Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Please refer to fig. 1;

the bone grafting rod with the adjustable lower contact area has the similar or same use mode as the bone grafting rod in the prior art, and the difference is that the bottom area of the part of the bone grafting rod in contact with the human body is adjustable so as to meet the requirement in the operation;

in the prior art, the size of the bone grafting rod specification is divided into a size, for convenience of explanation, a smaller specification is called as a size, a larger specification is called as a size B, the smaller specification is selected as a reference, in the embodiment, the bottom area of the second pressing head 4 is smaller than or equal to that of the A, the bottom area of the second pressing head 4 penetrating through the conduction rod 2 is slightly larger than that of the first pressing head 3 but still smaller than that of the larger specification B, when the second pressing head 4 needs to be used, the second pressing head 4 slides down to the end part of the conduction rod 2, the first pressing head 3 is positioned in the first accommodating cavity 31, then the first pressing head 4 and the second pressing head are fixed, at the moment, the second pressing head 4 is positioned between the specifications A and the B, the third pressing head 6 can also penetrate through the conduction rod 2, the second accommodating cavity 61 is arranged in the third pressing head 6, when the third pressing head 6 needs to be used, the third pressing head 6 also slides down to the end part of the conduction rod 2, the second pressing head 4 is positioned in the second accommodating cavity 61, then the second pressing head is fixed, at the size, the size of the third pressing head 6 is still positioned between the specification A and the size, so that the size of the bone grafting rod can meet the size of the bone grafting rod specification, and the requirements of the bone grafting rod specification, and the bone grafting rod can meet the requirements of other specifications, and the bone grafting requirements of the bone grafting rod specification, and the bone grafting process, and the bone grafting rod.

When the first pressure head 3 and the third pressure head 6 are not needed, the first pressure head 3 and the third pressure head 6 can be fixed on the conducting rod through the fixing structure, the influence on the use is avoided, more specifically, the fixing structure comprises a magnet 51 arranged at the end part of the handle 1 and a thread 52 arranged at the position, close to the magnet 51, of the conducting rod 2, when the fixing is needed, the first pressure head 3 and the third pressure head 6 are fixed through the teeth of the thread 52 and move towards the handle 1, the first pressure head 3 and the third pressure head 6 are made to be adsorbed to the magnet 51, and the firmness is further improved.

It should be noted that, the conduction pole 2 in the utility model is made of non-magnetic material, for example plastics or non-magnetic metal etc. and pressure head 3 and pressure head three 6 are made of magnetic material, for example stainless steel, and when pressure head 3 cover was established on pressure head two 4, the two bottom surfaces flushed, when pressure head three 6 cover was established on pressure head 3, the three bottom surface flushed.

In this embodiment, one side that pressure head two 4 is close to pressure head one 3 is equipped with screw 52 hole, is equipped with on the pressure head one 3 and runs through the bolt that holds chamber one 31, bolt and screw 52 jogged joint, pressure head three 6 and pressure head two 4 fixed with the same reason.

In this embodiment, pressure head 3, pressure head two 4 and pressure head three 6 are the cylinder, and one side that handle 1 was kept away from to the three all is equipped with anti-skidding line.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
