Description

Technical Field

[0001] This application relates to the field of medical device technology for endoscopic minimally invasive surgery, and in particular to an electrically driven treatment device. Background Technology

[0059] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0060] like Figures 1 to 18 As shown, the electrically driven therapeutic device provided in this application includes: a mounting housing 10, a suture seat 20, an arc-shaped suture needle 30, a stator 40, a rotor 50, and a snap-fit ​​component 60. It should be noted that the electrically driven therapeutic device includes a micro motor. The stator 40 and rotor 50 of the micro motor are assemblies, including, for example, a housing 12, brushes, and a commutator, etc., belonging to a fixed existing motor structure, and will not be further described here. Furthermore, the naming of the stator 40 and rotor 50 is relative; for a linear motor, they are respectively named primary and secondary. The suture seat 20 is connected to the mounting housing 10 and located at one end of the mounting housing 10. The suture seat 20 is provided with a suture groove 21 and an arc-shaped suture hole 22. The suture groove 21 is configured to accommodate human tissue.

[0061] The arc-shaped suture needle 30 is positioned inside the arc-shaped suture hole 22 and can slide within the arc-shaped suture hole 22.

[0062] The stator 40 is fixed inside the mounting housing 10.

[0063] The rotor 50 is disposed inside the mounting housing 10 and is rotatable relative to the mounting housing 10, and the position of the rotor 50 corresponds to the position of the stator 40.

[0064] One end of the snap fastener 60 engages with the rotor 50, and the other end of the snap fastener 60 extends into the arc-shaped suture hole 22 and can interfere with the arc-shaped suture needle 30.

[0065] When energized, at least one of the stator 40 and the rotor 50 can generate a magnetic field, causing an interaction force between the stator 40 and the rotor 50, thereby causing the rotor 50 to rotate relative to the mounting housing 10 and drive the snap-fit ​​member 60.

[0066] In addition, the electrically driven treatment device has a channel that matches the endoscope 100, and the axis of the channel, the rotation axis of the rotor 50, and the rotation axis of the arc-shaped suture needle 30 are parallel.

[0067] The electrically driven treatment device provided in this application comprises a stator 40 and a rotor 50 forming a motor or similar structure to drive the movement of the clamping member 60. Specifically, the clamping member 60 electrically drives the arc-shaped suture needle 30 to suture human tissue. On one hand, controlling the motor's speed, angle, and force provides precise power output, enabling accurate control of the arc-shaped suture needle 30 and improving the accuracy and safety of the surgery. On the other hand, because the motor has stable and powerful power output and precise torque control, it avoids the problems of insufficient mechanical transmission torsional / rotational force and susceptibility to malfunction that occur when the clamping member 60 is driven by a fully manual drive structure (which consists of multiple cooperating components).

[0068] The following describes several embodiments of this application with reference to specific examples.

[0069] Example 1

[0070] like Figures 1 to 6 As shown, the electrically driven treatment device provided in this application includes: a mounting housing 10, a suture seat 20, an arc-shaped suture needle 30, a stator 40, a rotor 50, and a snap-fit ​​component 60.

[0071] When energized, at least one of the stator 40 and the rotor 50 can generate a magnetic field, causing an interaction force between the stator 40 and the rotor 50, thereby causing the rotor 50 to rotate relative to the mounting housing 10 and drive the snap-fit ​​member 60.

[0072] Specifically, the rotor 50 includes a rotating body 51 and a plurality of first magnetic elements 52. Specifically, the axis of the channel and the axis of rotation of the rotating body 51 are parallel to the axis of rotation of the arc-shaped suture needle 30.

[0073] The rotating body 51 is disposed inside the mounting housing 10 and is capable of rotating relative to the mounting housing 10.

[0074] Multiple first magnetic elements 52 are disposed on the rotating body 51 and are arranged sequentially along the circumference of the rotating body 51.

[0075] The stator 40 includes a first conductor coil 41, which is located on one side of the rotating body 51, and the position of the first conductor coil 41 corresponds to the position of the first magnetic element 52.

[0076] The rotating body 51, multiple first magnetic components 52, and first conductor coil 41 constitute a drive device similar to a linear motor. The rotating body 51 and multiple first magnetic components 52 form the primary stage, and the first conductor coil 41 is the secondary stage. On the one hand, the structure of the drive device is relatively simple, mainly composed of a stator 40 and a mover, without a complex transmission mechanism, making the drive device more compact and facilitating the miniaturization and lightweight design of electrically driven therapeutic devices. On the other hand, the drive device has fewer intermediate transmission components, reducing mechanical wear points, thereby lowering equipment maintenance costs and downtime, and improving equipment reliability and service life.

