Description

Technical Field

[0001] The utility model relates to the technical field of catheter pumps, and specifically to a bracket, a control device and a catheter pump system. Background Art

[0002] Heart disease is a health problem with a high mortality rate, and doctors are increasingly using mechanical circulatory support systems to treat heart failure. Treatment of acute heart failure requires a device that can quickly provide support to the patient, and doctors want to be able to deploy treatment options quickly and minimally invasively.

[0003] Mechanical circulatory support (MCS) systems and ventricular assist devices (VADs) are gaining increasing acceptance in the treatment of acute heart failure. For example, in the treatment of acute myocardial infarction (MI) or compensated heart failure, to stabilize patients after cardiogenic shock, or to support patients during high-risk percutaneous coronary intervention (PCI). An example of an MCS system is a rotary catheter pump that is placed percutaneously via a catheter.

[0004] In conventional methods, a catheter pump is inserted into the body and connected to the cardiovascular system (e.g., connecting the left ventricle and the ascending aorta) to assist the pump function of the heart. Other known applications include pumping venous blood from the right ventricle to the pulmonary artery to support the right side of the heart. Typically, acute circulatory support devices are used to reduce the load on the myocardium for a period of time, stabilize the patient before heart transplantation, or for continuous support.

[0005] For example, a known embodiment with publication number CN113856036A provides a catheter pump that can achieve a small intervention size, that is, an external motor is used. The general working principle of the catheter pump is: the external motor transmits the rotational power to the distal impeller through the drive shaft inserted in the catheter, and the rotation of the impeller provides flow power to the blood, pumping the blood from the left ventricle to the aorta. During the power transmission process of the impeller, due to the presence of multiple rotating parts, such as the drive shaft, and the proximal and distal bearings supporting the impeller, etc. Therefore, during the catheter pump process, it is necessary to inject flushing fluid into the catheter to lubricate and cool the above-mentioned rotating parts.

[0006] In the prior art with publication number US20210038783A1 as an example, the infusion system and the control host are integrated, while the drive motor is separately provided. Since the infusion system, the control host and the drive motor are the most important reusable devices in the catheter pump, they need to be constantly migrated when rescuing different patients. Therefore, if the drive motor is not integrated with the infusion system and the control host, it will cause problems such as inconvenient migration of reusable equipment, loss of equipment parts, and constant disassembly and installation of the drive motor, infusion system and control host.

[0062] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0063] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0064] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0065] See also Figures 1 to 7 The utility model provides a catheter pump system, which includes a catheter pump 200. The catheter pump 200 generally includes a drive assembly 210 and a working assembly 220. The drive assembly 210 and the working assembly 220 are generally detachably connected.

[0066] Among them, the working component 220 includes a catheter 221, a driving shaft, a pump head 222 and a coupler 223; the distal end of the catheter 221 is connected to the pump head 222; the proximal end of the catheter 221 is connected to the coupler 223; the driving shaft is inserted into the catheter 221, and the distal end of the driving shaft is connected to the fluid delivery element in the pump head 222; when the driving component 210 is connected to the working component 220, the driving component 210 drives the driving shaft to rotate, and drives the fluid delivery element to rotate to pump blood.

[0067] The driving assembly 210 includes a main body 211, a cable 212 and an active member, and the working assembly 220 includes a driven member. When the driving assembly 210 is connected to the working assembly 220, the active member is coupled with the driven member to transmit the rotational power to the driving shaft.

[0068] The fluid delivery element is an impeller, and the pump head 222 also includes a pump housing, the pump housing has an inlet and an outlet, and the fluid delivery element is accommodated in the pump housing. Specifically, the main body 211 includes a motor housing and a motor accommodated in the motor housing. The active member is driven by the motor. The coupler 223 is detachably connected to the motor, and the driven member is coupled to the active member to transmit the rotational power of the motor to the drive shaft. The pump head 222 includes a pump housing with an inlet and an outlet and an impeller accommodated in the pump housing, and the impeller is connected to the distal end of the drive shaft so as to be driven to rotate and suck blood from the inlet into the pump housing and discharge it from the outlet.

[0069] The pump housing includes a metal lattice support (not shown) made of nickel and titanium alloy and an elastic coating covering the support. The metal lattice of the support has a mesh design, the coating covers the middle and rear end of the support, and the mesh of the front end of the support not covered by the coating forms an inlet. The rear end of the coating is coated on the outside of the distal end of the catheter 221, and the outlet is an opening formed at the rear end of the coating.

