Description

Technical Field

[0001] This utility model relates to the field of implant processing technology, specifically to an electric Nuss orthopedic plate forming machine. Background Technology

[0002] The Nuss procedure involves inserting a Nuss plate under thoracoscopic guidance to support the collapsed sternum, while the deformed costal cartilages on either side are pushed outwards. The Nuss plate is secured at both ends with a fixator with two holes, which is then wrapped and secured to the ribs with wire to support the collapsed sternum, thus achieving chest wall correction. After the plate is implanted and the desired correction is achieved, the plate needs to be removed approximately two to three years later when the chest wall has fully reshaped. The Nuss procedure has become a widely used surgical method for correcting pectus excavatum using a plate-supported approach in recent years.

[0003] In existing techniques, the Nuss orthotic plate is typically pre-bent based on the patient's chest X-ray and the surgeon's experience before surgery to ensure it meets the patient's orthodontic needs. To achieve this bending, bending forceps are usually used in existing techniques.

[0004] For example, Chinese patent CN201721284013.1 discloses a novel specialized tool for minimally invasive treatment of chest wall deformities. It includes a base and a vertical rod mounted on the base. From top to bottom, the vertical rod is fitted with a fixing component, a bending component, and a bending ring. The fixing component and bending component are positioned near the top of the vertical rod, while the bending ring is positioned near the base. This design effectively achieves a large bending angle, multiple bending patterns, and a large number of bends by utilizing the cooperation of the fixing component, bending component, and bending ring positioned on the vertical rod, thereby solving the technical problems existing in current bending pliers.

[0005] For example, Chinese patent CN201821588246.5 discloses a steel plate shaping device for pectus excavatum correction surgery, including an arched body, a steel plate clamping device, and a shaping rod. The arched body has steel plate clamping devices at both ends. Each steel plate clamping device includes a connecting shaft on the arched body, a slider in contact with the connecting shaft surface, and a track groove along the length of the slider that mates with the connecting shaft. The slider moves in a straight line by contacting the connecting shaft surface through the track groove. A limiting nut is provided at the end of the connecting shaft away from the slider. A U-shaped clamping opening is provided at one end of the slider. A threaded fastener for pressing the steel plate is provided at the opening end of the U-shaped clamping opening. A shaping rod is provided at the center of the arched body. The threaded connecting rod and the clamping rod are connected by a bearing, and both the threaded connecting rod and the clamping rod can rotate freely. A U-shaped clamping frame is provided at the front end of the clamping rod, and a limiting boss is provided at the opening end of the U-shaped clamping frame. During use, the shaping device is used as a template to place the orthopedic plate into the arched body and bend it to the corresponding shape to achieve the bending process of the orthopedic plate.

[0006] However, in actual implementation, the inventors found that although this type of technical solution uses principles such as levers to reduce bending force, the shaping process still requires doctors to manually bend and shape it with considerable strength, which is time-consuming and laborious.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0051] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0052] This utility model includes:

[0053] An electric Nuss orthopedic plate shaping machine, such as Figure 1 As shown, it includes a shaping machine body 1, and a clamping device 2 is provided at the front end of the shaping machine body 1;

[0054] The clamping device includes a fixed end 21 and a movable end 22, and the orthopedic plate mold 3 is clamped between the fixed end 21 and the movable end 22;

[0055] The movable end 22 pushes the orthotic mold 3 toward the fixed end 21 to close, so that the Nuss orthotic plate held in the orthotic mold 3 is processed into a preset shape.

[0056] Specifically, in view of the problem that the bending process of Nuss orthopedic plates in the existing technology mainly relies on manual labor, which is time-consuming and labor-intensive, this solution introduces the aforementioned electric Nuss orthopedic plate forming machine to replace the manual processing process. This allows the Nuss orthopedic plate to be processed into a predetermined shape without the need for manual pressing, thus saving manpower.

[0057] Specifically, the electric Nuss orthopedic plate shaping machine includes a shaping machine body 1, which is equipped with a corresponding power device, such as a motor, electric cylinder, or other equivalent device, capable of controlled movement to provide corresponding power. A clamping device 2 is located at the front end of the shaping machine body 1, and the clamping device 2 is connected to the power device via a transmission connection, enabling the fixed end 21 and the movable end 22 to move relative to each other and establish a certain pressure.

