Description

Technical Field

[0001] The utility model relates to the technical field of skull repair, and more specifically to a skull support repair capsule. Background Art

[0002] In neurosurgery, decompressive craniectomy is often required due to severe craniocerebral trauma, large-area cerebral infarction, cerebrovascular disease, postoperative malignant brain swelling, tumors, etc. Long-term craniectomy can cause skin depression, facial changes, brain tissue necrosis, etc. In severe cases, abnormal brain herniation may occur, which is life-threatening. Therefore, such patients need cranioplasty to reconstruct the bone structure, restore the appearance, establish a pressure-resistant structure, maintain the balance between intracranial pressure and atmospheric pressure, and improve brain perfusion. However, the timing of cranioplasty is also an important factor affecting postoperative recovery.

[0003] Studies have shown that early cranioplasty within 30 days after decompressive craniectomy may increase the risk of infection, deterioration of neurological function, epileptic seizures, and bone flap resorption; late cranioplasty more than 90 days after decompressive craniectomy can reduce the risk of hydrocephalus. Therefore, the best time period for cranioplasty is 3-6 months after decompressive craniectomy. While waiting for cranioplasty, the brain is directly exposed to atmospheric pressure, which can cause symptoms such as postural headaches, paresthesias, and cranial nerve palsies. At the same time, changes in cerebrospinal fluid, blood flow, and other dynamics can cause problems such as subdural effusion and decreased brain metabolism. Currently, there is a lack of a repair device that can cover the dura mater and close the skull gap immediately after surgery.

[0004] The Chinese patent discloses a skull repair system, including a repair body formed of a polyetheretherketone material, a patch on the repair body, the patch including an extension portion for connecting the repair body and the autologous skull, and the patch and the repair body are integrally formed. Since the skull repair system includes a patch for connecting the repair body and the autologous skull, other connecting components are no longer required to connect the repair body and the autologous skull during surgery, so the skull repair system of the utility model is more convenient to use. However, this technical solution is aimed at the implementation of skull repair surgery, and it is not possible to close the skull gap while waiting for the skull repair surgery. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a skull support repair capsule, which can avoid prolonged exposure of the brain after decompressive craniectomy and improve the efficiency of subsequent skull repair.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A skull support repair capsule is provided, comprising a main capsule body and a fixing part, wherein a cavity is arranged inside the main capsule body, an injection port communicating the cavity with the outside is arranged on the side wall of the main capsule body, and the fixing part is fixedly arranged on the periphery of the main capsule body.

[0008] With this arrangement, when the skull gap needs to be temporarily closed after decompressive craniectomy, the main capsule can be fixed to the skull gap through the fixing part to complete the skull closure, which greatly improves the efficiency of skull repair and closure; when skull repair is needed after 90 days, plastic materials such as bone cement or PLGA injectable gel can be injected into the cavity inside the main capsule through the injection port, and a hard bone piece is formed after the plastic material solidifies, which greatly facilitates the subsequent surgery and improves the efficiency of skull repair.

[0010] Through this arrangement, the skin-friendly layer on the outside of the main capsule can reduce the irritation of the main capsule to the surrounding skull; the sealing lining layer can ensure that the plastic material injected into the main capsule does not leak; the shaping structure layer can improve the structural strength of the main capsule wall, ensuring that the main capsule has a certain flexibility so as to fit the skull, and that the main capsule has a certain toughness to avoid collapse of the main capsule due to weight after the plastic material is injected; the anti-adhesion layer can prevent the cavity walls inside the main capsule from adhering to each other, which is conducive to the plastic material fully filling the main capsule.

[0011] Preferably, the main bladder body is divided into an upper bladder and a lower bladder, the upper bladder and the lower bladder are detachably connected, the fixing portion is fixedly installed at the bottom of the lower bladder, and the injection port is installed at the side of the lower bladder.

[0012] With this arrangement, when installing the main capsule body, the lower capsule can be first placed on the skull to facilitate positioning, and then the upper capsule and the lower capsule can be connected to form the main capsule body.

[0013] Preferably, an upper connecting ring is provided on the periphery of the upper bag, a lower connecting ring is provided on the periphery of the lower bag, the upper connecting ring is provided with a plurality of grooves, the lower connecting ring is provided with a plurality of buckles corresponding to the grooves one by one, the upper bag and the lower bag are detachably connected via the upper connecting ring and the lower connecting ring; the fixing part and the injection port are both provided on the lower connecting ring.

[0014] Through this arrangement, when the upper bag is connected to the lower bag, the groove on the upper connecting ring and the buckle of the lower connecting ring correspond one by one in the vertical direction, the upper connecting ring is pressed down to abut against the lower connecting ring, and the buckle is buckled into the groove, so that the upper connecting ring and the lower connecting ring are tightly connected to prevent the upper connecting ring and the lower connecting ring from separating or rotating.

