Abstract
Description
Technical Field
[0001] This utility model relates to the field of gynecological instrument technology, specifically a dual-instrument channel hysteroscope. Background Technology
[0002] Hysteroscopy is a fiber optic endoscope used for examination and treatment within the uterine cavity. When using hysteroscopy to examine a patient's uterus, the hysteroscope is usually inserted into the uterus for observation. Once a lesion is found, a treatment instrument is inserted into the patient's body through the instrument operation port in the hysteroscope to treat the lesion.
[0003] However, traditional hysteroscopic instruments usually only have one access channel. When multiple instruments need to be used, the previous instrument must be removed and another instrument must be inserted. This makes it impossible to use two instruments together and the constant switching affects efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a dual-instrument-channel hysteroscope to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-instrument channel hysteroscope, comprising a first semi-protective tube and a second semi-protective tube, and further comprising,
[0006] A semi-scope tube, wherein a semi-limiting ring is fixedly connected to the outer edge of the semi-scope tube, and a semi-infusion tube is fixedly connected to the side of the semi-limiting ring away from the semi-scope tube. A semi-limiting ring is fixedly connected to the inner edge of the inner wall of both the semi-protective tube 1 and the semi-protective tube 2, and the inner wall of the semi-limiting ring 2 is fixedly connected to the side of the semi-infusion tube away from the semi-scope tube.
[0007] The instrument tube consists of two tubes symmetrically distributed between the first semi-protective tube, the second semi-protective tube, and the semi-scope tube. The outer wall of the instrument tube is slidably connected to the outer wall of the semi-scope tube and the inner walls of the first and second semi-protective tubes. The side opening of the instrument tube is slidably connected to the sides of the first and second semi-limiting rings to limit the range of movement.
[0008] Preferably, threaded holes 1 are provided on both sides of the surface of the second semi-protective cylinder, and threaded holes 2 are provided on both sides of the surface of the first semi-protective cylinder. The first semi-protective cylinder and the second semi-protective cylinder fit together and the openings of the first threaded holes correspond to the openings of the second threaded holes. Screws are threadedly connected to the inner walls of the first threaded holes and the second threaded holes.
[0009] Preferably, the inner wall of the instrument tube is threaded on one side and threaded to a threaded tube. An operating ring is fixedly connected to the side of the threaded tube away from the instrument tube. An operating rod is fixedly connected to the side of the operating ring away from the threaded tube. An annular anti-slip pad is fixedly connected to the side of the operating ring. The side of the annular anti-slip pad away from the operating ring is in contact with the side of the first and second semi-limiting rings.
[0010] Preferably, a hysteroscope is slidably connected through the inner wall of the semi-endoscopic tube, and a limiting ring is fixedly sleeved on the surface of the hysteroscope, with one side of the limiting ring fitting against the side of the semi-endoscopic tube.
[0011] Preferably, an infusion tube is slidably connected through the inner wall of the semi-infusion cylinder, and a limiting ring II is fixedly sleeved on the surface of the infusion tube, with one side of the limiting ring II fitting against the side of the semi-infusion cylinder.
[0012] Preferably, a handle is fixedly connected to the outer side of both the first and second semi-protective cylinders.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention, by setting up an instrument tube, allows two instruments to be inserted into the instrument tube through the operating ring and threaded tube when needed, with the instrument tip reaching the lesion. The instrument tube then moves along the gap between the first and second semi-protective tubes and the semi-endoscope tube, thereby changing the position of the instrument tip, making operation and adjustment easier. Both instruments can be operated simultaneously, facilitating coordination and reducing the inconvenience of changing instruments. This solves the problem that traditional hysteroscopic instruments mostly have only one operating channel, requiring the removal of one instrument before inserting another when multiple instruments are needed, making it impossible to coordinate the operation of two instruments and reducing efficiency due to frequent switching.
[0015] This invention features a threaded tube and an annular anti-slip pad. By gripping the operating rod and rotating the operating ring and threaded tube, the annular anti-slip pad disengages from the sides of the first and second semi-limiting rings, allowing the instrument cylinder to be moved. After determining the operating position, rotating the operating ring and threaded tube presses the annular anti-slip pad against the sides of the first and second semi-limiting rings, thus fixing the position of the instrument cylinder. The invention allows for switching between fixed and movable modes, facilitating different operations. Attached Figure Description

[0022] Please see Figures 1-4 This utility model provides a technical solution: a dual-instrument channel hysteroscope, including a semi-protective tube 1 and a semi-protective tube 2 7, and further comprising,
[0023] The semi-scope tube 2 has a semi-limiting ring 3 fixedly connected to the outer edge of the semi-scope tube 2. The semi-infusion tube 4 is fixedly connected to the side of the semi-limiting ring 3 away from the semi-scope tube 2. The inner wall edges of the semi-protective tube 1 and the semi-protective tube 2 7 are both fixedly connected to the semi-limiting ring 5. The inner wall of the semi-limiting ring 5 is fixedly connected to the side of the semi-infusion tube 4 away from the semi-scope tube 2.
