Technical Field
[0001] The utility model relates to a medical device, in particular to a special peeling and stretching device for facial skin. Background Art
[0002] In order to achieve good postoperative results, the current minimally invasive facial facelift surgery requires first cutting the skin, peeling the facial skin, and then stretching the deep tissue to fully expose the surgical field and facilitate subsequent SMAS fascia layer operations. Currently, skin stretchers are mostly used in orthopedic and chest surgeries. They are large in size and there are no skin peeling and stretching devices dedicated to minimally invasive facial surgeries. Therefore, doctors now use scissors to separate the skin during surgery. After the skin is separated, they use nose retractors and other retractor devices to pull the skin apart to expose the underlying tissue for subsequent tightening of the SMAS layer tissue and other operations. This poses the following problems:
[0003] 1. The scissors are sharp and do not fit the facial skin, which can easily damage important nerves and blood vessels in the face.
[0004] 2. The field of view of minimally invasive facial surgery is small, so the skin needs to be pulled apart. However, due to the lack of dedicated retractor equipment, doctors often use nasal retractors. However, these retractors are too narrow and short to expose deep tissues, which seriously affects the doctor's operation.
[0005] 3. During the operation, the assistant needs to pull the facial skin and soft tissue upwards, and it is difficult for the hand to find a fulcrum, which affects the stability of the hand and thus affects the operation of the surgeon. Summary of the invention
[0006] The purpose of the utility model is to provide a facial skin peeling stretcher that solves the above problems, can fit well with facial skin, is not easy to damage facial nerves and blood vessels, and is convenient for doctors to peel and pull the skin.
[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is such a facial skin peeling and stretching device, comprising two halves, the middle part of the halves is hinged, the middle part to one end is a stretching arm, and the middle part to the other end is a handle;
[0008] The two spreading arms are rod-shaped and can fit together. When fitted together, the two halves form a Y shape as a whole. The opening and closing angle of the two spreading arms is 0°-30°.
[0009] An end of the spreading arm away from the middle is provided with a spreading head, the spreading head is an isosceles triangle, the three corners are all rounded, and the middle of the bottom edge is fixedly connected to the spreading arm. When the two spreading arms are fitted, the planes of the two spreading heads are opposite and fitted, and the side of the spreading heads away from each other protrudes outward in an arch shape;
[0010] An elastic device for spreading the two handles is arranged between the two handles, and a limiting device for controlling the spreading angle of the two handles is also arranged between the two handles.
[0011] Preferably, the elastic device comprises two elastic sheets, one end of the two elastic sheets is fixed to the inner wall of the handle, and the other end is clamped, and the two elastic sheets are V-shaped as a whole.
[0012] Preferably, the limiting device comprises a bolt and a limiting nut, the bolt being located at one end of the two handles away from the middle, one end of the bolt being fixed to the inner wall of one handle, and the other end passing through the other handle, the limiting nut being located on the outside of the handle and cooperating with the bolt thread, and the other handle being provided with a through hole for the bolt to pass through.
[0013] Preferably, the length of the spreading arm is 100mm-140mm, the length of the handle is 60mm-100mm, and the outer surfaces of the half bodies are rounded.
[0014] Compared with the prior art, the utility model has the advantages of: designing a facial skin peeling and stretching device specifically used in facial facelift surgery, filling the technical gap of no dedicated skin peeling and stretching device for this surgery.
[0015] (1) Easy to peel off the gap: The tip of the support head is smooth and blunt. The tip can be inserted into the gap to easily separate the gap between the subcutaneous tissue and the SMAS layer.
[0016] (2) Protection of blood vessels and nerves: The tip is smooth and can make important blood vessels and nerves slide aside when they are touched during the peeling process, making them less likely to be damaged.
[0017] (3) It can stretch the facial tissue and provide a good field of vision and surgical field: After the required range of peeling is completed during the operation, the expansion head can reach the required further operation position, stretch the facial tissue, and allow the surgeon to more conveniently perform operations such as tightening the SMAS layer tissue within a relatively larger field of vision.
[0018] (4) The degree of retraction can be adjusted to make the surgical field wider and clearer, greatly facilitating the surgeon's operation.
[0019] (5) Good stability: Stability after dilation during surgery is very important for the surgeon's operation. After dilation of the facial tissue, a nut is used to fix the dilation range. The assistant can gently hold the instrument, and the hand can easily find the fulcrum, which greatly improves stability. BRIEF DESCRIPTION OF THE DRAWINGS
