Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a neck support device for ear, nose, throat and head and neck surgery. Background Technology

[0002] Head and neck surgery is an extension of otolaryngology, gradually developing to meet the clinical diagnosis, treatment, and research needs of malignant tumors related to the head and neck and otolaryngology. Head and neck surgical diseases can be classified into many types based on their onset time, location, and nature, broadly including: congenital diseases and malformations of the neck, inflammatory diseases of the neck, vascular diseases of the neck, thyroid and parathyroid diseases, submandibular gland diseases, parotid gland diseases, neck tumors, neck masses, etc. Neck support devices are often indispensable in the diagnosis and treatment of head and neck surgical diseases.

[0003] Existing neck support devices are usually designed to adjust the support height according to the differences in the patient's physique, so as to obtain an appropriate position that can fully expose the surgical field. However, as the neck support position is continuously raised, the angle between the patient's head and shoulders and the neck will gradually decrease, which can easily cause the shoulders and head to be suspended in the air. Prolonged support can easily cause discomfort to the patient. Summary of the Invention

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1, referring to Figure 1-5 As shown, this embodiment provides a neck support device for ear, nose, throat and head and neck surgery, including:

[0032] The frame includes a bottom frame 1, with side plates 2 fixedly connected to the two side walls of the bottom frame 1, and drag pads 3 fixedly connected between the outer edges of the two side plates 2 and the two ends of the bottom frame 1.

[0033] The neck support mechanism includes a lifting component, which is fixedly installed in the base frame 1. A neck support plate 4 is drivenly connected to the lifting component, and the neck support plate 4 abuts against the inner surface of the padding 3.

[0034] The side support mechanism includes two adjustment components, both of which are connected to the lifting component. The adjustment components are connected to the side support plate 5. The two side support plates 5 are symmetrically located on both sides of the neck support plate 4. The side support plates 5 abut against the inner surface of the pad 3.

[0035] After the patient's neck rests on the surface of the pad 3, the lifting component drives the neck support plate 4 to rise and fall vertically, thus adjusting the support position of the patient's neck. The lifting component drives the two adjustment components to move synchronously, so that the two side support plates 5 flip away from the neck support plate 4. The sliding trajectory of the side support plates 5 is arc-shaped, so that when adjusting the support position of the patient's neck, the two side support plates 5 simultaneously support the patient's head and shoulders, so that the patient's head and shoulders can always be reliably supported.

[0036] Further optimization of the scheme: the lifting assembly includes two transmission rods 6, which are rotatably connected between the two inner end walls of the bottom frame 1. Threaded sections 7 are symmetrically opened on the transmission rods 6, with the two threaded sections 7 in opposite directions. A sliding block 8 is threaded onto the threaded section 7, and a first hinge seat 9 is fixedly connected to the sliding block 8. A support rod 10 is hinged to the first hinge seat 9, and a second hinge seat 11 is hinged to the end of the support rod 10 away from the first hinge seat 9. The second hinge seat 11 is fixedly connected to the bottom surface of the neck support plate 4.

[0037] By rotating the two transmission rods 6 synchronously, the threaded transmission through the threaded section 7 can cause the four sliding blocks 8 to slide in pairs relative to each other or away from each other, thereby realizing the lifting and lowering of the neck support plate 4 through the first hinge seat 9, the support rod 10 and the second hinge seat 11.

[0038] To further optimize the design, limit grooves 12 are respectively opened on the opposite surfaces of the two side plates 2, and limit blocks 13 are slidably connected in the limit grooves 12. The two limit blocks 13 are respectively fixed to both ends of the neck support plate 4.

[0039] The neck support plate 4 can be guided and limited by the limiting block 13 and the limiting slide 12, so as to facilitate its lifting and lowering effect.

[0040] Further optimization of the scheme: the adjustment component includes a shaft 14, which is rotatably connected between the two inner side walls of the bottom frame 1 and is located below the transmission rod 6. The two side support plates 5 are respectively fixed to the two shafts 14. Two main gears 15 are rotatably connected to the shafts 14. The four main gears 15 correspond to and are connected to the four sliding blocks 8 respectively.

[0041] In a further optimized design, a rack plate 16 is fixedly connected to the bottom surface of the sliding block 8. The rack plate 16 is meshed with a secondary gear 17. The secondary gear 17 is rotatably connected to the inner side wall of the bottom frame 1 via a support rod 18. The secondary gear 17 is meshed with the main gear 15.

[0042] By sliding the sliding block 8, the rack plate 16 is driven to slide synchronously, thereby driving the secondary gear 17 to rotate. The rotation of the secondary gear 17 drives the main gear 15 to rotate, thereby changing the rotation direction of the main gear 15, which in turn drives the shaft 14 to rotate. This achieves the effect of the side support plate 5 moving away from the neck support plate 4 when the neck support plate 4 is lifted.

[0043] In a further optimized design, a connecting rod 19 is fixedly connected to the side wall of the shaft 14, and a connecting plate 20 is fixedly connected to the end of the connecting rod 19 away from the shaft 14. The two side support plates 5 correspond one-to-one with the two connecting plates 20, and several first spring extension rods 21 are fixedly connected between the side support plates 5 and the connecting plates 20.

