This patent focuses onNeurosurgical Tumor Resection Scenario, the core innovation lies in the combination of multi-size extraction rings with a negative-pressure suction cup structure, which addresses the issues of tumor rupture, surgical field contamination, and difficulty in retrieving tumors from challenging locations commonly associated with traditional grasping instruments. This design enables rapid and safe extraction of tumors of varying sizes and is equipped with a sealed sterilization component to ensure clinical hygiene, thereby offering both practicality and clinical safety.
Neurosurgery, as a core clinical specialty dedicated to the diagnosis and treatment of neurological disorders affecting the brain, spinal cord, and other parts of the nervous system, primarily manages critical neurological conditions caused by trauma, intracranial hemorrhage, and compression from brain or spinal tumors, among whichSurgical Treatment of Nervous System Tumorsis a key therapeutic approach in this field.
After the tumor lesion is completely dissected and separated from the surrounding nerves and vascular tissues,Safely and completely remove the tumor tissueIt is a crucial step in ensuring surgical outcomes. Currently, the standard clinical practice still involves direct clamping and lifting using traditional instruments such as surgical forceps and dissectors to achieve tumor resection and removal.
However,This traditional operational model has multiple inherent and unavoidable drawbacks:First, rigid instrument grasping is highly likely to cause tumor tissue rupture and fragmentation, leading to the dissemination of tumor cells into the surgical cavity, resulting in contamination of the operative field and significantly increasing the potential risk of local tumor seeding and spread.
Secondly, traditional grasping instruments have stringent requirements regarding tumor location, orientation, and exposure angle. For tumors in specialized locations with limited operative space, such as the deep intracranial regions, skull base, and intramedullary spinal cord, it is difficult to achieve stable apposition and effective grasping, often resulting in failed attempts and repeated adjustments that prolong surgical time. Furthermore, improper control of force and positioning during grasping may cause inadvertent iatrogenic injury to surrounding fragile nerves, blood vessels, and normal brain tissue, thereby compromising neurological function preservation.
With the increasing adoption of minimally invasive neurosurgery and precision surgery concepts, clinical practice has placed higher demands on the safety, integrity, and controllability of tumor resection.There is an urgent need for a dedicated extraction device that can replace traditional grasping methods, accommodate various tumor morphologies, and offer gentle, safe, and highly efficient operation., addressing the inherent limitations of existing instruments from a technical perspective to meet the core requirements of precision, safety, and minimal invasiveness in neurosurgical procedures.
Addressing the challenges in neurosurgical tumor resectionFragile tissues, susceptibility of the surgical field to contamination, and operational challenges in specialized anatomical locationsTo address a series of clinical pain points, this patent establishes multiple core advantages that distinguish it from traditional devices through novel structural design and innovative working mechanisms, thereby fundamentally resolving the inherent defects of existing technologies.
This device"Negative Pressure Adsorption Extraction"Replacing traditional rigid mechanical grasping, it relies on a built-in vacuum pump to provide stable negative pressure power, and works with selectively openable airflow channels to achieve non-invasive adsorption and fixation of tumor tissue; innovatively adopting“Modular Design of Multi-Size Inner Diameter Extraction Rings”, integrating multiple sets of extraction loops with different specifications on the same extraction tray allows for rapid selection of the appropriate model based on the actual size of the tumor during surgery, significantly enhancing the universal adaptability to tumors of varying volumes and morphologies without the need for frequent instrument changes.
During operation, pressing the selected extraction ring drives the vertical arcuate strip downward, automatically triggering airflow communication between the connecting chamber and the horizontal channel, thereby enabling negative pressure to be precisely applied to the corresponding suction cup, achieving“Single-Point Directional Adsorption, Non-Contact Extraction”, effectively preventing tumor fragmentation, cell scattering, and contamination of the surgical field, thereby significantly reducing the risk of tumor seeding and metastasis.Integrated Sterile Storage Structure with Matching Sealed Box and Sealed Ring Cover, can be directly sealed and stored after sterilization to maintain a continuous sterile state, meeting the clinical needs for immediate access and rapid surgical initiation in the operating room, thereby enhancing hospital infection prevention and control standards as well as surgical turnover efficiency.
Meanwhile,Combined Design of Tilted Suction Cup and Adjustable Component, it can access deep intracranial regions and paraspinal areas within narrow surgical fields, enabling stable suction-based grasping of tumors with poor exposure or in specialized locations, thereby reducing operational difficulty, shortening surgery time, and minimizing collateral damage to surrounding nerves and normal brain tissue.
Overall,This technology integrates broad adaptability, ease of operation, safety and non-invasiveness, sterile controllability, and precision with high efficiency., comprehensively overcoming the limitations of traditional tumor extraction instruments, providing reliable specialized equipment support for precise minimally invasive neurosurgical procedures, and demonstrating outstanding clinical practicality and technological leadership.
