Description

Technical Field

[0001] This invention relates to a fixation device, and more particularly to a fixation device for puncture in anesthesiology. Background Technology

[0002] Anesthesia is the use of drugs or other methods to temporarily eliminate sensation in a patient's entire body or part of their body, thereby achieving painlessness. The purpose of anesthesia is to relieve patient pain during surgery, ensure patient safety, and create favorable conditions for the procedure. Anesthesiology has now become a specialized and independent discipline within clinical medicine.

[0003] During surgery, doctors need to manually operate the puncture needle to puncture specific sites. In order to reduce the chance of puncture errors, doctors are usually required to concentrate and hold the puncture needle steadily. The operation requires a certain level of experience from the doctor. However, for interns, due to lack of experience, interns often have trembling hands due to nervousness, making it difficult to maintain stability during puncture, which leads to deviations in the puncture position. Summary of the Invention

[0004] To overcome the drawback that interns often experience hand tremors due to nervousness, making it difficult to maintain stability during punctures and leading to deviations in the puncture position, the purpose of this invention is to provide a fixation device for anesthesiology punctures that can fix the puncture position.

[0005] The technical solution is as follows: A fixation device for puncture in anesthesiology includes a bed, a guide rail, and a moving platform. The guide rail is connected to the right side of the bed, and the moving platform is located on the right side of the bed. The device also includes a puncture table, a fixation table, a stabilizing mechanism, and a fixing mechanism. The puncture table is connected to the top of the moving platform. Fixation tables are located on both the front and rear sides of the puncture table. The fixation tables are equipped with a stabilizing mechanism for keeping the moving platform stable and a fixing mechanism for fixing the puncture table.

[0006] As a further preferred embodiment, the hospital bed is equipped with casters at all four corners of its bottom, which are used to move the hospital bed.

[0007] As a further preferred option, the stabilizing mechanism includes a rotating shaft, a knob, a threaded sleeve, and casters. The rotating shaft is rotatably connected to the fixed platform, and a knob is connected to the upper end of the rotating shaft. The front and rear of the moving platform are both connected to threaded sleeves by threads, and the rotating shaft and the threaded sleeves are snapped together. Casters are installed at the four corners of the bottom of the moving platform.

[0008] As a further preferred embodiment, the fixing mechanism includes a cover plate, gears, push blocks, wedge blocks, a first spring, a pressure block, and a second spring. Two gears are connected to the rotating shaft, arranged vertically. Cover plates are connected to both the upper and lower sides of the fixing platform. Push blocks are slidably connected between the upper and lower cover plates and the fixing platform. The push blocks have teeth on the side near the gears. The push blocks on both the upper and lower sides mesh with their adjacent gears through the teeth. Grooves are opened on both the upper and lower sides of the left side of the fixing platform. Wedge blocks are slidably connected in the grooves on both the upper and lower sides of the left side of the fixing platform. After the push blocks move, they will contact the wedge blocks. A first spring is connected between the wedge blocks and the fixing platform. Pressure blocks are slidably connected to the sides of the upper and lower wedge blocks that are close to each other. The pressure blocks contact the guide rail. A second spring is connected between the wedge blocks and the pressure blocks.

[0009] As a further preferred embodiment, it also includes a locking block, a third spring, and a first triangular block. The locking blocks are slidably connected to both the upper and lower sides of the left side of the fixed platform. The locking blocks will contact the guide rail. The third spring is connected between the locking blocks and the fixed platform. The first triangular block is connected to the locking blocks.

[0010] As a further preferred embodiment, it also includes a top block, a stop bar, a fourth spring, a hook bar, a return spring, and a second triangular block. Two top blocks are slidably connected to both the upper and lower sides of the fixed platform. A fourth spring connects the fixed platform to the top blocks. The two top blocks are arranged front to back, and a stop bar connects between the two top blocks. Hook bars are slidably connected to both the upper and lower sides of the fixed platform. A return spring connects the hook bars to the fixed platform. A second triangular block is connected to the lower part of the hook bars. The first triangular block contacts the second triangular block. After the stop bar and the top blocks move, they will contact the hook bars. When the push block moves to the left, it will drive the top blocks and the stop bar to move to the left. After the top blocks contact the hook bars, they will compress the fourth spring, causing the top blocks and the stop bars on the upper and lower sides to move closer to each other. When the top blocks and the stop bars pass the hook bars, the top blocks and the stop bars move away from each other under the action of the fourth spring. The hook bars can hook onto the stop bars.

