Abstract
The invention provides a bone retractor used for thoracic operation, which belongs to the technical field of medical appliances. The bone retractor structurally consists of a retracting plate, retracting arms and a ratchet strip plate, wherein the retracting arms are two and are movably connected on the ratchet strip plate, slide holes are arranged on the retracting arms, the retracting plate is glidingly connected in the slide holes and is fixedly through screws, the lower parts of the retracting arms are provided with ratchet strip plate through holes, pawls are fixed on the lower ends of the retracting arms through springs, and ratchet strips matched with the pawls are arranged on the ratchet strip plate. Compared with the prior art, the invention has the characteristics of simple structure, convenient use, ingenious design and the like, the thoracic bones can be perfectly pulled, the operative field of the operation can be fully exposed, and the smooth proceeding of the operation is ensured.
Description
Technical field
The present invention relates to a kind of technical field of medical instruments, specifically a kind of bone retractor used for thoracic operation.
Background technology
In clinical thoracic surgery, usually need opening between the rib again, and rib is strutted at present,, finish operation so that enter into the thoracic cavity by narrow intercostal space with corresponding retractor.The drawing arm position of prior art retractor generally all is changeless, thoracic wall muscle can not get good tractive, and obstructs the view, and hinders operation to carry out, and the not parallel of retractor drawing arm often appear when using retractor easily, cause rib damage, and it is limited to retract area, is difficult for making breastbone to turn up, make that the effect that retracts is not ideal enough, a lot of organs can not well be exposed in doctor's the surgical field of view, and then damage the tissue of fracture, cause unnecessary damage.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art, a kind of bone retractor used for thoracic operation easy to use is provided.
The objective of the invention is to realize in the following manner, this a kind of bone retractor used for thoracic operation, its structure comprises and retracts plate, drawing arm, ratchet batten, drawing arm is provided with two and active being connected on the ratchet batten, drawing arm is provided with slide opening, retracts plate and is slidingly connected in the slide opening and is fixed by screw, and described drawing arm bottom has the rack-plate perforation, lower end at drawing arm is provided with ratchet by spring, and the ratchet batten is provided with the sour jujube bar that matches with ratchet.
Fixedly 1-5 is individual on each drawing arm retracts plate, and its optimal number is to fix 2 to retract plate.
The described arc of plate that retract for outwards bending.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of bone retractor used for thoracic operation of the present invention has simple in structure, characteristics such as easy to use, be movably connected on the rack-plate by ratchet structure in the drawing arm bottom, position that so just can the easy adjustment drawing arm, guarantee that the intercostal space between the rib obtains at utmost tractive, fully expose operation art open country, help operation to carry out, on drawing arm, be fixed with simultaneously a plurality of plates that retract, retract enlarged areas, tractive is satisfactory for result, and retract plate and be outside bending arc, so just avoided reducing the probability that rib sustains damage to the damage of rib with to the destruction of muscular tissue.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is a connection diagram in the rack-plate perforation of the present invention.
Labelling in the accompanying drawing is represented respectively:
1, retracts plate, 2, screw, 3, slide opening, 4, drawing arm, 5, the ratchet batten, 6, the sour jujube bar, 7, ratchet, 8, spring, 9, the rack-plate perforation.
The specific embodiment
Below in conjunction with Figure of description to explaining below the work of the present invention.
Shown in accompanying drawing 1, accompanying drawing 2, a kind of bone retractor used for thoracic operation of the present invention, its structure is formed by retracting plate 1, drawing arm 4, ratchet batten 5, drawing arm 4 is provided with two and active being connected on the ratchet batten 5, drawing arm 4 is provided with slide opening 3, retract that plate 1 is slidingly connected in the slide opening 3 and fixing by screw 2, described drawing arm 4 bottoms have rack-plate perforation 9, lower end at drawing arm 4 is fixed with ratchet 7 by spring 8, and ratchet batten 5 is provided with the sour jujube bar 6 that matches with ratchet 7.Fixedly 1-5 is individual on each drawing arm 4 retracts plate 1, as shown in Figure 1, is fixed with 2 and retracts plate 1 on each drawing arm 4.The described arc of plate 1 that retract for outwards bending.
When use is of the present invention, only need to determine the required fixed quantity that retracts plate according to actual needs, then the present invention is placed between the intercostal space, adjust the distance of two drawing arms then and can realize the tractive skeleton with ratchet is fixing, fully expose operation art open country, the assurance operation is carried out smoothly.
