Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a neurosurgical device with a flexible tubing adjustment mechanism. 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 handheld devices with endoscopes to perform various procedures such as aspiration of blood, irrigation, and electrocoagulation to assist in the surgery.

[0004] In the prior art, the functions of aspirating blood and rinsing in the aforementioned handheld devices are mainly achieved through a tube extending from the device into the patient's body. For example, the medical visual aspiration tube disclosed in Chinese Patent Publication No. CN104548314A includes a hollow aspiration tube body. The front end of the aspiration tube body is closed. The front side of the aspiration tube body is provided with an image-taking window and an aspiration window that communicate with the interior of the aspiration tube body. The image-taking window is located in front of the aspiration window. A separator is provided between the image-taking window and the aspiration window. The separator has an image-taking part that closes the image-taking window to form a closed mounting cavity at the front end of the aspiration tube body. The image-taking part is made of a light-transmitting material. A camera facing the image-taking part is installed in the closed mounting cavity. A camera wire is connected to the camera, which extends longitudinally through the closed mounting cavity and into the aspiration tube body. The advantages of this medical visual aspiration tube are: high operational accuracy, allowing for direct visualization of the surgical site while performing aspiration. However, when adjusting the flow rate of blood aspiration during the process, it is usually necessary to adjust it on the device connected to the beginning of the tube, rather than directly by hand, which is very inconvenient.

[0005] In view of this, there is an urgent need for a neurosurgical device with a flexible tubing adjustment mechanism to solve the above problems. Utility Model Content

[0006] To help solve the problems existing in the prior art, this utility model provides a neurosurgical device with a flexible tubing adjustment mechanism, which adopts the following technical solution: a guide body, tubing, and adjustment mechanism; the tubing is inserted into the guide body;

[0007] The adjustment mechanism includes a limiting seat and a pressure rod. A first hole is provided on the guide body, and the pressure rod passes through the first hole. The limiting seat is located directly below the pressure rod, and a pipeline channel is formed between the limiting seat and the pressure rod. The pipeline passes through the pipeline channel.

[0008] The adjustment mechanism also includes a push rod. The guide body has a second hole, which is strip-shaped and extends in the same direction as the pipeline. The push rod passes through the second hole and is connected to the pipeline.

[0009] The first hole is strip-shaped, and its extension direction is consistent with the extension direction of the pipeline. The pressure rod and the push rod are fixedly connected by a fixing rod.

[0010] When the pressure rod slides within the first hole, it remains directly above the limiting seat.

[0011] The adjustment mechanism also includes a reset element, which is used to move the pressure rod closer to or away from the limit seat.

[0012] The reset element is an elastic element, which is used to apply a downward or upward thrust to the pressure rod.

[0013] The reset component includes a first magnet and a second magnet, with the first magnet disposed at the bottom of the pressure rod and the second magnet disposed on the limiting seat.

[0014] The bottom of the push rod is provided with a collar, which is sleeved on the ring side of the pipeline.

[0015] The limiting seat is provided with a limiting groove, and the pipeline is clamped in the limiting groove.

[0016] Two limiting grooves are provided, and the two limiting grooves are respectively provided at both ends of the pipeline channel.

[0017] The above-described structure of this utility model can achieve the following beneficial effects:

[0018] During use, because the tubing passes through a conduit channel, the flow rate is adjusted during surgery by changing the distance between the pressure rod and the limiting seat. When the pressure rod moves closer to the limiting seat until it compresses the tubing circumferentially, the cross-sectional area of ​​the liquid channel within the tubing gradually decreases, thus reducing the flow rate. Conversely, when the pressure rod moves further away from the limiting seat and gradually detaches from the tubing, the tubing deformation gradually decreases, the cross-sectional area of ​​the liquid channel within the tubing gradually increases, thus increasing the flow rate. This convenient adjustment of the tubing flow rate allows for timely intervention by the surgeon during surgery. Attached Figure Description

[0024] 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.

[0025] 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.

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0027] Reference Figure 1-3 A neurosurgical device with a flexible tubing adjustment mechanism includes: a guide body 100 (the guide body 100 includes a handle, a guide portion disposed at one end of the handle, and a guide channel disposed at one end of the guide portion), tubing 200, and an adjustment mechanism; the tubing 200 is inserted into the guide body 100 (inserted at the guide portion and the guide channel), and the tubing 200 can be used to deliver fluid (e.g., flushing water) into the patient's body, or to deliver fluid (e.g., blood) from the patient's body to the outside of the body, or two tubing 200 can be provided, each equipped with an adjustment mechanism;

[0028] The adjustment mechanism includes a limiting seat 300 and a pressure rod 400. The guide body 100 has a first hole 101, and the pressure rod 400 passes through the first hole 101. The limiting seat 300 is located directly below the pressure rod 400 (that is, the orthogonal projection of the pressure rod 400 in the direction of the limiting seat 300 is always on the limiting seat 300). There is a pipeline channel between the limiting seat 300 and the pressure rod 400, and the pipeline 200 passes through the pipeline channel.

