技术领域Technical Field
本实用新型属于创伤骨科骨折治疗内固定技术领域，具体是涉及一种肱骨接骨锁定板。The utility model belongs to the technical field of internal fixation for traumatic orthopedic fracture treatment, and in particular relates to a humeral bone-setting locking plate.
背景技术Background Art
肱骨上端由肱骨头、肱骨颈、大结节和小结节组成。外科颈是肱骨的常见骨折部位。肱骨近端骨折包括肱骨外科颈在内，及其以上部位的肱骨骨折。肱骨近端骨折是临床常见的肩部创伤性疾病。肱骨近端骨折发生率约占全身骨折的4-5％。年龄>60岁的患者比例超过70％。对于位移不稳定的骨折目前多采用肱骨近端锁定钢板固定。The upper end of the humerus is composed of the humeral head, humeral neck, greater tuberosity and lesser tuberosity. The surgical neck is a common fracture site of the humerus. Proximal humeral fractures include the surgical neck of the humerus and humeral fractures above it. Proximal humeral fractures are common traumatic shoulder diseases in clinical practice. The incidence of proximal humeral fractures accounts for about 4-5% of all fractures in the body. The proportion of patients aged >60 years old exceeds 70%. For unstable fractures with displacement, proximal humeral locking plates are currently used for fixation.
部分非降解材料的肱骨近端锁定钢板在植入人体后，常会引起一系列机体反应，需要通过外部持续服药进行免疫抵抗或二次手术将其取出，这增加了患者痛苦和医疗费用，也提高了二次感染率。不仅如此，非降解金属植入物弹性模量远大于人骨弹性模量，因而常导致患处应力遮挡，引发骨质疏松、骨溶解及二次骨折。Some non-degradable proximal humeral locking plates often cause a series of body reactions after being implanted in the human body, requiring continuous external medication for immune resistance or secondary surgery to remove them, which increases the patient's pain and medical expenses, and also increases the secondary infection rate. In addition, the elastic modulus of non-degradable metal implants is much greater than that of human bones, which often leads to stress shielding of the affected area, causing osteoporosis, osteolysis and secondary fractures.
近年来，传统锁定钢板治疗肱骨近端骨折中所产生一系列肱骨头内翻位移、内固定失败、螺钉穿出肱骨头关节面，肩峰下撞击症及肱骨头坏死等并发症，需要针对骨折类型对肱骨近端锁定骨板进行结构设计优化。In recent years, a series of complications such as varus displacement of the humeral head, internal fixation failure, screw penetration of the humeral head articular surface, subacromial impingement and humeral head necrosis have occurred in the treatment of proximal humeral fractures with traditional locking plates. It is necessary to optimize the structural design of the proximal humeral locking plate according to the fracture type.
为此，提出一种肱骨接骨锁定板。To this end, a humeral osteosynthesis locking plate is proposed.

实施例Example
本实施例提供的肱骨接骨锁定板，如图1-图6所示，包括：可降解镁合金材料制成的肱骨近端锁定接骨板，肱骨近端锁定接骨板包括能够包围固定在大结节靠近肩峰的头部1以及能够固定在外科颈和肱骨体的干部2。The humeral locking plate provided in this embodiment, as shown in Figures 1 to 6, includes: a proximal humeral locking plate made of a degradable magnesium alloy material, the proximal humeral locking plate including a head 1 that can be surrounded and fixed on the greater tuberosity near the acromion and a stem 2 that can be fixed on the surgical neck and the humeral body.
其中，头部1包括与大结节接触的第一表面101以及与第一表面101相对设置的第二表面102；The head 1 includes a first surface 101 in contact with the greater tubercle and a second surface 102 arranged opposite to the first surface 101;
其中，干部2包括与外科颈和公估体面接触的第三表面201以及与第三表面201相对设置的第四表面202；The trunk 2 includes a third surface 201 in contact with the surgical neck and the body surface, and a fourth surface 202 arranged opposite to the third surface 201;
其中，第一表面101与第三表面201相连，第二表面102与第四表面202相连；The first surface 101 is connected to the third surface 201, and the second surface 102 is connected to the fourth surface 202;
其中，头部1设置八个锁定孔A3，锁定孔A3从第一表面101延伸到第二表面102，且锁定孔A3靠近肩峰；The head 1 is provided with eight locking holes A3, which extend from the first surface 101 to the second surface 102, and the locking holes A3 are close to the acromion;
其中，干部2设置四个锁定孔B4，锁定孔B4从第三表面201延伸到第四表面202，且锁定孔B4靠近内侧缘。The trunk 2 is provided with four locking holes B4 , which extend from the third surface 201 to the fourth surface 202 , and are close to the inner edge.
