Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a hysteroscopic uterine fibroid grasping forceps that helps medical staff to grasp fibroids in the limited operating space of hysteroscopy, thereby reducing surgical risks and improving surgical efficiency. Background Technology

[0002] Uterine fibroids are the most common benign tumors in gynecological diseases. Some patients require myomectomy. Uterine fibroids are classified according to their location as subserosal fibroids, intramural fibroids, and submucosal fibroids. Submucosal fibroids require hysteroscopic removal. However, due to their hard texture, effective instruments are usually needed to clamp the fibroid during removal. Effective clamping allows for faster removal. Furthermore, to prevent excessive use of distending fluid during hysteroscopic myomectomy, it is generally recommended to electrocautery both sides of the fibroid and then use an ovum forceps to clamp and remove the remaining fibroid. However, current methods are all blind procedures, relying solely on the surgeon's touch, which can easily lead to perforation, endometrial damage, or ineffective clamping, wasting surgical time and increasing the patient's surgical risk. Currently available uterine fibroid grasping forceps are designed for laparoscopic myomectomy. The large-diameter forceps are too thick to be operated with a hysteroscope, and it is also difficult to enter the cervix. Moreover, the limited operating space makes it difficult to adjust the position of the forceps head for clamping, making it unsuitable for hysteroscopic myomectomy. Currently, a Chinese utility model patent entitled "A Large Grasping Forceps for Uterine Myomas" (patent number ZL201520009173.X, publication date 2015-07-08) includes a forceps bar with a pull rod inside. The front end of the forceps bar is connected to a fixed forceps head, and the rear end is connected to a fixed handle. A movable handle is hinged to the fixed handle. The fixed forceps head is hinged to the movable forceps head via a first hinge axis, and the movable forceps head is hinged to the front end of the pull rod via a second hinge axis. The rear end of the pull rod abuts against the movable handle, and when the movable handle moves towards the fixed handle, the pull rod moves backward and closes the movable forceps head towards the fixed forceps head. The advantages are: during use, the tissue to be grasped is placed on the fixed clamp head, facilitating the first step of fixing the grasped tissue. Then, the movable handle is pressed by hand, at which point the movable clamp head closes towards the fixed clamp head, clamping the tissue. After closing, the grasped tissue is located within the clamp cavity, which is conducive to the next step of traction, thus facilitating the grasping and traction of tissue during uterine fibroid surgery. However, although this patent can also complete fibroid removal surgery to a certain extent, the limited operating space may prevent proper adjustment of the clamp head position for clamping, making it unsuitable for hysteroscopic fibroid removal surgery.

[0003] How to solve the above problems has become an urgent technical issue. Utility Model Content

[0004] The purpose of this invention is to provide a hysteroscopic uterine fibroid grasping forceps that allows medical staff to grasp fibroids within the limited operating space of a hysteroscope, thereby reducing surgical risks and improving surgical efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a hysteroscopic uterine fibroid grasping forceps, including a forceps head, a forceps body, and a forceps handle.

A sealing ring is provided inside the forceps body near the forceps head. A row of teeth is evenly distributed along the length direction of the forceps head inside the forceps head.

[0007] Furthermore, the rotating assembly includes a transmission rod, on which a transmission shaft is sleeved. One end of the transmission shaft is threadedly connected to the pliers body, and the other end of the transmission shaft is movably connected to the pliers handle via a bearing. A connecting rod is provided at the front end of the transmission rod and is movably connected to the pliers head. A connecting ball is provided at the end of the transmission rod, and a connecting groove is provided on the operating handle that can be movably connected to the connecting ball.

[0008] Furthermore, a tightening nut that can contact and engage with the outer wall of the drive shaft is provided on the pliers handle, and a buffer ring that can contact the drive shaft is provided inside the pliers handle.

[0009] Furthermore, an adjustment part is integrally provided on the outer side of the pliers body near the pliers handle.

[0010] Furthermore, a fixing plate with locking teeth is provided at the lower end of the operating handle, and a positioning tooth is provided at the bottom of the pliers handle to cooperate with and fix together with the fixing plate.

[0011] Furthermore, a spring is provided between the clamp handle and the operating handle.

