Embodiment Construction

[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 ...

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.

Description

Technical field [0001] The invention relates to a medical linear closure, which belongs to the field of medical equipment. Background technique [0002] At present, when performing surgical anastomosis on physiological tissues such as the esophagus, stomach, intestine, etc., surgical staplers are often used for anastomosis. Among them, the medical linear closure is a more important one. In the prior art, referring to US Pat. No. 7,407,076, a medical linear occluder is used to close the digestive tract and visceral tissue wounds. It generally includes a shell, a stent fixed in the shell, a nail anvil placed at the distal end of the stent, and The staple cartridge, and the firing handle pivoted on the bracket. The operation process is roughly as follows: first put the tissue between the nail anvil and the nail cartridge, then squeeze the firing handle, the nail cartridge will move closer to the nail anvil and clamp the tissue; then release the firing handle, and then push the nail...
