Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary traction device for endoscopy. Background Technology

[0002] During endoscopic examinations and treatments in gastroenterology, it is often necessary to traction foreign bodies or tissues within the body. However, traditional endoscopic traction devices still have the following shortcomings: 1. Traditional endoscopic traction devices are difficult to adjust flexibly according to the different anatomical structures and foreign body locations of different patients. As a result, in actual operation, it is difficult for medical staff to deliver the traction component to the target position, increasing the difficulty and time cost of the operation; 2. Because foreign bodies may adhere to some fluids in the patient's body, they become very slippery and easily slip out of the clamps, causing secondary injury to the patient. Therefore, we have introduced an endoscopic traction device. Utility Model Content

[0003] The main objective of this invention is to provide an auxiliary traction device for endoscopy, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An auxiliary traction device for endoscopy includes an installation tube and a connecting plate. The upper end of the installation tube is threadedly connected to a control component. The middle of the front end of the connecting plate is fixedly connected to a fixing block. The upper end of the fixing block has a pre-reserved hole that passes through from top to bottom. The lower end of the connecting plate is fixedly connected to a traction component. The outer surface of the installation tube is provided with anti-slip texture.

[0006] The traction assembly includes a connecting block and a connecting spring. A circular hole is opened in the middle of the upper end of the connecting block. Movable plates are movably installed on the front inner wall and the rear inner wall of the connecting block through a rotating shaft. Connecting rods are movably installed on the outer sides of the two movable plates through a rotating shaft. Traction clamps are fixedly connected to the lower ends of the two connecting rods. Several anti-slip teeth are fixedly connected to the lower inner side of the two traction clamps.

[0007] Preferably, the connecting plate includes a plate body, with a through hole at the middle of the upper end of the plate body, and through grooves at the left and right sides of the upper end of the plate body.

[0008] By adopting the above technical solution, the grooves on the plate provide constraints and guidance for the movement of the connecting rod.

[0009] Preferably, the upper end of the connecting spring is fixedly connected to the lower end of the plate, and the lower end of the connecting spring is fixedly connected to the upper end of the connecting block.

[0010] By adopting the above technical solution: when the control component applies force through the movable rod, the connecting spring will evenly distribute the force to the connecting block, and then transmit it to the traction clamp through the movable plate and the connecting rod.

[0011] Preferably, the upper parts of the two connecting rods are respectively movably sleeved in the corresponding two sliding grooves, and the plurality of anti-slip teeth are distributed in pairs at equal distances.

[0012] By adopting the above technical solution: when the traction device is working, when the movable rod drives the connecting block and the movable plate to move, and then drives the connecting rod to move, the slide can ensure that the connecting rod moves along a specific trajectory, avoiding deviation or shaking during the movement.

[0013] Preferably, the control component includes a control screw, with a control knob fixedly connected to the upper end of the control screw, and a movable rod fixedly connected to the lower end of the control screw. The lower end of the control screw is threadedly connected to the upper end of the mounting tube.

[0014] By adopting the above technical solution, medical staff can easily drive the control screw to rotate by turning the control knob.

[0015] Preferably, the movable rod is movably sleeved in the movable hole and the lower part of the movable rod is movably sleeved in the circular hole, and the movable rod is located inside the connecting spring and has a gap with the inner wall surface of the connecting spring.

[0016] By adopting the above technical solution, when the control component drives the movable rod to move up and down, the movable hole and the round hole can restrict the movement trajectory of the movable rod, so that it can only move in a straight line along the axial direction, thus avoiding the movable rod from shaking or deviating during the movement.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, by controlling the threaded connection between the screw and the installation tube, the up and down movement of the movable rod can be easily achieved by simply turning the control knob, thereby driving the opening and closing of the traction clamp. This allows medical staff to flexibly adjust the position and state of the traction clamp according to the actual situation, better adapt to the internal environment and foreign body position of different patients, and greatly improve the flexibility and convenience of operation.

[0019] 2. In this utility model, the lower part of the inner side of the two traction clamps is provided with anti-slip teeth that are evenly distributed in pairs, which can provide greater friction when clamping foreign objects and ensure that the foreign objects are firmly clamped.

[0029] Please see Figure 1-5This utility model provides a technical solution:

[0030] An auxiliary traction device for endoscopy includes an installation tube 1 and a connecting plate 2. The upper end of the installation tube 1 is threadedly connected to a control component 3. The middle of the front end of the connecting plate 2 is fixedly connected to a fixing block 4. The upper end of the fixing block 4 has a pre-reserved hole 5 that passes through from top to bottom. The lower end of the connecting plate 2 is fixedly connected to a traction component 6. The outer surface of the installation tube 1 is provided with anti-slip texture 7.

[0031] The traction assembly 6 includes a connecting block 61 and a connecting spring 62. A circular hole 63 is opened in the middle of the upper end of the connecting block 61. Movable plates 64 are movably installed on the front inner wall and the rear inner wall of the connecting block 61 through a rotating shaft. Connecting rods 65 are movably installed on the outer sides of the two movable plates 64 through a rotating shaft. Traction clamps 66 are fixedly connected to the lower ends of the two connecting rods 65. Several anti-slip teeth 67 are fixedly connected to the lower part of the inner side of the two traction clamps 66.

[0032] In this embodiment, the connecting plate 2 includes a plate body 21, with a through-hole 22 in the middle of the upper end of the plate body 21, and through-grooves 23 in the left and right upper ends of the plate body 21; the upper end of the connecting spring 62 is fixedly connected to the lower end of the plate body 21, and the lower end of the connecting spring 62 is fixedly connected to the upper end of the connecting block 61; the upper parts of the two connecting rods 65 are respectively movably sleeved in the corresponding two grooves 23, and a number of anti-slip teeth 67 are distributed in pairs at equal distances; the control component 3 includes a control screw 31, with a control knob 32 fixedly connected to the upper end of the control screw 31, and a movable rod 33 fixedly connected to the lower end of the control screw 31, and the lower end of the control screw 31 is threadedly connected to the upper end of the mounting tube 1; the movable rod 33 is movably sleeved in the movable hole 22 and the lower part of the movable rod 33 is movably sleeved in the round hole 63, and the movable rod 33 is located in the connecting spring 62 and has a gap with the inner wall surface of the connecting spring 62.

[0033] It should be noted that this utility model is an auxiliary traction device for endoscopy. During use, the endoscope is carefully placed in the pre-drilled hole 5 at the top of the fixing block 4, and the position of the endoscope is adjusted to ensure that it is in a suitable operating position for easy traction operation. Then, the medical staff holds the installation tube 1, aligns the open traction clamp 66 with the foreign object to be clamped, and slowly rotates the control knob 32, which drives the control screw 31 to rotate on the installation tube 1. Since the control screw 31 is threadedly connected to the installation tube 1, when the control knob 32 is rotated, the control screw 31 rotates on the installation tube 1. 1 will move upward, thereby driving the movable rod 33 to move upward within the movable hole 22 and the round hole 63. At this time, the connecting spring 62 is contracted, and the two movable plates 64 rotate around the pivot, causing the two traction clamps 66 to close. The anti-slip teeth 67, which are evenly distributed on the lower part of the inner side of the traction clamps 66, tightly clamp the foreign object. After confirming that the foreign object is firmly clamped, the medical staff hold the installation tube 1 and, with the help of the good grip provided by the anti-slip texture 7, carefully and slowly remove the endoscope and the clamped foreign object from the body together. During the process, pay attention to maintaining stability and avoid the foreign object falling off.
