DETAILED DESCRIPTION

[0045] The embodiment of the present application discloses a straightening translation device to reduce the frictional resistance when inserting surgical consumables, and facilitate the insertion of subsequent surgical consumables.

[0046] The embodiment of the present application also discloses a push system with the above straightening translation device.

[0047] Hereinafter, the embodiments will be described with reference to the accompanying drawings. In addition, the embodiments shown below do not have any limiting effect on the application content recited in the claims. Furthermore, the entire contents of the configurations represented by the embodiments below are not limited to what is necessary as a solution to the application recited in the claims. It should be noted that, for the convenience of description, only the parts related to the application are shown in the drawings. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0048] ​​Those skilled in the art can understand that the pushing device can assist the doctor to push the pushed member such as a guide wire / catheter to the corresponding thrombus or hemangioma and other patient positions in the patient's blood vessels through the sheath on the patient's body according to the doctor's requirements. The doctor will select the corresponding length of the pushed member according to the specific height, weight and other parameters of the patient. Generally, the selected pushed member will be longer than the actual part needed to enter the patient's blood vessels, so as to facilitate the subsequent connection and use of the pushed member with other equipment. When the pushed member is pushed to the determined patient position of the patient, a part of it will be outside the patient's body, which is usually in a free and scattered curved state and is not easy to be inserted with surgical consumables.

[0049] Based on this, the embodiment of the present application discloses a straightening translation device 300, as shown in Figures 1-3 and Figure 7 The straightening translation device 300 includes a translation base 301, a first adapter support 303, and a translation driving device. The translation base 301 is a supporting device of the straightening translation device 300, which is used to provide an installation basis for the components thereon.

[0050] The translation base 301 can be a plate structure. In order to reduce the mass, a plurality of lightening holes can be formed on the translation base 301 in different areas. Of course, the translation base 301 can also be other structures, and is not limited to a plate body. When the pushing device 100 needs to have a certain height, the translation base 301 can be provided with corresponding supporting legs to increase the height of its upper surface. Of course, the height of the pushing device 100 can also be raised by the first adapter support 303.

[0051] The first adapter support 303 is slidingly fitted on the translation base 301. The sliding range of the first adapter support 303 on the translation base 301 can be designed by those skilled in the art according to the needs to meet the needs of straightening the pushed member. Of course, the sliding range of the first adapter support 303 on the translation base 301 will also be affected by the distance between the straightening translation device 300 and the patient.

[0052] For example, in actual application scenarios, if the doctor generally designs the length of the exposed part of the pushed member outside the patient as m, and the distance between the straightening translation device 300 and the patient is n, then the sliding range of the first adapter support 303 should be greater than m-n to ensure that the exposed part of the pushed member can be effectively straightened.

[0053] Of course, the doctor can also select the length of the pushed member according to the sliding range of the first adapter support 303 when selecting the length of the pushed member, so as to ensure that the exposed part of the pushed member can be effectively straightened.

[0054] The first adapter support 303 is used to fix the pushing device 100, and the pushing device 100 is used to push the pushed member, which can be a catheter and / or a guide wire. The top of the first adapter support 303 can be provided with an adapter plate, and the adapter plate is provided with a fastener hole. The pushing device 100 can be fixed on the adapter plate of the first adapter support 303 through the fastener. It should be noted that the pushing device 100 can also be fixed on the first adapter support 303 through other components, such as a clamping member, a pin member, or even welded on the first adapter support 303, or designed as an integral structure with the first adapter support 303. The specific fixing relationship between the pushing device 100 and the first adapter support 303 is not limited in the embodiment.

[0055] The translation driving device is arranged on the translation base 301 and is used to push and pull the first adapter support 303 to reciprocate. The specific structure type of the translation driving device is not limited in the embodiment, as long as the translation driving device can output a linear driving force and can push and pull the first adapter support 303 to reciprocate.

[0056] The straightening translation device 300 disclosed in the embodiment of the application has the first adapter support 303 that can be pushed and pulled to reciprocate by the translation driving device, and the first adapter support 303 is used to fix the pushing device 100. In use, when the pushing device 100 completes the pushing of the pushed member such as a guide wire / catheter, the first adapter support 303 can be pushed by the translation driving device to drive the pushing device 100 to move away from the patient, until the remaining pushed member outside the patient is arranged in a straight line, and then the action of the translation driving device is stopped, and the pushing device 100 is kept at the position where the pushed member is straightened.

