Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention will be further described.

[0024] see Figure 1-5 As shown, the technical solution adopted in this specific embodiment is: it includes the trocar 1 and the awl core passing through the trocar 1;

[0025] Described cone core comprises cone cover 15 and cone rod 16; Cone cover 15 adopts convex structure, and the inner central part of convex structure is connected with the upper end of cone rod 16; The end of cone rod 16 is sharp; The height of cone rod 16 is greater than The height with the trocar 1;

[0026] The trocar 1 is a tubular structure made of flexible materials; the upper and lower inner walls of the trocar 1 are solid structures, and the inner wall of the middle part of the trocar 1 is a hollow structure; Drive rod hole A and drive rod hole B are arranged symmetrically; drive rod A 18 and drive rod B 2 are respectively pierced in drive rod perforation A and drive rod B 2; drive rod A 18 a...

Abstract

The invention discloses a laparoscope specimen fetching channel. The laparoscope specimen fetching channel comprises a puncture outfit and a conical core. The puncture outfit is of a tubular structureand is made of flexible materials, and the conical core can pass through the interior of the tube. The puncture outfit is hollow in the middle. Two groups of supporting rod are symmetrically arrangedin the puncture outfit. The upper end of each group of supporting rod is in transmission connection with a transmission rod. Curve-shaped metal rods are connected between the two groups of supportingrods in a crossed manner. The lower end of the metal rods are fixedly connected with the supporting rods through fixing screws, and the upper ends are vertically up and down movably connected with the supporting rods through movable screws. After a laparoscopic surgery specimen is amputated, the puncture outfit is placed, and the transmission rods drive the supporting rods to rotate, so movable screws on the supporting rods slide towards the lower end of the supporting rods, so that the inclination angle of metal rods is increased and puncture outfit wall flexible materials are expanded, making an abdominal wall puncture channel expanded, thereby being beneficial to taking out the surgery specimen. Meanwhile, abdominal wall muscles are not damaged, surgical incisions are not enlarged, thereby being beneficial to the recovery of patients. At the same time, operation time is saved and pains of patients are reduced.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a laparoscopic specimen fetching channel. Background technique [0002] As a minimally invasive technique, laparoscopic surgery is widely used in the field of surgery. Laparoscopic surgery establishes pneumoperitoneum, uses cold light source as illumination, and uses camera technology to display the surgical situation in the abdominal cavity on the display screen in real time, avoiding the shortcomings of large trauma and slow recovery caused by open surgery. However, since laparoscopic surgery is performed by punching holes in the abdominal wall and using instruments to perform surgery in the abdominal cavity, when the surgical specimen to be removed is too large, it is difficult to take it out through the operation hole on the abdominal wall. In most cases, the surgeon will make a long enough surgical incision on the abdominal wall to facilitate the removal of surgical specimens, which w...
