3、 发明内容 3. SUMMARY OF THE INVENTION

本实用新型的H的是克服现有技术中存在的不足,提供一种方便调节,使用方便的安全颅骨手术钻。 H of the present invention is to overcome the deficiencies present in the prior art, to provide a convenient adjustment, easy to secure the skull surgical drill.

本实用新型的技术方案是按以下方式实现的,其结构由固定圆盘、圆环、螺纹连杆、旋转手柄、伸縮杆、钻头和定位环构成,定位环通过圆心对称的两侧固定有两根伸縮杆,伸縮杆的上端固定在固定圆盘上,固定圆盘的中部固定有圆环, 圆环内部通过螺纹连接有螺纹连杆,螺纹连杆的上、下端分别固定有旋转手柄和钻头。 Aspect of the present invention is accomplished in the following manner, by a structure fixed disc, annular, threaded rod, rotation of the handle, telescopic rod, and the drill bit retaining ring configuration, through the center of symmetry of the retaining ring is fixed to two sides telescopic poles, the upper end of the telescopic rod is fixed to the fixed disc, fixed disc fixed to the central ring, the inner ring is connected to the threaded rod, the threaded rod by the threaded lower end of the handle are fixed and rotary drill bit .

上述的伸縮杆上设置有紧固旋钮,下部设置有刻度值。 The above-described telescopic rod is provided with a tightening knob, the lower portion is provided with a scale value. 上述的圆环内部设置有内螺纹,内螺纹与螺纹连杆上的螺纹相吻合。 Inside of the ring with an internal thread is provided above the threads on the threaded rod with the internal threads coincide. 使用时,首先调节紧固旋钮使伸缩杆伸长到适合的长度,然后将钻头的下端对准相应的位置,再将定位环放到颅骨上即可,最后通过转动旋转手柄带动钻头旋转,转动的过程可以及时发现钻头与设定的位置是否出现偏差,当钻头钻透颅骨后旋转手柄随即无法进行转动。 In use, the adjusting knob to the fastening of extension to a suitable length, and then the lower end of the drill bit with the corresponding position, and then placed on the positioning ring to the skull, and finally driven drill bit is rotated by rotating the handle, the rotation the process may detect whether the position of the drill bit and a set deviation, the drill bit to drill through the skull when the rotation of the handle can not then be rotated. 本实用新型的优点是: (1)、本手术钻下端的定位环可以有效地卡在颅骨上,起到防止钻头位置或方向出现偏差而影响手术操作的目的。 The advantages of the present invention is: (1), the lower end of the present surgical drill can be effectively positioning ring card in the skull, location or orientation of the drill bit serves to prevent the deviation and Objective surgical procedure.

(2) 、可以通过调节伸縮杆的长度而提前设定好钻头进入颅骨的深度,有效避免钻头损伤脑组织的情况出现。 (2), the drill bit may be set up in advance by adjusting the penetration depth of the skull of the telescopic rod length, the bit effectively avoid brain damage.

(3) 、本装置具有结构简单,使用方便,体积小等优点。 (3), the present apparatus has a simple structure, easy to use, small volume.
