Embodiment 1

[0035] A specific embodiment of the present invention discloses a longitudinally adjustable and finger-to-skin expansion device, which includes a first expansion bag 1, a second expansion bag 2, a puncture top 3, a puncture outer shell 4, and a sac wall release inner shell 5, Anchor wire 6, inflatable bag 7 and connecting port 8.

[0036] Wherein, the connecting port 8 is a multi-cavity ventilation structure, such as figure 2 As shown, it is specifically a circular three-plane stepped multi-chamber ventilation structure, each plane is provided with ventilation holes for the ventilation of each chamber, and each step divides an air chamber. The connecting port 8 of the present invention has three ventilation chambers, specifically , the first vent hole 9 is provided on the first chamber to ventilate the first dilation bag 1, the second vent hole 10 is provided on the second chamber and the inflatable bag 7 can be ventilated through the second vent hole 10, and the third vent h...

Embodiment 2

[0054] This embodiment provides a method for expanding the combined finger skin of a patient using the longitudinally adjustable finger-jointed skin expansion device in the above-mentioned embodiment 1. The expansion method of this embodiment includes the following steps:

[0055] Step 1. Implant the conical skin expansion device with a cylindrical tip into the skin that needs to be expanded;

[0056] Step 2. Inflate the inflatable bag 7 through the second ventilation hole 10 provided on the second cavity of the connecting port 8, and the shape of the inflatable bag 7 after inflation is as follows: figure 1 As shown, the inflation of the inflatable bag 7 is completed and the puncture top 3 is pushed away to separate the puncture top 3 from the puncture shell 4 .

[0057] Step 3: Start the rigid dilatation period, inflate the first expansion bag 1 through the first ventilation hole 9 of the first cavity of the connecting port 8, and ventilate the first cavity to make the first ...

Abstract

The invention relates to a longitudinally adjustable syndactylia skin expansion apparatus and belongs to the field of medical surgery, solving the problem of large skin tension and more skin transplantation in the course of operation due to the lack of skin expansion in the prior art. An inflatable capsule, a first expansion capsule and a second expansion capsule are connected through a multi-cavity ventilation pipe port which can have the capsules ventilated independently, the inner wall of the hollow cylindrical inflatable capsule is connected with a first cavity wall while the outer wall of the same is connected with a second cavity wall, the bottom of the first expansion capsule is connected with the second cavity wall, the second expansion capsule is connected with a third cavity wall, the inflatable capsule is located in the first expansion capsule, the first expansion capsule is located in the second expansion capsule, and an anchor line is further arranged to lead the puncture top to displace to adjust the expansion length and width of the expansion capsules. The skin expansion apparatus adopts the stage type expansion, rapid expansion of large tension in hard expansion period and gradual expansion in the soft expansion period are achieved, the expansion length and width can be adjusted, and good expansion effect is realized.

Description

technical field [0001] The invention relates to the field of medical surgery, in particular to a longitudinally adjustable and finger-to-skin expansion device. Background technique [0002] Syndrome operation is one of the most common operations for congenital hand deformities. It mainly includes three steps: finger web reconstruction, separation of fingers and lateral coverage of fingers. During the operation, the skin tension is high and the application of skin grafting cannot be ignored. Many surgeons seek to reduce the application of skin grafts and reduce the incidence of complications. Skin expansion and external fixation techniques have the risk of nail bed displacement due to external distraction. There is a lack of a method that can achieve easy insertion and opening. , a multifunctional implantable skin dilator with controllable pressure. Contents of the invention [0003] In view of the above-mentioned analysis, the present invention aims to provide a verticall...
