Abstract
The invention discloses an endoscope lower thoracic vertebra body expander. The outer side of a middle shaft (5) is sleeved with a spiral sleeve (3). A movable sleeve (1) is arranged at the lower end of the spiral sleeve (3). Lugs (8) are arranged on the two sides of the movable sleeve (1) and provided with twisting shafts (9), and supporting arms (10) are arranged on the twisting shafts (9). Compared with the prior art, the expander can be placed in the chest through a minimally-invasive opening, the supporting arms are used for expanding a thoracic vertebra body fixing screw, operation is performed on the outer side of the chest through an operation handle, the problem that no proper expanders exist in endoscopic surgery for treating thoracic vertebra injuries is effectively solved, operation of the surgery is simplified, trauma of the surgery is reduced, surgery time and length of hospital stay of patients are shortened, and the endoscope lower thoracic vertebra body expander is suitable for treating thoracic vertebra injuries and lumbar vertebra injuries and is an ideal restoration assorted instrument special for minimally-invasive treatment of thoracolumbar injuries.
Description
Technical field
The invention belongs to medical instruments field, especially a kind of chamber mirror hypocentrum dilator of orthopaedics.
Background technology
Lumbar vertebra compression fracture is common vertebral fracture, traditional operation is that fracture site cone pedicle screw is carried out replacement and fixation, cone pedicle screw is because having the fixing advantage of three posts, adopted widely, operation is in the past open surgery, wound is too large, hemorrhage many, hospital stays is long, add the slight illness of patient, too increase the financial burden of patient, along with the development of surgery less invasive techniques, various less invasive techniques is also used in the operation of lumbar vertebra compression fracture, patient adopts Minimally Invasive Surgery wound little, amount of bleeding is also few, pain is little, recover fast, be obtained and applying more and more widely, Chinese invention patent ZL201220319584.5 discloses one " minimally-invasive thoracolumbar vertebral fracture repositor ", by a left side, right pliers plate, adjusting nut, adjusting screw(rod), pin, movable latch, left and right pliers grip is formed, fractured vertebral body distraction reduction is carried out fast by mini-incision passage, decrease patient suffering, but this " minimally-invasive thoracolumbar vertebral fracture repositor " is only suitable for strutting of the vertebra of the way of escape Minimally Invasive Surgery of vertebra, and be not suitable for the sick and wounded chamber mirror anterior minimally invasive hands art of Thoracolumbar disk, chamber mirror Minimally Invasive Surgery due to thoracic vertebra carries out punching to place hold-down screw and dilator from the front, side of chest, this dilator is not placed in thoracic cavity by chamber mirror passage and operates, Chinese invention patent ZL201420299361.6, also disclose " a kind of vertebrae strutting device ", dynamic support arm stretch into quiet support arm groove in, evenly distributed driving gear is provided with bottom dynamic support arm, flight is plugged in driving gear, flight is installed in rotating shaft, the bracing frame that rotating shaft is installed on quiet support arm can strut the vertebral body of patient, but this dilator can not operate at Qiang Jing Wicresoft passage, this brings very large problem also to the sick and wounded chamber mirror Minimally Invasive Surgery of Thoracolumbar disk.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of chamber mirror hypocentrum dilator, when doing the operation of thoracic vertebra compression fracture, the strutting head and can be placed on thoracic cavity by Wicresoft's mouth of dilator, be used for strutting vertebral body hold-down screw, and operating grip operates in the outside in thoracic cavity, effectively solve the problem not having suitable dilator in the sick and wounded endoscope-assistant surgery of thoracic vertebra, simplify the operation of operation, decrease the wound of operation, save the hospital stays of operating time and patient, not only be applicable to the sick and wounded treatment of thoracic vertebra, also be applicable to the sick and wounded treatment of lumbar vertebra, it is the supporting apparatus of the sick and wounded special reset of minimally-invasive treatment Thoracolumbar disk under desirable chamber mirror.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: comprise axis and screw sheel, described axis is provided with thread segment, on screw sheel socket thread segment, the axis of screw sheel lower end is provided with movable sleeve, trepanning is provided with in the centre of movable sleeve, lug is provided with in the both sides of movable sleeve, lug is provided with twisted axis, twisted axis is provided with support arm, spring is provided with in the lower end of movable sleeve, the axis of lower spring end is provided with spring retainer stake, hook is provided with in the bottom of axis, axis hands handle is provided with in the upper end of axis, screw sheel handle is provided with in the upper end of screw sheel.
As the improvement project of technique scheme, be provided with bayonet socket in the bottom of described support arm.
Compared with prior art, dilator can be placed on thoracic cavity by Wicresoft's mouth by the present invention, vertebral body hold-down screw is strutted with support arm, and operating grip operates in vitro, effectively solve the problem not having suitable dilator in the endoscope-assistant surgery of thoracic vertebra sick and wounded front road, simplify the operation of operation, decrease the wound of operation, save the hospital stays of operating time and patient, not only be applicable to the sick and wounded treatment of thoracic vertebra, also being applicable to the sick and wounded treatment of lumbar vertebra, is the supporting apparatus of reset that under desirable chamber mirror, minimally-invasive treatment breast lumbar injury is sick special.
