Bone plate with titanium cable and auxiliary positioning device

Abstract

The invention discloses a bone plate with a titanium cable and an auxiliary positioning device. The bone plate comprises an elongated bone plate body, wherein through bone plate screw holes are axially distributed in the bone plate body, and the bone plate body and an auxiliary positioning device are vertically crossed, and the bone plate body is fixed with screws and the auxiliary positioning device is removed after a surgery is finished. In order to overcome the defects of the existing appliance, an innovative bone plate screw hole design is adopted, and the corresponding screws are matched, so that the fixation of the titanium cable and the screws can be completed at the same time, the internal fixation strength is effectively improved, the surgery time is shortened, and the surgery efficiency is improved. The auxiliary positioning device designed for a minimally invasive surgery is matched, so that the surgery can be completed under minimally invasive conditions.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to a surgical instrument input into a human body, in particular to a bone plate with a titanium cable and an auxiliary positioning device clinically suitable for fractures of long tubular bones. Background technique [0002] Fractures of long tubular bones (such as humerus, femur, tibia, etc.) are common types of fractures in orthopedic clinical work. Open reduction and internal fixation are the main treatment methods for such fractures, including intramedullary nails and bone plates. However, these two internal fixation methods cannot provide reliable internal fixation strength, so some operators choose to bind titanium cables with bone plates for fixation. The traditional bone plate does not have a matching titanium cable structure, so the titanium cable may move on the surface of the bone plate after fixation, affecting the fixation effect; on this basis, some device ma...

[0002] Fractures of long tubular bones (such as humerus, femur, tibia, etc.) are common types of fractures in orthopedic clinical work. Open reduction and internal fixation are the main treatment methods for such fractures, including intramedullary nails and bone plates. However, these two internal fixation methods cannot provide reliable internal fixation strength, so some operators choose to bind titanium cables with bone plates for fixation

The traditional bone plate does not have a matching titanium cable structure, so the titanium cable may move on the surface of the bone plate after fixation, affecting the fixation effect; on this basis, some device manufacturers have developed bone plates with a matching titanium cable structure While providing a titanium cable fixation structure, there are also obvious shortcomings. The bone plate needs to be used with a specially designed titanium cable, and in minimally invasive surgery with small incisions, it is very difficult to insert the titanium cable into the reserved hole of the bone plate , In addition, the reserved holes for the independent titanium cable on the bone plate lead to a larger spacing between the nail holes, thereby reducing the number of nail holes; an independently designed titanium cable fixation assembly can also be used with the bone plate, but the use of this fixation assembly requires bone The corresponding nail hole of the plate makes it no longer used for screw fixation, and the titanium cable needs to be locked with a special instrument. After the fixation component is applied, the locking instrument needs to be placed on the side of the bone plate, which makes the locking operation in a small incision. Very difficult in minimally invasive surgery
