Description

Technical Field

[0001] The invention belongs to neurosurgery medical instruments, and in particular relates to a visual decompression brain puncture needle. Background Art

[0002] Cerebral hemorrhage is a critical and severe disease. How to quickly remove the hematoma and reduce intracranial pressure is the top priority to save the patient's life. Currently, all patients with cerebral hemorrhage need to undergo puncture and aspiration to remove the hematoma and reduce intracranial pressure. The purpose of puncture is to aspirate and remove the hematoma to reduce intracranial pressure and achieve the purpose of treatment. How to visualize puncture and aspiration to remove the hematoma and reduce intracranial pressure with minimal trauma is the ultimate goal pursued by every neurosurgeon. Avoiding repeated damage to brain tissue by using a sharp tip for multiple punctures, and puncturing, searching, and aspirating to remove the hematoma and reduce intracranial pressure under visual conditions are the best solutions to ensure minimal trauma. Due to the complex working conditions within the skull, the intricate interweaving of brain tissue, cranial nerves, and cerebral blood vessels, and the solid-state working environment, this goal is still not achievable.

[0003] The current patents include CN202023332226.1 (named: A visual puncture drainage device), CN202011537445.5 (named: A visual puncture device with convenient replacement of puncture head), CN202011518636.7 (named: A visual puncture device with good fixing effect), CN202011520012.9 (named: A visual puncture device with anti-slip structure), CN202011453675.3 (named: A visual puncture device with adjustable shooting angle), CN202010858207.8 (named: Visual puncture device and puncture device). Component), CN202021787635.8 (named: a visual puncture needle), CN202010255963.1 (named: a visual puncture device) are all designed for abdominal surgery, CN202011467200.X (named: a visual puncture device for preventing lens contamination), CN201620355131.6 (named: a visual puncture device), the working environment is used in a transparent gas or liquid phase, there is no corresponding zero-object-distance contact imaging technical solution, none of them can be used in solid-state brain tissue, and none of them has a technical solution to achieve visual reduction of intracranial pressure, and the purpose of surgical treatment cannot be achieved.

[0004] Patent CN201020292589.4 discloses a disposable visual decompression artificial abortion suction tube, whose working environment is viscous liquid or gas, and in the solid-like brain tissue, it is impossible to achieve zero-object-distance contact imaging. The air inlet 21 of the decompression tube is set at the rear end of the imaging lens of the endoscope in the main tube. The endoscope can only observe the front and cannot see the characteristics of the tissue entering through the hole 21. Once brain tissue instead of hematoma is inhaled, it will bring life-threatening danger to the patient. Its visualization is mainly for observing the residual situation of the embryo of the baby in the uterine cavity during abortion, rather than for decompression. The technical solution described in this patent cannot be used intracranially.

[0005] Patent CN201921535779.1 discloses a technical solution for clearing and decompressing intracranial hematomas without visual cerebral puncture, thus failing to achieve the fundamental purpose of surgical treatment for patients with cerebral hemorrhage. If hematoma clearance and decompression are required, other instruments must be used, which causes severe trauma, repeatedly damages brain tissue, and delays the best time for surgical treatment.

[0028] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise clearly indicated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprising" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations;

[0030] Definition of terms: The term “connected” in the description of the present invention where the head end of the visual module and the tail end of the transparent body are connected refers to being in contact or connected.

[0031] As described in the background art, the prior art has deficiencies. In order to solve the above technical problems, the present invention proposes a brain puncture needle.

[0032] In a typical embodiment of the present invention, Figure 1As shown, this embodiment discloses a novel brain puncture needle, which consists of a visual module 1, a visual channel tube 2, a suction channel tube 3, an outer tube 4, a homogeneous transparent body 6, a tail fixing device 5, and a flexible decompression tube core, wherein the visual channel tube 2 and the suction channel tube 3 are both sleeved in the outer tube 4; a homogeneous transparent body 6 is fixed to the head of the outer tube 4, a through hole 6-1 is provided in the homogeneous transparent body 6, and the head of the suction channel tube 3 is sealed and connected to the tail end of the through hole 6-1; the head of the visual channel tube 2 is also connected to the tail of the homogeneous transparent body 6, and a visual module 1 is provided in the visual channel tube 2, and the head end of the visual module 1 is connected to the tail end of the transparent body.

[0033] Furthermore, the homogeneous transparent body 6 is a solid cylindrical structure similar to a cylinder, but the head end of the cylindrical structure is curved and the tail end is flat, and a through hole 6-1 is provided in a direction parallel to the axial direction of the homogeneous transparent body 6, and the through hole 6-1 is eccentrically arranged in the homogeneous transparent body 6, as shown in FIG. Figure 3 The axis of the through hole 6-1 and the axis of the transparent body 6 are not on the same straight line. When assembled, the tail end of the homogeneous transparent body 6 is placed inside the head of the outer tube.

[0034] It should be noted that the outer tube 4 and the homogeneous transparent body 6 can be an integrally formed part or a split part. When they are split parts, they can be snapped together or welded together, but the firmness of the connection between the two must be ensured to prevent them from falling off during use.

[0035] Furthermore, the visual channel tube 2, the suction channel tube 3, the outer tube 4, and the homogeneous transparent body 6 can be integrally formed parts or split parts, depending on the actual processing technology.

