Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a blood clot breaking device for a gastroenteroscopy. Background Art

[0002] The most direct and effective solution for gastrointestinal bleeding is to directly detect the cause and location of bleeding through gastroscopy and colonoscopy. After the cause of bleeding is determined, the corresponding endoscopic hemostasis treatment can achieve an immediate effect of stopping bleeding. However, patients with such active bleeding often have liquid blood and a large number of blood clots in the gastrointestinal cavity, resulting in unclear vision, inability to detect the cause and location of bleeding, and loss of surgical opportunity. In the current existing technology, the aperture of the traditional gastroscope and colonoscope suction tube is small, and the larger blood clots caused by gastrointestinal bleeding cannot be removed using the suction tube in the gastroscope and colonoscope.

[0003] The current external auxiliary devices all have defects to varying degrees. Most of them enter the gastrointestinal lumen through the endoscope suction channel. After the auxiliary fragmentation, the auxiliary device is still blocked in the suction channel, and the blood clot must be pulled out after the device is pulled out. When another blood clot is encountered, the device must be inserted again, resulting in low efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a blood clot breaking device for a gastroenteroscopy, which can follow the lens end of the endoscope to reach the required position and can continuously break up the blood clots, so that the broken blood clots can be discharged through the endoscope's own suction hole pipeline, which is easy to operate and improves efficiency.

[0007] Furthermore, in some embodiments of the present invention, the drive assembly includes a pull rope, and an installation channel is provided in the outer sleeve; the pull rope is wound around the outer wall of the rotating ring, one end of the pull rope is connected to the outer wall of the rotating ring, and the other end of the pull rope passes through the installation channel and is located outside the outer sleeve.

[0008] Furthermore, in some embodiments of the present invention, an annular receiving groove is provided on the outer side wall of the rotating ring, and the pull rope is wound in the receiving groove.

[0018] The embodiments of the present application are described in detail below in conjunction with the drawings in the embodiments of the present application.

[0019] Example

[0020] Please refer to Figure 1-Figure 2The present embodiment provides a blood clot breaking device for a gastroenteroscopy, comprising an outer sleeve 1, a rotating ring 2 is provided in the outer sleeve 1 for rotation, one end of the rotating ring 2 is a head end and is located outside the outer sleeve 1, and a plurality of cutting bristles 3 are provided at the head end of the rotating ring 2; the outer sleeve 1 is provided with a driving assembly for driving the rotating ring 2 to rotate along the outer sleeve 1, and the rotating ring 2 is connected to the driving assembly. The outer sleeve 1 of the present embodiment adopts an existing medical silicone tube, the length of the outer sleeve 1 is more than one meter, the rotating ring 2 is made of hard material, and the cutting bristles 3 are used to cut the blood clot during rotation to break the blood clot.

[0021] The driving assembly includes a pull rope 4, and an installation channel 5 is provided in the outer sleeve 1; the pull rope 4 is wound around the outer wall of the rotating ring 2, one end of the pull rope 4 is connected to the outer wall of the rotating ring 2, and the other end of the pull rope 4 passes through the installation channel 5 and is located outside the outer sleeve 1. Since the pull rope 4 is wound around the outer wall of the rotating ring 2, the rotating ring 2 can be rotated along the inner wall of the outer sleeve 1 by pulling the pull rope 4, which is convenient to operate.

[0022] When actually used, the crushing device provided by the present application is placed outside the gastroscope or colonoscope, that is, Figure 1 The outer sleeve 1 is shown to be sleeved on the outside of the endoscope tube 12, and the inner diameter of the rotating ring 2 is larger than the outer diameter of the endoscope tube 12, so the rotating ring 2 and the outer sleeve 1 as a whole can slide axially along the endoscope tube 12. During operation, the rotating ring 2 is located at the head end of the endoscope tube 12 and is placed into the patient's intestine from the patient's mouth along with the endoscope tube 12, and the other end of the outer sleeve 1 and the other end of the endoscope tube 12 are located outside the patient's body together, which is convenient for medical staff to operate.

[0023] During the process of inserting the rotating ring 2, Figure 1 As shown, the rotating ring 2 does not block the head end of the endoscope tube 12. At this time, the field of view of the camera of the endoscope tube 12 is exposed, which is convenient for medical staff to check. When the required position is reached and there is a blood clot that needs to be broken, the medical staff holds the end of the outer sleeve 1 outside the body and pushes the outer sleeve 1 inward. The outer sleeve 1 drives the rotating ring 2 to move forward a certain distance. The cutting bristles 3 at the head end of the rotating ring 2 move out of the head end of the endoscope tube 12. At this time, the medical staff pulls the pull rope 4 outward, and the pull rope 4 slides outward in the installation channel 5. In this way, the rotating ring 2 can be pulled by the pull rope 4 to rotate along the outer sleeve 1. At this time, the cutting bristles 3 rotate to break the blood clot. After the breaking is completed, stop pulling the pull rope 4, pull the outer sleeve 1 outward, and pull the rotating ring 2 to the position as shown in the figure. Figure 1 The position shown in the figure is to expose the visual field of the endoscope pipeline 12 cameras. Then the broken blood clot is discharged through the suction hole pipeline of the endoscope itself.

[0024] Thus, the blood clot breaking device for gastroenteroscopy provided by the present application can follow the lens end of the endoscope to the desired position, and can continuously break the blood clots, so that the broken blood clots can be discharged through the suction hole pipeline of the endoscope itself, which is convenient to operate and improves efficiency. The number of turns of the pull rope 4 wound around the outer wall of the rotating ring 2 can be sufficient, and the rotating ring 2 can be driven to rotate by pulling the pull rope 4 multiple times.

[0025] like Figure 1-Figure 2 As shown, in some embodiments, the outer side wall of the rotating ring 2 is provided with an annular receiving groove 6, and the draw cord 4 is wound in the receiving groove 6. The present invention facilitates the storage of the wound draw cord 4 through the receiving groove 6 by providing the receiving groove 6.

[0026] like Figure 1-Figure 2 As shown, in some embodiments, a winding motor 7 and a winding roller 8 arranged on the transmission shaft of the winding motor 7 are also included, and one end of the pull rope 4 away from the rotating ring 2 is connected to the winding roller 8.

[0027] The present invention is convenient to operate by setting a winding motor 7, which can start the winding motor 7 and drive the winding roller 8 to rotate to wind the pull rope 4. When in use, a corresponding control switch can be set to control the operation of the winding motor 7, and the winding motor 7 can be connected to a power supply for power supply.

[0028] like Figure 1-Figure 2 As shown, in some embodiments, a fixing ring 9 is fixedly provided on the inner side wall of the outer sleeve 1, and the rotating ring 2 is rotatably provided on the inner side wall of the fixing ring 9. A limiting flange 10 is provided on the inner side wall of the fixing ring 9, and an annular limiting groove 11 is provided on the outer side wall of the rotating ring 2, and the limiting flange 10 is slidably embedded in the limiting groove 11. The fixing ring 9 and the limiting flange 10 can be made of hard materials, so that the position of the rotating ring 2 can be limited by the limiting flange 10, which is convenient for the rotation of the rotating ring 2.
