Description
Technical field
The utility model relates to orthopedic medical device, specifically a kind of caput radii reduction forceps.
Background technique
Fracture of head of radius both can individually occur, and can also appear in " terrible triad " (fracture of head of radius, coronoid process
Fracture, the dislocation of the elbow joint) etc. in complicated fracture dislocation of elbow.Elbow fracture can influence 5 joints, and once
Elbow fracture occurs, ectopic ossification is easy around elbow joint, disability rate is high, and therefore, fracture dislocation of elbow is in orthopaedic trauma
In have special status.Existing literature shows: rebuilding Elbow Stability, early functional exercise can obtain optimal elbow and close
Save function.
The integrality of caput radii can maintain the stability of elbow lateral column, provide 40% Elbow Stability.Mesh
The therapeutic scheme selection of preceding fracture of head of radius is all based on Mason parting.Mason parting is one kind based on fracture of head of radius form
Parting, if fracture of head of radius block at 3 pieces or more, is attributed to tetra- type of Mason.Caput radii displacement is treatment tetra- type caput radii of Mason
The preferred option of fracture is treated.Although caput radii displacement have some disadvantages, i.e., can not individuation selection, it is expensive.But
If fracture of head of radius at 3 pieces or more, conventional interior fixation due to can not effectively pressurize between fracture of radius block it is fixed and
The reasons such as difficulty are held when caput radii is fixed, can not early functional exercise, good clinical effectiveness is obtained, so current caput radii
Displacement is still mainstream therapeutic scheme, considerably increases the financial burden of patient.
If the caput radii bone block for holding fragmentation can be facilitated by certain equipment or instrument, while conveniently to radius
Skull folded block is fixed, and will reduce the financial burden of patient, shortens operating time.
Utility model content
The purpose of the utility model is to provide a kind of caput radii reduction forceps, to solve the oar of fragmentation in fracture of head of radius treatment
Bone bone block can not hold fixed problem.
Purpose of the utility model is realized as follows:
A kind of caput radii reduction forceps, including the first caliper and the second caliper being hinged；First caliper is by the first folder
It holds portion and the first hand-held part is constituted；First clamping part is that the top of the first grip shank is provided with semi-cylindrical shaped clamping head,
Several through clamping head surfaces externally and internally and from the inside to the outside apertures gradually big micro-hole is offered on the semi-cylindrical shaped clamping head；
First hand-held part is that first handle end is provided with retaining ring, and a column and first handle are provided on the first handle
Direction is consistent mentions for folding；The end of first grip shank forms one by the top of articulated shaft and the first handle
Formula structure；
Second caliper is made of the second clamping part and the second hand-held part；Second clamping part is in the second grip shank
Top be provided with semi-cylindrical shaped clamping head, offered on the semi-cylindrical shaped clamping head several through clamping head surfaces externally and internally
And aperture gradually big micro-hole from the inside to the outside；Second hand-held part is that second handle end is provided with retaining ring, described
1-3 and the briar tooth mentioned and engaged are provided on two handles；The end of second grip shank by articulated shaft with it is described
The top of second handle forms integral structure.
Caput radii reduction forceps described in the utility model, first grip shank and second grip shank are arc knot
Structure.
Caput radii reduction forceps described in the utility model, the width of the semi-cylindrical shaped clamping head are greater than first clamping
The width of handle and the second grip shank is 2 ~ 3cm.
The utility model uses semi-cylindrical shaped clamping head that is with one fixed width and offering micro-hole, and width is greater than
The width of first grip shank and the second grip shank can clamp different size of caput radii, the outer width of micro-hole
The Kirschner wire that interior narrow design can be convenient 0.8-1.5 carries out the fixation of different directions, and the design of portion of the handle structure facilitates holding
With interim lock.The utility model both can be used for the reset of caput radii fragment, fixation, while can do to Radial, fibula isometric
Shaft fracture carries out interim fixation, shortens operating time.