[0015] Preferably, the upper connecting ring is provided with a plurality of upper ventilation holes, and the lower connecting ring is provided with a plurality of lower ventilation holes, the positions of the upper ventilation holes correspond to the lower ventilation holes one by one, and the plurality of upper ventilation holes are respectively connected with the plurality of lower ventilation holes to form a ventilation channel running through the upper connecting ring and the lower connecting ring.

[0016] With this setting, after the upper sac is connected to the lower sac and plastic material is injected to seal the skull, the inside of the skull can exchange gas with the outside of the repair sac through the ventilation channel formed by the upper vent and the lower vent, avoiding the occurrence of subdural effusion, not affecting the postoperative intracranial pressure, and helping to ensure the normal function of the brain.

[0017] Preferably, the fixing portion includes a plurality of fixing plates, through holes are formed on the fixing plates, and the fixing plates are evenly distributed along the outer side of the lower connecting ring.

[0018] With this arrangement, when the lower sac needs to be connected and fixed to the skull, screws and other connecting parts can be passed through the through holes and inserted into the skull, thereby fixing the lower sac on the skull to ensure a firm connection; evenly spaced fixing plates can make the lower connecting ring bear force evenly, further improving the stability of the installation.

[0019] Preferably, a plurality of flow channels are provided on the inner side of the lower bag, and the flow channels are used to guide the flow of the plastic material.

[0020] Through this setting, when shaping materials such as bone cement are injected, the bone cement will flow along the path formed by the flow channel in the main balloon, so that the bone cement can fill the main balloon along the preset path, effectively avoiding the accumulation of bone cement in local areas of the main balloon.

[0021] Preferably, it also includes an adjustment component and an elastic frame, wherein the adjustment component is installed at the geometric center of the upper capsule and the lower capsule, and the elastic frame is installed in the upper capsule. The elastic frame is used to support the upper capsule to arch, and the adjustment component is used to adjust the distance between the upper capsule and the lower capsule.

[0022] With this arrangement, the elastic frame can prop up the upper sac into an arc-shaped structure. When a subsequent cranioplasty is performed, the doctor can adjust the distance between the upper sac and the lower sac by adjusting the component according to the curvature of the user's skull, thereby compressing the elastic frame to reduce the curvature of the upper sac; when the elastic frame is compressed, the elastic force increases, and the elastic force is transmitted to the lower sac through the adjusting component, increasing the curvature of the lower sac, thereby changing the distance and curvature of the cavity between the upper sac and the lower sac. After the plastic material is injected, a skull repair piece that matches the patient's skull can be formed to prevent the main sac from collapsing downward when the plastic material is injected, causing a scalp depression, thereby avoiding affecting the patient's postoperative mental health due to the unsightly scalp depression.

[0024] With this arrangement, when it is necessary to adjust the cavity structure between the upper capsule and the lower capsule, it is only necessary to change the position of the adjusting nut on the adjusting screw by turning the adjusting nut on the adjusting screw. The upper capsule is in close contact with the adjusting nut under the action of the elastic frame. When the adjusting nut moves, the upper capsule is compressed by the adjusting nut and the curvature is changed. At the same time, the adjusting nut transfers the force received to the lower capsule through the adjusting screw. The middle part of the lower capsule is subjected to an upward force, and the curvature of the lower capsule becomes larger, thereby changing the cavity structure inside the upper and lower capsules.

[0025] Preferably, the adjustment assembly includes two adjustment nuts, both of which are threadedly connected to the adjustment screw and are located outside the upper bag.

[0026] With this arrangement, the two adjusting nuts are limited to each other, which can ensure that the adjusting nuts are not easily displaced on the adjusting screw, thereby improving safety.

The upper connecting ring is provided with a plurality of guide paths, and the ends of the plurality of elastic ribs are movably arranged on the outside of the upper bag and are movably arranged on the plurality of guide paths respectively.

[0030] Through this arrangement, when the elastic frame is compressed by adjusting the nut to change the distance between the upper capsule and the lower capsule, the elastic ribs extend along the guide path and then curl upward to prevent the elastic ribs from piercing nearby tissues; after the curvature of the main capsule body is determined, the excess elastic ribs extending out of the guide path are cut off, which can not only achieve the purpose of elastic adjustment, but also avoid excessive stress in the upper capsule after the elastic frame is deformed, thereby increasing the service life of the upper capsule.

[0031] Preferably, a sealing strip is provided at the bottom of the upper bag, and a sealing groove is provided at the top of the lower bag, and the sealing strip can be embedded in the sealing groove.

Through this arrangement, the sleeve can prevent the repaired plastic material from leaking from the adjusting screw.

[0033] Preferably, the skin-friendly layer is a skin-friendly medical braided fabric.

[0034] Furthermore, the material of the skin-friendly layer is a synthetic polymer fiber material with excellent biocompatibility, including but not limited to polypropylene (PP), polytetrafluoroethylene (PTFE), polyester (PET), polylactic acid (PLA), polyethylene (PE), etc.
