In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and 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 can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0032] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct connection, indirect connection and contact connection (coupling), etc.

[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 stop mechanism through an elastic member, so that the one-way stop mechanism maintains the 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 tightening device for soft tissue comprises a thread 1, a base 2 and an elastic member 3. The thread 1 is used to tighten the soft tissue to achieve the removal of the soft tissue. A one-way stop mechanism 4 is provided on the base 2. The one-way stop mechanism 4 is used to lock the thread 1 in one direction to allow at least one end of the thread 1 to move in the direction of tightening the soft tissue and prevent the thread 1 from loosening the tightened soft tissue. At least one end of the thread 1 is a pulling end 11, and the pulling end 11 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 part 41 movably arranged on the base 2. The elastic member 3 is assembled on the base 2, and the elastic member 3 is used to apply elastic force to the movable part 41, so that the movable part 41 maintains a one-way locking force on the wire 1, thereby realizing that the one-way stop mechanism 4 maintains a one-way locking of the wire 1.

[0036] The manual tightening device for soft tissue adopts a one-way stop mechanism 4 to lock the thread 1 in one direction. The elastic force applied by the elastic member 3 to the movable part 41 of the one-way stop mechanism 4 can make the one-way stop mechanism 4 keep locking the thread 1. After the thread 1 is locked, it can only be further pulled to tighten the soft tissue and cannot move in the direction of loosening the soft tissue. During the tightening operation, only the thread 1 needs to be pulled to achieve tightening, and the operation is 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 part 41 has a loose position (see Figure 4 and Figure 5 ) and locked position (see Figure 7 ), the elastic member 3 is used to move the movable part 41 to the locking position and maintain it. The base 2 is provided with a blocking structure 5, which is used to make the movable part 41 in a loosened position. The movable part 41 is used to lock the thread 1 after the blocking effect of the blocking structure 5 is released. The blocking structure 5 keeps the movable part 41 in the loosened position, which facilitates the operation of the thread 1. After the thread 1 is wrapped around the soft tissue, the blocking effect of the blocking structure 5 is released to make the one-way stop mechanism 4 lock the thread 1 in one direction.

[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 Fig.10In order to facilitate unlocking of the blocking structure 5, the manual soft tissue tightening device includes a pressure cover 6, and the pressure cover 6 includes a release structure 61. The release structure 61 applies force to the blocking structure 5 during the process of the pressure cover 6 covering the base 2 to release the blocking effect of the blocking structure 5. In some other embodiments, in addition to using the pressure cover 6 to release the blocking structure 5, the blocking structure 5 can also be released in other ways, for example, the blocking structure 5 has an operating handle, and the operator directly operates the blocking structure 5 through the operating handle; for another example, the blocking structure 5 is operated by another operating tool.

[0041] In one embodiment, please refer to Figure 6 After the pressure cover 6 is covered on the base 2, the pressure cover 6 is fixed together with the base 2. Specifically, the pressure cover 6 and the base 2 can be fixed together by interference fit, clamping, etc.

[0042] Specifically, in one embodiment, please refer to Figure 6 The blocking structure 5 is a disposable structure fixed to the base 2. By separating the blocking structure 5 from the base 2, the blocking effect of the blocking structure 5 is released. In one embodiment, in addition to 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 one embodiment, please refer to Figure 6 The blocking structure 5 and the base 2 can be fixed by integral molding, welding, bonding, fastener connection or clamping.

[0043] Specifically, in one embodiment, please refer to Figure 5 and Figure 6 The blocking structure 5 is a blocking arm 50. The base 2 has a discharge channel 21 for discharging the blocking structure 5. After the blocking arm 50 is separated from the base 2, the blocking arm 50 can be discharged from the discharge channel 21 under the action of gravity.

[0044] In one embodiment, please refer to Figures 1 to 7 Since the blocking structure 5 is a disposable structure, before using the manual tightening device for soft tissue, the gland 6 and the base 2 are separated. After the operator puts the silk thread 1 on the soft tissue and installs it with the base 2, the gland 6 is covered on the base 2 to complete the assembly of the manual tightening device for soft tissue. 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 gland 6 can also be pre-assembled with the base 2. When the silk thread 1 needs to be locked, the gland 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 one 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 Fig. 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 Fig. 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 made 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 less than the strength of other parts of the blocking structure 5. The weak structure 51 is weaker than other parts and is more likely to be broken. In some other embodiments, under the premise that the blocking structure 5 can be disconnected from the base 2 as required by the design, there may be no weak structure 51 at the connection between the blocking structure 5 and the base 2.

[0047] Specifically, in one embodiment, please refer to Figure 6 and Fig. 9 The release structure 61 includes a pressing member 610, and the pressing member 610 presses the blocking structure 5 to separate the blocking structure 5 from the base 2 or to deform the blocking structure 5. Specifically, in one embodiment, please refer to Figure 6 and Fig. 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 backstop mechanism 4 includes a first backstop rack 410 and a second backstop rack 42. The first backstop rack 410 is on the movable part 41, and the second backstop rack 42 is on the base 2. Through the meshing action of the teeth on the first backstop rack 410 and the teeth on the second backstop rack 42, the wire 1 can be better clamped and prevented from retreating. In one embodiment, the teeth on the first backstop rack 410 and the second backstop rack 42 are backstop teeth.

[0051] In one embodiment, please refer to Figure 7 , taking the stop tooth 411 on the first stop rack 410 as an example, the two tooth surfaces of the stop 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 in the first direction, the first tooth surface 4111 can also gradually approach the wire 1 in the direction from the tooth root to the tooth top.

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