Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically a subclavian avoidance head support frame for permanent pacemaker implantation. Background Technology

[0002] In the clinical setting of permanent pacemaker implantation, traditional postural support devices have many limitations. One is insufficient adaptability. The support height and angle of conventional pacemaker implantation surgery pillows and other devices are mostly fixed or roughly adjustable manually, which cannot achieve precise adaptation according to different physical characteristics such as patient height, weight, and shoulder width. This can easily lead to the patient's shoulders, head and support components not fitting tightly.

[0003] Patent application number CN202422012692.3 discloses a special pillow for pacemaker implantation surgery, including a base plate, a headrest detachably mounted on the base plate, a groove in the middle of the top surface of the headrest, two placement holes on the top surface of the headrest, a head airbag placed inside the placement holes, and a shoulder pillow connected to the front side of the headrest, a shoulder airbag placed inside the shoulder pillow. In the above-mentioned approach, medical staff can inflate the left head airbag and shoulder airbag. When the head airbag increases in volume, it can support the left side of the patient's head, causing the patient's head to shift to the right, thereby fixing the head. The shoulder airbag supports the patient's shoulders, ensuring that the patient does not experience fatigue when in the same position for a long time, thus improving the patient's comfort during the operation and facilitating the smooth progress of the operation. However, the above approach lacks dynamic monitoring and correction capabilities. Traditional equipment can only achieve initial position fixation. During the operation, the patient is prone to positional shifts due to slight body movements, which medical staff may find difficult to detect and adjust in time. This may interfere with the operation in the subclavian region, affecting the accuracy and safety of the operation.

[0004] Therefore, in order to solve the above-mentioned technical problems, the present invention proposes a subclavian avoidance head support for permanent pacemaker implantation. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems. This invention provides a subclavian avoidance head support frame for permanent pacemaker implantation, which has the advantages of intelligent sensing, automatic adjustment, and real-time correction.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a subclavian avoidance head support frame for permanent pacemaker implantation, comprising a support assembly, a control terminal connected to the support assembly, the support assembly including a connecting box, a working cavity with an opening at one end opened in the connecting box, an adjustment assembly connected in the working cavity, and multiple shoulder support assemblies and head supports respectively connected to the adjustment assembly, wherein the multiple shoulder support assemblies are close to the opening of the working cavity; The shoulder support assembly includes a housing, one end of which is connected to the adjustment assembly. Two sidewalls are connected to the end of the housing away from the adjustment assembly. The two sidewalls are connected at both ends along the length of the housing. Two elastic plates are connected between the two sidewalls. The two elastic plates are located at both ends of the housing along the width direction. An installation cavity is formed between the two sidewalls and the two elastic plates. Multiple force-bearing components are connected inside the installation cavity. The two elastic plates are connected to a support plate at one end away from the housing. One end of the support plate is connected to the force-receiving component. The support plate is provided with two elastic bladders at the end away from the force-receiving component.

[0007] Preferably, the two sidewalls are slidably provided with sliding parts at the ends away from the housing, one end of the sliding parts is connected to the support plate, and the support plate is provided with an air inlet communicating with the elastic bladder at one end distributed along the length direction.

[0008] Preferably, each of the force-bearing components includes a horizontal plate, the length direction of which is parallel to the width direction of the mounting cavity. Two diagonal rods are hinged to one end of the horizontal plate, and the two diagonal rods are respectively located on both sides of the horizontal plate along its length direction. A swing rod is hinged to the end of the two diagonal rods away from the horizontal plate, and both sides of the swing rod along its length direction are connected to the support plate.

[0009] Preferably, the two diagonal bars are distributed in a figure-eight shape on the horizontal plate, and the distance between the two diagonal bars and the horizontal plate is greater than the distance between the two diagonal bars and the horizontal plate.

[0010] Preferably, the horizontal plate has two grooves at one end near the swing rod, and a support rod is connected in the groove. The end of the support rod away from the groove is hinged to the inclined rod.

[0011] Preferably, the head support includes a concave portion, and an auxiliary component is provided on the side of the concave portion near the control component. The auxiliary component is located in the groove of the concave portion, and both the concave portion and the auxiliary component are connected to the control component.

[0012] Preferably, the concave portion includes a connecting block, on which a movable block for head support is movably provided, and protective pouches are respectively provided at both ends of the connecting block near the auxiliary component.

