Description

Technical Field

[0001] This invention relates to the field of medical surgical instruments, and in particular to an orthotic device for pectus excavatum and pectus carinatum surgery. Background Technology

[0002] With advancements in medical technology, current treatments for pectus excavatum often employ minimally invasive surgery. This involves inserting a corrective plate into the patient's pleural cavity to support the collapsed sternum. Steel plates or fixation plates are then attached to both ends of the corrective plate, connecting and securing it to the patient's ribs or periosteum. However, a challenge arises because the shape and size of each patient's pleural cavity vary. The shape of the corrective plate supporting the sternum, the location of its connection to the ribs, and the method of fixation all influence the treatment of pectus excavatum. The success or failure of the treatment is determined by the steel plate circumferential arm or fixation plate used in the current technology. In the process of connecting the orthopedic plate and the rib, there are many problems that the relative position between the orthopedic plate and the rib cannot be adjusted or is not easy to adjust. As a result, it is not easy to set the sternum in the optimal position. In addition, the fixation of the steel plate circumferential arm or fixation plate to the rib is mostly done by binding, which results in poor stability of the fixation between the orthopedic plate and the rib. It has the disadvantages of high surgical difficulty, difficulty in obtaining the optimal position of the sternum support, and poor connection stability between the orthopedic plate and the rib. Summary of the Invention

[0003] The purpose of this invention is to provide an orthotic device for pectus excavatum and pectus carinatum surgery to address the shortcomings of existing technologies. This invention adopts the structure of an orthotic long plate, a fixing plate, and self-tapping screws. The fixing plate of this invention is an I-shaped fixing plate or a Y-shaped fixing plate. The I-shaped fixing plate is made of an I-shaped connecting rib and two base plates, and the base plates of the I-shaped fixing plate are respectively located at both ends of the I-shaped connecting rib. The Y-shaped fixing plate is made of a Y-shaped connecting rib and three base plates, and the base plates of the Y-shaped fixing plate are respectively located at the three ends of the Y-shaped connecting rib.

[0004] This invention solves the problem of adjusting the relative position between the orthopedic long plate and the ribs by twisting and bending I-shaped or Y-shaped connecting ribs, which allows for arbitrary setting of the relative spatial position between two base plates on an I-shaped fixing plate or between three base plates on a Y-shaped fixing plate.

[0005] This invention addresses the connection stability issue between the orthopedic plate and the ribs by having one base plate on the I-shaped fixation plate overlap with the wedge-shaped segment of the orthopedic plate, and another base plate on the I-shaped fixation plate overlap with the patient's ribs, both secured with self-tapping screws; or by having one base plate on the Y-shaped fixation plate overlap with the wedge-shaped segment of the orthopedic plate, and the other two base plates on the Y-shaped fixation plate overlap with the patient's two ribs respectively, both secured with self-tapping screws.

[0006] The specific technical solution for achieving the objective of this invention is as follows:

[0007] An orthotic device for pectus excavatum surgery, characterized by an orthotic long plate, a fixation plate and self-tapping screws;

[0008] The orthopedic plate is a strip-shaped piece, with gradually tapering wedge-shaped sections at both ends along the width direction of the orthopedic plate. Several first screw holes are sequentially provided on the wedge-shaped sections along the axis of the orthopedic plate.

[0009] The fixing piece is an I-shaped fixing piece or a Y-shaped fixing piece;

[0010] The I-shaped fixing piece is made of an I-shaped connecting rib and two base pieces, and the base pieces of the I-shaped fixing piece are respectively located at both ends of the I-shaped connecting rib;

[0011] The Y-shaped fixing piece is made of a Y-shaped connecting rib and three base pieces, and the base pieces of the Y-shaped fixing piece are respectively located at the three ends of the Y-shaped connecting rib;

[0012] The substrate is rectangular, and several second screw holes are sequentially provided on the substrate along the axis of the rectangular shape;

[0013] The I-shaped fixing piece consists of two pieces, which are respectively located at both ends of the orthopedic long plate. A base plate on the I-shaped fixing piece overlaps with the wedge-shaped section of the orthopedic long plate, and several self-tapping screws are fixed together through the second screw hole of the base plate and the first screw hole of the orthopedic long plate.

