Embodiment 1

[0038] A thoracoscopic surgery puller includes: expanding the outer cover 1, the expansion port 11 is opened;

[0039] Adjust the knob 2, the adjustment knob 2 is disposed above the expanded outer cover 1, and the bottom end of the adjustment knob 2 is fixedly connected to the adjustment screw 21;

[0040] Linked Tray 3, the outer surface of the linkage disk 3 is slidably coupled to the inner surface of the expanded outer cover 1, and the inner threaded hole 31 and a limit sliding hole 32 are respectively opened, and the linkage disc 3 The inner side fixed connection has a linkable plate 33, and the inner wall of the linkage plate 33 is fixedly connected to the drive shaft 34;

[0041] The connecting rod 4 is disposed on the outer surface of the transmission shaft 34 by the transmission hole 41, and the top end of the connecting rod 4 is fixedly connected to the sleeve 42, and the inner wall of the expanded outer cover 1 is fixed. Expand the slide axis 43;

[0042] The expanded co...

Embodiment 2

[0073] The inner surface of the expanded hood 5 is opened with a mosaic slot 51, and the outer surface cover of the expanded hood 5 is provided with a connecting cover 6, and the bottom end of the connecting cover 6 is fixedly coupled to the elastic contraction ring 61.

[0074] The inner side of the expansion cover 5 is convenient for the tightening of the elastic shrinking ring 61, and the outer sleeve 6 of the two sets of expanded hood 5, the connection cover 6 can be adapted according to the extension of the expanded hood 5. The stretching and contraction, ensuring the stability of the expansion of the dilated hood 5 stretched or contracted, avoiding frictional damage or extrusion of the surface of the shroute 5 when stretching or shrinking.

[0075] The connecting cover 6 is coupled to the surface of the inner surface of the inlay groove 51 by medical elastic rubber.

[0076] Medical elastic rubber is the elastic extension and contraction of the connecting cover 6 to provide ...

Embodiment 3

[0082] The bottom portion of the expanded outer cover 1 is fixedly coupled with a medical connection layer for expanding the outer cover 1 to be attached to the outer side of the patient's thoracoscopic surgery.

[0083] The medical connection layer includes an outer adhesive layer and an inner disinfectant sponge layer.

[0084] The medical connection layer facilitates the surface of the outer cover 1 to form a connection structure when contacting the patient's skin, ensuring stability when the expansion cover 1 is installed.

[0085] The viscose layer is convenient to expand the expansion of the outer cover 1 and the patient's skin;

[0086] The surface of the sterilization sponge layer is directly contradiated with the patient's skin, so that it is convenient for occlusion and disinfection outside the patient's window, avoiding the external debris to infection, enhance the stability and safety of patient surgery.

Abstract

The invention provides a thoracoscopic surgery retractor. The thoracoscopic surgery retractor comprises: an expansion outer cover, wherein an expansion opening is formed in the bottom of the expansion outer cover; an adjusting knob, wherein the adjusting knob is arranged above the expansion outer cover, and the bottom end of the adjusting knob is fixedly connected with an adjusting lead screw; and a linkage disc, wherein the outer surface of the linkage disc is slidably connected to the inner surface of the expansion outer cover, an inner threaded hole and a limiting sliding hole are formed in the linkage disc, a linkage plate is fixedly connected to the inner side of the linkage disc, and a transmission shaft is fixedly connected to the inner wall of the linkage plate. According to the thoracoscopic surgery retractor, the expansion cover plates are movably installed in the expansion outer cover, the dilation degree of the two expansion cover plates can be conveniently adjusted through the adjusting knob, and the expansion range of the expansion cover plates is limited by the expansion opening range; and the safety of incision expansion in the thoracoscopic surgery by the expansion cover plate is ensured.

Description

Technical field [0001] The present invention relates to the field of medical devices, in particular, to a thoracoscopic surgery puller. Background technique [0002] The thoracoscope is known as one of the major breakthroughs in the last century, which is a representative surgery of the chest minimally invasive surgery, and the thoracoscopic surgery uses modern TV camera technology and high-tech surgery equipment, in the chest wall sleeve or minute incision. The micro-eugenic new technologies of chest complex surgery were completed. It changed some of the treatment concept of chest surgery. It is considered to be the most significant progress in the end of the 20th century, which is the direction of future thoracic surgery. [0003] When the thoracoscopic surgery is usually carried out under 3-4 1.5cm chest wall small incision, the doctor is a special surgical instrument for television, which is equal to extending the doctor's eyes into the patient's chest to operate operation, T...
