What is a disposable circular stapler?

The disposable circular stapler is a medical alternative to traditional manual suturing. disposable circular stapler is similar to a stapler in that it consists of a number of small titanium staples arranged at regular intervals in 2 circles (or 2 rows) on a specially designed instrument. The two legs of the titanium staples close after excitation, thus connecting the two segments of the intestinal canal, while there is a circle of small blades between the two circles of titanium staples, which can cut the mucosa between the two circles, thus completing the anastomosis.

What are the types of disposable circular stapler?

1、According to the origin: imported disposable circular stapler and domestic disposable circular stapler.

2、According to the shape is divided into: curved disposable circular stapler, straight disposable circular stapler, and straight type closure.

3, according to the design purpose can be divided into: anastomosis, closure, cutting closure, linear lateral closure.

What are the advantages of using disposable circular stapler?

1、Suture is fast and easy to operate, which shortens the operation time and facilitates the recovery of patients after surgery.

2、The suture is indeed and precise, which reduces the incidence of surgical complications.

3、The material of the anastomotic staple of disposable circular stapler is titanium alloy, which has better histocompatibility than silk thread, light foreign body reaction, and lower incidence of anastomotic leakage than manual suturing.

4、The use of disposable circular stapler reduces the difficulty of surgery and makes it possible to perform surgeries that were difficult in the past, such as resection anastomosis of ultra-low rectal cancer.

5、The use of disposable circular stapler also allows for some completely new surgical procedures: such as PPH (anastomotic suprahemorrhoidal mucosal circumferential resection and stapling.) PPH is a treatment for severe mixed hemorrhoids. Before the advent of PPH, severe mixed hemorrhoids needed to be treated surgically with external stripping and internal stapling, which is very invasive, bleeds a lot, takes a long time to operate, is painful and has many complications. PPH lifts the hemorrhoid that has prolapsed into the anus into the rectum by cutting off a ring of rectal mucosa above the hemorrhoid (about 2-4 cm above the dentate line). The procedure is simple and quick, with good surgical results, mild pain and quick recovery.

PPH surgery procedure.

1、After anesthesia, the anus is fully dilated with a specially designed anal dilator.

2、Make a loop of purse-string suture on the dentate line 2-4cm.

3、Place the disposable circular stapler for PPH and tighten the bag.

4、Stimulate the disposable circular stapler and remove a circle of rectal mucosa, thus lifting the hemorrhoid into the rectum.
