[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0032] Reference Figures 1 to 6 As shown, the embodiment of the present invention provides a wearable wristband device that can quickly lock and unlock itself, including:

[0033] The wristband assembly 100 includes an inner wristband 110 and a wristband strap 120. The inner wristband 110 is an arc-shaped structure, including two inner wristband ends 111 and an inner wristband body 112 disposed between the two inner wristband ends 111. The inner wristband body 112 of the inner wristband 110 is provided with two through holes 113. The two ends of the wristband strap 120 pass through the through holes 113 and are connected to each other. The length of the wristband strap 120 is adjustable. The wristband strap 120 of the wristband assembly 100 can be worn on the wrist.

[0034] The wristband frame 200 is provided outside the wristband assembly 100 and is used to dock surgical instruments; mounting grooves 210 are symmetrically provided on both sides of the wristband frame 200, and a first groove 220 extending downward is provided on the top of the wristband frame 200;

[0035] Two connecting components 300, the connecting component 300 is used to connect the inner bracelet end 111 and the bracelet frame 200; the connecting component 300 includes a rotating wheel 310, a connecting member 320 and an unlocking member 330; the rotating wheel 310 is rotatably connected to the mounting groove 210 through a pin shaft, and the rotating wheel 310 includes a plurality of tooth claws 311 arranged at intervals along the circumference, and a clamping groove 312 is provided between two adjacent tooth claws 311; the connecting member 320 is connected to the end of the inner bracelet 110; the connecting member 320 is inserted into the first groove 220 and cooperates with the clamping groove 312; the unlocking member 330 is installed in the mounting groove 210 and is located on one side of the rotating wheel 310; the unlocking member 330 moves toward the rotating wheel 310 to limit the counterclockwise rotation of the rotating wheel 310; the unlocking member 330 moves away from the rotating wheel 310 to disengage the two.

[0036] When the connecting member 320 is placed in the first groove 220 of the bracelet frame 200, the connecting member 320 can drive the rotating wheel 310 to rotate clockwise (at this time, the tooth claw 311 on the rotating wheel 310 close to the unlocking member 330 will push the unlocking member 330 open) until the connecting member 320 is located in the clamping groove 312. At this time, the unlocking member 330 moves toward the rotating wheel 310 and cooperates with the tooth claw 311 to limit the counterclockwise rotation of the rotating wheel 310, thereby realizing the self-locking of the inner bracelet 110; the unlocking member 330 moves to the side away from the rotating wheel 310, so that the unlocking member 330 and the rotating wheel 310 are disengaged, and the connecting member 320 moves upward to drive the rotating wheel 310 to rotate counterclockwise, thereby realizing the disassembly of the inner bracelet 110 and the fixed bracelet part.

[0037] Specifically, the unlocking member 330, the rotating wheel 310 and the connecting member 320 in this embodiment can cooperate to realize the self-locking after the inner bracelet 110 and the bracelet frame 200 are connected and fixed, and the unlocking realizes the rapid disassembly of the inner bracelet 110 and the bracelet frame 200. It can be seen that the inner bracelet 110 and the bracelet frame 200 in this embodiment can be quickly installed and disassembled, and are more convenient to use. In addition, this embodiment is provided with a bracelet frame 200 and a bracelet assembly 100 connected to the bracelet frame 200. The bracelet assembly 100 can be used to be worn on the wrist, and the bracelet frame 200 is used to dock with surgical instruments, so that the wrist or arm does not need to directly support the surgical instrument, thereby avoiding damage to the doctor's wrist and arm. Secondly, the bracelet band 120 in this embodiment can be worn on the wrist, and the length of the bracelet band 120 is adjustable to match the wrist size of different doctors and improve comfort.

[0038] Furthermore, the connecting assembly 300 further includes an end cap 340; the end cap 340 is connected to the bracelet frame 200 via a fixing screw 350, and the end cap 340 covers the outside of the mounting groove 210. Specifically, the end cap 340 provided in this embodiment further limits the position of the rotating wheel 310 and the unlocking member 330 installed in the mounting groove 210.

