Description

Technical Field

[0001] This invention relates to the field of facial support technology, and more specifically to an adjustable facial support frame for prone surgery. Background Technology

[0002] Prone position surgery refers to a surgical position in which the patient lies prone on the operating table. This position is usually used for back or neck surgeries. Some common prone position surgeries include cervical spine surgery, back surgery (such as spinal surgery), and posterior fossa surgery. During prone position surgery, the patient lies face down on the operating table, and the bed supports the patient's body. At the same time, an opening is made at one end of the operating table to allow the operator to insert their head for positioning.

[0003] In existing prone surgery procedures, the facial support for patients is usually fixed and cannot be adjusted according to different patients. Furthermore, the location of the facial support is usually fixed, which can cause pressure sores when the patient's face is in contact with the support device for a long time, causing harm to the patient and making it difficult for them to live a good life after surgery. Summary of the Invention

[0004] The purpose of this invention is to provide alternating support for the patient's face with the first set of rubber airbags and the second set of rubber airbags, thereby preventing pressure sores from forming when the same part of the patient's face is in prolonged contact with the support device. This solves the problem in the prior art where pressure sores are formed when the patient's face is in prolonged contact with the support device, causing harm to the patient and negatively impacting their postoperative life.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable facial support frame for prone surgery, comprising a fastening mounting frame, a support assembly, and a locking assembly, wherein two sets of the support assembly are provided on one side of the fastening mounting frame;

[0006] The support assembly includes a support arc plate, a sliding arc block, a mounting arc block, and inflatable rubber airbags. The sliding arc block is fixedly connected to the fastening mounting bracket, and the support arc plate is slidably connected to the sliding arc block. An arc-shaped notch is provided on the side of the support arc plate. The mounting arc block is located at the arc-shaped notch and is fixedly connected to the top surface of the support arc plate. A support mounting groove is provided on the top surface of the mounting arc block, and several inflatable rubber airbags are provided in the groove of the support mounting groove.

[0007] When the two supporting arc plates move and come into contact, the outline formed by the two arc-shaped notches is similar to the outline of the human face. The inflatable rubber airbag is divided into a first group of rubber airbags and a second group of rubber airbags. When the first group of rubber airbags moves out of the support mounting groove, the first group of rubber airbags can be inflated. The second group of rubber airbags is located in the support mounting groove. When the first group of rubber airbags moves into the support mounting groove, the second group of rubber airbags can move out of the support mounting groove and inflate.

[0008] The locking component includes a locking compression block, which is slidably connected to the supporting arc plate. The locking compression block can move to contact and compress the sliding arc block. Only after the locking compression block contacts and compresses the sliding arc block can the inflatable rubber airbag move.

[0009] Furthermore, the support assembly also includes a lifting square tube, a first connecting plate, a second connecting plate, a lifting movable plate, and a rotating screw. The bottom end of the inflatable rubber airbag is fixedly connected to the lifting square tube. The lifting square tube corresponding to the first set of rubber airbags slides through the mounting arc block and the supporting arc plate and is fixedly connected to the first connecting plate. The lifting square tube corresponding to the second set of rubber airbags slides through the mounting arc block, the supporting arc plate, and the first connecting plate and is fixedly connected to the second connecting plate. A rotating mounting block is fixedly installed on the side of the supporting arc plate. The rotating screw is rotatably installed on the bottom surface of the rotating mounting block. Two lifting movable plates are threaded on the rotating screw. The two lifting movable plates are fixedly connected to the first connecting plate and the second connecting plate, respectively.

[0010] Furthermore, the support assembly also includes a control electric actuator, a movable rack, and a rotating gear ring. A fixed mounting plate is fixedly installed on the bottom surface of the support arc plate. The control electric actuator is fixedly connected to the fixed mounting plate. The rotating gear ring is fixedly sleeved on the rotating lead screw. The movable rack is fixedly connected to the output end of the control electric actuator. When the movable rack moves, it can mesh with the rotating gear ring.

