Description

Sample snare fixer for surgical minimally invasive surgery
Technical Field
The invention relates to the technical field of medical instruments, in particular to a specimen snare fixer for a surgical minimally invasive surgery.
Background
At present, in the prior art, laparoscopic minimally invasive surgery is a common surgical method, and during surgical operation, a minimally invasive surgical instrument with a long handle is required to move cut human tissues out of a human body through a minimally invasive hole.
A Chinese patent 201110268726X published on 9/11/2011 discloses a minimally invasive surgery specimen extractor, which is a minimally invasive surgery instrument used for conveniently and completely extracting a cut specimen from a surgical cavity in a minimally invasive surgery. The surgical instrument consists of a sleeve, a core barrel, a clamping strip and a specimen bag, wherein the sleeve is a hollow tubular passage for other components to enter and exit the surgical cavity; the core barrel is formed by connecting four stainless steel long and narrow sheets at one end to form a barrel shape, a traction wire is fixed in the center of the bottom of the core barrel, a traction ring is arranged at the other end of the traction wire to facilitate traction, and a clamping groove is formed in one sheet and used for inserting a clamping strip; the clamping strip is a long and narrow stainless steel strip, the appearance is matched with the clamping groove on the core barrel, the clamping groove can be inserted and fixed, a barb is arranged at the position, close to the bottom end, of the clamping strip and used for fixing the opening of the specimen bag, and the specimen bag body is wrapped at the bottom end of the core barrel and used for containing a specimen. However, the structure of the specimen extractor is too complex, the operation process is too complicated, the cost is too high, and the specimen extractor is not beneficial to wide popularization in medical science.
It can be seen that the existing sample extractor for minimally invasive surgery has the following defects:
after the sample is cut down, put the sample in the sample bag, pull out the sample bag through the Trocar hole, the gesture that the sample passed through the Trocar hole is random: may be horizontal, vertical, may have a large side facing outward, and may have a small side facing outward. It is difficult to pull the specimen out of the relatively small Trocar aperture when the specimen is positioned under the incision laterally or large side-out. Taking large specimens through minimally invasive holes not exceeding 5cm in diameter is cumbersome if special instruments are not used. The physician may then grasp and pull the specimen by enlarging the incision or by pulling the specimen bag hard to see the specimen. However, enlarging the incision does not comply with the minimally invasive principle; the forceful pulling may cause the specimen bag to break and the specimen to flow into the abdominal cavity; causing pollution and not meeting the requirements of the non-tumor technology.
