The adjustable angle of formation.The lower end of first sleeve 61 is threadedly coupled with bolt 7.Wherein, bolt 7 is screwed under the first sleeve 61
End, the end face (lower face of the first mounting rod 1 i.e. shown in Fig. 3) of one end for being tightened in cylindrical bar, thus by rack
Plate 6 is fixed on the lower end of the first mounting rod 1.
In a second embodiment shown in figure 2, it is main regarding the multi-functional retractor of bypass operation of coronary artery to be used for micro-wound direct
Breastbone struts when anastomotic position for bridge-target vessel appears, including the first mounting rod 1, the second mounting rod 2, first push
Part 3, the second pressing member 4 and rack-plate 6.
Second pressing member 4 coordinates with the first pressing member 3 pushes the breastbone of patient both sides open, is used for the kiss of bridge-target vessel
Position is closed to reveal.At this point, the first pressing member 3 on the first mounting rod 1 is used to push open on the breastbone of patient side,
The second pressing member 4 on the second mounting rod 2 is for pushing the breastbone of the patient other side open.And second pressing member 4 with can
The mode of dismounting is mounted on the second mounting rod 2, so that the second pressing member 4 can be disassembled from the second mounting rod 2.
Wherein, part 5 or the installation of the second pressing member 4 are triggered to the second mounting rod 2.That is, the second pressing member 4 and triggering
One of both parts 5 are selectively mounted to the second mounting rod 2.Specifically, when the multi-functional retractor of the utility model is used
When small notch internal mammary artery shown in FIG. 1 obtains when the traction of the wall of the chest, the first pressing member 3 is installed to the first mounting rod 1, and
The installation of part 5 will be triggered to the second mounting rod；When the multi-functional retractor of the utility model is for bridge-target vessel shown in Fig. 2
When strutting of breastbone when anastomotic position appears will be triggered part 5 and be disassembled from the second mounting rod 2, the second pressing member 4 is corresponded to
On the second mounting rod 2.To make the retractor of the utility model that can either retract the wall of the chest when obtaining internal mammary artery, show
Reveal surgical field of view, also breastbone can be retracted when bridge-target vessel coincide appears anastomotic position.
In a preferred embodiment, the first pressing member 3 is identical with the structure of the second pressing member 4, to effectively reduce zero
The use type of component, and effectively save cost, while the effect for making the first pressing member 3 be played with the second pressing member 4 is consistent.
That is, the first pressing member 3 and the second pressing member 4 are in shape, size, material etc. all same.
In a preferred embodiment, the second mounting rod 2 is mounted in such a way that position is adjustable on rack-plate 6, so that
Spacing between second mounting rod 2 and the first mounting rod 1 can be adjusted, to make be mounted on the first mounting rod 1 the
One pressing member 3 and the second pressing member 4 on the second mounting rod 2 or the spacing triggered between part 5 can be adjusted, into
And according to it is actual appear needs and adjust strut and strut distance between both sides breastbone or the both sides wall of the chest.
Referring specifically to Fig. 1, one end (lower end i.e. shown in FIG. 1) of the second mounting rod 2 is provided with cartridge 21, and cartridge 21 can
It is set in the outside of rack 62.Specifically, it is provided in cartridge 21 for being extended upward through for the right and left shown in Fig. 1 of rack 62
Through hole or opening, and the width on through hole or open front-rear direction shown in Fig. 1 is set as only allowing 62 edge of rack
It is moved on left and right directions shown in FIG. 1, the height on through hole or open upper and lower directions shown in Fig. 1 is set greater than
Width of the rack 62 in upper and lower directions shown in Fig. 1.
The rotating handle 22 that can be rotated in the plane where being parallel to cartridge 21 relative to cartridge 21 is provided in cartridge 21.
By the rotation of rotating handle 22 cartridge 21 to be fixed on rack 62, to which the second mounting rod 2 is fixed on rack-plate 6.Or
Cartridge 21 is set to be slided along rack 62 by the rotation of rotating handle 22, between adjusting between the second mounting rod 2 and the first mounting rod 1
Away from.
Referring specifically to Fig. 1, fig. 4 to fig. 6, rotating handle 22 includes mesh piece 221 and handle 222.Mesh piece 221 runs through cartridge 21
On through-hole 211, and mesh piece 221 can be meshed with rack 62.Plane where handle 222 is parallel to 21 place of cartridge
Plane, handle 222 are connect with mesh piece 221, and can drive mesh piece 221 relative to cartridge 21 in fixed position and sliding position
It is rotated between setting.Specifically, mesh piece 221 runs through in cartridge 21 from shown in FIG. 1 on paper direction from the bottom to top
Through-hole 211, and the diameter of section positioned at invisible end of mesh piece 221 is more than the diameter of through-hole 211.Protrusion on handle 222
2221 pass through the through-hole being arranged in the visible ends of mesh piece 221, and are fixed by the bolt or nut with 2221 cooperation of protrusion
On handle 222.
Wherein, one of in the fixed position, two cylinders of the center of mesh piece 221 with 62 phase of rack
Engagement, cartridge 21 is fixed on rack 62；In the sliding position, two cylinders and tooth of the center of mesh piece 221
Item 62 is separated, and cartridge 21 is made to be slided along rack 62.It should be pointed out that two cylinder settings are point-blank, and two
Air line distance between cylinder is less than the width of the tooth of a protrusion of rack 62, to prevent in the sliding position, rack 62
In the tooth of protrusion be stuck between two cylinders.
For example, when anastomotic position of the multi-functional retractor of the utility model for bridge-target vessel shown in Fig. 2 appears
When strutting of breastbone, rotating handles 222 make cartridge 21 be slided along rack 62 to drive mesh piece 221 to turn to sliding position, with
Adjust the spacing between the second mounting rod 2 and the first mounting rod 1.The first pressing member and the second pressing member is set to coordinate the chest of both sides
Bone level is pushed open to suitable distance.At this point, the rotation of rack 62 is pushed away breastbone level with guarantee to the position parallel with sternal plane
It opens.
In the multi-functional retractor for regarding bypass operation of coronary artery for micro-wound direct of the utility model, for patient one
The first pressing member that the wall of the chest of side is pushed is mounted on the first mounting rod, the hook for triggering the wall of the chest of the patient other side
Part is played to be removably mounted on the second mounting rod.To make to trigger part and the cooperation of the first pressing member by patient both sides
The wall of the chest retracts, to obtain small notch internal mammary artery.And first mounting rod and the second mounting rod linked together by rack-plate, tooth
Batten can around the first mounting rod center axis thereof and be fixed on the first mounting rod, to make rack-plate and the other side
The angle formed between plane where the wall of the chest can be adjusted according to actual needs.To ensure to trigger chest of the part by the other side
The angle that wall triggers is sufficiently large, ensures that distraction angle is sufficiently large, surgical field of view is made fully to expose.Appear clear in breast and operation is empty
Between sufficiently large, the final convenience and certainty for ensureing surgical procedure.
Meanwhile one of trigger both part and the second pressing member and be selectively mounted to the second mounting rod, with installation
The first pressing member cooperation on to the first mounting rod, the wall of the chest of patient both sides is retracted or struts the breastbone of patient both sides.From
And make the retractor of the utility model that can either retract the wall of the chest when obtaining internal mammary artery, and appear surgical field of view, it also can be in bridge-
Target vessel retracts breastbone when coincideing, and appears anastomotic position.
It is last it is to be noted that：Above example is only to illustrate the technical solution of the utility model, rather than limits it
System.It will be understood by those of ordinary skill in the art that：Can with technical scheme described in the above embodiments is modified, or
