Description
Technical Field
[0001] The invention relates to the technical field of laparoscopic surgical instruments, and in particular to a device for controlling the movement of the uterus through the abdomen and closing the vagina during laparoscopic cervical cancer surgery. Background Art
[0002] Laparoscopic surgery is a minimally invasive surgical technique that involves making several small holes in the abdomen, inserting a laparoscope and other surgical instruments, and examining, treating and repairing the abdominal cavity.
[0003] During existing cervical cancer surgeries, when the uterus is removed, a uterine manipulator is often used to control the position of the uterus, so that the doctor can remove tissue adhered to the outside of the uterus. The existing uterine manipulator is roughly a rod structure, which is inserted through the female vagina, passes through the cervix to reach the inside of the vagina, and the position of the uterus is controlled by swinging the uterine manipulator reserved at one end outside the human body.
[0004] The problem with the existing uterine manipulator during use is that when it controls the movement of the uterus, the uterine manipulator keeps pressing on the cervical cancer lesions, and constantly squeezes and rubs the cervical cancer lesions, causing cervical cancer cells to enter the microvessels and lymphatic vessels, resulting in tiny diffusion and metastasis. This is also the reason why the probability of recurrence in existing cervical cancer surgeries using laparoscopic surgery is higher than that of direct open abdominal cervical cancer surgery. The incision in the abdomen of existing open abdominal cervical cancer surgeries is much larger than the opening size of laparoscopic surgery, causing greater damage to the human body. Based on the above situation, it is necessary to design a laparoscopic cervical cancer surgery through the abdomen uterine movement control and vaginal closure device to solve the above problems. Summary of the invention
[0005] The present invention provides a device for controlling the movement of the uterus and closing the vagina through the abdomen during laparoscopic cervical cancer surgery.

DETAILED DESCRIPTION
[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.
[0034] In order to enable those skilled in the art to understand the innovation of the present invention, the prior art involved in the present invention is first introduced. Fig. 9 , is a schematic diagram of the uterus 17 of the human body and other connected tissue structures. The front end of the uterus 17 is connected to the vagina 12 through the cervix 11, and the two sides of the uterus 17 are connected to the ovaries 14 through the fallopian tubes 13. It should be further explained that the uterus 17 is connected to other tissues that are not drawn in the figure, such as the round ligament: the round ligament connects the front and upper part of the uterus 17 and the pelvic side wall, and its main function is to maintain the forward position of the uterus 17; the broad ligament: the broad ligament is the peritoneal fold between the two sides of the uterus 17 and the pelvic side wall, which contains blood vessels, nerves, and the like. The main ligament is also called the transverse ligament of the uterine part 17 neck, which connects the uterine part 17 neck and the pelvic side wall. Its main function is to fix the position of the uterine part 17 neck; parauterine tissue: parauterine tissue includes connective tissue, blood vessels and nerves around the uterine part 17. Of course, there are other tissues, which are not elaborated here. When the uterine part 17 is removed, the first step is to cut and separate the tissues connected to the uterine part 17 (except the vagina 12 and the cervix 11) from the uterine part 17 so that the uterine part 17 is isolated inside the abdominal cavity, such as Fig.10 In the state shown, in the second step, the cutting device is used again to cut at the connection position between the cervix 11 and the vagina 12, so that the uterine part 17 is completely cut, and the cut uterine part 17 is transferred through the instrument from the minimally invasive channel in the abdomen to a storage bag in the abdominal cavity, and then the uterine part 17 is taken out from the minimally invasive channel (the minimally invasive channel is small, and generally it needs to be gradually divided into small pieces during the removal process), thereby completing the uterine part 17 removal operation.
[0035] During the above-mentioned removal of the uterine part 17, since there are many tissues connected around the uterine part 17, a better field of vision can be obtained during the cutting process. For example, the bottom of the uterine part 17 needs to be pulled up by the uterus in order to see the tissue below with the help of a laparoscope. Therefore, the position of the uterine part 17 needs to be controlled and moved with the help of a uterine manipulator, so that medical personnel can peel off the tissue around the uterine part 17. The problem with the existing uterine manipulator is that since the rod-shaped uterine manipulator needs to pass through the cervix 11 from the vagina 12 of the human body into the interior of the uterus, when controlling the movement of the uterus, the cancer tissue of the cervix 11 will be squeezed and rubbed, which may easily cause the cancer cells of the cervix 11 to enter the microvessels and lymphatic vessels, resulting in tiny diffusion and metastasis. At the same time, when cutting the connection between the cervix 11 and the vagina 12, there is no good closing device to seal the stump of the vagina 12, which may easily cause tumor cells exposed to the vagina 12 and the external opening of the cervix 11 to be artificially brought into the abdominal cavity, causing later recurrence.
