[0030] Please refer to Figure 1 and Figure 4 The embodiment provides a catheter winding fixing device 100, which comprises a support plate 110, a first passive clamping piece 120 and a second passive clamping piece 130 arranged on the support plate 110, the first passive clamping piece 120 and the second passive clamping piece 130 are arranged on opposite sides of a wound catheter 200, and the first passive clamping piece 120 and the second passive clamping piece 130 clamp the two ends of the catheter 200; a plurality of auxiliary passive clamping pieces are further arranged on the support plate 110, and the auxiliary passive clamping pieces are used for clamping the winding part of the catheter 200.

[0031] Specifically, the application provides a catheter winding fixing device 100, which comprises a support plate 110 for supporting and fixing a first passive clamp 120, a second passive clamp 130 and a plurality of auxiliary passive clamps. The two ends of a catheter 200 are oppositely arranged, and the middle part of the catheter 200 is arranged in a winding manner on the surface of the support plate 110. The first passive clamp 120 and the second passive clamp 130 are used for clamping the leading end and the trailing end of the catheter 200 respectively, so that the position of the catheter 200 is fixed, and the catheter 200 is prevented from sliding off the support plate 110. Further, in order to avoid the winding part of the catheter 200 from scattering, the auxiliary passive clamp is used for clamping the winding part of the catheter 200, so as to improve the fixing effect of the winding of the catheter 200.

[0032] The catheter 200 fixed by the first passive clamp 120, the second passive clamp 130 and the auxiliary passive clamp can be accurately placed at a specific position of the support plate 110, and can follow the rotation of the support plate without being scattered due to displacement. The catheter 200 can complete the process requirements such as repeated precision feeding and joint assembly. At the same time, the catheter winding fixing device 100 can flexibly fix the catheter 200 with different winding turns and different winding radii, thereby improving the flexibility and adaptability of the catheter 200 winding fixing.

[0033] It should be noted that, first, as shown in Figure 1 In an embodiment of the application, the center axes of the first passive clamp 120 and the second passive clamp 130 coincide; the auxiliary passive clamp comprises a first auxiliary passive clamp 140, and the first auxiliary passive clamp 140 is located at the midpoint of the line connecting the first passive clamp 120 and the second passive clamp 130.

[0034] Specifically, when the catheter 200 is in a winding state, the catheter 200 at the two ends thereof respectively extends from the opposite sides of the winding part and is clamped by the first passive clamp 120 and the second passive clamp 130 respectively. In order to further improve the clamping stability of the catheter 200 fixing device and prevent the catheter 200 from scattering due to displacement when the support plate 110 drives the catheter 200 to rotate, the center axes of the first passive clamp 120 and the second passive clamp 130 coincide, and the first auxiliary passive clamp 140 is used for clamping the midpoint of the line connecting the first passive clamp 120 and the second passive clamp 130, so that the clamping stress of the leading end and the trailing end of the catheter 200 and the middle part is uniform, and the clamping stability and accuracy are improved.

[0035] Second, as shown in Figure 4As shown in one embodiment of the present application, the first passive clamp 120 comprises a first pressing rod 121 and first and second passive clamp plates 122 and 123 which are respectively in driving connection with the first pressing rod 121. The first pressing rod 121 is sleeved with an elastic member 170 at one end close to the first and second passive clamp plates 122 and 123, and the elastic member 170 drives the first and second passive clamp plates 122 and 123 to approach each other. The first pressing rod 121 is driven to move towards the first and second passive clamp plates 122 and 123, and the first and second passive clamp plates 122 and 123 are separated from each other. The second passive clamp 130 comprises a second pressing rod 131 and third and fourth passive clamp plates 132 and 133 which are respectively in driving connection with the second pressing rod 131. The second pressing rod 131 is sleeved with an elastic member 170 at one end close to the third and fourth passive clamp plates 132 and 133, and the elastic member 170 drives the third and fourth passive clamp plates 132 and 133 to approach each other. The second pressing rod 131 is driven to move towards the third and fourth passive clamp plates 132 and 133, and the third and fourth passive clamp plates 132 and 133 are separated from each other.

