Description

Ruler capable of measuring and positioning intracranial focus based on image data

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a ruler that can measure the location to intracranial focus based on image data.

Background

In neurosurgery, the focus in the brain needs to be accurately positioned, and an operation incision of the scalp is designed on the body surface according to the positioning result, so that the incision design is wrong due to inaccurate positioning, tumors cannot be accurately exposed and excised, and the trauma of a patient is seriously increased. Therefore, it is very important to accurately locate the tumor position before operation, and the current advanced method is to accurately locate under the nerve navigation; another approach to more broadly localize lesions is to perform comparisons and measurements on existing image data (CT or MR); the distance between the focus and some mark points on the scalp is measured on the image data, and the projected position of the tumor body surface is located by measuring and marking on the scalp with a ruler according to the distance. The second method of measurement is currently performed using a single ruler for "multiple multi-dimensional" measurements.

The nerve navigation positioning is accurate, but has several problems, firstly, the equipment of nerve navigation is expensive, many hospitals do not have the equipment, but the nerve navigation must carry out MR examination before the operation according to the operation requirement of the nerve navigation, but the reality is that the MR examination specifications of different hospitals are different, so that the examination result of an outer hospital cannot be used for auditing and navigating when the other hospital arrives; especially for some large hospitals, many patients are examined in the outer hospital and then switched to surgery, and can not use the data for neuronavigation, even if the same hospital must be scanned before surgery according to the operating specification of neuronavigation, or can not use the data for neuronavigation. The other practical positioning method is to measure on the image, position and mark on the body surface according to the measurement result, and position the tumor on two dimensions, but the common ruler only can be used for measuring on a single dimension, and a special measuring tool is lacked, so that the measurement is troublesome, and the efficiency is low.

Detailed Description

Referring to fig. 1 to 6, the utility model relates to a ruler based on image data and can carry out measurement location to intracranial focus, it includes two parallel arrangement's first locating rule 1, two second locating rule 2, four pulley 3 that intersect the setting perpendicularly with first locating rule 1, two all be provided with first spout 11, two on the first locating rule 1 all be provided with second spout 21 on the second locating rule 2, first spout 11 sets up along the length direction of first locating rule 1, second spout 21 sets up along the length direction of second locating rule 2, four 3 one end of pulley is installed in first spout 11 of first locating rule 1, the other end of pulley 3 is installed in second spout 21 of second locating rule 2. Wherein in the present embodiment, four of the pulleys 3 each have an hourglass shape.
