Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a flexible supporting suture device for cervical laceration. Background Art

[0002] Cervical laceration is a tear caused by the expansion of the cervix beyond its expansion limit during normal delivery. Currently, it is usually necessary to perform cervical suture to suture the laceration after the normal delivery to avoid postpartum hemorrhage, infection, and possible cervical insufficiency in the future. During the cervical suture, the doctor needs to use a set of vaginal retractors to open the vagina so that the position of the cervix that needs to be sutured is fully exposed. Then the doctor sutures the torn part of the patient's cervix with a suturer combined with visual or endoscopy. However, when using vaginal retractors to open the patient's vagina to expose the part of the cervix to be sutured, the vaginal retractors are made of hard material and cause great damage to the inner wall of the vagina, which can easily cause discomfort to the patient and is not conducive to the smooth progress of the operation.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0031] When performing cervical suturing, a set of vaginal retractors are needed to stretch the vagina to expose the position of the cervix that needs to be sutured. However, since the vaginal retractors are made of hard material, they cause great damage to the inner wall of the vagina.

[0032] Example 1: A flexible support type suture device for cervical laceration, please refer to Figure 1-Figure 6, including a suturing device 1, a mounting ring 2 is arranged on the left part of the suturing device 1, the mounting ring 2 is elliptical, and the inner side of the mounting ring 2 is sealingly and slidably connected with six support members 3 distributed in an annular manner, the support member 3 is composed of a sealing rod and a support plate, the sealing rod is sealingly and slidably connected with the mounting ring 2, and the length of the sealing rods of the upper and lower support members 3 is greater than the length of the other four sealing rods, which is used to adapt to the patient's vaginal condition, a spring is fixedly connected between the side of the sealing rod of the support member 3 away from the central axis of the mounting ring 2 and the mounting ring 2, the side of the support member 3 away from the central axis of the mounting ring 2 cooperates with the mounting ring 2 to form an air storage cavity 301, the side of the support plate of the support member 3 away from the central axis of the mounting ring 2 is fixedly connected with an air bag 4, and a connecting hole 30 is arranged in the sealing rod of the support member 3 2. The connecting hole 302 is connected to the right side of the adjacent airbag 4, and the connecting hole 302 is connected to the adjacent air storage chamber 301, which is used to guide the gas in the air storage chamber 301 to the adjacent airbag 4. The sealing rod of the support member 3 cooperates with the mounting ring 2 to form a power chamber 303. The mounting ring 2 is provided with six annularly distributed air holes 304. The two adjacent power chambers 303 are connected through the adjacent air holes 304. The rear part of the mounting ring 2 is provided with seven-shaped through holes 501, which are connected to the adjacent air holes 304. The rear part of the right side of the mounting ring 2 is fixed with a gas delivery ball 5 (the gas delivery ball 5 is an existing device and will not be described in detail here) connected to the seven-shaped through holes 501, which is used to deliver external gas to the seven-shaped through holes 501.

[0033] Please refer to Figure 1 and Figure 7 An elastic member 6 is fixedly connected to the middle of the left side of the support plate on the six annularly distributed support members 3, and the middle part of the airbag 4 is fixedly connected to the elastic member 6, so that the elastic member 6 is stretched and deformed when the six support members 3 open the patient's vagina. The deformation of the elastic member 6 guides the deformation of the inner wall of the patient's vagina, reducing the friction between the inner wall of the patient's vagina and the device. A hole for the suture device 1 to pass through is set at the left end of the elastic member 6.

[0034] Please refer to Figure 1-Figure 4 and Figure 8 The front part of the mounting ring 2 is provided with an exhaust hole 701 connected with the adjacent vent hole 304, the rear part of the exhaust hole 701 is sealingly and slidingly connected with a fixed pressure plate 7, the middle part of the exhaust hole 701 is fixedly connected with a first fixed ring 8, the front part of the exhaust hole 701 is slidingly connected with a sliding member 9 in a front and rear limiting manner, and a spring is fixedly connected between the rear side of the sliding member 9 and the fixed pressure plate 7, the spring is used to detect the thrust of the gas in the power chamber 303 exerted on the fixed pressure plate 7, detect the air pressure in the power chamber 303, and then detect the reaction force of the inner wall of the patient's vagina on the support member 3, the position between the sliding member 9 and the fixed pressure plate 7 on the exhaust hole 701 is connected with the outside world, and the first fixed ring 8 is located on the front side of the place where the exhaust hole 701 is connected with the outside world.