具体的，在本实施例中，第一表面101和第三表面201在肱骨近端大结节及外科颈肱骨体延伸，其总长度不能大于肩峰到肱骨体远端的长度，肱骨近端锁定接骨板为一体设计，且肱骨近端锁定接骨板的头部1为解剖型圆弧面。Specifically, in this embodiment, the first surface 101 and the third surface 201 extend at the greater tuberosity of the proximal humerus and the surgical neck of the humerus, and their total length cannot be greater than the length from the acromion to the distal end of the humeral body. The proximal humeral locking plate is an integrated design, and the head 1 of the proximal humeral locking plate is an anatomical arc surface.
具体的，在本实施例中，肱骨近端锁定接骨板的头部1靠近肩峰的一端设置有弧度削减厚度，整体呈圆弧扇形对大结节及周边肱骨头进行包裹形态。Specifically, in the present embodiment, the head 1 of the proximal humeral locking plate is provided with an arc-shaped thickness reduction at one end close to the acromion, and the whole is in a circular arc fan shape to wrap the greater tuberosity and the surrounding humeral head.
具体的，在本实施例中，肱骨近端锁定接骨板需符合肱骨近端位置的解剖形态，在此基础上，按解剖形态设计有头部1与干部2的圆弧过度，即头部1与干部2曲律需参照国人肱骨解剖形态设计。Specifically, in this embodiment, the proximal humeral locking plate needs to conform to the anatomical morphology of the proximal humerus. On this basis, a circular arc transition between the head 1 and the trunk 2 is designed according to the anatomical morphology, that is, the curvature of the head 1 and the trunk 2 needs to be designed with reference to the anatomical morphology of the Chinese humerus.
由于肱骨近端锁定接骨板是解剖型接骨板，因此，其头部1与干部2不在同一平面上，其具有一定程度的曲率过渡，曲率大小由国人肱骨解剖的形态决定，选取大量肱骨模型进行曲面提取优化，得出最符合大众的肱骨表面曲率。Since the proximal humeral locking plate is an anatomical plate, its head 1 and shaft 2 are not on the same plane, and it has a certain degree of curvature transition. The size of the curvature is determined by the anatomical morphology of the Chinese humerus. A large number of humeral models are selected for surface extraction and optimization to obtain the humeral surface curvature that best suits the public.
具体的，在本实施例中，头部1宽度尺寸大于干部2宽度尺寸，此设计使得肱骨近端锁定接骨板在肱骨近端固定更稳定，固定强度更强。Specifically, in the present embodiment, the width of the head 1 is greater than the width of the trunk 2. This design enables the proximal humeral locking plate to be more stably fixed to the proximal humerus and has a stronger fixation strength.
具体的，在本实施例中，八个锁定孔A3分别为第一锁定孔A301、第二锁定孔A302、第三锁定孔A303、第四锁定孔A304、第五锁定孔A305、第六锁定孔A306、第七锁定孔A307以及第八锁定孔A308，第一锁定孔A301孔向以及第二锁定孔A302孔向呈放射状靠近肩峰位置，第三锁定孔A303孔向以及第四锁定孔A304孔向较第一锁定孔A301以及第二锁定孔A302稍低位置更为发散，第五锁定孔A305孔向以及第六锁定孔A306孔向呈交叉状，第七锁定孔A307孔向以及第八锁定孔A308孔向同时打入肱骨距位置。Specifically, in the present embodiment, the eight locking holes A3 are respectively the first locking hole A301, the second locking hole A302, the third locking hole A303, the fourth locking hole A304, the fifth locking hole A305, the sixth locking hole A306, the seventh locking hole A307 and the eighth locking hole A308. The first locking hole A301 and the second locking hole A302 are radially close to the acromion position, the third locking hole A303 and the fourth locking hole A304 are more divergent at a slightly lower position than the first locking hole A301 and the second locking hole A302, the fifth locking hole A305 and the sixth locking hole A306 are cross-shaped, and the seventh locking hole A307 and the eighth locking hole A308 are simultaneously driven into the calcar position.
