Description

Technical Field

[0001] This invention relates to a cervical hemostasis device, and more specifically, to a cervical ligation hemostasis device. Background Technology

[0002] Postpartum hemorrhage is a common complication in postpartum women, affecting approximately 3% to 5% of all mothers. In my country, postpartum hemorrhage is the leading cause of maternal mortality. There are many causes of postpartum hemorrhage, with uterine atony being the most common.

[0003] Existing hemostasis methods include: 1. using hemostatic forceps to clamp the cervix locally; 2. using balloon compression.

[0004] Currently, there are three types of hemostatic forceps. The first type is straight hemostatic forceps and toothless hemostatic forceps, which are used for superficial hemostasis and tissue separation at the surgical site. Toothed hemostatic forceps are mainly used for hemostasis of strong tissues and for lifting the incision site. The second type is curved hemostatic forceps, which are used for hemostasis of deep tissues or internal organs. Toothed hemostatic forceps are not suitable for clamping blood vessels, nerves, or other tissues. The third type is mosquito hemostatic forceps, which are smaller and suitable for separating small blood vessels and connective tissue around nerves. They are used for hemostasis of small blood vessels but are not suitable for clamping large or hard tissues. Therefore, when using hemostatic forceps, it is necessary to consider many factors and choose the appropriate forceps. Furthermore, medical staff need to hold the forceps with their hands at all times, which leads to low work efficiency.

[0005] Most existing hemostatic balloons rely entirely on pressure on the wound to achieve hemostasis. Therefore, the balloon needs to be inserted into the wound and then inflated or filled with water so that the balloon can compress the wound to achieve hemostasis. However, not only is it necessary to control the pressure of the balloon, but it is also impossible to effectively guide the blood that has already appeared to flow out quickly. Generally, it is even necessary to perform blood removal operations before and after hemostasis, which brings certain risks and pain to the mother.

[0006] Based on this, the workload of medical staff can be reduced and the efficiency of surgery can be improved. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the present invention aims to provide a cervical ligation hemostasis device. This device can ligate the upper part of the cervix to block blood flow and achieve hemostasis without requiring medical staff to hold the cervix for extended periods, thus reducing the workload of medical staff, improving surgical efficiency, and reducing medical expenses.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a cervical ligation hemostasis device, comprising an inner tube and an operating tube, wherein the operating tube is slidably connected to the inner tube, a ligation band is installed on the inner tube, and a binding buckle is provided on the ligation band, the binding buckle being used to adjust the opening size of the ligation band; when the operating tube slides along the inner tube, one end of the operating tube pushes the binding buckle to cause the ligation band to contract.

[0009] The inner tube is provided with guide rods, and there are two guide rods located on both sides of the inner tube respectively;

[0010] The guide rod includes a mounting part and a hinge part. One end of the mounting part is rotatably connected to the inner tube, and one end of the hinge part is hinged to the end of the mounting part away from the inner tube.

[0011] The inner tube is provided with a rotating component for driving the installation part to rotate and a control component for controlling the hinge part to flip. The installation part includes a storage position along the axial direction of the inner tube and a working position along the radial direction of the inner tube. The rotating component is used to control the installation part to rotate from the storage position to the working position.

[0012] In summary, the present invention has the following beneficial effects: the ligation band is placed on the cervix, and then the operating tube is pushed so that the front end of the operating tube pushes the binding buckle, thereby causing one end of the ligation band to contract, gradually compressing upwards, blocking the blood vessels in the lower segment of the uterus, and achieving hemostasis.

[0013] The design of this inner tube also allows the ligation band to be extended further up the cervix for better hemostasis.

[0014] It allows for easy placement of the ligation band on the cervix, facilitating the ligation procedure. Additionally, it monitors the ligation process, ensuring stability while preventing over-binding and secondary injury to the wound. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] Reference Figures 1 to 6 As shown, to achieve the above objectives, the present invention provides the following technical solution: a cervical ligation hemostasis device, comprising an inner tube 1 and an operating tube 2, the operating tube 2 being slidably connected to the inner tube 1, a ligation band 11 being installed on the inner tube 1, and a binding buckle 12 being provided on the ligation band 11, the binding buckle 12 being used to adjust the opening size of the ligation band 11; when the operating tube 2 slides along the inner tube 1, one end of the operating tube 2 pushes the binding buckle 12 to cause the ligation band 11 to contract.

[0024] The inner tube 1 is provided with guide rods 3. There are two guide rods 3, which are located on both sides of the inner tube 1 respectively. The distance between the two guide rods 3 is less than the length of the cervix.

