Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a device for reducing rib fractures. Background Art

[0002] Traditional rib fracture surgery requires a large incision. To reduce surgical trauma, minimally invasive rib fracture chest fixation surgery has emerged. This involves using a thoracoscopic rib fixator to fix the broken ribs in the chest cavity. However, commonly used fixation devices have poor positioning and are difficult to accurately align dislocated ribs. Summary of the Invention

[0003] In order to solve the above technical problems and facilitate the docking of ribs, the present invention provides a rib fracture reduction device, and the technical solutions adopted are as follows:

[0004] The rib fracture reduction device provided by the present invention includes a fixing frame and a support rod. The fixing frame includes a cross bar and two first vertical rods. The two first vertical rods are respectively located at the two ends of the cross bar. The middle part of the support rod is installed in the middle part of the cross bar. The support rod is perpendicular to the cross bar. Swing arms are respectively arranged at both ends of the support rod. A straight rod is arranged at one end of the swing arm. A bone needle is arranged at the lower end of the straight rod. Sleeves for installing the swing arm are respectively arranged at both ends of the support rod. The outer side of the sleeve is formed with an installation shaft for installing the swing arm.

[0005] Furthermore, a locking assembly for installing a bone needle is arranged at the lower end of the straight rod. The locking assembly includes a fixing part and a locking part. The fixing part is formed with a through hole for the bone needle to pass through. The locking part is screwed into the side wall of the through hole through a thread and presses against the bone needle.

[0006] Furthermore, a limiting hole for inserting a limiting nail is formed at the lower end of the bone needle, and the insertion direction of the limiting nail is perpendicular to the length direction of the bone needle.

[0007] Furthermore, a locking nut for fastening the swing arm is arranged at the top end of the mounting shaft.

[0008] Furthermore, a locking screw is arranged on the side wall of the sleeve.

[0009] Furthermore, second vertical rods are respectively arranged at both ends of the support rod.

[0010] Beneficial Effects: During clinical use, the swing arm can be adjusted in two dimensions, vertically and horizontally. Minimally invasive surgery is used to install the bone pins on the broken ribs, and then the swing arm is adjusted to align the ribs. The invention has a reasonable structure and is easy to operate, and can be widely used in the field of medical device technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a structural diagram of the reset device. DETAILED DESCRIPTION

[0012] The following combination Figure 1 The present invention is further described.

[0013] The present invention relates to a device for reducing rib fractures, which includes a fixing frame and a support rod 13. The fixing frame is placed in front of the chest. The fixing frame includes a cross bar 11 and two first vertical rods 12. The two first vertical rods 12 are respectively located at the two ends of the cross bar 11. The two first vertical rods 12 are against the patient's chest. The middle part of the support rod 13 is installed in the middle part of the cross bar 11. The support rod 13 is perpendicular to the cross bar 11. The two ends of the support rod 13 are respectively provided with swing arms 14. One end of the swing arm 14 is provided with a straight rod 15. The lower end of the straight rod 15 is provided with a bone needle 16. Clinically, minimally invasive surgery is used to drill holes in the two broken ribs, and the two bone needles 16 are inserted into the corresponding holes in the ribs. In some embodiments, in order to stabilize the support rod 13, the two ends of the support rod 13 are respectively provided with second vertical rods, and the second vertical rods are against the patient's chest.

[0014] The two ends of the support rod 13 are respectively provided with sleeves 17 for mounting the swing arm 14. The sleeves 17 are sleeved on the ends of the support rod 13, and the swing arm 14 can rotate around the support rod 13. The outer side of the sleeve 17 is formed with a mounting shaft 18 for mounting the swing arm 14, and the swing arm 14 can rotate around the mounting shaft 18.

[0015] The top end of the mounting shaft 18 is provided with a locking nut for fastening the swing arm 14, and the side wall of the sleeve 17 is provided with a locking screw. After the swing arm 14 is rotated to adjust the position of the rib docking, the position of the swing arm 14 is fixed by the locking nut and the locking screw.

[0016] A locking assembly for mounting the bone needle 16 is arranged at the lower end of the straight rod 15. The locking assembly includes a fixing portion 19 and a locking portion 20. The fixing portion 19 is formed with a through hole for the bone needle 16 to pass through. The locking portion 20 is screwed into the side wall of the through hole through a thread and presses against the bone needle 16, thereby fixing the bone needle 16. A screw can be used as the locking portion 20.

[0017] The lower end of the bone needle 16 is formed with a limiting hole for inserting a limiting nail, and the insertion direction of the limiting nail is perpendicular to the length direction of the bone needle 16. The limiting nail is inserted into the corresponding limiting hole using minimally invasive means to prevent the bone needle 16 from falling out of the rib.

[0018] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
