[0001] This utility model relates to the field of medical assistive device technology, specifically to an auxiliary traction device for gastroscopy. Background Technology

[0002] Gastroscopy is a medical examination method, and also refers to the instrument used in this examination. It uses a thin, flexible tube inserted into the stomach, allowing doctors to directly observe lesions in the esophagus, stomach, and duodenum. Especially for minor lesions, gastroscopy can directly observe the true condition of the examined area.

[0003] During a gastroscopy, medical staff need to hold the endoscope head with one hand and insert the tube into the mouth with the other. During procedures such as symptom observation and foreign body removal, holding the endoscope tube for extended periods can cause arm pain and fatigue, affecting the stability of the medical staff's hands and increasing their workload. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary traction device for gastroscopy in order to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides an auxiliary traction device for gastroscopy, including an anterior plate. One end of the anterior plate is fixedly connected to a connecting strap, and the other end of the anterior plate is provided with an adhesive structure for fixing the end of the connecting strap. A tube hole is opened through the middle of the anterior plate, and a U-shaped groove is opened on the lower side of the tube hole. A tongue depressor is detachably installed in the U-shaped groove. The upper and lower sides of the inner sidewall of the anterior plate are fixedly connected to two tooth-supporting bite plates, and the two tooth-supporting bite plates are respectively located on the upper and lower sides of the tube hole. A crossbar is fixedly connected to the upper side of the outer sidewall of the anterior plate, and two linkage arms are rotatably connected to the end of the crossbar. The lower ends of the two linkage arms are fixedly connected to arc-shaped clamps, and a squeezing structure is provided on the upper side of the outer sidewall of the anterior plate for driving the two arc-shaped clamps to move closer to each other.

[0007] Preferably, the adhesive structure includes a through groove adapted to the connecting strip at the end of the front plate, the end of the connecting strip is fixedly connected to a hook and loop fastener, and the surface of the connecting strip is fixedly connected to a hook and loop fastener.

[0008] Preferably, the two side walls of the U-shaped groove are provided with inverted U-shaped grooves, and the two sides of the tongue depressor are fixedly connected with cylindrical protrusions that are adapted to the inverted U-shaped grooves. In addition, the two inverted U-shaped grooves are fixedly connected with locking strips that are adapted to engage with the cylindrical protrusions. The lower side wall of the front plate is provided with a support structure for driving the end of the tongue depressor to rotate.

[0009] Preferably, the support structure includes a nut fixedly connected to the outer wall of the front plate, wherein a bolt is threaded into the nut, and the end of the bolt abuts against the outer bottom surface of the tongue plate.

[0010] Preferably, the upper ends of both linkage arms are fixedly connected to rotating sleeves, and both rotating sleeves are rotatably connected to the crossbar, on which a limiting ring adapted to the rotating sleeve is fixedly connected.

[0011] Preferably, the extrusion structure includes an incline sleeve rotatably connected to the outer side wall of the front plate, and the side walls of the two linkage arms are provided with grooves that fit the incline sleeve.

[0012] Preferably, anti-slip pads are provided on the opposite surfaces of the two arc-shaped clamps.

[0013] The beneficial effects are:

[0014] The tongue depressor is rotated upward by the supporting structure, and the other end of the tongue depressor presses down on the tongue surface under the action of leverage. Then, the endoscope tube is inserted into the esophagus through the intubation hole. After the lens of the endoscope tube is moved to the lesion, the chamfered sleeve is pressed down. As the chamfered sleeve rotates downward, it squeezes the two linkage arms closer together. At this time, the two arc-shaped clamps hold the endoscope tube on both sides. During the insertion process, the clamps are fixed to avoid the arms being held up for a long time, which facilitates the subsequent stable operation of the medical staff's hands and improves the practicality.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] See Figures 1-4 As shown, this utility model provides an auxiliary traction device for gastroscopy, including an anterior plate 1. One end of the anterior plate 1 is fixedly connected to a connecting strap 2, and the other end of the anterior plate 1 is provided with an adhesive structure for fixing the end of the connecting strap 2. A tube hole 4 is opened through the middle of the anterior plate 1, and a U-shaped groove 5 is opened on the lower side of the tube hole 4. A tongue depressor 6 is detachably installed in the U-shaped groove 5. The upper and lower sides of the inner sidewall of the anterior plate 1 are fixedly connected to tooth-supporting bite plates 3, and the two tooth-supporting bite plates 3 are respectively located on the upper and lower sides of the tube hole 4. A crossbar 7 is fixedly connected to the upper side of the outer sidewall of the anterior plate 1. The end of the crossbar 7 is rotatably connected to two linkage arms 9. The lower ends of the two linkage arms 9 are fixedly connected to arc-shaped clamps 8, and a squeezing structure is provided on the upper side of the outer sidewall of the anterior plate 1 to drive the two arc-shaped clamps 8 to move closer to each other.