[0035] Please refer to Figure 8A second fixing ring 10 is fixedly connected to the front side of the exhaust hole 701. The second fixing ring 10 is rotatably connected to a threaded member 11. The threaded member 11 is threadedly connected to the sliding member 9 to change the initial compression degree of the adjacent spring of the sliding member 9.

[0036] Please refer to Figure 3 , Figure 6 and Fig. 9 The rear part of the mounting ring 2 is sealed front and back and is connected with a dynamic ring 12 in a limited sliding manner. The front side of the dynamic ring 12 cooperates with the mounting ring 2 to form a dynamic cavity 121 connected with the adjacent vent hole 304. A spring is fixedly connected between the rear side of the dynamic ring 12 and the mounting ring 2. A static ring 13 is fixedly connected to the rear part of the mounting ring 2. The static ring 13 is located directly behind the dynamic ring 12. The static ring 13 and the middle part of the dynamic ring 12 are sealed together and are connected with a pressure relief piece 14 in a limited sliding manner. A tension spring is fixedly connected between the rear side of the static ring 13 and the pressure relief piece 14, and the tension of the tension spring is greater than the thrust of the gas in the dynamic cavity 121 on the pressure relief piece 14. An L-shaped hole 141 connected with the dynamic cavity 121 is provided in the pressure relief piece 14. The L-shaped hole 141 cooperates with the static ring 13 to block, so that the dynamic cavity 121 cannot be connected to the outside world through the L-shaped hole 141 at the beginning. The mounting ring 2, the dynamic ring 12, the static ring 13 and the pressure relief piece 14 cooperate to form a static cavity 131. Four rubber pieces 15 distributed in an annular manner are fixed to the rear sides of the dynamic ring 12 and the static ring 13. The rubber pieces 15 on the dynamic ring 12 have the same orientation as the adjacent rubber pieces 15 on the static ring 13. The rubber pieces 15 and the pressure relief piece 14 are frictionally matched to enable the pressure relief piece 14 to move back and forth between the dynamic ring 12 while the pressure relief piece 14 only moves backward in one direction. When the pressure relief piece 14 moves backward relative to the rubber piece 15, the rubber piece 15 deforms and reduces the friction between the two. When the pressure relief piece 14 moves forward relative to the rubber piece 15, the rubber piece 15 deforms and increases the friction between the two. The sum of the friction forces of the eight rubber pieces 15 on the pressure relief piece 14 is greater than the tension of the adjacent tension springs of the static ring 13.

[0037] Please refer to Figure 6 and Fig. 9 The static cavity 131 is connected to the seven-shaped through hole 501, and a blocking column 16 is sealed and slidably connected up and down in the seven-shaped through hole 501. A spring is fixed between the upper side of the blocking column 16 and the mounting ring 2, and the blocking column 16 and the seven-shaped through hole 501 are sealed and matched.

[0038] When performing cervical suturing, the doctor disinfects and lubricates the elastic member 6, and then inserts the elastic member 6 into the patient's vagina. The doctor then presses the gas delivery balloon 5, which delivers external gas to the seven-shaped through hole 501. The air pressure in the lower part of the seven-shaped through hole 501 increases and pushes the blocking column 16 upward, compressing the spring adjacent to the blocking column 16, so that the blocking column 16 releases the blockage of the seven-shaped through hole 501. Then, part of the gas in the seven-shaped through hole 501 enters the six power chambers 303, increasing the pressure in the power chamber 303. The adjacent support member 3 is pushed to the side away from the central axis of the mounting ring 2, and the adjacent spring of the support member 3 is compressed, and at the same time, the gas in the adjacent air storage chamber 301 is squeezed into the adjacent airbag 4 through the adjacent connecting hole 302, so that the airbag 4 expands, and the patient's vagina is stretched open by the flexible airbag 4 to protect the patient. Another part of the gas in the seven-shaped through hole 501 enters the static cavity 131, and at the same time, the dynamic cavity 121 is connected with the adjacent ventilation hole 304, so that the air pressure in the dynamic cavity 121, the static cavity 131 and the power cavity 303 are the same.

[0039] As the air pressure in the power chamber 303 gradually increases, the distance between the annularly distributed support members 3 gradually increases. When the distance between the annularly distributed support members 3 increases, due to the expansion of the patient's vaginal inner wall, there is a relative displacement between the patient's vaginal inner wall and the support member 3. If the support member 3 moves quickly, the patient's vaginal inner wall will not have time to move to the sides of the support member 3 relative to the support member 3, which will cause pulling on the patient's vaginal inner wall, easily damaging the patient's vaginal inner wall. The solution is as follows: As the support member 3 moves, the six support members 3 jointly stretch the elastic member 6, so that the elastic member 6 is stretched and deformed. As the elastic member 6 is stretched, the elastic member 6 stretches outward from the middle of the support member 3, while guiding the patient's vaginal inner wall to move to the sides of the support member 3. At the same time, combined with the lubrication of the elastic member 6, the probability of the patient's vaginal inner wall being damaged when it is stretched is reduced.

