Abstract
This utility model relates to a kind of gun-type rongeur, comprises pincers and lower pincers; And upper pincers tail end is connected with flexible handle through the first articulated elements, fixed handle is provided with the interface be connected with air suction pump, and fixed handle is provided with in lower pincers the pipeline be connected with interface; The lower articulation port place of lower pliers head end is provided with and exports with the suction pump of pipeline connection; The stage casing of upper pincers and lower pincers is horizontal bending.This device is connected with suction pump, by the suction pump outlet of lower pliers head end, oozing of blood position in operation is cleared up, simultaneously because the upper pincers of this device and the stage casing of lower pincers are horizontal bending, thus effectively can avoid the sight line interference owing to occurring when space constraint causes many people to operate, effectively reduce operation risk and operation easier, make patient's broad view in operation process, improve the success rate of operation, save the time.This device is applicable to spread and use.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of gun-type rongeur.
Background technology
Spinal column degenerative disorders is that its common kind is intervertebral disk hernia, spinal canal stenosis and slippage, and its common feature is the compressing causing dura mater or nerve root so modal type in spine disorders.Therefore in its operation, the important point carries out the excision decompression of vertebral plate, as everyone knows, owing to having blood vessel, spinal cord and nerve around spinal column, so when carrying out spinal surgery operation can not as traditional bone surgery carrying out drastically, what light and handy, the favourable instrument of normal needs carried out spinal column and surrounding tissue is separated excision.Rongeur, laminectomy rongeur, osteotome and abrasive drilling are exactly the apparatus commonly used in operation.In addition because have the existence of dura mater and spinal cord below vertebral plate, so when in the end opening canalis spinalis, laminectomy rongeur is wherein most important instrument.
Laminectomy rongeur, also gun-type rongeur is cried, can be divided into multiple according to the thickness of its length and rifle sword and angle, wherein in lumbar vertebra, multiplex sword thickness is 5mm/3mm, the rifle pincers at 130 °/90 ° of angles, and in cervical vertebra and thoracic vertebra operation, multiplex sword is thick be 2mm/1mm, the rifle such as 110 °/130 ° of angles clamps, because less in peridural space, this position, also little to the space of the utilization of rifle pincers.If so rifle pincers smaller and more exquisite, light, effective utilization can just seem very important.
When carrying out spinal operation decompression, especially, when anterior cervical operation or the passage menisectomy decompression of lumbar vertebra Wicresoft, its surgical field of view is less, limited space, present situation current is clinically that a people uses suction apparatus attracts oozing of blood, and an other people carries out decompression operation with rifle pincers in limited space.Usually due to the restriction in space, can not two people operate simultaneously, time have mutual interference phenomenon to occur.Or after waiting for that suction pump exits, rifle pincers enter operating field again, but now surgical field of view, usually because oozing of blood shows unclear once more, adds operational risk and difficulty to operator.In addition because rifle clamp handle is kept straight on, so the hand of operator is after grasping rifle pincers, the visual field in deep can be caused to be obstructed, be unfavorable for carrying out smoothly of operation.
Utility model content
The purpose of this utility model is to overcome the shortcoming existed in above-mentioned prior art, provides a kind of gun-type rongeur, has patient's broad view, can clear up the advantage of oozing of blood in time.
For achieving the above object, this utility model by the following technical solutions: comprising to cooperatively interact carries out the upper pincers of translational motion and lower pincers; And upper pincers tail end is connected with flexible handle through the first articulated elements, the back segment of lower pincers forms fixed handle in the mode of downward lateral buckling; Flexible handle and fixed handle arranged in a crossed manner, and cross point to be provided with by both the second hinged articulated elements, between flexible handle and fixed handle, to be provided with support spring;
Described fixed handle is provided with the interface be connected with air suction pump, and fixed handle is provided with in lower pincers the pipeline be connected with interface;
Described lower pliers head end is provided with lower articulation port, and lower articulation port place is provided with and exports with the suction pump of pipeline connection;
The stage casing of described upper pincers and lower pincers is horizontal bending.
The bending angle in the stage casing of described upper pincers and lower pincers is 25 ° ~ 35 °.
Described suction pump outlet is perpendicular with lower pincers.
Described fixed handle is provided with anti-skidding projection.
Described support spring is spring leaf.
This utility model has following beneficial effect: prior art of comparing, and this utility model is provided with by handle and lower pincers the pipeline be connected with interface, and the lower articulation port place of lower pliers head end is provided with and exports with the suction pump of pipeline connection; Thus this device can be connected with suction pump, by the suction pump outlet of lower pliers head end, oozing of blood position in operation is cleared up, simultaneously because the upper pincers of this device and the stage casing of lower pincers are horizontal bending, thus effectively can avoid the sight line interference owing to occurring when space constraint causes many people to operate, effectively reduce operation risk and operation easier, make patient's broad view in operation process, improve the success rate of operation, save the time.This device is applicable to spread and use.
Further, owing to fixed handle being provided with anti-skidding projection, thus produce skidding when preventing doctor from using, improve the accuracy of operation.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
See Fig. 1-2, this utility model comprises the upper pincers 1 and lower pincers 2 that can cooperatively interact and carry out translational motion; And upper pincers 1 tail end is connected with flexible handle 4 through the first articulated elements 8, the back segment of lower pincers 2 forms fixed handle 7 in the mode of downward lateral buckling; Flexible handle 4 and fixed handle 7 arranged in a crossed manner, and cross point to be provided with by both the second hinged articulated elements 9, between flexible handle 4 and fixed handle 7, to be provided with support spring 3; Fixed handle 7 is provided with the interface 11 be connected with air suction pump, and fixed handle 7 is provided with in lower pincers 2 pipeline be connected with interface 11; Lower pincers 2 head end is provided with lower articulation port 6, and lower articulation port 6 place be provided with and export 5 with the suction pump of pipeline connection; The stage casing of upper pincers 1 and lower pincers 2 is horizontal bending.The bending angle in the stage casing of upper pincers 1 and lower pincers 2 is 25 ° ~ 35 °.Suction pump outlet 5 is perpendicular with lower pincers 2.Fixed handle 7 is provided with anti-skidding protruding 10.Support spring 3 is spring leaf.
Using method: first suction pump is connected to by the road interface 11 place on fixed handle 7, open suction pump, by suction pump outlet 5 first by the oozing of blood exhaustion near wound, the opening and closing of adjusting device is carried out afterwards by controlling flexible handle 4, because the stage casing of upper pincers 1 and lower pincers 2 is horizontal bending, thus patient's wide visual field more can be left for.Band is after operation completes, then opens suction pump and exhausted by oozing of blood, after complete operation, sew up wound.
This device, if dextromanuality, is partial to right side, the remote left side of left handedness, so just can by remote for the hands at rear side, to visual field slot milling.Simultaneously the suction pump in front can carry out sclerotin and stinging of soft tissue is removed very soon after clean blood, thus can improve procedure efficiency.
