Description

Non-closed circular anastomosis

The present invention relates to a non-closed circular anastomosis, and more particularly, to a non-closed circular anastomosis that can effectively prevent pain and bleeding due to stenosis of the cutting tissue after surgery.

Anastomosis refers to a condition in which blood vessels, nerves, or organs are connected. For example, if a blood vessel going to a specific cell group is wounded or fat accumulates and the blood flow cannot flow, all of that cell group is forced to die. To prevent that, the other blood vessel is anastomotic from the beginning or a new capillary is formed. A new anastomosis will appear. It is said that anastomosis also involves methods such as connecting nerves with surgical operations or cutting parts of the small intestine and connecting them to the large intestine. Until recently, simple anastomosis by classical suture has been performed, and it is one of the most commonly performed procedures. However, in the case of such sutures, stenosis of the anastomosis site occurs in many cases due to complications due to leakage of the anastomosis site and secondary changes resulting from the suture surgery, which is an important factor affecting patient prognosis. Is recognized.

Hemorrhoids refer to a lump of blood vessels in which the vein layer in which the veins inside the anus are gathered is stretched with continuous stimulation, and the mucous membrane covering it is stretched together. Hemorrhoid surgery has various methods, but in recent years, PPH (circular automatic anastomosis) surgery has been spotlighted as a hemorrhoidal surgery with less pain. Unlike the conventional hemorrhoidal surgery method, surgery using a circular automatic anastomosis is performed on the dendritic 2 ~ 3cm in the anus, the upper part of the nerve that has no nerve development. The circular automatic anastomosis machine automatically excises and sutures the sagging hemorrhoids and returns it to its original position, whereby surgery is performed on the rectal mucosa without the sensory nerve endings. The circular automatic anastomosis machine (PPH) roughly includes a head portion, an extension portion, and a handle portion. Briefly, a part of the extension portion is inserted into the body through the anus together with the head portion, and then, an organ resected by a plurality of staples provided in the head portion according to the manipulation of the lever of the handle portion may be joined. Since such a circular automatic anastomosis device (or a circular anastomosis device) is a well-known device, a detailed description thereof will be omitted. The hemorrhoidal surgery using a circular anastomosis is less painful and has fewer wounds on the surgical site. However, if the hemorrhoids are excised in a closed circle using a circular anastomosis device, the excised tissue contracts during the wounding process, and stenosis may occur, which may cause pain and bleeding.

Korean Registered Patent No. 10-0769681 (2007.10.17) converts the rotational motion of a small motor into a linear motion, attaches a strain gauge, measures the amount of micro-deformation that occurs during compression in real time, and then measures the rotational speed of the motor. Compared with fuzzy control, optimized compression force suitable for the patient's unique biomechanical characteristics such as organ thickness and viscoelastic characteristics, and conventional mechanical anastomosis can be caused by adjusting the compression interval by the operator's subject. In addition to drastically reducing secondary lesions such as stenosis, the handle member and the control unit can be used semi-permanently, thereby dramatically reducing costs.

Korean Registered Patent No. 10-1350203 (2014.01.06) relates to an intraluminal surgical anastomosis device that provides the creation of an elliptical shape during anastomosis, and is an elliptical surgical anastomosis device including a head in which a plurality of staples are stored. Heads with opposing surfaces are oriented inclined relative to the longitudinal axis of the head creating an elliptical staple line when the anvil comes into contact during operation of the surgical anastomosis device, and dimensioned to form staples simultaneously with the operation of the surgical anastomosis device. It has a shaped anvil surface and is inclined with respect to the longitudinal axis of the head creating an elliptical staple line, which is placed through the anus by placing the instrument through the rectum and positioning the anvil on the distal end of the anastomosis. In addition, the proximal end of the intestine is bound to the anvil shaft, the cut tissue is incised adjacent to the tie, and the surgeon can attach the anvil to the trocar shaft of the intraluminal surgical anastomosis.
