Description

Technical Field

[0001] The present invention relates to the technical field of hydrocephalus drainage, in particular to a hydrocephalus drainage device. Background Art

[0002] Hydrocephalus is a general term for an obstruction in the production or circulation and absorption of cerebrospinal fluid, which results in an excess of cerebrospinal fluid and increased pressure, expanding the space normally occupied by cerebrospinal fluid, and thus leading to increased intracranial pressure and ventricular enlargement. Clinically, children often experience enlarged head, enlarged and tense fontanelles, delayed healing of cranial sutures, sunset eyes, vomiting, convulsions, language and movement disorders, and mental retardation. Adults often experience intermittent headaches, head swelling, heaviness, dizziness, tinnitus, ear congestion, decreased vision, and weakness in the limbs.

[0003] In addition to hydrocephalus caused by normal lesions, sequelae of some diseases and surgical treatments will also cause hydrocephalus. During the treatment of most cases of hydrocephalus, a drainage device is needed to drain the accumulated fluid.

[0004] Devices for drainage of hydrocephalus are widely used in hospitals. Most hydrocephalus drainage requires draining out cerebrospinal fluid through a drainage tube to relieve intracranial pressure, and then surgery is performed or a shunt is implanted in the body to treat hydrocephalus. Most of these hydrocephalus drainage devices directly drain by inserting a drainage needle into the brain. However, the needle body of this direct insertion is relatively thin and there is no positioning mechanism for fixing it outside the head. As a result, during the drainage process, both the doctor and the patient are likely to touch the drainage needle. At the same time, the rotation of the patient's head and the influence of the needle's own gravity may cause the drainage needle to deviate. Summary of the invention

[0005] The purpose of the present invention is to provide a hydrocephalus drainage device to solve the problem that the existing hydrocephalus drainage device directly inserts a drainage needle into the brain for drainage. The directly inserted needle body is thin and there is no positioning mechanism for fixing it outside the head. As a result, during the drainage process, both the doctor and the patient are likely to touch the drainage needle tube. At the same time, the rotation of the patient's head and the influence of the gravity of the needle tube itself may cause the drainage needle tube to deviate.

[0031] Embodiment 1

[0032] Reference Figure 1-7A hydrocephalus drainage device, in order to locate the position of the drainage structure outside the patient's brain and stabilize the entire drainage structure to prevent safety problems caused by bumps, rotation of the patient's head and the influence of the gravity of the needle tube itself, is provided here including a basic sleeve frame 1, the basic sleeve frame 1 is an arc frame, and mounting frames 2 are provided at both ends of the basic sleeve frame 1, and the mounting frames 2 are provided with an external ear locking mechanism 3 that can rotate, and the external ear locking mechanisms 3 on the two mounting frames 2 are mirror-symmetrical, so that after the external ear locking mechanism 3 is locked at the position outside the patient's ear, the position of the basic sleeve frame 1 on the external ear locking mechanism 3 can be rotated to adjust the position of the basic sleeve frame 1 outside the patient's head;

[0033] The regulating mechanism 4 includes a basic movable block 41 and an auxiliary clamping assembly 42. The basic movable block 41 is slidably installed on the basic sleeve frame 1 along the arc-shaped frame body of the basic sleeve frame 1, and a locking member 5 is provided at the connection between the basic movable block 41 and the basic sleeve frame 1. The locking member 5 is a common nut screwed into the locking structure, which is not described here. When the basic movable block 41 slides on the basic sleeve frame 1, the position of the basic movable block 41 on the basic sleeve frame 1 can be locked by the locking member 5. The auxiliary clamping assembly 42 is provided on the basic movable block 41;

[0034] The basic sleeve frame 1 is a double-layer arc frame, and the basic movable block 41 is an arc block, and is slidably installed between the double-layer frame bodies of the basic sleeve frame 1;

[0035] The drainage component 6 is provided with a through slot on the basic movable block 41, and the drainage component 6 passes through the through slot of the basic movable block 41. The drainage component 6 includes a fixed sleeve 601 and a drainage needle 602. The drainage needle 602 is a metal needle body. The fixed sleeve 601 is sleeved on the outside of the needle body of the drainage needle 602. The auxiliary clamping component 42 acts on the drainage needle 602.