[0024] Instrument cylinder 6, there are two instrument cylinders 6 and they are symmetrically distributed between semi-protective cylinder 1, semi-protective cylinder 2 and semi-scope cylinder 2. The outer wall of instrument cylinder 6 is slidably connected to the outer wall of semi-scope cylinder 2 and the inner wall of semi-protective cylinder 1 and semi-protective cylinder 2. The side opening of instrument cylinder 6 is slidably connected to the side of semi-limiting ring 3 and semi-limiting ring 2, which is used to limit the range of movement.
[0025] Both sides of the surface of the second semi-protective cylinder 7 are provided with threaded holes 8, and both sides of the surface of the first semi-protective cylinder 1 are provided with threaded holes 9. The first semi-protective cylinder 1 and the second semi-protective cylinder 7 fit together and the openings of the first threaded holes 8 and 9 correspond to each other. The inner walls of the first threaded holes 8 and 9 are connected with screws 10, which are used to merge the first semi-protective cylinder 1 and the second semi-protective cylinder 7 together and can be disassembled for easy cleaning of the inside.
[0026] The inner wall of the instrument cylinder 6 is threaded on one side and threaded to a threaded tube 11. An operating ring 12 is fixedly connected to the side of the threaded tube 11 away from the instrument cylinder 6. An operating rod 13 is fixedly connected to the side of the operating ring 12 away from the threaded tube 11. An annular anti-slip pad 14 is fixedly connected to the side of the operating ring 12. The side of the annular anti-slip pad 14 away from the operating ring 12 is in contact with the side of the semi-limiting ring 1 3 and the semi-limiting ring 2 5. The fixed and moving modes can be switched, which is convenient for fine-tuning the position of the instrument and fixing and supporting the instrument.
[0027] A hysteroscope 15 is slidably connected through the inner wall of the semi-endoscopic tube 2. A limiting ring 16 is fixedly sleeved on the surface of the hysteroscope 15. One side of the limiting ring 16 is attached to the side of the semi-endoscopic tube 2. The hysteroscope 15 is used to observe the lesions in the patient's body.
[0028] An infusion tube 17 is slidably connected through the inner wall of the semi-infusion cylinder 4. A limiting ring 18 is fixedly sleeved on the surface of the infusion tube 17. One side of the limiting ring 18 is attached to the side of the semi-infusion cylinder 4. The two infusion tubes 17 are used for infusing and draining physiological saline.
[0029] Both the outer surfaces of the first and second semi-protective cylinders 1 and 2 are fixedly connected with handles 19, which facilitate gripping and moving the positions of the first and second semi-protective cylinders 1 and 2.
[0030] Working principle: The first and second protective tubes (1 and 7) are joined together. Then, screw 10 is inserted into threaded hole 8. Using a screwdriver, screw 10 is rotated through threaded holes 8 and 9 to secure the first and second protective tubes (1 and 7) together. At this point, the two semi-endoscope tubes (2) and the two sets of semi-infusion tubes (4) are joined together. The hysteroscope (15) is then passed through the semi-endoscope tube (2), and the infusion tube (17) is passed through the semi-infusion tube (4). Limiting rings 16 and 18 both act as limiting rings, preventing the hysteroscope (15) and the infusion tube from moving together. The front end of tube 17 is flush with the front ends of semi-protective tube 1 and semi-protective tube 2 7. Holding the handle 19, semi-protective tube 1 and semi-protective tube 2 7 are inserted into the patient's body. The lesion in the uterine cavity is observed through the hysteroscope 15. The infusion and drainage of normal saline are achieved through the two infusion tubes 17. When it is necessary to insert instruments for operation, the two instruments are inserted into the instrument tube 6 through the operating ring 12 and the threaded tube 11, and the front end of the instrument is brought to the lesion. Then, holding the operating handle 13, the operating ring 12 and the threaded tube 11 are rotated to make the annular anti-slip pad... 14 detaches from the sides of the semi-limiting rings 3 and 5, allowing the instrument tube 6 to move. The semi-limiting rings 3 and 5 limit the instrument tube 6, preventing it from tilting or sliding out of the semi-protective tubes 1 and 2. This allows the instrument tube 6 to move along the gap between the semi-protective tubes 1, 2, and 2, thus changing the position of the instrument tip and facilitating operation and adjustment. After determining the operating position, the operating ring 12 and threaded tube 11 are rotated to press the annular anti-slip pad 14 against the sides of the semi-limiting rings 3 and 5, fixing the position of the instrument tube 6. Both instruments can be operated simultaneously, increasing the operating range. This solves the problem that traditional hysteroscopic instruments often have only one operating channel, requiring the removal of one instrument before inserting another when multiple instruments are needed, hindering the coordinated operation of two instruments and reducing efficiency due to frequent switching. After the operation, the semi-protective tubes 1 and 2 can be disassembled for internal sterilization.
