Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to an anastomotic stoma reinforcing repair piece for a tubular anastomat.
Background
The surgical reinforcing device has very wide application in surgical operations because it can cut and seal tissue and organs in a patient at the same time rapidly, and reduces the risk of such surgical procedures to a great extent and shortens the surgical time compared with the prior surgical knife/scissors. The cutting anastomosis of the tubular anastomat comprises two parts, wherein one part is a nail anvil part with an umbrella-shaped or mushroom-shaped shape, and the other part is a nail bin part of the anastomat. The nail bin part is provided with an annular nail bin and comprises more than two nail wires. The cartridge portion is also provided with an annular knife for cutting tissue. The tubular anastomat can form annular anastomotic threads on tissues and cut the tissues by using an annular knife to form circular anastomoses. The device can be used for conveniently performing end-to-end, end-to-side and side-to-side anastomosis of a lumen organ, and is commonly used for esophagus, intestine or gastrointestinal operation.
In some procedures, it is feasible to use bare staples directly, i.e., staples that are in direct contact with the patient's tissue. Because the patient's intact tissue itself prevents the staples from being detached from the combination and compensates for the slit before healing. However, for other procedures, the tissue to be stapled by the patient is too fragile for pathological or physiological reasons, making it difficult to fix the staples in the corresponding positions. Furthermore, when using a stapler, bleeding and weeping problems around the staples also need to be addressed.
One known protective measure is to use a reinforcing or stiffening material which works on the principle that a layer of absorbable stiffening material is assembled on both the staple cartridge and anvil surface of the stapler, and the material is secured to the stoma while cutting stapling is completed, protecting the delicate tissue from being torn by the staples, closing the gap between the bare staple and the tissue or vessel, thereby strengthening the stoma and reducing the risk of complications such as bleeding, weeping, etc. of the stoma. For the tubular anastomat, an anastomotic stoma reinforcing sheet with an annular or wafer-shaped structure is adopted.
When using a reinforced sheet with a stoma, according to various surgical methods, the tubular anastomat will enter the human body or tissue through the tissue incision, and at this time, the stoma reinforced sheet and the tissue cutting edge are prone to rubbing, which may cause deformation or even wrinkling of the stoma reinforced sheet, and even may cause falling-off, which is very detrimental to the anastomosis procedure, and may cause the staples to be difficult to staple effectively. During the surgical operation, the deformation or wrinkling of the reinforcement sheet may also be caused when making a purse or adjusting the position of the clamped tissue, resulting in a difficult efficient stapling of the staples.
