Abstract
The invention discloses a condylar fracture reduction device with a navigation auxiliary function. The condylar fracture reduction device with the navigation auxiliary function comprises a head and a handle, wherein the top end of the head is in the shape of a fork with an opening; the top end of the handle is connected with the bottom end of the head; a navigation seat for placing a navigation ball is arranged at the bottom end of the handle; and a holding part for an operator to hold is arranged on a side of the handle. Risks of extra operative wound and facial nerve injury are reduced, meaningless operative wound and excessive separation are avoided, and damage risks of nerves and blood vessels are reduced. Meanwhile, the idiomatical prolate shape of the conventional vessel clamp or condylar reduction forceps is changed, the basic state of an ascending limb decoherence apparatus is used, an arc-shaped fork structure is designed again according to the anatomical shape feature of a mandibular condyle, and reduction of condylar fracture, particularly inwards shifted condylar fracture, can be carried out effectively. The condylar fracture reduction device with the navigation auxiliary function is relatively simple to operate and easy to popularize.
Description
Technical field
The present invention relates to a kind of medical auxiliary apparatus, more particularly to a kind of condylar fracture with navigation miscellaneous function
Restorer.
Background technology
Condyle fracture of mandibles is one of most commonly seen classification of fracture of oromaxillo-facial region, its incidence can account for it is all under
The 25%~50% of jaw fracture.Its clinical manifestation is the dysfunction and occlusal disturbance of mandibular, not in time or unreasonable
Treatment can cause including arthrocleisis and development of mandible it is abnormal etc. including severe complication.In recent years, with operation water
The continuous improvement of flat and rigid internal fixation technology, many scholars start to tend to more serious to wherein quite a few displacement
Case carry out operative treatment.
Generally needed during operative reduction using open otch exposure sclerite, and it is resetted.To fracture
The exposure of block relies primarily on preoperative auxiliary examination (such as CT) and experience and the judgement of operative doctor；And generally adopted in reseting procedure
With the prominent reduction forceps of conventional condyle, or common vessel forceps.
Because condyle is dashed forward, itself institutional framework is more special, and the difference and external force of individual patients act on lower jaw in addition
Size direction during bone is also different, seems extremely difficult when being positioned with to sclerite position.In order to position and cruelly
Undisguised folded block, operative doctor sometimes has to prolonged incison and is peeled off extensively, and do so not only result in surgical scars more
Plus substantially, while also greatly increases the risk for damaging the important anatomy structures such as facial nerve and blood vessel.
The locking teeth of the prominent reduction forceps of common condyle and vessel forceps extraordinary can not advance by leaps and bounds to go to condyle and clamp, particularly right
Even more so for some inwardly displaced condylar fracture blocks, for such case, operative doctor is had to spend very big
Strength dashes forward the clamping of itself in case coming off for sclerite for condyle.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of prominent bone of condyle with navigation miscellaneous function
Folding restorer, can effectively position condylar fracture position, reduce wound.
The present invention is achieved by the following technical solutions, and the present invention includes head and shank, and the top of the head is
Fork-shaped with opening, the top of the shank connects the bottom of head, and the bottom of the shank is provided with for placing navigation ball
Navigation seat, the side of the shank is provided with the grip part gripped for operator.
The top of the shank and the bottom of head are bolted.Head can be after use replaced and cleaned, it is ensured that
Health care.
The head is arcuate structure.Arcuate structure can directly act on sclerite, and bone is carried out by the thrust of patient
The reset of folded block.
The arc is major diameter 15mm, the oval half along major diameter direction of minor axis 10mm.The design length of arc can
Meet the need for resetting, and the radian of human mouth matches.
The navigation seat of the bottom of the shank is bolted navigation ball.Can be aided in using existing airmanship
Effectively position the position of condylar fracture.
The navigation seat is screwed cylindrical structure.Can be used for fixed navigation ball.
The present invention has advantages below compared to existing technology：Can be aided in using airmanship in operation using the present invention
Effectively the position of positioning condylar fracture block, greatly reduces the difficulty for finding searching condylar fracture block in art, improves operation effect
Rate.Reduce the risk of extra operation wound and facial nerve injury, it is to avoid meaningless operation wound and excessive separation, reduce
The damage risk of nerve and blood vessel.The moulding of conventional vessel forceps or the usual prolate of the prominent reduction forceps of condyle is changed simultaneously, is turned
And using the grown form of ascending branch elevator, according to the dissection profile feature that condyle is dashed forward, the prong like of arc has been redesigned, energy
Enough effectively to carry out condylar fracture, the especially reset of inwardly displaced condylar fracture is operated relatively easy, it is easy to promote.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the upward view of Fig. 1.
Specific embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out under premised on technical solution of the present invention
Implement, give detailed implementation method and specific operating process, but protection scope of the present invention is not limited to following implementations
Example.
As depicted in figs. 1 and 2, the present embodiment includes head 1 and shank 2, and the top of the head 1 is the fork with opening
Shape, the top of the shank 2 connects the bottom of head 1, and the bottom of the shank 2 is provided with the navigation seat for placing navigation ball
21, the side of the shank 2 is provided with the grip part 22 gripped for operator.
The top of shank 2 and the bottom of head 1 are connected by bolt 3.Head 1 can be after use replaced and cleaned, it is ensured that
Health care.Head 1 is arcuate structure, is the arc in major diameter 15mm, the oval half along major diameter direction of minor axis 10mm, and oral cavity
Degree matches.Arcuate structure can directly act on sclerite, and the reset of sclerite is carried out by the thrust of patient.Shank 2
The 21 of bottom connect navigation seat 21 by bolt 3, and navigation seat 21 is screwed cylindrical structure.Existing navigation can be utilized
Technology come aid in effectively position condylar fracture position.
When using, doctor is hand-held on the grip part 22 of shank 2, and navigation ball is rotated and drives whole restorer movement, arc
Head 1 act directly on fractures, then promote fracture site reset.Can be combined with airmanship, so as in hand
The effective position of positioning condylar fracture block in art, reduces the risk of extra operation wound and facial nerve injury；Change simultaneously
The pattern for resetting, reduces the difficulty of reset, improves procedure efficiency.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
