Description

Technical Field

[0001] The utility model relates to the technical field of surgical auxiliary equipment, in particular to a surgical incision retraction device. Background Art

[0002] Under the background of new military reform, the operational concepts and methods of modern warfare have undergone major changes, and the concepts, theories, technologies and organizational models of combat trauma treatment have also undergone profound changes. Modern warfare has many types of high-tech weapons, strong destructive performance, and complex injury factors, which bring great difficulties to combat wound treatment. Minimizing the death rate, disability rate and improving the functional recovery rate puts higher demands on our military field surgery, especially field surgical equipment.

[0003] In addition to maintaining basic vital signs, the most critical part of surgical treatment is to quickly expose the wound or incision during treatment, reach the affected area directly, and perform effective hemostasis, debridement, suturing and other processes. This requires a better incision retraction system to quickly expose the surgical field and enable the surgeon to quickly and clearly understand the patient's physical condition and perform operations. This requires a surgical retractor or surgical retractor to expose the surgical field. The current traditional surgical retractor system (also called a surgical retractor) is used to retract tissues, reveal the surgical scope, and facilitate exploration and operation. The shape, size and specifications vary significantly. Combined with the development status of related medical products at home and abroad, as well as the treatment needs in field surgery, we investigated and summarized the characteristics of existing field surgical retraction systems, as well as other surgical medical needs in field surgery. We believe that there are problems with the surgical retraction system being heavy, primitive and single in function. Specifically, there are the following shortcomings:

[0004] ①Previous surgical retractors were generally metal instruments, including chrome-plated, stainless steel, copper-nickel alloy or aluminum devices. Some surgical retractor systems are heavy and bulky. For example, large surgical retractor systems, including the main support arm, weigh more than 20 kilograms, which are inconvenient to carry.

[0005] ② To ensure adequate exposure of the surgical field, this type of surgery often requires a second or third assistant to manually use a surgical hook plate for continuous traction, which is time-consuming and labor-intensive. During wartime, shortages of medical resources, especially medical personnel, are common, so there is an urgent need to reduce the workload of medical personnel.

[0006] ③ Traditional hook plates are mostly metal hook plates and are separate individual pieces. Due to different surgical locations, such as cranial, thoracic, abdominal, spinal or limb trauma and the inconsistency of incision type, size, depth, etc., multiple injuries require various special surgical retractors, which also increases the burden of logistics support.

[0007] ④ Under field conditions, the equipment cannot be disinfected in time and may not be able to meet the surgical needs of a large number of wounded soldiers.

[0008] Therefore, it is necessary to study and provide a surgical device that can solve the above-mentioned various problems. Utility Model Content

[0009] The technical problem to be solved by the utility model is to provide a surgical incision retraction device, which utilizes an adjustable annular arm structure combined with a retraction hook plate combination, has a more stable fixation, can adapt to different incision types, has a good retraction effect, and is not easy to deform.

[0010] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0012] Furthermore, the main support member includes a support column, a support rod is installed on the support column, an adjustable lock is provided between one end of the support rod and the support column, and the mounting seat on the annular arm is detachably mounted on the other end of the support rod.

[0013] Furthermore, the lock buckle comprises a lock seat, and through holes are respectively opened on the lock seat corresponding to the support column and the support rod, and a locking screw is rotatably connected to the hole wall of the through hole.

[0014] Furthermore, the annular arm also includes a flexible shell sleeved on the outside of the cross bar unit and the movable joint, and an LED shadowless lamp is arranged on the flexible shell.

[0015] Furthermore, the retracting hook plate is made of injection-molded polycarbonate material with strong light-conducting property, an LED light source is provided at the connection between the support handle and the retracting hook plate, and a power supply battery is also provided inside the support handle.

[0016] Furthermore, the fixer comprises a fixing seat, and the fixing seat is provided with clamping holes corresponding to the cross bar unit and the supporting handle respectively, and the clamping holes are provided with locking nuts correspondingly.

[0017] Furthermore, a formable hose is connected and installed on the main body support, and a remote monitoring camera is provided on the hose.

[0018] Beneficial effects of the utility model:

[0019] In actual use scenarios, when performing surgery in the field, the main support is fixed on the operating table according to the position of the patient requiring surgery. The main support is between 40 and 60 cm long, retractable and adjustable in length. Then the ring arm is installed at the appropriate position on the main support, and the appropriate type of retractor hook plate is fixed to the appropriate position on the appropriate crossbar unit on the ring arm using a fixator.

By connecting multiple retractor hook plates in series and fixing them side by side, the force-bearing area is increased, the pulling strength is guaranteed, and the purpose of one hook for multiple uses is achieved.