[0040] As the air pressure in the power chamber 303 gradually increases, a part of the gas in the power chamber 303 enters the exhaust hole 701, and the gas in the exhaust hole 701 pushes the fixed pressure plate 7 forward and compresses the spring adjacent to the fixed pressure plate 7. The fixed pressure plate 7 gradually passes the position where the exhaust hole 701 is connected to the outside world, and discharges the gas in the power chamber 303 to the outside world through the exhaust hole 701. At this time, the doctor knows that the air pressure in the power chamber 303 has reached the specified pressure (the specified pressure refers to the maximum pressure set by the doctor to prevent the patient's vagina from being damaged). The doctor stops pressing the gas delivery ball 5 and rotates the threaded member 11. The threaded member 11 drives the sliding member 9 to move backward through the thread, compresses the spring adjacent to the fixed pressure plate 7, and pushes the fixed pressure plate 7 to the initial position through the spring. Then, it is observed whether the position of the cervix to be sutured is fully exposed. If not, the doctor slowly presses the gas delivery ball 5 to deliver external gas to the power chamber 303 and push the support member 3 to move slowly until the position of the cervix to be operated on is fully exposed. At this time, the doctor stops pressing the gas delivery ball 5 and starts to use the suture device 1 to suture the patient's cervical laceration.

[0041] When the doctor stops pressing the gas delivery ball 5, the blocking column 16 moves downward under the action of its adjacent spring and blocks the seven-shaped through hole 501 again, that is, the static cavity 131 is separated from the adjacent vent hole 304. During the operation, the patient may experience uterine contractions due to stimulation. At this time, the doctor communicates with the patient and calms the patient's emotions. At the same time, due to uterine contractions, the pelvic floor muscle groups work together to make it difficult for the patient's vaginal wall to be in a relaxed state. As the patient's vaginal wall exerts force and contracts, the six support members 3 are squeezed together in the direction close to the central axis of the mounting ring 2, so that the air pressure in the power cavity 303 and the dynamic cavity 121 increases. At this time, a pressure difference is generated between the dynamic cavity 121 and the static cavity 131, and the dynamic ring 12 moves backward, compressing The spring adjacent to the dynamic ring 12 and the dynamic ring 12 jointly push the pressure relief part 14 backward through the four adjacent rubber parts 15. The pressure relief part 14 moves relative to the four adjacent rubber parts 15 on the static ring 13 and stretches the tension spring adjacent to the static ring 13. Then, a contraction ends and the inner wall of the patient's vagina relaxes. At this time, the support part 3 moves again in the direction away from the central axis of the mounting ring 2 under the action of the air pressure in the adjacent power chamber 303. At this time, the air pressure in the power chamber 303 and the dynamic chamber 121 is equal to the air pressure in the static chamber 131. The dynamic ring 12 moves forward and resets under the action of its adjacent spring. When the dynamic ring 12 moves forward, the pressure relief part 14 is subjected to the friction force of the four adjacent rubber parts 15 of the static ring 13, so that the pressure relief part 14 does not move forward with the dynamic ring 12.

[0042] If the patient's contractions end quickly, the doctor will then push the pressure relief piece 14 forward to overcome the friction of the eight rubber pieces 15 on the pressure relief piece 14 and reset it. If the patient continues to have contractions, it is necessary to reduce the stimulation to the patient. The specific operation is as follows: As the patient continues to have contractions, the inner wall of the patient's vagina continues to relax, so that the pressure relief piece 14 continues to move backward until the rear end of the L-shaped hole 141 moves to the outside of the static ring 13, so that the static ring 13 releases the blockage of the L-shaped hole 141. At this time, the gas in the dynamic chamber 121 and the power chamber 303 is discharged to the outside through the L-shaped hole 141, so that the support piece 3 moves toward the direction close to the central axis of the mounting ring 2, reducing the supporting force on the inner wall of the patient's vagina, thereby reducing the stimulation to the patient. After the patient's contractions end, the doctor pushes the pressure relief piece 14 forward and resets it, so that the static ring 13 re-blocks the L-shaped hole 141, and at the same time, the adjacent tension spring of the static ring 13 is reset. Then the doctor repeats the above-mentioned steps of pressing the gas infusion ball 5, reuses the support piece 3 to open the inner wall of the patient's vagina, and continues the suture operation.

