Problems solved by technology

[0003] At present, in the process of fracture surgery, in order to ensure the stability of the human body and bone structure, the fracture site is often fixed to meet the needs of surgical stability, but the current general fixation device is in use. There are too many steps to connect and fix with the patient, and the follow-up adjustment is also very inconvenient. It needs to be released or forced to pull to meet the fine adjustment of the position. Secondary damage to muscle tissue due to excessive traction

Embodiment 1

[0034] like Figure 1-8 As shown, an auxiliary fixation device for fracture operation includes a long plate 1, an installation chamber 11 is opened in the middle of the long plate 1, an adjustment mechanism is arranged in the installation chamber 11, and two outer centers of the long plate 1 are symmetrically arranged with the adjustment mechanism. fixed mechanism;

[0035] The adjustment mechanism includes a central gear 2, a transmission handle 21 and two transmission racks 3. The central gear 2 is rotatably arranged in the middle of the installation chamber 11. The transmission handle 21 is arranged on the side of the long board 1 and is connected to the central gear 2. The racks 3 are slidably arranged in the installation chamber 11 and are symmetrically distributed in the center. The two transmission racks 3 are meshed and matched with the central gear 2 , and the end of the long plate 1 away from the transmission handle 21 is provided with a movable rack 3 that matches t...

Embodiment 2

[0041]On the basis of the first embodiment, a further improvement is made. A ring cavity 22 is opened in the middle of the central gear 2 , and a plurality of meshing teeth 23 are evenly arranged on the outer surface of the central gear 2 . Inside, a pressure spring 24 is arranged between the meshing tooth 23 and the inner wall of the ring cavity 22; a push-pull electromagnet 25 is also arranged between the annular cavity 22 and the meshing tooth 23, and the pressure spring 24 is sleeved on the output shaft of the push-pull electromagnet 25. , the output shaft of the push-pull electromagnet 25 is connected with the meshing teeth 23 .

[0042] In order to better match the rehabilitation needs of different patients' fracture states, such as bone separation or overlap after fracture, and to avoid injury to patients due to excessive traction or tension, the meshing teeth 23 on the central gear 2 cooperate with the ring cavity 22 and the pressure spring 24 to prevent excessive tract...

Embodiment 3

[0047] On the basis of the first embodiment, the threaded lifting assembly includes a motor 5 and a bidirectional threaded rod 51. The bidirectional threaded rod 51 is rotatably arranged in the assembly cavity 35. The thread segments on both sides of the threaded rod 51 have opposite directions of rotation, and the two clamping plates 34 are respectively threaded with the thread segments on both sides of the bidirectional threaded rod 51 and are matched with the assembly cavity 35; Therefore, when the patient's limb needs to be clamped and fixed by the clamping plate 34, it is only necessary to control the steering of the motor 5, and then drive and control the steering of the bidirectional threaded rod 51, and cooperate with the limiting effect of the column 33 to make the two clamping The plates 34 are close to or away from each other, so as to clamp and fix the limbs of the patient, and cooperate with the auxiliary fixator to further fix the limbs of the patient, which has a...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a fracture surgery auxiliary fixing device which can effectively fix limbs of a patient and meet requirements during surgery when surgical reduction treatment is performed on the patient through the arrangement of an adjusting mechanism and a fixing mechanism; meanwhile, meshing teeth of the central gear have a protection effect, in the adjusting process and the traction process, overlarge traction force can be released to achieve the effect of protecting muscular tissue of the patient, and secondary injury of the patient in the treatment and fixing process is avoided; due to the arrangement of the angle adjusting assembly, the requirements of different treatment angles can be further met, and meanwhile self-locking can be achieved after adjustment is finished; through cooperation of the auxiliary fixator and the buffer, when a patient is fixedly clamped through the clamping plate, multiple positions of limbs of the patient can be conveniently, effectively and rapidly fixed, meanwhile, buffering protection is achieved, excessive pressure is avoided, and the requirement for rapid and effective fixing can be met through cooperation of later simple adjustment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an auxiliary fixation device for fracture surgery. Background technique [0002] Fracture refers to the complete or partial fracture of the continuity of the human bone structure due to external force or its own reasons. As a common human injury, with the development of modern medicine, its treatment methods are also more diverse and effective. Treatment is a common and effective treatment. [0003] At present, in the process of fracture surgery, in order to ensure the stability of the human body and bone structure, the fracture site is often fixed accordingly to meet the needs of surgical stability. There are many steps to connect and fix with the patient, and the subsequent adjustment is also very inconvenient. It needs to be released or forced to pull to meet the fine-tuning of the position. This not only cannot meet the needs of convenient and quick adjus...