[0011] Furthermore, the locking assembly also includes a rack mounting plate, a locking rack, a rotating gear, a spring, and a locking connecting rod. The rack mounting plate is fixedly mounted on the side of the fixed mounting plate, the locking rack is slidably mounted on the bottom surface of the rack mounting plate, the rotating gear is rotatably mounted on the bottom surface of the rack mounting plate, the rotating gear meshes with the locking rack, the rotating shaft of the rotating gear passes through the rack mounting plate, the spring is fixedly sleeved on the rotating shaft, the spring is fixedly connected to the rack mounting plate, one end of the locking connecting rod is fixedly connected to the locking rack, and the other end is fixedly connected to the locking compression block.

[0012] Furthermore, the locking assembly also includes a rotating stop bar, a rotating connecting rod, and a rotating mounting rod. A stop bar mounting block is fixedly installed on the bottom surface of the supporting arc plate. One end of the rotating stop bar is rotatably installed on the bottom surface of the stop bar mounting block. The rotating mounting rod is fixedly installed on the bottom surfaces of both the rotating stop bar and the rotating gear. The two ends of the rotating connecting rod are respectively rotatably sleeved on the two rotating mounting rods.

[0013] Furthermore, the support assembly also includes gas supply pipes, with one end of each of the two gas supply pipes passing through the lifting and moving plate and being fixedly connected to the first connecting plate and the second connecting plate, respectively.

[0014] Furthermore, the rotating lead screw is a bidirectional threaded rod, and when the rotating lead screw rotates, the two lifting moving plates move towards each other or away from each other.

[0015] Furthermore, the bottom surface of the rotating stop bar is at the same height as the bottom surface of the moving rack, so that when the moving rack moves, it can squeeze the rotating stop bar, causing the rotating stop bar to rotate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] During prone surgery, the first set of rubber airbags inflates after being removed from the support mounting slot, and the patient's head moves onto the fastening frame. The inflated first set of rubber airbags then provides contact support to the patient's face. During the surgery, as the first set of rubber airbags moves into the support mounting slot, the second set of rubber airbags is removed from the slot and inflates, providing support to the patient's face. After a period of time, when the second set of rubber airbags moves into the support mounting slot, the first set of rubber airbags is removed again to support the patient's face. The contact areas between the first and second sets of rubber airbags and the patient's face do not overlap. During the surgery, the first and second sets of rubber airbags alternately support the patient's face, preventing pressure sores from developing due to prolonged contact between the same area of ​​the face and the support device, thus reducing harm to the patient.

[0018] After the position of the supporting arc plate is adjusted, the control electric actuator drives the moving rack to move closer to the rotating gear ring. During the movement of the moving rack, it presses against the rotating stop rod and causes the rotating stop rod to rotate. The rotating stop rod drives the rotating gear to rotate through the rotating connecting rod. The rotation of the rotating gear compresses the spring. The rotation of the rotating gear drives the locking rack to move. The movement of the locking rack drives the locking connecting rod to move. The movement of the locking connecting rod drives the locking compression block to move. An elastic block is fixedly installed at one end of the locking compression block. The locking compression block drives the elastic block to move and press against the sliding arc block. The compression of the elastic block and the sliding arc block increases friction, thus fixing the position of the supporting arc plate. After the moving rack presses against the stop rod, it meshes with the rotating gear ring. This can automatically fix the supporting arc plate before controlling the raising and lowering of the inflatable rubber airbag, preventing the supporting arc plate from being displaced by external force and preventing the inflatable rubber airbag from failing to perform its supporting function, thus improving the applicability of the device.

[0033] As attached Figure 1 To be continued Figure 10 As shown:

[0034] Example 1:

[0035] The present invention provides an adjustable facial support frame for prone surgery, including a fastening mounting frame 1, a support component 2 and a locking component 3, wherein two sets of support components 2 are provided on one side of the fastening mounting frame 1;

[0036] The support assembly 2 includes a support arc plate 201, a sliding arc block 202, a mounting arc block 203, and an inflatable rubber airbag 204. The sliding arc block 202 is fixedly connected to the fastening mounting bracket 1, and the support arc plate 201 is slidably connected to the sliding arc block 202. The side of the support arc plate 201 has an arc-shaped notch, and the mounting arc block 203 is located at the arc-shaped notch and is fixedly connected to the top surface of the support arc plate 201. The top surface of the mounting arc block 203 has a support mounting groove 205, and a plurality of inflatable rubber airbags 204 are arranged in the groove of the support mounting groove 205.

