Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an anatomical titanium plate for the scapula. Background Technology

[0002] With the increasing number of patients suffering from high-energy injuries each year, the incidence of scapular fractures in clinical practice is also rising. Scapular fractures account for approximately 3% to 5% of shoulder fractures and 0.5% to 1% of all fractures, primarily affecting the body and glenoid neck, accounting for 62% to 98%. Previously, most scapular fractures were treated conservatively. However, for scapular fractures with severe displacement of the fracture ends and joint instability, surgical internal fixation is more conducive to the recovery of shoulder joint function after injury. After all, conservative treatment can lead to fracture complications such as chronic shoulder pain, limited range of motion, and joint stiffness.

[0003] Surgical treatment of scapular body fractures often involves internal fixation with a reconstructive titanium plate. This requires shaping the titanium plate intraoperatively and placing it at the fracture site. The adhesion of the internal fixation device needs to be repeatedly checked under direct vision and C-arm fluoroscopy to achieve strong fixation of the fracture site. However, repeated bending of the reconstructive titanium plate may cause a decrease in fixation strength, screw loosening or falling out, leading to a decline in shoulder joint function. Furthermore, the pre-bent titanium plate may cause screws to enter the joint cavity due to incorrect screw insertion direction. Utility Model Content

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0025] like Figure 1-3 As shown, this utility model provides an anatomical scapular titanium plate, including a first titanium plate 1, a second titanium plate 2, and at least two connecting rods 3; the at least two connecting rods 3 are arranged side by side between the first titanium plate 1 and the second titanium plate 2.

[0026] The first titanium plate 1 includes a medial scapular titanium plate 4 and a scapular spine titanium plate 5; the medial scapular titanium plate 4 and the scapular spine titanium plate 5 are fixedly connected; the medial scapular titanium plate 4 is uniformly provided with at least two first locking screw holes 6 along its length; the scapular spine titanium plate 5 is uniformly provided with at least two second locking screw holes 7 along its length; the second titanium plate 2 includes a lateral scapular titanium plate 8 and a glenoid titanium plate 9; the lateral scapular titanium plate 8 and the glenoid titanium plate 9 are fixedly connected; the lateral scapular titanium plate 8 is uniformly provided with at least two third locking screw holes 10 along its length; the glenoid titanium plate 9 is uniformly provided with at least two fourth locking screw holes 11 along its length.

[0027] One end of each of the above-mentioned connecting rods 3 is fixedly connected to the titanium plate 4 on the medial edge of the scapula; the other end of each of the above-mentioned connecting rods 3 is fixedly connected to the titanium plate 8 on the lateral edge of the scapula.

[0028] In some embodiments, an anatomical scapular titanium plate is developed through data measurement of the anatomical morphology of the scapula, printing and molding, designing the shape of the titanium plate, designing the screw angle, performing digital virtual inspection, and physical in-situ inspection. This anatomical scapular titanium plate includes a first titanium plate 1, a second titanium plate 2, and at least two connecting rods 3. For example, there can be three connecting rods 3 arranged side-by-side between the first titanium plate 1 and the second titanium plate 2, thus forming an integrated anatomical scapular titanium plate. In practical use, because the entire structure is a titanium plate, the pure titanium material is easy to bend and shape, thus allowing for customization according to different patient anatomy. The scapular titanium plate is specially shaped to resemble the anatomical form of the scapula, eliminating the need for pre-bending and conforming to human anatomical characteristics. This facilitates surgery for orthopedic surgeons, making the procedure quicker and easier, shortening surgical time. The one-piece structure also provides better fixation for comminuted fractures, reducing the likelihood of fracture fragment displacement. The first titanium plate 1 includes a medial scapular border titanium plate 4 and a scapular spine titanium plate 5, with the medial scapular border titanium plate 4 and the scapular spine titanium plate 5 fixedly connected, forming a single piece. The medial scapular border titanium plate 4 matches the shape of the medial border of the scapula, i.e., the vertebral border of the scapula. In actual use, the shoulder... The medial scapular titanium plate 4 fits against the medial border of the human scapula, and at least two first locking screw holes 6 are evenly distributed along its length to achieve fitting and fixation with the medial scapula. The scapular spine titanium plate 5 matches the shape of the human scapular spine. In actual use, the scapular spine titanium plate 5 fits against the human scapular spine, and at least two second locking screw holes 7 are evenly distributed along its length to achieve fitting and fixation with the scapular spine. The second titanium plate 2 includes a lateral scapular titanium plate 8 and a glenoid titanium plate 9, and the lateral scapular edge is fixedly connected to the glenoid titanium plate 9, i.e., the second titanium plate 2. The system is constructed as a single unit. The lateral scapular titanium plate 8 matches the shape of the lateral scapula (axillary border) of the human scapula. In actual use, the lateral scapular titanium plate 8 fits snugly against the lateral scapula of the human body, and at least two third locking screw holes 10 are evenly distributed along its length to achieve a snug fit and fixation with the lateral scapula. The glenoid titanium plate 9 matches the shape of the glenoid fossa of the human body. In actual use, the glenoid titanium plate 9 fits snugly against the glenoid fossa of the human body, and at least two fourth locking screw holes 11 are evenly distributed along its length to achieve a snug fit and fixation with the glenoid fossa. Specifically, for the connecting rod 3, one end of each connecting rod 3 is fixedly connected to the medial scapular titanium plate 4, and the other end is fixedly connected to the lateral scapular titanium plate 8.

