Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Fig. 3, chamber mirror holding forceps 2, comprise hollow claw beam 10, combination handle 11, two semicircle clamps 8 and pull bar 9, described combination handle 11 comprises fixed handle 12 and flexible handle 13, fixed handle 12 is fixed on one end of hollow claw beam 10, flexible handle 13 is hinged with fixed handle 12, pull bar 9 is through at the inside of hollow claw beam 10, one end of pull bar 9 is connected with flexible handle 13, the tail end of two semicircle clamps 8 be articulated be fixed on hollow claw beam 10 other end bearing pin 15 on, on described bearing pin 15, cover has torsion spring, semicircle clamp 8 is fixedly linked with two respectively at the two ends of torsion spring, the tail end of described semicircle clamp 8 intracavity be provided with to hollow claw beam 10 smoothly transits the bow 17 extended, the tip mirror of bow 17 is to being hinged with connecting rod 16, described connecting rod 16 is hinged with the other end of pull bar 9, the medial surface of two semicircle clamps 8 is vertically evenly equipped with some ratchets, operant activity handle 13, pull bar 9 drives two semicircle clamps 8 to open, and to close be an annulus, carry out clamping and decontroling action.
Extruding digestive tract wall can not occur after clamping digestive tract for making semicircle clamp 8 when closed, after also preventing clamping digestive tract, dropout phenomenon occurring simultaneously, the jaw joint of two semicircle clamps 8 is set to zigzag handing-over.
The internal diameter of described annulus is 8-24mm, and the length of described holding forceps 2 is 350-450mm.This holding forceps 2 is not only applicable in the mirror cerclage operation of chamber, and its internal diameter and length can suitably adjust.
Shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, a kind of cerclage bar 1 carrying out cerclage with above-mentioned holding forceps, described cerclage bar 1 is can loose formula band structure, comprise sour jujube bar 3, the end of sour jujube bar 3 is provided with snap close 4, and sour jujube bar 3 lateral surface is evenly equipped with the first ratchet 5, and described first ratchet 5 matches with the ratchet of semicircle clamp 8 medial surface, the medial surface of sour jujube bar 3 is provided with strip projected parts along its length, and described snap close 4 is provided with detent 6; Described cerclage bar 1 is medical macromolecular materials; The width of cerclage bar 1 is 2-5mm, and length is 80-90mm, and the width of cerclage bar 1 is less than the width of semicircle clamp 8.
In the mirror anastomosis operation of chamber, this holding forceps 2 and cerclage bar 1 with the use of, make simple and quick, cerclage is evenly compact, time saving and energy saving, safe can complete cerclage operation narrow space is convenient and swift, avoid the defect that in prior art, cerclage exists.The following detailed description of the structure of holding forceps 2 and cerclage bar 1 and with the use of process.
Cerclage bar 1 is hard polypropylene material, with use in prior art can loose formula band or selt-locking wrapping tape can the structure of loose formula and principle identical, can tighten and unclamp, unlike, this cerclage bar 1 is provided with ratchet outside it, inner ring surface has the strip bulge 7 identical with sour jujube bar 3 bearing of trend, when locking is annulus, ratchet is in the outside of annulus.Its structure is specifically formed primarily of sour jujube bar 3 and snap close 4, and sour jujube bar 3 length is 85mm, and be 5mm at sour jujube bar 3 width being provided with snap close 4 end, the width of sour jujube bar 3 remainder is 2mm; The outer surface of the sour jujube bar 3 of narrower one end is evenly distributed with the first ratchet 5, detent 6 is provided with in lockhole on snap close 4, when sour jujube bar 3 passes the lockhole on snap close 4, the first ratchet 5 is blocked by detent 6, make cerclage bar 1 become annularity, under this state, can be used for the cerclage operation in digestive tract site.The inner ring surface of sour jujube bar 3 there is the strip bulge 7 identical with sour jujube bar 3 bearing of trend, arrange and its objective is and make the cerclage bar 1 of annular carry out gastral cerclage site in ligation process comparatively large with the frictional force of digestive tract epidermis, there will not be the cerclage bar 1 of annular in cerclage process from the adverse consequences that cerclage site comes off.Holding forceps 2 is made up of two semicircle clamps 8, pull bar 9, hollow claw beam 10 and combination handles 11, and holding forceps 2 entire length is 350mm ~ 450mm.Combination handle 11 is provided with fixed handle 12, flexible handle 13 and is articulated with the first pin joint 14.Pull bar 9 is positioned at hollow claw beam 10, and its one end connects flexible handle 13, and the other end connects semicircle clamp 8, and moving back and forth therefore along with the relative fixed handle 12 of flexible handle 13, semicircle clamp 8 presents the alternating state of opening and closing.The diameter range of semicircle clamp 8 is 8mm ~ 24mm, the ratchet matched with the first ratchet 5 on cerclage bar 1 is had in the inner surface of semicircle clamp 8, what therefore cerclage bar 1 can be safe in the use of process is positioned in semicircle clamp 8, snap close 4 in cerclage bar 1 is in one end of semicircle clamp 8, and the other end is the sour jujube bar 3 that cerclage bar 1 throws away after semicircle clamp 8 one encloses.See Fig. 8, Fig. 9, when manipulation activities handle 13 makes pull bar 9 drive semicircle clamp 8 slowly to occur closed by open configuration, the sour jujube bar 3 of semicircle clamp 8 one end is slowly near the snap close 4 of semicircle clamp 8 opposite side, thus along with the closed sour jujube bar 3 of semicircle clamp 8 also tightens gradually through snap close 4, the contractile loop configuration of final formation, thus carries out ligation operation to needs Ligation.
Coincide for esophagus and stomach, first getting cerclage bar 1 and semicircle clamp 8 diameter is that the holding forceps 2 of 8mm ~ 10mm is assembled, for the capable ligation of the esophageal stump putting into nail seat.Clamp position under open configuration of the present utility model is enclosed within the esophageal stump periphery needing ligation, with the marginal position that operating forceps clamps esophageal stump, the position of esophageal stump and nail supporting base is put proper, handle flexible handle 13 of the present utility model afterwards, pull bar 9 is driven with flexible handle 13, under the elastic force of torsion spring, make the clamp of open configuration slowly close, in generation closing course, the sour jujube bar 3 that one end clamp throws away is slowly near the snap close 4 at other end clamp place, thus sour jujube bar 3 forms annular through snap close 4, along with clamp closes, cerclage bar 1 tightens gradually, finally form pocket state at esophageal stump.
In addition, holding forceps 2 can also separately as holding thing instrument, as in total surgical resection for clamping tumor; Simultaneously because the internal diameter of the semicircle clamp 8 of holding forceps 2 is 8-24mm, and the diameter of esophagus is probably about 2mm, and therefore holding forceps 2 also can for free esophagus in operation.