[0070] The impeller includes a hub and blades supported on the outer wall of the hub. The blades can be made of a flexible material, and then form a foldable pump head 222 with the above-mentioned bracket and coating made of nickel and titanium memory alloy. Of course, the pump head 222 can also be non-foldable. Correspondingly, the pump housing can be a metal sleeve that cannot radially fold and self-expand. The impeller is also made of a hard but biocompatible material.

[0071] The drive shaft includes a bendable soft shaft and a hard shaft connected to the distal end of the soft shaft, the soft shaft is inserted into the conduit 221, the hard shaft is inserted into the hollow channel of the impeller hub, and the outer wall of the hard shaft is fixed to the inner wall of the hollow channel by bonding. The proximal and distal ends of the bracket are respectively connected to the proximal bearing chamber (not shown) and the distal bearing chamber (not shown), and the proximal bearing chamber and the distal bearing chamber are respectively provided with a proximal bearing and a distal bearing. The proximal and distal ends of the hard shaft are respectively inserted into the proximal bearing and the distal bearing. In this way, the two ends of the hard shaft are supported by two bearings, and the higher rigidity of the hard shaft can make the impeller better kept in the pump housing.

[0072] The distal end of the distal bearing chamber is provided with a protective head 224 made of a flexible material so as not to harm the tissue of the subject. Specifically, the protective head 224 is supported on the inner wall of the ventricle in a non-invasive or non-destructive manner, separating the suction port of the pump head 222 from the inner wall of the ventricle, preventing the suction port of the pump head 222 from being attached to the inner wall of the ventricle due to the reaction force of the fluid (blood) during the operation of the pump head 222, thereby ensuring the effective area of ​​the pump suction.

[0073] The coupler 223 and the drive assembly 210 are detachably connected, and the specific connection method can adopt a locking nut or a snap connection provided by US9421311B2. The driven member is coupled to the active member to transmit the rotational power when the motor is turned on to the drive shaft, thereby driving the impeller to rotate and pump blood. The driven member and the active member can adopt a magnetic coupling method such as that provided by CN103120810B or CN101820933B, that is, the driven member and the active member are both magnets. Alternatively, the driven member and the active member can also adopt an eddy current coupling (Eddy Current Coupling) provided by CN216061675U or CN114452527B, that is, one of the driven member and the active member is a magnet and the other is a conductor.

[0074] When the working component 220 is operated, the working component 220 is connected to the driving component 210 through the coupler 223, the motor drives the active component to rotate, and the driven component coupled with the active component drives the driving shaft to rotate, and finally the driving shaft drives the impeller to rotate the inlet and outlet.

[0075] The driving assembly 210 further includes a coupling component connected to the proximal end of the motor and extending beyond the proximal end surface of the motor housing, and the coupling component is used to be detachably connected to the coupler 223. The connection between the coupling component and the coupler 223 can be achieved by means of the above-mentioned solution, which will not be described in detail. The connection or disassembly of the working assembly 220 and the driving assembly 210 can be achieved by connecting or disassembling the coupling component and the coupler 223.

[0076] In view of the above, in addition, the catheter pump system further includes a control device 100 and a bracket 300 .

[0077] The control device 100 includes a control host 110 and a bracket 300 disposed on the control host 110. A control module is installed inside the control host 110, and the control module is used to control the operation of the motor, including controlling the start and stop of the motor and the speed control.

[0078] The bracket 300 can be used to store and install the drive assembly 210. It can be understood that the drive assembly 210 has a working state and a storage state; when in the working state, the motor is connected to the coupler 223; when in the storage state, the motor is disconnected from the coupler 223, and the drive assembly 210 is supported and limited at the bracket 300 to achieve the storage and installation of the drive assembly 210.

[0079] According to actual needs, the bracket 300 can be set at any position on the control host 110. For example, in one embodiment, when the control device 100 also includes a display module 120, the display screen in the display module 120 is spread on a side surface 113 of the control host 110. In this case, the bracket 300 can be set to be placed on the same side surface 113 of the control host 110 as the display module 120, and the two can be arranged side by side. Figure 6 As shown, the bracket 300 is placed beside the display module 120 and located on the other side surface 113 of the control host 110, so that the bracket 300 and the display module 120 are kept as independent as possible and do not interfere with each other during operation.

[0080] The bracket 300 and the control host 110 may be integrally formed, or the bracket 300 and the control host 110 may be separately formed and then connected detachably or non-detachably.