[0077] like Figure 5 and Figure 6 As shown, in one embodiment of this application, a mounting position 11 is provided on the inner wall of the mounting shell 10. The mounting position 11 can be a mounting position 11 or a winding protrusion, and the first conductor coil 41 is disposed on the mounting position 11.

[0078] The mounting position 11 is designed so that the first coil 41 overlaps at least partially with the mounting housing 10, which can effectively utilize space, reduce the space occupied by the first coil 41, make the product more compact, and meet the design requirements of miniaturization and lightweighting of equipment.

[0079] like Figures 1 to 6 As shown, the mounting housing 10 includes an outer shell 12 and a base frame 13. The outer shell 12 is connected to the stitching seat 20.

[0080] The base frame 13 is disposed inside the housing 12 and is detachably connected to the housing 12, and the first conductor coil 41 is disposed on the base frame 13.

[0081] With the above structure, the first conductor coil 41 can be assembled onto the base frame 13 first, and then the base frame 13 can be assembled with the outer shell 12. Conversely, the base frame 13 and the outer shell 12 can be disassembled first, and then the first conductor coil 41 can be disassembled from the base frame 13. This facilitates the assembly and disassembly of the first conductor coil 41 and the mounting shell 10, and improves the assembly efficiency and maintenance efficiency of the product.

[0082] like Figures 1 to 6 As shown, in one embodiment of this application, the electrically driven treatment device further includes a sleeve 90.

[0083] The cannula 90 is located at the other end of the mounting housing 10 and extends into the mounting housing 10. The outlet of the cannula 90 is located inside the mounting housing 10 and is positioned towards the suture groove 21. The cannula 90 is configured to mate with the endoscope 100. Specifically, the axis of the cannula 90 channel, the axis of rotation of the rotating body 51, and the axis of rotation of the arc-shaped suture needle 30 are parallel.

[0084] The rotating body 51 is disposed on the outer surface of the sleeve 90 and is capable of rotating relative to the sleeve 90 in the circumferential direction of the sleeve 90.

[0085] The sleeve 90 provides a mounting position 11 for the rotating body 51, so that the rotating body 51 is located in the internal space of the mounting shell 10. This makes reasonable use of the internal space of the mounting shell 10, making the product more compact and meeting the design requirements of miniaturization and lightweighting of equipment.

[0086] In one embodiment of this application, the sleeve 90 includes a first pipe segment and a second pipe segment.

[0087] The diameter of the second pipe section is smaller than that of the first pipe section, and the second pipe section is located near the suture seat 20.

[0088] An annular step is formed at the intersection of the first pipe section and the second pipe section, and the rotating body 51 is set on the second pipe section.

[0089] The above structure allows the rotating body 51 to partially overlap with the first pipe section, reducing the space occupied by the rotating body 51, making the product more compact, and meeting the design requirements of equipment miniaturization and lightweighting.

[0090] Example 2

[0091] like Figures 7 to 10 As shown, the electrically driven treatment device provided in this application includes: a mounting housing 10, a suture seat 20, an arc-shaped suture needle 30, a stator 40, a rotor 50, and a snap-fit ​​component 60.

[0092] When energized, at least one of the stator 40 and the rotor 50 can generate a magnetic field, causing an interaction force between the stator 40 and the rotor 50, thereby causing the rotor 50 to rotate relative to the mounting housing 10 and drive the snap-fit ​​member 60.

[0093] Specifically, the stator 40 includes a fixed coil 42 and a plurality of second conductor coils 43.

[0094] Multiple second conductor coils 43 are fixed on the outer surface of the fixing ring 42.

[0095] The rotor 50 includes a rotating ring 53 and a plurality of second magnetic elements 54.

[0096] The rotating ring 53 is arranged around the fixed ring 42. Specifically, the axis of the channel and the axis of rotation of the rotating ring 53 are parallel to the axis of rotation of the arc-shaped suture needle 30.

[0097] Multiple second magnetic components 54 are fixed on the inner surface of the rotating ring 53 and arranged sequentially along the circumference of the rotating ring 53. The second magnetic components 54 are arranged corresponding to the second conductor coil 43, and the snap-fit ​​component 60 is connected to the rotating ring 53.

[0098] The stator 40 and rotor 50 constitute a drive device similar to a brushless hollow motor. On the one hand, the structure of the drive device is relatively simple, mainly composed of the stator 40 and the rotor, without a complex transmission mechanism, making the drive device more compact and facilitating the miniaturization and lightweight design of the electric drive therapy device. On the other hand, the drive device has fewer intermediate transmission components, and the motor itself directly acts as the rotating body, directly interfering with the locking component 60.

[0099] like Figures 7 to 10 As shown, in one embodiment of this application, the electrically driven treatment device further includes a sleeve 90.

