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] Such as figure 1 , figure 2 and Figure 6 As shown, a minimally invasive pulmonary obstructor 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, 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 inside 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, the rotating me...

Embodiment 2

[0058] Such as Figure 2-Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that an LED supplementary light 405 is fixedly installed on the end surface of the second rotating block 403 away from the third threaded rod 407, and the LED supplementary light 405 is set no lower than two indivual.

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

Embodiment 3

[0061] Such as figure 2 and Figure 7 As shown, the difference between this embodiment and Embodiment 2 is that a control box 104 is fixedly installed on the outer wall of the cylindrical casing 101, and a controller 1042 is fixedly installed inside the control box 104, and the signal output terminals of the controller 1042 are respectively connected to 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 are electrically connected.

[0062] By adopting the above technical solution, it is convenient to control the device through the controller 1042 and simplify the operation of the device by the user.

Abstract

The invention discloses a lung blocking device for cardiothoracic surgery minimally invasive surgery, which comprises a lifting mechanism, a rotating mechanism, a fixing mechanism, a fine adjustment mechanism and an expansion mechanism, and the lifting mechanism comprises a cylindrical sleeve and a cylindrical insertion rod. When a cardiothoracic surgery minimally invasive surgery is carried out, lung tissue can be separated, pericardium is exposed, then an operator can carry out the surgery conveniently, the device can be firmly fixed to an operating table conveniently through the fixing mechanism, an operation assistant does not need to hold the dilator all the time, on one hand, the physical strength of the operation assistant is relieved, the shaking phenomenon is effectively avoided, the operation risk is reduced, a lifting mechanism and a rotating mechanism are matched with a fine adjustment mechanism, the device is suitable for minimally invasive operation environments of various angles, the applicability of the device is improved, the device has the light supplementing function, when the illumination of the operation environment is low, the brightness is improved by turning on an LED light supplementing lamp, and an operator can conduct an operation conveniently.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lung blocker for minimally invasive cardiothoracic surgery. Background technique [0002] With the advancement of science and technology, in recent years, surgical operations have gradually shifted from traditional open surgery with large trauma to minimally invasive surgery with small trauma. Small incision and laparoscopic surgery have gradually become the development trend of surgery. According to statistics, about 80 -More than 90% of thoracic surgery diseases can be treated with minimally invasive surgery. [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...
