Abstract
Description
Technical Field
[0001] This application relates to the field of medical devices, and in particular to a special support headgear for interventional procedures. Background Technology
[0002] Interventional procedures are a minimally invasive diagnostic and treatment technique that involves inserting specialized catheters, guidewires, and other instruments into the body under the guidance of medical imaging equipment to diagnose and treat lesions. Interventional procedures are often performed using cervical puncture or non-cervical puncture methods.
[0003] Currently, in non-cervical puncture surgeries, a fixed-size head cover is often used to cover the patient's head. The head cover consists of a base plate and multiple arc-shaped support rods fixed to the base plate. The patient's head is placed on the base plate between the base plate and the support rods, and then a sterile treatment drape is laid on the support rods. However, when performing cervical puncture surgery, the head cover is removed because the support rods would obstruct the surgery.
[0004] However, since the head size of patients undergoing non-cervical puncture surgery varies, it is difficult to make a fixed-size head cover adaptable to the head size. Furthermore, the head cover is difficult to use during cervical puncture surgery, which means that sterile treatment towels can only be directly placed on the patient's face, causing the patient to feel stuffy and affecting the surgical process. Utility Model Content
[0005] In view of the shortcomings of the above-mentioned related technologies, this application provides a special support head cover for interventional procedures.
[0006] The technical solution for a special support headgear for interventional procedures provided in this application is as follows:
[0007] A special support headgear for interventional procedures, characterized in that it comprises:
[0008] The base is used to support the patient's head.
[0009] The side plate is vertically fixed to the base;
[0010] A lifting plate is slidably disposed on the side plate in a direction that is closer to or farther from the base;
[0011] The cover plate is rotatably mounted on the side of the lifting plate away from the base.
[0012] Preferably, the cover plate includes a first folding plate, a second folding plate, a first locking component for fixing the cover plate in a folded state, and a second locking component for fixing the cover plate in an extended state. The first folding plate is rotatably connected to the side of the lifting plate away from the base on one side, and rotatably connected to the second folding plate on the other side.
[0013] Preferably, the first locking assembly includes two magnetic attractors respectively fixed to the first folding plate and the second folding plate, wherein when the first folding plate and the second folding plate are in a folded state, the opposite magnetic poles of the two magnetic attractors are in contact.
[0014] Preferably, the second folding plate is rotatably connected to the side of the first folding plate, and a locking groove is provided thereon. The second locking assembly includes a locking rod that is slidably disposed on the first folding plate and an elastic member for driving the locking rod to move toward the second folding plate. When the first folding plate and the second folding plate are in the unfolded state, one end of the locking rod is located in the locking groove.
[0015] Preferably, the side plate is provided with a sliding groove, the length direction of the sliding groove is arranged perpendicular to the base, the lifting plate is fixed with a slide rail, the slide rail is slidably arranged in the sliding groove, and the side plate is provided with a locking bolt, the locking bolt is threaded through the side plate and abuts against the slide rail.
[0016] Preferably, the lifting plate has a clearance groove on the side away from the base, and an elastic pressure plate is provided in the clearance groove, with one end of the elastic pressure plate fixed to the bottom wall of the clearance groove.
[0017] Preferably, a limiting groove for accommodating the pipe is provided on the bottom wall of the relief groove, and the elastic pressure plate covers the limiting groove.
[0018] Preferably, the lifting plate, the first folding plate, and the second folding plate are all provided with ventilation openings in the direction of their surfaces.
[0019] Preferably, the base has multiple ventilation holes.
[0020] Preferably, an elastic head pad is fixed on the base.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. When performing non-transcervical puncture surgery, the cover plate is rotated relative to the lifting plate until it is perpendicular to the lifting plate. Then, the lifting plate is adjusted to rise and fall on the side plate to accommodate the patient's head size. A sterile treatment drape is then placed on the cover plate. When performing transcervical puncture surgery, the cover plate is rotated to be parallel to the lifting plate, making it easier to place a sterile treatment drape on top of the lifting plate. The lifting plate is then adjusted to rise and fall on the side plate to reduce the coverage area of the sterile treatment drape on the patient's face. The interventional procedure-specific support head cover of this application adapts to various situations of non-transcervical puncture surgery and transcervical puncture surgery by raising and lowering the lifting plate and rotating the cover plate, thus improving its versatility.