[0037] When the two supporting arc plates 201 come into contact, the outline formed by the two arc-shaped notches is similar to the outline of the human face. The inflatable rubber airbags 204 are divided into a first group of rubber airbags 2041 and a second group of rubber airbags 2042. When the first group of rubber airbags 2041 moves out of the support mounting groove 205, the first group of rubber airbags 2041 can be inflated. The second group of rubber airbags 2042 is located in the support mounting groove 205. When the first group of rubber airbags 2041 moves into the support mounting groove 205, the second group of rubber airbags 2042 can move out of the support mounting groove 205 and inflate.

[0038] The locking component 3 includes a locking compression block 301, which is slidably connected to the support arc plate 201. The locking compression block 301 can move to contact and compress the sliding arc block 202. Only after the locking compression block 301 contacts and compresses the sliding arc block 202 can the inflatable rubber airbag 204 move.

[0039] Before use, the support arc plate 201 is moved according to the patient's facial contour so that the contour formed by the two arc-shaped notches resembles the patient's facial contour. The locking compression block 301 is moved and contacts the sliding arc block 202 to compress and fix the position of the support arc plate 201. During prone surgery, the first set of rubber airbags 2041 is inflated after being removed from the support mounting groove 205. The patient's head is moved onto the fastening mounting frame 1, and the inflated first set of rubber airbags 2041 provides contact support for the patient's face. During the surgery, while the first set of rubber airbags 2041 moves into the support mounting groove 205, the second set of rubber airbags 2042 moves out of the support mounting groove 205. After inflation, the second set of rubber airbags 2042 supports the patient's face. After a period of time, when the second set of rubber airbags 2042 moves into the support mounting groove 205, the first set of rubber airbags 2041 moves out of the support mounting groove 205 to support the patient's face again. The contact points between the first set of rubber airbags 2041 and the patient's face and the contact points between the second set of rubber airbags 2042 and the patient's face do not overlap. During the operation, the first set of rubber airbags 2041 and the second set of rubber airbags 2042 alternately support the patient's face to prevent pressure sores from being caused by prolonged contact between the same part of the patient's face and the support device, thereby reducing harm to the patient.

[0040] Example 2:

[0041] This embodiment is basically the same as the previous embodiment, except that the support component 2 also includes a lifting square tube 206, a first connecting plate 207, a second connecting plate 208, a lifting moving plate 209, and a rotating screw 210. The bottom end of the inflatable rubber airbag 204 is fixedly connected to the lifting square tube 206. The lifting square tube 206 corresponding to the first set of rubber airbags 2041 slides through the mounting arc block 203 and the supporting arc plate 201 and is fixedly connected to the first connecting plate 207. The lifting square tube 206 corresponding to the second set of rubber airbags 2042 slides through the mounting arc block 203, the supporting arc plate 201 and the first connecting plate 207 and is fixedly connected to the second connecting plate 208. A rotating mounting block is fixedly installed on the side of the supporting arc plate 201. The rotating screw 210 is rotatably installed on the bottom surface of the rotating mounting block. Two lifting moving plates 209 are threaded on the rotating screw 210. The two lifting moving plates 209 are fixedly connected to the first connecting plate 207 and the second connecting plate 208, respectively.

[0042] The support assembly 2 also includes a control electric actuator 211, a movable rack 212, and a rotating gear ring 213. A fixed mounting plate is fixedly installed on the bottom surface of the support arc plate 201. The control electric actuator 211 is fixedly connected to the fixed mounting plate. The rotating gear ring 213 is fixedly sleeved on the rotating lead screw 210. The movable rack 212 is fixedly connected to the output end of the control electric actuator 211. When the movable rack 212 moves, it can mesh with the rotating gear ring 213.

[0043] The support assembly 2 also includes gas supply pipes 214. One end of each gas supply pipe 214 passes through the lifting and moving plate 209 and is fixedly connected to the first connecting plate 207 and the second connecting plate 208 respectively. The rotating screw 210 is a bidirectional threaded rod. When the rotating screw 210 rotates, the two lifting and moving plates 209 move towards each other or away from each other.