[0029] Based on the above structure, during use, since the tubing 200 passes through the tubing channel, the flow rate of the tubing 200 is adjusted by changing the distance between the pressure rod 400 and the limiting seat 300 during the operation. When the pressure rod 400 moves closer to the limiting seat 300 until it compresses the circumferential section of the tubing 200 (the tubing 200 is either a flexible tube or a portion of the tubing 200 between the tubing channels is a flexible tube), the tubing 200 deforms, and the cross-sectional area of ​​the liquid channel within the tubing 200 gradually decreases, thereby reducing the flow rate of the tubing 200. Conversely, when the pressure rod 400 moves closer to the limiting seat 300, until it compresses the tubing 200 circumferentially (the tubing 200 is a flexible tube or a portion of the tubing 200 between the tubing channels), the tubing 200 deforms, and the cross-sectional area of ​​the liquid channel within the tubing 200 gradually decreases, thus reducing the flow rate of the tubing 200. As the pressure rod 400 moves away from the limiting seat 300 and gradually disengages from the tube 200, the deformation of the tube 200 gradually decreases, thereby increasing the cross-sectional area of ​​the liquid channel within the tube 200 and increasing the flow rate. This facilitates the adjustment of the flow rate in the tube 200, allowing doctors to operate promptly during surgery. Compared to adjusting the suction force by controlling the suction side hole of the operating handle, this application controls the flow rate by squeezing the tube 200 and controlling its deformation.

[0030] like Figure 2 and Figure 3 As shown, in some application scenarios, when the pipe 200 needs to extend outward from the guide body 100 so that the suspended end of the pipe 200 can accurately reach the target position, the adjustment mechanism also includes a push rod 500. The guide body 100 has a second hole 102, which is strip-shaped and extends in the same direction as the pipe 200. The push rod 500 passes through the second hole 102 and is connected to the pipe 200. Thus, by sliding the push rod 500 in the second hole 102, the pipe 200 slides in the guide body 100, thereby achieving the purpose of extending outward from or retracting the guide body 100, further improving the adaptability of the guide.

[0031] Further optimizations include, for example Figure 2 and Figure 3As shown, the first hole 101 is strip-shaped, and the extension direction of the first hole 101 is consistent with the extension direction of the tubing 200 (when the pressure rod 400 slides in the first hole 101, the pressure rod 400 is always located directly above the limiting seat 300 (that is, the orthogonal projection of the pressure rod 400 in the direction of the limiting seat 300 is always on the limiting seat 300)). The pressure rod 400 and the push rod 500 are fixedly connected by a fixing rod. In this way, the push rod 500 and the pressure rod 400 are a whole unit, which makes it convenient for doctors to adjust the flow rate and position of the tubing 200 at the same time. They only need to hold the guide body 100 and move the whole unit with their fingers.

[0032] like Figure 4 As shown, the adjustment mechanism also includes a reset component, which is used to move the pressure rod 400 closer to or further away from the limit seat 300. Specifically, the reset component can be an elastic element (not shown in the drawing, the elastic element can be a spring or a sheet, etc.), which is used to apply a downward or upward pushing force to the pressure rod 400. The reset component can also be a first magnet 600 and a second magnet 700. The first magnet 600 is disposed at the bottom of the pressure rod 400, and the second magnet 700 is disposed on the limit seat 300. The position of the pressure rod 400 is adjusted by means of the principle that like poles repel and unlike poles attract.

[0033] In conjunction with the reset component, the specific implementation structure of this application can be as follows: If the reset component is used to bring the pressure rod 400 closer to the limiting seat 300, then the elastic component is used to apply a downward pushing force to the pressure rod 400 or the magnetic poles of the first magnet 600 and the second magnet 700 on the side that are close to each other are opposite. In this way, without applying external force, the pressure rod 400 remains in the state of pressing the pipeline 200, keeping the pipeline 200 in the closed state. When it is necessary to open the pipeline 200, the pressure rod 400 needs to be pushed upward to overcome the elastic force or magnetic attraction, so that the flow rate of the pipeline 200 gradually increases; if the reset component... To move the pressure rod 400 away from the limit seat 300, the elastic element applies an upward thrust to the pressure rod 400, or the magnetic poles of the first magnet 600 and the second magnet 700 are the same on the side that are close to each other. In this way, without applying an external force, the pressure rod 400 remains away from the pipe 200, so that the pipe 200 is in the state of maximum flow. When it is necessary to adjust the flow of the pipe 200, the pressure rod 400 needs to be pushed down to overcome the elastic force or repulsive force, so as to squeeze the pipe 200, thereby gradually reducing the flow of the pipe 200 until the pipe 200 is closed.

[0034] like Figure 4 As shown, in order to facilitate the connection of the pipe 200, the bottom of the push rod 500 is provided with a collar 501. The collar 501 is sleeved on the ring side of the pipe 200. The collar 501 can be C-shaped, thereby locking the pipe 200.

[0035] like Figure 3As shown, in order to limit the pipe 200 at the pipe channel, a limiting groove 301 is provided on the limiting seat 300; a better option is to provide two limiting grooves 301, with the two limiting grooves 301 respectively located at both ends of the pipe channel, and the pipe 200 is locked in the two limiting grooves 301 to limit the pipe 200.

[0036] In summary, during use, since the tubing 200 passes through a tubing channel, the flow rate of the tubing 200 is adjusted by changing the distance between the pressure rod 400 and the limiting seat 300 during the operation. When the pressure rod 400 moves closer to the limiting seat 300 until it compresses the circumferential direction of the tubing 200, the tubing 200 deforms, and the cross-sectional area of ​​the liquid channel within the tubing 200 gradually decreases, thus reducing the flow rate of the tubing 200. Conversely, when the pressure rod 400 moves further away from the limiting seat 300 and gradually disengages from the tubing 200, the deformation of the tubing 200 gradually decreases, thereby increasing the cross-sectional area of ​​the liquid channel within the tubing 200 and increasing the flow rate of the tubing 200. This conveniently adjusts the flow rate of the tubing 200, facilitating timely operation by the surgeon during the operation.

[0037] 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.
