Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a device for fallopian tube recanalization, and specifically provides a transperitoneal fallopian tube recanalization device. Background Art

[0002] In clinic, tubal obstruction is an important cause of infertility, and tubal obstruction may be caused by ligation or by blockage of the isthmus or ampulla of the tubal caused by pathological changes. Currently, laparoscopic surgery is used in clinic. Under the visual state of laparoscopy, the operation channel is used to enter the abdominal cavity to remove the blocked part of the tubal. After the removal, the tubal is cut off at both ends, and the two unblocked tubal sections are sutured and restored to ensure the patient's conception and the movement of the fertilized egg after conception.

[0003] The fallopian tube is soft and thin. The operation of connecting two sections of the fallopian tube is very cumbersome and not smooth. If the connection is not good, the suture will be completed. Even after suturing, the junction of the fallopian tube is prone to inward scar growth. The inward scar will cause the tube to narrow at the suture of the fallopian tube. Although the tube is restored, there is still a problem of poor passage of the fertilized egg, which reduces the probability of normal pregnancy after the operation.

[0004] Therefore, there is a need for an instrument that can effectively complete the recanalization of two cut fallopian tubes. The present invention provides a transperitoneal fallopian tube recanalization instrument. Summary of the invention

[0005] After the fallopian tube is cut, the fallopian tube will collapse due to its softness, which requires a lot of effort for medical staff to dock it. In addition, it is particularly easy to cause endogenous scars due to poor docking, which will reduce the chance of normal pregnancy after surgery. The present invention uses a double support structure sent through the operating channel of a laparoscope to support two sections of the fallopian tube; and a structure for docking the double support structure is provided to support the docking and state maintenance of the latter two support structures, so as to ensure the effective docking of the two sections of the fallopian tube. After docking, the suturing operation is completed under the observation of the laparoscope.

[0006] A transperitoneal fallopian tube recanalization device, comprising:

[0007] There are two supporting structures, namely the first supporting structure and the second supporting structure; used to support two sections of fallopian tubes, each supporting structure includes

[0008] Balloon part;

[0009] The support part is arranged outside the balloon part, and the balloon part props up the support part and then withdraws, and the support part maintains the propped-up state, and the support part is made of absorbable material; or the support part changes with the size of the balloon part;

[0010] An inflation tube connected to the balloon part and used to inflate the balloon part, and a terminal end of the inflation tube is arranged outside the body and connected to the inflation structure;

[0011] Two delivery tubes are provided, one delivery tube is provided with a support structure, the support structure is closely attached to the inner wall of the delivery tube, and the positions of the support structure and the delivery tube remain unchanged without external force; the filling tube on the support structure is introduced to the outside of the delivery tube through the delivery tube; the support structure is delivered to the two cut-off fallopian tubes through the delivery tube through the operation channel of the laparoscope or other separate operation channels;

[0012] Two push-out structures are provided, one push-out structure is provided in one conveying pipe, a first end of the push-out structure is provided in the conveying pipe, and a second end of the push-out structure is provided outside the conveying pipe, and the push-out structure pushes the support structure in the conveying pipe out of the conveying pipe;

[0013] The fallopian tube at the cut point is divided into the first section of the fallopian tube away from the uterus and the second section of the fallopian tube connected to the uterus.

[0014] Among them, a push-out structure pushes the first support structure out of the delivery tube, and then withdraws the delivery tube, inflates the balloon part of the first support structure through the inflation tube, drives the support part to expand, expands the first section of the fallopian tube, and then deflates and withdraws the balloon part, the delivery tube and the push-out structure. Then repeat the above action to send the second support structure into the second section of the fallopian tube to expand the second section of the fallopian tube.

[0015] Furthermore, a docking structure is provided, wherein the supporting part of the first supporting structure is the first supporting part, and the supporting part of the second supporting structure is the second supporting part; the docking structure includes a pulling wire provided on the first supporting part and a first threading hole of the second supporting part, the pulling wire changes direction by passing through the threading hole, and the movement of the end of the pulling wire drives the threading hole to move toward the supporting part of the first supporting structure until the supporting parts of the first supporting structure and the second supporting structure are docked. Alternatively, the setting mode of the pulling wire in the first supporting part and the second supporting part can be adjusted.

[0016] Steps:

[0017] The cut fallopian tube is divided into the first fallopian tube away from the uterus and the second fallopian tube connected to the uterus. The operation is performed under laparoscopic observation.

