Detailed description of the invention
Present invention is disclosed a kind of Linear stapler, as shown in Figure 1, consistent with prior art, comprising: housing 1, the support 2 be fixed on housing 1, be arranged at the nail anvil 3 of support 2 far-end, and a pivot is arranged at the percussion handle 4 on support 2.Linear stapler of the present invention also comprises a nail bin groupware 5, and concrete with reference to shown in Fig. 2, described nail bin groupware comprises the nail bin frame 6 that plug-in is located at rack far end, is provided with the ejector pin film perforation 8 passed for pushing slice of nail 7 in described nail bin frame.The shape of described pushing slice of nail 7 is all consistent with prior art with arrangement, for inside and outside two rows are staggered.
Be provided with a columniform rotary-type nail bin 9 in described nail bin frame 6, the periphery of described rotary-type nail bin be evenly equipped with at least 2 group nail 10, be 3 groups in this example, namely often the center of circle angle organized between nail 10 is 60 °, and one group of nail 10 is 2 staggered rows.Often organize nail 10 all recessed on blow fermentation 16.Be connected in columniform periphery in described percussion face 16.
All be placed with suturing nail in each nail 10, each nail 10 is through the periphery of rotary-type nail bin 9.The rotating shaft mechanism for making described rotary-type nail bin 9 rotate relative to nail bin frame 6 is provided with between described rotary-type nail bin 9 and nail bin frame 6, and for the wherein nail 10 of a group and described ejector pin film perforation 8 position-limit mechanism one to one described in optionally making.Described rotating shaft mechanism and position-limit mechanism form selecting apparatus of the present invention.
Specifically, described rotating shaft mechanism comprises two rotating holes 11 be located on described nail bin frame, and the corresponding rotating shaft 12 being located at two end faces of described rotary-type nail bin 9 respectively, and described rotating shaft 12 can insert in described rotating hole 11.Certainly, the position of rotating hole 11 and rotating shaft 12 also can exchange, and certainly, also can adopting the pin-and-hole structure except disclosing in this case, still can adopt other pivot structures, such as, increase bearing etc.
Described position-limit mechanism comprises the groove 13 be located on described nail bin frame 6, and the corresponding position rotating muscle 14 being located at the end face of described rotary-type nail bin 9.In this example, described nail bin frame is provided with symmetrically two extensions 15, the relative surface of described two extensions 15 is respectively provided with a groove 13, described groove 13 respectively on two extensions 15 is coplanar.Described each groove 13 is all through described rotating hole 11, and described each position rotating muscle 14 is all through described rotating shaft 12.In this example, often organize a nail 10 i.e. corresponding position rotating muscle 14.When described position rotating muscle 14 snaps in described groove 13, the described wherein nail 10 of a group and described ejector pin film perforation 8 one_to_one corresponding.
Preferably, as shown in Figure 3, the cross section of described position rotating muscle 14 comprises right-angle side 141 and a round edge 142 respectively.Like this, when described rotary-type nail bin 9 rotates, only allow to enter in groove 13 from round edge 142 side, this prevents the reversing of described rotary-type nail bin 9.
Underdraw the operating process of the present embodiment below.
Under original state, have one group of nail 10 corresponding with described ejector pin film perforation 8, now pull the trigger face 16 formative tissue relative to nail anvil and pull the trigger region, described percussion face 16 is all parallel with relative nail anvil face 17, ejector pin frame surface 18 immediately.When needs are pulled the trigger, pushing slice of nail 7 can directly enter in ejector pin film perforation 8 and nail 10, is pushed out of outside nail 10 by the suturing nail in nail 10.Then by clockwise or counterclockwise direction rotating wheel formula nail bin 9, direction of rotation is depending on the place of round edge 142.Snap in after in described groove 13 when organizing the corresponding position rotating muscle 14 of nail 10 to next, then this group nail 10 is namely corresponding with described ejector pin film perforation 8 instantly.At this moment percussion can just be continued.In like manner, the suturing nail in the nail of the 3rd group is pulled the trigger after the same method.After the suturing nail in three groups of nail is all by percussion, now can the prompting of colored or sound, at this moment just need to change whole nail bin groupware.
Fig. 4 discloses the second embodiment of the present invention, and the periphery being described rotary-type nail bin 9 with the difference of the first embodiment is evenly equipped with 2 groups of nail 10, and namely often the center of circle angle organized between nail 10 is 90 °, and all the other all features are all identical with the first embodiment.Such the present invention can complete the function repeatedly pulled the trigger.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of being formed, all drop within the scope of protection of present invention.
