[0037] Reference Figure 3-Figure 4 , Figure 3 The overall schematic diagram of the injection mounting clamp in one embodiment of the utility model, Figure 4 The figure is an exploded schematic diagram of the injection mounting clamp in one embodiment of the utility model. One embodiment of the utility model proposes a quick-release fixing device for a syringe 4, including a syringe mounting clamp 2, the syringe mounting clamp 2 is provided with a tube clamp 21, a positioning plate clamp 22, the positioning plate clamp 22 is provided with a clamping plate 221 and a clamping seat 222, the clamping seat 222 is connected with the tube clamp 21 through a tube body mounting hole 23, the clamping plate 221 is provided with a push rod avoidance opening 2211, and clamping plates 2212 are provided on both sides of the push rod avoidance opening 2211, and a disassembly button 24 is provided at one end of the clamping seat 222, one end of the clamping plate 221 is hinged with the clamping seat 222, and the other end is provided with a clamping plate 2212 that is clamped with the disassembly button 24.

[0038] It should be noted that the quick-release fixing device is mainly used to fix and install the syringe 4. Similar to the prior art, the quick-release fixing device of the present application is provided with a tube clamp 21 for installing the tube body of the syringe 4, and is provided with a clamp 221 and a clamp seat 222. The clamp 221 cooperates with the clamp seat 222 to clamp the head positioning plate of the syringe 4 to achieve the function of disassembling and assembling the syringe 4. However, in the prior art, the clamp 221 is usually directly connected to the tube clamp 21 to achieve the purpose of clamping the syringe 4. A disassembly groove is usually provided in the tube clamp 21. When disassembling, medical staff usually need to manually disassemble through the disassembly groove. The disassembly process is time-consuming and labor-intensive, and the operation process is relatively complicated, which easily leads to a longer clinical operation process and low efficiency.

[0039] In order to improve the rotation efficiency of syringes 4 of the same specifications on the fixing device, the embodiment of the present application designs the existing fixing device, which can improve the rotation efficiency of the syringe 4 on the fixing device. The structural composition and quick-release method of the quick-release fixing device for the syringe 4 of the present application will be described below.

[0040] Please continue reading Figure 3 , Figure 4, wherein, exemplarily, the syringe mounting clamp 2 includes a tube clamp 21, a positioning plate clamp 22 and a disassembly button 24, wherein the tube clamp 21 is used to fix the tube body portion of the syringe 4, the positioning plate clamp 22, is composed of a clamp plate 221 and a clamp seat 222, the clamp plate 221 and the clamp seat 222 cooperate to fix the positioning plate or similar components of the syringe 4, and the disassembly button 24 is arranged at one end of the clamp seat 222, for controlling the opening of the clamp plate 221, so as to realize the rapid installation and disassembly of the syringe 4.

[0041] It should be noted that a push rod avoidance opening 2211 is provided on the splint 221 for avoiding the push rod of the syringe 4 to prevent the syringe 4 from being unable to be fixedly installed in the tube clamp 21. A rotating shaft mounting seat is provided at the end of the clamp seat 222 opposite to the disassembly and assembly button 24. A rotating shaft is provided on the splint 221. The splint 221 and the clamp seat 222 are hinged to the rotating shaft mounting seat through the rotating shaft to realize the relative rotation of the splint 221 and the clamp seat 222, and the other end of the splint 221 is snap-connected with the disassembly and assembly button 24, so that the disassembly and assembly button 24 can control the opening and closing state of the splint 221 as a whole.

[0042] In actual use, the installation of the syringe 4 only requires opening the clamp 221, and after the syringe 4 passes through the tube body mounting hole 23, it is fixed in the tube clamp 21, and then the clamp 221 is pressed and engaged with the disassembly button 24 to further achieve complete fixation of the syringe 4. When the syringe 4 completes the injection, when replacing the syringe 4 of the same specification, it is only necessary to press the disassembly button 24, open the clamp 221, put the syringe 4 into the tube clamp 21 again, and press and engage the clamp 221 with the disassembly button 24 to achieve replacement of the syringe 4 of the same specification. It can be understood that the size of the tube clamp 21 can be set according to the specifications of the syringe 4, and the push rod avoidance opening 2211 can avoid the head and push rod of the syringe 4 when the clamp 221 is pressed and engaged with the disassembly button 24, so as to ensure that the syringe 4 can be normally installed in the tube clamp 21.

