Description
Technical field
The utility model relates to medical instruments field, especially a kind of Tibial osteotomy guiding protector.
Background technique
Knee joint osseous arthritis (osteoarthritis, OA) is a kind of denaturation, destruction and bone with knee cartilage
The chronic degenerative bone and joint diseases that matter hyperplasia is characterized, shin bone deformity, line of force deflection cause knee joint osseous arthritis
One of Important cause of disease.
Proximal ends of tibia Osteotomy is used for the operative treatment of osteoarthritis.Knee joint osteoarthritis often can be with out knee
Or deformity in knee, and generate the change of intra-articular prudent stress distribution.HTO be on the inside of generally acknowledged at present treatment knee joint between
The safe and effective method of room Osteoarthritis and Varus deformity.Reach correct deformity by osteotomy, change the weight bearing line of force of suffering limb,
The stress distribution unevenness on knee joint is corrected, weight bearing is transferred to undamaged compartment, mitigates the symptom of Osteoarthritis, subtracts
The process of slow joint degeneration adjusts the lower limb line of force by correction Varus deformity, and then relieves pain, repairs knee joint, improves
Patients ' life quality, protect the minimally invasive system operation of knee be through tibial medial it is appropriate cut saw and strut bone notch, artificial bone is filled out
It fills and is fixed with bone plate bone nail, use the biomethanics axis of orthotic knee joint varus.By osteotomy, make crossing in processus styloideus radii for Bones and joints
Pressure drop is low, makes the revascularization of subchondral bone matter and increases the stability in joint, this reparation to regression joint, remission is also
It plays an important role.This method protects Bones and joints by the change to shin bone relative to femur obliquity, sets different from total knee
Hand-off art is more suitable for Young Patients, and postoperative period restores, and avoids the limitation of replacement in total knee replacement relevant device 15 years,
Reduce the number and brought pain that patient performs the operation.High Tibial Osteotomy to the old man of mobility reduction be it is a kind of with
The operation of knee prosthesis competition；The subject age of High Tibial Osteotomy selection is relatively light, and mobility is stronger, and with single condyle
Based on Osteoarthritis.It is that one kind makes full use of knee joint health cartilage advantage, is obtaining part just in the cartilage of regression
The operation of reparation, it can mitigate symptom, delay the progress of osteoarthritis, be that one kind can exempt or prolong to 60 years old patient below
The measure of slow joint replacement.
In at this stage, HTO equipment mainly includes in the positioning and guiding of bone saw, and correction filling process by operating procedure to bone
The filling of the positioning device and seam of joint associated components, wherein determination and the guiding excessively following form of multi-pass to bone saw position:
1. drawing auxiliary guide line in corresponding position after cutting epidermis plays steel nail positioning, bone saw is completed to cut the process of saw along guide line, later
Using Interal fixation, artificial bone is clogged at gap；2. the equipment that foreign countries mostly use set type, a set of equipment pass through components
It is corresponding to use, successively complete the process of saw kerf and filling.
But staff thinks in the prior art, still there is following shortcoming, such as traditional manual stroke
Line, the mode of steel nail orientation direction are high to doctor's Capability Requirement, lack auxiliary positioning during cutting saw；For another example complete set of equipments
Although registration and it is at high cost, patient's burden is big.The position of Tibial osteotomy is in the metaphysis of shin bone, and the abundant fracture of blood fortune is cured
The case where conjunction ability is strong, no bone nonunion occurs, and operation essential is that accurately osteotomy is carried out in art, and osteotomy line is located at capitulum fibulae
In upper 1/3 in tibial tubercle lower 1/3 line.The general method for using fluoroscopy during operation, osteotomy is not accurate, and patient and doctor need
X-ray examination is repeatedly carried out, it is big to the damage of patient and doctor.Meanwhile using when osteotomy, being easy to damage under unprotect on rear side of shin bone
Nervus vasculairs.
In conclusion lack at this stage it is a kind of low in cost and during positioning and cutting saw used in accurately HTO operation
Positioning and guiding function accurately Tibial osteotomy guiding protector.
Utility model content
The purpose of this utility model is exactly to solve positioning accuracy in Tibial osteotomy surgical apparatus in the prior art and set
Standby cost contradicts, to the problem of nervus vasculairs protection difference, provides a kind of Tibial osteotomy guiding protector of high position precision,
It is able to the completion HTO operation of low cost.
The concrete scheme of the utility model is:
A kind of Tibial osteotomy guiding protector is designed, is percutaneously installed on the bracket of shin bone top, shank proximal end including being able to,
The bracket includes the locator installed parallel with the proximal ends of tibia plane, and fixed guide pole is slidably mounted on the locator
Interior, the hinged connection of the other end of the fixed guide pole rotates guide rod, and the other end of the rotation guide rod, which is slidably installed, to be cut
The osteotomy of bone support component, the arc of the other end installation isolation shin bone and neurovascular bundle of the osteotomy support component protects shelves
Plate；The osteotomy support component is equipped with the bone saw through-hole consistent with the teeth sizes of bone saw, the osteotomy support component
Inside also sets up the osteotome guide plate of bone saw described in Auxiliary support, and the locator is equipped with consistent with Kirschner wire outer dimension
Location hole, installed between the fixed guide pole and the locator, between the rotation guide rod and the osteotomy support component
Be screwed connection.
In specific implementation, the side that the locator closes on proximal ends of tibia is equipped with the cambered surface for being able to fitting knee joint epidermis.
Cambered surface is corresponding with size at the cambered surface of profile in the capitulum fibulae upper 1/3 on the locator.
In specific implementation, the hinged junction of the fixed guide pole and the rotation guide rod is a point, the locator
Center b point, upper 1/3 in capitulum fibulae at be c point, described a, b, c constitute the right angled triangle for being parallel to proximal ends of tibia plane,
Angle locating for c point is right angle.
In specific implementation, the osteotomy protection plate washer includes scheme mounting rod and arcuation guard bar, the arcuation guard bar
It is arc-shaped or with the arc-shaped of bending.
The utility model has the beneficial effects that:
The generally a set of simple support system of Tibial osteotomy guiding protector, while low in cost, convenient for operation and
Positioning, convenient for the completion of guiding preposition in surgical procedure, bone saw can be after support system be fixed, along the predetermined guidance side of bracket
To carry out cutting,
The design of bracket considers periphery blood vessel nerve tract, has certain supporting role and has accomplished to periphery blood vessel mind
Protection through beam effectively prevent the accidental injury that may cause during sawing bone to nervus vasculairs beam；
Whole equipment controllability is high, is suitble to the skeleton size of most of crowds, easy to adjust in surgical procedure, solid simultaneously
Stable structure after fixed can play reasonable guide effect, the position precision of high-precision control bone saw；
In conclusion the application accurately can be positioned and be oriented to osteotomy direction and position in art, while can
The nervus vasculairs beam on rear side of shin bone is protected, operation safety and accuracy are increased.
