Automatic purse-string device

Abstract

The invention provides an automatic purse-string device, which comprises a nail cylinder and a nail warehouse, wherein the annular end face of the nail warehouse is provided with a ring of annularly arranged nail warehouse holes which are arranged radially; a line carrying groove in the circumferential direction is also arranged on the annular end face of the nail warehouse; nails are arranged ineach nail warehouse hole respectively; and purse-string lines are arranged in the line carrying groove. A nail push piece in the nail cylinder can push the nails out of the nail warehouse and make thenails shaped and fixed on a tissue to be performed with purse-string suturing. The automatic purse-string device has the main advantages that: because the nails are arranged annularly in the nail warehouse, all nails can be shaped in one plane in the process of the purse-string suturing; the automatic purse-string device has a round head, has low requirement on a surgical space range and is suitable for surgeries of high-position esophagus, low-position male pelvic cavity and the like, and can cut the tissue when suturing a purse-string, so the automatic purse-string device has extraordinarysignificance on the surgeries at special positions.

Description

technical field [0001] The invention relates to a purse-string suturing device, in particular to an automatic purse-string suturing device, which belongs to the field of medical devices. Background technique [0002] Surgical purse-string suturing device is a medical device often used in surgical operations on intestinal and other physiological tissues. The performance of the instrument directly affects the operation process and plays a very important role in the operation effect. In the prior art, when using a stapler for suturing, purse-string sutures must be performed on the stump of the organ, so that it can be firmly ligated after the central rod is inserted, and then the stapler can be implemented. There are two methods of performing purse-string suture surgery: one is manual suture, which is not only time-consuming and labor-intensive, but also the depth of the needle is different, and the needle pitch is inconsistent; the other is to use purse-string suture forceps t...

Problems solved by technology

However, the nails in the purse-sewing process of this purse device will be worn against each other, that is, the end opening of the circular tubular tissue will be closed, and the sewn purse will be unqualified, which will affect the follow-up procedures; and because the existing automatic purse device requires the implementation of The surgical area is large enough to be inserted, so the scope of its application is limited. For special tissues such as the esophagus, because it only sutures the outer surface of the tissue, the inner and outer layers of the tissue slip. The application effect of this device is not good for special parts such as surgery
