技术领域 FIELD

[0001] 本实用新型涉及医疗器械技术领域,尤其是涉及一种用于对钻头起到定位、导向作用的滑动定位导向装置。 [0001] The present invention relates to a technical field of medical devices, particularly to a drill bit for positioning play, the sliding action of the guide means positioning guide.

背景技术 Background technique

[0002] 随着社会发展及社会老龄化,老年人骨折在骨科中所占比例越来越大,对于老年骨折病人,骨科医生在治疗时一般希望采用微创手术方法来减小手术对病人二次打击,对于老年病人的恢复尤为重要,但在微创手术治疗中,由于切口较小,术野暴露不充分,钻头/克氏针定位不准确,从而延长手术时间、增加手术中风险。 [0002] With the social development and the aging society, the elderly fractures in orthopedics growing proportion, in elderly patients with fractures, orthopedic surgeons in the treatment is generally desirable to reduce the use of minimally invasive surgical procedure on the patient two times hit, is particularly important for elderly patients to recover, but in minimally invasive surgery, because of the smaller incision, the surgical field exposure is not sufficient, drill / Kirschner positioning is not accurate, thus extending the operative time, increased surgical risk. 骨科医生在进行骨折手术治疗时,通过牵引、翘拨等手术方法,将骨折断端复位后,用持骨钳或克氏针将骨折断端临时固定,然后再用钢板固定骨折断端;有时用克氏针固定骨折断端后,可以将克氏针用做导针、用空心钻钻孔,然后拧入空心螺钉来固定骨折断端;再有对于撕脱性骨折、断端粉碎、或开放性骨折等情况,直接用克氏针固定骨折断端,对于这些情况均需要克氏针能够准确的从预先设计好的进针点进针,从理想的出针点出针。 Surgical orthopedic surgeon during surgical treatment of fractures, by pulling, etc. Alice aside, after resetting the fracture site, bone holding forceps or Kirschner wire with the fracture site is temporarily fixed, and then ends the fracture fixation plate; sometimes after fixation with Kirschner wire fracture site, Kirschner wire may be used as the guide pin, with a hollow drill the borehole, and a hollow screw screwed into the fracture site is fixed; Note that for avulsion fracture, comminuted ends, or like the case of open fractures, pinning the fracture site directly, for these cases are needed to accurately Kirschner from pre-designed needle point into the needle, preferably the needle from the needle point.

[0003] 但是在手术操作过程中,克氏针的穿入点、穿出点及打入方向全凭术者经验,克氏针的方向和位置不能精确控制,在使用时要做到每次准确穿入、穿出克氏针难度较大,因此对手术造成困难,由于穿入克氏针位置不理想,造成骨折块固定不牢固,往下操作时,会造成骨折断端再次错位,被迫反复穿针,造成软组织损伤,延长手术时间,增加感染的风险。 [0003] However, during a surgical operation, Kirschner penetration point and exit point in the driving direction depends on the surgeon's experience, Kirschner direction and position can not be precisely controlled, when used to do each time exact penetration, piercing Kirschner difficult, thus resulting in difficult operation, since the Kirschner wire penetration position is not ideal, resulting in fracture of the block is not firmly fixed, when down operation, again causes displacement of fracture fragments is forcing repeated needle, causing soft tissue injury, prolonged operative time, increase the risk of infection.

[0004] 公开号为CN102836002A的实用新型专利公开了一种克氏针导向装置(申请号CN201210332021.4),包括中空环状固定圈、至少两个对称地轴向贯穿固定圈内的压板,固定圈和压板之间有加压螺母连接,可以通过其调节固定圈和压板之间的距离,压板端设有固定器,固定器上设有与克氏针导向器螺纹向配套的螺孔,使用时将中空环状固定圈套入患肢中,通过压板将骨折断端复位、固定,通过定位器上的克氏针导向器打入克氏针,从而固定骨折断端。 [0004] Publication No. CN102836002A Utility Model Kirschner discloses a guide apparatus (Application No. CN201210332021.4), comprises a hollow annular fixing ring, at least two axially symmetrical circle through the fixed platen, the fixed between the platen and the pressing ring nut connection, the distance between the fixed ring and which can be adjusted by platen, the platen is provided with a fixed end, it is provided with threaded Kirschner guide supporting the screw, the holder using when the hollow ring-shaped fixing limb into the trap by the platen reset the fracture site, fixing, by Kirschner Kirschner wire into the guides on the retainer so as to fix the fracture site. 这种克氏针导向装置的克氏针导向器位置固定,确定好进针点时、出针点的位置也同时确定,临床使用中有时需要分别确定进针点和出针点,这种情况使定位装置在使用不够灵活;同时这种装置对于手足部肌肉组织少、骨体积小效果较好,对于其他肌肉丰富部位、骨体积较大的骨折在需要准确定位时不实用。 Kirschner Kirschner guide means which guide fixed location, determining when the needle point is good, the position of the needle point is also determined, clinical use is sometimes necessary to determine the needle point and the needle points, respectively, this positioning the device in use inflexible; while such devices for hand and foot musculature small, small bone volume better, other muscle-rich parts of the larger volume of bone fractures when required accurate positioning is not practical.
