Description

Electric nuss orthopedic plate shaping machine TECHNICAL FIELD

[0001] The present application relates to the technical field of implant processing, in particular to an electric Nuss orthopedic plate shaping machine. BACKGROUND

[0002] The Nuss operation is a Nuss minimally invasive operation for treating pectus excavatum (PECTUS EXCAVATUM, PE) announced by an American doctor Nuss in 1998. Pectus excavatum (PECTUS EXCAVATUM, PE) is a funnel-shaped deformity formed by the inward indentation of the middle and lower segments of the sternum and the adjacent costal cartilages, and the main feature is that the lower edge of the sternum to the xiphoid process is inclined and depressed to the dorsal side of the sternum, and the corresponding costal cartilages on both sides are also curved to the dorsal side, so that the lower part of the anterior chest wall is funnel-shaped, and the deepest point of the indentation is usually at the junction of the lower end of the sternum and the xiphoid process. The Nuss operation is to insert a Nuss orthopedic plate into the thoracic cavity under the guidance of a thoracoscope, to lift up the collapsed sternum, and the deformed costal cartilages on both sides are pushed outwards, and the Nuss orthopedic plate is fixed on both ends with a fixed crossbar with two holes on both sides, and the fixed crossbar is wound with a rib wire to fix it, so as to support the collapsed sternum, thereby achieving the purpose of chest wall orthopedics. After the implantation of the steel plate, the orthopedic effect is achieved as expected, and about two to three years after the thoracic shape is fixed, the orthopedic plate needs to be removed. The Nuss operation is a widely used orthopedic plate support operation for pectus excavatum in recent years.

[0003] In the prior art, before the operation, the Nuss orthopedic plate usually needs to be pre-bent according to the chest X-ray of the patient and the experience of the doctor, so that the Nuss orthopedic plate meets the needs of the patient's orthopedics. In order to realize the bending of the Nuss orthopedic plate, the bending forceps are usually used to realize this process in the prior art.

[0004] For example, Chinese patent CN201721284013.1 discloses a new type of special tool for minimally invasive treatment of chest wall deformity. It comprises a base and a stand rod arranged on the base, the stand rod is sequentially sleeved with a fixing assembly, a bending assembly and a bending ring from top to bottom, the fixing assembly and the bending assembly are arranged close to the top of the stand rod, and the bending ring is arranged close to the base. This scheme utilizes the cooperation of the fixing assembly, the bending assembly and the bending ring arranged on the stand rod, effectively realizes the functions of large bending angle, multiple bending styles and multiple bending numbers, and solves the technical problems existing in the existing bending forceps.

[0005] For example, Chinese patent CN201821588246.5 discloses a funnel chest correction steel plate shaping device, which comprises an arc-shaped main body, a steel plate clamping device and a shaping rod. Steel plate clamping devices are arranged at both ends of the arc-shaped main body. Each steel plate clamping device comprises a connecting shaft arranged on the arc-shaped main body, a sliding block in surface contact with the connecting shaft, a track groove arranged along the length direction of the sliding block and matched with the connecting shaft, a limiting nut arranged at the end of the connecting shaft away from the sliding block, a U-shaped clamping opening arranged at one end of the sliding block, a threaded fastener arranged at the opening end of the U-shaped clamping opening to press the steel plate, a shaping rod arranged at the center of the arc-shaped main body, a threaded connecting rod connected with the clamping rod through a bearing, and a U-shaped clamping frame arranged at the front end of the clamping rod. The opening end of the U-shaped clamping frame is provided with a limiting boss. In use, the shaping device is used as a mold. The orthopedic plate is placed in the arc-shaped main body and bent to the corresponding shape to realize the bending process of the orthopedic plate.

[0006] However, in actual implementation, the inventor found that in the application process of such technical solutions, although the principle of a lever is used to reduce the bending force, the doctor still needs to manually bend and shape with great effort, which is time-consuming and laborious.

[0071] To realize the pressing process of orthopedic plates of different sizes, the following two embodiments of orthopedic plate molds are provided in the scheme:

[0072] Embodiment one:

[0073] In one embodiment, as shown in FIG. 2, the orthopedic plate mold 3 includes a fixed mold 31 and a movable mold 32.

[0074] The fixed mold 31 is installed on the side of the fixed end 21 opposite to the movable end 22.

[0075] The movable mold 32 is installed on the side of the movable end 22 facing the fixed mold 31.

[0076] The side wall of the fixed end 21 is provided with a fixed mold sliding rail 211, and the fixed mold 31 is connected to the fixed end via the fixed mold sliding rail 211.

[0077] The side wall of the movable end 22 is provided with a movable mold sliding rail 221, and the movable mold 32 is connected to the movable end 22 via the movable mold sliding rail 212.

[0078] Specifically, to realize the pressing process of the Nuss orthopedic plate, the orthopedic plate mold 3 in the embodiment is divided into a fixed mold 31 and a movable mold 32, wherein the fixed mold 31 and the movable mold 32 are used as a male mold with a convex surface and a female mold with a concave surface respectively.

[0079] The side wall of the fixed end 21 is provided with a fixed mold sliding rail 211, and the side wall of the movable end 22 is provided with a movable mold sliding rail 221. The sliding rail is opened along the side wall direction and has a trapezoidal guide groove structure. Corresponding trapezoidal sliding blocks are processed at corresponding positions of the fixed mold 31 and the movable mold 32 respectively. The trapezoidal sliding blocks are drawn into the trapezoidal guide groove structure from one end, thereby realizing the replacement of the orthopedic plate mold 3.

[0080] According to the different curvatures of the Nuss orthopedic plate to be bent, a plurality of orthopedic plate molds 3 with different radii of curvature are designed in advance to replace them to match the processing requirements.

[0081] In addition, in order to achieve a better fixing effect, ball pin fixing devices are arranged between the fixed mold 31 and the fixed mold sliding rail 211 and between the movable mold 32 and the movable mold sliding rail 212, so as to lock the mold after the mold is slid into the guide rail to the position, avoiding slipping during the carrying process.

A recess is opened on the fixed mold 31 at a position corresponding to the ball head 53. When the fixed mold 31 is slid into the fixed mold sliding rail 211 and reaches the predetermined position, the ball head 53 will be embedded in the recess under the pushing of the ball pin spring 52. At the same time, the depth of the recess is less than the natural extension length of the ball head 53, so as to apply a certain pressure to the ball pin spring 52, thereby realizing the fixation of the fixed mold 31. When it is necessary to disassemble the fixed mold 31, the ball pin fixing screw 51 is loosened to reduce the pressure of the ball pin spring 52 or the ball head 53 is extracted in the opposite direction, so that the limiting of the fixed mold 31 disappears and the fixed mold 31 can be slid out of the fixed mold sliding rail 211.

[0083] Embodiment two:
