Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable uterine lift device. Background Technology
[0002] In laparoscopic uterine or ovarian surgeries, the position of the uterus can significantly affect the surgeon's operation. In some patients, lax uterine ligaments and a high degree of uterine mobility impair surgical efficiency and increase surgical risks. In other patients, a retroverted uterus, far from the abdominal wall and obscured by the intestines, obstructs the surgical field and increases the risk of intestinal injury. In these cases, a uterine manipulator is particularly needed to help bring the uterus closer to the abdominal wall, facilitating surgical manipulation and improving surgical quality and efficiency.
[0003] For example, the uterine manipulator disclosed in publication number CN203609482U includes a guide rod, a hollow cannula, a cervical fixator, and a uterine head. The uterine head is fixed to the front end of the cervical fixator, which is fitted onto the hollow cannula. The guide rod is installed inside the hollow cannula, and the rear end of the hollow cannula has a threaded cone with at least two openings along the length of the hollow cannula. The uterine manipulator also includes a limiting tube for positioning the hollow cannula and the guide rod. The inner diameter of the limiting tube is larger than the outer diameter of the guide rod, and the inner wall of the front end of the limiting tube has an internal thread that matches the thread of the threaded cone. This structure is relatively simple and cannot be adjusted in angle or rotated to achieve the best surgical effect, making it difficult for doctors to lift the uterus. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable-angle uterine lifter. This invention allows for appropriate angle adjustment, facilitating the doctor's lifting of the uterus. After adjustment, the angle is automatically locked, and the lifter can rotate 360° and move forward and backward.
[0005] The technical solution of this utility model is as follows: An adjustable angle uterine lifter includes a ball-head pull rod, a connecting piece connected to the front end of the ball-head pull rod, the other end of the connecting piece being movably connected to the end of a control head, a clamp seat connected to the end of the control head, a clamp rod head connected to the clamp rod head, a clamp rod head being fixedly connected to one end of the clamp rod, the clamp rod being sleeved on the outside of the ball-head pull rod, a sliding sleeve provided on the outside of the clamp rod head, a clamp rod front connecting sleeve provided on the front side of the sliding sleeve, a locking seat provided on the inside of the clamp rod head, and the sliding sleeve being fixedly connected to the locking seat; a handle is connected to the rear end of the ball-head pull rod.
[0006] In the aforementioned adjustable-angle uterine lifter, the front side of the clamp seat is provided with a clamp for installing the operating head, and the rear side of the clamp seat is symmetrically provided with two convex shafts. One end of the locking seat is provided with two grooves that cooperate with the convex shafts, and the middle is provided with a locking hole. The sliding sleeve is fixedly connected to the locking hole, and the tail end of the locking seat is connected with a locking spring and a spring seat. One end of the clamp rod head is symmetrically provided with two disassembly grooves, which are two clockwise distributed L-shaped opening grooves. The other end of the clamp rod head is provided with two waist-shaped sliding grooves, and the convex shafts can be slidably installed in the disassembly grooves of the clamp rod head.
[0007] In the aforementioned adjustable uterine lift device, a handle base is connected to the handle, and the clamp rod base is fitted inside the handle base. A locking clip is installed on the handle base to lock the clamp rod base, which is located at the other end of the clamp rod. The handle and the handle base are connected by a fixing pin. The handle base has a row of adjustment slots, and the handle has a buckle button. The buckle button is engaged with any of the adjustment slots to control the angle adjustment of the operating head.
[0008] In the aforementioned adjustable uterine lifter, the number of adjustment slots is five, namely 0° position, 30° position, 45° position, 60° position and 75° position.
[0009] In the aforementioned adjustable-angle uterine lifter, a ball seat is provided inside the handle, and the round end of the ball pull rod is installed inside the ball seat, allowing the round end of the ball pull rod to rotate within the ball seat; a spring is provided below the buckle button.
[0010] In the aforementioned adjustable angle uterine lifter, a support sleeve that can rotate around the clamp bar is fitted on the outside of the clamp bar. A uterine lifter cup is provided on the front side of the support sleeve, a positioning sleeve is provided on the upper surface of the uterine lifter cup, a support is provided on the rear side of the support sleeve, and a baffle is provided on the front side of the support.
[0011] Compared with the prior art, this utility model has an adjustment slot on the handle base and a buckle button on the handle. The buckle button moves within the adjustment slot, which drives the ball joint rod to move back and forth. The ball joint rod pulls the control head to tilt up at the corresponding angle. The design is ingenious and the operation is convenient.
[0012] Furthermore, a spring is provided on the lower side of the buckle button, which locks the buckle button in either of the adjustment slots.
[0013] Furthermore, by setting a convex shaft on the clamp seat, setting a groove on the locking seat to cooperate with the convex shaft, and setting a disassembly and assembly groove on the clamp head, the convex shaft can be slidably installed in the disassembly and assembly groove of the clamp head, so as to quickly disassemble and assemble the ball head pull rod and complete the disassembly and sterilization of the instrument.
[0014] Furthermore, the support sleeve fitted on the outside of the forceps bar can rotate 360° around the forceps bar, and the support sleeve is equipped with a baffle to block blood and other liquids during surgery, making it easier for doctors to operate.
[0015] In summary, this utility model has the advantages of adjustable angle and automatic angle locking, and is easy to assemble and disassemble, convenient for doctors to operate, and can rotate 360° and feed forward and backward. Attached Figure Description
