Abstract
The mainly design for releasing when when protecting surrounding soft tissue hold-down screw being screwed into fixing vertebral body during the rod operation of Via Posterior Spinal Approach nail of arc laminectomy retractor disclosed in this utility model.Comprise non-slip hook pull bar (1), handle (2) and semi-ring slot type arc guard bar (3); described non-slip hook pull bar is connected with one end of handle; the other end of handle is connected with semi-ring slot type arc guard bar, and the front end of semi-ring slot type arc guard bar is arc-shaped draw hook head (4).Soft tissue can retract by this utility model quickly and easily, reaches the object reducing surgical injury, shorten operating time, increase success rate of operation, convenient operation.Whole design have sturdy and durable, easy and simple to handle, reduce surgical injury, the feature such as with low cost.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of arc laminectomy retractor.
Background technology
Spinal vertebral fracture is the commonly encountered diseases of spinal surgery, has a strong impact on the normal work of patient, living and studying, often leaving over serious complication, causing no small misery to patient as dealt with improperly.At present, the surgical operation therapy of spine disorders is fixed as clinical more employing with the nail-stick system of Via Posterior Spinal Approach, needs to be screwed in vertebral body by pedicle screw accurately in operation.Because on rear side of vertebral body, soft tissue enriches, and along with people are to the pursuit of less invasive techniques, require that otch is more and more less, in the process being screwed into pedicle screw, thus need soft tissue to retract, to expose tissue.Otherwise serious strand being caused to frustrate infringement to otch soft tissue because exposing the unclear location misalignment of pedicle screw that causes, producing the postoperative failed syndrome of spinal column.Clinical at present also do not have special operating theater instruments, and the operating theater instruments substituted needs larger strength soft tissue could to be retracted, not only poor to soft tissue protectiveness, easily causes iatrogenic damage, and complex operation, increases operation easier.Under this present situation, urgently research and develop a kind of special equipment, realize carrying out vertebral body screw placement under minimal incision *, avoid soft tissue injury, reduce iatrogenic infringement.
Summary of the invention
Namely the purpose of this utility model produces thus, proposes a kind of arc laminectomy retractor.Quickly and easily soft tissue can be retracted, reach the object reducing surgical injury, shorten operating time, increase success rate of operation, convenient operation.
For achieving the above object; the technical scheme that this utility model is taked is: a kind of arc laminectomy retractor comprises non-slip hook pull bar, handle, semi-ring slot type arc guard bar; described non-slip hook pull bar is connected with one end of handle; the other end of handle is connected with semi-ring slot type arc guard bar, and the front end of semi-ring slot type arc guard bar is arc-shaped draw hook head.
Non-slip hook pull bar described in the utility model designs for solid flat, is reverse 180 ° is connected with described handle.
Handle described in the utility model designs for solid flat, and surface has annular knurl decorative pattern.
Semi-ring slot type arc guard bar described in the utility model is solid semicircular configuration, is gradual arc by handle to retractor head.
Retractor head described in the utility model is solid construction, curved gradually fine texture.
This utility model is reasonable in design, non-slip hook pull bar and handle are solid flat design, non-slip hook pull bar and handle are reverse 180 ° and are connected, handle surfaces is provided with annular knurl decorative pattern, increase the frictional force of handle and hands in case grip more firm while, finger may be stuck in Opposite direction connection place, prevents apparatus landing from hands; The core of the design is semi-ring slot type arc guard bar; for solid semicircular configuration, effectively screw and surrounding soft tissue can being isolated, avoiding the cutting to soft tissue when being screwed into screw; effectively protect soft tissue and the tissue such as blood vessel, nerve of surrounding, reduce the injury to soft tissue.Gradually the operator that is designed to of arc provides surgical field of view more clearly, for safety, accurately vertebra localization provide possibility.Retractor head is gradually thin arc passivity structure, can reduce when entering human body organizing the injury caused to increase its sharpness simultaneously.Whole design can steadily, continue pull open and protect the skin around operative site, have sturdy and durable, easy and simple to handle, reduce surgical injury, the feature such as with low cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.
In figure: 1, non-slip hook pull bar, 2, handle, 3, semi-ring slot type arc guard bar, 4, retractor head.
Detailed description of the invention
By reference to the accompanying drawings, embodiment of the present utility model is provided as follows:
As shown in Figure 1: a kind of arc laminectomy retractor comprises non-slip hook pull bar 1, handle 2, semi-ring slot type arc guard bar 3 and retractor head 4.Described non-slip hook pull bar 1 and handle 2 are solid flat design, and the long 16cm of handle, wide 3cm, surface is provided with annular knurl decorative pattern, not only attractive in appearance, can also increase the frictional force of handle of a knife and hands, and unlikely handle skids in hands.Non-slip hook pull bar 1 is fixedly connected on the rear end of handle 2, and is reverse 180 ° with handle and is connected.The annular knurl decorative pattern that handle 2 surface has, increase the frictional force of handle and hands in case grip more firm while, point in the process of tractive and may be stuck in Opposite direction connection place, prevent apparatus landing from hands.Long 8 centimetres of semi-ring slot type arc guard bar 3, the widest part 3 centimetres, is fixedly connected on the front end of handle 2, and in 100 ° of degree angles.Because pedicle screw implant time and center line have one 5 ~ 10 ° of angles, therefore, adopt 100 ° of angles that handle can be made to be parallel to lower back skin plane.Described semi-ring slot type arc guard bar 3 is solid semicircular configuration, and front end is arc-shaped draw hook head 4, and this retractor head 4 is also solid construction, long 0.5cm, curved gradually fine texture.Be gradual arc by handle to retractor head.Screw and surrounding soft tissue can be isolated by semiorbicular design effectively; better protection soft tissue around; avoid the cutting to soft tissue when being screwed into screw, gradually the operator that is designed to of arc provides surgical field of view more clearly, is also convenient to being screwed into of vertebral body screw.The arc passivity design that retractor head 4 is gradually thin, so that better insert in soft tissue, reduces when entering human body organizing the injury caused.In the present embodiment, non-slip hook pull bar 1, handle 2 are also designed to solid, can be impose comparatively great at tractive.
During use, hold the handle and non-slip hook pull bar with annular knurl, after retractor head being inserted vertebral body lower edge, sled pressure handle and non-slip hook pull bar, utilize semi-ring slot type arc guard bar that surrounding soft tissue is retracted protection, exposes vertebral body, be screwed into screw.