[0012] Furthermore, the teeth are arranged in a gradient structure inside the pliers head, wherein the height of the teeth near the inner side of the pliers head is lower than the height of the teeth near the outer side, and each tooth has at least three teeth.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 This utility model provides a hysteroscopic myomectomy forceps, comprising a forceps head 1, a forceps body 2, and a forceps handle 3. An operating handle 4 is hinged to the forceps handle 3. A rotating assembly 5 is movably mounted inside the forceps body 2. The front end of the rotating assembly 5 extends through the interior of the forceps body 2 and is movably connected to the forceps head 1. The rear end of the rotating assembly 5 extends through the interior of the forceps handle 3 and is movably connected to the operating handle 4. A sealing ring 21 is provided inside the forceps body 2 near the forceps head 1. A row of teeth 11 is evenly distributed along the length of the forceps head 1. The operation handle 4, in conjunction with the forceps handle 3, allows the rotating assembly 5 to control the opening and closing of the forceps head 1. The evenly distributed teeth inside the forceps head 1 facilitate more precise myomectomy. The design is robust and labor-saving. The sealing ring 21 prevents water leakage during use, avoiding affecting the distension effect and hindering the operation. The rotating component 5 allows the forceps body 2 and the forceps head 1 to rotate in a certain direction, thereby adjusting the angle of the forceps head 1. This facilitates accurate clamping of fibroids by medical staff in the limited operating space of the hysteroscope, reducing operation time and the use of distension fluid, thus reducing the risk of water intoxication in patients and improving the safety and efficiency of the operation. The length of the forceps body 2 is 35cm and the diameter of the front end of the forceps body 2 is 3mm, which is suitable for use with hysteroscopes with operating ports. Appropriate indentations and anti-slip textures can be set on the operating handle 4 as needed, making it easy for medical staff to grip and preventing slippage.

[0024] In this invention, the rotating assembly 5 includes a transmission rod 51, on which a transmission shaft 52 is sleeved. One end of the transmission shaft 52 is threadedly connected to the pliers body 2, and the other end is movably connected to the pliers handle 3 via a bearing 53. A connecting rod 54 is provided at the front end of the transmission rod 51 and is movably connected to the pliers head 1. A connecting ball 55 is provided at the end of the transmission rod 51. A connecting groove 41 is provided on the operating handle 4 to movably connect with the connecting ball 55. The pliers handle 3 is movably connected to the transmission shaft 52 via the bearing 53, thereby movably connecting the pliers body 2 and the pliers handle 3, facilitating the rotation of the pliers body 2 and the pliers handle 3. Pulling the operating handle 4 causes the connecting groove 41 to move the connecting ball 55, thereby causing the connecting ball 55 to move together with the transmission rod 51 and the connecting rod 54 at its front end, thus realizing the control of opening and closing of the pliers head 1.

[0025] In this utility model, a tightening nut 31 is provided on the pliers handle 3, which can contact and cooperate with the outer wall of the drive shaft 52, and a buffer ring 33 is provided inside the pliers handle 3, which can contact the drive shaft 52; the tightening nut 31 can adjust the tightness between the pliers handle 3 and the drive shaft 52, and the buffer ring 33 can support and position the drive shaft 52 left and right, making it convenient to rotate.

[0026] In this invention, an adjustment part 22 is integrally provided on the outer side of the pliers body 2 near the pliers handle 3; the pliers body 2 can be easily rotated through the adjustment part 22.

[0027] In this invention, a fixing plate 42 with locking teeth is provided at the lower end of the operating handle 4, and a positioning tooth 32 is provided at the bottom of the clamp handle 3, which can cooperate with the fixing plate 42 to fix together; the fixing plate 42 and the positioning tooth 32 can cooperate to complete the automatic fixation of the operating handle 4, saving the surgeon's time to exert force.

[0028] In this invention, a spring piece 6 is provided between the forceps handle 3 and the operating handle 4; the elasticity of the spring piece 6 can help medical staff to squeeze and release the forceps handle 3 and the operating handle 4.

[0029] In this invention, the teeth 11 are arranged in a gradient structure inside the pliers head 1. The teeth 11 near the inner side of the pliers head 1 are lower in height than the teeth 11 near the outer side. Each tooth 11 has at least three teeth. The design of multiple rows of high and low teeth makes the pliers head 1 grip the fibroid more firmly and also facilitates the twisting and pulling of the fibroid.

[0030] In practical use, the tightness of the operating nut 31 is adjusted to ensure the patient is in the lithotomy position. The hysteroscope with the operating port is inserted into the uterine cavity, and the capsule of the fibroid is first electrocauterized. After opening the capsule, the forceps 2 is inserted through the operating port. The medical staff holds the forceps handle 3 and the operating handle 4, placing four fingers on the operating handle 4. After the forceps 2 enters the uterine cavity, the location of the fibroid is directly visualized and determined. The clamping angle of the forceps 2 and the front forceps head 1 is adjusted using the operating adjustment part 22. After determining the position, the medical staff pinches the operating handle 4 to close the forceps head 1. The teeth 11 inside the forceps head 1 bite the fibroid tissue. During the pinching process, the operating handle 4 is automatically fixed through the cooperation of the fixing plate 42 and the positioning teeth 32. Finally, the fibroid is rotated, removed, and dragged out of the uterine cavity to complete the operation. This method is beneficial for single-person operation, allowing medical staff to accurately clamp the fibroid within the limited operating space of the hysteroscope, reducing operation time, lowering the risk of water intoxication in patients, and improving surgical safety and efficiency.
