Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to an intracranial operation positioning device.
Background
Hypertensive cerebral hemorrhage (HICH) is a common neurosurgical severe condition with high mortality. The operation modes of the hypertensive cerebral hemorrhage are numerous, different operation methods are determined according to the bleeding part, bleeding amount, age, bleeding speed, time, basic disease condition, local hospital condition and the like, and common operation modes are as follows:
1. minimally invasive puncture aspiration drainage: for the treatment of HICH by minimally invasive puncture drainage, there are also in China hard channel puncture drainage techniques (e.g. YL-1 puncture needles) and soft channel puncture drainage techniques.
2. Large bone flap craniotomy hematoma removal decompression: is used for treating cerebral hernia with large hemorrhage, and has the advantages of making a large incision on skull, windowing on skull, removing hematoma, and reducing pressure
3. Ossicular craniotomy hematoma removal: is suitable for general hematoma, and has a small window on skull to clear hematoma under direct vision.
4. Along with the progress of technology, the invention of various instruments and related consumables, a method for removing hematoma under minimally invasive direct vision is increasingly focused on various places, such as application of 3D printing technology, neuro-endoscope technology, stereotactic technology, neuro-navigation technology, microscopic extraterrestrial technology and the like, so that more and more treatment means for hypertensive cerebral hemorrhage are provided.
Regardless of the surgical method, however, precise positioning and orientation are critical to the success of the procedure.
The current clinical directional positioning condition of intracranial hematoma operation:
The positioning method comprises (1) positioning the marker under CT guidance (2) positioning according to CT slice line drawing. After the two methods are positioned, the direction of the puncture path is determined according to the space imagination of the CT film, if the puncture point is inserted from the temporal side, the puncture direction is aligned with the (vertical) hematoma sagittal plane, the ear measurement direction of the operator or the puncture direction of one person, and the visual guidance of one person is realized. The direction of the cerebral tissue making device (also called as a transparent hard sheath), the insertion direction of the cerebral compression plate and the direction of removing hematoma are also oriented according to the thought, and the positioning and orientation method is coarse, sometimes causes the operation channel to deviate from the normal direction, and the operator repeatedly adjusts the direction until hematoma is found, so that unnecessary cerebral tissue injury is caused, and great confusion is brought to the operation.
The stereotactic technology and the nerve navigation technology are accurate, but the operation is complicated, the condition of the primary hospital is poor, the equipment is often lacking, the patients with high blood pressure and cerebral hemorrhage are mostly emergency patients, emergency rescue is needed, and only partial patients with relatively small bleeding amount have time to perform the operation.
The 3D printing technology, which combines the stereotactic technology and the navigation technology, is very fashionable at present, and has the defects that the printing of a model takes about 4 hours, is not suitable for emergency operators, is inconvenient to disinfect, and is not suitable for other operation modes except for puncture orientation: such as endoscopic hematoma removal and microscopic hematoma removal. In addition, the directional puncture instrument for craniocerebral hematoma developed in the market cannot truly achieve the purpose of orientation, or has the defects of blocking the operation visual field, inconvenient sterilization and the like, so that the device is difficult to popularize.
Accordingly, there is an urgent need for an intracranial surgical positioning device to solve the above-mentioned problems.
