Description

A dressing changing device after nasal endoscopic surgery

Technical Field

The utility model relates to the technical field of nasal endoscopic surgery, in particular to a dressing changing device after nasal endoscopic surgery.

Background Art

Endoscopic sinus surgery is the use of a high-resolution, variable-angle Hopkins endoscope to perform sinus surgery, allowing surgery on the nasal cavity and sinuses, especially deep ones, to be performed under direct vision. It is also beneficial for cleaning lesions in some depressions and fissures, and can restore the ventilation and drainage functions of the sinuses. Under direct vision, the surgery causes less tissue damage, less bleeding, and a clear intraoperative field of view, which can avoid the occurrence of some complications and has become a routine nasal and sinus surgery.

The existing dressing changing device after endoscopic surgery needs to fix the patient's mandible during use, and then adjust the angle to change the dressing inside the patient's nasal cavity. However, the mandibular width of different patients is different. Conventional mandibular fixators cannot fix patients with too small or too wide mandibles. This will cause the patient's face to be unable to be accurately placed in the mandibular fixator for fixation. When the dressing is painful, the face is prone to shaking, making it inconvenient for medical staff to change the dressing.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-3, the utility model provides a technical solution:

A post-nasal endoscopic dressing device comprises a support seat 1, a support frame 2, a telescopic rod 3 and a support plate 4. The above structure is directly cited from the prior art and will not be described in detail here.

The outer wall of the support plate 4 is slidably connected with a lower jaw clamp plate 5, which is arranged in a C shape. The number of the lower jaw clamp plates 5 is set to two, one side of which is fixedly connected with a sleeve block 6, one side of the sleeve block 6 is provided with a slot 7, and the inner cavity of the slot 7 is arranged in a square shape, and one side of the other lower jaw clamp plate 5 is fixedly connected with an insert plate 8 adapted to the slot 7, and the lower jaw clamp plate 5 is fixed to the support plate 4 through a positioning assembly.

Specifically, as shown in Figure 3, the positioning assembly includes a support block 9, which is fixedly connected to one side of the support plate 4. A slide groove 10 is provided inside the support block 9. The width of the slide groove 10 is greater than the diameter of the threaded rod 12. The top of the support block 9 is slidably connected to the extrusion block 11, and the extrusion block 11 is arranged between the circular block 13 and the support block 9. The inside of the extrusion block 11 is slidably connected with the threaded rod 12, and the bottom of the threaded rod 12 is fixedly connected with a clamping block 19. The clamping block 19 is slidably connected to the inside of the slide groove 10. The clamping block 19 can make the threaded rod 12 stuck in the inside of the slide groove 10 and can only move horizontally but not rotate. The threaded rod 12 penetrates the inside of the extrusion block 11 and extends a part. The outer wall of the threaded rod 12 is threadedly connected with a circular block 13. The circular block 13 is arranged on the top of the extrusion block 11. When the circular block 13 rotates, the extrusion block 11 is pushed, and the extrusion block 11 is connected to the lower jaw clamping plate 5 through a sliding assembly.

Specifically, as shown in Figure 3, the sliding assembly includes a limit block 14, which is fixedly connected to one side of the extrusion block 11. The limit block 14 is in a T-shape, and a limit groove 15 is opened on one side of the mandibular clamping plate 5. The limit block 14 is slidably connected to the inner wall of the limit groove 15.

Specifically, as shown in FIG. 3 , a side ear 16 is fixedly connected to one side of the circular block 13 . The side ear 16 is arranged in an arc shape. The number of the side ears 16 is set to two and the two side ears 16 are arranged in a mirror-symmetrical manner with the circular block 13 as the center.

Specifically, as shown in Figure 1, one side of the support plate 4 is connected to a collecting plate 17 through a torsion spring shaft. The shape of the collecting plate 17 is set to be L-shaped, so that the collecting plate 17 can fit the mouth and be just below the patient's nostrils. A collecting groove 18 is provided on the top of the collecting plate 17. The collecting groove 18 can collect the medicine flowing out of the nasal cavity to prevent it from dripping onto the patient's clothes.

To sum up, when the dressing changing device provided in this embodiment is in use, the angle and length of the telescopic rod 3 are adjusted, and then the patient's mandible is placed on the support plate 4. Then the patient moves the two mandibular clamps 5 to insert the plug plate 8 into the slot 7 of the sleeve block 6. In this way, the distance between the two mandibular clamps 5 can be adjusted according to the mandibular width of the patient. After adjusting the mandibular clamps 5, the medical staff can rotate the circular block 13 through the side ears 16, and the circular block 13 will push the extrusion block 11 to move downward, and the extrusion block 11 will increase the friction between the support block 9, so that the extrusion block 11 cannot move. At the same time, the extrusion block 11 is connected to the mandibular clamp 5 through the limit block 14, so that the mandibular clamp 5 cannot move either. In this way, the mandibles of different patients can be fixed, so that the medical staff can change the dressing inside the patient's nasal cavity without the patient's face moving due to pain.

The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
