Description

Technical Field

[0001] The present application relates to the technical field of medical device assembly, and in particular to a clamping device and a clamping method capable of realizing rapid clamping. Background Art

[0002] At present, ligation clips (also called vascular clamps or closure clamps) commonly used in clinical surgery to close tubular tissues are widely used in general surgery, hepatobiliary and pancreatic surgery, urology, thoracic surgery, gynecology and other departments.

[0003] Traditional ligation clips are mainly made of titanium metal clips and polymer material clips. However, both types of ligation clips are non-absorbable and will remain in the human body for a long time after surgery, causing a burden to patients. Therefore, a degradable magnesium metal ligation clip has been developed based on magnesium alloy, referred to as magnesium clip. Its structure includes an integrated upper arm, lower arm and O-shaped structure, and the upper arm and lower arm form a V-shape.

[0004] Magnesium clips are very popular in the market, so the assembly between them and the matching base has become the main factor affecting production capacity. The existing operation method is to put the magnesium clips into the corresponding clamping grooves of the base, and then use tweezers to manually open and fix the magnesium clips in the base one by one. However, this assembly method has low production efficiency and obvious shortcomings. Summary of the invention

[0005] In order to improve assembly efficiency, the present application provides a clamping device and a clamping method that can achieve rapid clamping.

[0006] In a first aspect, the present application provides a clamping device capable of achieving rapid clamping, which adopts the following technical solution: A clamping device capable of achieving rapid clamping comprises a workbench, on which is arranged an opening portion for placing and opening a plurality of magnesium clips, and a pressurizing portion for applying force to an O-shaped structure of the plurality of magnesium clips placed on the opening portion to open them; the opening portion comprises a bottom plate arranged on the workbench and for placing a base, and a plurality of clamping platforms arranged on the bottom plate and arranged in a row, wherein two sliding steps cooperating in an eight-shaped shape are arranged on the clamping platform, and the upper arm and the lower arm of the magnesium clip respectively abut against one sliding step; the interior of the base is hollow and the top and the bottom are both open, and when the base is placed on the bottom plate, the plurality of clamping platforms are all located inside the base.

[0007] By adopting the above technical solution, the worker manually places the base on multiple clamping platforms on the workbench, and then places the magnesium clip on each clamping platform through the opening on the top of the base, and the upper and lower arms of the magnesium clip both contact the corresponding sliding steps. The pressure part applies force to the O-shaped structure of the magnesium clip, and the upper and lower arms of the magnesium clip gradually open under the action of the two sliding steps until the magnesium clip is assembled on the base. The pressure part can achieve synchronous assembly between multiple magnesium clips and the base by applying force once, which improves assembly efficiency and increases product production capacity.

[0008] Optionally, a limiting top is arranged at a position between two sliding steps on the top of each support and clamping platform, and the limiting top is used to provide support for the O-shaped structure of the magnesium clamp; when the O-shaped structure of the magnesium clamp supports the limiting top, the magnesium clamp is assembled with the base.

[0009] By adopting the above technical solution, the O-shaped structure of the magnesium clip cooperates with the limiting top to limit the maximum downward pressure of the pressurizing part, thereby reducing the possibility of the magnesium clip being damaged due to excessive deformation or causing assembly failure due to insufficient deformation.

[0010] Optionally, a distance is left between any two adjacent clamping platforms, and positioning plates are arranged on the bottom plate next to two sliding steps on each clamping platform, and the positioning plates are used to fit tightly against the magnesium clamp.

[0011] By adopting the above technical solution, multiple positioning plates cooperate to achieve accurate positioning of the position of the magnesium clamp on each support clamping table.

[0012] Optionally, two limit bars are arranged on the bottom plate, both of which are parallel to the arrangement direction of the multiple clamping platforms, and the multiple clamping platforms are located between the two limit bars. When the base is accurately mounted on the multiple clamping platforms, the base is located between the two limit bars and is tightly attached to them.

[0013] By adopting the above technical solution, the two limit strips cooperate to achieve rapid and accurate positioning of the placement position of the base on the bottom plate.

[0014] Optionally, the pressurizing part includes a driving shaft rotatably mounted on a workbench, a fixed shaft is arranged on the driving shaft through a clamping claw, and a plurality of press-in plates for resisting the O-shaped structure of the magnesium clip are axially spaced and arranged on the fixed shaft, and one press-in plate corresponds to one magnesium clip.

[0015] By adopting the above technical solution, workers manually rotate the drive shaft, and the drive shaft drives the fixed shaft to rotate through the claws. The fixed shaft drives multiple pressed plates to synchronously extrude their corresponding magnesium clips, which greatly improves the assembly efficiency between the magnesium clips and the base.

[0016] Optionally, the portion of the pressed-in plate that is used to abut against the magnesium clip O-shaped structure is arranged in an arc shape.