[0044] When the shaft 14 rotates, the side support plate 5 can be moved synchronously through the connecting rod 19, the first spring extension rod 21 and the connecting plate 20. The first spring extension rods 21 can generate a certain amount of movement between the side support plate 5 and the connecting plate 20 and maintain a pre-tight state, thereby avoiding excessive squeezing force on the patient's head or shoulders, adapting to the displacement changes of the patient's head or shoulders, improving the support effect and the patient's comfort.

[0045] In a further optimized design, a drive rod 22 is rotatably connected between the two inner sidewalls of the bottom frame 1. The drive rod 22 is located at either end of the two transmission rods 6. Two first bevel gears 23 are fixedly sleeved on the sidewall of the drive rod 22. The first bevel gears 23 are meshed with a second bevel gear 24. The two second bevel gears 24 are fixedly sleeved on the sidewalls of the two transmission rods 6, and one end of the drive rod 22 extends out of the bottom frame 1 and is fixedly connected to a drive head 25.

[0046] By rotating the drive head 25, the drive rod 22 is driven to rotate, which in turn drives the first bevel gear 23 to rotate. The first bevel gear 23 then drives the second bevel gear 24, which meshes with it, to rotate, thereby achieving synchronous rotation of the two transmission rods 6.

[0047] In a further optimized design, a first toothed ring 26 is fixedly sleeved at any end of the shaft 14. The first toothed ring 26 is detachably connected to a second toothed ring 27. Two guide rods 28 are fixedly connected to the end face of the second toothed ring 27 away from the first toothed ring 26. The end of the guide rod 28 away from the second toothed ring 27 extends out of the bottom frame 1, and a guide plate 29 is fixedly connected between the extended ends of the two guide rods 28. A threaded sleeve 30 is rotatably connected to the guide plate 29. A screw 31 is threadedly connected to the threaded sleeve 30, and the screw 31 is fixedly connected to the outer wall of the bottom frame 1.

[0048] When adjustment is needed, the threaded sleeve 30 is rotated to displace the screw 31, thereby causing the guide plate 29 to move synchronously. The guide plate 29 then causes the two guide rods 28 and the second toothed ring 27 to disengage from the first toothed ring 26, thereby releasing the restriction on the shaft 14. Conversely, when the first toothed ring 26 and the second toothed ring 27 are engaged, the shaft 14 can be prevented from rotating, thus improving the stability of the side support plate 5.

[0049] The design was further optimized by adding several ventilation holes 32 to the pad 3.

[0050] The comfort of the ring neck is improved by setting several ventilation holes 32 to prevent sweat accumulation.

[0051] The design was further optimized so that the contact surfaces of the neck support plate 4 and the side support plate 5 with the pad 3 are all arc-shaped.

[0052] The curved shape can improve the support comfort for the corresponding patient, and the neck support plate 4 and the side support plate 5 are preferably made of flexible materials with a certain support force.

[0053] Example 2, refer to Figure 6-7 A vertical plate 33 is fixedly connected to either end of the two side plates 2. A slide rod 34 is fixedly connected between the two vertical plates 33. Two pull blocks 35 are slidably connected to the slide rod 34. A pull plate 36 is fixedly connected to the bottom surface of the pull block 35. A fixing plate 38 is fixedly connected to the opposite surface of the two pull plates 36 through a second spring telescopic rod 37. One end of a pull rod 39 is fixedly connected to the top surface of the pull block 35 near the threaded sleeve 30. The other end of the pull rod 39 is rotatably connected to the threaded sleeve 30 through a bearing. A guide wheel 40 is installed at the top of the vertical plate 33 away from the pull rod 39. A pull rope 41 is wound around the guide wheel 40. One end of the pull rope 41 is fixedly connected to the pull rod 39, and the other end is fixedly connected to the pull block 35 away from the pull rod 39. A compression spring 42 is fixedly connected between the pull block 35 away from the pull rod 39 and the vertical plate 33 near it. The compression spring 42 is sleeved on the slide rod 34.

[0054] Thus, when the threaded sleeve 30 is rotated outward, the pull rod 39 can be moved synchronously, thereby causing the two pull blocks 35 to move in opposite directions by the pull rope 41 and the guide wheel 40, thereby increasing the distance between the two fixing plates 38, making it easier to insert the patient's head. Conversely, after adjusting the position of the neck, head, and shoulders, the threaded sleeve 30 needs to be reset to lock the shaft 14. At the same time as the threaded sleeve 30 resets, the pull rod 39 pushes the pull block 35 fixed to it to reset, thereby compressing the spring 42 to push the pull block 35 fixed to it to reset, thereby causing the two pull blocks 35 to slide towards each other, thereby clamping and fixing the two fixing plates 38 to both sides of the patient's head. Moreover, by setting the compression spring 42, the clamping force can be avoided to be too tight, improving comfort.
