Description

Technical Field

[0001] The present invention relates to the technical field of neurosurgery, and in particular to a minimally invasive drainage auxiliary device for cerebral hemorrhage in neurosurgery. Background Art

[0002] It is well known that minimally invasive drainage of cerebral hemorrhage in neurosurgery is a minimally invasive surgical method that uses precise puncture and catheterization to remove intracranial hematoma. It is mainly used to treat diseases such as hypertensive cerebral hemorrhage and cerebral hemorrhage breaking into the ventricle. Under the premise of minimizing brain tissue damage, the hematoma is continuously or intermittently discharged through the drainage tube to reduce intracranial pressure and protect neurological function.

[0003] The specific steps of minimally invasive drainage surgery for cerebral hemorrhage are preoperative preparation, puncture and catheterization, and postoperative drainage management. This surgery has minimal trauma and does not require craniotomy. It has a fast postoperative recovery and a low risk of infection. After surgery, the drainage tube needs to be fixed with a self-adhesive elastic bandage. First, cut the bandage into an E shape, tear off one end of the release paper, and fix the drainage tube with a high-lift platform. Let the tape stick to the patient's head without tension and press it fully. Tear off the middle release paper, fold the end back, and wrap it around the drainage tube to fix it.

[0004] During the postoperative period of the minimally invasive drainage surgery for cerebral hemorrhage, the bandage used to fix the drainage tube on the patient's head needs to be replaced regularly. During the replacement process, the bandage needs to be disassembled and replaced with a new one and then wrapped and fixed again. The drainage tube will be touched many times during the process, causing certain discomfort to the patient. At the same time, the replacement process is more troublesome. Summary of the Invention

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1-5 , a minimally invasive drainage auxiliary device for cerebral hemorrhage in neurosurgery, is used to solve the problem that during the period of drainage tube retention after minimally invasive drainage surgery for cerebral hemorrhage, the bandage used to fix the patient's head drainage tube needs to be replaced regularly. During the replacement process, the bandage needs to be disassembled and replaced with a new one and then wrapped and fixed again. The drainage tube will be touched many times during the process, which will cause certain discomfort to the patient. At the same time, the replacement process is more troublesome.

[0027] As a further technical solution proposed by the present invention, it includes a mask bracket 1, and also includes: a first bracket 2, which is arranged on the mask bracket 1; a first bandage 1.4 and a second bandage 1.5 connected to each other are relatively arranged on the mask bracket 1; a first buckle 2.1 is provided on the first bracket 2; a second buckle 3.1 that matches the first buckle 2.1 is provided on the mask bracket 1; a limiting space is formed between the first buckle 2.1 and the second buckle 3.1, and the limiting space is used to limit the drainage tube 4, and also includes a second bracket 3, which is arranged on the mask On the mask bracket 1, the first bracket 2 and the second bracket 3 are both arc-shaped structures, and the second buckle 3.1 is located on the second bracket 3. Specifically, when fixing the patient's drainage tube after surgery, the mask bracket 1 is placed on the patient's face through the first bandage 1.4 and the second bandage 1.5, and then the first bracket 2 and the second bracket 3 on both sides of the mask bracket 1 are moved toward each other and brought closer until the first buckle 2.1 and the second buckle 3.1 on the two are snap-fitted. During the snap-fitting process, one side of the drainage tube will be limited respectively, such as Figure 3 As shown in the state, the device forms a limiting space that matches and limits the drainage tube when the first ring buckle 2.1 and the second ring buckle 3.1 are snapped together, thereby fixing the drainage tube. When disassembling, the respective brackets are moved to separate the two. The operation is convenient, and the contact with the drainage tube 4 is reduced, which weakens or even avoids the need to regularly replace the bandage used to fix the patient's head drainage tube. During the replacement process, the bandage needs to be disassembled and replaced with a new one and then wrapped and fixed again. The drainage tube will be touched many times during the process, causing certain discomfort to the patient.

