Description
Technical field
This utility model relates to technical field of medical instrument, specifically a kind of orthopedic drill.
Background technology
Existing orthopedic drill adopts motor to drive borer, needs manually to hold perpendicularity, and easily rock when holing during boring, causes the precision of boring low, and waste of manpower, and the time of at substantial is in boring.In addition, existing, borer without insurance depth stop device, in use procedure, cannot ensure drilling depth, experienced medical personnel can the even keyhole degree of depth well, but, for abecedarian or the personnel that lack experience, in use there will be the problem that boring is excessively dark, thus be damaged to tissue, abnormally dangerous.
Utility model content
The purpose of this utility model is to provide one precisely to hold drilling depth, the orthopedic drill that precision is high, safe and reliable, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of orthopedic drill, comprise drive motors, drill bit, slide bar, rotating shaft and flat board, described slide bar upper end sidewall is provided with graduation mark, slide bar lower end is installed and is provided with rotating shaft, rotating shaft lower end is connected with feet, described dull and stereotyped lower end middle position is provided with drive motors, drive motors is connected with drill bit by installing connecting rods, dull and stereotyped two ends are respectively arranged with sliding sleeve, sliding sleeve is set on slide bar and is connected with sliding bar, slide bar below sliding sleeve is arranged with slide cartridge, slide cartridge sidewall is provided with set bolt, Compress Spring is connected with between slide cartridge upper end and sliding sleeve lower end, described slide cartridge sidewall is also provided with postive stop baffle, on installing connecting rods, corresponding postive stop baffle fixed cover is provided with limited block.
Further, described feet is the tapered sucker in cross section.
Further, described top end of sliding rod is provided with back-up ring plate.
Further, described dull and stereotyped upper end is provided with handle, and described handle, at its lower end is provided with anti-skidding finger groove.
The beneficial effects of the utility model are: by the cooperation of slide bar, rotating shaft and feet, ensure that in boring procedure, drill bit is vertical with boring surface of bone, alleviates the operation easier in narrow lacuna internal drilling; Coordinated by the postive stop baffle on the limited block on installing connecting rods and slide cartridge sidewall, effectively can limit drilling depth, guarantee drilling safe; Slide cartridge and sliding sleeve are provided with Compress Spring, avoid the action of gravity slide downward sliding over self, thus avoid the process causing drill bit to fall under self to damage patient; Slide bar upper end sidewall is provided with graduation mark, the depth length of drill bit can be observed in real time, facilitate the medical worker of abecedarian and lack of experience to operate, save the plenty of time.To sum up, this utility model structure is simple, time saving and energy saving, facilitates the medical worker of abecedarian and lack of experience to operate, safe and reliable.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of orthopedic drill.
In figure: 1-handle, the anti-skidding finger groove of 2-, 3-is dull and stereotyped, 4-back-up ring plate, 5-sliding sleeve, 6-Compress Spring, 7-slide cartridge, 8-slide bar, 9-rotating shaft, 10-feet, 11-limited block, 12-installing connecting rods, 13-drill bit, 14-postive stop baffle, 15-drive motors, 16-set bolt, 17-graduation mark.
Detailed description of the invention
