Medical magnetic navigation spotter

Abstract

The invention discloses a medical magnetic navigation spotter, and relates to a medical magnetic detecting, positioning and displaying instrument, in particular to a device suitable for indicating a concrete position of a positioning screw hole of an intramedullary nail on a bone cavity, and detecting, positioning and displaying in other surgical operations, particularly suitable for detecting, positioning and displaying the intramedullary nail of which the far end and near end are provided with oblique interlocking positioning screw holes. The structure of the device comprises a magnetic navigation position detecting controller, a magnetic navigation detector assembly, a detecting lock sleeve assembly, a near end sighting device handle, a magnetic generator, a far end navigation assembly, a far end positioning block, a near end sighting support and a far end connection long rod, wherein the far end positioning block is arranged on the upper part of the near end sighting device handle; the far end connection long rod is arranged on the upper part of the far end positioning block; the far end navigation assembly is arranged on the front part of the far end connection long rod; the magnetic generator is inserted in a far end positioning hole of a far end sighting navigation rod of the far end navigation assembly; and the lower part of the near end sighting device handle is provided with a surgical instrument positioning sleeve.

Description

technical field [0001] The invention relates to a medical magnetic navigation positioning instrument, which relates to a medical magnetic detection, positioning, and display instrument, which is suitable for orthopedic operations to indicate the specific position of the positioning screw hole of the intramedullary nail on the bone cavity and to detect, locate, and display in other surgical operations. The device is especially suitable for the detection, positioning and display of intramedullary nails with oblique locking screw holes or multi-plane interlocking screw holes at the distal and proximal ends. Background technique [0002] At present, the medical system shows that the intramedullary nail positioning hole needs to be positioned under the X-ray machine before drilling the positioning hole in the human bone during orthopedic surgery. The X-rays emitted by the X-ray machine will cause harm to medical staff and patients during the operation. Affecting human health, alt...

Problems solved by technology

Using the patent application number 200410103082.9 for the "Medical Magnetic Positioner" that the applicant of this patent once applied for, manual operations are required to detect the position of the distal positioning hole of the intramedullary nail during surgery, which cannot be done for the above-mentioned two kinds of newly designed intramedullary nails. To detect, locate, and display the specific position of the intramedullary nail positioning hole on the bone cavity, the positioning hole must be drilled in the human bone marrow after positioning under the X-ray machine