[0018] Support of the first section of the fallopian tube: under the observation and guidance of the laparoscope, the delivery tube provided with the first support structure is led into the first section of the fallopian tube, and then under the observation of the laparoscope, the delivery tube stops after entering a position 1-3 mm away from the edge of the first section of the fallopian tube, and the first support structure is pushed out from the delivery tube into the first section of the fallopian tube by using the push-out structure, and it is ensured that the first support structure completely enters the first section of the fallopian tube; the balloon part of the first support structure is inflated by using the inflation tube, and the first section of the fallopian tube is supported by the propped-up first support structure, and after being propped up, the support part itself or under the action of the balloon maintains the propped-up state of the fallopian tube;

[0019] Support of the second fallopian tube: under the observation and guidance of the laparoscope, the delivery tube provided with the second support structure is led into the second fallopian tube, and then under the observation of the laparoscope, the delivery tube stops after entering a position 1-3 mm away from the edge of the second fallopian tube, and the second support structure is pushed out from the delivery tube into the first fallopian tube by using the push-out structure, and it is ensured that the second support structure completely enters the second fallopian tube; the balloon part of the second support structure is inflated by using the inflation tube, and the second fallopian tube is supported by the propped-up second support structure; after being propped up, the support part itself or under the action of the balloon maintains the propped-up state of the fallopian tube;

[0020] Docking of two sections of fallopian tubes: Under laparoscope observation, the pulling wire is passed through the first threading hole and the second threading hole in turn, and the pulling wire is pulled to control the first support structure to move toward the second support structure. During the process, the direction can be controlled and adjusted by the laparoscope operating instrument to achieve docking of the first support structure and the second support structure; at the same time, the first section of the fallopian tube supported by the two is docked with the second section of the fallopian tube.

[0021] Suturing of the fallopian tube and withdrawal of the traction line: Under laparoscopic observation, the docked fallopian tubes are sutured, and finally the traction line is set in position. The traction line is separated from the supporting part by cutting, and the fallopian tube is completely sutured after separation.

[0022] Beneficial effects of the present invention:

[0023] The method of extending the two support structures into the two disconnected fallopian tubes through the laparoscopic operating channel or the transperitoneal operating channel can ensure that the placement of the support structures is smoother and has a certain degree of continuity.

[0024] The setting of the two supporting structures can ensure that the two sections of the fallopian tube are propped up, ensure the correspondence of the edges during suturing, and ultimately ensure the suturing effect, avoiding the problem of endogenous scarring caused by edge mismatch.

[0025] By setting the support structure at a distance of 1-3 mm from the edge of the fallopian tube, it can be ensured that the two sections of the fallopian tube are effectively docked and overlapped in a small range when the two support structures are docked. This overlap after docking can effectively reduce the difficulty of suturing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] Example 1

[0035] refer to Figure 1-7 , a transperitoneal fallopian tube recanalization device, comprising,

[0036] There are two supporting structures, namely a first supporting structure and a second supporting structure; they are used to support two sections of fallopian tubes, and each supporting structure includes a balloon part 14; the supporting part is arranged on the outside of the balloon part 14, and the balloon part 14 props up the supporting part and then withdraws, and the supporting part is made of absorbable material; an inflation tube 15 is connected to the balloon part 14 and is used to inflate the balloon part 14, and the end of the inflation tube 15 is arranged outside the body and connected to the inflation structure; the setting method of the balloon support supporting part can be selected to adjust the diameter of the supporting part according to the specific size of the patient's fallopian tube.

[0037] Two delivery tubes 2 are provided, one delivery tube 2 is provided with a support structure, the support structure is closely attached to the inner wall of the delivery tube 2, and the position of the support structure and the delivery tube 2 remains unchanged without external force; the filling tube 15 on the support structure is introduced to the outside of the delivery tube 2 through the delivery tube 2; the support structure is delivered to the two cut-off fallopian tubes through the delivery tube 2 through the operation channel of the laparoscope or other separate operation channels;

[0038] Two push-out structures are provided, one push-out structure is provided in one delivery pipe 2, a first end of the push-out structure is provided in the delivery pipe 2, and a second end is provided outside the delivery pipe 2, and the push-out structure pushes the support structure in the delivery pipe 2 out of the delivery pipe 2;

[0039] The fallopian tube at the cut portion is divided into a first fallopian tube section 51 away from the uterus and a second fallopian tube section 52 connected to the uterus.

