Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1-3, an orthopedic fixation clamp includes two handles 1, two handles 1 are provided, a support block 2 extending downward is fixedly connected to a bottom surface of the left handle 1, rubber blocks 3 are fixedly connected to inner sides of the two handles 1, a chute 4 is provided above the left handle 1, a control rod 5 extending outward is clamped to a bottom end of the chute 4, a tip end of the control rod 5 is fixedly connected to an outer wall of a clamping device 6, a rack 7 is engaged to a top end of the clamping device 6, clamping rods 8 extending upward are fixedly connected to top ends of the handles 1 at two sides, clamping blocks 9 are fixedly connected to top ends of the clamping rods 8, two sides of a bottom end of each clamping rod 8 are fixedly connected to left and right ends of a spring 10, when the control rod 5 is pushed downward, a tooth block 64 loses an engagement force with the rack 7, and under an elastic force of the spring 10, fixed pincers can open rapidly to convenient to use, the below joint of clamping bar 8 has swivel 11, and swivel 11 not only can carry out mutual joint to two clamping bar 8 and fix, still the device can realize the main component support of centre gripping.

Clamping device 6 is including cuboid 61, the bottom surface fixed connection of cuboid 61 inner chamber is in the bottom of second spring 62, the top fixed connection of second spring 62 is in the middle part of slide 63 bottom surface, the side of slide 63 and the top fixed connection of control lever 5, the spout has been seted up respectively to the both sides of cuboid 61 inner chamber, and the side joint of slide 63 is in the spout, and the top surface fixed connection of slide 63 has the upwards tooth piece 64 that stretches out. Through the design of seting up the spout respectively in the both sides of cuboid 61 inner chamber for slide 63 can slide from top to bottom along the spout, and the elasticity of spring two 62 can make tooth piece 64 have the effort of activity that makes progress all the time, when tooth piece 64 and rack 7 intermeshing or separation, can reach the effect fixed with lax to the stationary dog, because slide 63 is with the most advanced interconnect of control lever 5, when control lever 5 activity, can control the interrelationship between tooth piece 64 and the rack 7.

The middle part of the rack 7 is movably sleeved in the inner cavity of the left grip 1, the rack 7 is arc-shaped, the bending angle value of the rack 7 is equal to the moving angle value of the grip 1, and the right end of the rack 7 is fixedly connected with the side surface of the right grip 1. Because the bending angle value of the rack 7 is equal to the rotating angle value of the handle 1, the clamping device 6 and the rack 7 can be stably clamped, and the rack 7 and the two handles 1 are movably sleeved and fixedly connected respectively, so that the integral control effect of the fixed clamp can be achieved by controlling the two handles 1.

The clamping block 9 is composed of two semi-rings, and the diameter values of the two semi-rings are equal. Through adopting the clamp splice 9 for the design of two equal hemizonids of diameter value for can close completely between two clamp splice 9, thereby ensure the fixed effect of centre gripping.

The number of clamping bars 8 has two, and the below intercrossing of two clamping bars 8, and swivel 11 installs in the intersection of two clamping bars 8, and the length value of swivel 11 top clamping bar 8 is greater than swivel 11 below clamping bar 8's length value. The principle of clamping bar 8 and clamp splice 9 activity and the principle of scissors are similar each other in the fixed pincers, and when applying the effort to two grips 1, the clamping bar 8 and the clamp splice 9 of top can realize the centre gripping effect simultaneously under the effort of swivel 11, through the design that is greater than the below length value with 8 top length values of clamping bar for top clamping bar 8 and clamp splice 9 can be convenient for stretch out to the inner chamber of patient's health, thereby be convenient for going on of orthopaedic surgery operation.

In summary, before use, the grip 1 on both sides is held by hand, at this time, the clamping rod 8 and the clamping block 9 are in an open state, when the bone needs to be clamped and fixed, the clamping block 9 is placed on both sides of the bone, then the grip 1 is clamped by applying pressure, in the process of applying pressure to the grip 1, the rack 7 and the toothed block 64 are meshed with each other, so that the clamping state of the fixing clamp can be maintained all the time, after clamping is finished, the control rod 5 is pulled downwards by pointing to the hand, at this time, the toothed block 64 retracts to the inner cavity of the rectangular body 61, the rack 7 and the toothed block 64 lose the force of mutual meshing, and under the elastic force of the first spring 10, the clamping rod 8 and the clamping block 9 are rapidly opened, so that the clamping and fixing work of the fixing clamp is finished.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not necessarily depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
