Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a high-precision fixing and quick-disassembly head support device. Background Art

[0002] When conducting modern medical examinations and treatments, the examinee is often required to maintain a specified body position until the diagnosis or operation is completed. Among them, a headrest is often required to be added to the end of the examination bed so that the examinee's head can be extended and away from the examination bed, which is convenient for fixing the examinee's head and facilitating the subsequent work. For example, when a hospital conducts an X-ray cranial tomography examination, a headrest will be installed at the end of the bed and medical staff will be required to fix the examinee's head on the headrest. For another example, after a cerebral angiography examination is performed on a patient with an intracranial aneurysm, an interventional embolization treatment surgery for the intracranial aneurysm may be performed. This surgery requires that the patient's head position cannot be offset. Therefore, it is very necessary to invent a headrest device that can achieve high-precision fixation.

[0003] Conventional methods for fixing head supports include screw fixing, clip fixing, and cavity fixing. Among them, the screw fixing method has the disadvantages of requiring special tools, being time-consuming and labor-intensive to install and remove, being inefficient, and easily causing bacterial contamination on the inspection or surgical platform. It is therefore suitable for long-term use after a single fixation. The clip fixing method has a higher installation efficiency, but still requires manual pinching of the clip to release the connection during removal. The cavity fixing method can only limit the head support from shaking left and right, but often cannot limit its withdrawal. When the examinee adjusts their posture, the head support is easily pushed out, causing it to fall. Therefore, it is necessary to invent a head support device that can achieve quick disassembly.

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] The present invention discloses a high-precision fixing and quick-disassembly head support device, such as Figure 1 As shown, it includes a head support plate 1, a slider 2, a positioning rod 3, an elastic body 4, a limit block 5 and a head support 6, wherein the slider 2 and the head support 6 can slide on the head support plate 1.

[0038] The headrest support plate 1 can be fixed on the examination bed board, or can be integrated with a bracket in the form of a bed board.

[0039] The slider 2 may be a symmetrical structure or a single-sided structure. In one embodiment of the present invention, the slider 2 is preferably a symmetrical structure, which can evenly distribute the thrust of the headrest 6 .

[0040] The headrest support plate 1 is mounted with a slider guide structure 101 and a headrest guide structure 105. The slider guide structure 101 guides the slider 2 as it slides on the headrest support plate 1, while the headrest guide structure 105 guides the headrest 6 as it slides on the headrest support plate 1. Therefore, the headrest support plate 1 not only supports the headrest 6 but also guides it during installation and removal, preventing it from swaying, further enabling high-precision positioning of the headrest 6. The headrest guide structure 105 is provided with a guide structure notch 1051.

[0041] A positioning rod 3 is installed between the head support support plate 1 and the slider 2. Specifically, a first protrusion 102 is provided on the head support support plate 1, and a positioning rod guide groove 201 is provided on the slider 2. The first end of the positioning rod 3 is rotatably connected to the head support support plate 1 through the first protrusion 102, that is, the first end of the positioning rod 3 is fixed to a fixed position of the head support support plate 1 through the first protrusion 102 and the positioning rod 3 can rotate around the first protrusion 102; Figure 5 As shown, the second end of the positioning rod 3 is provided with a positioning rod protrusion 301. The positioning rod protrusion 301 can slide unidirectionally within the positioning rod guide groove 201 according to the tracking function of the specified route. The sliding path in the positioning rod guide groove 201 is a closed path. The positioning rod guide groove 201 includes a plurality of steps. The tail of the previous step is connected to the head of the next step, and the tail of the last step is connected to the head of the first step. There is a step difference at the connection between the steps, that is, the tail of the step is higher than the head of the step at the connection between the steps. The step difference between the steps ensures that the positioning rod protrusion 301 can only track unidirectionally along the specified route, preventing it from falling back. The cooperation between the inner ring profile of the positioning rod guide groove 201 and the step can stably fix the positioning rod protrusion 301 at position A and position B in the positioning rod guide groove 201, wherein position A is the position of the slider 2 relative to the head support plate 1 before the head support 6 is installed, and position B is the position of the slider 2 relative to the head support plate 1 after the head support 6 is installed. When the head support 6 is inserted into the head support plate 1 along the head support guide structure 105, the slider 2 is pushed and triggers the positioning rod protrusion 301 to enter position B of the positioning rod guide groove 201 from position A in the positioning rod guide groove 201. When the head support 6 is pulled out of the head support plate 1 along the head support guide structure 105, the elastomer 4 pulls the slider 2 and triggers the positioning rod protrusion 301 to enter position A of the positioning rod guide groove 201 from position B in the positioning rod guide groove 201.

