Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an easy-to-operate neurosurgical device. 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] Neurosurgery, especially surgery related to cerebral hemorrhage or cerebral hematoma, requires doctors to perform various procedures such as aspiration of blood and fluid, irrigation, and electrocoagulation under a microscope or with the assistance of a neuroendoscopy.

[0004] In the existing technology, the functions of blood suction and flushing are mainly achieved through suction and flushing tubes that extend from the neurosurgical device into the patient's body. If it is necessary to adjust the flow rate of blood suction or flushing during the process, it can only be adjusted on the device connected to the beginning of the tube, and cannot be directly adjusted on the neurosurgical device, which is very inconvenient.

[0005] In view of this, there is an urgent need for an easy-to-operate neurosurgical device to solve the above problems. Utility Model Content

[0006] In order to help solve the problems existing in the prior art, the present invention provides an easy-to-operate neurosurgical device, which adopts the following technical solution, including: a device body, a tubing and a flow regulating mechanism. The device body includes a handle, a guide part and a guide tube. The guide part is disposed at the top of the handle, the guide tube is disposed at one end of the guide part, and the tubing passes through the guide part and the guide tube.

[0007] The flow regulating mechanism includes a driving component and an extruding component. The handle is provided with a first rotating shaft. The driving component is rotatably disposed at the first rotating shaft. The driving component is provided with a driving part and a mounting part on opposite sides of the first rotating shaft. The driving part is located on the outside of the handle. The extruding component is disposed within the device body.

[0008] The driving component and the extrusion component are driven together. When the driving component rotates, the extrusion component moves closer to or away from the pipeline.

[0009] The drive unit is located at the top of the handle near the guide tube.

[0010] A limit plate is provided on the side of the pipeline away from the extrusion part.

[0011] The guide section is provided with a second rotating shaft parallel to the first rotating shaft. The extruder is rotatably mounted on the second rotating shaft. The extruder is provided with a connecting part and an extrusion part on opposite sides of the second rotating shaft in a circumferential direction. The connecting part is connected to the mounting part, and the extrusion part is located above the connecting part.

[0012] The driving component is provided with a strip-shaped limiting hole, and the connecting part is slidably disposed at the limiting hole.

[0013] The flow regulation mechanism also includes a reset component, which is used to move the extrusion section toward the pipeline side.

[0014] The reset component is an elastic element, with one end connected to the device body and the other end connected to the mounting part.

[0015] A groove is provided on the side of the drive unit away from the handle.

[0016] The guide tube is made of a flexible structure.

[0017] The handle has several anti-slip grooves arranged from bottom to top on the side near the guide tube.

[0018] The above-described structure of this utility model can achieve the following beneficial effects:

[0019] In use, hold the handle with one hand and insert the guide tube to the lesion. When the flow rate needs to be adjusted, rotate the drive unit with your finger. The drive unit rotates in different directions, causing the squeezing element to move closer to or away from the tube. When the squeezing element moves closer to the tube, it squeezes and deforms the tube, gradually reducing the cross-sectional area of ​​the liquid channel inside the tube until the liquid channel is closed. Conversely, when the squeezing element moves away from the tube, it gradually moves away from the tube, allowing the tube to gradually return to its original shape, increasing the cross-sectional area of ​​the liquid channel inside and thus increasing the flow rate. This completes the adjustment of the flow rate. The drive unit extends to the outside of the handle, allowing for one-handed operation by holding the handle with one hand and rotating the drive unit with your finger. This is convenient, quick, and allows for timely flow rate adjustment. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] 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.

[0025] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0026] Reference Figure 1-2 An easy-to-operate neurosurgical device includes: a device body 100, a tubing 200, and a flow regulation mechanism 300. The device body 100 includes a handle 110, a guide 120, and a guide tube 130. The guide 120 is located at the top of the handle 110, and the guide tube 130 is located at one end of the guide 120. The tubing 200 passes through the guide 120 and the guide tube 130. The tubing 200 can be used to deliver fluids (such as Ringer's solution or saline solution) into the patient's body, or to deliver fluids (such as blood) from the patient's body to the outside of the body to remove hematomas.

