It is as follows that this utility model solves the problems of the technologies described above the technical scheme that adopts:

A kind of skull tractor external member, include skull tractor, bone drill, counterweight bag and pull rope, wherein, skull tractor is the Ti alloy skull bone tractor, skull tractor includes two traction bows that cooperatively interact and connect and can spacing by jointed shaft, the bone drill periphery is nested with stopper, and the axial lateral surface of this bone drill is shaped with the scale label groove.

For optimizing technique scheme, the concrete measure of taking also comprises:

Each above-mentioned traction bow includes traction bow, traction bow body and the traction bow tail of the structure that is connected,

Above-mentioned traction bow is equipped with hook-shaped screw, is equipped with adjusting nut on the hook-shaped screw.

An above-mentioned traction bow end pin is connected to adjusting bolt, and another traction bow urogenesis has bolt indentation, is equipped with each hold-down nut that is positioned at bolt indentation (13) both sides on the adjusting bolt.

Above-mentioned jointed shaft is set with the traction button.

Above-mentioned stopper and bone drill are for being threaded.

Above-mentioned counterweight bag is canvas counterweight bag, and in this counterweight bag counterweight is housed.

The information labels card is posted in above-mentioned counterweight bag outside.

Above-mentioned counterweight bag is provided with the messenger mouth.

Compared with prior art, a kind of skull tractor external member of the present utility model, include skull tractor, bone drill, counterweight bag and pull rope, wherein, skull tractor is the Ti alloy skull bone tractor, skull tractor includes two traction bows that cooperatively interact and connect and can spacing by jointed shaft, and the bone drill periphery is nested with stopper, and the axial lateral surface of this bone drill is shaped with the scale label groove.

Main part of the present utility model is that the whole parts of skull tractor are the titanium alloy material making, when doing nuclear magnetic resonance, NMR (MRI) inspection, need not like this repeated disassembled and assembled skull tractor, so not only alleviate patient's misery, also simplified a lot of operation sequences for medical personnel.Simultaneously, the drill bit in the external member has the insurance retention device, pierces the cranium cerebral tissue in the dark damage skull in the time of can avoiding like this when bit bore causing bit bore because of the degree of depth that is not easy to control drill bit, causes catastrophic effect; And having scale can understand the degree of depth of inserting needle on the drill bit, stopper and drill bit can be adjusted the degree of depth that pierces of drill bit so easily for being threaded.In addition, adopted bag-shaped counterweight in the external member, made by canvas, counterweight places the counterweight bag, and is convenient attractive in appearance, can also avoid tradition to make the drawback of traction of sliding weight of steelyard or iron block simultaneously, as when moving sick bed, sliding weight of steelyard or iron block come off easily and cause the foot that injures medical personnel by a crashing object; The counterweight bag is designed with the information labels card outward, the personal information of record patient, and the situations such as the beginning and ending time of traction and trailing weight, the change of illness state after being convenient in time understand conditions of patients and draw.

This utility model energy compatible nuclear magnetic resonance, NMR (MRI) alleviates the patient suffering, simplifies the medical care program, and the penetration depth of drill bit can carry out regulation and control easily simultaneously, has increased the safety of skull traction.This utility model also has operation principle and simple in structure, and is simple to operate clear, the advantage that is conducive to apply.
