Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, it relates to a palmar locking plate fixation mechanism. Background Art

[0002] The radius is one of the two long bones in the human forearm, located on the outer side of the forearm (close to the palmar side), running parallel to the ulna and jointly constituting the bony support structure of the forearm. The radius plays a key role in the elbow joint, wrist joint, and forearm rotation movement and is an important part of the upper limb function. When people exercise, due to carelessness or falling, etc., it is easy to cause a radius fracture, and at this time, a steel plate is needed to fix the radius fracture.

[0003] A prior utility model patent with the authorized publication number: CN209450632U discloses "a palmar locking fixator for the distal radius, including a fixing plate. The fixing plate is a steel plate with a smooth arc chamfer at the edge. The fixing plate includes a palmar part plate and a shaft part plate. The palmar part plate is a curved arc steel plate. There is a curved arc transition part between one end of the palmar part plate and one end of the shaft part plate and they are transitionally connected through the curved arc transition part. The curved arc transition part, the middle part of the palmar part plate, and the other end of the shaft part plate are respectively provided with arc-shaped holes. The middle part of the shaft part plate is provided with an adjustment long hole. The palmar part plate and the shaft part plate are both provided with a number of locking screw holes and Kirschner wire holes. The present invention can fit the human bone and can perform fine adjustment of the position and angle after connection."

[0004] The above solution usually can only fit one side of the human bone, that is, the side of the radius. However, in the case of a more severe fracture, the side of the radius close to the palmar side may split into multiple pieces. In this way, if only one side of the radius is fixed, the split radius may also leak out from both sides of the fixing plate, thus easily affecting the normal recovery of the radius. Summary of the Invention

[0005] The present invention provides a palmar locking plate fixation mechanism to solve the technical problem that in the related art, if only one side of the radius is fixed, the split radius may also leak out from both sides of the fixing plate, thus easily affecting the normal recovery of the radius.

[0006] The present invention provides a palmar locking plate fixing mechanism, including: a locking plate, which includes: a plate head, a plate body, a plurality of first arc-shaped plates and a plurality of second arc-shaped plates. The plate head is fixedly connected to the plate body, and fixing holes are provided on both the plate head and the plate body.

[0020] Now, the subject matter described herein will be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the protection scope of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0021] As Figures 1 - 9 shown, a volar locking plate fixing mechanism includes: a locking plate 1 and a plurality of driving components 2. The locking plate 1 is mainly used to fix the radius, facilitating the recovery of the radius. The driving component 2 is mainly used to provide power for the movement of corresponding components.

[0022] Specifically, as Figure 1 shown, the locking plate 1 includes: a plate head 11, a plate body 12, a plurality of first arc - shaped plates 13, and a plurality of second arc - shaped plates 14. Among them, one side of the plate head 11 is fixedly connected to one side of the plate body 12. The structures of the plate head 11 and the plate body 12 are similar to the structure of an adjustable wrench, and the plate head 11 is similar to the head position of an adjustable wrench. Since the width of the radius near the volar side is wider than the width of the radius far from the volar side, when in use, the plate head 11 can be arranged close to the volar side, so as to better adapt to the shape of the radius, and thus can fix a larger area of the position of the radius near the volar side.

[0023] Further, fixing holes 15 are provided on both the head 11 and the body 12 of the plate. The fixing holes 15 mainly play a role in fixing. During use, first use a drilling tool to drill holes in the radius, and then use screws to fixedly connect the head 11 and the body 12 to the radius through the fixing holes 15, so that the head 11 and the body 12 can better fix the radius, which is beneficial to the recovery of the radius.

[0024] In addition, as Figures 1 - 3 shown, a plurality of first arc-shaped plates 13 and a plurality of second arc-shaped plates 14 are respectively slidably arranged on both sides of the body 12 of the plate. The first arc-shaped plates 13 and the second arc-shaped plates 14 mainly play a role in fixing both sides of the radius. Since the width of the radius varies in its length direction, a plurality of first arc-shaped plates 13 and a plurality of second arc-shaped plates 14 are provided, and the plurality of first arc-shaped plates 13 and the plurality of second arc-shaped plates 14 are distributed along the length direction of the radius. In this way, the distance between each first arc-shaped plate 13 and the body 12, that is, the distance from the side of the radius, can be freely adjusted, so that the plurality of first arc-shaped plates 13 and the plurality of second arc-shaped plates 14 can be more closely arranged along the side of the radius, thereby better fixing the side of the radius and reducing the situation where the fracture of the radius leaks out from both sides of the body 12 and the head 11. In addition, the slidable arrangement of the plurality of first arc-shaped plates 13 and the plurality of second arc-shaped plates 14 can also be suitable for the use of radii of different sizes of various people, and the use is more flexible and convenient.

[0025] In addition, as Figure 4 and Figure 5 shown, the number of the plurality of driving components 2 is the same as the total number of the first arc-shaped plates 13 and the second arc-shaped plates 14, and the plurality of driving components 2 correspond to the first arc-shaped plates 13 and the second arc-shaped plates 14 one by one. The plurality of driving components 2 are used to adjust the distance between the corresponding first arc-shaped plate 13 or second arc-shaped plate 14 and the body 12. That is to say, each first arc-shaped plate 13 and each second arc-shaped plate 14 correspond to one driving component 2, so that it is convenient to adjust each first arc-shaped plate 13 and each second arc-shaped plate 14, and the use is more flexible and convenient.

