Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, specifically relating to a universal piezoelectric membrane breaking instrument piezoelectric element fixture. Background Technology

[0002] Piezoelectric perforation device (Piezo-) is based on the high-frequency vibration generated by piezoelectric ceramic materials when energized, which drives the movement of the connected micromanipulation needle. It is used in various micromanipulation needles in cloning animals and reproductive medicine to break through the zona pellucida or plasma membrane. It can greatly help operators improve the success rate of various membrane perforation and at the same time improve the survival rate of various embryos during the operation. Therefore, it is increasingly used in various biomedical basic research or clinical practice.

[0003] Currently, piezoelectric cell disruption instruments need to be used in conjunction with various types of micromanipulation systems. Typically, the piezoelectric drive unit / element, with the manipulator needle already installed, is fixed to the corresponding micromanipulation instrument. The micromanipulation instrument then drives the piezoelectric drive element and the connected micromanipulator needle closer to the target cell, finally performing various delicate operations. However, in actual installation and use, due to the diverse types of micromanipulation systems, the installation process of the corresponding piezoelectric drive element is very complex. Sometimes, to achieve the installation goal, it is even necessary to specifically remove the originally fixed needle holder from the piezoelectric element of the piezoelectric cell disruption instrument for easy installation. Furthermore, there are many cases where installation and use are impossible due to incompatibility with the corresponding micromanipulation system model. This reality seriously hinders the application and promotion of piezoelectric technology and also interferes with relevant scientific research, medical, and other practical applications. Therefore, finding a convenient and quick solution to this problem has become an urgent priority. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a universal piezoelectric element holder for a piezoelectric membrane rupture instrument, which has the advantages of easy installation and disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a universal piezoelectric membrane rupture instrument piezoelectric element holder, comprising a piezoelectric needle holder rod, one end of which is provided with a connector, and a piezoelectric operating needle is provided outside the connector; the other end of which is provided with a sleeve, and a pressure tube is provided outside the sleeve; a threaded needle holder rod is provided at the top of the piezoelectric needle holder rod; and a fixing component is provided between the threaded needle holder rod and the piezoelectric needle holder rod.

[0006] Preferably, the fixing component includes two connecting blocks, both ends of which are fixedly connected to fixing blocks. Each of the four fixing blocks has a through groove inside. The piezoelectric needle holder is located in two of the through grooves, and the threaded needle holder is located in the other two through grooves.

[0007] Preferably, the fixing block is internally threaded with a fixing bolt, and the bottom of the fixing bolt is rotatably connected to a moving block.

[0008] Preferably, a first protective pad is fixedly connected inside the through groove, and a second protective pad is fixedly connected to the bottom of the movable block. The first and second protective pads are made of rubber.

[0009] Preferably, a handle is fixedly connected to the top of the fixing bolt, and the outside of the handle is provided with anti-slip texture.

[0010] Preferably, a piezoelectric element is provided on the outside of the piezoelectric needle holder, and a power data line is provided on the outside of the piezoelectric element.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By engaging the inner slots of the four fixing blocks with the threaded needle holders of the microscopic operating system and the piezoelectric needle holders of the piezoelectric element, respectively, and then tightening the four fixing bolts, which are threadedly connected to the fixing blocks, the fixing bolts move downwards, thereby moving the connecting moving block downwards. This clamps and fixes the threaded needle holders of the microscopic operating system and the piezoelectric needle holders of the piezoelectric element. The first and second protective pads ensure that the external parts are not damaged during clamping and increase the clamping friction, making it more stable. Double-secured positioning is achieved with one fixing bolt at the front and one at the back. To ensure that the piezoelectric needle holder will not fall off the threaded needle holder of the microcontroller system due to loosening during use, thus preventing damage to the piezoelectric element and the connected piezoelectric operating needle, this design ensures a tight and reasonable connection between the threaded needle holder of the microcontroller system and the piezoelectric needle holder on the piezoelectric element. This not only solves the problem of convenient and quick installation and disassembly, but also eliminates the need for operators to make extensive adjustments to adapt to the position of the microcontroller system with the piezoelectric needle holder installed, nor to readjust the original feel of the microcontroller system with the piezoelectric element installed. This greatly simplifies the actual installation, use, and operation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a universal piezoelectric membrane rupture instrument piezoelectric element holder, including a piezoelectric needle holder 1, a connector 2 at one end of the piezoelectric needle holder 1, a piezoelectric operating needle 3 outside the connector 2, a sleeve 6 at the other end of the piezoelectric needle holder 1, a pressure tube 7 outside the sleeve 6, a threaded needle holder 8 at the top of the piezoelectric needle holder 1, a fixing component 9 between the threaded needle holder 8 and the piezoelectric needle holder 1, a piezoelectric element 4 outside the piezoelectric needle holder 1, and a power data cable 5 outside the piezoelectric element 4.

