Technical field

This utility model relates to beauty and shaping oral surgery technical field of medical instruments, and particularly a kind of medical lower jaw cuts the bone wheel resilient protection cover that rubs.

Background technology

In the medical operating of oral surgery and beauty and shaping; Section bone loose to angle of mandible generally cuts bone with the miniature electric saw or the wheel that rubs, and the miniature electric apparatus of medical angle of mandible bone comprises main frame, saw, mill with handle, switch, and the bone that cuts that is installed in the front end of handle is taken turns or saw with rubbing; And power supply is formed; Through the wheel that rubs the bony site of cutting of mandibular bone is cut a section bone, reach the ideal angle of ideal angle of mandible, thus beauty treatment; In the wheel high speed rotating process of rubbing, strand possibly occur, cut surrounding soft tissue's (comprising blood vessel, nerve etc.), but not corresponding protection measure on the wheel that rubs that provides in the prior art.

The utility model content

This utility model provides a kind of medical lower jaw to cut the bone wheel resilient protection cover that rubs, and it is simple in structure, easy to operate, can in the wheel high speed rotating process of rubbing, play a protective role to the soft tissue around the mandibular bone.

To achieve these goals, this utility model provides following technical scheme:

A kind of medical lower jaw cuts the bone wheel resilient protection cover that rubs; It comprises: circular sleeve; The side of said circular sleeve front end is provided with the strip opening; The end face of said sleeve rear end has the cylindrical opening that matches with the external diameter of polisher handle, and the end face of said circular sleeve front end is provided with a flange, and the direction of said flange protrusions direction and said strip opening is relative.

Preferably, said telescopic lateral surface is set with a cleaning pipe, and said cleaning pipe front end passes the strip opening of barrel forward end and is fixed on the said telescopic medial wall, and separate with said sleeve the rear end of said cleaning pipe.

Preferably, the rear end of said cleaning pipe is provided with anti-slop serrations.

Preferably, said telescopic front end is connected through the Elastic Steel lath with said telescopic rear end, and said sleeve is fixed on the medial surface of said Elastic Steel lath, and the front end of said cleaning pipe is positioned at the medial surface of said Elastic Steel lath.

Preferably, the external diameter of said flange is greater than the external diameter of the front end end face of said circular sleeve.

Through implementing above technical scheme, have following technique effect: the medical lower jaw that this utility model provides cuts the bone wheel resilient protection cover that rubs, and can in the wheel high speed rotating process of rubbing, play a protective role to the soft tissue around the mandibular bone, and is simple in structure, easy to operate.

The specific embodiment

In order better to understand the technical scheme of this utility model, describe the embodiment that this utility model provides in detail below in conjunction with accompanying drawing.

This utility model embodiment provides a kind of medical lower jaw to cut the bone wheel resilient protection cover that rubs; Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; This protective sleeve comprises: circular sleeve 101; The side of said circular sleeve 101 front ends 111 is provided with strip opening 102; The end face of said sleeve 101 rear ends 112 has the cylindrical opening that matches with the external diameter of polisher handle 120, and the end face of said circular sleeve 101 front ends is provided with a flange 103, and the direction of said flange 103 protrusion direction and said strip opening 102 is relative.

When cutting bone, protected mandibular bone soft tissue, blood vessel and nerve etc. on every side like this, made the wheel that rubs that is rotated in strand, when cutting; The side of front end of wheel of rubbing is the plane; This planar side be pressed in surface of bone can antifriction the rotary torsion of wheel, pressing down the wheel that rubs when cutting bone simultaneously, the front end of resilient sleeve is still on surface of bone; And the wheel that rubs can continue to cut bone downwards, and the tissue around the mandibular bone is played a protective role.

In a further embodiment; The lateral surface of said sleeve 101 is set with a cleaning pipe 104; The strip opening and 102 that said cleaning pipe 104 front ends pass barrel forward end 101 is fixed on the medial wall of said sleeve 101, and separate with said sleeve 101 rear end of said cleaning pipe 104.This cleaning pipe 104 can in time wash cuts the bone bits that grind.

In other embodiments, further, the rear end of said cleaning pipe 104 is provided with anti-slop serrations 106.

Said telescopic front end 111 is connected through Elastic Steel lath 105 with said telescopic rear end 112; And said sleeve 101 (this telescopic mid portion) is fixed on the medial surface of said Elastic Steel lath 105, and the front end of said cleaning pipe 104 is positioned at the medial surface of said Elastic Steel lath 105.

During operation,, separate under the mandibular periosteum at first in the mouth cutout; Expose angle of mandible, angle of mandible is separated with on every side soft tissue, blood vessel, neural replenishing, on mandibular bone, finish with detail pen by the bone scope of cutting that designs before the art and cut the bone line; Draw back surrounding tissue with hook, will be with this section of module alignment bone line of the easy-to-use mandibular bone polisher of this protective sleeve then, the front end of protective sleeve through after on the diaphysis of expansion section bit plane side pressure at mandibular bone; The light polisher handle of pressing, this protective sleeve is crushed on the surface of bone, and the wheel that rubs grinds deep body because of rotation to the mandibular bone direction; When lifting handle, the wheel face that rubs inserts to the protective sleeve front end, and protective sleeve can not contact with the wheel that rubs because of the location that stops of syringe pipe; Can wash the bone bits that mill scales off through cleaning pipe flushing normal saline, the temperature of the wheel that rubs can not risen, prevent that Yin Gaowen from damage the wheel that rubs and high temperature causes osteonecrosis; Powered-down after bone-culting operation is accomplished, sew up wound, wrapping, antiinflammatory are handled.

This protective sleeve is owing to a side that is provided with outwardly directed flange of internal diameter and flange at telescopic front end is the plane over against the strip open side promptly; The wheel that rubs in the operation is the rotation of in the barrel forward end of protective sleeve, working, and can prevent that surrounding tissue nerve etc. is cut damage, when grinding cut and do; Rub wheel to down cutting and the cover face of protective sleeve is pressed on the surface of bone of sclerotin; The downward mill that does not influence the wheel that rubs is cut, and simple in structure, easy to operate.

More than a kind of medical lower jaw that this utility model embodiment is provided cut the bone wheel resilient protection cover that rubs and carried out detailed introduction; For one of ordinary skill in the art; Thought according to this utility model embodiment; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to this utility model.