[0013] Preferably, the auxiliary component includes a fixing plate, an adjusting rod is connected to the end of the fixing plate away from the regulating component, and a pad is connected to the end of the adjusting rod away from the fixing plate.

[0014] Preferably, a storage box is connected to the connecting box, a light-transmitting plate for observing the working conditions inside the working chamber is connected to the cavity wall of the working chamber, an inflation assembly is connected inside the cavity wall of the working chamber, and the inflation assembly is electrically connected to the control terminal.

[0015] Preferably, the control component includes a mounting plate, and a lifting rod is connected to one end of the mounting plate away from the shoulder support component.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The adjustable components and shoulder support components work together to adapt to and initially fix the body position of patients with different vital signs. Medical staff can adjust the initial height based on the patient's height, shoulder width and other basic information. The sliding part ensures the flexibility of the support plate deflection. The flexible material of the support plate can also be elastically deformed to adapt to the patient's shoulder shape. Then the inflation component inflates the elastic bladder in a certain amount of air, so that it makes slight contact with the shoulder to achieve initial shoulder fixation and ensure initial stability of the body position.

[0017] 2. Through the combination of the head support and auxiliary components, coordinated support and pressure balance of the head and neck can be achieved. After the patient's head is placed against the concave movable block, the spacing of the movable block can be adjusted to adapt to different head shapes, and the flexible pressure sensing membrane on its surface can monitor the pressure distribution; the protective bladders at both ends of the connecting block can make slight contact with the sides of the head after inflation, reducing soreness and swelling, and the pad fits against the neck to form coordinated support for the head and neck. When the sensing membrane detects that the local pressure is too high, the control terminal will instruct the adjustment rod to raise or lower to change the neck support height, and at the same time control the corresponding protective bladder to deflate slightly, so as to achieve uniform pressure distribution of the head and neck and reduce the discomfort of prolonged fixed position.

[0018] 3. The elastic bladder continuously feeds back air pressure and pressure data to the control terminal. When the air pressure of the elastic bladder deviates, the control terminal will instruct the inflation component to slightly inflate and deflate the elastic bladder on the deviated side. At the same time, it will adjust the sliding of the support rod of the force-bearing component to drive the diagonal rod to deflect and finely adjust the support plate to the reference angle, so as to avoid the deviation from increasing and maintain the stability of the patient's position throughout the operation.

[0021] 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.

[0022] like Figures 1-8As shown, this invention discloses a subclavian avoidance head support frame for permanent pacemaker implantation, including a support component 1 for connection and support. A control terminal 3 is connected to the support component 1 for receiving and regulating the support status of the head support frame. The support component 1 includes a connecting box 101, with a working cavity 102 having an opening at one end. This allows the user's head to be easily placed into the working cavity 102 during use. A height adjustment component 4 is connected to the working cavity 102. Multiple shoulder support components 5 and head supports 6 are connected to the adjustment component 4, with the shoulder support components 5 positioned near the opening of the working cavity 102. The height of the adjustment component 4 is adjusted according to the user's body shape to change the height of the shoulder support components 5 and head supports 6, ensuring full contact between the user and the shoulder support components 5 and head supports 6 during use and maintaining the user's stability during surgery.

[0023] It should be noted that, in this invention, the number of multiple shoulder support components 5 is preferably three, and the three are evenly distributed on the adjustment component 4, so as to achieve stable support for both shoulders and the back.

[0024] The shoulder support component 5 includes a fixed housing 501. One end of the housing 501 is connected to the adjustment component 4. Two side walls 504 are connected to the end of the housing 501 away from the adjustment component 4. The two side walls 504 are connected at both ends along the length of the housing 501. The ends of the two side walls 504 away from the housing 501 are arc-shaped. Two elastic plates 502 are connected between the two side walls 504. The two elastic plates 502 are located at both ends of the housing 501 along the width direction. So that when the user uses it, the two elastic plates 502 can be compressed and deformed according to the force applied, without causing deformation. This affects the user's experience. An installation cavity 5011 is provided between the two side walls 504 and the two elastic plates 502. Multiple force-bearing components 8 are connected in the installation cavity 5011 to identify the force state when the user is using the device. The end of the two elastic plates 502 away from the housing 501 is connected to a support plate 505. One end of the support plate 505 is connected to the force-bearing components 8. The end of the support plate 505 away from the force-bearing components 8 is provided with two elastic bladders 506 to improve the user's comfort and stability. The two elastic bladders 506 are distributed on both sides of the support plate 505 along the width direction.