[0042] In one embodiment of the present invention, Figure 4As shown, the interior of the positioning rod guide groove 201 includes a first step 2011, a second step 2012, a third step 2013 and a fourth step 2014. The tail of the first step 2011 is connected to the head of the second step 2012, the tail of the second step 2012 is connected to the head of the third step 2013, the tail of the third step 2013 is connected to the head of the fourth step 2014, and the tail of the fourth step 2014 is connected to the head of the first step 2011. The tail of the first step 2011 is higher than the head of the second step 2012, the tail of the second step 2012 is higher than the head of the third step 2013, the tail of the third step 2013 is higher than the head of the fourth step 2014, and the tail of the fourth step 2014 is higher than the head of the first step 2011. Therefore, the positioning rod protrusion 301 slides in the positioning rod guide groove 201 in the direction of the first step 2011-second step 2012-third step 2013-fourth step 2014-first step 2011. The inner contour of the positioning rod guide groove 201 has two locations protruding in the direction opposite to the resetting direction of the elastic body 4: the head of the first step 2011 and the head of the third step 2013. The head of the first step 2011 is located in the opposite direction of the resetting direction of the elastic body 4 relative to the head of the third step 2013. Therefore, the head of the first step 2011 is position A, and the head of the third step 2013 is position B. The resetting direction of the elastic body 4 is the direction in which the headrest 6 is withdrawn during disassembly. When installing the head support 6, the positioning rod protrusion 301 moves from position A, i.e., the head of the first step 2011, along the direction of the first step 2011-the second step 2012-the third step 2013, to the head of the third step 2013 and is fixed at the head of the third step 2013, i.e., position B; when disassembling the head support 6, the positioning rod protrusion 301 moves from position B, i.e., the head of the third step 2013, along the direction of the third step 2013-the fourth step 2014-the first step 2011, to the head of the first step 2011 and is fixed at the head of the first step 2011, i.e., position A.

[0043] In one embodiment of the present invention, more than one positioning rod 3 is installed between the head support plate 1 and the slider 2, each positioning rod 3 is connected to the head support plate 1 through a first protrusion 103, and each positioning rod 3 is connected to the slider 2 through a positioning rod guide groove 201. A positioning rod linkage protrusion 302 is provided on the positioning rod 3, and the positioning rod linkage protrusions 302 in different positioning rods 3 are connected through a positioning rod linkage rod 7. The positioning rod linkage protrusion 302 cooperates with the positioning rod linkage rod 7 to realize the synchronous movement of different positioning rods 3 and the linkage effect of one positioning rod 3 driving another one or more positioning rods 3, which can coordinate and make the positioning rods move synchronously to prevent unilateral jamming.