[0028] In this embodiment, the first bracket 2 and the second bracket 3 are both elastic sheets. In order to improve the comfort of contact with the patient, the two brackets can be sleeved with medical silicone sleeves, which improves the comfort of contact with the patient's head. Secondly, the two brackets have a certain deformation ability under the capacity of the elastic sheet. Through a certain deformation ability, they can adapt to move toward or away from each other during installation and removal, which is convenient for medical staff to install or remove. Before installation, the mask bracket 1 is disinfected accordingly. Figure 3 As shown in the state, optionally, the lengths of the first buckle 2.1 and the second buckle 3.1 on the first bracket 2 and the second bracket 3 can be adjusted, specifically according to the needs of those skilled in the art. Preferably, the lengths of the two buckles are as follows: Figure 3As shown in the state, the drainage tube 4 is limited by merging the two ring buckles, and the length of the ring buckle is the length of the limited drainage tube 4; a semi-annular portion 6 is provided on the first ring buckle 2.1 and the second ring buckle 3.1, which is used to connect with the self-adhesive elastic bandage, that is, when the two ring buckles limit and fix the drainage tube 4, the medical staff can further fix the two ring buckles by wrapping the bandage around the semi-annular portion 6, thereby improving the stability of the two ring buckles when they are combined, that is, when the two semi-annular portions 6 are combined, the two are combined into an overall circular structure, which is convenient for medical staff to wrap the bandage, and secondly, the length of the two semi-annular portions 6 is set according to the needs of technical personnel in this field, that is, according to the width of the self-adhesive elastic bandage; it is known that the preoperative preparation for minimally invasive drainage surgery for cerebral hemorrhage is specifically CT positioning, that is, marking the maximum layer of hematoma, puncture target (avoiding important blood vessels and functional areas), designing the puncture path (usually through the forehead or temporal region, avoiding the lateral fissure vessels), local anesthesia + sedation, that is, the operation is performed under local anesthesia for awake patients, and general anesthesia can be used for comatose patients. The scalp incision is about 1 to 3 cm, and the catheter is punctured and placed. A hole (about 3 mm in diameter) is drilled with a skull drill, and the brain needle is punctured into the hematoma cavity. Part of the liquid hematoma is aspirated (the initial aspiration volume does not exceed 50% of the hematoma volume to avoid a sudden drop in intracranial pressure and rebleeding) and a soft drainage tube (such as a silicone tube with multiple holes at the front end) is inserted. The depth is appropriate for the end of the catheter to be located in the center of the hematoma. A sterile drainage bag is connected externally, and finally, postoperative drainage is performed. Management, continuous drainage: adjust the height of the drainage bag according to the location of the hematoma (for example, intraventricular drainage needs to be 10 to 15 cm higher than the external auditory canal to prevent excessive drainage), thrombolysis assistance: if the hematoma coagulates, inject urokinase through the drainage tube (5000 to 10000 U / time, open after clamping for 2 to 4 hours) to promote blood clot dissolution, 1 to 2 times a day, extubation indications: the drainage fluid becomes clear, CT shows that the residual hematoma is less than 10 ml, and the intracranial pressure is normal. The tube is usually extubated 3 to 7 days after surgery.

[0029] In another embodiment provided by the present invention, the first buckle 2.1 and the second buckle 3.1 are in a semicircular ring structure as a whole, and the first buckle 2.1 is provided with protrusions 2.2 opposite to each other, and the second buckle 3.1 is provided with a limit portion 3.2 that is engaged with each protrusion 2.2. Each extension frame 1.2 is provided with a hanging ring 1.3, and each hanging ring 1.3 is in a semicircular ring structure as a whole. Each protrusion 2.2 is specifically a rectangular structure, which is adapted to each limit portion 3.2. Figure 3 and Figure 5As shown in the state, the two buckles are snap-fitted with each other through the protrusion 2.2 and the limiting portion 3.2, and after the snap-fit is implemented, the first buckle 2.1 and the second buckle 3.1 limit and fix the drainage tube 4; when the patient gets out of bed and walks after the operation, the condition must be basically stable: vital signs (blood pressure, heart rate, respiration, body temperature) are stable, there are no frequent headaches, vomiting, worsening of consciousness and other symptoms of increased intracranial pressure, the amount of cerebral hemorrhage has been controlled, the color of the drainage fluid gradually becomes lighter (such as from bloody to light bloody or clear), the drainage volume is <50ml / 24h (the specific situation needs to be determined by the doctor), the patient is in a suitable state: conscious, able to cooperate with instructions (such as keeping the head stable when standing or walking), without severe limb hemiplegia, balance disorder or ataxia (such as muscle strength ≥ level 3, The patient must be able to support the body independently), have no serious complications (such as heart failure, respiratory failure, severe anemia, etc.), can tolerate short-term standing and walking, and the drainage tube management is controllable: the drainage tube is firmly fixed (such as double fixation with sutures + self-adhesive bandages), there is no bleeding or redness or swelling at the puncture site, the catheter scale mark has not shifted, the doctor has evaluated the position of the drainage tube (such as located within the ventricle or under the dura mater, not deep in the brain parenchyma), and the height of the drainage bag can be temporarily adjusted (clamp the drainage tube when getting out of bed to avoid backflow or excessive drainage), etc. After the above conditions are met, the specific precautions for getting out of bed and activities must be carried out under the guidance of medical staff: A doctor's evaluation is required for the first time getting out of bed: the attending physician will determine whether the drainage tube is in a "stable period" (such as 3 to 5 days after surgery, the hematoma clearance ≥50%), and prescribe bed activities. Doctor's order, family members accompany the whole process: 2 people are required to assist (1 person to support the patient, 1 person to properly fix the drainage tube and drainage bag), avoid activities alone, temporary treatment of drainage tube: clamp the drainage tube: use sterile clamps to clamp the drainage tube (10 cm close to the puncture point) before getting out of bed, the clamping time is ≤30 minutes, to prevent cerebrospinal fluid / hematoma fluid backflow or sudden change in drainage speed due to change in body position, drainage bag position management: fix the drainage bag at the waist (lower than the head but 10-15 cm above the drainage tube puncture point, the specific height is subject to doctor's orders), avoid dragging or folding the catheter, activity intensity and time control: step by step: sit up first (raise the head of the bed 30 degrees, maintain for 5-10 minutes, and stand up after no dizziness or palpitations), stand for 3-5 minutes without discomfort, and then walk slowly (5 minutes each time). ~10 minutes, 1-2 times a day), avoid excessive fatigue, and move gently: keep the head in a neutral position when walking, avoid lowering the head, turning the head or bending over (such as tying shoelaces) to prevent the drainage tube from being pulled and displaced; gently support the head fixation device with your hand when coughing or sneezing, real-time monitoring and emergency treatment: observe adverse reactions: if the headache worsens, nausea and vomiting, gait is unstable, and there is increased bleeding / exudate from the drainage tube during getting out of bed, stop activities immediately, lie flat and notify medical staff, and return to bed after treatment: restore the drainage bag height (10-15 cm higher than the puncture point) when lying in bed, open the clamped drainage tube, check whether the fixation device is loose, and record the drainage fluid volume and color changes. In summary, the core principles when patients get out of bed are safety first, individualized assessment, and both fixation and protection.