[0029] In other embodiments, the number of links 3 can be set according to actual conditions.

[0030] In this invention, the anatomical scapular titanium plate further includes at least two first locking screws 12; the distance between each pair of adjacent first locking screw holes 6 is 12mm ± 1mm; the shape of the first locking screw hole 6 matches the shape of the first locking screw 12; the first locking screw 12 is detachably connected to the scapular medial edge titanium plate 4 through the first locking screw hole 6.

[0031] In some embodiments, such as Figure 1-3 As shown, the number of first locking screws 12 can be 6, the number of first locking screw holes 6 can be 6, and the distance between any two adjacent first locking screw holes 6 is 12mm ± 1mm, preferably 12mm; the distance between any two adjacent first locking screws 12 is 12mm ± 1mm, preferably 12mm; the shape of the first locking screw hole 6 matches the shape of the first locking screw 12, therefore, the first locking screw 12 is detachably connected to the titanium plate 4 of the medial edge of the scapula through the first locking screw hole 6; in actual use, since the titanium plate 4 of the medial edge of the scapula is in contact with the medial edge of the scapula, the titanium plate 4 of the medial edge of the scapula and the medial edge of the scapula can be fixed in contact through the first locking screw 12. Specifically, after the first locking screw 12 is screwed into the first locking screw hole 6 on the titanium plate 4 of the medial edge of the scapula, the rotation can be controlled to achieve reliable fixation between the titanium plate 4 of the medial edge of the scapula and the medial edge of the scapula. The rigid locking mechanism formed by the first locking screw and the first locking screw hole ensures a stable fit between the titanium plate on the medial border of the scapula and the medial border of the scapula, preventing the first locking screw from tilting or sliding within the bone. Furthermore, the design of multiple first locking screws and multiple first locking screw holes avoids local bone resorption due to stress loss.

[0032] In other embodiments, the number of first locking screws 12 and the number of first locking screw holes 6 can be set according to actual conditions.

[0033] In this invention, the anatomical scapular titanium plate further includes at least two second locking screws 13; the distance between each pair of adjacent second locking screw holes 7 is 12mm ± 1mm; the shape of the second locking screw hole 7 matches the shape of the second locking screw 13; the second locking screw 13 is detachably connected to the scapular titanium plate 5 through the second locking screw hole 7.

[0034] In some embodiments, such as Figure 1-3As shown, the number of second locking screws 13 can be 4, and the number of second locking screw holes 7 can be 4. The distance between any two adjacent second locking screw holes 7 is 12mm ± 1mm, preferably 12mm. The distance between any two adjacent second locking screws 13 is 12mm ± 1mm, preferably 12mm. The shape of the second locking screw hole 7 matches the shape of the second locking screw 13. Therefore, the second locking screw 13 is detachably connected to the scapular spine titanium plate 5 through the second locking screw hole 7. In actual use, since the scapular spine titanium plate 5 is in contact with the scapular spine, the scapular spine titanium plate 5 and the scapular spine can be fixed by the second locking screw 13. Specifically, after the second locking screw 13 is screwed into the second locking screw hole 7 on the scapular spine titanium plate 5, the rotation can be controlled to achieve reliable fixation between the scapular spine titanium plate 5 and the scapular spine. The rigid locking mechanism formed by the second locking screw and the second locking screw hole ensures a stable fit between the scapular spine titanium plate and the scapular spine, preventing the second locking screw from tilting or sliding within the bone. Furthermore, the design of multiple second locking screws and multiple second locking screw holes avoids local bone resorption due to stress loss.

[0035] In other embodiments, the number of second locking screws 13 and the number of second locking screw holes 7 can be set according to actual conditions.

[0036] In this invention, the anatomical scapular titanium plate further includes at least two third locking screws 14; the distance between each pair of adjacent third locking screw holes 10 is 12mm ± 1mm; the shape of the third locking screw hole 10 matches the shape of the third locking screw 14; the third locking screw 14 is detachably connected to the lateral edge titanium plate 8 of the scapula through the third locking screw hole 10.

