Problems solved by technology

[0005] In view of the above existing problems, the problem to be solved by the present invention is to provide a minimally invasive fixation and reinforcement device for orthopedic fractures, which is especially suitable for minimally invasive fixation and reinforcement after fracture surgery or secondary fracture surgery, and solves the problem of rigid fixation such as nails and plates. There is a problem that fracture fixation cannot be performed without a suitable focus point; at the same time, for operations that must use rigid fixation such as nail plates, less or no rigid fixation medical devices such as nail plates can be used for surgery. Low Surgical Fixation and Reinforcement Devices

example 1

[0058] Such as Figure 9 : Use the reinforcing device of the present invention alone to carry out minimally invasive fixation of fractures.

[0059] Operation name: fixation of diaphysis fractures during artificial joint replacement.

[0060] Surgical prerequisite: When the patient undergoes artificial joint replacement surgery and implants the artificial joint 4-1, a partial fracture of the femoral shaft 4-2 occurs, and the fracture must be fixed. Fixation with steel nails and plates is not suitable here. The invention fixes the fracture site of the leg shaft 4-2.

[0061] The steps to implement this fixation operation are as follows:

[0062] Step 1: The operation requires the guide 1 to pass through the middle of the bone tissue and the muscle tissue, so select the guide 1 with the sharp end 1-1 at the front end, and pass the reinforcement belt 2 through the tail ring 1-2 of the guide 1 to form a reinforcement belt 2 for boot 1.

[0063] Step 2: At the fracture site, pa...

example 2

[0069] Such as Figure 10 The bone tissue is fixed by using the reinforcing device of the present invention together with the steel nail and the steel plate system.

[0070] Operation name: Fixation of fixed plate and spinal arch in spinal fixation.

[0071] Surgical prerequisite: The steel plate 5-2 and a few steel nails have been fixed to the spinal bone. The spinal bone is composed of multiple vertebrae 5-1, and the vertebrae 5-1 are small, fragile and easy to break, so it is not suitable to perform multiple steel nail fixation , so as not to cause fractures that cannot be repaired again. The invention can be used to fix the spine safely and effectively in conjunction with the plate and nail combination.

[0072] The steps to implement this fixation operation are as follows:

[0073] Step 1: The operation requires the guide 1 to pass through the middle of the vertebral arch and the spinal cord, so select the guide 1 with the front end 1-1 as the blunt end, and pass the r...

Abstract

The invention provides a bone-fracture minimally-invasive fixation strengthening apparatus comprising a guiding unit, a strengthening belt and a strengthening gun. The rear end of the guiding unit is arranged to be a groove or a ring so as to carry the strengthening belt to penetrate bone and other tissues, and the strengthening belt penetrating the bone and the tissues is firmly fixed to the surface of the bone tissue surface or the steel plate surface to repair fracture sites through the strengthening gun. The bone-fracture minimally-invasive fixation strengthening apparatus has the advantages that low damage is caused to the tissues by adopting the minimally-invasive fixation strengthening apparatus, in particular, fixation of positions of weak bone tissues is not suitable for being fixed through nail-board combinations and the like, and the apparatus can serve as an auxiliary fixation unit used for the surgical procedure; the bone-fracture minimally-invasive fixation strengthening apparatus is simple in operation and stable in fixation, and risk of refracture after fixation is greatly reduced; meanwhile, use amount of medical instruments and apparatus of high-value material nail boards and the like is reduced, patient's financial burden and burden of social health insurance are alleviated, and the bone-fracture minimally-invasive fixation strengthening apparatus is worthy of clinical promotion and use.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a minimally invasive fixation and reinforcement device for orthopedic fractures, in particular to a minimally invasive fixation and reinforcement device for fracture operations or secondary fracture operations. Background technique [0002] As we all know, the movement of bone tissue is achieved by the pulling force of muscles and ligaments. Ligaments have high-strength toughness and moderate ductility, and drive bones to move through moderate traction. If fracture surgery can achieve minimally invasive fixation and reinforcement through a highly wear-resistant and high-toughness material, it will greatly benefit fracture patients. [0003] At present, in orthopedic surgery, plate nails, intramedullary nails and various shapes are often used in orthopedic surgery procedures such as the fixation of the greater trochanter of the leg, artificial joint replacement or replacement of the ...
