Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical auxiliary equipment, and particularly relates to an adjustable rib spreader. Background Art
[0002] Rib spreaders are mainly used to expand the thoracic cavity during thoracic surgery, so that doctors can perform surgical operations more conveniently. Especially when surgeries need to be performed on internal thoracic organs such as the heart, rib spreaders can provide the necessary surgical field of view and operating space. However, traditional rib spreaders with fixed sizes often cannot be flexibly adjusted according to specific surgical requirements, which brings certain difficulties to surgical operations. Since the thoracic cavity sizes and shapes of patients vary, fixed-size rib spreaders may not be able to form the best surgical field of view, and may even affect the surgical effect due to inappropriate spreading degrees. In addition, in order to reduce the volume, the existing rib spreaders reduce the contact area between the instrument and the thoracic cavity. However, during the process of expanding the thoracic cavity, the thoracic cavity of the patient deforms, and the relatively small contact area between the instrument and the thoracic cavity may lead to unstable contact, thereby bringing unnecessary complexity to the surgical process. Summary of the Invention
[0003] Aiming at the defects in the prior art, the present invention provides an adjustable rib spreader.
[0004] An adjustable rib spreader includes a mounting bracket. The mounting bracket includes a mounting cross plate. A sliding groove is formed on the bottom surface of the mounting cross plate. A sliding block is clamped in the sliding groove. A threaded hole is formed on the sliding block, and a screw rod arranged on the sliding groove is assembled in the threaded hole. Among them, a fixed spreading part is fixed to the right side of the bottom surface of the mounting cross plate. The fixed spreading part includes a first contact part in a vertical state. A mounting corner platform is fixed to the bottom surface of the sliding block. A rotating pair is arranged on the mounting corner platform, and a movable spreading part capable of rotating around it is connected to the rotating pair. The movable spreading part includes a second contact part in a vertical state and facing the first contact part. An elastic buffer structure is arranged between the movable spreading part and the mounting corner platform. The mounting bracket can be freely mounted on the surgical platform or other positions according to different surgical positions, and may adopt various design elements, such as telescopic rods, adjustable clamps, suction cups, or interfaces compatible with other medical devices.
[0005] Preferably, the fixed spreading part further includes a first holding plate fixed to the right side of the bottom surface of the mounting cross plate. The left edge of the first holding plate is bent and extended to form the first contact part. The first holding plate provides a stable support for the first contact part. The bending and extending structure enables the first holding plate and the first contact part in the vertical state to be integrally formed. The first contact part in the vertical state can better adapt to the shape of the patient's thoracic cavity, provide a larger contact area, and thus enhance the stability.
[0006] Preferably, a rotation area is provided on the right side of the mounting angle platform, and the rotating pair is inserted through the rotation area. The movable expanding part extends into the rotation area and is connected to the rotating pair. The design of the rotation area allows the movable expanding part to have sufficient space to rotate freely while maintaining a firm connection with the mounting angle platform. This flexibility ensures that the movable expanding part can closely fit the patient's chest cavity.
[0007] Preferably, the movable expanding part further includes a second retaining plate. The second retaining plate includes a connecting protrusion located on the left side, and the connecting protrusion extends into the rotation area and is connected to the rotating pair. Wherein, the right edge of the second retaining plate is bent and extended to form the second contact part. The second retaining plate is connected to the rotating pair through the connecting protrusion, realizing the function of stable rotation of the movable expanding part. Similarly, the bending and extending structure enables the second retaining plate and the second contact part in the vertical state to be integrally formed. After the second contact part cooperates with the first contact part, the distance between the two can be flexibly adjusted according to the shape of the chest cavity to ensure stable contact and support.
[0008] Preferably, a first fixing hole is provided on the right side of the mounting angle platform, and the elastic buffer structure is fixed in the first fixing hole. Fixing the elastic buffer structure in the first fixing hole of the mounting angle platform helps to assist the slight rotation of the movable expanding part during the process of expanding the chest cavity, absorb the generated impact force, and protect the patient's chest cavity from excessive compression.
[0009] Preferably, the second retaining plate further includes a second fixing hole located at the bottom left side, and the elastic buffer structure is fixed in the second fixing hole. The second fixing hole is used to fix the other end of the elastic buffer structure, and together with the first fixing hole, it ensures that the elastic buffer structure can effectively play a role during the movement of the movable expanding part and provide a stable buffering effect.
[0010] Preferably, the elastic buffer structure includes a tension spring. One end of the tension spring is fixed in the first fixing hole, and the other end of the tension spring is fixed in the second fixing hole. As the elastic buffer structure, the tension spring has good elasticity and resilience, and can provide a stable buffering force and pulling force when the movable expanding part moves, ensuring that the movable expanding part will not easily change its angle.