[0057] The translation driving device can be controlled by a doctor or an assistant of the doctor, that is, the doctor or the assistant manually controls the movement of the first adapter support 303, and then the translation driving device is turned off when it is observed that the first adapter support 303 is moved to the position. Specifically, a control part for controlling the action of the translation driving device can be arranged on the actual product, and the control part can include different moving directions, that is, when the control part in the corresponding direction is triggered, the first adapter support 303 can move in the corresponding direction. The triggering mode can be that when the corresponding control part is touched or pressed, the translation driving device drives the first adapter support 303 to move in the corresponding direction, and when the corresponding control part is released, the translation driving device is stopped. Of course, other triggering modes can also be used, and the above-mentioned mode is only a specific example and does not constitute a limitation on the scheme.

[0058] The application can straighten the pushed member remaining outside the patient to facilitate the subsequent surgical consumables to be inserted into the pushed member, reduce the movement friction resistance between the pushed members in the curved state, and improve the stability and good operability of the pushed member in cooperation with the surgical consumables during the operation process.

[0059] As Figures 5-7 shown, the straightening translation device 300 disclosed in the embodiments of the present application can further comprise a second adapter bracket 310 slidingly fitted on the translation base 301, the second adapter bracket 310 being used to fix a receiving device 200, the receiving device 200 being used to receive and release the pushed member. The receiving device 200 is used to release or recover the pushed member such as a guide wire / catheter synchronously with the pushing device 100, so as to achieve stable and reliable pushing of the guide wire / catheter.

[0060] The top of the second adapter bracket 310 can be provided with an adapter plate, and the adapter plate is provided with fastener holes, and the receiving device 200 can be fixed on the adapter plate of the second adapter bracket 310 through the fasteners. It should be noted that the receiving device 200 can also be fixed on the second adapter bracket 310 through other components, such as a clamping member, a pin member, or even can be welded on the second adapter bracket 310, or designed as an integral structure with the second adapter bracket 310, and the specific fixing relationship between the receiving device 200 and the first adapter bracket 303 is not limited in the embodiments.

[0061] It should be noted that the specific structure of the pushing device 100 and the receiving device 200 is not limited in the embodiments, and both of them can be any structure of the pushing device 100 and the receiving device 200 existing in the prior art, and the focus of the embodiments is not the specific structure of the pushing device 100 and the receiving device 200, but the synchronization of the pushing device 100 and the receiving device 200 moving away from the patient through the straightening translation device 300, so as to straighten and tension the pushed member exposed outside the patient's body.

[0062] The first adapter bracket 303 and the second adapter bracket 310 are connected, and the output end of the translation driving device is connected with one of the first adapter bracket 303 and the second adapter bracket 310. In the embodiments, the first adapter bracket 303 and the second adapter bracket 310 are connected, so that the distance between the pushing device 100 and the receiving device 200 is fixed and unchangeable, and the synchronization of movement can be ensured, so that the distance between the pushing device 100 and the receiving device 200 will not change during the movement.

[0063] The output end of the translation driving device is connected with at least one of the first adapter bracket 303 and the second adapter bracket 310, that is, the translation driving device only needs to push and pull one of the first adapter bracket 303 and the second adapter bracket 310, so as to drive the other one to move synchronously.

[0064] Figure 7In the shown solution, the output end of the translation driving device is connected with the second adapter support 310, and of course the output end of the translation driving device can also be connected with the first adapter support 303. In other words, the output end of the translation driving device can also be connected with both the first adapter support 303 and the second adapter support 310.

[0065] In an embodiment of the present application, the first adapter support 303 and the second adapter support 310 can be connected through a connecting rod 308. The first adapter support 303 and the second adapter support 310 can be provided with corresponding mounting holes, and one end of the connecting rod 308 is fixed on the mounting hole of the first adapter support 303 and the other end is fixed on the mounting hole of the second adapter support 310.

[0066] Specifically, the mounting holes on the first adapter support 303 and the second adapter support 310 can be threaded holes, and the rotation directions of the threaded holes on the first adapter support 303 and the second adapter support 310 can be opposite. The two ends of the connecting rod 308 are screw rod portions, and the rotation directions of the screw rod portions at the two ends are also opposite. The screw rod portions at the two ends of the connecting rod 308 are matched with the threaded holes of the first adapter support 303 and the second adapter support 310 respectively. Since the rotation directions of the screw rod portions at the two ends of the connecting rod 308 are opposite, when the connecting rod 308 is rotated in one direction, the screw rod portions at the two ends can be screwed into the corresponding threaded holes respectively, so as to realize the connection between the connecting rod 308 and the first adapter support 303 and the second adapter support 310.

