Description

A neurosurgical device channel structure Technical Field

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

[0002] Neurosurgery, especially neurosurgery related to cerebral hemorrhage or cerebral hematoma, requires doctors to perform the surgery under a microscope or through a neuroendoscopy. The surgery is performed with the assistance of neuroendoscopic imaging, using instruments such as suction devices, irrigators, and bipolar electrocoagulation devices to perform various operations such as aspiration of blood and fluid, irrigation, and electrocoagulation.

[0003] When using a neuroendoscope, the doctor inserts the endoscope into the patient's body to obtain real-time images of the lesion, and then treats the lesion using instruments such as suction devices, irrigation devices, and bipolar electrocoagulation.

[0004] Chinese patent publication number "CN201743765U" discloses a bipolar electrocoagulation suction tube for neuroendoscopic surgery. The bipolar electrocoagulation and suction tube are designed as separate units, which better meets practical needs. It includes a suction tube, bipolar electrocoagulation, electrocoagulation leads, and the suction tube is divided into a dual-channel structure with a forked bipolar electrocoagulation insertion channel. The rear end of the suction tube channel is bent and has an operating handle with a side hole for controlling suction. The suction port of the suction tube and the forked bipolar electrocoagulation tip are adjacent to each other to form a wedge-shaped structure, allowing the surgeon to operate independently during surgery. However, its dual-channel structure is an inflexible rigid metal structure. If the orientation of the suction tube or other tubes needs to be adjusted according to the condition of the lesion during surgery, the entire device must be swung to adjust the orientation, which can easily cause secondary damage to the lesion and is very inconvenient.

[0005] In view of this, there is an urgent need for a neurosurgical device channel structure to solve the above problems. Summary of the Invention

[0006] To help solve the problems existing in the prior art, the present invention provides a neurosurgical device channel structure, which adopts the following technical solution, including: a channel tube, an adjusting rope and a driving component. The channel tube is provided with a guide channel, and a deformation groove is opened on the circumferential side of the channel tube. The deformation groove extends spirally around the circumferential side of the channel tube.

[0007] The channel tube has a free end and an installation end at both ends of the deformation groove, and the installation end is fixed to the device body;

[0008] The two ends of the adjusting rope are a fixed end and a driving end, respectively, and the fixed end is connected to the free end of the channel tube;

[0009] The drive element is used to move the drive end of the adjusting rope toward the side closer to or further away from the free end of the channel tube.

[0010] The channel tube ring side is provided with several limiting modules distributed from the free end to the installation end. Each limiting module consists of two limiting holes, and the adjusting rope passes through the channel tube and out of the channel tube through the two limiting holes respectively.

[0011] The regulating rope is provided in several parts, and the several regulating ropes are respectively arranged in different circumferential directions of the channel tube.

[0012] The driving component includes several sliders, which are slidably disposed on the device body. The sliding direction of the sliders is consistent with the extension direction of the channel tube. The free ends of several adjusting ropes are respectively connected to several sliders.

[0013] Four adjusting ropes are provided, and the four adjusting ropes are evenly distributed in a circle around the channel tube.

[0014] The driving component includes a first turntable and a second turntable, both of which are rotatably mounted on the device body. The rotation axes of the first turntable and the second turntable are different from the extension direction of the channel tube.

[0015] The driving ends of the two adjusting ropes are respectively connected to the first turntable at different circumferential angles;

[0016] The drive ends of the other two adjustment ropes are connected to the second turntable at different circumferential angles.

[0017] The rotation axis of the first turntable is set horizontally, and the rotation axis of the second turntable is set vertically.

[0018] Both the first and second turntables are coaxially equipped with rudders, which are located on the outside of the device body.

[0019] The free end of the channel tube is provided with an end cap, and the end cap is provided with several mounting holes.

[0020] The end cap has a chamfered edge on its circumferential side.

[0021] The above-described structure of this utility model can achieve the following beneficial effects:

[0022] In use, the free end of the channel tube is inserted into the patient's body. To adjust the orientation of the tube, the driving end of the adjusting rope is moved away from the free end of the channel tube by the driving component, causing the free end of the channel tube to rotate towards the side where the adjusting rope is being pulled, thus adjusting the orientation of the tube. When resetting is required, the driving end of the adjusting rope is moved closer to the free end of the channel tube by the driving component, and the channel tube returns to its original position. In this way, the orientation of the channel tube can be easily adjusted without the need for the entire adjustment device body, reducing harm to the patient. Attached Figure Description

[0029] 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.

[0030] 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.

[0031] The present invention will be further described in detail below with reference to Figures 1-5.

[0032] Example 1, referring to Figures 1-3, a neurosurgical device channel structure includes: a channel tube 100, an adjustment rope (not shown in the figure, which can be a steel wire rope, etc.) and a driving component. A guide channel is provided inside the channel tube 100, and a deformation groove 101 is opened on the circumferential side of the channel tube 100. The deformation groove 101 extends spirally around the circumferential side of the channel tube 100.

