Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a vaginal speculum for gynecological surgery. Background Art

[0002] The vaginal speculum has important applications in gynecological surgery. During gynecological surgeries such as cervical conization and colposcopy, doctors use a vaginal speculum to expose the surgical area, making the surgery more precise and safe. Currently, the vaginal speculums used clinically only have two upper and lower blades. For some obese patients and patients with vaginal relaxation, the support of only the two upper and lower blades cannot fully expose the cervix, and the bulging of the side walls will make it difficult to expose the cervix. For some existing vaginal speculums with side blades, the support position of the side blades cannot be changed. Gynecological surgeries often use an electric scalpel for cutting and hemostasis, etc. However, during the electrocision or electrocoagulation of the electric scalpel, smoke will be generated locally, causing the surgeon to be unable to see the surgical field clearly. At this time, the surgery needs to be temporarily stopped, and the surgery will continue after the smoke is sucked out. Moreover, the smoke contains a large amount of harmful substances, posing a threat to the health of medical staff. Therefore, a smoking device is used during the surgery to absorb the smoke.

[0003] Chinese Utility Model CN215605601U discloses a chimney-type smoking and vaginal dilator, which includes an upper dilating piece and a smoking cavity and a smoking tube that are interconnected. A groove body is fixedly connected below the upper dilating piece, and the groove body and the upper dilating piece form the smoking cavity. The smoking tube is arranged at the rear of the upper dilating piece; a smoking port is opened at the front end of the groove body. This utility model can directly and quickly absorb the smoke by fixing the groove body and the upper dilating piece together to form a fixed smoking cavity and opening a smoking port at the front end of the groove body, so as to discharge the smoke into the smoking tube; thereby improving the surgical efficiency. However, during the use process, there are the following two problems:

[0004] 1. This dilator cannot fully expose the cervix for some obese patients and patients with vaginal relaxation. The bulging of the side walls will make it difficult to expose the cervix, resulting in difficulty in observing the cervix and bringing certain inconvenience to the surgical operation.

[0005] 2. The smoking port is located below the upper dilating piece. When the surgical site is far from the upper dilating piece, the smoking effect is poor. Summary of the Utility Model

[0006] The utility model provides a vaginal speculum for gynecological surgery, aiming to solve the problems of insufficient cervix exposure and poor smoking effect existing in the existing vaginal speculums.

[0007] To achieve the above purpose, the technical idea adopted by the utility model to solve its technical problems is as follows:

[0038] Next, the technical solutions in the embodiments will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments. Embodiment 1

[0039] Reference Figures 1-4 , the present invention provides a vaginal speculum for gynecological surgery, including an upper blade 1, a lower blade 2, a movable side lobe 3 and an annular slide rail 4. The movable side lobe 3 is located between the upper blade 1 and the lower blade 2. The lower side of the rear end of the upper blade 1 is slidably connected to the annular slide rail 4, the lower end of the annular slide rail 4 is fixedly connected to the adjusting arm 41, and a vertical chute is provided on the adjusting arm 41. The rear end of the lower blade 2 extends downward to form a handle 21. The adjusting arm 41 and the handle 21 are slidably connected by a prior art threaded rod and an adjusting knob. The threaded rod passes through the chute and is fixedly connected to the handle 21. The adjusting knob is located at the rear side of the adjusting arm 41, and the threaded rod and the adjusting knob are engaged to control the opening and closing of the upper blade 1 and the lower blade 2. The sliding member 5 is connected to the rear end of the movable side lobe 3 and is used to drive the movable side lobe 3 to rotate along the inner wall of the annular slide rail 4, which can further support the cervix, help provide a better surgical field of view, and improve the surgical efficiency. The whole of the present invention is made of stainless steel, which is convenient for multiple uses and disinfection.

[0040] The upper blade 1 and the lower blade 2 belong to the conventional technologies in the field and will not be elaborated here.

[0041] Furthermore, the movable side lobe 3 is a hollow structure, including a main cavity wall 31, a main smoking cavity 32, a main smoking hole 33 and a main smoking pipe 34; the main smoking cavity 32 is divided into two parts by a partition 35 in the front end along the thickness direction and is communicated at the rear end. The main smoking holes 33 are located on both sides of the front end of the main cavity wall 31 along the width direction. The partition 35 is used to prevent the poor smoking effect caused by the direct opposition of the main smoking holes 33 on both sides; the main smoking pipe 34 is located at the rear end of the main cavity wall 31 and is communicated with the main smoking cavity 32. When one end of the main smoking pipe 34 far from the main smoking cavity 32 is connected to an air pump, the smoke is inhaled into the main smoking cavity 32 through the main smoking holes 33 and then discharged into the air pump through the main smoking pipe 34. To facilitate connecting the air pump through suction pipes with different pipe diameters, the connection port 36 at one end of the main smoking pipe 34 far from the main smoking cavity 32 is provided with a plurality of outer diameters from small to large.

[0042] Further, the outer main cavity wall 31 of the movable side lobe 3 is an arc-shaped structure, which is smooth and has no sharp corners, and will not scratch the patient after contacting the human body.

[0043] Further, referring to Figures 6-7 , a groove body 11 is connected to the lower side of the upper blade 1; the groove body 11 and the upper blade 1 form a secondary smoking cavity 12; a secondary smoking hole 13 is provided at the front end of the groove body 11; a secondary smoking pipe 14 communicating with the secondary smoking cavity 12 is connected to the rear end of the groove body 11.

