Description

TECHNICAL FIELD

[0001] The utility model relates to medical auxiliary instrument technical field, concretely relates to a uterus lifting fixer. BACKGROUND

[0002] B-lynch suture is a surgical method for treating postpartum hemorrhage caused by uterine inertia, and its surgical principle is to press the uterus through uterine muscle wall suture line, promote the longitudinal compression of the uterus, form effective extrusion on the blood vessels interwoven in the uterine muscle fiber, reduce the blood flow and flow rate of uterine blood vessels, promote uterine vascular embolism and thrombosis, accelerate the closure of blood sinuses, thereby reducing the amount of bleeding during operation. It is a means for controlling bleeding speed and achieving hemostasis by using medical devices to compress the uterus, resulting in compression of uterine wall blood vessels and reduction of bleeding amount. Some scholars apply B-lynch suture to postpartum hemorrhage, late postpartum hemorrhage and prophylactic binding of uterine inversion, and achieve ideal clinical effects.

[0003] Before B-lynch suture is operated, the uterus needs to be manually compressed to evaluate the possibility of successful hemostasis by suture. The effect is often good during manual evaluation, but the effect after actual suture is different. The reason is that the hemostatic effect and complications depend on the degree of mutual extrusion of the uterine muscle layer, that is, the tightness of the suture, which needs to avoid both the suture binding too loose leading to incomplete hemostasis and the suture line pulling too tight leading to uterine ischemia, infection and necrosis. The tightness of the suture depends on the position of the needle during suture, the shape of the uterus, and the quality of the uterine muscle layer compression after pulling the line. In order to maintain the quality of the suture, the assistant needs to manually lift the uterus and maintain it in a specific position and shape during the operation to facilitate suture operation. This requires too high surgical skill of the assistant, which is not conducive to the efficient operation of the suture operation. Therefore, an auxiliary instrument needs to be designed to replace the assistant to complete the intraoperative uterine pulling and fixing operation. SUMMARY

DETAILED DESCRIPTION

[0019] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0020] See also Figure 1 、 Figure 2 As shown, the utility model provides a uterine lifting fixator, including a fixing frame, the fixing frame includes a left frame, a right frame and a cross beam connecting the left frame and the right frame; wherein, the left frame includes two left support rods 1 rotatably connected in an "X" shape, the right frame includes two right support rods 2 rotatably connected in an "X" shape, and the cross beam includes two parallel cross beams 3, and the left and right ends of each cross beam 3 are respectively connected to the top of a left support rod 1 and a right support rod 2; the lower middle parts of the two left support rods 1 are connected by a left spring 4, and the lower middle parts of the two right support rods 2 are connected by a right spring 5, the rotation connection point of the left frame is located at the upper middle part of the left support rod 1, and the rotation connection point of the right frame is located at the upper middle part of the right support rod 2. Under normal circumstances, the left spring 4 and the right spring 5 are both in a pre-tightened state to prompt the two cross beams 3 to approach each other.

[0021] Through the targeted design of the uterine lifting and fixation device, the fixation frame can be set up and fixed directly above the surgical site during use. After the uterine body is pulled up, the crossbeam at the upper end of the fixation frame is opened to open the two crossbeams. The uterine body is partially introduced between the two crossbeams and then the crossbeams are released. Under the elastic reset force of the left spring and the right spring, the two crossbeams approach and clamp the uterine body X, so as to achieve the purpose of continuously and stably lifting and fixing the uterine body, making it easier to expose the lower end of the uterus to be sutured, which is beneficial to improving the success rate of uterine suture surgery.

[0022] As one example, in the present application, at least one set of relatively arranged clips 6 for lifting and fixing the uterus is installed on the crossbeam 3. The clips 6 are installed one-to-one on the crossbeam 3. A design of multiple sets of clips is used to clamp and fix the uterine body instead of using the crossbeam 3 to clamp directly. The clips 6 can be designed as replaceable medical consumables, which can be used once and can be directly disassembled and discarded as medical waste after the operation.

[0023] According to one embodiment of the present invention, the clip 6 comprises a sleeve portion 6a, an extension portion 6b, and a clamping portion 6c, connected sequentially from top to bottom. The sleeve portion 6a is designed to be secured to the crossbar 3. The extension portion 6b is in the form of a rectangular sheet, and the clamping portion 6c is in the form of a short cylinder. In this design, the inner wall of the sleeve portion 6a provides good friction. The sleeve portion can be made of elastic rubber or plastic. Accordingly, the crossbar 3 can be made of stainless steel or hard plastic with a friction-rippling surface, ensuring that the sleeve portion 6a is securely secured to the crossbar 3. As another example, the sleeve portion 6a and the crossbeam 3 are both plastic parts, and there is a set threshold friction force between the inner wall of the sleeve portion 6a and the outer wall of the crossbeam 3, which have a damping effect on each other, so that the sleeve portion 6a can be rotated to any position relative to the crossbeam 3 and then hover. This design requires a force exceeding the set threshold friction force to rotate the sleeve portion 6a. After adjustment, the clip 6 is still stably mounted on the crossbeam 3 and is not easy to loosen. The orientation angle and clamping position of the clip 6 can be adjusted accordingly according to the azimuth and position that need to be fixed when the uterus is sutured during surgery.

[0024] Preferably, a detachable medical silicone cap 7 is provided on the outer side of the clamping portion 6c, and the length of the medical silicone cap 7 is greater than the clamping portion 6c. In this design, the medical silicone cap 7 is used as a replaceable medical consumable, which is non-irritating, non-toxic, and has no allergic reaction to human tissue, and has very little body rejection reaction. It can avoid damage to the uterine body as much as possible when it contacts the uterine body. As a consumable, it is easy to disassemble and assemble, and has low cost.

[0025] According to an example of the present invention, the lower ends of the left support rod 1 and the right support rod 2 are provided with anti-roll tubes 8 that are vertically connected and arranged outward. This design can increase the bottom support stability of the fixing frame and also increase the parts that can be fixed at the bottom. During preoperative preparation, the fixing frame can be further better fixed at multiple points to prevent tipping during surgery.

[0026] According to an example of the present invention, the upper sections of the left support rod 1 and the right support rod 2 are provided with a plurality of adjustment holes 9 arranged at equal intervals along the length direction, and the cross beam 3 is adapted to be inserted and fixed in different adjustment holes 9 to adjust the fixed height of the cross beam 3.

[0027] As another feasible design form, the crossbeam rod 3 includes a short rod, a long rod and a double-headed adjustment sleeve for connecting the short rod and the long rod. The left end of the short rod is fixed on the left bracket, and the right end of the short rod is provided with an external thread. The right end of the long rod is fixed on the right bracket, and the left end of the long rod is provided with an external thread. The two ends of the double-headed adjustment sleeve are respectively threadedly connected to the short rod and the long rod, and the two ends of the double-headed adjustment sleeve are respectively provided with matching internal threads. When the double-headed adjustment sleeve is rotated forward, the short rod and the long rod move away, forcing the entire crossbeam rod 3 to grow. When the double-headed adjustment sleeve is rotated backward, the short rod and the long rod move closer, forcing the entire crossbeam rod 3 to shorten. This design is more convenient when the width of the entire fixed frame needs to be temporarily adjusted.
