具体实施方式 Detailed ways

[0014] 下面结合附图对本发明做详细说明,实施例的用途仅在于解释本发明而非限定技术方案。 [0014] DRAWINGS The present invention is made in detail, only in the use of the embodiment of the present invention is not construed to limit the technical solutions.

[0015] 实施例1.请参见图1,一种用于软组织隧道的拉钩,包括手柄I和工作端2,所述手柄I与工作端2成30— 60度夹角,优选45度夹角,工作端2呈半圆筒状,包括手柄连接端22、末端23和侧壁24,其侧壁24上设置若干小孔21。 [0015] Example 1. See Figures 1 A soft tissue retractors for tunnels, comprising a handle and a working end I 2, I working end of the handle 2 into the 30-60 degree angle, preferably a 45 degree angle , working end 2 a semi-cylindrical shape, comprising a handle connection end 22, end 23 and side walls 24, a plurality of apertures 21 disposed on the side wall 24.

[0016] 继续参见图1,工作端2呈半圆筒状,想成半个隧道空间。 [0016] With continued reference to FIG. 1, the working end 2 a semi-cylindrical shape, like a tunnel as a half space. 优选手柄连接端22的直径略大于末端23的直径。 Preferably handle connecting end 22 slightly larger than the diameter of the end 23. 侧壁24设置若干小孔,可以容纳穿颊器的放置,也能起到排水的作用。 Side wall 24 is provided a plurality of apertures, disposed to accommodate wear's cheek, also play a role drainage. 手柄连接端22的直径可以略大于末端23的直径,这样操作时容易插入软组织,比较方便拉钩作用;两端直径相等也不影响操作,只是拉钩插入时需要较大作用力;末端的直径也可以缩小为一个圆钝的点,这样插入时更容易,但如果缩小为一个圆钝的点,会减少侧壁上的小孔,也即减少穿颊器的操作空间。 Diameter end connected to the handle 22 may be slightly larger than the diameter of the tip 23 is easily inserted into the soft tissue during this operation, more convenient retractors effect; operation is not affected at both ends are equal in diameter, but requires a large force when the retractor is inserted; tip diameter may be reduced to a blunt point, when so inserted more easily, but if the reduction is a blunt point, will reduce the aperture on the side walls, i.e., to reduce the operating space cheek's wear.

[0017] 工作端2的长度可以调节。 Length [0017] 2 working end may be adjusted. 可以把工作端设计成套嵌的两段式,通过旋转螺母调节其长度,或者通过套嵌的卡槽固位,拉长或缩短其长度。 The working end may be embedded in two-stage design of the package, adjusting its length by rotation of the nut or by nested retention slot, lengthened or shortened its length.

[0018] 手柄I上设置手柄孔11,手术操作时手指可以钩在手柄孔处施加作用力。 Set [0018] I the handle grip aperture 11, the finger can be hooked when the operator applied force on the handle hole.

[0019] 请参见图2,作为另一个优选实施例,具有圆筒状工作端2',工作端操作时形成完整的隧道空间。 [0019] Referring to FIG. 2, as a further preferred embodiment, has a cylindrical working end 2 'to form a complete tunnel space working end operation.

[0020] 以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。 [0020] The above are only preferred embodiments of the present invention, it should be noted that for those of ordinary skill in the art, without departing from the principles of the present invention is provided, can make various improvements and modifications, improvements and modifications of these also it is considered the scope of the present invention.
