Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.

As shown in fig. 1 to 4, the present utility model provides an elastic dilator for an endoscopic intestinal tract, comprising: a dilator body 1 and a rotation adjusting part 2. The dilator body 1 is adapted for mounting an endoscope therein. The rotation adjusting part 2 is adapted to rotate to clamp or unclamp the endoscope. The above components are described in detail below.

The whole expander body 1 is ellipsoidal, and the expander both ends all open, and the inside cavity of expander body 1, and the endoscope can be followed the opening part of expander body 1 one end and inserted in the expander body 1 to with expander body 1 relatively fixed, then medical personnel send into the expander body 1 into the health of disease, in order to observe and treat the disease.

It should be noted that, the connection of the dilator and the endoscope apparatus that is commonly used is comparatively inseparable, causes medical personnel to comparatively loaded down with trivial details during the installation endoscope apparatus to the dilator like this, also has the infirm condition of installation simultaneously, influences the treatment, and when the cleaning personnel washs simultaneously, also is difficult to pull down endoscope apparatus from the dilator. In the present embodiment, the above-described problem is solved by providing the rotation adjusting portion 2. Specifically, the rotation adjusting portion 2 is fixedly disposed at one end of the expander body 1, the rotation adjusting portion 2 is capable of rotating circumferentially, and the rotation adjusting portion 2 is capable of expanding and contracting radially. By the arrangement of the rotation adjusting part 2, the rotation adjusting part 2 clamps or unclamps the endoscope when the rotation adjusting part 2 rotates in the circumferential direction.

In order to achieve the above effect, the rotation adjusting portion 2 includes a fixed clamping assembly 21 and a rotation adjusting assembly 22. The fixed clamping assembly 21 is fixedly connected with the end part of the expander body 1, and the rotation adjusting assembly 22 is rotatably connected with the end part of the expander body 1. The endoscope is disposed sequentially through the stationary clamping assembly 21 and the rotational adjustment assembly 22. The fixed clamping assembly 21 is arranged on the inner side of the rotation adjusting assembly 22, the fixed clamping assembly 21 can stretch and retract along the radial direction, and the rotation adjusting assembly 22 is connected with the fixed clamping assembly 21. Specifically, the fixed clamping assembly 21 expands and contracts radially as the rotation adjustment assembly 22 rotates to clamp or unclamp the endoscope. The fixed clamping assembly 21 includes a fixed ring 211 and a plurality of sliding blocks 212. The side of the fixing ring 211 away from the expander body 1 is provided with a sliding groove 213, a plurality of sliding blocks 212 are circumferentially arranged in the sliding groove 213, and the sliding blocks 212 can slide along the radial direction. Through the arrangement, in the process of inserting the endoscope into the dilator body 1, the endoscope pushes each sliding block 212 to slide outwards in the radial direction until the endoscope passes through each sliding block 212, and after the endoscope passes through each sliding block 212, the sliding blocks 212 can clamp the endoscope from the circumferential direction so as to realize clamping and positioning of the endoscope.

In order to realize that the endoscope slides along the radial direction when the endoscope is inserted into the dilator body 1 along the sliding direction perpendicular to the sliding direction of the sliding block 212, the sliding block 212 is provided with an inclined surface 214 at the side far away from the dilator body 1. With the above arrangement, when the endoscope moves into the dilator body 1, the endoscope can be brought into contact with the inclined surface 214 of each slide block 212, and the slide blocks 212 can be pushed to slide in the radial direction by the inclined surfaces 214.

In order to enable the endoscope to squeeze out the sliding block 212, the sliding block 212 can obtain a clamping force on the endoscope, the fixed clamping assembly 21 further comprises a plurality of adjusting springs 215, one ends of the adjusting springs 215 are fixedly connected with the fixed ring 211, and the other ends of the adjusting springs 215 are fixedly connected with the sliding block 212. In this embodiment, one slider 212 is connected to three adjustment springs 215, and the adjustment springs 215 are compressed by the extrusion of the endoscope, so that the elastic force of the adjustment springs 215 provides a pressing force to the slider 212. After the endoscope is taken out from the dilator body 1, the slide block 212 can be driven to return by the adjusting spring 215.

To achieve the effect of an operator rotating the rotation adjustment assembly 22 to drive the slide block 212 to clamp or unclamp the endoscope, the rotation adjustment assembly 22 includes a rotation ring 221 and a plurality of guide grooves 222 formed on a side of the rotation ring 221 facing the slide block 212. The guide grooves 222 are continuously distributed along the circumferential direction of the rotating ring 221, and the guide posts 216 are abutted against the side walls of the guide grooves 222. A guide post 216 is vertically fixed to the side of the sliding block 212 away from the expander body 1. The end of the guide post 216 remote from the slider 212 abuts the bottom wall of the guide slot 222. The guide groove 222 includes a first inclined section 2221, a second inclined section 2222, and a horizontal section 2223, the horizontal section 2223 being disposed between the first inclined section 2221 and the second inclined section 2222, and one of the guide posts 216 being disposed between the first inclined section 2221 and the second inclined section 2222 of one of the guide grooves. With the above arrangement, when the operator rotates the rotary ring 221, the guide post 216 can slide along the first inclined section 2221 or the second inclined section 2222 with respect to the horizontal section 2223. Specifically, when the rotating ring 221 is rotated and the guide post 216 slides along the first inclined section 2221 or the second inclined section 2222 in a direction approaching the horizontal section 2223, the guide post 216 drives the sliding block 212 to slide radially outwards, so that the sliding block 212 releases the endoscope. Conversely, when the guide post 216 slides along the first inclined section 2221 or the second inclined section 2222 away from the horizontal section 2223, the guide post 216 drives the sliding block 212 to slide radially inward, so that the sliding block 212 clamps the endoscope. The guide column 216 is pushed by the general adjusting spring 215 to be located at the middle of the first inclined section 2221 or the second inclined section 2222, and the guide column 216 approaches the horizontal section 2223 when the operator rotates the rotating ring 221.

In order to achieve the effect of the relative rotation of the rotating ring 221 and the expander body 1, a T-shaped groove 11 is formed in the end portion of the expander body 1, a plurality of T-shaped blocks 223 are arranged on the inner side wall of the rotating ring 221, and the T-shaped blocks 223 are slidably arranged in the T-shaped groove 11. With the above arrangement, when the operator rotates the rotary ring 221, the T-shaped block 223 slides along the T-shaped groove 11, thereby ensuring the relative position of the rotary ring 221 and the expander body 1, and guiding the rotary ring 221 to rotate relative to the expander body 1.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