[0025] The guide rod 3 includes a mounting part 31 and a hinge part 32. One end of the mounting part 31 is rotatably connected to the inner tube 1, and one end of the hinge part 32 is hinged to the end of the mounting part 31 away from the inner tube 1.

[0026] The inner tube 1 is provided with a rotating member 4 for driving the mounting part 31 to rotate and a control member 5 for controlling the hinge part 32 to flip. The mounting part 31 includes a storage position along the axial direction of the inner tube 1 and a working position along the radial direction of the inner tube 1. The rotating member 4 is used to control the mounting part 31 to rotate from the storage position to the working position.

[0027] The inner tube 1 includes an operating end and a working end. The operating end is the handheld end for medical staff, and the working end is the working end located near the cervix.

[0028] The ligation band 11 is placed on the cervix, and then the operating tube 2 is pushed so that the front end of the operating tube 2 pushes the binding buckle 12, thereby causing one end of the ligation band 11 to contract and gradually compress upwards, blocking the blood vessels in the lower segment of the uterus and achieving hemostasis.

[0029] The design of the inner tube 1 also allows the ligation band 11 to be extended to a higher position on the cervix, achieving a better hemostatic effect.

[0030] The present invention is divided into two types according to the positional relationship between the guide rod 3 and the ligation band 11: 1. When the guide rod 3 is located behind or on the same side as the ligation band 11, it has the following function: when the guide rod 3 is in contact with the cervix, the operating end of the inner tube 1 can be used to determine whether there is contact. Then, when the ligation band 11 is pushed to bind through the operating tube 2, the binding situation can be checked through the operating end of the inner tube 1, and then subsequent operations can be performed.

[0031] 2. When the guide rod 3 is located in front of the ligation band 11, it has both function one and function two. The guide rod 3 causes the cervix to contract initially, which makes it easier for the ligation band 11 to be placed on the cervix.

[0032] Based on the functions of Function 1 and Function 2, the ligation band 11 can be easily placed on the cervix to facilitate the ligation operation. In addition, it can monitor the ligation action, ensuring the stability of the ligation binding while avoiding over-binding and causing secondary injury to the wound.

[0033] The aforementioned follow-up procedures include cutting the ligation band 11 to retract the inner tube 1 and temporarily binding the ligation band 11 to the cervix. After complete hemostasis, the ligation band 11 is cut to complete the recovery.

[0034] The procedures for the ligation band 11 before the inner tube 1 is retracted include: 1. cutting it directly below the binding buckle 12; 2. placing the entire ligation band 11 on the cervix and separating it from the inner tube 1.

[0035] As a further feature, the ligature 11 is equipped with one-way teeth, which allows the restraint buckle 12 to move only in one direction.

[0036] Example 1: Based on the function of function one, it has the following structure:

[0037] The control component 5 includes a torsion spring 51 disposed between the mounting part 31 and the hinge part 32, and a drive rope 52 connected to the hinge part 32, with one end of the drive rope 52 extending outward from the operating end of the inner tube 1.

[0038] The design of the control component 5 enables effective expansion and retraction control of the hinge 32, effectively controlling the size of the equipment when it is ready to work, and facilitating initial placement.

[0039] When the device is about to be inserted, the hinge 32 is flipped to be close to the mounting part 31 by pulling the drive rope 52. When the drive rope 52 is released, the hinge 32 is flipped to the unfolded position by the action of the torsion spring 51.

[0040] A further design incorporates a pull ring at the operating end of the inner tube 1, which is connected to the drive ropes 52 on both sides to achieve interlocking control.

[0041] The two hinged portions 32 are arranged in an unfolded manner, moving away from the mounting portion 31. The hinged portions 32 gradually extend from bottom to top away from the outer tube, thereby gradually forming an initial restraint on the cervix during the process of approaching it, achieving a preset width. The preset width is the inner tube diameter plus the lateral length of the two mounting portions 31 plus part of the width of the inclined surface of the hinged portions 32.

[0042] A first sensor 6 is provided on the side of the hinge 32 facing the inner tube 1, and a second sensor 7 is provided on the operating end of the inner tube 1. The first sensor 6 and the second sensor 7 are linked together.

[0043] When the ligation band 11 binds the cervix, the second sensor 7 is triggered.

[0044] The first sensing element 6 includes a protrusion 61 and a drive spring 62. The drive spring 62 is used to drive the protrusion 61 to protrude toward the inner tube 1. When the hinge part 32 contacts the cervix, the cervix pushes the protrusion 61 to retract and compresses the drive spring 62.