[0037] In some embodiments, such as Figure 1-3As shown, the number of third locking screws 14 can be 6, and the number of third locking screw holes 10 can be 6. The distance between any two adjacent third locking screw holes 10 is 12mm ± 1mm, preferably 12mm. The distance between any two adjacent third locking screws 14 is 12mm ± 1mm, preferably 12mm. The shape of the third locking screw hole 10 matches the shape of the third locking screw 14. Therefore, the third locking screw 14 is detachably connected to the scapular spine titanium plate 5 through the third locking screw hole 10. In actual use, since the lateral edge titanium plate 8 of the scapula is in contact with the lateral edge of the scapula, the lateral edge titanium plate 8 of the scapula and the lateral edge of the scapula can be fixed by the third locking screw 14. Specifically, after the third locking screw 14 is screwed into the third locking screw hole 10 on the lateral edge titanium plate 8, the rotation can be controlled to achieve reliable fixation between the lateral edge titanium plate 8 of the scapula and the lateral edge of the scapula. The rigid locking mechanism formed by the third locking screw and the third locking screw hole ensures a stable fit between the titanium plate on the lateral edge of the scapula and the lateral edge of the scapula, preventing the third locking screw from tilting or sliding within the bone. Furthermore, the design of multiple third locking screws and multiple third locking screw holes avoids local bone resorption due to stress loss.

[0038] In other embodiments, the number of third locking screws 14 and the number of third locking screw holes 10 can be set according to actual conditions.

[0039] In this invention, the anatomical scapular titanium plate further includes at least two fourth locking screws 15; the distance between each pair of adjacent fourth locking screw holes 11 is 12mm ± 1mm; the shape of the fourth locking screw hole 11 matches the shape of the fourth locking screw 15; the fourth locking screw 15 is detachably connected to the glenoid titanium plate 9 through the fourth locking screw hole 11.

[0040] In some embodiments, such as Figure 1-3As shown, the number of fourth locking screws 15 can be 2, and the number of fourth locking screw holes 11 can be 2. The distance between any two adjacent fourth locking screw holes 11 is 12mm ± 1mm, preferably 12mm. The distance between any two adjacent fourth locking screws 15 is 12mm ± 1mm, preferably 12mm. The shape of the fourth locking screw hole 11 matches the shape of the fourth locking screw 15. Therefore, the fourth locking screw 15 is detachably connected to the glenoid plate 9 through the fourth locking screw hole 11. In actual use, since the glenoid plate 9 is in contact with the glenoid, the glenoid plate 9 and the glenoid can be fixed together by the fourth locking screw 15. Specifically, after the fourth locking screw 15 is screwed into the fourth locking screw hole 11 on the glenoid plate 9, the rotation can be controlled to achieve reliable fixation between the glenoid plate 9 and the glenoid. The fourth locking screw and the fourth locking screw hole form a rigid lock, which makes the glenoid plate and the glenoid stable and fixed, preventing the fourth locking screw from tilting or sliding in the bone; and the design of multiple fourth locking screws and multiple fourth locking screw holes avoids local bone absorption due to stress loss.

[0041] In other embodiments, the number of fourth locking screws 15 and the number of fourth locking screw holes 11 can be set according to actual conditions.

[0042] The first locking screw hole 6, the second locking screw hole 7, the third locking screw hole 10, and the fourth locking screw hole 11 form a set of locking screw holes; the diameter of each locking screw hole in the set is 2.7mm ± 0.5mm; the first locking screw 12, the second locking screw 13, the third locking screw 14, and the fourth locking screw 15 form a set of locking screws; the diameter of each locking screw in the set is 2.7mm ± 0.5mm.

[0043] In some embodiments, the first locking screw hole 6, the second locking screw hole 7, the third locking screw hole 10, and the fourth locking screw hole 11 form a set of locking screw holes in the anatomical scapular titanium plate, and the size of each locking screw hole in the set can be the same, that is, each locking screw hole can be 2.7mm±0.5mm, preferably 2.7mm; the first locking screw 12, the second locking screw 13, the third locking screw 14, and the fourth locking screw 15 form a set of locking screws in the anatomical scapular titanium plate, and the size of each locking screw in the set can be the same, that is, each locking screw can be 2.7mm±0.5mm, preferably 2.7mm. By setting locking screws and locking holes of the same size, the threads of the two can fit perfectly, forming a gapless mechanical connection and achieving absolute rigid fixation. There is no micro-movement between the locking screw and the titanium plate, which can resist the rotational and shear forces generated during scapular movement and prevent the displacement of fracture fragments. Moreover, the size matching maximizes the contact area between the locking screw and the locking hole, and the stress is distributed throughout the thread interface rather than concentrated at a local point, reducing the risk of locking screw breakage or titanium plate fatigue.