上述设计，使得肱骨近端锁定接骨板与螺钉配合后，锁定更稳固，且不易旋转，不易与肱骨近端的碎骨块脱离。The above design makes the locking of the proximal humerus locking bone plate and the screw more stable and not easy to rotate or separate from the proximal humerus bone fragments after the proximal humerus locking bone plate and the screw are matched.
具体的，在本实施例中，八个锁定孔A3以及四个锁定孔B4均为螺纹孔，在手术中医生可在多个方位实现对螺钉的紧固定，方便进钉。Specifically, in the present embodiment, the eight locking holes A3 and the four locking holes B4 are all threaded holes, and during the operation, the doctor can achieve tight fixation of the screws in multiple positions to facilitate screw insertion.
具体的，在本实施例中，八个锁定孔A3内均安装有第一螺钉5，四个锁定孔B4内均安装有第二螺钉6，第一螺钉5以及第二螺钉6均采用低切迹设计，该设计可以降低锁定板对肱骨近端的软组织激惹，可减轻患者痛苦，更利于术后恢复。Specifically, in this embodiment, a first screw 5 is installed in each of the eight locking holes A3, and a second screw 6 is installed in each of the four locking holes B4. The first screw 5 and the second screw 6 both adopt a low-profile design, which can reduce the irritation of the locking plate to the soft tissue of the proximal humerus, alleviate the patient's pain, and be more conducive to postoperative recovery.
具体的，在本实施例中，设置的第一螺钉5以及第二螺钉6以及肱骨近端锁定接骨板均采用WE43镁合金材料制成，材质WE43镁合金材料，其组织相容性好，反应少，可降低感染率，且可在人体内自行降解无需二次手术取出。Specifically, in this embodiment, the first screw 5, the second screw 6 and the proximal humeral locking plate are all made of WE43 magnesium alloy material. The material WE43 magnesium alloy has good tissue compatibility, less reaction, can reduce the infection rate, and can be self-degraded in the human body without the need for secondary surgery to remove.
具体的，在本实施例中，设置的干部2为长弧状，四个锁定孔B4沿其中心轴设置，相邻的锁定孔B4之间间隔相同，上述设计，使得肱骨近端锁定接骨板与螺钉配合后，锁定更稳固，且不易旋转，不易与肱骨体脱离。Specifically, in this embodiment, the trunk 2 is arranged in a long arc shape, and four locking holes B4 are arranged along its central axis. The adjacent locking holes B4 are spaced the same distance apart. The above design makes the locking of the proximal humeral locking plate more stable after being matched with the screw, and is not easy to rotate or separate from the humeral body.
具体的，在本实施例中，设置的第一表面101与第二表面102及第三表面201和第四表面202通过侧面圆滑过渡连接，上述设计，使得肱骨近端锁定接骨板的设计符合人体工学设计，符合临床使用要求。Specifically, in this embodiment, the first surface 101 and the second surface 102 and the third surface 201 and the fourth surface 202 are connected by smooth side transitions. The above design makes the design of the proximal humeral locking plate ergonomic and meets clinical use requirements.
具体的，在本实施例中，设置的肱骨近端锁定接骨板厚度为1.3-5.5mm，上述设计，减小了患者的不适及对周围组织的激惹。Specifically, in the present embodiment, the thickness of the proximal humeral locking bone plate is 1.3-5.5 mm. The above design reduces the discomfort of the patient and the irritation to the surrounding tissues.
具体的，在本实施例中，在头部1与干部2的交界处开设有腰形孔7，腰形孔7用于定位，方便配合定位器械打入头部1位置的第一螺钉5。Specifically, in this embodiment, a waist-shaped hole 7 is provided at the junction of the head 1 and the trunk 2 , and the waist-shaped hole 7 is used for positioning, so as to facilitate the first screw 5 driven into the position of the head 1 with the cooperation of a positioning device.
综上，本实施例提供的肱骨接骨锁定板，具有如下优点：In summary, the humeral bone locking plate provided in this embodiment has the following advantages:
1.该肱骨接骨锁定板不易发生肩峰撞击；1. The humeral locking plate is not prone to shoulder impaction;
