Description
Technical Field
[0001] The utility model belongs to the technical field of nerve catheters, in particular to a nerve catheter with a fixed structure. Background Art
[0002] Neurosurgery is a branch of surgery that uses surgery as the main treatment method in surgery and applies unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, as well as their related subsidiary organs.
[0003] Most existing nerve catheters are simply laid when in use, and the catheters are all piled up in one place, causing the catheters to tangle with each other. When a single catheter needs to be removed or pulled out, the entanglement makes the catheter unable to move, which may cause medical accidents in severe cases. For this reason, we provide a nerve catheter with a fixed structure. Utility Model Content
[0004] The purpose of the utility model is to provide a nerve catheter with a fixed structure. The catheters can be separated by a ring to prevent them from being piled up together and entangled, which affects subsequent operations. The utility model solves the problem that the existing catheters are all piled up in one place, causing the catheters to be entangled with each other. When a single catheter needs to be taken out or pulled out, the catheter cannot be moved due to the entanglement, which may cause medical accidents in serious cases.
[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0006] The utility model is a nerve conduit with a fixed structure, comprising an adjustment mechanism and a movable plate.

[0007] The top and bottom of the connecting plate are rotatably connected to connecting rods, and the other end of the connecting rod is rotatably connected to a clamping block. The end of the clamping block away from the connecting rod passes through the movable block and extends to the outside. The front of the movable block is fixedly connected to a ring, and a shrinkage groove is opened inside the ring. The ring can be used to separate the catheters to prevent them from piling up together and causing entanglement, which affects subsequent operations.
[0008] Furthermore, there are three contraction grooves in total, and the three contraction grooves are arranged in a circular array with the ring as the center. The parts contained in the three contraction grooves are the same. The inner wall of the contraction groove is slidably connected to a sliding rod, and a spring 1 is sleeved on the outer surface of the sliding rod. The end of the sliding rod away from the contraction groove is fixedly connected to an extrusion plate. When the spring 1 is squeezed, a reaction force is generated, which will cause the inner wall of the extrusion plate to contact the inner wall of the catheter, thereby ensuring the stability of catheter transportation.
[0009] Furthermore, the back of the extrusion plate is fixedly connected to the front of the spring, the front of the spring is fixedly connected to the inner wall of the ring, the left side of the connecting plate is fixedly connected to a connecting rod, the left side of the connecting rod passes through the movable block and extends to the outside, the left side of the connecting rod is fixedly connected to a pressing plate, the inner wall of the slide is provided with a card slot, the inner wall of the card slot is adapted to the outer surface of the card block, and the movable block is fixed by the cooperation between the card slot and the card block.
[0010] Furthermore, the fixing mechanism includes an insertion block fixedly connected to the back of the movable plate, a movable groove is opened inside the insertion block, the inner wall of the movable groove is slidably connected to the push block, a through hole is opened inside the movable plate, the back of the through hole passes through the movable plate and extends to the inside of the insertion block, and the movable plate is fixed by pushing the insertion block into the opened hole.
[0011] Furthermore, the front of the push block is rotatably connected to a threaded rod, the outer surface of the threaded rod is threadedly connected to the inner wall of the through hole, the inner wall of the threaded rod is slidably connected to a clamping rod, the front of the clamping rod passes through the movable plate and extends to the outside, and the bolt rod is driven to rotate by the rotation of the clamping rod, and the threaded rod will move toward the back when rotating.
[0012] Furthermore, a knob is fixedly connected to the front of the card rod, and sliders are fixedly connected to the left and right sides of the push block. A card block is slidably connected to the inner wall of the movable groove. There are two card blocks in total, and a T-shaped groove is provided on the side where the two card blocks are close to each other. The inner wall of the T-shaped groove is slidably connected to the outer surface of the slider. When the push block moves toward the back, it will drive the slider to slide inside the T-shaped groove, and at the same time push the card block to both sides, push it out of the insertion block, so as to fix the movable plate.
[0013] The utility model has the following beneficial effects:
[0014] 1. The utility model sets a collar, and the spring 2 rebounds to reset the connecting plate. When the connecting plate is reset, it pushes the connecting rod to make it straight, and pushes out the card block through the connecting rod to make it snap into the card slot to fix the collar. Then the catheter passes through the collar, and when the catheter passes through the collar, the extrusion plate is pushed outward, and the spring 1 is squeezed at the same time. The squeezing of the spring 1 will form a reaction force, which will make the inner wall of the extrusion plate contact with the inner wall of the catheter, thereby ensuring the stability of the catheter transportation. The catheter can be separated by the collar to prevent them from being piled up together and causing entanglement, which affects subsequent operations.
[0015] 2. The utility model sets a card block, pushes the insertion block into the opened hole, and then rotates the knob. The rotation of the knob drives the card rod to rotate, and then the card rod drives the threaded rod to rotate. When the threaded rod rotates, it will move toward the back. When the threaded rod moves to the back, it will push the push block to move, and then move to the back through the push block. When the push block moves to the back, it will drive the slider to slide inside the T-slot, and at the same time push the card block to both sides, push it out of the insertion block, to achieve the fixation of the movable plate. After the fixation is completed, the operation is simple and can be quickly installed and disassembled.
[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
