Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a brain surgery aspirator carrying a light source. Background Art

[0002] The neurosurgical aspirator is a precision medical device designed specifically for neurosurgery. It is used to remove blood, cerebrospinal fluid, tissue fragments, etc. during surgery to keep the surgical field clean, reduce interference with the surgical area, and help surgeons operate more safely and accurately. It includes a suction tube, which is a hollow tube connected to the adjustable negative pressure system of the aspirator body. The suction head can penetrate deep into narrow anatomical spaces, such as the skull, without causing unnecessary damage to surrounding brain cells.

[0003] The inventors of the present application discovered during the intracerebral hematoma removal surgery that when the suction tube contacts the hematoma through the brain stoma, the doctor is limited by the long distance between the hematoma and the stoma and the small size of the stoma, resulting in insufficient light, a small field of vision and blind spots in his field of vision, making it impossible for him to see the edge of the hematoma and the overall picture of the brain tissue. Therefore, he cannot accurately align the end of the suction tube with the hematoma, which can easily cause damage to the surrounding normal brain cells and make it difficult to stop bleeding, which has a serious impact on the surgery. Utility Model Content

[0004] The utility model provides a brain surgery aspirator with a light source to solve the problem that the light source of the brain surgery aspirator interferes with the doctor's field of vision. The specific technical solution is as follows:

[0005] A brain surgery suction device carrying a light source comprises a suction device body, which comprises a suction tube. The brain surgery suction device also comprises: a real-time display component, which comprises an annular mounting seat arranged on the outer peripheral surface of the suction tube, and the annular mounting seat is evenly distributed with at least three point light sources, the illumination areas of the point light sources at least partially overlap, and the illumination direction of the point light sources is toward the end of the suction tube.

[0006] Furthermore, the annular mounting seat is evenly distributed with at least three cameras, which do not interfere with the point light source. The imaging area of the camera and the illumination area of the point light source fall in the same area of the brain tissue. The camera is connected to a display screen, and the camera transmits the acquired image to the display screen for display.

[0007] Preferably, the real-time display component also includes a transparent cover arranged on the outer circumferential surface of the suction tube, which wraps up the point light source, the camera and the annular mounting seat. The transparent cover is made of a transparent material that does not affect the passage of light. The diameter of the transparent cover is larger than the diameter of the suction tube. The end of the transparent cover close to the end of the suction tube transitions to the outer circumferential surface of the suction tube through a curved surface, and the curved surface is tangent to the outer circumferential surface of the suction tube.

[0008] Preferably, the distance between one side of the annular mounting seat close to the end of the suction tube and the end face of the suction tube is A, and A < 40 mm.

[0009] Preferably, the point light source is a cold light source.

[0010] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects:

[0011] By evenly distributing three point light sources on the outer peripheral surface of the suction tube, the present utility model improves the illumination intensity at the end of the suction tube, reduces the shadow of the suction tube, reduces the interference of the shadow to the doctor, enhances the doctor's surgical field of view, enables it to meet the requirements of intracerebral deep hematoma surgery. At the same time, three cameras are evenly distributed on the same horizontal plane as the point light sources, and the image acquisition area of the cameras is the same as the illumination area of the point light sources, which enables the illumination intensity of the images transmitted in real time by the cameras to the display screen to meet the surgical requirements, and reduces the blind area of the doctor's surgical field of view, enabling the doctor to observe the deep hematoma in the patient's brain omnidirectionally through the display screen, improving the possibility of surgical success, and minimizing the damage to the patient's normal tissues during the operation process of the doctor as much as possible.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] In the description of the embodiments of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "inside", "outside", "upper", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0018] As Figures 1 to 2 shown, a neurosurgical aspirator with a light source includes an aspirator body 1. The aspirator body 1 includes an aspiration tube 11 and side holes 12. The aspiration tube 11 is a hollow and slender pipe, whose end contacts the brain tissue, and whose top is connected to a negative pressure control system (conventional technology, not shown in the figure). The negative pressure control system forms an adjustable negative pressure area at the end of the aspiration tube 11, enabling it to suck blood, tissue fragments, etc. The side holes 12 are opened at the top of the aspiration tube 11, which can control the negative pressure of the negative pressure control system, thereby more effectively sucking blood and tissue fragments and avoiding damaging the surrounding normal tissue cells.

[0019] Furthermore, the neurosurgical aspirator further includes: a real-time display component 2. The real-time display component 2 includes an annular mounting seat 21 arranged on the outer peripheral surface of the aspiration tube 11. The annular mounting seat 21 is evenly provided with at least three point light sources 22. At least a part of the illumination areas of the point light sources 22 overlap, and the illumination direction of the point light sources 22 faces the end of the aspiration tube 11.

[0020] Specifically, the inner peripheral surface of the annular mounting seat 21 is tightly connected to the outer peripheral surface of the aspiration tube 11 through shaft-hole fit, and its axis coincides with the axis of the aspiration tube 11. The outer peripheral surface or bottom surface of the annular mounting seat 21 is connected with the point light sources 22 through detachable connection means such as buckles. The point light source 22 is a light source that evenly radiates light in all directions from a mathematical point, and the light rays diverge in a spherical shape.

