Description

A multifunctional revision surgical tool system

technical field

The invention relates to the technical field of surgical instruments, in particular to a multifunctional revision surgical tool system.

Background technique

Artificial knee arthroplasty has been developed in China for decades. After a large number of primary patients, the number of patients who need revision surgery is also increasing. Therefore, a set of revision surgery tools with complete functions and high precision can be used for revision surgery. Improve the fluency of the operation, save the operation time, improve the success rate and operation experience of the manual repair operation, thereby reducing the operation risk and improving the patient's recovery index.

After the primary prosthesis replacement, due to the patient's unintended trauma or prolonged use, the primary prosthesis may become loose or the bone will be lost again, causing the patient to suffer pain and then lose the ability to walk again. This requires prosthesis revision surgery, that is, the original prosthesis is removed, the bone interface is rebuilt, and the revision prosthesis is accurately installed. There are two important points when performing revision prosthesis surgery: 1. Keep the original bone as much as possible, rebuild the bone interface, and ensure the fit between the revision prosthesis and the articular surface; 2. Accurately locate the relative medullary cavity and the articular surface of the prosthesis position to ensure the precise placement of the prosthesis to restore the joint alignment.

Among them, in knee revision surgery, the reconstruction of the femoral side is more difficult, that is, to ensure that the positioning rod is located in the middle of the medullary canal to reconstruct the force line, and to ensure that the prosthesis fits the bone surface to the greatest extent. This requires surgical tools that can not only achieve precise osteotomy, but also perform precise alignment of force and eccentric positioning of the prosthesis to ensure a successful operation.

However, existing knee revision surgical tools have certain drawbacks:

a. Among the existing revision surgery tools, the osteotomy cannot be directly performed on the condyle trial. The osteotomy tool and the femoral condyle trial are separate. This often requires the doctor to perform osteotomy at the bone interface first, and then perform the condyle trial fit. When the condyle trial position is found to be deviated, it is often impossible to readjust the condyle surface or need to re-cut the osteotomy; this will lead to inaccurate installation of the prosthesis or increase the amount of osteotomy, increasing the risk of surgery.

b. Among the existing surgical tools, the positioning of the medullary cavity and the revision prosthesis is often not carried out on the condyle trial mold, but other positioning tools are used to determine the relative position, and then the doctor adjusts the positioning rod and the condyle trial according to the value determined by the positioning tool. The relative installation position of the mold, due to the step-by-step process, will lead to measurement deviation. When the positioning rod is assembled with the condyle trial mold and placed on the bone interface for reduction, there is often a position deviation, and the intramedullary rod and the condyle need to be removed. Trying out the mold and re-positioning with the positioning tool will prolong the operation time or the force line exceeds the planned range, which increases the risk of surgical failure.

Based on the above shortcomings, the present application provides a multifunctional revision surgical tool system to solve the problems existing in the prior art.

Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

After the primary knee prosthesis replacement, due to the patient's unintended trauma or prolonged use, the primary prosthesis may become loose or the bone will be lost again, causing the patient to suffer pain and lose the ability to walk again. This requires the removal of the original prosthesis, the reconstruction of the bone interface, and the installation of a revision prosthesis. This process is called knee revision surgery. In the existing knee joint revision surgery, the steps on the femoral side are to reconstruct the bone interface first, and then install the condyle trial at the reconstructed bone interface to confirm the relationship between the condyle trial and the femoral force line and the distance between the condyle trial and the femur. Finally, remove the condyle try-out and install the condyle prosthesis.

However, this surgical procedure leads to certain defects: in the prior art, doctors need to perform bone interface osteotomy first, and then perform condyle trial fitting. The installation position of the prosthesis is inaccurate or the amount of osteotomy increases, which increases the risk of surgery. Furthermore, in the prior art, positioning tools are used to determine the relationship between the osteotomy and the force line, and the doctor adjusts the force line rod and the condyle trial according to the determined value. When the force line rod and condyle trial mold are assembled together and placed on the bone interface for reduction, deviations often occur. At this time, the force line rod and condyle trial mold need to be removed and repositioned, which will also increase the risk of surgery. .

Based on this, the present application considers directly confirming the relative position of the force line and the condyle trial on the condyle trial, and directly confirming the osteotomy position on the condyle trial to solve the problems in the prior art.