[0040] Among them, a push-out structure pushes the first support structure out of the delivery tube 2, and after pushing out, the delivery tube 2 is withdrawn, and the balloon part 14 of the first support structure is inflated through the inflation tube 15, driving the support part to open, and the first section of the fallopian tube 51 is opened. When the support part is a structure that maintains the propped state after deflation, the balloon part 14 is deflated after opening, and the balloon part 14, the delivery tube 2 and the push-out structure are withdrawn; or when the support part changes with the size of the balloon part 14, the balloon maintains the inflated state and remains in the first section of the fallopian tube 51 with the support part, and the delivery tube 2 and the push-out structure are withdrawn; the inflation tube 15 is retained outside the body after passing through the operation channel. Then repeat the above action to send the second support structure into the second section of the fallopian tube 52, and the second section of the fallopian tube 52 is opened. The edge of the supporting part of the first supporting structure is 1-3mm away from the edge of the first section of the fallopian tube 51; the edge of the supporting part of the second supporting structure is 1-3mm away from the edge of the second section of the fallopian tube 52; this setting idea can ensure that there is sufficient suturing area during subsequent docking, ensuring the smoothness of the docking and suturing operations.

[0041] When in use, the two support structures are extended into the two disconnected sections of fallopian tubes through the operating channel of the laparoscope or the operating channel corresponding to other openings of the abdominal cavity. Through the arrangement of the above two sets of delivery tubes 2 and their corresponding support structures and the push-out structure, one section of fallopian tube can correspond to one delivery tube 2, and the two do not interfere with each other. The entry path section of the delivery tube 2 through the abdominal cavity is simple, as long as the size requirements of the fallopian tube of the separated section can be met. In this way, the size requirements of each structure are small, so the size requirements are small, so the requirements for the preparation process are also lower. The entire surgical process is completed under the observation of the laparoscope, and other tools for steering and guiding the entry of the delivery tube 2 can be assisted, making the operation difficulty of the entire operation also smaller.

[0042] When the supporting part is made of absorbable material, the supporting part is a support with mesh holes. The supporting part of this arrangement remains in the fallopian tube after the operation is completed and completes self-absorption in the body.

[0043] refer to Figure 5 When the supporting part changes with the size of the balloon part 14, the supporting part is a mesh support or a plurality of supporting sheets 13 attached to the wall of the balloon part 14. When the supporting part is sutured to the last few stitches, the balloon part 14 is deflated, so that the supporting part with a smaller size is withdrawn from the fallopian tube through the unsutured small hole, because most of the area has been sutured, and the best small hole can also be sutured better under soft conditions.

[0044] In a more preferred embodiment, a docking structure is further provided, wherein the supporting part of the first supporting structure is the first supporting part 11, and the supporting part of the second supporting structure is the second supporting part 12; the docking structure includes a pull line 41 provided on the first supporting part 11 and a first threading hole 42 of the second supporting part 12, the pull line 41 passes through the threading hole to change direction, and the end of the pull line 41 moves to drive the threading hole to move toward the supporting part of the first supporting structure until the supporting parts of the first supporting structure and the second supporting structure are docked. Alternatively, the setting mode of the pull line 41 in the first supporting part 11 and the second supporting part 12 can be adjusted.

[0045] Alternatively, the pulling wire 41 is introduced into the body, and a second threading hole 43 is provided on the first supporting portion 11. The pulling wire 41 changes direction once through the first threading hole 42, and then changes direction for the second time through the second threading hole 43, and then is introduced into the body through the operation channel, and the pulling wire 41 is fixed after docking. By providing the second threading hole 43 on the first supporting portion 11, the relative distance between the first supporting portion 11 and the second supporting portion 12 can be ensured to be closer and more accurate.

[0046] In a more preferred embodiment, the first threading hole 42 and the second threading hole 43 are both strip holes, which can ensure the accuracy of the docking position during docking and avoid the distortion of the fallopian tube caused by poor docking. A plurality of first threading holes 42 and second threading holes 43 can be provided, and docking is performed according to the best docking position.

[0047] In a more preferred embodiment, the first support part 11 is provided with a plurality of inclined short plates 161 extending inwardly and arranged around the edge circumference, and absorbable biological glue is arranged on the inclined short plates 161; correspondingly, the second support part 12 is provided with a plurality of inclined short plates 162 extending outwardly and arranged around the edge circumference, and the inclined short plates 162 are arranged inside the inclined short plates 161 to complete docking, and the docking is maintained after the docking is completed by the biological glue. Finally, the outer diameter of the structure surrounded by the inclined short plates 161 and the inclined short plates 162 is smaller than the inner diameter of the corresponding support part body.

[0048] In a more preferred embodiment, the first supporting portion 11 is identical to the second supporting portion 12, an inclined short plate 161 is provided at one end of each supporting portion, and an inclined short plate 2 162 is provided at the second section, and the first supporting portion 11 and the second supporting portion 12 are in opposite directions in the conveying tube 2; this arrangement can ensure that after entering the fallopian tube section, the inclined short plate 1 161 and the inclined short plate 2 162 can be docked.