[0044] In this invention, the length between the connection point of the titanium plate 4 on the medial edge of the scapula and the titanium plate 5 on the scapula spine and the titanium plate 9 on the glenoid fossa is 70mm ± 5mm.

[0045] In some embodiments, such as Figure 3 As shown, Figure 3 Point A is the junction of the medial border titanium plate 4 and the scapular spine titanium plate 5. The vertical height between point A and the glenoid plate 9 is... Figure 3 The value of b is 70mm ± 5mm, preferably 70mm. By setting an appropriate spacing, the shape of the anatomical scapular titanium plate is made closer to the anatomical shape of the human scapula, which helps to better fit and fix the anatomical scapular titanium plate to various parts of the scapula, and improves the shaping effect.

[0046] In this invention, the length between the side of the glenoid plate 9 away from the lateral edge of the scapula titanium plate 8 and the side of the medial edge of the scapula titanium plate 4 away from the scapular spine titanium plate 5 is 115mm ± 5mm.

[0047] In some embodiments, such as Figure 3 As shown, Figure 3 Point B is the side of the glenoid plate 9 furthest from the lateral border of the scapula, which is the side of the titanium plate 8. Figure 3 Point C is the side of the scapular medial border titanium plate 4 away from the scapular spine titanium plate 5. The horizontal length value between B and C is... Figure 3The value of 'a' is 115mm ± 5mm, preferably 115mm. By setting an appropriate length value, the shape of the anatomical scapular titanium plate is made closer to the anatomical shape of the human scapula, making the structure more reasonable and helping to better fit and fix the anatomical scapular titanium plate to various parts of the scapula.

[0048] In this invention, the thickness of the first titanium plate 1 is 1.4mm-1.6mm; the thickness of the second titanium plate 2 is 1.4mm-1.6mm; and the thickness of each connecting rod 3 is 1.4mm-1.6mm.

[0049] In some embodiments, the thickness of the first titanium plate 1 is 1.4mm-1.6mm, preferably 1.5mm; the thickness of the second titanium plate 2 is 1.4mm-1.6mm, preferably 1.5mm; and the thickness of each link 3 is 1.4mm-1.6mm, preferably 1.5mm. By using a thin titanium bone plate, the anatomical scapular titanium plate is thin and elastic, with high strength, close to the elastic modulus of bone, easy to place during surgery, improving the fixation effect of the anatomical scapular titanium plate, and suitable for various complex types of scapular body fractures.

[0050] In this invention, both sidewalls of the first titanium plate 1 are wavy; both sidewalls of the lateral edge titanium plate 8 of the scapula are wavy.

[0051] In some embodiments, such as Figure 1-3 As shown, in the first titanium plate 1, both the medial border titanium plate 4 and the scapular spine titanium plate 5 have wavy sidewalls, as do both sidewalls of the lateral border titanium plate 8. By setting the titanium plates with wavy sidewalls, the titanium plates can precisely conform to irregular bone surfaces, reducing the gap between the titanium plates and the bones, and making the titanium plates more closely match the shape of the scapula.

[0052] The working principle of this anatomical scapular titanium plate is as follows:

[0053] When anatomical scapular titanium plates are required, the medial scapular titanium plate 4 is attached to the medial scapula of the human body, the scapular spine titanium plate 5 is attached to the scapular spine of the human body, the lateral scapular titanium plate 8 is attached to the lateral scapula of the human body, and the glenoid titanium plate 9 is attached to the glenoid of the human body. Then, the medial scapular titanium plate 4 is attached and fixed to the medial scapula of the human body using the first locking screw 12 and the first locking screw hole 6, the scapular spine titanium plate 5 is attached and fixed to the scapular spine of the human body using the second locking screw 13 and the second locking screw hole 7, the lateral scapular titanium plate 8 is attached and fixed to the lateral scapula of the human body using the third locking screw 14 and the third locking screw hole 10, and the glenoid titanium plate 9 is attached and fixed to the glenoid of the human body using the fourth locking screw 15 and the fourth locking screw hole 11.

[0054] The beneficial effects of this utility model are:

By connecting the first and second titanium plates with a connecting rod, the medial border titanium plate, the scapular spine titanium plate, the lateral border titanium plate, and the glenoid titanium plate of the scapula are integrated into one unit, forming an integrated anatomical scapular titanium plate. This improves the stability of the anatomical scapular titanium plate, and the design of the titanium plate facilitates bending and shaping during surgery, reducing the difficulty of intraoperative operation. It is suitable for various complex types of scapular body fractures. By setting locking screw holes and locking screws, the fixation strength of the anatomical scapular titanium plate is improved, achieving close fixation between the anatomical scapular titanium plate and the scapula, reducing the risk of postoperative loss of reduction.