[0045] When the ligation band 11 binds the cervix, the cervix separates from the protrusion 61, and the drive spring 62 drives the protrusion 61 to extend.

[0046] The operating end of the inner tube 1 is provided with a visual cavity for the installation of the second sensor 7. The second sensor 7 includes a first magnetic block 71 and a second magnetic block 72. The first magnetic block 71 is connected to the protrusion 61 through a connecting rope 73. The second magnetic block 72 is fixedly connected to the inner tube 1. When the cervix pushes the protrusion 61 to retract, the first magnetic block 71 and the second magnetic block 72 are magnetically connected.

[0047] When the drive spring 62 drives the protrusion 61 to extend, the first magnetic block 71 and the second magnetic block 72 separate.

[0048] The elastic force of the drive spring 62 is greater than the magnetic force between the first magnetic block 71 and the second magnetic block 72. In addition to the first magnetic block 71 and the second magnetic block 72, the two can also be connected by a tension spring. Similarly, the elastic force of the tension spring is less than the elastic force of the drive spring 62.

[0049] The first sensor 6 and the second sensor 7 are connected by a connecting rope 73. When the hinge part 32 has not yet come into contact with the cervix, the drive spring 62 drives the protrusion 61 to extend. At this time, the connecting rope 73 is pulled by the protrusion 61, and the first magnetic block 71 and the second magnetic block 72 separate.

[0050] When the hinge 32 comes into contact with the cervix, the cervix pushes the protrusion 61 to slide inward and compresses the drive spring 62. At this time, the connecting rope 73 retracts, and the first magnetic block 71 and the second magnetic block 72 are attracted together.

[0051] When the ligation band 11 has finished binding the cervix, the cervix separates from the protrusion 61. At this time, the protrusion 61 extends under the action of the compression spring and drives the first magnetic block 71 to move through the connecting rope 73, thereby separating the first magnetic block 71 and the second magnetic block 72.

[0052] Medical staff can hold the operating end and observe the attraction status of the first magnetic block 71 and the second magnetic block 72 through the visual cavity, thereby judging the working status of the working end and improving their understanding of the working status. In addition, the magnetic design is more convenient for medical staff to observe than the tension spring design, avoiding misjudgment.

[0053] Example 2: Based on function 2, it has the following structure;

[0054] The inner tube 1 includes a middle cylinder 8, and the guide rod 3 and the rotating part 4 are all mounted on the middle cylinder 8. The middle cylinder 8 is slidably connected to the inner tube 1.

[0055] The design of the middle tube 8 allows for adjustment of the distance between the guide rod 3 and the ligation band 11 by sliding the inner tube. First, the cervix is ​​initially bound by the guide rod 3, and then the ligation band 11 is placed on the cervix by pushing the inner tube 1.

[0056] The middle cylinder section 8 includes a middle cylinder ring and middle cylinder rods located on both sides of the middle cylinder ring. To prevent the middle cylinder section 8 from rotating, a middle cylinder slider is provided on the middle cylinder ring, and a straight slide is provided on the inner tube 1.

[0057] The rotating component 4 includes a driving wheel 41, a driven wheel 42, and a transmission part 43. The driving wheel 41 and the driven wheel 42 are linked together through the transmission part 43. The driven wheel 42 is connected to the mounting part 31. An extension groove 13 is provided on the operating end of the inner tube 1, and one side of the driving wheel 41 extends out from the extension groove 13.

[0058] The design of the rotating component 4 allows for adjustment of the initial position of the guide rod 3, facilitating the insertion of the device through the vaginal opening to the cervix.

[0059] The transmission unit 43 can be a rack or a belt. By connecting the driving wheel 41 and the driven wheel 42, when the operator manually moves the driving wheel 41, the driven wheel 42 can rotate accordingly, thereby driving the guide rod 3 installed on the driven wheel 42 to rotate.

[0060] To prevent the guide rod 3 from rotating excessively, a limited rotation structure can be set at the position of the driving wheel 41 or the driven wheel 42, or at the position of the guide rod 3, to limit its rotation range. The specific limited rotation structure can adopt existing technology, which will not be elaborated here.

[0061] When preparing to insert it into the vaginal opening, the drive wheel 41 moves the guide rod 3 to the storage position. When it is about to reach the position, the drive wheel 41 moves the guide rod 3 to the working position, or it can stay between the working position and the storage position according to its specific needs.

[0062] The working end of the inner tube 1 is provided with an assembly groove 14 and a sealing ring 15. The assembly groove 14 includes a first opening 16 for the installation of the ligature 11 and a second opening 17 for the ligature 11 to extend out. The sealing ring 15 is used to seal the first opening 16.

