This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0031] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0032] The serial numbers assigned to components herein, such as "first" and "second," are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" in this application, unless otherwise specified, include direct, indirect, and contact connections (couplings).

[0033] In response to the current problem of inconvenient tightening of silk threads, the present application provides a manual tightening device for soft tissue, which applies a one-way locking force to the movable part of the one-way anti-retraction mechanism through an elastic part, so that the one-way anti-retraction mechanism maintains a one-way locking silk thread. When tightening is required, the silk thread can be directly pulled out to achieve tightening.

[0034] In one embodiment, please refer to Figures 1 to 10 The manual soft tissue tightening device includes a thread 1, a base 2, and an elastic member 3. The thread 1 is used to tighten the soft tissue to achieve soft tissue removal. The base 2 is provided with a one-way stop mechanism 4, which is used to unidirectionally lock the thread 1, allowing at least one end of the thread 1 to move in the direction of tightening the soft tissue and preventing the thread 1 from loosening the tightened soft tissue. At least one end of the thread 1 is a pulling end 11, which is used for pulling operation to achieve the tightening of the soft tissue by the thread 1.

[0035] At least part of the one-way stop mechanism 4 is a movable portion 41 movably disposed on the base 2. The elastic member 3 is assembled on the base 2 and is used to apply elastic force to the movable portion 41, so that the movable portion 41 maintains a one-way locking force on the thread 1, thereby achieving the one-way locking of the thread 1 by the one-way stop mechanism 4.

[0036] The manual soft tissue tightening device uses a one-way stop mechanism 4 to unidirectionally lock the thread 1. The elastic force exerted by the elastic member 3 on the movable portion 41 of the one-way stop mechanism 4 enables the one-way stop mechanism 4 to maintain the lock on the thread 1. Once locked, the thread 1 can only be pulled further to tighten the soft tissue and cannot be moved in a direction to loosen the soft tissue. During the tightening operation, the thread 1 only needs to be pulled to achieve tightening, making the operation simple and convenient.

[0037] The thread 1 may be any feasible form in the medical field in the prior art, for example, an elastic thread or a flexible thread without elasticity.

[0038] Further, in order to facilitate the thread 1 to wrap around the soft tissue and tighten it, in one embodiment, please refer to Figures 4 to 7 , the movable portion 41 has a release position (see Figure 4 and Figure 5 ) and locked position (see Figure 7 ), elastic member 3 is used to move movable portion 41 toward and maintain the locked position. Base 2 is provided with a blocking structure 5, which is used to position movable portion 41 in the released position. Active portion 41 is used to lock thread 1 after the blocking effect of blocking structure 5 is released. Blocking structure 5 maintains movable portion 41 in the released position, facilitating manipulation of thread 1. Once thread 1 is entrained around soft tissue, the blocking effect of blocking structure 5 is released, allowing one-way stop mechanism 4 to unidirectionally lock thread 1.

[0039] In some other embodiments, in addition to using the blocking structure 5 to keep the movable part 41 in the released position, the movable part 41 can also be kept in the released position by the operator. For the convenience of operation, the movable part 41 can be provided with a handle for the operator to operate.

[0040] In one embodiment, please refer to Figure 1 、 Figure 6 and Figure 10In order to facilitate the unlocking of the blocking structure 5, the soft tissue manual tightening device comprises a cover 6, which comprises a releasing structure 61 that exerts force on the blocking structure 5 during the covering of the base 2 by the cover 6, thereby releasing the blocking effect of the blocking structure 5. In some other embodiments, in addition to the cover 6, the blocking structure 5 can also be released in other ways, for example, the blocking structure 5 is provided with an operating handle, and the operator directly operates the blocking structure 5 through the operating handle; for example, the blocking structure 5 is operated through another operating tool.

[0041] In an embodiment, please refer to Figure 6 After the cover 6 covers the base 2, the cover 6 is fixed with the base 2. Specifically, the cover 6 and the base 2 can be fixed together through interference fit, clamping and the like.

[0042] Specifically, in an embodiment, please refer to Figure 6 The blocking structure 5 is a disposable structure fixed with the base 2. By separating the blocking structure 5 from the base 2, the blocking effect of the blocking structure 5 is released. In an embodiment, in addition to the way of separating the blocking structure 5 from the base 2, the blocking structure 5 can also be deformed to release the blocking effect of the blocking structure 5. In an embodiment, please refer to Figure 6 The blocking structure 5 and the base 2 can be fixed through one-piece molding, welding, bonding, fastener connection or clamping.

[0043] Specifically, in an embodiment, please refer to Figure 5 and Figure 6 The blocking structure 5 is a blocking arm 50. The base 2 has an ejection channel 21 for the blocking structure 5 to be ejected, and the blocking arm 50 can be ejected from the ejection channel 21 under the action of gravity after being separated from the base 2.

