Medical laser position finder

Abstract

A medical laser locator for displaying the actual position of the intramedullary nail hole on bone is composed of light source unit consisting of switching circuit, halogen lamp and light source coupler, detecting and displaying unit consisting of optical fibre, graduated detecting sleeve tube, optical probe and limiter, and laser calibrater consisting of laser device assemblage, laser device regulator assemblage, and check device. Its position detecting method features that the visual light generated by low-power laser is regulated into linear light beam to display the correct position of incision on skin, which is then transmitted via optical fibre to optical probe, and the cold light from the probe can pass through the bone layer to form an obvious light spot on the surface of bone layer to determine the position of locating hole.

Description

technical field [0001] The medical laser positioning instrument and its positioning method of the present invention relate to a medical laser detection, positioning and displaying instrument, which is especially suitable for displaying the specific position of the intramedullary nail positioning hole on the bone in orthopedic operations and detecting in other surgical operations. , locate, and display position. 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 the positioning screw hole can be drilled on 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. , have a strong impact on human health, although there is a far and near end aimer for intramedullary nails, its positioning accuracy is poor, the operation is cumbersome in the operation process, the operation t...

Problems solved by technology

[0002] At present, the medical system shows that the intramedullary nail positioning hole needs to be positioned under the X-ray machine before the positioning screw hole can be drilled on 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. , which seriously affects human health. Although there is a kind of intramedullary nail distal and proximal aimer, its positioning accuracy is poor, the operation is cumbersome during the operation, the operation time is long, and the positioning hole wound is increased during the operation, which increases the pain of the patient.
