[0038] Referring to Figures 1 to 2 The head support device provided by the present application comprises a fixing plate 10, a support frame 20 and a clamping mechanism 30. The fixing plate 10 is used to be connected to the head end of a surgical bed. One end of the support frame 20 is hingedly connected to the fixing plate 10 through a hinge seat 11. The support frame 20 comprises three support rods 21. Two adjacent support rods 21 are hingedly connected. The lower support rod 21 is hingedly connected to the fixing plate 10 through the hinge seat 11. The clamping mechanism 30 is used to clamp the head of a patient. The upper support rod 21 is hingedly connected through a support assembly 40. The clamping mechanism 30 comprises a main support piece 31 and an auxiliary support piece 32. Both the main support piece 31 and the auxiliary support piece 32 are U-shaped structures. The middle parts of the main support piece 31 and the auxiliary support piece 32 are hingedly connected, so that the auxiliary support piece 32 rotates relative to the middle part of the main support piece 31. The fixing plate 10 and the head end of the surgical bed are both provided with a plurality of matching mounting holes 12. The fixing plate 10 is mounted on the head end of the surgical bed through bolts and nuts, so as to fix the support device on the surgical bed and play a supporting role.

[0039] In use, the fixing plate 10 is mounted on the head end of the surgical bed, which has a supporting effect on the device. Then, the position of the clamping mechanism 30 is adjusted through the support frame 20, so that the main support piece 31 clamps and fixes the head, so that the head of the patient remains stationary during the operation. When it is necessary to adjust the position of the head and replace the clamping and fixing point of the head, the auxiliary support piece 32 is used to assist in clamping and fixing the head, so that the main support piece 31 can be disengaged and then clamped and fixed, thereby facilitating the operation of the doctor.

[0040] Referring to 3 and Figure 4, specifically, the main support 31 comprises a main support frame 311 and two rotating rods 312 and two main clamping heads 313, the main support frame 311 is a U-shaped structure, the main support frame 311 is rotationally connected to the support assembly 40, the two rotating rods 312 are respectively rotationally connected to the top surfaces of the two ends of the main support frame 311, the top surfaces of the two rotating rods 312 are each provided with a first clamping groove 318 in the vertical direction, the top side surfaces of the two rotating rods 312 are each provided with a first through hole, the first through hole is in communication with the first clamping groove 318, the bottom of each of the two main clamping heads 313 is fixedly connected with a clamping block 314, the bottom of each of the two clamping blocks 314 is respectively inserted into the two first clamping grooves 318 and rotationally connected, a main clamping bolt 315 is inserted into each first through hole, the end of the main clamping bolt 315 penetrates through the first through hole, penetrates through the bottom of the clamping block 314 and is threadedly connected with a main clamping knob 316, the orientation of the main clamping head 313 can be adjusted by loosening and tightening the main clamping knob 316. Wherein, the top end surface of the main support frame 311 is provided with a fixing knob 317, the bottom of the rotating rod 312 is rotationally embedded in the top inside of the main support frame 311, the rotating rod 312 can be loosened and tightened by the fixing knob 317, so as to adjust the orientation direction of the main clamping head 313.

[0041] When the position of the main support frame 311 is adjusted by the support frame 20, the rotating rod 312 is rotated, the orientation direction of the main clamping head 313 is adjusted, and the fixing knob 317 is tightened; then the main clamping head 313 is rotated, so that the tip of the main clamping head 313 moves upward or downward, the alignment angle of the main clamping head 313 is adjusted, the main clamping knob 316 is tightened, and the position of the main clamping head 313 at this time is fixed, so that the two main clamping heads 313 are clamped on the head of the patient, and the head of the patient is fixed and supported.