[0036] Specifically, as shown in the drawings, Figure 4 The first and second passive clamps 120 and 130 are both constant-pressure clamps. The first passive clamp 120 comprises a first pressing rod 121 and oppositely arranged first and second passive clamp plates 122 and 123 which can approach each other to clamp the leading end of the catheter 200. The first pressing rod 121 is provided with an elastic member 170 at one side close to the first and second passive clamps 120 and 130. In a normal state, the elastic member 170 can always exert an outward force on the first pressing rod 121, so that the first and second passive clamp plates 122 and 123 always approach each other and clamp the leading end of the catheter 200. When it is necessary to unlock the leading end of the catheter 200, the operator can press the first pressing rod 121 towards the arrangement direction of the first and second passive clamp plates 122 and 123 to offset the elastic force of the elastic member 170 on the first pressing rod 121. At this time, the first and second passive clamps 120 and 130 can be separated from each other to cancel the clamping of the catheter 200.

[0037] Similarly, the second passive clamp 130 comprises a second pressing rod 131 and oppositely arranged third and fourth passive clamping plates 132 and 133, which can be close to each other to clamp the tail end of the catheter 200. The second pressing rod 131 is provided with an elastic member 170 on the side close to the third and fourth passive clamps, which can always exert an outward force on the second pressing rod 131 in the normal state, so as to always make the third and fourth passive clamping plates 132 and 133 close to each other and clamp the tail end of the catheter 200. When it is necessary to unlock the tail end of the catheter 200, the operator can press the second pressing rod 131 towards the arrangement direction of the third and fourth passive clamping plates 132 and 133 to offset the elastic force of the elastic member 170 on the second pressing rod 131, at which time the third and fourth passive clamps can be away from each other to cancel the clamping of the catheter 200.

[0038] Third, as shown in one of the embodiments of the present application, the catheter winding fixing device 100 further comprises a rotary air cylinder 180 arranged on the side of the support plate 110 away from the catheter 200; the driving rod of the rotary air cylinder 180 is fixedly connected with the support plate 110 to drive the support plate 110 and the catheter 200 to rotate through the driving rod. Figure 4

[0039] Specifically, in order to meet the assembly requirements of other stations and the feeding and discharging of the catheter 200, the support plate 110 can drive the catheter 200 to rotate through the first, second and auxiliary passive clamps. Optionally, the side of the support plate 110 away from the catheter 200 is provided with a rotary air cylinder 180, and the driving rod of the rotary air cylinder 180 extends outward to be fixedly connected with the plate surface of the support plate 110. The rotary air cylinder 180 can drive the support plate 110 to rotate through the driving rod, thereby driving the catheter 200 to rotate. The catheter 200 can be rotated by 180 degrees in the vertical direction by the driving of the rotary air cylinder 180, so that the two ends of the catheter 200 are exchanged in position, meeting the feeding, discharging and assembly requirements. Through the arrangement of the rotary air cylinder 180, the rotation process of the catheter 200 is more stable and reliable, and the efficiency of the assembly and feeding and discharging of the catheter 200 is improved.

[0040] The catheter winding fixing device 100 obtained by the above design can meet the multi-turn winding fixation of the catheter 200, the flexible fixation of the winding radius of the catheter 200, and the multi-point passive clamping of the catheter 200 in the winding state, ensuring that the catheter 200 is in the winding fixed state during the installation of the joint, thereby improving the production efficiency.

[0041] In one of the embodiments of the present application, as shown in Figure 2 ​As shown, the first auxiliary passive clamping member 140 comprises the elastic member 170 and the first auxiliary clamping plate 141 and the second auxiliary clamping plate 142 arranged side by side, one end of the elastic member 170 is movably connected with the first auxiliary clamping plate 141 and the other end is movably connected with the second auxiliary clamping plate 142, the elastic member 170 drives the first auxiliary clamping plate 141 and the second auxiliary clamping plate 142 to move towards each other to clamp the winding part of the catheter 200.

