Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a head fixer for a fiberbronchoscope. Background Art

[0002] A fiberoptic bronchoscope (abbreviated as "fiberoptic bronchoscope") is a medical device used to examine and treat respiratory diseases. It consists of a soft, flexible, bendable tube with an optical fiber and a camera at one end that transmits images to the display screen used by the doctor. By operating the bronchoscope's joystick, the doctor can guide the bronchoscope into the patient's trachea and bronchi to observe the respiratory tract and detect lesions, foreign bodies or other abnormalities. The fiberoptic bronchoscope can also be used for therapeutic operations such as sampling, aspirating secretions, clearing the airway, and placing bronchial stents. It is widely used in medical fields such as respiratory medicine, respiratory surgery, and anesthesiology.

[0003] During bronchoscopy, since the patient is in a state of partial anesthesia and is stimulated by the bronchoscope, the patient's head will often shake during the examination, so a head fixator is needed to fix the patient's head. However, the existing head fixators have poor fixation effects and are not convenient for adjusting the angle of the patient's head, making it difficult to ensure the patency of the patient's airway, which may cause the patient to have difficulty breathing or airway compression, increasing the risk of the examination. At the same time, it will also affect the doctor's flexible adjustment of the examination position, which is not conducive to ensuring the accuracy of the examination and the comfort of the patient. Utility Model Content

[0004] The utility model aims to provide a head fixer for a fiberoptic bronchoscope which has good fixing effect and can adjust the elevation angle of the patient's head.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A head holder for a fiberoptic bronchoscope comprises a fixing plate, a support plate is rotatably mounted on the outer side of the fixing plate, a pillow seat is mounted on the upper surface of the support plate, and a first sponge pad is arranged on the upper surface of the pillow seat. A U-shaped frame is arranged on the upper surface of the support plate, a first threaded rod is vertically penetrated and threadedly connected to the inside of the cross bar of the U-shaped frame, a pressing plate is rotatably mounted on the end of the first threaded rod, and a second sponge pad is arranged on the lower surface of the pressing plate. Push rods are horizontally penetrated inside the vertical rods on both sides of the U-shaped frame, a clamping plate is mounted on the end of the push rod, a third sponge pad is arranged on the outer surface of the clamping plate, and a first locking bolt for fixing the push rod is arranged on the outer surface of the vertical rods on both sides of the U-shaped frame. A mounting plate is mounted on the lower surface of the fixing plate, and an adjustment mechanism capable of adjusting the angle of the support plate is arranged on the mounting plate.

[0007] It can be seen that after the patient's head is resting on the first sponge pad, the second sponge pad is driven to descend and pressed on the patient's forehead by rotating the first threaded rod to preliminarily fix the head, and then the push rods on both sides are pushed inward to drive the two third sponge pads to be pressed on both sides of the patient's head respectively, and the position of the push rods is fixed by the first locking bolt, thereby achieving the purpose of multi-directional fixation of the head with good fixation effect. Through the setting of the adjustment mechanism, the angle of the support plate can be adjusted, thereby achieving the purpose of adjusting the patient's head extension angle, so that the patient's airway can be smoothly opened and kept unobstructed, reducing the risk of examination, and also facilitating the doctor to flexibly adjust the examination position, which is conducive to ensuring the accuracy of the examination and the comfort of the patient, and is suitable for patients of different body shapes and ages.

[0008] Furthermore, the adjustment mechanism includes a second threaded rod rotatably connected to the inside of the mounting plate, sliding rods are connected to both sides of the second threaded rod inside the mounting plate, a driving block is commonly installed on the outer surface of the two sliding rods and the second threaded rod, the outer surface of the driving block is rotatably connected to a diagonal support rod, and the end of the diagonal support rod is rotatably connected to the lower surface of the support plate.

[0009] Since the two sliding rods limit the driving block, when the second threaded rod is rotated, the driving block can be driven to rise and fall vertically, so that the angle of the diagonal support rod changes, and the angle of the support plate is driven by the diagonal support rod to change, thereby achieving the purpose of adjusting the patient's head extension angle.

[0010] Furthermore, U-shaped slide plates are slidably installed on both sides of the support plate, and the bottoms of the vertical rods on both sides of the U-shaped frame are respectively installed on the upper surfaces of the two U-shaped slide plates, and the outer surfaces of the U-shaped slide plates are installed with second locking bolts.

[0011] After loosening the second locking bolt, the U-shaped slide plate can slide on the side of the support plate, thereby driving the position of the second sponge pad to change. When the position of the second sponge pad is adjusted, the second locking bolt is tightened to fix the U-shaped frame, so that the second sponge pad can be accurately pressed on the forehead of patients of different body shapes and ages for fixation.

[0012] Furthermore, both sides of the upper surface of the pressing plate are connected to limit rods, and the ends of the limit rods penetrate to the upper side of the U-shaped frame.

[0013] Through the limiting effect of the limiting rod on the pressure plate, when the first threaded rod is rotated, the second sponge pad can be driven to rise and fall vertically, thereby improving the portability of the operation.

[0014] Furthermore, U-shaped blocks are installed at both ends of the fixing plate, a third threaded rod passes through the interior of the U-shaped block and is threadedly connected, and a clamping block is installed at the end of the third threaded rod.

[0015] The U-shaped block is clamped on the side of the bed, and then the third threaded rod is rotated to drive the clamping block to be pressed on the bed. The fixator can be installed on the bed for use, and after use, it can be removed and stored, which improves the flexibility of use.

[0016] Furthermore, the first sponge pad and the pillow seat, the second sponge pad and the pressure plate, and the third sponge pad and the splint are all connected by Velcro.

