Embodiment 1

[0048] like Figure 1 - Figure 7 As shown, a thoracoscopic rib bone tumor resection is used by the support, including a bottom regulating mechanism 1 for adjusting the back support, a hook body adjustment mechanism 3 for adjusting the slit, a hook body 4, and a hook body for adjusting the hook body. The outer support mechanism 2 of the adjustment mechanism 3, the bottom adjustment mechanism 1 is attached to the outer support mechanism 2, and the outer support mechanism 2 is connected to the top of the hook body adjusting mechanism 3, and the hook body 4 is mounted on the hook body 4, outside The support mechanism 2 is connected to the bottom adjustment mechanism 1 by a locking mechanism 5;

[0049] The bottom regulating mechanism 1 includes a bottom plate 11, an airbag 12, a restricted groove 13, and the upper end of the bottom plate 11 is mounted, and the lower end of the adjustment airbag 12 is mounted to connect the outer gas source, and the finisher groove 13 is provided on bot...

Embodiment 2

[0055] like Figure 8 The difference between this embodiment and the first embodiment is:

[0056] The locking mechanism 5 includes a second button 511, the expansion lever 512, the second pressing cone block 513, the second locking lever 514, and the second button 511 are connected to the connecting rod 21, and the second button 511 is connected to the expansion rod. 512, the expansion lever 512 is provided with a second pressure-press cone block 513, and the second pressure relief block 513 is provided with the second locking lever 514, the second locking lever 514 and the connecting rod 21 are provided with a second. The reset spring 515, the bottom plate 11, and the second locking lever 514 are provided with a locking slot, and when the position of the independent hook body 4 is required, press the second button 511 so that the second locking lever 514 is retracted. Thus, the position of the outer support mechanism 2 is released, and the second reset spring 515 can cause the se...

Abstract

The invention discloses a distraction device for thoracoscope rib bone tumor resection. The distraction device comprises a bottom adjusting mechanism for adjusting a back support, a hook body adjusting mechanism for adjusting an incision, a hook body mechanism and outer supporting mechanisms for adjusting the position of the hook body adjusting mechanism, the outer supporting mechanisms are mounted on two sides of the bottom adjusting mechanism, the hook body adjusting mechanism is connected to the top end of the outer supporting mechanisms, the hook body mechanism is installed on the hook body adjusting mechanism, and the outer supporting mechanisms are connected with the bottom adjusting mechanism through a locking mechanism. Through cooperation of the hook body adjusting mechanism and the hook body mechanism, the opening direction and the opening effect of the hook body mechanism are adjusted, the outer supporting mechanisms can adjust the position in the limiting groove and can also be disassembled and additionally installed, and therefore the number of the hook body mechanism is increased, expansibility is improved, the back is supported through the bottom adjusting mechanism, therefore, patients in different postures can be reversely supported and adjusted, incision expansion is facilitated, the thoracic cavity is expanded more easily, and a good view is guaranteed.

Description

Technical field [0001] The present invention relates to the field of thoracic therapeutic, and more particularly to a thoracic mirror rib bone tumor rendering support. Background technique [0002] Rib tumors are common diseases for thoracic surgery. In order to achieve thorough radical purposes, the normal rib bone tissue in the range of 5 cm of the rib tumor and its two ends is required. Therefore, this generally used rib tumor-centered long chest slit, usually about 10 cm or even longer, After seriously affecting the appearance of the incision. With the development of thoracoscopic surgery, some people attempted abroad in recent years to use thoracoscopic tumor resection and achieve good results. Usually the thoracoscopic rib bone tumor resection is a slider pull on a metal shot. [0003] The current elimination is human as a manual expansion and grip, thereby expanding its fixability, and some of the existing expansion devices are not easy to adjust, and for some obese body, ...
