[0036] like Figures 1 to 3 As shown, an embodiment of the present invention provides a head support, including a bearing structure 1, wherein the bearing structure 1 includes a bearing body 11, an upper end of the bearing body 11 is fixedly connected to a connecting column 12, and the connecting column 12 and the bearing body 11 are integrally formed, a pressure cap 14 is threadedly connected to the top of the connecting column 12, a universal joint 13 is installed at the lower end of the bearing body 11, a head frame converter 8 is connected to the lower end of the bearing structure 1, the bearing body 11 is movably connected to the head frame converter 8 through the universal joint 13, the head frame converter 8 can make the head frame adapt to different operating tables, so as to facilitate fixing the patient's head to the operating table during surgery, wherein the head frame converter 8 is an existing mature technology.
[0037] like Figure 1 and Figure 2As shown, a first support arm 2 and two groups of second support arms 3 are respectively provided above the supporting structure 1, and a double-ear connecting structure 6 and a single-ear connecting structure 7 are connected to the upper end of the supporting structure 1 in sequence. The first support arm 2 is connected to the supporting structure 1 through the single-ear connecting structure 7, and the second support arm 3 is connected to the supporting structure 1 through the double-ear connecting structure 6. By rotating the pressure cover 14, the single-ear connecting structure 7 and the double-ear connecting structure 6 mounted on the connecting column 12 are pressed and fixed, thereby fixing the first support arm 2 and the second support arm 3 to prevent them from moving during use and affecting the support for the patient's head. The first support arm 2 and the two groups of second support arms 3 cooperate as a three-point head frame to support the patient's head, making it convenient for doctors to perform surgical operations on the patient's head.
[0038] A head bracket 15 is coaxially disposed above the binaural connection structure 6 and the monaural connection structure 7. The head bracket 15 comprises a support ring 151 and a mounting ring 152. The mounting ring 152 is a circular ring structure that fits over the connecting post 12. The mounting ring 152 is sleeved onto the connecting post 12 and secured by a gland 14. The support ring 151 is fixedly connected to the mounting ring 152 via multiple sets of curved support rods 153. The support rods 153 are curved metal sheets that provide support and cushioning for the support ring 151, further enhancing patient comfort. The support ring 151 conforms to the contours of the human face.
[0039] like Figures 3 to 5 As shown, the conical portion of the support ring 151 is provided with a suspended opening 155, and a chin support 154 is provided at both ends of the suspended opening 155. The chin support 154 is fixedly connected to the support ring 151. When the user places the head on the head support 15 in a prone position, the human face rests on the inside of the groove of the support ring 151 to support the head, and the neck is located at the suspended opening 155. The chin support 154 supports the user's mandible to avoid direct compression of the user's respiratory tract, thereby effectively improving the comfort of the head support 15. When the user places the head on the head support 15 in a supine position, the chin support 154 supports the back of the user's neck to provide support for the user's neck, effectively adapting to the human body and improving the comfort of the head support 15.
[0040] The support ring 151 has a C-shaped cross-section. A reinforcing protrusion 157 is provided on the inner wall of the support ring 151. A weakening groove 158 is provided on the outer wall of the support ring 151 at a position corresponding to the reinforcing protrusion 157. A positioning groove 156 is provided on the surface of the support ring 151 at a position opposite to the suspended opening 155. The structure of the positioning groove 156 is adapted to the structure of the back of the human head. The support ring 151 is made of a metal sheet and has a certain elastic deformation ability. The weakening groove 158 provided on the support ring 151 can guide the deformation position and direction of the support ring 151. The reinforcing protrusion 157 can prevent the support ring 151 from being damaged due to excessive deformation. When the human body adopts a prone position and places the head on the support ring 151, if the user's face is large, the support ring 151 will be squeezed and deformed to expand outward, and the deformation of the support ring 151 will also increase the fixing effect on the user's head. At the same time, the deformation ability of the support ring 151 can adapt to users with different face shapes, thereby increasing the scope of application. When the human body adopts a supine position, the back of the head is resting in the positioning groove 156, and the positioning groove 156 adapts to the head to increase the stability of the head.