[0017] By adopting the above technical solution, the arc-shaped setting is conducive to improving the stability of the magnesium clip O-shaped structure when it conflicts with the pressed-in plate, thereby improving the assembly efficiency.

[0018] Optionally, an assembly warning mark is provided on the top of the base, and the assembly warning mark is used to remind workers of the placement direction of the magnesium clip.

[0019] By adopting the above technical solution, the possibility of assembly failure or damage caused by incorrect placement direction of the magnesium clip is reduced.

[0020] In a second aspect, the present application provides a clamping method capable of realizing rapid clamping of a clamping device, which adopts the following technical solution: A clamping method capable of realizing quick clamping of a clamping device comprises the following steps: S1. The worker manually sets the unloaded base on multiple clamping platforms of the workbench, and then places at least one magnesium clamp on each clamping platform through the opening on the top of the base, with the upper arm and the lower arm of the magnesium clamp both contacting the corresponding sliding step; S2. Apply force to the O-shaped structure of the magnesium clamp through the pressure part, and the upper and lower arms of the magnesium clamp are gradually stretched open under the action of two sliding steps until the magnesium clamp is assembled on the base, and then the base is removed from the workbench.

[0021] By adopting the above technical solution, the pressurizing part can achieve synchronous assembly between multiple magnesium clips and the base by applying force once, thereby improving assembly efficiency and increasing product production capacity.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The worker manually places the base on multiple clamping tables on the workbench, and then places a magnesium clip on each clamping table through the opening on the top of the base. The upper and lower arms of the magnesium clip both contact the corresponding sliding steps. The pressure part applies force to the O-shaped structure of the magnesium clip, and the upper and lower arms of the magnesium clip gradually open under the action of the two sliding steps until the magnesium clip is assembled on the base. The pressure part can achieve synchronous assembly between multiple magnesium clips and the base by applying force at one time, which improves assembly efficiency and increases product production capacity; 2. The O-shaped structure of the magnesium clip cooperates with the limiting top to limit the maximum downward pressure of the pressurized part, reducing the possibility of damage due to excessive deformation of the magnesium clip or assembly failure due to insufficient deformation; 3. The structures of the various components in this application are relatively simplified, easy to assemble and process, which is conducive to widespread popularization and use, saves production costs, and is easy to operate, making it easy for operators to quickly get started and use it proficiently.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-2 This application is described in further detail.

[0027] The embodiment of the present application discloses a clamping device capable of achieving rapid clamping.

[0028] Example 1 Reference Figure 1 and Figure 2 The clamping device capable of realizing rapid clamping includes a horizontally placed workbench 2, on which is arranged an opening portion for placing and opening a plurality of magnesium clips 1, and a pressurizing portion for applying force to an O-shaped structure 103 of the plurality of magnesium clips 1 placed on the opening portion to open them.

[0029] Reference Figure 1 and Figure 2 The support portion includes a base plate 3 and a plurality of support clamping platforms 4 on the base plate 3. The base plate 3 is placed on the workbench 2 and welded thereto by means of pin-hole plug-in cooperation. The plurality of support clamping platforms 4 are arranged in a row on the base plate 3, and a spacing is left between any two adjacent support clamping platforms 4.

[0030] Each support and clamping platform 4 is provided with two sliding steps 41, and the two sliding steps 41 cooperate to form an eight-shaped shape, and the upper arm 101 and the lower arm 102 of the magnesium clamp 1 respectively abut against one sliding step 41. A limiting top 6 is integrally formed at the top of each support and clamping platform 4 at a position between the two sliding steps 41, and the limiting top 6 is used to support the O-shaped structure 103 of the magnesium clamp 1.

[0031] Reference Figure 1 and Figure 2 A positioning piece 7 is integrally formed on the bottom plate 3 next to the two sliding steps 41 on each clamping platform 4 , and one sliding step 41 corresponds to two positioning pieces 7 , and the positioning pieces 7 are used to be closely attached to the magnesium clamp 1 .

[0032] When a worker manually places the magnesium clip 1 on the clamping platform 4 , the corresponding positioning pieces 7 cooperate with each other to achieve accurate positioning of the magnesium clip 1 on the clamping platform 4 by closely adhering to the magnesium clip 1 .

[0033] Reference Figure 1 and Figure 2 The base 5 is hollow inside and has open top and bottom. When the base 5 is placed on the bottom plate 3, the plurality of clamping platforms 4 are located inside the base 5. A separator 15 is integrally formed between two adjacent clamping platforms 4 in the base 5, and the separator 15 is tightly attached to the corresponding two clamping platforms 4.

