At present, the method for processing nail anvil that has the suturing nail grooving of known surgical stapling device is used for processing suturing nail grooving on the nail anvil of surgical stapling device.
Task of the present invention is achieved through the following technical solutions:
The method for processing nail anvil that has the suturing nail grooving of surgical stapling device of the present invention is: adopt non-ferrous alloy to be processed into the matrix of the nail anvil of the surgical stapling device that has above-mentioned suturing nail grooving earlier, adopt electric plating method to process hard suturing nail grooving again on the matrix of above-mentioned nail anvil.The shape of the nail anvil of various surgical stapling devices and structure be existing detailed introduction in United States Patent (USP) 7234624,7168604,6817508,5964394,7147139,7210609,7055730,7140527,7143926 and 7225964.The shape of the suturing nail grooving of the nail anvil of various surgical stapling devices is existing detailed introduction in United States Patent (USP) 6953138 and 20070056932.The nail anvil of the surgical stapling device of other shapes and structure and suturing nail grooving thereof also can adopt the method for processing nail anvil processing that has the suturing nail grooving of above-mentioned surgical stapling device.
Wherein a kind of method for processing nail anvil that has the suturing nail grooving of surgical stapling device is: the method for employing non-ferrous alloy die casting is processed into the nail anvil die casting matrix of the surgical stapling device that has the suturing nail grooving earlier, adopts electric plating method to process hard suturing nail grooving again on nail anvil die casting matrix.When the non-ferrous alloy die-casting process, the nail anvil frame of surgical stapling device can be cast into one as mold insert and nail anvil, or the nail anvil rod of surgical stapling device is cast into one as mold insert and nail anvil, on above-mentioned nail anvil die casting matrix, adopt electric plating method to process hard suturing nail grooving again.
The non-ferrous alloy of die-casting process nail anvil matrix can be selected pack alloy, zinc die casting alloys, press casting copper alloy and diecast magnesium alloy respectively for use according to standard GB/T15115, GB/T13818, GB/T15116 and JB/T3070, also can select the non-ferrous alloy or the metal-base composites of other suitable die-casting process nail anvil matrixes for use.Can also select U.S. ZA27 high alumina zinc base alloy for use to the nail anvil die casting that high strength requires, the non-ferrous alloy or the metal-base composites of the nail anvil matrix that the high strength die-casting aluminum alloy of China YL113, Japanese ADC12 and the U.S. 380.0 or other suitable die-casting process high strength require.(mould practical technique book series editorial board compiles about be chosen in " the design of Die Casting application example " of design, extrusion process and the die casting machine of the design of the selection of the diecasting alloys of non-ferrous alloy die-casting process, die casting, die casting.Beijing; China Machine Press, 2005.6) in detailed introduction is arranged, can be used as reference, in the method for processing nail anvil that has the suturing nail grooving of surgical stapling device of the present invention, be used to process the non-ferrous alloy die casting matrix of the nail anvil of the surgical stapling device that has the suturing nail grooving.
Because the dimensional accuracy of die casting is IT12-IT11, surface roughness Ra is generally 3.2-0.8 μ m, minimumly reaches 0.4 μ m, so the nail anvil die casting can be without machining or only be that indivedual positions finished machined can be used.Because the chilling action of compression mod, the die casting of crystallization under pressure, so nail anvil again surface layer crystal grain is thinner, and dense structure is so the hardness of nail anvil die casting surface layer and intensity are all than higher.Because the die casting forming process is filling under pressure all the time and solidifies, therefore come out for die casting clearly such as profile peak valley, convex-concave, narrow grooves, be convenient to adopt pressure casting method to process and be used for the nail anvil matrix that has the suturing nail grooving of the different shape of circular anastomosis device, linear stiching instrument, linear cut stapler or chamber mirror surgical stapling device.Owing to can inlay other metals of die casting or nonmetallic materials part when die casting is produced, therefore the nail anvil frame or the nail anvil rod of surgical stapling device can be cast into one as mold insert and nail anvil, replace assembling and simplified manufacturing technique with these parts, improve the service behaviour of nail anvil die casting.Thereby the nail anvil working (machining) efficiency that has the suturing nail grooving that reaches surgical stapling device is higher, better quality, purpose that cost is lower.

2, ingate thickness is 1mm, air discharge duct connects the about 5mm of the die cavity gross area
2, the about 11.7cm of overflow launder cumulative volume
3, account for blank volume 18.5%.Chromium plating requires the no current mark in surface, and therefore the cold shut vestige that cause without any the eddy current owing to molten metal on promptly whole surface wishes that loading time is very short, and loading time is got 0.015s.This routine ingate sectional area is obtained very big, because adopt evacuated die-casting process, needn't consider exhausting problem, die cavity filling rapidly.
Employing evacuated die-casting process can significantly reduce the pore in the foundry goods, increases the density of foundry goods, has improved the mechanical property of foundry goods; Eliminated the blemish that pore causes, improved the surface quality of foundry goods, suitable machining shape complexity, the high foundry goods of required precision; The inner pore-free of foundry goods can be heat-treated.Each Vacuum Die Casting Mould can be processed 200,000 of the nail anvil die casting matrixes (2 of every moulds) of the linear stapler that has the suturing nail grooving, and every work team can process 1000, improves working (machining) efficiency greatly, reduces cost.
The technical process of durionise processing suturing nail grooving is on the high alumina zinc base alloy die casting matrix of nail anvil: high alumina zinc base alloy die casting matrix polishing oil removing → employings of nail anvil activating process acid and alkalescence is handled binding force of cladding material with raising high alumina zinc base alloy die casting → to the pre-brass plating → hard chrome plating of high alumina zinc base alloy die casting.The chromium coating thickness range is 0.02mm-0.05mm.The hardness of chromium coating reaches HV8000MPa, can electroplate on the high alumina zinc base alloy die casting matrix of nail anvil and process hard suturing nail grooving.At the prescription of zinc-containing alloy plating hard chromium on surface with technical process can (Hu Runan, Chen Songqi writes with reference to " practical chromium plating technology ".Beijing; National Defense Industry Press, 2005.7).
Two of the method for processing nail anvil that has the suturing nail grooving of surgical stapling device:
The method of employing non-ferrous alloy die casting is processed into the nail anvil die casting matrix of the circular anastomosis device that has the suturing nail grooving, the nail anvil rod of circular anastomosis device is cast into one as mold insert and nail anvil, the ADC12 high strength die-casting aluminum alloy that casting material adopts home-made YL113 or Japan to produce, foundry goods requires pore-free and does not allow defectives such as loose and crackle, surface requirements is smooth, carries out chromium plating.
