Description

The turnover nail-anvil of disposable end-end anastomat
Technical field
This utility model belongs to a kind of surgical apparatus, is specifically related to a kind of disposable end-end anastomat.
Background technology
The present various end-application of end anastomat in surgical operation is more and more, and this appliances can shorten operating time, improves operation efficient.Digestive tract end-end anastomat is to be used for esophagus, stomach, and the pipeline broken ends of fractured bone and the broken ends of fractured bone in the surgical operations such as intestinal, lumen organizations such as the pipeline broken ends of fractured bone and cavity side fracture coincide.Its primary structure is (referring to Fig. 1): device body head is equipped with nail casket (8), the ring-type nail bin and the nail pushing device of dress titanium seam nail in the nail casket is provided with, ring-type nail bin internal ring side is equipped with endless knife (10), described nail pushing device and endless knife and propeller (11) are in transmission connection, propeller is in transmission connection by the firing handle (17) of trigger shaft (15) with afterbody, this device also is provided with the anvil pull rod (14) that can advance and retreat under empennage turn-knob (18) control, device body front portion is provided with and can follows closely the hat nail anvil (A) of anvil pull rod (14) socket connection in casket (8) centre bore by center connecting rod (7) and ring-type;
The using method of this utensil is: both sides broken ends of fractured bone tissue that will be the to be coincide during operation pocket of sewing it up, anastomat device body is inserted from a side pipe chamber, the pocket of this side-to-side anastomosis port is tightened up in anvil pull rod (14), (A) imbeds the opposite side tube chamber with the hat nail anvil, and the pocket of this side-to-side anastomosis end tightened up in hat nail anvil (A) center connecting rod (7), center connecting rod (7) with the hat nail anvil inserts anvil pull rod (14) again, regulate empennage turn-knob (18), making anvil pull rod (14) drive hat nail anvil (A) retreats, until hat nail anvil (A) near the nail casket (8) of device body head and clamp the pocket shape tissue of both sides, when the tissue thickness that clamps arrives safety percussion interval, depress firing handle (17), to follow closely the interior titanium seam nail release of casket with the nail pushing device (11) that firing device is in transmission connection, the tissue that passes both sides arrives nail anvil (A), under the guiding of the cutter anvil (5) on the nail anvil, be the B font, kiss is sewed up by the lumen organization of both sides to be connect, release the unnecessary tissue at endless knife (10) excision center, annular suture site simultaneously, the both sides tube chamber is communicated with, extract anastomat from body lumen together with nail anvil (A) at last, operation is finished.
The hat nail anvil (A) of the surgery end-end anastomat that uses clinically all is to be 90 degree with center connecting rod (7) to fixedly connected at present, behind the end of operation, in the process of drawing back with the hat nail anvil (A) of anastomat anvil pull rod (14) socket connection, pass the annular anastomotic position of stitching, though the tissue of sewing up has certain elasticity, but in the process that the hat nail anvil is extracted, still may cause the anastomotic stoma torn tissue.Someone once designed the nail anvil of band turn over function, but because of existing manufacturability not good enough and stable bad in actual applications, so rare on the market this series products.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of nail anvil and can overturn, and the turnover nail-anvil of the disposable end of stable and reliable operation-end anastomat, this anastomat nail anvil can overturn after tissue apposition kiss in both sides connects, thereby can avoid the torn tissue of anastomotic position when extracting as far as possible.
The technical scheme that addresses the above problem is (referring to implementing illustration): this utility model is provided with nail casket (8) at the anastomat front end, nail anvil (A), described nail anvil (A) is provided with center connecting rod (7), medicated cap body (4), medicated cap body rear end face is provided with endless knife anvil (5), it is characterized in that: described center connecting rod (7) is hinged with the connector (12) on the medicated cap body rear end face by ship and resell on another market (1), the centre bore of supporting disk (6) is passed in center connecting rod (7) lower end, and be stuck in the centre bore edge by the step on the sidewall, supporting disk (6) is supported on the supporting spring (3), supporting spring (3) edge rides over back cut diameter on the medicated cap body (4) less than on the cavity (13) of intracavity diameter suitable for reading, turnover spring (2) inner end elastic top is on center connecting rod (7) is positioned at sidewall between rotational pin (1) and the lower end, the outer end is connected with the supporting disk outer rim, and the annular propeller (11) of described nail casket (8) is provided with the annular ennation (11a) forward facing to nail anvil supporting disk (6).
Operation principle of the present utility model is: generally, center connecting rod (7) lower end that supporting disk (6) centre bore edge pins and the medicated cap body is hinged makes it can not rotate (referring to Fig. 4), and center connecting rod and medicated cap body rear end face keep plumbness; It is fashionable to kiss seam, with the center connecting rod (7) of nail anvil (A) and anvil pull rod (14) socket connection of nail casket (8) one sides, and by rotating the distance between anastomat empennage turn-knob (18) adjusting nail anvil (A) and the nail casket (8), until drawing close mutually, hold the firing handle (17) of anastomat afterbody then, give propeller (11) one impulsive forces by trigger shaft (15), Titanium nail in the nail casket nail bin is hit to the cutter anvil (5) of nail anvil, with the tissue apposition of both sides together, endless knife and angle of rake annular ennation (11a) stretch out from nail casket front end simultaneously, endless knife is excised the unnecessary tissue at center, annular suture site, the both sides tube chamber is communicated with, referring to Fig. 5, angle of rake annular ennation (11a) then acts on supporting disk (6) and promotes supporting spring (3), supporting spring (3) extruding is advanced in the cavity (13) of anvil medicated cap, because it is big in cavity (13) is young, so supporting spring (3) promptly can not come out after being got in the cavity, the supporting disk bottom has lost the support of supporting spring, also move to cavity (13) direction, originally blocking the centre bore margin and center connecting rod of center connecting rod (7) lower end step throws off, under the active force of turnover spring (2), the trend that nail-anvil cap body (4) has relative center connecting rod (7) to rotate, but because at this moment endless knife is just propping up the cutter anvil, and prop up the elastic force of the power of cutter anvil much larger than turnover spring, so medicated cap body (4) can not overturn before identical finishing.After the kiss seam was closed and finished, propeller, endless knife were all withdrawn in nail casket (8) head, and this moment, supporting disk (6) centre bore discharged connecting rod lower end, center, and the nail-anvil cap body begins under the effect of spring force relatively that the center connecting rod overturns.Coincideing when just having finished, because nail anvil (A) is still keeping identical spacing with nail casket (8), be full of by identical tissue between nail anvil and nail casket, and the power of turnover spring (2) to be less, the medicated cap body does not almost deflect.Along with nail anvil (A) after identical the finishing stretches out nail casket (8) gradually, nail anvil also strengthens gradually with the spacing of nail casket, the flip angle of nail-anvil cap body also strengthens gradually, and after nail anvil (A) outreach surpassed nail-anvil cap body radius, flip angle had reached maximum angle (referring to Fig. 6).Extract whole anastomat out this moment again together with nail anvil (A), because upset has taken place nail anvil (A), so can pass through the less anastomotic stoma of relative diameter smoothly.
This utility model can effectively be avoided sewing up tearing of kiss interface portion bit organization, and the reliable working performance of nail anvil upset is stable.
