Abstract
The invention relates to a nail pushing seat assembly for a tubular stapler device. The nail pushing seat assembly comprises a nail pushing seat and a clamp spring tube installed at the center of the nail pushing seat. The nail pushing seat and the clamp spring tube are of an integral structure by adoption of a powder metallurgy method. The lower surface of the nail pushing seat is provided with neatly-arranged nail pits integrally formed with the lower surface thereof. The axial direction of the nail pushing seat is provided with a connecting hole used for placing a clamp spring sheet communicating the clamp spring tube. The upper surface of the nail pushing seat is provided with a clamp groove for installing a cover cap. Guide ribs integrally formed with the outside surface are distributed on the outside surface of the clamp spring tube. The nail pushing seat assembly for the tubular stapler device has following beneficial effects: the nail pushing seat is made by a powder metallurgy method so that the nail pits are made uniformly and orderly; differently-sized nail pits are acquired by the method of adjusting a powder metallurgy die; the guide ribs and the clamp spring are integrally formed; a simple production process is obtained; positions of the guide ribs and the clamp spring are fixed; the clamp spring tube is positioned more accurately during assembly; and the cover cap made by plastic material is fixed at the top of the nail pushing seat by means of the clamp groove so that process 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 tubular anastomat.
Background technology
The nail supporting base of traditional tubular anastomat is Split type structure, jump ring pipe and nail supporting base machine-shaping respectively, two parts connect for overall structure by the mount pad bottom nail supporting base by jump ring pipe, guiding rib outside jump ring pipe 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 tubular anastomat.
The present invention solves the technical scheme that its technical problem adopts: a kind of nail supporting base assembly of tubular anastomat, comprise nail supporting base and the jump ring pipe being installed on nail supporting base center, nail supporting base and jump ring pipe adopt powder metallurgy process to make integrative-structure, nail supporting base lower surface is provided with the nail hole of marshalling integrated with it, the axis of nail supporting base offers the connecting hole for placing Clip Reed of through jump ring pipe, nail supporting base upper surface offers the draw-in groove installing block, and jump ring pipe 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, 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 jump ring pipe one-body molded, processing technology is simple, and the position of guiding rib and jump ring pipe is fixed, and the location in jump ring pipe assembling process is more accurate; The block of plastic material is fixed on the top of nail supporting base by draw-in groove, 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, 2. jump ring pipe, 3. nail hole, 4. connecting hole, 5. draw-in groove, 6. guiding rib.
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 tubular anastomat as shown in Figures 1 to 3, it is characterized in that: comprise nail supporting base 1 and the jump ring pipe 2 being installed on nail supporting base 1 center, nail supporting base 1 and jump ring pipe 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, the axis of nail supporting base 1 offers the connecting hole 4 for placing Clip Reed of through jump ring pipe 2, nail supporting base upper surface offers the draw-in groove 5 installing block, and jump ring pipe 2 outer surface is distributed with guiding rib 6 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.
Nail supporting base 1 and jump ring pipe 2 adopt powder metallurgy process to make integrative-structure, make nail supporting base 1 and jump ring pipe 2 junction eliminate original installation base, release certain space, increase the capacity of tissue.
Guiding rib 6 is one-body molded with jump ring pipe 2, and processing technology is simple, and guiding rib 6 is fixed with the position of jump ring pipe 2, and the location in jump ring pipe 2 assembling process is more accurate.On jump ring pipe 2, the distribution of guiding rib 6 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 draw-in groove 5, simplify technique, practicality is stronger.
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.
