Embodiment 1

[0017] Example 1, such as Figure 1~Figure 8 As shown, an auxiliary device for rectal surgery includes an auxiliary rod 1 and an adsorption device 16. The auxiliary rod 1 is a hollow cylindrical rod. The front part of the auxiliary rod 1 is provided with a front cylinder 2 and the rear end of the front cylinder 2 A sealing cover 3 is provided. The connection between the sealing cover 3 and the rear end of the front cylinder 2 is provided with threads. The sealing cover 1 and the front cylinder are connected by threads to facilitate disassembly and replacement of the battery. The sealing cover 3 is provided with a battery inside 4. A motor base 5 is provided on the inner side of the battery 4, a micro motor 6 is provided on the motor base 5, a fixed disk 7 is connected to the output shaft of the micro motor 6, and the output shaft is fixedly connected to the fixed disk, and the fixed disk 7 is provided with a rotating The head 8, the front of the rotating head 8 is hemispherical...

Embodiment 2

[0022] Example 2, such as Figure 1~Figure 8 As shown, in the present invention, the support rod and the lifting rod can be connected to adjust the upper and lower positions of the adsorption device, and the support rod can also be connected to the articulated robot, which can realize that the adsorption device has multiple degrees of freedom.

Embodiment 3

[0023] Example 3, such as Figure 1~Figure 8 As shown, in the present invention, a sliding varistor is provided on the transmission line, which can adjust the voltage, thereby changing the size of the generated electromagnetic, and then changing the suction force of the suction device to the auxiliary rod, so that it can be adapted to different surgical requirements.

Abstract

The invention belongs to a rectum operation assisting device, and the device comprises an auxiliary rod and an absorption device. The auxiliary rod can lift a rectum for a certain distance, so as to enable the rectum to be separated from the surrounding tissues by a certain gap, and achieve the better separation with an exposed tumor, thereby facilitating the operation. When the position of a U-shaped metal rod needs to be changed, only the T-shaped rod needs to move, so as to slide in a space between an external sliding way and an internal rod. The T-shaped rod drives a sliding plate to slide, and the sliding plate drives the U-shaped metal rod to slide, thereby changing the position of the U-shaped metal rod in the absorption device. The U-shaped metal rod can move 180 degrees in the external sliding way, thereby achieving the absorption of an assisting rod to different angles in the range of 180 degrees through the U-shaped metal rod, enabling the rectum to be fully exposed, and meeting the operation demands.

Description

Technical field [0001] The invention belongs to the technical field of medical instruments, and particularly relates to an auxiliary device for rectal surgery. Background technique [0002] Surgery is still one of the most important methods for the treatment of rectal cancer. However, due to the narrow pelvic cavity, the relationship between the rectum and the surrounding area is complicated. In the case of obese patients or large tumors, rectal cancer surgery may become more complicated and slightly careless. It may cause severe bleeding and side injuries, endangering the life of the patient. Surgical treatment of ultra-low rectal cancer is difficult to achieve anus-preserving treatment. One of the reasons is that the tumor is not fully exposed, the position of the rectum cannot be well controlled, and the tumor cannot be completely removed by freeing the tumor. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings in the prior ar...