[0027] The flow regulating mechanism 300 includes a driving member 310 and an extrusion member 320. The handle 110 is provided with a first rotating shaft 111. The driving member 310 is rotatably disposed at the first rotating shaft 111. The driving member 310 is provided with a driving part 311 and a mounting part 312 on opposite sides of the first rotating shaft 111. The driving part 311 is located on the outside of the handle 110. The extrusion member 320 is disposed inside the device body 100.

[0028] The drive component 310 and the extruder 320 are driven together. When the drive component 310 rotates, the extruder 320 moves closer to or further away from the pipeline 200.

[0029] Based on the above structure, when using it, hold the handle 110 with one hand and insert the guide tube 130 into the lesion. When it is necessary to adjust the flow rate of the tube 200, rotate the drive component 310 by flicking it with your finger. The drive component 310 rotates in different directions, causing the extruder 320 to move closer to or away from the tube 200. The extruder 320 moves towards the side closer to the pipe 200 until it squeezes the pipe 200 (the pipe 200 is a flexible hose, or the part in contact with the extruder 320 is a flexible hose), causing the pipe 200 to be deformed. At this time, the cross-sectional area of ​​the liquid channel inside the pipe 200 gradually decreases until the liquid channel is closed. If the extruder 320 moves away from the side away from the pipe 200, it gradually moves away from the pipe 200, causing the pipe 200 to gradually recover. The cross-sectional area of ​​the liquid channel inside gradually increases, increasing the flow rate. In this way, the flow rate of the pipe 200 is adjusted. The drive unit 311 extends to the outside of the handle 110, allowing for one-handed operation by holding the handle 110 with one hand and flicking the drive unit 311 with one finger. This makes the operation easy and the flow rate adjustment timely.

[0030] Further optimizations include, for example Figure 1 As shown, the drive unit 311 is located on the top of the handle 110 near the guide tube 130. Thus, when holding the handle 110, the index finger is in the position of the drive unit 311, which facilitates the adjustment of the flow rate of the tube 200.

[0031] like Figure 1 As shown, in order to restrict the position of the pipeline 200, a limiting plate 400 is provided on the side of the pipeline 200 away from the extruder 320. In this way, the limiting plate 400 and the extruder 320 form a clamping engagement to ensure that the flow rate can be adjusted.

[0032] like Figure 1 and Figure 2As shown, a second rotating shaft 121 parallel to the first rotating shaft 111 is provided inside the guide part 120. The extruder 320 is rotatably mounted on the second rotating shaft 121. The extruder 320 is provided with a connecting part 321 and an extrusion part 322 on opposite sides of the second rotating shaft 121 in the circumferential direction (the axial direction of the first rotating shaft 111 and the second rotating shaft 121 is preferably perpendicular to the extension direction of the pipeline 200, and the pipeline 200 is located on the movement path of the extrusion part 322). The connecting part 321 is connected to the mounting part 312. The extrusion part 322 is located above the connecting part 321. A strip-shaped limiting hole 313 is provided on the drive member 310. The connecting part 321 is slidably mounted at the limiting hole 313. When the extruder 320 rotates, the connecting part 321 slides in the limiting hole 313. Thus, when the drive member 310 rotates, the extruder 320 rotates, causing the extrusion part 322 to move closer to or away from the pipeline 200.

[0033] Furthermore, the flow regulating mechanism 300 also includes a reset assembly (not shown in the drawings). The reset assembly is used to move the squeezing part 322 toward the pipeline 200 side. The reset assembly is an elastic element (such as a spring or sheet). One end of the elastic element is connected to the device body 100, and the other end is connected to the mounting part 312.

