Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a clinical intra-invasive examination device for obstetrics and gynecology. Background Art

[0002] Obstetrics and gynecology includes gynecology that treats diseases of the female reproductive system, as well as physiological obstetrics and pathological obstetrics, so its scope is wider than gynecology. Gynecological diseases include menstrual disorders, reproductive system inflammation, gynecological tumors, infertility, endometriosis, trophoblastic tumors, etc. Obstetrics and gynecology includes the above-mentioned gynecological diseases, as well as normal delivery, abnormal delivery, physiological pregnancy and pathological pregnancy.

[0003] At present, the existing obstetrics and gynecology clinical internal examination device generally uses a vaginal dilator to achieve internal examination. During the use of traditional vaginal dilators, it is generally difficult to control the adjustment force by pressing the handle, and it is not easy to control the size of the expansion according to needs. It is easy for the patient's vaginal opening to expand instantly, thereby causing painful injuries to the patient and increasing the burden on the patient. For this reason, we propose a gynecology and obstetrics clinical internal examination device. Summary of the invention

An adjustment groove is opened at the center position of the inner wall of the lower support body and the upper support body, and an adjustment screw is movably provided inside the adjustment groove through a bearing. A second threaded block is fixedly installed on the outer end of the extension body, and the second threaded block extends to the inside of the adjustment groove and is spirally connected to the adjustment screw inside it. A second knob is provided at one end of the adjusting screw, and an end of the adjusting screw close to the second knob is fixedly connected to the inner wall of the upper support body or the lower support body through a support rod.

[0007] Preferably, a return spring is arranged inside the spring sleeve, and two ends of the return spring are fixedly connected to the telescopic column and the spring sleeve respectively.

[0008] Preferably, second limiting grooves are formed on inner walls on both sides of the spring sleeve, and second limiting blocks are provided on both sides of the top of the telescopic column. The second limiting blocks extend into the second limiting grooves and are slidably connected to the inner walls thereof.

[0009] Preferably, both ends of the push rod are provided with movable connection seats, and the two ends of the push rod are movably connected to the first threaded block and the extension rod respectively through the movable connection seats.

[0010] Preferably, first limit blocks are provided on both sides of the first threaded block, and the first limit blocks are fixedly installed at the middle parts of both sides of the first threaded block by welding.

[0011] Preferably, first limiting grooves are provided on the inner wall surfaces on both sides of the slide groove, and the first limiting block extends into the first limiting groove and is slidably connected to the inner wall thereof.

[0012] Preferably, the inner wall surfaces on both sides of the upper support body and the lower support body are opened with a third limit groove, and the third limit blocks are arranged on both sides of the outside of one end of the extension body close to the second threaded block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By using the driving screw rod in conjunction with the transmission mode of the first threaded block, the push rod is driven to move, and under the action of the movable connection seat, the extension rod is pulled close to one side of the grip rod, so that the upper support body can rotate around the pin shaft, thereby achieving the purpose of expansion, and the spring sleeve and the telescopic column, the first knob, the positioning column and the positioning hole connected with the spring sleeve and the telescopic column, the first knob, the positioning column and the positioning hole are inserted into the positioning hole to achieve the purpose of positioning the driving screw rod, thereby avoiding the accidental touch of the first knob, resulting in accidental expansion again, causing discomfort to the patient.

[0015] 2. By arranging extension bodies on the inner sides of the lower support body and the upper support body, and using the adjusting screw and the second threaded block, the function of adjusting the outward extension length of the extension body is realized. During use, the extension length of the extension body can be adjusted according to the patient's own condition, so as to be suitable for different patients, thereby greatly improving its applicability.

[0016] 3. By means of the second limiting groove and the second limiting block, the spring sleeve is connected with the telescopic column due to the limiting sliding connection, so that while ensuring that the telescopic column and the inner wall of the spring sleeve can slide against each other, the function of stable transmission can also be maintained. The third limiting groove and the third limiting block are used to improve the stability of the extension body itself and avoid deformation or dislocation of the two extension bodies.
