Abstract
The utility model discloses a kind of skin closure exterior fixation bracket, comprise screw thread flat bar, be set in the pair of sliding lateral mass of described screw thread flat bar both sides, be threaded onto described screw thread flat bar two ends and with described slip lateral mass a pair nut, multiple Z-type spicule and be sheathed on described screw thread flat bar and two springs of the described slip lateral mass be connected respectively and described nut one to one, each described Z-type spicule syringe needle is relatively individually fixed in the opposite sides of two described slip lateral mass.This utility model can not cut skin or soft tissue in use, avoids secondary injury.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of skin closure exterior fixation bracket.
Background technology
Skin closure exterior fixation bracket is mainly used in the tractive prosthesis of skin, muscle and tendon soft tissue clinically, and the soft tissue larger for tractive defect or local skin carry out cover type to traction, finally reach the effect that skin covers.
At present, clinical conventional skin closure exterior fixation bracket formally can be divided into intrusive mood and non-intrusion type two kinds.The skin closure exterior fixation bracket of intrusive mood is mostly plastic material and makes, be not easy sterilization, and spicule is all very very thin, be easy to cause traction force that covering skin and soft tissue or pulling force cannot be pulled not excessive, thus cutting skin and soft tissue easily cause secondary injury.
Summary of the invention
The purpose of this utility model is to provide a kind of skin closure exterior fixation bracket, skin and soft tissue can be pulled in use to cover defect and can not cut skin and soft tissue again, avoid secondary injury.
The technical scheme realizing above-mentioned purpose is:
A kind of skin closure exterior fixation bracket, comprise screw thread flat bar, be set in the pair of sliding lateral mass of described screw thread flat bar both sides, be threaded onto described screw thread flat bar two ends and with described slip lateral mass a pair nut, multiple Z-type spicule and be sheathed on described screw thread flat bar and two springs of the described slip lateral mass be connected respectively and described nut one to one, wherein
Each described Z-type spicule syringe needle is relatively individually fixed in the opposite sides of two described slip lateral mass.
In above-mentioned skin closure exterior fixation bracket, the external diameter of described screw thread flat bar has screw thread, and its cross section is flat-shaped.
In above-mentioned skin closure exterior fixation bracket, the cross section of described Z-type spicule is flat-shaped.
In above-mentioned skin closure exterior fixation bracket, described slip lateral mass has the flat hole of the tail end grafting holding described Z-type spicule.
In above-mentioned skin closure exterior fixation bracket, described slip lateral mass bottom has the circular hole can inserting circular spicule.
In above-mentioned skin closure exterior fixation bracket, the outer ring of described nut is provided with annular knurl groove and blind hole.
In above-mentioned skin closure exterior fixation bracket, described slip lateral mass has the flat hole holding described screw thread flat bar and pass, and bottom is provided with circular hole.
The beneficial effects of the utility model are: slip lateral mass is enclosed within screw thread flat bar by this utility model, and driven by sheet nut to slidably reciprocate, solve traditional invasive skin closure exterior fixation bracket for this great problem easily cutting skin soft tissue in the traction process of skin soft tissue, and, this utility model structure is simple, cost is lower, easy to operate, greatly can raise the efficiency, reduce time and the hidden danger of operation.
Accompanying drawing explanation
Fig. 1 is the structure chart of skin closure exterior fixation bracket of the present utility model;
Fig. 2 is the structure chart of the slip lateral mass of the exterior fixation bracket of skin closure shown in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 and Fig. 2, skin closure exterior fixation bracket of the present utility model, comprise pair of sliding lateral mass 1, screw thread flat bar 2, two springs 3, a pair nut 4 and multiple Z-type spicule 5.
Two slip lateral mass 1 are set in the both sides of screw thread flat bar 2 respectively, that is: slip lateral mass 1 has the flat through hole 11 holding screw thread flat bar 2 and pass.Two sheet nuts 4 are screwed in the two ends of screw thread flat bar 2 respectively, with two slip lateral mass 1 one_to_one corresponding.Pass through the spring 3 be enclosed within screw thread flat bar 2 equally between often corresponding slip lateral mass 1 and sheet nut 4 to connect, play certain cushioning effect.
Slip lateral mass 1 has the flat hole 12 of the tail end grafting holding Z-type spicule 5.The tail end grafting of each Z-type spicule 5 is fixed on the opposite sides of two slip lateral mass 1, and the syringe needle of each Z-type spicule 5 is relative.And the cross section of Z-type spicule 5 is flat-shaped, to increase the contact area with skin, soft tissue, thus skin or soft tissue can not be cut.
Slip lateral mass 1 has the hole for subsequent use 13 of the tail end grafting holding circular spicule.
The outer ring of sheet nut 4 is provided with annular knurl groove 41, increases friction, and convenient being used for rotates.The outer ring of sheet nut 4 is also provided with blind hole 42, can insertion rod convenient and strength-saving ground rotating moving piece nut 4 be passed through.
To sum up, during use, the sheet nut 4 at turn two ends, Compress Spring 3 to promote slip lateral mass 1, thus drives Z-type spicule 5 move toward one another on both sides, utilizes spicule to pull the skin soft tissue at defect two ends.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
