A craniocerebral lesion navigation system for primary hospitals

Abstract

The invention relates to a brain focus navigation system for a primary hospital. The navigation system comprises uninjured side body surface positioning meshes, affected side body surface positioningmeshes, a magnetic positioning piece, a laser detector and a suspension directional needle. According to the working principle of the navigation system, one straight line is directed, the straight line passes through the center of the focus, two intersections of the straight line and scalp are an affected side body surface positioning point A and an uninjured side body surface positioning point Brespectively, a surgical incision adopts the affected side body surface positioning point A as the center, during surgery, a laser detector performs multi-angle detection on the portion above the affected side body surface positioning point A, the direction of the laser detector is adjusted constantly, when the direction of the laser detector is consistent with the direction of the suspension directional needle, a laser beam consistent with the straight line of the surgical path is emitted by the laser detector, and therefore the straight line of the surgical path is navigated through the laser beam. The system has the advantages of being simple in structure, low in implementation cost and precise in positioning and achieving wide application prospect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cranial lesion navigation system used in primary hospitals. Background technique [0002] Neuronavigation is the application of the concept and principle of navigation in neurosurgery, assisting surgeons to optimize surgical approach, precise operation range, and reduce surgical trauma. [0003] In today's aging society, cerebral hemorrhage is a common disease of the elderly, and it is also the main cause of death and disability. Because the condition of cerebral hemorrhage changes rapidly, the patient falls into a coma or dying state within a short period of time, so the nearest surgical treatment is often necessary; therefore, cerebral hemorrhage is the most commonly performed operation in the neurosurgery department of primary hospitals. [0004] For deep cerebral hemorrhage, if there is no navigation equipment and only rely on the surgeon's clinical experience, it ...

AI Technical Summary

Problems solved by technology

[0006] (1) Very expensive, only a few tertiary hospitals are equipped with neuronavigation systems, and grassroots hospitals are unable to configure them

[0007] (2) The working principle of the existing neuronavigation system (such as Medtronic's Stealthstation) [registration number: China Food and Drug Administration (Jin) Zi 2013 No. 3543993] is to use thin-slice CT or thin-slice MRI images to establish a The three-dimensional coordinate system digitizes each point, which requires extremely high scanning resolution of CT and MRI, but the resolution of CT and MRI in primary hospitals is not enough, and the images cannot be imported into the neuronavigation system

This data import and coordinate registration process takes about 45-60 minutes, which is extremely unfavorable for emergency surgery of cerebral hemorrhage. 45 minutes is enough to make a patient with cerebral hemorrhage go from light coma to deep coma, brain herniation or death. It is also one of the important reasons why no navigation is routinely performed in cerebral hemorrhage surgery

[0009] (4) The existing neuronavigation system requires the head to be absolutely fixed during the operation to avoid coordinate deviation, so the head frame must be fixed, which is more time-consuming (about 10 minutes more), and many primary hospitals do not have a head frame

[0010] (5) The probe of the existing neuronavigation system is an invasive medical device, which requires high temperature sterilization, and additional time is required for sterilization, which is also very unfavorable for emergency surgery

The technical problem addressed by this patent document is: the navigation equipment in the prior art cannot fully observe the treatment situation during surgical treatment, which often leads to surgical failure, and incomplete surgery will cause secondary damage to the patient, causing The patient cannot fully recover. If things go on like this, it will not only bring pain to the patient, but also cause great inconvenience to the work of the medical staff.

However, there is no report on this navigation system.
