Specific embodiment
In order that those skilled in the art more fully understand that technical scheme can be practiced, below in conjunction with the accompanying drawingsThe invention will be further described with specific embodiment, but illustrated embodiment is not as a limitation of the invention.
A kind of the invention provides safeties of hernia stapler, and the hernia stapler for applying the safeties.Please joinRead shown in Fig. 1-Fig. 9, the safeties of the hernia stapler that the present invention is provided, including housing 1, flexible handle 2, be fixed on housing 1Interior elastic parts 5 and the safe sliding block 4 being rotatably connected in housing 1, safe sliding block 4 is with first end 42 and secondEnd 45, its first end 42 can be spacing by 5 clamping of elastic parts, and the second end 45 can be upper with the flexible handle 2End face 22 offsets, and is fixed with insurance push button 6 on safe sliding block 4.
Preferably, the safeties of the hernia stapler that the present invention is provided can also include fixed block 3, and the fixed block 3 is fixedIt is installed in housing 1, above-mentioned fixed block 3 has the cavity with groove, and is provided with safe sliding block installing hole 311,322, above-mentioned bulletProperty component 5 be fixed in 3 cavity of fixed block, above-mentioned safe sliding block 4 is slided with set insurance in 3 cavity of fixed block by rotating shaft 43Block installing hole 311,322 is flexibly connected, and the first end 42 of elastic parts 5 and safe sliding block 4 contacts.The setting of fixed block 3,So that elastic parts 5 and safe sliding block 4 is fixed and positioned more convenient and firm.
Wherein, refer to shown in Fig. 3, above-mentioned safe sliding block 4 includes body construction 41, the body is provided with first end42nd, the second end 45, rotating shaft 43 and push rod 44, rotating shaft 43 Wei Yu first end 42 and the second end 45 between, push rod 44Between rotating shaft 43 and the second end 45, rotating shaft 43 and push rod 44 are each passed through two holes and insurance on safe sliding block body 41Slider body 41 connects.
Preferably, above-mentioned safe sliding block first end 42 is arranged to lozenges, and the cross section of the second end 45 is rectangle.
Refer to shown in Fig. 4-8, above-mentioned fixed block 3 is internal to have two cavitys, and the first cavity 33 is used for accommodating and fixingElastic parts 5, the second cavity 34 are used for accommodating portion safe sliding block 4, and 34 side wall of the second cavity is additionally provided with a pair of safe sliding block peaceDress hole 311,322, for connecing with 43 axle of rotating shaft on above-mentioned safe sliding block 4.
Specifically, the rotating shaft 43 of above-mentioned safe sliding block 4 is located in safe sliding block installing hole 311,322 respectively with two ends,Connection is rotated so as to be formed.Safe sliding block 4 is rotated with above-mentioned rotating shaft 43 as axle, and the first end 42 of safe sliding block 4 is located to be fixedIn second cavity 34 of block 3, the second end 45 is located at the outside of fixed block 3.
Preferably, above-mentioned fixed block 3 includes to fix block body 32 and fixing lid 31, and fixing 32 lateral surface of block body is provided withFixture block 321,31 lateral surfaces of fixing lid are provided with the draw-in groove 312 for mating clamping with the fixture block 321 on fixing 32 lateral surface of block body,Fixing block body 32 and fixing lid 31 are fixed the fixed block 3 to form one end with groove.
Another kind of scheme is：The lateral surface of above-mentioned fixing block body 32 arranges draw-in groove 312, correspondingly, above-mentioned fixing lid 31Upper setting fixture block 321, so as to form fixed block 3 of the one end with groove.
Preferably, above-mentioned safe sliding block installing hole 311,322 is separately positioned on fixing lid 31 and fixing block body 32, toolBody is lower end side.
