Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a soft tissue clamp with a rotating structure. Background Art

[0002] In clinical practice, a metal clip device is often used to seal some tissue bleeding or perforation under digestive endoscopy. The two clips of the clip clamp the tissue to achieve the purpose of sealing the tissue wound.

[0003] According to a soft tissue clamp rotating handle disclosed in Chinese patent CN202120924749.0, the application includes a core rod, a handle, a roller, an end cap, and a cable. The core rod is provided with a support seat and a slot, and the end cap is provided with a buckle, and the end cap is adapted to be connected with the core rod slot through the buckle; a limiting hole and a circular supporting hole are provided at the center of the roller, and the supporting hole is adapted to the support seat of the core rod. The roller is connected to the core rod support seat through the supporting hole, and an elliptical supporting tube adapted to the limiting hole is provided in the limiting hole, and the supporting tube is fixedly connected to the cable; the pull sleeve is connected to the core rod, the handle is provided with two symmetrically arranged fixing holes, and a card is provided inside the handle, and a card head adapted to the fixing hole is provided at the front end of the card, and a fixing groove is provided at the bottom end of the card, and a fixing tube is embedded in the fixing groove, and the fixing tube is fixedly connected to the support tube. When the handle is rotated to control the rotation of the chuck, there is no need to rotate the entire handle. The existing soft tissue clamp drives the chuck to rotate and adjust the position by rotating the roller.

If the person's hand keeps holding the roller for a long time, it will cause wrist soreness. At the same time, the existing soft tissue clamp requires the person to manually push the handle when clamping, which is more laborious.

When the rotating wheel 5 stops rotating, the reset spring 13 resets and drives the limit block 15 to insert into the tooth groove of the annular limit gear 16 to limit it. By setting a damping component, when the rotating wheel rotates Afterwards, it can be automatically limited to prevent the automatic rotation of the wheel and the deflection of the chuck. There is no need for personnel to hold the wheel for a long time, which reduces labor. When the chuck needs to be closed to clamp soft tissue, the switch key 24 is pressed to start the servo motor 21. The servo motor 21 drives the screw rod 18 to rotate. The screw rod 18 is threadedly connected to the movable sleeve 19. The movable sleeve 19 is limited by the rotation of the guide block 22. The rotation of the screw rod 18 drives the movable sleeve 19 to move. The movable sleeve 19 starts to pull the pull core 9 so that the chuck 8 starts to close and clamp the soft tissue. By setting a stretching component, the chuck can be electrically controlled to open and close to clamp the soft component. There is no need for personnel to manually pull the pull core to drive the chuck to close, which reduces labor and is more convenient to use.

[0037] In summary, with the aid of the above-mentioned technical scheme of the utility model, by setting a damping component, the rotary wheel can be automatically limited after it rotates to prevent the rotary wheel from automatically rotating and causing the chuck to deflect. There is no need for personnel to hold the rotary wheel for a long time, which reduces the workload. By setting a stretching component, the chuck can be electrically controlled to open and close the soft component. There is no need for personnel to manually pull the pull core to drive the chuck to close, which reduces the workload and is more convenient to use.
