Problems solved by technology

[0003] In minimally invasive cardiothoracic surgery, the incision is often made from the underarm, but after entering the chest cavity, the lung tissue will affect the exposure of the surgical site, and it needs to be blocked by instruments for the next step. The existing lung blocker The function is single, and the surgical assistant needs to be supported all the time during the operation, which consumes a lot of physical strength of the surgical assistant, and as the physical strength is exhausted, the lung blocker may shake, which will have a huge impact on the safety of the operation. the threat of

Embodiment 1

[0044] like figure 1 , figure 2 and Image 6 As shown, a minimally invasive lung blocker for cardiothoracic surgery according to an embodiment of the present invention includes a lifting mechanism 1 , a rotating mechanism 2 , a fixing mechanism 3 , a fine-tuning mechanism 4 and an expansion mechanism 5 .

[0045] Among them, such as figure 1 and figure 2 As shown, the lifting mechanism 1 includes a cylindrical sleeve 101 and a cylindrical insertion rod 102, the lower end of the cylindrical insertion rod 102 is inserted into the interior of the cylindrical sleeve 101, and the outer wall of the upper end of the cylindrical sleeve 101 is fixed A first threaded rod 1031 for fixing the cylindrical insertion rod 102 is installed, and one end of the first threaded rod 1031 is fixedly connected with a first knob block 103;

[0046] Among them, such as Figure 1-Figure 2 as well as Figure 8 As shown, the rotating mechanism 2 includes an electric push rod 201, a first rotating ...

Embodiment 2

[0058] like Figure 2-Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the end face of the second rotating block 403 away from the third threaded rod 407 is fixedly installed with an LED fill light 405, and the LED fill light 405 is set not less than two indivual.

[0059] By adopting the above technical solution, when the illuminance of the operating environment is low, the brightness can be increased by turning on the LED fill light 405, which is convenient for the operator to operate without adding other lighting tools.

Embodiment 3

[0061] like figure 2 and Figure 7 As shown, the difference between this embodiment and Embodiment 2 is that the control box 104 is fixedly installed on the outer wall of the cylindrical sleeve 101, the controller 1042 is fixedly installed inside the control box 104, and the signal output ends of the controller 1042 are respectively It is electrically connected with the electric control end of the LED fill light 405 , the electric control end of the electric push rod 201 and the electric control end of the servo motor 501 .

[0062] By adopting the above technical solution, the control of the device by the controller 1042 is facilitated, and the operation of the device by the user is simplified.

Abstract

The invention discloses a lung blocker for minimally invasive cardiothoracic surgery, which includes a lifting mechanism, a rotating mechanism, a fixing mechanism, a fine-tuning mechanism and an expansion mechanism. The lifting mechanism includes a cylindrical sleeve and a cylindrical insertion rod. The present invention can isolate the lung tissue and expose the pericardium during minimally invasive cardiothoracic surgery, thereby facilitating the operation for the operator, and the device can be firmly fixed on the operating table through the fixing mechanism, and There is no need for the surgical assistant to hold the dilator all the time. On the one hand, it reduces the physical strength of the surgical assistant, and on the other hand, it effectively avoids the phenomenon of shaking and reduces the risk of surgery. Through the lifting mechanism, rotating mechanism and fine-tuning mechanism, it is suitable for minimally invasive surgical environments at various angles. , improve the applicability of the device, and have the function of supplementary light. When the illumination of the operating environment is low, the brightness can be increased by turning on the LED supplementary light, which is convenient for the operator to operate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lung-obstructing device for minimally invasive surgery in cardiothoracic surgery. Background technique [0002] With the advancement of science and technology, in recent years, surgical operations have gradually shifted from traditional, invasive open surgery to less invasive minimally invasive surgery. Small incision and laparoscopic surgery have gradually become the development trend of surgery. According to statistics, about 80 -More than 90% of thoracic surgical diseases can be treated with minimally invasive surgery. [0003] When performing minimally invasive cardiothoracic surgery, the incision is often made from the armpit, but after entering the chest cavity, the lung tissue will affect the exposure of the surgical site, and it needs to be blocked with instruments for the next step. The function is single, and the surgical assistant needs to be supported all t...
