The invention relates to a medical suturing device and a safety device thereof. The safety device comprises a safety support plate, a safety block, a resetting block and a safety reversing block, wherein the safety block comprises a plate body and an elastic arm, the elastic arm is connected with the plate body, the safety block is slide between a first position and a second position along the safety support plate, the resetting block is movably arranged on the safety support plate and comprises a plate body abutting end, a safety control end and an elastic arm operating end, and the safety reversing block is arranged on the safety support plate in a pivoting way and comprises a limiting part; when the safety block is in the first position, the plate body abutting end is abutted against the plate body to enable the safety control plate to be in the closing position; when the safety block is in the second position, the limiting part is used for limiting the elastic arm to enable the safety control end to be in the opening position; when the safety block is reset from the second position to the first position, the elastic arm operating end drives the elastic arm to move, so as to release the limiting of the limiting part on the elastic arm, and reset the safety block to the first position. The safety device has the advantages that the false operation effectively avoided, and the safety is improved.
Description
technical field [0001] The invention relates to the field of medical instruments, and more specifically, to a medical stapler and a safety device thereof. Background technique [0002] In surgical operations, medical staplers have become an indispensable auxiliary medical device in the process of suturing human tissue. With the development of medicine and product research and development, more and more multifunctional staple products are used in clinical practice. One of the few tools. The application of medical stapler has many advantages such as less bleeding during operation, shorter operation time, reduction of manual operation error, avoidance of infection, and quick recovery of postoperative function. [0003] The linear cutting stapler is one of the more commonly used medical staplers, which is used for the transection and anastomosis of tissues. However, because the existing linear cutting stapler does not have a safety device, or the safety device has a structura...