[0067] Of course, the mounting holes on the first adapter support 303 and the second adapter support 310 can also be light holes, or the mounting hole on one of the first adapter support 303 and the second adapter support 310 is a threaded hole, and the mounting hole on the other is a light hole. The two ends of the connecting rod 308 can also be screw rod portions, and the screw rod portions can be directly matched with the threaded holes or matched with the light holes through the cooperation with nuts. For example, two nuts are provided, the screw rod portions pass through the light holes, the two nuts are screwed with the screw rod portions, and the two nuts are clamped on the two sides of the light holes, so as to realize the connection between the screw rod portions and the light holes.

[0068] Of course, the two ends of the connecting rod 308 can also be welded on the first adapter support 303 and the second adapter support 310 respectively. The present embodiment does not limit the connection mode between the connecting rod 308 and the first adapter support 303 and the second adapter support 310, as long as the first adapter support 303 and the second adapter support 310 can be connected and the first adapter support 303 and the second adapter support 310 can be moved synchronously.

[0069] The number of the connecting rod 308 can be one or multiple, and the present embodiment does not limit the actual number of the connecting rod 308, Figure 7 In the shown solution, two connecting rods 308 are provided and symmetrically arranged on the two sides of the translation driving device.

[0070] In an embodiment of the present application, the translation driving device can include a driving motor 305 and a screw mechanism. The driving motor 305 is fixed to the translation base 301, and the screw mechanism includes a screw 311 and a nut 313 in threaded cooperation.

[0071] The screw 311 of the screw mechanism is rotatably supported on the translation base 301 and is in transmission connection with the output shaft of the driving motor 305, and the driving motor 305 drives the screw 311 to rotate. The nut 313 of the screw mechanism is connected to one of the first adapter bracket 303 and the second adapter bracket 310. When the driving motor 305 drives the screw 311 to rotate, the nut 313 cannot rotate with the screw 311 because it is connected to one of the first adapter bracket 303 and the second adapter bracket 310, that is, the rotational freedom of the nut 313 is limited, and it can only move in the axial direction of the screw 311. According to the different rotation directions of the screw 311, the moving directions of the nut 313 are different, and the moving directions of the first adapter bracket 303 and the second adapter bracket 310 are different.

[0072] The screw 311 can be a ball screw with higher transmission efficiency and lower energy consumption. The ball screw replaces the sliding friction of the ordinary screw with rolling friction, which has lower energy consumption. The ball of the ball screw is in point contact with the track, which is uniform in wear and has a service life more than 10 times that of the ordinary screw.

[0073] In actual use, the driving motor 305 can be controlled to output a corresponding rotation direction according to the needs, so as to drive the first adapter bracket 303 and the second adapter bracket 310 to move towards or away from the patient.

[0074] The translation base 301 is provided with a first bearing seat 307 and a second bearing seat 312 at intervals, one end of the screw 311 is supported on the first bearing seat 307, and the other end is supported on the second bearing seat 312. Specifically, the first bearing seat 307 and the second bearing seat 312 can be arranged on the two sides of the second adapter bracket 310, that is, the second adapter bracket 310 is located between the first bearing seat 307 and the second bearing seat 312. The screw 311 passes through the second adapter bracket 310 and is supported on the first bearing seat 307 and the second bearing seat 312, respectively.

[0075] The nut 313 is fixed to the second adapter bracket 310, and the screw 311 passes through the second adapter bracket 310 and is in threaded cooperation with the nut 313 fixed to the second adapter bracket 310. The nut 313 can be directly welded on the second adapter bracket 310, or can be detachably fixed on the second adapter bracket 310 through fasteners, buckles or other connecting members.

[0076] The output shaft of the driving motor 305 is in transmission connection with the screw rod 311 through the shaft coupling 306. That is, in the embodiment, the output shaft of the driving motor 305 is coaxially arranged with the screw rod 311. Of course, the output shaft of the driving motor 305 can also be in transmission connection with the screw rod 311 through other mechanisms, for example, the power transmission of the two can be realized through a gear mechanism.

[0077] In order to reduce the moving speed of the first adapter support 303 and the second adapter support 310, the driving motor 305 can be a reduction motor with a reduction mechanism. Of course, a reducer or a gear mechanism with a reduction function can also be arranged between the driving motor 305 and the screw rod 311.

[0078] In order to improve the smoothness of the first adapter support 303 and the second adapter support 310 during movement, in the embodiment, the translation base 301 is provided with the first sliding part 304, and the extension direction of the first sliding part 304 is parallel to the moving direction of the first adapter support 303 and the second adapter support 310. In other words, the extension direction of the first sliding part 304 can be arranged according to the moving direction required by the first adapter support 303 and the second adapter support 310.

