Pressure sore prevention pad for semi-extension infrapatellar approach tibial intramedullary nail surgery

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a pressure sore prevention pad for semi-stretching patella lower approach tibial intramedullary nail surgery.

Background

Tibia fracture is the most common long bone fracture of human body, and the incidence rate is seventeen ten thousandths. This proportion is increasing with the economic development of our country and the popularity of motor vehicles. Tibial fractures are often high-energy injuries, often accompanied by complications such as deep infection, nonunion, deformity healing, periosteal syndrome and the like. These complications cause long-term pain and even disability to the patient and occupy significant medical resources. Therefore, through research on the treatment mode of the tibial fracture, the treatment mode is very important for reducing the occurrence of corresponding complications, increasing the satisfaction degree of patients and reducing the increasing medical expenses.

The new semi-extended infrapatellar-patello (SEIP) tibial intramedullary nail technique is an improvement on the current tibial intramedullary nail operation technique, but when the SEIP technique is applied to nail insertion, the intramedullary nail and the handle thereof can press the skin and soft tissues at the rear of the entrance, and even skin necrosis and infection can be caused under a longer operation time, which has the necessity and importance of solution.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a prevent pressing sore pad that is used for half stretching straight position kneecap to go into way shin bone intramedullary nail operation, including preventing pressing sore pad 1, prevent pressing sore pad 1 and divide into the quadruple, prevent pressing sore pad 1 the superiors and be back sheet 11, back sheet 11 below is equipped with hydrophilic fibrous layer 12, hydrophilic fibrous layer 12 below is equipped with non-woven fabrics layer 14, non-woven fabrics layer 14 downside is equipped with

liner bottom

13, 14 front side sidelines of non-woven fabrics layer and liner bottom 13 front side line pair its, 14 front side sidelines of non-woven fabrics layer department is equipped with suture 15 along the central line symmetry, leave the interval between 14 rear side sidelines of non-woven fabrics layer and the 13 back side line of liner bottom, all leave the interval between 14 both sides sidelines of non-woven fabrics layer and the 13 both sides sidelines of liner bottom.

The nonwoven layer 14 is the same size as the hydrophilic fibrous layer 12 for separating the dressing from the adhesive layer.

The back lining layer 11 is made of polyurethane, and the polyurethane back lining layer 11 has the functions of water resistance and bacteria resistance, and is very suitable for tibial intramedullary nail surgery of a semi-stretching infrapatella approach; the inside of the hydrophilic fiber layer 12 is a Kiss-Cut structure which supports high compliance and stretchability; the hydrophilic fiber layer 12 is made of acrylic fibers, the hydrophilic fiber layer 12 made of the acrylic fibers has strong and rapid liquid absorption capacity and excellent liquid storage capacity, can absorb liquid more than 25 times of the weight of the hydrophilic fiber layer, is superior to foam dressing in treating bloody exudates, and is convenient to treat bloody and oozing exudates in an operation.

Adhesive pieces are arranged in the space between the rear side and the left side and the space between the non-woven fabric layer 14 and the cushion bottom layer 13, and the adhesive pieces are soft silicone and can be firmly adhered in a bleeding environment.

Further, referring to fig. 2, the adhesive agent is provided in the space between the rear side and the left and right sides of the nonwoven fabric layer 14 and the backing sheet 13, but the front side is not provided, and the nonwoven fabric layer 14 and the backing sheet 13 are aligned on the front side; the prior art dressing products are basically provided with thin adhesive layers on four sides, but in actual operation, the end close to the wound needs to be folded back and is not used, so that the thin adhesive layer is prevented from being brought into the wound during nail insertion. Because the inserted nails are more useless and have larger friction, the sewing part 15 is also designed to sew the pressure sore prevention pad 1 on the skin.

The overall shape of the pressure sore prevention pad 1 is rectangular, the length of the pressure sore prevention pad 1 is larger than 8cm, the width of the pressure sore prevention pad 1 is larger than 5cm, the pressure sore area is not small in the operation, and the pressure sore prevention area needing to be protected is the area range of the non-woven fabric layer 14.

Specifically, referring to fig. 3, the pressure sore prevention pad 1 is placed on the upper portion of the nail wound to prevent the nail from pressing soft tissues such as skin around the knee. As shown in fig. 4, the operation procedure using the pressure sore prevention pad 1 is as follows:

1. the patient lies on an operating table which can transmit X-rays, a soft pad is padded below the popliteal fossa, the knee is bent by 30 degrees, and the adopted tibial intramedullary nail has 15-degree proximal bending;

2. the patellar ligament and infrapatellar fat pad were pulled medially after 4-5cm dissection from the lateral edge of the patellar ligament to expose the tibial ramp. Then the slope is opened by a pair of mosquito vascular clamps or a conical mouth gag. The nail feeding point is then determined by fluoroscopy to be located on the medial edge of the medial intercondylar crest of the tibia on the standard X-ray positive position plate and 5-10mm far from the anterior edge of the tibial plateau on the lateral position plate. Then establishing a tibial intramedullary nail feeding point by using the mouth gag;

3. the following operations are the same as the operations of fracture reduction, insertion of a guide needle, marrow enlargement, nail insertion and locking of interlocking nails at the far and near ends of the conventional high-flexion infrapatellar approach.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
