Description

Technical Field

[0001] This utility model relates to the field of surgical instruments, and in particular to a rib fixation plate. Background Technology

[0002] Rib fixation plates are an important surgical instrument in thoracic surgery. They are used to join and fix two rib segments together.

[0003] Traditional rib fixation plates are typically made from solid plates of uniform thickness, and vary in type, including those with and without claws. For example, CN304515755S discloses a rib fixation plate made from a solid plate of uniform thickness. However, ribs have inherent curves and twists, and traditional, longer rib fixation plates struggle to conform to these curves and twists, while shorter plates offer relatively poor fixation. Furthermore, while fully perforated rib fixation plates can conform to rib curves and twists, their strength is relatively low. Utility Model Content

[0004] The purpose of this invention is to provide a rib fixation plate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rib fixation plate includes: a serrated plate segment and two solid plate segments. The serrated plate segment is located between and connected to the two solid plate segments. The surface of the serrated plate segment has multiple serrated grooves. The multiple serrated grooves are arranged along the length direction of the rib fixation plate. Along the width direction of the rib fixation plate, the serrated grooves connect the two ends of the rib fixation plate. The solid plate segments have a plurality of screw holes for mounting screws. The plurality of screw holes are arranged along the length direction of the rib fixation plate.

[0007] As a further aspect of this invention: a serrated plate segment has multiple serrated grooves formed on one side in the thickness direction. The other side of the serrated plate segment in the thickness direction is configured as a surface without grooves and integrally coplanar with the surface of the solid plate segment.

[0008] As a further embodiment of this invention: the serrated plate segment forms multiple serrated grooves on the side facing the ribs.

[0009] As a further embodiment of this utility model: the serrated plate segment is configured on the side away from the rib as a surface without grooves and integrally coplanar with the surface of the solid plate segment.

[0010] As a further embodiment of this utility model: the serrated plate segment forms multiple serrated grooves on the side opposite to the ribs.

[0011] As a further embodiment of this utility model: the serrated plate segment is configured on the side facing the rib as a surface without grooves and integrally coplanar with the surface of the solid plate segment.

[0012] As a further embodiment of this utility model, the serrated groove is inclined along the length direction of the rib fixation plate.

[0013] As a further embodiment of this utility model: the width of the serrated groove is greater than or equal to 1 mm and less than or equal to 3 mm.

[0014] As a further embodiment of this utility model, the distance between two adjacent sawtooth grooves is greater than or equal to 1 mm and less than or equal to 3 mm.

[0015] As a further aspect of this utility model, the distance between two adjacent sawtooth grooves is approximately equal to the width of the sawtooth groove.

[0016] As a further embodiment of this utility model, the length of the rib fixation plate is greater than 100mm.

[0017] Compared with the prior art, the advantages of this utility model are: the rib fixation plate is easy to bend and twist, can adapt to the shape and twist of the rib, and has a better fixation effect and higher strength.

[0018] The multiple serrated grooves allow the rib fixation plate to adapt to the shape of the ribs, allowing for bending and twisting. Compared to shorter rib fixation plates, it offers better fixation. By placing the force transmission point of the rib fixation plate away from the fracture site, the fixation effect is improved, avoiding the potential for hindering healing if the point is too close to the fracture. Compared to a fully perforated design, it offers increased strength.

[0019] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0026] 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.

[0027] like Figures 1 to 5 As shown, a rib fixation plate 100 includes a serrated plate segment 10 and two solid plate segments 20. The serrated plate segment 10 is located between the two solid plate segments 20 and is connected to the two solid plate segments 20. Various connection methods can be used, such as riveting, welding, or integral molding; this utility model does not limit this. The surface of the serrated plate segment 10 has multiple serrated grooves 11. The multiple serrated grooves 11 are arranged along the length direction of the rib fixation plate 100, and each serrated groove includes a concave portion and a convex portion. In the width direction of the rib fixation plate 100, the serrated grooves 11 connect the two ends of the rib fixation plate 100. The solid plate segments 20 are provided with a plurality of screw holes 21. The screw holes 21 are used to install screws. The plurality of screw holes 21 are arranged along the length direction of the rib fixation plate 100.

[0028] In one specific implementation, the length of the rib fixation plate 100 is greater than 100mm.

[0029] In one specific implementation, the serrated plate segment 10 has multiple serrated grooves 11 formed on one side in the thickness direction. The other side of the serrated plate segment 10 in the thickness direction is set to be a surface without grooves and integrally coplanar with the surface of the solid plate segment 20. This arrangement allows the surface of the fixation plate to fit smoothly against the rib, avoiding damage to body tissues, such as ribs or other adjacent human tissues, due to the uneven structure of the fixation plate surface, which is more conducive to the patient's postoperative recovery.

[0030] In one specific embodiment, the serrated plate segment 10 has multiple serrated grooves 11 formed on the side facing away from the rib. In another specific embodiment, the serrated plate segment 10 has a surface without grooves on the side facing the rib, which is integral and coplanar with the surface of the solid plate segment 20. The arrangement of the serrations away from the rib facilitates installation, and the operator can also determine the location based on the deformation state of the serrated grooves.

[0031] As an alternative implementation, the serrated plate segment has multiple serrated grooves formed on the side facing the rib. Specifically, the side of the serrated plate segment facing away from the rib is configured as a non-grooved surface that is integrally coplanar with the surface of the solid plate segment. In this way, the rib and adjacent tissues will engage with the serrated grooves during growth and healing, thereby making the fixation of the rib plate more secure.

[0032] As one specific implementation, the serrated groove 11 is inclined along the length direction of the rib fixation plate 100. Since the human ribs themselves do not extend horizontally but have a certain angle, the inclined serrated groove can better match the shape and angle of the human ribs themselves.

[0033] In one specific implementation, the width of the serrated groove 11 is greater than or equal to 1 mm and less than or equal to 3 mm. Specifically, the width of the serrated groove 11 is greater than or equal to 1.5 mm and less than or equal to 2.5 mm. The groove width refers to the width of the serration itself. A groove width above the lower limit prevents the protruding parts of the serrated groove from being too sharp and damaging human tissue; a groove width below the upper limit allows for fuller utilization of the space in the serrated segment, thus enabling free adjustment of the serrated segment.

[0034] In one specific implementation, the distance between two adjacent serrated grooves 11 is greater than or equal to 1 mm and less than or equal to 3 mm. Specifically, the distance between two adjacent serrated grooves 11 is greater than or equal to 1.5 mm and less than or equal to 2.5 mm. A groove spacing above the lower limit ensures the rib fixation plate itself has sufficient strength, thus providing adequate support to the rib to meet strength requirements. A groove spacing below the upper limit allows for smoother adjustment of the angle and shape of the rib fixation plate, thereby better conforming to the shape and angle of the rib itself.

[0035] In one specific implementation, the distance between two adjacent sawtooth grooves 11 is substantially equal to the width of the sawtooth groove 11. "Substantially equal" does not mean completely equal, but rather approximately equal, with a possible deviation of up to 20%. With this arrangement, even when the protrusions of the sawtooth grooves extend beyond the solid plate segment, the sawtooth groove portions of the two fixed plates can face each other, thereby reducing space occupancy during transportation.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
