Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The bone traction protection device of the present embodiment is generally used on the limbs needing bone traction, such as olecranon, lower radioulnar border, distal phalanx, femoral condyle, tibial tubercle, lower tibial end or calcaneus. The limbs are thin compared with the trunk, and the protective cover 2 can be well covered on the dragged part and provides effective protection.

Fig. 1 to 10 are schematic structural views of the bone distraction protection apparatus of the embodiment, and the cylinders in fig. 1 to 3 represent four limbs of a patient requiring bone distraction. Bone traction protection device establishes the safety cover 2 in patient's bone traction department both sides including being used for two covers respectively, and safety cover 2 is the hemisphere casing, and the edge of safety cover 2 is equipped with the recess 22 that two symmetries set up, recess 22 and the gentle transition in safety cover 2 edge. As shown in fig. 1 and 2, when two protection covers 2 are fixed at the bone traction position of a patient, the grooves 22 on different protection covers 2 are arranged oppositely, which more conforms to the radian of four limbs of the traction position of the patient, and ensures the fixing effect of the protection covers 2.

As shown in fig. 2, which is a schematic structural view of the protective covers 2 being pulled apart from each other, four fixing straps 3 are respectively arranged on one protective device, and the fixing straps 3 are distributed on two sides of the pulled portion in pairs, so as to stably fix the protective covers 2. Because the different drawn positions of different patients have different shapes and sizes, the fixed distance between the two protective covers 2 can be adjusted, and the fixing belt 3 can adopt a binding type or a drawing type to be suitable for different conditions. In this embodiment, the fixing band 3 is made of elastic material, so that the fixing is more convenient.

The both ends of fixed band 3 are fixed respectively on two safety cover 2 of difference, and patient's bone traction department is located the centre of two safety cover 2, and the relative bone traction department in bottom surface of two hemisphere safety cover 2 sets up. As shown in fig. 4, in order to facilitate fixing and replacing the fixing strap 3, a plurality of symmetrically disposed fixing holes 23 are formed at the edge of the protection cover 2, and the fixing strap 3 passes through the fixing holes 23 to fix the two protection covers 2 to each other.

Referring to fig. 5 and 6, which are schematic views of the internal structure of a single protection cover 2, the protection cover 2 is provided at the inner side thereof with a catching groove 21 for fixing the end of the bone traction pin 10, and the catching groove 21 is provided at the middle of the top of the protection cover 2. In clinic, after the bone traction needle 10 passes through a part needing traction, the two ends of the bone traction needle 10 are respectively clamped into the clamping grooves 21 in the two protective covers 2 by medical staff, and the clamping grooves 21 can further fix the bone traction needle 10, so that positive and stable bone traction is ensured.

As shown in fig. 7 and 8, the edge of the protective cover 2 is provided with a protective layer 4, the protective layer 4 is positioned between the edge of the protective cover 2 and the bone traction of the patient, and the protective layer 4 has elasticity. The protective layer 4 can increase the contact area of the edge of the protective cover 2 and the skin of a patient, and reduce the pressure injury to the skin caused by the edge of the protective cover 2 in the use process of the protective device.

In this embodiment, in order to ensure that the protection cover 2 can be suitable for different sizes of the pulled part, the notch of the groove 22 is provided with an extending portion 25 extending outwards, the edge of the extending portion 25 is in smooth transition with the edge of the protection cover 2, the protection layer 4 is arranged on the complete edge formed by the extending portion 25 and the protection cover 2, the extending portion 25 has elasticity, as shown in fig. 9 and 10, the arrangement of the extending portion 25 ensures that the protection cover 2 can be more attached to the pulled part of the patient, and the protection device can be stably fixed.

In addition, the safety cover 2 of this embodiment adopts transparent material, makes things convenient for medical personnel to observe the condition of being pull the department, and is equipped with a plurality of through-holes 24 on the safety cover 2, and through-hole 24 is convenient for outside being ventilative by the department of pulling, can also be used for the clearance by the department of pulling, makes things convenient for the treatment after the bone traction.

The above is the preferred embodiment of the present invention, and a person skilled in the art can make several modifications and improvements without departing from the principle of the present invention, and these should also be regarded as the protection scope of the present invention.
