Description

Technical Field

[0001] This invention relates to medical devices, and more particularly to a transanal surgical assistance system that integrates a light source and anal dilation. Background Technology

[0002] Transanal surgery is a surgical technique performed through the natural orifice of the anus, primarily used to treat lesions in the rectum or anus. This type of surgery avoids open surgery or laparoscopic procedures, offering advantages such as minimal trauma and rapid recovery.

[0003] In transanal surgery, anal dilators can mechanically expand the anus and lower rectum, providing surgeons with ample operating space and direct vision. Through controllable and uniform expansion, they can avoid tearing of the anal sphincter or rectal mucosa caused by manual traction during surgery, reduce the risk of postoperative anal incontinence, and provide a stable transanal approach for instruments such as staplers and cutting and suturing devices in laparoscopic or robotic surgery, ensuring that the instruments can reach the lesion site smoothly.

[0004] Patent document CN220675974U discloses an anal dilator, which includes an anal dilator base, an anal dilator body fixedly installed at one end of the anal dilator base, a window opened on the surface of the anal dilator body, an arc-shaped opening fixedly installed at one end of the anal dilator body, a round hole opened on the surface of the arc-shaped opening, a sleeve fixedly installed at one end of the round hole, a bolt rotatably connected inside the sleeve, a connecting block fixedly installed at the upper end of the bolt, and a soft pad fixedly installed at the top of the connecting block.

[0005] However, conventional anal dilators cannot provide real-time observation of the intestinal wall during use, lack auxiliary support structures, and require manual holding by the surgeon throughout the procedure, which can easily lead to operator fatigue. Furthermore, the intestinal wall condition cannot be displayed in real time, affecting the efficiency and precision of the surgical procedure. Therefore, it is necessary to optimize the structure of the aforementioned anal dilator to overcome these shortcomings. Summary of the Invention