[0049] Alternatively, refer to Figure 3 and Figure 4 ; An inclined short plate 161 is provided at the first end of the first supporting portion 11, and an inclined short plate 2 162 is provided at the second end; and inclined short plates 2 162 are provided at both ends of the second supporting portion 12; when the first supporting portion 11 is arranged in the delivery tube 2, the inclined short plate 2 162 at the second end is close to the first insertion end of the delivery tube 2; this arrangement can utilize the structure of the inclined short plate 2 162 extending outward and tilted toward the center to guide the first supporting portion 11 into the fallopian tube segment, and in the case of the second supporting portion 12, short plate 2 can also guide it to effectively enter the fallopian tube segment, reducing the difficulty of entry.

[0050] A more specific implementation is: when only threading hole 1 is provided, threading hole 1 is provided on inclined short plate 161 or inclined short plate 2 162; when threading hole 1 and threading hole 2 are provided, threading holes are provided on inclined plate 1 and inclined plate 2; because the inclined plate has a certain degree of inclination, it is better to provide threading holes from above, the preparation process is simple, and the threading action will be easier. Of course, the edge holes of the edge of the supporting part itself can also be used as threading holes. This arrangement can reduce the number of specially provided threading holes, and the pulling wire 41 will be easier to be completely cleaned after use to prevent it from being left behind.

[0051] In a more preferred embodiment, the pulling wire 41 is configured as an absorbable wire. The absorbable configuration can ensure that if the pulling wire 41 is not completely removed after docking is completed, it will be absorbed in the body.

[0052] A more preferred embodiment is to provide an auxiliary docking structure, such as surgical forceps that enter the surgical site through two channels. After the fallopian tubes are found to be twisted during docking under laparoscopy, the two sections of the stretched fallopian tubes are clamped separately by the surgical forceps to separate the docked fallopian tubes; after separation, the two sections of the fallopian tubes are rotated to ensure that the two sections are docked, rotated and re-docked at the correct angle.

[0053] A more preferred embodiment is as follows: Figure 7 The ejection structure is provided with an ejection plate 32 and an ejection tube 31; the ejection plate 32 is arranged in the conveying tube 2, and the ejection plate 32 contacts the supporting structure to play an ejection role. The first end of the ejection tube 31 is connected to the ejection plate 32, and the second end is arranged on the outside of the conveying tube 2. The movement of the ejection tube 31 drives the ejection plate 32 to play a role.

[0054] The rear end of the inflation tube is connected to the inflation structure, which can be a syringe or an electric inflation structure. The rear end of the inflation tube 15 is connected to a connector with a one-way valve that allows air to enter. The connector is connected to the inflation structure to complete the inflation action, and the inflation state is maintained after the inflation structure is removed; deflation is performed after the connector is removed (not shown in the figure); the entire structural setting is simple and reasonable.

[0055] Steps:

[0056] The cut fallopian tube is divided into the first fallopian tube 51 away from the uterus and the second fallopian tube 52 connected to the uterus. The operation is performed under laparoscopic observation.

[0057] Support of the first section of the fallopian tube 51: under the observation and guidance of the laparoscope, the delivery tube 2 provided with the first support structure is led into the first section of the fallopian tube 51, and then under the observation of the laparoscope, the delivery tube 2 enters the position 1-3mm away from the edge of the first section of the fallopian tube 51 and stops, and the first support structure is pushed out from the delivery tube 2 into the first section of the fallopian tube 51 by the push-out structure, and it is ensured that the first support structure completely enters the first section of the fallopian tube 51. The first end of the first support structure close to the edge of the first section of the fallopian tube 51 is finally achieved. The distance between the end of the first end and the edge of the first section of the fallopian tube 51 is 1-3mm; the balloon part 14 of the first support structure is inflated by the inflation tube 15, and the first section of the fallopian tube 51 is supported by the propped-up first support structure. After being supported, the support part maintains the propped-up state of the fallopian tube, and the delivery tube 2 and the push-out structure are withdrawn from the body. When the first support structure is a structure that maintains the propped-up state, the balloon part 14 is withdrawn at the same time;

