Description
Technical field
This utility model belongs to the medical apparatus and instruments technical field, relates to the cancellous bone screw of using in a kind of bone surgery.
Background technology
In the fracture fixation operation, need to use cancellous bone screw, and cancellous bone screw needs and pad is used.But find when taking out cancellous bone screw and pad that after cancellous bone screw takes out, and at this moment pad has been given birth to adhesion with the set of bones hair-weaving in the later stage, pad can not taken out of with the taking-up of screw, need open big otch, increase damage and painful, bring many inconvenience to the doctor to patient.
The utility model content
Technical problem to be solved in the utility model provides a kind of cancellous bone screw, and this cancellous bone screw can be communicated with pad and take out together when taking out, thereby overcomes the problem that the pad that exists in the prior art takes out inconvenience.
In order to solve the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of cancellous bone screw, comprise shank of screw, be positioned at the shank of screw tail end screw cap, it is characterized in that: described screw cap below has the pad with the screw cap one.
Adopt technique scheme, by pad and screw cap are made of one structure, when getting screw, pad together must be taken out like this, therefore, cancellous bone screw of the present utility model has the pad of taking-up and is easy to advantage and then helps reducing patient's misery.
Description of drawings
Be elaborated below in conjunction with the drawings and specific embodiments this utility model:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 100-shank of screw, 101-tapered thread, 200-screw cap, 300-pad.
?
The specific embodiment
As shown in Figure 1, cancellous bone screw of the present utility model, comprise shank of screw 100, be positioned at the screw cap 200 of shank of screw 100 tail ends, wherein the Lower Half of shank of screw 100 has tapered thread 101, in addition, have pad 300 below screw cap 200, this pad 300 is structure as a whole with screw cap 200.
In this utility model,, when getting screw, pad 300 together must be taken out like this by pad 300 and screw cap 200 are made of one structure.Because pad 300 can conveniently take out, and therefore, helps reducing patient and passes through.