[0043] In the above embodiment, the utility model provides a disassembly button 24 at one end of the clamp seat 222 to control the opening and closing of the clamp plate 221 , thereby realizing the rapid installation and disassembly of the syringe 4 .

[0044] See also Figure 4 and Figure 5 , Figure 5Schematic diagram of the first buckle 242 in one embodiment of the utility model. In one embodiment, the disassembly button 24 includes a button 241, a first buckle 242 and a torsion spring, the button 241 is provided with a limited clamping block 2411, one end of the first buckle 242 is provided with a torsion spring mounting portion 2421, the torsion spring mounting portion 2421 is abutted against the bottom of the limited clamping block 2411, the torsion spring is used to provide a restoring force for the button 241 and is arranged on the torsion spring mounting portion 2421 through a fixed shaft 243, the positioning plate clamp 22 is provided with a second buckle 2221, and the limited clamping block 2411 is movably clamped under the second buckle 2221.

[0045] In the above embodiment, please continue to refer to Figure 4 The disassembly and assembly button 24 is composed of a button 241, a first buckle 242, a torsion spring and a fixed shaft 243. The button 241 is the part directly operated by medical staff and is used for pressing. The limiting block 2411 is arranged on the support rod below the button 241, and is used to be movably engaged with the second buckle 2221, and abuts against the torsion spring mounting portion 2421 of the first buckle 242. The torsion spring in the torsion spring mounting portion 2421 is arranged in the torsion spring mounting portion 2421 through the fixed shaft 243. The torsion spring provides a restoring force for the disassembly and assembly button 241, ensuring that the button 241 can smoothly return to the initial position after being pressed; the second buckle 2221 is located on the positioning plate clamp 22, and interacts with the limiting block 2411 on the button 241. When the button 241 is pressed, the limit block 2411 will separate from the second buckle 2221, and at the same time, the limit block 2411 will press down the torsion spring mounting portion 2421. During the process of pressing down the button 241, the upper end of the first buckle 242 will gather toward the center. When reaching a certain limit, the card plate 2212 will separate from the first buckle 242, thereby realizing the opening and closing of the positioning plate clamp 22.

[0046] It is understandable that the disassembly button 24 realizes the function of quick installation and disassembly of the positioning plate clamp 22 through the cooperation of the button 241, the first buckle 242, the torsion spring, the limit block 2411 and the second buckle 2221. The medical staff only needs to press the button 241, the limit block 2411 and the second buckle 2221 are separated, and the positioning plate clamp 22 can be opened; when the button 241 is released, the restoring force provided by the torsion spring will make the button 241 return to its original position, and the limit block 2411 and the second buckle 2221 are re-engaged, thereby fixing the positioning plate clamp 22.

[0047] See also Figure 4 In one embodiment, the disassembly button 24 further includes a button mounting shell 244 , and the button mounting shell 244 is detachably fixedly connected to the clamp seat 222 .

[0048] In the above embodiment, the button mounting shell 244 mainly plays the role of protecting and fixing the button 241. It provides a stable structure, so that the button 241 can be stably mounted in an appropriate position, and can prevent dust, dirt or other impurities from entering the interior of the button 241 and affecting the normal operation of the button 241.

[0049] It is understood that the button mounting shell 244 generally has a cavity matching the shape of the button 241 so that the button 241 can be embedded therein. In the present application, after the button mounting shell 244 and the clamp seat 222 are fixed by bolts, a cavity matching the shape of the button 241 is formed for accommodating and installing the disassembly button 24. The detachable fixed connection between the button mounting shell 244 and the clamp seat 222 makes the disassembly button 24 more flexible and easy to maintain. When the button 241 needs to be replaced or repaired, the button mounting shell 244 can be easily disassembled without the need for complicated disassembly operations on the entire disassembly button 24.

