Abstract
The present invention relates to a staple holder assembly of a cutter stapler. The staple holder assembly comprises a staple head, and a staple holder frame and a staple holder which are stacked up and down and connected to the rear end portion of the staple head; the staple head and the staple holder are prepared to be an integral structure by utilization of the powder metallurgy method; a working face of the staple holder is provided with staple pits which are integratedly moulded with the staple holder and are arranged orderly; a staple holder surface connected with the staple holder frame is provided with positioning pins integratedly moulded with the staple holder; the staple holder frame is provided with positioning holes cooperated with the positioning pins; and an end portion of the staple holder is provided with positioning bosses integratedly moulded with the staple holder. The staple holder assembly has the beneficial effects that the staple holder is prepared by the powder metallurgy method, the prepared staple pits are uniform in size and are arranged in order, and the staple pits having different sizes can be obtained by adjusting a powder metallurgy die; the positioning bosses are integratedly moulded with the staple holder, and the staple holder and the staple holder frame are positioned more accurately; and the staple holder and the staple holder frame are fixed by laser welding, and according to cooperation of the positioning pins and the positioning holes, the staple holder frame and the staple holder are abutted and fixed conveniently.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of nail supporting base assembly of Endo-GIA.
Background technology
Traditional Endo-GIA nail supporting base assembly adds man-hour, bending and molding after cavity internal lining mandrel, extrude nail hole on nail supporting base surface again, pound out plug after having impressed, manufacturing process is loaded down with trivial details, efficiency is low, and often apparatus all to be done necessary adjustment in the past, to ensure to follow closely the accurate of position, hole, the nail hole specification of preparation is like this difficult to unified, often there is heterogeneity phenomenon, have a strong impact on the nail shape of Endo-GIA.In addition, traditional Endo-GIA support ailhead be the plastic construction of split, need polish flat during assembling, time-consuming, inefficiency, globality is bad.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of nail supporting base assembly of Endo-GIA.
The present invention solves the technical scheme that its technical problem adopts: a kind of nail supporting base assembly of Endo-GIA, comprise to ailhead, mounted on top is connected to nail supporting base frame to ailhead rearward end and nail supporting base, powder metallurgy process is adopted to make integrative-structure to ailhead and nail supporting base, nail supporting base work surface is provided with the nail hole of marshalling integrated with it, the nail supporting base surface be connected with nail supporting base frame is provided with alignment pin integrated with it, nail supporting base frame offers the locating hole matched with alignment pin, nail supporting base end is provided with the positioning boss of being convenient to nail supporting base frame be located by connecting integrated with it.
Further, nail supporting base and nail supporting base frame laser weld are overall structure.
Further, what on ailhead, to offer etc. wall thickness subtracts muscle hole.
Further, the quantity in the nail hole on nail supporting base increases with the increase of nail supporting base length or reduction or reduces.
The invention has the beneficial effects as follows: nail supporting base adopts powder metallurgy process to make, obtained nail hole size is evenly regular, and can by the nail hole regulating the mode of powder metallurgy die to obtain different size; Positioning boss and nail supporting base one-body molded, the position of positioning boss and nail supporting base is fixed, and it is more accurate that nail supporting base and nail supporting base frame are located; Nail supporting base and nail supporting base frame laser weld are fixed, simplify technique, practicality is stronger, and relies on the cooperation of alignment pin and locating hole, facilitates nail supporting base frame to fix with docking of nail supporting base.

Fig. 2 is the schematic diagram one to ailhead and nail supporting base integrative-structure;
Fig. 3 is the structural representation of nail supporting base frame;
Fig. 4 is the schematic diagram two to ailhead and nail supporting base integrative-structure.
Wherein: 1. support ailhead, 2. nail supporting base frame, 3. nail supporting base, 4. nail hole, 5. alignment pin, 6. positioning boss, 7. subtract muscle hole.
Detailed description of the invention
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to the present invention instead of limitation of the invention further are described.
The nail supporting base assembly of a kind of Endo-GIA as shown in figures 1-4, comprise to ailhead 1, mounted on top is connected to nail supporting base frame 2 to ailhead 1 rearward end and nail supporting base 3, powder metallurgy process is adopted to make integrative-structure to ailhead 1 and nail supporting base 3, nail supporting base 3 work surface is provided with the nail hole 4 of marshalling integrated with it, nail supporting base 3 surface be connected with nail supporting base frame 2 is provided with alignment pin 5 integrated with it, nail supporting base frame 2 offers the locating hole matched with alignment pin 5, nail supporting base 3 end is provided with the positioning boss 6 of being convenient to nail supporting base frame 2 be located by connecting integrated with it.
Nail supporting base 3 and nail supporting base frame 2 laser weld are overall structure.
Powder metallurgy be produce metal dust or with metal dust (or mixture of metal dust and non-metal powder) as raw material, through shaping and sintering, produce the industrial technology of metal material, composite and all kinds goods.At present, PM technique has been widely used in the fields such as traffic, machinery, electronics, Aero-Space, weapons, biology, new forms of energy, information and nuclear industry, becomes one of branch of most development vitality in new material science.PM technique possess significantly energy-conservation, economize the high and series of advantages such as good stability of material, excellent performance, Product Precision, the batch production of the production in enormous quantities being very suitable for part and the part with labyrinth.
Nail supporting base 3 adopts powder metallurgy process to make, and it is evenly regular that 4 sizes cheated by obtained nail, and can by the nail hole 4 regulating the mode of powder metallurgy die to obtain different size.
Positioning boss 6 is one-body molded with nail supporting base 3, and positioning boss 6 is fixed with the position of nail supporting base 3, and it is more accurate that nail supporting base 3 and nail supporting base frame 2 are located.
Nail supporting base 3 and nail supporting base frame 2 laser weld are fixed, simplify technique, practicality is stronger, and relies on the cooperation of alignment pin 5 and locating hole, facilitates nail supporting base frame 2 to fix with docking of nail supporting base 3.
What on ailhead 1, the wall thickness such as to offer subtracts muscle hole 7, ensure that the full of accessory appearance and alleviates overall weight.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, must determine its technical scope according to right.
