Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an anastomosis component of a circumcision stapler. Background Art

[0002] The circumcision stapler is a medical device often used in surgical operations on the foreskin tissue of the male penis. In general surgical treatment, the circumcision stapler is often used to complete the cutting and closing function of the tissue. The working principle of the circumcision stapler is to place the tissue between the stapler group and the anvil group, and reasonably compress the tissue by adjusting the distance between the stapler group and the anvil group. When the distance between the stapler group and the anvil group reaches the safe range for effective suturing, it fires, compresses the U-shaped staples into a D-shape to suture the tissue and prevent bleeding.

[0003] In order to facilitate the use of personnel, some manufacturers in the market sell electric circumcision staplers to replace manual circumcision staplers for performing surgery on patients. The existing electric circumcision staplers mostly use motors as power sources, which are often used in conjunction with gear sets or screw structures to drive the transmission rod and the anastomosis head to move, so as to complete the circumcision surgery on the patient. However, the existing electric circumcision staplers mostly only limit and guide the transmission rod through some through-hole structures, and the transmission force of the electric circumcision stapler is often large. There is a lack of limiting and guiding the transmission rod only through the through-hole structure, which will affect the accuracy of positioning the anastomosis head and the male penis by medical staff. Therefore, there are certain shortcomings.

[0004] In summary, it is necessary to invent an anastomosis assembly for a circumcision stapler. Utility Model Content