[0039] Furthermore, a stopper 211 is provided at the top of the mounting groove 210, and a through groove 230 is provided between the bracelet frame 200 and the stopper 211, the through groove 230 being in communication with the mounting groove 210; the unlocking member 330 is a spring; the bottom end of the spring is connected to the bracelet frame 200, and the other end of the spring passes through the mounting groove 210 and the through groove 230 to extend above the bracelet frame 200 (this end of the spring is referred to as the inclined rod end 331). The spring elastically deforms and moves back and forth in the through groove 230, and the spring abuts against the stopper 211. Specifically, this embodiment has a simple structure and is quick and easy to operate.

[0040] Furthermore, the portion of the spring extending to the upper portion of the bracelet frame 200 is tilted (ie, the tilted rod end 331). Specifically, this embodiment can more conveniently manually press the spring to unlock.

[0041] Furthermore, a flange 212 is provided on one side of the mounting groove 210 where the unlocking member 330 is provided; the bottom end of the spring is bent to form a second groove 332, which cooperates with the flange 212. Specifically, in this embodiment, the spring and the bracelet holder 200 are assembled conveniently and quickly.

[0042] Furthermore, a first tooth 313 is provided at the end of the toothed claw 311, and a second tooth 333 is provided on the side of the unlocking member 330 facing the rotating wheel 310. The first tooth 313 and the second tooth 333 cooperate with each other. Specifically, when the spring piece returns to its original position and abuts against the stopper 211, the first tooth 313 and the second tooth 333 engage, thereby restricting the rotating wheel 310 from rotating counterclockwise. At this point, the bracelet assembly 100 and the bracelet frame 200 are fully assembled.

[0043] Furthermore, the connecting member 320 is a pin, and the first groove 220 is a U-shaped groove. Specifically, the curved bottom of the U-shaped groove matches the pin, and the top of the U-shaped groove can guide the pin's insertion up and down, thereby achieving quick connection and removal of the inner bracelet 110 and the bracelet frame 200.

[0044] Furthermore, connecting pins 240 are symmetrically provided on both sides of the wristband frame 200 where the mounting groove 210 is not provided. Specifically, this embodiment is connected to the surgical instrument through the connecting pins 240.

[0045] Furthermore, the two ends of the wristband 120 are connected by a fastener 130. Specifically, in this embodiment, the length of the wristband 120 can be adjusted by the fastener 130, which is convenient for adjustment.

[0046] Furthermore, a groove is provided at the free end of the connecting member 320 .

[0047] The present application can realize the rapid disassembly and assembly of surgical instruments, and increase their one-handed operability and comfort.

[0048] When it is necessary to operate surgical instruments, the doctor adjusts the bracelet strap 120 according to the wrist size to wear the bracelet assembly 100, and then presses the connectors 320 on both sides of the inner bracelet 110 into the first grooves 220. At this time, the connectors 320 drive the rotating wheel 310 to rotate a tooth claw 311 clockwise. During the rotation process, the rotating wheel 310 can push open the spring piece. Until the connecting member 320 is stuck in the first groove 220, the first tooth 313 of a tooth claw 311 on the rotating wheel 310 will be stuck on the second tooth 333 of the spring, and the connecting member 320 will be stuck in the clamping groove 312 of the rotating wheel 310, thereby realizing the self-locking of the wristband assembly 100, and the doctor can operate the surgical instrument with one hand; when the doctor suspends the use of the surgical instrument, the wristband assembly 100 can be unlocked by pressing the spring (that is, the first tooth 313 and the second tooth 333 are disengaged, thereby pulling the connecting member 320 upward, causing the rotating wheel 310 to rotate counterclockwise until the connecting member 320 is removed from the first groove 220), thereby realizing the quick disassembly of the inner wristband 110 part and the fixed wristband part. The above is the entire movement process of the device.

[0049] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