[0058] The orthopedic plate mold 3 is held between the fixed end 21 and the movable end 22. The orthopedic plate mold 3 can be a split type, such as including two parts respectively set on the side wall between the fixed end 21 and the movable end 22, or it can be an integral type, such as the mold itself having an independent opening and closing structure, which can be used to put in the orthopedic plate and then be pushed closed and pressed by the movable end 22.

[0059] The Nuss orthopedic plate is the orthopedic device mentioned in the prior art. In its initial state, it is a long iron sheet. It can be bent into a shape with a specific curvature according to the needs of the surgery to meet the requirements of implantation and orthopedic correction. When bending is required, the Nuss orthopedic plate is fully or partially inserted into the gap of the orthopedic plate mold 3. After the orthopedic plate mold 3 is closed, it is deformed by pressure and bent into the predetermined shape.

[0060] The main body 1 of the shaping machine is also equipped with a locking and unlocking switch, which is used to maintain the shape of the Nuss orthopedic plate and to unlock it.

[0061] In one embodiment, the front end of the forming machine body 1 is provided with a clamping device bracket 11 and a push rod 12;

[0062] A fixed end 21 is fixed to the front end of the clamping device bracket 11;

[0063] The push rod 12 passes through the clamping device bracket 11 and the fixed end 21 and reaches the inside of the fixed end 21, where it abuts against the movable end 22.

[0064] Specifically, to achieve the power transmission process, in this embodiment, a clamping device bracket 11 and a push rod 12 are provided at the front end of the forming machine body 1. The clamping device bracket 11 is a hollow structure, and its exterior is fixedly connected to the shell of the forming machine body 1. The push rod 12 passes through the middle of the clamping device bracket 11. The first end of the push rod 12 is connected to the power device inside the forming machine body 1, and the second section of the push rod 12 abuts against the movable end 22, so as to push the movable end 22 to move and establish mold closing pressure when the power device is operating.

[0065] In one embodiment, the power unit is a motor, the push rod 12 is a screw structure, and the push rod 12 meshes with the reducer gear arranged on the motor shaft. As the reducer gear rotates, the torque is converted into kinetic energy in the axial direction.

[0066] In another embodiment, the power unit is an electric cylinder, and the push rod 12 is connected to the output piston of the electric cylinder and moves under the push of the cylinder.

[0067] In one embodiment, the fixed end 21 has a U-shaped cross-section, and the movable end 22 is disposed on the first side wall of the fixed end 21 and connected to the push rod 12.

[0068] The bottom of the fixed end 21 is provided with a movable end slide rail 221, and the bottom surface of the movable end 22 is embedded in the movable end slide rail 221 and moves back and forth in the movable end slide rail 221.

[0069] Specifically, to achieve the above-mentioned closing process of the orthopedic mold 3, in this embodiment, the cross-section of the fixed end 21 is set as a U-shaped or C-shaped structure, and the movable end 22 is set on one of the side walls, namely the first side wall. The first side wall has an opening so that the push rod 12 can pass through and connect to the movable end 22. The bottom of the fixed end 21, which is perpendicular to the first side wall, is provided with a movable end slide rail 221. The side of the movable end slide rail 221 is formed by a groove, a protruding structure, or a zigzag shape, etc. The bottom of the movable end 22 is provided with a corresponding matching structure that extends into the movable end slide rail 221 and provides vertical and lateral limits, so that the movable end 22 can only slide along the long axis of the movable end slide rail 221 under the drive of the push rod 12 to achieve the pressing process.

[0070] To enable the pressing process of orthopedic plates of different sizes, this solution provides the following two embodiments of orthopedic plate molds:

[0071] Example 1:

[0072] In one embodiment, such as Figure 2 As shown, the orthopedic mold 3 includes a fixed mold 31 and a movable mold 32;

[0073] The fixed mold 31 is installed in the fixed end 21 on the side opposite to the movable end 22;

[0074] The movable mold 32 is installed on the side of the movable end 22 facing the fixed mold 31;

[0075] A fixed mold slide rail 211 is provided on the side wall of the fixed end 21, and the fixed mold 31 is connected to the fixed end via the fixed mold slide rail 211;

[0076] The movable end 22 is provided with a movable mold slide rail 221 on its side wall, and the movable mold 32 is connected to the movable end 22 via the movable mold slide rail 212.

[0077] Specifically, in order to realize the pressing process of the Nuss orthopedic plate, in this embodiment, the orthopedic plate mold 3 is divided into a fixed mold 31 and a movable mold 32. The fixed mold 31 is used as a male mold with a convex surface, and the movable mold 32 is used as a female mold with a concave surface.

