Hematoma extraction system, navigation system and hematoma boundary judgment method

Abstract

The invention belongs to the technical field of medical instruments, and particularly discloses a hematoma extraction system, a navigation system and a hematoma boundary judgment method. The hematoma extraction system comprises a navigation unit, an extraction unit and a control unit, wherein the navigation unit navigation unit obtains real patient images and three-dimensional virtual images reconstructed from preoperative images, the navigation unit identifies and tracks a track of the extraction unit and displays the track in a visual three-dimensional graph, the extraction unit is provided with a grabbing claw part, the claw part is provided with a sensing part for distinguishing brain hematoma and brain tissue, the sensing part is connected with the navigation unit, brain hematoma and boundary information of brain tissue are input into the navigation unit and fused with a corrected three-dimensional reconstructed virtual image, the control unit is connected with a control end of the extraction unit, and an opening range and size of the claw part are autonomously or manually controlled according to information of the sensing part. By the adoption of the technical scheme, all the units are matched to complete hematoma removal, and it is guaranteed that brain tissue around hematoma is not damaged.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a hematoma extraction system, a navigation system and a hematoma boundary judging method. Background technique [0002] Cerebral hemorrhage is one of the most important diseases that threaten human life in the world, and it also has the characteristics of high disability rate, high mortality rate and high economic burden. At present, craniotomy is often used clinically to remove hematoma. The disadvantage is that the surgical trauma is large, especially in the treatment of deep hematoma, it is easy to cause damage to important nerve structures in the brain, and the mortality and disability rates are high. Hematoma surgery has high requirements for medical equipment, resulting in high costs and great pain for patients. At the same time, it also has strict requirements for patients' physical conditions. [0003] For this reason, the Chinese patent discloses a series of kits ...

At present, craniotomy is often used clinically to remove hematoma. The disadvantage is that the surgical trauma is large, especially in the treatment of deep hematoma, it is easy to cause damage to important nerve structures in the brain, and the mortality and disability rates are high. Hematoma surgery has high requirements for medical equipment, resulting in high costs and great pain for patients. At the same time, it also has strict requirements for patients' physical conditions

[0004]However, the above structure has the following problems: the operating space of the endoscope is small, the field of view is limited, the kit cannot be accurately deployed inside the hematoma, the hematoma cannot be completely captured, and the claws are stretching Sometimes it will damage the brain tissue around the blood clot, causing re-bleeding
