Embodiment

[0025] Such as Figure 1~3 As shown, an endoscopic intestinal anastomotic stricture resection device, including

[0026] The metal sheath 5 is provided with a second elastic metal cutting piece 4 on the front end wall of the metal sheath 5; the metal sheath 5 transmits electricity to the second elastic metal cutting piece 4 to heat it.

[0027] Steel wire 3, the steel wire 3 runs through the inside of the metal sheath 5; the front end of the steel wire 3 is provided with a first elastic metal cutting piece 2; the steel wire 3 transmits electricity to the first elastic metal cutting piece 2 to heat it.

[0028] The first elastic metal cutting piece 2 and the second elastic metal cutting piece 4 are arranged in an umbrella structure. The umbrella structure is convenient for the outer tube 6 to compress the first elastic metal cutting piece 2 and the second elastic metal cutting piece 4, and it is convenient to insert the front end of the device into the intestinal tract.

Abstract

The invention discloses an endoscopic lower intestinal tract anastomotic stoma stenosis resection device. The device comprises a metal sheath tube, a steel wire, a control handle and an outer tube, wherein a second elastic metal cutting blade is arranged on the tube wall of the front end of the metal sheath tube; the steel wire penetrates through the interior of the metal sheath tube; a first elastic metal cutting blade is arranged at the front end of the steel wire; the control handle is mounted at the tail end of the metal sheath tube, connected with the steel wire and used for controlling the steel wire to be pulled; the outer tube is connected to the outside the metal sheath tube in a sleeving and sliding manner and is used for controlling the contraction or expansion of the first elastic metal cutting blade and the second elastic metal cutting blade; and the device further comprises a power input end. According to a hot excision principle, the distance between the first elastic metal cutting blade and the second elastic metal cutting blade is controlled and tightened, hot excision is carried out on the two ends of a membranous stenosis of an anastomotic stoma under an endoscope, excision of a stenosis part can be completed at a time, and the device has the advantages of being short in time, little in patient pain, thorough in excision and the like.

Description

technical field [0001] The invention relates to the technical field of medical operation instruments, in particular to an endoscopic intestinal anastomotic stricture resection device. Background technique [0002] With the clinical application of anastomotic instruments, the popularization of laparoscopic technology and the promotion of the concept of neoadjuvant therapy, anterior rectal resection has gradually become the main surgical treatment for middle and low rectal cancer. However, this operation still brings some serious complications, such as anastomotic stenosis, anastomotic leakage, anastomotic bleeding, anterior resection syndrome, urinary and sexual dysfunction, etc. Among them, anastomotic stenosis is a late complication, which is difficult to deal with and the treatment effect is unsatisfactory. It has become a hot spot for specialist doctors. [0003] Anastomotic membranous benign stricture is a common complication in postoperative patients with colorectal ca...
