Description

Technical Field

[0001] This application relates to the field of syringe clamping technology, and in particular to a syringe clamping device. Background Technology

[0002] Microsyringes typically require clamps for positioning and use. Currently, there are two types of clamping devices for microsyringes. The first type uses a screwdriver to tighten the clamp with a screw and nut. This device consists of two parts, each with a cylindrical groove in the middle for holding the microsyringe. Both parts have holes at all four ends for tightening the screw and nut to secure the microsyringe. The second type uses a snap-fit ​​mechanism to hold the microsyringe. This device also consists of two parts, each with a cylindrical groove in the middle for holding the microsyringe. One end is a rotating shaft that can be opened and closed, while the other end has a snap-fit ​​mechanism to lock or unlock the syringe.

[0003] Based on the above two types of clamps, the following problems exist: First, they are prone to crushing micro-syringes. Since micro-syringes are made of glass, they are easily crushed during the fastening and locking process if the force is not properly controlled. Second, the connection between the micro-syringe and the clamp is cumbersome. In the first device, a screwdriver is required for operation. In the second device, disassembly and assembly require pressing against the surface of the clamp and then forcefully fastening and pulling it out, which is time-consuming and laborious.

[0004] Therefore, it is necessary to design a syringe clamping device to solve the above problems. Utility Model Content

[0005] In view of this, in order to overcome the shortcomings of the prior art, this utility model provides a syringe clamping device, which effectively solves the problems of existing clamps easily crushing micro syringes due to poor force control during the fastening and locking process, as well as the cumbersome, time-consuming and labor-intensive operation of connecting the syringe and the clamp.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] According to the present invention, a syringe clamping device is provided, such as... Figures 1 to 6 As shown, this syringe clamping device is used to hold a micro-syringe, which can be mounted on, for example, a surgical robot. The syringe clamping device includes a first clamping part 1, a second clamping part 2, and a locking part 3.

[0031] In the following description, reference will be made to Figures 1 to 6 The detailed structure of the first clamping part 1, the second clamping part 2, and the locking part 3 of the syringe clamping device is described in detail. Furthermore, in the description of the embodiment, the syringe body 7 is the micro-syringe described above.

[0032] like Figure 1 and Figure 2As shown, in this embodiment, the first end of the first clamping part 1 is pivotally disposed at the first end of the second clamping part 2. The locking part 3 includes a pivot member 301 and a locking member 302 connected to each other. The pivot member 301 is pivotally disposed at the second end of the second clamping part 2. The first clamping part 1 and the second clamping part 2 can engage with each other to form a receiving position for the syringe body 7. When the syringe body 7 is disposed in the receiving position, the pivot member 301 passes through the second end of the first clamping part 1, and the locking member 302 abuts against the surface of the first clamping part 1. Both the first and second ends of the second clamping part 2 form pivot points, namely the positions of the first pivot axis 5 and the second pivot axis 6. The first clamping part 1 is connected to the first end of the second clamping part 2 via the first pivot axis 5, and the locking part 3 is connected to the second end of the second clamping part 2 via the second pivot axis 6. The first clamping part 1 and the second clamping part 2 can engage with each other to clamp the syringe body 7. The first end of the locking part 3 is pivotally disposed on the second clamping part 2, and the second end of the locking part 3 can be locked to the first clamping part 1, thereby causing the syringe clamping device to clamp the syringe body 7. Since the locking of the syringe clamping device is achieved by locking the ends of the first clamping part 1 and the second clamping part 2 with the locking part 3, the syringe body 7 will not be compressed. The glass syringe body 7 will not be subjected to strong compressive force, reducing the risk of being crushed. Because clamping and pressing the syringe body 7 only requires three steps—first, placing the syringe body 7; second, flipping the first clamping part 1 so that the first clamping part 1 and the second clamping part 2 engage; and third, flipping the locking part 3, which clamps the first clamping part 1 and the second clamping part 2 together through the threaded engagement—this syringe clamping device has a simple overall structure and is easy to operate. It can clamp and press the syringe body 7 without the need for additional tools, saving time and effort.

