Description

Technical Field

[0001] This invention belongs to the field of microinjection technology, and particularly relates to an adjustable-angle handheld microinjection auxiliary device. Background Technology

[0002] A handheld microinjection aid is a device used to assist in microinjection operations. It is mainly used for precise injection of tiny targets such as cells and embryos in laboratory or field environments. Its core function is to improve operational stability and make up for the shortcomings of traditional microinjection systems in terms of mobility or flexibility. At the same time, the device sacrifices some precision for portability, making it suitable for scenarios that require flexible operating environments.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing handheld microinjection aids:

[0004] 1. The process of adjusting the injection angle of the syringe is relatively cumbersome, resulting in low injection efficiency. It is inconvenient to add angle adjustment measures to the device to quickly adjust the device angle.

[0005] 2. The syringe is directly fixed to the device, which makes it difficult to adjust the length of the syringe extension. It is inconvenient to add positioning measures to the device to position the length of the syringe extension before fixing it. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides an adjustable-angle microinjection handheld auxiliary device. This addresses the issues of cumbersome injection angle adjustment processes in existing syringes, resulting in low injection efficiency, inconvenience in adding angle adjustment measures to the device for rapid angle adjustment, and difficulty in adjusting the length of the syringe extension when the syringe is directly fixed to the device, making it inconvenient to add positioning measures to the device to position and fix the syringe extension.

[0007] The purpose and effectiveness of this adjustable-angle microinjection handheld auxiliary device are achieved through the following specific technical means:

[0008] An adjustable-angle microinjection handheld auxiliary device includes a device body; the device body is provided with a supporting plate, a fixing cylinder in the middle of the supporting plate in the left and right directions is provided, a semi-circular head block with front and rear through holes is provided on the top of the left end face of the supporting plate, two fixing holes arranged vertically and horizontally through the supporting plate are provided at the lower end of the supporting plate, an angle adjustment plate is installed on the semi-circular head block of the supporting plate through a fixing shaft, a semi-circular head with vertical through holes is provided on the left end of the angle adjustment plate, a semi-circular head block with front and rear through holes is provided in the middle of the bottom end face of the angle adjustment plate, and a semi-circular head plate with front and rear through holes is provided on both the front and rear of the right end face of the angle adjustment plate.

[0009] Furthermore, a positioning locking button is installed inside the threaded blind hole of the bearing positioning block, a threaded post is provided at the lower part of the positioning locking button, and a rotating plate with anti-slip groove is provided on the top end face of the threaded post of the positioning locking button.

[0010] Furthermore, an assembly locking plate is threadedly installed on the threaded rod of the bearing positioning block. The assembly locking plate has a threaded hole in the middle and anti-slip grooves are arranged in annular array on the outer circumference of the assembly locking plate.

[0011] Furthermore, a bearing positioning block is inserted into the top of the semi-circular head of the angle adjustment plate. A rotating column with an anti-slip groove on the outer circumference is provided on the upper part of the bearing positioning block. A threaded rod is provided on the bottom end face of the rotating column of the bearing positioning block. A U-shaped groove that runs through the left and right is opened in the middle of the top end face of the rotating column of the bearing positioning block. A threaded blind hole is opened in the middle of the top end face of the rotating column of the bearing positioning block.

[0012] Furthermore, an angle linkage rod is mounted on the semi-circular head of the angle adjustment rod via a fixed shaft. The left and right ends of the angle linkage rod are provided with semi-circular head plates with through holes at the front and back. The semi-circular head plate at the left end of the angle linkage rod is mounted on the semi-circular head block of the angle adjustment plate via a fixed shaft.

[0013] Furthermore, an angle adjusting rod is installed inside the angle adjusting cylinder via threads. The angle adjusting rod has threads on its outer circumference, and a semi-circular head with front and rear through holes is provided at the left end of the angle adjusting rod.

[0014] Furthermore, an angle adjusting cylinder is installed on the right side of the fixed cylinder that forms the bearing plate via a bearing. The angle adjusting cylinder has a threaded inner circumference, a bearing ring groove is provided on the outer circumference of the left end of the angle adjusting cylinder, and an anti-slip groove is arranged in an annular array on the outer circumference of the right side of the angle adjusting cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The convenient angle adjustment plate is mounted on the component support plate via a fixed shaft for flipping and adjustment. This allows the syringe to be flipped and adjusted synchronously via the angle adjustment plate, solving the problem that the syringe injection angle adjustment process is cumbersome, resulting in low injection efficiency and the inconvenience of adding angle adjustment measures to the device for quick angle adjustment.

[0017] It facilitates the insertion of the syringe into the carrier positioning block and locking it in place with the positioning locking button. It also facilitates the insertion of the carrier positioning block into the angle adjustment plate and locking it in place with the assembly locking plate. This solves the problem that the syringe is directly fixed to the device, which makes it difficult to adjust the length of the syringe extension and makes it inconvenient to add positioning measures to the device to position the length of the syringe extension before fixing it.

