The purpose of this utility model is to propose a kind of ultrasonic osteotome bit that screens is arranged, can improve deep efficient, reduce operating time, reduce patient's misery, reduce doctor's labor intensity, and can accurately control cutting output and shape to bone, reduce the deep loss amount in the art, accelerate patient's recovery time.
For reaching this purpose, this utility model by the following technical solutions:
A kind of ultrasonic osteotome bit that screens is arranged, head end are provided with screens port and cutting port, and the cutting port is between the screens port, and the cutting port is spill.
The cutting port is provided with sword, and the thickness of sword is less than the thickness at screens port.
Screens port and cutting port are positioned at cutter head one side, and an end at screens port is positioned at the far-end of cutter head, and the other end at screens port is positioned at the near-end of cutter head.
Screens port and cutting port symmetry are positioned at the cutter head both sides.
The cutting port is U-shaped.
The cutting port is V-shaped.
The cutting port is the C type.
Also comprise knife bar and blade, knife bar one end connects head end, and the other end of knife bar connects blade, and by arc transition, the other end of blade arranges connecting thread between knife bar and the blade, and blade arranges positive die nut position.
Adopted the technical solution of the utility model, had following effect: 1, deep efficient is high, speed is fast, reduces operating time, reduces patient's misery, reduces doctor's labor intensity; 2, the cutter head exquisiteness is small and exquisite, can accurately control cutting output and shape to bone, reduces the deep loss amount in the art, accelerates patient's recovery time; 3, hemostasis blood coagulation effect is arranged in deep process, reduce intraoperative blood loss; 4, reduce difficulty of processing, reduced production cost.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
The main thought of technical solutions of the utility model is on the planform of ultrasonic osteotome bit.Fig. 2 is the structural representation that the ultrasonic osteotome bit of screens is arranged in this utility model specific embodiment one.Fig. 3 is the side schematic view that the ultrasonic osteotome bit of screens is arranged in this utility model specific embodiment one.Fig. 4 is the schematic top plan view that the ultrasonic osteotome bit of screens is arranged in this utility model specific embodiment one.Fig. 5 is the local structure for amplifying sketch map that the ultrasonic osteotome bit of screens is arranged in this utility model specific embodiment one.Such as Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, this has the ultrasonic osteotome bit of screens to comprise head end 1, knife bar 2 and blade 3.
Head end is provided with screens port 11 and cutting port 12, screens port and cutting port are positioned at cutter head one side, one end at screens port is positioned at the far-end of cutter head, the other end at screens port is positioned at the near-end of cutter head, the cutting port is between the screens port, the cutting port is spill, and the cutting port is provided with sword, and the thickness of sword is less than the thickness at screens port.
Knife bar one end connects head end, and the other end of knife bar connects blade, and by arc transition, the other end of blade arranges connecting thread 4 between knife bar and the blade, and blade arranges positive die nut position 5.
The connecting thread of the cutter head afterbody of this specific embodiment is connected with specific ultrasonic transducer, and tightens with corresponding spanner, again ultrasonic transducer is connected in specific ultrasonic main frame, can carry out work.
On the head end, screens port and cutting port also can symmetry be positioned at the cutter head both sides.
Fig. 6 is the local structure for amplifying sketch map that the ultrasonic osteotome bit of screens is arranged in this utility model specific embodiment two.As shown in Figure 6, the cutting port is U-shaped, and the degree of depth is darker.
Fig. 7 is the local structure for amplifying sketch map that the ultrasonic osteotome bit of screens is arranged in this utility model specific embodiment three.As shown in Figure 7, the cutting port is V-shaped.
Fig. 8 is the local structure for amplifying sketch map that the ultrasonic osteotome bit of screens is arranged in this utility model specific embodiment four.As shown in Figure 8, this cutting port is the C type, and the degree of depth is more shallow.
When operation used this that ultrasonic osteotome bit of screens is arranged, the screens port of head end was used for propping up upper edge or the lower edge of bone, and cut bone at the cutting port.Direction firmly is parallel with surface of bone or to the front upper place.In cutting process, can form a fulcrum with the screens port like this, and cut along this fulcrum.The advantage of project organization is and can plays a protective role to tissue on every side like this, and depth of cut, thickness all can be accurately controls in the cutting process.
When for example in operation, using, between the vertebral body (bone) that the screens port can be put in ridge (bone) meninges and will remove, the screens port props up bone and forms fulcrum, direction firmly is for to operate to the front upper place, do not have downward power, so just reduce the danger to the damage of ridge (bone) marrow accidental destruction, reduced operation risk, reduced operation easier.In addition the screens port also can repair the bone section scrape, housekeeping operation.
The above; it only is the better specific embodiment of this utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with the people of this technology in the disclosed technical scope of this utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
