Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a neurosurgical device with a flow regulation structure. Background Technology

[0002] Hypertensive intracerebral hemorrhage (HICH) is a disease caused by long-term hypertension leading to pathological changes in intracranial arterioles, including hyaline or fibrous degeneration of the vessel walls, which weakens the elasticity of the vessel walls and causes rupture and bleeding. When a patient experiences emotional excitement, excessive mental or physical activity, or other factors that cause a sharp rise in blood pressure, cerebral hemorrhage can occur. Common sites of hemorrhage in HICH include the basal ganglia, ventricles, thalamus, cerebellum, brainstem, lobes, and subcortex. In the lobes and subcortex, rupture of small aneurysms caused by angioamyloidosis is common. Due to the extremely high mortality and disability rates of HICH, improving the clinical surgical treatment capabilities and levels has become a crucial task. Clinical surgical treatments for HICH include large craniotomy or small craniotomy for hematoma evacuation, burr hole drainage of the hematoma, stereotactic hematoma aspiration, and neuroendoscopic hematoma evacuation.

[0003] With the development of neurosurgery from gross neurosurgery to microsurgical neurosurgery and minimally invasive neurosurgery, neuroendoscopy has become one of the main instruments in minimally invasive neurosurgery.

[0004] Neurosurgery, especially surgery related to cerebral hemorrhage or cerebral hematoma, requires doctors to perform various procedures such as aspiration of blood, irrigation, and electrocoagulation under the assistance of a microscope or neuroendoscopy.

[0005] In existing technologies, the functions of blood suction and flushing are mainly achieved through suction and flushing tubes that extend into the patient's body using self-negative pressure suction and flushing devices. During the blood suction or flushing process, if it is necessary to adjust the flow rate of blood suction or flushing, it can only be adjusted on the device connected to the beginning of the tube, and cannot be directly adjusted on the handheld device body, which is very inconvenient.

[0006] In view of this, there is an urgent need for a neurosurgical device with a flow regulation structure to solve the above problems. Utility Model Content

[0007] In order to help solve the problems existing in the prior art, the present invention provides a neurosurgical device with a flow regulation structure, which adopts the following technical solution, including: a device body, a pipeline and a flow regulation mechanism, wherein the pipeline passes through the device body;

[0008] The flow regulation mechanism includes a limiting channel and a regulating valve. The limiting channel is located inside the device body and is used to limit the pipeline. The regulating valve is movably mounted on the device body, and the movement trajectory of the regulating valve intersects with the limiting channel.

[0009] The flow regulating mechanism includes a first limiting plate and a slide rail. One end of the regulating valve is locked in the slide rail. The first limiting plate is disposed on one side of the regulating valve. The first limiting plate and the regulating valve form a limiting channel. One end of the slide rail extends toward the side closer to the first limiting plate, and the other end extends toward the side farther away from the first limiting plate.

[0010] The regulating valve is disc-shaped, and the first limiting plate is disposed on one circumferential side of the regulating valve.

[0011] The flow regulating mechanism includes a limiter, which has a through hole that passes through it. The through hole is a limiting channel, and the pipeline passes through the limiting channel.

[0012] The limiter has a strip-shaped groove on one side, the regulating valve is slidably mounted on the groove, the groove passes through the through hole, and the device body has a strip-shaped hole whose extension direction is consistent with the extension direction of the groove. One end of the regulating valve extends into the strip-shaped hole.

[0013] The flow regulating mechanism also includes an elastic element, which is used to open or close the regulating valve in the pipeline.

[0014] The limiter is provided with a sliding hole, the inlet end and the outlet end of the through hole are respectively located on both sides of the sliding hole, one end of the regulating valve is inserted into the sliding hole, and the other end of the regulating valve extends out of the device body.