[0078] The fixed end 21 has a fixed mold slide rail 211 on its side wall, and the movable end 22 has a movable mold slide rail 221 on its side wall. The slide rails are opened along the side wall and have a trapezoidal guide groove structure. Corresponding trapezoidal sliders are machined at corresponding positions on the fixed mold 31 and the movable mold 32. The trapezoidal sliders slide into the trapezoidal guide groove structure from one end, thereby realizing the replacement of the orthopedic plate mold 3.

[0079] Depending on the curvature of the Nuss orthotic plate that needs to be bent, multiple sets of orthotic plate molds 3 with different radii of curvature are pre-designed for replacement to match processing requirements.

[0080] In addition, to achieve a better fixing effect, ball pin fixing devices are also provided between the fixed mold 31 and the fixed mold slide rail 211, and between the movable mold 32 and the movable mold slide rail 212, so as to lock the mold after it slides into the guide rail and prevent it from slipping during transportation.

[0081] like Figure 3As shown, taking the ball pin fixing device 5 between the fixed mold 31 and the fixed mold slide rail 211 as an example, a through hole is opened on the fixed end 3 corresponding to the position of the fixed mold slide rail 211. A ball pin fixing screw 51 is provided on the outward side of the through hole. The ball pin fixing screw extends into the through hole and the hollow part of the ball pin spring 52 inside the through hole. The bottom surface of the screw head abuts against the ball pin spring 52. The other end of the ball pin spring 52 abuts against the ball head 53 and applies outward pressure to the ball head 53. A recess is opened on the fixed mold 31 at the position corresponding to the ball head 53. When the fixed mold 31 slides into the fixed mold slide rail 211 and reaches the predetermined position, the ball head 53 will be pushed into the recess by 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 fixing of the fixed mold 31. When it is necessary to disassemble the fixed mold 31, the pressure of the ball pin spring 52 can be reduced by loosening the ball pin fixing screw 51 or the ball head 53 can be pulled out in the opposite direction, so that the limit of the fixed mold 31 disappears and it can slide out of the fixed mold slide rail 211.

[0082] Example 2:

[0083] In one embodiment, such as Figure 4 As shown, the orthopedic mold 3 includes:

[0084] Multiple auxiliary shaping cylinders 33 are distributed on the inner side of the fixed end 21 according to a first preset arc.

[0085] The main shaping cylinder 34 is fixed to the front end of the movable end 22 and moves towards the auxiliary shaping cylinder 33 under the drive of the push rod 12.

[0086] The axes of the auxiliary shaping cylinder 33 and the main shaping cylinder 34 are set perpendicular to the axis of the push rod 12.

[0087] Specifically, this embodiment provides another type of mold head structure implemented using shaping cylinders. This mold head structure consists of multiple shaping cylinders, including an auxiliary shaping cylinder 33 located on one side of the fixed end 21 and a main shaping cylinder 34 located on one side of the movable end 22. When the movable end 22 and the fixed end 21 are closed, the auxiliary shaping cylinder 33 and the main shaping cylinder 34 are located on both sides of the first preset arc and apply pressure to the Nuss straightening plate to bend it.

[0088] Based on this type of mold, when it is necessary to bend the Nuss straightening plate, the positions of the auxiliary shaping cylinder 33 and the main shaping cylinder 34 are adjusted so that the first preset arc conforms to the curvature required by the straightening plate. Then the straightening plate is placed in, and the push rod 12 pushes the main shaping cylinder 34 to move towards the auxiliary shaping cylinder 33, so that the straightening plate is bent into the required curvature.

[0089] In one embodiment, the auxiliary shaping cylinder 33 includes a movable auxiliary shaping cylinder 331 and a fixed auxiliary shaping cylinder 332;

[0090] A cylindrical guide groove 333 is provided on the cylindrical mounting surface of the fixed end 31 in the area corresponding to the movable auxiliary shaping cylinder. The bottom end of the movable auxiliary shaping cylinder is inserted into the cylindrical guide groove 333 and slides in the cylindrical guide groove 333.

[0091] A positioning nut 334 is provided on the outer side of the movable auxiliary shaping cylinder relative to the fixed end. The positioning nut 334 passes through the side wall of the fixed end 31 to reach the outside of the fixed end 31.