[0025] When the user's shoulder comes into contact with the shoulder support component 5, the shoulder first comes into contact with the surface of the support plate 505. Under the user's own weight, the support plate 505 causes the force-bearing component 8 to move, thereby changing the height and horizontal tilt angle of the support plate 505. This ensures that the state of the support plate 505 is completely adapted to the user's body state. At the same time, the inflation state of the elastic bladder 506 is adjusted according to the deformation state of the support plate 505 to ensure the stability of the force on the support plate 505.

[0026] It should be noted that the end of the support plate 505 away from the force-bearing component 8 is made of a flexible material, which has the state and function of elastic deformation during use. Therefore, when the user moves the two support plates 505 to deflect, the support plate 505 in the middle is compressed, that is, the thickness of the support plate 505 becomes thinner, which will not cause damage to the side wall 504.

[0027] Furthermore, once the user is in full contact with the shoulder support component 5, the support plate 505 supports the user's position. At the same time, the inflation state of the elastic bladder 506 is adjusted according to the compression of the support plate 505 to improve the user's comfort and ensure that the support plate 505 is not over-compressed. Meanwhile, when the support plates 505 on both sides are tilted, the outermost elastic bladder 506 does not contact the human torso. At this time, only the two outermost elastic bladders 506 are inflated, causing them to expand and come into contact with the shoulders on the front of the human body, thereby achieving initial fixation of the user's lying position and preventing the user's posture from moving.

[0028] Furthermore, in order to ensure the deflection sensitivity of the support plate 505 during use, a sliding part 503 is slidably provided at the end of the two side walls 504 away from the housing 501. The arc shape of the sliding part 503 corresponds to the arc shape of the side wall 504. One end of the sliding part 503 is connected to the support plate 505. An air inlet 507 communicating with the elastic bladder 506 is provided on one end of the support plate 505 distributed along the length direction. The air inlet 507 is used to independently realize the inflation and deflation of each elastic bladder 506.

[0029] Furthermore, in order to quickly adjust the tilt state of the support plate 505, each force-bearing component 8 includes a horizontal plate 801 for connection and fixation, which is evenly distributed within the mounting cavity 5011. The length direction of the horizontal plate 801 is parallel to the width direction of the mounting cavity 5011. Two diagonal rods 802 are hinged to one end of the horizontal plate 801, and the two diagonal rods 802 are located on both sides of the horizontal plate 801 along its length. A swing rod 803 is hinged to the end of the two diagonal rods 802 away from the horizontal plate 801, and the swing rod 803 is located on both sides of the horizontal plate 801 along its length. All are connected to the support plate 505. When the support plate 505 is subjected to force on one side, the gravity of the support plate 505 on one side acts on one end of the swing rod 803, which causes the angle of the inclined rod 802 to deflect, causing the included angle between the swing rod 803 and the mounting cavity 5011 to change. When the gravity on the support plate 505 changes, the rotation angle of the inclined rod 802 will change, that is, the tilt angle between the swing rod 803 and the mounting cavity 5011 will change. This allows the user to determine the deviation during use, and facilitates timely correction and protection.

[0030] At the same time, the elastic bladders 506 on both sides can be used to identify the user's body displacement during use. The initial air pressure when the elastic bladder 506 contacts the front shoulder of the human body is the base value, and the air pressure value inside the elastic bladder 506 is kept constant. When the user deviates during use, the volume inside the elastic bladder 506 will change, thereby affecting the air pressure value inside the elastic bladder 506. The user can judge the body displacement state based on the change in air pressure value.

[0031] Furthermore, in order to facilitate the timely deflection of the diagonal braces 802 when subjected to force, the two diagonal braces 802 are distributed in a figure-eight shape on the horizontal plate 801, and the distance between the two diagonal braces 802 and the horizontal plate 801 is greater than the distance between the two diagonal braces 802 and the horizontal plate 801.