[0036] Based on the above problems, the present invention provides a laparoscopic cervical cancer surgery transabdominal uterine part 17 movement control and vagina 12 closing device to solve the above problems. The main implementation method is to control the position of the uterus by puncturing the abdomen with a lifting rod 1, and at the same time, a restraining part is set on the lifting rod 1 to achieve the closure of the residual end of the vagina 12 when the vagina 12 is separated from the uterus.
[0037] Specifically, refer to Figure 1 and Fig.11 The present invention discloses a laparoscopic cervical cancer surgery transabdominal uterine part 17 movement control and vagina 12 closing device, including a lifting rod 1 that can be stabilized with the surface of the uterine part 17 through abdominal puncture to achieve control of the movement of the uterine part 17, and a suction cup 103 that can adsorb the surface of the uterine part 17 is provided at one end of the lifting rod 1 entering the abdomen. The uterine part 17 movement control and vagina 12 closing device also includes a negative pressure device 2 that can generate an adsorption force on the suction cup 103 at the end of the lifting rod 1. A channel is also provided inside the lifting rod 1, and the channel is used for a restraining member that can form a sleeve 10 to pass through, and the sleeve 10 is used to close the residual end of the vagina 12.
[0038] Furthermore, the restraining member may be an air suction pipe 3 for connecting the negative pressure device 2 and the suction cup 103 , and the size of the formed restraining sleeve 10 may be controlled by pumping the air suction pipe 3 passing through the channel on the lifting rod 1 .
[0039] When the restraining member is the exhaust pipe 3, the present invention provides two embodiments, which are described in detail below.
[0040] First reference Figure 2 and Figure 3, which is a first embodiment of the lifting rod 1 of the present invention, a double channel is opened inside the lifting rod 1 (the lifting rod 1 includes a rod body 101 and a handle 102 mentioned below, and the channel is opened inside the rod body 101), one end of the exhaust pipe 3 passes through a channel from bottom to top (up and down refers to the orientation of the attached figure, which can also be specifically described as from the end punctured into the abdomen of the human body to the end left outside the human body) and is connected to the negative pressure device 2, the other end of the exhaust pipe 3 also passes through the lifting rod 1 from bottom to top, and then a plugging head 8 is used to secure the end to the channel, (the specific plugging head 8 preferably adopts a detachable connection Sealing method, this connection method can adopt the existing snap connection, threaded connection or bonding method, which will not be further elaborated here), thereby forming a U-shaped interlaced shape, and the suction cup 103 corresponds to the bottom of the U-shaped exhaust pipe 3, which is also the lower end of the lifting rod 1. When in use, by attaching the suction cup 103 to the uterine part 17 of the human body, starting the negative pressure device 2, the suction cup 103 can generate negative pressure and be firmly fixed on the uterine part 17. By controlling the movement of the lifting rod 1, the position of the uterine part 17 can be controlled. It should be noted that in order to avoid the suction cup 103 from shaking too much relative to the lifting rod 1, When the lifting rod 1 is controlled to move, the side of the suction tube 3 connected to the negative pressure device 2 can be wrapped around the handle to prevent the suction tube 3 inside the channel from sliding. In this way, the suction cup 103 shakes during the movement of the position of the uterine part 17, causing the uterine part 17 to fall off from the suction cup 103. By adjusting the position of the uterine part 17, the doctor can have a good field of vision to peel and divide the tissues connected around the uterine part 17. When the first step of the uterine part 17 resection is completed (the first step refers to the separation of all connected tissues except the vagina 12 and the cervix 11), at this time, the passage The suction pipe 3 is transported into the interior of the channel, and the suction pipe 3 forms a sheath 10 at the bottom of the lifting rod 1. The sheath 10 is used to tighten the connection between the cervix 11 and the vagina 12 (this position after cutting can also be called the stump of the vagina 12), so that the connection can be closed. Then, the uterus 17 is separated from the vagina 12 with a cutting knife, and then the entire removed uterus 17 is transferred to a storage bag, and the sheath 10 can be loosened to prevent tumor cells exposed to the vagina 12 and the external opening of the cervix 11 from being artificially brought into the abdominal cavity, causing a later recurrence. Specifically, in the process of closing the stump of the vagina 12 by the sheath 10, refer to Fig.11 and Fig.12 ,exist Fig.11 In the process, the suction tube 3 is pushed to move inside the lifting rod 1 (the pushing direction of the suction tube 3 is the direction of F1 in the figure), so that a sleeve 10 can be formed on the abdomen of the human body and corresponding to the bottom of the lifting rod 1. When the size of the sleeve 10 is large enough to accommodate the uterus 17, the sleeve 10 is moved in the direction of F2 to form Fig.12 The sleeve 10 is at the connection between the cervix 11 and the vagina 12. At this time, the suction tube 3 is pulled toward the outside of the lifting rod 1 (such as Fig.12 In the direction of F3 in the middle, the sheath 10 can be tightened to seal the connection between the cervix 11 and the vagina 12 in the figure, which is called the tying part 15 for the convenience of description. Fig.12 At the marked position, due to the closure of the binding portion 15, the uterus is in a closed state at this time, and a cutting instrument can be used to cut the connection between the vagina 12 and the cervix 11. For the convenience of description, the cutting position is named as the dividing portion 16. Fig.12 Mark the location.
