Description

Technical Field

[0001] The utility model relates to the technical field of fallopian tube angiography, in particular to a fixable fallopian tube angiography component. Background Art

[0002] Among the causes of female infertility, fallopian tube obstruction accounts for a large proportion, with statistics ranging from 30% to 50%. The simplest and most effective method for diagnosing fallopian tube obstruction is hysterosalpingography. In addition to traditional gynecological surgery, the current method of treating fallopian tube obstruction is interventional recanalization. Because it is simple, convenient, effective, and has low technical requirements, it is very common in hospitals at all levels.

[0003] There are many existing technologies for salpingography components, such as:

[0004] Chinese patent publication number CN219783493U discloses a radiographic fluid passage device, comprising an inner tube and an outer tube; the inner tube is inserted into the outer tube; an injection port is provided at the distal end of the inner tube, and a conical head is provided at the other end; a cervical covering device is provided on the outer tube, and the cervical covering device comprises a clamping piece, a connecting rod mechanism, a first fixed bracket, a second fixed bracket, and a reciprocating rod; the clamping piece is installed on the connecting rod mechanism; one end of the connecting rod mechanism is fixed to the first fixed bracket, and the other end is fixed to the second fixed bracket; the first fixed bracket is provided on the reciprocating rod; the second fixed bracket is provided on the outer tube; a sliding tooth is provided on the reciprocating rod; an adjustment knob is also provided on the cervical covering device; the adjustment knob is provided with conical teeth; the conical teeth engage with the sliding teeth on the reciprocating rod.

[0005] It can be seen that most of the current fallopian tube angiography components include a cervical covering device, which blocks the cervical canal to prevent the contrast fluid from flowing out. However, the cervical covering device cannot exert a heavy force on the cervical canal. Excessive force will cause discomfort to the patient. The cervical covering device is the only fixing device of the entire angiography component that blocks the cervical canal and fixes it in the vagina. The force exerted by the cervical covering device on the cervical canal is too light, and it is difficult to fix the angiography component to the cervical canal.

[0006] In view of this, we propose a fixable salpingography component. Utility Model Content

[0007] The purpose of the present invention is to provide a fixable salpingography assembly to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A fixable salpingography assembly comprises an inner tube and an outer tube, wherein the inner tube is sleeved on the outer tube, and further comprises a connecting rod mechanism, wherein the connecting rod mechanism is located at the same side ends of the inner tube and the outer tube and is movably connected to the inner tube and the outer tube respectively; wherein the outer tube pushes the connecting rod mechanism, so that the connecting rod mechanism wraps the cervical canal and fixes the entire device in the vagina.

[0010] As a further solution of the present invention: a guide cone head is provided at one end of the inner tube, and the guide cone head is connected to the inner tube.

[0011] As a further solution of the present invention: the connecting rod mechanism includes a plurality of clamping jaws, one end of the clamping jaws is rotatably connected to the connection between the inner tube and the guide cone head, and the side of the clamping jaw away from the guide cone head is provided with an outer supporting clamp rotatably connected to the inner tube.

[0012] As a further solution of the present invention: a first push rod is rotatably connected between the outer tube and the outer supporting jaw, and a second push rod is connected between the holding jaw and the corresponding outer supporting jaw.

[0013] As a further solution of the present invention: a silicone sheet is provided at the contact end of the outer supporting clamping jaw and the vagina.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By arranging a connecting rod mechanism at the same side ends of the inner tube and the outer tube and using the outer tube to push the connecting rod mechanism, the connecting rod mechanism can both wrap the cervical canal and be fixed to the vagina, thereby enhancing the stability of the entire angiography assembly and avoiding the situation where only the cervical canal is wrapped and fixed, and the patient may feel uncomfortable due to excessive force or the entire device may be difficult to fix on the cervical canal due to insufficient force due to difficulty in controlling the force.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example

[0023] Currently, most hysterosalpingography components include a cervical covering device, which blocks the cervical canal to prevent the contrast fluid from flowing out. However, the cervical covering device cannot exert a heavy force on the cervical canal. Excessive force will cause discomfort to the patient. The cervical covering device is the only fixing device of the entire hysterosalpingography component that blocks the cervical canal and fixes it in the vagina. If the force exerted by the cervical covering device on the cervical canal is too light, it will be difficult to fix the hysterosalpingography component to the cervical canal.

