Rotatable Arm Rest Seat for Laser Precision in Patient Cavity Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection devices for patient cavities, such as anoscopes and proctoscopes, face challenges in achieving high precision with surgical instruments like lasers, as they lack a suitable resting point for the laser head without obstructing the operator's view or reducing the field of view.
Innovation Solution
The device includes a dilator body with a handle and a rotatable arm that can move between an operative position to support a laser head and a rest position, allowing for flexible use without obstructing the operator's view. The arm is equipped with a rest seat for the laser head and is designed to be activated and deactivated to facilitate precise laser use and clear access when not needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed laser head is fully supported by the operator during surgical procedures, then high precision can be achieved, but it becomes difficult to maintain precision and operator fatigue increases
Solution Approach 1:
The patent introduces an intermediary support structure (the arm with rest seat) between the operator and the laser head. This arm is mounted on the dilator body and provides a rest seat that supports the laser head during surgical procedures, allowing the operator to maintain precision without fully bearing the weight and burden of supporting the laser head manually.
2Measurement precision
If a rest seat for the laser head is added to the dilator body, then precision is improved, but it may obstruct the operator's view or interfere with the surgical procedure
Solution Approach 1:
The patent implements a dynamic arm structure that can rotate and be positioned in different configurations. The arm mounted on the proximal portion of the dilator body can be adjusted to provide the rest seat for the laser head in positions that do not obstruct the operator's view through the distal portion, allowing the structure to adapt to different surgical needs while maintaining precision.
3Measurement precision
If the arm is positioned in the operative position to support the laser head, then precision is improved, but it reduces the space available for the operator to manoeuvre when the laser is not required
Solution Approach 1:
The rotatable arm design allows it to be positioned in an operative configuration when laser precision is needed, and then moved to a rest position when the laser is not required. This dynamic repositioning capability ensures that the arm provides support when needed but does not permanently occupy space that would be useful for operator maneuvering during other phases of the surgical procedure.

AI summary
A device for inspecting a cavity of a patient that includes a dilator body, extending along a longitudinal axis between a distal end and a proximal end, and a handle, applied or fixed to the proximal end of the dilator body. The device has a distal portion having a substantially tubular shape and a proximal portion extending from the distal portion in a diverging fashion, wherein the distal portion defines a zone of dilation of an internal cavity of a patient and delimits an internal volume accessible from a rear access opening made on the proximal portion. The distal portion of the dilator body has at least one front opening to enable access to the patient's mucosa or tissue from said internal volume. The device further has an arm mounted on the proximal portion and rotatable according to a main direction of movement relative to said proximal portion.
