Description
Technical field
The present invention relates to technical field of medical instruments, specifically, be a kind of noinvasive headstock for Use of Neuronavigation.
Background technology
Neuronavigation system one provides preoperative formulation operation plan, art instructs the placement technology of operation technique, it is by neuroimaging diagnostic techniques, stereotactic surgery and microsurgery are combined by high-performance computer, fictionalize the three dimensional structure of patient's intracranial, between virtual digitized image and actual nervous system anatomical structure, GPS positioning principle is used to set up dynamic contact, understand the relation at operation technique position and surrounding important structures in real time, reach to obtain the purpose of removal of lesions with minimum surgical injury, and function of nervous system can be retained to greatest extent.Neuronavigation system is as a kind of medical science auxiliary positioning equipment, it is possible to provides information in real-time art for doctor, effectively compensate for traditional neural deficiency surgically, improve surgical quality.At present, in neurosurgery, patients head is fixed (such as the DORO tri-ailhead frame that Germany produces) by conventional invasive three ailhead frame, it is by piercing through scalp by head nail, it is embedded on skull immobilized patients head, such headstock good stability, it is possible to meet good head position and fix, but it has a disadvantage in that (1) wound is big, the headstock is when fixing head, and three sharp-pointed head nails need to wear out scalp, the through lamina externa cranii of muscle, it is easy to hurt blood vessel and the nerve of scalp and muscle；(2) sequela is obvious, owing to head suffers three nail wounds, causes the hemorrhage and postoperative long headache of point of puncture, scalp pain or numbness of scalp, this pain and numbness of scalp usually protracted course of disease, makes doctors and patients quite worried；(3) affect attractive in appearance, when forehead is fixed, head nail need beat at frons, not having hair to cover, often a hole for nailing is at the doozy position of forehead herein, and sometimes due to accidentally, even head nail slides and causes bigger wound, it is necessary to sews up, largely effects on attractive in appearance；(4) headstock installation procedure is complicated, all needs to check equipment performance before and after using every time, once find that head nail by rust of a specified duration or occurs that the abnormal conditions such as barb just can not re-use, installation process at least needs two people to coordinate, and for preventing pain, patient needs general anesthesia more.Additionally, three ailhead framves are in use it is also possible to cause the generation of some complication, as hemorrhage in skull nail, wound infection；After operation terminates, while laying down headstock grasping system, air can penetrate into vein blood vessel from skull nail rapidly, to cause the danger that air embolism occurs；For some patient, skull itself is relatively thin or the infant patient of incomplete development, the skull also having itself to cause because there is pathological changes in brainpan becomes the relatively thin patient of ratio, it is possible that some symptoms during headstock grasping system in carrying out craniocerebral operations, the danger such as such as meningitis, epidural hematoma, cerebrospinal leak, severe patient results even in cerebral cortex injury.Fig. 1 is the fixing head situations of existing three ailhead framves.
Chinese patent 2015205394866 discloses a kind of for the headstock in cranial nerve MVD, and including fixing brachium pontis, mobile brachium pontis, the described headstock also includes the fixing cushion of occipitalia, the fixing cushion of forehead, temples support head rest；It is curved that described occipitalia fixes cushion, forehead fixes cushion；Described temples support head rest is rounded, and this headstock has non-invasive, and to scalp, muscle and skull not damaged, fixed effect is definite, and stability is strong, it is possible to meet operation requirement.Chinese patent 201520558897X discloses a kind of neurosurgery Multifunctional head frame, including head rest body, head rest balladeur train and head rest connect axle, head rest body and head rest connect axle and are dynamically connected with head rest sledge slide, nail frame includes the first nail frame and the second nail frame, the rack structure of the second nail frame and the groove slip clamping of described first nail frame, fixing connection dish respectively with the first nail frame, head rest connects axle and bracing frame connector is rotationally connected, support frame as described above connector and bottom support frame are connected by universal drive shaft, this headstock is avoided using head nail, may insure that operative site is centrally located, more practical and convenience in operation.And about the noinvasive headstock that the present invention is used for Use of Neuronavigation, yet there are no report.
