Description

Technical Field

[0001] The utility model belongs to the technical field of medical supplies, and in particular relates to a bone traction fixation device. Background Art

[0002] Bone traction refers to the direct traction of bones through round pins, which can effectively reposition and fix the bones of patients with fractures and dislocations. It is often used for patients with skin injuries, severe swelling, wound infection or severe bone comminution who are not suitable for internal fixation.

[0003] After using a bone traction needle to traction the fractured tibia, the two sharp ends of the bone traction needle are exposed on the outside of the patient's leg, which is very dangerous. Generally, an empty ampoule is used to cover both ends of the bone traction needle. However, when this method is used clinically for bone traction, the connection between the bone traction needle and the empty ampoule is not stable enough, and the empty ampoule is easy to fall off from both ends of the bone traction needle.

[0004] The use of empty ampoule bottles set at both ends of the bone needle cannot fix the patient's limbs, which is not conducive to the patient's recovery. The bone traction needle is the bone needle. In summary, the bone traction surgery in the prior art has the problem of being unable to fix the patient's limbs. Utility Model Content

[0047] The jacks 11 are evenly distributed on the positioner.

[0048] The holes 11 can be arranged in a row on the positioner. When the holes 11 are evenly distributed on the positioner in the vertical direction, the bone needle 26 can only be adjusted in the height direction relative to the positioner.

[0049] When the insertion holes 11 are evenly distributed on the locator, the position of the bone pins 26 can be adjusted in the vertical direction and the horizontal direction relative to the locator, so that the locator has a wider application range.

[0050] Wherein: the cross-sectional shape of the positioner is a regular polygon; or the cross-sectional shape of the positioner is a regular triangle.

[0051] The cross-sectional shape of the positioner is preferably an equilateral triangle so that the positioner can be easily stored.

[0052] Specifically: the bone traction fixation device further comprises a base 2, the two positioners are both plugged into the base 2, and the base 2 is provided with an adjustment mechanism for adjusting the distance between the two positioners.

[0053] The base 2 includes a left base body 21 and a right base body 22 slidably connected to the left base body 21, one of the positioners is plugged into the left base body 21, and the other positioner is plugged into the right base body 22, and the adjustment mechanism includes a locking slider 23 for locking the position of the left base body 21 relative to the right base body 22.

[0054] In which: the locking slider 23 is slidably connected to the right seat body 22 along the width direction of the right seat body 22, the left seat body 21 is provided with a slide groove 211 that cooperates with the locking slider 23, and the left seat body 21 is also provided with a locking groove 212 that cooperates with the locking slider 23, the locking groove 212 is communicated with the slide groove 211, the slide groove 211 is arranged along the length direction of the right seat body 22, there are multiple locking grooves 212, and the locking grooves 212 are evenly distributed on the left seat body 21 along the length direction of the slide groove 211.

[0055] The upper end of the locking slider 23 protrudes out of the right base body 22 and extends into the slide groove 211 or the slot.

[0056] The right seat body 22 is provided with a sliding groove matched with the locking slider 23, and the locking slider 23 slides along the sliding groove.

[0057] A groove body for accommodating the right base body 22 may be provided on the left base body 21 to improve the position accuracy of the left base body 21 and the right base body 22 .

[0058] Specifically, both the left seat body 21 and the right seat body 22 are provided with a plug-in hole 24 , and the positioner is provided with a plug-in column 25 matched with the plug-in hole 24 .

[0059] The plug-in column 25 can be an integrated structure with the positioner.

[0060] The working principle of this embodiment:

[0061] First, the locking slider 23 is installed in the sliding groove of the right seat body 22 , so that the locking slider 23 slides along the sliding groove, and the sliding groove is arranged along the width direction of the right seat body 22 .

[0062] Then, the left base body 21 and the right base body 22 are assembled, and one end of the slide groove 211 on the left base body 21 can pass through the end surface of the left base body 21, or the right base body 22 and the left base body 21 can also be assembled through the elastic deformation of the left base body 21 to prevent the locking slider 23 from interfering with the left base body 21, so that the left base body 21 and the right base body 22 cannot be assembled correctly.

[0063] After the left base body 21 and the right base body 22 are assembled, the position of the locking slider 23 is adjusted so that the locking slider 23 is located in the slide groove 211. At this time, the position of the left base body 21 relative to the right base body 22 can be adjusted. After the positions of the left base body 21 and the right base body 22 are adjusted to the right position, the locking slider 23 is slid along the width direction of the right base body 22 so that the locking slider 23 enters the locking groove 212. At this time, the positions of the left base body 21 and the right base body 22 are locked.

[0064] Finally, the positioner is plugged into the left seat body 21 and the right seat body 22, and the patient's limb is placed in the positioning cavity 12 formed between the two positioners. The positioner and the base 2 cooperate to effectively position the patient's limb.

[0065] The insertion holes 24 on the left base body 21 and the right base body 22 can be evenly arranged along the length direction so that the position of the positioner on the left base body 21 and the right base body 22 can be adjusted, thereby making the distance between the two positioners have higher adjustment accuracy.

[0066] For example, after the positions of the left base body 21 and the right base body 22 are fixed, if the distance between the two positioners still does not meet the requirements, the positioners can be plugged into different plug holes 24 to accurately adjust the distance between the two positioners.

[0067] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model. However, no matter what changes are made in their shapes or structures, all technical schemes that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
