Abstract
The utility model relates to cylindrical distraction forceps, which comprise a left forceps handle, a right forceps handle, a sliding screw and a tensile sleeve, wherein two sides of the front end of the tensile sleeve are respectively connected with a left dilation rod and a right dilation rod; the ends of the left and right dilation rods are connected with mutually opposite dilation valves; tensile rods are connected between the tail end of the tensile sleeve and the left and right forceps handles through hinges; the tensile sleeve is provided with a chute opening; the tensile sleeve slides on the sliding screw through the chute opening; the lateral surface of the left forceps handle is provided with a through hole; the right forceps handle is provided with a threaded hole corresponding to the through hole; and a locking screw penetrates through the through hole and the threaded hole to fasten the left forceps handle and the right forceps handle. According to the cylindrical distraction forceps, the structural design can fulfill the aim of continuously and fully exposing surgical view, and surgery is carried out without injuring adjacent organ tissues; and by gradual distraction, full surgical view of a minimally invasive implanted inter-spinal fusion instrument can be achieved, so that operative wound is greatly reduced and postoperative complications are reduced.
Description
Technical field
This utility model relates to field of medical devices, and especially a kind of tubular struts pincers.
Background technology
At present domestic in anterior cervical operation; Mainly reach the purpose that exposes surgical field of view, possibly produce surgical field of view in the art and expose insufficiently, perhaps can not continue to expose fully through vertebral body dilator and manpower tractive; Even situation such as compressing esophagus etc., thereby cause the hidden danger in the operation.
Current both at home and abroad in Lumbar Fusion operation, adopt open surgery more, one comes operation wound big, and two come postoperative lower back muscle cicatrixization, and the postoperative lower back is unable, and complication such as rest pain are many.
The utility model content
The technical problem that this utility model will solve is: in order to overcome the above-mentioned middle problem that exists, provide a kind of tubular to strut pincers, its project organization is reasonable and easy to use.
This utility model solves the technical scheme that its technical problem adopted: a kind of tubular struts pincers; Comprise left side pincers handle, the right side pincers handle that is connected with left side pincers handle and sliding screw and the flexibility that is arranged on left and right pincers handle junction; The front end both sides of described flexibility are connected with left expanding bar and right expanding bar respectively; The end of left and right expanding bar is connected with involutory expansion lobe each other, and hinge is connected with stretch between the tail end of flexibility and the left and right pincers handle, offers the chute mouth on the described flexibility; Flexibility is slided on sliding screw through the chute mouth; Pincers handle side, a described left side offers through hole, offers and the corresponding screwed hole of through hole on the right pincers handle, and left side pincers handle passes through hole with right pincers handle through tie down screw and screwed hole is fastening fixing.
For can resilience fast after use, be connected with left shell fragment and right shell fragment respectively on the described left and right pincers handle medial surface.
In order when operating, to avoid slip phenomenon, described left and right pincers handle is provided with anti-skidding stricture of vagina on the lateral wall.
The beneficial effect of this utility model is, the tubular of this utility model struts pincers, and that this structural design can reach is lasting, fully expose the purpose of surgical field of view; Do not damage simultaneously and close on organ-tissue and undergo surgery; And combine pedicle nail system of Wicresoft, through strutting step by step, can reach the surgical field of view that sufficient Wicresoft implants Invasive lumbar fusion device; Reduce operation wound greatly, reduce post-operative complication.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is the front view of this utility model;
Fig. 2 is the side view of Fig. 1.
1. expansion lobes among the figure, 2. right expanding bar, 3. sliding screw, 4. right pincers handle, 5. tie down screw, 6. left side pincers handle, 7. stretch, 8. flexibility, 9. left shell fragment, 10. left expanding bar, 11. right shell fragments, 12 anti-skidding stricture of vaginas.
The specific embodiment
Combine accompanying drawing that this utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of this utility model only is described in a schematic way, so it only show the formation relevant with this utility model.
Tubular as depicted in figs. 1 and 2 struts pincers; Comprise left side pincers handle 6 and right pincers handle 4 and flexibility 8; Junction at left and right pincers handle 6,4 connects through sliding screw 3, is connected with left shell fragment 9 and right shell fragment 11 respectively on left and right pincers handle 6,4 medial surface, and left and right pincers handle is provided with anti-skidding stricture of vagina 12 on 6,4 lateral walls; The front end both sides of flexibility 8 are connected with left expanding bar 10 and right expanding bar 2 respectively; The end of left and right expanding bar 10,2 is connected with each other involutory expansion lobe 1, and the tail end of flexibility 8 and left and right pincers handle 6, hinge is connected with stretch 7 between 4, offers chute mouth 81 on the flexibility 8; Flexibility 81 is slided on sliding screw 3 through chute mouth 81; Pincers handle 6 sides, a left side offer through hole, offer and the corresponding screwed hole of through hole on the right pincers handle 4, and left side pincers handle 6 passes through hole with right pincers handle 4 through tie down screw 5 and screwed hole is fastening fixing.
The tubular of this utility model struts pincers; In use; User is held left side pincers handle 6 and is firmly pushed with right pincers handle 4, drives flexibility 8 with left and right pincers handle 6,4 mutually hinged stretch 7 and on sliding screw 3, moves, and flexibility 8 is moved backward; Expand outwardly thereby drive left and right expanding bar 10,2 and expand lobe 1, thereby realize the effect of expansion step by step.
With above-mentioned desirable embodiment according to this utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the description, must confirm its technical scope according to the claim scope.
