Problems solved by technology

[0002] Conventional external hemorrhoidectomy has the following problems: large wound, heavy bleeding, difficult ligation, severe postoperative pain, and slow repair (about 20 days)
However, surgical sutures often have inaccurate alignment, and the needle penetrates deeper into the tissue, which is prone to infection after surgery.
More importantly, it is difficult to remove stitches after surgery, which brings secondary pain to patients.

Description

1. Technical field: [0001] The invention relates to the technical field of medical instruments; in particular, it relates to a suture-free suture forceps for excision of external hemorrhoids. 2. Background technology: [0002] Conventional external hemorrhoidectomy has the following problems: large wound, heavy bleeding, difficult ligation, severe postoperative pain, and slow repair (about 20 days). So some hospitals use excision and suture. However, inaccurate alignment often occurs in surgical sutures, and the needles penetrate deeply into the tissue, which is prone to postoperative infection. More importantly, it is difficult to remove the stitches after the operation, which brings secondary pain to the patient. 3. Contents of the invention: [0003] The present invention is made up of pincer handle, pincer tooth, self-locking mechanism. The cross-section of the paired teeth of the two forceps is in the shape of an "eight", the upper edges touch, the lower edges sepa...
