Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is further described。Wherein, being merely cited for property of accompanying drawing illustrates, expression is only schematic diagram, but not pictorial diagram, it is impossible to it is interpreted as the restriction to this patent；In order to of the present utility model embodiment is better described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product；It will be understood by those skilled in the art that some known features and explanation thereof are likely to omission and will be understood by accompanying drawing。
The corresponding same or analogous parts of same or analogous label in the accompanying drawing of this utility model embodiment；In description of the present utility model, it will be appreciated that, if have term " on ", D score, " left side ", orientation or the position relationship of the instruction such as " right side " are based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore term the being merely cited for property explanation of position relationship described in accompanying drawing, it is not intended that the restriction to this patent, for the ordinary skill in the art, the concrete meaning of above-mentioned term can be understood as the case may be。
Embodiment
The present embodiment one bone surgery grinding cutter structure as shown in Figures 1 to 4, including bistrique 1, outer tube 3, interior pipe 2 and bistrique cervical region 11, interior pipe 2 can around own axis and in be placed in outer tube 3；The two ends of bistrique cervical region 11 are fixing with bistrique 1 and interior pipe 2 front end respectively to be connected, and the intensity of bistrique cervical region 11 is more than the intensity of interior pipe 2, and bistrique cervical region 11 can adopt the steel matter of high intensity to make, when cutting osseous tissue, it is possible to prevent bistrique cervical region 11 from deforming；Outer tube 3 front end offers breach 21, and the two side of breach 21 is slope shape；Bistrique 1 is arranged in the position of outer tube 3 breach 21 so that on bistrique 1, partial denudation is in the front end of outer tube 3, so that bistrique 1 can be reached rotate shear action, the cutting edge on bistrique 1 is cross arrangement。
When carrying out bone surgery, when downright bad osseous tissue is distributed in 1 liang of side position of bistrique, interior pipe 2 is rotated clockwise relative to outer tube 3, namely the osseous tissue that machinable is downright bad clockwise, interior pipe 2 is rotated counterclockwise relative to outer tube 3, namely the osseous tissue that machinable is counterclockwise downright bad, reaches a wound and enters crossing and can cut the osseous tissue that both sides are downright bad, it is to avoid set up multiple wound mouth。This utility model can realize Double-directional rotary cutting, and this, while improving procedure efficiency, also mitigates the misery of patient。
Wherein, bistrique cervical region 11 offers suction socket 12, and suction socket 12 connects with interior pipe 2。Suction socket 12 and interior pipe 2 are collectively forming suction channel, when carrying out bone surgery, are connected with aspirator by interior pipe 2, can be pumped out by the necrotic bone tissue cut, and are beneficial to the carrying out of the clear of surgical field of view and operation technique。
It addition, be located proximate to one end that bistrique cervical region 11 is connected with bistrique 1 set by suction socket 12。So arrange and be more conducive to pump out the necrotic bone tissue cut in time, it is prevented that the osseous tissue machined away affects the visual field of doctor, and then affects being smoothed out of operation。
Wherein, the position of the maximum gauge of bistrique cervical region 11 coordinates with the inwall of outer tube 3。In rotating during pipe 2, the rotation that can make interior pipe 2 and bistrique cervical region 11 is so set being radially subject to rational constraint, makes interior pipe 2 and bistrique cervical region 11 that the vibration of clamping stagnation or bigger will not occur, it is to avoid to strengthen traumatic wounds, thus alleviating the misery of patient, improve surgical quality。
It addition, the position of the maximum gauge of bistrique cervical region 11 scribbles wear-resistant coating。When the osseous tissue that cutting is downright bad, interior pipe 2 band rotary bistrique cervical region 11 rotates relative to outer tube 3, now, bistrique cervical region 11 and outer tube 3 phase mutual friction, this is easily caused bistrique cervical region 11 and weares and teares, and the setting of wear-resistant coating adds the wearability of bistrique cervical region 11, is favorably improved the service life of bistrique cervical region 11。
Wherein, outer tube 3 is arranged with bistrique identification ring 4 away from one end of position set by bistrique 1, facilitates doctor and nurse to distinguish different classes of grinding cutter。
Obviously, above-described embodiment of the present utility model is only for clearly demonstrating this utility model example, and is not the restriction to embodiment of the present utility model。For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description。Here without also cannot all of embodiment be given exhaustive。All any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within this utility model scope of the claims。
