Description

Technical Field

[0001] This utility model relates to the field of duct pump technology, specifically to a bracket, control device, and duct pump system. Background Technology

[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 patients, and doctors are looking for a rapid, minimally invasive approach to treatment.

[0003] Mechanical circulatory support (MCS) systems and ventricular assist devices (VADs) are increasingly accepted in the treatment of acute heart failure. For example, they are used to stabilize patients following cardiogenic shock in the treatment of acute myocardial infarction (MI) or compensated heart failure, or to provide support during high-risk percutaneous coronary intervention (PCI). One example of an MCS system is a rotary catheter pump 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 heart's pumping function. Other known applications include pumping venous blood from the right ventricle into 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, to stabilize patients before heart transplantation, or for continuous support.

[0005] As disclosed in the known embodiment of CN113856036A, a catheter pump with a small interventional size is provided, which employs an external motor. The general working principle of this catheter pump is as follows: the external motor transmits rotational power to a distal impeller via a drive shaft inserted through the catheter. The impeller's rotation provides flow power to the blood, pumping it from the left ventricle to the aorta. During the power transmission process of the impeller, multiple rotating components exist, such as the drive shaft and proximal and distal bearings supporting the impeller. Therefore, during the catheter pumping process, flushing fluid needs to be injected into the catheter to lubricate and cool these rotating components.

[0006] In the prior art, exemplified by US20210038783A1, the infusion system and control unit are integrated, while the drive motor is separate. Since the infusion system, control unit, and drive motor are the most important reusable components of the catheter pump, they need to be constantly moved when treating different patients. Therefore, not integrating the drive motor with the infusion system and control unit leads to problems such as inconvenience in relocating reusable equipment, loss of parts, and the need for continuous disassembly and reassembly of the drive motor, infusion system, and control unit.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0065] Please see Figures 1 to 7 This utility model provides a conduit pump system, which includes a conduit pump 200. The conduit 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] The working component 220 includes a conduit 221, a drive shaft, a pump head 222, and a coupler 223. The distal end of the conduit 221 is connected to the pump head 222, and the proximal end of the conduit 221 is connected to the coupler 223. The drive shaft passes through the conduit 221, and the distal end of the drive shaft is connected to a fluid delivery element in the pump head 222. When the drive component 210 is connected to the working component 220, the drive component 210 drives the drive shaft to rotate, thereby rotating the fluid delivery element to pump blood.

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

[0068] The fluid delivery element is an impeller, and the pump head 222 also includes a pump housing having an inlet and an outlet, within which the fluid delivery element is housed. Specifically, the main body 211 includes a motor housing and a motor housed within the motor housing. The driving element is driven by the motor. The coupler 223 is detachably connected to the motor, and the driven element is coupled to the driving element to transmit the rotational power of the motor to the drive shaft. The pump head 222 includes a pump housing having an inlet and an outlet and an impeller housed within the pump housing. The impeller is connected to the distal end of the drive shaft to be driven to rotate, drawing blood from the inlet into the pump housing and discharging it from the outlet.

[0069] The pump housing includes a metal lattice support (not shown) made of nickel-titanium alloy and an elastic diaphragm covering the support. The metal lattice of the support has a mesh design, and the diaphragm covers the middle and rear portions of the support. The mesh openings at the front end of the support, not covered by the diaphragm, form an inlet. The rear end of the diaphragm covers the distal end of the conduit 221, and the outlet is an opening formed at the rear end of the diaphragm.

[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, forming a foldable pump head 222 with the aforementioned support and diaphragm made of nickel-titanium shape memory alloy. Alternatively, the pump head 222 can be non-foldable. Correspondingly, the pump casing can be a metal sleeve, preventing radial folding and self-expansion. The impeller is also made of a rigid but biocompatible material.

[0071] The drive shaft includes a flexible shaft and a rigid shaft connected to the distal end of the flexible shaft. The flexible shaft passes through a guide tube 221, and the rigid shaft passes through a hollow channel in the impeller hub. The outer wall of the rigid shaft is fixed to the inner wall of the hollow channel by bonding. The proximal and distal ends of the bracket are connected to a proximal bearing chamber (not shown) and a distal bearing chamber (not shown), respectively, and a proximal bearing and a distal bearing are respectively installed in the proximal and distal bearing chambers. The proximal and distal ends of the rigid shaft pass through the proximal and distal bearings, respectively. In this way, the rigid shaft is supported by two bearings at both ends, and the high rigidity of the rigid shaft allows the impeller to be better held within the pump casing.

