Description
Technical Field
The invention relates to the field of neurosurgery, in particular to an ultrasonic navigation drainage system for neurosurgery.
Background
With the continuous development of a plurality of technologies such as modern optical technology, electronic technology, space navigation technology and the like, fluorescence microscopy, fluorescence radiography, intraoperative CT and MRI, intraoperative ultrasonic and electromagnetic nerve navigation technology and the like are developed and applied to clinic, so that the precise neurosurgery concepts of accurate positioning, minimum trauma and highest excision rate are deeper into the heart of people. Accurate positioning and intra-operative real-time monitoring are key to determining whether surgery can be successful. However, the requirements of CT, MRI, and fluoroscopic imaging are high in the environment, space, and facilities of the operating room, and the nerve navigation is susceptible to the drift of brain tissue during the operation, and errors occur. In addition, the ultrasonic wave can not cause harm to human body, has no radiation, and can diagnose and treat for many times.
Because of the continuous updating of the instrument, the method is simple and convenient, the report is rapid, the diagnosis accuracy is improved year by year, and the clinic replaces some traditional diagnosis methods. The basic principle is as follows: the ultrasonic wave propagates in human body, and the ultrasonic wave generates physical characteristics such as reflection, refraction, scattering, diffraction, attenuation at interfaces of two different tissues and Doppler frequency shift generated by the relative motion of a sound source and a receiver due to the acoustic characteristic difference of various tissues of the human body. The method is characterized in that different types of ultrasonic diagnostic instruments are applied, various scanning methods are adopted to receive the reflection and scattering signals, various tissues and pathological changes of the tissues are displayed, different reflection rules are combined with pathology and clinical medicine, and the pathological change positions, the properties and the degree of dysfunction are diagnosed by observation, analysis and summarization. In the process of operation, the traditional nerve navigation system which relies on preoperative positioning is difficult to accurately position due to the gradually aggravated brain tissue displacement. Brain tissue displacement is also known as image postbrain tissue distortion or brain tissue deformation. The brain tissue displacement is caused by various reasons, such as brain tissue swelling, cerebrospinal fluid loss, bone flap removal, dura mater opening, brain tissue traction, lesions or brain tissue excision, lesion cyst fluid release, dehydrating agent and anesthetic use, mechanical ventilation, gravity influence and the like.
The prognosis of operation of a patient is related to a plurality of factors, after neurosurgery craniocerebral operation, most of the patient needs to be placed with a drainage tube to drain blood, effusion or cerebrospinal fluid after the operation so as to relieve cerebral edema, the positions of the blood and the effusion can be confirmed through a neurosurgery ultrasonic navigation drainage system, the anchor point of the drainage tube is confirmed, and the postoperative drainage rehabilitation process of the patient is improved.
In order to locate brain tissue displacement and improve patient prognosis in neurosurgery, an ultrasonic nerve navigation system SomoWand is marketed in Norway, which needs to be assisted with other locators to achieve the navigational positioning function of neurosurgery. The siemens's ACUSON sequoia 5.12 color ultrasonic diagnostic apparatus is generally used for imaging of abdomen, chest, cardiovascular and other parts, and is not used for intraoperative and postoperative drainage.
Patent CN112040873a discloses an ultrasound imaging system, which focuses on protecting the control panel, and is not relevant to neurosurgical ultrasound navigation drainage systems. Patent CN108577968a discloses a craniotomy robot based on ultrasonic waves, which does not relate to the aspects of ultrasonic area array probes, ultrasonic imaging depth, ultrasonic working modes, ultrasonic data processing modes, ultrasonic control modes, ultrasonic imaging modes and the like.

In this stage, the ultrasonic signals of the ultrasonic probe 2 are transmitted into the brain through the air, the frequency of the annular phased ultrasonic probe 2 at the bottom of the ultrasonic probe 2 is adjusted to a low-frequency working mode of 0.5MHz as the ultrasonic signals with higher frequency attenuate in the air, and the ultrasonic signals have different reflectivities at the air/hydrocephalus interface, the air/cerebral tissue interface and the air/skull interface due to the existence of acoustic resistance, the positions of hydrocephalus, cerebral tissue and skull are confirmed through ultrasonic echo, and the drainage tube 1 is guided to safely and accurately enter hydrocephalus.

Example 4
The drainage tube 1 of the neurosurgery ultrasonic navigation drainage system is made of silicon rubber through die pressing, the length is 200mm, the diameter is 2mm, the connecting tube 6 is made of silicon rubber through extrusion, the length is 1000mm, and the drainage container 7 is made of polyvinyl chloride through die pressing to form a spring container with the capacity of 50 ml. The ultrasonic probe 2 is made of polypropylene material with low acoustic resistance by injection molding to form an ultrasonic probe 2 shell, electrodes are sequentially arranged on the upper surface and the lower surface of a piezoelectric crystal 8-11, the piezoelectric crystal is arranged on a flexible printed circuit board and then glued into the shell, sound absorbing materials are further arranged in the shell, finally, a lead 5 is connected and then assembled on the drainage tube 1, and the lead 5 is led out.
In the neurosurgery craniocerebral minimally invasive surgery, the preparation stage and the ultrasonic guiding stage are the same as those of the embodiment 1, and in the ultrasonic real-time imaging stage, when pathological tissues are processed, the annular phased ultrasonic probe 2 at the bottom of the ultrasonic probe 2 starts a Doppler ultrasonic mode to scan the brain in real time, after the host computer 3 receives the scanning signal processing, the 3D image of the brain and the vascular position of the pathological tissues are displayed by the display 4, and the brain tissue displacement, the pathological positions in the brain and the distribution of cerebral effusion are confirmed in real time. Compared with the CT/MIR image, the method guides the neurosurgeon to perform the operation, and avoids the operation accidents caused by brain tissue drifting and vascular rupture. The drainage tube 1 is guided to be placed at the bottom of the hydrocephalus so as to ensure sufficient drainage, the hydrocephalus is led out through the drainage tube 1, and the hydrocephalus flows through the connecting tube 6 to be stored in the spring type container.
Comparative example 1
The simple cerebral drainage tube can not accurately guide drainage under the condition of no ultrasonic probe 2, and can not observe the positions of brain tissue, hydrocephalus and pathological tissues in the brain, and the life safety of patients is easily endangered when the operation is performed under the condition of brain displacement.
Comparative example 2
In the neurosurgery ultrasonic navigation drainage system, under the condition that the ultrasonic probe 2 does not have a side convex array ultrasonic probe, an image of pathological tissues with deflection angles cannot be observed, and ultrasonic real-time navigation cannot be performed during operation.
Comparative example 3
In the neurosurgery ultrasonic navigation drainage system, when the impedance of the matching layer material of the ultrasonic probe 2 is not matched with the impedance of cerebral hydrops, the loss of ultrasonic signals is high, and the definition of ultrasonic real-time imaging is reduced.
