Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a laparoscopic uterine fibroid crushing and collection device. Background Art

[0002] Uterine fibroids are benign tumors, but their benign or malignant nature can only be confirmed based on postoperative pathological examination. Currently, minimally invasive laparoscopic surgery has become the mainstream surgical method. During laparoscopic myomectomy, the uterine fibroids need to be excised and crushed before they can be removed from an abdominal incision of approximately 1-2 cm in length. The excising and crushing of uterine fibroids can easily cause tissue splashing, and there is a risk of tumor dissemination. If the postoperative pathology indicates a malignant tumor, it will cause tumor dissemination and increase the tumor stage.

[0003] Existing uterine fibroid removal devices cannot fully encapsulate and collect uterine fibroids. Moreover, huge uterine fibroids need to be gradually removed by rotary cutting and crushing and multiple in and out of the abdominal wall incisions, which prolongs the operation time and increases the surgical risk and postoperative recovery time of patients. Most importantly, the rotary cutting and crushing process is extremely easy to cause tissue splashing, and there is a risk of tumor dissemination, which greatly increases the discomfort time and psychological burden of patients.

[0004] Therefore, there is an urgent need for a laparoscopic uterine fibroid crushing and collection device to solve the above-mentioned problems. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0021] Please refer to Figure 1-2 The present embodiment provides a laparoscopic uterine fibroid crushing and collecting device, which includes a collecting tube 1, a tube mouth of the collecting tube 1 is provided with an annular groove 4, a coating film 2 is provided in the annular groove 4, and the coating film 2 is arranged in an annular shape; an annular bag 3 is provided at one end of the coating film 2, and the annular bag 3 is provided with a filling tube; a filling tube 7 is provided in the collecting tube 1, and the filling tube 7 is connected with the annular bag 3, and a negative pressure tube 8 and a crushing mechanism are provided in the collecting tube 1.

[0022] The existing uterine fibroid removal device cannot fully encapsulate and collect uterine fibroids, and it needs to go in and out of the abdominal wall incision many times to gradually remove them, which takes a long time and has a high risk of surgery. The present invention sets a collection tube 1. During the insertion of the collection tube 1, the coating film 2 set on the collection tube 1 is in the annular groove 4. When the collection tube 1 reaches the approximate position, the medical staff fills the annular capsule 3 through the filling tube. The annular capsule 3 is formed to open the coating film 2 to ensure that the uterine fibroids are covered, which effectively ensures that the cutting and crushing of the fibroids during the operation is carried out normally to avoid scattering; at the same time, the medical staff can crush and remove the uterine fibroids through the crushing mechanism and the negative pressure tube 8 set in the collection tube 1. The uterine fibroids are withdrawn together with the collection tube 1, which effectively avoids the uterine fibroids from scattering.

[0023] In some embodiments of the present invention, at least three annular sacs 3 are arranged at intervals, including a first annular sac 133, a second annular sac 143, and a third annular sac 123. Corresponding liquid filling columns 5 are respectively arranged on the first annular sac 133, the second annular sac 143, and the three annular sacs 3. The liquid filling columns 5 are communicated with the filling tube 7. The multiple annular sacs 3 provided enable medical staff to select the number of filled annular sacs 3 according to the size of the tumor, and support to form a covering film 2 shape relatively adapted to the size of the tumor. The diameters of the first annular sac 133, the second annular sac 143, and the three annular sacs 3 gradually increase. Specifically, it is possible to choose to fill only the first annular sac 133 and the corresponding liquid filling column 5 to make it form a smaller shape for wrapping; if the tumor is larger, the second annular sac 143, the three annular sacs 3, and the liquid filling column 5 can be filled now to enable it to perform covering.

[0024] In some embodiments of the present invention, multiple liquid filling columns 5 are evenly dispersed around the covering film 2. The evenly dispersed multiple liquid filling columns 5 enable the fully filled multiple liquid filling columns 5 to ensure that the multiple first annular sacs 133, the second annular sacs 143, and the three annular sacs 3 make the covering film 2 form a frustum shape with a consistent axis, which can better cover the tumor.

[0025] In some embodiments of the present invention, the liquid filling column 5 is made of an elastic material. The liquid filling column 5 made of an elastic material enables it to well control the position of the corresponding annular sac 3 before and after filling, and pull it back into the annular groove 4 when shrinking for easy entry and exit.

[0026] In some embodiments of the present invention, a tightening ring 6 is arranged inside the annular sac 3, and the tightening ring 6 is made of an elastic material. The arrangement of the tightening ring 6 enables it to tighten and contract to cooperate with negative pressure to cover the tumor when the annular sac 3 is not fully filled.

[0027] In some embodiments of the present invention, the crushing mechanism includes a control rod 11. A crushing cutter head 10 is arranged at the top of the control rod 11, and a collecting hopper 9 is arranged at the top of the negative pressure tube 8; the control rod 11 passes through the collecting hopper 9 and is slidably connected with the collecting hopper 9. The arrangement of the collecting hopper 9 can better perform negative pressure adsorption on the tumor to increase the removal efficiency. An outlet is arranged at the top of the collecting tube 1, and the arrangement of the outlet effectively ensures that the surgical field will not be affected by body fluids during the operation. It can be understood that the crushing cutter head 10 can be selected with a common structure on the market. In summary, the embodiment of the present invention provides a laparoscopic uterine fibroid crushing and collection device, which includes a collection tube 1, a tube mouth of the collection tube 1 is provided with an annular groove 4, a coating film 2 is provided in the annular groove 4, and the coating film 2 is arranged in an annular shape; an annular capsule 3 is provided at one end of the coating film 2, and the annular capsule 3 is provided with a filling tube; a filling tube 7 is provided in the collection tube 1, and the filling tube 7 is connected with the annular capsule 3, and a negative pressure tube 8 and a crushing mechanism are provided in the collection tube 1. The present invention arranges the collection tube 1, and during the insertion process of the collection tube 1, the coating film 2 arranged on the collection tube 1 is in the annular groove 4. When the collection tube 1 reaches the approximate position, the medical staff fills the annular capsule 3 through the filling tube, and the annular capsule 3 is formed to open the coating film 2 to ensure that the uterine fibroid is covered, which effectively ensures that the cutting and crushing of the fibroid during the operation is carried out normally to avoid scattering; at the same time, the medical staff can crush and remove the uterine fibroid through the crushing mechanism and the negative pressure tube 8 arranged in the collection tube 1, and the uterine fibroid is withdrawn together with the collection tube 1, which effectively avoids the uterine fibroid from being scattered.
