The specific embodiment

This utility model has disclosed a kind of automatic purse stitching instrument used for surgery, in conjunction with illustrated in figures 1 and 2, the same with prior art, comprise that similar shears is equally by two hinged handle holders 1 of pin 4, the afterbody of handle holder 1 is grip part 2, front end is to be provided with bumper bar between 3, two handle holders 1 of suturing part.

Be provided with nail casket 5 and pushing slice of nail 10 in the described suturing part 3, described nail casket 5 removably is connected on the handle holder 1, is convenient to change; Described pushing slice of nail 10 is fixed on the handle holder 1.In the present embodiment, all be provided with corresponding nail casket 5 on the handle holder 1, and nail casket 5 is laterally to place.

Longitudinally be set with a guide rod 9 in the described nail casket 5, this guide rod 9 is the hollow setting, and purse wire 14 can pass from its inside.Be provided with nail row 6, actuator 7 and driving spring 8 from front to back successively along guide rod 9, nail row 6 is arranged on the front end of guide rod 9, and actuator 7 is located between nail row 6 and the driving spring 8, and the three is set on the guide rod 9.Described nail row 6 forms the sensing unanimity of its nail foot for some nails arrangements.One end of described driving spring 8 is against on the actuator 7, and the other end is against on the inwall of nail casket 5, and when original state, driving spring 8 produces a thrust to actuator 7, and nail row 6 is played an effect that promotes forward.

In the present embodiment, nail row 6 nail foremost is against on the nail bin 11, and described nail bin 11 is movably arranged on the front end of nail casket 5, comprises one and goes out nail mouth 12.Nail bin 11 can slide with respect to nail casket 5.Since pushing slice of nail 10, nail row 6 foremost a nail and go out nail mouthfuls 12 and be positioned at same plane, when holding grip part 2 with a firm grip, two relative nail bin 11 mutual extrusion, and retreat to the suturing part 3 of handle holder 1 separately, pushing slice of nail 10 promptly advanced, and was pushed out of out nail mouth 12 being positioned at nail row 6 nail foremost with respect to nail bin 11 this moment.Be provided with a back-moving spring 13 between the suturing part 3 of described nail bin 11 and handle holder 1, when grip part 2 is released, make nail bin 11 can be returned to original state.Hold, unclamp grip part 2 repeatedly with a firm grip, can in turn order tissue to whole nail row's 6 nail and get on, the process of its work is similar to stapler.

Introduce the installation and the using method of present embodiment below.

At the nail purse wire 14 of packing in the casket 5, then at the nail driving spring 8 of packing in the casket 5, one end of spring is fixedlyed connected with nail casket inwall, the other end is against actuator 7, in nail casket 5, put into a nail row 6, make an end of nail row 6 be against the inwall that is arranged on the nail bin 11 of following closely the casket front end, the other end is against on the actuator 7.What at this moment, the nail foot that comes nail was foremost aimed at nail bin 11 goes out nail mouthfuls 12.Identical method installs four nail caskets.Place a back-moving spring 13 at the front end of handle holder 1 then, will follow closely casket simultaneously and pack on the handle holder 1, make an end of back-moving spring 13 be against the suturing part 3 of handle holder 1, the other end is against on the nail bin 11.At last two handle holders, 1 usefulness pin is scissor and couples together, at this moment, pouching device installs.

During use, open handle holder 1, make between the relative up and down nail casket 5 and present certain space, tissue is put into this space, the grip part 2 of holding handle holder 1 near-end then with a firm grip, the casket of nail up and down 5 that be positioned at handle holder 1 far-end this moment pushes mutually, the back-moving spring 13 that is positioned at handle holder 1 front end is compressed, so nail bin 11 is drawn back, and then nail is extruded out from going out nail mouthfuls 12 by pushing slice of nail 10, and orders tissue.Because purse wire 14 is between two nail feet, after nail was shaped, purse wire 14 was enclosed between nail and the tissue.Open apparatus then, finish the stitching process one time.The doctor can be on demand the length of purse string suture carry out the action that several times are sewed up.

Fig. 3 and Fig. 4 have disclosed second embodiment of the present utility model, are with first embodiment difference: all be provided with corresponding nail casket 5 on the handle holder 1, and this nail casket 5 is vertical placement on handle holder 1.The installation of the apparatus of present embodiment is similar to first embodiment with use, and unique difference is that first embodiment is vertical gripping, stitching when in use; And present embodiment is laterally to grip, sew up.This utility model still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of this utility model.
