Abstract

This creation is an improvement of the positioning and anti-slip structure of the endoscope handle. The main design is to install an innovative anti-slip structure inside the handle of the endoscope. The structure is provided with a convex rod on each side of the axis of the runner. Below the rods, there is a Y-shaped rod with a spring at the lower end, and an arc-shaped fixing plate is arranged above the convex rod. The spring provides upward elasticity to make the convex rod upward and close to the brake inside the fixed plate Film, in order to achieve a stable position of the runner, thereby effectively positioning the steel wire, and controlling the bending angle of the catheter, resulting in practical progress.

Description

Improved positioning and anti-slip structure for endoscope handle

This creation is an improvement of the positioning and anti-slip structure of the endoscope handle. The main design is to provide an innovative anti-slip structure inside the handle of the endoscope to achieve a stable position of the wheel, thereby effectively positioning the wire and controlling the bending angle of the catheter .

The design of the endoscope mainly uses a very small diameter catheter to facilitate easy extension into the human body to provide inspection or treatment. The lens module provided at the outer end of the catheter is used to capture the state of the body and transmit the image to the outside. Allow medical personnel to observe in order to achieve the purpose of diagnosis and treatment. During the implementation, after the catheter is inserted into the human body, in order to obtain a comprehensive observation, the bending angle of the tail end of the catheter must be adjusted. It is known to fix the wire end of the catheter to the rotating wheel inside the handle and use the knob outside the handle to turn. The revolving wheel rotates to pull the wire to change the bending angle of the end of the catheter. Because the catheter will produce a resilience when it is bent, users often need to keep their fingers pressed on the knob, which causes inconvenience in use. If you accidentally release your hand, the catheter tail will rebound and cause injury, so it is known The design needs to be improved.

This creation is an improvement of the positioning and anti-slip structure of the endoscope handle. The main design is to install an innovative anti-slip structure inside the handle of the endoscope. The structure is provided with a convex rod on each side of the axis of the runner. Below the rod, there is a Y-shaped rod with a spring on the lower end. Above it is an arc-shaped fixed plate. The spring provides upward elastic force to make the convex rod upward and cling to the brake pad inside the fixed plate to achieve a stable position of the wheel, thereby effectively positioning the steel wire and controlling the bending angle of the catheter. Those who have achieved practical progress.

This creation mainly provides an improvement of the positioning and anti-slip structure of the handle of the endoscope. In this embodiment, only the improved structure of the creation, that is, the structure of the handle part is described, please refer to the first to third figures. The characteristic structure includes a convex rod (11) on each side of the axis of the runner (1), a Y-shaped rod (2) is provided below the convex rod (11), and the Y-shaped rod (2) A spring (21) is sleeved on the lower end upright part, and an arc-shaped fixing plate (3) is arranged above the convex rod (11). A brake pad is combined on the inner side of the arc-shaped fixing plate (3). 31) When in use, the aforementioned spring (21) can provide a continuous upward elastic force to make the Y-shaped rod upward, and the Y-shaped rod (2) is used to push the top convex rod (11) upward and cling to the arc Brake pads (31) inside the fixing plate (3). At this time, the runner (1) receives the frictional force between the convex rod (11) and the brake pad (31) to form a stable positioning effect, therefore, the steel wire (4) coupled to the runner (1) is also fixed It does not move, but can achieve the effect of controlling the positioning of the end of the catheter.

When changing the angle of the catheter, simply press down the cover (5) located above the runner (1), so that the runner (1) and the convex rod (11) are downward, and the convex rod (11) is disengaged The friction of the brake pad (31) can easily turn the cover (5), and the rotation angle of the interlocking wheel (1), that is, the position of the wire (4), To obtain the purpose of changing the angle of the end of the catheter.

Claims (2)

An improved positioning and anti-slip structure for the handle of an endoscope includes a handle and a catheter. A rotary wheel combined with a wire end is provided in the handle. The characteristic structure includes a convex rod on each side of the axis of the rotary wheel. Below the rod, there is a Y-shaped rod, and a spring is sleeved on the lower end of the Y-shaped rod, and an arc-shaped fixing plate is arranged above the convex rod. For the brake pads, the above-mentioned spring provides a continuous upward elastic force to make the Y-shaped rod upward, and push the convex rod upward, so that the convex rod is close to the brake pad inside the arc-shaped fixed plate. The positioning and anti-slip structure of the handle of the endoscope as described in item 1 of the scope of the patent application is improved, in which the upper part of the runner is provided with a cover body, which can make the runner and its protruding rod downward and detach from The contact of the brake pads forms a state where the runner can easily rotate.
