Abstract
Description
Technical Field
[0001] The invention relates to the technical field of hysteroscopy, in particular to a cervical clamp used for preventing water leakage during hysteroscopy. Background Art
[0002] Hysteroscopy is a new, minimally invasive gynecological diagnostic and treatment technique that uses a fiber-optic light-emitting endoscope to enter the uterine cavity through the cervix for direct observation of the interior of the uterus. This examination method combines a hysteroscope, an energy system, a light system, a perfusion system, and an imaging system to magnify the observation area, providing doctors with a clear field of view and enabling accurate diagnosis of various gynecological conditions.
[0003] Before surgery, the doctor will activate the perfusion system to expand the uterus. This maintains intrauterine pressure and provides cooling and flushing. However, in clinical practice, the cervix is often too tight or too loose. For a tight cervix, we often use various medications or dilators to dilate and soften the cervix, with significant results.

DETAILED DESCRIPTION
[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0025] like Figure 1-3 As shown, a cervical forceps for preventing leakage during hysteroscopy includes two forceps bodies. The middle sections of the two forceps bodies are rotatably connected by a rotating shaft. The rotating shaft divides the forceps bodies into left and right sections. The two forceps bodies are arranged in an X array. The two forceps bodies are composed of a gripping rod 11 and a clamping rod 12. The gripping rod 11 and the clamping rod 12 are respectively located on the left and right sides of the rotating shaft. The gripping rod 11 and the clamping rod 12 can rotate around the rotating shaft. The two clamping rods 12 rotate in opposite directions. The sides of the two gripping rods 11 that are close to each other are in contact with each other. A cavity is defined between the two clamping rods 12.
[0026] The two clamping rods 12 are provided with a clamping part at one end away from the gripping rod 11, and the clamping part is located in the cavity. The two clamping parts are arranged in an upper and lower array. When the two clamping rods 12 rotate, the two clamping parts can be driven to move toward or away from each other. When the two clamping parts move toward each other, the front lip and the back lip of the cervix can be clamped to prevent leakage of uterine distension fluid in the uterus. A sealing plug 3 is provided in the cavity. The sealing plug 3 can be inserted into the cervical opening to seal the cervical opening. The sealing plug 3 is in the shape of a truncated cone, and the diameter of the sealing plug 3 is from one end close to the cervix to the end away from the cervix. One end of the cervix gradually tapers, thereby being able to seal cervical openings of different sizes. When the cervix is not clamped, the sealing plug 3 can be stored in the clamping portion, thereby conveniently protecting and storing the sealing plug 3. When the two clamping portions move toward each other, the sealing plug 3 can move toward the cervical opening. When the two clamping portions clamp the uterus, the sealing plug 3 can be inserted into the cervical opening, thereby sealing the cervical opening and further preventing leakage of uterine distension fluid in the uterus, thereby enabling doctors to perform surgery more conveniently and reducing surgical risks.
[0027] The two holding rods 11 are provided with a driving part for driving the two holding rods 11 to rotate. When the holding rods 11 rotate, the clamping rods 12 can be driven to rotate and the holding rods 11 can be positioned without the doctor having to apply continuous force to clamp the cervix. A connecting part is provided in the cavity. When the two clamping rods 12 rotate, the sealing plug 3 can be driven to move, so that the sealing plug 3 can be conveniently driven to seal the cervical opening. A mounting part is provided on the connecting part, and the sealing plug 3 is installed on the connecting part through the mounting part, and can detect the pressure of the uterine distension fluid in the uterus to avoid the impact of too high or too low pressure on the operation.
[0028] like Figure 1 and Figure 2 As shown, the clamping part includes a clamping plate 21, and the two clamping plates 21 are respectively rotatably connected between the two clamping rods 12, and the clamping plate 21 is located at the end of the clamping rod 12 away from the gripping rod 11. The two clamping plates 21 are close to each other on one side and are provided with an arc-shaped groove 22. When not in use, when the clamping rod 12 rotates to drive the two clamping plates 21 to contact each other on one side, the sealing plug 3 can be stored in the arc-shaped groove 22, so that the sealing plug 3 can be conveniently stored and protected, and the arc-shaped groove 22 is arc-shaped, which can effectively increase the contact area with the front lip and the back lip of the cervix, and more conveniently clamp the front lip and the back lip of the cervix.
[0029] It should be noted that the sealing plug 3 and the clamping plate 21 can be made of soft materials such as soft rubber to improve the patient's comfort when sealing the cervical os.