[0044] In an embodiment, please refer to Figures 1 to 7 Since the blocking structure 5 is a disposable structure, before using the soft tissue manual tightening device, the cover 6 and the base 2 are in a separated state, and after the operator completes the installation of the silk thread 1 on the soft tissue and with the base 2, the cover 6 is covered on the base 2 to complete the assembly of the soft tissue manual tightening device. After the assembly is completed, the silk thread 1 is tightened by pulling the pulling end 11 of the silk thread 1. In some other embodiments, the cover 6 can also be pre-assembled with the base 2, and when the silk thread 1 needs to be locked, the cover 6 is pressed to release the blocking effect of the blocking structure 5.

[0045] In order to facilitate the separation of the blocking structure 5 from the base 2, in an embodiment, please refer to Figure 5 and Figure 6A weak structure 51 is provided at the connection between the blocking structure 5 and the base 2. When the blocking structure 5 is subjected to an external force that releases the blocking effect, the blocking structure 5 and the base 2 are disconnected and separated at the weak structure 51. Figure 5 、 Figure 6 and Figure 9 , the weak structure 51 is a thinning groove 510, and the notch of the thinning groove 510 faces the gland 6 or faces away from the gland 6. In one embodiment, please refer to Figure 5 、 Figure 6 and Figure 9 There are two thinning grooves 510, one of which faces the gland 6 and the other faces away from the gland 6. In this way, when the gland 6 is covered on the base 2, it is easier to separate the blocking structure 5 from the base 2. In some other embodiments, the number of thinning grooves can also be one or more than two. In some other embodiments, in addition to the thinning grooves 510, other structures, such as a plurality of holes in the weak structure 51, can also be opened to reduce the strength of the connection between the blocking structure 5 and the base 2. In some other embodiments, the weak structure 51 can also be made of a material that is easier to break than other parts.

[0046] It should be noted that the strength of the weak structure 51 of the present application is weaker than that of other parts of the blocking structure 5. Therefore, the weak structure 51 is weaker than other parts and is more easily broken. In some other embodiments, the connection between the blocking structure 5 and the base 2 may not have the weak structure 51, provided that the design requirements are met and the blocking structure 5 can be disconnected from the base 2.

[0047] Specifically, in one embodiment, please refer to Figure 6 and Figure 9 The release structure 61 includes a pressing member 610, which presses the blocking structure 5 to separate the blocking structure 5 from the base 2 or deform the blocking structure 5. Figure 6 and Figure 9 , the top pressure piece 610 is a top rod.

[0048] In one embodiment, please refer to Figure 6 Since one end of the blocking structure 5 supports the movable part 41 and the other end is connected to the base 2, in order to facilitate the separation of the blocking structure 5 from the base 2, the pressing member 610 acts on the suspended end of the blocking structure 5.

[0049] In one embodiment, the one-way locking mechanism 4 locks the wire 1 in a one-way manner as follows: the one-way locking mechanism 4 clamps the wire 1 so that the wire 1 can only be pulled in the tightening direction relative to the one-way locking mechanism 4 .

[0050] Specifically, in one embodiment, please refer to Figure 2 、Figure 4 、 Figure 5 and Figure 7 The one-way anti-retraction mechanism 4 includes a first anti-retraction rack 410 and a second anti-retraction rack 42. The first anti-retraction rack 410 is located on the movable portion 41, and the second anti-retraction rack 42 is located on the base 2. The meshing action of the teeth on the first anti-retraction rack 410 and the teeth on the second anti-retraction rack 42 can better clamp the wire 1 and prevent the wire 1 from retreating. In one embodiment, the teeth on the first anti-retraction rack 410 and the second anti-retraction rack 42 are anti-retraction teeth.

[0051] In one embodiment, please refer to Figure 7 Taking the anti-backward tooth 411 on the first anti-backward rack 410 as an example, the two tooth surfaces of the anti-backward tooth 411 are respectively the first tooth surface 4111 and the second tooth surface 4112. The first tooth surface 4111 and the second tooth surface 4112 are both planes. The direction in which the wire 1 is pulled is the first direction, wherein the orientation of the first tooth surface 4111 is consistent with the first direction, that is, the first direction is the normal direction of the first tooth surface 4111. Please refer to Figure 7 When the movable portion 41 is in the released position, the second tooth surface 4112 gradually approaches the wire 1 in the first direction from the tooth root to the tooth top. In some other embodiments, in addition to making the first direction the normal direction of the first tooth surface 4111, the first tooth surface 4111 and the second tooth surface 4112 can also be inclined surfaces, and the first tooth surface 4111 can also gradually approach the wire 1 in the first direction from the tooth root to the tooth top.

[0052] In some other embodiments, the one-way anti-recoil mechanism 4 may employ any other feasible structural form besides a rack. For example, the one-way anti-recoil mechanism 4 may employ a rebound pawl. The number of rebound pawls can be set as needed. There may be two rebound pawls, in which case the two rebound pawls are located on opposite sides of the wire 1. The number of rebound pawls may also be one or more than three. It should be noted that the rebound pawl is a movable portion 41, which can be movable relative to the base 2 after deformation. For another example, in addition to the rebound pawl, the one-way anti-recoil mechanism 4 may also employ a rigid pawl, which can be movably mounted on the base 2.

