[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] As Figure 1 、 Figure 2 and Figure 3 shown, the catheter head end melt head detection device provided by the present utility model includes: a clamping assembly and an acquisition device 3.

[0035] The clamping assembly includes a clamping seat 1 and a support seat 21. The clamping seat 1 includes a chuck shaft 11 and a rotating shaft 12 that are coaxially rotatably arranged. There is a channel 112 extending along the rotation axes of the two between the chuck shaft 11 and the rotating shaft 12. The channel 112 can be penetrated by a catheter. The rotating shaft 12 can drive the chuck shaft 11 to rotate, and their rotation axes are the same. The channel 112 can also rotate along the rotation axes of the rotating shaft 12 and the chuck shaft 11, so as to facilitate observing the concentricity of the head end of the catheter clamped through the channel 112. The support seat 21 has a certain length dimension and extends along the central axis direction of the chuck shaft 11 for supporting the catheter.

[0036] A through hole 107 communicating with the channel 112 is provided on the side wall of the chuck shaft 11. The extending direction of the through hole 107 can be perpendicular to and intersect with the extending direction of the channel 112. A movable member 111 is movably arranged in the through hole 107. The end of the movable member 111 is adapted to selectively extend into the channel 112 or retract into the through hole 107. When installing or disassembling the catheter, the head end of the movable member 111 can be retracted into the through hole 107. In this state, the catheter can move freely in the channel 112. When the catheter is installed in place, the end of the movable member 111 can be extended into the channel 112 and can contact and clamp the catheter, so as to ensure that the catheter rotates synchronously with the chuck shaft 11 and will not cause damage to the catheter.

[0037] The acquisition device 3 is installed on the column 41 through an adjustable support. The clamping seat 1 is located between the acquisition device 3 and the support seat 21. The head end of the catheter extends out from one end of the channel 112 facing the acquisition device 3, and the other parts of the catheter are supported by the support seat. The acquisition device 3 can adjust the height and the angle of the lens through the adjustable support to facilitate observing and acquiring the head end of the catheter.

[0038] The clamping assembly and the acquisition device 3 can be installed on the work platform 5. Among them, the clamping seat 1 is arranged between the acquisition device 3 and the support seat 21. The head end of the catheter can pass through the channel 112 and extend out, facilitating the acquisition device 3 to observe and acquire. The other parts of the catheter can be supported by the support seat 21, and the support seat 21 can also limit the catheter to ensure that the whole catheter is coaxial with the chuck shaft 11. When installing the catheter on the chuck shaft 11, the end of the movable member 111 can be retracted into the through hole 107, so as to facilitate the catheter to smoothly extend into the channel 112. After the catheter extends in place, the end of the movable member 111 is then extended into the channel 112, and the end of the movable member 111 contacts and clamps the catheter in the channel 112. During the detection process, the rotating shaft 12 can drive the chuck shaft 11 to rotate. Due to the clamping effect of the movable member 111, the catheter can rotate synchronously with the chuck shaft 11, enabling the acquisition device 3 to comprehensively observe and acquire the key indicators of the head end of the catheter. The key indicators can include the shape, coaxiality, etc. of the head end of the catheter, which is convenient for subsequent analysis and evaluation.

[0039] The catheter head end melting head detection device provided by the utility model has a simple structure, can quickly disassemble and assemble the catheter, comprehensively observe and collect the catheter, improve the detection efficiency of the catheter, and at the same time can reduce the equipment cost.

[0040] As Figure 3 shown, in this embodiment, one end of the channel 112 facing the support base 21 is a flared opening 106, and the flared opening 106 can facilitate the catheter to extend into the channel 112.

[0041] As Figure 1 and Figure 3 shown, in this embodiment, the clamping seat 1 includes a first support column 13. The first support column 13 has a shaft hole 134. The chuck shaft 11 is rotatably installed in the shaft hole 134. A V-shaped groove is provided at the top of the support base 21. The extending direction of the V-shaped groove coincides with the extending direction of the axis of the shaft hole 134. The V-shaped groove is strip-shaped, and its cross-sectional shape is V-shaped. The V-shaped groove can support and keep the other part of the catheter extending along the axis direction of the channel 112 to limit the catheter, and ensure that the other part of the catheter can also rotate along the rotation axis of the chuck shaft 11.