[0030] like Figure 1 and Figure 2 As shown, the driving part includes a slide rail 41 arranged on the rotating shaft on one side of the gripping rod 11, and two other first sliders 42 are slidably connected in the slide rail 41. Two second sliders 43 are rotatably connected to the two first sliders 42, and the two second sliders 43 are respectively located above and below the two gripping rods 11. A first slide groove 44 is provided on one side of the two gripping rods 11 close to the second slider 43, and the second slider 43 is slidably connected in the first slide groove 44. A bidirectional screw rod 45 is threadedly connected to the two first sliders 42, and the top end of the bidirectional screw rod 45 extends to the top of the slide rail 41. The top end of the bidirectional screw rod 45 is fixedly connected to the turning handle 46. The bidirectional screw rod 45 is rotated by rotating the handle 46, and then the rotation of the bidirectional screw rod 45 can drive the two first sliders 42 to move toward or away from each other, and then the first slider 42 moves toward each other to drive the second slider 43 to move, and the movement of the second slider 43 can drive the holding rod 11 to rotate around the rotation axis, thereby driving the clamping rod 12 to rotate, so that the clamping plate 21 clamps the front lip and the back lip of the cervix, and the self-locking between the bidirectional screw rod 45 and the first slider 42 can position the holding rod 11, and the doctor does not need to apply continuous force to clamp the front lip and the back lip of the cervix.
[0031] like Figure 1-3 As shown, the connecting part includes two connecting rods 51 that are rotatably connected to the side surfaces of the two clamping rods 12 that are close to each other, and the ends of the two connecting rods 51 that are close to each other are hinged, and the ends of the two connecting rods 51 that are close to each other are hinged with a mounting plate 52, and the sealing plug 3 is installed on the mounting plate 52. When the angle between the two clamping rods 12 changes from large to small, the mounting plate 52 can move toward the cervix. Conversely, when the angle between the two clamping rods 12 changes from small to large, the mounting plate 52 can move away from the cervix. When the mounting plate 52 moves, it can conveniently drive the sealing plug 3 to move to seal the cervical opening.
[0032] like Figure 3 As shown, the mounting portion includes a second slide groove 81 opened in the sealing plug 3, and a slide plate 82 is slidably connected in the second slide groove 81. The side of the slide plate 82 close to the mounting plate 52 is fixedly connected to the mounting rod 83, and the end of the mounting rod 83 close to the mounting plate 52 extends to the outside of the sealing plug 3 and is fixedly connected to the mounting plate 52. A pressure sensor 84 is installed on the side of the slide plate 82 away from the mounting rod 83. When the sealing plug 3 is inserted into the cervical opening, the pressure difference between the inside and outside of the uterus will push the sealing plug 3 to move toward the mounting plate 52. When the sealing plug 3 moves, it will squeeze the pressure sensor 84, so that the pressure value of the uterine distension fluid in the uterus can be conveniently detected, thereby effectively improving the safety of the operation.
[0033] like Figure 1 and Figure 2As shown, a fixing plate 6 is fixedly connected to the slide rail 41, and one end of the fixing plate 6 away from the slide rail 41 is fixedly connected to the rotating shaft. A T-shaped handle 7 is fixedly connected to the side of the slide rail 41 away from the gripping rod 11, which enables the doctor to easily pick up and fix the forceps.
[0034] Working principle: The doctor picks up the forceps by holding the T-shaped handle 7, and then drives the turning handle 46 to rotate, so that the two second sliders 43 move toward each other, and the holding rod 11 and the clamping rod 12 rotate around the rotation axis. At this time, the ends of the two clamping rods 12 away from the holding rod 11 will move toward each other, and then the two clamping plates 21 will move toward each other to clamp the front and back lips of the cervix. When the two clamping plates 21 move toward each other, they can drive the sealing plug 3 to move toward the cervical opening through the connecting part. When the two clamping plates 21 clamp the cervix, the sealing plug 3 can be inserted into the cervical opening, so that the clamping of the cervix by the two clamping plates 21 and the sealing of the cervical opening by the sealing plug 3 can effectively prevent the leakage of the distending fluid in the uterus, and avoid the leakage of the distending fluid affecting the clarity of the surgical field of view, thereby effectively improving the safety of the operation and reducing the risk of the operation. Through the provided installation part, the pressure value of the distending fluid in the uterus can be detected to prevent the pressure value from being too high or too low, thereby improving the safety of the operation.
