Description

Technical Field

[0001] This utility model generally relates to the field of medical device technology, and more specifically, to a multifunctional neurosurgical endoscope. Background Technology

[0002] Neurosurgical endoscopy is a prominent representative of the concept of minimally invasive neurosurgery. Using neuroendoscopic techniques to treat nervous system diseases has the advantages of minimal trauma, high safety, rapid recovery, and low cost.

[0003] Neuroendoscopic surgery is divided into two main categories based on the endoscopic working environment and operational characteristics: Aqueous environment neuroendoscopic surgery, which uses cerebrospinal fluid as the light source and employs a sheath endoscope and its associated miniature endoscopic instruments. The instruments reach the surgical area coaxially and parallel to the endoscope through the intrathecal channel. The surgical area is within the ventricle or the cavity of a cerebrospinal fluid-like cyst. Typical procedures include endoscopic third ventriculostomy for hydrocephalus and endoscopic cyst-cistern patency for intracranial arachnoid cysts. Air environment neuroendoscopic surgery, which uses air as the light source and employs an observation endoscope and microsurgical instruments or specialized endoscopic instruments. The instruments are positioned outside the endoscope at an angle to reach the surgical area. The surgical area is on the brain surface or skull base. Typical procedures include endoscopic transsphenoidal pituitary tumor resection and endoscopic intracerebral hematoma evacuation.

[0004] Existing neurosurgical endoscopes have limited functionality and require the use of medical devices such as irrigation devices and electrodes, which not only occupy a large operating space but are also very inconvenient to operate. Utility Model Content

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0029] like Figure 1 and Figure 2 As shown in the embodiment, a multifunctional neurosurgical endoscope includes: a neuroendoscopy assembly, a coagulation assembly, an irrigation and aspiration assembly, and a handle 1; the working ends of the neuroendoscopy assembly, the coagulation assembly, and the irrigation and aspiration assembly are all integrated at one end of the handle 1, and the coagulation assembly can extend or retract relative to the handle 1; the other end of the handle 1 is provided with an adjustable switch 2 and a telescopic button 3, the adjustable switch 2 is used to control the on / off state of the irrigation and aspiration assembly, and the telescopic button 3 is used to control the extension or retraction of the coagulation assembly. This application acquires images using a neuroendoscopic component. When a ruptured blood vessel is observed, the coagulation component extends via the telescopic button 3 and contacts the ruptured blood vessel to close it, achieving coagulation. When the tissue is unclear, the irrigation and suction component is used for intraoperative care. When a hematoma is observed, only the suction channel 10 of the irrigation and suction component needs to be opened to suction out the blood clot. The entire surgery is a minimally invasive procedure performed under direct visualization with the neuroendoscopic component, resulting in more precise coagulation, more thorough hematoma removal, and less surgical damage. It overcomes bleeding caused by blind operation, allows for the removal of hematomas over a wider area, integrates coagulation function, achieves multifunctionality, occupies little operating space, is easy to operate, effectively reduces surgical time, and allows patients to recover faster.

[0030] like Figure 2 As shown, in some embodiments of this utility model, the neuroendoscopy assembly includes a camera module 4, LED beads 5, a wire 6, and a display screen. The camera module 4 and LED beads 5 are integrated into one end of the handle 1. One end of the wire 6 passes through the handle 1 and is electrically connected to the camera module 4 and LED beads 5, while the other end of the wire 6 is electrically connected to an external display screen. The camera module 4 is used to acquire image information and transmit it to the external display screen via the wire 6 for display, facilitating observation of the internal condition by medical personnel. The LED beads 5 can be symmetrically arranged relative to the camera module 4, providing good illumination for the camera module 4.

[0031] like Figure 1As shown, in some embodiments of this utility model, the coagulation assembly includes an electrode 7 and a power supply line 8. One end of the electrode 7 can extend or retract relative to the handle 1, and the other end of the electrode 7 is connected to a power source via the power supply line 8. When not in use, one end of the electrode 7 can be retracted into the handle 1 to protect the electrode 7 and prevent movement interference that could affect other operations. When in use, one end of the electrode 7 is extended and brought into contact with the damaged blood vessel to close the vessel and achieve coagulation.

