Expanded skin flap delayer

Abstract

The invention relates to an expanded skin flap delayer, consisting of a bracket (1) and an expanded air bag (11). The expanded skin flap delayer is characterized in that the bracket (1) consists of a base (2), a telescopic rod (4) and a mechanical arm (6); the mechanical arm (6) is connected with the telescopic rod (4) by a spherical joint (5); the front end of the mechanical arm (6) is provided with a ring (7) which is provided with a small arm (8); one end (8B) of the small arm (8) is provided with a semicircular iron piece (9) which is connected with the small arm (8) by a screw (10); and the diameter of the expanded skin flap is matched with the semicircular diameter of the semicircular iron piece (9). The expanded skin flap delayer has the beneficial effects that a patient can perform preoperative delay of an expanded skin flap at home by self after being instructed by a doctor, and the defects that the traditional operation method has complex process and more complications, and is hard to carry out secondary correction after operation when delaying is carrying out on the expanded skin flap and the like.

Description

technical field [0001] The invention relates to a preoperative delay of an expander to expand skin flaps, in particular to a delayer for expanding skin flaps. Background technique [0002] Currently, there are several main techniques for preoperative delay of dilator-expanded flaps: [0003] 1. Delay in operation is currently the main means of delaying preoperative expansion of flaps with dilators. The operation process can be briefly described as follows: (1) Determine the size of the flap to be transferred; (2) Keep the pedicle, incise the skin and subcutaneous tissue along the periphery of the flap, and ligate the main blood vessel branches along the way; (3) Suture the incision in situ. Open flap. Its purpose is to cut off the other blood supply sources of the flap except the pedicle through surgical incision, thereby creating a local ischemic and hypoxic environment, promoting the expansion of blood vessels in the pedicle and the growth of new capillaries. Therefore,...

AI Technical Summary

Problems solved by technology

The main disadvantages are as follows: (1) Since the incision of the delayed operation will be used as the surgical incision for the second-stage flap transfer, it is necessary to make a comprehensive correction on the size, pedicle position, and width of the flap to be transferred before the delayed operation. Judgment, but often the design of the flap needs to be adjusted during the operation according to the blood supply of the flap, the tension of the flap, the defect area and other factors, that is, it is difficult to make an accurate design before the delayed operation, so the delayed operation increases to a certain extent. The difficulty of the operation reduces the selectivity of the second-stage operation; (2) The operation process is complicated, and there is a possibility of complications such as dilator rupture, postoperative bleeding, and expansion flap infection; (3) Increases the patient's Suffering and financial burden, taking up precious medical resources

[0004] 2. Ischemia delay technique

The main disadvantages are: it has not yet entered the stage of clinical application, and the drug has side effects, which have an impact on the patient's body