[0034] In conjunction with the reset assembly, this application has several implementation methods. One is: the squeezing part 322 is located below the pipe 200, and the elastic force of the elastic member causes the mounting part 312 to move away from the pipe 200. Thus, without applying external force to the driving part 311, the elastic member causes the squeezing part 322 to move towards the pipe 200, keeping the pipe 200 in a closed state. When an external force is applied to the driving part 311, overcoming the elastic force of the elastic member, the mounting part 312 moves towards the pipe 200, causing the squeezing part 322 to move away from the pipe 200, opening the pipe 200, and gradually increasing the flow rate; the second is... The extrusion part 322 is located below the pipe 200, and the elastic force of the elastic member causes the mounting part 312 to move closer to the pipe 200. Thus, without applying external force to the drive part 311, the elastic member causes the extrusion part 322 to move away from the pipe 200, and the pipe 200 is not compressed, maintaining its maximum flow rate. When an external force is applied to the drive part 311, overcoming the elastic force of the elastic member, the mounting part 312 moves away from the pipe 200, causing the extrusion part 322 to move closer to the pipe 200, compressing the pipe 200 and gradually reducing the flow rate. Thirdly, the extrusion part 320 extends from the pipe... One side of the pipe 200 passes through the pipe 200, and the extrusion part 322 is located above the pipe 200. The elastic force of the elastic member causes the mounting part 312 to move away from the pipe 200. Thus, without applying an external force to the drive part 311, the elastic member causes the extrusion part 322 to move away from the pipe 200, and the pipe 200 is not compressed. The pipe 200 is always in the state of maximum flow. When an external force is applied to the drive part 311 to overcome the elastic force of the elastic member, the mounting part 312 moves away from the pipe 200, causing the extrusion part 322 to approach the pipe 200. The pipe 200 is compressed, and the flow gradually decreases. Fourthly: The extrusion member 320 passes through the pipe 200 from one side, the extrusion part 322 is located above the pipe 200, and the elastic force of the elastic member causes the mounting part 312 to move towards the side closer to the pipe 200. Thus, without applying external force to the driving part 311, the elastic member causes the extrusion part 322 to move towards the side closer to the pipe 200, and the pipe 200 is always in a closed state. When an external force is applied to the driving part 311 to overcome the elastic force of the elastic member, the mounting part 312 moves towards the side closer to the pipe 200, causing the extrusion part 322 to move away from the pipe 200, the pipe 200 is opened, and the flow rate gradually increases.

[0035] like Figure 2 As shown, in order to facilitate the finger to operate the drive unit 311, a groove is provided on the side of the drive unit 311 away from the handle 110; and the handle 110 is provided with several anti-slip grooves from bottom to top on the side near the guide tube 130, so as to facilitate one-handed grip.

[0036] A further optimization is that the guide tube 130 is made of a flexible structure, such as a snake bone structure, which allows the guide tube 130 to be bent and the orientation of the end of the guide tube 130 to be adjusted.

[0037] In summary, during use, hold the handle 110 with one hand and insert the guide tube 130 to the lesion. When it is necessary to adjust the flow rate of the tubing 200, rotate the drive component 310 by flicking it with your finger. The drive component 310 rotates in different directions, causing the squeezing component 320 to move closer to or further away from the tubing 200. When the squeezing component 320 moves closer to the tubing 200, it squeezes the tubing 200, deforming it. At this time, the cross-sectional area of ​​the liquid channel inside the tubing 200 gradually decreases until the liquid channel is closed. If the squeezing component 320 moves further away from the tubing 200, it gradually moves away from the tubing 200, and the tubing 200 gradually returns to its original shape. The cross-sectional area of ​​the liquid channel inside gradually increases, increasing the flow rate. In this way, the flow rate of the tubing 200 is adjusted. The drive component 311 extends to the outside of the handle 110, allowing for one-handed operation by flicking the drive component 311 while holding the handle 110 with one hand. This is convenient, quick, and allows for timely flow rate adjustment.

[0038] 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.
