Abstract
The invention relates to a nail-pushing seat assembly of an intracavitary cutting stapling device. The nail-pushing seat assembly comprises a nail-pushing seat and a nail-pushing seat cover plate connected with the back side of the nail-pushing seat and used for sealing an open part of the nail-pushing seat. The nail-pushing seat is made by a powder metallurgical method. The working surface of the nail-pushing seat is provided with regularly-arrayed nail pits which are integrally formed with the working surface of the nail-pushing seat. Grooves for installing the nail-pushing seat cover plate are arranged on the periphery of the back side of the nail-pushing seat. Protruding retaining sides integrally formed with the side surface of the nail-pushing seat are arranged on the side surface of the nail-pushing seat. The nail-pushing seat assembly of the intracavitary cutting stapling device has following beneficial effects: the nail-pushing seat is made by the powder metallurgical method; the nail pits are made uniformly and neatly; the differently-sized nail pits are obtained in the manner of adjusting a powder metallurgy die; by means of the grooves in the back side of the nail-pushing seat, the nail-pushing seat and the nail-pushing seat cover plate can be welded and fixed and positioned accurately so that attractiveness and convenience are obtained; by means of the integrated design of the nail-pushing seat and the protruding retaining sides at two sides, machining technology of the nail-pushing seat cover plate is simplified; and higher practicability is obtained.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of nail supporting base assembly of intracavity Endo-GIA.
Background technology
Traditional intracavity Endo-GIA nail supporting base processing is loaded down with trivial details, the operations such as shaping, impression, jet-bedding need be completed through too much mold, and nail hole shape poor consistency, often apparatus all to be done necessary adjustment, had a strong impact on production efficiency because nail shape debug difficulties and caused the waste of resource.
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 intracavity Endo-GIA.
The present invention solves the technical scheme that its technical problem adopts: a kind of nail supporting base assembly of intracavity Endo-GIA, comprise nail supporting base and the nail supporting base cover plate sealed by nail supporting base open section being connected to the nail supporting base back side, nail supporting base adopts powder metallurgy process to make, nail supporting base work surface is provided with the nail hole of marshalling integrated with it, the back side periphery of nail supporting base offers the groove installing nail supporting base cover plate, and the side of nail supporting base is provided with the rib of projection integrated with it.
Further, the centre of nail supporting base offers tool slot, and the transition position of rib and nail supporting base adopts multi-section circular arc splicing.
Further, the nail hole quantity 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; Nail supporting base and nail supporting base cover plate can be welded and fixed by the groove at the nail supporting base back side, accurate positioning, convenience attractive in appearance; By the design that the protruding rib in nail supporting base and both sides is integrated, simplify the processing technique of nail supporting base cover plate, practicality is stronger.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the upward view of nail supporting base;
Fig. 3 is the top view of nail supporting base.
Wherein: 1. nail supporting base, 2. nail supporting base cover plate, 3. nail hole, 4. rib, 5. groove.
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 intracavity Endo-GIA as shown in Figures 1 to 3, comprise nail supporting base 1 and the nail supporting base cover plate 2 sealed by nail supporting base 1 open section being connected to nail supporting base 1 back side, nail supporting base 1 adopts powder metallurgy process to make, nail supporting base 1 work surface is provided with the nail hole 3 of marshalling integrated with it, the back side periphery of nail supporting base 1 offers the groove 5 installing nail supporting base cover plate, and the side of nail supporting base 1 is provided with the rib 4 of projection integrated with it.
The centre of nail supporting base 1 offers tool slot, and rib 4 adopts multi-section circular arc splicing with the transition position of nail supporting base 1, has effectively saved space, ensure that unimpeded in perforator sheath pipe of assembly.
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 1 adopts powder metallurgy process to make, and it is evenly regular that 3 sizes cheated by obtained nail, and can by the nail hole 3 regulating the mode of powder metallurgy die to obtain different size.Nail on nail supporting base 1 is cheated 3 quantity and is increased with the increase of nail supporting base 1 length or reduction or reduce.
Rib 4 is one-body molded with nail supporting base 1, and simplify the processing technique of nail supporting base cover plate 2, practicality is stronger.
Nail supporting base 1 and nail supporting base cover plate 2 are assembled rear laser weld by the groove 5 at nail supporting base 1 back side fix, accurate positioning, convenience attractive in appearance.
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.