[0100] The cannula 90 is located at the other end of the mounting housing 10 and extends into the mounting housing 10. The outlet of the cannula 90 is located inside the mounting housing 10 and is positioned toward the suture groove 21. The cannula 90 is configured to cooperate with the endoscope 100. The axis of the cannula 90 channel, the axis of rotation of the rotating ring 53, and the axis of rotation of the arc-shaped suture needle 30 are parallel.

[0101] The retaining ring 42 is fixed to the outer surface of the sleeve 90.

[0102] The sleeve 90 provides a mounting position 11 for the fixing ring 42, so that the fixing ring 42 is located in the internal space of the mounting shell 10. This makes reasonable use of the internal space of the mounting shell 10, making the product more compact and meeting the design requirements of miniaturization and lightweighting of equipment.

[0103] In one embodiment of this application, the sleeve 90 includes a first tube segment and a second tube segment, the diameter of the second tube segment being smaller than the diameter of the first tube segment, and the second tube segment being disposed adjacent to the suture seat 20.

[0104] An annular step is formed at the intersection of the first pipe section and the second pipe section, and the fixing ring 42 is set on the second pipe section.

[0105] The above structure allows the fixing ring 42 to partially overlap with the first pipe section, reducing the space occupied by the fixing ring 42, making the product more compact, and meeting the design requirements of equipment miniaturization and lightweighting.

[0106] Example 3

[0107] like Figures 11 to 16As shown, the electrically driven treatment device provided in this application includes: a mounting housing 10, a suture seat 20, an arc-shaped suture needle 30, a rotating body 71, a second transmission structure, a drive motor 73, and a snap-fit ​​component 60.

[0108] The rotating body 71 is rotatably mounted inside the mounting housing 10, and the rotating body 71 is provided with a first transmission structure arranged along its circumference.

[0109] The second transmission structure is movably connected to the first transmission structure, and the second transmission structure is configured to apply a force to the first transmission structure to cause the rotating body 71 to rotate relative to the mounting housing 10.

[0110] The drive motor 73 has its shaft fixedly connected to the second transmission structure. The drive motor 73 includes a stator 40 and a rotor 50. The rotor 50 is a hollow winding 55, and the stator 40 is a permanent magnet. The axis of the channel and the rotation axis of the rotor 50 (the rotation axis of the rotating body 71) are parallel to the rotation axis of the arc-shaped suture needle 30.

[0111] like Figure 13 As shown, the hollow winding 55 is made of wire wound into a hollow column shape, and the shaft is connected to the hollow winding 55.

[0112] A permanent magnet is arranged around the rotor 50.

[0113] The drive motor 73 is a coreless motor. On the one hand, the structure of the coreless motor is relatively simple and compact. The absence of an iron core greatly reduces its size and weight, making the drive motor 73 more compact and facilitating the miniaturization and lightweight design of the electric drive treatment device. On the other hand, the coreless motor has good linearity in its mechanical and adjustment characteristics, enabling precise speed and position control, and precise control of the arc-shaped suture needle 30, thereby improving the accuracy and safety of the surgery.

[0114] like Figures 11 to 16 As shown, in one embodiment of this application, the first transmission structure is a transmission tooth disposed on the rotating body 71, and the second transmission structure is a gear 72, which meshes with the transmission tooth. In a specific embodiment of this application, the rotating body 71 is an arc-shaped rack, or the rotating body 71 is a ring gear 72.

[0115] The transmission between the rotating body 71 and the second transmission structure is a gear 72 transmission. On the one hand, the gear 72 transmission has low energy loss and high transmission efficiency during power transmission, which can more effectively drive the snap-fit ​​component 60 and the arc-shaped suture needle 30. On the other hand, the gear 72 transmission has a more compact structure and occupies less space, making the product more compact and facilitating the miniaturization and lightweight design of the electric drive treatment device.

[0116] In one embodiment of this application, the first transmission structure is a connecting groove, which is disposed on the rotating body 71.

[0117] The second transmission structure includes: a transmission wheel and a transmission belt.

[0118] The transmission wheel is connected to the shaft of the drive motor 73.

[0119] One end of the transmission belt is fitted onto the transmission wheel, and the other end of the transmission belt is fitted into the connecting groove.

[0120] The transmission between the rotating body 71 and the second transmission structure is a belt drive, which can enable the rotating body 71 and the second transmission structure to work normally within a large center distance range. The distance between the rotating body 71 and the second transmission structure can be flexibly adjusted according to the actual equipment layout and space requirements, so as to make reasonable use of the internal space of the mounting shell 10.

[0121] In one embodiment of this application, the mounting housing 10 includes: a housing 12 and a base frame 13.

[0122] The outer casing 12 is connected to the sewing seat 20.