[0053] Regarding the installation method of the movable part 41, in one embodiment, please refer to Figures 4 to 8 In order to facilitate the installation of the movable part 41, the movable part 41 is hinged on the base 2. Specifically, in one embodiment, please refer to Figures 4 to 8 The manual soft tissue tightening device includes a hinge shaft 7, and the movable part 41 is hinged to the base 2 via the hinge shaft 7. In one embodiment, please refer to Figure 4 and Figure 5The movable portion 41 is integrally formed with the hinge shaft 7. In some other embodiments, the hinge shaft may be movably connected to the movable portion 41, for example, the movable portion 41 may have a hinge shaft hole through which the hinge shaft passes. In some other embodiments, in addition to being hinged, the movable portion 41 may also adopt any other feasible connection method, for example, the movable portion 41 may be connected to the base 2 via a flexible connection, or the movable portion 41 may be slidably mounted on the base 2, and the movable portion 41 may move linearly from a released position to a locked position.

[0054] Further, in one embodiment, please refer to Figure 6 The base 2 includes a base body 22 and a bottom cover 23. The bottom cover 23 is fixed to the base body 22, and the movable portion 41 is sandwiched between the bottom cover 23 and the base body 22. This facilitates the installation of the movable portion 41. In one embodiment, one end of the hinge shaft 7 is inserted into the base body 22, and the other end is inserted into the bottom cover 23. In some other embodiments, the base 2 is an integrally molded structure, in which case the movable portion 41 can be directly installed on the base 2.

[0055] Specifically, in one embodiment, please refer to Figure 2 and Figure 9 , the seat body 22 has a positioning hole 221, please refer to Figure 8 The bottom cover 23 includes a bottom cover column 231 inserted into the positioning hole 221. The bottom cover column 231 cooperates with the positioning hole 221 to facilitate the installation of the bottom cover. In one embodiment, please refer to Figure 2 、 Figure 8 and Figure 9 The bottom cover column 231 and the positioning hole 221 have an interference fit to secure the bottom cover 23 to the base 22. In some other embodiments, the bottom cover can also be secured to the base by having an interference fit between the circumference of the bottom cover and the base. In some other embodiments, the bottom cover and the base can also be secured by screws, bonding, welding, or clamping, among other feasible methods.

[0056] In one embodiment, please refer to Figure 10 The gland 6 includes a gland column 62. There are at least two gland columns 62. One of the gland columns 62 and the bottom cover column 231 share a positioning hole 221. In one embodiment, please refer to Figure 10 At least one gland column 62 is a first gland column 621, and at least one gland column 62 is a second gland column 622. After the gland 6 is installed on the base 2, the wire 1 passes between the first gland column 621 and the second gland column 622. The first gland column 621 and the second gland column 622 are located at the position where the wire 1 is led out of the base 2. A wire groove 63 is provided between the first gland column 621 and the second gland column 622. The notch of the wire groove 63 faces the base 2, and the wire 1 passes through the wire groove 63. After the gland 6 is installed on the base 2, the notch of the wire groove 63 is blocked by the base 2.

[0057] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the base 2 has a wire hole 24 for holding the position of the holding end 12 of the wire 1. Specifically, in one embodiment, the holding end 12 of the wire 1 is tied and clamped in or out of the wire hole 24 so that the position of the holding end 12 is kept unchanged. In some other embodiments, the holding end 12 of the wire 1 can also be fixed on the base 2 by adhesion, hooking or fasteners.

[0060] In order to facilitate the installation of the spring, in one embodiment, as shown in Figures 4 to 8 , the movable part 41 has a spring positioning groove 412, one end of the spring being assembled into the spring positioning groove 412.

[0061] In some other embodiments, in addition to the spring, the elastic member can also use an elastic band, which is in an elongated state and can pull the movable part to move.

[0062] In one embodiment, as shown in Figures 1 to 10 , the process of using the soft tissue manual tightening device is as follows:

[0063] The operator installs the silk thread 1 and the base 2 and puts them on the soft tissue. Under the guidance of the gland column 62, the gland 6 is covered on the base 2. The top pressing piece 610 on the gland 6 disconnects the blocking structure 5 from the base 2 by pressing the blocking structure 5. The blocking structure 5 is discharged through the discharge channel 21. The gland 6 is interference fit with the base 2 through the gland column 62 to complete the assembly of the manual tightening device for soft tissue. After the assembly is completed, the silk thread 1 is tightened to the soft tissue by pulling the pulling end 11 of the silk thread 1. Under the action of the one-way stop mechanism 4, the silk thread 1 keeps tightening the soft tissue. After a period of time, when tightening is needed, the pulling end 11 of the silk thread 1 is directly operated to operate.