[0011] As a further preferred option, it also includes safety straps, a first buckle, and a second buckle. Multiple safety strap devices are evenly spaced on the left side of the bed, and the safety straps of the safety strap devices are connected to the first buckle. The right side of the bed is connected to the second buckle, and the first buckle and the second buckle are engaged.

[0012] As a further preferred option, a limiter is also included, which is rotatably connected to the safety harness. When the limiter is rotated, it will lock the safety harness of the safety harness.

[0013] The present invention has the following advantages: 1. The present invention fixes the puncture device on the puncture table, moves the threaded sleeve downward to contact the ground, fixes the moving table, and moves the push block to the left to contact and squeeze the wedge block, the second spring and the pressure block, so that the pressure blocks on the upper and lower sides move closer to each other, clamping the guide rail, so that the fixed table is fixed on the guide rail. The puncture position is fixed by the puncture table. After the puncture position is fixed, the puncture operation is performed, which can stably perform the puncture and reduce the doctor's error rate.

[0014] 2. This invention uses the first triangular blocks on the upper and lower sides to cross the guide rail and lock it in place, preventing the fixed platform from moving to the right and further stabilizing the puncture platform. The second triangular block moves to the right and squeezes the first triangular block, causing the upper and lower first triangular blocks to move to the side away from each other. The first triangular block no longer locks the guide rail, thus replacing manual removal of the first triangular block. The operation is simple and convenient. Attached Figure Description

Detailed Implementation

[0026] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0027] Example 1: A fixation device for puncture in anesthesiology, such as... Figures 1-4 As shown, the device includes a hospital bed 1, a guide rail 2, a moving platform 3, a puncture table 4, a fixed platform 5, a stabilizing mechanism, and a fixing mechanism. The right side of the hospital bed 1 is connected to the guide rail 2. The four corners of the bottom of the hospital bed 1 are equipped with moving wheels for moving the hospital bed 1. The moving platform 3 is located on the right side of the hospital bed 1. The top of the moving platform 3 is connected to the puncture table 4. The puncture table 4 is used to install medical instruments for puncture. Fixed platforms 5 are located on both the front and rear sides of the puncture table 4. The fixed platforms 5 are used to keep the puncture table 4 stable. The fixed platforms 5 are equipped with a stabilizing mechanism and a fixing mechanism. The stabilizing mechanism is used to keep the moving platform 3 stable, and the fixing mechanism is used to fix the puncture table 4.

[0028] like Figures 1-3 As shown, the stabilizing mechanism includes a rotating shaft 51, a knob 52, a threaded sleeve 53, and casters 54. The rotating shaft 51 is rotatably connected to the fixed platform 5, and the knob 52 is connected to the upper end of the rotating shaft 51. Rotating the knob 52 will drive the rotating shaft 51 to rotate. The front and rear of the moving platform 3 are both connected to the threaded sleeve 53 by threads. The rotating shaft 51 and the threaded sleeve 53 are engaged. Casters 54 are installed at the four corners of the bottom of the moving platform 3 to facilitate the movement of the moving platform 3.

[0029] like Figures 1-4As shown, the fixing mechanism includes a cover plate 6, a gear 61, a push block 62, a wedge block 63, a first spring 64, a pressure block 65, and a second spring 66. Two gears 61 are mounted on the rotating shaft 51. Rotation of the rotating shaft 51 will drive the upper and lower gears to rotate. The upper and lower sides of the fixing platform 5 are connected to the cover plate 6. The upper and lower cover plates 6 are slidably connected to the fixing platform 5 with the push block 62. The push block 62 has teeth on the side near the gear 61. The push block 62 meshes with the adjacent gear 61 through the teeth. The fixed platform 5 has grooves on both the upper and lower sides of its left side. Wedge blocks 63 are slidably connected in the grooves on both the upper and lower sides of the left side of the fixed platform 5. After the push block 62 moves, it will contact and squeeze the wedge blocks 63. A first spring 64 is connected between the wedge blocks 63 and the fixed platform 5. A pressure block 65 is slidably connected on the side of the upper and lower wedge blocks 63 that are close to each other. The pressure block 65 contacts the guide rail 2. A second spring 66 is connected between the wedge blocks 63 and the pressure block 65. The pressure blocks 65 on the upper and lower sides will clamp the guide rail 2.