[0014] The Y-shaped fixing piece consists of two pieces, which are respectively located at both ends of the orthopedic long plate. One base plate on the Y-shaped fixing piece overlaps with the wedge-shaped section of the orthopedic long plate, and several self-tapping screws are fixed together through the second screw hole of the base plate and the first screw hole of the orthopedic long plate.

[0015] The orthopedic long plate is arched along its length, with an arc-shaped middle section and bent wedge-shaped sections at both ends.

[0016] One substrate of the I-shaped fixing plate is connected to another substrate by an I-shaped connecting rib. Bending or folding the I-shaped connecting rib makes the spatial relative position between the substrates adjustable.

[0017] The two substrates of the Y-shaped fixing piece are connected to another substrate by a Y-shaped connecting rib. Bending or folding the Y-shaped connecting rib makes the spatial relative position between the substrates adjustable.

[0018] The orthopedic long plate is made of a flexible and shape-memoryable metal or polymer material.

[0019] The fixing plate is made of a flexible and shape-memoryable metal or polymer material.

[0020] This invention solves the problem of adjusting the relative position between the orthopedic long plate and the ribs by twisting and bending I-shaped or Y-shaped connecting ribs, which allows for arbitrary setting of the relative position between two base plates on an I-shaped fixing plate or between three base plates on a Y-shaped fixing plate.

[0021] This invention addresses the connection stability issue between the orthopedic plate and the ribs by having one base plate on the I-shaped fixation plate overlap with the wedge-shaped segment of the orthopedic plate, and another base plate on the I-shaped fixation plate overlap with the patient's ribs, both secured with self-tapping screws; or by having one base plate on the Y-shaped fixation plate overlap with the wedge-shaped segment of the orthopedic plate, and the other two base plates on the Y-shaped fixation plate overlap with the patient's two ribs respectively, both secured with self-tapping screws.

[0022] This invention has the advantages of convenient surgical operation, easy to obtain the optimal position of the sternal support, and good connection stability between the orthopedic plate and the ribs. Attached Figure Description

[0030] Example

[0031] See Figure 6 The proposed solution involves using two I-shaped fixation plates 21 to support the orthopedic long plate 1 and fix it to the position of one rib in the chest.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6During the minimally invasive treatment of pectus excavatum, an orthotic long plate 1 needs to be inserted into the patient's chest cavity to support the collapsed sternum. Fixation plates 2 are set at both ends of the orthotic long plate 1 to support and fix the orthotic long plate 1 to the patient's ribs. Before the operation, the orthotic long plate 1 needs to be shaped according to the shape and size of the patient's chest cavity. The orthotic long plate 1 is arched along its length, with an arc in the middle and a bent wedge-shaped section 11 at both ends. The wedge-shaped section 11 is designed to facilitate bending.

[0033] Two I-shaped fixation plates 21 are selected and respectively set at both ends of the orthopedic long plate 1. The relative position of one base plate of the I-shaped fixation plate 21 and the other base plate in space is set by twisting and bending the I-shaped connecting ribs 211. The I-shaped fixation plates 21 support the orthopedic long plate 1 and fix it to the position of one rib of the chest, so that the sternum supported by the orthopedic long plate 1 is in the optimal position.

[0034] See Figure 2 , Figure 3 , Figure 4 , Figure 6 After the orthopedic plate 1 and I-shaped fixation plate 21 are set up, under the guidance of thoracoscopy, the orthopedic plate 1 is inserted from one side of the chest cavity to a suitable position on the other side. The second screw hole 23 of one base plate on the I-shaped fixation plate 21 overlaps with the first screw hole 12 of the wedge segment 11 of the orthopedic plate 1 and is fixed with a self-tapping screw 3. The other base plate on the I-shaped fixation plate 21 overlaps with the patient's ribs and is fixed with a self-tapping screw 3 through the second screw hole 23. Thus, the purpose of orthopedic treatment of collapsed chest wall in patients with pectus excavatum is achieved.

