Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a neurosurgical catheter 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 injuries, inflammations, tumors, deformities, and certain genetic metabolic disorders or functional disorders, such as epilepsy, Parkinson's disease, and neuralgia, exploring their etiologies and pathogenesis. Neurosurgery is a highly specialized and sophisticated discipline that also explores new diagnostic, treatment, and preventative technologies. In neurosurgical procedures, neurosurgical catheters are typically used for drainage. Neurosurgical drainage uses these catheters to remove fluids accumulated in the intracranial cavity or spinal canals, such as blood, pus, secretions, and exudates, from the body.

Detailed Implementation

[0020] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figure 1-3 As shown, this embodiment provides a neurosurgical catheter device, including a mounting block 1, with straps 4 connected to both sides of the mounting block 1. A detachable connecting component is provided on the side of the straps 4 away from the mounting block 1. A catheter 2 is movably inserted through the mounting block 1. A pressing and disassembling component for fixing the catheter 2 is provided between the catheter 2 and the mounting block 1.

[0023] The installation block 1 can be easily fixed to the patient by using the strap 4 and the detachable connecting parts. The catheter 2 can be quickly fixed by pressing the disassembly part. The catheter 2 can be fixed and disassembled by pressing, which greatly facilitates the installation and disassembly of the catheter 2 and brings great convenience to actual use.

[0024] The scheme is further optimized. The pressing and disassembling component includes a pressing button 3 that is slidably mounted on the mounting block 1. A vertically set sliding groove is opened in the middle of the mounting block 1. The pressing button 3 is vertically slidably connected in the sliding groove. A sleeve 302 is fixedly connected to the bottom surface of the pressing button 3. The pressing button 3, the sleeve 302 and the outer wall of the guide tube 2 are slidably engaged. A pressing locking and releasing component is installed on the sleeve 302. A snap-fit ​​component is provided on the side wall of the sliding groove. The snap-fit ​​component is engaged with the pressing locking component.

[0025] The scheme is further optimized. The pressing and locking release component includes a sliding block 301 that is slidably disposed on the outside of the sleeve 302. The sliding block 301 has a frustum structure with the small end of the sliding block 301 facing upward. A conical sleeve 303 is fixedly connected to the bottom surface of the sleeve 302. The conical sleeve 303 is slidably disposed on the outside of the guide tube 2 with the small end of the conical sleeve 303 facing downward. The top surface of the conical sleeve 303 is engaged with the snap-fit ​​component. Several slits 305 are opened on the side wall of the conical sleeve 303. The lower part of the inner wall of the groove has a conical structure, and the conical structure is squeezed and engaged with the conical sleeve 303.

[0026] The design was further optimized by covering the small end of the tapered sleeve 303 with an elastic layer 304.

[0027] When it is necessary to fix the conduit 2, press down the button 3. The button 3 pushes the conical sleeve 303 downward. Since the side wall of the conical sleeve 303 has several slits 305, as the conical sleeve 303 moves downward, the part of the conical sleeve 303 with slits 305 will shrink, and the elastic layer 304 will gradually press the conduit 2. The elastic layer 304 is set to provide elastic movement for the button 3 to move. After the conical sleeve 303 is pushed to the appropriate position, the locking component will lock the conical sleeve 303, thus fixing the conduit 2.

[0028] The scheme is further optimized. The snap-fit ​​component includes at least two slide rods 102. A slide rod groove 101 is provided in the mounting block 1. The slide rods 102 are symmetrically arranged and slidably disposed in the slide rod groove 101. A sliding block 104 is fixedly connected to one end of the slide rod groove 101 near the conical sleeve 303. A clearance groove is provided in the mounting block 1 to allow the sliding block 104 to move. A spring 103 is sleeved on the outside of the slide rod 102. The spring 103 is located between the sliding block 104 and the bottom wall of the clearance groove.

[0029] The design has been further optimized by providing an inclined surface at the end of the sliding block 104 near the sleeve 302.

[0030] The inclined surface design of the sliding block 104 is to facilitate pushing the sliding block 104 open during the downward movement of the conical sleeve 303, so that the sliding block 104 can lock the conical sleeve 303. The spring 103 is set to push the sliding block 104 to move and lock the conical sleeve 303.

[0031] When it is necessary to disassemble the conduit 2, continue pressing the press button 3 downwards. The press button 3 pushes the sliding block 301 downwards. When the bottom edge of the sliding block 301 exceeds the bottom edge of the sliding latch 104, since the press button 3 is designed with a frustum-shaped structure, pull the press button 3 upwards. The press button 3 will push the sliding latch 104 outwards. The large end diameter of the press button 3 is the same as the large end diameter of the conical sleeve 303. Thus, as the press button 3 moves upwards, the conical sleeve 303 can also disengage from the sliding latch 104, thereby enabling the disassembly of the conduit 2. Figure 1 The height of the sliding block 104 can be set appropriately based on the actual movement of the button 3. Figure 1 The height shown in the diagram is merely a structural illustration for the convenience of demonstrating the structure of this utility model.

[0032] In a further optimized design, one end of a strap 4 away from the mounting block 1 is fixedly connected to a first Velcro 401, and the other end of a strap 4 away from the mounting block 1 is fixedly connected to a second Velcro 402. The first Velcro 401 and the second Velcro 402 are bonded to each other.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