[0033] The two ends of the channel tube 100 at the deformation groove 101 are a free end and an installation end, respectively, and the installation end is fixed to the device body;

[0034] The two ends of the adjusting rope are a fixed end and a driving end, respectively, and the fixed end is connected to the free end of the channel tube 100;

[0035] The drive element is used to move the drive end of the adjusting rope toward the side closer to or further away from the free end of the channel tube 100.

[0036] Based on the above structure, during installation, the relevant tubing (suction tube, flushing tube, endoscope wiring, etc.) is threaded through the channel tube 100; during use, the free end of the channel tube 100 is inserted into the patient's body; if the orientation of the relevant tubing needs to be adjusted, the driving end of the adjusting rope is driven by the driving component to move away from the free end of the channel tube 100 (the adjusting rope remains taut), causing the free end of the channel tube 100 to rotate towards the side where the adjusting rope is being pulled (deformation groove 101 deforms), thus achieving the purpose of adjusting the orientation of the tubing. When resetting is required, the driving end of the adjusting rope is driven by the driving component to move closer to the free end of the channel tube 100, and the channel tube 100 returns to its original position (the channel tube 100 can be supported by an elastic material). In this way, the orientation of the channel tube 100 can be conveniently adjusted without the need for the entire adjustment device body, reducing harm to the patient.

[0037] As shown in Figure 3, in order to restrict the path of the adjustment rope and avoid interfering with the surgery or causing damage to the tissue, the channel tube 100 is provided with several limiting modules distributed from the free end to the installation end. Each limiting module consists of two limiting holes 102. The adjustment rope enters and exits the channel tube 100 through the two limiting holes 102 respectively. In other words, the adjustment rope passes through several limiting holes 102 sequentially from the free end of the channel tube 100 and is limited on the channel tube 100.

[0038] Further optimization involves providing several adjustment ropes to improve the freedom of the free end orientation adjustment of the channel tube 100. These ropes are positioned in different circumferential directions of the channel tube 100. Additionally, each adjustment rope has several limiting holes 102 on its side to limit the movement of the ropes.

[0039] As shown in Figures 3-5, in this embodiment, four adjusting ropes are preferably provided. These four adjusting ropes are evenly distributed circumferentially around the channel tube 100 (in this embodiment, the four adjusting ropes are respectively located on the first, second, third, and fourth sides of the channel tube 100; the first and third sides are on opposite sides in the horizontal direction, while the second and fourth sides are on opposite sides in the vertical direction). To drive the four adjusting ropes, the driving component includes a first turntable 200 and a second turntable 300. Both the first turntable 200 and the second turntable 300 are rotatably mounted on the device body. The rotation axes of the first turntable 200 and the second turntable 300 are different from the extension direction of the channel tube 100. Preferably, the rotation axis of the first turntable 200 is oriented horizontally, and the rotation axis of the second turntable 300 is oriented horizontally. The rotation axis of 00 is preferably set in the vertical direction; the driving ends of the two adjusting ropes (the second side and the fourth side) are respectively connected to different angles in the circumferential direction of the first turntable 200; the driving ends of the other two adjusting ropes (the first side and the third side) are respectively connected to different angles in the circumferential direction of the second turntable 300. In this way, by rotating the first turntable 200, one of the adjusting ropes on the second side and the fourth side is dragged and the other is loosened, so that the free end of the channel tube 100 rotates towards the dragged side; the use of the second turntable 300 is the same as that of the first turntable 200; and, in order to facilitate the rotation of the first turntable 200 and the second turntable 300, a rudder 400 is coaxially provided on both the first turntable 200 and the second turntable 300, and the rudder 400 is located on the outside of the device body.

[0040] Further optimization involves providing an end cap 500 at the free end of the channel tube 100 to facilitate the limiting and fixing of the internal tubing. The end cap 500 has several mounting holes, with the tubing placed at different mounting holes. The end cap 500 also has a chamfered edge on its circumferential side to reduce damage to tissues when inserted into the patient's body.

[0041] Example 2: In addition to the above examples, this application also includes Example 2. The difference between Example 2 and the above examples is that the driving component includes several sliders (not shown in the figure). The sliders are slidably disposed on the device body. The sliding direction of the sliders is consistent with the extension direction of the channel tube 100. The free ends of several adjusting ropes are respectively connected to several sliders. In this way, by sliding the slider on the corresponding side, the corresponding adjusting rope is dragged, and the channel tube 100 is rotated towards that side, which is convenient and quick to use.

[0042] In summary, during installation, the relevant tubing is threaded through the channel tube 100; during use, the free end of the channel tube 100 is inserted into the patient's body; if the orientation of the tubing needs to be adjusted, the driving end of the adjusting rope is moved away from the free end of the channel tube 100 by the driving component, causing the free end of the channel tube 100 to rotate towards the side where the adjusting rope is being pulled, thus adjusting the orientation of the tubing. When resetting is required, the driving end of the adjusting rope is moved closer to the free end of the channel tube 100 by the driving component, and the channel tube 100 returns to its original position. In this way, the orientation of the channel tube 100 can be easily adjusted without the need for the entire adjustment device body, reducing harm to the patient.

[0043] 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.
