Description
Technical field
This utility model belongs to medical instruments field, especially a kind of chamber mirror hypocentrum prelum of orthopaedics.
Background technology
Thoracolumbar disk is sick and wounded is the common illness of orthopaedics, 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 that Thoracolumbar disk is sick and wounded, 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, existing treatment vertebral body prelum can not operate under the chamber mirror of patient, be only suitable for the open surgery of vertebra, this brings very large problem also to the chamber mirror Minimally Invasive Surgery of Thoracolumbar disk illness.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of chamber mirror hypocentrum prelum, when doing the operation of thoracic vertebra illness, the head of prelum can be placed on thoracic cavity by Wicresoft's mouth, be used for pressurizeing to vertebral body hold-down screw, and operating grip operates in vitro, effectively solve the problem not having suitable compressor in thoracic vertebra illness endoscope-assistant surgery, 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 pressurization under the mirror of thoracic vertebra sick and wounded chamber, also be applicable to the pressurization under the mirror of lumbar vertebra sick and wounded chamber, it is the supporting apparatus of special reset of desirable chamber mirror minimally-invasive treatment Thoracolumbar disk illness.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: include axis and screw sheel, described axis is provided with thread segment, on screw sheel socket thread segment, be provided with screw sheel head in the bottom of screw sheel, be provided with movable sleeve in the lower end of screw sheel head, trepanning is provided with in the centre of movable sleeve, be provided with twisted axis in the bottom of axis, twisted axis be provided with in splay support arm, be provided with bending section in support arm lower end.
As the improvement project of technique scheme, be provided with bayonet socket in the bottom of described bending section.
Compared with prior art, the head that struts of dilator can be placed on thoracic cavity by Wicresoft's mouth by this utility model, be used for strutting vertebral body hold-down screw, and operating grip operates in vitro, effectively solve the problem not having suitable prelum in thoracic vertebra illness endoscope-assistant surgery, 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 pressurization under the mirror of thoracic vertebra sick and wounded chamber, also be applicable to the pressurization under the mirror of lumbar vertebra sick and wounded chamber, it is the supporting apparatus of special reset of desirable chamber mirror minimally-invasive treatment Thoracolumbar disk illness.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is the structural representation of this utility model embodiment 1.
Fig. 2 is the side-looking structural representation of Fig. 1.
Shown in figure: 1 is movable sleeve, 2 is trepanning, and 3 is screw sheel head, and 4 is screw sheel, and 5 is screw sheel handle, and 6 is axis, and 7 is axis handle, and 8 is thread segment, and 9 is twisted axis, and 10 is support arm, and 11 is bending section, and 12 is bayonet socket.
Detailed description of the invention
Embodiment 1: with reference to Fig. 1-Fig. 2, for the structural representation of this utility model embodiment 1, axis 6 is provided with thread segment 8, screw sheel 4 is socketed on thread segment 8, rotary sleeve handle 5 is provided with in the upper end of screw sheel 4, screw sheel head 3 is provided with in the bottom of screw sheel 4, movable sleeve 1 is provided with in the lower end of screw sheel head 3, trepanning 2 is provided with in the centre of movable sleeve 1, axis handle 7 is provided with on the top of axis 6, twisted axis 9 is provided with in the bottom of axis 6, twisted axis 9 is provided with in splay support arm 10, in the lower ends bent portion 11 of support arm 10, bayonet socket 12 is provided with in the bottom of bending section 11.
During use, at the thoracic cavity side opening Wicresoft mouth of thoracic vertebra illness patient, by chamber mirror, vertebral body hold-down screw is fixed on the healthy vertebral body at disease vertebra two ends, the splayed end of prelum is goed deep in the thoracic cavity of patient, operating grip stays the outside in thoracic cavity, splayed support arm 10 is stuck in the outside of two cone pedicle screw, bayonet socket 12 is stuck on the spreader of cone pedicle screw, by rotating screw sleeve handle 5 to thoracic vertebra pressurization, thoracic vertebra is resetted, fixes vertebral body hold-down screw, operate very convenient, the wound of patient is little, and amount of bleeding is few, recovers fast.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from this utility model creation design; can also make some changes and improvements, these all belong to protection domain of the present utility model.
