Description

Technical Field

[0001] The present invention relates to the technical field of tumor resection instruments, and in particular to a visual nerve scraper. Background Art

[0002] In recent years, neuroendoscopic technology has been widely used in the resection of skull base tumors. It has the advantages of less trauma, a wide visual range, close observation of the neurovascular structure around the tumor, and mild postoperative reactions. Among the resections of intracranial tumors under neuroendoscopy, it is most widely used in the surgery of pituitary tumors, craniopharyngiomas, and chordomas. Endoscopic surgical approaches often use natural cavities and channels of the human body as surgical channels, so the surgical instruments that can be accommodated in the channels are limited, and the operating space is also affected to a certain extent.

[0003] Currently, the scraper is one of the most frequently used surgical instruments in the process of tumor resection. Its usage methods are mainly: the surgeon holds the endoscope with one hand and operates it, that is, the surgeon holds the neuroendoscope with his left hand and the scraper with his right hand to operate; or the assistant holds the endoscope and the surgeon holds the corresponding surgical instruments with both hands to operate, that is, the assistant holds the endoscope and extends it into the surgical area, and the surgeon performs dual surgical microsurgery; but no matter which operation is performed, it is impossible to achieve complete synchronization between the scraper and the endoscope, that is, when using the scraper, it is not necessarily possible to fully observe the tissue structure of the scraped area in real time, especially when scraping tumors around the cavernous sinus and internal carotid artery. Due to the endoscopic observation angle and the inability of the endoscope to synchronize with the scraper's movement trajectory, it is impossible to observe the mirror image of the surrounding structures when the scraper scrapes the tumor in real time, which increases the risk that the scraper may accidentally injure the cavernous sinus wall or the internal carotid artery wall. Summary of the Invention

[0004] In order to synchronize the scraping ring with the endoscope and improve the safety of the operation, the present application provides a visual nerve scraping ring.

[0005] This application provides a visual nerve scraping circle, which adopts the following technical solutions: A visualized nerve scraper comprises a scraper and a scraper rod fixedly connected to the scraper, wherein one end of the scraper rod away from the scraper is fixedly connected to a scraper handle, an adapter is installed on the scraper rod, an endoscope connecting rod is installed on the adapter, and an endoscope lens is fixedly connected to the end of the endoscope connecting rod close to the scraper.

At this time, the first fixed block and the second fixed block clamp the scraper rod through the rubber pad.

At this time, the sliding rod compresses the second spring through the limit block; then the endoscope connecting rod is manually passed through the fixing ring, and then the sliding rod is released. At this time, the second spring drives the sliding rod to slide through the limit block, and the two sliding rods respectively drive the two arc-shaped clamping blocks to approach each other to clamp and fix the endoscope connecting rod.

[0015] Optionally, the detachable component includes a third fixed block, which is fixedly connected to an end of the connecting rod away from the first fixed block, and a second sleeve is fixedly connected to the side wall of the third fixed block.

[0016] By adopting the above technical solution, when fixing the endoscope connecting rod, first place the endoscope connecting rod in the annular groove, and then rotate the fourth fixing block until it abuts against the third fixing block. At this time, the adjusting member fixes the third fixing block and the fourth fixing block, and the third fixing block and the fourth fixing block fix the endoscope connecting rod.

[0017] Optionally, a third limiting groove is provided on the end surface of the third fixed block close to the fourth fixed block, and a fourth sliding groove is provided on the end surface of the third fixed block away from the second sleeve, and the adjusting member includes a snap ring, which is fixedly connected to the end surface of the fourth fixed block close to the third fixed block, a pressing block is slidably connected in the fourth sliding groove, and a third spring is also fixedly connected to the bottom wall of the fourth sliding groove, and one end of the third spring close to the pressing block is fixedly connected to the pressing block, and a groove is provided on the side wall of the pressing block close to the snap ring, and the side wall of the groove close to the third spring is fixedly connected to the snap block.

[0018] By adopting the above technical solution, when the third fixed block abuts the fourth fixed block, the snap ring passes through the third limiting groove and is inserted into the groove. At this time, the third spring drives the clamping block to be clamped in the ring groove of the snap ring through the pressing block, thereby fixing the third fixed block and the fourth fixed block; when separating the third fixed block from the fourth fixed block, the pressing block is manually pressed, and the pressing block drives the clamping block to slide out of the ring groove of the snap ring, and then the fourth fixed block is manually rotated to separate the third fixed block from the fourth fixed block.

[0022] By adopting the above technical solution, three adapters are installed at the position of the scraper rod close to the scraper, at the connection between the scraper rod and the scraper handle, and on the scraper handle, respectively, so that the relative stability of the scraper and the endoscope lens is higher, thereby achieving an integrated effect of the scraper and the endoscope lens; the distance between the endoscope lens end and the scraper head end is kept consistent, so the object distance is relatively fixed, reducing the probability of unclear image due to changes in the operation area and depth during surgery.

[0023] In summary, this application has the following beneficial technical effects: 1. The adapter setting ensures that the distance between the endoscope lens and the scraping ring remains relatively consistent, and the scraping ring and the endoscope lens are operated synchronously. The focus can be adjusted to near the scraping ring before use, so that the tissue structure of the scraped area can be clearly observed in real time every time the scraping ring is used. Especially when scraping tumors around the cavernous sinus and internal carotid artery, the relationship between the cavernous sinus wall and the internal carotid artery wall and the tumor can be observed in real time at close range. Moreover, the focus and clarity will not change with the depth of the operation site, which greatly reduces the risk of the scraping ring damaging the cavernous sinus wall or the internal carotid artery wall, and improves the safety of the operation. 2. It reduces the difficulty of operation and enables the scraping ring and endoscope to operate in complete synchronization. This means that when using the scraping ring, the tissue structure of the scraped area can be fully observed in real time. This is especially true when scraping tumors around the cavernous sinus and internal carotid artery. Because the endoscope's observation angle is synchronized with the scraping ring's movement trajectory, the mirror image of the surrounding structures can be observed in real time as the scraping ring scrapes the tumor. 3. Titanium alloy is anti-magnetic, which can avoid magnetic field interference and does not affect the use of navigation equipment. In addition, titanium alloy has a certain hardness, which maintains the stability of the connection between the scraping rod and the endoscope connecting rod. 4. By installing three adapters at the position of the scraper rod close to the scraper, at the connection between the scraper rod and the scraper handle, and on the scraper handle, the relative stability of the scraper and the endoscope lens is improved, thereby achieving an integrated effect of the scraper and the endoscope lens; the distance between the endoscope lens end and the scraper head end is kept consistent, so the object distance is relatively fixed, reducing the probability of unclear image due to changes in the operation area and depth during surgery.
