Problems solved by technology

[0002] At present, in the existing technology, when taking out the bone plate screws in the second operation after the fracture healing of the human body, a large surgical incision is required to expose the full length of the bone plate before taking out the bone plate screws placed in the body, resulting in serious tissue damage and long operation time. Prolonged, increased patient pain and trauma

Abstract

The invention aims to solve the problem that a surgical incision for taking out a bone fracture plate screw is large in the field of medical technology, provides a minimally invasive bone fracture plate screw extraction method, and provides a minimally invasive positioning device for extracting a bone fracture plate screw. The minimally invasive positioning device comprises a bone fracture plate surface tissue peeler, a bone fracture plate screw positioner, and a handle. An application method of the minimally invasive positioning device includes: making a 1-2cm long incision at one end of an original surgical incision, holding the handle, pushing forward to tightly attach the bone fracture plate surface tissue peeler to tissue adhered to the surface of a bone fracture plate, allowing a U-shaped opening at the front end of the tissue peeler to contact with a screw tail cap protruding the surface of the bone fracture plate, allowing a screw positioner positioning hole above the tissue peeler to exactly face to a screw hole, inserting a screw wrench through the screw positioning hole to move the screw from the small incision, sequentially taking out other screws, and extracting the bone fracture plate from the small incision to complete a surgery.

Description

technical field [0001] The invention relates to the technical field of medical equipment. Background technique [0002] At present, in the existing technology, when taking out the bone plate screws in the second operation after the fracture healing of the human body, a large surgical incision is required to expose the full length of the bone plate before taking out the bone plate screws placed in the body, resulting in serious tissue damage and long operation time. Prolonged, increasing the pain and trauma of the patient. Contents of the invention [0003] The purpose of the present invention is to provide a fracture bone plate screw positioning device for taking out fracture bone plate screws with simple operation, high utilization rate and low manufacturing cost in order to avoid large surgical incisions in the prior art and reduce patient trauma. [0004] The invention comprises a bone plate surface tissue stripper, a bone plate screw positioner and a handle. The fron...