[0043] After the suturing operation is completed, the doctor takes out the suturing device 1 and then rotates the threaded member 11. The threaded member 11 drives the sliding member 9 forward through the thread until the sliding member 9 moves forward to the limit position (at this time, the length of the spring between the sliding member 9 and the fixed pressure plate 7 is less than the distance between the sliding member 9 and the exhaust hole 701 and the outside world). During the movement of the sliding member 9, the fixed pressure plate 7 is pushed by the air pressure in the power chamber 303 to follow the sliding member 9 forward until the fixed pressure plate 7 passes the exhaust hole 701 and is connected to the outside world. The gas in the power chamber 303 is discharged to the outside world through the exhaust hole 701. Then, the support member 3 moves and resets in the direction close to the central axis of the mounting ring 2 under the action of its adjacent spring. At this time, the doctor takes the support member 3 out of the patient's body and rotates the threaded member 11 again. The threaded member 11 drives the sliding member 9 to move backward and reset through the thread, and the sliding member 9 drives the fixed pressure plate 7 to move forward and reset through the spring.

[0044] When a doctor uses a stapler to perform cervical suture, the suture end of the stapler needs to be inserted into the patient's body, so that the doctor's hand is far away from the suture end of the stapler. The doctor needs to overcome the stapler's own gravity and perform delicate sutures, which makes the operation difficult and makes the doctor more likely to feel tired.

[0045] Example 2: Based on Example 1, please refer to Figure 3 , Figure 4 , Fig.10 and Fig.11 It also includes two connecting rods 17 symmetrically distributed in the upper and lower parts, the left end of the connecting rod 17 is hinged to the left part of the support plate of the adjacent support member 3, and the right ends of the two symmetrically distributed connecting rods 17 are hinged to a limit ring 18, and the middle part of the limit ring 18 is ball-connected with an arc ring 19, which is in contact with the suture device 1.

[0046] Please refer to Fig.10 and Fig.11 The limiting ring 18 is slidably connected to the limiting member 20 in a left-right limiting manner. The right end of the connecting rod 17 and the limiting member 20 are driven by a gear rack. The limiting member 20 cooperates with the suture device 1 to limit the maximum angle at which the suture device 1 can rotate.

[0047] When performing cervical suturing, repeat the steps of Example 1, use the support member 3 to stretch the elastic member 6 to expose the patient's cervical suture site. As the distance between the upper and lower support members 3 gradually increases, the support member 3 drives the limit ring 18 to move left through the adjacent connecting rod 17. At the same time, the connecting rod 17 drives the limit member 20 to move left relative to the limit ring 18 through the gear and the rack, thereby reducing the distance between the right side of the limit member 20 and the limit ring 18. Then the doctor passes the suturing end of the stapler 1 through the arc ring 19, and uses the arc ring 19 to provide support for the stapler 1 to suture the cervical laceration site.

[0048] As the operation progresses, the doctor's fatigue gradually increases. In order to prevent the doctor from making operational errors, that is, to prevent the doctor from controlling the swing amplitude of the stapler 1 to be large and causing harm to the patient, the specific operation is as follows: Since the stapler 1 swings with the center of the arc ring 19 as the midpoint, if the stapler 1 swings with a large amplitude, the stapler 1 contacts the limiter 20, and the limiter 20 limits the stapler 1 from continuing to swing. As the distance between the six support members 3 increases, the distance between the limiter 20 and the limiter ring 18 gradually decreases until the patient's cervical suture position is completely exposed. By reducing the distance between the limiter 20 and the limiter ring 18, the swingable angle of the stapler 1 is increased, which is convenient for the doctor to operate. At the same time, the limiter 20 is used to limit the maximum swing angle of the stapler 1 to protect the patient.

[0049] After the suturing is completed, the doctor pulls out the stapler 1 to the right, causing the stapler 1 to lose contact with the arc ring 19, and then repeats the steps in Example 1 to gradually reduce the distance between the six support members 3 and reset them. As the distance between the upper and lower support members 3 decreases, the upper and lower support members 3 jointly drive the limit ring 18 to move right and reset through the adjacent connecting rod 17. At the same time, the connecting rod 17 drives the limit member 20 to move right and reset relative to the limit ring 18 through the gear and rack transmission.

[0050] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present application, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of this application.
