It is fixedly connected with two centrum screws in hypocentrum screw hole with downside cone, is locked centrum screw using lock sheet.
Since above-mentioned cone screw is mostly walked on anterior cervical vertebrae, screw has strict demand into nail direction and angle,
Inaccuracy into nail direction may cause expendable wound to patient, therefore for the palm into nail direction and depth of screw
It is very crucial for holding, also very high to the technical requirements of doctor.
Utility model content
In consideration of it, the utility model provides a kind of brill guider of integrated angle adjustable, to assist doctor to carry out screw
Into nail, to reduce operation risk.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the brill guider of integrated angle adjustable,
It includes straight-bar and handle, and the straight-bar is fixedly arranged at the front end with a pivoted housing, rotatable guiding parts is provided on pivoted housing, described
Guiding parts has the first connecting portion that is connected with pivoted housing, the guide part with first connecting portion sequence, and setting the
Second connecting portion between one interconnecting piece and guide part, the guide part is in the closing in shape that front end is small, rear end is big comprising two
Symmetrically and the connecting plate of two C-shaped pipes of the C-shaped pipes of irrelevancy row and connection, have in the C-shaped pipes and to be passed through for drill point
Cavity.Preferably, positioning column is additionally provided in the front end of connecting plate.
Further, the front end of the C-shaped pipes is also provided with one group of stress slot.
Further, the side of the C-shaped pipes is additionally provided with reinforcement block, which protrudes the front end of guide part and be arranged.
Further, the pivoted housing have with straight-bar mutually fixed first piece of interconnecting piece and be connected with guiding parts the
Two pieces of interconnecting pieces.
Further, the inner cavity of second piece of interconnecting piece is provided with the stepped groove matched with first connecting portion,
The rear end of two pieces of interconnecting pieces is additionally provided with the end plug being connected with first connecting portion.
Further, second piece of interconnecting piece and straight-bar are in tilted layout, and inclination angle is 10-15 °.
The utility model has the beneficial effects that the utility model provides a kind of integrated drilling director of adjustable angle,
By two being arranged on guiding parts symmetrically and the C-shaped pipes of irrelevancy row, the angle of guiding parts is adjusted when work, directly
Positioning column on to guiding parts enters in the mounting hole on steel plate after positioning, then drill point is arranged to the cavity of corresponding C-shaped pipes
In.The utility model has the advantages that easy to use, accurate positioning, solve different patients because pedicle of vertebral arch angle difference cause into
The problems such as nail is not accurate, easily causes operative failure, damaged arteries, is worthy to be popularized and applies.
Below with reference to drawings and examples, the utility model is described in detail.