[0033] The syringe clamping device, through the cooperation of the first clamping part 1, the second clamping part 2, and the locking part 3, can clamp and press the syringe body 7. The syringe clamping device has a simple overall structure and is easy to operate. It does not require additional auxiliary tools and can clamp the syringe body 7 in just three steps, saving time and effort and improving work efficiency. Since the locking part 3 is located at the end of the first clamping part 1 and the second clamping part 2, and the clamping force is adjustable, the clamping force is controllable. Even if the syringe body 7 is made of glass, there is no risk of it being crushed, thus improving safety.

[0034] Preferably, such as Figure 1 and Figure 2As shown, in this embodiment, the first end of the first clamping part 1 and the second end of the first clamping part 1 are disposed opposite to each other, and the first end of the second clamping part 2 and the second end of the second clamping part 2 are disposed opposite to each other. Specifically, in this embodiment, both the first clamping part 1 and the second clamping part 2 can be formed into a block structure that is approximately rectangular, and the first and second ends of both are disposed opposite to each other, which facilitates clamping the syringe body 7 and also facilitates operation.

[0035] Furthermore, a pivot block 101 is provided at the first end of the first clamping part 1, and a connecting groove 102 is provided at the second end of the first clamping part 1. A first pivot groove 201 is provided at the first end of the second clamping part 2, and a second pivot groove 202 is provided at the second end of the second clamping part 2. The pivot block 101 is disposed in the first pivot groove 201, and the pivot member 301 is disposed in the second pivot groove 202. A first pivot shaft 5 and a second pivot shaft 6 are respectively provided in the first pivot groove 201 and the second pivot groove 202. The pivot block 101 is rotatably connected to the first pivot shaft 5, and the pivot member 301 is rotatably connected to the second pivot shaft 6.

[0036] Preferably, such as Figures 1 to 4 As shown, in this embodiment, the first clamping part 1 is provided with a first semi-circular groove 103, and the pivot block 101 is provided at both ends of the first semi-circular groove 103. The second clamping part 2 is provided with a second semi-circular groove 203, and the first pivot groove 201 is provided at one end of the second semi-circular groove 203. The first semi-circular groove 103 and the second semi-circular groove 203 can engage with each other to form a receiving position. Figure 3 As shown, it can be understood that the pivot blocks 101 are located at both ends of the first semicircular groove 103 in the length direction, that is, there are two pivot blocks 101. Figure 4 As shown, the two second semicircular grooves 203 are coaxial, which can also be understood as one second semicircular groove 203 being divided in half from the middle. Each second semicircular groove 203 has a first pivot groove 201 at one end, and one first pivot groove 201 corresponds to one pivot block 101. Similarly, in this embodiment, there are two connecting grooves 102 and two second pivot grooves 202, and they are arranged in a one-to-one correspondence. The pivot member 301 can pass through both the connecting groove 102 and the second pivot groove 202 simultaneously.

[0037] Preferably, such as Figure 2 As shown, in this embodiment, the locking member 302 is movable along the length of the pivot member 301. The locking member 302 may be, for example, a nut, and the pivot member 301 may be, for example, a hinged screw. The locking member 302 is movable on the pivot member 301 through a threaded connection.

[0038] Preferably, such as Figure 3As shown, in this embodiment, a clamping groove 104 is provided at the top of the second end of the first clamping part 1, and the locking member 302 can abut against the clamping groove 104. The clamping groove 104 is also connected to the connecting groove 102. When the first clamping part 1 and the second clamping part 2 are engaged, the pivot member 301 rotates and rotates into the interior of the connecting groove 102. Since the pivot member 301 is relatively long, the end of the pivot member 301 can extend out of the connecting groove 102. The locking member 302 is connected to the pivot member 301 that extends out of the connecting groove 102. At this time, the user can rotate the locking member 302, and the locking member 302 can move along the pivot member 301. When the locking member 302 approaches and abuts against the clamping groove 104, the first clamping part 1 and the second clamping part 2 that are engaged with each other are clamped.

[0039] Preferably, such as Figure 5 and Figure 6 As shown, in this embodiment, the syringe clamping device can switch between a disengaged state and a engaged state. In the disengaged state (e.g., ... Figure 5 As shown), the user can place or remove the syringe body 7 in the locked state (e.g., Figure 6 As shown), the syringe body 7 is compressed.