[0042] Specifically, as shown in Figure 2 As shown, the first auxiliary passive clamping member 140 comprises the first auxiliary clamping plate 141 and the second auxiliary clamping plate 142, the first auxiliary clamping plate 141 and the second auxiliary clamping plate 142 are arranged side by side and can move towards or away from each other. The first auxiliary passive clamping member 140 further comprises the elastic member 170, which is arranged along the side-by-side direction of the first auxiliary clamping plate 141 and the second auxiliary clamping plate 142, so that its two ends can be connected with the first auxiliary clamping plate 141 and the second auxiliary clamping plate 142 respectively. In the normal state, the first auxiliary clamping plate 141 and the second auxiliary clamping plate 142 are connected by the elastic member 170, and the elastic member 170 can exert an elastic tension on the first auxiliary clamping plate 141 and the second auxiliary clamping plate 142 to keep the first auxiliary clamping plate 141 and the second auxiliary clamping plate 142 in a state of moving towards each other for clamping the winding part of the catheter 200. Similarly, the connection of the elastic member 170 to the first auxiliary clamping plate 141 and / or the second auxiliary clamping plate 142 is released to cancel the elastic tension of the elastic member 170 on the first auxiliary clamping plate 141 and / or the second auxiliary clamping plate 142, and at this time the first auxiliary clamping plate 141 and / or the second auxiliary clamping plate 142 no longer move away from each other under the elastic tension to release the clamping of the winding part of the catheter 200 by the first auxiliary passive clamping member 140.

[0043] For example, as shown in Figure 2 The first auxiliary passive clamping member 140 further comprises a push plate 143, an engaging driving gear 144 and a driven gear 145; the end of the push plate 143 is arranged in a stack with the first auxiliary clamping plate 141 and is hinged, the side of the first auxiliary clamping plate 141 away from the push plate 143 is provided with the driving gear 144, the driving gear 144 is in transmission connection with the push plate 143; the driven gear 145 is arranged in engagement with the driving gear 144; the second auxiliary clamping plate 142 is in transmission arrangement with the driven gear 145; the push plate 143 is pushed to drive the first auxiliary clamping plate 141 to move towards the direction away from the second auxiliary clamping plate 142, at the same time, the second auxiliary clamping plate 142 is driven by the driving gear 144 and the driven gear 145 to move towards the direction away from the first auxiliary clamping plate 141 until the end of the elastic member 170 is separated from the first auxiliary clamping plate 141 and / or the second auxiliary clamping plate 142.

[0044] Specifically, in order to quickly and reliably release the clamping of the first auxiliary passive clamp 140 on the coiled part of the catheter 200, the first auxiliary passive clamp 140 further comprises a push plate 143, one end of the push plate 143 is hinged to the end of the first auxiliary clamp plate 141, and when the push plate 143 is driven to move, the first auxiliary clamp plate 141 can be driven to move away from the second auxiliary clamp plate 142.

[0045] In order to further ensure that the first auxiliary passive clamp 140 quickly and reliably releases the clamping on the coiled part of the catheter 200, the side of the first auxiliary clamp plate 141 away from the push plate 143 is provided with a driving gear 144, and the side of the second auxiliary clamp plate 142 away from the push plate 143 is provided with a driven gear 145, and the driving gear 144 is engaged with the driven gear 145.

