Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to a flexible endoscope catheter structure which can be adjusted in multiple directions. Background Art

[0002] Endoscopic catheters currently used in clinical surgery are required to have a catheter head that can be bent within a certain range of angles in order to facilitate entry into diseased organs in the human body for large-scale observation and treatment, so as to drive the endoscope or corresponding surgical instruments to perform surgery in a direct image environment; among them, a hysteroscope is a medical device used to capture images of the inside of the uterus to assist doctors in disease diagnosis or surgical treatment.

[0003] After searching, the existing patent (Announcement No.: CN215227418U) discloses a hysteroscopic endoscope, including an endoscope catheter, a camera and a light source device, wherein the camera and the light source device are arranged in the front end of the endoscope catheter, and respectively face forward for shooting and lighting; a light adjustment structure is arranged in front of the light source device, and the light adjustment structure is used to process the illumination light emitted by the light source device, so that it propagates forward at a divergence angle that matches the field of view of the camera. The hysteroscopic endoscope optimizes the divergence angle of the illumination light, maximizes the utilization rate of the light, and the front end can be adjusted to any upper and lower bending angle or left and right bending angle, thereby increasing the observation range. It also comes with a flushing channel or an instrument channel for surgical instruments to enter the uterus, and can complete difficult surgical operations.

[0004] However, in the implementation of the relevant technology, the following problems were found: the current hysteroscopic endoscope usually directly adopts an endoscopic catheter, and the end of the endoscopic catheter is connected to a tube head through a movable tube so that the tube head can be adjusted in multiple directions. However, in the process of inserting the endoscopic catheter and the tube head into the uterine opening and introducing it into the uterine cavity, since the tube head is movably connected to the end of the endoscopic catheter, it is difficult to directly align the tube head with the uterine opening during insertion. Medical personnel need to hold the endoscopic catheter and the tube head with their hands all the time, which is very inconvenient to operate. Moreover, in the process of introducing the endoscopic catheter into the uterus, the outer wall of the endoscopic catheter and the inner wall of the uterine opening are always directly rubbed, which can easily cause discomfort or even injury to the patient.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7The utility model provides a technical solution: a flexible endoscope catheter structure that can be adjusted in multiple directions, including an endoscope catheter 1 and a tube head 3, an active tube 2 for adjusting the tube head 3 in multiple directions is arranged between the endoscope catheter 1 and the tube head 3, a camera 4 is fixedly connected inside the tube head 3, a slip ring 5 is slidably sleeved on the outer wall of the endoscope catheter 1, and the slip ring 5 is symmetrically distributed near the side of the tube head 3 and is respectively hinged with two first introduction pieces 6, one end of the two first introduction pieces 6 is respectively fixedly connected with a second introduction piece 7, the opposite sides of the two first introduction pieces 6 are respectively hinged with electric cylinders 8, and the opposite ends of the two electric cylinders 8 are respectively hinged on one side of the slip ring 5, and the two electric cylinders 8 are respectively electrically connected to the operating handle connected to the endoscope catheter 1 through wires.

[0031] First, in the initial state, the two pairs of first introduction pieces 6 and second introduction pieces 7 are in a merged state. Since the first introduction piece 6 is a semi-annular structure and the second introduction piece 7 is a semi-conical structure, the diameter of the circle formed by the ends of the two second introduction pieces 7 is smaller than the diameter of the tube head 3. The medical staff manually inserts the two merged second introduction pieces 7 into the patient's uterine opening until the two merged first introduction pieces 6 move into the uterine opening. At this time, the medical staff stops inserting the two first introduction pieces 7 inwards. Then, the two electric cylinders 8 are started by operating the handle. The two electric cylinders 8 respectively open the two first introduction pieces 6 outwards. The two first introduction pieces 6 respectively drive the two When the second introduction piece 7 is stretched outward, the two pairs of first introduction pieces 6 and second introduction pieces 7 will partially stretch the cervix. Then, since the endoscopic catheter 1 and the slip ring 5 are slidingly connected, the endoscopic catheter 1 can freely shuttle in the cervix, making it convenient to move the tube head 3 into the uterine cavity and to facilitate the camera 4 to observe the uterine cavity. After use, first pull out the endoscopic catheter 1 and the tube head 3 to the cervix, and then, by reversely adjusting the two electric cylinders 8, the two pairs of first introduction pieces 6 and second introduction pieces 7 will be driven to merge respectively. Finally, the two pairs of first introduction pieces 6 and second introduction pieces 7 can be directly pulled out. Therefore, by arranging two pairs of first introduction pieces 6 and second introduction pieces 7 between the endoscopic catheter 1 and the tube head 3, the two semi-conical second introduction pieces 7 can be more easily and conveniently inserted into the patient's uterine os, and, through the two electric cylinders 8, the two pairs of first introduction pieces 6 and second introduction pieces 7 can be conveniently opened to both sides, so that the patient's uterine os can be partially opened, which not only facilitates the insertion of the endoscopic catheter 1 and the tube head 3 into the uterine os and guides them into the uterine cavity, and facilitates the camera 4 in the tube head 3 to videotape and observe the inside of the uterine cavity, but also, because the uterine os is partially opened, it can prevent the endoscopic catheter 1 and the tube head 3 from generating excessive friction with the inner wall of the uterus, thereby causing discomfort or even injury to the patient.

