The specific embodiment
Describe with reference to the accompanying drawings illustrative of the present invention, non-limiting example in detail, heart Minimally Invasive Surgery shears according to the present invention is further described.
Heart Minimally Invasive Surgery shears hereinafter with reference to Fig. 1-4 explanation according to the embodiment of the present invention.Heart Minimally Invasive Surgery shears 1 according to the present invention comprises cutter head 2, slender casing 3, handle of a knife 4, handle 5 and pull bar 6.
Particularly, with reference to Fig. 1 and Fig. 4, slender casing 3 has relative first end 31 and the second end 32, and described sleeve pipe forms the cutter pipe of surgical scissors 1.Cutter head 2 is fixed to the first end 31 of sleeve pipe 3.The near-end 41 of handle of a knife 4 is connected to the second end 32 of sleeve pipe 3, and the part of the close sleeve pipe 3 of handle of a knife 4 is formed with through hole 42.Pull bar 6 is engaged in through hole 42 and sleeve pipe 3 movably.
In one embodiment of the invention, the first link gear comprises two first connecting rods 8, and first connecting rod has respectively first end and the second end.The first end of first connecting rod 8 is pivotably connected to respectively in blade 7 other end of corresponding, and the second end of first connecting rod 8 is pivotably connected to a described end 61 of pull bar 6.In the present invention, the first end of first connecting rod 8 and the second end are connected respectively to cutter head 2 and sleeve pipe 3 by pivot.Yet the connected mode of first connecting rod and cutter head and sleeve pipe is not limited to this, also can be pivotably connected to hinged or in other known methods cutter head and sleeve pipe.
The diameter that the second end 32 of sleeve pipe 3 can have ，Gai expansion section, expansion section alternatively is greater than the diameter of the main body of sleeve pipe 3.This expansion section is formed with groove 33.The near-end 41 of handle of a knife 4 has the shape corresponding with groove 33, and near-end 41 is connected in groove 33, thereby handle of a knife is connected to sleeve pipe.Because the second end of sleeve pipe has for connecting the expansion section of handle of a knife, therefore can be in the situation that guarantee the stable elongated sleeve pipe of acquisition that is connected of handle of a knife and sleeve pipe.In addition, the first end 31 of sleeve pipe 3 for example can be formed with recess 34, and the end be connected with the first link gear of cutter head is arranged in recess 34.
According to the present invention, the handle 5 of surgical scissors 1 consists of two arms, and described two arms extend to near-end 41 from the far-end 43 of handle of a knife 4.The end of two arms is connected to the other end 62 of pull bar 6 by the second link gear, and two arms are formed with grip part 51 at the part place near sleeve pipe 3 respectively.Referring to Fig. 4, grip part 51 preferably is formed with a plurality of cannelures 52, prevents during with the grasped handle at user that hands from sliding.
According to one embodiment of present invention, described the second link gear comprises two second connecting rods 9, and described second connecting rod has respectively first end and the second end.The first end of second connecting rod 9 is pivotably connected to respectively in two arms of handle 5 end of corresponding, and the second end of second connecting rod 9 is pivotably connected to the described other end 62 of pull bar 6.Alternatively, the first end of second connecting rod 9 and the second end are pivotably connected to handle arm and pull bar by pivot respectively.Yet the connected mode of the second link gear and handle and pull bar is not limited to this, also can be pivotably connected to hinged or in other known methods handle and pull bar.In addition, above-mentioned link gear is only to illustrate as example, and the structure of link gear is not limited to this.
In heart Minimally Invasive Surgery shears according to the present invention, the second end 32 of slender casing 3 preferably is provided with protuberance 35, and described protuberance is outwards outstanding from slender casing 3.As shown in Figure 4, protuberance 35 has air inlet 36, the internal communication of described air inlet and sleeve pipe 3, and so that clean air is sent in sleeve pipe, thus the stain that the dust in clean sleeve pipe and operation process enter.Clean air preferably adopts Compressed Gas, for example compression arbon dioxide, compressed inert, compressed nitrogen and similar Compressed Gas.Because the protuberance 35 with air inlet 36 is arranged on an end of the close handle of slender casing, therefore input the operation that can not have influence on surgical scissors in operation process that operates in of clean air by air inlet, and then can in operation, realize the cleaning fully to sleeve pipe.
Next the operation according to heart Minimally Invasive Surgery shears of the present invention with reference to Fig. 4-6 explanation.While carrying out shearing manipulation in need to the body at treatment target in operation on heart, user is similar to that pen holding posture is held the handle 5 of surgical scissors and grip part 51 places at handle 5 by forefinger and thumb press, handle of a knife 4 is near the intersection between forefinger and thumb, as shown in Figure 5.Like this, user is easy to control surgical scissors.
The operation of heart Minimally Invasive Surgery shears is described referring to Fig. 4 particularly.When handle 5 opens, the second link gear pushing drawing rod 6 moves right in through hole 42 and sleeve pipe 3, drives the outside pivotable of two first connecting rods 8 of the first link gear simultaneously, thereby two blades 7 are rotated and opens.On the contrary, when handle 5 is closed, by the second link gear pushing drawing rod 6, in through hole 42 and sleeve pipe 3, be moved to the left, drive the inside pivotable of two first connecting rods 8 of the first link gear simultaneously, thus two blades 7 are rotated and closure to complete shearing manipulation.In addition, because the second end 62 of pull bar 6 is accommodated in the through hole 42 of handle of a knife 4, therefore only need in-situ transesterification moving knife handle just can make the blade sensing different directions of blade, as shown in Fig. 6 b-6e.
Heart Minimally Invasive Surgery shears according to the present invention is the end application of force near the cutter pipe at handle, even also can operate accurately the shears cutter head in the situation that the cutter pipe is very long thus, thereby can be operated at darker operative site.Therefore, heart Minimally Invasive Surgery shears of the present invention can have very long length.For example, the cutter length of tube can be in the scope of 30-400mm.In addition, traditional surgical scissors volume is larger, and it is larger that two blades open scope.And surgical scissors of the present invention is realized opening of blade by the transmission campaign, make blade to open very littlely.For example, the scope of opening of blade is in the scope of 5-50mm.In addition, although above, be only that the surgical scissors to having the Curved cutter head describes (as shown in Figure 6 a), one skilled in the art will appreciate that the shape of cutter head is not limited to this, and can be flat shape, hook-like shape or other suitable shape.
Although some embodiment of total inventive concept of the present invention are shown and explanation, but those of ordinary skills will be understood that, in the situation that do not deviate from spirit of the present invention and principle can make a change these embodiment, scope of the present invention claims with and equivalent in limit.
