Anastomosis assembly, nail bin containing anastomosis assembly and anastomat

Abstract

The invention discloses an anastomosis assembly. The anastomosis assembly comprises a plurality of nail bodies made of a high polymer material and a plurality of nail sleeves which are made of a highpolymer material and matched with the nail bodies in number and position; the nail body comprises a nail head, and each nail head is connected with the adjacent nail head through a macromolecule lineto form a net structure; a nail rod is positioned below the nail head; the nail foot is provided with one or more stages of inverted teeth, and the end part of the nail foot is pointed; moreover, thenail sleeve is provided with a through hole corresponding to the nail foot in shape and size so that the nail foot can be clamped into the through hole, the nail sleeve is provided with one or more levels of gears corresponding to the inverted teeth of the nail foot, and the distance between the nail foot and the nail sleeve can be adjusted through clamping connection between the one or more levels of inverted teeth and the one or more levels of gears. The anastomosis assembly can be absorbed by a human body, the strength is high, the stability is good, and the nailing height can be adjusted according to the height of tissue so as to solve the problems of tissue bleeding and blood supply after nailing.

Description

technical field [0001] The present invention relates to a surgical medical instrument, more specifically, to a stapling assembly, a staple cartridge including the same, and a stapler. Background technique [0002] During surgery, when the doctor uses staplers to staple the lungs, liver, stomach, fascia, muscles, tendons, subcutaneous tissue, digestive tract (including esophagus, intestinal tract), etc., the nail piece is driven forward by the nail driving device. During the moving process, the stapler in the staple cartridge is pushed out of the inner cavity of the staple cartridge, and interlaced staples are fired and implanted into the tissue to perform cross-stitching of the tissue, so that the human tissues to be stapled are stapled together, and the staples Tight fit to prevent leakage. Anastomotic nails are mainly titanium nails, which are two-dimensional planar materials. The advantage is strong toughness, but the disadvantage is that the shape is not satisfactory, a...

AI Technical Summary

Problems solved by technology

Anastomotic nails are mainly titanium nails, which are two-dimensional planar materials. The advantage is strong toughness, but the disadvantage is that the shape is not satisfactory, and it is difficult to meet the satisfaction requirements of patients and operators. There are metal artifacts in postoperative clinical medical images.

Compared with manual sutures, the tissue reaction is small, but because the staples that exist in the body for a long time will not be absorbed by the body, sequelae are prone to occur after surgery

[0003] In addition, the bleeding during the operation is serious, so all kinds of doctors attach great importance to the bleeding problem. The analysis of the bleeding after stapler stapling found that if the closure height of the stapler is too high, the tissue contained in the staple circle cannot Compression of larger blood vessels will cause bleeding at the cutting edge, and too low closure height of staples will also cause crushing damage to the tissue and bleeding

Sometimes, although the staples meet the requirements of hemostasis, the incised end of some tissues often still has local bleeding, especially when there are different tissue thicknesses in the same part, the probability of bleeding or tissue crushing injury will change. After a lot of research, it is believed that, The current method of arranging the staples is difficult to avoid bleeding from the incisal end, and the gap between the two staples and the gap between the two forming rings of the "B"-shaped staples still have hemostatic weaknesses