Above-mentioned elastic parts 5 includes spring 52 and spacing spheroid 53, when elastic parts 5 is placed in the first cavity of above-mentioned fixed blockWhen in 34, one end of spring 52 and 34 bottom connection of the first cavity are touched, and the other end and spacing spheroid 53 contact or connect, spacingSpheroid 53 is limited in the by the limited step of the limited step that arranges between the first cavity 34 and the second cavity 35 or formationIn one cavity 34.
Preferably, above-mentioned elastic parts 5 can also include spring fixed pedestal 51, and spring fixed pedestal 51 is chuck structureOr draw-in groove, when for chuck structure, 52 one end of spring is socketed in chuck structure, and the other end and spacing spheroid 53 contact or phaseConnection；When for draw-in groove, 52 one end of spring is connected in draw-in groove, and the other end contacts with spacing spheroid 53 or is connected, soSetting make the stability of elastic parts 4 in the first cavity 34 more preferable.
As above-mentioned safe sliding block 4 can be rotated in the second cavity 35 of fixed block 3 by rotating shaft 43, therefore, work as guarantorWhen dangerous slide block 4 is rotated, the first end 42 of safe sliding block 4 forces in spacing spheroid 53, the first compression spring 52 of spacing spheroid 53, theOne end 42 moves to insurance open position 35 from initial insurance locked position 36, and then spring 52 is voluntarily discharged, will4 first end 42 of safe sliding block is limited in insurance open position 35.
Above-mentioned spacing spheroid 53 is steel ball or plastic bead.
Refer to shown in Fig. 9, safe sliding block chute 11 on above-mentioned housing 1, is provided with, the push rod 44 of safe sliding block 4 is through guarantorDangerous slide block chute 11 is connected with insurance push button 6, manually promotes insurance motion of the push button 6 in safe sliding block chute 11,So that above-mentioned safe sliding block 4 is rotated by rotating shaft 43.
Fixed block installing hole 13 and the positioning bar 14,15 for fixing fixed block 3 are additionally provided with above-mentioned housing 1, protectSafe sliding block installing hole 311,322 and the interior installing hole for arranging of housing that rotating shaft 43 on dangerous slide block 4 is arranged through on fixed block 313 axles connect, and by the spacing of positioning bar 14,15, by 3 location and installation of fixed block inside housing 1.
Flexible handle 2 is rotatably coupled on the bearing pin 12 of housing by its installing hole 21, meanwhile, by 7 He of extension springHousing 1 is connected, and specifically, 7 one end of extension spring is fixed on the snap clasp 23 of flexible handle 2, and the other end is fixed on housingSpring fixed part 16 on, so that flexible handle 2 is rotated and be resetted.
Above-mentioned flexible handle 2 also has the upper surface 22 that can be offseted with 4 the second end 45 of above-mentioned safe sliding block.
During original state, in cock is treated, the first end 42 of safe sliding block 4 receives fixed block 3 second to flexible handle 2Cavity 35 and spacing spheroid 53 spacing, in initial insurance locked position 36, and the second end 45 is then against flexible handle 2Upper surface 22 on, so that flexible handle 2 is rotated, apparatus can not be closed, and reach the purpose of locking.
During work, promote insurance push button 6 final position to be moved to by initial position in safe sliding block chute 11 manually, enterAnd cause in safe sliding block installing hole 311,322 of the safe sliding block 4 by the rotating shaft 43 set by which on fixed block 3 counterclockwiseRotate so that before by spacing for safe sliding block first end 42 elastic parts 5 in initial insurance locked position 36, in thrustIt is released after first being compressed under effect, most safe sliding block first end 42 is spacing in insurance open position 35 at last；And insureSlide block the second end 45 then departs from the upper surface 22 of flexible handle 2, insures in open mode, you can pull flexible handle, fromAnd drive intraware to complete percussion.
Embodiment described above is only the preferred embodiment that is lifted for absolutely proving the present invention, the protection model of the present inventionEnclose not limited to this.Equivalent substitute or conversion that those skilled in the art are made on the basis of the present invention, all in the present inventionProtection domain within.Protection scope of the present invention is defined by claims.