[0023] 2. During transcervical puncture surgery, the cover plate is rotated to a position parallel to the lifting plate to avoid obstructing the surgical operation, while still allowing the sterile treatment drape to be placed on top of the lifting plate, thereby reducing obstruction to the patient and improving the patient's surgical experience.
[0024] 3. This application uses a spatial structure consisting of a base, side panels, lifting plates, and a cover plate, in conjunction with a sterile treatment towel, to protect the patient's head and improve the efficiency of interventional procedures. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0032] This application discloses a special support headgear for interventional procedures. (Refer to...) Figure 1A special support headgear for interventional procedures includes a base 1 for supporting the patient's head, a side plate 2 vertically fixed to the base 1, a lifting plate 3 slidably disposed on the side plate 2 in a direction toward or away from the base 1, and a cover plate 4 rotatably disposed on the side of the lifting plate 3 away from the base 1. Specifically, the side plate 2 is fixed to one end of the base 1 along its length. Furthermore, to improve the comfort of the patient's head placed on the base 1, an elastic head cushion 15 is also fixed to the base 1. The elastic head cushion 15 is made of sponge material, taking into account both elasticity and breathability.
[0033] Specifically, to raise and lower cover plate 4, refer to... Figure 1 and Figure 2 The side plate 2 has two sliding grooves 16, which are arranged along the width of the base 1 and perpendicular to the length of the base 1. Two slide rails 6 are fixed to the lifting plate 3, sliding within the sliding grooves 16. A locking bolt 7 is provided on the side plate 2, threaded through the side plate 2 and abutting against the slide rails 6. To facilitate operation of the locking bolt 7, a handle 8 is fixed to the end of the locking bolt 7 outside the sliding groove 16. When the height of the cover plate 4 needs to be controlled, the locking bolt 7 is rotated using the handle 8 until it no longer abuts against the slide rail 6. Then, the height of the lifting plate 3 is adjusted according to the patient's head size. Finally, the locking bolt 7 is rotated again using the handle 8 until it abuts against the slide rail 6, at which point the lifting plate 3 and the side plate 2 are relatively fixed.
[0034] To store cover plate 4, refer to Figure 1 and Figure 2 The cover plate 4 includes a first folding plate 41, a second folding plate 42, a first locking assembly 43 for fixing the cover plate 4 in a folded state, and a second locking assembly 44 for fixing the cover plate 4 in an extended state. The first folding plate 41 is rotatably connected to the side of the lifting plate 3 away from the base 1 on one side and to the second folding plate 42 on the other side. Specifically, to avoid interference between the first folding plate 41 and the lifting plate 3 during rotation, an extension block 10 is fixed to the side of the lifting plate 3 away from the side plate 2. An avoidance groove 11 is provided on the first folding plate 41, and the extension block 10 is located in the avoidance groove 11. The first folding plate 41 is rotatably connected to the extension block 10 through a hinge 12. The first folding plate 41 is rotatably connected to the second folding plate 42 through the hinge 12. To further reduce the space occupied during folding, when both the first folding plate 41 and the second folding plate 42 are perpendicular to the base 1, the hinge 12 is located below the first folding plate 41 and the second folding plate 42 (not shown in the figure). Furthermore, to improve the overall breathability and weight of the headgear, ventilation openings 9 are provided on the lifting plate 3, side plate 2, first folding plate 41 and second folding plate 42 in the direction of the plate surface.
[0035] Specifically, to fix the first folding plate 41 and the second folding plate 42 in the folded state, refer to... Figure 1The first locking assembly 43 includes two magnetic attractors 431 respectively fixed on the first folding plate 41 and the second folding plate 42. When the first folding plate 41 and the second folding plate 42 are in a folded state, the surfaces of the first folding plate 41 and the second folding plate 42 are in contact with each other, and the opposite magnetic poles of the two magnetic attractors 431 are in contact. Specifically, in this application, the magnetic attractor 431 is a rectangular magnet. In other embodiments, the magnetic attractor 431 can also be a circular magnet or a ring magnet.