[0042] The clamping assembly includes a second support column 22. The support base 21 is arranged on the second support column 22. The extending direction of the V-shaped groove coincides with the extending direction of the axis of the shaft hole 134. The first support column 13 and the second support column 22 can support the chuck shaft 11 and the V-shaped groove at a certain height from the working platform 5, and make the extending direction of the axis of the shaft hole 134 coincide with the extending direction of the V-shaped groove, and ensure that the whole catheter is in a straight state.

[0043] As Figure 3 shown, in this embodiment, a first bearing 135 and a second bearing 136 are arranged in the shaft hole 134. The chuck shaft 11 is rotatably arranged on the first bearing 135 and the second bearing 136 to ensure the stability of the rotation of the chuck shaft 11.

[0044] As [[ID=2J]] Figure 2 and Figure 3 shown, in this embodiment, the first support column 13 includes a first support block 131 and a second support block 132. The first support block 131 is detachably installed on the second support block 132. The second support block 132 can be fixedly connected to the working platform 5. The first support block 131 can be installed on the second support block 132 by screws, so as to facilitate the replacement of the shaft hole 134 with different specifications and the chuck shaft 11 with different specifications.

[0045] As Figure 3 and Figure 4As shown, in this embodiment, a limiting stop wall 119 is provided on the chuck shaft 11. During installation, the chuck shaft 11 can pass through the shaft hole 134, and the limiting stop wall 119 abuts against and limits one of the bearings. A limiting snap ring 133 is detachably provided at the opposite end of the limiting stop wall 119, and the limiting snap ring 133 abuts against and limits the other bearing, so that the chuck shaft 11 can only rotate around the axis and cannot displace in the axial direction of the axis. Furthermore, it is possible to prevent the head end of the catheter installed in the channel 112 from displacing in the axial direction, facilitating the observation and collection by the collection device 3.

[0046] As Figure 3 and Figure 4 shown, the channel 112 can be provided on the chuck shaft 11, and the rotating shaft 12 is sleeved on the chuck shaft 11, thereby reducing the manufacturing difficulty.

[0047] As Figure 4 and Figure 5 shown, in this embodiment, a locking screw 113 is provided on the through hole 107. The locking screw 113 has a guiding hole 101 communicating with the through hole 107. An elastic member 114 is provided between the end of the movable member 111 located in the through hole 107 and the locking screw 113. The movable member 111 is a cylindrical rod. The movable member 111 can move in the guiding hole 101 and the through hole 107. The elastic member 114 can push the movable member 111 to extend its end into the channel by elastic force. When installing or disassembling the catheter, the movable member 111 can be pulled in a direction away from the locking screw 113, and the elastic member 114 is compressed. After the catheter is installed in place, the external force applied to the movable member 111 can be withdrawn. The elastic member 114 resumes its original state and pushes the end of the movable member 111 to move into contact with the catheter through elastic force, and clamps the catheter in the channel 112.

[0048] As Figure 4 and Figure 5 shown, in this embodiment, the end of the movable member 111 located in the through hole 107 has a boss 115. The elastic member 114 is pre-pressed between the boss 115 and the locking screw 113. The boss 115 can support one end of the elastic member 114, facilitating the smooth movement of the elastic member 114 to push the movable member 111. For example Figure 4 shown, the elastic member 114 and the locking screw 113 can be sleeved on the movable member 111 in sequence, and then the movable member 111, the elastic member 114 and the locking screw 113 are installed in the through hole 107.

[0049] As Figure 5 and Figure 6As shown, in this embodiment, the inner wall of the guiding hole 101 has a limiting slot, and the outer wall of the movable member 111 has a limiting rib that slidably cooperates with the limiting slot. The extending directions of the limiting slot and the limiting rib are the same as the extending direction of the guiding hole 101. For example, the inner wall of the guiding hole 101 has a first slot 102 and a second slot 103 that are oppositely formed, and the outer wall of the movable member 111 has a first rib 104 and a second rib 105. The first rib 104 slidably cooperates with the first slot 102, and the second rib 105 slidably cooperates with the second slot 103, thereby restricting the movable member 111 from rotating and only allowing it to move axially along the guiding hole 101. This is because the end of the movable member 111 located inside the through hole 107 needs to contact the catheter, and there is friction between the two. If the movable member 111 rotates, the position or angle of the head end of the catheter is very likely to change, causing inconvenience for subsequent observation. At the same time, it can also prevent the outer wall of the catheter from being worn due to friction between the two.

