Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary appliances, and particularly relates to a nerve endoscope lens flushing device. Background Art

[0002] The nerve endoscope technology is one of the emerging technologies in neurosurgery and has been gradually widely recognized. The nerve endoscope can provide good lighting and imaging angles, reduce the traction of brain tissue, clearly display the anatomical structure of the surgical area without dead angles, have a wider exposure range, be able to observe lesions closely, and discover hidden lesions and responsible blood vessels, greatly reducing surgical trauma, reducing complications, improving the surgical effect, and having good postoperative comfort for patients.

[0003] Currently, during surgery, the nerve endoscope is inserted through the nasal cavity for surgical observation. However, it is often affected by the attachment of substances such as the patient's blood and tissues to the lens and the inner wall of the endoscope, affecting the observation field of view and fineness. In order to restore the clarity of the surgical field of view, or to withdraw the endoscope and instruments from the surgical field, and then re-enter the surgical area after the lens is cleaned clearly. Such operations interrupt the continuity of the surgery, and at the same time, the repeated entry and exit of the endoscope into the surgical area are also likely to damage the surrounding tissues; or other methods are needed to flush during the surgery, which is a complicated process and not conducive to the progress of the surgery, prolonging the surgical time and causing great physical consumption for the surgeon. Summary of the Invention

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0040] Please refer to Figures 1 to 3, A neuroendoscope lens flushing device provided by the present invention includes a neuroendoscope tube main body 10, a flushing outer tube 20, a cleaning mechanism 30 and a suction assembly 40. A lens 11 is provided at the front end of the neuroendoscope tube main body 10. The flushing outer tube 20 is slidably sleeved outside the neuroendoscope tube, and there is a gap between the flushing outer tube 20 and the neuroendoscope tube. The cleaning mechanism 30 is arranged inside the flushing outer tube 20 for flushing the lens 11. The suction assembly 40 is arranged inside the flushing outer tube 20 for sucking out the flushing liquid and blood in the surgical area. Among them, the length of the flushing outer tube 20 is less than the length of the neuroendoscope tube main body 10, so that both ends of the neuroendoscope tube main body 10 extend to the outside of both ends of the flushing outer tube 20, which is convenient for holding the rear end of the neuroendoscope tube main body 10 and sliding it inside the flushing outer tube 20.

[0041] During use, the flushing outer tube 20 is sleeved outside the neuroendoscope tube main body 10 and inserted into the nasal cavity synchronously for surgical observation. At this time, the lens 11 is located outside the front end of the flushing outer tube 20. When there are attachments such as blood on the lens 11, the lens 11 is retracted into the inside of the flushing outer tube 20, and the cleaning mechanism 30 and the suction assembly 40 are started. The cleaning mechanism 30 sprays the flushing liquid to flush the lens 11, and at the same time, it can also brush the substances on the lens 11 that are difficult to be washed away by the flushing liquid; the suction assembly 40 sucks the flushing liquid and blood, and sucks the flushing liquid and blood to the outside. By operating like this to flush the lens 11, the operation can be carried out continuously, conveniently and quickly.

[0042] Please refer to Figures 3 - 7 , a first annular groove 21 is opened on the rear end face of the flushing outer tube 20 along the axial sliding arc plate 31 direction, and a second annular groove 22 is opened on the inner wall of the front end of the flushing outer tube 20. The second annular groove 22 is communicated with the first annular groove 21. The cleaning mechanism 30 includes a flushing part and a brushing part. The front end of the sliding arc plate 31 is slidably inserted into the first sliding groove and slidably connected. One end of the flushing part is inserted into the second annular groove 22 and hinged to the inner wall of the front end of the sliding arc plate 31. The brushing part is arranged at the end of the flushing part away from the hinged end. By sliding the sliding arc plate 31 in the first annular groove 21, the end of the flushing part provided with the brushing part is driven to rotate around the hinged end as the axis, so that the brushing part is aligned with the lens 11, thereby flushing and brushing the lens 11.