[0044] An elastic body 4 is installed between the head support plate 1 and the slider 2, wherein the elastic body 4 itself can achieve elastic contraction and elastic extension. In one embodiment of the present invention, the elastic body 4 can be made of metal or non-metal, and can be one or more flexible elastic ropes, a compressible inflatable rubber bag, an elastic spring, etc. Specifically: a second slider reset protrusion 103 is provided on the head support plate 1, and a first slider reset protrusion 202 is provided on the slider 2. The first end of the elastic body 4 is rotatably connected to the head support plate 1 through the second slider reset protrusion 103, that is, the first end of the elastic body 4 is fixed to a fixed position of the head support plate 1 through the second slider reset protrusion 103 and the elastic body 4 can rotate around the second slider reset protrusion 103; the second end of the elastic body 4 is rotatably connected to the slider 2 through the first slider reset protrusion 202, that is, the second end of the elastic body 4 is fixed to a fixed position of the slider 2 through the first slider reset protrusion 202 and the elastic body 4 can rotate around the first slider reset protrusion 202. When installing the head support 6, the head support 6 is inserted to cause relative displacement between the head support support plate 1 and the slider 2, the positioning rod protrusion 301 moves from position A in the positioning rod guide groove 201 to position B, and the elastomer 4 undergoes elastic deformation; when removing the head support 6, the positioning rod protrusion 301 returns from position B in the positioning rod guide groove 201 to position A under the action of the elastic force of the elastomer 4, the head support support plate 1 and the slider 2 return to the relative position before installation, and the head support 6 pops out, realizing quick removal of the head support 6.

[0045] Two or more elastic bodies 4 can be installed symmetrically between the headrest support plate 1 and the slider 2, or one or more elastic bodies 4 can be installed asymmetrically. Each elastic body 4 is connected to the headrest support plate 1 via a second slider reset protrusion 103, and each elastic body 4 is connected to the slider 2 via a first slider reset protrusion 202. In one embodiment of the present invention, the elastic bodies 4 are preferably arranged symmetrically on both sides of the slider 2, so that the slider 2 can be forced to reset and retract from both sides, further ensuring that the headrest 6 is evenly stressed and ejected.

[0046] A limit block 5 is installed between the head support support plate 1 and the slider 2. Specifically, a limit protrusion 104 is provided on the head support support plate 1, and a limit block guide protrusion 203 is provided on the slider 2. The first end of the limit block 5 is rotatably connected to the head support support plate 1 through the limit protrusion 104, that is, the first end of the limit block 5 is fixed to a fixed position of the head support support plate 1 through the limit protrusion 104 and the limit block 5 can rotate around the limit protrusion 104; Figure 6As shown, the limit block 5 is provided with a limit block guide groove 501, and the limit block guide protrusion 203 can slide in the limit block guide groove 501 to realize the guiding function of the limit block 5. The movement of the slider 2 drives the limit block guide protrusion 203 to slide in the limit block guide groove 501, which can trigger the extension and retraction actions of the limit block 5. When the head support 6 is inserted into the head support support plate 1 and the installation is completed, the limit block 5 can limit the head support 6 from being pulled out, wherein: when the head support 6 is installed, the head support 6 is inserted into the head support support plate 1 to cause the head support support plate 1 and the slider 2 to move relative to each other, triggering the limit block 5 to extend. When the limit block 5 extends, it can pass through the guide structure notch 1051 provided in the head support guide structure 105 and embed into the head support groove 601 provided on the head support 6, thereby limiting the relative position of the head support 6 and the slider 2, and cooperating with the positioning rod 3 to further fix the relative position of the head support 6 and the head support support plate 1, that is, it plays a role in locking the position of the head support 6 and limiting the head support 6 from being pulled out; when the head support 6 is disassembled, the head support support plate 1 and the slider 2 return to their relative position before installation under the action of the elastomer 4, and the limit block 5 retreats, without locking the position of the head support 6 and allowing the head support 6 to be freely pulled out.

[0047] Two or more limit blocks 5 can be installed symmetrically between the headrest support plate 1 and the slider 2, or one or more limit blocks 5 can be installed asymmetrically. Each limit block 5 is connected to the headrest support plate 1 via a limit protrusion 104, and each limit block 5 is connected to the slider 2 via a limit block guide protrusion 203. In one embodiment of the present invention, the limit blocks 5 are preferably arranged symmetrically on both sides of the headrest 6. In this case, the headrest grooves 601 are also arranged symmetrically on both sides of the headrest 6, which can better lock the position of the headrest 6 and limit the withdrawal of the headrest 6 at the same time, so as to evenly distribute the force.

