Problems solved by technology

[0002] Curettage and curettage refers to the operation of scraping or collecting endometrial tissue in the patient's uterus, especially for the removal of residual tissue after abortion and the analysis of pathological tissues of uterine diseases, curettage is often a must Surgery, not only can help doctors to diagnose patients, but also is a relatively direct and reliable treatment method for patients, especially for abortion surgery, if the residual tissue in the uterus is not removed in time, it is not only easy Cause gynecological inflammation, and may further affect women's fertility, and the existing dilatation and curettage operation is generally divided into two steps, the first step is to expand the cervix to make it meet the requirements for the insertion of surgical instruments, usually The vagina will be expanded together to ensure that the medical staff can operate more directly and conveniently. Sometimes it is even necessary to clamp the patient's uterus with surgical forceps so that it will not be affected by a large displacement during the curettage operation. normal operation; the second step is to extend the curettage device into the uterus to scrape the tissue of the patient's uterus. It is necessary to repeatedly insert and reciprocate the curettage instrument to remove the tissue from the uterus. This not only makes the patient's cervix scraped many times during the operation, but also because the tissue in the uterus is relatively sen...

Embodiment 1

[0052] combine Figures 1 to 3 As shown in one of the present embodiments, an obstetric curettage device is disclosed, which includes:

[0053] The handle 1 is a flat rod-shaped structure;

[0054] The spatula 2 has a spoon-shaped structure and is fixed at one end of the handle 1, which can be screwed and fixed by a headless bolt 31;

[0055] The scraper 3 is a strip structure formed of flexible material, one end of which is fixed on the end of the scraper 2 away from the handle 1, and the other end extends along the direction close to the handle 1 and crosses the convex surface of the scraper 2, the scraper 2 3. The elastic strip structure can be formed by medical stainless steel or titanium alloy or pure titanium, and its circumference is rounded to avoid sharp scratches on the patient's mucous membrane;

[0056] The connecting strip 4 is slidably attached to the end surface of the handle 1 and the convex surface of the spatula 2, and one end is rotationally connected with...

Embodiment 2

[0062] combine Figure 1 to Figure 3 and Figure 5 to Figure 7 As shown in one of the above, this embodiment proposes another superposition implementation mode on the basis of the technology of embodiment 1.

[0063] As a preferred implementation mode, the solution of this embodiment also includes on the technical basis of Example 1:

[0064] The first operating cylinder 5 is a cylindrical structure with both ends open, and an operating channel for the handle 1 and the scraper 2 to penetrate is formed in the cylindrical structure;

[0065] A plurality of expansion plates 61 are arranged in an annular array on the outer peripheral side of one end of the first operating cylinder 5, and the end of the expansion plate 61 close to the end of the first operating cylinder 5 is an arc-shaped structure, and the arc structure is close to the first operating cylinder. 5 profiling bending;

[0066] A plurality of rotating connection seats 62 are fixedly arranged on the outer peripheral...

Embodiment approach

[0082] combine Figure 1 to Figure 3 and Figure 11 to Figure 12 One shows that this embodiment is roughly the same as Embodiment 2, the difference is that this embodiment is another preferred implementation of the expansion drive mechanism 7, and the expansion drive mechanism 7 includes:

[0083] Several connection sleeves 76 correspond to several expansion plates 61 one-to-one, and are a cylindrical structure with one end open. The outer peripheral side of one end of the first operation cylinder 5 is correspondingly provided with connection holes 53 corresponding to several connection sleeves 76 one-to-one. , several connecting sleeves 76 are threadedly connected to the corresponding connecting holes 53, and the open ends of the connecting sleeves 76 face the corresponding expansion plate 61, and the center of the other end of the connecting sleeves 76 is provided with a through hole 761;

[0084] Several connection springs 77 correspond to several connection sleeves 76 one...

Abstract

The invention discloses a dilatation and curettage device for obstetrics department. The dilatation and curettage device comprises a handle, a curettage spoon, a curettage strip, and a connecting strip, wherein the handle adopts a flat rod structure; the curettage spoon adopts a spoon structure and is fixed to the end tail of the handle; the curettage strip adopts a strip structure formed by flexible materials; one end of the curettage strip is fixed to the end away from the handle, of the curettage spoon, and the other end of the curettage spoon extends in the direction approaching the handleand crosses the protruding surface of the curettage spoon; the connecting strip is in sliding joint to the end surface on the same side of the protruding surface of the curettage spoon, of the handle, one end of the connecting strip is rotatably connected to the other end of the curettage strip, and the other end of the connecting strip extends to the end away from the curettage spoon, of the handle; a plurality of first positioning sleeves which are arranged in the axial direction in a spaced manner are arranged corresponding to the connecting strip, of the handle; the connecting strip sequentially penetrates through the first positioning sleeves, and the connecting strip slides in the axial direction of the handle to drive the curettage strip to be partially jointed to the protruding surface of the curettage spoon or drive the curettage strip to bend and deform, so that a gap is formed between the curettage strip and the protruding surface of the curettage spoon; and besides, a first operation cylinder and an expansion mechanism are also arranged to enable the dilatation and curettage device for obstetrics department to be suitable for more surgery operation situations; and thescheme of the dilatation and curettage device for obstetrics department is reliable in implementation and flexible in operation.
