As further improvement of the utility model, head that described billhook includes being positioned at far-end and proximally-located cutter
Body, described blade connects handle of a knife, and described cutter groove is arranged on blade.
As further improvement of the utility model, the head circle of described billhook is blunt.
As further improvement of the utility model, described functional unit includes button, and one end of described traction element is even
Connecing button, the other end connects cutting blade, and described handle is provided with gathering sill, the inner chamber of described gathering sill connection handle edge
The length direction of handle of a knife is arranged, and in described button is slidably installed in gathering sill and passes gathering sill from intracavity of handle.
As further improvement of the utility model, also including elastic component, one end of described elastic component is fixing connects handle
The wall of inner chamber, the other end is fixing connects button, and after the depressed power of button, button is applied to press the anti-of pressure by described elastic component
Power.
The beneficial effects of the utility model are: cutting blade of the present utility model is hidden in billhook, is chosen by ligament for this
Ligament will not be produced compressing and cutting when rising, and functional unit only just can be used after aligning cutting part to control cutter
Sheet passes cutter groove relatively cutter groove sliding to realize the excision of ligament, thus is substantially reduced operation risk, and also reduces and execute
The requirement of art doctor so that posterior longitudinal ligament resection operation is easier to popularize.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is this utility model cut state schematic diagram；
Fig. 3 is the enlarged diagram of part A in Fig. 1；
Fig. 4 is the enlarged diagram of part B in Fig. 2；
Fig. 5 is the upward view of billhook；
Fig. 6 is the side view of handle.
Detailed description of the invention
Cervical posterior longitudinal ligament device for excising as shown in Figure 1, including handle of a knife 1, billhook 2 and handle 3.Handle of a knife 1 is hollow knot
Structure, its front end connects billhook 2, and the rear end of handle of a knife 1 connects handle 3.Billhook 2 is that the arc tilted also and forms folder between handle of a knife 1
Angle.With reference to Fig. 1 and Fig. 5, billhook 2 is hollow-core construction, is provided with cutter groove 21, the extension side of cutter groove 21 at it towards the inner side of handle 3
To consistent with billhook 2, it is arc, connects with billhook 2 inside.Hide in billhook 2 and be provided with cutting blade 4.Such as Fig. 2 and Fig. 4 institute
Showing, this cutting blade 4 can stretch out cutter groove 21 under the effect of external force from the inside to the outside, and slides on cutter groove 21.Referring to figs. 1 to
Fig. 4, described handle 3 is provided with functional unit, and functional unit connects cutting blade by the traction element being arranged in handle of a knife 1
4, use functional unit that cutting blade 4 can be driven to pass cutter groove 21 sliding on cutter groove 21.
Therefore, ligament, when carrying out posterior longitudinal ligament resection art, can be chosen by the device for excising in embodiment first with billhook 2
Rise, do not contact ligament in now cutting blade 4 is hidden in billhook 2, after finding correct position, execute patient use functional unit,
Control cutting blade 4 pass cutter groove 21 and oppress ligament, be continuing with functional unit afterwards and control cutting blade 4 sliding, thus
Ligament is produced dissection.
It is further preferred that billhook 2 includes head 22 and proximally-located blade, the blade connection handle of a knife being positioned at far-end
1, cutter groove 21 is arranged on blade.By said structure, there is between the head 22 of cutter groove 21 and billhook 2 a certain distance and not
Being to extend to billhook head 22, this segment distance provides billhook 2 and provokes the space of ligament.
It is further preferred that head 22 circle of billhook is blunt, in its detection with find during posterior longitudinal ligament human body group
The degree of injury knitted is preferably minimized.
In embodiment, functional unit includes button 5, and traction element generally hard material is made, and is such as to have certain thickness
The bonding jumper 6 of degree.With reference to Fig. 1 and Fig. 6, one end of bonding jumper 6 connects button 5, and the other end connects cutting blade 4.Set on handle 3
Be equipped with gathering sill 31, gathering sill 31 connect handle 3 inner chamber and along handle of a knife 1 length direction arrange, button 5 is slidably installed in gathering sill
In 31 and pass gathering sill 31 from handle 3 inner chamber.Bonding jumper 6 can be driven to deviate original position by pressing button 5 and to cutter groove
21 direction translations, then, bonding jumper i.e. drives cutting blade 4 to pass cutter groove 21, as shown in Figure 2 and Figure 4；Now, patient is executed again
Operation button 5 is along gathering sill 31 sliding downward, then bonding jumper moves down, and drives cutting blade 4 to cut downwards.Execute
Patient can also be by moving down the effect that handle 3 reaches similar or identical.Certainly, the moving down not of above-mentioned button 5
One is set in diagram straight down, and can be an angle with vertical direction.
Preferably, with reference to Fig. 1 and Fig. 2, the device for excising in embodiment also includes elastic component, such as a helical spring 7.
The wall connecting handle 3 inner chamber is fixed in one end of spring 7, and the other end is fixing connects button 5, elastic after the depressed power of button 5
Part applies to press the counter-force of pressure to button 5, and this counter-force enables to press pressure and cancels automatically reseting of rear button 5.
The above be this utility model preferred embodiment, it is not intended that this utility model protection domain
Limit.