[0063] An installation rod 18 is provided in the assembly slot 14, and one end of the tying strap 11 is sleeved on the installation rod 18;

[0064] The inner tube 1 is provided with an operating ring 19 at its operating end. The operating ring 19 is connected to the sealing ring 15 via a connecting rod. The sealing ring 15 is provided with a third opening 151 corresponding to the first opening 16.

[0065] The design of this structure enables the entire ligation band 11 to be detached from the inner tube 1. The specific operation is as follows: the ligation band 11 is divided into a binding opening for being fitted onto the cervix and a fixing opening for being fitted onto the mounting rod 18 by the binding buckle 12. When the sealing ring 15 blocks the first opening 16, the binding opening extends out from the second opening 17. When the operating tube 2 is pushed, since one end of the ligation band 11 abuts against the mounting rod 18, the binding buckle 12 binds the cervix along the ligation band 11.

[0066] When the binding is completed, the operating ring 19 is rotated so that the third opening 151 on the sealing ring 15 corresponds to the first opening 16. At this time, the operating tube 2 is pushed again to move the fixing port out from the third opening 151 along the mounting rod 18. While completing the binding operation, the ligature 11 is separated from the inner tube 1, which facilitates the recycling operation of the inner tube 1.

[0067] This procedure can be selected based on the specific length of the ligature 11, the degree of binding, and the amount of bleeding.

[0068] One end of the operating tube 2 is provided with a pushing part 21. The pushing part 21 is provided with a pushing groove 22 for the binding buckle 12 to be embedded. The position of the pushing groove 22 is correspondingly arranged with the position of the assembly groove 14;

[0069] A cutting structure 23 is arranged in the pushing groove 22.

[0070] The cutting structure 23 includes a pushing cavity 24, cutting parts 25 located on both sides of the pushing groove 22, and a control part 26 located in the pushing groove 22. The cutting parts 25 and the control part 26 both slide in the pushing cavity 24. A reset spring 27 for controlling the reset of the cutting parts 25 and the control part 26 is arranged in the pushing cavity 24;

[0071] The pushing cavity 24 is arranged in a "U" - shaped structure. The cutting parts 25 are arranged on both sides of the pushing cavity 24, and the control part 26 is arranged in the middle of the pushing cavity 24. The linkage part between the control part 26 and the cutting parts 25 is arranged in an inclined plane. When the control part 26 is pushed inward, the two cutting parts 25 move inward simultaneously through the inclined plane.

[0072] Limit blocks 28 are arranged on both sides of the pushing groove 22 along the radial direction of the operating tube 2.

[0073] As Figure 5 shown, in the design of this cutting structure 23, when the binding buckle 12 is pushed through the pushing groove 22, the binding buckle 12抵触 the control part 26, causing the control part 26 to be touched and thus compressing the reset spring 27, and the two cutting parts 25 on both sides contract simultaneously through the inclined plane, avoiding the cutting teeth on the cutting parts 25 from affecting the binding buckle 12.

[0074] When the binding is completed, at this time the binding buckle 12 will move upward, thus disengaging from the pushing groove 22. At this time, the ligation band 11 at the lower end of the binding buckle 12 is located in the pushing groove 22. When the binding buckle 12 is separated from the control part 26, the cutting parts 25 extend under the action of the reset spring 27. At this time, the operating tube 2 is rotated, so that the cutting parts 25 cut the ligation band 11, making the binding opening separate from the inner tube 1, and completing the recycling operation of the inner tube 1.

[0075] Furthermore, it further includes a rotation - limiting structure. The rotation - limiting structure is used to limit the rotation of the operating tube, and the rotation - limiting structure is linked with the second sensing part.

[0076] The rotation - limiting structure includes a circuit board. The circuit board includes two input signals and one output signal. The two input signals are respectively connected to two groups of second sensing parts. When the first magnetic attraction block and the second magnetic attraction block are connected, the circuit is connected, thereby triggering the input signals. When both input signals are triggered, the circuit board emits an output signal.

[0077] The rotation limiting structure also includes a micro motor and a rotation limiting plate. The micro motor is used to control the lead screw assembly. The lead screw assembly is connected to the rotation limiting plate. When a limit block is set on the operating tube and a rotation range is set at the working end of the inner tube, the rotation of the limit block will be limited when the limiting plate is located within the rotation range.

[0078] At this point, the operating tube can only slide along the direction of the inner tube.

[0079] When both sets of second sensors are triggered, the micro motor controls the rotation limit plate to move back. At this time, the limit block can rotate circumferentially along the rotation range, thereby realizing the cutting operation.

[0080] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
