Description

Technical Field

[0001] The utility model relates to the technical field of anal dilators, in particular to an adjustable anal dilator for gastrointestinal surgery. Background Art

[0002] The stomach and intestines generally refer to the stomach, small intestine, and large intestine of the digestive system. Almost all the nutrients needed by the human body need to pass through the stomach and intestines, and the stomach and intestines are also the most important organs for digestion. Gastrointestinal surgery is a department that treats and examines the stomach and intestines. When patients have gastrointestinal problems, in some cases, doctors need to dilate the patient's anus for easy examination during anorectal examinations or operations. When dilating the anus, an adjustable anal dilator for gastrointestinal surgery is needed.

[0003] However, since the adjustable anal dilator for gastrointestinal surgery in the prior art is manually adjusted to expand, the adjustment is time-consuming and labor-intensive, which affects the use efficiency of the adjustable anal dilator for gastrointestinal surgery. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable anal dilator for gastrointestinal surgery, comprising a base, a first fixed seat and a second fixed seat are respectively provided on both sides of the top of the base, a motor is installed on the first fixed seat, a driving end of the motor is fixed with one end of a first screw rod, one end of the first screw rod is fixedly connected to one end of the second screw rod, and the other end of the second screw rod is rotatably connected to one side of the second fixed seat through a bearing, a first sliding seat is threadedly installed on the first screw rod, and a second sliding seat is threadedly installed on the second screw rod, the first sliding seat and the second sliding seat are also slidably connected to the top of the base, a first expansion plate is vertically fixed on the top of the first sliding seat, and a second expansion plate is vertically fixed on the top of the second sliding seat, a first handle is provided at the bottom of the base, a control button is provided on the first handle, and the control button is electrically connected to the motor, support plates are provided on both sides of the bottom of the base, the distance between the first handle and the base is less than the distance between the support plate and the base, and a second handle is provided on one side of the base.

[0006] Preferably, a slide groove is provided on the top of the base, and the bottoms of the first sliding seat and the second sliding seat are slidably connected in the slide groove via corresponding pulleys.

[0007] Preferably, a battery is provided on a side of the base away from the second handle, and the battery is electrically connected to the motor.

[0008] Preferably, both the first expansion plate and the second expansion plate are arc-shaped plates, and both ends of the arc-shaped plates are rounded.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] This type of anal dilator uses a motor instead of manual drive, which saves time and effort to use and improves medical efficiency. During specific use, the motor drives the first screw and the second screw to rotate synchronously, so that the first sliding seat and the second sliding seat can move and adjust in relative or opposite directions under the rotation of the corresponding screws and the sliding action of the pulley, thereby driving the first expansion plate and the second expansion plate to expand outward or contract inward.

It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0016] Example: See Figure 1-3The utility model provides a technical solution: an adjustable anal dilator for gastrointestinal surgery, comprising a base 1, a first fixed seat 2 and a second fixed seat 3 are respectively arranged on both sides of the top of the base 1, a motor 4 is installed on the first fixed seat 2, a driving end of the motor 4 is fixed with one end of a first screw 5, one end of the first screw 5 is fixedly connected to one end of a second screw 6, and the other end of the second screw 6 is rotatably connected to one side of the second fixed seat 3 through a bearing 7, a first sliding seat 8 is threadedly installed on the first screw 5, and a second sliding seat 9 is threadedly installed on the second screw 6, and the first sliding seat 8 and the second sliding seat 9 are also slidably connected to the base 1 At the top, a first expansion plate 10 is vertically fixed to the top of the first sliding seat 8, and a second expansion plate 11 is vertically fixed to the top of the second sliding seat 9. A first handle 12 is provided at the bottom of the base 1, and a control button 13 is provided on the first handle 12. The control button 13 is electrically connected to the motor 4, and the start and close of the motor 4 is controlled by the control button 13. Support plates 14 are provided on both sides of the bottom of the base 1. The distance between the first handle 12 and the base 1 is smaller than the distance between the support plate 14 and the base 1, which is convenient for the stable placement of the anal dilator. A second handle 15 is provided on one side of the base 1, and holding the second handle 15 is convenient for moving the anal dilator.

[0017] In this embodiment, a slide groove 16 is provided on the top of the base 1, and the bottoms of the first sliding seat 8 and the second sliding seat 9 are slidably connected in the slide groove 16 through corresponding pulleys 17, so that the first sliding seat 8 and the second sliding seat 9 can slide along the slide groove 16.

[0018] In this embodiment, a battery 18 is provided on a side of the base 1 away from the second handle 15 . The battery 18 is electrically connected to the motor 4 , and the battery 18 provides power for the motor 4 .
