Description

Intestinal wall incision fixer

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to an intestinal wall incision fixer.

Background

In recent years, minimally invasive endoscopic surgery and small incision surgery are rapidly developed, surgical instruments enter, operate and take out tumors and damaged tissues in the intestinal wall through the small incision, but due to the fact that the intestinal wall has irregular peristaltic contraction, the incision position cannot be fixed, mucous membranes on the inner side of the intestinal wall are prone to eversion, and therefore the surgical visual field cannot be fixed in the operation process, and surgical operation is affected.

In the prior art, the drag hooks are usually used for dragging in a plurality of directions respectively, but the mode can not make the incision fully expose the operation visual field, is easy to damage the intestinal wall tissue, can not be realized in the endoscopic surgery, and also makes the operation process complicated,

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide an intestinal wall incision fixer, which can fully expose the incision of the intestinal wall to the operating visual field and fix the visual field, and has convenient use and convenient storage and storage of the equipment.

In order to achieve the above purpose, the utility model adopts the technical scheme that: an intestinal wall incision fixer comprises a polygonal telescopic support frame body and a baffle, wherein the polygonal telescopic support frame body comprises a plurality of support rods, and each support rod is connected end to end through an articulated piece to form a polygonal structure; all be provided with the baffle perpendicularly on every bracing piece the top of baffle is provided with the kink, the kink outwards buckles.

Furthermore, the polygonal telescopic support frame body comprises 6 support rods, and each support rod is connected end to end through a hinge element to form a hexagonal structure; the hexagonal structure of 6 spinal branch vaulting poles is expanded the later tensile equilibrium effect through 6 directions, and the hexagonal structure after expanding has stronger stability, can make the support frame body constitute a firm structure, improves the support performance.

Furthermore, the polygon telescopic support frame body comprises 4 support rods, and each support rod is connected end to end through a hinge piece to form a quadrilateral structure.

Further, the articulated elements include the pivot and the loop forming element that sets up at every bracing piece head and tail end, and the loop forming element cover of adjacent bracing piece is established and is made the bracing piece rotatory along with the pivot on same pivot, and the pivot both ends are provided with the locking cap and guarantee that the loop forming element can not drop. The flexible motion between every bracing piece is guaranteed, and the polygonal structure who encloses through end to end setting bracing piece makes the support frame body form and can carry out flexible structure, the storage and the use of the support frame of being convenient for.

Furthermore, the bending part is of an annular hook-shaped structure, so that the intestinal incision can be conveniently hung on the bending part after being turned outwards, and the intestinal incision is unfolded by the plurality of circumferential bending parts, so that a wide view field is provided for operation.

The beneficial effects of the technical scheme are as follows:

the utility model discloses a with the fixer cover peripheral at the incision of intestines wall, turn up the incision simultaneously the back circumference hang on corresponding kink for the incision can fully expose the operation field of vision, and the field of vision is fixed simultaneously, has improved efficiency and convenience for whole operation process.

The utility model discloses can stretch or shrink, can contract into rectangular form under the unsuitable state, the operating personnel of being convenient for takes and deposits, reduces the space of device and occupies.

Fig. 1 is a schematic structural view of an intestinal wall incision fixator according to the present invention;

fig. 2 is a schematic view of an embodiment of the present invention;

wherein, 1 is the support body, 2 is the baffle, 3 is the bracing piece, 4 is the articulated elements, 5 is the kink, 41 is the pivot, and 42 is the annular member.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further explained below with reference to the accompanying drawings.

In embodiment 1, referring to fig. 1-2, an intestine wall incision fixator comprises a polygonal telescopic support frame and a baffle, wherein the polygonal telescopic support frame comprises a plurality of support rods, and each support rod is connected end to end through a hinge to form a polygonal structure; all be provided with the baffle perpendicularly on every bracing piece the top of baffle is provided with the kink, the kink outwards buckles.

In embodiment 2, the polygonal telescopic support frame body comprises 6 support rods, and each support rod is connected end to end through a hinge element to form a hexagonal structure; the hexagonal structure of 6 spinal branch vaulting poles is expanded the later tensile equilibrium effect through 6 directions, and the hexagonal structure after expanding has stronger stability, can make the support frame body constitute a firm structure, improves the support performance.

Embodiment 3, the flexible support body of polygon includes 4 spinal branch vaulting poles, and every spinal branch vaulting pole encloses into quadrilateral structure through articulated elements end to end.

As the optimization scheme of the embodiment, the hinge piece comprises a rotating shaft and ring-shaped pieces arranged at the head end and the tail end of each supporting rod, the ring-shaped pieces of the adjacent supporting rods are sleeved on the same rotating shaft to enable the supporting rods to rotate along with the rotating shaft, and fixing caps are arranged at the two ends of the rotating shaft to ensure that the ring-shaped pieces cannot fall off. The flexible motion between every bracing piece is guaranteed, and the polygonal structure who encloses through end to end setting bracing piece makes the support frame body form and can carry out flexible structure, the storage and the use of the support frame of being convenient for.

As an optimized scheme of the above embodiment, the bending part is in an annular hook-shaped structure, so that the intestine incision can be conveniently hung on the bending part after being turned outwards, and the intestine incision is expanded by the plurality of circumferential bending parts together, thereby providing a wide view for operation.

For better understanding, the utility model discloses, following is to the theory of operation of the utility model make a complete description:

stretching the support frame body contracted into a long strip shape to form a polygonal annular structure;

sleeving the fixer on the periphery of the incision of the intestinal wall;

the intestine incision is turned outwards and then hung on the bending part, and the intestine incision is unfolded by the plurality of circumferential bending parts together, so that an open view is provided for operation;

after the use, two opposite hinged parts are stretched towards opposite directions, so that the support frame body is contracted into a long strip shape, and the storage is convenient.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
