Technical Field

[0001] The utility model relates to the technical field of rotary cutting devices, in particular to a closed rotary cutting device for uterine fibroids. Background Art

[0002] Uterine fibroids are benign tumors formed by the proliferation of uterine smooth muscle tissue and are the most common benign tumors in women. When treating uterine fibroids, it is necessary to remove the uterine fibroids surgically. The existing surgical removal of uterine fibroids can be performed using a myoma rotary cutter. However, the existing myoma rotary cutter is usually an open cut when removing uterine fibroids. In this case, the removed myoma tissue is prone to the risk of metastasis, which is not conducive to the patient's recovery. For this reason, we propose a closed myoma rotary cutter for uterine fibroids. Utility Model Content

[0005] The front end of the elastic connecting rod passes through the puncture sleeve and extends to the front end of the puncture sleeve. A limiting ring is provided at the front end of the elastic connecting rod. A sealing sleeve is installed between the inner surface of the puncture sleeve and the outer surface of the tumor crushing rod. The front end of the sealing sleeve is connected to the limiting ring.

[0006] Preferably, a adapter is provided at the rear end of the tumor crushing rod.

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] As attached Figure 1-5 The closed excision device for uterine fibroids shown in the figure comprises a tumor crushing rod 1, a adapter 2 is provided at the rear end of the tumor crushing rod 1, a stripping cavity 3 is provided on the outer surface of the front end of the tumor crushing rod 1, both sides of the outer surface of the stripping cavity 3 are provided with excision openings 4, a drainage cavity 5 is provided inside the tumor crushing rod 1, a sealing plug 6 is inserted through the outlet end of the drainage cavity 5 of the tumor crushing rod 1, a fixing groove is provided at the front end of the tumor crushing rod 1, an endoscope lens 7 is embedded and installed through the inner surface of the fixing groove of the tumor crushing rod 1, a puncture sleeve 8 is sleeved on the outer surface of the tumor crushing rod 1, and elastic connecting rods 9 are installed on the upper and lower parts of the rear end of the puncture sleeve 8.

[0021] The front end of the elastic connecting rod 9 passes through the puncture sleeve 8 and extends to the front end of the puncture sleeve 8. A limiting ring 10 is provided at the front end of the elastic connecting rod 9. A sealing sleeve 11 is installed between the inner surface of the puncture sleeve 8 and the outer surface of the tumor crushing rod 1. The sealing sleeve 11 is made of a medical plastic bag structure. The front end of the sealing sleeve 11 is connected to the limiting ring 10. An isolation ring 12 is provided between the rear end of the puncture sleeve 8 and the adapter 2. Control ears 13 are provided on both sides of the outer surface of the isolation ring 12.

[0022] During operation, the puncture sleeve 8 can first be extended into the patient's uterus through the surgical opening opened in the patient's body. At this time, the tumor crushing rod 1 can be installed and connected with the power supply structure of the uterine rotary cutter through the adapter 2. After the installation and connection of the tumor crushing rod 1 is completed, its front end can be inserted into the puncture sleeve 8 and extended toward the patient's uterus. When the front end of the tumor crushing rod 1 enters the patient's uterus through the puncture sleeve 8, it can be extended toward the patient's uterus by controlling the front end of the elastic connecting rod 9. At this time, when the front end of the elastic connecting rod 9 extends from the puncture sleeve 8 to the outside, its front end can drive the limiting ring 10 to control the sealing sleeve 11 to extend toward the patient's uterus. At the same time, the front end of the elastic connecting rod 9 will curl and unfold toward the outside as it continues to extend outward, thereby driving the limiting rings 10 to unfold each other. When the limiting rings 10 are unfolded, the sealing sleeve 11 can be driven to unfold. At this time, the unfolded sealing sleeve 11 can be used to wrap the patient's uterine fibroids, and when the uterine fibroids are in the wrapped state, resection can be performed.

[0023] At this time, the tumor crushing rod 1 can be driven to rotate by the power supply structure of the uterine rotary cutter. When the tumor crushing rod 1 is in a rotating state, it can be controlled to approach the patient's uterine fibroids, and cooperate with the rotary cutting opening 4 opened at the front end of the tumor crushing rod 1 to rotary cut the entire uterine fibroids into several small pieces. At this time, the uterine fibroids cut into several small pieces will be in a fixed position range under the obstruction of the sealing sleeve 11, thereby avoiding the phenomenon of uterine fibroid tissue diffusion. After the uterine fibroids are removed by rotary cutting, the sealing plug 6 on the tumor crushing rod 1 can be opened. At this time, the drainage cavity 5 opened in the tumor crushing rod 1 can be used to cooperate with the extraction structure of the uterine rotary cutter to complete the extraction of uterine fibroid tissue, thereby completing the rotary cutting operation of the uterine fibroids. When the operation is completed, the sealing sleeve 11 can be controlled to contract by extracting the elastic connecting rod 9, so that it can be synchronously withdrawn from the patient's body along with the puncture sleeve 8.

[0024] In summary: the rotary cutting device can airtightly wrap the uterine fibroids in the patient's body, which is beneficial for fixing the excised fibroid tissue within a specific position range, thereby reducing the risk of metastasis of the fibroid tissue.
