Technical Field

The invention relates to a medical appliance for uterine cavity, in particular to a uterine manipulator for preventing tumor cells from spreading.

Background

The clinical efficacy of laparoscopic surgery for uterine malignancies has become increasingly established and accepted. The principle of malignant tumor surgical treatment is to ensure sufficient surgical range and tumor-free principle; when the uterus is resected by malignant tumor, especially when the uterus is widely resected, the requirement on fine dissection is high, the requirement on the uterine elevator is not only to flexibly swing the uterus in multiple directions and multiple angles, but also to achieve the operation principle of no tumor. In laparoscopic cervical cancer surgery, doctors can lift the uterus with different uterine lifters for convenient operation, the application of the uterine lifters inevitably extrudes cancer tissues, when a cancer focus is large or is positioned in a cervical canal or affects the uterine cavity, the uterine lifting cup or the uterine lifting rod can cause the falling of the cancer tissues, and in addition, CO in the surgery₂The action of pneumoperitoneum may cause the implantation of cancer cells in the pelvic cavity and abdominal cavity, resulting in tumor metastasis.

Disclosure of Invention

Aiming at the technical problems, the invention provides the uterine manipulator which can avoid the shedding and dissociation of tumor cells and prevent the diffusion of the tumor cells.

The technical scheme adopted by the invention is as follows: the utility model provides a prevention tumour cell diffusion lift palace ware, includes that one end can stretch into the pole of lifting palace in palace chamber, should lift the palace pole and be the cavity form, and its one end that stretches into palace chamber seals and is the arc of evagination, sets up the several through-hole with this pole inner chamber intercommunication of lifting palace at this curved tip, it is connected with the vacuum aspiration ware to lift the palace pole other end, and the tumour cell that drops when this vacuum aspiration ware will lift the palace through the negative pressure is followed several through-hole is through lifting palace pole inner chamber suction.

Preferably, one end of the uterus lifting rod extending into the uterine cavity is provided with a storage device capable of storing tumor cells falling off during uterus lifting.

Preferably, the receiving device is made of transparent soft materials, can be folded or unfolded, and is in an umbrella-shaped structure when being unfolded, and the womb lifting rod is located in the center of the umbrella-shaped structure.

Preferably, the storage device is a collapsible or expandable balloon, and the balloon is umbrella-shaped when expanded.

Preferably, a channel is formed in the uterine lifting rod, and gas or liquid is filled into the balloon through the channel.

Preferably, the side wall of the uterine manipulator is positioned at the bottom of the balloon and is provided with a row of suction holes communicated with the inner cavity of the uterine manipulator along the circumferential direction.

Preferably, each suction hole is an inclined hole with a lower outer part and a higher inner part.

Preferably, the lateral wall of the uterine lifting rod corresponding to the upper part of the saccule is provided with a row of accommodating holes communicated with the inner cavity of the uterine lifting rod along the circumferential direction.

Preferably, each of the receiving holes is an inclined hole having a high outer portion and a low inner portion.

According to the scheme, the tumor cells which possibly fall off during uterus lifting are sucked out under the action of negative pressure through the hollow uterus lifting rod and the through hole, so that the falling, dissociative diffusion of the tumor cells are avoided as much as possible. The uterine manipulator is simple in structure and easy to operate, tumor cells are stored thoroughly, and the tumor cell sucking effect is good.

Detailed Description

The invention will now be described in detail with reference to fig. 1, wherein exemplary embodiments and descriptions of the invention are provided to explain the invention, but not to limit the invention.

Referring to fig. 1, the present invention provides a uterus lifting device for preventing tumor cell diffusion, which comprises a uterus lifting rod 1 having one end capable of extending into a uterine cavity, wherein the uterus lifting rod is hollow, the end extending into the uterine cavity is closed and is in an arc shape protruding outward, a plurality of through holes 11 communicated with the inner cavity of the uterus lifting rod are arranged at the end of the arc shape, the other end of the uterus lifting rod is connected with a negative pressure suction device (not shown in the figure), and the negative pressure suction device sucks tumor cells falling off during uterus lifting from the plurality of through holes through the inner cavity 12 of the uterus lifting rod by negative pressure, so that the falling, free diffusion of the tumor cells can be effectively avoided. The invention adopts the arc-shaped uterus lifting rod end part, and when the better uterus lifting effect is ensured, enough space is left between the uterine cavity wall and the uterus lifting rod end part, which is beneficial to negative pressure suction and can prevent the blockage of the through hole.

Preferably, the accommodating device 2 for accommodating tumor cells falling off during uterine lifting is arranged at one end of the uterine lifting rod extending into the uterine cavity, so that the tumor cells which may fall off can be accommodated in a wider range. Specifically, the containing device is made of transparent soft materials, avoids damaging the uterine cavity and obstructing the surgical field, can be folded or unfolded, and is in an umbrella-shaped structure when being unfolded, so that the fallen tumor cells can be contained in the concave part of the umbrella-shaped structure, and the tumor cells are prevented from being transferred; the uterus lifting rod is positioned in the center of the umbrella-shaped structure and can be used for accommodating tumor cells around the uterus lifting position of the uterus lifting rod, so that the tumor cells can be completely accommodated when the uterus is lifted.

The storage device 2 of the present invention is a balloon 21 that can be collapsed or expanded, and the balloon is umbrella-shaped when expanded. Before lifting the uterus, the saccule contracts, so that the uterus lifting rod can conveniently extend into the uterine cavity. A channel 22 is formed in the uterine lifting rod, and gas or liquid is filled into the balloon through the channel, so that the size of the balloon is controlled through the channel in the uterine lifting rod, the structure is simple, and the processing is convenient. Meanwhile, the saccule is made of soft and transparent materials, so that the visual field of the operation is not obstructed, and the uterine cavity is not damaged.

In the implementation process, the side wall of the uterine manipulator is positioned at the bottom of the balloon and is provided with a row of suction holes 13 communicated with the inner cavity of the uterine manipulator along the circumferential direction, so that the tumor cells contained in the concave part of the balloon are ensured to be sucked into the inner cavity of the uterine manipulator. Preferably, each suction hole is an inclined hole with a lower outer part and a higher inner part, so that the tumor cells can be completely sucked into the inner cavity of the uterine lifting rod.

A row of containing holes 14 communicated with the inner cavity of the uterine lifting rod are formed in the lateral wall of the uterine lifting rod corresponding to the upper part of the saccule along the circumferential direction, the containing holes can suck tumor cells, the contracted saccule can be adsorbed on the uterine lifting rod when the saccule is folded, the residual tumor cells contained in the concave part of the saccule are coated by a sealed space, and the tumor cells are thoroughly sucked. Preferably, each accommodating hole is an inclined hole with a high outer part and a low inner part, and the design can ensure that the suction range is wider on one hand and ensure that the saccule is more firmly and tightly adsorbed on the uterine lifting rod when the saccule is folded. In addition, the balloon is obliquely adsorbed through the bottom suction hole and the upper accommodating hole, so that a certain closed space is formed in the middle of the balloon, residual tumor cells can be completely coated in the closed space when the balloon is contracted, and the tumor cell metastasis is effectively prevented.
