Abstract

The invention discloses a portable needle-holding stitching device for cavity mirror. The portable needle-holding stitching device comprises a handle body and an arc-shaped needle, wherein a pair of rotating forceps arms matched with each other are arranged on the first end of the handle body, a first driving device and a second driving device, which drive the inner ends of a pair of the rotatingforceps arms to rotate around the handle body are respectively arranged on the second end of the handle body; the outer end of the rotating forceps arms is provided with a pinhole for the arc-shaped needle to pass through; the pinhole is internally provided with a one-way limiting device which limits the arc-shaped needle to penetrate through the pinhole in a one-way way, and the sides of the over-hole are also provided with slots for withdrawing the suture respectively. The portable needle-holding stitching device for cavity mirror reduces the pulling damage to the tissue during stitching. And after the suture passes through the tissue, the needle is not required to be taken out of the body cavity to be re-clamped, but only needs to rotate the forceps arm repeatedly around the handle body, then the needle can be repositioned for the next stitch which is beneficial to continuous suture or the eight-word suture.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a needle-holding suturing device for a portable endoscope. Background technique [0002] With the deepening of the concept of minimally invasive surgery and the advancement of instrumental surgery and surgical technology, video-assisted laparoscopic surgery has been widely used in clinical practice. Laparoscopic surgery has high technical requirements, complex operation, and various instruments used in the operation. Among them, the endoscopic needle holder is a routinely used needle holding instrument in the minimally invasive surgery. Due to the small incision and limited field of view of minimally invasive surgery, multiple instruments are often used in conjunction with the operation during the operation, and surgical instruments are frequently replaced. The existing needle holder is a long-handled forceps structure, and continuous suturing needs to go through: holding the ...
