Problems solved by technology

The choice of flap incision position will directly affect the success of flap transplantation, but for junior dermatologists, due to lack of clinical experience, the following problems often occur in flap transplantation: the choice of incision position Inaccurate, or improperly shaped incisions, or improperly sized incisions
The above problems make the postoperative outcome less desirable or uncontrollable

Embodiment 1

[0040] Embodiment 1 skin flap operation guiding device

[0041] Such as Figure 1-Figure 6As shown, the flap surgery guiding device of the present invention includes a wound site three-dimensional image reconstruction device and a projection device, and the three-dimensional image reconstruction device includes a fixed frame, a controller, an arc-shaped track 1, and a The camera 2, the driving mechanism that drives the camera 2 to move on the arc-shaped track 1, the arc-shaped track 1 is arranged on a fixed frame, specifically, the fixed frame includes a telescopic column A33 and a chassis 34, the The column A is arranged on the chassis, and the bottom of the column A33 can be slidably matched with the chassis 34; the controller is respectively connected with the camera 2, the projection device and the driving mechanism, and the three-dimensional image reconstruction device is used to scan the wounded part of the patient, And generate skin flap incision shape and path informa...

Embodiment 2

[0046] Embodiment 2 Guidance method of skin flap surgery guide device

[0047] The guiding method of the flap operation guiding device in the present embodiment comprises the following steps:

[0048] S1) Scan the patient's wound site through the camera, and input the patient's wound site and peripheral site information to the controller, and the controller reconstructs a two-dimensional image through the flap segmentation algorithm;

[0049] S2) The controller stores big data information and flap incision and path selection algorithms based on various two-dimensional images to generate the flap incision shape and path, and the controller is based on the big data information and the flap incision and path selection algorithm Draw the shape and path of the flap incision;

[0050] S3) The shape of the flap incision and the path information are projected on the wound site and surrounding areas in the form of light through the projection device, so as to guide the surgeon correct...

Abstract

The invention discloses a flap surgery guiding apparatus and a guiding method. The flap surgery guiding apparatus of the invention comprises a wound part three-dimensional image reconstruction apparatus and projecting device; the three-dimensional image reconstruction apparatus comprises a controller, an arc-shaped track, a camera arranged on the arc-shaped track, and a driving mechanism for driving the camera to move on the arc-shaped track. According to the flap surgery guiding apparatus of the invention, after the wound of a patient is analyzed, a flap cutting scheme is provided for a surgeon by means of ray casting guiding, thereby improving the surgery quality of the surgeon. According to the guiding method of the flap surgery guiding apparatus of the invention, based on an image recognition and machine learning technology, a flap selection path can be provided for flap transplantation surgery, so that an optimal flap design is implemented, relatively good prognosis is achieved, and beneficial reference can be provided for a junior doctor during the flap transplantation surgery.

Description

technical field [0001] The invention relates to a skin flap operation guiding device and a guiding method. Background technique [0002] Skin flaps are also called pedicled skin grafts. Flaps are chunks of skin and underlying tissue that can be transferred from one part of the body to another. During the transfer process, one or two pedicles need to be connected, or they can not be connected temporarily, and vascular anastomosis is performed after transplantation. The blood transport and nutrition of the skin flap completely depend on the supply of the pedicle in the early stage. About 3 weeks after the skin flap has healed at the skin graft site, a new blood circulation system is gradually established. At this time, the pedicle can be cut off, and the flap transplantation process is over. [0003] After the flap is transferred, due to the full-thickness skin and rich fat tissue, its shrinkage is much smaller than that of free skin grafting, and it can withstand external ...
