Dilatation and curettage device for obstetrics department

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.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a curettage device for obstetrics. Background technique [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 ...

[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 sensitive and delicate, it is easy to cause the loss of the subsequent anesthesia effect. The patient has a relatively obvious pain in the lower abdomen, which may even last for a long time. This is the adverse postoperative reaction caused by the repeated reciprocating operations of the operation, which have caused certain damage to the tissues in the uterus and vagina. One of the reasons for the sequelae is that during the operation of dilatation and curettage, the surgical instruments are inserted into the vagina or uterus many times, so that the instruments scratch and drag the internal tissues and mucous membranes of the patient, resulting in tissue damage.

[0003] As we all know, different female patients have different physiological characteristics and physiological structures, and the existing surgical operations are often a set of streamlined or textbook-style operations, which also leads to different patients' post-duration dilation and curettage. The treatment experience is quite different, and some even suffer from more serious psychological diseases (such as psychological fear). With the continuous development of medical level, humanized and customized treatment concepts are constantly promoted, and the requirements for medical auxiliary equipment are also increasing. How to meet the requirements of humanized medical concept by improving traditional surgical instruments is also an important technical problem that people in this field need to solve urgently