[0046] When the push plate 143 is driven to move, the first auxiliary clamp plate 141 moves away from the second auxiliary clamp plate 142. At the same time, the first auxiliary clamp plate 141 drives the driving gear 144 to rotate, the driving gear 144 drives the driven gear 145 to rotate, and in turn drives the second auxiliary clamp plate 142 to move away from the first auxiliary clamp plate 141, so that the first auxiliary clamp plate 141 and the second auxiliary clamp plate 142 move away from each other, and in turn the elastic member 170 releases the connection of the first auxiliary clamp plate 141 and / or the second auxiliary clamp plate 142, so as to cancel the elastic tension of the elastic member 170 on the first auxiliary clamp plate 141 and / or the second auxiliary clamp plate 142. At this time, the first auxiliary clamp plate 141 and / or the second auxiliary clamp plate 142 no longer move away from each other under the elastic tension, so as to release the clamping of the first auxiliary passive clamp 140 on the coiled part of the catheter 200.

[0047] In an embodiment of the present application, as shown in Figure 3 The auxiliary passive clamp comprises a second auxiliary passive clamp 150 and a connecting rod mechanism 190, the second auxiliary passive clamp 150 comprises a third auxiliary clamp plate 151 and a fourth auxiliary clamp plate 152; the connecting rod mechanism 190 comprises a push rod 191 and a first stopper 192 at the end of the push rod 191, the first stopper 192 is provided with an elastic member 170, and the end of the elastic member 170 away from the first stopper 192 abuts against a second stopper 193; the third auxiliary clamp plate 151 is fixedly arranged on the support plate 110, and the fourth auxiliary clamp plate 152 is arranged on the side of the second stopper 193 away from the elastic member 170; the elastic member 170 drives the fourth auxiliary clamp plate 152 and the third auxiliary clamp plate 151 to move close to each other to clamp the coiled part of the catheter 200.

[0048] Specifically, as shown in Figure 3As shown, the auxiliary passive clamp further comprises a second auxiliary passive clamp 150 for clamping the coiled portion of the catheter 200 between the first auxiliary passive clamp 140 and the first passive clamp 120 to achieve precise positioning and clamping of the catheter 200. The second auxiliary passive clamp 150 comprises a third auxiliary clamping plate 151 and a fourth auxiliary clamping plate 152, which can move closer to or away from each other to clamp or release the catheter 200.

[0049] The auxiliary passive clamp further comprises a linkage mechanism 190, which comprises a push rod 191 and a first stop 192 at one end of the push rod 191. A second stop 193 is arranged on the side of the first stop 192 away from the push rod 191. The opposite ends of the elastic member 170 abut against the plate surfaces of the first stop 192 and the second stop 193, respectively. Preferably, the elastic member 170 comprises a plurality of elastic members. The third auxiliary clamping plate 151 is fixedly arranged on the support plate 110, and the fourth auxiliary clamping plate 152 is arranged on the side of the second stop 193 away from the elastic member 170. Since the first stop 192, the second stop 193, the elastic member 170, and the push rod 191 are all arranged in the vertical direction, in the normal state, the second stop 193 can press the elastic member 170 to drive the fourth auxiliary clamping plate 152 to always move towards the third auxiliary clamping plate 151, so that the fourth auxiliary clamping plate 152 and the third auxiliary clamping plate 151 move closer to each other to clamp the coiled portion of the catheter 200. Similarly, the push rod 191 is pushed upwards to drive the second stop 193 to move away from the first stop 192 through the elastic member 170. At this time, the fourth auxiliary clamping plate 152 and the third auxiliary clamping plate 151 move away from each other, and the second auxiliary passive clamp 150 can release the clamping of the catheter 200.

[0050] Further, as shown in the drawings, in order to adjust the clamping height of the second auxiliary passive clamp 150, the side of the second stop 193 away from the elastic member 170 is provided with a support rod 194, and the fourth auxiliary clamping plate 152 is arranged on the support rod 194. Figure 3

[0051] Optionally, the catheter coiling and fixing device 100 further comprises a housing (not shown in the drawings) arranged on the support plate 110, and the linkage mechanism 190 is movably arranged in the housing, and the fourth auxiliary clamping plate 152 extends to the outside of the housing.
