Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, in particular to a visual curettage device. Background Art

[0002] With the development of medical technology, curettage has gradually become known to people. Curettage refers to a surgery to scrape the endometrium or the contents of the uterine cavity. It is divided into diagnostic curettage (abbreviated as diagnostic curettage) and therapeutic curettage. Curettage has the functions of scraping the endometrium, clearing the decidua of pregnancy, and scraping off necrotic tissue.

[0003] Common curettage devices generally include vaginal dilator forceps, cervical forceps and a curette. The function of the vaginal dilator forceps is to open the access canal to increase the operating space for the operation. After vaginal dilator forceps can open the cervix and the curette can enter the uterus for surgery. The existing curettage device makes the surgical operation more flexible and convenient, the gas conduction effect is better, and at the same time simplifies the instrument structure, making the instrument preparation simpler and the cost lower.

[0004] The existing vaginal dilator does not have fixed positions for the cervical clamp and the hysteroscope, and may repeatedly extend into the introduction canal during use, which will affect the surgeon's attention and increase the difficulty of operation. In addition, the existing vaginal dilator cannot control the dilation force well. Summary of the invention

[0005] The utility model aims to provide a visual curettage device, which can place the cervical clamp and the hysteroscope at fixed positions, and at the same time, the surgeon can more easily control the force of vaginal dilation.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: comprising a lower blade base and a first connecting member arranged obliquely, a connecting portion is provided between the lower blade base and the first connecting member, and a through hole for operation is provided on the first connecting member;

[0007] The lower leaf base is provided with a hysteroscope channel, a hysteroscope is installed in the hysteroscope channel, and the hysteroscope extends to the outside through the through hole, and the hysteroscope channel is fixedly connected to the lower leaf base; the first connecting member is provided with a cervical clamp channel located above the lower leaf base, a cervical clamp is installed in the cervical clamp channel, and the cervical clamp extends to the outside through the through hole, and the cervical clamp channel and the cervical clamp channel both pass through the through hole for operation provided on the first connecting member;

[0008] The first connecting member is provided with an upper leaf located above the lower leaf base, and the upper leaf is fixedly connected to the first connecting member; the first connecting member is provided with a rack located below the lower leaf base, and the rack is fixedly connected to the first connecting member; the lower leaf base is provided with a second connecting member, and the second connecting member is fixedly connected to the lower leaf base, and the second connecting member is provided with a gear meshing with the rack;

[0009] The first connecting member passes through the second connecting member, and the first connecting member and the second connecting member are slidably matched.

[0010] The above scheme has the following principles and beneficial effects: when in use, the surgeon can insert the upper leaf and the lower leaf base into the vagina, and the surgeon drives the rack to move upward or downward by rotating the gear provided on the second connecting piece, thereby controlling the first connecting piece to drive the upper leaf to open and close. The cervical clamp can be inserted into the vagina through the cervical clamp tube to open the cervix, and the hysteroscope is inserted into the vagina through the hysteroscope tube, and the scraper is inserted into the vagina through the operating through hole provided on the first connecting piece.

[0011] The gear drives the rack to move upward or downward to accurately control the opening and closing force of the upper leaf, and can reduce the situation where the patient's vaginal opening is torn due to inaccurate force control. The cervical clamp tube can place the cervical clamp in the cervical clamp tube, and when the cervical clamp is inserted into the patient's vagina, the cervical clamp tube can prevent the cervical clamp from colliding with the inner wall of the vagina. The hysteroscope tube can place the hysteroscope in the hysteroscope tube, and when the hysteroscope is inserted into the patient's vagina, the hysteroscope tube can prevent the hysteroscope from colliding with the inner wall of the vagina.

[0012] Furthermore, a handle is provided at one end of the lower leaf base close to the second connecting piece, and the handle is fixedly connected to the lower leaf base.

[0013] Advantageous Effects: The handle can provide a place for the surgeon to grasp when inserting the upper and lower leaf bases into the patient's vagina.

[0014] Furthermore, the gear is provided with a rotating handle, and the rotating handle is fixedly connected to the gear.

[0015] Beneficial effect: Turning the handle can make the gear rotation easier to operate.

[0016] The second connecting member is an arc-shaped plate, and an arc-shaped groove is formed on the arc-shaped plate. The second connecting member passes through the arc-shaped groove and is slidably matched with the arc-shaped groove.

[0017] Beneficial effect: The arc-shaped plate enables the first connecting member to rotate clockwise or counterclockwise along the arc-shaped plate.

[0018] Furthermore, angle lines are arranged on the arc-shaped plate.

[0019] Beneficial effect: The angle line enables the surgeon to intuitively see the angle between the lower leaf base and the first connecting piece, thereby more accurately grasping the expansion force of the vagina.

[0020] Furthermore, the upper lobe is a smooth semi-cylinder with the arch surface facing upward and the rectangular surface facing downward.

[0021] Beneficial effects: The upper leaf is the main force output structure for vaginal expansion, and the upper leaf arch facing upward can prevent the edges and corners from scratching the inner wall of the vagina.

[0022] Furthermore, the handle is provided with an anti-slip groove.

[0023] Beneficial effect: The anti-slip groove can prevent the surgeon from being unable to hold the handle due to sticky liquid on the hand when holding the handle.

[0024] Furthermore, the connecting part between the lower blade base and the first connecting member is an iron sheet with a through hole, the connecting part of the lower blade base overlaps with the through hole of the connecting part of the first connecting member, and adjacent iron sheets are rotatably connected through the through hole.

[0025] Beneficial effect: Adjacent iron sheets are rotatably connected through the through holes, and will not block the operating through holes on the first connecting member.

[0026] Furthermore, a braking nut is provided on the second connecting member, and the braking nut is located on the opposite side of the rotating handle and is coaxial with the gear shaft.

[0027] Beneficial effect: After rotating the gear to adjust the upper leaf to a suitable angle, tighten the brake nut. The brake nut presses against the gear shaft through the second connecting piece to increase the friction of the gear shaft. When the friction is greater than the force transmitted from the upper leaf to the rack, the gear can no longer rotate, so that the vaginal dilator is always at a suitable dilation angle.

[0028] Additional aspects and advantages of the present invention will be described in part in the following description and will become apparent from the following description.

[0029] Obviously, or understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS
