Description

Technical Field

[0001] The present application relates to the field of medical instruments, and more specifically, to a neurosurgery head fixation and nursing device. Background Art

[0002] Neurosurgery is mainly concerned with diseases of the brain, spinal cord and other nervous systems caused by trauma. During neurosurgery, the patient's head needs to be fixed to facilitate stable surgery and reduce surgical risks. Existing methods of fixing patients are mostly limited by nursing pillows or straps. All of the above methods have a range of shaking and poor stability. The patent document with the prior art publication number CN213851122U provides a head fixation device for neurosurgery nursing. The device places the patient's head on the top of the head support plate, and uses the pressure of the patient's head to drive the support slide bar to slide downward, so that the two sets of connecting pull plates can drive the two sets of L-shaped support plates to slide in the direction close to the patient's head, so that the head splints on both sides can automatically clamp the two sides of the patient's head, thereby fixing the patient's head, and the fixing method is relatively convenient.

[0003] 5 With respect to the above-mentioned related technologies, the inventor believes that the device relies on the weight of the patient's head to achieve adaptive fixation. However, the patient is in an anesthetized sleeping state during the operation, so the head splint will exert a large pressure on the patient's head for a long time, and the safety and practicality are low. Therefore, we propose a neurosurgery head fixation nursing device. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, the present application provides a neurosurgery head fixation nursing device, which adopts the following technical solutions:

[0005] A neurosurgery head fixing nursing device comprises a base, a headrest is fixedly mounted on the base, sliding seats are arranged on both sides of the headrest, limit pads are connected to the sliding seats, a cross bar is elastically connected inside the base, two sliding sleeves are slidably engaged on the cross bar, the sliding sleeves are fixedly connected to the sliding seats, and two tooth plates A are fixedly connected to the cross bar in a symmetrical structure, a tooth plate B is fixedly connected inside the sliding sleeve, and the tooth plate A and the tooth plate B are snap-fitted.

[0006] By adopting the above technical solution, after the patient's head is resting on the headrest, the two slides are pushed to one side of the headrest, so that the two limit pads are respectively limited by the two sides of the patient's head, and the slide drives the sliding sleeve to slide on the cross bar when sliding, and the tooth plate B abuts against the tooth plate A to make the cross bar move downward. When the sliding sleeve stops sliding, the cross bar is reset to make the tooth plate A and the tooth plate B engage, and the sliding sleeve is limited, thereby realizing rapid and effective fixation of the patient's head.

[0007] Optionally, a screw rod is rotatably connected to the sliding seat, a slider is threadedly connected to the screw rod, the slider is slidably connected to the sliding seat, and one end of the slider passes through the sliding seat and is rotatably connected to a limit pad.

[0008] By adopting the above technical solution, the height of the limit pad can be adjusted by rotating the screw slider to perform lifting and sliding. At the same time, the limit pad can be rotated so that it can be adjusted and adapted according to different patients.

[0009] Optionally, the cross bar is slidably connected to the base, both ends of the cross bar are elastically connected to the base via a spring A, and both ends of the cross bar pass through the base and are fixedly connected to a shift block.

[0010] By adopting the above technical solution, spring A drives the cross bar to move upward, so that tooth plate A is driven to abut against tooth plate B. When the shift block is pressed downward to drive the cross bar to descend, tooth plate A cancels the abutment with tooth plate B, and the sliding sleeve can slide freely.

[0011] Optionally, a spring B is elastically connected between the sliding sleeve and the base.

[0012] By adopting the above technical solution, when the two sliding sleeves move towards each other, the spring B stretches and accumulates force. After the cross bar drops, the spring B contracts and resets to drive the sliding sleeve to slide in the opposite direction, so that the limit pad automatically cancels the limit on the head.

[0013] Optionally, a connecting plate is fixedly connected to the bottom of the base, a support seat is slidably connected to the connecting plate, an arc-shaped hole is opened on one side of the support seat, a limiting bolt is arranged in the arc-shaped hole, and the limiting bolt is threadedly connected to the connecting plate.

[0014] By adopting the above technical solution, the connecting plate can slide in the support seat, thereby adjusting the inclination angle of the base, so that the orientation of the patient's head can be adjusted. After rotating the limit bolt to abut against the support seat, the sliding of the connecting plate can be limited.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. By manually pushing the slide, the limit pad can be driven to effectively and comfortably abut the patient's head. When tooth plate A abuts tooth plate B, the sliding of the slide can be limited to achieve automatic locking. The limit pad can be adjusted in height and angle on the slide, so that it can be adjusted and adapted according to different patients, further improving the comfort of use.

