Description

Technical Field

[0001] This application relates to the field of medical device technology, such as a pacemaker surgical folding head frame. Background Technology

[0002] Pacemaker implantation is a common interventional cardiac procedure, typically performed under local anesthesia. The patient remains awake throughout the procedure so the surgeon can assess cardiac function and the patient's responsiveness in real time. While this method reduces the risks associated with general anesthesia, it can also cause psychological stress, especially when the patient is directly observing the surgical procedure, potentially triggering anxiety or fear. To alleviate this psychological burden, sterile drapes or other coverings are usually used to conceal the patient's face during the procedure. This not only prevents negative emotions from the patient directly witnessing the surgery but also effectively maintains the sterility of the surgical area, preventing infection.

[0003] However, directly covering the patient's face with an occluder makes it difficult for doctors to observe the patient's vital signs during surgery, thus affecting the smooth progress of the operation. At the same time, covering the patient's face with an occluder for a long time can easily cause breathing difficulties, which can alter the patient's vital signs and is not conducive to the operation.

[0004] In existing technologies, a frame-type surgical headrest is typically installed at the head of the operating table, supporting the patient's head. Sterile drapes or other coverings are placed on top to obstruct the patient's view and reduce psychological stress. However, before, during, or after surgery, if it is necessary to move the patient or adjust the patient's head position in an emergency, the process of obscuring or exposing the patient's head with the surgical headrest is cumbersome and inconvenient for medical staff.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a pacemaker surgical folding head frame that can improve the folding and unfolding speed of the surgical head frame, and is simple to operate and convenient for medical staff.

[0008] According to a first embodiment provided in this application, a pacemaker surgery folding head frame is provided, comprising: a mounting assembly for connection to the head end of an operating table; a folding assembly including a lap joint and two crossbar groups, the two crossbar groups being laterally spaced along the head end, each crossbar group including a first crossbar and at least one second crossbar rotatably connected, the first crossbar being rotatably connected to the mounting assembly at a first end near the mounting assembly, and the second crossbar being slidable and rotatable relative to the mounting assembly at a first end near the mounting assembly; the lap joint extending laterally along the head end, one end being connected to the second end of the first and / or second crossbar of one crossbar group away from the mounting assembly, and the other end being connected to the second end of the first and / or second crossbar of the other crossbar group away from the mounting assembly.

[0009] In some alternative embodiments, the first end of the second crossbar is slidable relative to the mounting assembly between a first position and a second position along the vertical direction of the head end; when the first end of the second crossbar is in the first position, the crossbar assembly is in an unfolded state, and when the first end of the second crossbar is in the second position, the crossbar assembly is in a folded state, and both the first end of the second crossbar and the first end of the first crossbar are rotatable relative to the mounting assembly.

[0010] In some alternative embodiments, the connector includes a plurality of lap rods, the plurality of lap rods including a first lap rod connecting a second end of a first cross rod in two cross rod groups, and a second lap rod connecting a second end of a second cross rod in two cross rod groups.

[0011] In some alternative embodiments, in any crossbar group, the extension length of the crossbar relatively closer to another crossbar group is less than the extension length of the crossbar relatively farther away from another crossbar group.

[0012] In some alternative embodiments, there is one second crossbar, which is rotatably connected to the first crossbar; or,

[0013] There are multiple second crossbars, which together with the first crossbar form a multi-link crossarm structure.

[0014] In some alternative embodiments, the mounting assembly includes: a mounting bracket for connection to the head end, the end of the mounting bracket having a first sliding structure along the transverse direction of the head end; a support base having a second sliding structure adapted to the first sliding structure, the support base being detachably connected to the end of the mounting bracket via the first and second sliding structures, a first end of a first crossbar being rotatably connected to the support base, and a first end of a second crossbar being capable of sliding and rotating relative to the support base.

[0015] In some alternative embodiments, there are two support bases, which are provided corresponding to the ends of the fixing frame.

[0016] In some alternative embodiments, the support includes a base, a limiting plate, and a hinge plate protruding from the upper sidewall of the base. The limiting plate surrounds the edge of the upper sidewall of the base to limit the second cross rod in the sliding direction. The first end of the first cross rod is rotatably connected to the hinge plate.

[0017] In some optional embodiments, one of the adapted first sliding structure and the second sliding structure has a mounting cavity on its side wall, and an elastic limiting member is provided in the mounting cavity. The other of the adapted first sliding structure and the second sliding structure has a mounting groove on its side wall. When the support is connected to the fixing frame and the support is located in the preset installation position, the elastic limiting member moves toward the mounting groove so as to be located in the mounting groove.

