Description

Technical Field

[0001] The invention relates to a neuroendoscopic working sheath, in particular to a multi-purpose neuroendoscopic working sheath. Background Art

[0002] With the development of medical technology, neuroendoscopic technology has been used by more and more medical personnel in the surgical treatment of patients with brain diseases such as hydrocephalus and intracranial arachnoid cysts due to its advantages of less trauma and faster postoperative recovery. When patients undergo brain surgery, the skin at the cross incision of the patient's brain needs to be pulled apart to leave a certain amount of operating and observation space for the operator, so that the neuroendoscopic sheath can enter the brain lesion for surgical operation. Usually, the use of neuroendoscopic sheath can leave a certain amount of operating space for the operator and is widely used. At present, in neuroendoscopic surgery, a large working sheath needs to have devices such as aspirators, electrocoagulation, and flushing tubes, which need to be exchanged and used repeatedly. At the same time, they greatly occupy the space of the working sheath when used, which is relatively cumbersome. Therefore, the existing technology has the problem of cumbersome operation. Summary of the invention

A multi-purpose neuroendoscopic working sheath, comprising: Figure 1-2 As shown, it includes an inner sheath tube 1 and an outer sheath tube 2, four evenly distributed partitions 3 are arranged between the inner sheath tube 1 and the outer sheath tube 2, and cavities 4 are formed between adjacent partitions 3, wherein two symmetrically distributed cavities 4 are provided with lifting mechanisms 5, and the remaining two cavities 4 are respectively provided with a suction tube 6 and a flushing tube 7, and the bottom of the cavity 4 is provided with a suction port 8 and a flushing port 9 respectively connected to the suction tube 6 and the flushing tube 7; the lifting mechanism 5 is connected to an arc-shaped magnetic suction block 10, and the inner side wall of the inner sheath tube 1 is provided with two corresponding magnetic lifting rings 11, one of the magnetic lifting rings 11 is provided with a camera probe 12, and the other magnetic lifting ring 11 is provided with an ultraviolet lamp 13 and an illumination lamp 14.

[0013] The lifting mechanism 5 includes an annular toothed belt 51 fixed in the cavity 4 and distributed vertically, a driving gear shaft 52 and a driven gear shaft 53 are respectively provided at the upper and lower ends of the inner tooth surface of the annular toothed belt 51, the driving gear shaft 52 is connected to a driving motor 54, and a fixing block 55 fixed on the arc-shaped magnetic suction block 10 is also provided on the annular toothed belt 51.

[0014] The inner wall surface of the inner sheath tube 1 is provided with a slide rail 15 , and the back surface of the magnetic lifting ring 11 is provided with a matching slide groove 16 ; the slide rail 15 is provided with limiting recesses 17 on both sides, and the slide groove 16 is provided with protrusions 18 matching with the limiting recesses 17 on both sides.

[0015] The upper ends of the suction pipe and the flushing pipe are connected to the suction device and the flushing device respectively.

[0016] The driven gear shaft and the driving gear shaft refer to shaft bodies having toothed surfaces on their surfaces that mesh with the annular toothed belt.

[0017] The suction port is located below the irrigation port.

[0018] Preferably, a T-shaped cavity distributed in an annular manner is provided above the magnetic lifting ring, a meshing gear is provided in the middle position of the T-shaped cavity, and the meshing gear is connected to a motor; an arc disk is also provided in the T-shaped cavity, a toothed surface is provided on the lower surface of the arc disk, a micro electric cylinder is provided in the middle position above the arc disk, and a camera probe is fixed to the output end of the micro electric cylinder.

[0019] Preferably, the camera probe is fixed to a support rod (the support rod can be fixed to the output end of the micro-electric cylinder), and the camera probe is arranged downward, an outer cover is provided above the support and located above the camera probe, a spherical anti-fouling cover is provided on the inner side of the outer cover and is sleeved on the outer side of the camera probe, sleeves are provided between the two ends of the spherical anti-fouling cover and the support rod, and the sleeves and the support rod are rotatably connected, one of the sleeves is provided with an external gear on its surface, and the external gear is connected with a gear and a driving motor; a wiping cloth is provided on the inner wall of the outer cover, which contacts the surface of the spherical anti-fouling cover to wipe and remove stains on its surface. Wiping cloths are also provided at the rotating inlet and the rotating outlet of the outer cover to further wipe the stains on the surface of the spherical anti-fouling cover, thereby ensuring the shooting clarity of the camera probe, and there is no need to frequently take the probe outside to wipe it. The outer cover and the support rod are detachably connected to facilitate later cleaning.

[0020] When conventional neuroendoscopes are in operation, blood often flows into the working sheath, and the end of the endoscope often drains blood and is contaminated, which requires constant wiping, greatly affecting the operation time and process. However, by using the spherical anti-fouling cover that can be wiped regularly, the lower part of the anti-fouling cover can be kept clean, so that the camera probe can take clear pictures and simplify the operation of medical staff.

[0021] The specific process is: the spherical anti-fouling cover is driven by the driving motor to rotate at a certain period. The dirt or water stains attached to the surface of the anti-fouling spherical cover will be wiped off by the wiping cloth after entering the outer cover, ensuring the cleanliness of the lower part of the anti-fouling cover, thereby making the camera probe take clear pictures and simplifying the operation of medical staff.

[0022] A sealing structure is provided between the bottom of the inner sheath tube and the outer sheath tube.

[0023] The usage process of the present application is as follows: the working sheath of the present application is placed in the designated position, the lifting mechanism starts working, driving the magnetic lifting ring to descend, and then driving the set probe and the lighting lamp to descend to the set position to complete the detection of the enclosed area; when flushing is required, the flusher flushes water from the flushing pipe and the flushing port into the embedded tube enclosure cavity, and when suction is required, the suction device extracts the liquid in the enclosed cavity from the suction port and the suction pipe.

[0024] During the lifting process of the lifting mechanism, the driving motor works, driving the driving gear shaft to rotate, which in turn drives the annular toothed belt to move in an annular shape, and the driven gear shaft at the bottom also rotates accordingly. The movement of the annular toothed belt drives the fixed block to move up and down, and finally drives the arc-shaped magnetic block to move up and down. The arc-shaped magnetic block is magnetically attracted to the magnetic lifting ring, and the up and down movement of the arc-shaped magnetic block drives the magnetic lifting ring to move up and down along the slide rail, and then drives the corresponding camera probe, lighting lamp and ultraviolet lamp to move up and down.
