Description

Adjustable tibia osteotomy module

Technical Field

The invention relates to the technical field of joint surgery, in particular to an adjustable tibia osteotomy module.

Background

TKA for knee replacement surgery has been a growing history for decades, early knee replacement resulting in low survival of the prosthesis due to improper surgical techniques and imperfect tool design. Early studies focused mainly on how to increase the survival rate of the prosthesis, with mechanical alignment being considered one of the important factors. Studies have shown that incorrect prosthesis placement can affect knee range of motion, stability, and can lead to patient pain, thereby reducing clinical scores and patient satisfaction. Polyethylene gaskets also wear and loose sterility in the long term. Jeffrey et al studies indicate that knee replacement should control the mechanical alignment (MA, mechanicalAlignment) to within + -3 DEG, which is considered a gold standard for knee surgery.

Anatomical alignment (AA, anatomicalAlignment) is reconsidered in the prior art and new alignment approaches are developed: the mechanical alignment (aMA, adjustedMechanicalAlignment), the motion/reverse motion alignment (KA, kinematicAlignment/iKA, inverseKinematicAlignment) and the limited motion alignment (rKA, restrictedKinematicAlignment) are adjusted. These alignment means, such as rKA, iKA, place severe demands on the measurement accuracy. To ensure that the procedure is accurately performed through these concepts, many joint surgeons use computer navigation, acceleration sensors, or robots to complete the procedure. However, the new method has the defects of complicated using steps, long learning period, high cost, high equipment maintenance cost, strong restriction and the like to different degrees, so that more than 97% of cases at present are still positioned by adopting the traditional method.

The traditional extramedullary positioning method uses a set of tibia osteotomy tool, which comprises an osteotomy guide plate and a force line rod, wherein the force line rod is vertically arranged at the bottom of the osteotomy guide plate, and the osteotomy guide plate is a metal guide with grooves. When in use, the force line rod is placed at a position parallel to the mechanical axis of the tibia, so that the swing saw is placed in the groove of the osteotomy guide plate to osteotomy the tibia, and the osteotomy guide plate is perpendicular to the mechanical axis when the plane is seen from the right position. The method is characterized in that whether the force line rod is parallel to the axis of the tibia machine or not is observed by naked eyes, and the judgment accuracy is not high mainly depending on the experience of doctors.

Navigation systems manufactured by using microprocessors in conjunction with electronic components such as acceleration sensors are increasingly used. ABN is not computer navigation in the traditional sense, it can perform angle control of coronal and sagittal positions, but cannot perform rotational positioning in the horizontal direction, and ABN utilizes CAS accuracy and retains the convenience of the traditional tool. The ABN workflow not only approximates conventional methods, but also provides digital feedback and anatomical landmarks to the surgeon reference. The device does not need to calibrate bones in advance, reduces registration time, does not need to drill positioning holes on bones additionally, and reduces wounds. Currently there are mainly the products iAssist and KneeAlign2 (zimmerbimomet, washa, indiana, usa).

The iAssist navigation system is a handheld accelerometer navigation system applied to clinic in recent 7 years, and mainly utilizes 2 acceleration sensors placed vertically to search an osteotomy plane. Theoretically, the product is more suitable for the femur side with a typical center of rotation, while the measurement of the tibia side requires a compensation operation. The measurement principle of the knee alignment 2 femur side is approximately the same, the sensor is fixed on the tibia platform during the measurement of the tibia side, the sensor swings left and right, and the tibia osteotomy plane is determined by fusion operation of acceleration at two points by touching the medial malleolus and the lateral malleolus. The measurement is based on normal anatomy of medial malleolus and lateral malleolus, and the measurement point actually considers the thickness of the skin, is also an appearance measurement, has no distinction from the traditional method, but is combined with the traditional method as a verification step of the traditional method, and has certain help on osteotomy accuracy.

Because of the ease of use, there are many surgeons performing rKA, iKA, and using ABN to perform osteotomy. However, at present, all the devices are disposable products, cannot be reused, and require additional surgical costs. Because of the limitations of the device and the late time of the invention, clinical validation data still diverge, and some students consider it helpful to osteotomy accuracy, but also not to improve the final result.

Therefore, there is a need for a low cost and highly accurate adjustment device.