[0032] Furthermore, to facilitate the rapid reset of the rotation angle of the inclined rod 802, two sliding grooves 804 are provided at the end of the horizontal plate 801 near the swing rod 803. A support rod 805 with an adjustable length is connected in the sliding groove 804, and a reset spring is provided between the support rod 805 and the sliding groove 804. The end of the support rod 805 away from the sliding groove 804 is hinged to the inclined rod 802. When the inclined rod 802 deflects, it drives the support rod 805 to slide in the sliding groove 804. At the same time, the extension state of the support rod 805 is adjusted according to the rotation of the inclined rod 802. When the user leaves, the reset spring drives the support rod 805 and the inclined rod 802 to reset, restoring the parallel state between the swing rod 803 and the cavity surface of the mounting cavity 5011.

[0033] Furthermore, in order to ensure effective support for the heads of users of different body types, the head support 6 includes a concave portion 601. An auxiliary component 602 for supporting the neck is provided on the side of the concave portion 601 near the control component 4. The auxiliary component 602 is located in the groove of the concave portion 601, and both the concave portion 601 and the auxiliary component 602 are connected to the control component 4. The user's head contacts the concave portion 601, and then the height of the auxiliary component 602 is adjusted to make the auxiliary component 602 contact and support the user's neck.

[0034] Furthermore, the concave portion 601 includes a connecting block 6011, on which a movable block 6012 for head support is movably mounted. The end face of the movable block 6012 is adapted to the shape of the human head. The distance between the movable block 6012 and the connecting block 6011 can be adjusted, thereby adjusting the position of the movable block 6012 according to the user's usage to ensure full contact with the user's head. Protective pouches 6013 are respectively provided at both ends of the connecting block 6011 near the auxiliary component 602. When the user's head contacts the movable block 6012, the protective pouches 6013 are controlled to expand and make slight contact with the sides of the human head, thereby reducing the discomfort caused by prolonged bending of the user's head. A contact pressure sensor is installed in the protective pouch 6013 of the head support 6, and a flexible pressure sensing membrane is laid on the surface of the movable block 6012 to monitor the distribution of head contact pressure.

[0035] When the flexible pressure sensing membrane of the head support 6 detects that the local pressure exceeds the preset threshold, the control terminal 3 automatically starts the pressure equalization program, sends a lifting command to the adjustment rod 6022 of the auxiliary component 602, adjusts the support height of the pad 6023 on the neck, and at the same time controls the protective bladder 6013 in the pressure concentration area to release a small amount of air, so as to achieve a uniform distribution of pressure on the head and neck and reduce the soreness and discomfort of the patient in a fixed position for a long time.

[0036] Furthermore, the auxiliary component 602 includes a fixed plate 6021. The end of the fixed plate 6021 away from the control component 4 is connected to a height-adjustable adjustment rod 6022. The end of the adjustment rod 6022 away from the fixed plate 6021 is connected to a pad 6023. After the human head comes into contact with the movable block 6012, the height of the adjustment rod 6022 is adjusted according to the distance between the pad 6023 and the user's neck, so that the pad 6023 supports the user's neck.

[0037] Furthermore, a storage box 2 for storing emergency medicines and tools is connected to the connecting box 101, a light-transmitting plate 103 for observing the working conditions inside the working chamber 102 is connected to the cavity wall of the working chamber 102, and an inflation assembly 7 for controlling the inflation and deflation of the protective bladder 6013 and the air inlet 507 is connected inside the cavity wall of the working chamber 102. The inflation assembly 7 is electrically connected to the control terminal 3, that is, the control terminal 3 can receive and control the status of the inflation assembly 7.

[0038] Furthermore, in order to ensure that the shoulder support assembly 5 and the head support 6 can make full contact with different users, the adjustment assembly 4 includes a mounting plate 401. The end of the mounting plate 401 away from the shoulder support assembly 5 is connected to a lifting rod 402. The height of the mounting plate 401 is adjusted by using the lifting rod 402 to adjust the height of the shoulder support assembly 5 and the head support 6, thereby ensuring that the device can be used normally.