[0079] The first adapter support 303 is provided with the second sliding part 302 which is in sliding cooperation with the first sliding part 304, and the second sliding part 302 can be arranged at the bottom of the first adapter support 303. After the second sliding part 302 is arranged on the first sliding part 304, the first adapter support 303 has a certain gap with the translation base 301, so as to prevent the first adapter support 303 and the translation base 301 from rubbing against each other and increasing the sliding resistance.

[0080] The second adapter support 310 is provided with the third sliding part 309 which is in sliding cooperation with the first sliding part 304, and the third sliding part 309 can be arranged at the bottom of the second adapter support 310. After the third sliding part 309 is arranged on the first sliding part 304, the second adapter support 310 has a certain gap with the translation base 301, so as to prevent the first adapter support 303 and the translation base 301 from rubbing against each other and increasing the sliding resistance.

[0081] In the embodiment, the first sliding part 304 can be a linear guide rail, and the first sliding part 304 can be two parallel and symmetrically arranged on both sides of the translation driving device.

[0082] The second sliding part 302 and the third sliding part 309 are both sliding blocks matched with the linear guide rail. The linear guide rail can be a linear guide rail with a limiting function, so that the sliding block can only slide into the linear guide rail through the end of the linear guide rail, and cannot be matched with the linear guide rail from above the linear guide rail. Therefore, when the sliding block is matched with the linear guide rail, the sliding block cannot be separated from the linear guide rail in the upward direction, so that the first adapter bracket 303 and the second adapter bracket 310 cannot be separated from the translation base 301 in the upward direction.

[0083] For example, the first sliding part 304 can be a dovetail sliding rail with a limiting function upward. Correspondingly, the second sliding part 302 and the third sliding part 309 are both dovetail sliding blocks, and the dovetail sliding blocks are provided with dovetail grooves matched with the tracks on the dovetail sliding rail.

[0084] It should be noted that the first sliding part 304 can also be a linear guide rail with other structures, as long as it can provide a guiding function for the second sliding part 302 and the third sliding part 309 to limit the movement direction of the first adapter bracket 303 and the second adapter bracket 310.

[0085] The second sliding part 302 can be fixed on the first adapter bracket 303 by a fastener, or can be designed as an integral mechanism with the first adapter bracket 303; the third sliding part 309 can be fixed on the second adapter bracket 310 by a fastener, or can be designed as an integral mechanism with the second adapter bracket 310; correspondingly, the first sliding part 304 can be fixed on the translation base 301 by a fastener, or can be designed as an integral mechanism with the translation base 301.

[0086] In an embodiment of the present application, the first sliding part 304 is arranged in parallel in two parts and symmetrically arranged on both sides of the translation driving device. Of course, the first sliding part 304 can also be designed in other quantities, and the positional relationship with the translation driving device is not limited to symmetry.

[0087] In an embodiment of the present application, the straightening translation device 300 can further include a first limit switch 314 and a second limit switch 315 arranged on the translation base 301, and the first adapter bracket 303 is provided with a sensing plate 416. During the movement of the first adapter bracket 303, the sensing plate 416 moves synchronously with the first adapter bracket 303.

[0088] When the first limit switch 314 senses the sensing plate 416, the first adapter bracket 303 is at the first limit position, and when the second limit switch 315 senses the sensing plate 416, the first adapter bracket 303 is at the second limit position. In this embodiment, the first limit switch 314 and the second limit switch 315 are used to limit the two limit positions of the first adapter bracket 303 and the second adapter bracket 310, so that the first adapter bracket 303 and the second adapter bracket 310 can only move between the two limit positions.

[0089] For example, the first limit position is the limit position of the rear end of the first adapter bracket 303, and the second limit position is the limit position of the front end of the first adapter bracket 303. The front end is the end close to the patient, and the rear end is the end away from the patient.

[0090] In use, the first adapter bracket 303 is first moved to the second limit position, that is, the first adapter bracket 303 is moved to the front end. After the pusher 100 completes the pushing of the pushed member such as a guide wire or a catheter, the first adapter bracket 303 can be pushed by the translation driving device to move the pusher 100 in the direction of the first limit position until the pushed member remaining outside the patient is arranged in a straight line. If the first adapter bracket 303 moves to the first limit position, it cannot be guaranteed that the pushed member is arranged in a straight line, and the translation driving device needs to be turned off to prevent the first adapter bracket 303 and the second adapter bracket 310 from being separated from the second adapter bracket 310.
