Abstract
The utility model relates to a dilating device for a vertebral column operation, which relates to a medical appliance, particularly to the appliance for surgery. The utility model solves the problems that in the existing pliers type dilating device, operated knife edge is pulled longer, and dilating effect is not good, so visual field and operative operation are influenced, etc. The dilating device for the vertebral column operation comprises two parallel side plates and two supporting rods, wherein the positions at two ends which are near to the upper edge of each of the side plates are respectively provided with clamping grooves and two ends of the supporting rods are respectively clamped in the clamping grooves of two side plates. The dilating device for the vertebral column operation of the utility model can be used for dilating surgery vertebral column operation muscles, and the utility model has the advantages of simple structure, easy processing and manufacture, low cost, convenient use, easy exposure of the operative operation and the visual field, favorable enhancement of operation quality, shortening of operation time and flexible operation. The width of an operation incision can be adjusted according to the requirement, and the knife edge length for placing the dilating device is relatively smaller.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and particularly the apparatus used of surgical operation is specially a kind of spinal operation dilator.
Background technology
When spinal column is had an operation, influence operation technique for fear of the muscular tissue of knife-edge part spinal column both sides, need the muscle of knife-edge part spinal column both sides is peeled off and strutted, spinal column both sides muscle struts a kind of jaw type dilator commonly used at present.This jaw type dilator need be positioned over respectively in the otch of upper/lower terminal at spinal operation position in use; Rely on the operation of handle that muscular tissue is separated to both sides, expose spinal column so that undergo surgery.Because need two jaw type dilators focal zone could be strutted, scalpel edge draws back longer, not only make the patient increase misery but also the difficult healing of postoperative; Simultaneously in operation process to focal zone to strut effect bad, influence the visual field, and handle also influences operation technique, increased operation risk.
Summary of the invention
This utility model solve scalpel edge that existing jaw type dilator exists draw back long, to strut effect bad, influences problems such as the visual field and operation technique, provides a kind of simple in structure, easy to operate spinal operation dilator.
This utility model is achieved through the following technical solutions: a kind of spinal operation dilator, comprise two blocks of parallel side plates and two support bars, the position at the close two ends of the top edge of every block of side plate has draw-in groove, and the two ends of support bar are connected to respectively in the draw-in groove of two blocks of side plates.During operation, earlier the muscle of spinal column both sides is peeled off, again biside plate is placed the spinal column both sides respectively, then support bar is connected on the biside plate, two support bars strut biside plate, and biside plate struts the muscle of spinal column both sides.Space between biside plate and two support bars is exactly the focal zone of operation.
The two ends of support bar have cannelure, and the support bar two ends are connected in the draw-in groove of biside plate by cannelure.Like this, support bar can realize more reliably to the strutting of biside plate, prevent to occur between the draw-in groove on support bar end and the side plate clamping when loosening side plate top along the slip of support bar.
Spinal operation dilator described in the utility model can be used for strutting of surgery spinal operation muscle, and it is simple in structure to be easy to processing and manufacturing, and cost is lower; Easy to use, be easy to appear the operation technique visual field, help improving the operation quality, shorten operating time; Flexible operation can be adjusted the width of operative incision as required, and it is less relatively to place the required knife edge length of this dilator.

The specific embodiment
The spinal operation dilator comprises two blocks of parallel side plates 1 and two support bars 3, and the position at the close two ends of the top edge of every block of side plate has draw-in groove 2, and the two ends of support bar 3 are connected to respectively in the draw-in groove 2 of two blocks of side plates 1.
The two ends of support bar 3 have cannelure 9, and the support bar two ends are connected in the draw-in groove 2 of biside plate 1 by cannelure 9.
The bolt 5 that support bar 3 is provided with the pole 4 of female thread by two ends and places head in the pole two ends to be provided with cannelure 9 constitutes, and bolt 5 links to each other with pole by screw thread, and the female thread at pole 4 two ends is reverse.Support bar adopts above-mentioned combinative structure, makes the adjustable length of support bar.In actual use, the bolt at two ends is outwards moved synchronously by rotating pole, thus the length that realizes regulating support bar, and then adjust distance between the biside plate, change the purpose of the outside dynamics that struts of biside plate.
Pole 4 middle parts of support bar 3 are provided with pin-and-hole 6.When needs rotation pole is regulated the length of support bar, can in this pin-and-hole, insert a lever, like this, be convenient to the rotation of pole.
Shaft part 10 in the cannelure 9 of bolt 5 heads of support bar is the square-section.Like this, when rotating pole 4, the shaft part 10 of square-section is stuck in the draw-in groove 2 on the side plate more fully, and when further avoiding pole to rotate, the bolt 5 at its two ends together rotates, thereby more convenient, realize the adjustment of support bar length reliably.