[0040] Furthermore, when the syringe clamping device is in the disassembled state, the first clamping part 1 and the second clamping part 2 are separated from each other, and the locking member 302 is away from the second end of the second clamping part 2, that is, the locking member 302 does not abut against the clamping groove 104. The locking member 302 is always located at the connecting end of the pivot member 301 (the pivot member 301 may include a pivot end connected to the second pivot shaft 6 and a connecting end connected to the locking member 302). This arrangement can prevent the locking member 302 from being lost. At the same time, in order to avoid the locking member 302 interfering with the pivoting of the first clamping part 1, in the disassembled state, the locking member 302 is away from the position where the second pivot shaft 6 is located, so that the pivot member 301 has sufficient length to prevent the locking member 302 from interfering with the connecting groove 102.

[0041] Furthermore, when the syringe clamping device is in the engaged state, the first clamping part 1 and the second clamping part 2 are engaged with each other, the syringe body 7 is positioned in the receiving position, and the locking member 302 abuts against the clamping groove 104.

[0042] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, silicone pads 4 are provided inside both the first semicircular groove 103 and the second semicircular groove 203. The silicone pads 4 can directly contact the syringe body 7. When the first clamping part 1 and the second clamping part 2 are pressed, the silicone pads 4 can buffer part of the clamping force, preventing breakage of the syringe body 7. The silicone pads 4 can also reduce the sliding of the syringe body 7 in the axial direction.

[0043] Preferably, such as Figure 4 As shown, in this embodiment, the bottom of the second clamping part 2 is provided with a connecting support part, which may include a support block 204 and a connecting block 205. The top end of the support block 204 is connected to both ends of the second semicircular groove 203, and the support block 204 is disposed on the connecting block 205. This syringe clamping device can be connected to a surgical robot (not shown) through the connecting support part. Since there are two second semicircular grooves 203, there are also two support blocks 204. The connecting block 205 can be formed into a cuboid plate structure for easy connection with the surgical robot.

[0044] Preferably, such as Figure 2 As shown, in this embodiment, the pivot member 301 may include a pivot disk 303 and a connecting rod 304. The pivot disk 303 is rotatably disposed in the second pivot groove 202, and the connecting rod 304 is disposed on the side wall of the pivot disk 303. The locking member 302 is connected to the connecting rod 304. The length of the connecting rod 304 is relatively long and longer than the sum of the lengths of the connecting groove 102 and the pressing groove 104, so that when the first clamping part 1 is pivoted, the locking member 302 can be located outside the rotation radius of the first clamping part 1, avoiding interference.

[0045] Preferably, such as Figure 2 As shown, in the embodiment, the locking member 302 may include an abutment portion 305 and a nut portion 306. The nut portion 306 is connected to the connecting rod 304 through the abutment portion 305. The abutment portion 305 can abut against the first clamping portion 1, that is, abut against the pressing groove 104. The size of the nut portion 306 is larger than the size of the abutment portion 305. When the abutment portion 305 abuts against the pressing groove 104, the nut portion 306 can prevent the first clamping portion 1 from coming out.

[0046] The assembly process of the syringe clamping device is as follows: the first clamping part 1 and the second clamping part 2 are connected by the first pivot shaft 5, and the locking part 3 and the second clamping part 2 are connected by the second pivot shaft 6. Silicone pads 4 are respectively placed in the first semi-circular groove 103 and the second semi-circular groove 203, providing protection and anti-slip effects. Then, the syringe body 7 is placed into the second semi-circular groove 203, and the first clamping part 1 is flipped so that the first semi-circular groove 103 and the second semi-circular groove 203 interlock and clamp the syringe body 7. Finally, the locking part 3 is flipped so that it is positioned in the connecting groove 102 of the first clamping part 1. Then, the locking member 302 is screwed on so that it moves towards the pressing groove 104 until it presses against the pressing groove 104, thereby clamping the syringe body 7. To remove the syringe body 7, the locking member 302 is rotated in the opposite direction, the locking part 3 is flipped, and then the first clamping part 1 is flipped.

[0047] This syringe clamping device, through the cooperation of a first clamping part, a second clamping part, and a locking part, can clamp and press the syringe body. The overall structure of the syringe clamping device is simple and easy to operate. It does not require additional auxiliary tools and can clamp the syringe body in just three steps, saving time and effort and improving work efficiency. Since the locking part is located at the end of the first clamping part and the second clamping part, the clamping force is adjustable, so the clamping force is controllable. Even if the syringe body is made of glass, there is no risk of it being crushed, thus improving safety.

[0048] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them.