[0027] This utility model provides an adjustable-angle handheld microinjection auxiliary device, including a device body 1. The device body 1 is provided with a supporting plate 2 for supporting various components. A left-right fixed cylinder is provided in the middle of the supporting plate 2 to facilitate the installation of the angle adjustment cylinder 4 via bearings. A semi-circular head block with front and rear through holes is provided on the top of the left end face of the supporting plate 2 to facilitate the installation of the angle adjustment plate 3 via a fixed shaft. Two vertically arranged horizontally through holes are provided at the lower end of the supporting plate 2 to facilitate the fixing of the supporting plate 2 to external equipment with bolts. An angle adjustment plate 3 is installed on the semi-circular head block of the supporting plate 2 via a fixed shaft to facilitate the vertical rotation of the angle adjustment plate 3. A semi-circular head with vertical through holes is provided on the left end of the angle adjustment plate 3 to facilitate the insertion of the positioning block 7. A semi-circular head block with front and rear through holes is provided in the middle of the bottom end face of the angle adjustment plate 3 to facilitate the installation of the angle linkage rod 6 via a fixed shaft. The angle adjustment plate 3 has semi-circular head plates with through holes on both the front and back of its right end, facilitating the installation of the bearing plate 2 via a fixed shaft. An angle adjustment cylinder 4 is mounted on the right side of the fixed cylinder of the bearing plate 2 via a bearing, allowing for rotation. The angle adjustment cylinder 4 has threads on its inner circumference, facilitating the installation of the angle adjustment rod 5 via these threads. A bearing annular groove is located on the outer circumference of the left end of the angle adjustment cylinder 4, also facilitating its installation via a bearing. Anti-slip grooves are arranged in an annular array on the outer circumference of the right side of the angle adjustment cylinder 4, preventing slippage during rotation. An angle adjustment rod 5 is mounted inside the angle adjustment cylinder 4 via threads, facilitating its movement through thread engagement. The angle adjustment rod 5 also has threads on its outer circumference, facilitating its installation via these threads. The left end of the angle adjustment rod 5 has a semi-circular head with through holes on both the front and back, facilitating the installation of the angle linkage rod 6 via a fixed shaft.

[0028] Angle adjustment rod 5 has an angle linkage rod 6 mounted on its semi-circular head via a fixed shaft, facilitating its rotation. The angle linkage rod 6 has semi-circular head plates with through holes on both its left and right ends, allowing for the installation of the angle adjustment plate 3 and angle adjustment rod 5 via the fixed shaft. The semi-circular head plate on the left end of the angle linkage rod 6 is mounted on the semi-circular head block of the angle adjustment plate 3 via the fixed shaft, allowing the angle linkage rod 6 to rotate the angle adjustment plate 3. A bearing positioning block 7 is inserted into the top of the semi-circular head of the angle adjustment plate 3 to support the syringe. The bearing positioning block 7 has a rotating column with an anti-slip groove on its outer circumference, providing a secure grip. A threaded rod is provided on the bottom end face of the rotating column of the bearing positioning block 7, facilitating the assembly of the locking plate 8 via threaded installation. A U-shaped groove running through the center of the top end face of the rotating column of the bearing positioning block 7 is provided. To facilitate the insertion of the syringe, a threaded blind hole is provided in the middle of the top end face of the rotating column of the bearing positioning block 7, which facilitates the installation of the positioning locking button 9 by thread. An assembly locking plate 8 is installed on the threaded rod of the bearing positioning block 7 by thread, which facilitates the locking of the bearing positioning block 7 onto the angle adjustment plate 3. The assembly locking plate 8 has a threaded hole in the middle, which facilitates the installation of the assembly locking plate 8 by thread. The outer circumference of the assembly locking plate 8 is provided with an anti-slip groove array, which facilitates the rotation of the assembly locking plate 8 to prevent slippage. The positioning locking button 9 is installed inside the threaded blind hole of the bearing positioning block 7, which facilitates the locking and positioning of the syringe by the positioning locking button 9. The lower part of the positioning locking button 9 is provided with a threaded column, which facilitates the installation of the positioning locking button 9 by thread. The top end face of the threaded column of the positioning locking button 9 is provided with a rotating plate with anti-slip grooves, which facilitates the rotation of the positioning locking button 9 to prevent slippage.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this invention, when the device body 1 is in use, the supporting plate 2 is fixed to the external device with bolts. The syringe is placed into the U-shaped groove of the supporting positioning block 7, and the length of the left protruding part of the syringe is determined. Then, the positioning locking button 9 is screwed into the threaded blind hole of the supporting positioning block 7, and the syringe is pressed and positioned by the positioning locking button 9. Then, the supporting positioning block 7 with the syringe is inserted into the semi-circular head of the angle adjustment plate 3. The assembly locking plate 8 is installed on the threaded rod of the supporting positioning block 7 by threads. Thus, the supporting positioning block 7 is locked and fixed on the angle adjustment plate 3 by the assembly locking plate 8, as shown in the figure. Figure 1 As shown, this method solves the problem of difficulty in adjusting the length of the syringe extension caused by the syringe being directly fixed to the device. Figure 1As shown, when the angle adjusting plate 3 is adjusted, the angle adjusting cylinder 4 is rotated to engage with the angle adjusting rod 5 via a threaded connection. This causes the angle adjusting rod 5 to move to the right through the threaded engagement. The angle adjusting rod 5 then drives the right end of the angle linkage rod 6 to move to the right simultaneously. The left end of the angle linkage rod 6 causes the angle adjusting plate 3 to flip downwards. The angle adjusting plate 3 then drives the bearing positioning block 7 to flip downwards simultaneously. The bearing positioning block 7 then drives the syringe to flip downwards simultaneously, as shown in the diagram. Figure 3 As shown, this enables the adjustment of the syringe angle, solving the problem that the syringe injection angle adjustment process is cumbersome and results in low injection efficiency.

[0031] Example 2: Unlike Example 1, the outer circumferential surface of the angle adjustment cylinder 4 can also be set as a frosted surface, thereby increasing the friction between the outer circumferential surface of the angle adjustment cylinder 4 and the hand, and preventing the outer circumferential surface of the angle adjustment cylinder 4 from slipping when rotating.

[0032] Example 3: The difference from Example 1 is that the outer circumferential surface of the assembly locking plate 8 can also be set as a frosted surface, thereby increasing the friction between the outer circumferential surface of the assembly locking plate 8 and the hand, and preventing the outer circumferential surface of the assembly locking plate 8 from slipping when rotating.