[0041] like Figures 6 to 8 As shown, the double-ear connection structure 6 includes a connecting arm 1 61 and a connecting arm 2 62, which are rotatably connected to each other and are sleeved on the connecting column 12 and rotatably connected thereto. The ends of the two groups of second support arms 3 are respectively connected to the connecting arm 1 61 and the connecting arm 2 62 by fastening bolts 10. The side walls of the connecting arm 1 61 and the connecting arm 2 62 away from the connecting column 12 are both provided with threaded holes, and the side walls of the end of the rod of the fastening bolt 10 away from the nut are provided with threads that are compatible with the threaded holes on the connecting arm 1 61 and the connecting arm 2 62. The fastening bolt 10 passes through the second support arm 3 and the connecting arm 1 61 or the connecting arm 2 62 in sequence and is threadedly connected to the connecting arm 1 61 and the connecting arm 2 62.
[0042] The second support arm 3 is sleeved on the middle part of the fastening bolt 10. When the fastening bolt 10 is tightened to a certain extent, the friction force of the fastening bolt 10 and the connecting arm 1 61 or the connecting arm 2 62 on the second support arm 3 keeps it fixed. When the fastening bolt 10 is loosened to a certain extent, the second support arm 3 can rotate around the fastening bolt 10, which facilitates the adjustment of the angle of the second support arm 3.
[0043] The connecting arm 61 includes two sets of collars 611. When the double-ear connecting structure 6 is connected to the carrier 11, the collar 611 is sleeved on the connecting column 12 and can rotate around it. A connecting plate 613 is provided on one side of the collar 611. The two ends of the connecting plate 613 are respectively fixedly connected to the two sets of collars 611. An arm plate 615 is provided on the side of the connecting plate 613 away from the collar 611. The arm plate 615 is fixedly connected to the connecting plate 613.
[0044] The second connecting arm 62 includes two groups of second collars 621. When the double-ear connecting structure 6 is connected to the carrier 11, the second collar 621 is sleeved on the connecting column 12 and can rotate around it. A second connecting plate 623 is provided on one side of the second collar 621. The two ends of the second connecting plate 623 are respectively fixedly connected to the two groups of second collars 621. An arm plate 625 is provided on one side of the second connecting plate 623. The arm plate 625 is fixedly connected to the second connecting plate 623.
[0045] like Figure 7 and Figure 8 As shown, two groups of collars 611 are symmetrically arranged, and opposite sides of the two groups of collars 611 are provided with clamping edges 612, which are fixedly connected to collars 611. The clamping edges 612 are thin-walled annular structures that can undergo a certain elastic deformation. An embedded block 614 is provided on the side of the connecting plate 613, and the embedded block 614 is fixedly connected to the connecting plate 613.
[0046] The two sets of second collars 621 are symmetrically arranged. Opposite sides of the two sets of second collars 621 are provided with sunken grooves. The inner walls of the second collars 621 are provided with snap-in slots 622. These sunken grooves and snap-in slots 622 mate with the structure of the snap-in edge 612, allowing the snap-in edge 612 to enter the snap-in slots 622 and cooperate with the second collars 621. The sunken grooves are provided on the side of the second collars 621 facing the first collar 611 to facilitate the engagement of the snap-in edge 612. The end of the snap-in edge 612 is an arcuate ring that mates with the snap-in slots 622. This arcuate surface can change the direction of force, facilitating elastic deformation of the snap-in edge 612 during assembly and disassembly of the first and second collars 611, thus reducing assembly and disassembly difficulties. The side of the second connecting plate 623 is provided with an inserting slot 624 that mates with the structure of the inserting block 614. The inserting block 614 can be fitted with a rubber pad to provide a more secure fit between the inserting block 614 and the inserting slot 624.
[0047] When connecting arm 1 61 and connecting arm 2 62 cooperate, collar 2 621 is located inside the two sets of collar 1 611 and the clamping edge 612 is embedded in the clamping groove 622 for cooperative connection. When connecting arm 1 61 and connecting arm 2 62 are rotated to merge, connecting plate 1 613 and connecting plate 2 623 are spliced into one body through the embedding block 614 and the embedding groove 624. After the embedding block 614 enters the embedding groove 624, due to structural limitations, a certain external force is required to pull the two sets of connecting arm 1 61 and connecting arm 2 62 laterally to separate them, thereby preventing connecting arm 1 61 and connecting arm 2 62 from moving during combined use, affecting the fixation of the head.
[0048] like Figure 1 and Figure 9As shown, the single-ear connection structure 7 includes a ring three 71. When the single-ear connection structure 7 is connected to the carrier 11, the ring three 71 is sleeved on the connecting column 12 and can rotate around it. A connecting plate three 72 is fixedly connected to one side of the ring three 71. The first support arm 2 is connected to the connecting plate three 72 through a fastening bolt 10. The structure of the connecting plate three 72 is the same as the structure of the connecting plate one 613. The fastening bolt 10 passes through the first support arm 2 and the connecting plate three 72 in sequence and is threadedly connected to the connecting plate three 72. The first support arm 2 is sleeved on the middle part of the fastening bolt 10 and can rotate around it.
