Embodiment 1
The present embodiment provides a kind of enteric cavity staplers of modified form, as shown in Figure 1-3, the enteric cavity stapler includes by outer
To interior outer barrel 1, the first inner cylinder 2, the second inner cylinder 3 and the pull rod 4 for being sequentially coaxially arranged and being bonded to each other, it is set to pull rod
The top 5 of 4 upper ends and concordant profipole 7；The top 5 includes elastic base 51, the elastic covering being located on the elastic base 51
51 top of elastic base is protruded on body 52 and the clamping ring 53 for being connected to 52 middle part inner circumferential of flexible housing, 4 top of the pull rod
And it is connected by pitman 54 with the clamping ring 53；The concordant profipole 7 is connected on toroid 71 including toroid 71, interval
More short-terms 72 and the high hydroscopic resin ball 73 that is connected on 72 free end of short-term, the outer barrel 1 and the first inner cylinder 2 it
Between and the first inner cylinder 2 and the second inner cylinder 3 between along it is axial can relative misalignment, with outer barrel 1 and the second inner cylinder 3 it
Between form the space for be placed in concordant profipole 7 after frost, offer on the elastic base 51 for pass through the short-term 72 freezed,
Multiple apertures 511 of high hydroscopic resin ball 73 and water.The enteric cavity stapler can also include ice making mold 8, the ice making mould
Tool 8 include for be put into the annular groove 81 of toroid 71 and water, be connected to 81 lower end of annular groove for being put into short-term 72, high inhaling
Multiple strip grooves 82 of water-resin ball 73 and water, the internal diameter of the annular groove 81 is greater than the internal diameter of second inner cylinder 3, described
The outer diameter of annular groove 81 is less than the internal diameter of outer barrel 1.
The usage mode of the present embodiment enteric cavity stapler is as follows: first by the short-term 72 of concordant profipole 7 as shown in Figure 2 and high suction
Water-resin ball 73 is put into the strip groove 82 of ice making mold 8, then toroid 71 is put into annular groove 72, then by ice making mould
Tool, which is put into refrigerator-freezer, to be rapidly frozen, and high hydroscopic resin ball is quickly cooled down, and is then injected water into ice making mold, needless to say water suction tree
Rouge water swelling, then ice making mold, which is put into refrigerator-freezer, makes water therein quickly freeze.Then attached in one section of enteric cavity cut-off part
Strip opening is opened up in close, and outer barrel 1 as shown in Figure 1, top 5 are protruded into enteric cavity and passed through from strip opening and cut
Disconnected place simultaneously enters top 5 in another section of enteric cavity, then pulls open outer barrel 1 and top 5, and makes the first inner cylinder 2 and outer barrel 1
It is staggered with the second inner cylinder 3, makes the gap for forming concordant profipole 7 after receiving freezes between outer barrel 1 and the second inner cylinder 3, then
According to shown in Fig. 4,100 connecting place of two-section enteric cavity is inwardly folded and is filled between top 5 and outer barrel 1, then pull downward on
Handle 6 makes pull rod 4 that will turn up grips, the short-term 72 and high water absorption of concordant profipole 7 after then pushing the first inner cylinder 2 to make frost
Pelletized resin ball 73 pass rapidly through turns up part and enter elastic base 51 aperture 511 in, then pull downward on handle 6, make with
Pull rod 4 connected pitman 54, clamping ring 53 and flexible housing 52 are shunk inwardly downward, and make at the same time elastic base 51 to
Interior upward contraction makes to be broken in the icicle of 72 periphery of short-term, and short-term and high hydroscopic resin ball is prevented to be pulled.As body temperature is by ice
The thawing of concordant profipole 7 after jelly, and high water absorption pelletized resin ball 73 in elastic base 51 quickly water suction swell, at this time as shown in Figure 1,
The part side of turning up of two sections of enteric cavities 100 is fixed by toroid 71, and the other side is consolidated by the high water absorption pelletized resin 73 to swell that absorbs water
It is fixed, and the place of turning up for the extruding enteric cavity 100 of high water absorption pelletized resin ball 73 to swell that absorbs water is completely embedded two sections of enteric cavities 100, then
Suture strip opening.And when two sections of enteric cavities 100 were connected at 7-15 days or so, patient restores feed, passes through enteral stream
The collision of dynamic food, hits down high water absorption pelletized resin ball 73 and excretes out, and short-term 72 and toroid 71 also can be in enteric cavities
Automatic-falling.
When the enteric cavity stapler of the embodiment of the present invention carries out enteric cavity and coincide, can using in freezing state toroid,
Short-term and high hydroscopic resin ball carry out the annular enteron aisle notch that coincide, and improve suture efficiency, and material residual of coincideing in vivo
Less and it is easy to be discharged, reduces the generation of postoperative complications.
Embodiment 2
It is starch grafted acrylate polymerization the present embodiment provides high hydroscopic resin ball, such as the high hydroscopic resin ball 73
Cross-linking agent or acrylamide and acrylic acid salt crosslinking copolymerization object, above two cross-linking agent have absorption speed is fast, Water absorption is high,
Intensity is high and the characteristics of being not easily decomposed.
Embodiment 3
The present embodiment provides strip groove and toroid, the end of the strip groove 82 is set as tip, to make strip groove
Generated icicle has tip in 82, easily propagates through the place that turns up of enteric cavity, is arranged at intervals with 10-12 root on the toroid 71
Short-term 72, to improve the fastness of the enteric cavity place of turning up connection.
Embodiment 4
The present embodiment provides material, described is elastic base 51 and flexible housing 52 is acrylic resin, to make elasticity
Pedestal 51 and flexible housing 52 have certain elasticity and rigidity.The clamping ring 53 and pitman 54 are steel wire, to make to connect
Adapter ring 53 and pitman 54 also have certain elasticity and rigidity, improve elastic base, flexible housing, clamping ring and pitman
Ease of use.
Embodiment 5
The present embodiment provides high hydroscopic resin ball size, the size of the high hydroscopic resin ball 73 is 0.1-0.8mm, water suction
The size of high hydroscopic resin ball 73 afterwards is 5-10mm, so that so that high hydroscopic resin ball 73 is passed through enteric cavity turns up place, and is inhaled
High hydroscopic resin ball 73 after water, which is capable of fixing, turns up the place other side in enteric cavity, so that identical enteric cavity is just played, it is convenient and efficient.
In addition, the tranexamic acid for hemostasis can be contained in the short-term 72 of the frost, high hydroscopic resin ball 73 and water,
To be conducive to stop blooding, tranexamic acid easily holds in water, can be properly added.
When the enteric cavity stapler of the embodiment of the present invention carries out enteric cavity and coincide, can using in freezing state toroid,
Short-term and high hydroscopic resin ball carry out the annular enteron aisle notch that coincide, and improve suture efficiency, and material residual of coincideing in vivo
Less and it is easy to be discharged, reduces the generation of postoperative complications.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
