Navigation type minimally invasive bone setting system

Abstract

The invention discloses a navigation type minimally invasive bone setting system which comprises a bone setting plate and a handheld positioning frame, the bone setting plate is provided with a plurality of screw holes, a screw is screwed into each screw hole, the handheld positioning frame is provided with guide holes corresponding to the screws, the handheld positioning frame is provided with a bone setting plate connector, and the bone setting plate connector is connected with the handheld positioning frame. The bone fracture plate connector is of a plate-shaped structure, the thickness and the width of the bone fracture plate connector are the same as those of the bone fracture plate, and the end of the bone fracture plate connector is aligned with the rear end of the bone fracture plate and fixedly connected with the rear end of the bone fracture plate through a detachable connecting mechanism. The bone fracture plate is connected with the handheld positioning frame in a butt joint mode, compared with a traditional lap joint mode, the thickness of a connecting point is obviously reduced, the insertion difficulty of the bone fracture plate is lowered, the incision size of skin and soft tissue can be reduced, larger trauma caused by a bone fracture surgery to a patient is avoided, and therefore the pain of the patient can be relieved, and the patient can be protected from being injured. The patient recovery speed is accelerated.

Description

technical field [0001] The invention relates to a navigation type minimally invasive osteosynthesis system for bone plate implantation surgery, which belongs to the technical field of medical devices. Background technique [0002] Bone plate is a medical device that is often used clinically to fix bones. In order to reduce trauma, relieve pain, and shorten the recovery time of patients, minimally invasive surgery should be used to fix the bone as much as possible. The existing minimally invasive osteosynthesis method is generally to make an incision on the skin and soft tissue at one end of the bone, and then insert a bone plate with a hand-held positioning frame connected to the rear end from the incision, so that it is attached to the bone, and finally through the hand-held positioning frame. Screws are placed in the pilot holes to secure the plate to the bone. The existing minimally invasive bone setting method has the following problems: [0003] 1. The hand-held posi...

AI Technical Summary

Problems solved by technology

This connection method will double the thickness of the connection point, and the incision size has to be increased during the operation, which increases the pain of the patient and prolongs the recovery time of the patient.

Moreover, the connection part and the soft tissue are severely squeezed, and the insertion resistance of the bone plate is large, which increases the difficulty of operation.

[0004] 2. Due to the extrusion of soft tissues such as muscles and ligaments, the bone plate is easily deviated from the preset position after being inserted into the human body. Therefore, multiple people are required to coordinate and control, and many people are occupied during the operation. The operation skills of the participants are high, and a little carelessness Or the lack of tacit cooperation will cause the bone plate to deviate, so that the operation cannot achieve the expected effect

[0005] 3. The axes of the multiple screws used to fix the bone plate are parallel to each other. Each screw is isolated and held without synergy with each other. It does not constitute a structural hold, resulting in insufficient connection. The screws are damaged during the patient’s rehabilitation activities. It is easy to loosen and fall out under axial force, which will bring adverse consequences to the postoperative rehabilitation of patients