[0026] Specifically, as Figure 4 and Figure 5As shown, an installation groove 121 is formed on the side wall of the plate body 12 away from the radius. The installation groove 121 is provided on the side of the plate body 12 away from the radius, which is convenient for medical staff to observe and operate. The installation groove 121 mainly plays a role in installation. The driving component 2 includes a screw rod 21 and a hexagonal fixing seat 22. The screw rod 21 is threadedly connected to the plate body 12, and one end of the screw rod 21 is rotatably connected to the corresponding first arc-shaped plate 13 or the second arc-shaped plate 14. The other end of the screw rod 21 extends into the installation groove 121 and is fixedly connected to the corresponding hexagonal fixing seat 22. It should be noted that the hexagonal fixing seat 22 can be a regular hexagonal fixing seat 22, which is convenient for installation and setting.

[0027] During use, when it is necessary to adjust the distance between a certain first arc-shaped plate 13 or the second arc-shaped plate 14 and the side of the radius, rotate the corresponding hexagonal fixing seat 22. The rotation of the hexagonal fixing seat 22 can drive the corresponding screw rod 21 to rotate. Since one end of the screw rod 21 is rotatably connected to the corresponding first arc-shaped plate 13 or the second arc-shaped plate 14, the corresponding first arc-shaped plate 13 or the second arc-shaped plate 14 can be controlled to move along the axial direction of the screw rod 21 until the inner wall of the corresponding first arc-shaped plate 13 or the second arc-shaped plate 14 fits against the side of the radius, so as to better fix the side of the radius, facilitate the recovery of the radius, and can also be applicable to radii of various sizes.

[0028] Furthermore, as Figure 1 and Figure 2 shown, the number of fixing holes 15 on the plate head 11 and the number of fixing holes 15 on the plate body 12 are both multiple, and two adjacent fixing holes 15 are arranged at intervals. Since the degree of splitting of the radius of different injured patients may be different, for minor splitting, a small number of screws can be used to fix the plate head 11 and the plate body 12, but for more serious radius splitting, more screws are needed to fix the plate head 11 and the plate body 12. Therefore, setting the number of fixing holes 15 on the plate head 11 and the plate body 12 to be multiple can better adapt to the radius splitting conditions of different injured patients. In addition, with multiple fixing holes 15, it is also possible to select the fixing holes 15 at appropriate positions for fixing the plate head 11 and the plate body 12 to the radius, making the use more flexible and convenient.

[0029] In addition, as Figure 2As shown in the figure, the fixing hole 15 includes: a rectangular hole 151 and two semi-circular holes 152. In the length direction of the rectangular hole 151, the two semi-circular holes 152 are arranged on both sides of the rectangular hole 151, and the two wide sides of the rectangular hole 151 are respectively collinear with the diameters of the two semi-circular holes 152. In the prior art, if the size and position of the holes drilled by medical staff on the radius bone exactly correspond to the size and position of the plate head 11 and the fixing hole 15, the plate body 12 and the plate head 11 can be fixed exactly. If the size and position of the holes drilled by medical staff on the radius bone deviate from the position of one or more fixing holes 15, it will be difficult to fix the plate body 12 and the plate head 11 well with the radius bone, and it may be necessary to drill holes again on the radius bone. Therefore, the fixing hole 15 is divided into a combination of two semi-circular holes 152 and a rectangular hole 151. That is to say, the size of the fixing hole 15 is larger than the diameter size of the threaded part on the corresponding screw, so that the screw can be adjusted in position on the fixing hole 15. Even if there are slight errors in the size and position of the holes drilled by medical staff on the radius bone, it will not affect the fixation between the plate body 12 and the plate head 11 and the radius bone. It should be noted that the size of the fixing hole 15 is smaller than the size of the screw head. To avoid the situation where the head of the screw directly passes through the fixing hole 15.

[0030] In addition, as Figure 7 shown, on the side of the plate body 12 facing the first arc-shaped plate 13, a first annular groove 122 is provided, and on the side of the first arc-shaped plate 13 facing the plate body 12, a first annular plate 131 is fixedly connected. The first annular plate 131 is slidably connected with the first annular groove 122. Among them, the first annular plate 131 mainly plays a role in protection and guidance. Since the first annular plate 131 is slidably connected with the first annular groove 122, when the screw rod 21 drives the corresponding first arc-shaped plate 13 to move, the first annular plate 131 can keep the first arc-shaped plate 13 moving along the axial direction of the screw rod 21, avoiding the situation where the first arc-shaped plate 13 rotates together with the screw rod 21, so that the movement of the first arc-shaped plate 13 can be more stable. Moreover, the annular structure design of the first annular plate 131 can seal and protect the part of the screw rod 21 located between the plate body 12 and the corresponding first arc-shaped plate 13, reducing the contact between the screw rod 21 and the skin tissue.