[0036] The opposing positioning mechanism 7 is arranged at the edge of the through groove of the basic movable block 41, and the opposing positioning mechanism 7 acts on the fixed sleeve 601, so that the opposing positioning mechanism 7 cooperates with the auxiliary clamping assembly 42 to respectively lock the positions of the fixed sleeve 601 and the drainage needle 602 on the basic movable block 41.

[0037] The opposing positioning mechanism 7 includes an installation side wall 71, a horizontal opposing extrusion component 72 and an inclined opposing extrusion component 73. The two installation side walls 71 are set in a group and are mirror-symmetrically arranged at the two side edges of the through-slot of the basic movable block 41. The horizontal opposing extrusion component 72 is arranged between the ends of the two installation side walls 71. The inclined opposing extrusion component 73 is arranged on the central wall body of the two installation side walls 71, and an angle is formed between the inclined opposing extrusion component 73 and the horizontal opposing extrusion component 72. By cooperating with the inclined opposing extrusion component 73 and the horizontal opposing extrusion component 72, an opposing triangular clamping is formed for the fixing sleeve 601 passing through the through-slot of the basic movable block 41, so that the fixing sleeve 601 can be fixed in the through-slot of the basic movable block 41 and locked in position.

[0038] Furthermore, the mounting side wall 71 includes an inclined wall obliquely arranged at the edge of the through-groove of the basic movable block 41 and a vertical wall vertically arranged at the end of the inclined wall. The horizontal opposite extrusion assembly 72 includes a movable extrusion frame 721 and an extrusion spring 722. The two movable extrusion frames 721 are a group of mirror-symmetrical ones and are respectively arranged on the vertical walls of the two mounting side walls 71. The extrusion spring 722 is arranged between the vertical wall and the movable extrusion frame 721, so that the two movable extrusion frames 721 maintain a tendency to move toward each other. The end of the movable extrusion frame 721 is an arc frame, which can better complete the extrusion of the fixed sleeve 601.

[0039] Furthermore, the inclined opposite extrusion assembly 73 includes an inclined extrusion frame 731 and a return spring 732. The inclined extrusion frames 731 are grouped together in two, and are movable through the inclined wall parts of the two mounting side walls 71 respectively. The return spring 732 is arranged between the inclined wall and the inclined extrusion frame 731, so that the inclined extrusion frame 731 maintains a tendency to tilt and slide, and the end of the inclined extrusion frame 731 is an arc frame.

[0040] In addition, the drainage needle 602 includes a drainage hose and a slender needle body arranged at the end of the drainage hose. The slender needle body portion of the drainage needle 602 passes through the fixed sleeve 601. The fixed sleeve 601 is a circular sleeve, and the curvature of the outer wall of the fixed sleeve 601 corresponds to the arc frame at the end of the movable extrusion frame 721 and the inclined extrusion frame 731. When the arc frame at the end of the movable extrusion frame 721 and the inclined extrusion frame 731 forms a triangular extrusion on the fixed sleeve 601, since the inclined direction of the inclined extrusion frame 731 is sideways and upward, the extrusion direction of the fixed sleeve 601 is sideways and upward. At this time, the fixed sleeve 601 will maintain a certain upward driving force, which is convenient for the subsequent pulling out of the fixed sleeve 601.

[0041] The auxiliary clamping assembly 42 includes a first clamping frame 421 and a second clamping frame 422. A slot connected to the through groove is opened on the block body of the basic movable block 41. The first clamping frame 421 and the second clamping frame 422 are both inserted in the slot, and the ends of the first clamping frame 421 and the second clamping frame 422 are both horizontally located in the through groove. The end frames of the first clamping frame 421 and the second clamping frame 422 are arc frames that cooperate with each other, so that when the first clamping frame 421 and the second clamping frame 422 are pulled and moved in opposite directions in the slot of the basic movable block 41, the arc frames at the ends of the first clamping frame 421 and the second clamping frame 422 will squeeze the drainage needle 602 passing through the through groove in opposite directions, lock the position of the drainage needle 602 passing through the through groove of the basic movable block 41, and prevent the drainage needle 602 from tipping over.