[0072] The distal end of the distal bearing chamber is provided with a protective head 224 made of flexible material to avoid damaging the subject's tissues. Specifically, the protective head 224 is supported on the ventricular wall in a non-invasive or non-damaging manner, separating the suction port of the pump head 222 from the ventricular wall, preventing the suction port of the pump head 222 from adhering to the ventricular wall due to the reaction force of the fluid (blood) during operation, thus ensuring the effective pump suction area.

[0073] Coupler 223 and drive assembly 210 are detachably connected, specifically by using a lock nut or a snap-fit ​​connection as provided in US9421311B2. The driven component is coupled to the driving component 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 component and the driving component can use a magnetic coupling method as provided in CN103120810B or CN101820933B, where both the driven component and the driving component are magnets. Alternatively, the driven component and the driving component can also use an eddy current coupling as provided in CN216061675U or CN114452527B, where one of the driven component and the driving component is a magnet and the other is a conductor.

[0074] When the working component 220 is in operation, the working component 220 is connected to the drive 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 drive shaft to rotate. Finally, the drive shaft drives the impeller to rotate at the inlet and outlet.

[0075] The drive assembly 210 also includes a coupling member connected to the proximal end of the motor and extending beyond the proximal end face of the motor housing. This coupling member is used for detachable connection with the coupler 223. The connection between the coupling member and the coupler 223 can be achieved using the scheme described above, and will not be repeated here. The connection or disconnection of the working assembly 220 and the drive assembly 210 can be achieved through the connection or disconnection of the coupling member and the coupler 223.

[0076] In view of the above, the conduit pump system also includes a control device 100 and a bracket 300.

[0077] The control device 100 includes a control host 110 and a bracket 300 mounted on the control host 110. The control host 110 contains a control module for controlling motor operation, including controlling the motor's start / stop and speed control.

[0078] The bracket 300 provides a storage and mounting space for the drive assembly 210. It is understood that the drive assembly 210 has an operating state and a retracted state; in the operating state, the motor is connected to the coupler 223; in the retracted state, the motor is disconnected from the coupler 223, and the drive assembly 210 is supported and limited at the bracket 300, thus achieving the storage and mounting of the drive assembly 210.

[0079] Depending on actual needs, the bracket 300 can be positioned at any location 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 out on one side surface 113 of the control host 110. In this case, the bracket 300 can be positioned on the same side surface 113 of the control host 110 as the display module 120, with the two arranged side by side. Or, as... Figure 6 As shown, the bracket 300 is placed on the side of the display module 120 and 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 can be integrally molded. Alternatively, the bracket 300 and the control host 110 can be separately molded and then connected in a detachable or non-detachable manner.

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

[0082] Please see Figures 1 to 3 The bracket 300 of this utility model includes a base, a support portion, and a winding portion. The support portion is disposed on the base and is used to support the main body 211 of the drive assembly 210 extending along a first preset direction; the winding portion is disposed on the base and is used to wind up the cable 212 of the drive assembly 210 along a second preset direction; wherein the first preset direction and the second preset direction are intersecting, and the included angle between them is not greater than 90°.

[0083] In the technical solution provided by this utility model, 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, so as to avoid problems such as inconvenience of operation and loss of equipment such as reusable drive component 210 during the migration process. The base in the bracket 300 provides mounting support and structural reinforcement for the support and winding parts. By adapting to the shape of the outer wall of the control host 110 of the control device 100, the bracket 300 is more stably installed relative to the control host 110. The support part can effectively support the main body 211 of the limit drive assembly 210, so that the main body 211 extends and is fixed along the first preset direction. The winding part allows the cable 212 in the drive assembly 210 to be wound, 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 settings of the first and second preset directions make it easier for users to perform winding operations and effectively avoid mutual pulling during migration, which could cause damage such as breakage or poor contact of the main body 211 and the cable 212. This helps to achieve good integration of the duct pump system and improves the integration safety and reliability.

[0084] The base is generally designed to be compatible with devices such as the control host 110 used in the bracket application, and to provide sufficient space and structural strength for the installation of the support and winding parts. Its specific design can be tailored to actual needs and is not limited. For example, in one embodiment, the base includes a winding seat 320 for mounting the winding part. The support part includes a support base 310, and the support base 310 and the winding seat 320 can be integrally formed. Alternatively, the support base 310 and the winding seat 320 can be separately formed and then detachably or non-detachably connected. The specific form of the support base 310 and the winding seat 320 is not limited; they can be plate-shaped, block-shaped, or frame-shaped, etc., depending on actual needs. For example... Figures 1 to 3 As shown, the support base 310 is roughly cylindrical in shape, and the winding base 320 is roughly plate-shaped.