[0030] In use, when a doctor performs a puncture on a patient, the patient lies flat on the bed 1, the moving platform 3 is moved to the appropriate puncture position, the puncture device is fixed on the puncture table 4, and the knob 52 is turned. The rotation of the knob 52 will drive the rotating shaft 51 to rotate, and the rotation of the rotating shaft 51 will drive the threaded sleeve 53 to rotate. Since the threaded sleeve 53 is connected to the moving platform 3 by threads, the threaded sleeve 53 will move downward when it rotates, and the threaded sleeve 53 will contact the ground, thereby fixing the moving platform 3. At the same time, when the rotating shaft 51 rotates, it will drive the gear 61 to rotate. The rotation of the gear 61 will drive the push block 62 to move to the left through the teeth. The push block 62 will contact and squeeze the wedge block 63, the second spring 66 and the pressure block 65, so that the pressure blocks 65 on the upper and lower sides move closer to each other, clamping the guide rail 2, so that the fixed platform 5 is fixed on the guide rail 2, and the puncture table 4 is fixed. At this time, the puncture can be performed stably.

[0031] Example 2: Based on Example 1, such as Figure 5 As shown, it also includes a locking block 71, a third spring 72, and a first triangular block 73. The locking blocks 71 are slidably connected to the upper and lower sides of the left side of the fixed platform 5. The locking blocks 71 will contact the guide rail 2. The third spring 72 is connected between the locking blocks 71 and the fixed platform 5. The first triangular block 73 is connected to the locking blocks 71. When the fixed platform 5 is pushed to the left, the first triangular blocks 73 on the upper and lower sides will cross the guide rail 2 and lock it, preventing the fixed platform 5 from moving to the right, and further stabilizing the puncture table 4.

[0032] like Figures 5-7As shown, it also includes a top block 8, a stop bar 801, a fourth spring 81, a hook bar 82, a return spring 83, and a second triangular block 84. Two top blocks 8 are slidably connected to both the upper and lower sides of the fixed platform 5. A fourth spring 81 connects the fixed platform 5 to the top blocks 8. The two top blocks 8 are arranged front to back, and a stop bar 801 connects them. Hook bars 82 are slidably connected to both the upper and lower sides of the fixed platform 5. A return spring 83 connects the hook bar 82 to the fixed platform 5. A second triangular block 84 is connected to the lower part of the hook bar 82. The first triangular block... When 73 contacts the second triangular block 84, the stop bar 801 and the top block 8 will both contact the hook bar 82 after moving. When the push block 62 moves to the left, it will drive the top block 8 and the stop bar 801 to move to the left. After the top block 8 contacts the hook bar 82, it will compress the fourth spring 81, causing the top blocks 8 and the stop bar 801 on the upper and lower sides to move closer to each other. When the top block 8 and the stop bar 801 pass the hook bar 82, the top block 8 and the stop bar 801 will move away from each other under the action of the elastic force of the fourth spring 81. The hook bar 82 can hook the stop bar 801.

[0033] After the puncture is completed, turning the knob 52 in the opposite direction will cause the push block 62, the stop bar 801 and the hook bar 82 to move to the right. The movement of the hook bar 82 to the right will cause the second triangular block 84 to move to the right. The movement of the second triangular block 84 to the right will squeeze the first triangular block 73, causing the upper and lower first triangular blocks 73 to move to the side away from each other. The first triangular block 73 will no longer be stuck in the guide rail 2 and will automatically release. There is no need to manually remove the first triangular block 73, making the operation convenient and quick.

[0034] like Figures 8-10 As shown, it also includes a safety strap, a first buckle 91 and a second buckle 92. Multiple safety strap devices 9 are evenly spaced on the left side of the bed 1. The safety strap of the safety strap device 9 is connected to the first buckle 91. The right side of the bed 1 is connected to the second buckle 92. The first buckle 91 and the second buckle 92 are engaged. During puncture, the safety strap of the safety strap device 9 can be used to tie the patient to prevent the patient from rotating and changing the puncture position.

[0035] like Figure 8 and Figure 9 As shown, it also includes a limiter 10. The limiter 10 is rotatably connected to the safety strap 9. The friction between the safety strap 9 and the limiter 10 is relatively large. The limiter 10 needs to be rotated with force. After the limiter 10 rotates, it will lock the safety strap of the safety strap 9, so that the safety strap will no longer be pulled out. The safety strap of the safety strap 9 is in a taut state, stabilizing the patient.