[0081] The structure of the bracket 300 will be specifically described below with reference to the accompanying drawings.

[0082] See also Figures 1 to 3 The bracket 300 of the utility model includes a base, a support portion and a winding portion. The support portion is arranged on the base, and is used to support the main body 211 of the driving assembly 210 to extend along a first preset direction; the winding portion is arranged on the base, and is used to wind up the cable 212 of the driving assembly 210 along a second preset direction; wherein the first preset direction and the second preset direction are arranged to be cross-arranged, and the angle between the two is not greater than 90°.

[0083] In the technical solution provided by the present invention, the bracket 300 is applied to the control device 100, which can support and limit the drive component 210 in the storage state on the control host 110 of the control device 100, thereby avoiding problems such as inconvenient operation and loss of equipment such as reusable drive components 210 during the migration process. The base in the bracket 300 provides installation support and structural reinforcement for the support part and the winding part, and by adapting to the outer wall shape of the control host 110 of the control device 100, the installation of the bracket 300 relative to the control host 110 is more stable; the support part can effectively support the main body 211 of the limit drive component 210, so that the main body 211 extends and is fixed along the first preset direction; the winding part can be used for winding the cable 212 part in the drive component 210, providing a relatively good storage environment for the cable 212, so that the position of the cable 212 relative to the main body 211 is fixed and safe; the specific setting of the first preset direction and the second preset direction makes it easier for users to perform winding operations, and effectively avoids mutual pulling during the migration process, resulting in damage such as breakage and poor contact of the main body 211 and the cable 212, which helps to achieve good integration of the catheter pump system and improve integrated safety and reliability.

[0084] The base is generally configured to be adaptable to be installed on the application of the bracket, such as the control host 110, and can provide sufficient space and structural strength for the support part and the winding part to be installed. The specific scheme can be specifically designed according to actual needs without limitation. For example, in one embodiment, the base includes a winding seat 320, and the winding seat 320 is for the winding part to be installed. The support part includes a support seat 310, and the support seat 310 and the winding seat 320 can be an integrally formed setting. Alternatively, the support seat 310 and the winding seat 320 can be separately formed and then detachably or non-detachably connected. The specific form of the support seat 310 and the winding seat 320 is not limited, and can be set to a plate, block or frame shape according to actual needs. For example Figures 1 to 3 As shown, the support seat 310 is roughly in the shape of a cylindrical block, and the winding seat 320 is roughly in the shape of a plate.

[0085] In one embodiment, the support seat 310 and the winding seat 320 jointly define a mounting surface after being integrally formed or separately formed and connected. The mounting surface of the base may be a straight surface, a curved surface with a certain curvature, or a concave-convex surface with a concave-convex structure according to actual needs. The support portion and the winding portion are both arranged at the mounting surface, so that the support portion and the winding portion are on the same surface, which helps to reduce the difficulty of operating the drive assembly 210 supported on the bracket 300, while further reducing the difficulty of molding and processing of the bracket 300.

[0086] It should be noted that, in actual application, the first preset direction and the second preset direction can be any direction. For example, the second preset direction is a horizontal direction. The horizontal direction is any direction on a horizontal plane. The first preset direction is the direction of the second preset direction rotated clockwise to the angle. The angle is not less than 20° and not more than 50°, which can effectively separate the support spaces of the main body 211 and the cable 212, and facilitate the winding operation of the cable 212.

[0087] Based on this, when the bracket 300 is specifically applied to the control host 110, in one embodiment, the control host 110 has a bottom surface 111 extending in the horizontal direction, a front surface 112 formed by rotating the bottom surface 111 in the clockwise direction to an angle not greater than 90°, and two side surfaces 113 connecting the bottom surface 111 and the front surface 112; the second preset direction is parallel to the bottom surface 111, the first preset direction is parallel to the front surface 112, and the display module 120 of the control host 110 is arranged on the front surface 112. In this way, the arrangement of the bracket 300 is more adapted to the outer surface shape of the control host 110, which helps to increase the aesthetics of the installation of the bracket 300 on the control host 110.

[0088] Furthermore, when the control device 100 further includes a display module 120, and the display module 120 is disposed on the front surface 112, the display surface of the display module 120 faces the user by virtue of the tilted setting of the front surface 112, which is more helpful for the user to view and operate the display module 120. The bracket 300 is disposed on the side surface 113, and can support and limit the catheter pump 200 in the storage state to the side of the control host 110, which is not in the same plane as the display module 120, so as to avoid interference with the display of the display module 120.

