Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a novel gastroscope that can be adjusted with multiple instruments. Background Technology

[0002] Gastroscopy has advantages such as short examination time, high diagnostic rate, good efficacy, and high safety, making it the most commonly used examination method for upper gastrointestinal diseases. It can also assist in various endoscopic treatments, such as electrocoagulation resection of gastric and duodenal polyps, endoscopic hemostasis for upper gastrointestinal bleeding, and endoscopic treatment of early-stage upper gastrointestinal cancers.

[0003] When gastroscopy is used for diagnostic procedures, it is mainly used to observe the mucosa and lesion sites of organs such as the esophagus, stomach, and duodenum. It is used to determine whether there are diseases such as inflammation, ulcers, polyps, tumors, esophageal and gastric varices, and digestive tract stenosis. Generally, a preliminary judgment can be made after the examination. For tumors and polyps, further diagnosis is required by combining pathological tissue biopsy. For submucosal lesions, endoscopic ultrasound or chest, abdominal and pelvic CT may be needed to determine the nature of the lesion.

[0004] During current examinations, doctors need to collect multiple samples when using gastroscopy to obtain biopsy samples, switching between surgical instruments during the procedure. For some special diseases, it is inconvenient to obtain samples during the examination, requiring surgical sampling. Summary of the Invention

[0026] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of the present invention should be considered within the protection scope of the present invention. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the protection scope of the present invention.

[0027] See Figures 1 to 4As shown, a novel gastroscope with adjustable multi-instrument features a tube body 11. The tube body 11 has a through-hole 12. The tube body 11 is a common flexible tube that can bend and move freely. Therefore, the internal instruments are controlled by traction cables. Several movable rings 13 are arrayed on the inner wall of the inner wall 12. Positioning sleeves 14 are slidably installed on the inner wall of the movable rings 13. The number of positioning sleeves 14 is the same as the number of instruments inside the tube body 11. The traction cables of the control instruments pass through the positioning sleeves 14 to prevent the traction cables from tangling during switching.

[0028] The upper end of the tube 11 is connected to an external control device. The upper end of the traction rope extends out of the inner cavity 12 and is connected to the external control device. The lower end of the traction rope is connected to the instrument for operation.

[0029] The lower end of the inner cavity 12 is provided with an arc-shaped block 31. The arc-shaped block 31 does not completely seal the lower opening of the inner cavity 12, allowing instruments to extend from the edge of the arc-shaped block 31. A camera 33 and a trachea 34 for aspiration and drainage are fixedly connected to the arc-shaped block 31 for gastroscopy detection.

[0030] An adjustment device is provided inside the inner cavity 12. The adjustment device is connected to the arc-shaped block 31. Several instruments to be used are connected to the adjustment device. In this embodiment, there are three instruments. The adjustment device includes an upper turntable 46 and a base plate 41. A positioning shaft 44 is fixedly connected to the arc-shaped block 31. A rotating tube 45 is rotatably connected to the positioning shaft 44. The base plate 41 and the rotating tube 45 are fixedly connected. The upper turntable 46 and the rotating tube 45 are slidably connected vertically. The base plate 41 has several through holes 43 for instruments to pass through. The upper turntable 46 has several connecting holes 52 for connecting instruments. The upper ends of the rotating tube 45 and the positioning shaft 44 are provided with a switching structure for rotating the upper turntable 46 and the base plate 41. When it is necessary to switch instruments, the upper turntable 46 slides upward, and the switching structure drives the rotating tube 45 to rotate. When it is necessary to use an instrument, the upper turntable 46 and the base plate 41 are close together, and the instrument extends out from one side of the arc-shaped block 31.