[0011] Preferably, threaded holes are provided on both the sliding block and the mounting angle platform, and a bolt structure is inserted through the threaded holes. The sliding block and the mounting angle platform are firmly connected through the bolt structure, ensuring the stability and safety of the chest opener during use. At the same time, this connection method is also convenient for disassembly and maintenance.
[0012] Preferably, a first contact surface is provided on the right side surface of the first contact portion, and a second contact surface is provided on the left side surface of the second contact portion. Both the first contact surface and the second contact surface are anti-slip and have a certain elasticity to improve the comfort of the patient. At the same time, these two contact surfaces are directly and closely attached to the patient's chest cavity.
[0013] Preferably, a first bending portion that bends to the right extends from the front side of the first contact portion, and a second bending portion that bends to the left extends from the front side of the second contact portion. The design of the first bending portion and the second bending portion can, on the one hand, better adapt to the shape of the patient's chest cavity, and on the other hand, provide a larger contact area and more stable support, reducing the sense of compression or discomfort that the rib spreader may cause to the patient during use, and at the same time improving the anti-slip property.
[0014] The beneficial effects of the present invention are reflected in:
[0015] In the entire adjustable rib spreader of the present invention, through the cooperation of the screw and the screw hole, and the limiting effect of the sliding groove on the sliding block, the doctor can precisely control the relative distance between the second contact portion and the first contact portion. This fine adjustment ability is crucial for gradually opening the chest and maintaining stability during the operation. It allows the doctor to gradually and precisely adjust the degree of chest opening according to the progress of the operation and the specific conditions of the patient. Further, due to the provision of the rotating pair, the movable spreading portion (i.e., the second contact portion) can always closely adhere to the patient's chest cavity during the movement. This design effectively avoids the gaps caused by the angle changes due to the position changes generated by the gradual movement during the chest opening process, ensuring the stability of the contact area between the rib spreader and the patient's chest cavity, thereby improving the stability of fixation. Further, by providing an elastic buffer structure to assist the angle change of the movable spreading portion and ensure more stable support, the reliability of the close adhesion is further improved. This rib spreader significantly reduces the accidental risk caused by sliding during the operation, which not only makes the chest opening process safer, but also ensures the stable fixation of the patient's chest during the entire operation process and can better resist external small vibrations or shakes, which is particularly important in the operating room environment because any accidental movement may affect the accuracy and safety of the operation.

[0025] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0026] Such as Figures 1 to 4As shown, an adjustable chest opener includes a mounting bracket, which includes a mounting horizontal plate 1, a sliding groove 2 is provided on the bottom surface of the mounting horizontal plate 1, a sliding block 3 is clamped in the sliding groove 2, a screw hole 31 is provided on the sliding block 3, and a screw 4 arranged on the sliding groove 2 is assembled in the screw hole 31; wherein, a fixed support portion 5 is fixed to the right side of the bottom surface of the mounting horizontal plate 1, and the fixed support portion 5 includes a first contact portion 51 in a vertical state; a mounting angle platform 6 is fixed to the bottom surface of the sliding block 3, and a rotating pair 61 is provided on the mounting angle platform 6, and the rotating pair 61 is connected to a movable support portion 7 that can rotate around it, and the movable support portion 7 includes a second contact portion 71 in a vertical state and opposite to the first contact portion 51; an elastic buffer structure 8 is provided between the movable support portion 7 and the mounting angle platform 6.
[0027] In this embodiment, it should be noted that the mounting bracket can be freely installed on the surgical platform or other locations according to different surgical locations, and may adopt a variety of design elements, such as retractable rods, adjustable clamps, suction cups, or interfaces compatible with other medical devices.
[0028] It should also be noted that, through the cooperation of the screw rod 4 and the screw hole 31, and the limiting effect of the sliding groove 2 on the sliding block 3, the doctor can accurately control the relative distance between the second contact portion 71 and the first contact portion 51. This fine adjustment ability is crucial for gradually opening the chest and maintaining stability during the operation. It allows the doctor to gradually and accurately adjust the degree of chest opening according to the progress of the operation and the specific situation of the patient; further, due to the provision of the rotating pair 61, the movable expansion portion 7 (i.e., the second contact portion 71) can always fit closely with the patient's chest cavity during the movement. This design effectively avoids the position change caused by gradual movement during the chest opening process. The gap caused by the angle change ensures that the contact area between the chest opener and the patient's chest cavity is stable, thereby improving the stability of fixation; further, by providing an elastic buffer structure 8, the angle change of the movable expansion part 7 is assisted to ensure more stable support and further improve the reliability of close fit. This chest opener significantly reduces the risk of accidents caused by sliding during surgery, which not only makes the chest opening process safer, but also ensures the stable fixation of the patient's chest throughout the operation and is more resistant to small external vibrations or shaking. This is especially important in the operating room environment because any unexpected movement may affect the accuracy and safety of the operation.
