AI Technical Summary
Existing protective sleeves for robotic surgical arms are expensive, inconvenient to operate, prone to falling off and damage, pose an infection risk, and do not meet sterility requirements.
A disposable sterile protective sleeve for a robotic arm was designed, featuring a head fixing section, a telescopic section, and a protective section. It utilizes suction cup components and a metal plate for quick fixation, combined with Velcro components and a rigid protective shell for stability and protection, ensuring sterile installation.
It achieves simple operation, firm fixation, and aseptic installation, avoiding detachment and damage, meeting aseptic requirements, and improving the safety and efficiency of surgery.

Abstract
Claims
1. A disposable sterile protective sleeve for a robotic arm, characterized in that: The device includes a head fixing section (1), a telescopic section (2), and a protective section (3) arranged sequentially. The head fixing section (1) is provided with at least two sets of shaping rings (11), which are respectively located at the opening and tail end of the head fixing section (1). The inner wall of the head fixing section (1) between the two sets of shaping rings (11) is provided with several fixing modules (14). The fixing module (14) includes a suction cup assembly (141). The periphery of the head fixing section (1) is provided with a pocket body (13). The pocket cavity (12) in the pocket body (13) extends along the axial direction of the head fixing section (1) and extends at least to the location of the fixing module (14). The protective section (3) is provided with several Velcro assemblies (4) and several hard protective shells (5).
2. The single-use robotic manipulator sterile drape of claim 1, wherein: The fixing module (14) also includes a metal disk (142).
3. The single-use robotic manipulator sterile drape of claim 2, wherein: The fixing module (14) is provided in at least four groups and is evenly distributed in a ring shape along the inner wall of the head fixing section (1).
4. The single-use robotic manipulator sterile drape of claim 3, wherein: The pocket (13) is arranged in a ring shape.
5. The single-use robotic manipulator sterile drape of claim 4, wherein: The pocket body (13) is provided with a Velcro assembly (4) on its periphery.
6. Sterile drape for a robot arm of a single-use machine according to claim 4 or 5, characterized in that: The outer diameter of the shaping ring (11) set at the opening position of the head fixing section (1) is smaller than the outer diameter of the shaping ring (11) set at the tail end position of the head fixing section (1), and the bottom of the pocket body (13) is connected to the shaping ring (11) at the tail end position.
7. The single-use robotic manipulator sterile drape of any of claims 1-5, wherein: The rigid protective shell (5) is a cylindrical shell or a sheet shell installed on the protective section (3).
8. The disposable sterile protective sleeve for robotic arms according to any one of claims 1-5, characterized in that: The protection section (3) is provided with several marking areas (6).
9. The disposable sterile protective sleeve for robotic arms according to claim 8, characterized in that: The colors of the different identification areas (6) are different.
10. The single-use robotic manipulator sterile drape of any of claims 1-5, wherein: The protective section (3) is made of polyethylene film.
