Abstract
A kind of laminectomy retractor with hemostatic function, belongs to orthopedic medical device technical field, and paraspinal muscle is retracted for spinal operation.Its technical scheme is：The drag hook of laminectomy retractor is rectangular frame, there are horizontal grate and vertical gratings in the rectangular frame of drag hook, horizontal grate and vertical gratings interconnection, air bag is installed on the lateral surface of the rectangular frame of drag hook, air bag is made up of two panels film, one sheet of film is pasted onto on the lateral surface of the rectangular frame of drag hook, and styptic is coated with the lateral surface of another one sheet of film, and air bag is connected by gas tube with aerating device.The utility model is the pioneering of laminectomy retractor, has broken conventional thought so that laminectomy retractor can not only complete the effect of drawing, paraspinal muscle can also be pressurizeed and be stopped blooding, this is difficult to expect according to conventional thought.The utility model is simple in construction, easy to use, Pressur hemostatic works well, so that paraspinal muscle bleeding after traction significantly reduces, reduce and remove blood operation, shorten operating time, effective technical support is provided to improve surgical quality, is worth the popularization and application in operation.
Description
Technical field
A kind of laminectomy retractor for spinal operation is the utility model is related to, belongs to orthopedic medical device technical field.
Background technology
When implementing spinal operation, the paraspinal muscle of backbone both sides is peeled off after conventional incision to appear full state chart, due to operation
Operating portion locating depth exists, often need to be by laminectomy retractor by tissue retraction by vertebra, to expose surgical field of view.It is actual in substantial amounts of operation
Shown in operation, although the use of laminectomy retractor can reach the purpose of fully exposure operating field, the paraspinal muscle of backbone both sides
Blood fortune is abundant, and behind the conventional dilator exposure visual field, paraspinal muscle oozing of blood causes surgical field of view unintelligible, in surgical procedure, clinic doctor
Life frequently uses attractor, and absorbing the blood oozed out makes field of operation get a clear view.Such case significantly extends operating time,
The unnecessary operation of doctor is added, also increases the pain of patient.Therefore, the bleeding in vertebral plate traction surgical procedure how is reduced
Amount, it is to need to solve the problems, such as to shorten operating time.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of laminectomy retractor with hemostatic function, this vertebra
Plate retractor can cause paraspinal muscle bleeding after traction to significantly reduce, and remove blood operation to reduce, shorten operating time, subtract
The pain of small patient.
Solve above-mentioned technical problem technical scheme be：
A kind of laminectomy retractor with hemostatic function, it is made up of handle, draft arm, drag hook, and two handles connect respectively
Two draft arm rear portions are connected on, are connected between two handles by rotating shaft, the front end of two draft arms is separately installed with drag hook, its
Improvements are that drag hook is rectangular frame, there is horizontal grate and vertical gratings in the rectangular frame of drag hook, horizontal grate and vertical
Grid interconnection, air bag is installed on the lateral surface of the rectangular frame of drag hook, air bag is made up of two panels film, and one sheet of film glues
It is attached on the lateral surface of the rectangular frame of drag hook, styptic is coated with the lateral surface of another one sheet of film, air bag passes through gas tube
It is connected with aerating device.
The above-mentioned laminectomy retractor with hemostatic function, the horizontal grate of the drag hook rectangular frame is by 3-5 cross bar group
Into vertical gratings are made up of 3-7 montant.
The above-mentioned laminectomy retractor with hemostatic function, the air bag and film neighboring respectively with drag hook rectangular frame
The cross bar of horizontal grate is mutually bonded with the montant of vertical gratings, while cross bar and vertical lattice of the air bag and film surface with horizontal grate
The montant of grid is mutually bonded.
The beneficial effects of the utility model are：
The utility model has redesigned the drag hook of laminectomy retractor front end, and the structure of parallel driving lever is changed into plane framework
Structure, and it is coated with styptic on a side bonds air bag relative with paraspinal muscle for plane framework, air bag lateral surface.Pass through this
The improvement of sample, air bag can carry out flexible push-and-pull and pressurization to paraspinal muscle, avoid damage to musculature and reduce bleeding, air bag side
The styptic in face causes paraspinal muscle bleeding after traction to significantly reduce.
The utility model is the pioneering of laminectomy retractor, has broken conventional thought so that laminectomy retractor can not only be complete
Into the effect of drawing, paraspinal muscle can also be pressurizeed and be stopped blooding, this is difficult to expect according to conventional thought.This practicality is new
Type is simple in construction, easy to use, Pressur hemostatic works well so that paraspinal muscle bleeding after traction significantly reduces, and reduces clear
Except blood operates, operating time is shortened, effective technical support is provided to improve surgical quality, is worth promoting in operation
Using.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the rectangular frame of drag hook；
Fig. 3 is the side view of drag hook.
Marked in figure as follows：Handle 1, draft arm 2, drag hook 3, horizontal grate 4, vertical gratings 5, air bag 6, gas tube 7.
Embodiment
The utility model is made up of handle 1, draft arm 2, drag hook 3, air bag 6, gas tube 7.
Shown in figure, two handles 1 are connected to two rear portions of draft arm 2, are connected between two handles 1 by rotating shaft
Connect, the front end of each draft arm 2 is provided with drag hook 3, has locking and connecting device between the rear portion of two handles 1, these structures with
General laminectomy retractor is identical.
Shown in figure, drag hook 3 of the present utility model is changed to rectangular frame by parallel driving lever, and rectangular frame is by horizontal grate
4 and vertical gratings 5 form, horizontal grate 4 connects with the square crossing of vertical gratings 5.The horizontal grate 4 of the rectangular frame of drag hook 3 is
3-5 cross bar composition, vertical gratings 5 are that 3-7 montant forms, and the joining of the cross bar of horizontal grate 4 and the montant of vertical gratings 5 is
Node.
Showing in figure, air bag 6 is installed on the lateral surface of the rectangular frame of drag hook 3, and air bag 6 is made up of two panels film, and one
Piece film is pasted onto on the lateral surface of the rectangular frame of drag hook 3, and styptic, air bag 6 are coated with the lateral surface of another one sheet of film