[0092] Specifically, in this embodiment, to facilitate the adjustment of the mold curvature and thus obtain shaping plates with different curvatures, the auxiliary shaping cylinder 33 is configured into two types: a movable auxiliary shaping cylinder and a fixed auxiliary shaping cylinder 332. The fixed auxiliary shaping cylinder 332 is a cylinder vertically fixed to the cylindrical mounting surface of the fixed end 31, while the auxiliary shaping cylinder 33 is a movable cylinder installed in the cylindrical guide groove 333.

[0093] The cylindrical guide groove 333 is formed on the cylindrical mounting surface of the fixed end 31. Its radius direction coincides with that of the first preset arc. This allows the bottom end of the movable auxiliary shaping cylinder to be inserted into the cylindrical guide groove 333 and slide in the cylindrical guide groove 333, thereby changing the curvature and radius of the first preset arc to meet the bending requirements of different types of Nuss orthopedic plates.

[0094] During the processing, the first preset arc type and curvature of each point are determined according to the requirements of the Nuss straightening plate that needs to be bent. Then, the position of the movable auxiliary shaping cylinder in the cylinder guide groove 333 is adjusted according to the curvature. After reaching the predetermined position, it is locked by the positioning nut 334, so as to conform to the first preset arc.

[0095] Subsequently, as Figure 5 As shown, the Nuss orthopedic plate is clamped, and the main shaping cylinder 34 is pushed to bend.

[0096] Depending on the embodiment, there can be different combinations between the movable auxiliary shaping cylinder and the fixed auxiliary shaping cylinder 332, for example, as Figure 4 A movable auxiliary shaping cylinder is set between the two fixed auxiliary shaping cylinders 332 shown, such as... Figure 6 As shown, a fixed auxiliary shaping cylinder 332 has a movable auxiliary shaping cylinder on each side, such as... Figure 7 All of the shown items are composed of movable auxiliary shaping cylinders, etc.

[0097] To facilitate user operation, the main body 1 of the forming machine includes two configurations: a handheld main unit 1A or a vertical main unit 1B, or other shapes that are easy to place or hold.

[0098] Among them, such as Figure 1 As shown, the handheld main unit 1A includes a first body and a handle, the first body and the handle are set at an angle, the clamping device is set at the front end of the first body, and the handle is provided with a trigger structure for controlling the bending process;

[0099] During use, the doctor holds the main body 1 of the orthopedic machine by hand handle, and installs the orthopedic plate mold 3 with the corresponding curvature and shape on the clamping device 2 or adjusts the cylindrical layout. Then, the orthopedic plate is clamped in the orthopedic plate mold 3, and the power device is triggered by the trigger to close the orthopedic plate mold 3, and the orthopedic plate is bent.

[0100] like Figure 8 As shown, the vertical main unit 1B includes a second body, which is rectangular in shape, and the clamping device 2 is located at the front end of the second body.

[0101] During use, the vertical main unit 1B is fixed on the table, and the clamping device 2 is set above or diagonally above the main unit. The doctor installs the orthopedic plate mold 3 with the corresponding curvature and shape on the clamping device 2 or adjusts the cylindrical layout. Then, the orthopedic plate is clamped in the orthopedic plate mold 3. The power device is triggered by the trigger to close the orthopedic plate mold 3 and the orthopedic plate is bent.

[0102] In one embodiment, such as Figure 1 As shown, a battery 6 is installed at the bottom of the main body 1 of the shaping machine.

[0103] Specifically, to facilitate the movement and use of the main body 1 of the shaping machine in various situations, a battery 6 is also installed at the bottom of the main body 1 to supply power to the power unit inside the main body 1. The battery 6 is either detachable or fixed and can be charged through the power supply interface of the main body 1 or an external charging base. A power indicator light is also designed on the main body 1.

[0104] In addition, the main body 1 of the configuration machine is also equipped with an AC power interface for connecting to external AC power for driving or charging.

[0105] In one embodiment, such as Figure 1 and Figure 9 As shown, the main body 1 of the forming machine is provided with a foot switch interface 71, which is connected to an external foot switch 72.

[0106] Specifically, to facilitate control of the bending process in certain scenarios, such as tabletop installation, this embodiment also includes a foot switch interface 71 on the main body 1 of the forming machine. The foot switch interface 71 is connected to an external foot switch 72 via a connecting cable, enabling the forming machine to be triggered by the foot switch 72. In this scenario, the foot switch 72 can be moved, for example, placed under the tabletop and stepped on to trigger the process.