[0039] To facilitate the reading of air pressure within the elastic bladder 506, a miniature air pressure sensor is embedded inside the elastic bladder 506. This sensor establishes a wireless communication connection with the control terminal 3, enabling real-time acquisition of air pressure data within the elastic bladder 506 to determine the tightness of the fit between the patient's shoulder and the support plate 505. Furthermore, a pressure sensor is added to the slide groove 804 of the horizontal plate 801 of the force-bearing component 8. This sensor contacts the end of the support rod 805 and converts the pressure changes during the swing of the inclined rod 802 into electrical signals, which are then fed back to the control terminal 3 to calculate the tilt angle and force distribution of the support plate 505. A displacement sensor is mounted on the lifting rod 402 of the adjustment component 4 to provide real-time feedback on the height adjustment value of the mounting plate 401, ensuring precise and controllable support height.

[0040] Before the patient lies down, medical staff can input basic vital signs information such as the patient's height, weight, and shoulder width through the control terminal 3. After the patient lies down, the control terminal 3 automatically starts the data acquisition program, synchronously acquires the initial data of each sensor, and, combined with the preset vital signs information, quickly establishes the patient's postural support benchmark parameters, providing data reference for subsequent adjustments.

[0041] After obtaining the baseline parameters using the control terminal 3, an instruction is automatically sent to the lifting rod 402 of the control component 4 to drive the lifting rod 402 to adjust its height, thereby causing the mounting plate 401, shoulder support component 5, and head support component 6 to rise and fall synchronously until they are adapted to the patient's basic body height. Then, the control terminal 3 sends a signal to the inflation component 7, which inflates a fixed amount of air into the shoulder elastic bladder 506 through the air inlet 507, and simultaneously inflates the head protection bladder 6013 initially, so that the elastic bladder 506 and the protection bladder 6013 make slight contact with the patient's shoulders and the sides of the head, respectively, to complete the initial fixation of the body position.

[0042] Furthermore, during the surgery, the control terminal 3 continuously receives real-time data from various sensors. When the air pressure sensor inside the elastic capsule 506 detects that the air pressure value deviates from the initial reference value by ±10%, the system determines that the patient has experienced a positional shift. If the shoulder is deviated on one side, the control terminal 3 controls the inflation component 7 to slightly inflate and deflate the elastic bladder 506 on the deviated side, and at the same time sends an adjustment command to the support rod 805 of the force-bearing component 8 on that side, driving the support rod 805 to slide slightly in the slide groove 804, causing the inclined rod 802 to deflect, thereby making the support plate 505 slightly adjust to the reference tilt angle, so as to realize the shoulder position reset.

[0043] It should be noted that under normal conditions, the support rod 805 is only subjected to the elastic force of the return spring within the slide groove 804. When an abnormal condition occurs, the power source within the slide groove 804 can actively drive the support rod 805 to move within the slide groove 804.

[0044] If the overall body position is deviated, the control terminal 3 synchronously adjusts the inflation and deflation of the elastic bladders 506 of the shoulder support components 5 on both sides, and links the protective bladder 6013 of the head support 6 to assist in limiting the position and prevent the deviation from increasing.

[0045] Before using the device, medical staff can input basic vital signs information such as the patient's height, weight, and shoulder width through the control terminal 3 connected to the support component 1, establishing a data benchmark for subsequent positional adjustments. The inflation component 7 built into the cavity wall is electrically connected to the control terminal 3, providing inflation and deflation power for each sac structure. The storage box 2 on the connection box 101 can store emergency medicines and surgical tools to ensure emergency surgical needs. The adjustment component 4 inside the working cavity 102 is the core of the device's height adaptation. Its lifting rod 402 can drive the mounting plate 401 to adjust its height, thereby simultaneously changing the height of the shoulder support component 5 and the head support component 6 mounted on the mounting plate 401. The displacement sensor mounted on the lifting rod 402 can provide real-time feedback on the height adjustment value, ensuring precise and controllable support height. Medical staff can initially adjust the lifting rod 402 according to the patient's vital signs to place the shoulder support component 5 and the head support component 6 in the initial height range suitable for the patient's body.