[0018] In some alternative embodiments, the fixing frame includes: a frame body for fitting onto the outer wall of the head end, with first sliding structures at both ends of the frame body along the transverse direction of the head end; a locking member disposed on the side of the frame body facing the head end; and an adjusting member, one end of which passes through the frame body and is threadedly connected to the frame body, for driving the locking member to move toward the head end so as to clamp the head end between the locking member and the frame body.

[0019] The pacemaker surgical folding head frame provided in this embodiment can achieve the following technical effects:

[0020] In this optional embodiment, the folding assembly can be mounted on the lateral side of the head end of the operating table via a mounting assembly. The crossbar assembly includes a first crossbar and at least one second crossbar rotatably connected, with the first end of the second crossbar capable of sliding and rotating relative to the mounting assembly. This relative sliding of the first end of the second crossbar allows the crossbar assembly to be unfolded or folded. The two ends of the lap joint are respectively connected to the second ends of the first and / or second crossbars of the two crossbar assemblies, and the lap joint extends laterally along the head end, allowing the two crossbar assemblies to support the lap joint on the upper side of the patient's head and face. When the crossbar assembly is unfolded, a sterile drape or other covering can be draped over the lap joint to cover the patient's head and face. The cross-arrangement of the first and second crossbars at this time improves the operational stability of the crossbar assembly, thereby enhancing the support stability for the lap joint and the covering.

[0021] When moving the patient or performing operations on the patient's head and face, requiring exposure of the patient's head and face, the covering can be removed. Both the first ends of the first and second crossbars are rotatable relative to the mounting assembly. After the crossbar assembly is folded, it can rotate relative to the mounting assembly to move the connecting piece away from the area above the head end, exposing the head end of the operating table or the patient's head, facilitating patient movement or operations on the patient's head. In this embodiment, sliding the first end of the second crossbar and rotating the first and second crossbars improves the folding and retraction speed of the crossbar assembly, increasing the efficiency of covering or exposing the patient's head. The operation is simple and convenient for medical personnel.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0046] This disclosure provides a pacemaker surgical folding headrest, such as... Figures 1 to 12 As shown, the pacemaker surgical folding headframe includes a mounting assembly 100 and a folding assembly 200. The mounting assembly 100 is used to connect to the head end 310 of the operating table 300. The folding assembly 200 includes an overlap member 210 and two crossbar assemblies 220, which are laterally spaced along the head end 310. Each crossbar assembly 220 includes a first crossbar 221 rotatably connected to the mounting assembly 100 and at least one second crossbar 222. The first crossbar 221 is rotatably connected to the mounting assembly 100 at its first end, and the second crossbar 222 is slidable and rotatable relative to the mounting assembly 100 at its first end. The overlap 210 extends laterally along the head end 310. One end of the overlap 210 is connected to the second end of the first cross bar 221 and / or the second cross bar 222 of a cross bar group 220 away from the mounting assembly 100. The other end of the overlap 210 is connected to the second end of the first cross bar 221 and / or the second cross bar 222 of another cross bar group 220 away from the mounting assembly 100.

[0047] In this optional embodiment, the pacemaker surgery folding headframe includes a mounting assembly 100 and a folding assembly 200. The folding assembly 200 is mounted on the head end 310 of the operating table 300 via the mounting assembly 100. The folding assembly 200 includes an overlap member 210 and two crossbar assemblies 220, which are respectively located on both sides of the head end 310. Each crossbar assembly 220 includes a first crossbar 221 rotatably connected to at least one second crossbar 222. The first end of the second crossbar 222 is slidable and rotatable relative to the mounting assembly 100. Thus, the crossbar assembly 220 can be unfolded or folded by the relative sliding of the first ends of the second crossbars 222.

[0048] The two ends of the lap joint 210 are respectively connected to the second ends of the first cross bar 221 and / or the second cross bar 222 of the two cross bar assemblies 220, and the lap joint 210 extends laterally along the head end 310. The two cross bar assemblies 220 can support the lap joint 210 on the upper side of the patient's head and face. When the cross bar assemblies 220 are unfolded, sterile drapes or other coverings can be draped over the lap joint 210 to cover the patient's head and face. At this time, the first cross bar 221 and the second cross bar 222 are intersected, which can improve the working stability of the cross bar assemblies 220 and improve the support stability of the lap joint 210 and the covering.

