[0001] The present invention relates to the technical field of rib fixation, and specifically relates to a rib fracture fixation device. Background Art

[0002] Rib fractures are common chest injuries, and their incidence rate is relatively high among various traumas, accounting for about 90% of thoracic fractures. With the aging of the population and the frequent occurrence of traffic accidents, the incidence rate of rib fractures shows an upward trend. Rib fractures may cause symptoms such as pain and dyspnea, seriously affecting the quality of life of patients and even endangering life. In particular, flail chest caused by multiple rib fractures has a relatively high fatality rate.

[0003] At present, the fixing plates used in some rib fracture fixation devices are arc-shaped rigid fixing plates with fixed radian values, resulting in difficulty in ensuring tight fit with the rib fracture site, thus affecting the fixation effect; moreover, the fixing device lacks an adaptive structure for self-adjusting according to the user's ribs and cannot perform adaptive self-adjustment according to the user's breathing, reducing the comfort of the user during actual use and may also affect the efficiency of rib recovery.

Specific embodiments

[0019] The following further describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0020] As Figures 1-3 shown, a rib fracture fixation device includes a fixing part that can be fixed to the front of a patient to fix the fractured rib. The fixing part includes a fixing plate 11. A plurality of connecting columns 12 are provided at the left and right ends of the fixing plate 11, and the surfaces between two adjacent connecting columns 12 are in contact with each other. Deformable metal strips 13 are fixedly connected to both the left and right ends of the fixing plate 11, and the deformable metal strips 13 sequentially pass through all the connecting columns 12 to connect and fix all the connecting columns 12. The deformable metal strip 13 is an aluminum strip. Through the cooperation between a plurality of connecting columns 12, it can fully contact the patient's body and closely fit the rib fracture site, improving the effect of rib fixation. Clamping parts are provided on both sides of the fixing plate 11. The clamping parts can be clamped on both sides of the patient's body, so that the fixing part can be conveniently fixed to the front of the patient. A winding part is provided on the clamping part. The connecting column 12 farthest from the fixing plate 11 in the winding part is connected to the winding part for winding the connecting column 12, so that the connecting column 12 can closely fit the rib fracture site to fix the patient's rib. A respiratory frequency sensor is installed on the fixing plate 11, and the respiratory frequency sensor is used to detect the patient's respiratory frequency. An adjusting part is provided on the clamping part. The adjusting part is electrically connected to the respiratory frequency sensor. The adjusting part can drive the fixing plate 11 and the connecting column 12 to move according to the patient's respiratory frequency. When the patient inhales, the adjusting part can drive the fixing plate 11 and the connecting column 12 to move away from the patient's body. When the patient exhales, the adjusting part can drive the fixing plate 11 and the connecting column 12 to move towards the patient's body, so that the fixing plate 11 and the connecting column 12 are adaptively adjusted according to the patient's respiratory frequency to adapt to the expansion and contraction of the chest cavity during the patient's breathing, improving the patient's comfort.

[0021] As Figure 1 shown, the clamping part includes two nuts 21, and the nuts 21 are located behind the patient. A bidirectional threaded rod 23 is connected to the internal threads of the two nuts 21. Mounting plates 22 are fixedly connected to both of the two nuts 21, and the mounting plates 22 are located on the left and right sides of the patient's body. Clamping plates 24 are fixedly connected to the mutually approaching side surfaces of the two mounting plates 22. An arc-shaped notch is formed at one end of the clamping plate 24 close to the body, which can fit the patient's body more closely. By rotating the bidirectional threaded rod 23, the two nuts 21 can be driven to move towards each other. When the two move towards each other, the clamping plates 24 can be driven to move, so that the mounting plates 22 can be fixed to the patient's body, and then the fixing plate 11 and the connecting column 12 can be conveniently fixed to the front of the patient's chest cavity.

[0022] As Figure 2 shown, the winding part includes two fixing blocks 31 arranged on the mounting plate 22. A winding roller 32 is rotatably connected between the two fixing blocks 31. The connecting column 12 farthest from the fixing plate 11 is connected to the winding roller 32. A first rotary driving part 33 is fixedly connected to one of the fixing blocks 31, and the output end of the first rotary driving part 33 is fixedly connected to the winding roller 32. The first rotary driving part 33 is a servo motor. First, the first rotary driving part 33 is started. The rotation of the output end of the first rotary driving part 33 can drive the winding roller 32 to rotate. When the winding roller 32 rotates, the connecting column 12 can be wound around the winding roller 32, so that the connecting column 12 can be tightened, and then the fractured rib can be fixed.

[0023] As Figure 1 shown, the adjusting part includes two sliding grooves 41 formed in the mounting plate 22. Sliders 42 are slidably connected in the two sliding grooves 41, and the two fixing blocks 31 are respectively fixedly connected to the two sliders 42. A lead screw 43 is connected to the internal threads of the sliders 42. A second rotary driving part 44 is fixedly connected to one end of the mounting plate 22 away from the nut 21, and the output end of the second rotary driving part 44 extends into the sliding groove 41 and is fixedly connected to the lead screw 43. The second rotary driving part 44 is electrically connected to the respiratory frequency sensor. The second rotary driving part 44 is a servo motor. The respiratory frequency sensor converts the detected respiratory frequency into an available output signal and transmits it to the second rotary driving part 44. The second rotary driving part 44 can drive the lead screw 43 to rotate forward and backward during exhalation and inhalation. When the lead screw 43 rotates forward and backward, the slider 42 can be driven to move reciprocally. When the slider 42 moves reciprocally, the fixing plate 11 and the connecting column 12 can be driven to move reciprocally. The reciprocating movement frequency of the fixing plate 11 and the connecting column 12 is the same as the patient's breathing frequency, so that it can be adaptively adjusted according to the patient's breathing frequency, adapt to the expansion and contraction of the chest cavity during the patient's breathing, and improve the patient's comfort.

[0024] As Figure 3 shown, a spacer cloth 14 is fixedly connected to the side surface of the fixing plate 11 close to the body, and the spacer cloth 14 is fixedly connected to the connecting column 12. Moreover, the connecting column 12 contacts the patient's body through the spacer cloth 14, which can effectively improve the comfort of the patient.

[0025] Working principle: First, the clamping part clamps the patient's body, thereby fixing the clamping part to the patient's body. At this time, the fixing plate 11 and the connecting column 12 are located in front of the patient's chest cavity. Then, the winding part is started. The winding part can wind the connecting column 12, so as to tighten the connecting column 12, and then the fractured rib can be fixed. Finally, the adjusting part is electrically connected to the respiration frequency sensor. The adjusting part can drive the fixing plate 11 and the connecting column 12 to move reciprocally according to the respiration frequency of the patient. The reciprocating movement frequency of the fixing plate 11 and the connecting column 12 is the same as the respiration frequency of the patient, so that it can be adaptively adjusted according to the patient's respiration frequency, adapt to the expansion and contraction of the chest cavity during the patient's respiration, and improve the comfort of the patient.