[0043] Specifically, a plurality of first flushing holes 35 penetrating in the axial direction are provided on the rear end face of the sliding arc plate 31. The flushing member includes a flushing plate 32 and a plurality of first hoses 33. The flushing plate 32 is hinged to the inner wall of the front end of the sliding arc plate 31 through a hinge member 37. A plurality of through second flushing holes 36 are provided on one side of the end face of the flushing plate 32 close to the hinge member 37. One ends of the plurality of first hoses 33 are respectively communicated with the corresponding first flushing holes 35, and the other ends of the plurality of first hoses 33 are respectively communicated with the corresponding second flushing holes 36. The brushing member is fixedly connected to the end face of the flushing plate 32 away from the hinge member 37. Among them, the brushing member includes multiple rows of bristles 34. The multiple rows of bristles 34 are all fixedly arranged on the end face of the flushing plate 32 away from the hinge member 37, and the multiple rows of bristles 34 are evenly distributed on the end face of the flushing plate 32. The bristles 34 can be used to brush the lens 11, facilitating the removal of attachments on the lens 11 that are difficult to be washed away by the flushing liquid and maintaining the cleanliness of the surgical field of view. The rear end of the first flushing hole 35 is used to input the flushing liquid to provide the flushing liquid for the flushing plate 32. Moreover, on the end face of the flushing plate 32 away from the hinged end, the bristles 34 and the second flushing holes 36 each account for half of the end face area. The flushing liquid can first flush the lens 11, and then the bristles 34 brush the lens 11, so that the attachments on the lens 11 are first flushed and then brushed, making the attachments on the lens 11 easier to be cleaned without stains.

[0044] When there are attachments stuck on the lens 11 and the lens 11 needs to be flushed, the sliding arc plate 31 is pulled backward so that the end of the flushing plate 32 away from the hinged end rotates to align with the lens 11. Then the flushing liquid is conveyed into the first flushing hole 35, and then flows through the suction hose 42 into the second flushing hole 36, and finally sprays from the second flushing hole 36 onto the lens 11 to flush the attachments; when there are still attachments on the lens 11 after flushing, the lens 11 is moved closer to the bristles 34, and the flushing plate 32 is driven to rotate by pulling the sliding arc plate 31 to change the rotation angle of the flushing plate 32, so that the bristles 34 can brush different positions on the lens 11 to clean the lens 11.

[0045] The hinge member 37 includes a hinge shaft 371 and two torsion springs 372. Hinge grooves 373 are provided on opposite sides of the inner wall of the front end of the sliding arc plate 31. Two ends of the hinge shaft 371 are respectively rotatably arranged in the two hinge grooves 373. The hinged end of the flushing plate 32 is fixedly sleeved on the hinge shaft 371. The two torsion springs 372 are respectively sleeved on the two ends of the hinge shaft 371 located in the hinge grooves 373. One end of the torsion spring 372 is fixedly connected to the inner wall of the hinge groove 373, and the other end is fixedly connected to the outer wall of the end of the hinge shaft 371. Among them, the width from the hinged end of the flushing plate 32 to the end provided with the bristles 34 gradually increases. The width change of the flushing plate 32 makes the width of the hinged end of the flushing plate 32 narrow, facilitating the rotation of the flushing plate 32 and avoiding being blocked during rotation.

[0046] Preferably, the cleaning mechanism 30 includes an inclined ring 38. The inclined ring 38 is fixedly connected to the inner wall of one side of the second annular groove 22 through a connecting rod. One side surface of the flushing plate 32 facing the inner wall of the flushing outer tube 20 is fitted and abutted against the outer wall of the inclined ring 38. By pulling the sliding arc plate 31 outwards, with the inclined ring 38 as the fulcrum, the end of the flushing plate 32 provided with the brush 34 rotates in a direction away from the sliding arc plate 31, so that the end of the brush 34 points towards the lens 11 for brushing the lens 11.