[0049] The first support arm 2 has an L-shaped structure, and a fixed head support 5 is provided at the end of the first support arm 2 away from the single-ear connection structure 7. The second support arm 3 has an L-shaped structure, and an adjustable head support 4 is provided at the end of the second support arm 3 away from the double-ear connection structure 6. The adjustable head support 4 has a Z-shaped structure, and is rotatably connected to the second support arm 3. One end of the adjustable head support 4 passes through the second support arm 3 and is threadedly connected to a fastening nut 9. By rotating and tightening the fastening nut 9, the adjustable head support 4 can be fixed to the second support arm 3. By loosening the fastening nut 9, the adjustable head support 4 can be rotated relative to the second support arm 3, making it easy to adjust the angle of the adjustable head support 4 to adapt it to different patients.
[0050] The working principle of the present invention is as follows: when the neurology department of the hospital performs a craniotomy on a patient, the medical staff first embeds the connecting arm 1 61 and the connecting arm 2 62 into the embedding groove 624 through the embedding block 614 and combines them together. At this time, the two groups of second adjustment arms connected to the connecting arm 1 61 and the connecting arm 2 62 are merged together, and the fastening bolts 10 connected to the first support arm 2 and the second support arm 3 are rotated respectively. After adjusting the angles of the first support arm 2 and the second support arm 3 to a suitable state, the fastening bolts 10 are reversed to fix the first support arm 2 to the single-ear connecting structure 7 and the second support arm 3 to the double-ear connecting structure 6. Then, the fastening nut 9 is rotated to fix the second support arm 3, and the fastening bolt 10 is rotated to rotate relative to the adjusting head support 4 until the adjusting head support 4 can rotate relative to the second support arm 3.
[0051] Then adjust the head support 4 to a suitable angle and then reverse the tightening nut 9 to fix the adjustable head support 4 to the second support arm 3. Finally, fix the single-ear connecting structure 7 and the double-ear connecting structure 6 to the bearing structure 1 through the pressure cover 14. Connect the head frame to the operating bed through the head frame converter 8. The patient lies on the operating bed with the head between the first support arm 2 and the second support arm 3. The adjustable head support 4 and the fixed head support 5 are in contact with both sides of the patient's head respectively, and fix and support the patient's head to facilitate the doctor to perform the operation.
[0052] When the ENT department performs ear treatment on patients, the head frame also uses the head frame converter 8 to cooperate with the operating bed. Medical staff need to first loosen the pressure cap 14 so that the single-ear connection structure 7 and the double-ear connection structure 6 can rotate around the connecting column 12, and then adjust the angle of the first support arm 2 and the second support arm 3 as needed, and at the same time separate the connecting arm 1 61 and the connecting arm 2 62, adjust the two groups of second support arms 3 and the adjustable head support 4 connected thereto, so that the adjustable head support 4 contacts the top of the patient's head and neck respectively, avoiding the patient's ears, providing a larger operating space for the doctor's operation, and the first support arm 2 is adjusted to the vicinity of the fixed head support 5 and the ear on the other side of the patient's head, forming a triangular structure with the two groups of adjustable head support 4 to contact the patient's head, and fix and support the patient's head to facilitate the doctor to perform surgical operations.
[0053] When the patient lies prone on the operating table, the patient places the head on the head support 15 with the face facing downward, and the face is embedded in the groove of the head support 15. If the patient's face is wide, the support ring 151 will be squeezed and deformed, and the support ring 151 plays a certain role in fixing the patient's face. At the same time, the patient's neck is suspended at the suspended opening 155, and the mandibular support 154 rests on the patient's mandible, cooperating with the support ring 151 to support the patient's head, and cooperating with the first support arm 2 and the second support arm 3 to support the patient's head. and fixation; when the patient lies on the operating table in a supine position, the head is resting on the head support 15, and the back of the patient's head is embedded in the positioning groove 156. The positioning groove 156 is adapted to the back of the human head. The patient's head is in closer contact with the support ring 151, which increases the stability of the support ring 151. The back of the patient's neck is in contact with the mandibular support 154, and the mandibular support 154 cooperates with the support ring 151 to support the patient's head and neck, and at the same time cooperates with the first support arm 2 and the second support arm 3 to support and fix the patient's head.
