Description
Technical field
The invention belongs to the hysteroscope hypocentrum dilator of medical instruments field, especially a kind of orthopaedics.
Background technology
Thoracolumbar fracture is common vertebral fracture, and traditional operation is that fracture site is resetted admittedly with cone pedicle screw
Fixed, cone pedicle screw is widely used because of the advantage fixed with three posts, and conventional operation is open surgery, and wound is too
Greatly, bleeding is more, the hospital stays is long, increased the slight illness of patient, the financial burden of patient is also increased, with surgery minimal invasive techniques
Development, various minimal invasive techniques are also used in the operation of thoracolumbar fracture, and patient is small using Minimally Invasive Surgery wound, amount of bleeding
Also few, pain is small, recovery is fast, is being obtained and is increasingly being widely applied, and Chinese invention patent ZL201220319584.5 is public
A kind of " minimally-invasive thoracolumbar vertebral fracture repositor " is opened, by left and right clamp piece, adjusting nut, adjusting screw rod, pin, movable latch, a left side
Right pliers grip is constituted, and can quickly carry out fractured vertebral body distraction reduction by mini-incision passage, reduces patient suffering, but this
Kind " minimally-invasive thoracolumbar vertebral fracture repositor " is only suitable for strutting for the vertebra of the way of escape Minimally Invasive Surgery of vertebra, is not appropriate for Thoracolumbar disk wound
The hysteroscope anterior minimally invasive operation of disease, because the hysteroscope Minimally Invasive Surgery of thoracic vertebrae is to carry out punching from the side front of chest to place solid
Determine screw and dilator, this dilator can not be placed in thoracic cavity by hysteroscope passage and be operated, Chinese invention patent
ZL201420299361.6, also discloses that " a kind of vertebrae strutting device ", and dynamic support arm is stretched into the groove of quiet support arm, moves branch
Brace bottom is provided with evenly distributed sliding tooth, and flight is plugged in sliding tooth, and flight is installed in rotating shaft, and rotating shaft is installed on
The centrum of patient can be strutted on the support frame of quiet support arm, but this dilator can not be in the minimally invasive passage of hysteroscope
Operated, this also brings very big problem to the sick and wounded hysteroscope Minimally Invasive Surgery of Thoracolumbar disk.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of hysteroscope hypocentrum dilator, are doing thoracic vertebrae compression fracture
During operation, strutting head and being placed on thoracic cavity by minimally invasive mouth for dilator for strutting centrum fixing screws, and is operated
Handle is operated on the outside of thoracic cavity, and effectively solving in the sick and wounded endoscope-assistant surgery of thoracic vertebrae does not have asking for suitable dilator
Topic, simplifies the operation of operation, reduces the wound of operation, saves the hospital stays of operating time and patient, is not only adapted to
The sick and wounded treatment of thoracic vertebrae, is also suitable for the sick and wounded treatment of lumbar vertebrae, and being that minimally-invasive treatment Thoracolumbar disk is sick and wounded special under preferable hysteroscope answers
The supporting apparatus in position.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Comprising axis and screw sheel, described
Axis be provided with thread segment, on screw sheel socket thread segment, movable sleeve is provided with the axis of screw sheel lower end, in work
The centre of dynamic set is provided with set hole, and lug is provided with the both sides of movable sleeve, and twisted axis is provided with lug, and support arm is provided with twisted axis,
Spring is provided with the lower end of movable sleeve, spring retainer stake is provided with the axis of lower spring end, hook is provided with the bottom of axis,
Axis handle is provided with the upper end of axis, screw sheel handle is provided with the upper end of screw sheel.
As the improvement project of above-mentioned technical proposal, bayonet socket is provided with the bottom of described support arm.
Compared with prior art, dilator can be placed on thoracic cavity by the present invention by minimally invasive mouth, be supportted with support arm
Centrum fixing screws are opened, and operation handle is operated in vitro, effectively solve in the sick and wounded preceding road endoscope-assistant surgery of thoracic vertebrae and do not have
There is the problem of suitable dilator, simplify the operation of operation, reduce the wound of operation, save operating time and patient
Hospital stays, not only it is adapted to the sick and wounded treatment of thoracic vertebrae, is also suitable for the sick and wounded treatment of lumbar vertebrae, is minimally-invasive treatment chest under preferable hysteroscope
The sick and wounded supporting apparatus of special reset of waist.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the embodiment of the present invention 1.
Fig. 2 is the structural representation of the side-looking of Fig. 1.
Shown in figure：1 is movable sleeve, and 2 is set hole, and 3 is screw sheel, and 4 is screw sheel handle, and 5 is axis, during 6 are
Axle handle, 7 is thread segment, and 8 is lug, and 9 is twisted axis, and 10 is support arm, and 11 is bayonet socket, and 12 is spring, and 13 is spring retainer stake, 14
It is hook.
Specific embodiment
Embodiment 1：Reference picture 1- Fig. 2, is the structural representation of the embodiment of the present invention 1, and thread segment 7 is provided with axis 5,
