Problems solved by technology

However, the conditions of patients are diverse and complicated, and the location, degree, and type of fracture are also varied. The above-mentioned reducer is effective for conventional and common intermediate fracture positions, while for unconventional fractures, the reducer The adjustment space is too small, and the adaptability is insufficient; in addition, when the above-mentioned resetter uses various types of functional parts, due to the problem of its own coaxial structure, its expandability is poor and it is inconvenient to use and operate

Embodiment 1

[0050][Example 1] Basic structure

[0051] Such as Figure 1-3 Shown, a kind of universal fracture reduction and fixation device is characterized in that:

[0052] The fixing device includes a base, a handle, a hook, and a rod; the base is in the shape of a long column and has at least two axially through holes; the structure of the base is referred to as " "Base" is intended to highlight that the basic function of the base is to provide assembly support for hooks, rods and other devices, and as a basic structure for medical staff to hold and apply force. It is shaped like a cylinder, tube, etc. Therefore, the base The seat is not limited in specific shape, etc., as long as it can realize the above-mentioned functions, it can be called a base.

[0053] The handle is set on one end of the base for the user to hold. The handle is usually set on the outer wall of the base, one end, or integrated with the base. The surface is usually covered with polymer materials such as rubber...

Embodiment 2

[0063] [Example 2] Hook square

[0064] Such as Figure 4 , 5 As shown, on the basis of the above-mentioned embodiments, the hook in this embodiment is in the shape of a flat square column, the cross-section of the hook is in a flat rectangle, and the hook and the second through hole are fitted with a gap. The function of the hook is to directly contact and fix the fracture end. The hook in the above embodiment is mainly circular in cross-section, which is characterized in that the overall instrument size is small, which is convenient for insertion into the patient's body, and secondary damage caused by the operation of the fracture end. The wound surface is small, but it also has shortcomings, such as the small contact area and point contact between the inner side of the hook and the fracture end, which may easily cause slippage and may cause greater damage. Therefore, in this embodiment, a flat square hook is designed, which is in surface contact with the fractured end and...

Embodiment 3

[0066] [Example 3] Square hollow rod

[0067] Such as Figure 4 , 5 As shown, on the basis of the above-mentioned embodiments, the hollow rods described in this embodiment are in the shape of a flat square column or a square, specifically referring to that the outer wall sections of the outer rod and the inner rod are flat rectangular or square, and the inner wall cross-section of the outer rod is in the shape of Flat rectangular or square, the inner wall section of the inner rod is circular. As a result, the outer layer of rods can be compatible with the requirements of the flat belt of the hook, and can also be matched with other circular rods through the middle layer of rods, and the universality of the fixing device is better.

Abstract

The invention belongs to the technical field of medical auxiliary instruments, and particularly relates to a universal fracture reduction fixing device. The adjusting space of the restorer is too small, so that the adaptability is insufficient; in addition, when various types of functional parts are used by the restorer, due to the problem of a coaxial structure of the restorer, the expansibility of the restorer is poor, and the restorer is inconvenient to use and operate. The fixing device comprises a base, a handle, a hook piece and a rod piece. The hollow rod piece comprises an outer rod and an inner rod, and the outer diameter of the inner rod is smaller than the inner diameter of the outer rod; the hook piece comprises an arc-shaped section and a straight section, and an angle with a certain threshold value is formed between the arc-shaped section and the straight section. The fracture reduction fixing device is labor-saving, simple and convenient to operate, greatly reduces the difficulty of a fracture reduction operation, can reduce periosteum stripping and blood supply damage, improves the reduction precision, facilitates fracture healing, relieves the pain of a patient, facilitates subsequent installation of a bone fracture plate, and meanwhile, enables the application of a percutaneous minimally invasive internal fixation technology to be simpler and more convenient.

Description

technical field [0001] The invention belongs to the technical field of medical aids, in particular to a universal fracture reduction and fixation device. Background technique [0002] The concept of internal fixation of traumatic orthopedic fractures has developed from the concept of AO (ArbeitFuerOsteosynthese; Association for the study of internal fixation, internal fixation research society) to the current popular BO (Biological Osteosynthesis, biological fixation). combined with osteosynthesis) concept. The basic principles of fracture treatment are fracture reduction, fixation, and rehabilitation. Modern minimally invasive orthopedics advocates that fracture patients have less iatrogenic injuries, faster healing, and fewer complications. Minimal trauma and obedient, stable reduction and internal fixation are a good start for fracture healing, and patients will have early functional exercise, early recovery, and return to their original life and work positions. [0003...