[0049] When the patient's head and face need to be exposed during movement or operation, the covering can be removed. The first end of the first crossbar 221 and the first end of the second crossbar 222 can both rotate relative to the mounting assembly 100. After the crossbar assembly 220 is folded, it can rotate relative to the mounting assembly 100 to move the connecting piece 210 away from the area above the head end 310, exposing the head end 310 of the operating table 300 or the patient's head, so as to facilitate patient movement or operation on the patient's head.

[0050] In this embodiment, by sliding the first end of the second crossbar 222 and rotating the first crossbar 221 and the second crossbar 222, the speed of folding and retracting of the crossbar assembly 220 can be improved, thus increasing the efficiency of covering or exposing the patient's head. Moreover, the operation is simple and convenient for medical staff.

[0051] In some alternative embodiments, such as Figure 3 and Figures 6 to 9 As shown, the first end of the second crossbar 222 is capable of sliding relative to the mounting assembly 100 between the first and second positions along the vertical direction of the head end 310.

[0052] When the first end of the second crossbar 222 is in the first position, the crossbar assembly 220 is in the unfolded state. When the first end of the second crossbar 222 is in the second position, the crossbar assembly 220 is in the folded state, and the first ends of the second crossbar 222 and the first ends of the first crossbar 221 can both rotate relative to the mounting assembly 100.

[0053] In this embodiment, when the first end of the second crossbar 222 is in the first position, the crossbar assembly 220 is in an unfolded state to improve the stability of the support for the connector 210 and the shielding. When the first end of the second crossbar 222 is in the second position, the crossbar assembly 220 can be quickly folded, and the first ends of both the second crossbar 222 and the first crossbar 221 can rotate relative to the mounting assembly 100, allowing the connector 210 to move above the head end 310, freeing up more space for easier patient movement and handling. The first end of the second crossbar 222 can slide between the first and second positions, allowing the crossbar assembly 220 to quickly switch between unfolded and folded states as needed, improving the ease of operation of the pacemaker surgery headframe. Medical personnel can quickly adjust the headframe state at different surgical stages to meet different needs.

[0054] Furthermore, the first crossbar 221 and the second crossbar 222 are arranged sequentially along the transverse direction of the head end 310, so that when the crossbar group 220 is in a folded state, the first crossbar 221 and the second crossbar 222 can be arranged side by side, improving the neatness of the crossbar group 220 when it is stored.

[0055] The connector can be mesh-like, plate-like, or other openwork shapes. The connector can be installed at the corresponding position of the crossbar when the second crossbar is in the first position; that is, the connector and the crossbar are detachable. The connector can be removed when the second crossbar moves from the first position to the second position.

[0056] The vertical direction of the head end 310 is the direction perpendicular to the horizontal direction of the head end 310 on the horizontal plane where the head end 310 is located.

[0057] In some alternative embodiments, such as Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 11 As shown, the lap joint 210 includes a plurality of lap rods, including a first lap rod 211 that connects to the second end of the first cross rod 221 in the two cross rod groups 220, and a second lap rod 212 that connects to the second end of the second cross rod 222 in the two cross rod groups 220.

[0058] In this embodiment, the two ends of the first overlapping rod 211 are respectively connected to the second ends of the first cross rod 221 in the two cross rod groups 220, and the two ends of the second overlapping rod 212 are respectively connected to the second ends of the second cross rod 222 in the two cross rod groups 220. In this way, the shielding material can not only be overlapped on the pacemaker surgery folding head frame through the first overlapping rod 211 and the second overlapping rod 212 to improve the overlapping stability of the shielding material, but also maintain a connected state with the cross rod when the second cross rod switches between the first position and the second position, simplifying the use of the pacemaker surgery folding head frame.

[0059] In some alternative embodiments, in any crossbar group 220, the extension length of the crossbar relatively closer to another crossbar group is less than the extension length of the crossbar relatively farther away from another crossbar group.

[0060] In this optional embodiment, when the crossbar group 220 is in a folded state, the extension length of the crossbar that is relatively closer to another crossbar group is less than the extension length of the crossbar that is relatively farther away from another crossbar group. That is, the extension length of the crossbar on the outside is greater than the extension length of the crossbar on the inside. The first overlapping bar 211 and the second overlapping bar 212 can avoid each other so that the first crossbar 221 and the second crossbar 222 can be on the same plane when folded, thereby improving the neatness of the crossbar group 220 when stored.