[0024] Therefore, see Figure 1 、 Figure 2 and Figure 3 As shown, the purpose of this embodiment is to provide a fixable salpingography assembly, including an inner tube 1 and an outer tube 2, wherein the inner tube 1 is sleeved on the outer tube 2, and further comprising a connecting rod mechanism 3, which is located at the same side end of the inner tube 1 and the outer tube 2 and is movably connected to the inner tube 1 and the outer tube 2 respectively; when the outer tube 2 pushes the connecting rod mechanism 3, the connecting rod mechanism 3 opens, wrapping the cervical canal while fixing the entire device in the vagina.

[0025] The improvement of this embodiment lies in that a connecting rod mechanism 3 is provided at the same side end of the inner tube 1 and the outer tube 2, and the connecting rod mechanism 3 is pushed by the outer tube 2, so that the connecting rod mechanism 3 can both wrap the cervical canal and be fixed to the vagina, thereby enhancing the stability of the entire angiography assembly and avoiding the situation where when only the cervical canal is wrapped and fixed, the patient may feel uncomfortable due to excessive force or the entire device may be difficult to fix on the cervical canal due to insufficient force due to difficulty in controlling the force.

[0026] In order to facilitate the insertion of the inner tube 1 into the cervical os, so that the contrast fluid can be input into the uterine cavity through the inner tube 1, a guide cone head 11 is provided at one end of the inner tube 1. The guide cone head 11 is connected to the inner tube 1. Due to the conical shape of the guide cone head 11 itself, the inner tube 1 can be easily inserted into the cervical os.

[0027] Furthermore, the connecting rod mechanism 3 is disclosed:

[0028] The connecting rod mechanism 3 includes a plurality of holding jaws 34, one end of which is rotatably connected to the connection between the inner tube 1 and the guide cone 11. The side of the holding jaw 34 away from the guide cone 11 is provided with an outer supporting jaw 32 rotatably connected to the inner tube 1. The holding jaw 34 is used to wrap the cervical canal, while the outer supporting jaw 32 is used to fix the entire device to the vagina.

[0029] A first push rod 31 is rotatably connected between the outer tube 2 and the outer supporting jaws 32, and a second push rod 33 is connected between the holding jaws 34 and the corresponding outer supporting jaws 32. When the outer tube 2 moves in the opposite direction of the guide cone head 11, the outer tube 2 pushes the outer supporting jaws 32 to open through the first push rod 31, so that the outer supporting jaws 32 contact and fix the vagina. At the same time as the outer supporting jaws 32 open, the holding jaws 34 are driven to open through the second push rod 33, so that the holding jaws 34 wrap around the cervical canal.

[0030] In order to improve the patient's comfort when the connecting rod mechanism 3 is used, a silicone sheet 35 is provided at the contact end of the outer supporting clamp 32 with the vagina. The elasticity and softness of the silicone material are utilized to ensure that there is no significant stimulation or pressure when the vagina contacts the silicone sheet 35.

[0031] In summary, the working principle of this solution is as follows:

[0032] When using this device, insert one end of the guiding cone head 11 of the inner tube 1 into the vagina and push it toward the cervical canal until the guiding cone head 11 is inserted into the cervical opening. Then, pull the outer tube 2 in the opposite direction of the guiding cone head 11, so that the outer tube 2 pushes the outer supporting jaw 32 to open through the first pushing rod 31, and the silicone sheet 35 at the end of the outer supporting jaw 32 contacts the vagina. While the outer supporting jaw 32 opens, the second pushing rod 33 drives the holding jaw 34 to open, pushing the device toward the cervical canal so that the holding jaw 34 wraps the cervical canal. Pull the outer tube 2 again to fix the silicone sheet 35 at the end of the outer supporting jaw 32 to the vagina, and the installation of the device is completed.

[0033] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0034] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent modifications made according to the scope of the claims of the present application are within the scope of protection of the claims of the present application.
