Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of skull fracture fixation, and particularly relates to a skull fracture block fixing plate. BACKGROUND
[0002] Skull fracture is usually caused by violent impact on the skull, often damages one or more skull bones, and leads to partial or complete fracture of the skull. Skull fracture is not easy to be found, and symptoms include swelling and tenderness around the injured area, facial abrasions, bleeding from the nostrils or ears, etc. Most mild skull fractures will heal on their own. Severe skull fractures accompanied by severe intracranial injury need surgical treatment, and the prognosis is generally good after timely treatment.
[0003] Skull fractures can be classified according to the fracture pattern as linear fracture, depressed fracture, comminuted fracture, hole-shaped fracture, and penetrating fracture. Most skull fractures are caused by impact or heavy blows to the head. The skull has a certain degree of elasticity. When the external force acting on the head is large, the deformation of the skull exceeds its elastic limit, resulting in skull fracture. If the impact is strong and the area is small, the skull will mainly deform locally, often causing a depressed fracture, and the accompanying brain injury is also relatively limited. If the force is large in area and small in intensity, it is easy to cause overall deformation of the skull, resulting in multiple linear fractures or comminuted fractures. How to repair the skull after fracture is a difficult problem that needs to be solved in the field. SUMMARY

[0022] In order to make the person in the art better understand the utility model scheme, the utility model will be further described in detail below in combination with the drawings and specific embodiments.
[0023] In this article, the terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the drawings, and according to the different drawings, the corresponding positional relationship may also change accordingly, therefore, it cannot be understood as an absolute limitation on the scope of protection; moreover, the relationship terms such as "first" and "second" are only used to distinguish one from another with the same name of the parts, and do not necessarily require or imply any such actual relationship or order between the parts.
[0024] Embodiment
[0025] As Figures 1-4 shown, the embodiment discloses a skull fracture block fixing plate, comprising: a first connecting part 2, a first connecting hole is arranged on the first connecting part 2, the first connecting hole is provided with a first connecting piece 5, the first connecting part 2 is connected to the first bone 1 through the first connecting piece 5; a second connecting part 4, the second connecting part 4 is connected to the first connecting part 2, the second connecting part 4 is provided with a second connecting hole 6, the second connecting hole 6 is provided with a first connecting piece 5, and the second connecting part 4 is connected to the second bone 9 through the first connecting piece 5.
[0026] Specifically, in the process of repairing skull fracture, the first connecting part 2 of the skull fracture block fixing plate is connected to the first bone 1 through the first connecting piece 5 and the first connecting hole, the first bone 1 is a healthy bone, the second connecting part 4 of the skull fracture block fixing plate is connected to the second bone 9 through the first connecting piece 5 and the second connecting hole 6, the second bone 9 is a concave fracture caused by skull fracture, and the concave fracture caused by skull fracture is well fixed through the first connecting part 2 and the second connecting part 4, which is beneficial to the postoperative repair of skull fracture.
[0027] Preferably, the first connecting part 2 and the second connecting part 4 are integrally formed.
[0028] Further, the first connecting part 2 comprises: at least two first connecting holes, the at least two first connecting holes are arranged in a transverse direction on the first connecting part 2. The transverse direction is the width direction of the first connecting part 2, by arranging two first connecting holes arranged in a transverse direction, the volume of the first connecting part 2 can be reduced while enhancing the connecting force between the first connecting part 2 and the first bone 1, and the flexibility of the skull fracture block fixing plate is improved on the basis of ensuring the connecting strength.
[0029] Further, the second connecting part 4 comprises: a plurality of second connecting holes 6, the plurality of second connecting holes 6 are arranged in a longitudinal direction on the second connecting part 4. The longitudinal direction is the length direction of the second connecting part 4, by arranging a plurality of second connecting holes 6 arranged in a longitudinal direction, the connecting strength between the second connecting part 4 and the second bone 9 can be effectively enhanced.
[0030] Further, the vertical extension 7 is arranged on the second connecting part 4, and the supporting part 8 is connected to the vertical extension 7. Since the second bone 9 is not necessarily a whole bone, when a comminuted fracture or other fracture with bone fragments 3 is encountered, the second bone 9 includes a whole bone and a plurality of bone fragments 3, and the plurality of bone fragments 3 is difficult to be connected by the first connecting part 5. At this time, the supporting part 8 supports the bone fragments 3, effectively fixing the bone fragments 3. The plurality of second connecting holes 6 arranged on the second connecting part 4 in the longitudinal direction is also conducive to the second connecting part 4 to pass through the bone fragments 3 area, and form a connection with the second bone 9 in the whole bone area. The vertical extension 7 is preferably integrally formed with the second connecting part 4, and the vertical extension 7 is preferably integrally formed with the supporting part 8.
[0031] As shown in Figure 5 Further, the cross section of the supporting part 8 is any one of a rectangle, an arc, or a trapezoid. The cross section of the supporting part 8 is determined according to the shape of the bone fragments 3, and the cross-sectional area is not limited herein.
[0032] Further, an arc-shaped transition part is arranged at the connection between the vertical extension 7 and the supporting part 8. The arc-shaped transition part can effectively reduce stress concentration and improve the service life of the vertical extension 7 and the supporting part 8.
[0033] The above technical features can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