[0042] Please refer to 5, the auxiliary support 32 comprises a first auxiliary rod 321 and a second auxiliary rod 322, the first auxiliary rod 321 and the second auxiliary rod 322 are both L-shaped structures and are symmetrically arranged, the bottom side ends of the first auxiliary rod 321 and the second auxiliary rod 322 are both rotationally connected to the support assembly 40, so that the first auxiliary rod 321 and the second auxiliary rod 322 can rotate relative to the middle part of the closed end of the main support frame 311, the outer side surface of the main support frame 311 is provided with a U-shaped structure avoiding groove 33, the first auxiliary rod 321 and the second auxiliary rod 322 can be rotationally accommodated in the avoiding groove 33, the top side ends of the first auxiliary rod 321 and the second auxiliary rod 322 are both hingedly connected with auxiliary clamping heads 323, and the two auxiliary clamping heads 323 can respectively rotate relative to the first auxiliary rod 321 and the second auxiliary rod 322.

[0043] When it is necessary to adjust the position of the head or change the clamping point of the head, the first auxiliary rod 321 and the second auxiliary rod 322 are rotated out respectively, so that the first auxiliary rod 321 and the second auxiliary rod 322 are rotated to the corresponding positions. The auxiliary clamping head 323 is aligned with the clamping point of the head and clamped and fixed on the patient's head. Then, the main clamping head 313 is removed from the head, moved to the subsequent clamping point position, and then clamped on the patient's head again, so that the subsequent clamping of the main clamping head 313 can be carried out stably.

[0044] Preferably, the auxiliary support member 32 further includes two auxiliary screws 324. The end faces of the top sides of the first auxiliary rod 321 and the second auxiliary rod 322 are provided with through first screw holes in the vertical direction. The two auxiliary screws 324 are respectively threaded into the two first screw holes, and the top and bottom ends of the auxiliary screws 324 extend to the outer sides of the two ends of the first screw holes.

Each auxiliary clamping head 323 has clamping plates 327 on both sides of its bottom. The top of the auxiliary screws 324 is inserted between the two clamping plates 327. The auxiliary clamping bolt 325 rotates through the clamping plate 327 and the top of the auxiliary screws 324 and is threaded to the auxiliary clamping knob 326.

[0045] When the auxiliary support 32 is needed, the first auxiliary rod 321 and the second auxiliary rod 322 are unscrewed from the clearance groove. The auxiliary screw 324 is rotated, allowing it to rotate within the first screw hole, thus raising or lowering relative to the first or second auxiliary rod 321 or 322. This adjusts the height of the auxiliary clamping head 323, ensuring it is clamped at the corresponding position on the head. Loosening the auxiliary clamping knob 326 adjusts the orientation of the auxiliary clamping head 323, and tightening it again fixes the alignment of the auxiliary clamping head 323, facilitating alignment with the clamping point on the head. Furthermore, when the first auxiliary rod 321 and the second auxiliary rod 322 need to be retracted into the clearance groove 33, the auxiliary screw 324 is rotated to lower the height of the auxiliary clamping head 323, allowing it to retract into the clearance groove 33.

[0046] like Figure 1 , Figure 6 and Figure 7As shown, in the embodiment, the support assembly 40 comprises a support column 41, a first rotating ring 42 and a second rotating ring 43, the top end of the support column 41 is rotatably penetrated through the closed end of the main support frame 311 and extends to the inner side thereof, the first rotating ring 42 and the second rotating ring 43 are rotatably sleeved on the middle part of the support column 41 respectively, the bottom side end of the first auxiliary rod 321 is fixedly connected with the first rotating ring 42, and the bottom side end of the second auxiliary rod 322 is fixedly connected with the second rotating ring 43. Among them, the outer side of the middle part of the support column 41 is fixedly sleeved with two limiting rings 44 distributed upward and downward, the inner side surfaces of the first rotating ring 42 and the second rotating ring 43 are respectively provided with two limiting grooves 45, and the two limiting rings 44 are respectively inserted into the two limiting grooves 45 for rotation connection. Among them, the top of the support column 41 is provided with a support pad 60, which is convenient for the placement of the head.