[0015] The regulating valve is U-shaped, with two deformable ends at the opening direction. Both deformable ends are located inside the sliding hole. Several hemispherical protrusions are provided inside the sliding hole. The protrusions are respectively located on the side of the two deformable ends that are far apart from each other. Both sides of the two deformable ends that are far apart from each other are provided with arc-shaped contact surfaces.

[0016] The flow regulating mechanism includes a second limiting plate and a rotating shaft, both of which are mounted on the device body, and one end of the regulating valve is mounted on the rotating shaft;

[0017] When the shaft rotates, the suspension end of the regulating valve approaches or moves away from the second limiting plate, and the second limiting plate and the suspension end of the regulating valve form a limiting channel.

[0018] Both ends of the rotating shaft are equipped with a rotating wrench, and the two rotating wrenches are respectively located on both sides of the device body.

[0019] The above-described structure of this utility model can achieve the following beneficial effects:

[0020] By setting a limiting channel to limit the flow of the pipeline, the pipeline passes through the limiting channel, ensuring that the pipeline follows the movement trajectory of the regulating valve. When the flow rate in the pipeline needs to be adjusted, the regulating valve is driven to move along the trajectory closer to the pipeline until it contacts the pipeline's annular side, compressing the pipeline and reducing the cross-sectional area of ​​the liquid passage at that point, thus reducing the flow rate. When the cross-sectional area of ​​the liquid passage is zero (i.e., the passage is closed), the flow rate in the pipeline reaches its minimum. Conversely, if the flow rate needs to be increased, the regulating valve is driven to move along the trajectory further away from the pipeline, increasing the cross-sectional area of ​​the liquid passage at that point, thus increasing the flow rate. When the regulating valve disengages from the pipeline, the flow rate reaches its maximum. In this way, the flow rate in the pipeline can be conveniently controlled by holding the device itself, greatly improving the convenience of the surgeon's operation and allowing for more timely adjustments to the flow rate.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0030] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0031] Example 1, refer to Figure 1-2 A neurosurgical device with a flow regulation structure includes: a device body 100, a tubing 200 and a flow regulation mechanism. The tubing 200 is inserted into the device body 100. The tubing 200 can deliver fluids (such as Ringer's solution or saline solution) into the patient's body, and can also be used to deliver fluids (such as blood) from the patient's body to the outside of the body.

[0032] The flow regulation mechanism includes a limiting channel and a regulating valve 300. The limiting channel is located inside the device body 100 and is used to limit the pipeline 200. The regulating valve 300 is movably mounted on the device body 100, and the movement trajectory of the regulating valve 300 intersects with the limiting channel.

[0033] Based on the above structure, a limiting channel is set to limit the movement of pipe 200. That is, pipe 200 passes through the limiting channel, thus ensuring that pipe 200 follows the movement trajectory of regulating valve 300. When it is necessary to regulate the flow rate within pipe 200, the regulating valve 300 is driven to move along the trajectory towards the side closer to pipe 200 until the regulating valve 300 contacts the annular side of pipe 200, compressing pipe 200 (which is a flexible hose). This reduces the cross-sectional area of ​​the liquid passage (inner cavity of pipe 200) at that point, thereby reducing the flow rate. When the liquid in pipe 200... When the cross-sectional area of ​​the channel is zero (i.e., the channel is closed), the flow rate of pipe 200 reaches its minimum (pipe 200 is closed); conversely, if it is necessary to increase the flow rate of pipe 200, the regulating valve 300 is driven to move away from pipe 200 along a trajectory, thereby increasing the cross-sectional area of ​​the liquid channel of pipe 200 at that point and thus increasing the flow rate; when the regulating valve 300 is disengaged from pipe 200, the flow rate reaches its maximum; in this way, the flow rate of pipe 200 can be conveniently controlled by holding the device body 100, which greatly facilitates the doctor's operation and allows for more timely adjustment of the flow rate.