[0017] 2. By sliding the connecting plate in the support seat, the inclination angle of the base can be adjusted, thereby adjusting the position of the patient's head, making it easier for doctors to perform surgical care operations and improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] Reference Figure 1-4 The present application includes a base 1, on which a headrest 2 is fixedly installed, slide seats 3 are arranged on both sides of the headrest 2, and limited pads 6 are connected to the slide seats 3. A cross bar 7 is elastically connected inside the base 1, and two sliding sleeves 10 are slidably matched on the cross bar 7. The sliding sleeve 10 is connected and fixed to the slide seat 3, and two tooth plates A11 are fixedly connected to the cross bar 7 in a symmetrical structure. A tooth plate B12 is fixedly connected inside the sliding sleeve 10, and the tooth plate A11 is engaged with the tooth plate B12. After the patient's head is resting on the headrest 2, the two slide seats 3 are pushed to one side of the headrest 2, so that the two limiting pads 6 are respectively limited with both sides of the patient's head, and when the slide seat 3 slides, the sliding sleeve 10 is driven to slide on the cross bar 7, and the tooth plate B12 abuts against the tooth plate A11 to make the cross bar 7 move downward. When the sliding sleeve 10 stops sliding, the cross bar 7 is reset to make the tooth plate A11 engage with the tooth plate B12, and the sliding sleeve 10 is slidably limited, thereby realizing rapid and effective fixation of the patient's head.

[0025] Reference Figure 2 A screw rod 4 is rotatably connected to the slide seat 3, and a slider 5 is threadedly connected to the screw 4. The slider 5 is slidably connected to the slide seat 3, and one end of the slider 5 passes through the slide seat 3 and is rotatably connected to the limiting pad 6. The screw 4 and the slider 5 are rotated to lift and slide, and the height of the limiting pad 6 can be adjusted. At the same time, the limiting pad 6 can be rotated so that it can be adjusted and adapted according to different patients.

[0026] Reference Figure 3The cross bar 7 is slidably connected to the base 1, and both ends of the cross bar 7 are elastically connected to the base 1 through springs A8, and both ends of the cross bar 7 pass through the base 1 and are fixedly connected with shift blocks 9. The spring A8 drives the cross bar 7 to move upward, so that the tooth plate A11 is driven to abut against the tooth plate B12. When the shift block 9 is pressed downward to drive the cross bar 7 to descend, the tooth plate A11 cancels the abutment with the tooth plate B12, and the sliding sleeve 10 can slide freely.

[0027] Reference Figure 4 The teeth of tooth plate A11 and tooth plate B12 are both right triangle structures. When the sliding sleeve 10 slides to the right, the inclined surface of tooth plate B12 abuts against the inclined surface of tooth plate A11, thereby driving the cross bar 7 to move downward. When the sliding sleeve 10 stops sliding, the spring A8 drives the cross bar 7 to rise, so that the tooth plate A11 abuts against the tooth plate B12 to prevent the sliding sleeve 10 from sliding in the opposite direction.

[0028] Reference Figure 3 A spring B13 is elastically connected between the sliding sleeve 10 and the base 1. When the two sliding sleeves 10 move toward each other, the spring B13 stretches and accumulates force. After the cross bar 7 drops, the spring B13 contracts and resets to drive the sliding sleeve 10 to slide in the opposite direction, so that the limit pad 6 automatically cancels the limit on the head.

[0029] Reference Figure 1 A connecting plate 14 is fixedly connected to the bottom of the base 1, and a support seat 15 is slidably connected to the connecting plate 14. An arc-shaped hole is opened on one side of the support seat 15, and a limiting bolt 16 is arranged in the arc-shaped hole. The limiting bolt 16 is threadedly connected to the connecting plate 14, and the connecting plate 14 can slide in the support seat 15, so as to adjust the inclination angle of the base 1, so that the orientation of the patient's head can be adjusted. After the limiting bolt 16 is rotated to abut against the support seat 15, the sliding of the connecting plate 14 can be limited.

[0030] Reference Figure 1 A mounting plate is fixedly connected to one side of the support seat 15. After the mounting plate is fixedly connected to the bottom of one end of the bed, the top surface of the base 1 can be flush with the top surface of the bed.

[0031] The implementation principle of a neurosurgery head fixation care device in an embodiment of the present application is as follows: after the patient's head is resting on the headrest 2, the screw rod 4 is rotated to make the slider 5 rise and fall, the limit pad 6 is adjusted to a suitable height, and the limit pad 6 can be rotated, and then the slide seat 3 is pushed to one side of the headrest 2, so that the limit pad 6 can effectively and comfortably clamp the patient's head, and the spring A8 drives the cross bar 7 to rise, so that the tooth plate A11 abuts against the tooth plate B12 to prevent the sliding sleeve 10 from sliding in the opposite direction, thereby facilitating the doctor's head surgery care for the patient.