[0048] The head support plate 1 and the first protrusion 103 , the second slider reset protrusion 103 and the limiting protrusion 104 provided on the head support plate 1 can be integrated into one body, or can be separated into a combination of multiple parts.

[0049] In the present invention, the slider guide structure 101 and the head support guide structure 105 constitute a guide mechanism, and the head support support plate 1, the slider 2 and the positioning rod 3 constitute a positioning mechanism. The guide mechanism and the positioning mechanism together can achieve a guiding function during installation and removal of the head support and a high-static positioning of the head support during installation, and can always keep the head support in a fixed position, with good position consistency, simple components, stable and reliable operation, and reduce the time for medical personnel to install and debug the equipment;

[0050] The head support plate 1, the slider 2 and the elastic body 4 form a reset mechanism. When the head support 6 is pressed again, the head support 6 can be ejected. The slider 2 can be reset and the head support 6 can be ejected when the head support is removed, so that the head support can be quickly removed and the need for quick installation and removal of the head support can be met during modern medical examinations.

[0051] The head support plate 1, the slider 2, the positioning rod 3 and the limiting block 5 form a limiting mechanism, which can realize the self-locking of the position of the head support 6 when the head support 6 is installed, preventing the medical staff from accidentally touching the head support 6 and causing the head support 6 to shift, thereby reducing the obstruction of the head support during medical examinations and reducing the risk of endangering surgical safety;

[0052] The positioning rod 3 and the positioning rod linkage rod 7 form an anti-stuck mechanism, which can prevent the reset mechanism or the limit mechanism from getting stuck. Through the cooperation of the limit mechanism and the anti-stuck mechanism, the head support 6 can be smoothly self-locked after insertion and can always keep the head support 6 in a fixed position.

[0053] The method of using the head support device of the present invention is as follows:

[0054] Before the headrest 6 is installed, the headrest support plate 1 and the slider 2 are in the first relative position. At this time, the positioning rod protrusion 301 is located at position A in the positioning rod guide groove 201, the elastic body 4 is in the first state, and the limit block 5 is in the retracted state. Figure 2 As shown;

[0055] When installing the head support 6, as the head support 6 is inserted into the head support support plate 1 along the head support guide structure 105, the slider 2 is pushed along the slider guide structure 101 and along the direction of insertion of the head support 6, and the positioning rod protrusion 301 is triggered to enter the position B of the positioning rod guide groove 201 from position A in the positioning rod guide groove 201. The elastomer 4 is elastically deformed as the head support support plate 1 and the slider 2 are relatively displaced. The limit block 5 changes from a retracted state to an extended state as the head support support plate 1 and the slider 2 are relatively displaced. Until the installation is completed, the head support support plate 1 and the slider 2 are in the second relative position. At this time, the positioning rod protrusion 301 is located at position B in the positioning rod guide groove 201, the elastomer 4 is in the second state, and the limit block 5 is in an extended state, passing through the guide structure notch 1051 and embedding into the head support groove 601, thereby limiting the position of the head support 6. Figure 3 As shown;

[0056] When removing the head support 6, first push the head support 6 to further change the relative position between the head support support plate 1 and the slider 2, triggering the positioning rod protrusion 301 to leave position B of the positioning rod guide groove 201, and then under the action of the elastic force of the elastomer 4, the positioning rod protrusion 301 slides to position A in the positioning rod guide groove 201, and the relative position between the head support support plate 1 and the slider 2 changes. The limit block 5 changes from an extended state to a retracted state as the head support support plate 1 and the slider 2 are relatively displaced. Until the disassembly is completed, the head support support plate 1 and the slider 2 return to the first relative position. At this time, the positioning rod protrusion 301 returns to position A in the positioning rod guide groove 201, the elastomer 4 returns to the first state, the limit block 5 returns to the retracted state, and the head support 6 can be freely pulled out.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