[0032] like Figure 1 As shown, in some embodiments of this utility model, the telescopic button 3 is connected to the electrode 7, and the handle 1 is provided with a movable groove for the electrode to pass through. The telescopic button 3 extends out of the movable groove and moves relative to the movable groove to drive the electrode 7 to extend or retract relative to the handle 1. Pushing the telescopic button 3 forward causes one end of the electrode 7 to extend out of the handle 1; pulling the telescopic button 3 back causes one end of the electrode 7 to retract into the handle 1. The operation is simple and convenient.

[0033] like Figure 2 As shown, in some embodiments of this utility model, the electrode 7 adopts a bipolar electrode head. A bipolar electrode (BPE) is a conductor immersed in the electrolyte between the anode and cathode that is not connected to an external power source. The side closer to the anode of the driving electrode 7 acts as the cathode and undergoes a reduction reaction, while the side closer to the cathode of the driving electrode 7 acts as the anode and undergoes an oxidation reaction, thus simultaneously serving as both an anode and a cathode.

[0034] like Figure 1 As shown, in some embodiments of this utility model, the rinsing and suction assembly includes a rinsing channel 9 and a suction channel 10. One end of the rinsing channel 9 and the suction channel 10 is integrated into one end of the handle 1, and the other end of the rinsing channel 9 and the suction channel 10 extends out of the other end of the handle 1 and is respectively connected to the rinsing device and the suction device. The rinsing device and the suction device are externally mounted and their power can be adjusted; they are not shown in the accompanying drawings.

[0035] like Figures 3-5As shown, in some embodiments of this utility model, the adjustable switch 2 includes a switch housing 11, a movable block 12, and a spring 13. The switch housing 11 is disposed on the passageway between the flushing channel 9 and the suction channel 10. The movable block 12 is movably connected to the switch housing 11. The movable block 12 is provided with a first through hole 14 corresponding to the suction channel 10 and a second through hole 15 corresponding to the flushing channel 9. The spring 13 is disposed between the movable block 12 and the switch housing 11 and acts on the movable block 12 in the direction of movement. The adjustable switch 2 mainly realizes the opening and closing of the flushing channel 9 and the suction channel 10, which is convenient for medical staff to adjust during surgery and has the advantage of high efficiency. The movable block 12 moves laterally relative to the switch housing 11. Under the action of the spring 13, the movable block 12 moves away from the spring 13. By pressing the movable block 12, the movable block 12 moves closer to the spring 13, thereby changing the positional relationship between the first through hole 14 and the second through hole 15 and the suction channel 10 and the flushing channel 9, so as to realize the on / off control of the suction channel 10 and the flushing channel 9.

[0036] In some embodiments of this utility model, the width of the first through hole 14 is greater than the width of the second through hole 15. For example... Figure 3 As shown, the adjustable switch 2 is in the initial state, the movable block 12 is at its extreme position away from the spring 13, the first through hole 14 is misaligned with the suction channel 10, and the second through hole 15 is misaligned with the flushing channel 9; at this time, both the suction channel 10 and the flushing channel 9 are in the off state, and at the working end, the flushing and suction assembly is in a non-working state.

[0037] like Figure 4 As shown, the adjustable switch 2 is in the first working condition. By slightly pressing the movable block 12, the movable block 12 is moved to the middle position, the first through hole 14 is connected to the suction channel 10, and the second through hole 15 is connected to the rinsing channel 9. At this time, both the suction channel 10 and the rinsing channel 9 are connected. At the working end, the rinsing and suction assembly is in full working condition, that is, the rinsing channel 9 is filled with rinsing fluid, and the suction channel 10 discharges waste fluid. The rinsing and suction assembly is used for intraoperative care when the tissue is unclear.

[0038] like Figure 5 As shown, the adjustable switch 2 is in the second working condition. By pressing the movable block 12 with gravity, the movable block 12 is at its extreme position near the end of the spring 13. The first through hole 14 is connected to the suction channel 10, and the second through hole 15 is offset from the flushing channel 9. At this time, only the suction channel 10 is in the connected state, while the flushing channel 9 is in the disconnected state. After the hematoma is formed, only the suction channel 10 of the flushing and suction assembly is opened to suction out the blood clot, achieving efficient suction.
