two ends of carrying wire casing 17 respectively have one to be used for purse wire 22 localized small lugs.This structure is convenient to wiring, prevents that purse wire 22 from coming off when not pulling the trigger state.
Pushing slice of nail 4 both can singlely be provided with, and also can a plurality ofly be provided with in groups.A plurality of when being provided with in groups, the bottom links to each other with rectangular 21, as shown in Figure 9.The centre of every pushing slice of nail 4 heads is stators 20, and both sides are two flexure strips 19, and three's top all can be provided with groove, is convenient to place nail 5.
In addition, a bumper bar 10 arranged in that the rear side of a handle 8 is also pivotally connected, it can be got up prop up an other handle 8 during use, sewing up head up and down can not contact.Treating preparation is finished again, it is put down, implement to sew up.Like this, just can prevent the mistake percussion, play safety effect.
This instrument as Figure 10～shown in Figure 12, places the stump of organizing to be sewed up between the nail bin 3 of sewing up head up and down earlier in use, clamps the handle 8 of shell 1 afterbody then, up to buckle 9 fastenings.In this process, two place's nail bins 3 are respectively to sewing up an inner indentation up and down, make push pedal 12 outwards promote pushing slice of nail 4, and then promote to follow closely 5, make nail 5 nail shaping gathering sills move, be out of shape along nail bin 3 inside, two nail feet embed in the middle of the tissue, until forming a closing structure, and purse wire 22 are wrapped in inside.To outward seeming, nail 5 plays the effect of sewing up pocket purse wire 22 nails organizationally.
Stitching finishes, and discharges buckle 9, takes away purse-string suture device, at pack into the associated components of Binding Instrument of organization internal, brings purse wire 22 again together then, and its firm ligation on center-pole, can be finished " bundle pocket " step easily.Finish after this step, the use Binding Instrument just can continue to implement and finish whole bookbinding and perform the operation.
In the application process of the present invention, suitable if nail bin 3 good, purse wire 22 in place is arranged, will improve the effect of instrument.Therefore, can also be at the arranged outside reference column (or locating piece) 23 of nail bin 3, as Fig. 5 and shown in Figure 13, and shell 1 is at relevant position configuration locating hole 18, during installation reference column (or locating piece) 23 is against the bottom of the locating hole 18 of shell 1, makes that two nail bins 3 are in place better up and down.During percussion, under the external force extruding, reference column (or locating piece) 23 ruptures, and does not influence the instrument normal running.
The clamping of purse wire 22, be provided with the scheme of small lugs carrying wire casing 17 two ends except above-mentioned, can also be at special damping block 24 or the reed 25 of the two ends of nail bin 3 configuration, damping block 24 has breach, be installed in above the projection 26 of nail bin 3 both sides, purse wire 22 is placed in the middle of the breach of damping block 24 or reed 25, and the elastic force by the friction of damping block 24 or reed 25 during wiring makes purse wire 22 location, as Figure 13～shown in Figure 17.Adopt after this class scheme, purse wire 22 will be arranged even more ideally, help to prick pocket and even the whole surgery process is carried out smoothly.
Except be provided with carrying line hole 6, of the present invention to plant a kind of embodiment in addition be several wire-fixed clips 27 of arranged outside at the shell 1 of purse-string suture device, as Figure 18～shown in Figure 17.Wire-fixed clip 27 can be made of two relative boss, and purse wire 22 passes two slits between the boss, is positioned between the boss by friction.Add man-hour, wire-fixed clip 27 can be made an integral body with shell 1, also can earlier wire-fixed clip 27 be made individual part, is assembled in then above the shell 1.
It more than is preferred implementation of the present invention.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the scope of protection of present invention.