[0047] When the first auxiliary rod 321 and the second auxiliary rod 322 are rotated out of the avoiding groove, the first rotating ring 42 and the second rotating ring 43 are rotated relative to the support column 41, and due to the arrangement of the limiting ring 44 and the limiting groove 45, the rotation stability of the first rotating ring 42 and the second rotating ring 43 is enhanced.

[0048] Preferably, the support assembly 40 comprises a first locking knob 46 and a second locking knob 47, the end of the first locking knob 46 is threaded through the first rotating ring 42 and can abut on the corresponding limiting ring 44, the end of the second locking knob 47 is threaded through the second rotating ring 43 and can abut on the corresponding limiting ring 44; the outer side of the middle part of the support column 41 is fixedly sleeved with a supporting ring 49, the supporting ring 49 is located above the first rotating ring 42, and the bottom surface of the main support frame 311 can be attached to the top surface of the supporting ring 49, so that the supporting ring 49 supports the main support frame 311; the main support frame 311 is provided with a third locking knob 48, the end of the third locking knob 48 is threaded through the main support frame 311 and abuts on the support column 41.

[0049] As Figure 2As shown, in the embodiment, the main clamping head 313 and the auxiliary clamping head 323 are the same structure, taking the main clamping head 313 as an example. The main clamping head 313 comprises a clamping block 51 and a clamping screw 52, the bottom of the clamping block 51 is fixedly connected to the top of the rotating rod 312, a through screw hole is formed in the middle of the clamping block 51, and the clamping screw 52 is threadedly arranged in the screw hole. The end of the clamping screw 52 facing the head is a sharp end, which is convenient for clamping and fixing the head. The bottom of the clamping block 51 in the auxiliary clamping head 323 is fixedly connected to the top of the two clamping plates 327. By rotating the clamping screw 52, the end of the clamping screw 52 moves towards the head, thereby abutting against the head.

[0050] As shown in Figure 1 and Figure 2 As shown, in the embodiment, the ends of the two adjacent support rods 21 are hingedly connected through the locking member 22, which can be screwed or loosened. The hinging of the upper support rod 21 with the support assembly 40 and the hinging of the lower support rod 21 with the hinging seat 11 are also through the locking member 22, which can be screwed or loosened. By adjusting the positions of the three support rods 21, the main support frame 311 is moved to the corresponding position to clamp and fix the head of the patient. The ends of the three support rods 21 are locked by the locking member 22, thereby fixing the positions of the three support rods 21 at this time. The locking member 22 can be a combination of a bolt and a nut.

[0051] The working principle of the present application is as follows: in use, first, the fixed plate 10 is installed on the head end of the operating bed, which has a supporting effect on the device; then, the positions of the three support rods 21 are adjusted, so that the main support frame 311 moves to the corresponding position, and the three support rods 21 are locked and fixed by the locking member 22, thereby fixing the position of the main support frame 311 at this time; then, the main clamping head 313 is rotated, and the orientation of the main clamping head 313 is adjusted, so that the sharp end of the main clamping head 313 is aligned with the clamping point of the head, and the clamping screw 52 is rotated to move the clamping screw 52 to abut against the head;

[0052] When it is necessary to adjust the position of the head and replace the clamping and fixing point of the head, the first auxiliary rod 321 and the second auxiliary rod 322 are rotated out of the avoiding slot, the auxiliary screw 324 is rotated, the height position of the auxiliary clamping head 323 is adjusted, and at the same time, the sharp end of the auxiliary clamping head 323 is aligned with the clamping point of the head, the auxiliary clamping knob 326 is tightened, the orientation of the auxiliary clamping head 323 at this time is fixed, the clamping screw 52 is rotated to move the clamping screw 52 to abut against the head, then the main clamping head 313 is loosened, the main clamping head 313 is moved to the subsequent clamping position, the main clamping head 313 is tightened for head fixation, and finally the first auxiliary rod 321 and the second auxiliary rod 322 are retracted into the avoiding slot.