[0061] Optionally, the crossbar located on the outer side is the first crossbar 221, and the crossbar located on the inner side is the second crossbar 222, that is, the extension length of the first crossbar 221 is greater than the extension length of the second crossbar 222.

[0062] Alternatively, the crossbar located on the inner side is the first crossbar 221, and the crossbar located on the outer side is the second crossbar 222, that is, the extension length of the second crossbar 222 is greater than the extension length of the first crossbar 221.

[0063] In some alternative embodiments, such as Figures 1 to 11 As shown, there is one second crossbar 222, which is rotatably connected to the first crossbar 221.

[0064] Optionally, the middle part of the first cross bar 221 is rotatably connected to the middle part of the second cross bar 222.

[0065] Optionally, such as Figure 10 and Figure 11 As shown, the second cross bar 222 has a handle 223 on the side wall away from the head end 310, so that medical staff can slide or rotate the second cross bar 222 by using the handle 223.

[0066] Optionally, the first crossbar 221 is bent at the position corresponding to the handle 223 to avoid the arm and improve the neatness of the crossbar assembly 220 after folding.

[0067] In some alternative embodiments, such as Figure 12 As shown, there are multiple second crossbars 222, and the multiple second crossbars 222 and the first crossbar 221 form a multi-link crossarm structure.

[0068] In this optional embodiment, multiple second crossbars 222 form a multi-link crossarm structure with the first crossbar 221, which increases the number of crossarms in the crossbar assembly 220 and increases the extension length of the crossbar assembly 220 when deployed to meet the patient's shielding needs. Furthermore, the cross assembly can be positioned along the extension direction of the mounting assembly 100 via the first crossbar 221.

[0069] The first end of at least one second crossbar 222 can connect or abut with the mounting assembly 100 when the crossbar assembly 220 is deployed, thereby improving the stability of the crossbar assembly 220 when it is deployed.

[0070] Optionally, when the crossbar group 220 includes a first crossbar 221 and a plurality of second crossbars 222, the first crossbar 221 is either an end crossbar or a middle crossbar along the unfolding direction of the crossbar group 220.

[0071] Optionally, when there are multiple second crossbars 222, the number of overlapping bars is equal to or less than the sum of the number of first crossbars 221 and second crossbars 222.

[0072] In some alternative embodiments, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the mounting assembly 100 includes a mounting bracket 110 and a support base 120. The mounting bracket 110 is used to connect to the head end 310. Along the transverse direction of the head end 310, the end of the mounting bracket 110 is provided with a first sliding structure 111.

[0073] The support base 120 is provided with a second sliding structure 121 adapted to the first sliding structure 111. The support base 120 is detachably connected to the end of the fixing frame 110 through the first sliding structure 111 and the second sliding structure 121. The first end of the first cross rod 221 is rotatably connected to the support base 120, and the first end of the second cross rod 222 can slide and rotate relative to the support base 120.

[0074] In this optional embodiment, the fixing frame 110 is connected to the head end 310, and the support base 120 and the fixing frame 110 are detachably connected by a matching second sliding structure 121 and a first sliding structure 111, so that the folding assembly 200 connected to the support base 120 can be disposed at the end of the fixing frame 110.

[0075] By setting a compatible second sliding structure 121 and a first sliding structure 111 to facilitate the connection between the support base 120 and the fixing frame 110, the folding assembly 200 can be disassembled and assembled at the head end 310 of the operating table 300, and the speed of disassembling and assembling the folding assembly 200 can be increased. In special circumstances (such as when the folding assembly 200 is contaminated by the patient's vomit), the folding assembly 200 can also be replaced through the second sliding structure 121 and the first sliding structure 111, thereby improving the convenience of operation for medical staff.

[0076] In some alternative embodiments, there are two support seats 120, which are correspondingly arranged at the ends of the fixing frame 110. In this way, along the transverse direction of the head end 310, two support seats 120 are provided at the two ends of the fixing frame 110, and two cross rod assemblies 220 can be respectively provided on both sides of the transverse direction of the head end 310 through the two support seats 120, so as to support the two ends of the connecting piece 210 and improve the stability and reliability of the pacemaker surgery head frame folding operation.

[0077] Optionally, the support base 120 includes a base body 122 and a hinge plate 124 connected to the base body 122. The base body 122 is provided with a sliding limiting groove, the first end of the second cross rod 222 is disposed in the sliding limiting groove, and the pulley can slide and rotate relative to the side wall of the sliding limiting groove. The first end of the first cross rod 221 is rotatably connected to the connecting plate.

