Description

Technical Field

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

[0002] Neurosurgery is a branch of surgery that, based on surgery as the primary treatment method, applies unique neurosurgical research methods to study the human nervous system, such as the brain, spinal cord, and peripheral nervous system, as well as related accessory structures such as the skull, scalp, cerebral blood vessels, and meninges. It investigates the causes and pathogenesis of diseases such as epilepsy, Parkinson's disease, and neuralgia, and explores new diagnostic, treatment, and preventive technologies.

[0003] Neurosurgical procedures, especially those related to cerebral hemorrhage or cerebral hematoma, require doctors to use endoscopic guides to perform various procedures such as aspiration of blood, irrigation, and electrocoagulation.

[0004] In existing technologies, the function of aspirating blood and fluid during neuroendoscopic surgery is mainly achieved through a suction tube that extends into the patient's body. If it is necessary to enter deeper parts of the brain for suction, the extension depth of the suction tube can only be adjusted by controlling the insertion and removal of the suction device or the guide with endoscopic function. This can easily cause damage to the lesion and is very inconvenient.

[0005] In view of this, there is an urgent need for a guide with a telescopic pipeline structure to solve the above problems. Utility Model Content

[0007] The conduit extends from the guide body into the guide channel;

[0008] A portion of the adjusting element extends to the outside of the guide body;

[0009] The portion of the adjusting element extending to the outside of the guide body allows the tubing to move toward the guide body or guide channel.

[0010] The adjusting component includes a push rod and a connecting component. The guide body has a sliding hole. The two ends of the sliding hole are at different distances from the free end of the guide channel.

[0013] The connector is sleeve-shaped, and the first tube and the second tube are inserted into the connector from both ends respectively.

[0014] The first tube and the second tube are slidably sleeved together, and the connector is fixedly connected to the second tube.

[0015] The first pipe is a corrugated pipe, and the first pipe is connected to the second pipe. The connector is fixedly connected to the second pipe or to one end of the first pipe near the second pipe.

[0016] The guide body has sliding holes on both sides, and there are two push rods. The two push rods are respectively located on both sides of the connector and are slidably located at the two sliding holes.

[0017] The push rod is located at one end outside the guide body, above, below, or to the side of the guide body.

[0018] The push rod has a push button at one end located on the outside of the guide body.

[0032] 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.

[0033] 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.

[0034] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0035] Example 1, refer to Figure 1-2 A guide with a telescopic tubing structure includes: a guide body 100, a guide channel 200, a tubing 300 (the tubing 300 is used to transport fluids, blood clots, etc. from the patient's body to the outside of the body), and an adjustment component. One end of the guide channel 200 is connected to the guide body 100, and the other end is a free end.

[0036] The conduit 300 extends from the guide body 100 into the guide channel 200;

[0037] A portion of the adjusting element extends to the outside of the guide body 100;

[0038] The portion of the adjusting member extending to the outside of the guide body 100 causes the conduit 300 to move toward the guide body 100 or the guide channel 200.

[0039] Based on the above structure, when using the device, hold the guide body 100 and insert the guide channel 200 into the lesion. When it is necessary to extend the tube 300 outward from the guide channel 200, simply use your finger to drive the part of the adjustment mechanism extending to the outside of the guide body 100 to move the tube 300 towards the guide channel 200. When it is necessary to retract the tube 300, use your finger to drive the part of the adjustment mechanism extending to the outside of the guide body 100 to move the tube 300 towards the guide body 100, thus retracting the tube 300 into the guide channel 200. Therefore, it is not necessary to control the entire guide's movement, which is convenient, quick, and unlikely to cause additional damage to the lesion.

[0040] like Figure 1 and Figure 2 As shown, the adjusting component includes a push rod 400 and a connector 500. A sliding hole is provided on the guide body 100, with different distances between the two ends of the sliding hole and the free end of the guide channel 200. The push rod 400 is slidably positioned at the sliding hole, with one end of the push rod 400 located on the outside of the guide body 100. The connector 500 is fixedly connected to the pipeline 300 and is connected to the push rod 400. A push button 401 is provided at the end of the push rod 400 located on the outside of the guide body 100. Thus, by holding the guide body 100, the push button 401 on the push rod 400 can be turned with a finger, causing the push rod 400 to slide within the sliding hole, thereby moving the connector 500 and consequently moving the pipeline 300, completing the adjustment. Furthermore, the end of the push rod 400 located on the outside of the guide body 100 can be positioned above, below, or to the side of the guide body 100. The position of the push rod 400 can be adjusted adaptively during production according to usage requirements and convenience.

