Abstract
The utility model belongs to the design and manufacturing technology field of medical recovery therapeutic equipment, specifically disclose a kind of lower limb line of force X piece assistive devices, it is interior on fixed case to be provided with arc groove including the knee joint fixed case in case shape, it is respectively equipped with two sides of fixed case with female through hole；By being formed with externally threaded bolt and kneecap fixed plate, bolt is adapted kneecap fixed mechanism with through hole, and kneecap fixed plate is made up of arc and the level board being connected with arc.The present apparatus can effectively solve the problem that horizontal position claps the non-type problem of the x-ray lower limb line of force, easy to operation；Accurate information can be provided to pre-surgery assessment corrective surgery.
Description
Technical field
The utility model belongs to the design and manufacturing technology field of medical recovery therapeutic equipment, specifically discloses under one kind
Limb line of force X piece assistive devices.
Background technology
In bone surgery total knee arthroplasty, preoperative routine needs to improve lower limb line of force X pieces, and the lower limb line of force is accurate
Measurement has material impact to patient's postoperative function and joint prosthesis long term survival.Metering system at present：Loading by lower limbs position total length
Piece is taken the photograph, using Digital X-ray Radiotive system, erect position leans against parapodium towards bulb before and after patient bears a heavy burden（Detector）, two
Hand steered firmly support is closed up with fixation postures, both feet, and in standardized human body's erect position posture, this is that standard is made film.But in clinical work
Found in work, the patient for largely needing row knee replacements is in gerontal patient's knee joint degenerative change, is closed more in knee
Flexing Varus deformity is saved, or even patient can not stand and complete film making, now image department doctor can allow patient to lie in complete on shooting bed
Into lower limb line of force piece, cause lower limb to rotate due to patient's usually from Varus deformity, during film making, surgical procedure is assessed to operative doctor
Bring difficulty.Lie down and take the most critical requirement of limb line of force piece as knee joint kneecap upward, kneecap can subtract significantly after upward
The error of few lower limb line of force.
The content of the invention
The purpose of this utility model：A kind of lower limb line of force X piece assistive devices are designed, this assistive device can be fixed well
Kneecap, the making material of this apparatus is can pass through the material of x-ray, such as carbon fibre material, so as to ensure patient's lower limb line of force X
The shooting effect of piece.
The technical solution of the utility model：A kind of lower limb line of force X piece assistive devices, including fixed in the knee joint of case shape
Case, on fixed case in be provided with arc groove, be respectively equipped with two sides of fixed case with female through hole；Kneecap fixes machine
By being formed with externally threaded bolt and kneecap fixed plate, bolt is adapted structure with through hole, and kneecap fixed plate is by arc
And the level board composition being connected with arc.
Optimization design, it is provided with below the middle part of fixed box wall with female connecting hole, by one therewith
What is coordinated is connected with externally threaded connecting pole with another fixed case, and can rotate two fixations that further by knob
The distance between case.
Further optimization design, it is hinged above fixed case and a case lid being adapted with fixed case is set, in case lid
Groove provided with fixed kneecap.
Beneficial effect：The present apparatus can effectively solve the problem that horizontal position claps the non-type problem of the x-ray lower limb line of force, easy to operation；
Accurate information can be provided to pre-surgery assessment corrective surgery.
Brief description of the drawings
Accompanying drawing 1 is main structure diagram of the present utility model.
Embodiment
Embodiment 1, a kind of lower limb line of force X piece assistive devices, as shown in figure 1, including the knee joint fixed case in case shape
1, on fixed case 1 in be provided with arc groove 10, be respectively equipped with 1 two sides of fixed case with female through hole 11；Kneecap
By being formed with externally threaded bolt 20 and kneecap fixed plate, bolt 20 is adapted fixed mechanism 2 with through hole 11, described kneecap
Bone fixation plate is made up of arc 21 and the level board 22 being connected with arc 21, and whole instrumentation can pass through X ray
Material is made, and so can guarantee that does not influence shooting effect.
In practice, some are probably to refer to for a knee joint to perform operation, so can using a fixed case
With, but be required for performing for two joints and replace or in order to can guarantee that best shooting contrast effect can use two
Individual fixed case, fixed knee joint especially ensures that kneecap is face-up, so below the middle part of the described madial wall of fixed case 1
It is matched with externally threaded connecting pole 4 and another fixed case 1 by one provided with female connecting hole 12
It is connected, and the distance between two fixed cases 1 that further can be rotated by knob 40.
In order to ensure to have carried out after rotation promotes kneecap fixed mechanism to the kneecap of introversion to be pushed to face-up shape
State can be maintained at shooting and finish, will not move, it is necessary to be hinged above fixed case 1 set one it is adaptable with fixed case 1
Case lid 3, the interior groove for being provided with fixed kneecap of case lid 3, can so close case lid and ensure kneecap upward.