[0034] Reference Figure 1 and Figure 2 Two limiting bars 8 are integrally formed on the bottom plate 3 and are parallel to the arrangement direction of the plurality of clamping platforms 4. The plurality of clamping platforms 4 are located between the two limiting bars 8. The two limiting bars 8 cooperate with the plurality of partitions 15 inside the base 5 to position the placement of the base 5.

[0035] When the base 5 is accurately mounted on the plurality of support and clamping platforms 4 , the base 5 is located between the two limit bars 8 and is in close contact with them, and the partition sheet 15 is in close contact with the corresponding two support and clamping platforms 4 .

[0036] Reference Figure 1 and Figure 2 The pressure-applying part includes a driving shaft 9 rotatably mounted on the workbench 2 through a bearing, a handle 14 bolted to one end of the driving shaft 9, two claws 11 welded to the driving shaft 9, and a fixed shaft 10 welded between the two claws 11.

[0037] A plurality of press-in plates 12 are arranged axially at intervals on the fixed shaft 10 , and the press-in plates 12 are used to resist the O-shaped structure 103 of the magnesium clip 1 and correspond to it one by one, and the part of the press-in plates 12 used to resist the O-shaped structure 103 of the magnesium clip 1 is arranged in an arc shape.

[0038] Reference Figure 1 and Figure 2 The worker rotates the handle 14 , and the handle 14 drives the driving shaft 9 to rotate. The driving shaft 9 drives the multiple pressed plates 12 on the fixed shaft 10 to rotate synchronously to the O-shaped structure 103 that contacts the magnesium clip 1 through the claws 11 .

[0039] During the pressing process, the upper arm 101 and the lower arm 102 of the magnesium clip 1 are stretched apart by the two sliding steps 41 , and when the O-shaped structure 103 contacts the limiting top 6 , the magnesium clip 1 is assembled with the base 5 .

[0040] The O-shaped structure 103 of the magnesium clip 1 cooperates with the limiting top 6 to limit the maximum downward pressure of the pressurizing part, which not only reduces the possibility of damage to the magnesium clip 1 due to excessive deformation, but also ensures that the magnesium clip 1 can be opened to a sufficient angle to be fixed in the base 5.

[0041] Reference Figure 1 and Figure 2In addition, the pressurizing part can achieve synchronous assembly between multiple magnesium clips 1 and the base 5 by applying force once, which not only makes the clamping angles and positions of multiple magnesium clips 1 consistent, but also greatly improves the assembly efficiency and increases the product production capacity.

[0042] In addition, in actual use, the production capacity of the product can be adjusted accordingly by increasing or decreasing the number of the clamping tables 4 and the pressed plates 12 .

[0043] Reference Figure 2 An assembly warning mark 13 is dug on the top of the base 5, and the assembly warning mark 13 is used to remind workers of the placement direction of the magnesium clip 1, thereby reducing the possibility of assembly failure or damage caused by incorrect placement direction of the magnesium clip 1.

[0044] The implementation of Example 1 is as follows: the worker manually sets the unloaded base 5 on the multiple clamping platforms 4 of the workbench 2, and then places a magnesium clamp 1 on each clamping platform 4 through the opening on the top of the base 5, and the upper arm 101 and the lower arm 102 of the magnesium clamp 1 both contact the corresponding sliding step 41. The worker rotates the handle 14, and the handle 14 drives the drive shaft 9 to rotate. The drive shaft 9 drives the multiple pressing plates 12 on the fixed shaft 10 to rotate synchronously to contact the O-shaped structure 103 of the magnesium clamp 1 through the claw 11. During the pressing process, the upper arm 101 and the lower arm 102 of the magnesium clamp 1 are stretched open by the action of the two sliding steps 41. When the O-shaped structure 103 contacts the limit top 6, the magnesium clamp 1 is just assembled with the base 5, and then the base 5 is removed.

[0045] Example 2 Embodiment 2 of the present application discloses a clamping method of a clamping device capable of realizing rapid clamping, comprising the following steps: S1. The worker manually sets the unloaded base 5 on the multiple clamping platforms 4 of the workbench 2, and then places a magnesium clamp 1 on each clamping platform 4 through the opening on the top of the base 5, and the upper arm 101 and the lower arm 102 of the magnesium clamp 1 both contact the corresponding sliding step 41; S2, the worker rotates the handle 14, the handle 14 drives the drive shaft 9 to rotate, and the drive shaft 9 drives the multiple pressing plates 12 on the fixed shaft 10 to rotate synchronously through the claws 11 to contact the O-shaped structure 103 of the magnesium clamp 1. During the pressing process, the upper arm 101 and the lower arm 102 of the magnesium clamp 1 are stretched open by the two sliding steps 41, and when the O-shaped structure 103 contacts the limit top 6, the magnesium clamp 1 is just assembled with the base 5, and then the base 5 can be removed.
