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

Embodiment 1

[0026] like figure 2As shown, an L-shaped thoracoscopic surgery revealer is mainly composed of a fixed block 1, a bracket 2, a locking screw 3, a revealing tube 4, a pull wire 5, pliers 6, a self-holding clamp 7 and a short tube 8. Wherein, the structure of the bracket 2 is various, and is not limited to a certain structure. In this embodiment, the bracket 2 includes a 7-shaped column 21 and an arc-shaped plate 23, wherein a nut 22 is fixed at the suspended end of the horizontal section of the 7-shaped column 21, and the axis line of the nut 22 is vertical. The arc top of the arc plate 23 faces upward, and the end of the arc plate 23 is fixed to the side of the fixing block 1 . Described arc-shaped plate 23 has a strip-shaped groove (not shown) that runs through up and down, and this strip-shaped groove is offered along the circumferential direction of arc-shaped plate, and a trapezoidal bolt 24 passes through this strip-shaped groove and connects with The nut 22 is threade...

Embodiment 2

[0031] refer to figure 2 , and combined with image 3 It can be seen that, in this embodiment, the bracket 2 includes a horizontal bar 2a and a vertical bar 2b, wherein an adjusting block 2c is fitted on each end of the horizontal bar 2a, and the adjusting block 2c is controlled by the first locking screw 2d. Locked on the horizontal bar 2a. In use, the positions of the two adjustment blocks 2c on the horizontal bar 2a can be adjusted. The number of the vertical rods 2b is two, and these two vertical rods 2b are respectively located at the two ends of the horizontal rod 2a, and are passed through the through holes on the adjustment block 2c at the corresponding end of the horizontal rod, and are controlled by the second The locking screw 2e is locked on the adjusting block 2c. And, the bottom of one of the vertical rods 2b is fixed to the top of the fixed block 1, and the bottom of the other vertical rod 2b is fixed on the operating table when in use. During use, the posi...

Embodiment 3

[0033] refer to figure 2 , and combined with Figure 4 It can be seen that in this embodiment, in this embodiment, the bracket 2 includes a first connecting rod 2g and a third connecting rod 2n, wherein one end of the first connecting rod 2g is fixed to the fixed block 1, the The other end of the first connecting rod 2g is inserted into the central hole of the positioning sleeve 2h, and is locked on the positioning sleeve 2h by a screw 2k. Moreover, the outer end of the screw 2k is provided with a handle, which is perpendicular to the screw 2k, and the function of the handle is to facilitate the user to hold and turn the screw. The positioning sleeve 2h is fixed on one end of the second connecting rod 2l, and the other end of the second connecting rod 2l is hinged to the third connecting rod 2n through a pin shaft 2m, and the third connecting rod 2n is fixed on the surgical on stage. The rest of the structure of this embodiment is completely the same as that of Embodiment ...

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...
