Description

Technical Field

[0001] The present invention relates to a medical endometriosis guiding device and a using method thereof, belonging to the field of medical devices. Background Art

[0002] When treating endometriosis through laparoscopy, a uterine manipulator is usually required. The uterine manipulator is mechanically fixed to the cervix or the uterine cavity, can stably position the uterus, and jacks up the uterus by adjusting the angle, so as to fully expose deep lesion areas such as the posterior fornix of the vagina and the rectouterine pouch. This is particularly important for treating deeply infiltrating endometriosis (DIE).

[0003] Currently, when using the existing uterine manipulator, the length of its guiding rod is mostly set according to medical imaging data. However, improper setting of the guiding rod length may cause perforation or injury. Although there are guiding rods made of materials such as silicone on the market to avoid damage to the patient's organs, in actual use, the guiding rod often needs to be abutted against the patient's uterine cavity to provide support and fixation during the operation to avoid organ shaking. Whether the medical staff provides sufficient support and fixation effect can often only be judged by experience. If the operation can be performed during the operation, no adjustment will be made. If too much pressure is applied to the patient's uterine cavity, after the patient wakes up from anesthesia, due to the large pressure applied to the uterine cavity for a long time during the operation, it is very likely to cause discomfort to the patient. Therefore, it is necessary to improve it. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems in the background art, and provide a medical endometriosis guiding device and a using method thereof.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A medical endometriosis guiding device includes a guiding rod, a connecting pipe, a uterine lifting cup and a connecting ring; the uterine lifting cup is connected to one end of the connecting pipe by a thread; the guiding rod is located inside the connecting pipe and is slidably matched with the connecting pipe; threads are provided on the outer side of the guiding rod and on the outer side of the end of the connecting pipe away from the uterine lifting cup, and the connecting ring is connected to the guiding rod and the connecting pipe by threads.

[0007] A using method of a medical endometriosis guiding device, the using method includes the following steps:

[0008] Step 1: Connect the uterine lifting cup to the connecting pipe, then place the guiding rod into the connecting pipe, connect the inflator, then adjust the length of the guiding rod exposed outside the uterine lifting cup according to the uterine cavity depth obtained from the medical film, and finally fix the guiding rod and the connecting pipe through the connecting ring;

[0009] Step 2: Place the airbag and the uterine lifting cup into the patient's body;

[0010] Step 3: Connect the channels to the intake duct Ⅲ and the intake duct Ⅳ respectively, so as to pressurize and expand the uterine cavity fixing airbag and the vaginal fixing airbag through the inflator.

[0011] Step 4: During the laparoscopic surgery, the channels can be controlled to be connected to the intake duct Ⅰ or the intake duct Ⅱ, and air is inflated through the inflator to provide sufficient support for the organs by the airbag.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention can not only adjust the internal pressure of the airbag during the operation to adjust the support and fixation effects of the airbag on the patient's organs, but also can prompt the medical staff whether the fixing airbag is inflated through the limiting device to avoid situations such as forgetting.

The air pressure of each airbag is controlled through the channel 110, the air inlet channel I 15, the air inlet channel II 16, the air inlet channel III 114 and the air inlet channel IV 115. The partition pad 12 is made of rubber, so that the air pressure of the end part and the outer circular side of the airbag 11 can be controlled respectively.

[0022] A sealing gasket 18 is provided between the rotating rod 19 and the rod body 13. A through hole communicating with the channel 110 is provided on the sealing gasket 18.

[0023] An air inlet channel III 114 communicating with the vaginal fixing airbag 14 provided on the outer side of the connecting pipe 2 and an air inlet channel IV 115 communicating with the uterine cavity fixing airbag 21 provided on the outer side of the rod body 13 are also provided on the rod body 13. The connecting pipe 2 is provided with a hole communicating the vaginal fixing airbag 14 and the air inlet channel IV 115.

[0024] The center lines of the air inlet channel I 15, the air inlet channel II 16, the air inlet channel III 114 and the air inlet channel IV 115 are at equal distances from the center line of the rod body 13; the channel 110 also communicates with the air inlet channel III 114 or the air inlet channel IV 115. Ensure that the rotating rod 19 can communicate with the air inlet channel I 15, the air inlet channel II 16, the air inlet channel III 114 and the air inlet channel IV 115 respectively after rotation.

[0025] Limit devices are provided in both the air inlet channel III 114 and the air inlet channel IV 115.

[0026] Each of the limiting devices includes a movable rod 116 and a spring 117; the movable rod 116 is perpendicular to the center line of the intake passage III 114 or the intake passage IV 115; one end of the movable rod 116 on each limiting device passes through the inner wall of the intake passage III 114 or the intake passage IV 115 and is embedded in the card slot on the outer cylindrical surface of the shaft rod 17, and the other end of the movable rod 116 is fixedly connected with a piston 113, and the other end of the piston 113 passes through the inner wall of the intake passage III 114 or the intake passage IV 115 and is arranged outside the rod body 13; one end of the spring 117 is fixedly connected to the outer cylindrical surface of the movable rod 116, and the other end of the spring 117 is fixed to the inner wall of the intake passage III 114 or the intake passage IV 115. It is judged whether the corresponding fixed airbag has been inflated and pressurized by whether the piston 113 is exposed outside the rod body 13, so as to avoid forgetting the operation, resulting in the slippage of the uterine lifting cup 3 during the operation and affecting the operation.