[0041] For further reference, Figure 4 and Figure 5 , is a structural schematic diagram of the second embodiment of the lifting rod 1 provided by the present invention. The difference between the second embodiment and the first embodiment is that there is only one channel inside the lifting rod 1, that is, a single channel. After one end of the exhaust pipe 3 is fixed to the bottom of the lifting rod 1, the end of the exhaust pipe 3 connected to the negative pressure device 2 is passed through the channel from bottom to top and connected to the negative pressure device 2. In this way, the same effect as the first embodiment can be achieved. The process of use is similar to that of the first embodiment and will not be elaborated here.
[0042] For further reference, Figure 6 and Figure 7 Schematic diagram of the structure of the third embodiment of the lifting rod 1 provided by the present invention. In this embodiment, the binding member adopts the binding line 9 to achieve the closure of the bundling part 15, and the exhaust pipe 3 is only used as a pipeline that can provide negative pressure. The connection relationship between it and the lifting rod 1 is preferably fixed to ensure that the suction cup 103 at the bottom of the exhaust pipe 3 does not shake. Specifically, when the binding line 9 is used as the binding member, the interior of the lifting rod 1 is a double channel, and the two free ends of the binding line 9 pass through a channel from bottom to top respectively to form a U-shape. By pumping the two free ends of the binding line 9, the expansion and contraction of the binding sleeve can also be achieved. Fig.13 As shown, by pulling the free ends of the two binding lines 9 ( Fig.13 In the direction of F3 in the middle), the bundling of the bundling part 15 is realized.
[0043] Furthermore, in order to ensure the stability of the adsorption force of the suction cup 103 in the above three embodiments, Figure 1 and Fig.14As shown, the negative pressure device 2 includes a negative pressure driving device 7 (such as a vacuum pump or other device capable of generating negative pressure) and a controller 6. The controller 6 controls the operation of the negative pressure driving device 7 so that the vacuum pipe 3 at its input end (the input end and output end in this article refer to the flow direction of the airflow) generates negative pressure, thereby causing the suction cup 103 at the input end of the vacuum pipe 3 to generate adsorption force. A negative pressure sensor 4 is also provided on the vacuum pipe 3. The negative pressure sensor 4 is used to monitor the negative pressure in the vacuum pipe 3, thereby feeding back negative pressure information to the controller 6. The controller 6 controls the operation of the vacuum pump according to the negative pressure in the vacuum pipe 3 fed back by the negative pressure sensor 4, so that the negative pressure value in the vacuum pipe 3 is stabilized within a preset value range, thereby ensuring the stability of the adsorption force of the suction cup 103.
[0044] Furthermore, in order to facilitate personnel to control the position of the uterus part 17 by holding the lifting rod 1, a handle 102 is provided at the upper end of the lifting rod 1, and a recessed groove 104 cooperating with the restraining member is also provided on the handle 102, that is, when the bundling part 15 needs to be closed, the restraining member is wrapped around the recessed groove 104, one circle or half a circle, and the restraining line 9 can be prevented from sliding by holding it tightly with the hand. It needs to be further explained that when the above-mentioned vacuum tube 3 is used as a restraining member, in order to prevent the suction cup 103 from shaking during the process of controlling the movement of the uterus, the end of the vacuum tube 3 connected to the negative pressure device 2 needs to be fixed to prevent the suction cup 103 from shaking, and the vacuum tube 3 can also be wrapped around the handle to prevent the suction cup 103 from shaking. The concave groove 104 of 102 is used to achieve stability, so as to avoid the exhaust pipe 3 from bending too much, which may cause blockage and affect the adsorption force of the suction cup 103. It should be further explained that in the process of closing the vagina 12 (that is, when the bundling part 15 is tied), in order to better facilitate the uterus 17 to pass through the sheath 10 and make the sheath 10 align with the position of the bundling part 15, two lifting rods 1 can be used, one for controlling the movement of the uterus 17 and the other for forming the sheath 10. When used, the lifting rod 1 is consistent with the method of entering the abdominal cavity with a laparoscope, that is, both are penetrated into the abdominal cavity through a minimally invasive channel opened in the abdomen. The exhaust pipe 3 and the negative pressure device 2 are also arranged to be detachably connected, such as Figure 1 In the figure, the connector 5 is used to connect with the exhaust pipe 3 , and the negative pressure sensor 4 can be arranged on the connector 5 .
[0045] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