[0058] Support of the second section of the fallopian tube 52: under the observation and guidance of the laparoscope, the delivery tube 2 provided with the second support structure is led into the second section of the fallopian tube 52, and then under the observation of the laparoscope, the delivery tube 2 enters the position 1-3mm away from the edge of the second section of the fallopian tube 52 and stops, and the second support structure is pushed out from the delivery tube 2 into the first section of the fallopian tube 51 by the push-out structure, and it is ensured that the second support structure completely enters the second section of the fallopian tube 52, and the edge of the second section of the fallopian tube 52 is the first end of the second support structure, and finally the distance between the first end and the edge of the second fallopian tube is 1-3mm; the balloon part 14 of the second support structure is inflated by the inflation tube 15, and the second section of the fallopian tube 52 is supported by the propped-up second support structure; after the propping-up, the supporting part maintains the propping state of the fallopian tube, and the delivery tube 2 and the push-out structure are withdrawn from the body, and when the first support structure is a structure that maintains the propping state, the balloon part 14 is withdrawn at the same time;

[0059] Docking of two sections of fallopian tubes: Under laparoscope observation, the pulling wire 41 is passed through the first threading hole 42 and the second threading hole 43 in turn, and the pulling wire 41 is pulled to control the first support structure to move toward the second support structure. During the process, the direction can be controlled and adjusted by the laparoscope operating instrument to achieve docking of the first support structure and the second support structure; at the same time, the first section of the fallopian tube 51 supported by the two and the second section of the fallopian tube 52 are docked.

[0060] Suturing the fallopian tube and withdrawing the traction line 41: Under laparoscope observation, suture the docked fallopian tubes, and finally suture the traction line 41 setting position, separate the traction line 41 from the support part by cutting, and complete the full suture of the fallopian tube after separation. When the support part is an absorbable structure that maintains the propped-up state, the support part is retained in the fallopian tube after complete suture; when the support part changes with the size of the balloon part 14, keep a few stitches without suture, keep a non-sutured opening, deflate the balloon part 14, and withdraw the balloon and the support part at the same time through the non-sutured opening.

[0061] Example 2

[0062] A transperitoneal fallopian tube recanalization system includes the fallopian tube recanalization device and a laparoscopic system according to Example 1; it should be noted that the cut fallopian tube is divided into a first fallopian tube 51 away from the uterus and a second fallopian tube 52 connected to the uterus.

[0063] The system also includes:

[0064] Delivery tube 2 placement unit: under laparoscopic observation, control the delivery tube 2 to enter the fallopian tube;

[0065] Support structure insertion unit: control the pushing structure to push the first support structure from the delivery tube 2 into the first section of the fallopian tube 51, and ensure that the first support structure completely enters the first section of the fallopian tube 51; then control the delivery tube 2 to withdraw from the fallopian tube, and then control the filling structure to deliver filling material to the filling tube 15, and the filling material is delivered to the balloon part 14 of the first support structure. The balloon part 14 is inflated and drives the supporting part of the first support structure to be propped up at the same time, and then the first section of the fallopian tube 51 is supported by the first support structure; the support structure insertion unit delivers the supporting part of the second support structure into the second section of the fallopian tube 52 according to the same steps, and uses the inflated supporting part to support the second section of the fallopian tube 52.

[0066] Withdrawal unit: when the supporting part maintains a propped-up state by itself, after the supporting parts of the first supporting structure and the second supporting structure are supported in the corresponding fallopian tube, the delivery tube 2, the pushing structure and the balloon part 14 are controlled to be withdrawn from the body; when the supporting part is maintained in a propped-up state by the balloon part 14, after the supporting part props up the fallopian tube, the delivery tube 2 and the pushing structure are controlled to be withdrawn from the body, and under the condition that the suture is basically completed with an unsutured opening, the balloon part 14 and the supporting part are controlled to be withdrawn from the body; respectively, the two supporting structures are acted upon;

[0067] Fallopian tube docking unit: controls the pulling wire 41 so that the two supporting parts are close to each other and docked.

[0068] The fallopian tube suturing unit controls the suturing instrument introduced through the laparoscope to complete the suturing of the docked fallopian tubes, and the corresponding supporting part is maintained in a propped-up state by the balloon part 14, and controls the unsutured opening during the suturing process, and the suturing is completed after the withdrawal unit withdraws the balloon part 14 and the supporting part;

[0069] A more preferred implementation is: under laparoscope observation, the support structure insertion unit controls the delivery tube 2 to stop after it reaches a position 1-3 mm away from the edge of the fallopian tube; the edge of the fallopian tube is the first end of the support structure, and the support structure insertion unit controls the pushing structure to keep the first end of the support structure 1-3 mm away from the edge of the fallopian tube; the arrangement of the above units can mainly ensure that the end of the support structure is at a certain distance from the edge of the fallopian tube after it is inserted and inflated, so that it can be effectively docked during docking, leaving an overlapping suture area to ensure the suture effect.
