Description

An external non-invasive sustainable stretching device for three-dimensional correction of scoliosis deformity

technical field

The invention relates to the field of medical devices, in particular to an external non-invasive sustainable stretching device for three-dimensional correction of scoliosis deformity.

Background technique

The treatment of scoliosis is extremely challenging, especially in pre-maturity adolescent scoliosis, scoliosis with pelvic deformity, and various types of severe scoliosis. Various traditional non-surgical treatments have extremely poor results. No matter which surgical treatment method is based on sacrificing movable joints, the longitudinal sequence structure of the spine is restored as much as possible to achieve the purpose of orthopedics, and the operation is extremely difficult and the risk is relatively high. High, most of the top three hospitals are even difficult to popularize.

Due to the complexity of scoliosis, a single treatment modality is not suitable for all patients. How to choose an appropriate correction method according to the location and degree of deformity is still an unsolved problem. For adolescent idiopathic scoliosis (AIS), mild cases (Cobb angle of 10-40 degrees) can be treated with braces, but there are still many gaps in the current research on brace technology, such as the correction of vertebral body rotation, The specific size and direction of the orthopedic force, the dynamic adjustment of the correction plan, and the optimization of the ergonomic design of the brace, etc., the correction effect of the brace is not good; for severe patients (the Cobb angle is greater than 40 degrees), non-fusion surgical techniques are their treatment. The core content of the development direction is to achieve the purpose of orthopedics by applying longitudinal and sustainable stretching force to the spine. For severe rigid patients and adult patients with severe scoliosis, external stretching combined with internal fixation is also the current development trend. By stretching before internal fixation surgery, the rigid and curved spine can be relatively soft and straightened, and the nerve and vascular tissue can gradually adapt to the changes, thereby reducing the risk and difficulty of surgery. Current sustainable stretching techniques are divided into in vivo stretching devices and extracorporeal stretching devices. In vivo devices, such as various growth rod technologies, are difficult to operate, require extremely high technical requirements, and require expensive materials. Periodic surgical incision and stretching are required, and there are accidental risks such as broken rods and internal components falling off. It is difficult to popularize and is only suitable for Human immature patients with early-onset congenital scoliosis. External sustainable stretching devices, represented by various Halo traction techniques, are traumatic operations, requiring metal needles to be implanted into human bones, and steel needles to be implanted into the skull at the upper end. There is a risk of serious craniocerebral injury. The overall stretching force in the skull is limited, and it will also bring many other related complications, such as needle tract infection, loosening, cranial nerve palsy, etc., which affect the efficacy of traction and increase the cost burden of patients, which cannot be recognized by most scholars. Widespread use. Therefore, a non-invasive, slow longitudinal and sustainable stretching technique is currently needed to achieve the purpose of three-dimensional correction of scoliosis deformity.
