Description

Technical Field

[0001] The present invention relates to the technical field related to the treatment of hemorrhoids, and particularly to a titanium staple ligation anastomosis device. Background Art

[0002] Hemorrhoids, also known as piles, are one of the most common anorectal diseases clinically. Hemorrhoids are the pathological hypertrophy of the anal cushions at the lower end of the rectum. According to the different occurrence sites, hemorrhoids can be divided into internal hemorrhoids, external hemorrhoids and mixed hemorrhoids. During the treatment of hemorrhoids, an anastomosis device needs to be used in cooperation to treat the patient, improving the surgical comfort of the patient.

[0003] Currently, the existing first-generation and second-generation ligation anastomosis devices utilize the negative pressure principle. Through a specially designed disposable hemorrhoid ligation anastomosis device, a specially designed rubber ring / elastic thread is sleeved at the base of the hemorrhoid or the mucosa above the hemorrhoid at an appropriate position. Through the tightening and strangulation of the rubber ring, the blood supply of the hemorrhoid is blocked or the venous backflow is reduced, reducing the congestion and hypertrophy of the hemorrhoid or blood stasis, causing ischemia, atrophy and necrosis. The ligated tissue gradually falls off, and the wound tissue repairs and heals. It is applicable to the ligation treatment of internal hemorrhoids, mixed hemorrhoids or rectal benign polyps in all stages.

[0004] The traditional devices have the following deficiencies: However, the mechanical properties of the first-generation special latex ring ligation anastomosis device are poor. The latex ring is stretched and sleeved at the gun head for a long time, resulting in deformation. When in use, the latex ring is difficult to restore to its initial tightness, thus reducing the performance of blocking the blood supply of the hemorrhoid. Moreover, the biocompatibility of the latex ring is poor and may react with people allergic to latex, so it is not suitable for use.

[0005] For the second-generation elastic thread ligation anastomosis device, the elastic thread needs to be manually installed on the gun head. After the hemorrhoid is inhaled, the elastic thread is sleeved on and manually tightened. After fixing, the excess elastic thread is cut off. This generation of ligation anastomosis device has poor mechanical properties, requires multiple manual operations to complete, has low convenience, and the biocompatibility of the elastic thread is poor.

[0044] Working principle: When in use, the detachable gun body 2 is provided to facilitate the installation by the staff and subsequent separate disassembly and replacement, reducing the operation difficulty of the staff. The negative pressure connector 7 is connected to an external negative pressure device to ensure the efficient progress of subsequent processing work. By providing an adsorption and fixation component, the staple cartridge sleeve 6 is brought close to the patient's hemorrhoids, and then the negative pressure button 8 is pressed, causing the external negative pressure device to perform air extraction work.

The firing handle 18 drives the push block 21 to move during movement, driving the push piece 20 to move to open the air release valve 22, enabling the external air pressure to be increased and conveyed into the second inner sleeve 24 to provide power for the staple pushing piece 25. The U-shaped titanium staples reserved on the staple pushing piece 25 are moved, and the U-shaped titanium staples are respectively inserted into the upper and lower layers of the spiral grooves of the spiral groove anvil 15 to form a titanium alloy spiral ring, strangling and blocking the blood supply of the hemorrhoids or reducing venous backflow, reducing the congestion and hypertrophy of the hemorrhoids or blood stasis, causing ischemia, atrophy, and necrosis, and the ligated tissue gradually falls off, and the wound tissue is repaired and healed. With the assistance of the acceleration and reset component, when the firing handle 18 is pressed, it contacts the push head 28, driving the sliding part 27 to contract in the built-in cavity 26, and at the same time compressing the reset spring 29. After the subsequent operation is completed, the reset spring 29 resets, driving the sliding part 27 and the push head 28 to reset, accelerating the rapid reset of the firing handle 18 and facilitating the subsequent operation and use by the staff.
