Abstract

The invention relates to the technical field of surgical operation equipment, in particular to a tumor protection clamp for intestinal malignant tumor operation. The main technical scheme is as follows: the novel protective film clamp comprises two clamps, a protective film and a cross rod, wherein each clamp comprises an opening and closing handle and a semicircular clamp body, the clamps are connected through shafts, the clamps are connected with semicircular steel wires, the lower end opening of each semicircular clamp body is connected with the cross rod and a rubber strip, and the two ends of the protective film are connected with the semicircular clamp bodies. The invention can completely wrap the tumor when the operation of the malignant tumor of the intestinal tract is carried out, avoid the pollution of the operative field and the falling of the tumor body caused by the tumor rupture, block the blood vessel of the intestinal tract, prevent the tumor cell falling caused by the tumor extrusion in the operation from causing the distant metastasis, has very simple and convenient clinical operation, improves the operation efficiency and improves the excision quality of the tumor.

Description

Tumor protection clamp for intestinal malignant tumor operation

Technical Field

The invention relates to a tumor protection clamp for intestinal malignant tumor surgery, and belongs to the technical field of surgical operation equipment.

Background

Most of intestinal tumors found in China clinically are middle and late stages, most of tumors break through a serosal layer and protrude out of the intestinal wall, the principle of tumor resection should be a whole block and non-contact principle, most of clinicians touch the tumors repeatedly in the tumor resection operation at present and do not block blood vessels, tumor cells may fall off and enter the blood vessels to cause distant metastasis, the tumors are not isolated from the outside, or only a layer of glue is coated, the isolation is not thorough, the tumors are often diffused to the abdominal cavity or incision, iatrogenic implantation metastasis is formed, and the long-term curative effect is influenced.

Disclosure of Invention

In order to solve the technical problems, the invention provides a tumor protection clamp for intestinal tumor surgery, which can prevent the tumor from being polluted in the surgical field and the tumor body from falling off due to tumor rupture, block the intestinal blood vessel and prevent the tumor cells from falling off due to tumor extrusion in the surgery to cause distant metastasis. The technical scheme of the invention is as follows:

the utility model provides a tumour protection presss from both sides for intestinal malignant tumor operation, includes two clips, protection film and horizontal pole, the clip including opening and shutting handle and semi-circular clamp, the clip pass through the hub connection, the clip connect semi-circular steel wire, semi-circular clamp lower extreme opening connect horizontal pole, rubber banding, semi-circular clamp is connected at the both ends of protection film.

Furthermore, the cross bar is made of resin.

Furthermore, the protective film is a thin-layer elastic protective film.

The invention has the following beneficial effects: can wrap up the tumour completely when carrying out the operation of intestinal malignant tumour, avoid the tumour to break and cause art field pollution and the tumor body drops, block the intestinal blood vessel simultaneously, can prevent to extrude the tumour cell that the tumour caused and drop and arouse the distant place to shift in the operation, clinical operation is very simple and convenient, has both improved operation efficiency, has improved the excision quality of tumour again. The invention has good application prospect in the field and is worth using and popularizing.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Wherein: 1. a handle is opened and closed; 2. semicircular steel wires; 3. a shaft; 4. a rubber strip; 5. a protective film; 6. a cross bar; 7. a semicircular clip body.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1, a tumor protection clamp for intestinal malignant tumor surgery comprises two clamps, a protection film 5 and a cross rod 6, wherein each clamp comprises an opening and closing handle 1 and a semicircular clamp body 7, the clamps are connected through a shaft 3, the clamps are connected with semicircular steel wires 2, the lower end of each semicircular clamp body 7 is provided with an opening, the cross rod 6 and a rubber strip 4 are connected, and two ends of the protection film 5 are connected with the semicircular clamp bodies 7. The cross bar 6 is made of resin. The protective film 5 is a thin elastic protective film.

The invention discloses a tumor protection clamp for intestinal tumor surgery, which comprises two clamps spliced with each other, a protective film 5 connected with a semicircular clamp body 7, rubber strips 4 at two ends, and two hard resin cross bars connected with the open ends of the clamps. The clamp comprises a handheld part and a semicircular clamp body 7, wherein the handheld part of the opening and closing clamp at the upper end is connected through a shaft 3, the semicircular clamp body 7 is arranged at the lower end of the clamp, and the semicircular clamp body 7 ensures the elasticity of the clamp through two semicircular steel wires 2; the rubber strips 4 are arranged below the clips at the two ends and are used for tightening the intestinal canals at the two ends of the tumor; two parallel hard resin cross bars for clamping mesentery and blood vessel. The diameter of the semicircular clamp body 7 is 6-8 cm, and the opening length is 8-10 cm when the semicircular clamp body is opened. The thin elastic protective film is connected with the arc-shaped clamp body below the semicircular clamp body 7, and the length of the thin elastic protective film is 8-12 cm. The rubber strip 4 is arranged below the semicircular clamp body 7 and is used for tightening the intestinal canals at the two ends of the tumor; two parallel hard resin cross bars with the length of 8-12 cm are used for clamping and blocking mesentery and blood vessels.

The two clamps are used for clamping intestinal walls at two ends of a fixed tumor, the protective film 5 is used for wrapping and covering a tumor body and the surface of the tumor, the protective film 5 prevents tumor cells from falling off to cause abdominal cavity planting and transfer, the rubber strips 4 at two ends are used for tightening intestinal tubes at two ends of the tumor to prevent the tumor cells from migrating to the intestinal tubes at two ends, and meanwhile, chemotherapy medicaments filled into the intestinal tubes near the tumor body are limited to the local part of the tumor. The two parallel hard resin cross bars are used for clamping mesentery and blood vessels supplied by the tumor, and are used for blocking the blood vessels before the tumor is resected, so that the tumor cells are prevented from falling off and flowing back to the blood along the vein to cause liver or whole body planting and metastasis, and the tumor resection principle is better met.

When the device is used, the upper ends of the two clamps are respectively pinched by the left hand and the right hand to open the clamps, the tumor protection clamp and the intestinal wall are in the same direction by taking the tumor body as the center and are placed in alignment with the intestinal wall, the assistant can pull and lift the rubber strip 4 at the same time, and the operation can be completed after the tumor is completely wrapped and the intestinal wall is released. The clinical operation is very simple and convenient, the operation efficiency is improved, and the tumor resection quality is also improved.

The foregoing examples are provided for illustration and description of the invention only and are not intended to limit the invention to the scope of the described examples. Furthermore, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that many variations and modifications may be made in accordance with the teachings of the present invention, which variations and modifications are within the scope of the present invention as claimed.
