L-shaped video assisted thoracoscopic surgery showing device

Abstract

The invention discloses an L-shaped video assisted thoracoscopic surgery showing device. A fixed block is fixedly arranged on a support. The fixed block is vertically provided with two vertically-through via holes. Each via hole is communicated with a horizontally-formed screw hole. A locking screw is arranged in each screw hole in a penetrating mode. Two showing pipes are of an L-shaped structure. The vertical sections of the two showing pipes are inserted into the corresponding via holes in the fixed block respectively and fastened through the corresponding locking screws. A bracing wire is arranged in each showing pipe in a penetrating mode. The tail end of each bracing wire is exposed out of the vertical section of the corresponding showing pipe. A pair of forceps clamps the exposed end of each bracing wire. The head end of each bracing wire is exposed out of the horizontal section of the corresponding showing pipe. A pair of self-holding type clamping forceps is fixedly arranged at the exposed end of each bracing wire. The L-shaped video assisted thoracoscopic surgery showing device can conveniently, effectively and clearly show the surgery field of a video assisted thoracoscopic surgery. The showing device is small in size, and therefore only a small area of space needs to be occupied, interference between instruments is effectively avoided in the single-incision or double-incision video assisted thoracoscopic surgery, and the surgery can be smoothly performed.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an L-shaped thoracoscopic surgery revealer. Background technique [0002] In order to ensure the smooth progress of surgery, it is necessary to reveal a clear surgical field. In traditional open surgery, the operator uses his hands or other surgical instruments to pull the chest cavity. Although this can fully meet the needs of the operation, the trauma is relatively large, which is not conducive to the later recovery of the patient. In recent years, the development of minimally invasive surgery has made laparoscopic surgery popular. However, compared with traditional surgery, it requires higher exposure of the surgical field because it cannot be operated directly with hands. Taking thoracoscopic surgery as an example, usually thoracoscopic surgery is performed by making three incisions Q arranged in a triangle on the chest wall (such as figure 1 As shown), the lowermost inci...

Problems solved by technology

[0003] Under the current conditions of surgical exposure instruments, when performing thoracoscopic surgery with two incisions, a thoracoscope is placed in the lower incision, and a total of 3-4 instruments and surgical instruments are needed to expose the surgical field. Enter the thoracic cavity from the upper small incision (1-1.5cm in width and 3-5cm in length) and point to the same narrow surgical area. At this time, it is difficult to expose the surgical field, and the instruments will interfere with each other, thus increasing the risk of injury. Surgery Time and Risks

In single-incision thoracoscopic surgery, the thoracoscope and all instruments must enter the thoracic cavity through the only small incision (1.5 cm wide and 4-6 cm long) and point to the same surgical area. In this case, the surgical hand field is exposed The problem of difficulty and mutual interference between instruments is even more obvious. At this time, the operation efficiency is very low, and the operation risk is high, which affects the popularization and application of this single incision operation. Therefore, it is urgent to solve the above technical problems