[0085] In one embodiment, the support base 310 and the winding base 320, after being integrally formed or separately formed and connected, together define a mounting surface. This mounting surface can be a straight surface, a curved surface with a certain curvature, or a surface with concave and convex structures as needed. Both the support portion and the winding portion are located on this mounting surface, placing them on the same surface. This helps to reduce the operational difficulty of supporting the drive assembly 210 on the bracket 300, while further reducing the molding and processing difficulty of the bracket 300.

[0086] It should be noted that in practical applications, the first and second preset directions can be any directions. Specifically, for example, the second preset direction is a horizontal direction. A horizontal direction is any direction on a horizontal plane. The first preset direction is the direction in which the second preset direction is rotated clockwise to the included angle. The included angle is not less than 20° and not greater than 50°, which effectively separates the support spaces of the main body 211 and the cable 212, and also facilitates 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 horizontally, a front surface 112 formed by rotating the bottom surface 111 clockwise to an angle not exceeding 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 disposed on the front surface 112. Thus, the bracket 300 is more adapted to the outer surface shape of the control host 110, helping to increase the aesthetic appeal of the bracket 300 installed on the control host 110.

[0088] Furthermore, when the control device 100 also includes a display module 120, and the display module 120 is located on the front surface 112, the inclined arrangement of the front surface 112 allows the display surface of the display module 120 to face the user, which is more conducive to the user's viewing and operation of the display module 120. The bracket 300 is located on the side surface 113, which can support and limit the duct pump 200 in its stored state to the side of the control host 110, opposite to the display module 120, thus avoiding interference with the display of the display module 120.

[0089] The support base 310 can be equipped with any suitable support structure to adapt to the structural features of the supported object. There are various specific designs for this support structure, such as a concave structure adapted to a convex structural feature, a convex structure adapted to a concave structural feature, or a magnetic structure adapted to a metal structural feature. Specifically, in one embodiment, the support base 310 has a recessed slot 311. From the bottom of the slot 311 to the opening of the slot 311, the slot 311 gradually extends at an incline towards the side where the winding portion is located. The slot 311 is used for inserting and connecting the main body 211, i.e., the aforementioned support structure adapted to the entire main body 211.

[0090] The internal shape and size of the slot 311 are adapted to the external shape and size of the main body 211, so that when the main body 211 is inserted into the slot 311, the slot 311 can restrict the translational freedom of the main body 211 at least in the direction of its own bottom wall and in the direction of its own side wall.

[0091] The main body 211 may be completely housed within the slot 311, or the main body 211 may be at least partially housed within the slot 311. When the main body 211 is partially housed within the slot 311, if there are no other supporting parts to assist in limiting it, the size and / or weight of the part of the main body 211 housed within the slot 311 may be set to be greater than the part 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 main body 211 may be received within the slot 311, and at least the tail end of the main body 211 may be exposed outside the slot 311, so that the cable 212 can extend outward more smoothly and without obstruction. Specifically, the head end of the main body 211 is provided with a power output shaft 211d, a motor is disposed inside the main body 211, the cable 212 provides power or signal to the motor, the power of the motor is output through the power output shaft 211d, and the slot 311 is used for the insertion and connection of the power output shaft 211d.

[0093] The slot 311 is tilted in the aforementioned direction so that when the main body 211 is inserted into the slot 311, the cable 212 at its end can naturally extend toward the winding seat 320, avoiding the cable 212 having to bend to a certain extent before it can reach the winding seat 320, which would cause damage to the cable 212.

[0094] When the slot 311 extends at an angle in the aforementioned direction, the support base 310 can be configured to also be angled to accommodate the angled extension of the slot 311. In this case, if the display screen of the display module 120 installed on the control host 110 is also angled, the angle of the support base 310 / slot 311 can be set to be substantially parallel to the angle of the display screen, so as to make the overall appearance of the control device 100 more uniform.

[0095] The aforementioned inclined extension direction of slot 311 can be set to be fixed, so that any main body 211, or each insertion and connection of main body 211, can basically ensure that the relative position between cable 212 and winding seat 320 remains fixed. Alternatively, in one embodiment, the support base 310 is rotatably configured relative to the winding seat 320, so that the inclined direction of slot 311 can be adjusted. The support base 310 can achieve relative rotational movement with the winding seat 320 in any suitable manner: specifically, for example, the support base 310 is rotatably mounted on the side surface 113 of the control host 110 via a pivot, while the winding seat 320 is fixedly mounted on the side surface 113 of the control host 110. Alternatively, the parts of the support base 310 and the winding seat 320 that are close to each other can be rotatably connected by a pin, etc.