[0089] The support seat 310 may be provided with any suitable support structure adapted to the structural features of the supported object. There are many specific schemes for the support structure, which may be a concave structure adapted to the convex structural features, a convex structure adapted to the concave structural features, a magnetic structure adapted to the metal structural features, etc. Specifically, for example, in one embodiment, the support seat 310 is provided with a slot 311, and in the direction from the bottom of the slot 311 to the notch of the slot 311, the slot 311 gradually extends in an inclined manner toward the side where the winding portion is located; the slot 311 is used for the main body 211 to be inserted and connected, that is, the above-mentioned support structure adapted to the whole of the main body 211.

[0090] The inner shape and size of the slot 311 are adapted to the outer shape and size of the main body 211, so that when the main body 211 is inserted into the connecting slot 311, the slot 311 can at least limit the translational freedom of the main body 211 toward its own bottom wall and toward any side wall of its own.

[0091] The main body 211 may be completely received in the slot 311, or the main body 211 may be at least partially received in the slot 311. When the main body 211 is partially received in the slot 311, if there is no other support part to assist in limiting the position, the size and / or weight of the portion of the main body 211 received in the slot 311 may be set as much as possible to be larger than the portion of the main body 211 extending out of the slot 311.

[0092] When the main body 211 is defined to have a head end and a tail end, and the cable 212 is connected to the tail end of the main body 211, at least the head end of the optional main body 211 is accommodated in the slot 311, and at least the tail end of the main body 211 is exposed outside the slot 311, so that the cable 212 can be more smoothly and unhindered to extend outward. Specifically, the head end of the main body 211 is convexly provided with a power output shaft 211d, and a motor is arranged inside the main body 211. The cable 212 provides power or signal to the motor, and the power of the motor is output through the power output shaft 211d. The slot 311 is used for the power output shaft 211d to be inserted and connected.

[0093] The slot 311 extends obliquely in the above-mentioned direction, so that when the main body 211 is inserted into the connecting slot 311, the cable 212 at its tail end can naturally extend toward the winding seat 320, avoiding the cable 212 from being damaged due to the need to bend to a certain extent before being directed toward the winding seat 320.

[0094] When the slot 311 is extended in the above-mentioned direction, the support base 310 can be arranged to be inclined to adapt to the inclined extension of the slot 311. At this time, if the display screen of the display module 120 arranged on the control host 110 is also inclined, the inclined direction of the support base 310 / slot 311 can be arranged to be substantially parallel to the inclined direction of the display screen, so that the overall appearance structure of the control device 100 is more uniform.

[0095] The above-mentioned inclined extension direction of the slot 311 can be set to be fixed, so that any main body 211, or each insertion and connection of the main body 211, can basically ensure that the relative position between the cable 212 and the winding seat 320 is fixed. Or further, in one embodiment, the support seat 310 is rotatably arranged relative to the winding seat 320, so that the inclined direction of the slot 311 can be movably adjusted. The support seat 310 can achieve relative rotation with the winding seat 320 in any suitable manner: for example, the support seat 310 is rotatably mounted on the side surface 113 of the control host 110 through a rotating shaft, and the winding seat 320 is fixedly mounted on the side surface 113 of the control host 110. Or the parts of the support seat 310 and the winding seat 320 that are close to each other are rotatably connected through a pin body, etc.

[0096] The rotation of the support base 310 can be realized by manual operation of the user. In this case, the bracket 300 can also include an operating component connected to the support base 310, such as a hand wheel, a lever, a button, etc. The user triggers the operation of the operating component to achieve accurate operation and control of the rotation of the support base 310. Alternatively, the rotation of the support base 310 can be realized by an additionally provided drive device, such as a motor, or a combination of a motor and a transmission structure, which are all existing technologies and will not be described in detail here.

[0097] Since the position of the slot 311 on the support base 310 is basically fixed, when the support base 310 rotates relative to the winding base 320, the slot 311 can be driven to rotate synchronously, and then the tilt direction of the slot 311 is adjusted accordingly, and finally the relative position between the cable 212 at the tail end of the main body 211 and the winding base 320 is changed to meet different application requirements. In addition, by rotating the support base 310 to adjust the notch direction of the slot 311, the main body 211 can be plugged in and out from any suitable angle or position.

