In Wicresoft's coronary artery bypass surgery, need in thoracic cavity, left side, cut the little otch of a 5-8cm, by retracting a upper root bone, expose internal mammary artery, under the assisting of thoracoscope, complete the separation of internal mammary artery.Therefore, a side of operative incision is rib, and opposite side is soft tissue.According to Wicresoft of the present utility model internal mammary artery retractor, comprise support and retractor main body, support is detachably connected to operation table by the first securing member, and in operation process across operation table be arranged on operation table above, retractor main body is detachably connected to support.Therefore, the upper root bone that this Wicresoft's internal mammary artery retractor can retract internal mammary artery exposes internal mammary artery, thereby completes the separation of internal mammary artery.
Describe with reference to the accompanying drawings illustrative of the present utility model, non-limiting example in detail, to being further described according to Wicresoft of the present utility model internal mammary artery retractor.
Particularly, Fig. 1 has schematically shown according to the structure of Wicresoft of the present utility model internal mammary artery retractor.Described retractor comprises the support 1 and the retractor main body 2 that is detachably connected to support 1 that is detachably connected to operation table by the first securing member.
According to an embodiment, the first securing member comprises that 3, two fixation clamps of two fixation clamps are connected respectively to the corresponding one end in the two ends of support 1.With reference to Fig. 2, each in two fixation clamps comprises a clamping part 31, fastening screw 32 and from the outstanding protuberance 33 of bed clamping part 31.Bed clamping part 31 has relative two bed grabs 331 and 332, and so that the edge clamping of operation table is held between two bed grabs, and a bed grab 331 is formed with female thread.One end of fastening screw 32 is provided with handle 321.Protuberance 33 is formed with rack ventilating hole 331 along the direction that is parallel to a clamping part 31, and the end of protuberance 33 is formed with female thread.Support screw 4 has external screw thread, and the externally threaded one end that do not have of support screw 4 is provided with swing handle 41.
When the separated internal mammary artery of needs Wicresoft, first the externally threaded end of having of support screw 4 is inserted in the female thread of protuberance 33, then rotate swing handle 41 so that the external screw thread of support screw 4 engages with the female thread of protuberance 33, and continue rotation swing handle 41 to be screwed into support screw 4, until support screw contacts support and support is fastened on fixation clamp.Then, two fixation clamps 3 are placed on respectively to the both sides of operation table, bed clamping part 31 is held in the edge clamping of bed between a grab 331 and 332.Then, the externally threaded end of being formed with of fastening screw 32 is inserted in the female thread of bed grab 331, the handle of rotation fastening screw 32 so that the external screw thread of fastening screw 32 engage with the female thread of bed grab 331, and be rotated further this handle to be screwed into fastening screw 32, until fastening screw contact bed edge is also clamped in an edge securely, thereby support 1 is fixed on operation table.
Next, describe the structure of retractor main body with reference to Fig. 3-6 in detail, retractor main body 2 comprises pedestal 21, draw-bar seat 22 and pull bar 23.Pedestal 21 is detachably connected to support 1 by the second securing member.Draw-bar seat 22 is arranged on pedestal 21 rotationally, and is formed with draw-bar seat through hole 221 along the direction that is parallel to pedestal 21.Pull bar 23 extends through draw-bar seat through hole 221, and one end of pull bar 23 is provided with drag hook 231.As shown in Figure 3, drag hook 231 has shape, but the shape of drag hook is not limited to this, and can adopt as required pawl type drag hook, with tooth drag hook, refer to the drag hook of any suitable shapes such as type drag hook.
Draw-bar seat 22 has recess 222, and this recess is connected with draw-bar seat through hole 221.Referring to Fig. 5, cylindrical part 212 inserts in recess 222, and pull bar 23 is positioned on cylindrical part 212.Cylindrical part 212 is formed with cannelure 2120, and draw-bar seat 22 has recess 223 in the position corresponding with cannelure 2120, and this recess is connected with cannelure 2120.Fix parts 6 and insert in cannelures 2120 and recess 223, make draw-bar seat 22 be connected to pedestal 23 and can be separated.For example, fixing firmware 6 can be pin (as shown in Figure 6), but fix firmware, is not limited to this.Because the cylindrical part of pedestal 23 is formed with cannelure and this cannelure is connected with the recess of draw-bar seat 22, after fixing parts 6 insert cannelure 2120 and recess 223 simultaneously, draw-bar seat 22 can be not separated with pedestal 23, but draw-bar seat 22 can rotate with respect to pedestal 23, thereby can regulate according to the action need in operation process the position of drag hook.
Further, in one embodiment, draw-bar seat 22 is formed with gear through hole 224 in a side of draw-bar seat through hole 221 along the direction perpendicular to pedestal 21, and this gear through hole is communicated with draw-bar seat through hole 221.According to retractor of the present utility model, also comprise rotary part 7, this rotary part comprises the gear part 71 of inserting in gear through hole 224 and the gear swing handle 72 that is positioned at gear through hole outside.Pull bar 23 is formed with ridge.With reference to Fig. 4 and Fig. 6, gear through hole 224 is communicated with draw-bar seat through hole 221, makes when rotary part 7 inserts in gear through hole 224 the ridge engagement of the gear of gear part 71 and pull bar 23.When operator rotates rotary part 7, gear driven pull bar 23 moves in draw-bar seat through hole 221, thus the length that adjusting yoke stretches out from draw-bar seat.Preferably, according to retractor of the present utility model, be also provided with ratchet 8.Ratchet 8 is hinged to draw-bar seat 22, and for example, ratchet 8 is hinged to draw-bar seat 22 by bearing pin 81.The end of ratchet 8 is connected in the ridge of pull bar 23, thereby makes the pull bar 23 only can single-way moving in draw-bar seat through hole 221.Fig. 4 has exemplarily shown ratchet, and wherein two ratchets 81 are hinged to draw-bar seat 22 in the both sides of pull bar 23 respectively.At this, be only in order to illustrate, exemplarily to show that ratchet, the quantity of ratchet are not limited to two, also can only arrange a ratchet.
Fig. 7 has shown according to the duty of Wicresoft of the present utility model internal mammary artery retractor.In operation on heart, support 1 is fastened on operation table by two fixation clamps 3, makes support 1 be placed on patient top across operation table, and retractor main body 2 is connected on support 1.Retractor main body 2 can be chosen in the installation site on support according to operative site, and the handle 51 by rotating basis screw rod 5 fixes retractor main body when retractor main body is placed on to appropriate location.Because draw-bar seat 22 is arranged on pedestal 21 rotationally, therefore can regulate by rotating tension bar seat direction and the position of drag hook.In addition, the gear of the ridge of pull bar 23, rotary part 7 and ratchet 8 form link gear, make to make pull bar 23 single-way movings by swing pinion swing handle 72, thus the length that adjusting yoke stretches out from draw-bar seat.Therefore, according to Wicresoft of the present utility model internal mammary artery retractor, can regulate according to the operation in operation position the mobile drag hook of drag hook, retract the separated internal mammary artery of a upper root Gu Yi Wicresoft of internal mammary artery, thereby carry out Wicresoft's coronary artery bypass surgery.
Although some embodiment of total inventive concept of the present utility model are shown and explanation, but those of ordinary skills will be understood that, in the situation that not deviating from spirit of the present utility model and principle, can make a change these embodiment, scope of the present utility model claims with and equivalent in limit.
