Abstract

The present invention provides a medical linear closer, comprising: a bracket, a nail anvil and a staple bin arranged at the far end of the bracket and used for suturing operations, arranged in the bracket and used to push the nail bin and the nail bin The transmission device of the nail in the warehouse, and the firing handle that is pivotally arranged on the bracket and connected to the transmission device through a rotating shaft, and a device for limiting the firing handle is arranged between the bracket and the firing handle. A limit reminding device that rotates around the rotation axis. The beneficial effects of the present invention are mainly reflected in that the user can be effectively prompted to press the handle with an appropriate force, thereby avoiding the breaking of the firing handle due to excessive force, which is safe and reliable.

Description

Medical Linear Closer

technical field

The invention relates to a medical linear closer, which belongs to the field of medical instruments.

Background technique

At present, when performing surgical anastomosis on physiological tissues such as the esophagus, stomach, and intestinal tract, a surgical stapler is often used for anastomosis, and a medical linear closer is a relatively important one. In the prior art, with reference to U.S. Patent No. 7,407,076, a medical linear closer is described, which is used to close the wounds of the digestive tract and visceral tissues. It generally includes an outer shell, a bracket fixed in the outer shell, an anvil and The staple cartridge, and the firing handle pivotally placed on the bracket. The operation process is roughly as follows: First, the tissue is placed between the anvil and the staple cartridge, and then the firing handle is squeezed, and the staple cartridge moves toward the anvil and clamps the tissue; then the firing handle is released, and the push nails placed in the bracket are released at this time. After the mechanism is ready, squeeze the firing handle again, and the nail pushing mechanism pushes the nail out of the nail bin, and forms it on the tissue to achieve the closing effect.

However, during the operation, since the medical linear closer of the prior art does not have any reminder device to remind the user that the firing is in place, the doctor will squeeze the handle hard after the firing is in place, causing the firing handle to be easily broken.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned technical problems, and provide a medical linear closer that reminds the user that the firing is in place and has high safety.

The purpose of the present invention is achieved through the following technical solutions:

A medical linear closer, comprising: a bracket, a nail anvil and a staple bin arranged at the distal end of the bracket for suturing operations, and a staple bin arranged in the bracket and used to push the nail bin and the nail bin The transmission device, and the firing handle that is pivotally arranged on the bracket and connected to the transmission device through a rotating shaft, and there is a device between the bracket and the firing handle to limit the rotation of the firing handle around the Limit reminder device for shaft rotation.

Further, the limit reminder device includes the lower plane of the bracket and a limit boss arranged on the firing handle, the top surface of the limit boss abuts against the lower plane of the bracket to limit When the firing handle rotates around the rotation axis, there will be an obvious feel prompt to remind the user that the firing is in place.

Further, when the firing handle is restricted from rotating, the top surface of the limiting boss is approximately parallel to the lower plane of the bracket and close to it.

Further, the limiting boss and the handle are integrally molded, or welded to the firing handle, or punched directly from the firing handle.

The beneficial effects of the present invention are mainly reflected in that: the user can be effectively reminded that the firing is in place, the firing handle does not need to be pressed with excessive force, and the firing handle is protected from being broken, which is safe and reliable.

Detailed ways

The present invention discloses a medical linear closer. As shown in FIG. 1, it is consistent with the prior art, including: a bracket 1, a nail anvil and a nail magazine arranged at the distal end of the bracket 1 and used for suturing operations, and a set A transmission device inside the bracket 1 and used to push the staple cartridge and the nails in the staple cartridge, and a firing handle 3 pivotally arranged on the bracket 1 through a rotating shaft 6 and connected to the transmission device .

A limit reminder device for limiting the rotation of the firing handle 3 around the rotation axis 6 is provided between the bracket 1 and the firing handle 3 . Further, the limit reminding device includes the bracket lower plane 2 of the bracket 1 and the limit boss 4 arranged on the firing handle 3, the top surface 5 of the limit boss 4 is in contact with the bracket The lower plane 2 abuts, and when the firing handle is squeezed to the bottom, there will be an obvious feel to remind the user that the firing is in place. As shown in FIG. 2 , at this time, the top surface 5 of the position-limiting boss 4 is approximately parallel to and close to the lower plane 2 of the bracket.

Further, the limiting boss 4 is integrally injected with the handle, or welded to the firing handle 3 , or punched out directly from the firing handle 3 . These may be determined by cost or the material of the medical linear closer handle.

The present invention still has many specific implementation modes, and all technical solutions formed by adopting equivalent replacement or equivalent transformation all fall within the protection scope of the present invention.
