Background technology
Along with the quickening of social rhythm,, the change of the aggravation of the trend of aging and Working Life mode, hyperostosis has generated a kind of commonly encountered diseases and frequently-occurring disease, and is constantly tending towards rejuvenation.Medically, usually adopt the therapeutic modality of massage, acupuncture, traditional Chinese medical herbal treatment, western medical treatment and operative treatment.The method of expectant treatment can alleviating pain, but can not effect a radical cure thoroughly, and outbreak, brings a lot of miseries to patient repeatedly.If employing Drug therapy, also can produce some complication and side effect.Operative treatment is not the first-selected therapeutic modality for the treatment of hyperosteogeny, but when selecting, expectant treatment is invalid and the state of an illness is heavier, have a strong impact on patient while living, and wants to break away from misery, must carry out operative treatment.Traditional operative treatment mode has a lot of shortcomings, for example: wound is larger; Operation process brings larger misery to patient; Wound is not easy healing; Operation risk is larger etc.Minimally-invasive treatment is a kind of common methods for the treatment of at present hyperosteogeny.
In Minimally Invasive Surgery, rotary-cut bone file is indispensable instrument, and existing peeling knife rotary-cut sword is shorter, and work efficiency is lower, and chip removal function is poor.In addition, existing rotary cutter end is sharper, easily injures other organ or tissue, must extreme care in the time of use.Existing peeling knife is when for intervertebral foramina plasty, and efficiency is low, and more dangerous, easily injured nerve tissue.
Utility model content
This utility model is to provide a kind of medical rotary incision bone file, and it has chip area can discharge bone bits smoothly, has in addition defencive function, can guarantee the safety of operation.
The technical solution of the utility model: this utility model is to provide a kind of medical rotary incision bone file, comprises knife bar and rotary handle, and one end of knife bar is provided with rotary-cut cutter head, and the other end is provided with knife bar holder, and knife bar is connected with rotary handle by knife bar holder; Rotary-cut cutter head is blunt nosed, and rotary-cut cutter head is provided with and revolves file sword and chip area.Chip area is set and can be more convenient for discharging bone bits.
In aforesaid medical rotary incision bone file, the end of rotary-cut cutter head is that hemispherical is blunt nosed or elliposoidal is blunt nosed.Bone file is arranged to blunt nosed can playing a protective role, even the end of overexertion cutter can not injure Organ and tissue around yet in art.
In aforesaid medical rotary incision bone file, the end of rotary-cut cutter head is provided with annular lead-over groove.The object that annular lead-over groove is set is also for better chip removal.The active length cutting is controlled simultaneously
In aforesaid medical rotary incision bone file, knife bar is provided with rule.The precision that rule can improve operation is set, makes having higher success rate of operation.Can coordinate the use of stop, effectively control dynamics simultaneously.
In aforesaid medical rotary incision bone file, between rotary-cut cutter head and knife bar, be provided with lead-over groove.
In aforesaid medical rotary incision bone file, the length of described rotary-cut cutter head is 5mm～40mm.The length of rotary-cut cutter head is increased, and handling better when cutter is used, rotary-cut effect is better.
In aforesaid medical rotary incision bone file, described in revolve file sword the hand of spiral be left-handed.
In aforesaid medical rotary incision bone file, described in revolve file sword the hand of spiral be dextrorotation.Because human body Endoskeleton structure is comparatively complicated, therefore need to according to the structure of skeleton select to adopt left-handed revolve file sword or dextrorotation revolve file sword.
In aforesaid medical rotary incision bone file, the diameter of described knife bar is 2mm～15mm.
In aforesaid medical rotary incision bone file, also comprise hollow passageway, described hollow passageway is through knife bar holder, knife bar and rotary-cut cutter head.Hollow passageway is set and can be used for penetrating seal wire, realize precise positioning.
Compared with prior art, this utility model can effectively be discharged the bone bits that cut away by chip area is set, and by growth, revolves file sword, and handling better when cutter is used, rotary-cut effect is better.Because the end of this utility model cutter is set to blunt nosedly, therefore played the effect of effective protection peripheral organs and tissue, make to perform the operation safer.
