Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a quick-insertion type beater for a file body.
Background
Knee joint revision surgery is a complication such as infection, poor prosthesis placement, abrasion, prosthesis loosening, displacement or fracture after primary replacement surgery, and requires replacement by taking out the original prosthesis, which is a more complicated operation than the primary replacement surgery. In recent years, the population of total knee arthroplasty applications has been increasingly younger, and as time passes, the primary replacement prosthesis must undergo aging and wear due to the constraint of service life, so the number of knee revision replacement operations has also increased. Because the primary replacement technique results in the destruction of the normal anatomy of the knee joint and the loss of more bone mass, the surgeon also needs to fix with the corresponding prosthetic patch, intramedullary extension rod when selecting the matched prosthetic size.
At present, the intramedullary extension rod in the total knee revision surgery is connected with the knee prosthesis by screw threads, and when the bone defect of a patient is serious, the intramedullary extension rod is often connected by a Sleeve to ensure the firmness of the implantation of the prosthesis. The Sleeve is implanted with a cavity which is matched with the Sleeve, the Sleeve file is a tool for forming the cavity on the residual bone, and the Sleeve file pulling device is a tool for clamping the Sleeve file and driving the Sleeve file to file the bone.
The prior Sleeve rasping and pulling device on the market has certain defects.
Firstly, because the sizes of bones of all patients are different, the Sleeve of the Sleeve has various specifications, the corresponding Sleeve file also has various specifications, the Sleeve file needs to be gradually increased in specification from small to large to file bones, so frequent disassembly and assembly actions can occur between the file drawing device and the file, rapid disassembly and assembly can not be completed between the traditional Sleeve file drawing device and the Sleeve file, the operation time is prolonged, and the operation risk is increased;
secondly, the existing combination mode of the Sleeve rasping and pulling device and the Sleeve rasp on the market at present mainly comprises an integral type and a split type, the integral type design leads to more specifications of the rasp, the tool manufacturing cost is high, and the structure needs to be replaced gradually. The split type current market is mainly provided with reed type and thread type, the reed type structure needs to be continuously verified to confirm proper elasticity, the excessive elasticity inevitably leads to excessive physical consumption of doctors in the process of frequently changing files, the too small elasticity can lead to loosening in the process of knocking vibration, potential safety hazards exist, the instability of the elasticity leads to the fact that the earlier verification process of the structure is longer, the quality control of instruments is difficult to ensure, and the number of customer complaints is relatively large. The locking process of the threaded locking structure is relatively complicated, and the threaded connection is extremely easy to break in the knocking vibration process.
