[0035] The current hysteroscope is generally a fixed instrument channel. During use, it generally has only one channel for the instrument to enter and exit. The overall operation is relatively simple, and there is a problem of poor flexibility in the medical operation of the instrument. In view of the above problems, the utility model provides a multi-channel hysteroscope, the sheath and the scope sheath are independently arranged. In actual use, the sheath can be used for the insertion of multiple instruments, and has the advantage of high flexibility in use. The specific scheme is as follows.
[0036] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model relates to a multi-channel hysteroscope 100, comprising a scope sheath 110, a cover sheath 120 and a soft cover 130, wherein the scope sheath 110 is connected to the endoscope assembly, the cover sheath 120 is parallel to the scope sheath 110 and fixedly connected to each other, and the two ends of the cover sheath 120 are an insertion end and an operating end respectively.
[0037] In addition, the opening of the soft sleeve 130 is inserted into the sheath 120 through the operating end, and the opening is sealed and fixedly connected to the inserting end; the soft sleeve 130 is provided with at least two connecting parts, which are located outside the operating end and are used to seal and connect the sealing plug, and the sealing plug is used for the instrument to be squeezed and sealed into the soft sleeve 130.
[0038] It should be noted that, refer to Figure 3 As shown, since the overall diameter of the sheath 120 is related to the size of the cervical opening, in this embodiment, the operable angle of the instrument is shown in the dotted line portion of the figure. In addition, the sealing rubber plug is a common connecting component of hysteroscopic instruments, which is used for the instrument to be squeezed and inserted during use. During the movement of the instrument, the sealing rubber plug can seal the insertion port of the instrument.
[0039] In this embodiment, the scope sheath 110 and the cover sheath 120 are a rigid connection structure as a whole. In actual use, the scope sheath 110 is connected and installed with the endoscope assembly. During the operation, the medical staff observes through the endoscope assembly and inserts the cover sheath 120 as a whole into the patient's uterine cavity.
[0040] Illustratively, when the device is used for medical operations, the installation of the sheath 110 and the endoscope assembly is completed first, and then the insertion end of the sheath 120 is inserted into the patient's uterine cavity through observation. At this time, the sheath 120 forms a cavity for the instrument to move around. In actual use, the instrument to be used is inserted into the soft sheath 130 through the sealing plug for surgical operation. In conjunction with the endoscope assembly of the sheath 110, the sheath 120 and the sheath 110 are independently arranged. In actual use, the sheath 120 can be used for the insertion of a variety of instruments, and has the advantage of high flexibility in use.
[0041] In one embodiment, it is more preferred that a drainage tube 133 is connected to the soft sleeve 130 , the drainage tube 133 is located outside the operating end, and a sealing plug is provided on the drainage tube 133 .
[0042] During use, by removing the sealing plug on the drainage tube 133, medical staff can discharge the fluid in the uterine cavity according to actual conditions to adjust the pressure inside the uterine cavity. When there is no need to discharge the fluid in the uterine cavity, install the sealing plug to seal the drainage tube 133 to prevent the fluid in the uterine cavity from leaking out.
[0043] In one embodiment, specifically, two connection parts are provided, namely a first connection part 131 and a second connection part 132 , and a connection port diameter of the first connection part 131 is larger than a connection port diameter of the second connection part 132 .
[0044] It should be noted that the connection port diameters of all connection parts are configured according to actual needs. In some operations, two instruments of different sizes are required. At this time, the first connection part 131 and the second connection part 132 can be used for instrument insertion. In the early design and manufacturing stage, connection parts with different connection port sizes can be configured according to actual conditions, or connection parts with the same connection port size can be configured. The specific details depend on actual needs and will not be elaborated here.