[0042] In this embodiment, when in use, the position of drainage insertion is first determined, and the basic sleeve frame 1 is clamped on the outside of the patient's ear by the outer ear locking mechanisms 3 on both sides of the basic sleeve frame 1. At this time, the position of the basic sleeve frame 1 outside the patient's head is adjusted, and then the basic movable block 41 is adjusted to be located at the position of drainage insertion on the patient's head by sliding the basic movable block 41 between the double-layer frames of the basic sleeve frame 1. At this time, the fixed sleeve 601 can be inserted into the through groove of the basic movable block 41. At this time, the fixed sleeve 601 will squeeze the arc frame at the end of the mirror-symmetrical active extrusion frame 721 and the inclined extrusion frame 731 to open. After the fixed sleeve 601 passes through the arc frame, under the action of the extrusion spring 722 and the return spring 732, the arc frame at the end of the active extrusion frame 721 and the inclined extrusion frame 731 forms a pair of the fixed sleeve 601. 1 is pressed in opposite triangles to position the fixed sleeve 601. At this time, the needle body of the drainage needle 602 passes through the fixed sleeve 601 and is inserted into the patient's brain for drainage. At this time, the first clamping frame 421 and the second clamping frame 422 in the slot of the basic movable block 41 can be pulled in reverse to allow the arc-shaped frames at the ends of the first clamping frame 421 and the second clamping frame 422 to press the drainage needle 602 passing through the through-slot against each other, and lock the position of the drainage needle 602 passing through the through-slot of the basic movable block 41. By positioning and limiting the fixed sleeve 601 and the drainage needle 602, the position of the drainage structure outside the patient's brain can be effectively positioned, and the needle part of the drainage structure can be stabilized to prevent the problem of needle deviation caused by bumps, rotation of the patient's head and the influence of the gravity of the needle tube itself.

[0043] Embodiment 2

[0044] like Figure 1-7As shown, this embodiment is basically the same as the first embodiment. Preferably, in order to facilitate the control of the rotation angle and adjust the position of the drainage part outside the patient's brain as needed, an angled scale is provided on the outer wall of the arc-shaped frame of the basic sleeve 1, one side of the basic movable block 41 exceeds the edge of the basic sleeve 1, and a pointing block facing the scale is provided on the protruding part of the basic movable block 41. Through the part of the basic movable block 41 that exceeds the edge of the basic sleeve 1, the entire basic movable block 41 can be easily moved to slide on the basic sleeve 1. At the same time, the pointing block on the basic movable block 41 can point to the scale on the basic sleeve 1 as the basic movable block 41 moves, so as to facilitate the observation and control of the rotation angle of the basic movable block 41.

[0045] The outer ear locking mechanism 3 includes a connecting ring 301, a locking spring 302 and a protective sleeve 303. The connecting ring 301 is arranged on the mounting frame 2. The protective sleeve 303 movably passes through the center of the connecting ring 301. The connecting ring 301 is provided with a locking member for locking the protective sleeve 303 after rotation. The locking member is a common structure for locking by screwing in a threaded column and squeezing. It will not be described here. The locking spring 302 is arranged between the protective sleeve 303 and the connecting ring 301, so that the protective sleeve 303 maintains a tendency to slide outward. When the basic sleeve 1 is put on the outside of the patient's head, the protective sleeve 303 is popped out by the locking spring 302, and the protective sleeves 303 on both sides are respectively squeezed on the outside of the patient's ears to stabilize the basic sleeve 1 on the outside of the patient's head. An angled scale is provided on the outer wall of the connecting ring 301, and a pointer is provided on the outer wall of the protective sleeve 303 facing the scale on the outer wall of the connecting ring 301. When the connecting ring 301 rotates on the protective sleeve 303, the rotation angle can be observed and controlled through the scale pointed by the pointer.

[0046] In this embodiment, the protective sleeve 303 is fitted to the outside of the ears on both sides of the patient's head, and under the compression of the locking spring 302, the protective sleeve 303 is tightly attached to the outside of the patient's ears. At this time, the connecting ring 301 can be rotated outside the protective sleeve 303 to drive the mounting frame 2 and the basic sleeve frame 1 to rotate synchronously to adjust the position of the basic sleeve frame 1 outside the patient's head. During the process, the outer wall pointer of the protective sleeve 303 can point to the angle scale on the outer wall of the connecting ring 301 to observe and control the rotation angle of the connecting ring 301. At the same time, the pointing block on the basic movable block 41 points to the scale on the basic sleeve frame 1 to observe and control the rotation angle of the basic movable block 41 on the basic sleeve frame 1. The rotation angle can be controlled, and the position of the basic movable block 41 outside the patient's brain can be controlled more conveniently and accurately.