[0047] In the initial state, the torsion spring 372 is in a contracted state. Using the restoring elastic force of the torsion spring 372, the flushing plate 32 is closely attached to the outer wall of the inclined ring 38. When the sliding arc plate 31 is pulled backwards, the sliding arc plate 31 drives the hinged end of the flushing plate 32 to move backwards. With the inclined ring 38 as the fulcrum through the flushing plate 32, the end of the flushing plate 32 provided with the brush 34 rotates in a direction away from the sliding arc plate 31. At this time, the torsion spring 372 is further contracted, so that the flushing plate 32 has a pulling force to move back. Moreover, by adjusting the sliding distance of the sliding arc plate 31 in the first annular groove 21, the rotation angle of the end of the flushing plate 32 can be changed, so that the end of the flushing plate 32 is aligned with different places on the lens 11 for flushing and brushing. When the sliding arc plate 31 is pushed forwards, at this time, using the restoring elastic force of the torsion spring 372, the end of the flushing plate 32 moves back, and finally slowly approaches the inner wall of the flushing outer tube 20 to avoid blocking the movement of the lens 11 in the flushing outer tube 20.

[0048] As Figure 2 、 Figure 3 and Figure 8 As shown in

[0049] In this embodiment, the number of the suction assemblies 40 is two, and the two suction assemblies 40 are symmetrically arranged on the flushing outer tube. The suction assembly 40 includes a suction hard tube 41, a suction hose 42 and a suction ball 43. The inside of the suction ball 43 is a hollow structure. A suction groove 44 is formed on the outer wall of the flushing outer tube 20. The suction hard tube 41 is slidably arranged in the suction groove 44, and the length of the suction hard tube 41 is greater than the length of the flushing outer tube 20. The end of the suction hard tube 41 located outside the rear end of the flushing outer tube 20 is used to connect a suction pump. One end of the suction hose 42 is slidably arranged in the suction groove 44 and communicated with the end of the suction hard tube 41. The other end of the suction hose 42 extends to the outside of the front end of the flushing outer tube 20 and is communicated with the inside of the suction ball 43. A plurality of suction holes 45 are formed on the suction ball 43. Among them, the suction hard tube 41 is straight and not easily bent, which is convenient for the sliding of the suction hard tube 41 in the suction groove 44. The suction hose 42 is made of a flexible material and can be bent, so that the suction ball 43 hangs down to a low position, which is convenient for the suction ball 43 to suck the flushing liquid and blood.When it is necessary to aspirate the flushing fluid and blood in the surgical area, start the external aspirator pump to generate negative pressure in the suction tube, place the suction ball 43 in the area to be aspirated, so that the flushing fluid and blood are drawn into the suction ball 43 from the suction holes 45 through negative pressure, and then flow to the outside through the suction hose 42 and the suction hard tube 41; moreover, by sliding the suction hard tube 41 in the suction groove 44, the position and length of the suction ball 43 in the surgical area can be adjusted, facilitating the suction ball 43 to reach the position to be aspirated in the surgical area.

[0050] Preferably, the suction assembly 40 further includes a plurality of limiting arc plates 46, which are arranged at intervals on the outer wall of the outer flushing tube 20, and both sides of the limiting arc plates 46 are fixedly connected to the inner walls of both sides of the suction groove 44. The arrangement of the limiting arc plates 46 facilitates the sliding of the suction hard tube 41 in the suction groove 44, restricts the suction hard tube 41, and prevents the suction hard tube 41 from sliding out of the suction groove 44.

[0051] As Figure 1 shown, in this embodiment, a clamping member 50 is provided on the outside of the outer flushing tube 20 for clamping the main body 10 of the neuroendoscope tube, and the main body 10 of the neuroendoscope tube and the outer flushing tube 20 move synchronously. The clamping member 50 includes a first clamping ring 51 and a second clamping ring 52. The first clamping ring 51 is fixedly sleeved at intervals on the outer side of the rear end of the outer flushing tube 20, the second clamping ring 52 is sleeved on the outer side of the rear end of the main body 10 of the neuroendoscope tube, two symmetrical connecting columns 53 are connected between the first clamping ring 51 and the second clamping ring 52, and two symmetrically arranged clamping grooves 54 are formed on the inner side surface of the second clamping ring 52. A clamping spring 55 is provided in each clamping groove 54. One end of each clamping spring 55 is fixedly connected to the inner bottom wall of the corresponding clamping groove 54, and the other end of each clamping spring 55 extends to the outside of the clamping groove 54 and is fixedly connected to a clamping arc plate 56, and the two clamping arc plates 56 are symmetrically arranged.