[0050] See also Figure 1 , Figure 2 , Figure 6 , Figure 6 This is an overall schematic diagram of another injection mounting clamp in one embodiment of the utility model. In one embodiment, the quick-release fixing device for a syringe includes a fixing seat 1, the fixing seat 1 is provided with a connecting rod 11, the tube clamp 21 is provided with a connecting block 211, the end face of the connecting block 211 is provided with a connecting hole 2111, and a side surface is provided with a threaded hole 2112 that matches the connecting hole 2111, the fixing seat 1 is provided with a connecting rod 11, and the connecting rod 11 is inserted into the connecting hole 2111 and is fastened to the threaded hole 2112 by a bolt. The quick-release fixing device for a syringe also includes a marker 3, and a positioning column 2113 is also provided on one side of the connecting block 211, and the positioning column 2113 is detachably connected to the marker 3.

[0051] In the above example, see Figure 1 , Figure 2 , Figure 1 An overall schematic diagram of a quick-release fixing device in one embodiment of the utility model. Figure 2It is an exploded schematic diagram of a quick-release fixture in an embodiment of the utility model. Exemplarily, the fixing seat 1 and the marker 3 are both detachably connected to the syringe mounting clamp 2 to form a quick-release fixture for mounting and fixing the syringe 4. The fixing seat 1 is the fixed part of the device, which is used to fix the device in a certain position. For example, the fixing seat 1 can be installed on a mechanical arm to realize the automatic mechanical operation of the quick-release fixture. The syringe mounting clamp 2 is used to fix and install the syringe 4; the marker 3 is used to mark the position of the syringe 4, which is convenient for locating or identifying the position where the syringe 4 needs to be injected. At the same time, since the fixing seat 1 and the marker 3 are both detachably connected to the syringe mounting clamp 2, the fixing seat 1 and the marker 3 can be conveniently removed from the syringe mounting clamp 2, so as to realize the rapid disassembly and assembly of the quick-release fixture, and facilitate the replacement and maintenance of the quick-release fixture. Specifically, the fixing seat 1 and the marker 3 are both detachably connected to the syringe mounting clamp 2 by bolts.

[0052] In the above embodiment, the tube clamp 21 is a part of the syringe mounting clamp 2, which is used to firmly fix the tube body of the syringe 4 to ensure that the syringe 4 can be stably mounted on the quick-release fixture during use. The tube clamp 21 is provided with a connecting block 211, which is a key component for connecting the tube clamp 21 with the fixing seat 1. The design of the connecting block 211 enables the tube clamp 21 to be firmly connected to the fixing seat 1, and is also convenient for disassembly and assembly. The fixing seat 1 is the fixing part of the entire quick-release fixture, which is used to fix the device in an appropriate position, such as on an operating table or a bracket or a robotic arm.

[0053] It is understandable that a connecting hole 2111 is provided on the end face of the connecting block 211. This connecting hole 2111 is where the connecting rod 11 of the fixing seat 1 is inserted, and is used to achieve the preliminary connection between the pipe clamp 21 and the fixing seat 1. A threaded hole 2112 that matches the connecting hole 2111 is provided on one side face of the connecting block 211. This threaded hole 2112 is used to receive a bolt, and through the tightening action of the bolt, the connecting rod 11 is firmly fixed in the connecting hole 2111, thereby ensuring a stable connection between the pipe clamp 21 and the fixing seat 1. The connection method between the pipe clamp 21 and the fixing seat 1 of the present application realizes a fast, stable and convenient connection and disassembly function through the coordinated use of the connecting block 211, the connecting hole 2111, the threaded hole 2112 and the connecting rod 11, thereby improving the use efficiency and convenience of the quick-release fixing device.