[0098] It should be noted that when the support base 310 rotates relative to the winding base 320 to a desired angle, the bracket 300 may be further provided with a locking mechanism, which can lock the current rotational orientation of the support base 310. The locking mechanism achieves the locking purpose, for example, by a fixed connection between the support base 310 and the winding base 320, or by a fixed connection between the support base 310 and the control host 110, so as to facilitate the formation of a relatively stable slot 311 for the main body 211 to be plugged in and out.

[0099] The locking mechanism may be, but is not limited to, a magnetic structure, a snap-fit ​​structure, an adhesive structure, etc.

[0100] Based on any of the above embodiments, further, the support seat 310 is provided with an interference structure in the slot 311. When the main body 211 is inserted and connected with the slot 311, the interference structure and the main body 211 interfere with each other to limit the main body 211 from slipping out of the slot 311; the interference structure constitutes the support portion. As can be seen from the above, the slot 311 can limit the main body 211 in the direction of its own slot bottom wall and any direction of its own slot side wall. And by further providing an interference structure, the main body 211 can be assisted in limiting the direction from the slot bottom wall of the slot 311 to the slot opening of the slot 311, for example, to increase the stability of the insertion connection of the main body 211 in the slot 311.

[0101] The specific scheme of the interference structure is not limited, and may include but is not limited to one or more of the following methods, such as magnetic fixation by a magnetic structure, adsorption fixation by a suction cup structure, buckle fixation by a snap structure, and adhesive fixation by an adhesive structure. For example, in one embodiment, the support seat 310 is provided with an avoidance hole 311a on the side wall of the slot 311, and the interference structure includes a snap member 312. The snap member 312 can be elastically movable. When the main body 211 is inserted and connected with the slot 311, the snap member 312 is buckled and connected with the slot 211a provided on the corresponding outer surface of the main body 211. The avoidance hole 311a is provided on the side wall of the slot 311, and may be a through hole or a blind hole. The setting of the avoidance hole 311a reserves sufficient elastic activity space for the snap member 312. The buckle 312 may generally include an elastic arm protruding from any hole wall of the avoidance hole 311a, and an elastic clamping protrusion protruding from the side of the elastic arm facing the main body 211. The surface of the elastic clamping protrusion facing the main body 211 is generally set as an inclined surface, which is convenient for buckling and connecting with the clamping groove 211a set on the main body 211.

[0102] Furthermore, the free end of the buckle 312 is provided with inclined surfaces on both sides 113 facing and away from the main body 211. That is, the side surface 113 of the arm facing away from the clamping protrusion is further provided with an inclined surface, so that the arm has the degree of freedom of deformation in the direction of approaching and moving away from the main body 211, which is helpful for buckling and fixing the clamping slot 211a of the main body 211, and will not be locked with the clamping slot 211a, so that the main body 211 can be quickly taken out by external force when needed.

[0103] Of course, it is understandable that the above-mentioned latch 312 can also be replaced by, for example, the ball locking solution in the prior art CN113464805A or CN116807805A, without limitation.

[0104] In addition, in one embodiment, the support portion further includes a supporting member 313 protruding from the outer side of the slot 311. When the main body 211 is provided with a power output shaft 211d as described above, the supporting member 313 mainly supports the parts of the main body 211 other than the power output shaft 211d. The supporting member 313 includes a first supporting plate 313a and a second supporting plate 313b. The first supporting plate 313a is formed by extending from the notch of the slot 311 along the slot depth direction of the slot 311; the second supporting plate 313b is formed by extending from one side of the first supporting plate 313a along the slot width direction of the slot 311. It can be understood that the outer surface of the main body 211 includes a first side wall 211b and a second side wall 211c connected to each other. The first supporting plate 313a can support and abut the first side wall 211b, and the second supporting plate 313b can support and abut the second side wall 211c. The first supporting plate 313a and the second supporting plate 313b are generally L-shaped, and can be directly connected or connected by a connecting plate. The first supporting plate 313a and the second supporting plate 313b can be integrally formed, or can be separately formed and then connected in a detachable or non-detachable manner.