[0035] Example

[0036] See Figure 7 The proposed solution involves using two Y-shaped fixation plates 22 to support the orthopedic long plate 1 and fix it to the position of the two ribs in the chest.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 During the minimally invasive treatment of pectus excavatum, an orthotic long plate 1 needs to be inserted into the patient's chest cavity to support the collapsed sternum. Fixation plates 2 are set at both ends of the orthotic long plate 1 to support and fix the orthotic long plate 1 to the patient's ribs. Before the operation, the orthotic long plate 1 needs to be shaped according to the shape and size of the patient's chest cavity. The orthotic long plate 1 is arched along its length, with an arc in the middle and a bent wedge-shaped section 11 at both ends. The wedge-shaped section 11 is designed to facilitate bending.

[0038] Two Y-shaped fixing plates 22 are selected and respectively set at both ends of the orthopedic long plate 1. The relative positions of the two base plates of the Y-shaped fixing plates 22 and the other base plate in space are set by twisting and bending the Y-shaped connecting ribs 221. The Y-shaped fixing plates 22 support the orthopedic long plate 1 and fix it to the position of the two ribs in the chest, so that the sternum supported by the orthopedic long plate 1 is in the optimal position.

[0039] See Figure 2 , Figure 3 , Figure 5 , Figure 7 After the orthopedic plate 1 and Y-shaped fixation plate 22 are set up, under the guidance of thoracoscopy, the orthopedic plate 1 is inserted from one side of the chest cavity to a suitable position on the other side. The second screw hole 23 of one base plate on the Y-shaped fixation plate 22 overlaps with the first screw hole 12 of the wedge segment 11 of the orthopedic plate 1 and is fixed with a self-tapping screw 3. The other two base plates on the Y-shaped fixation plate 22 overlap with the patient's two ribs respectively and are fixed with the patient's ribs through the second screw hole 23 with a self-tapping screw 3. Thus, the purpose of orthopedic treatment of collapsed chest wall in patients with pectus excavatum is achieved.

[0040] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 This invention employs a combination of an orthotic long plate 1 and an I-shaped fixing plate 21 or a Y-shaped fixing plate 22. By twisting and bending the I-shaped connecting ribs 211 or the Y-shaped connecting ribs 221, the relative spatial positions of the two base plates on the I-shaped fixing plate 21 or the three base plates on the Y-shaped fixing plate 22 can be arbitrarily set to solve the problem of precise adjustment of the relative position between the orthotic long plate and the ribs, thereby ensuring that the sternum supported by the orthotic long plate 1 is in the optimal position. This solves the difficulty of adjusting the relative position between the orthotic long plate and the ribs when connected by a steel plate circumferential arm.

[0041] See Figure 6 , Figure 7 The second screw hole 23 of a substrate on the I-shaped fixing plate 21 or the second screw hole 23 of a substrate on the Y-shaped fixing plate 22 overlaps with the first screw hole 12 of the wedge-shaped section 11 of the straightening long plate 1 and is fixed with self-tapping screws 3.

[0042] See Figure 6 , Figure 7 In this invention, another base plate on the I-shaped fixation plate 21 overlaps with one of the patient's ribs, or two other base plates on the Y-shaped fixation plate 22 overlap with two of the patient's ribs respectively, and self-tapping screws 3 are fixed to the patient's ribs through the second screw hole 23 on the base plate.

[0043] See Figure 6 , Figure 7 In this invention, the I-shaped fixation piece 21 or the Y-shaped fixation piece 22 is fixed to the orthopedic long plate 1 with self-tapping screws 3, and the I-shaped fixation piece 21 or the Y-shaped fixation piece 22 is fixed to the patient's ribs with self-tapping screws 3, which overcomes the loosening or slippage of the binding connection and solves the problem of connection stability between the orthopedic long plate 1 and the ribs.

[0044] See Figure 1 , Figure 3 , Figure 4 To ensure the corrective effect of pectus excavatum and pectus carinatum, the corrective plate 1 and the fixing plate 2 of this invention are made of metal or polymer materials that are flexible and shape-memoryable.