[0036] Furthermore, the visual module 1 in this embodiment is an integral component, such as Figure 4 As shown, it is installed in the visual channel tube 2 as a whole and can be pulled out when not needed. Specifically, the visual module 1 is composed of a ring light 1-1 composed of multiple LEDs, an optical imaging lens 1-2, a micro CMOS image sensor 1-3, a base 1-4, a cable 1-5, a plug 1-6 and a metal tube 1-7; Figure 6As shown, a plurality of LEDs form a ring light 1-1 which is installed along the inner wall of a metal tube 1-7 at the head of the metal tube 1-7. An optical imaging lens 1-2 is installed at the center of the head of the metal tube 1-7. A micro CMOS image sensor 1-3 is fixed behind the optical imaging lens 1-2, and the micro CMOS image sensor 1-3 is fixed on a base 1-4. The base 1-4 is fixed inside the metal tube 1-7. The micro CMOS image sensor 1-3 is connected to a plug 1-6 via a cable 1-5. The specific working principle is as follows: a plurality of LEDs at the front end of the visual module form a ring light 1-1. The light is emitted and passes through the homogeneous transparent body 6 at the front end of the outer tube to reach the brain tissue or hematoma (lesion) at the head end of the transparent body. The light reflected by its annular end face enters the optical imaging lens 1-2 of the visual module through the homogeneous transparent body 6 at the front end of the outer tube of the soft drainage tube, and is sensed by the micro CMOS image photoreceptor 1-3 to form an image. The image is displayed on the display at the rear end via the signal line, realizing a contact imaging function, thereby realizing visual puncture and searching for hematomas. The syringe is connected to the Luer connector at the rear end of the suction channel extension tube, and visual aspiration of intracranial hematomas is realized within the field of view of the visual module, thereby performing an intracranial decompression operation. It should be noted that because the end face of the head of the visual module contacts or connects with the rear end of the homogeneous transparent body 6, the image is formed.

[0037] It should be further explained that the reason why a metal tube is used instead of a plastic transparent tube in the above-mentioned visual module 1 is that the wall thickness of the plastic transparent tube is limited by existing processes and materials, and the wall thickness thereof is larger than that of the metal tube. Therefore, the overall diameter will be thicker, and the size of the entire brain puncture needle will also increase. In actual surgical procedures, it is generally hoped that the size of the brain puncture needle is as small as possible to reduce damage to brain tissue. Therefore, the visual module 1 in this embodiment uses a metal tube 1-7 as its own outer tube.

[0038] Furthermore, the components of the above-mentioned visual module can also be designed as non-integral parts, that is, the above-mentioned metal tube 1-7 is eliminated, and the remaining components are directly installed in the visual channel tube 2. This can reduce the diameter of the overall brain puncture needle and reduce trauma. At this time, the visual module includes a ring light 1-1 composed of multiple LEDs, an optical imaging lens 1-2, a micro CMOS image sensor 1-3, a base 1-4, a cable 1-5, and a plug 1-6; the ring light 1-1 composed of multiple LEDs is installed on the head of the visual channel tube 2 along the inner wall of the visual channel tube 2, the optical imaging lens 1-2 is installed at the center position of the head of the visual channel tube 2, the micro CMOS image sensor 1-3 is fixed behind the optical imaging lens 1-2, and the micro CMOS image sensor 1-3 is fixed on the base 1-4; the base 1-4 is fixed in the visual channel tube 2; the micro CMOS image sensor 1-3 is connected to the plug 1-6 through the cable 1-5.

[0039] Furthermore, a fixing device 5 is fixed at the tail end of the outer tube 4, the visual channel tube 2, and the suction channel tube 3. The suction channel tube 3 is connected to the extension tube at its rear end, and the tail end of the extension tube is provided with a Luer connector, which is used to be connected to the syringe. This device can directly draw out hematoma under visual conditions to perform intracranial decompression.

[0040] Furthermore, during the puncture process, a suction channel tube core can be placed in the suction channel tube 3. The head end of the suction channel tube core is adapted to the arc shape of the front end of the through hole in the homogeneous transparent body 6, and forms an arc surface with the arc-shaped head end of the homogeneous transparent body 6 (it cannot protrude from the arc-shaped head end of the transparent body); the purpose of arranging the suction channel tube core in the suction channel tube of the present invention is to block the through hole of the transparent head to prevent damage to brain tissue during the puncture process.

[0041] Furthermore, the brain puncture needle body in this embodiment is also provided with scale lines, that is, scale lines are provided on the outer surface of the outer tube 4, and the length of the intracranial hematoma in this direction is measured by the scale lines on the needle body.

[0042] Furthermore, in this embodiment, the tail end of the brain needle body is provided with an image of a positive direction mark, which is used to determine whether the relative direction of the brain needle is consistent with the brain when the brain needle is fine-tuned up and down or left and right in the hematoma. Specifically, the positive direction mark can be designed at the tail end of the outer tube 4 or on the fixing device 5.

[0043] The use process of the present invention is as follows:

[0044] Before the operation, the puncture direction, path and depth are determined, the visual module is inserted into the visual channel tube, the suction channel tube core is inserted into the suction channel tube until the transparent body head end, the tail end of the suction channel tube core and the tail end of the suction channel tube are fixed into a whole, and the lesion is punctured along the puncture direction. During the puncture process, the image of the contact surface of the puncture needle head end is displayed on the rear end display, which the doctor uses to judge whether the hematoma position has been reached. The length of the hematoma in this direction is measured by the needle body scale line, and the brain needle head end is adjusted to be in the center of the hematoma. Then, the suction channel tube core is extracted, and then the syringe and the Luer connector at the rear end of the extension tube are connected. Under visual conditions, the hematoma is directly extracted through the through hole 6-1 to perform intracranial decompression. The present invention shortens the operation time as a whole, and the operation is safer; the operation is simple, fast and dexterous; the cost is low and it is easy to promote.

[0045] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