[0052] By using opposite forces to push the two clamping arc plates 56 away from each other, the main body 10 of the neuroendoscope tube is sleeved between the two clamping arc plates 56. Using the restoring elastic force of the clamping spring 55, the two clamping arc plates 56 are tightly attached to the outside of the main body 10 of the neuroendoscope tube, so that when the main body 10 of the neuroendoscope tube is moved, the outer flushing tube 20 can move synchronously; moreover, by separating the two clamping arc plates 56, the main body 10 of the neuroendoscope tube can be moved independently.

[0053] Preferably, the clamping member 50 further includes two locking knobs 57. A threaded hole is formed in the inner bottom wall of each clamping groove 54. The end of each locking knob 57 slides through the corresponding threaded hole and the clamping spring 55 and is rotatably connected to the outer side surface of the clamping arc plate 56. An external thread matching the threaded hole is provided on the outer side of the end of each locking knob 57 close to the clamping arc plate 56.

[0054] When it is necessary to separate the two clamping arc plates 56, pull the locking knob 57 outwards until the external thread on the locking rotary knob is screwed into the threaded hole. At this time, rotate the locking knob 57 so that the locking knob 57 is threadedly connected in the threaded hole, thereby fixing the two clamping arc plates 56. At this time, the two clamping arc plates 56 are separated from the outer side surface of the neuroendoscope tube body 10, enabling the neuroendoscope tube body 10 to move independently.

[0055] The working principle of the present invention: In use, first threadedly fix the locking knob 57 on the second clamping ring 52, pass the neuroendoscope tube body 10 through the flushing outer tube 20, loosen the limitation of the locking knob 57, so that the two clamping arc plates 56 are close to the outer side surface of the neuroendoscope tube body 10; then insert the neuroendoscope tube body 10 and the flushing outer tube 20 together into the surgical area of the nasal cavity for observation; when there is blood attached to the lens 11, pull the locking knob 57 outwards, threadedly fix the locking knob 57 on the second clamping ring 52, then retract the lens 11 into the flushing outer tube 20, pull the sliding arc plate 31 outwards, so that the sliding arc plate 31 drives the hinged end of the flushing plate 32 to move, and further makes the flushing plate 32 pivot with the inclined ring 38 as the fulcrum, causing the end of the flushing plate 32 to rotate, so that the end of the flushing plate 32 rotates to align with the direction towards the lens 11, convey the flushing liquid into the first flushing hole 35, so that the flushing liquid flows through the first hose 33 into the second flushing hole 36, and then sprays from the second flushing hole 36 onto the lens 11 to flush the attached substances. At the same time, when there are still attached substances on the lens 11 after flushing, move the lens 11 closer to the brush 34, drive the flushing plate 32 to rotate by pulling the sliding arc plate 31, change the rotation angle of the flushing plate 32, so that the brush 34 can brush different positions on the lens 11 to clean the lens 11; when the lens 11 is flushed clean, continue to observe the surgical area.

[0056] The beneficial effects of the present invention: This neuroendoscope lens flushing device flushes the attached substances on the lens 11 by moving the lens 11 into the flushing outer tube 20, pulling the sliding arc plate 31 outwards, driving the end of the flushing plate 32 to rotate, so that the end of the flushing plate 32 rotates to align with the direction of the lens 11, and making the flushing liquid sprayed from the flushing plate 32 onto the lens 11; at the same time, move the lens 11 closer to the brush 34, and brush the attached substances on the lens 11 that are difficult to clean with the brush 34, so as to clean the lens 11 and restore the clarity of the surgical field of view without pulling the lens 11 out to the outside for cleaning; moreover, the flushing liquid and blood in the surgical area are pumped out through the suction ball 43 and the suction hard tube 41 to avoid affecting the observation of the lens 11; and the clamping member 50 enables the neuroendoscope tube body 10 to move synchronously with the flushing outer tube 20, which is very convenient.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