[0050] As Figure 3 and Figure 4 shown, in this embodiment, a bracelet 117 is provided at the end of the movable member 111 located outside the through hole 107. The bracelet 117 can be detachably installed on the movable member 111 by means of the cooperation of a screw and a threaded hole. The bracelet 117 can not only facilitate the application of an external force to the movable member 111, but also abut against the locking screw 113 to limit the length of the movable member 111 extending into the through hole 107, avoiding deformation of the catheter caused by the movable member 111 extending too long into the channel 112.

[0051] As Figure 4 shown, in this embodiment, a silica gel pad 116 is provided on the surface of the end of the movable member 111 located inside the through hole 107. The silica gel pad 116 can further protect the catheter.

[0052] As Figure 3 and Figure 5 shown, in this embodiment, the head end of the chuck shaft 11 facing the collecting device 3 is a conical surface 118. The conical surface 118 can facilitate better observation of the position of the head end of the catheter, and at the same time can prevent the staff from being scratched by the chuck shaft 11 during manual operation.

[0053] As Figure 1 shown, in this embodiment, the collecting device 3 includes an electron microscope 31 and an industrial camera 32, and the adjustable support includes: a lifting mechanism 42 and a rotating seat 43.

[0054] The lifting mechanism 42 is arranged on the column 41. The rotating seat 43 is rotatably arranged on the lifting mechanism 42. The electron microscope 31 is arranged on the rotating seat 43. The lifting mechanism 42 can drive the rotating seat 43 to move along the column 41 in the height direction, so as to adjust the height of the electron microscope 31. The rotating seat 43 can rotate relative to the lifting mechanism 42, so as to adjust the angle of the electron microscope 31. The industrial camera 32 is assembled on the electron microscope 31. The industrial camera 32 can display the image under the microscope in real time. For example, the image observed by the electron microscope 31 can be displayed through the display device 6. The user can also observe through the display screen of the computer. If necessary, the recording function can be turned on to record the dynamic process under the electron microscope 31. In addition, the image collected by the industrial camera 32 can be saved to the computer for subsequent analysis and processing. During the subsequent analysis and processing, professional image processing software can also be used on the computer to perform operations such as image enhancement, measurement and calculation on the image to obtain more information.

[0055] As Figure 1 and Figure 7 shown, in this embodiment, the lifting mechanism 42 includes a first connecting block 421. The first connecting block 421 has a first clamping arm 422 and a second clamping arm 423. A first clamping hole is formed between the first clamping arm 422 and the second clamping arm 423. The first clamping hole is sleeved on the column 41. Threaded holes are correspondingly arranged on the first clamping arm 422 and the second clamping arm 423. The first screw 424 can pass through the threaded hole and control the first clamping arm 422 and the second clamping arm 423 to move towards each other, so that the first clamping hole is clamped on the column 41. The column 41 can be installed on the working platform 5 through the pedestal 401. When the first clamping arm 422 and the second clamping arm 423 move along the column 41, the pedestal 401 can limit the extreme descending height of the first clamping arm 422 and the second clamping arm 423, so as to prevent the acquisition device 3 from contacting the working platform 5.

[0056] The first connecting block 421 further includes a third clamping arm 425 and a fourth clamping arm 426. A second clamping hole is formed between the third clamping arm 425 and the fourth clamping arm 426. The rotating seat 43 includes a second connecting block 431. The second connecting block 431 is rotatably installed in the second clamping hole through the connecting shaft 432. The third clamping arm 425 and the fourth clamping arm 426 can clamp the connecting shaft 432 through the cooperation of the threaded hole and the second screw 427.

[0057] The second connecting block 431 has a fifth clamping arm 433 and a sixth clamping arm 434. A third clamping hole is formed between the fifth clamping arm 433 and the sixth clamping arm 434. The third clamping hole can be used to install the electron microscope. The fifth clamping arm 433 and the sixth clamping arm 434 can clamp the electron microscope through the cooperation of the threaded hole and the third screw 435.

[0058] The above structure can correspondingly adjust the height and angle of the electron microscope by appropriately relaxing the clamping force of the two clamping arms on the upright column 41 and the connecting shaft 432.

[0059] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