[0044] In use, the control electric actuator 211 drives the moving rack 212 to move. During the movement of the moving rack 212, it meshes with the rotating gear ring 213 and drives the rotating gear ring 213 to rotate. The rotation of the rotating gear ring 213 drives the rotating screw 210 to rotate. The rotation of the rotating screw 210 drives the two lifting moving plates 209 to move in opposite directions. The upper lifting moving plate 209 drives the first connecting plate 207 to move upward. The first connecting plate 207 drives the first set of rubber airbags 2041 to move upward out of the support mounting groove 205 through the lifting square tube 206. The air supply pipe 214 corresponding to the first set of rubber airbags 2041 inflates the first set of rubber airbags 2041 through the lifting square tube 206, causing the first set of rubber airbags 2041 to expand. The lower lifting moving plate 209 drives the second connecting plate 208 to move downward. The second connecting plate 208 drives the second connecting plate 208 to move downward through the lifting square tube 206. The second set of rubber airbags 2042 moves downward into the support mounting groove 205. When the rotating screw 210 rotates and drives the two lifting moving plates 209 to move towards each other, the upper lifting moving plate 209 drives the first connecting plate 207 to move downward. The first connecting plate 207 drives the first set of rubber airbags 2041 to move downward into the support mounting groove 205 and deflate and contract through the lifting square tube 206. The lower lifting moving plate 209 drives the second connecting plate 208 to move upward. The second connecting plate 208 drives the second set of rubber airbags 2042 to move upward out of the support mounting groove 205 through the lifting square tube 206. After the second set of rubber airbags 2042 moves out of the support mounting groove 205, the air supply pipe 214 corresponding to the second set of rubber airbags 2042 inflates the second set of rubber airbags 2042 through the lifting square tube 206, causing the second set of rubber airbags 2042 to inflate.

[0045] Example 3:

[0046] This embodiment is basically the same as the previous embodiment, except that the locking assembly 3 also includes a rack mounting plate 302, a locking rack 303, a rotating gear 304, a spring 305, and a locking connecting rod 306. The rack mounting plate 302 is fixedly mounted on the side of the fixed mounting plate, the locking rack 303 is slidably mounted on the bottom surface of the rack mounting plate 302, the rotating gear 304 is rotatably mounted on the bottom surface of the rack mounting plate 302, the rotating gear 304 meshes with the locking rack 303, the rotating shaft of the rotating gear 304 passes through the rack mounting plate 302, the spring 305 is fixedly sleeved on the rotating shaft, the spring 305 is fixedly connected to the rack mounting plate 302, one end of the locking connecting rod 306 is fixedly connected to the locking rack 303, and the other end is fixedly connected to the locking pressing block 301.

[0047] The locking assembly 3 also includes a rotating stop bar 307, a rotating connecting rod 308, and a rotating mounting rod 309. A stop bar mounting block is fixedly installed on the bottom surface of the supporting arc plate 201. One end of the rotating stop bar 307 is rotatably installed on the bottom surface of the stop bar mounting block. Rotating mounting rods 309 are fixedly installed on the bottom surfaces of both the rotating stop bar 307 and the rotating gear 304. The two ends of the rotating connecting rod 308 are respectively rotatably sleeved on the two rotating mounting rods 309. The bottom surface of the rotating stop bar 307 is at the same height as the bottom surface of the moving rack 212. When the moving rack 212 moves, it can squeeze the rotating stop bar 307, causing the rotating stop bar 307 to rotate.

[0048] The sliding installations used in this invention are all interference fits, and the slidingly installed parts can only move under the action of external force;

[0049] After the position of the supporting arc plate 201 is adjusted, the control electric actuator 211 drives the moving rack 212 to move closer to the rotating gear ring 213. During the movement of the moving rack 212, it presses against the rotating stop rod 307 and causes the rotating stop rod 307 to rotate. The rotating stop rod 307 drives the rotating gear 304 to rotate through the rotating connecting rod 308. The rotation of the rotating gear 304 compresses the spring 305. The rotation of the rotating gear 304 drives the locking rack 303 to move. The movement of the locking rack 303 drives the locking connecting rod 306 to move. The movement of the locking connecting rod 306 causes the locking compression. When block 301 moves, a locking compression block 301 is fixedly installed with an elastic block at one end. The locking compression block 301 drives the elastic block to move and compress the sliding arc block 202. The compression of the elastic block and the sliding arc block 202 increases friction, fixing the position of the supporting arc plate 201. After the moving rack 212 compresses the stop bar, it meshes with the rotating gear ring 213. This allows the supporting arc plate 201 to be automatically fixed before the inflatable rubber airbag 204 is raised or lowered, preventing the supporting arc plate 201 from being displaced by external force and thus preventing the inflatable rubber airbag 204 from completing its support work, thereby improving the applicability of the device.

