Description

Technical Field

[0001] The present application relates to the technical field of fixation devices, and more particularly to a preoperative fixation device with small-area contact. Background Art

[0002] Before performing surgery on a patient, the patient's head needs to be fixed to the operating table to ensure that unnecessary movement of the patient's head is avoided during the surgery, thereby reducing the failure rate of the surgery.

[0003] The document with prior art publication number CN216455901U provides a surgical head fixation device. During surgery, the patient's head is placed on the headrest pad, and the left positioning plate and the right positioning plate are respectively located on both sides of the head. The positioning plates are fixed using a pressing column, and then a first positioning strap is used to position the patient's forehead, and a second positioning strap is used to position the patient's mandible. In this way, the patient's head can be positioned, which is convenient for subsequent surgery and simple and convenient.

[0004] The document with prior art publication number CN218528728U provides a head fixation device. By turning the handle through a bidirectional threaded rod, the bidirectional threaded rod is driven to rotate, which drives the fixed block to move. Under the action of the opposite threads at both ends of the bidirectional threaded rod, the two first sliders move in opposite directions, making it easy for people to accurately adjust the size of the head clamping space according to the size of the patient's head.

[0005] Although this device has many beneficial effects, the following problems still exist: when fixing the patient's head before surgery, the contact area with the patient's head is large, which takes up a large space when performing surgery on the patient's head, and easily affects the operating space of medical staff during surgery. In view of this, we propose a preoperative fixation device with a small contact area. Utility Model Content

[0011] Optionally, the fixing mechanism further specifically includes: a pad adhered to the bottom of the positioning plate by adhesive, which ensures friction with the patient's forehead while preventing the patient's forehead from being clamped and damaged.

[0012] By adopting the above technical solution, the backing plate is bonded to the positioning plate, thereby facilitating replacement of the backing plate and preventing cross infection.

[0013] Optionally, the fixing mechanism further specifically includes: rotating rods are fixedly connected to both sides of the threaded ring, and the rotating rods are rotatably connected to the fixing plate, thereby facilitating adjustment of the angle between the threaded ring and the first threaded rod.

[0014] Optionally, one end of one of the rotating rods is fixedly connected to a gear, and one side of the fixed plate is slidably connected to a toothed plate, so that when the toothed plate moves, the rotating rod and the threaded ring can be driven to rotate through the gear.

[0015] By adopting the above technical solution and setting a rotating rod, the gear can be driven to rotate when the tooth plate moves, the rotation of the gear can drive the rotating rod to rotate, and the rotation of the rotating rod can drive the threaded ring and the first threaded rod to rotate, thereby facilitating the positioning of both sides of the patient's forehead.

[0029] With reference to Figure 1 , the fixing mechanism 4 further comprises a positioning plate 43 fixedly connected to the bottom end of the first threaded rod 42, so as to prevent the bottom end of the first threaded rod 42 from directly contacting the forehead of the patient.

[0030] With reference to Figure 1 , the fixing mechanism 4 further comprises a pad 44 attached to the bottom of the positioning plate 43 by adhesive, and the pad 44 is made of medical silicone material and has a soft texture, so as to ensure the friction with the forehead of the patient and prevent the forehead of the patient from being damaged by clamping.

[0031] With reference to Figure 1 , the top end of the first threaded rod 42 is fixedly connected with a knob, and the outer side of the knob is provided with anti-slip patterns to prevent the medical staff from slipping.
