1 to 4, a plate unit 1 according to an embodiment of the present invention includes a plate unit 1 for joining a part of a fractured bone when a part of a bone of the human body is fractured, It can be used fixedly on the pubic part of the human body especially when the pubic bone or the symphysis pubis is fractured. 1 and 2 illustrate that the plate unit 1 according to the embodiment is fixed to a part of the bones of the pelvis, but the present invention is not limited thereto. For example, the plate unit 1 may be fixedly used on a part of a bone, such as a knee joint, an elbow joint, an ankle joint, a tibia, or the like. Hereinafter, the plate unit 1 will be exemplarily described as being fixed to a part P1 or P2 of the pelvis P. FIG. The plate unit 1 according to one embodiment may include a plate member 11, a binding member 12, a wire 13, a guide member 14, a spike member 15 and a clip member 16 have.

The plate member 11 can be fixedly used on the fractured portion of the pelvis P. [ The plate member 11 may include an upper surface, a lower surface, at least two or more bone fixing areas 111 and 112, and a bridge area 113.

At least two or more bone fixation regions 111 and 112 may include a first bone fixation region 111 and a second bone fixation region 112. The first bone fixation region 111 may be fixed to the first portion Pl of the pelvis P. [ The first bone fixation region 111 may include at least one through hole 1111 in which a thread is formed on the inner wall. The through holes 1111 may be formed in the first bone fixing region 111 by spacing at least one of the through holes 1111 along the longitudinal direction of the plate member 11. The second bone fixation region 112 may include at least one through hole 1121 that may be fixed to the second portion P2 of the pelvis P and formed with a thread on the inner wall.

The bridge region 113 may be disposed between at least two or more bone fixation regions 111 and 112 and may connect at least two or more bone fixation regions 111 and 112. The bridge region 113 may be located at the fractured portion between the first portion P1 and the second portion P2. The force can be evenly distributed to at least two bone fixation regions 111 and 112 based on the fractured portion.

The binding member 12 can bind at least two or more bone fixing regions 111 and 112 to the portions P1 and P2 of the pelvis P. [ For this purpose, the binding member 12 may be disposed through at least one through hole 1111, 1121 of each of the at least two bone fixing regions 111, 112. For example, the binding member 12 may be a screw used in the clinical field and may perform a locking function so that at least two or more bone fixation regions 111 and 112 may extend from the pelvis P Can be prevented from being separated.

The wire 13 can form a loop along the periphery of the pelvis P and the bridge region 113 and can firmly fix the plate member 11 to the pelvis P. [ According to this structure, it is possible to prevent the plate member 11 from being separated from the pelvis P and to prevent the plate member 11 from being damaged. In other words, it is possible to prevent or reduce complications that may occur when the plate member 11 is broken or separated from the pelvis P in the case where a disease such as a pubic bone fracture or a pubic bone fracture occurs in the human body.

The wire 13 extends from one side of the bridge region 113 to the other side of the bridge region 113 and surrounds the periphery of the second portion P2 of the pelvis P and extends from the other side of the bridge region 113 A loop may be formed to wrap around the first portion P1 of the pelvis P across the one side of the bridge region 113. [ According to this structure, an elastic action can be provided between the plate member 11 and the pelvis P, thereby preventing excessive force from acting on the pelvis P from the plate member 11, It is possible to prevent breakage of the pelvis 11 and breakage of the pelvis P. When the plate member 11 is about to be separated from the pelvis P, So that it can be fixed.

The guide member 14 can guide the direction of the binding member 12 toward the pelvis P. [ The guide member 14 can be connected to the plate member 11 adjacent to the pelvis P and connected to the groove of the binding member 12 (having a hexagonal shape) to adjust the direction of the binding member 12 . According to this structure, even if the surgeon does not have a lot of surgical experience and the insertion of the binding member 12 into the pelvis P is immature, the surgeon can orient the binding member 12 guided by the guide member 14 The binding member 12 can be easily disposed through at least one through hole 1111 and 1121. [

The spike member 15 can be fixed to the portions P1 and P2 of the pelvis P. [ The spike member 15 may be formed on the lower surface of the plate member 11. According to this structure, even if an external force is applied to the plate member 11 by fixing the spike member 15 to the portions P1 and P2 of the pelvis P, the plate member 11 is detached from the pelvis P, Can be prevented.

The clip member 16 can be fixed to the portions P1 and P2 of the pelvis P. [ The clip member 16 may include a clip body 161, a clip blade 162, and a rivet 163. [ The clip main body 161 includes at least two bone fixing areas 111 and 112 and specifically a first attachment part 1112 of the first bone fixing area 111 and a second attachment part 1112 of the second bone fixing area 112. [ 2 attaching portion 1122 of the main body 1110. [ The clip wing 162 can extend from the clip body 161. Fig. For example, the clip blade 162 may extend in a direction (or a radial direction) crossing the longitudinal direction (or the circumferential direction) of the plate member 11. The rivets 163 are engaged with the clip body 161 and / or the second attachment portion 1112 through the first fastener 1113 and / or the second fastener 1123 toward the first attachment portion 1112 and / Can be combined. According to this structure, the plate member 11 can be prevented from being slipped or separated in the direction crossing the longitudinal direction, and the plate member 11 can be stably fixed to the pelvis P.

The plate member 11 may further include a slit 1131. The slit 1131 is formed in the bridge region 113 and can receive the wire 13. The slit 1131 may be formed in the bridge region 113 from one side of the bridge region 113 to the other side of the bridge region 113 and may extend from the other side of the bridge region 113 to the bridge region 113, And may be formed in the bridge region 113 across one side of the bridge region 113. In other words, the slit 1131 can be formed in the bridge region 113 in an 'X' shape. According to this structure, the wire 13 can be fixed in tight contact with the plate member 11 to form a loop, thereby preventing the wire 13 from being detached from the plate member 11. In addition, since a surgeon such as a doctor can easily form a loop between the plate member 11 and the pelvis P during wire operation, the operation can be simplified.