[0123] The base frame 13 is disposed inside the housing 12 and is detachably connected to the housing 12, and the drive motor 73 is fixed on the base frame 13. Specifically, the base frame 13 is provided with an installation space 14, and the drive motor 73 is disposed on the installation space 14.

[0124] With the above structure, the drive motor 73 can be assembled onto the base frame 13 first, and then the base frame 13 can be assembled with the outer shell 12. Conversely, the base frame 13 and the outer shell 12 can be disassembled first, and then the drive motor 73 can be disassembled from the base frame 13. This facilitates the assembly and disassembly of the drive motor 73 and the mounting shell 10, and improves the assembly and maintenance efficiency of the product.

[0125] like Figure 15 As shown, in one embodiment of this application, the electrically driven treatment device further includes a limiting structure 80.

[0126] The limiting structure 80 is disposed inside the mounting housing 10 and located on the rotation path of the snap-fit ​​member 60, and the limiting structure 80 can interfere with the snap-fit ​​member 60.

[0127] The limiting structure 80 restricts the rotation angle of the rotating body 71 by adjusting the rotation angle of the snap-fit ​​60, thereby preventing mechanical damage caused by excessive rotation of the rotating body 71, extending the service life of the equipment, and reducing equipment maintenance costs.

[0128] like Figures 11 to 16 As shown, in one embodiment of this application, the electrically driven treatment device further includes a sleeve 90.

[0129] The cannula 90 is located at the other end of the mounting housing 10 and extends into the mounting housing 10. The outlet of the cannula 90 is located inside the mounting housing 10 and is positioned toward the suture groove 21. The cannula 90 is configured to mate with the endoscope 100.

[0130] The rotating body 71 is disposed on the outer surface of the sleeve 90 and is capable of rotating relative to the sleeve 90 in the circumferential direction of the sleeve 90.

[0131] The sleeve 90 provides a mounting position 11 for the rotating body 71, so that the rotating body 71 is located in the internal space of the mounting shell 10. This makes reasonable use of the internal space of the mounting shell 10, making the product more compact and meeting the design requirements of miniaturization and lightweighting of equipment.

[0132] In one embodiment of this application, the sleeve 90 includes a first tube segment and a second tube segment, the diameter of the second tube segment being smaller than the diameter of the first tube segment, and the second tube segment being disposed adjacent to the suture seat 20.

[0133] An annular step is formed at the intersection of the first pipe segment and the second pipe segment, and the rotating body 71 and the fixed ring 42 or the rotating body 71 are set on the second pipe segment.

[0134] The above structure allows the rotating body 71 to partially overlap with the first pipe section, reducing the space occupied by the rotating body 71, making the product more compact, and meeting the design requirements of equipment miniaturization and lightweighting.

[0135] Example 4

[0136] like Figure 17 and Figure 18 As shown, the scheme of Embodiment 4 is largely the same as that of Embodiment 3, with the main difference being that the stator 40 includes a metal support 44 and a first winding 45.

[0137] The metal support 44 has a through hole.

[0138] The first winding 45 is coiled on the metal support 44.

[0139] The rotor 50 is a permanent magnet component, which is located inside the through hole.

[0140] The drive motor 73 is a brushless motor. On the one hand, since it lacks the two easily worn components of brushes and commutator, it avoids the problem of needing to replace brushes periodically due to wear, thus extending the service life of the drive motor 73. On the other hand, it can quickly respond to changes in control signals, achieving higher speeds and accelerations, thereby enabling more flexible and precise driving of the snap-fit ​​component 60 and the arc-shaped sewing needle 30.

[0141] Example 5

[0142] The scheme of Embodiment 5 is largely the same as that of Embodiment 3, with the main difference being that the stator includes an iron core and a second winding, the second winding is wound on the iron core, and the second winding is configured to generate a rotating magnetic field after being energized.

[0143] The rotor includes a stack of metal sheets and a third winding or conductive component disposed on the stack of metal sheets. In the rotating magnetic field, the third winding or conductive component generates an induced current, which interacts with the magnetic field generated by the stator to realize the rotation of the rotor.

[0144] The drive motor is a magnetless motor. Magnetless motors utilize contactless inductive power transmission, making them particularly efficient and durable at high speeds. This design reduces wear, extends motor lifespan, and minimizes maintenance requirements.

[0145] It should be noted that the electrically driven treatment device preferably features a three-dimensional frame structure design. Specifically, the axis of the channel through which the mounting shell 10 or cannula 90 is connected to the endoscope 100, the axis of the rotating body, and the axis of rotation of the arc-shaped suture needle 30 are parallel to form a three-dimensional frame structure. To match the structural characteristics of the flexible endoscope 100 and conform to its operating habits, this three-dimensional frame structure design allows for more efficient arrangement of components, without complex structures or large outer diameter dimensions, thus improving the usability and reliability of the device.

[0146] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.

In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