[0046] When the patient is lying down, the head is inserted through the opening of the working cavity 102, the shoulders first contact the shoulder support component 5, and the head then fits against the concave portion 601 of the head support component 6. The housing 501 of the shoulder support component 5 is connected to the mounting plate 401 of the adjustment component 4. The two side walls 504 at the end of the housing 501 and the elastic plate 502 enclose the mounting cavity 5011 to form the mounting cavity 5011. Multiple force-bearing components 8 within the mounting cavity 5011 can sense the force state of the shoulder in real time. When the patient's shoulder contacts the surface of the support plate 505, their own weight causes the support plate 505 to move, which in turn causes the swing rod 803 connected to the support plate 505 to deflect. The inclined rods 802 hinged at both ends of the swing rod 803 then rotate on the horizontal plate 801. The deflection of the inclined rods 802 causes the support rod 805 to slide within the groove 804 of the horizontal plate 801. The pressure sensor in the groove 804 converts the pressure change of the support rod 805 into an electrical signal and feeds it back to the control terminal 3 to calculate the tilt angle and force distribution of the support plate 505. At the same time, the sliding part 503 at the end of the side wall 504 can slide synchronously with the deflection of the support plate 505, ensuring the flexibility of the deflection of the support plate 505. Moreover, the end of the support plate 505 away from the force-bearing component 8 is made of flexible material, which can elastically deform according to the force state, avoiding hard damage to the side wall 504.

[0047] After the support plate 505 completes its initial deflection to adapt to the patient's shoulder shape, the control terminal 3 sends a command to the inflation assembly 7, which then inflates the two elastic bladders 506 through the air inlet 507. The miniature pressure sensors embedded in the elastic bladders 506 communicate wirelessly with the control terminal 3, allowing for real-time collection of pressure data to determine the tightness of the shoulder fit. Initially, the elastic bladders 506 make slight contact with the patient's shoulder, achieving initial shoulder fixation. The middle support plate 505 may compress and deform due to pressure from the patient's back. In this case, the control terminal 3 adjusts the inflation amount of the elastic bladders 506 according to the degree of compression to prevent over-compression. For the two side support plates 505, if tilting occurs, only the outermost elastic bladder 506 is inflated, causing it to expand and contact the patient's front shoulder, further enhancing the positional fixation effect.

[0048] At the head support level, the patient's head fits against the movable block 6012 of the concave portion 601. The distance between the movable block 6012 and the connecting block 6011 is adjustable to accommodate the support needs of different head shapes. The flexible pressure-sensing membrane on the surface of the movable block 6012 monitors the head contact pressure distribution. The protective bladders 6013 at both ends of the connecting block 6011 are initially inflated by the inflation component 7 after the head fits, making slight contact with the sides of the head to reduce soreness and swelling from prolonged fixed position. At the same time, the auxiliary component 602 in the groove of the concave portion 601 provides neck support. Medical staff can adjust the height of the adjusting rod 6022 on the fixing plate 6021 according to the distance between the patient's neck and the pad 6023, so that the pad 6023 fits fully with the neck, forming a coordinated support for the head and neck. When the flexible pressure sensing membrane detects that the local pressure exceeds the preset threshold, the control terminal 3 will automatically start the pressure equalization program. On the one hand, it sends a lifting command to the adjustment rod 6022 to adjust the neck support height, and on the other hand, it controls the protective bladder 6013 in the pressure concentration area to release a small amount of air, so as to achieve a uniform distribution of pressure on the head and neck.

[0049] During the surgery, the control terminal 3 continuously receives real-time data from various sensors to achieve dynamic correction of the patient's position. When the air pressure inside the elastic bladder 506 deviates from the initial reference value by ±10%, the system determines that the patient has experienced a positional shift. If it is a unilateral shoulder shift, the control terminal 3 will control the inflation component 7 to slightly inflate and deflate the elastic bladder 506 on the shifted side, and simultaneously send an adjustment command to the support rod 805 of the force-bearing component 8 on that side. This will drive the support rod 805 to slide slightly within the groove 804, causing the inclined rod 802 to deflect and finely adjust the support plate 505 to the reference tilt angle, thus completing the shoulder positional reset. If it is a general positional shift, the control terminal 3 will simultaneously regulate the inflation and deflation of the elastic bladders 506 on both shoulders and coordinate with the head protection bladder 6013 for auxiliary limiting to prevent the shift from widening. In addition, the return spring in the slide groove 804 of the force-bearing component 8 can drive the support rod 805 and the inclined rod 802 to return to their original positions when the patient leaves after surgery, so that the swing rod 803 returns to a parallel state with the cavity surface of the mounting cavity 5011, and is ready for the next use.