[0031] The switching structure includes a connecting pipe 451, which is slidably connected to the rotating pipe 45. The connecting pipe 451 moves synchronously with the upper turntable 46. The upper end face of the connecting pipe 451 is fixedly connected to the upper end face of the upper turntable 46. The end face of the connecting pipe 451 is provided with several guide grooves 49. The upper end of the positioning shaft 44 is fixedly connected to a fixing cover 47, and the lower end face of the fixing cover 47 is fixedly connected to several positioning blocks 48. When switching instruments, the positioning blocks 48 abut against the guide grooves 49. The side walls of the positioning blocks 48 and the edges of the guide grooves 49 are chamfered to facilitate contact and sliding.

[0032] A connecting groove 51 extending upwards is connected to the side wall of the connecting hole 52. A connecting plate 53 is slidably installed on the side wall of the connecting groove 51. A sleeve 54 for connecting instruments is provided on the connecting plate 53. The sleeve 54 extends into the connecting hole 52 and extends vertically through the connecting plate 53. At the same time, a rubber block 56 is connected to the lower end of the sleeve 54. Both the sleeve 54 and the rubber block 56 are connected to instruments, thereby controlling the movement of the instruments.

[0033] A plurality of return springs 42 are provided between the chassis 41 and the upper turntable 46. The return springs 42 are located between the connecting hole 52 and the through hole 43. The through hole 43 and the connecting hole 52 correspond one-to-one. The instrument passes through the middle of the return spring 42 without affecting its use.

[0034] A slider 55 is slidably installed inside the side wall of the connecting groove 51. The slider 55 slides horizontally and is inserted horizontally into the inner wall of the connecting groove 51. The slider 55 is used to restrict the vertical movement of the connecting plate 53. When the instrument needs to extend out of the inner cavity 12, the connecting plate 53 and the connecting groove 51 do not separate. When the return spring 42 drives the upper turntable 46 to move, the upper turntable 46 extends the instrument through the connecting plate 53. The remaining instruments in the inner cavity 12 will have their lower ends abutting against the arc-shaped block 31, causing the connecting plate 53 to move upward relative to it, thereby pushing the slider 55. The connecting plate 53 and the upper turntable 46 will separate without affecting the instrument. The upper end surface of the arc-shaped block 31 is provided with a receiving groove 32 for positioning the instrument. The end face of the slider 55 is arc-shaped for easy movement.

[0035] The inner cavity 12 is equipped with a traction device for controlling the instrument. The traction device includes a traction rope 15, which passes through the entire inner cavity 12. The lower end of the traction rope 15 is fixedly connected to the upper turntable 46. The lower end of the traction rope 15 is forked and connected to the upper turntable 46 around the rotating tube 45. Pulling it upward will drive the instrument back to the inner cavity 12, and at the same time, the upper end of the connecting tube 451 will contact the fixed cover 47, thereby realizing the rotation of the rotating tube 45 and the switching of the instrument. At this time, the connecting plate 53 can also be reconnected to the upper turntable 46 to realize movement. After releasing the traction rope 15, the switched instrument can be released by the return spring 27 to ensure normal operation.

[0036] The upper end of the tube body 11 is connected to a movable cover 23. A movable block 26 is slidably installed on the movable cover 23. The lower end of the movable block 26 is fixedly connected to the traction rope 15. A handle 21 is fixedly connected to the upper end of the movable block 26, and the movement of the traction rope 15 is controlled by the handle 21.

[0037] The movable block 26 passes through the movable cover 23. A connecting spring 27 is sleeved on the lower side of the movable block 26 and the movable cover 23. One end of the connecting spring 27 is fixedly connected to the movable block 26, and the other end of the connecting spring 27 is fixedly connected to the end wall of the movable cover 23.

[0038] The upper end of the tube 11 is detachably connected to a mounting cover 22. The mounting cover 22 is provided with a through-hole slanted hole 25. The circumference of the movable cover 23 is connected to a connecting ring 24 via an extension rod. The connecting ring 24 and the inner wall of the slanted hole 25 are rotatably connected, leaving a certain gap between the movable cover 23 and the mounting cover 22. At this time, the traction rope of the control device can pass through the gap, thereby connecting to an external control device. The traction rope will be displaced due to the switching of the device, and the movable cover 23 can move accordingly.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