[0030] In this embodiment, both fixation and protection are emphasized. Before getting out of bed, the patient should confirm that the drainage tube 4 is firmly fixed. During the activity, the patient should focus on protecting the puncture point and the catheter on the head to avoid external impact or pulling. The hanging ring 1.3 on the mask bracket 1 allows the patient to restrain the drainage tube 4 when getting out of bed. Figure 2 As shown in the status, the drainage tube 4 is arranged to avoid the disorder of the drainage tube 4 affecting the patient's walking when getting out of bed. Furthermore, there are two hanging rings 1.3, which are respectively set on the mask bracket 1, so that medical staff can arrange the drainage tube 4 to the left or right according to the actual situation of the patient, that is, according to the drainage point of the patient.

[0031] In another embodiment of the present invention, the first bandage 1.4 and the second bandage 1.5 are respectively provided with a first adhesive portion 1.6 and a second adhesive portion 1.7. The first bandage 1.4 is bonded to the second adhesive portion 1.7 on the second bandage 1.5 through the first adhesive portion 1.6. Figure 2 As shown in the state, the first adhesive part 1.6 and the second adhesive part 1.7 are adhesive Velcro, which is bonded together by the fur surface and the hook surface, so that the first bandage 1.4 and the second bandage 1.5 are connected to fix the mask bracket 1 on the patient's head.

[0032] In order to improve the stability of the mask bracket 1 worn by the patient, in another embodiment provided by the present invention, a nose pad 1.1 is provided on the mask bracket 1. The mask bracket 1 is composed of an arc-shaped plate and two extension frames 1.2 connected to the arc-shaped plate. The nose pad 1.1 is in contact with the patient's nose bridge. The contact between the patient's nose bridge and the nose pad 1.1 provides certain support for the mask bracket 1, thereby improving its stability when worn on the patient's head. Furthermore, the mask bracket 1 and the nose pad 1.1 can be customized according to the patient's head, so that they can better fit the patient's head and be comfortable to wear.

[0033] In another embodiment of the present invention, each extension frame 1.2 is provided with a buckle portion 1.8, and each buckle portion 1.8 is provided with a chin strap 5, such as Figure 1 and Figure 2 As shown in the state, the chin strap 5 is first connected to the buckle part 1.8, and then the chin strap 5 is stretched to make it abut against the bottom of the patient's mandible, thereby improving the stability of the mask bracket 1 when worn. That is, the chin strap 5 is a medical bandage, which has a certain elasticity.

[0034] In this embodiment, after the patient wears the mask bracket 1, certain precautions must be taken, namely, key management points after surgery. The first point is the patient's position and activity: after surgery, lie flat or raise the head of the bed 15° to 30° to facilitate intracranial venous return; those who are conscious can sit up when the drainage tube is well fixed (doctor's evaluation is required) to avoid violent shaking of the head. The second point is drainage observation: record the color of the drainage fluid (bright red → dark red → light red → clear) and the amount (normal <200ml / day). A sudden increase or darkening of the color indicates rebleeding.

[0035] In summary, minimally invasive drainage for cerebral hemorrhage is an important means for neurosurgery to treat moderate cerebral hemorrhage. Through "precise puncture + continuous drainage + thrombolysis assistance", it strikes a balance between trauma and efficacy. Its core value lies in its suitability for patients who cannot tolerate craniotomy, and it can clear hematoma early and alleviate space-occupying effect. However, the indications must be strictly controlled, and the risk of complications must be reduced through standardized postoperative management (such as drainage tube care and blood pressure control). The specific plan needs to be individualized by technical personnel in this field based on the patient's age, amount of bleeding, bleeding site, and general condition.

[0036] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
