Description
Technical field
The present invention relates to orthopaedics technical field of medical instruments, specifically a kind of orthopaedics with anesthesia function
Use dilator.
Background technology
In bone surgery, medical worker is then drag hook to be fixed, so come wound pulled apart with drag hook in conventional method
Operate pretty troublesome, drag hook not only brings pain to patient but also is unfavorable for the adjustment of wound, some certain existing dilators
The trouble of drag hook fixation is also eliminated, but is unfavorable for the fixation of muscle, ligament tissue, the muscle of wound perimeter in operation,
Ligament tissue can gradually cover surgical field of view.Meanwhile wound circumference position can not be anaesthetized in surgical procedure, therefore in hand
Stimulation during art to patient is very big, so as to add the pain of patient.Therefore need to provide it is a kind of without fixed drag hook and
Be advantageous to fix the orthopaedics device for spreading of muscle, ligament tissue again.
The content of the invention
The technical problem to be solved in the present invention is for problem present in background technology, there is provided a kind of simple in construction, behaviour
Make easy to use, can not only improve treatment visual field when medical worker carries out bone surgery, moreover it is possible to reduce stimulation to patient and make
With specifically a kind of orthopaedics dilator with anesthesia function.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of orthopaedics with anesthesia function is used
Dilator, include operation handle, with externally threaded screw mandrel, crossbearer, swivel nut, connecting rod and two strutting with cavity structure
Hook, the operation handle are fixedly connected with screw mandrel top, and the screw mandrel other end is spirally connected through crossbearer center with swivel nut, by rotating
Stating operation handle drives the swivel nut to be rotated in screw mandrel, realizes that the swivel nut is moved up and down in screw mandrel and fixed, the support
The upper end for driving hook is flexibly connected with crossbearer, the both ends of the connecting rod respectively with swivel nut and strutting the middle part of hook and being flexibly connected,
The lateral surface for strutting hook is provided with several pores communicated with its cavity, is set in the crown center position for strutting hook
There are circular ozzle, the circular ozzle and the intracavity inter-connection for strutting hook.
Further, the described orthopaedics dilator with anesthesia function, wherein the lateral surface for strutting hook is set to
In the convex structure of outwardly convex, the pore is distributed in the convex structure in outwardly convex.
Further, the described orthopaedics dilator with anesthesia function, wherein the operation handle and screw mandrel are one
Body structure, is welded using stainless steel material, and interlaced anti-skidding annular knurl is provided with the operation handle.
Further, the described orthopaedics dilator with anesthesia function, wherein a diameter of the 0.1 of the pore~
0.3 millimeter.
Using a kind of orthopaedics dilator with anesthesia function of the present invention, compared with prior art, its is beneficial
Effect is：By rotating operating handle, band movable snail sleeve rotates in screw mandrel, is realized by connecting rod and the stretching for strutting hook is received
Contracting can also pass through the external anesthetic of circular ozzle being provided with fixed, can be by set in fixation procedure
Some pores implement local anaesthesia effect to strutting position, therefore patient is stimulated and substantially reduced, so as to mitigate the pain of patient.
With the features such as simple in construction, easy to use.
Brief description of the drawings
The present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Shown in figure：1- operation handles, 2- screw mandrels, 3- crossbearers, 4- strut hook, 5- swivel nuts, 6- connecting rods, 7- pores,
8- annular shapes ozzle, the anti-skidding annular knurls of 9-.
Embodiment
As shown in figure 1, it is of the present invention it is a kind of have anesthesia function orthopaedics dilator, include operation handle 1,
With externally threaded screw mandrel 2, crossbearer 3, swivel nut 5, connecting rod 6 and two strut hook 4 with cavity structure, the operation handle 1 with
The top of screw mandrel 2 is fixedly connected, and the other end of screw mandrel 2 is spirally connected through the center of crossbearer 2 with swivel nut 5, by rotating the band of operation handle 1
Move the swivel nut 5 to rotate in screw mandrel 2, realize that the swivel nut 5 is moved up and down and fixed in screw mandrel 2, it is described to strut the upper of hook 4
End is flexibly connected with crossbearer 2, and the both ends of the connecting rod 6 are respectively with swivel nut 5 and strutting the middle part of hook 4 and being flexibly connected, described
The lateral surface for strutting hook 4 is provided with several pores 7 communicated with its cavity, is set in the crown center position for strutting hook 4
There are circular ozzle 8, the circular ozzle 8 and the intracavity inter-connection for strutting hook 4.
Further, the described orthopaedics dilator with anesthesia function, wherein the lateral surface for strutting hook 4 is set to
In the convex structure of outwardly convex, the pore 7 is distributed in the convex structure in outwardly convex.
Further, the described orthopaedics dilator with anesthesia function, wherein the operation handle 1 and screw mandrel 4 are
