Detailed Description

Embodiments of the present invention will now be described with reference to the accompanying drawings.

Example 1

The specific embodiment of the utility model is shown in fig. 1 to 4, and an incision retracting fixator comprises an inner snap ring 1, an outer snap ring 2 and a pipeline 3; the inner snap ring 1 is connected with one end of the pipeline 3, and the other end of the pipeline 3 is connected with the outer snap ring 2. In this embodiment, the outer snap ring 2 is a combined structure in which two rings are stacked up and down, and can provide a more stable supporting manner, and meanwhile, compared with the transition fit of the sealing cap 4, the single ring structure has better sealing performance, and the inner snap ring 1 is a single ring structure, so that the relative structural hardness is small, and the abdominal wall tissues and fascia in the abdominal cavity are prevented from being damaged.

Incision retractor fixer outer snap ring 2 diameter is greater than 1 diameter of interior snap ring, 1 diameter of interior snap ring is greater than 3 diameters of pipeline. In the embodiment, the diameter of the outer snap ring 2 is larger than that of the inner snap ring 1, so that a larger moving range is provided for operation of surgical instruments in vitro, the diameter of the inner snap ring 1 is larger than that of the pipeline 3, the moving range of the instrument is larger than that of the pipeline 3 with the similar wound size, and abdominal wall tissues and fascia are prevented from being damaged.

The outer snap ring 2 is of a hollow structure, and a metal ring 21 is arranged in the outer snap ring. The inner snap ring 1 and the outer snap ring 2 are made of polyurethane, and the pipeline 3 is made of polyurethane or silicon rubber. The metal ring 21 arranged in the outer snap ring 2 has certain hardness while ensuring that the surgical requirements are met, the structure of the outer snap ring 2 can be reinforced, and a wound can be better supported and protected, and the metal ring 21 is made of Ni-Ti stainless steel wires. Outer snap ring 2 and interior snap ring 1 use polyurethane parcel becket 21 can better agree with and have better resilience with pipeline 3 mutually, and pipeline 3 material adopts polyurethane can with interior snap ring 1 and outer snap ring 2 integrated into one piece, and the poor problem of junction can be solved to the smoothness better, also can adopt medical silicon rubber to save the cost equally.

The incision retraction fixator further comprises a sealing cap 4; the inner side of the sealing cap 4 is provided with a groove 41, and the groove 41 is matched with the outer shape of the outer snap ring 2. The sealing cap 4 can seal the incision retraction fixator when the wound is not inserted into a medical instrument or is idle, so that the internal part of the abdominal cavity is prevented from being infected by external infection. The sealing cap 4 is divided into an S type and a TS type according to different functions, wherein the S type is a common sealing cap, and the sealing cap is only mutually jointed with the outer clamping ring 2 to seal the wound as shown in figure 3; the TS type is a combined sealing cap 4 as shown in fig. 4. the combined sealing cap 4 further comprises a second sealing cap 42 with a relatively smaller diameter at the upper part, which functions to provide smaller sized medical devices through the wound and to ensure sterile conditions.

The inner snap ring 1 and the outer snap ring 2 are connected with the pipeline 3 in a mode of rolling the edge of the pipeline 3. Similar material makes the whole more integrated of incision retractor fixer with the mode that the partial pipeline membrane of turning over is hot to combine, is favorable to the volume production and guarantees its good finishing quality.

Example 2

Example 1 is a height-adjustable incision retractor, and relatively speaking, the soft tube is suitable for different abdominal wall thicknesses, but for people with thinner abdominal walls, the tube stack may cause secondary injury to the wound, so example 2 is a height-adjustable incision retractor, and a suitable height-adjustable incision retractor can be selected according to requirements. Decide high type incision and lead out fixer and all include interior snap ring 1, outer snap ring 2 and pipeline 3, wherein pipeline 3 is the silicon rubber, and the incision that leads out the fixer difference with the height-changing type is that pipeline 3 is stereotyped to thicken and has the support nature, and the diameter of interior snap ring 1, outer snap ring 2 is bigger than pipeline 3, and vertical cross section is the I-shaped.

The working principle is as follows:

the fixed-height incision retracting fixator is installed by firstly pinching a part of an inner snap ring 1 into a long tongue shape, turning up the inner snap ring from a pipeline and clamping the inner snap ring in an outer snap ring 2 to form a state that the inner snap ring 1 and the outer snap ring 2 are overlapped in a crossed mode, at the moment, the inner snap ring 1 is in a downward inclined state, then, the downward inclined end of the inner snap ring 1 firstly enters and props up a wound, so that the inner snap ring 1 is close to the wall of the wound and pushes the inner snap ring 1 to expand gradually in the wound until the inner snap ring 1 is reset and inserted into the incision, and the pipeline 3 and the wound wall are attached and expand the wound; when the operation is finished or the fixed-height incision retraction fixator needs to be replaced, the finger tips or the hooks extend into the disposable incision retraction fixator, a part of the inner snap ring 1 is pulled, the inner snap ring 1 is overturned and taken out of the incision, or the inner snap ring 1 is pushed out of the pipeline 3 to be deformed and taken out.

The installation of the variable-height incision retracting fixator comprises the steps of firstly, flattening an inner clamping ring 1 into a long tongue shape, pushing the long tongue shape into a wound, elastically expanding the inner clamping ring 1 to clamp the inner wall of the incision, then, pinching two positions of an outer clamping ring 2 by two hands to a position where the circle centers can be vertically intersected to form 90 degrees, and continuously shortening a pipeline 3 through outward turning or inward turning so that the radial expansion force of the pipeline 3 is continuously increased until the outer clamping ring 2 can not be turned over again, and finally, the installation is finished when the wound is fully expanded and protected; when the operation is finished or the high-height incision retraction fixer needs to be replaced, the finger tip or the hook tool extends into the disposable incision retraction fixer, a part of the inner snap ring 1 is pulled, the inner snap ring 1 is overturned to be taken out from the incision, or the inner snap ring 1 is pushed out from the pipeline 3 to be deformed to be taken out.

The sealing cap 4 can be slightly sleeved on the external clamping ring 2 of the incision retractor fixer by being slightly expanded by two hands, when the sealing cap needs to be taken down, the two parts of the external clamping ring 2 are pinched until the circle center can be vertically intersected to form a 90-degree position to be buckled out, and the assembling and disassembling mode of the second sealing cap 42 is also the same as that of the sealing cap 4.

The present invention has been described above with reference to the preferred embodiments, but the present invention is not limited to the above-disclosed embodiments, and various modifications, equivalent combinations, which are made according to the essence of the present invention, should be covered.
