Figure 12 and Figure 13 Schematic diagram of the soft tissue clamp provided in this embodiment from two perspectives.
[0065] The soft tissue graft fixator provided in this embodiment can be used to clamp and support soft tissue to facilitate soft tissue arrangement, such as tendon arrangement.
[0066] See also Figures 1-11 As shown, the soft tissue graft fixator includes a main body 110 , a secondary body 120 , a joint 130 and a fastener 140 .
[0067] At least one connector 130 is connected to the main body 110 , and the connector 130 is configured to be detachably connected to the soft tissue clamp 200 or the hook column 300 ; for example, one, two or other number of connectors 130 are connected to the main body 110 .
[0068] The main body 110 has a main clamping surface 111 , and the auxiliary body 120 has an auxiliary clamping surface 121 .
[0069] The fastener 140 passes through the main member 110 and is threadedly connected to the auxiliary member 120; the fastener 140 is configured to be rotatable to drive the auxiliary member 120 toward or away from the main member 110, thereby causing the auxiliary clamping surface 121 to approach or move away from the main clamping surface 111, so as to clamp the soft tissue graft holder on an instrument box or other base, or to remove the soft tissue graft holder from the instrument box or other base.
[0070] The soft tissue graft fixator described in this embodiment is capable of rotating, via a fastener 140, to drive the secondary member 120 toward or away from the main member 110, thereby moving the secondary clamping surface 121 toward or away from the main clamping surface 111. Specifically, the soft tissue graft fixator is clamped to an instrument box or other base via the main clamping surface 111 of the main member 110 and the secondary clamping surface 121 of the secondary member 120. The soft tissue graft fixator is detachably connected to the soft tissue clamp 200 or hook post 300 via a connector 130 to facilitate tendon and other soft tissue manipulation. This soft tissue graft fixator meets the needs of surgical procedures, is compact, and has a relatively simple structure, effectively reducing manufacturing costs and sales price. It can be stored alongside common instruments for cleaning and sterilization, effectively reducing sterilization costs.
[0071] See also Figures 1-8As shown, in an optional solution of this embodiment, the main member 110 includes a connected main base 113 and a main jaw 112; a joint 130 is connected to the side of the main base 113 away from the main jaw 112; the main jaw 112 is provided with a through hole for the fastener 140 to pass through, and the main clamping surface 111 is located on the side of the main jaw 112 closer to the auxiliary clamping surface 121. Optionally, the main jaw 112 and the fastener 140 have an interference fit to facilitate rotation of the fastener 140. In this embodiment, the auxiliary member 120 and the joint 130 are disposed on opposite sides of the main member 110.
[0072] See also Figure 1 and Figure 5 As shown, in an optional solution of this embodiment, an elastic member 150 is connected between the main jaw portion 112 and the auxiliary member 120. The elastic member 150 has elastic deformation that causes the auxiliary jaw surface 121 to move away from the main jaw surface 111. Optionally, the elastic member 150 is an elastic material such as a spring, silicone, or rubber. The elastic member 150 can drive the auxiliary jaw surface 121 away from the main jaw surface 111 when the soft tissue graft holder is removed from the instrument box or other base. In other words, the elastic member 150 can drive the auxiliary jaw surface 121 away from the main jaw portion 112, thereby facilitating the removal of the soft tissue graft holder.
[0073] Optionally, the main clamp portion 112 is provided with a main elastic member groove 1122 on the main clamp surface 111, and the auxiliary clamp portion 120 is provided with an auxiliary elastic member groove 122 on the auxiliary clamp surface 121. At least a portion of the elastic member 150 is accommodated in the main elastic member groove 1122, and at least another portion of the elastic member 150 is accommodated in the auxiliary elastic member groove 122. The main elastic member groove 1122 and the auxiliary elastic member groove 122 facilitate accommodating the elastic member 150. Optionally, the elastic member 150 is sheathed over the fastener 140, which not only prevents the elastic member 150 from falling but also facilitates the elastic member 150 to drive the auxiliary clamp surface 121 away from the main clamp surface 111.
[0074] See also Figure 7 As shown, in an optional solution of this embodiment, a rotation-stopping structure 160 is provided between the main clamp portion 112 and the auxiliary part 120; the rotation-stopping structure 160 is used to avoid or reduce the rotation of the auxiliary part 120 that may be caused by the rotation of the fastener 140, thereby effectively ensuring the clamping ability between the main clamping surface 111 of the main part 110 and the auxiliary clamping surface 121 of the auxiliary part 120.

[0079] In an optional solution of this embodiment, the shape of the anti-rotation protrusion 161 includes one or more of a cylinder, a rectangular column or an elliptical column. The anti-rotation protrusion 161 can also adopt other shapes.
[0080] Optionally, when the shape of the anti-rotation protrusion 161 includes a cylinder, the cross-section of the anti-rotation groove 162 is non-circular, for example, the cross-section of the anti-rotation groove 162 is an oblong.

[0089] The tendon braiding system base described in this embodiment can be rotated by the fastener 140 of the soft tissue graft fixator 100 to drive the auxiliary member 120 toward or away from the main member 110, thereby moving the auxiliary clamping surface 121 toward or away from the main clamping surface 111. In other words, the soft tissue graft fixator is clamped to the instrument box 400 by the main clamping surface 111 of the main member 110 and the auxiliary clamping surface 121 of the auxiliary member 120, and is disassembled and connected to the soft tissue clamp 200 or hook post 300 via the joint 130 to achieve the arrangement of soft tissue such as tendons.
