Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of damping and amortization anastomat.
Background technology
Linear type suturing instrument/anastomat is a kind of surgical operation attachment means of commonly using, is usually used in closed digestive tract and viscera tissue wound.Generally comprise housing, be fixed on two nail supporting base clamping plate in housing, be arranged at nail supporting base clamping plate far-end and for implement sew application nail anvil and nail bin, be arranged in nail supporting base clamping plate for promoting the actuating device of the nail in nail bin and nail bin, and be arranged on nail supporting base clamping plate and be connected in spacing handle and the ejector pin handle of actuating device by a rotating shaft pivot.Described actuating device comprises and is arranged at two nail supporting base clamping plate inner sides for two nail bin push pedals promoting nail bin and move to nail anvil direction along nail supporting base clamping plate and is arranged between two nail bin push pedals and for promoting the nail pushing plate of nail.
The use of this apparatus is roughly as follows: first, nail anvil is separated with nail bin, make stiching instrument in original state, tissue to be sewed up is placed between nail anvil and nail bin; Then, push spacing handle, by the effect of nail bin push pedal, nail bin is drawn close to nail anvil direction, apparatus, now in semi-closed state, can do further and adjust the position of tissue; Then, continue the spacing handle of extruding, nail bin is drawn close and compressed tissue to nail anvil further, apparatus is now in closure state; Extruding ejector pin handle, releases the nail in nail bin by the effect of nail pushing plate, thereby completes sew application; Finally, press SR, nail bin push pedal, nail pushing plate and nail bin return to original state together.
And existing Linear type suturing instrument/anastomat, in playback process after closure completes, apparatus playback is impacted very large, and apparatus vibrations obviously and have a larger noise, and easily make the suturing nail in nail bin drop in patient body, cleaning and stitching are produced to very serious impact.
Summary of the invention
This utility model will solve the problems of the technologies described above, vibrations and noise while providing one effectively to alleviate apparatus return, and safe damping and amortization anastomat.
The scheme that this utility model technical solution problem adopts:
A kind of damping and amortization anastomat, comprise: housing, be fixed on two nail supporting base clamping plate in housing, be arranged at nail supporting base clamping plate far-end and for implementing nail anvil and the nail bin of sew application, be arranged at two nail supporting base clamping plate inner sides for two nail bin push pedals promoting nail bin and move to nail anvil direction along nail supporting base clamping plate and be arranged between two nail bin push pedals and for promoting the nail pushing plate of nail, between nail pushing plate and nail bin push pedal, be provided with assembly clamping plate, be arranged on nail supporting base clamping plate by rotating shaft pivot, and be connected in spacing handle and the ejector pin hands handle of nail bin push pedal and nail pushing plate, in described nail pushing plate and/or nail bin push pedal, be provided with air cushion.
Further, organizing on clamping plate of described nail pushing plate and nail pushing plate both sides is provided with guide groove, and air cushion is fixed in guide groove, in order to being fixedly connected with nail pushing plate, organize the export trade of clamping plate and nail bin push pedal, in the time that apparatus opens, air cushion and outer pin contacts, when apparatus is closed, air cushion and export trade depart from.
Further, described air cushion is front end sealing, and foraminate air bag is established in rear end.
The beneficial effects of the utility model are, in nail pushing plate and/or nail bin push pedal, be provided with air cushion structure apparatus playback generation has been shaken to cushioning effect, effectively reduce apparatus vibrations and noise, avoid vibrations the impact of staple in nail bin to be improved to the safety of instrumentation.

Fig. 4 is air cushion structure schematic diagram of the present utility model;
In figure, 1 nail anvil, 2 nail bins, 3 air cushions, 4 export trades, 5 shells, 6 spacing handles, 7 ejector pin handles, 8 nail pushing plates, 9 assembly clamping plate, 10 nail bin push pedals, 11 nail supporting base clamping plate, 12 guide grooves.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further, but this utility model is not limited to embodiment.
A kind of damping and amortization anastomat, comprise housing 5, be fixed on two nail supporting base clamping plate 11 in housing 5, be arranged at nail supporting base clamping plate 11 far-ends and for implementing nail anvil 1 and the nail bin 2 of sew application, be arranged at two nail supporting base clamping plate 11 inner sides for two nail bin push pedals 10 promoting nail bin 2 and move to nail anvil 1 direction along nail supporting base clamping plate 11 and be arranged between two nail bin push pedals 10 and for promoting the nail pushing plate 8 of nail, between nail pushing plate 8 and nail bin push pedal 10, be provided with assembly clamping plate 9, be arranged on nail supporting base clamping plate 11 by rotating shaft pivot, and be connected in spacing handle 6 and the ejector pin handle 7 of nail bin push pedal 10 and nail pushing plate 8, in described nail pushing plate and/or nail bin push pedal, be provided with air cushion 3.In the present embodiment, organizing of described nail pushing plate 8 and nail pushing plate both sides is provided with guide groove 12 on clamping plate 9, air cushion 3 is fixed in guide groove 12, in order to being fixedly connected with nail pushing plate 8, organize the export trade 4 of clamping plate 9 and nail bin push pedal 10, in the time that apparatus opens (with reference to figure 1), air cushion 3 contacts with export trade 4, and when apparatus is closed, (with reference to figure 2) air cushion 3 departs from export trade 4.A kind of preferred air cushion structure of this utility model, as shown in Figure 4, air cushion is front end sealing, foraminate air bag is established in rear end, when apparatus opens, this air bag and outer pin contacts, air bag is under external force squeezing action, and venting compression, produces cushion effect to apparatus; Apparatus closure, air bag and export trade depart from, air bag under caoutchouc elasticity effect, air-breathing diastole; When apparatus resets, export trade has squeezing action to air bag, when inside air bag gas extrusion is gone out, can produce resistance to apparatus, slows down apparatus resume speed, reduces the vibrations of apparatus because of reset generation.
Those skilled in the art, according to design of the present utility model, can change and numerous embodiments.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, within all dropping on the claimed scope of this utility model.
