Technical Field

[0001] The invention relates to the technical field of fracture treatment, in particular to a proximal humeral fracture reduction guide. Background Art

[0002] Proximal humeral fractures often refer to surgical neck fractures of the humerus. During surgery, the fracture needs to be repositioned and then the main nail is driven in. In actual operations, multiple positioning pins need to be driven in. During the driving process, the positioning pins are prone to dislocation, resulting in abnormal healing of the fracture. Doctors then need to drive in the pins a second time, which greatly causes secondary damage to the patient and is not conducive to treatment. Summary of the invention

[0024] Now, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] A proximal humeral fracture reduction guide, such as Figures 1 to 6 As shown, it includes a main board 1, a first side board 2, a second side board 3, and a top board 4.

[0026] The main board 1 is provided with a plurality of main holes 101, and the main holes 101 are used for placing the resetting steel needles.

[0027] The first side plate 2 is provided with a plurality of first side holes 201 , and the second side plate 3 is provided with a plurality of second side holes 301 . The first side holes 201 and the second side holes 301 are used for placing reduction needles.

[0028] The second side plate 3 and the first side plate 2 are respectively arranged on both sides of the main plate 1 and are in an inverted eight shape, and the axes of the first side hole 201, the second side hole 301 and the main hole 101 are not on the same plane. The shapes of the main plate 1, the first side plate 2 and the second side plate 3 are similar to a flying bird folding its wings. The first side hole 201 and the second side hole 301 are respectively arranged on the first side plate 2 and the second side plate 3.

[0029] The top plate 4 is provided with a plurality of top holes 401 . The top plate 4 is arranged at the top end of the main plate 1 . The top holes 401 are used to pass the guide pins.

[0030] When in use, the reduction guide is first placed on the proximal humeral fracture for preliminary positioning, and then a reduction steel needle is driven into the main hole 101, and the reduction steel needle is located at the normal bone of the humerus. Then, the fracture is pricked up with the reduction guide for preliminary positioning; the reduction guide is fixed on the humerus, and then the reduction steel needles are respectively driven into the first side hole 201 and the second side hole 301, so that the reduction steel needles are inserted into the bone to complete the positioning (the side plate may not be in contact with the patient, but it does not affect the operation and use). The three reduction steel needles that are not in the same plane allow the proximal humeral fracture to be accurately positioned. Then, a guide needle is driven into the top hole 401, the reduction guide is withdrawn, and finally the main nail is driven in along the guide needle.

[0031] Regarding how the main nail can accurately connect the fracture, it is necessary to

[0032] Making predictions based on practical experience is an easy thing for doctors who have been engaged in humeral surgery for many years.

[0033] In order to facilitate the initial positioning of the main nail, an auxiliary plate 5 is designed. The auxiliary plate 5 is arranged at the bottom end of the main plate 1. The auxiliary plate 5 is provided with a fixing hole 501, which can be used to bind the reset guide.

[0034] In order to facilitate the patient's later life, the size of the installer should be minimized as much as possible. The main hole 101 is used to insert and position the reset needle, so the main holes 101 are staggered in sequence, that is, two adjacent main holes 101 are connected.

[0035] The first side hole 201 and the second side hole 301 are also used to insert the reduction needle, but the insertion position of the reduction needle cannot be predicted in advance, and the angle needs to be selected according to the actual situation, so the first side hole 201 forms a first strip groove, and the second side hole 301 forms a second strip groove. The strip groove can be imagined as a combination of multiple side holes slapped in a row.

[0036] The reset steel needle can be at a certain angle in the strip groove, as long as it is in this groove. At this time, the first strip groove is a side opening groove, and the second strip groove is a side opening groove, which can greatly improve the installation efficiency.

[0037] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, as long as there is no structural conflict, the technical solutions recorded in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
