A kind of improved minimally invasive spine surgical drag hook, including two cross bars and two vertical poles are the utility model is related to, the cross bar and vertical pole are strip, and are equipped with a groove；The cross bar and vertical pole mutually overlap quadrangularly, and both is connected after each lap-joint passes through corresponding groove with bolt pair, or are mutually shifted both；Distraction plate is respectively equipped with the vertical pole；Connector is respectively equipped with the cross bar, can be connected with pedicle screw and fix the cross bar.The utility model is designed reasonably, it is simple in construction, provided with convenient, the pedicle screw inserted initial stage in operation can be utilized to fix this dilator, so as to no longer need the help of assistant, can avoid, because coordinating the improper and harmful effect caused by operation, creating favorable conditions to improve surgical quality, the step of simplifying MIS TLIF arts simultaneously, reduces radiation.
Description
Technical field
A kind of medicine equipment is the utility model is related to, especially one kind can be with pedicle screw in minimal invasive lumbar surgery
It is engaged and the device in the visual field needed for operation is provided, specifically a kind of improved minimally invasive spine surgical drag hook.
Background technology
In the minimally invasive intervertebral spinal fusion decompression fusion of lumbar vertebrae（That is MIS-TLIF）In, in decompression and fusion process, it is necessary to
Appear articular process part.At present, mainly combined by a kind of cast drag hook with free arm and surgical field of view is fixed on articular process
Around, but the method is not suitable for inserting pedicle screw, because cast drag hook can stop inserting for pedicle screw, typically needs
Cast drag hook is removed after decompressing fusion and inserts percutaneous cervical arc root screw under fluoroscopy again, and process is relatively complicated, and puts
Ray exposes.Therefore, so can be through Wiltse approaches, it is necessary to design a kind of self-retractor for being fixed on pedicle screw tail end
Pedicle screw is easily inserted under direct-view, then row decompression fusion again, simplifies MIS-TLIF operating procedure, reduce perspective
Number.
Utility model content
The purpose of this utility model is for the problem of currently being run into minimal invasive lumbar surgery, there is provided a kind of improved micro-
Self-retractor is created, the pedicle screw inserted initial stage in operation can be utilized to fix this dilator, so as to no longer need to perform the operation
The help of assistant, current main-stream MIS-TLIF operating procedure is simplified, reduce perspective number.
The technical solution of the utility model is：
A kind of improved minimally invasive spine surgical drag hook, including two cross bars and two vertical poles, the cross bar and vertical pole are equal
For strip, and it is equipped with a groove；The cross bar and vertical pole mutually overlap quadrangularly, and in each lap-joint's bolt pair
Both is connected after through corresponding groove, or be mutually shifted both；Distraction plate is respectively equipped with the vertical pole；The horizontal stroke
Connector is respectively equipped with bar, can be connected with pedicle screw and fix the cross bar.
Further, the bolt pair includes screw rod and hand wheel type nut, can facilitate elastic operation.
Further, the connector includes support bar and connector；The support bar is thin rod shape, and its upper end connects institute
Cross bar is stated, lower end connects the connector；The connector is cylindrical shape, can be sleeved on the end of pedicle screw.
Further, the cross bar or vertical pole are provided with cold light source lighting device；The lighting device can be distorted and rotated,
Meet operation needs.
The beneficial effects of the utility model：
The utility model is designed reasonably, it is simple in construction, provided with convenient, the pedicle of vertebral arch screw inserted initial stage in operation can be utilized
Nail fixes this dilator, so as to no longer need the help of assistant, can avoid because coordinate it is improper and caused by operation not
Good influence, created favorable conditions to improve surgical quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1- cross bars；2- grooves；3- vertical poles；4- bolt pairs；5- support bars；6- connectors；7- distraction plates；8- is illuminated
Device.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
Involved " horizontal stroke " or " vertical " sets for convenience of narration herein, special not to the restriction of the utility model structure
This explanation.
As shown in Figure 1.
A kind of improved minimally invasive spine surgical drag hook, including two cross bars 1 and two vertical poles 3.The cross bar 1 and vertical pole
3 be strip, and is equipped with a groove 2.The groove 2 can be located at the middle of cross bar 1 or vertical pole 3, in order to install
And use.The cross bar 1 and vertical pole 3 mutually overlap quadrangularly, and pass through corresponding groove 2 with bolt pair 4 in each lap-joint
After both is connected, or be mutually shifted both.The bolt pair 4 includes screw rod and hand wheel type nut, can be by screw rod under
Up through the cross bar 1 and the groove 2 of vertical pole 3, then up tightened with nut, make elastic operation more convenient.Work as pine
When opening nut, you can be mutually shifted cross bar 1 and vertical pole 3.
Distraction plate 7 is respectively equipped with the vertical pole 3, muscle that can be with the movement of vertical pole 3 and by operative region etc. pulls open,
Appeared surgical field of view.Preferably, the distraction plate 7 is sleeved on the vertical pole 3, can be moved along the vertical pole 3, so as to
Flexible adjustment position.
Connector is respectively equipped with the cross bar 1, can be connected with pedicle screw and fix the cross bar 1.Should
Connector includes support bar 5 and connector 6.Wherein, the support bar 5 is thin rod shape, and its upper end connects the cross bar 1, lower end
Connect the connector 6.The connector 6 is cylindrical shape, can be sleeved on the tail end of pedicle screw.
The cross bar 1 is provided with cold light source lighting device 8, such as the illuminating lamp of cold light source, to illuminate operative region.Enter
One step, the lighting device 8 is also rotatable and distorts, adjustment position in convenient operation.The lighting device 8 may also set up in vertical pole
On 3.
Application method of the present utility model is：In minimal invasive lumbar surgery（MIS-TLIF）In, especially carrying out lumbar vertebrae cunning
During art of slipping out of the hand, first insert pedicle screw and carry out preliminary lifting reset.Then, corresponding bolt in the utility model is unclamped
Pair, and mobile cross bar and vertical pole, enable connector to be put into surgical wound and are socketed in the tail end of percutaneous screw.Then, it is mobile
Vertical pole, drive distraction plate to strut paravertebral muscles, and bolt pair tightened, enable that distraction plate stablizes by operation field exposing
Out.Because the utility model can need flexibly to adjust the position of distraction plate according to operation, the placement that can stablize again, no
Need again assistant coordinate help, so as to effectively prevent in the past operation in because coordinate it is improper and caused by operation bad shadow
Ring, created favorable conditions to improve surgical quality.
The utility model is not directed to partly same as the prior art or can realized using prior art.