[0045] In one embodiment, it is preferable that the connection structure between the mirror sheath 110 and the cover sheath 120 is further refined, and the mirror sheath 110 is partially embedded in the inner wall of the cover sheath 120, wherein one end of the mirror sheath 110 is located outside the operating end for connection and installation of the endoscope assembly, and the other end of the mirror sheath 110 is inserted into the cover sheath 120 through the first mounting hole 121 on the operating end, and extends from the insertion end for the camera lens to take pictures.
[0046] This structural setting can optimize the installation structure of the device, and the part of the mirror sheath 110 that needs to enter and exit the uterine cavity is stored inside the inner wall of the uterine sheath 120, so as to improve the external smoothness of the sheath 120, avoid friction between the sheath 120 and the patient's body during movement, and protect the patient.
[0047] In one embodiment, a liquid inlet tube 123 is further provided on the sheath 120 , and the liquid outlet of the liquid inlet tube 123 is located at the insertion end, and the liquid inlet is located outside the operation end.
[0048] Illustratively, when the device is used for surgical operations, after the sheath 120 is inserted, when medical staff need to inject distending fluid into the uterine cavity to adjust the internal pressure of the uterine cavity, it can be injected into the uterine cavity through the liquid inlet tube 123, which also makes it convenient for medical staff to control the pressure inside the patient's uterine cavity, and has high practicality.
[0049] In this embodiment, the overall structure of the liquid inlet tube 123 can be passed through the inside of the soft cover 130 so as to be embedded in the inner wall of the sheath 120 , which is similar to the connection structure of the mirror sheath 110 .
[0050] Specifically, in this embodiment, the liquid inlet pipe 123 is embedded in the inner wall of the sheath 120, wherein the liquid inlet of the liquid inlet pipe 123 is located outside the operating end, and the liquid inlet is also provided with a sealing plug. The other end of the liquid inlet pipe 123 is inserted into the sheath 120 through the second mounting hole 122 on the operating end, and extends out from the insertion end.
[0051] It should be noted that the embedded structure setting of the liquid inlet tube 123 can simplify and hide the installation structure of the liquid inlet tube 123, so as to minimize the risk of interference with the overall structure of the liquid inlet tube 123. When medical staff operate the instrument through the software cover 130, the structure of the liquid inlet tube 123 is prevented from interfering with the operation of the medical staff, thereby optimizing the overall structure.
[0052] In one embodiment, specifically, the port formed by the insertion end is arranged flush. The port is provided with an inclined surface at a position corresponding to the mirror sheath 110, and the inclined surface is inclined toward the inner direction of the sheath 120. The inclined surface forms an inclined angle with the circumference of the sheath 120, and the angle of the inclined angle is 10 degrees to 30 degrees.
[0053] In this embodiment, the specific angle of the inclination is 15 degrees. In actual use, since the overall position of the inclined surface corresponds to the end of the mirror sheath 110, the camera of the endoscope assembly is located at the end, and the inclined surface can facilitate the camera to shoot, thereby expanding the shooting angle. At the same time, the inclined surface can also protect the camera when entering and exiting the uterine cavity.
[0054] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model also provides a specific implementation method:
[0055] When using the device for medical operation, the installation of the scope sheath 110 and the endoscope assembly is completed first, and then the insertion end of the sheath 120 is inserted into the patient's uterine cavity through observation. At this time, the sheath 120 forms a cavity for the instrument to be operated. When actually used, the instrument to be used is inserted into the soft sheath 130 through the sealing rubber plug for surgical operation;
[0056] After the sheath 120 is inserted, when the medical staff needs to inject uterine distension fluid into the uterine cavity to adjust the internal pressure of the uterine cavity, it can be injected into the uterine cavity through the liquid inlet tube 123, so that the medical staff can control the pressure inside the patient's uterine cavity;
[0057] During use, by removing the sealing plug on the drainage tube 133, medical staff can discharge the fluid in the uterine cavity according to actual conditions to adjust the pressure inside the uterine cavity. When there is no need to discharge the fluid in the uterine cavity, install the sealing plug to seal the drainage tube 133 to prevent the fluid in the uterine cavity from leaking.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
