Description

Technical Field

[0001] The present invention relates to the technical field of vaginal speculum, and more particularly to a vaginal speculum used for fully exposing the cervix of obese patients. Background Art

[0002] The female speculum is a commonly used tool in physical examinations in obstetrics and gynecology. It needs to be inserted into the vagina to expose the cervix and complete the specialized examination. However, some patients are obese, have deep vaginas, and have poor cooperation, making it difficult to expose the cervix. Clinical speculum usually has only two leaves, which can only expand the anterior and posterior walls of the vagina. For obese patients or those with loose vaginas, when an ordinary speculum is inserted, the left and right walls of the vagina will be squeezed into the middle of the vagina, blocking the field of view and imaging operations.

[0003] In this regard, reference may be made to the prior patent with application number CN202122852179.1, which is a special speculum for surgery that can protect the vaginal wall, and specifically discloses that a silicone membrane is provided to achieve isolation of both sides. In addition, reference may also be made to the prior patent with application number CN202020943705.8, which is a special speculum for pregnant women with a detachable protective cover, and specifically discloses that an elastic protective cover is provided to achieve blocking of loose vaginal wall tissue. Although the above method can achieve a blocking effect, it still has the following defects:

[0004] 1. Since this type of method uses membrane isolation, the support effect on both sides is not good, and there is still a defect of poor vision caused by the vaginal wall tissue being squeezed inward;

[0005] 2. After the speculum is opened, medical staff will still adjust the position of the speculum for use needs. The above method will cause the surface of the speculum to be uneven, and then form a sharp angle on the blade, causing great pain to the patient during the process of adjusting the position of the speculum. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a speculum for fully exposing the cervix of obese patients, which can provide good support on both sides and reduce the sharp angles of the surface to alleviate the patient's pain during the position adjustment process.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are represented by the same reference numerals.

[0027] like Figure 1-5 As shown, a speculum for fully exposing the cervix of an obese patient comprises an upper leaf 1, a lower leaf 3 and a side leaf 5, wherein the upper leaf 1 and the lower leaf 3 are symmetrically arranged up and down, the side leaves 5 are 2 in number and are symmetrically arranged between the upper leaf 1 and the lower leaf 3, specifically, the two side leaves 5 are arc-shaped and symmetrically arranged left and right, and the bending direction of the arc is the direction in which the two side leaves 5 move away from each other.

[0028] Furthermore, the rear end of the upper leaf 1 is connected to an adjusting handle 2 . In the present embodiment, the adjusting handle 2 and the upper leaf 1 are formed as one piece.

[0029] Furthermore, a handle 4 is connected to the rear end of the lower leaf 3 , and the handle 4 is integrally formed with the lower leaf 3 .

[0030] Furthermore, the position of the upper leaf 1 is adjustable along the axis direction perpendicular to the lower leaf 3. At the same time, a clamping structure is provided between the handle 4 and the adjustment handle 2, and the clamping structure is used to fix the relative position of the adjustment handle 2 and the handle 4 to keep the upper leaf 1 and the lower leaf 3 in an open / closed state.

[0031] Furthermore, inclined first guide surfaces 6 are formed at both ends of the side leaves 5, and the end of the first guide surface 6 away from the side leaf 5 is connected to a mounting surface 8, and a slider 9 is provided on the mounting surface 8. Second guide surfaces 7 are formed on the sides where the upper leaf 1 and the lower leaf 3 are close to each other. The first guide surfaces 6 are used to cooperate with the second guide surfaces 7 and guide the side leaves 5 on both sides to move in a direction close to each other. The upper leaf 1 and the lower leaf 3 are provided with sliding grooves 10 corresponding to the sliders 9. When the slider 9 moves to the end of the sliding groove 10, the outer edges of the upper leaf 1, the lower leaf 3 and the two side leaves 5 are aligned with each other and form a circle along the axial direction.

[0032] Specifically, the side leaf 5 is made of a variable material, the slider 9 is made of an elastic material, and the slider 9 has a T-shaped cross section, and its head and the slide groove 10 are limited and slided.