[0034] like Figure 1 and Figure 2 As shown, in order to guide and restrict the movement of the regulating valve 300, the flow regulating mechanism includes a first limiting plate 400 and a slide rail 500 (the slide rail 500 is preferably a linear slide rail, but can also be a curved slide rail). One end of the regulating valve 300 is engaged in the slide rail 500. The first limiting plate 400 is disposed on one side of the regulating valve 300, and a limiting channel is formed between the first limiting plate 400 and the regulating valve 300. One end of the slide rail 500 extends towards the side closer to the first limiting plate 400, and the other end extends away from the side of the first limiting plate 400. That is to say, the regulating valve 300 moves along the slide rail... When the two ends of 500 move, they move closer to the first limiting plate 400 and away from the first limiting plate 400, respectively. Since the pipeline 200 passes between the first limiting plate 400 and the regulating valve 300, when the regulating valve 300 is close to the first limiting plate 400, the pipeline 200 is squeezed and the flow rate decreases; conversely, the flow rate increases. Furthermore, the regulating valve 300 is optimally disc-shaped, and the first limiting plate 400 is located on the circumferential side of the regulating valve 300. This prevents the regulating valve 300 from scratching the pipeline 200 when sliding, and the regulating valve 300 can rotate, reducing friction during sliding.

[0035] In addition to Embodiment 1, this utility model also includes Embodiment 2, such as... Figure 3As shown, the difference between Embodiment 2 and the above embodiments is that the flow regulating mechanism includes a limiter 600, which has a through hole 601. The through hole 601 serves as a limiting channel, through which the pipeline 200 passes. A strip-shaped groove 602 is provided on one side of the limiter 600, and the regulating valve 300 is slidably mounted on the groove 602. The groove 602 passes through the through hole 601 (meaning the pipeline 200 passes through the groove 602; ideally, the pipeline 200 passes completely through the groove 602). A strip-shaped hole with the same extension direction as the groove 602 is provided on the device body 100. One end of the regulating valve 300 extends into the strip-shaped hole. Thus, the pipeline 200 passes through the through hole 601 onto the limiter 600, thereby limiting the position of the pipeline 200 and preventing it from detaching from the moving track of the regulating valve 300. When adjusting the flow rate, the regulating valve 300 is driven to slide within the slotted orifice (by flicking the regulating valve 300 with a finger, causing it to slide to one side), thereby moving the regulating valve 300 within the slide groove 602. When the regulating valve 300 approaches the through hole 601, it compresses the pipeline 200, reducing the flow rate; conversely, it increases the flow rate. The flow rate regulating mechanism also includes an elastic element used to reset the regulating valve 300. Thus, if it is necessary to maintain the maximum flow rate for a long time, the elastic force of the elastic element can be set to keep the regulating valve 300 away from the pipeline 200, ensuring that the regulating valve 300 is away from the pipeline 200 when no external force is applied. Conversely, if it is necessary to close the pipeline 200 for a long time, the elastic force of the elastic element can be set to keep the regulating valve 300 close to the pipeline 200, ensuring that the regulating valve 300 closes the pipeline 200 when no external force is applied.

