Body assembling is performed the operation again, in Minimally Invasive Surgery, can be intercepted mirror visual field periphery bone or tissue, be expanded arthroscopic diagnosis model
It encloses, saves operating time, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions: osteotome is poured under a kind of foramen intervertebrale lens, including
Knife bar, described knife bar one end are equipped with cutter head, and the knife bar other end is equipped with knife handle, and fixing groove is equipped with inside the knife handle, described
Knife bar outer wall is equipped with strengthening rib strip.
Preferably, the cutter head and knife handle are integrally formed with knife bar.
Preferably, the fixing groove is set as ball race or anchor channel-shaped.
Preferably, the quantity of the strengthening rib strip is set as multiple, and multiple strengthening rib strips are evenly distributed in knife bar
Portion's outer wall.
Preferably, the cutter head width is greater than knife bar width.
The technical effect and advantage of the utility model:
1, the utility model is suitable for existing medical treatment and sets by being equipped with knife handle and fixing groove, multifarious fixing groove design
Multifarious handle connection, facilitates the operation of healthcare givers, cutter head is made of multiple angles, is applicable in different operations in standby
The operation of appearance, suitable for affected area cut or strike off, the osteotome of more traditional single form, be capable of providing it is more convenient, have
The operation of effect, after cutter head width increase, knife bar is passed through by foramen intervertebrale lens bottom end, and after reaching foramen intervertebrale lens head, handle is led to
It crosses fixing groove to connect with knife handle, the overall package for completing osteotome is performed the operation again, in Minimally Invasive Surgery, can intercept the mirror visual field
Periphery bone or tissue expand arthroscopic diagnosis range, save operating time；
2, the utility model can be increased between knife bar and camera lens vias inner walls by being equipped with the setting of strengthening rib strip, strengthening rib strip
Frictional force, prevent in surgical procedure because knife bar occurs to break away injury to surgery location caused by the displacement occurred, and reinforcing rib
The setting of item can reinforce the stress intensity of knife bar, prevent osteotome from occurring the case where knife bar fracture in use, to increase
The service life of the osteotome.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model, which provides, pours osteotome, including knife bar 1, the knife under a kind of foramen intervertebrale lens as shown in figures 1-8
1 one end of bar is equipped with cutter head 2, and 1 other end of knife bar is equipped with knife handle 3, is equipped with fixing groove 4, the knife bar 1 inside the knife handle 3
Outer wall is equipped with strengthening rib strip 5.
Further, in the above-mentioned technical solutions, the cutter head 2 and knife handle 3 are integrally formed with knife bar 1, the cutter head 2
It is set as doctor-like, sharp knife shape, perching knife shape or tortuous knife-like, cutter head 2 to be made of multiple angles, is applicable to different operation contents
Operation, suitable for affected area cut or strike off, the osteotome of more traditional single form, be capable of providing more convenient, effective
Operation；
Further, in the above-mentioned technical solutions, the fixing groove 4 is set as ball race or anchor channel-shaped, diversity
Fixing groove 4 design, be suitable for multifarious handle connection in existing Medical Devices, facilitate the operation of healthcare givers；
