Abstract

The invention provides a medical linear type closer. The closer comprises a bracket, a nail anvil, a nail cabin, a transmission device and a firing handle, wherein the nail anvil and the nail cabin are arranged at the remote end of the bracket and are used for realizing sewing-up operation; the transmission device is arranged in the bracket and is used for pushing the nail cabin and nails in the nail cabin; the firing handle is pivotally arranged on the bracket through a rotating shaft and is connected to the transmission device; and a limiting prompt device is arranged between the bracket and the firing handle and used for limiting rotation of the firing handle around the rotating shaft. The closer has the main advantage of effectively prompting a user to press the handle with proper force so as to prevent the firing handle from being broken off due to overlarge force, and is safe and reliable.

Example Embodiment

[0017] The invention discloses a medical linear closure, such as figure 1 As shown, consistent with the prior art, it includes: a stent 1, a nail anvil and a staple cartridge arranged at the distal end of the stent 1 and used to implement a suture operation, and a nail anvil and a staple cartridge arranged in the stent 1 and used to push the staple cartridge and the staples. The nail transmission device in the bin, and the firing handle 3 pivotally arranged on the bracket 1 through a rotating shaft 6 and connected to the transmission device.

[0018] A limit reminding device for restricting the rotation of the firing handle 3 around the rotation axis 6 is arranged between the support 1 and the firing handle 3. Further, the limit reminding device includes a lower plane 2 of the bracket 1 and a limit boss 4 arranged on the firing handle 3. The top surface 5 of the limit boss 4 and the bracket The lower plane 2 abuts, and when the firing handle is squeezed to the end, there will be an obvious hand feeling to remind the user that the firing is in place. Such as figure 2 As shown, at this time, the top surface 5 of the limiting boss 4 and the lower plane 2 of the bracket are substantially parallel and close to each other.

[0019] Further, the limiting boss 4 and the handle are integrally molded by injection molding, or welded to the firing handle 3, or directly punched out of the firing handle 3. These can be determined by the cost or the material of the handle of the medical linear closure.

[0020] The present invention still has a variety of specific implementation modes, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of the present invention.