[0050] Working principle:

[0051] Before use, the support arc plate 201 is moved according to the patient's facial contour so that the contour formed by the two arc-shaped notches resembles the patient's facial contour. The electric actuator 211 drives the moving rack 212 to move. During the movement of the moving rack 212, it presses the rotating stop rod 307 and causes the rotating stop rod 307 to rotate. The rotating stop rod 307 drives the rotating gear 304 to rotate through the rotating connecting rod 308. The rotation of the rotating gear 304 drives the locking rack 303 to move. The movement of the locking rack 303 drives the locking connecting rod 306 to move. The movement of the locking connecting rod 306 drives the locking compression block to move. 301 moves and locks the compression block 301. One end of the compression block 301 is fixedly installed with an elastic block. The compression block 301 drives the elastic block to move and compress the sliding arc block 202. The compression of the elastic block and the sliding arc block 202 can increase friction and fix the position of the support arc plate 201. After the moving rack 212 compresses the stop bar, it meshes with the rotating gear ring 213. It can automatically fix the support arc plate 201 before controlling the lifting and lowering of the inflatable rubber airbag 204, preventing the support arc plate 201 from being displaced by external force, so that the inflatable rubber airbag 204 cannot complete the support work and improves the applicability of the device.

[0052] During prone surgery, the moving rack 212 meshes with the rotating gear ring 213 during its movement, driving the rotating gear ring 213 to rotate. The rotation of the rotating gear ring 213 drives the rotating screw 210 to rotate, and the rotation of the rotating screw 210 drives the two lifting moving plates 209 to move in opposite directions. The upper lifting moving plate 209 drives the first connecting plate 207 to move upward. The first connecting plate 207 drives the first set of rubber airbags 2041 to move upward out of the support mounting groove 205 through the lifting square tube 206. The air supply pipe 214 corresponding to the first set of rubber airbags 2041 supplies air to the second set of rubber airbags 2041 through the lifting square tube 206. A set of rubber airbags 2041 is inflated, causing the first set of rubber airbags 2041 to expand. The lower lifting moving plate 209 drives the second connecting plate 208 to move downwards. The second connecting plate 208, through the lifting square tube 206, drives the second set of rubber airbags 2042 downwards into the support mounting groove 205. The patient's head moves onto the fastening mounting frame 1, and the inflated first set of rubber airbags 2041 provides contact support for the patient's face. During the operation, when the rotating screw 210 rotates and drives the two lifting moving plates 209 to move towards each other, the upper lifting moving plate 209 drives... The first connecting plate 207 moves downward, and through the lifting square tube 206, it drives the first set of rubber airbags 2041 to move downward into the support mounting groove 205 and deflate. The lower lifting moving plate 209 drives the second connecting plate 208 to move upward, and through the lifting square tube 206, it drives the second set of rubber airbags 2042 to move upward out of the support mounting groove 205. Once the second set of rubber airbags 2042 is out of the support mounting groove 205, the corresponding air supply pipe 214 supplies air to the second set of rubber airbags 2042 through the lifting square tube 206. Inflate the second set of rubber airbags 2042. After a period of time, when the second set of rubber airbags 2042 moves into the support mounting groove 205, the first set of rubber airbags 2041 moves out of the support mounting groove 205 again to support the patient's face. The contact points between the first set of rubber airbags 2041 and the patient's face and the contact points between the second set of rubber airbags 2042 and the patient's face do not overlap. During the operation, the support points on the patient's face are constantly changing to prevent the same part of the patient's face from being in contact with the support device for a long time, thus preventing pressure sores and reducing harm to the patient.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
