Abstract

This utility model discloses a flower-type anchoring nail, one hollow tube, both ends have the open type lids, the front end of anchoring nail has the side lug, the tube wall has the longitudinal diamond grooves to form the deformation bridge among them, the outer wall at both ends of hollow tube has the concave hollow recess, the inner wall of tube at the most narrow deformation bridge has the outward opened recess. This flower-type anchoring nail may deform under the squeezing of special equipment, let the deformation bridge extrude outward and fold to form the anchoring hook, transversely squeeze and fix the muscle tendon; the side lug may hook the muscle tendon to longitudinally pull and fix the muscle tendon; thus, this utility model may have the double functions of longitudinal traction fixing and transverse squeeze fixing, and easy to operate.

Description

花形锚钉 Flower-shaped anchors

一、 技术领域 First, the technical field

本实用新型涉及一种医疗器械,更特别的是关于一种用于骨科手术中将肌腱、人工韧带等材料固定到骨内的花形锚钉。 The present invention relates to a medical device, and more particularly relates to a tendon in the orthopedic surgery, artificial ligaments and other materials for the flower-shaped anchor is fixed to the bone.

二、 背景技术 Second, the technical background

在很多骨科手术中需要肌腱移植并将肌腱固定到骨质内,比如膝关节交 In many orthopedic surgery need tendon graft fixed to the bone and tendon, such as the cross the knee joint

叉韧带重建手术。 Fork ligament reconstruction surgery. 固定肌腱的方法大致分为四类: The method of fixing the tendon roughly divided into four categories:

一类是骨表面固定,比如把肌腱缝合在骨表面上,或通过螺钉,门形钉等器材固定,此方法缺点是开放手术,运用范围有限; One is fixed bone surface, such as the tendons sutured on the bone surface, or fixed by screws, staples and other equipment doors, open surgery is disadvantage of this method, using a limited range;

二类是骨桥固定,也就是将肌腱穿入骨孔后再从另一个骨孔穿出后形成 Type II osteopontin is fixed, i.e. through the bone hole after the tendon is formed from the pierced hole after another bone

环形袢将肌腱固定,此方法缺点是操作困难,需要切开手术等; Fixing the annular tendon loop, a disadvantage of this method is difficult to handle, require incision and the like;

三类是纵向固定,将肌腱穿过骨髓道后末端夯柱固定,比如Endo-button, 此方法缺点是肌腱与骨的愈合不牢固; Three are longitudinally fixed, the end of the tendon through the ram channel pillar fixing bone marrow, such as Endo-button, the disadvantages of this method is not healing tendon to bone securely;

四类是横向固定,将肌腱挤压在骨髓道的壁上,比如界面钉,此方法缺点是纵向固定不牢。 Four transverse fixation, tendon marrow pressed against the wall of the channel, such as nail interface, this method is not strong disadvantage is longitudinally fixed.

三、 实用新型内容 III. SUMMARY

本实用新型的目的是提供一种即具备纵向牵拉固定又具备横向挤压固定双重优点,特别适合于非开放的关节镜手术的花形锚钉。 The object of the present invention is to provide a fixing that is provided with longitudinal drawing and includes a fixed transverse extrusion double advantage, especially for the non-anchor flower open arthroscopic surgery.

本实用新型的这些及其他目的将通过下列详细说明和描述来进一步展现。 The present invention These and other objects will be further demonstrated and described by the following detailed description.

本实用新型的花形锚钉,为一空心管,两端为开口式盒盖,在锚钉前端具有侧耳,管壁上开有纵向菱形变形槽,槽与槽之间形成变形桥,在在空心管两端外壁上开有内陷浅凹沟,在变形桥最窄处的管道内壁上开有向外的凹 The present invention flower-shaped anchor, as a hollow tube, open at both ends of formula lid, having ears in the front end of the anchor, the wall opening is formed with a deformable bridge between the longitudinal grooves rhomboidity groove and the groove in the hollow an outer wall of the tube ends sunk shallow grooves opened, outwardly open recess in a pipe wall deformation at the narrowest bridge

沟。 ditch.

进一步的,上述变形槽数量为6~8个,变形桥数量为6〜8个,侧耳数量为2~4个。 Further, the number of the grooves are deformed 6 to 8, the number of deformed bridge 6 ~ 8, the number of ear 2 to 4.

本实用新型的花形锚钉在使用特定器械挤压下可以发生形变,使变形桥向外突出折叠,形成锚钩,对肌腱横向挤压固定;而侧耳则可钩桂肌腱,对肌腱纵向牵拉固定;这样,本实用新型就即具备纵向牵拉固定又具备横向挤压固定双重作用,而且操作简单。 The present invention flower-shaped anchor be deformed under the pressed using a specific instrument, the deformed bridge projecting outwardly folded to form anchor, tendon fixed lateral extrusion; the ear hook can Gui tendons, tendon longitudinal drawing fixed; Thus, the present invention includes a longitudinal drawing i.e. it is fixed and includes a fixed transverse extrusion dual role, and simple operation.

图中,符号l代表开口式盒盖,符号2代表变形槽,符号3代表变形桥, 符号4代表凹沟,符号5代表侧耳。 FIG, symbol representative of open type lid l, the symbol represents deformable tank, 3 represents a modification bridge symbol, symbol 4 denotes grooves, reference numeral 5 denotes ear. 具体实施方式 detailed description

以下结合附图说明本实用新型的结构。 BRIEF DESCRIPTION The following structures of the present invention.

本实用新型的花形锚钉,为一空心管,两端为开口式盒盖,在锚钉前端具有侧耳,管壁上开有纵向菱形变形槽,槽与槽之间形成变形桥,在在空心管两端外壁上开有内陷浅凹沟,在变形桥最窄处的管道内壁上开有向外的凹沟。 The present invention flower-shaped anchor, as a hollow tube, open at both ends of formula lid, having ears in the front end of the anchor, the wall opening is formed with a deformable bridge between the longitudinal grooves rhomboidity groove and the groove in the hollow an outer wall of the tube ends opened retraction shallow grooves, the grooves opening outwardly in the pipe wall deformation at the narrowest bridge.

本实用新型为"受压变形"结构,当本锚钉受到纵向压力后,膨胀变形, 使变形桥沿预先开好的凹沟向外突起后折叠形成锚钩,插入骨质之内,起到横向固定锚钉自身和固定肌腱的作用。 The present invention is a "compressive deformation" structure, when subjected to longitudinal stress present anchor, expansion and deformation, the deformed bridge along the good pre-opened grooves formed projecting outwardly folded fluke, is inserted into the bone, the functions transverse fixation anchor fixing effect of its own and tendon. 而锚钉的侧耳结构,则可牵拉肌腱, 并防止其滑脱,保证纵向固定,锚钉前端开口式盒盖,用于配合挤压器械的使用,后端的盒盖则用于取出本锚钉。 The ear structure of the anchor can be pulled tendons, and to prevent it from slipping, to ensure longitudinal fixing anchor lid front opening type, used in the extrusion devices for engaging the rear end of the cover for extracting the anchor of the present .
