Referring to fig. 4 and 5, in the preferred embodiment, the end surface of the cutting portion 203 and the end surface of the extending portion 102 are both provided with a safety cap 120, and before the two are matched, the safety cap 120 can ensure safety and prevent the device from being damaged or accidentally injured.

The foregoing is a structural description of the present invention, and the present invention will be further described with reference to specific embodiments thereof.

The utility model is used for the anastomosis of the urethra and the bladder, and before the use, in order to facilitate the use of the urethra anastomat, the junction part of the prostate and the bladder is properly kept long in the prostate resection operation process.

When the device is used specifically, the base part 1 of the utility model is placed into the remaining long part, the remaining long part and the rear end of the extension part 102 are wound and fixed together by cotton threads, the safety cap 120 is checked and covered, then the long neck 202 and the cutting part 203 of the operation part 2 extend into the body from the urethra outside the body until the cutting parts of the prostate and the urethra are reached, the safety cap 120 is taken down, and the extension part 102 is aligned and extended into the hollow part 204.

When anastomosis is started, the handle 205 is held by one hand with force to ensure that the urethra anastomat does not shake as a whole, the auxiliary rotating part 201 (namely the adjusting nut in the embodiment) is rotated by the other hand to drive the long neck 202 to rotate, the long neck 202 drives the extension part 102 to go deep into the hollow part 204 through the matching of the threads, and when the indication line 208 in the indication window 206 is observed to be positioned at a half of the progress bar 207 (namely, when a half of the extension part 102 enters the hollow part 204), the urethra is connected with the rear end of the extension part 102 by cotton threads.

Then, the rotation-assisted component 201 is rotated continuously until the end face of the long neck 202 is completely matched with the end face of the base 101, at this time, the top blade of the cutting part 203 is matched with the bottom blade of the gap part 103, the urethra and the remaining length part are cut simultaneously, and simultaneously, the titanium nails (medical titanium nails) in the nail bin 104 are driven to collide with the steel transverse section of the long neck 202 due to the spiral force between the long neck 202 and the extension part 102, so that the titanium nails are fixed on the urethra and the remaining length part.

When the long neck 202 is taken out, the rotation assisting component 201 is turned for a half turn, then is twisted back, and is repeatedly turned for three times or more, so that the urethra and the remaining part are completely cut by the blade, and then the long neck is taken out.

In conclusion, the urethra anastomosing device can be used for anastomosing the urethra and the bladder after the operation, and the defects that the urethra and the bladder are difficult to anastomose and no special anastomat is used for assisting in the prior art are overcome. The utility model has simple structure, convenient operation and low production cost, and is suitable for being widely applied to urinary surgery.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