[0105] Furthermore, in one embodiment, the supporting member 313 further includes a first buffer pad 313c and a second buffer pad 313d. The first buffer pad 313c is laid on a side surface 113 of the first supporting plate 313a facing the slot 311; the second buffer pad 313d is laid on a side surface 113 of the second supporting plate 313b facing the slot 311; wherein the surface shapes of the first buffer pad 313c and the second buffer pad 313d are both suitable for the shape setting of the corresponding side surface 113 of the main body 211. The first buffer pad 313c and the second buffer pad 313d are made of elastic materials such as rubber and sponge. By setting the surface shapes of the first buffer pad 313c and the second buffer pad 313d, they are both suitable for the shape setting of the corresponding side surface 113 of the main body 211. That is, the surface shape of the first buffer pad 313c is suitable for the surface shape setting of the first side wall 211b; the surface shape of the second buffer pad 313d is suitable for the surface shape setting of the second side wall 211c, so that the first buffer pad 313c and the first side wall 211b, and the second buffer pad 313d and the second side wall 211c are more adapted and can be firmly abutted.

[0106] For example, when the first side wall 211b is a straight wall surface, the first buffer pad 313c is also configured as a straight surface; when the second side wall 211c is a concave arc surface, the second buffer pad 313d is configured as a convex arc surface.

[0107] It can be understood that the inclined extension of the slot 311, the setting of the snap member 312 and the matching setting of the supporting member 313 are helpful to achieve good fixation of the drive assembly 210. And make the bracket 300 and the drive assembly 210 better adapt to the shape of the control host 110 and the display module 120, so that the bracket 300 and the drive assembly 210 protrude the outline of the control host 110 as little as possible, and improve the integration of the storage and fixation of the drive assembly 210. Compared with the solution of inserting it into the slot 311 in a vertical form, the inclined setting can lower the overall center of gravity of the drive assembly 210, and the stability of the drive assembly 210 after being fixed is better. In addition, the cable 212 is connected to the tail end of the main body 211, so that the main body 211 is tilted and fixed toward the winding seat 320, which can reduce the bending angle of the cable 212 and reduce the bending damage of the cable 212.

[0108] Based on any of the above embodiments, please combine Figures 1 to 5The winding seat 320 is provided with a winding piece and a clamping piece 324. The winding piece is used for winding the cable 212, and the clamping piece 324 is used for clamping the end of the cable 212 to the winding seat 320; the winding piece and the clamping piece 324 together constitute the winding part. The winding piece can be used for winding the cable 212, which helps cables 212 of any length to be neatly wound at the winding piece, reduces the space occupied by the cable 212, and reduces the probability of entanglement and knotting of the cable 212. The clamping piece 324 can clamp and fix the end of the cable 212 to prevent the end of the cable 212 from loosening, which causes the cable 212 to loosen on the winding piece.

[0109] Furthermore, in one embodiment, two winding members are arranged at intervals in a first direction close to and away from the support seat 310, and each winding member includes a winding boss 323a protruding from the winding seat 320, and a wire pressing plate 323b protruding laterally from the free end of the winding boss 323a. The winding boss 323a is roughly cylindrical, which can avoid the formation of sharp edges and corners to cause stress concentration damage to the cable 212. The wire pressing plate 323b can press the partially loosened cable 212 between the control host 110 and the wire pressing plate 323b. The wire pressing plate 323b and the winding boss 323a can be integrally formed, or they can be separately formed and then connected in a detachable or non-detachable manner.

[0110] Based on the above, in one embodiment, the protruding directions of the wire pressing plates 323b of the two winding members are arranged in opposite directions, which helps to increase the wire pressing area range of the two winding members as a whole when the cable 212 is wound and loosened. And / or in one embodiment, the clamping member 324 is arranged between the two winding members, so that the wire ends of the cable 212 are stored between the two winding members, which can fully utilize the space between the two winding members and prevent the wire ends of the cable 212 from being pulled and bent significantly.

[0111] In addition, in one embodiment, two winding members are arranged at intervals in the first direction close to and away from the support seat 310, and are respectively a proximal winding member 321 and a distal winding member 322, and the bracket 300 has a reference projection surface extending along the first direction; the support seat 310 is recessed with a slot 311, and in the direction from the bottom of the slot 311 to the slot opening of the slot 311, the slot 311 gradually extends in an inclined manner toward the side where the winding portion is located, and the slot depth of the slot 311 is set so that when the main body 211 is inserted and connected, the orthographic projection of the end of the main body 211 extending out of the slot opening of the slot 311 on the reference projection surface is not far from the distal winding member 322. Further, in one embodiment, the orthographic projection of the end of the main body 211 extending out of the slot opening of the slot 311 on the reference projection surface is not far from the proximal winding member 321. This helps prevent the cable 212 from needing to be wound back, forming a larger bend, increasing damage to the cable 212, and increasing the difficulty of the winding operation.

[0112] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