[0021] Therefore, in this embodiment, the point light sources 22 are arranged on the bottom surface of the annular mounting seat 21, so that its illumination area is only below the annular mounting seat 21, that is, the end of the aspiration tube 11. It can avoid the upward light from affecting the doctor, and it can provide a darker background to improve the illumination effect at the end of the aspiration tube 11. At the same time, each point light source 22 can illuminate a part of the area where the end of the aspiration tube 11 is located, but at the same time, it will produce a shadow of the aspiration tube 11, which will affect the doctor's surgical field of view. Therefore, the three point light sources 22 are evenly arranged around the aspiration tube 11, and the illumination areas generated by each of them can overlap with each other, which can fade the simultaneously generated shadows. The more point light sources 22 there are, the lighter the shadows will be, and the lower the impact on the doctor's surgical field of view will be.

[0022] Further, at least three cameras 23 are evenly distributed on the annular mounting base 21. The cameras 23 do not interfere with the point light source 22, and the imaging area of the cameras 23 and the illumination area of the point light source 22 fall on the same area of the intracranial tissue.

[0023] Specifically, the mounting surfaces of the cameras 23 and the point light source 22 need to be in the same plane to prevent the point light source 22 from illuminating the cameras 23 and causing shadows on the cameras 23 to affect the surgical field of view. Secondly, the shooting area of the cameras 23 is the same as the illumination area of the point light source 22, so that the cameras 23 can clearly shoot the area of the end of the suction tube 11 that needs surgery under the illumination of the point light source 22, improving the utilization rate of the point light source 22 and the cameras 23, reducing the waste of light from the point light source 22 and the situation of insufficient light in the shooting area of the cameras 23, and improving the brightness of the surgical field of view.

[0024] Further, the cameras 23 are connected to a display screen 24, and the cameras 23 transmit the acquired images to the display screen 24 for display.

[0025] Specifically, the three cameras 23 simultaneously transmit video streams to the display screen 24, enabling the display screen 24 to display the content captured by the cameras 23 in real time, allowing the doctor to see the position of the end of the suction tube 11 relative to the intracranial tissue in real time. The cooperation of the point light source 22 and the cameras 23 greatly improves the brightness and range of the doctor's surgical field of view and reduces the blind area of the surgical field of view.

[0026] Further, the real-time display component 2 further includes a transparent cover 25 provided on the outer peripheral surface of the suction tube 11. The transparent cover 25 wraps the point light source 22, the cameras 23, and the annular mounting base 21, and the transparent cover 25 is made of a transparent material that does not affect the passage of light.

[0027] Specifically, the wires of the point light source 22 and the cameras 23 are attached to the outer peripheral surface of the suction tube 11 and connected to the outside, which will hinder the use of the aspirator. At the same time, if the wires are not properly disinfected, it is easy to cause intracranial infection. Therefore, it is necessary to wrap the point light source 22, the cameras 23, and their wires in a closed space to avoid affecting the use of the aspirator. The transparent cover 25 made of transparent material can install the point light source 22, the cameras 23, and the annular mounting base 21 on the outer peripheral surface of the suction tube 11 at the same time without affecting the use effects of the point light source 22 and the cameras 23.

[0028] Further, the diameter of the transparent cover 25 is larger than the diameter of the suction tube 11. One end of the transparent cover 25 close to the end of the suction tube 11 is transitioned with the outer peripheral surface of the suction tube 11 through a curved surface, and the curved surface is tangent to the outer peripheral surface of the suction tube 11.

[0029] Specifically, an inner peripheral surface of the transparent cover 25 and an outer peripheral surface of the suction tube 11 form a cavity for placing a camera 23, a point light source 22, and an annular mounting seat 21. However, the bottom end face of the transparent cover 25 extends beyond the outer peripheral surface of the suction tube 11. During the use of the suction tube 11 by a doctor, the bottom end of the transparent cover 25 will affect the movable end of the suction tube 11 and is prone to damage the surrounding tissues in the brain. Therefore, using a curved surface transition tangent to the outer peripheral surface of the suction tube 11 can make the suction tube 11 have no obvious blockage during movement, improving the use experience of the embodiment of the present utility model.

[0030] Further, a distance between a surface of the annular mounting seat 21 close to the end of the suction tube 11 and an end face of the suction tube 11 is A, and A < 40 mm.

[0031] Specifically, if the small-power point light source 22 is too far from the end of the suction tube 11, it will cause insufficient light intensity at the end of the suction tube 11. However, increasing the power of the point light source 22 will increase the size of the point light source 22, and then increase the size of the transparent cover 25, and then reduce the free movement space of the embodiment of the present utility model in the stoma. Therefore, taking the maximum distance of 40 mm can balance the power and size of the point light source 22, which can not only ensure the lighting effect at the end of the suction tube 11, but also ensure that the top diameter of the suction tube 11 is not too large, restricting the movement space of the suction tube 11.

[0032] Further, the point light source 22 is a cold light source.

[0033] Specifically, a cold light source refers to a light source that generates very little heat during the light-emitting process and hardly contains an infrared spectrum. The characteristics of such a light source are high luminous efficiency and little heat generation. It can ensure that the brain tissue is not burned during the light-emitting process, protect the normal tissue as much as possible, and improve the medical experience of patients.

[0034] Among them, typical cold light sources include LED light sources and optical fibers. In this embodiment, an LED light source is used.

[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
