[0028]如图1所示,本实施例中,该微创取骨装置包括:导向件100,导向件100的一端设有导入部110;空心环钻200,空心环钻200设有与导向件100导向配合的导向通道210,且空心环钻200的一端部设有贯通导向通道210的导入口212及设置于导入口212外边缘的切割部220;导套组件300,导套组件300包括导套本体310及设置于导套本体310的外侧壁的手持体320,导套本体310设有与导向件100导向配合的通孔312;及挖勺件400,挖勺件400的一端设有挖骨部、且挖骨部能够插入通孔312内。 [0028] 1, in the present embodiment, the Minimal Invasive apparatus comprising: a guide member 100, one end 100 of guide member 110 provided with an introduction portion; hollow 200 of the trephine, a hollow ring 200 is provided with a drill guide the guide member 100 with the guide channel 210, and an end portion of the hollow trephine 200 is provided through the guide passage 212 and the introduction port 210 is provided on an outer edge of the inlet port 212 cutting portion 220; guide sleeve assembly 300, 300 includes a guide sleeve assembly body 310 and the guide sleeve is provided in the outer wall of the guide sleeve 310 of the handset body 320, the guide sleeve body 310 and a through hole 100 of the guide 312 with the guide member; and digging spoon member 400, one end of the spoon member 400 is provided with a digging bone digging unit, and digging the bone portion can be inserted into the through hole 312.

[0029]上述微创取骨装置使用时,在取骨手术之前,先将取骨位置的外围组织切开,然后通过导入部110引导导向件100插入组织内,并对取骨位置进行定位。 When [0029] The device uses a minimally invasive bone graft, bone graft prior to surgery, bone graft first cutting position the surrounding tissue, and then by introducing the guide portion 110 guide member 100 is inserted into tissue, and the bone graft positioning position. 此时空心环钻200通过其导向通道210与导向件100的导向配合作用下,插入到取骨位置上,然后旋转空心环钻200,利用切割部220对取骨位置的骨膜、骨韧带等骨骼外围组织进行切割。 At this time, by fitting a hollow ring 200 which guide the drill guide channel 210 and guide member 100 under the effect of bone graft is inserted into position, and then rotating hollow trephine 200, cutting unit 220 by using the position taken periosteal bone, ligament and other bones peripheral tissue to be cut. 切割完成后,拔出空心环钻200,继续利用导向件100对取骨位置进行定位,进一步地手持手持体320插入导套本体310,利用其通孔312与导向件100的导向配合作用将导套本体310插入取骨位置中, 此时可拔出导向件100。 After cutting, pull hollow trephine 200, continue to use the position of the bone graft 100 pairs of positioning the guide member, holding the handset 320 is further inserted into the guide sleeve body 310 with which the through guide hole 312 and the guide member 100 cooperates with the guide bone graft sheath body 310 is inserted in position, the guide member 100 at this time can be removed. 最后利用挖勺件400,将挖骨部插入导套本体310的通孔312内,取出骨膜、骨韧带等组织,然后利用挖骨部对骨骼进行挖取,以获得自植骨体。 Finally digging spoon member 400, the digging portion inserted into the bone guide sleeve through hole 312 of the body 310, remove the periosteum, bone, ligaments and other tissues, and bone by using excavation scooping portions of bones to bone graft obtained from the body. 利用该微创取骨装置,利用导向件1〇〇的作用,可以重复准确地定位取骨位置,并利用空心环钻200对骨骼外围组织进行切割处理,再利用导套组件300及挖勺件400的配合实现骨骼的挖取,此过程中, 能够减小对骨组织的损伤,降低手术创伤,进而能够降低并发症的发生。 The bone graft using minimally invasive means, by the action of the guide member 1〇〇 can be repeated to accurately locate the position of bone graft, and trephine 200 pairs using hollow bone surrounding tissue cutting treatment, reuse assembly 300 and the guide sleeve member spoon digging 400 implemented with bone pick, this process can reduce damage to the bone tissue, reduced surgical trauma, complications can be reduced further.

[0030] 进一步地,在一实施例中,该挖骨件设有与超声手术设备相连接的连接部,进而构成超声勺刀,可进行刨骨、刮骨及挖骨等操作。 [0030] Further, in one embodiment, the bone digging member is provided with a connector portion connected to the ultrasonic surgical apparatus, and thus constitutes the ultrasonic spoon blade may be made of bone planing, scraping the bone and bone digging operations. 当然了,在其他实施例中,该挖骨件可直接人工操作进行取骨。 Of course, in other embodiments, the bone digging member may be directly manually operated bone graft.

[0031] 如图2所示,在本具体实施例中,该切割部220设有环状设置的锯齿体,以便于快速割断骨軔带、骨膜的骨骼外围组织。 [0031] As shown in FIG. 2, in the present embodiment, the cutting portion 220 is provided with an annular member disposed zigzag so as to quickly cut off the bone with bremsstrahlung, periosteal bone surrounding tissue.

[0032]当然了,在其他实施例中,该切割部220设有环状设置的切割刃,进而可以利用切割刃对骨韧带、骨膜的骨骼外围组织进行切割。 [0032] Of course, in other embodiments, the cutting portion 220 is provided with an annular cutting edge, and thus can be used for the cutting edge ligament, periosteum of bone surrounding tissue is cut.

[0033] 如图1及图2所示,在上述任一实施例的基础上,空心环钻200的另一端设有手柄结构230。 [0033] As shown in FIG. 1 and FIG. 2, on the basis of any preceding embodiment, the other end of the hollow 200 of the trephine is provided with a handle structure 230. 进而便于操作者施力旋转空心环钻200进行切割。 Further for the operator to force the rotation of the hollow 200 of the trephine cutting. 具体地,该手柄结构230与空心环钻200本体呈“T”字型,且手柄结构230设有夹握部232,以更加方便操作者握持该手柄结构230。 In particular, the grip structure 230 and the hollow 200 of the trephine generally "T" shaped, and the handle structure 230 has a gripping portion 232 for gripping by a more convenient operation of the handle structure 230.

[0034] 在上述任一实施例的基础上,导向件100呈中空筒状。 [0034] In any of the above on the basis of the embodiment, the guide member 100 has a hollow cylindrical shape. 该导向件100呈中空筒状,便于导向件1〇〇插入时,组织液及血液从中空处流出;同时该空心环钻2〇〇或导套本体310插入时,对人体组织的挤压所产生的组织液及血液也可从中空处流出,减少组织之间的液体挤压引起的损伤,避免出现血肿、腹胀等并发症。 The guide member 100 has a hollow cylindrical shape, when the guide member to facilitate insertion 1〇〇, blood and tissue fluid flows from the air; At the same time the hollow trephine 2〇〇 insertion guide sleeve 310 or body, resulting extruded human tissue blood and tissue fluid can flow out from the air, reduce the damage caused by squeezing the liquid between the tissue, to avoid hematoma, complications of abdominal distension. 具体地,该导向件1〇〇的导入部11〇呈锥角结构,便于平滑过渡。 In particular, the introduction guide member has a tapered portion 11〇 1〇〇 of the corner structure, to facilitate a smooth transition.

[0035] 进一步地,该导向件100的最大直径小于导向通道210的最小直径,进而便于该空心环钻200套设于导向件100的外壁,而与导向件1〇〇导向配合。 [0035] Further, the maximum diameter of the guide member 100 is smaller than the smallest diameter of the guide passage 210, thereby facilitating the hollow outer wall 100 of trephine 200 sleeved on the guide member, the guide members cooperate with the guide 1〇〇.
