Description

一种可调节长度的骨科手术钻套 An adjustable orthopedic surgical drill sleeve length

技术领域 FIELD

[0001] 本实用新型涉及ー种医疗使用的器具,特别涉及一种可调节长度的骨科手术钻套的设计和制作。 [0001] The present invention relates to a medical appliance ー species used, in particular, relates to an adjustable length orthopedic drill sleeve design and production.

背景技术 Background technique

[0002] 钻套在骨组织钻孔中,具有定位和保护周围软组织的功能。 [0002] The drill bushing bore in bone tissue, the surrounding soft tissue protection and having a positioning function. 传统的骨科手术钻套其长度是固定的,不能通过调节钻套的长度,而获得控制钻头进入人体组织的深度,通常它是通过调节钻头上的限位器达到控制钻孔深度或凭经验完成。 Traditional orthopedic surgical drill sleeve whose length is fixed and can not be set by adjusting the length of the drill, the drill bit depth control is obtained into the body tissue, which is usually controlled by adjusting the drilling depth of the drill bit on the stopper or empirically complete . 由于调节钻头上的限位器时,需要助手使用专门匹配的扳手协助完成,整个过程繁琐,实用性较差。 Due to the adjustable stop on a drill bit, the need to use special assistant assist matching wrench, the whole process complicated, poor practicality. 因此,不少的临床医生凭钻头穿越骨组织后,钻压改变的手感来控制钻头深度,这样对病人的安全没有保障。 Therefore, many clinicians drill through the bone with the drill press to change the drill bit to control the depth of feeling, so there is no guarantee of patient safety. 为了解决骨科手术钻孔深度定位困难的问题,本实用新型研制一种可调节长度的骨科手术钻套,可根据手术的需要实时调节钻套的长度,达到控制钻孔的深度为目的,从而提高了骨科手术钻孔的安全性。 In order to solve the difficulties of drilling depth positioning of orthopedic surgery, the present invention is to develop a length adjustable orthopedic drill sleeve, drill sleeve may be adjusted in real time according to the length of the need for surgery, to control the depth of drilling for the purpose to improve the the safety of orthopedic surgery borehole.

实用新型内容 SUMMARY

[0003] 本实用新型的目的是提供一种可调节长度的骨科手术钻套,以克服目前骨科手术钻孔控制深度困难的缺点。 [0003] The object of the present invention is to provide an adjustable length orthopedic drill sleeve, orthopedic surgery to overcome the shortcomings currently difficult to control the depth of drilling.

[0004] 为了实现上述的目的,本实用新型提供的一种可调节长度的骨科手术钻套,包括外套筒I、与外套筒I相连接的手柄2,具体技术方案:在外套筒I上方,设置有带手轮4的可调节钻孔深度的套筒内芯3,所述的套筒内芯3下端设有外螺纹6与外套筒I的内螺纹相配合;该套筒内芯3上标记有钻套长度的刻度5 ;该外套筒I的底端还设置有锯齿状的突起7。 [0004] To achieve the foregoing object, a the present invention is capable of adjusting the length of the drill sleeve orthopedic surgery, comprising an outer sleeve I, the handle and the outer sleeve 2 is connected to I, the specific technical scheme: I outer sleeve above, is provided with a hand wheel with adjustable core drilling depth of the inner sleeve 3, 4, the lower end of the inner sleeve of the core 3 cooperates with an internal thread the external thread of the outer sleeve 6 I; the inner sleeve 5 is marked with a scale length of the core drill bushing 3; I is the bottom end of the outer sleeve is also provided with a serrated protrusion 7.

[0005] 采用上述措施的本实用新型具有结构简单、容易制造、成本低廉、使用方便快捷,使骨科手术钻孔更安全、更可靠的优点。 The present invention is simple in structure, easy to manufacture, inexpensive, convenient to use, so that drilling orthopedic surgery safer and more reliable the advantage of [0005] having the above measures.

[0006] 下面结合附图对本实用新型再进ー步详细的说明。 [0006] The present invention further ー then into the detailed description below in conjunction with the accompanying drawings.

附图说明 BRIEF DESCRIPTION

[0007] 图I是本实用新型的立体示意图。 [0007] Figure I is a perspective view of the present invention.

具体实施方式 detailed description

[0008] 參考图1,图I是本实用新型的立体示意图,从图中可看出本实用新型具体结构,包括外套筒I、与外套筒I相连接的手柄2,具体实施方式:在外套筒I上方,设置有带手轮4的可调节钻孔深度的套筒内芯3,该套筒内芯3下端设有外螺纹6与外套筒I的内螺纹相配合;该套筒内芯3上标记有钻套长度的刻度5,目的是旋转套筒内芯3上的手轮4吋,从刻度5可清楚看出所控制钻孔的深度。 [0008] Referring to FIG 1, FIG. I is a schematic perspective view of the novel present invention, the present invention can be seen from the drawing a specific configuration, including I outer sleeve, the outer sleeve 2 is connected to the handle I, particular embodiments: I over the outer sleeve, provided with a hand wheel with adjustable core drilling depth of the inner sleeve 34, the lower end of the inner sleeve of the core 3 cooperates with an internal thread the external thread of the outer sleeve 6 I; the set of 3 labeled with the cylinder core drill scale length of the sleeve 5, the purpose of the handwheel 4 is 3-inch rotary sleeve on the core, the scale 5 is clear from the drilling depth is controlled. 该外套筒I的底端还设置有锯齿状的突起7,目的是在钻孔时,使外套筒I不容易产生移动,固定得更加牢固。 I bottom end of the outer sleeve is also provided with serrated projections 7, when the object is drilled, the outer sleeve I is not prone to move, more solid fixation. [0009] 本实用新型通过调节套筒内芯3上的手轮4,就可以实现所需要控制钻孔的深度,使用非常方便。 [0009] the present invention by adjusting the hand wheel 4 within a sleeve on the core 3, the control can achieve a desired drilling depth, very convenient to use.