[0041] Further optimization involves providing a first slide rail within the guide body 100 to limit the movement of the connector 500, ensuring its horizontal movement and precise control of the pipeline 300.

[0042] like Figure 2 As shown, in order to accommodate the convenience of operation with either the left or right hand, sliding holes can be provided on both sides of the guide body 100, and push rods 400 can be provided on both sides of the connector 500. The two push rods 400 are slidably set at the two sliding holes, so that whether the guide body 100 is held with the left or right hand, the push rods 400 on the corresponding side can be easily moved by the fingers.

[0043] A further optimization is that, in specific implementation, the conduit 300 may include a first conduit 301 and a second conduit 302. The first conduit 301 is connected to the second conduit 302, and the second conduit 302 extends from the guide body 100 into the guide channel 200. The first conduit 301 is disposed within the guide body 100. An adjusting member is used to move the second conduit 302 away from or towards the first conduit 301. The connection method of the first conduit 301, the second conduit 302, and the connector 500 can be: Connection method one, where the connector 500 is sleeve-shaped, and the first conduit 301 and the second conduit 302 are respectively... Connector 500 is inserted into both ends of connector 500 (the first tube 301 can be a flexible tube or a corrugated tube); connection method two, the first tube 301 and the second tube 302 are slidably connected, and connector 500 is fixedly connected to the second tube 302; connection method three, the first tube 301 is a corrugated tube, the first tube 301 is connected to the second tube 302, and connector 500 is fixedly connected to the second tube 302 or to the first tube 301 (the side of the first tube 301 close to the second tube 302) at the end close to the second tube 302; these three connection methods can be selected according to actual usage requirements.

[0044] In addition to Embodiment 1, this utility model also includes Embodiment 2, such as... Figure 3 and Figure 4 As shown, the difference between Embodiment 2 and the above embodiments is that the adjusting component also includes a driving component 600 and a fixing component 700. Part of the driving component 600 is located on the outside of the guide body 100. The driving component 600 is rotatably mounted on the guide body 100, and the fixing component 700 is fixed on the second tube 302. The driving component 600 and the fixing component 700 are in a transmission cooperation. When the driving component 600 rotates, the fixing component 700 moves away from or closer to the first tube 301. In this way, by holding the guide body 100, the driving component 600 can be rotated by finger, causing the fixing component 700 to move linearly, thereby causing the second tube 302 to move, and causing the second tube 302 to extend or retract.

[0045] like Figure 3As shown, the driving component 600 can be a gear, while the fixed component 700 is a rack. The driving component 600 meshes with the fixed component 700, and the extending direction of the rack is consistent with the moving direction of the second tube 302; as shown... Figure 4 As shown, the driving component 600 can also be a threaded rod, in which case the fixing component 700 is a threaded sleeve. The driving component 600 and the fixing component 700 are threadedly engaged, and the axial direction of the threaded sleeve is consistent with the direction of movement of the second tube 302. Thus, by rotating the driving component 600, the fixing component 700 makes linear movement, thereby completing the adjustment of the second tube 302. Furthermore, a second slide rail is provided inside the guide body 100 to limit the movement of the rack or the threaded sleeve, ensuring that the rack or the threaded sleeve moves along the required trajectory (the optimal trajectory is a linear movement towards or away from the guide channel 200). In addition, to facilitate the connection of the second tube 302, the fixing component 700 is also provided with a mounting component 800 for fixing the second tube 302.

[0046] In summary, when using this device, hold the guide body 100 and insert the guide channel 200 into the lesion. When it is necessary to extend the tube 300 outward from the guide channel 200, simply use your finger to drive the part of the adjustment mechanism extending to the outside of the guide body 100 to move the tube 300 towards the guide channel 200. When it is necessary to retract the tube 300, use your finger to drive the part of the adjustment mechanism extending to the outside of the guide body 100 to move the tube 300 towards the guide body 100, thus retracting the tube 300 into the guide channel 200. Therefore, it is not necessary to control the entire movement of the guide, which is convenient, quick, and unlikely to cause additional damage to the lesion.

[0047] 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.