[0096] The rotation of the support base 310 can be achieved through manual operation by the user. In this case, the bracket 300 may also include an operating component connected to the support base 310. The operating component may be, for example, a handwheel, lever, or button. The user triggers the operation of the operating component to achieve accurate control of the rotation of the support base 310. Alternatively, the rotation of the support base 310 can be achieved through an additional driving device, such as a motor or a combination of a motor and a transmission structure. These are existing technologies and will not be described in detail here.

[0097] Since the orientation of the slot 311 on the support 310 is basically fixed, when the support 310 rotates relative to the winding base 320, the slot 311 rotates synchronously, thereby adjusting the tilt direction of the slot 311. This ultimately changes the relative position between the cable 212 at the tail end of the main body 211 and the winding base 320, meeting different application requirements. Furthermore, by rotating the support 310, the orientation of the slot 311 can be adjusted, allowing the main body 211 to be inserted or removed from any suitable angle or orientation.

[0098] It should be noted that when the support base 310 rotates relative to the winding base 320 to the required angle, the bracket 300 may further include a locking mechanism, which can lock the current rotational position of the support base 310. The locking mechanism achieves the locking purpose, for example, through a fixed connection between the support base 310 and the winding base 320, or through a fixed connection between the support base 310 and the control host 110, facilitating the formation of a relatively stable slot 311 for the main body 211 to be inserted and removed.

[0099] The locking mechanism may include, but is not limited to, magnetic structures, snap-fit ​​structures, adhesive structures, etc.

[0100] Based on any of the above embodiments, further, the support base 310 is provided with an interference structure within the slot 311. When the main body 211 is inserted into the slot 311, interference occurs between the interference structure and the main body 211, thereby restricting the main body 211 from dislodging outward from 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 bottom wall and in any direction of its own side wall. The further provided interference structure can assist in limiting the main body 211, for example, in the direction from the bottom wall of the slot 311 to the opening of the slot 311, increasing the stability of the insertion connection of the main body 211 within the slot 311.

[0101] The specific design of the interference structure is not limited and can include, but is not limited to, one or more of the following methods: magnetic attraction, suction cup, snap-fit, and adhesive bonding. For example, in one embodiment, the support base 310 has a clearance hole 311a on the sidewall of the slot 311. The interference structure includes a snap-fit ​​member 312, which is elastically movable. When the main body 211 is inserted into the slot 311, the snap-fit ​​member 312 engages with the corresponding slot 211a on the outer surface of the main body 211. The clearance hole 311a is located on the sidewall of the slot 311 and can be a through hole or a blind hole. The clearance hole 311a provides sufficient space for the snap-fit ​​member 312 to move elastically. The fastener 312 generally includes an elastic arm protruding from any hole wall of the clearance hole 311a, and an elastic latching protrusion protruding from the side of the elastic arm facing the main body 211. The surface of the elastic latching protrusion facing the main body 211 is generally set as a slope to facilitate fastening connection with the latching groove 211a provided on the main body 211.

[0102] Furthermore, the free ends of the latching member 312, both facing and opposite to the main body 211, are set as inclined surfaces. That is, the side surface 113 of the support arm opposite to the latching protrusion is further set as an inclined surface. Thus, the support arm has a degree of freedom of deformation in the directions approaching and away from the main body 211, which helps to fasten and fix the main body 211 to the latching groove 211a without locking it in place, facilitating quick removal of the main body 211 by external force when needed.

[0103] It is understandable that the aforementioned snap fastener 312 can be replaced by, for example, the ball locking scheme in existing technologies CN113464805A or CN116807805A, without limitation.

[0104] Furthermore, in one embodiment, the support portion further includes a support 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 support member 313 mainly supports the parts of the main body 211 other than the power output shaft 211d. The support member 313 includes a first support plate 313a and a second support plate 313b. The first support plate 313a extends from the opening of the slot 311 along the depth direction of the slot 311; the second support plate 313b extends from one side of the first support plate 313a along the width direction of the slot 311. It can be understood that the outer surface of the main body 211 includes a first sidewall 211b and a second sidewall 211c connected to each other. The first support plate 313a can support and abut against the first sidewall 211b, and the second support plate 313b can support and abut against the second sidewall 211c. The first support plate 313a and the second support plate 313b are roughly L-shaped and can be directly connected or connected by a bending transition through a connecting plate. The first support plate 313a and the second support plate 313b can be integrally formed or separately formed and then connected in a detachable or non-detachable manner.