[0036] In addition to Embodiment 2, this utility model also includes Embodiment 3, such as... Figure 4 and Figure 5As shown, the difference between Embodiment 3 and Embodiment 2 is that: the limiter 600 is provided with a sliding hole 603, the inlet end and outlet end of the through hole 601 are respectively located on both sides of the sliding hole 603, one end of the regulating valve 300 is inserted into the sliding hole 603, and one end of the regulating valve 300 extends to the outside of the device body 100; the regulating valve 300 is U-shaped, and the two ends of the opening direction of the regulating valve 300 are deformable ends, both of which are located inside the sliding hole 603 (the pipeline 200 can...). At the end of the deformable end, a through-hole can also be provided on the regulating valve 300 (allowing the pipeline 200 to pass through). Several hemispherical protrusions 604 are provided inside the sliding hole 603. These protrusions 604 are respectively located on the sides of the two deformable ends that are far apart from each other. Each side of the two deformable ends that is far apart from each other is provided with an arc-shaped contact surface 301. Thus, due to the protrusions 604 and the arc-shaped contact surface 301, when the regulating valve 300 moves into the sliding hole 603, and the deformable end contacts the protrusions 604... The two deformed ends move towards each other (the regulating valve 300 deforms), causing the protrusion 604 to exert a thrust on the regulating valve 300 to move outward from the sliding hole. If the pipeline 200 can be located at the end of the deformed end, and no external force is applied to the regulating valve 300, the pipeline 200 is in a normal state (not under compression), maintaining maximum flow. When flow adjustment is required, an external force is applied, causing the regulating valve 300 to slide into the sliding hole 603, causing the end of the deformed end to squeeze the pipeline 200, thus reducing the flow. A through-port is provided on the regulating valve 300 so that the pipeline 200 can pass through. When no external force is applied to the regulating valve 300, the pipeline 200 is in a closed state (in a squeezed state, the through-port and the through hole 601 do not coincide). When it is necessary to open or adjust the flow rate, an external force is applied to make the regulating valve 300 slide into the sliding hole 603, so that the through-port and the through hole 601 gradually coincide, and the flow rate of the pipeline 200 gradually increases until the flow rate of the pipeline 200 reaches its maximum (the through-port and the through hole 601 completely coincide).

[0037] In addition to Embodiment 3, this utility model also includes Embodiment 4, such as... Figure 6As shown, the difference between Embodiment 4 and the above embodiments is that the flow regulating mechanism includes a second limiting plate 700 and a rotating shaft 800 both disposed on the device body 100, and one end of the regulating valve 300 is disposed on the rotating shaft 800; preferably, the rotating shaft 800 is horizontally positioned directly above or below the second limiting plate 700 (the axis of the rotating shaft 800 is perpendicular to the extension direction of the pipeline 200). When the rotating shaft 800 rotates, the suspended end of the regulating valve 300 approaches or moves away from the second limiting plate 700, and the second limiting plate 700... A limiting channel is formed between the suspension end of the regulating valve 300 and the 00. Both ends of the rotating shaft 800 are equipped with rotating wrenches 900, which are respectively located on both sides of the device body 100. Thus, when adjusting the flow rate, the rotating shaft 800 can be easily rotated by rotating the wrenches 900, causing the suspension end of the regulating valve 300 to move closer to or further away from the second limiting plate 700. When the suspension end of the regulating valve 300 moves closer to the second limiting plate 700, the pipeline 200 is compressed, and the flow rate decreases; conversely, the flow rate increases. Furthermore, the presence of rotating wrenches 900 at both ends of the rotating shaft 800 allows for flow rate adjustment from both sides of the device body 100.

[0038] In summary, by setting a limiting channel to limit the flow in pipeline 200, the flow in pipeline 200 is ensured to follow the movement trajectory of the regulating valve 300. When it is necessary to regulate the flow rate in pipeline 200, the regulating valve 300 is driven to move along the trajectory towards the side closer to pipeline 200 until it contacts the annular side of pipeline 200 and compresses the pipeline, reducing the cross-sectional area of ​​the liquid passage at that point, thereby reducing the flow rate. When the cross-sectional area of ​​the liquid passage in pipeline 200 is zero... When the channel is closed, the flow rate of pipe 200 reaches its minimum. Conversely, if it is necessary to increase the flow rate of pipe 200, the regulating valve 300 is driven to move away from pipe 200 along a trajectory, thereby increasing the cross-sectional area of ​​the liquid channel of pipe 200 at that point and thus increasing the flow rate. When the regulating valve 300 is disengaged from pipe 200, the flow rate reaches its maximum. In this way, the flow rate of pipe 200 can be conveniently controlled by holding the device body 100, which greatly facilitates the doctor's operation and allows for more timely adjustment of the flow rate.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
