Description

Technical Field

[0001] The utility model relates to the technical field of subcutaneous fat minimally invasive surgery equipment, in particular to a skin stretcher. Background Art

[0002] Bromhidrosis is mainly caused by the hypersecretion of the apocrine sweat glands in the armpits. The organic matter in the patient's sweat is decomposed by bacteria on the skin surface to produce unsaturated fatty acids, which emit an odor. It often occurs during the summer hyperhidrosis period, seriously affecting the patient's social interaction and daily life, and increasing his psychological burden.

[0003] The apocrine glands of the armpits are all in the subcutaneous fat layer, located 1.7-3.7 mm below the epidermis, and distributed in the armpit hair area and within 5.0-10.0 mm outside. Therefore, surgical removal of the 4.0-5.0 mm thick subcutaneous fat in the armpit hair area containing the apocrine glands can cure armpit odor.

[0004] At present, the surgeries for treating axillary odor in the prior art include the following: axillary odor fusiform resection, small incision scraping, multiple small incision apocrine pruning and negative pressure aspiration. Axillary odor fusiform resection is to remove the entire axillary skin and part of the subcutaneous fat in all axillary follicles, but the disadvantage is that the wound surface is large. If the tension is too large, it will cause the incision to split and suture multiple times, causing pain to the patient. Small incision scraping is to trim the hair follicles under direct vision, and use a curette to scrape off the remaining subcutaneous tissue, sweat gland tissue and hair follicle tissue. Multiple small incision apocrine pruning is to implement multiple small incisions, use the index finger to push the subcutaneous millet-shaped apocrine glands to the incision site, and push the surrounding fat to the incision site at the same time, and use ophthalmic scissors to remove the relevant tissues. Negative pressure aspiration is to implement undercover peeling in a specific area, and use a liposuction needle to rotate the two sides of the needle hole up and down until all the fat tissue is directly cleaned. However, the above methods all have major disadvantages and cannot achieve effective radical treatment.

[0005] The applicant has creatively developed a skin stretcher-assisted subcutaneous fat high-speed planer minimally invasive axillary odor radical treatment method. The surgical process requires the skin area in the calibrated area of ​​the axillary surgical field to be stretched and lifted, and then the apocrine glands under the skin are removed using a high-speed planer. In order to assist in the operation of this part of the surgery, the applicant has specially invented a skin stretcher that can facilitate the stretching, fixation and lifting of the skin in the axillary surgical field.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0021] See also Figure 1 and 2 In an embodiment of the utility model, the skin stretcher includes a steel cable 1, the working section of the steel cable 1 is bent into a ring-shaped portion, and the two ends of the steel cable 1 are gathered and fixed together by a gathering fixture; the gathering fixture includes a tubular or annular fixing ring 2, and the two ends of the steel cable 1 are slidably gathered in the fixing ring 2.

[0022] The retracting and fixing device also includes a tightening and fixing positioning structure, which includes a tightening bolt 3. A threaded hole 4 is opened on the side wall of the fixing ring 2. The tightening bolt 3 is threadedly installed in the threaded hole 4. The tightening bolt 3 is inserted into one end of the fixing ring 2 to tighten the side wall of the steel cable 1.

[0023] The utility model further comprises a plurality of towel clamps 5 , which are clamped on the side wall of the annular portion of the steel cable 1 in an annular array.

[0024] The method of using this embodiment is as follows:

[0025] Place the curved annular portion of the steel cable 1 around the surgical excision mark range, use several towel clamps 5 to relatively fix the skin and the steel cable 1 according to the pre-marked subcutaneous excision range, and the distance between each towel clamp 5 is about 2-3cm. Then release the steel cable 1 to appropriately expand the annular area. Due to the elastic effect of the steel cable 1 itself, the towel clamp 5 relies on the elastic force of the steel cable 1 to evenly stretch the axillary skin around multiple points, so that the skin of the surgical field is flat and has a certain tension. At this time, the size and shape of the annular portion of the steel cable 1 can be fixed by closing the fixator and rotating the tightening bolt 3 so that the tightening bolt 3 is inserted into one end of the fixing ring 2 to press the side wall of the steel cable 1. Then, lift the steel cable 1 appropriately. At this time, the skin of the surgical field is flat and slightly tensilely moved forward. With the help of an endoscope, it is easier to place a high-speed planer under its skin to cut and remove the sweat glands according to the surgical requirements. Example 2

[0026] See also Figure 3 In this embodiment, an arc-shaped clamping piece 6 is provided in the fixing ring 2, and the inner concave surface of the arc-shaped clamping piece 6 contacts the outer side wall of one of the steel cables 1. The tightening bolt 3 is inserted into one end of the fixing ring 2 to rotate and connect the arc-shaped clamping piece 6.

[0027] Rotating and tightening the bolt 3 can drive the arc-shaped tightening piece 6 to squeeze the two ends of the steel cable 1 in the fixing ring 2 relatively tightly, which is used to fix the size of the ring portion of the steel cable 1 in real time, and prevent the outer surface of the steel cable 1 from being damaged by tightening the bolt 3 after multiple uses, so that burrs or concave parts are generated.

[0028] The remaining structures and usage of this embodiment are the same as those of the first embodiment and will not be described in detail here. Example 3

[0029] See also Figure 4 In this embodiment, an anti-skid rubber pad 7 is provided on the inner wall of the fixing ring 2 that contacts the outer wall of another steel cable 1. The use of the anti-skid rubber pad 7 can further increase the friction force of the steel cable 1 sliding in the fixing ring 2, and can temporarily fix the size of the ring portion of the steel cable 1, which is convenient for flexible adjustment at any time before the final fixation.

[0030] The remaining structures and usage of this embodiment are the same as those of Embodiment 1 or 2 and will not be described in detail here.