[0033] In the initial state, the upper leaf 1 and the lower leaf 3 fit against each other, and the two side leaves 5 are retracted in the cavity formed by the upper leaf 1 and the lower leaf 3. At this time, the speculum is in the smallest state, which is convenient for entering the vagina. After the entry is completed, the adjustment handle 2 and the grip 4 are both located outside the human body. The operator adjusts the adjustment handle and the grip 4 to achieve the opening of the upper leaf 1 and the lower leaf 3. At this time, since the moving direction of the upper leaf 1 is perpendicular to the axial direction of the lower leaf 3, the gap between the upper leaf 1 and the lower leaf 3 can be made consistent along the length direction during the separation of the upper leaf 1 and the lower leaf 3. At the same time, during the separation of the upper leaf 1 and the lower leaf 3, the slider 9 can be naturally driven to slide in the slide groove 10. Therefore, when the slider 9 slides to the end of the slide groove 10, the outer edges of the upper leaf 1, the lower leaf 3 and the two side leaves 5 are aligned, thereby forming a circle along the length direction of the speculum, so that the operator can adjust the position of the speculum according to the specific conditions in the vagina after opening.

[0034] The arc-shaped side leaves 5 can provide good support effects on both sides of the speculum after being opened, so as to avoid the side collapse and adverse effects on the field of vision.

[0035] At the same time, the circle formed by the upper leaf 1, the lower leaf 3 and the two side leaves 5 can minimize the generation of sharp angles on the surface and reduce damage to the vagina during activities in the vagina.

[0036] Preferably, the clamping structure includes an elastic sheet 11 , and guide grooves 12 are symmetrically provided on the handle 4 , the guide grooves 12 are arranged along the axis direction of the vertical lower leaf 3 , and the adjustment handle 2 is provided with a guide block 13 corresponding to the guide groove 12 and limitedly slides with the guide groove 12 .

[0037] The moving direction of the upper leaf 1 is restricted by the guide block 13 and the limiting sliding of the guide block 13 .

[0038] Preferably, the adjusting handle 2 is provided with a mounting groove 14, one end of the elastic sheet 11 is connected to the mounting groove 14, the elastic sheet 11 is provided with a clamping block 15, and the grip 4 is provided with a clamping groove 16, the clamping block 15 is used to clamp the clamping groove 16 to limit the adjusting handle 2 from returning to its original position relative to the grip 4.

[0039] The elastic sheet 11 cooperates with the clamping block 15 and the clamping slot 16 to realize the quick fixing and separation of the position of the adjustment handle 2 and the grip 4, thereby facilitating operation and use.

[0040] Preferably, two arc-shaped covers 17 are further included, and an adjustment portion 18 is formed at the front end of the upper leaf 1 and the lower leaf 3. A connecting piece 19 is provided on the cover 17 and is movably connected to the adjustment portion 18 through the connecting piece 19, so that the two cover bodies 17 move in an arc shape in opposite directions.

[0041] The cover body 17 can swing relative to the upper leaf 1 and the lower leaf 3 through the movable connection of the connecting member 19, so that a wider field of view can be obtained, thereby reducing the adverse effects of the cover body 17 on the field of view.

[0042] Preferably, the connecting member 19 is an arc-shaped spring sheet, and the adjusting portion 18 forms a control groove 20 along the length direction. A control block 21 is provided at one end of the spring sheet, and the control block 21 is used to drive the spring sheet to move forward and backward along the control groove 20. The control groove 20 is used to flatten the spring sheet so that the cover body 17 is in contact and aligned with the adjusting portion 18.

[0043] When in use, the operator pulls / pushes the control block 21 through an instrument to adjust the elastic position. The arrangement of the arc-shaped spring piece can make the overall structure simpler and more reliable.

[0044] Preferably, a first magnetic member 22 is symmetrically provided at the end of the slide slot 10 , and a second magnetic member 23 is provided on the mounting surface 8 corresponding to the first magnetic member 22 and is magnetically connected to the first magnetic member 22 .

[0045] By providing the first magnetic member 22 and the second magnetic member 23, the position of the side leaf 5 can be fixed by magnetic adsorption after the side leaf 5 moves to a predetermined position, so as to further reduce the dislocation caused by the compression of the inner wall of the vagina.

[0046] Preferably, the tail of the upper blade 1 and the tail of the lower blade 3 are both provided with a soft installation station 24, and the installation station 24 is used to install a lamp tube, a smoke pipe or a drainage pipe.

[0047] By setting up the installation station 24, different instruments can be installed according to different surgical needs to facilitate clinical operation.

[0048] Preferably, the upper leaf 1 and the lower leaf 3 form a slot 25 with one end penetrating therethrough corresponding to the installation station 24 , the upper end of the slot 25 is open and covered with an elastic membrane 26 , and an opening 27 is formed at the front end of the slot 25 .

[0049] The slot 25 and the elastic membrane 26 can be arranged to keep the surface flat when not in use, so as to facilitate the entry of instruments into the vagina for operation. Meanwhile, the elastic membrane 26 can also be adapted to the use of instruments of different sizes.
