Embodiment Construction

[0021] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0022] like Figure 1-3 As shown, the present invention provides a technical solution: a convenient thoracic surgery retractor device, comprising a retractor 1, the inner surface of the retractor 1 is provided with a cushion, the shape of the cushion matches the shape of the retractor 1, By arranging the soft pad, the rigid contact of the retractor 1 to the patient's affected part can be avoided, causing excessive behavior in the patient's affected part. The number of retractors 1 is five, and the right side of the retractor 1 is fixedly connected with the housing 2. Inside the housing 2 The first pin shaft 3 is fixedly connected, and the outer surface of the first pin shaft 3 is movably connected with two connecting rods 7. The connecting rod 7 is movably connected with the second pin shaft 5. A third pin shaft 6 is movably connected, the back of...

Abstract

The invention discloses a drag hook device with convenience in use for a thoracic surgery, belonging to the technical field of surgical auxiliary instruments. The drag hook device comprises five draghooks, wherein the right side surface of each drag hook is fixedly connected with a shell; a first pin shaft is fixedly connected with and arranged in each shell; two connecting rods are movably connected with the outer surface of each first pin shaft; the connecting rods are movably connected with second pin shafts; the middle positions of the opposite faces of every two connecting rods are movably connected through a same third pin shaft; a sliding groove is arranged in the back face of the inner wall of each shell; and a sliding block is slidably connected with and arranged in each slidinggroove. The drag hook device with convenience in use for the thoracic surgery has the following advantages: through mutual cooperation of a threaded cap, an external thread, a bearing, connecting plates, the connecting rods and the drag hooks, the expansion range and the shrinkage range of the drag hooks can be adjusted according to demands, so the drag hook device can adapt to affected parts cutby incisions with different sizes, and the applicability of the drag hook device can be improved.

Description

technical field [0001] The invention belongs to the technical field of surgical auxiliary instruments, and in particular relates to a pull hook device for thoracic surgery which is convenient to use. Background technique [0002] In surgery, it is often necessary to incise the skin and muscles, and then use retractors to pull the skin and muscles to both sides, thereby exposing the required surgical field of view so that doctors can perform normal operations on patients, but ordinary retractors cannot be used according to the patient's incision. The size is adjusted, so that it cannot be applied to patients with different sizes of incisions, so that the applicability is low. Therefore, a retractor device for thoracic surgery that is convenient to use and adjust is needed to solve the above problems. Contents of the invention [0003] (1) Solved technical problems [0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ...