[0027] When the movable rod 116 is embedded in the card slot on the shaft rod 17, the spring 117 is in its original length state.

[0028] A plurality of markers I 119 corresponding to the positions of the intake passage I 15, the intake passage II 16, the intake passage III 114 and the intake passage IV 115 respectively are arranged on the outer cylindrical surface of the rod body 13; a marker II 118 corresponding to the position of the passage 110 is arranged on the outer cylindrical surface of the rotating rod 19. It is convenient to identify the position where the passage 110 is located.

[0029] A method for using a medical endometriosis guiding device, the method comprising the following steps:

[0030] Step 1: Connect the uterine lifting cup 3 to the connecting pipe 2, then place the guiding rod 1 into the connecting pipe 2, connect the inflator 112, then adjust the length of the guiding rod 1 exposed outside the uterine lifting cup 3 according to the uterine cavity depth obtained from the medical film, and finally fix the guiding rod 1 and the connecting pipe 2 through the connecting ring 4;

[0031] Step 2: Place the airbag 11 and the uterine lifting cup 3 into the patient's body;

[0032] Step 3: Connect the passage 110 with the intake passage III 114 and the intake passage IV 115 respectively, so as to pressurize and expand the uterine cavity fixing airbag 21 and the vaginal fixing airbag 14 through the inflator 112;

[0033] Step 4: During the laparoscopic surgery, it is possible to control the connection between the passage 110 and the intake passage I 15 or the intake passage II 16, and inflate through the inflator 112 to make the airbag 11 provide sufficient support for the organ.

[0034] The working principle of the present invention is as follows: Connect the uterine lifting cup 3 to the connecting pipe 2, then place the guiding rod 1 into the connecting pipe 2 and connect the inflator 112. Subsequently, adjust the length of the guiding rod 1 exposed outside the uterine lifting cup 3 according to the uterine cavity depth obtained from the medical film. Finally, fix the guiding rod 1 and the connecting pipe 2 through the connecting ring 4.

[0035] Place the airbag 11 and the uterine lifting cup 3 into the patient's body. The airbag 11 wraps around the end of the rod body 13, which can effectively prevent the rod body 13 from stabbing the patient's organs.

[0036] Connect the channel 110 to the air inlet passage III 114 and the air inlet passage IV 115 respectively, so as to pressurize and expand the uterine cavity fixing airbag 21 and the vaginal fixing airbag 14 through the inflator 112. When the rotating shaft 17 rotates to connect the channel 110 with the air inlet passage III 114 or the air inlet passage IV 115, the movable rod 116 in the air inlet passage III 114 or the air inlet passage IV 115 is embedded in the card slot on the outer circular surface of the shaft rod 17 under the elastic force of the spring 117. The piston 113 is located inside the rod body 13. If air is not inflated into the uterine cavity fixing airbag 21 and the vaginal fixing airbag 14, and the movable rod 116 cannot be disengaged from the card slot, the medical staff are prohibited from rotating. After inflating the corresponding fixing airbag through the inflator 112, the pressure in the air inlet passage III 114 or the air inlet passage IV 115 increases as the pressure in the fixing airbag increases. After the pressure in the air inlet passage III 114 or the air inlet passage IV 115 increases, the air pressure pushes the piston 113 to move outside the rod body 13, thereby driving the movable rod 116 to disengage from the card slot. At the same time, the piston 113 is exposed outside the rod body 13. Only at this time can the rotating rod 19 be rotated to prevent the medical staff from forgetting to inflate the uterine cavity fixing airbag 21 and the vaginal fixing airbag 14, and the uterine cavity fixing airbag 21 and the vaginal fixing airbag 14 are placed in the patient's body and are not easy to detect, resulting in the device slipping out or disengaging during the operation, affecting the operation.

[0037] During the laparoscopic surgery, the rotating rod 19 can be rotated to control the connection between the channel 110 and the air inlet passage I 15 or the air inlet passage II 16, and air is inflated into it through the inflator 112 to make the airbag 11 provide sufficient support for the organ.

[0038] When the channel 110 is connected to the air inlet passage I 15, the pressure at the end of the airbag 11 can be controlled by inflating and deflating to ensure the fixation of the uterus and provide sufficient supporting force for the lesion site.

[0039] When the channel 110 is connected to the air inlet passage II 16, after inflating air into it, the side surface (outer circular surface) of the airbag 11 expands, which can provide a larger supporting surface, thereby ensuring that the lesion site on the surface of the uterus and its surrounding areas can be fully exposed, providing a better vision for the doctor.
