Description

一种对胫骨平台塌陷骨折块准确打入导针的导向装置 One kind of collapse of the fracture fragments of tibial plateau accurately guide the needle into the guide means

技术领域 FIELD

[0001]本发明涉及一种对胫骨平台塌陷骨折块打入导针的精准导向装置,属于骨科医疗器械技术领域。 [0001] The present invention relates to an apparatus for accurately guiding the collapse of the fracture fragments of tibial plateau into the guide pin, the technical field belonging to the orthopedic medical device.

背景技术 Background technique

[0002]胫骨平台骨折是常见的关节内骨折,多合并关节面塌陷,根据受伤时膝关节所处状态、外力大小及方向的不同,塌陷骨折块形态存在较大差异。 [0002] tibial plateau fractures are common intra-articular fracture, collapse and more with the articular surface, according to the state in which injured knee joint, the magnitude and direction of external forces of different collapse are quite different form the fracture fragments. 随着CT技术、三维模拟技术的普及和微创手术的发展,关节囊外顶压复位塌陷骨折块成为治疗首选。 With the popularization and development of minimally invasive surgical techniques CT, 3D simulation technology, the reset pressed against the joint capsule fracture block become the primary collapse. 但是由于这种复位过程不破坏关节囊,无法在直视下定位塌陷骨折块,因此如何在闭合状态下定位塌陷骨折块成为微创治疗胫骨平台骨折手术的关键。 However, since such a reset process does not destroy the joint capsule, unable to locate a block of collapse fracture under direct vision, so how is positioned in the closed state of collapse fracture of a key block of tibial plateau fractures minimally invasive surgery. 传统方法需在手术过程中借助C型臂X线透视机进行,医生凭经验在正、侧位透视下将导针置于塌陷骨折块下方完成定位。 Required by the conventional method in the procedure C arm type X-ray machine for the doctor empirically positive, lateral perspective view of the guide pin block placed under the complete collapse of the fracture orientation. 传统方法存在以下缺点: The conventional method has the following disadvantages:

[0003] 1.对手术操作人员的空间定位能力要求较高,只有微创手术经验丰富的医师能够完成该操作,需要较长时间的学习和操作实践; [0003] 1. spatial orientation of the surgical operators demanding, and only minimally invasive surgery experienced physician to complete the operation, it takes a long time to learn and operating practices;

[0004] 2.很难将导针一次性置于塌陷骨折块下方,即手术中需多次改变导针方向后才可确定最终进针角度,破坏骨质较多且延长手术时间; [0004] 2. difficult disposable needle guide disposed below the collapse of the fracture fragments, i.e. before surgery to determine the final angle of the needle, with bone destruction and extend the operation time to be repeated after changing the direction of the guide pin;

[0005] 3.手术过程中需要多次进行透视,过多的放射线暴露对医患双方的健康不利,尤其是医生需要经常进行手术操作,严重影响了健康,因此制约了手术的进行; [0005] 3. The surgical procedure involves frequently perspective, excessive radiation exposure to both doctors and patients on the adverse health, especially doctors require frequent surgical procedure, a serious impact on health, and therefore restricted the surgery;

[0006] 4.手术操作人员在尝试定位塌陷骨折块时,导针置入角度过大有可能误伤胭窝处神经血管,对患者造成严重伤害。 [0006] 4. The operator personnel when attempting to locate fractures collapse block, the guide pin placement angle is too great popliteal fossa may injure nerves and blood vessels, causing serious injury to the patient.

[0007] 目前,随着微创手术的大量开展,在闭合状态下打入导针的情况越来越普遍,如何能在各种手术中准确定位导针打入的方向和角度,同时避免长时间的X线照射的问题一直没有得到有效地解决,成为制约骨科微创手术高质量实施的因素之一,因此十分有必要研制出一种能够在闭合状态下准确打入导针的导向装置,以满足骨科微创手术快速发展的需要。 [0007] Currently, as a large number of minimally invasive surgery, where a guide pin into the closed state in the more common, how accurate positioning and angular orientation of the guide pin into the various procedures while avoiding long X-ray irradiation time problem has not been effectively solved, one of the factors restricting embodiment of the orthopedic quality of minimally invasive surgery, it is therefore imperative to develop a closed state capable of accurately guiding the needle into the guide means, to meet the needs of rapid development of minimally invasive orthopedic surgery.
