Description

Technical Field

[0001] The utility model relates to the technical field of colonoscopy detection, in particular to a digestive department colonoscopy detection anal dilation device. Background Art

[0002] A colonoscopy is a common medical examination method used to evaluate the health of the rectum and anal area. This examination is usually performed by a gastroenterologist or gastrointestinal specialist to detect and diagnose various digestive system problems such as tumors, polyps, inflammation, ulcers, etc. Through colonoscopy, the doctor can visually observe the internal conditions of the anus and rectum so that potential diseases can be discovered and treated in time.

[0003] The announcement number is CN215899622U. The Chinese patent discloses an anal dilation device for enteroscopic examination in the Department of Gastroenterology. It includes a sleeve, an expansion mechanism and a handle. The expansion mechanism includes an insertion flap and an opening and closing rod. The two insertion flaps are hinged at one end, and an opening and closing rod is provided next to the hinge on the same side of each insertion flap. When the two insertion flaps are closed, it is convenient to insert into the patient's anus. Manually pinching the two opening and closing rods can unfold the two insertion flaps, thereby gradually expanding the patient's anus and preventing the continuous friction of the patient's anus during the insertion of the colonoscope, which increases the patient's pain. When the colonoscope probe is inserted into the sleeve, the guide wheel drives the colonoscope probe to extend inward, realizing the automatic insertion of the colonoscope probe, which is conducive to reducing the burden on doctors.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings. In actual use, it is necessary to rotate the control lever to realize the opening and closing of the two insertion flaps to achieve the effect of dilating the anus. This manual operation method increases the workload of the doctor and is inconvenient for the doctor to use when the doctor needs to operate the colonoscope and the handheld device at the same time. Therefore, it is necessary to provide a gastroenterology colonoscopy detection anal dilation device to solve the above-mentioned technical problems. Utility Model Content

[0028] See also Figure 1-4 , an embodiment provided by the utility model:

[0029] A digestive system enteroscopic anal dilation device, comprising:

[0030] A sleeve 1, one end of the sleeve 1 is provided with symmetrically distributed insertion flaps 2, and the two insertion flaps 2 are fixedly installed with symmetrically distributed connecting plates 16 at one end close to the sleeve 1, and the insertion flaps 2 are hinged to the outer wall of one end of the sleeve 1 through the connecting plates 16, and a fixing block 4 corresponding to the position and number of the connecting plates 16 is fixedly installed on the outer wall of one end of the sleeve 1;

[0031] A return spring 3 is fixedly connected between the fixed block 4 and the corresponding connecting plate 16, a support plate 7 is fixedly installed on the outer wall of the sleeve 1, and mounting grooves 10 are opened on the upper and lower sides of one side of the support plate 7, and a winding frame 6 is rotatably installed inside the two mounting grooves 10;

[0032] A pull rope 5 is fixedly connected to both winding racks 6, and one end of the pull rope 5 is fixedly connected to the outer surface of the petal 2 at the corresponding position. A fixed cavity 12 is opened behind one side of the support plate 7, and a driving mechanism is arranged inside the fixed cavity 12.

[0033] A plurality of connecting rods 9 are fixedly mounted on the outer wall of the other end of the sleeve 1 , and an annular handle 8 is fixedly mounted on the sleeve 1 via the connecting rods 9 .

[0034] In one of the embodiments, a non-slip rubber coating is provided on the outer wall of the annular handle 8, which increases the friction when the doctor holds the device and improves the stability and reliability of the device during use.

[0035] In one of the preferred embodiments, the driving mechanism includes a worm 13, and the number of the worm 13 is two, the two worms 13 are rotatably installed on the top and bottom of the inner wall of the fixed cavity 12, and the opposite ends of the two worms 13 are fixedly installed with gears 14, and the two gears 14 are meshed with each other. A transmission shaft 17 is rotatably installed at the top and bottom of the fixed cavity 12, and one end of the transmission shaft 17 passes through one side of the inner wall of the fixed cavity 12 and extends to the interior of the positioning position mounting groove 10 and is fixedly connected to one end of the winding frame 6. Worm wheels 11 are fixedly installed on the outer walls of the two transmission shafts 17, and the worm wheels 11 are meshed with the corresponding worms 13. A motor 15 is fixedly installed on the rear side of the bottom of the support plate 7, and the driving end of the motor 15 passes through the bottom of the support plate 7 and extends to the interior of the fixed cavity 12 and is fixedly connected to the bottom end of a worm 13, thereby realizing the automatic opening and closing of the inserted flap 2.

[0036] In one of the embodiments, the pull rope 5 is made of nylon. The pull rope 5 made of nylon has the characteristics of wear resistance, corrosion resistance and high strength, making it suitable for long-term use and able to maintain stability during operation, which helps to improve the reliability and durability of the device.

[0037] In one of the preferred embodiments, a control button is installed on the outer surface of the sleeve 1 on one side of the annular handle 8, and the control button is electrically connected to the motor 15, which improves the convenience and flexibility of operation and makes the doctor more convenient and efficient during operation.

[0038] The working principle of the utility model is as follows: the electrical components appearing in the present application are all connected to an external power source when in use, and the parts not involved in the device are the same as the prior art or can be implemented by the prior art. When in use, the doctor inserts the end of the insertion flap 2 with a smaller diameter into the patient's anus, and then controls the motor 15 to start working. The driving end of the motor 15 drives the worm 13 below to rotate, and the gear 14 follows the worm 13 to rotate. Through the meshing of the two gears 14, the two worms 13 rotate synchronously in opposite directions. Through the meshing of the worm 13 and the worm wheel 11, the worm wheel 11 drives the transmission shaft 17 to rotate, and the rotation of the transmission shaft 17 drives the winding rack 6 to rotate. At this time, the two winding racks 6 rotate in opposite directions and reel in the pull rope 5 at the same time. In the process of reeling in the pull rope 5, the two insertion flaps 2 will be driven to open, and the insertion flap 2 will be connected to the connecting rod 5 during the opening process. The connecting plate 16 squeezes the reset spring 3, and as the angle between the two insertion flaps 2 becomes larger and larger, the expansion effect on the patient's anus is achieved. At this time, the doctor can insert the colonoscopy probe into the interior of the sleeve 1 and then from the interior of the sleeve 1 into the space between the two insertion flaps 2 and finally into the patient's body for examination. After completing the examination, the colonoscope is withdrawn, and the two winding frames 6 are controlled to rotate relative to each other to remove the pull rope 5 wrapped around the winding frames 6. At this time, the two insertion flaps 2 will be closed under the elastic action of the reset spring 3, and then the device is taken out. During use of the device, the opening and closing of the insertion flap 2 is completed by mechanical drive. In actual operation, the doctor only needs to control the opening and closing of the insertion flap 2 through the control button to easily achieve the expansion effect of the patient's anus. There is no need to manually adjust the mechanical structure, which reduces the doctor's workload and improves the convenience of use for the doctor.

[0039] When using the device, the doctor can hold the device by the ring handle 8. Since the ring handle 8 is designed to be a ring structure, it will not limit the doctor's holding angle, making it convenient for the doctor to use the device flexibly. In addition, the anti-slip rubber wrapping layer on the outer wall of the ring handle 8 increases the friction when the doctor holds the device, thereby improving the stability and reliability of the device during use.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