[0105] Further, in one embodiment, the support member 313 further includes a first buffer pad 313c and a second buffer pad 313d. The first buffer pad 313c is laid on the side surface 113 of the first support plate 313a facing the slot 311; the second buffer pad 313d is laid on the side surface 113 of the second support plate 313b facing the slot 311; wherein the surface shapes of the first buffer pad 313c and the second buffer pad 313d are adapted to the shape 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 or sponge. By setting the surface shapes of the first buffer pad 313c and the second buffer pad 313d to be adapted to the shape of the corresponding side surface 113 of the main body 211. That is, the surface shape of the first buffer pad 313c is adapted to the surface shape of the first sidewall 211b; the surface shape of the second buffer pad 313d is adapted to the surface shape of the second sidewall 211c, so that the first buffer pad 313c and the first sidewall 211b, and the second buffer pad 313d and the second sidewall 211c are more compatible and can be stably abutted.

[0106] For example, when the first sidewall 211b is a flat wall surface, the first buffer pad 313c is also set to a flat surface; when the second sidewall 211c is a concave arc surface, the second buffer pad 313d is set to a convex arc surface.

[0107] It is understandable that the inclined extension of the slot 311, the setting of the latch 312, and the cooperative setting of the support 313 help to achieve good fixation of the drive assembly 210. Furthermore, it allows the bracket 300 and the drive assembly 210 to better adapt to the shapes of the control host 110 and the display module 120, minimizing the protrusion of the bracket 300 and the drive assembly 210 from the outline of the control host 110, thus improving the integration of the drive assembly 210's storage and fixation. Compared to a solution where it is inserted vertically into the slot 311, the inclined setting lowers the overall center of gravity of the drive assembly 210, resulting in better stability after fixation. Moreover, the cable 212 is connected to the tail end of the main body 211, with the main body 211 tilted towards the winding base 320, which reduces the bending angle of the cable 212 and minimizes cable 212 bending damage.

[0108] Based on any of the above embodiments, please refer to... Figures 1 to 5The winding base 320 is provided with a winding component and a clamping component 324. The winding component is used for winding the cable 212, and the clamping component 324 is used to clamp and limit the end of the cable 212 to the winding base 320. The winding component and the clamping component 324 together constitute the winding part. The winding component allows the cable 212 to be wound, which helps to neatly wind cables 212 of any length at the winding component, reducing the space occupied by the cable 212 and lowering the probability of tangling and knotting. The clamping component 324 can clamp and fix the end of the cable 212, preventing the cable 212 from coming loose and causing the cable 212 to become unwound from the winding component.

[0109] Furthermore, in one embodiment, two winding members are spaced apart in a first direction, one near and one far from the support base 310. Each winding member includes a winding protrusion 323a protruding from the winding base 320 and a pressure plate 323b protruding laterally from the free end of the winding protrusion 323a. The winding protrusion 323a is generally cylindrical, which can avoid forming sharp edges that could cause stress concentration damage to the cable 212. The pressure plate 323b can press any partially loosened cable 212 between the control host 110 and the pressure plate 323b. The pressure plate 323b and the winding protrusion 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 pressure plates 323b of the two winding members are arranged in opposite directions, which helps to increase the pressure area range of the two winding members when the cable 212 is loosened. And / or in one embodiment, the clamping member 324 is disposed between the two winding members, so that the end of the cable 212 is stored between the two winding members, which can make full use of the space between the two winding members and avoid the end of the cable 212 being pulled and bent excessively.

[0111] Furthermore, in one embodiment, two winding members are spaced apart in a first direction, one near and one far from the support 310, and are respectively a near-end winding member 321 and a far-end winding member 322. The bracket 300 has a reference projection surface extending along the first direction. The support 310 is recessed with a slot 311. In the direction from the bottom of the slot 311 to the opening of the slot 311, the slot 311 gradually extends at an inclination towards the side where the winding portion is located. The depth of the slot 311 is set such 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 311 on the reference projection surface is not far from the far-end winding member 322. Further, in one embodiment, the orthographic projection of the end of the main body 211 extending out of the slot 311 on the reference projection surface is not far from the near-end winding member 321. This helps prevent the cable 212 from needing to be rewound, forming a large bend, increasing the damage to the cable 212, and increasing the difficulty of the winding operation.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
