Pressure sore prevention pad for semi-extended straight infrapatellar approach tibia intramedullary nail surgery

Abstract

The invention relates to the technical field of medical equipment, in particular to a pressure sore prevention pad for a semi-extended straight infrapatellar approach tibia intramedullary nail surgery, which comprises a pressure sore prevention pad body, the pressure sore prevention pad body is divided into four layers, the uppermost layer of the pressure sore prevention pad body is a backing layer, a hydrophilic fiber layer is arranged below the backing layer, a non-woven fabric layer is arranged below the hydrophilic fiber layer, and the non-woven fabric layer is arranged below the non-woven fabric layer, a liner bottom layer is arranged on the lower side of the non-woven fabric layer, a front side line of the non-woven fabric layer is aligned with a front side line of the liner bottom layer, sewing positions are symmetrically arranged on the front side line of the non-woven fabric layer along the center line, and a gap is reserved between a rear side line of the non-woven fabric layer and a rear side line of the liner bottom layer. Gaps are reserved between two side lines of the non-woven fabric layer and two side lines of the liner bottom layer, the backing layer is made of a polyurethane material, and the interior of the hydrophilic fiber layer is of a Kiss-Cut structure. According to the invention, blisters and infection in the peripheral area of the articular cavity surgical incision can be avoided, and the risk of iatrogenic skin bruise is reduced.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an anti-pressure sore pad used for tibial intramedullary nail surgery in a semi-extended position. Background technique [0002] Tibial fracture is the most common long bone fracture in the human body, with an incidence rate of 17 out of 10,000. Along with my country's economic development and the popularization of motor vehicles, this proportion is still increasing. Tibial fractures are mostly high-energy injuries, often accompanied by complications such as deep infection, nonunion, malunion, and osteofascial compartment syndrome. These complications bring long-term pain and even disability to patients and take up a lot of medical resources. Therefore, the research on the treatment of tibial fractures is very important to reduce the occurrence of corresponding complications, increase patient satisfaction and reduce the increasing medical expenses.

Problems solved by technology

[0003] The new semi-extended infra-patellar (SEIP) tibial intramedullary nailing technique is an improvement over the current tibial intramedullary nailing technique. The handle will compress the skin and soft tissue behind the entrance, and it may even cause skin necrosis and infection under a long operation time. It is necessary and important to solve this problem