[0020] In this implementation scheme, the close and reasonable connection between the micro-operating system and the piezoelectric element 4 not only solves the problem of convenient and quick installation and disassembly, but also, in actual use, operators do not need to make extensive adjustments to adapt to the position of the micro-operating system with the piezoelectric element 4 installed, nor do they need to readjust to adapt to the original feel of the micro-operating system with the piezoelectric element 4 installed, which greatly facilitates the actual installation, use and operation.

[0021] Specifically, the fixing component 9 includes two connecting blocks 901, and fixing blocks 902 are fixedly connected to both ends of the two connecting blocks 901. Each of the four fixing blocks 902 has a through groove 908. The piezoelectric needle holder 1 is located in two of the through grooves 908, and the threaded needle holder 8 is located in the other two through grooves 908. The fixing bolt 906 is threadedly connected to the inside of the fixing block 902. The bottom of the fixing bolt 906 is rotatably connected to the moving block 904. The first protective pad 903 is fixedly connected to the inside of the through groove 908. The bottom of the moving block 904 is fixedly connected to the second protective pad 905. The first protective pad 903 and the second protective pad 905 are made of rubber. The top of the fixing bolt 906 is fixedly connected to the handle 907. The outside of the handle 907 is provided with anti-slip texture.

[0022] In this embodiment, when convenient installation is required, firstly, the inner through grooves 908 of the four fixing blocks 902 are respectively engaged with the threaded needle holder 8 of the microscopic operating system and the piezoelectric needle holder 1 on the piezoelectric element 4. Then, the four fixing bolts 906 are tightened. Since the fixing bolts 906 and the fixing blocks 902 are threadedly connected, the fixing bolts 906 are moved downwards, which in turn moves the connecting moving block 904 downwards. At this time, the threaded needle holder 8 of the microscopic operating system and the piezoelectric needle holder 1 on the piezoelectric element 4 are clamped and fixed. The first protective pad 903 and the second protective pad 905 ensure that the outside is not damaged during clamping and increase the clamping friction, making it more stable. With double-safety positioning via two 906 fixing bolts at the front and rear, it is ensured that the piezoelectric needle holder 1 will not fall off the threaded needle holder 8 of the microcontroller system due to loosening during use, thus preventing damage to the piezoelectric element 4 and the connected piezoelectric operating needle 3. Through this design, the threaded needle holder 8 of the microcontroller system and the piezoelectric needle holder 1 on the piezoelectric element 4 are tightly and reasonably connected. This not only solves the problem of convenient and quick installation and disassembly, but also eliminates the need for operators to make extensive adjustments to adapt to the position of the microcontroller system with the piezoelectric needle holder 1 installed, nor to readjust the original feel of the microcontroller system with the piezoelectric element 4 installed, greatly facilitating actual installation, use, and operation.

[0023] The working principle and usage process of this utility model are as follows: For convenient installation, firstly, the inner through grooves 908 of the four fixing blocks 902 are respectively engaged with the threaded needle holder 8 of the microscopic operating system and the piezoelectric needle holder 1 on the piezoelectric element 4. Then, the four fixing bolts 906 are tightened. Since the fixing bolts 906 and the fixing blocks 902 are threadedly connected, the fixing bolts 906 are moved downwards, which in turn moves the connecting moving block 904 downwards. At this point, the threaded needle holder 8 of the microscopic operating system and the piezoelectric needle holder 1 on the piezoelectric element 4 are clamped and fixed. The first protective pad 903 and the second protective pad 905 ensure that the external structure is not damaged during clamping and increase the clamping friction. The design ensures greater stability through double-safety positioning with two 906 fixing bolts at the front and rear. This prevents the piezoelectric needle holder 1 from falling off the threaded needle holder 8 of the microcontroller system due to loosening during use, thus protecting the piezoelectric element 4 and the connected piezoelectric operating needle 3. This design tightly and rationally connects the threaded needle holder 8 of the microcontroller system to the piezoelectric needle holder 1 on the piezoelectric element 4. This not only solves the problem of convenient and quick installation and disassembly but also eliminates the need for operators to make extensive adjustments to the position of the microcontroller system with the piezoelectric needle holder 1 installed, nor to readjust the original feel of the microcontroller system with the piezoelectric element 4 installed. This greatly simplifies the actual installation, use, and operation.
