[0002] like Figure 1 As shown, the sternum plates on the market are basically integrated with the left plate and the right plate. When an emergency requires thoracotomy, all the screws must be unscrewed before the locking plate is removed, which greatly increases the operation time. Utility Model Content

[0003] The purpose of the utility model is to provide a split sternum plate which is detachable and adopts pull-out pins. In an emergency, the plate can be quickly pulled out to separate the left and right plates and open the chest cavity.

[0004] An embodiment of the present application discloses a split sternum plate, including a left plate body and a right plate body, the left plate body including two left nail plates arranged up and down on the left side, the right plate body including two right nail plates arranged up and down on the right side, the right sides of the left plate body protrude to the right from the upper and lower sides respectively to form two left support plates, the left side of the right plate body protrudes to the left to form a right support plate, the right support plate is fitly inserted into the interval space formed between the two left support plates, and also includes a U-shaped pin, the two arms of the U-shaped pin are inserted from top to bottom and connect the left support plate and the right support plate, and one arm of the U-shaped pin is thinned near the bottom.

[0005] Preferably, in the above-mentioned split sternum plate, a left positioning hole is formed on the side surface of the left support plate and fits with the U-shaped pin.

[0006] Preferably, in the above-mentioned split sternum plate, a right positioning hole is formed on the side surface of the right support plate and fits with the U-shaped pin.

[0007] Preferably, in the above-mentioned split sternum plate, a left nail hole is formed on the surface of the left nail plate, and a right nail hole is formed on the surface of the right nail plate.

[0008] Preferably, in the above-mentioned split sternum plate, the top surfaces of the left nail plate and the right nail plate are inclined surfaces.

[0009] Preferably, in the above-mentioned split sternum plate, a left blood supply groove is formed between the left nail plate and the back surface of the left support plate.

[0010] Preferably, in the above-mentioned split sternum plate, a right blood supply groove is formed between the right nail plate and the back surface of the right support plate.

[0011] Preferably, in the above-mentioned split sternum plate, the upper portion of the U-shaped pin is bent to one side.

[0012] Compared with the existing technology, the advantage of this technical solution is that it adopts a detachable and removable pin, which can be quickly pulled out in an emergency to separate the left and right plates and open the chest cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a detailed description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Combine Figures 1-6As shown, the split sternum plate 100 includes a left plate body 101 and a right plate body 102. The left plate body 101 includes two left nail plates 103 arranged on the upper and lower sides of the left side, and the right plate body 102 includes two right nail plates 104 arranged on the upper and lower sides of the right side. The right side of the left plate body 101 extends rightward to form two left support plates 105, and the left side of the right plate body 102 extends leftward to form a right support plate 106. The right support plate 106 fits snugly into the space 107 formed between the two left support plates 105. The right support plate 106 also includes a U-shaped pin 108. The two arms of the U-shaped pin 108 are inserted from top to bottom to connect the left support plate 105 and the right support plate 106. One arm of the U-shaped pin 108 is thinned near the bottom. The side of the left support plate 105 is formed with a left positioning hole 109 that fits snugly with the U-shaped pin 108. The side of the right support plate 106 is formed with a right positioning hole 110 that fits into the U-shaped pin 108. The left nail plate 103 is formed with a left nail hole 111, and the right nail plate 104 is formed with a right nail hole 112. The top surfaces of the left and right nail plates 103 and 104 are inclined surfaces 113. A left blood supply groove 114 is formed between the left nail plate 103 and the back of the left support plate 105. A right blood supply groove 115 is formed between the right nail plate 104 and the back of the right support plate 106. The upper portion of the U-shaped pin 108 is bent to one side.

[0022] This embodiment utilizes a removable and removable pin, allowing for quick removal in an emergency, separating the left and right plates and opening the chest cavity. The back blood supply groove facilitates blood flow and promotes bone healing; the beveled surface reduces soft tissue irritation; the chamfered corners provide a smoother, rounder design; the chamfered opening facilitates pin insertion; the wide-opening design of the spacer facilitates assembly; the U-shaped pin is thinned at one point for smoother insertion and can be gently bent at the end of the procedure to prevent it from falling out; and the pin's bend design makes it easier to handle while limiting insertion depth.

[0023] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0024] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
