Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a channel tip of a neurosurgical device. 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] When using the handheld device, a guide tube is inserted into the patient's body. The guide tube contains an irrigation tube, endoscope, instrument tube, etc. For example, the medical visual suction tube disclosed in Chinese Patent Publication No. "CN104548314A" includes a hollow suction tube body. The front end of the suction tube body is closed. The front side of the suction tube body has an image-taking window and a suction window that communicate with the interior of the suction tube body. The image-taking window is located in front of the suction window. A separator is provided between the image-taking window and the suction window. The separator has the function of closing the image-taking window, thereby forming a closed mounting cavity at the front end of the suction tube body. Furthermore, the imaging unit is made of a light-transmitting material, and a camera facing the imaging unit is installed inside the sealed mounting cavity. The camera is connected to a camera wire that extends longitudinally through the sealed mounting cavity and into the suction tube. During operation, suction can be performed while directly viewing the surgical site. During use, the imaging unit (endoscopic lens) may become contaminated with bloodstains, etc., and is generally rinsed through the channel. However, since the rinsing fluid outlet faces the same direction as the imaging unit (endoscopic lens), the rinsing fluid cannot directly rinse the imaging unit (endoscopic lens), resulting in a poor rinsing effect and affecting the imaging effect of the imaging unit (endoscopic lens).

[0005] In view of this, there is an urgent need for a neurosurgical device with a channel tip 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 a neurosurgical device channel tip, which adopts the following technical solution, including: a tip body, wherein the tip body is provided with an endoscope channel and an irrigation channel extending in the same direction, and a guide end face is provided in the direction directly opposite to the outlet of the irrigation channel;

[0007] The guide end face extends at an angle from the position of the rinsing channel toward the outlet end of the endoscope channel.

[0008] The guide end face is disposed inside the head end body, and a guide channel is disposed below the guide end face. One end of the guide channel is connected to the flushing channel, and the other end extends toward the outlet of the endoscope channel.

[0009] The head end body is provided with a baffle at one end of the outlet of the rinsing channel, and the guide end face is provided on the side of the baffle close to the rinsing channel.

[0010] A column connected to the head end body is provided on the side of the guide end face away from the endoscope channel, and the baffle is provided on the column.

[0011] The head end body is provided with a suction channel.

[0012] The head end body is provided with an instrument channel.

[0013] The head end body consists of a plug end and an end cap disposed at one end of the plug end. The end cap is provided with an annular limiting step surface on the annular side of the plug end.

[0014] The end face of the end cap away from the insertion end is an arc surface.

[0015] A positioning strip is provided on the ring side of the plug end.

[0016] The head end body is made of liquid crystal polymer or glass fiber.

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

[0018] In use, the head end is installed at the end of the guide tube, the endoscope is placed inside the endoscope channel, and the end of the flushing tube is installed inside the flushing channel. When it is necessary to clean the endoscope surface, the flushing fluid from the flushing tube flows out from the flushing channel. Since the guide end is positioned directly in front of the flushing fluid and extends at an angle towards the endoscope surface, the flushing fluid is guided to one side of the endoscope surface, which can directly flush the endoscope surface inside the endoscope channel, improving the flushing effect and thus improving the imaging effect, which helps to improve the efficiency and accuracy of the surgery.

[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] Example 1: Refer to Figure 1-2 A neurosurgical device channel tip includes: a tip body, an endoscope channel 100 and an irrigation channel 200 extending in the same direction are provided on the tip body, and a guide end face 300 is provided in the direction directly opposite to the outlet of the irrigation channel 200.

[0028] The guide end face 300 extends obliquely from the position of the flushing channel 200 toward the position of the endoscope channel 100 toward the outlet end of the endoscope channel 100 (that is, the guide end face 300 extends toward the endoscope surface inside the endoscope channel 100).

[0029] Based on the above structure, in use, the head end is installed at the end of the guide tube, the endoscope is placed within the endoscope channel 100, and the end of the irrigation tube is installed within the irrigation channel 200. When it is necessary to clean the endoscope surface, the irrigation fluid from the irrigation tube flows out from the irrigation channel 200. Because the guide end face 300 is positioned directly in front of the irrigation fluid and extends obliquely towards the endoscope surface, the irrigation fluid is guided to one side of the endoscope surface, directly rinsing the endoscope surface within the endoscope channel 100. This improves the irrigation effect, thereby improving the imaging effect and enhancing the efficiency and accuracy of the surgery. The irrigation fluid can be Ringer's solution or physiological saline.

[0030] like Figure 2 As shown, the guide end face 300 is disposed inside the head end body (one side of the guide end face 300 is connected to the circumferential side of the flushing channel 200). A guide channel 400 is disposed below the guide end face 300. One end of the guide channel 400 is connected to the flushing channel 200, and the other end extends toward the outlet of the endoscope channel 100. In this way, the flushing fluid from the flushing channel 200 passes through the obstruction of the guide end face 300 and enters the guide channel 400, and then reaches the outlet of the endoscope channel 100 to complete the cleaning of the endoscope surface (during this process, the flushing fluid rushes from the oblique rear of the head end body toward the end face of the head end body).

[0031] Furthermore, the head unit can be configured with suction channels and instrument channels according to usage requirements.

[0032] like Figure 1 and Figure 2 As shown, the head end body consists of a plug end 700 and an end cap 800 disposed at one end of the plug end 700. The end cap 800 is provided with an annular limiting step surface 801 on the annular side of the plug end 700. Thus, during installation, the plug end 700 is inserted into the end of the guide pipe, and the annular limiting step surface 801 fits against the end of the guide pipe to limit the installation of the head end body. In addition, a positioning strip 900 is provided on the annular side of the plug end 700. The position of the positioning strip 900 is adapted to the positioning notch at the end of the guide pipe, further improving the installation efficiency of the head end body.

[0033] Further optimizations include, for example Figure 1 As shown, in order to reduce damage to tissues when inserted into the patient's body, the end of the end cap 800 away from the insertion end 700 is an arc surface, that is, the end face of the end cap 800 has no sharp edges, and the circumferential side of the end cap 800 is chamfered.

[0034] Further optimization is that the head body can be made of LCP liquid crystal polymer, glass fiber, TPU polyurethane, PEEK polyether ether ketone or PC polycarbonate.

[0035] In addition to the embodiments described above, this application also includes an embodiment two, such as... Figure 3 and Figure 4 As shown, the difference between Embodiment 2 and the above embodiment is that: a baffle 500 is provided at the outlet end of the flushing channel 200 of the head body, and a guide end face 300 is provided on the side of the baffle 500 close to the flushing channel 200; and a column 600 connected to the head body is provided on the side of the guide end face 300 away from the endoscope channel 100, and the baffle 500 is provided on the column 600. In this way, when the flushing fluid rushes out from the flushing channel 200, it is blocked by the baffle 500 and guided by the guide end face 300 to the outlet end of the endoscope channel 100 (during this process, the flushing fluid is turned back and rushes towards the end face of the head body).

[0036] In summary, during use, the head end is installed at the end of the guide tube, the endoscope is placed in the endoscope channel 100, and the end of the irrigation tube is installed in the irrigation channel 200. When it is necessary to clean the endoscope surface, the irrigation fluid from the irrigation tube flows out from the irrigation channel 200. Since the guide end face 300 is positioned directly in front of the irrigation fluid and extends obliquely towards the endoscope surface, the irrigation fluid is guided to one side of the endoscope surface, which can directly irrigate the endoscope surface in the endoscope channel 100, improving the irrigation effect, thereby improving the imaging effect and increasing the efficiency and accuracy of the surgery.

[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.