[0044] In this embodiment, the main smoking hole 33 on the movable side lobe 3 is located above the vicinity of the surgical site, and can directly suck the smoke near the smoke generation point; the secondary smoking hole 13 on the upper blade 1 is used to absorb the smoke not absorbed by the main smoking hole 33, further ensuring the smoking effect. Embodiment Two

[0045] For the sliding member 5 in the above-mentioned Embodiment One, in order to enable it to drive the movable side lobe 3 to rotate 360° along the inner wall of the annular slide rail 4, on the basis of Embodiment One, the specific structure of the sliding member 5 is further improved. It should be clear that the improvement here is only the implementation manner thereof and should not be construed as a limitation on the structure of the present utility model.

[0046] Referring to Figure 2 、 Figure 5 , the sliding member 5 includes a slider 51, a bolt 52 and an anti-collision pad 53; the slider 51 is wrapped outside the cross-section of the annular slide rail 4; the bolt 52 passes through the rear side wall of the slider 51 and meshes with it, and is used to loosen or fasten the movable side lobe 3; the head of the bolt 52 is wrapped with the anti-collision pad 53, and the anti-collision pad 53 is preferably a flexible member, such as rubber, so as to reduce the damage to the annular slide rail 4 when the bolt 52 is tightened, avoid the generation of scratches due to metal friction and increase the disinfection difficulty, and the flexible member can better ensure the fastening effect.

[0047] Specifically, the inner diameter of the slider 51 in the left-right direction is larger than the outer diameter of the cross-section of the annular slide rail 4 in the left-right direction, so that the slider 51 can smoothly pass through the bend of the annular slide rail 4. The inner diameter of the slider 51 in the front-rear direction is larger than the outer diameter of the cross-section of the annular slide rail 4, so that the bolt 52 can slide back and forth to loosen or fasten the movable side lobe 3.

[0048] Referring to Figure 5 and Figure 8, an opening is provided inside the front end of the slider 51. The rear end of the upper blade 1 is connected to the inner part of the top of the annular slide rail 4 near the cross-section. The purpose of this design is to ensure that when the slider 51 slides to the top of the annular slide rail 4, the connection part of the upper blade 1 and the annular slide rail 4 is exactly at the opening position, without affecting the sliding of the slider 51. Similarly, the upper end of the adjusting arm 41 extends backward to form a connecting piece and is connected to the inner part of the bottom of the annular slide rail 4 near the cross-section to ensure that it does not affect the slider 51 passing through the bottom of the annular slide rail 4. It should be noted that the size of the opening here is larger than the size of the connection parts of the upper blade 1, the adjusting arm 41 and the annular slide rail 4.

[0049] Reference Figure 8 , the overall size of the movable side blade 3 is smaller than the inner diameters of the upper blade 1 and the lower blade 2. Therefore, when the movable side blade 3 slides to the top of the annular slide rail 4, the movable side blade 3 is located below and inside the upper blade 1; when the movable side blade 3 slides to the bottom of the annular slide rail 4, the movable side blade 3 is located above and inside the lower blade 2, ensuring that the upper blade 1 and the lower blade 2 do not affect the 360° sliding of the movable side blade 3.

[0050] Taking a cervical conization operation as an example, the application of a vaginal speculum for gynecological surgery in the cervical conization operation of the present application will be specifically described.

[0051] Cervical conization operations are generally used to treat cervical lesions, such as high-grade cervical intraepithelial neoplasia, pathological cervical erosion, etc. The operation process is to disinfect the vaginal area of the patient, then use a vaginal dilator to dilate the vagina of the female to fully expose the cervical area, fix the anterior lip of the cervix with a cervical clamp, and then perform conization on the cervix with a LEEP knife or a cold knife, and finally electrocoagulate to stop bleeding. During the actual operation, when facing some obese patients or patients with vaginal relaxation, common vaginal speculums cannot meet the requirements of the surgical field of view. At this time, a vaginal retractor has to be used, but the vaginal retractor needs to be fixed by a surgical assistant, which is inconvenient to use; and the smoke generated during the LEEP knife conization and electrocoagulation during the operation is difficult to disperse. The commonly used smoking tube blocks the surgical field of view and is far from the surgical site, resulting in poor smoking effect. The movable side blade 3 with the main smoking hole 33 of the present utility model can rotate 360°, has a good cervical exposure effect and a good smoking effect, and is especially suitable for performing gynecological surgery on obese or vaginal relaxation patients.

[0052] Before the operation, the patient lies in the supine position for intravenous general anesthesia, and then takes the lithotomy position, and the vaginal area of the patient is disinfected.

[0053] Pick up the vaginal speculum. At this time, the vaginal speculum is in the closed state, that is, the upper blade 1 and the lower blade 2 are in contact, and the movable side blade 3 is located at the top of the annular slide rail 4 and within the closed space formed by the upper blade 1 and the lower blade 2.

[0054] Insert the front ends of the upper blade 1 and the lower blade 2 into the patient's vagina, rotate the adjustment knob on the adjustment arm 41 to open the upper blade 1 and the lower blade 2 to the desired position and fix them. At this time, observe the patient's vagina, loosen the bolt 52, and slide the movable side lobe 3 above the vicinity of the surgical site and tighten the bolt 52 to fix it, so as to further expand the cervix and enlarge the surgical field of view. Connect the main suction pipe 34 to the air pump.

[0055] Fix the anterior lip of the cervix with a cervix clamp, turn on the air pump, and perform the surgical operation.

[0056] Turn off the air pump, loosen the bolt 52, and slide the movable side lobe 3 to the top of the annular slide rail 4. Loosen the adjustment knob on the adjustment arm 41 and slide the adjustment arm 41 upward until the upper blade 1 and the lower blade 2 come into contact.

[0057] Remove the vaginal speculum, and the operation is over.

[0058] It should be clear that the above detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the present invention claimed, but merely represents the selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts fall within the scope of protection of the present invention.
