Description

Fixed frame and reset system

Technical field

The present invention relates to the field of medical equipment, specifically, to a fixation frame and a reset system.

Background technique

At present, clinical fracture reduction mainly uses reduction clamps or combined external fixators.

Reduction with forceps is mainly done through the doctor's technique and experience and requires the assistance of multiple people to complete the reduction. The combined external fixator mainly achieves the reduction and positioning of the fracture site through a combination of multiple product accessories.

During the research, it was found that the existing combined external fixator has at least the following shortcomings when used:

The existing combined external fixator is inconvenient to adjust when reducing the fracture site. The combined external fixator has many product parts and multiple combination methods, which are complicated to operate. It is difficult to apply it flexibly without professional and long-term training. Especially for complex cases, if the assembly method is wrong, it will cause many serious adverse reactions. In addition, for lower limb surgery patients, the combined external fixator is bulky, which is not conducive to the patient's normal daily activities, causing the patient to stay in bed for a long time and causing other complications.

Please refer to Figure 4. This embodiment provides a reset system 01, including a fixing nail 002 and the fixing frame 001 provided in the above-mentioned Embodiment 1. The fixing nail 002 is fixed on the body 101 of the first connecting member 100 or/and the second On the connector 180.

A specific application of this embodiment is as follows:

Please refer to Figure 4. The reset system 01 includes a fixation frame 001 and four fixation nails 002. Two fixing nails 002 form one group, and four fixing nails 002 are divided into two groups. Two fixation nails 002 of the same group are implanted in one bone segment, and two sets of fixation nails 002 are respectively implanted in two bone segments. Then, two sets of fixing nails 002 correspond to the two first connectors 100 one by one. The two fixing nails 002 of the same group are installed on one first connector 100 respectively. The two fixing nails 002 of the same group are installed along the first connecting member 100 . The body 101 of the connector 100 has intervals in the length direction. Then, adjust the fixation frame 001 according to the patient's normal bone position and length, for example, adjust the angle of the first connecting member 100 and the second connecting member 180 so that the two bone segments are approximately parallel, and then rotate the adjusting ring 140 so that The two bone segments are approximately at the same height, and then the adjusting sleeve 123 is rotated to make the two bone segments relatively close to each other for docking or relatively far apart for separation, so that the two bone segments after adjustment have the same position and length as the normal bone. The adjusting ring 140 and the adjusting sleeve 123 are locked to complete the adjustment and positioning of the fracture position.

Please refer to FIG. 5 . In other embodiments, the second supporting member 170 can be installed on the first connecting member 100 , and then the fixing nails 002 can be installed on both the first connecting member 100 and the second connecting member 180 . Select as needed. Yes, no specific enumeration will be given here.

It should be noted that the fixing nail 002 provided in this embodiment is directly fixed on the first connecting member 100 or the second connecting member 180, and its height does not need to be adjusted. The length of the fixing nail 002 is fixed and is not implanted in the human body. The length is short and does not require cutting or sawing, making it easy and safe to use.

Please refer to Figures 6-7. Optionally, the fixing nail 002 includes a nail sleeve 200, a nail rod 210, a pressing block 220, a clamping block 230 and a nut 240 with an internal hexagon. The nut 240, the clamping block 220 and the clamping block 230 are connected to the nail sleeve 200 and are arranged at intervals along the axial direction of the nail sleeve 200. One end of the nail rod 210 is in the shape of a ball head, and the ball head end of the nail rod 210 is clamped between the pressure block 220 and the clamping block 230. , the first connector 100 is inserted between the nut 240 and the pressure block 220. Tightening the nut 240 can cause the first connector 100 to be clamped between the nut 240 and the pressure block 220, and the nail rod 210 to be clamped on the pressure block. between block 220 and clamping block 230. The nail rod 210 has a ball head end, and the angle of the nail rod 210 relative to the nail sleeve 200 can be adjusted within a certain range, and has a wide range of use.

Obviously, in other embodiments, the fixing nail 002 can also have other structures.

The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
