The specific embodiment
Below in conjunction with Figure of description the present invention is done following detailed description.
Embodiment one, as shown in Figure 1, esophageal stump girdling device comprises arc clamping head 1, clamping limb 4 and the handle 11 that links to each other with clamping limb 4; On clamping head 1, be provided with arcuate cutting blade sheet 3, have groove 21 at the middle part of said clamping head 1, said cutting blade 3 is arranged in groove 21; Purpose is to prevent its hetero-organization of cutting blade damage patient; The width of its clamping head 1 is about 1cm, can be designed to when clamping head 1 closure its two cross-shaped attitudes of free end; In order to prevent that clamping head 1 occurs skidding with esophagus when cutting, can be provided with non-slip process 2 or anti-skidding stricture of vagina at the inner surface of clamping head 1.
The radian of its cutting blade 3 equals or is slightly larger than the circular arc of nail supporting base hollow stem, and so cutting blade 3 then can fully contact with the nail supporting base hollow stem in closure, reaches maximum facet; Can be being designed to cutting blade 3 in closure, its two cross-shaped attitudes of free end when cutting blade is done circular arc and moved, can not withstood esophageal wall because of the free end of cutting blade 3 and cause cutting fully like this.
On cutting blade 3, be provided with operating mechanism, its cutting blade 3 as shown in Figure 3 is connected with double buckle 14 with operating mechanism, also can connect through slot, perhaps other movable connection methods.
Its operating mechanism is made up of U-shaped arm 6, pull bar 8, bracing frame and operating grip 9, and its U-shaped arm 6 is to have steel disc to process, and has certain elasticity; Can restore to the original state automatically, be provided with through hole, be respectively equipped with connecting rod 5 at the two ends of U-shaped arm 6 at the middle part of U-shaped arm 6; Said connecting rod 5 is hinged with the two ends of U-shaped arm 6; The other end of said connecting rod 5 and pull bar 8 are hinged, and said pull bar 8 passes through hole and links to each other with operating grip 9 screw threads, and operating grip 9 is an adjusting nut; Support frame as described above is made up of two support bars that are hinged 7, and its said two support bar 7 hinged places and said pull bar 8 are movably connected, and purpose is to hold operating grip 9 can come back rotation; Come back rotation to drive cutting blade 3; Reach the purpose of cutting esophagus fully, be slidingly connected at the end and the clamping limb 4 of said support bar 7, its syndeton is the chute 19 that on clamping limb 4, is provided with as shown in Figure 4; Be provided with slide block 18 in the end of support bar 7, said slide block 18 is embedded into 19 li of chutes.The two ends of said U-shaped arm 6 are connected through double buckle 14 or slot with said cutting blade 3 respectively.
As shown in Figure 6; Be provided with catching groove 22 in the rear end of pull bar 8; On clamping limb 4, be movably equipped with locating rod 10, said locating rod 10 matches with catching groove 22, and its effect is to be two one lines with the pin joint that is movably connected in the support bar 7 on the pull bar 8; Limited the random rotation of operating mechanism before cutting, what help operating normally carries out.
As shown in Figure 5; Outer surface at clamping head 1 is provided with axial wire casing 20, and purpose is to make purse wire pass wire casing 20 to pull out, and so can limit the position of clamping head; In order to avoid purse wire is too much cut off in clamping or clip position is far away excessively from purse wire, esophageal stump can not be cut fully.
As shown in Figure 1, between said handle 11, be provided with buckle 12, purpose is the clamp position of fixed clamp 1.
Its work process is: during use, in esophageal lumen, put into nail supporting base, behind the ligation pocket suture, clamp with clamping head of the present invention and to wait to cut the esophagus place; Let two free ends of purse wire pass through the wire casing 20 on the clamping head respectively, the turn adjusting nut is when adjusting nut withstands U-shaped arm 6; Continue turn, connecting rod 5 beginnings are closed gradually, and the two ends that spur U-shaped arm 6 simultaneously are closed gradually; So drive cutting blade 3 closures, when cutting blade 3 touches the nail supporting base hollow stem, take out the locating rod 10 that matches with catching groove 22; Hold operating grip 9 and rotate back and forth, make cutting blade 3 do circular arc along the nail supporting base hollow stem and move, esophagus promptly is cut off.
