Detailed Description

Referring to fig. 1 and 2, the invention relates to a patch placing device, which comprises a central seat 1, wherein a plurality of bendable unfolding wings 2 are arranged around the central seat 1, elastic elements 3 for resetting the unfolding wings 2 are arranged at the joints of the unfolding wings 2 and the central seat 1, and fixing parts are arranged on the unfolding wings 2 and can be used for detachably fixing one corner of a patch.

When the patch is used specifically, the patch needs to be trimmed to the required size, and then, a plurality of points on the peripheral edge of the patch are fixedly connected with the exhibition wing 2. During the operation, earlier with power to draw in exhibition wing 2 in, confirm the orientation after with this device to incision depths extraperitoneal clearance propelling movement from patient's belly incision, treat that exhibition wing 2 gets into the peritoneum after the clearance before completely, use the exhibition wing 2 of the appropriate adjusting device of long tweezers for the patch is fully flattened. Finally, the connection between the wings 2 and the patch is detached, the patch is left in the extraperitoneal space, and the device is withdrawn from the extraperitoneal space and the incision.

As a preferred embodiment of the present invention, the center base 1 and the exhibition wing 2 are integrally made, the connection portion between the center base 1 and the exhibition wing 2 is made of an elastic material, the center base 1 and the exhibition wing 2 can be integrally made by an injection molding process, and the elastic material enables the exhibition wing 2 to have a bending capability.

As a preferred embodiment of the invention, the elastic material is medical silica gel, so that the cleanness of the elastic material in the operation process can be kept.

As a preferred embodiment of the present invention, one side of the wing span 2 is provided with a reinforcing rib 5 for increasing strength to maintain the shape of the wing span 2 and to maintain the elasticity of the wing span 2.

As the preferred embodiment of the invention, the number of the exhibition wings 2 is four, the four exhibition wings 2 are circumferentially distributed around the center seat 1 at equal angles, and the four exhibition wings 2 respectively fix the four corners of the edge of the patch, thereby ensuring the efficiency and the flattening effect in the flattening process.

As a preferred embodiment of the invention, the fixing part comprises a plurality of through holes 6 which are arranged on each exhibition wing 2 and used for threading, medical wires are arranged in the through holes 6 in a penetrating way, and a wire clamping block 7 is arranged on the center seat 1. In the operation preparation stage, the medical thread penetrates through the fixing point of the edge of the patch, then the medical thread is wound in the through hole 6, the edge of the patch is fixed near the through hole 6 by the medical thread, and then the two thread tails are pulled out and are clamped in the thread clamping block 7. During operation, after the patch is completely flattened, the medical thread can be cut off by using the scissors, and the cut medical thread is pulled out, so that the patch can be separated from the unfolding wing 2, the process is rapid, the operation is simple, the infection can be effectively avoided, and the operation time can be shortened.

As a preferred embodiment of the invention, one side of the through hole 6 is provided with a rectangular notch 8 which is convenient for wiring, and the medical line can directly enter the through hole 6 from the rectangular notch 8, thereby simplifying the threading operation and reducing the threading time consumption.

As a preferred embodiment of the present invention, the through holes 6 are arranged in a row, two rows of through holes 6 are symmetrically arranged on each wing 2, specifically, the through holes 6 arranged in a row make the through holes 6 on each wing 2 of the patch placing device selectable, and when in use, the through holes 6 can be selected according to the size of the patch, thereby increasing the application range of the device.

As a preferred embodiment of the invention, the central seat 1 is provided with a dial 9 for positioning the position of the patch in the middle, and after the device enters the extraperitoneal space, a user can judge the position of the patch in the extraperitoneal space through the dial 9, so as to adjust the position of the patch until the position of the patch meets the surgical requirements.

As the preferred embodiment of the invention, the center seat 1 is provided with the hinge hole 10, the hinge hole 10 is detachably hinged with the handle 11, a user can hold the handle 11 for operation, the operation is more convenient, and the handle 11 can rotate, so that the adaptability is improved.

When the tension-free anterior peritoneal repair of the indirect inguinal hernia or the direct inguinal hernia is performed, the inguinal region is firstly cut layer by layer, and after the hernia sac is dissociated, the anterior peritoneal space is fully dissociated.

The patch is tightly attached to the device, the patch and the device can be trimmed to a proper size as required, the tail end of the exhibition wing 2 is sewed in a U shape corresponding to the outer edge of the patch, and the two ends and the tail end of the two ends are pulled to the thread clamping block 7 through the through hole 6 and fastened. The four corners of the patch are fixed by the same method. The handle 11 is hinged to the central seat 1.

After sufficient dissociation of the preperitoneal space, sufficient hemostasis was obtained and no active bleeding was examined. The direction and the position of the patch are determined, and after the patch fixed on the patch device is checked to be stable, the handle is held by hand to push the device center base 1 to the abdominal cavity side. After the spreading wings 2 completely enter the preperitoneal space, the long forceps properly adjust the spreading wings 2 of the device, so that the patch is fully flattened. One of the two lines on the surface of each exhibition wing 2 is cut off and pulled out slightly. The forceps are firstly protected from the inside and the bottom and are slightly withdrawn from the device between the two wings 2. The transverse fascia ventral fascia was sutured and the remaining layers were sutured.

The patch placing device can obviously shorten the operation time, fully flatten various types of patches, ensure the treatment effect, prevent complications such as relapse and hydrops, reduce the pain of patients and has higher popularization value.

The invention is not limited to the above embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