[0017] Through the Velcro connection method, the first sponge pad, the second sponge pad and the third sponge pad can be easily removed for cleaning and disinfection, thereby avoiding cross infection and improving hygiene and safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The utility model is described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4As shown, a head holder for a fiberoptic bronchoscope comprises a fixing plate 100, a supporting plate 101 is rotatably mounted on the outer side of the fixing plate 100, a pillow seat 102 is mounted on the upper surface of the supporting plate 101, and a first sponge pad 103 is arranged on the upper surface of the pillow seat 102. A U-shaped frame 104 is arranged on the upper surface of the supporting plate 101, a first threaded rod 105 is vertically penetrated and threadedly connected to the inside of the cross bar of the U-shaped frame 104, a pressing plate 106 is rotatably mounted on the end of the first threaded rod 105, and a second sponge pad 107 is arranged on the lower surface of the pressing plate 106. Push rods 108 are horizontally penetrated inside the vertical rods on both sides of the U-shaped frame 104, a clamping plate 109 is mounted on the end of the push rod 108, a third sponge pad 110 is arranged on the outer surface of the clamping plate 109, and first locking bolts 111 for fixing the push rod 108 are arranged on the outer surfaces of the vertical rods on both sides of the U-shaped frame 104. A mounting plate 112 is mounted on the lower surface of the fixing plate 100 , and an adjustment mechanism 200 capable of adjusting the angle of the supporting plate 101 is disposed on the mounting plate 112 .

[0025] When in use, first rotate the first threaded rod 105 to drive the second sponge pad 107 to rise to a height, then the patient's head is rested on the first sponge pad 103, and the angle of the support plate 101 can be adjusted by the adjustment mechanism 200, and then the extension angle of the patient's head can be adjusted to ensure that the airway is opened smoothly, and then the first threaded rod 105 is rotated to drive the second sponge pad 107 to descend and press it against the patient's forehead, and then the push rods 108 on both sides are pushed inward in turn to drive the third sponge pad 110 to press against the side of the patient's head, and tighten the first locking bolt 111 to fix the position of the push rod 108. Since the threaded connection between the first threaded rod 105 and the U-shaped frame 104 is self-locking, the second sponge pad 107 can be stably pressed against the patient's forehead, so that the patient's head will not have a large shaking amplitude. Therefore, the effective fixation of the patient's head can be guaranteed only by the fixing effect of the first locking bolt 111, and during the examination, the doctor can still adjust the extension angle of the patient's head without affecting the fixing effect of the head.

[0026] Specifically, the adjustment mechanism 200 includes a second threaded rod 201 rotatably connected to the inside of the mounting plate 112, and the inside of the mounting plate 112 is connected to sliding rods 202 on both sides of the second threaded rod 201, and the two sliding rods 202 and the outer surface of the second threaded rod 201 are jointly installed with a driving block 203, and the outer surface of the driving block 203 is rotatably connected to a diagonal support rod 204, and the end of the diagonal support rod 204 is rotatably connected to the lower surface of the support plate 101. Since the two sliding rods 202 limit the driving block 203, when the second threaded rod 201 is rotated, the driving block 203 can be driven to rise and fall vertically, so that the angle of the diagonal support rod 204 changes, and the angle of the support plate 101 is driven by the diagonal support rod 204 to change, thereby achieving the purpose of adjusting the patient's head extension angle.

[0027] Specifically, U-shaped slides 300 are slidably installed on both sides of the support plate 101, and the bottoms of the vertical rods on both sides of the U-shaped frame 104 are respectively installed on the upper surfaces of the two U-shaped slides 300, and the outer surfaces of the U-shaped slides 300 are installed with second locking bolts 301. When the second locking bolts 301 are loosened, the U-shaped slide 300 can slide on the side of the support plate 101, thereby driving the position of the second sponge pad 107 to change. When the position of the second sponge pad 107 is adjusted, the second locking bolts 301 are tightened to fix the U-shaped frame 104, so that the second sponge pad 107 can be accurately pressed on the forehead of patients of different body shapes and ages for fixation.

[0028] Specifically, both sides of the upper surface of the pressure plate 106 are connected to the limiting rod 400, and the end of the limiting rod 400 passes through the upper side of the U-shaped frame 104. Through the limiting effect of the limiting rod 400 on the pressure plate 106, when the first threaded rod 105 is rotated, the second sponge pad 107 can be driven to rise and fall vertically, thereby improving the portability of the operation.

[0029] Specifically, U-shaped blocks 500 are installed at both ends of the fixing plate 100, and a third threaded rod 501 is passed through the interior of the U-shaped block 500 and is threadedly connected, and a clamping block 502 is installed at the end of the third threaded rod 501. The U-shaped block 500 is clamped on the side of the bed, and then the third threaded rod 501 is rotated to drive the clamping block 502 to be pressed against the bed. The fixer can be installed on the bed for use, and after use, it can be removed and stored, thereby improving the flexibility of use.

[0030] Specifically, the first sponge pad 103 and the pillow seat 102, the second sponge pad 107 and the pressure plate 106, and the third sponge pad 110 and the splint 109 are all connected by Velcro. The Velcro connection makes it easy to remove the first sponge pad 103, the second sponge pad 107 and the third sponge pad 110 for cleaning and disinfection, thereby avoiding cross infection and improving hygiene and safety.

[0031] The above is a detailed description of the utility model in combination with specific embodiments, and it cannot be determined that the specific implementation methods of the utility model are limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, making several equivalent substitutions or obvious modifications without departing from the concept of the utility model, and having the same performance or use, should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