[0078] In this embodiment, the first end of the second cross rod 222 can slide and rotate within the sliding limiting groove. The sliding limiting groove can slide and limit the second cross rod 222, reducing the occurrence of excessive sliding or accidental detachment of the second cross rod 222 during use, and improving the stability and safety of the pacemaker surgery head frame during use.

[0079] Optionally, the sliding limiting groove is located on the top wall or side wall of the seat 122. When the sliding limiting groove is located on the side wall of the seat 122, the first end of the second cross rod 222 includes a protrusion that protrudes toward the sliding limiting groove.

[0080] For example, such as Figures 1 to 4As shown, the support base 120 includes a base body 122, a limiting plate 123, and a hinge plate 124 protruding from the upper sidewall of the base body 122. The limiting plate 123 surrounds the edge of the upper sidewall of the base body 122 to limit the second cross rod 222 in the sliding direction. The first end of the first cross rod 221 is rotatably connected to the hinge plate 124. The base body 122 is provided with a second sliding structure 121.

[0081] In this embodiment, the limiting plate 123 is arranged around the upper side wall edge of the seat 122. The limiting plate 123 can limit the second cross rod 222 in the sliding direction to reduce the occurrence of excessive sliding or accidental detachment of the second cross rod 222 during use, thereby improving the stability and safety of the pacemaker surgery head frame.

[0082] The first end of the second crossbar 222 slides and rotates on the upper side wall of the base 122, which facilitates the movement of the second crossbar 222 and reduces the occurrence of sliding displacement or rotational obstruction, thereby improving the reliability and stability of the second crossbar 222's operation. Furthermore, the upper side wall of the base 122 supports the second crossbar 222, simplifying the structure of the base 122 and reducing its production cost.

[0083] The first end of the second cross bar 222 is located on the upper side wall of the seat 122, and the first end of the first cross bar 221 is rotatably connected to the hinge plate 124 protruding from the upper side wall of the seat 122, so that the first cross bar 221 and the second cross bar 222 are located at the same height position, thereby improving the neatness of the cross bar group 220 when folded.

[0084] Optionally, such as Figure 6 and Figure 7 As shown, the hinge plate 124 is located on the side of the head end 310 near the foot end of the operating table 300. Thus, when the crossbar assembly 220 is rotated in the folded state, it can rotate towards the side away from the foot end of the operating table 300, allowing the connecting piece 210, which is connected to the second end of the first crossbar 221 and the second end of the second crossbar 222, to rotate to the outside of the operating table 300, reducing the possibility of the pacemaker surgery headframe obstructing the patient's head and face when folded. Furthermore, the crossbar assembly 220 can also be placed on the upper side wall of the seat 122 when folded, improving the stability of the folding assembly 200 during storage.

[0085] Optionally, the first sliding structure 111 includes a slide rail, and the second sliding structure 121 includes a slide groove adapted to the slide rail, so that the support and the fixing frame can be detachably slidably connected.

[0086] Alternatively, the first sliding structure 111 includes a groove, and the second sliding structure 121 includes a rail adapted to the groove.

[0087] In some alternative embodiments, such as Figure 3 and Figure 4 As shown, one of the compatible second sliding structure 121 and the first sliding structure 111 has a mounting cavity 112 on its side wall, and an elastic limiting member 113 is provided in the mounting cavity 112. The other of the compatible second sliding structure 121 and the first sliding structure 111 has a mounting groove on its side wall.

[0088] When the support base 120 is connected to the fixing frame 110 and the support base 120 is in the preset installation position, the elastic limiting member 113 moves toward the mounting groove so as to be located in the mounting groove.

[0089] In this embodiment, the elastic limiting member 113 is disposed within the mounting cavity 112. When the support base 120 is connected to the fixing frame 110 and is in a preset installation position, it automatically moves towards the mounting groove and is located within the mounting groove. This provides guidance for the connection between the support base 120 and the fixing frame 110, ensuring the support base 120 is installed in the preset position and improving the accuracy of the support base 120's installation position. Furthermore, the elastic limiting member 113's location within the mounting groove restricts the relative movement between the support base 120 and the fixing frame 110, reducing displacement of the support base 120 during use and improving the stability and safety of the pacemaker surgery folding head frame.

