Characterized by: semi -circular left branch brace (1) and semicircle right branch brace (2) are formed by two interior concave corrosion resistant plate preparation respectively, the one end of semi -circular left branch brace (1) and semicircle right branch brace (2) is together articulated by connecting axle (3), the medial surface of connecting axle (3) is equipped with pretension spring (4), the lateral surface of the other end of semi -circular left branch brace (1) and semi -circular right branch brace (2) is equipped with solid pin nut (5), gu be equipped with solid round pin screw rod (6) on pin nut (5). The utility model discloses, simple structure, convenient to use when going the skull windowing for the patient, can fully expose the operation field of vision, and labour saving and time saving has reduced art person's working strength, has improved the success rate of skull windowing.
Description
Technical field: this utility model belongs to medical instruments field, particularly one is when for patient's row skull windowing, fully can expose surgical field of view, and structure is simple, and skull easy to use is windowed scalp dilator.
Background technology: in neurosurgery, skull windowing is a kind of conventional art formula, in this art formula, needs the scalp tissue around tractive operative incision, fully to expose surgical field of view.At present, be not specifically designed to the scalp dilator of skull windowing clinically, assistant can only be relied on the scalp tissue around otch to be pulled open to both sides with drag hook, assistant is when drawing drag hook, need the dynamics that long-time maintenance is identical, to ensure that the exposure size of surgical field of view is maintained, so waste time and energy very much, surgical field of view to appear degree also undesirable, operating time is usually caused to extend, add the misery of patient and the working strength of medical worker, serve unnecessary loss and misery to doctor and patient band.
Summary of the invention: the purpose of this utility model is to provide a kind of fully can expose surgical field of view when for patient's row skull windowing, structure simply, window scalp dilator by skull easy to use.
For achieving the above object, this utility model takes following technical scheme: this skull is windowed scalp dilator, by semi-circular left support arm, semicircle right support arm, connecting axle and preloading spring are formed, semi-circular left support arm and semicircle right support arm are made by the corrosion resistant plate of two panels concave shaped respectively, one end of semi-circular left support arm and semicircle right support arm is hinged by connecting axle, the medial surface of connecting axle is provided with preloading spring, the lateral surface of the other end of semi-circular left support arm and semicircle right support arm is provided with solid pin nut, Gu pin nut is provided with solid pin screw rod.
This utility model, structure is simple, easy to use, when for patient's row skull windowing, fully can expose surgical field of view, time saving and energy saving, reduces the working strength of patient, improves the success rate of skull windowing.
Accompanying drawing illustrates: below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
With reference to accompanying drawing 1,1, semi-circular left support arm, 2, semicircle right support arm, 3, connecting axle, 4, preloading spring, 5, solid pin nut, 6, admittedly sell screw rod.
Detailed description of the invention: this utility model, be made up of semi-circular left support arm 1, semicircle right support arm 2, connecting axle 3 and preloading spring 4, semi-circular left support arm 1 and semicircle right support arm 2 are made by the corrosion resistant plate of two panels concave shaped respectively, one end of semi-circular left support arm 1 and semicircle right support arm 2 is hinged by connecting axle 3, the medial surface of connecting axle 3 is provided with preloading spring 4, the lateral surface of the other end of semi-circular left support arm 1 and semicircle right support arm 2 is provided with solid pin nut 5, Gu pin nut 5 is provided with solid pin screw rod 6.
When using this utility model, the operation technique first pressing skull windowing is conventional, operative region is successively cut, is separated, until skull surface, then this utility model is put into the skull surface implementing windowing, semi-circular left support arm 1 and semicircle right support arm 2 are supportted large to suitable angle under the effect of preloading spring 4, with solid pin nut 5 and admittedly pin screw rod 6 fix.