[0032] See also Figure 1 , Figure 4 and Figure 7Two connecting plates 9 are symmetrically distributed and fixedly connected on the outer wall of the slip ring 5, and one end of the two connecting plates 9 is fixedly connected with a supporting plate 10. The connecting plate 9 is an L-shaped structure, and the horizontal section of the connecting plate 9 is fixedly connected to the supporting plate 10, and the vertical section of the connecting plate 9 is fixedly connected to the slip ring 5. When the two pairs of first introduction pieces 6 and the second introduction pieces 7 are inserted into the cervical ostium, the two supporting plates 10 will abut against the outside of the cervical ostium, which can not only support the slip ring 5 and the two pairs of first introduction pieces 6 and the second introduction pieces 7, and improve the stability of the two pairs of first introduction pieces 6 and the second introduction pieces 7 inserted into the cervical ostium, but also prevent the two pairs of first introduction pieces 6 and the second introduction pieces 7 from being accidentally completely inserted into the cervical ostium and difficult to pull out, thereby playing a protective effect.

[0033] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The side of the slip ring 5 away from the tube head 3 is fixedly connected with a sliding sleeve 11, and the sliding sleeve 11 is slidably sleeved on the outer wall of the endoscope catheter 1. The end of the sliding sleeve 11 away from the slip ring 5 is provided with a self-locking mechanism 12 for locking or unlocking the sliding sleeve 11. The self-locking mechanism 12 includes a rotating ring 121, which is rotatably connected to one end of the sliding sleeve 11, and the rotating ring 121 is slidably sleeved on the outer wall of the endoscope catheter 1. A plurality of clamping mechanisms are arranged in a circular distribution at equal intervals between the inner wall of the rotating ring 121 and the outer wall of the endoscope catheter 1. The clamping mechanism includes a clamping slot 122 and a groove 123. The clamping slot 122 is provided on the outer wall of the endoscopic catheter 1, and the groove 123 is provided on the inner wall of the rotating ring 121. A spring 124 is fixedly connected to the inner bottom of the groove 123. One end of the spring 124 is fixedly connected to a clamping block 125 clamped in the clamping slot 122. The clamping block 125 is an arc-shaped structure at one end close to the clamping slot 122. The clamping slot 122 is an arc-shaped groove, and the radius of the arc-shaped structure of the clamping block 125 is consistent with the radius of the arc-shaped inner wall of the clamping slot 122.

[0034] The two sides of the block 125 close to one end of the spring 124 are slidably set on the two sides of the inner wall of the groove 123 through a sliding mechanism. The sliding mechanism includes a slider 126 and a slide groove 127. The slider 126 is fixedly connected to one end of the block 125. The slide groove 127 is opened on one side of the inner wall of the groove 123, and one end of the slider 126 is slidably set in the slide groove 127. The slider 126 can only slide in the corresponding slide groove 127, so that the block 125 can only slide in the corresponding groove 123, and the block 125 will not fall out of the groove 123.

[0035] The working principle and use process of the utility model are as follows: first, in the initial state, the two pairs of first introduction pieces 6 and second introduction pieces 7 are in a merged state, and a plurality of card blocks 125 are respectively inserted into a plurality of card slots 122. At this time, the sliding sleeve 11 is locked on the endoscope catheter 1, and the slip ring 5 and the two pairs of first introduction pieces 6 and second introduction pieces 7 are also locked on the endoscope catheter 1. In this state, the medical staff can directly hold the sliding sleeve 11 by hand to insert the two pairs of first introduction pieces 6 and second introduction pieces 7 into the cervical cavity, avoiding the relative sliding between the cervical cavity 1 and the endoscopic catheter 1. The situation that causes the difficulty of insertion; when the two pairs of first introduction pieces 6 and second introduction pieces 7 are inserted into the cervical cavity and stretched, the medical staff rotates the rotating ring 121, and the rotating ring 121 drives the plurality of card blocks 125 to rotate circumferentially , the blocks 125 will be squeezed out of the corresponding slots 122 respectively, and the rotating ring 121 is stopped at this time, thereby unlocking the sliding sleeve 11, and the sliding ring 5, the two pairs of first guide pieces 6 and the second guide pieces 7 are also unlocked, and the endoscopic catheter 1 can slide freely in the sliding sleeve 11, the sliding ring 5, the two pairs of first guide pieces 6 and the second guide pieces 7, so that the endoscopic catheter 1 can freely shuttle in the cervical cavity; after use, the rotating ring 121 can be rotated again, and when several blocks 125 are driven to rotate to several slots 122, under the action of the spring 124, the blocks 125 will automatically snap into the corresponding slots 122 to complete the locking, so as to prevent the sliding sleeve 11, the sliding ring 5, the two pairs of first guide pieces 6 and the second guide piece 7 from slipping off the endoscopic catheter 1 when not in use. Therefore, by rotating the rotating ring 121, the block 125 is automatically inserted into the slot 122 under the action of the spring 124, so that the sleeve 11, the sliding ring 5, the two pairs of first introduction members 6 and the second introduction members 7 can be conveniently locked, thereby making it more convenient to insert the two pairs of first introduction members 6 and the second introduction members 7 into the cervical cavity, and avoiding the relative sliding between the endoscopic catheter 1 and the difficulty in insertion. When introducing the endoscopic catheter 1, it is only necessary to rotate the rotating ring 121 again so that the block 125 is squeezed out of the corresponding slot 122 to complete the unlocking and introduce the endoscopic catheter 1, thereby making it more convenient to introduce the endoscopic catheter 1 and the tube head 3.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