[0054] It should be noted that in order to further facilitate the installation of the connecting rod 11, the part of the connecting rod 11 used to cooperate with the connecting hole 2111 can be of any shape, such as a D-shaped structure, a triangular structure, etc. It can be understood that the shape of the connecting hole 2111 is adapted to the shape of the connecting rod 11.

[0055] In the above embodiment, the main function of the positioning column 2113 is to locate and connect with the marker 3. Through the positioning column 2113, the position of the marker 3 on the connecting block 211 can be ensured to be accurate, thereby ensuring that the marker 3 can work normally. The detachable connection between the positioning column 2113 and the marker 3 allows the marker 3 to be easily installed and removed. Allow medical staff to replace or repair the marker 3 at any time as needed without large-scale disassembly of the entire device. The detachable connection can be achieved in a variety of ways, such as using structures such as screws, buckles, and slots. These structures allow the marker 3 to be firmly connected to the positioning column 2113 while being easily disassembled. It is understandable that through the detachable connection between the positioning column 2113 and the marker 3, the marker 3 can be stably fixed on the connecting block 211. The marker 3 can move with the movement of the entire syringe mounting clamp 2, thereby ensuring that it can be accurately marked when performing an injection operation.

[0056] It should be noted that the positioning column 2113 is usually a raised part and can have a specific shape or size to facilitate cooperation and connection with the corresponding part of the marker 3. The preferred main body of the positioning column 2113 of the present application is a cylinder.

[0057] Please continue reading Figure 6 In one embodiment, a positioning block 2114 is provided at the end of the positioning column 2113 , and the positioning block 2114 is provided with a slot 2115 , and the slot 2115 is engaged with the marker 3 .

[0058] In the above embodiment, the positioning column 2113 is a part of the connecting block 211, and its end is the key area where the connecting block 211 contacts the marker 3. By providing a positioning block 2114 at the end of the positioning column 2113, it can be ensured that the marker 3 can be accurately and firmly fixed on the connecting block 211. The positioning block 2114 is a protruding part provided at the end of the positioning column 2113, and its shape and size are adapted to the marker 3 so as to cooperate with the marker 3. The main function of the positioning block 2114 is to provide a stable connection point so that the marker 3 can be firmly fixed on the connecting block 211, and the installation direction of the marker 3 can be controlled.

[0059] It can be understood that the card slot 2115 is an opening or a recessed portion on the positioning card block 2114, and its shape and size match a certain part of the marker 3. The main function of the card slot 2115 is to be connected with the marker 3, and through this connection, a quick and stable connection between the marker 3 and the connecting block 211 can be achieved.

[0060] See also Figure 7 , Figure 71 is an overall schematic diagram of a marker 3 in an embodiment of the utility model. In an embodiment, the marker 3 is provided with a plurality of marking points 31 .

[0061] In the above embodiment, the multiple marking points 31 on the marker 3 are used to mark the syringe 4 or the relevant injection site. Through the multiple marking points 31, medical staff can more flexibly select the position and number of markings to meet different operation requirements.

[0062] It should be noted that these marking points 31 may be evenly or unevenly distributed on the surface or specific area of ​​the marker 3, so that the user can select the appropriate marking point 31 for marking as needed. The position of the syringe 4 is fixed, that is, the relative position relationship with the marking point 31 is determined. After the positioning system is registered, the position and posture of the syringe 4 can be tracked in real time in the positioning system. The marking principle is that since the marking points 31 are distributed in different positions, the positioning system can obtain the position information of multiple marking points 31 by scanning or tracking from multiple different angles. Based on these position information, the three-dimensional shape, size and real-time position and posture of the syringe 4 in space can be accurately calculated by using the triangulation principle, and the injection angle and depth of the syringe 4 can be accurately controlled. And the marking point 31 can be of any shape. The present application preferably uses a spherical marking point 31, which has a round and smooth appearance. This shape enables the marking point 31 to reduce friction and resistance when contacting the syringe 4 or related parts, thereby making it easier to perform the marking operation.
