Example 1

Referring to fig. 1-4, the present embodiment provides an orthopedic steel wire retractor, which includes a guiding tube 1 and a guiding wire 2 sleeved in the guiding tube 1, one end of the guiding tube 1 is arc-shaped, a channel 3 extending along the length direction of the guiding tube 1 is disposed inside the guiding tube 1, the channel 3 penetrates through the guiding tube 1, the arc-shaped end of the guiding tube 1 is inserted into a wound and attached to a position to be bound when in use, so that one end of the channel 3 located at the arc-shaped position is a blunt opening to prevent tissue from being scratched by edges and corners during use, the guiding wire 2 freely slides in the channel 3, the length of the guiding wire 2 is greater than that of the guiding tube 1, that is, the inner diameter of the channel 3 is greater than the outer diameter of the guiding wire 2, the guiding wire 2 can slide along the channel 3 and extend to the outer side of the channel 3, a barb 4 is disposed at the end of the guiding, barb 4 can the components of a whole that can function independently setting with guide wire 2, be connected through modes such as gluing or screw thread again, also can integrated into one piece increase barb 4 and guide wire 2's joint strength, guide wire 2 keeps away from 4 one end fixedly connected with of barb and presses cap 6, it is provided with a reset spring 5 to press between cap 6 and the guiding tube 1, this reset spring 5 one end with press cap 6 fixed connection, one end and guiding tube 1 fixed connection, when reset spring 5 is in the unstressed state, barb 4 is located guiding tube 1, press cap 6, when compressing reset spring 5, barb 4 stretches out outside guiding tube 1, so that with the most advanced curved hook of steel wire on the metal hook.

The working principle is as follows: when utilizing the steel wire to ligature the bone piece at fracture position, make reset spring 5 be in natural state, insert guiding tube 1 from wound department one side, the opposite side is worn out, then press and press cap 6, make guide wire 2 drive barb 4 along with passageway 3 slide until barb 4 extends to the guiding tube 1 outside, then the steel wire one end bending that will be used for the ligature colludes at the metal, loosen and press cap 6, reset spring 5 resets, it removes to drive guide wire 2, thereby make steel wire one end draw in passageway 3 together, finally, hold the tip of drag hook, return guiding tube 1 according to former way, stimulate the steel wire to the offside, can accomplish the winding of steel wire, the winding efficiency of steel wire has effectively been promoted, doctor's operation burden has been reduced.

In the operation process, in order to ensure that the insertion of the guide tube 1 is smoother, the barb 4 and the guide wire 2 are more tensile, and the materials of the guide tube 1, the barb 4 and the guide wire 2 are hard alloy materials, such as aluminum and 304 stainless steel, wherein the 304 stainless steel has no peculiar smell, does not have precipitation of harmful substances in the use process, is cleaner and more sanitary, and is more suitable for being used in binding.

Example 2

In the in-process of carrying out the ligature, because guide tube 1 need insert from wound one side to wear out from the opposite side, at this in-process, because guide tube 1 need extrude open peripheral muscle, the tissue of fracture position, and the passageway 3 of guide tube 1 is the opening setting again, alright can have some tissue to get into in the

passageway

3, and 3 internal diameters of passageway are less, be the arc again, the clearance is very troublesome, and if the clearance is not in place, nourish the bacterium easily in passageway 3, cause the influence to the patient health of next use. In contrast, this embodiment is optimized on the basis of embodiment 1, please refer to fig. 5-7, one end of the guiding tube 1, which is far from the pressing cap 6, is detachably connected with a stopper 7, the stopper 7 and the end of the guiding tube 1 contact one side to seal and block the port of the channel 3, i.e., the area of the end of the stopper 7 contacting the guiding tube 1 is larger than the cross-sectional area of the port of the channel 3, the tissue which is not damaged in the inserting process of the guiding tube 1 enters the channel 3, and when the stopper 7 is taken down and the steel wire is fixed on the barb 4 and pulled back, the moving direction is opposite to the opening direction of the end of the channel 3, so that the tissue cannot enter the channel 3, thereby effectively ensuring the cleanness and sanitation in the channel 3 and reducing the difficulty in cleaning the pulling hook after use.

Wherein as a concrete implementation mode of keeping off head 7, set up keeping off head 7 to conical part, its bottom surface and guide tube 1 contact, guiding tube 1 is kept away from to the most advanced, and set up spliced pole 8 at the bottom surface middle part of keeping off head 7, spliced pole 8 insert in the guide tube 1 and with guide tube 1 threaded connection, be provided with the internal thread in the guide tube 1 promptly, spliced pole 8 and guide tube 1 threaded connection, this moment, barb 4 is located the slightly inboard position of guide tube 1, when not pressing pressure cap 6, barb 4 can not lead to the fact the influence to the screw in of spliced pole 8, and can make the most advanced of keeping off head 7 be blunt head, and the side of keeping off head 7 is level and clean, when inserting the wound with guide tube 1, can effectively reduce the resistance, when avoiding fish tail fracture position tissue, promote the smooth and clean nature of inserting.

As another embodiment of the blocking head 7, the blocking head 7 comprises a blocking portion 10 and a connecting portion, the blocking portion 10 is configured to be conical, the area of the bottom surface of the blocking portion 10 is larger than the cross-sectional area of the port of the channel 3, preferably the same as the cross-sectional area of the guiding tube 1, so as to reduce the resistance when inserting into the wound, and the connecting portion is a hook 9 fixedly connected with the bottom surface of the blocking portion 10, and the hook 9 is matched with the barb 4. When using, press earlier and press cap 6, make barb 4 stretch out the guide tube 1 outside, then link up crotch 9 with barb 4 collude, loosen and press cap 6, barb 4 retracts into guide tube 1, it seals passageway 3 port to drive department of blocking 10, and what inserted in-process department of blocking 10 received is pressure all the time, make department of blocking 10 and passageway 3 port can remain sealed all the time, can not have the tissue to get into in the passageway 3, when connecting the steel wire, press and press cap 6, make barb 4 release the top 7, then take off the top 7 can, for a first implementation mode, this kind of implementation mode structure is simpler, and the operation is more convenient, the doctor of being more convenient for uses.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited thereto, the protection scope of the present invention is defined by the claims, and all structural changes equivalent to the contents of the description and drawings of the present invention should be included in the protection scope of the present invention.