[0024] As an optional implementation, the adhesive structure includes a through-slot 19 that is adapted to the connecting strap 2 and is opened through the end of the anterior plate 1. The end of the connecting strap 2 is fixedly connected to the hook and loop fastener 20, and the surface of the connecting strap 2 is fixedly connected to the hook and loop fastener 21. When the upper and lower teeth bite on the two bite plates 3 respectively, the connecting strap 2 is wrapped around the back of the head, and its end is passed through the through-slot 19 and pulled back. At this time, the hook and loop fastener 20 and the hook and loop fastener 21 are bonded and fixed, thus completing the fixation of the anterior plate 1.

[0025] Reference Figure 2-3As shown, inverted U-shaped grooves 17 are provided in the middle of both side walls of the U-shaped groove 5. Cylindrical protrusions 16 adapted to the inverted U-shaped grooves 17 are fixedly connected to both sides of the tongue depressor 6. A retaining strip 18 adapted to engage with the cylindrical protrusion 16 is fixedly connected to each of the two inverted U-shaped grooves 17. A support structure for rotating the end of the tongue depressor 6 is provided below the outer side wall of the front plate 1. The support structure includes a nut 14 fixedly connected to the outer side wall of the front plate 1. A bolt 15 is threaded into the nut 14, and the end of the bolt 15 is connected to the tongue depressor 6. The outer bottom surface of the tongue depressor 6 is fitted and pressed by placing the two cylindrical protrusions 16 into the two inverted U-shaped grooves 17. The cylindrical protrusions 16 pass over the retaining strip 18 and are engaged in the inverted U-shaped grooves 17, preventing the tongue depressor 6 from falling off. At the same time, the tongue depressor 6 can rotate with the cylindrical protrusions 16 as the axis. When the bolt 15 is rotated, the end of the bolt 15 abuts against the bottom surface of the tongue depressor 6 and supports the end of the tongue depressor 6 to rotate upward. At this time, the end of the tongue depressor 6 located in the mouth presses down on the tongue under the action of leverage, completing the tongue depressor and facilitating the subsequent insertion of the cannula.

[0026] Specifically, the upper ends of the two linkage arms 9 are fixedly connected to rotating sleeves 10, and the two rotating sleeves 10 are rotatably connected to the crossbar 7. The crossbar 7 is fixedly connected to a limiting ring 11 that is adapted to the rotating sleeve 10. The limiting ring 11 can prevent the rotating sleeve 10 from shifting or shaking, while the rotating sleeve 10 can ensure the free rotation of the linkage arms 9.

[0027] Reference Figure 4 As shown, the compression structure includes a U-shaped sleeve 12 rotatably connected to the upper outer wall of the anterior plate 1, and grooves 13 adapted to the U-shaped sleeve 12 are provided on the side walls of the two linkage arms 9. When the U-shaped sleeve 12 rotates downward, it compresses the two linkage arms 9 closer to each other until the U-shaped sleeve 12 moves to the groove 13 and stops. At this time, under the friction of the external support force, the U-shaped sleeve 12 is prevented from shaking randomly. At the same time, two arc-shaped clamps 8 clamp the two sides of the endoscope tube. The diameter of the endoscope tube should be slightly larger than the distance between the two arc-shaped clamps 8 at this time to achieve a firm clamping effect. When it is necessary to loosen the two arc-shaped clamps 8, the U-shaped sleeve 12 can be pushed upward (e.g., Figure 2 (As shown).

[0028] Specifically, anti-slip pads are provided on the opposite surfaces of the two arc-shaped clamps 8, which can increase the friction between the arc-shaped clamps 8 and the surface of the endoscope tube after they come into contact, thereby improving the clamping and fixing effect.

[0029] The working principle of this utility model:

[0030] First, install the tongue depressor 6 in the U-shaped groove 5. Then, place the two dental support plates 3 in the patient's mouth, with the upper and lower teeth biting on the two dental support plates 3 respectively. Wrap the connecting strap 2 around the back of the head, pass its end through the strap groove 19 and pull it back to fix it through the adhesive structure. Then, the outer side of the tongue depressor 6 is rotated upward by the supporting structure. Under the leverage, the other end of the tongue depressor 6 presses down on the tongue surface. Then, the endoscope tube is inserted into the esophagus through the tube hole 4. After the end of the endoscope tube is moved to the lesion, the U-shaped sleeve 12 is pressed down. As the U-shaped sleeve 12 rotates downward, it squeezes the two linkage arms 9 closer to each other. At this time, the two arc-shaped clamps 8 hold the endoscope tube on both sides, completing the fixation of the endoscope tube.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
