Abstract
The invention relates to a nail pushing seat assembly of an anorectal stapler device. The nail pushing seat assembly comprises a nail pushing seat and a guide shaft mounted at the center of the nail pushing seat. The nail pushing seat and the guide shaft are made to be of an integral structure by adoption of a powder metallurgy method. The lower surface of the nail pushing seat is provided with orderly-arrayed nail pits integrally formed with the lower surface thereof. A connecting hole, communicating the nail pushing seat with the guide shaft, used for connecting with a cover cap is formed in an axial direction. Guide ribs integrally formed with the outer side surface of the guide shaft are distributed on the guide shaft. The nail pushing seat assembly of the anorectal stapler device has following beneficial effects: the nail pushing seat is made by the powder metallurgy method; nail pits are of uniform and standard size; differently-sized nail pits are obtained by the mode of adjusting a powder metallurgy die; the guide ribs and the guide shaft are internally formed; the production technology is simple; positions of the guide ribs and the guide shaft are fixed; during assembly, the guide shaft is positioned more accurately; the cover cap made by plastic material is fixed at the top of the nail pushing seat by means of the connecting hole; and technology 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 anorectal anastomat.
Background technology
The nail supporting base of traditional anorectal anastomat is Split type structure, the axis of guide and nail supporting base machine-shaping respectively, two parts connect for overall structure by the mount pad bottom nail supporting base by the axis of guide, guiding rib outside the axis of guide adopts the mode of injection mo(u)lding or finishing impression processing to make, its manufacturing process is complicated, long processing time, 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 anorectal anastomat.
The present invention solves the technical scheme that its technical problem adopts: a kind of nail supporting base assembly of anorectal anastomat, comprise nail supporting base and the axis of guide being installed on nail supporting base center, nail supporting base and the axis of guide adopt powder metallurgy process to make integrative-structure, nail supporting base lower surface is provided with the nail hole of marshalling integrated with it, nail supporting base and the axis of the axis of guide offer the connecting hole for being connected block of connection, and axis of guide outer surface is distributed with guiding rib integrated with it.
Further, the nail hole quantity on nail supporting base is large or reduce and increase accordingly or reduce according to the change of nail supporting base diameter.
Further, on nail supporting base several circles uniform subtract muscle hole.
Further, nail supporting base is the boss structure of increasing diameter from top to down.
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; Guiding rib and the axis of guide one-body molded, processing technology is simple, and the position of guiding rib and the axis of guide is fixed, and the location in axis of guide assembling process is more accurate; The block of plastic material is fixed on the top of nail supporting base by connecting hole, simplify technique, 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 upward view of the present invention;
Fig. 3 is sectional view of the present invention.
Wherein: 1. nail supporting base, the 2. axis of guide, 3. nail hole, 4. connecting hole, 5. guiding rib, 6. 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 anorectal anastomat as shown in Figures 1 to 3, comprise nail supporting base 1 and the axis of guide 2 being installed on nail supporting base 1 center, nail supporting base 1 and the axis of guide 2 adopt powder metallurgy process to make integrative-structure, nail supporting base 1 lower surface is provided with the nail hole 3 of marshalling integrated with it, nail supporting base 1 and the axis of the axis of guide 2 offer the connecting hole 4 for being connected block of connection, and the axis of guide 2 outer surface is distributed with guiding rib 5 integrated with it.
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.It is large or reduce and increase accordingly or reduce according to the change of nail supporting base 1 diameter that 3 quantity cheated by nail on nail supporting base 1.
Nail supporting base 1 and the axis of guide 2 adopt powder metallurgy process to make integrative-structure, make nail supporting base 1 and the axis of guide 2 junction eliminate original installation base, release certain space, increase the capacity of tissue.
Guiding rib 5 is one-body molded with the axis of guide 2, and processing technology is simple, and guiding rib 5 is fixed with the position of the axis of guide 2, and the location in axis of guide assembling process is more accurate.On the axis of guide 2, the distribution of guiding rib 5 changes accordingly with the distribution of nail supporting base being followed closely hole.
The block of plastic material is fixed on the top of nail supporting base 1 by connecting hole 4, simplify technique, practicality is stronger.
On nail supporting base 1 several circles uniform subtract muscle hole 6, effectively alleviate the weight of assembly, use lighter.
Nail supporting base 1 is the boss structure of increasing diameter from top to down.Design is optimized to the upper surface moulding of nail supporting base 1, reduces maximum outside diameter, reduce integral thickness, the space-saving secondary injury simultaneously reduced anastomotic stoma.
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.