[0090] When medical staff disassemble the support 120, they apply force to the support 120. The side wall of the mounting groove and the side wall of the other of the matching second sliding structure 121 and first sliding structure 111 can provide a squeezing force to the elastic limiting member 113, so that the elastic limiting member 113 returns to the mounting cavity 112, releases the limitation, and allows the support 120 and the fixing frame 110 to slide relative to each other.

[0091] Optionally, the elastic limiting member 113 includes a spring and a ball bearing. The spring is disposed in the mounting cavity 112, and one end of the spring is fixedly connected in the mounting cavity 112. The ball bearing is connected to the other end of the spring.

[0092] In this embodiment, the outer surface of the ball bearing is arc-shaped. When the support base 120 is disassembled, this facilitates the application of force to the ball bearing as it moves into the mounting cavity 112, reducing the force required for disassembly by medical personnel and simplifying the operation. When the support base 120 is installed, as it moves to the preset installation position, the ball bearing, under the action of the spring, bounces into the mounting groove and makes a sound upon impact with the inner wall of the groove, indicating to medical personnel that the installation is in place.

[0093] Optionally, when the support 120 is in a preset installation position, the length of the ball within the mounting cavity 112 along the elastic direction of the spring is less than or equal to the radius of the ball.

[0094] For example, such as Figures 5 to 11 As shown, the side wall of the first sliding structure 111 is provided with a mounting cavity 112, and the side wall of the second sliding structure 121 is provided with a mounting cavity 112.

[0095] In some alternative embodiments, such as Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, the fixing frame 110 includes a frame body 114, a locking member 115, and an adjusting member 116. The frame body 114 is used to fit onto the outer wall of the head end 310. Along the transverse direction of the head end 310, the two ends of the frame body 114 are provided with first sliding structures 111. The locking member 115 is located on the side of the frame body 114 facing the head end 310. One end of the adjusting member 116 passes through the frame body 114, and the adjusting member 116 is threadedly connected to the frame body 114. The adjusting member 116 is used to drive the locking member 115 to move towards the head end 310, so as to clamp the head end 310 between the locking member 115 and the frame body 114.

[0096] In this optional embodiment, the frame 114 is fitted onto the outer wall of the head end 310, allowing the frame 114 to be installed on the head end 310 of the operating table 300. A locking member 115 is located on the side of the frame 114 facing the head end 310. The threaded connection between the adjusting member 116 and the frame 114 allows medical personnel to move the locking member 115 towards the head end 310 by turning the adjusting member 116, thereby clamping the head end 310 between the locking member 115 and the frame 114. Alternatively, the locking member 115 can be moved away from the head end 310 to unlock the frame 114, thus disassembling the fixing frame 110.

[0097] Optionally, one end of the adjusting member 116 is connected to or abuts against the locking member 115.

[0098] Optionally, along the transverse direction of the head end 310, the two ends of the frame 114 are respectively provided with a first sliding structure 111.

[0099] In this embodiment, when installing the pacemaker surgical folding head frame, the frame body 114 can first be fitted onto the outer wall of the head end 310, and the head end 310 can be clamped between the locking member 115 and the frame body 114 by screwing the adjusting member 116 to fix the frame body 110. Then, the support base 120 is connected to the frame body 114 through the matching second sliding structure 121 and first sliding structure 111. When the support base 120 moves to the preset installation position, the elastic limiting member 113 can be located in the installation groove to position and limit the support base 120, and the installation can be indicated to medical staff by sound. After the support base 120 is installed, the crossbar assembly 220 connected to the support base 120 can be rotated to make it vertically positioned. Then, the first end of the second crossbar 222 can be slid to allow the crossbar assembly 220 to unfold. The first overlapping rod 211 and the second overlapping rod 212 are spaced apart above the patient's head and face so that a covering can be attached to the first overlapping rod 211 and the second overlapping rod 212 to cover the patient's head and face.

[0100] During or after surgery, when it is necessary to move the patient's head and face, the first end of the second crossbar 222 can be slid directly to fold the crossbar assembly 220. Then, the crossbar assembly 220 can be rotated to move the folding component 200 completely to the upper outside of the patient's head and face, thereby facilitating the operation. This improves the efficiency of moving the pacemaker away from the upper part of the patient's head and face during pacemaker surgery, and is simple and convenient for medical staff to operate.

[0101] Alternatively, the support base 120 can be pulled out directly to separate the support base 120 from the fixing frame 110, thereby disassembling the folding rod assembly and moving the folding rod assembly completely to the outside of the upper side of the patient's head and face, so as to perform operations on the patient's head and face.