[0031] Similarly, as Figure 8As shown, on one side of the plate body 12 facing the second arc-shaped plate 14, a second annular groove 123 is provided. On one side of the second arc-shaped plate 14 facing the plate body 12, a second annular plate 141 is provided, and the second annular plate 141 is slidably connected to the second annular groove 123. Among them, the second annular plate also mainly plays a role in protection and guidance. Since the second annular plate 141 is slidably connected to the second annular groove 123, when the screw 21 drives the corresponding second arc-shaped plate 14 to move, the second annular plate 141 can keep the second arc-shaped plate 14 moving along the axial direction of the screw 21, avoiding the situation that the second arc-shaped plate 14 rotates together with the screw 21, so that the movement of the second arc-shaped plate 14 can be more stable. Moreover, the annular structure design of the second annular plate 141 can seal and protect the part of the screw 21 between the plate body 12 and the corresponding second arc-shaped plate 14, reducing the contact between the screw 21 and the skin tissue.

[0032] As an optional embodiment, chamfered corners are provided on one side of the first arc-shaped plate 13 and the second arc-shaped plate 14 away from the plate body 12. The provision of the chamfered corners can reduce the frictional force between one side of the first arc-shaped plate 13 and the second arc-shaped plate 14 away from the plate body 12 and the skin tissue, which is beneficial to protecting the human body during the installation process of the first arc-shaped plate 13 and the second arc-shaped plate 14.

[0033] Furthermore, as Figure 2 shown, the fixed mechanism of the palmar locking plate 1 further includes: a sealing plate 3, and the sealing plate 3 is fixedly connected to the plate body 12 to seal the installation groove 121. Among them, the sealing plate 3 mainly plays a sealing role. The sealing plate 3 is fixed to the plate body 12 by screws, so as to achieve the sealing of the installation groove 121. During use, when the positions of the plate body 12, the plate head 11, the first arc-shaped plate 13 and the second arc-shaped plate 14 are all adjusted, the sealing plate 3 is fixedly connected to the plate body 12 by screws to seal the installation groove 121, so that the hexagonal fixing seat 22 and the screw 21 inside the installation groove 121 can be isolated from the external environment, thereby reducing the damage to the human body and also protecting the hexagonal fixing seat 22 and the screw 21 inside the installation groove 121.

[0034] In addition, the plurality of first arc-shaped plates 13 are arranged at intervals, and the plurality of second arc-shaped plates 14 are arranged at intervals. The plurality of first arc-shaped plates 13 are arranged at intervals, and the plurality of second arc-shaped plates 14 are arranged at intervals, so that when the screw 21 drives the corresponding first arc-shaped plate 13 and second arc-shaped plate 14 to move, interference between adjacent first arc-shaped plates 13 and adjacent second arc-shaped plates 14 can be avoided, facilitating the movement of the first arc-shaped plate 13 and the second arc-shaped plate 14.

[0035] In addition, as Figure 4 and Figure 6As shown, the hexagonal fixing base 22 is provided with through holes 221 penetrating through each corner. The palmar locking plate 1 fixing mechanism further includes: a plurality of safety ropes 4. In the final state of the hexagonal fixing base 22, for two adjacent hexagonal fixing bases 22 on the same side, one end of the safety rope 4 is fixedly connected to the upper through hole 221 of one of the hexagonal fixing bases 22, and the other end of the safety rope 4 is fixedly connected to the lower through hole 221 of the other hexagonal fixing base 22. For the case where two safety ropes 4 are fixedly connected to the same hexagonal fixing base 22, both safety ropes 4 are fixedly connected to the upper side or the lower side of the corresponding hexagonal fixing base 22.

[0036] For example, taking Figure 6 as an example, counting from left to right, an upper through hole 221 of the first hexagonal fixing base 22 is fixedly connected to a lower through hole 221 of the second hexagonal fixing base 22 through a safety rope 4, and another lower through hole 221 of the second hexagonal fixing base 22 is fixedly connected to an upper through hole 221 of the third hexagonal fixing base 22 through another safety rope 4, and so on, to complete the connection between all the hexagonal fixing bases 22 on one side. Since the safety rope 4 can only transmit tensile force and cannot transmit thrust, the safety rope 4 between the first hexagonal fixing base 22 and the second hexagonal fixing base 22 has a clockwise tensile force on the second hexagonal fixing base 22, and the safety rope 4 between the second hexagonal fixing base 22 and the third hexagonal fixing base 22 has a counterclockwise tensile force on the second hexagonal fixing base 22. Therefore, the relative stability of the second hexagonal fixing base 22 can be maintained, the situation of the second hexagonal fixing base 22 rotating freely can be reduced, and thus the relative stability of the corresponding first arc plate 13 can be maintained. And so on, thereby the relative stability of the positions of the overall first arc plate 13 and the second arc plate 14 can be maintained.

[0037] The above has described the embodiments of this example, but this example is not limited to the above specific implementation manners. The above specific implementation manners are only illustrative and not restrictive. Under the inspiration of this example, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this example.