[0036] To fix the first folding plate 41 and the second folding plate 42 in the unfolded state, refer to Figure 2 and Figure 3 The second folding plate 42 is rotatably connected to the side of the first folding plate 41, and a locking groove 17 is provided thereon. The second locking assembly 44 includes a locking rod 441 slidably disposed on the first folding plate 41 and an elastic element 442 for driving the locking rod 441 to move toward the second folding plate 42. Specifically, in this embodiment, the elastic element 442 is a tension spring. One end of the locking rod 441 is located in the vent 9 of the first folding plate 41 and is coaxially fixed with an operating piece 18. The tension spring is sleeved on the locking rod 441, with one end fixedly connected to the first folding plate 41 and the other end fixedly connected to the operating piece 18. When the first folding plate 41 and the second folding plate 42 are in the unfolded state, the tension spring drives the locking rod 441 to move toward the second folding plate 42, and the locking rod 441 passes through the first folding plate 41 and moves into the locking groove 17 of the second folding plate 42.
[0037] When performing non-transcervical puncture surgery, the cover plate 4 is rotated relative to the lifting plate 3 until it is perpendicular to the lifting plate 3. At this time, the first folding plate 41 and the second folding plate 42 are selected to be in the unfolded or folded state based on the length of the patient's head along the length direction of the base 1. Then, the lifting plate 3 is adjusted to rise and fall on the side plate 2 to accommodate the length of the patient's head along the direction perpendicular to the base 1. A sterile treatment towel is then draped over the cover plate 4. When performing transcervical puncture surgery, the cover plate 4 is rotated to be parallel to the lifting plate 3. At this time, the first folding plate 41 and the second folding plate 42 are in the folded state. A sterile treatment towel is draped over the top of the lifting plate 3. The lifting plate 3 is adjusted to rise and fall on the side plate 2 to reduce the coverage area of the sterile treatment towel on the patient's face.
[0038] Furthermore, during neck puncture surgery, to facilitate fixation of the endotracheal tube and reduce the degree of tube displacement, refer to... Figure 1Both the lifting plate 3 and the first folding plate 41 have clearance grooves 13 on the side away from the base 1. A limiting groove 14 for accommodating the pipe is formed on the inner bottom wall of the clearance groove 13. An elastic pressure plate 5 is provided in the clearance groove 13, with one end of the elastic pressure plate 5 fixed to the inner bottom wall of the clearance groove 13 and covering the limiting groove 14. Specifically, the elastic pressure plate 5 is integrally formed from a positioning part 51, a pressing part 52, and an operating part 53. The positioning part 51 is a straight plate fixed to the inner bottom wall of the clearance groove 13. The pressing part 52 is a semi-circular ring with its inner arc surface facing the limiting groove 14. The operating part 53 is an arc-shaped plate with its outer arc surface facing the inner bottom wall of the clearance groove 13, thus facilitating the user to move the elastic pressure plate 5 away from the limiting groove 14. When performing a neck puncture, the user drives the elastic pressure plate 5 to move away from the limiting groove 14, and then inserts the tube between the limiting groove 14 and the inner arc surface of the clamping part 52. At this time, the elastic pressure plate 5 restricts the tube between the inner wall of the limiting groove 14 and the inner arc surface of the clamping part 52 under its elastic action, thereby increasing the difficulty of tube displacement during the operation.
[0039] Reference Figure 4 To further improve the breathability of the hood, multiple ventilation holes 19 are provided on the base 1. The multiple ventilation holes 19 are distributed in an array along the surface of the base 1.
[0040] The implementation principle of a special support head cover for interventional procedures in this application embodiment is as follows: When performing non-transcervical puncture surgery, the cover plate 4 is rotated relative to the lifting plate 3 to a state perpendicular to the lifting plate 3. At this time, the first folding plate 41 and the second folding plate 42 are selected to be in an unfolded state or a folded state according to the length dimension of the patient's head along the length direction of the base 1. Then, the lifting plate 3 is adjusted to rise and fall on the side plate 2 to adapt to the length dimension of the patient's head along the direction perpendicular to the base 1, and a sterile treatment towel is placed on the cover plate 4. When performing a transcervical puncture, the cover plate 4 is rotated to be parallel to the lifting plate 3. At this time, the first folding plate 41 and the second folding plate 42 are folded. The sterile treatment towel is placed on top of the lifting plate 3. The lifting plate 3 is adjusted to rise and fall on the side plate 2 to reduce the coverage of the sterile treatment towel on the patient's face. The user drives the elastic pressure plate 5 to move away from the limiting groove 14. Then the tube is inserted between the limiting groove 14 and the inner arc surface of the pressing part 52. At this time, the elastic pressure plate 5 restricts the tube between the inner wall of the limiting groove 14 and the inner arc surface of the pressing part 52 under its elastic action.
