The utility model discloses a kind of laminectomy rongeur, comprise: clamp handle and chela, described chela comprises chela and lower chela, described upper chela and described lower chela are engaged, the head of described lower chela is bent upwards and forms a bending section, on described bending section, offer and attract hole, the inside of described lower chela offers drainage tube chamber, in described drainage tube chamber, be inserted with negative-pressure drainage tube, the head end of described negative-pressure drainage tube is connected with described attraction hole, and the end of described negative-pressure drainage tube is connected with negative pressure suction device.By the way, this utility model can improve the definition of surgical field of view and the degree of accuracy of operation, reduces and pollutes, and bacteria growing inhibiting, can directly accelerate wound healing, can reduce the possibility of obstruction simultaneously, increases the intensity attracting.
Description
Technical field
This utility model relates to medical apparatus field, particularly relates to a kind of laminectomy rongeur.
Background technology
Along with the continuous aggravation of domestic aged tendency of population, the infirmities of age that aging brings increases day by day, the lumbar spinal stenosis that degenerative lumbar causes and prolapse of lumbar intervertebral disc, just progressively dangerous our health.So in the medical research in this field, comprise on modus operandi, all obtained huge progress.All modus operandis comprise: PLIF, ALIF and TLIF etc., the difference of these modus operandis is mainly reflected in different operative approaches, but their all objects, all to wish to pass through operation pathway safely and effectively, reach between vertebral body, remove to extract this vertebral pulp wherein, because vertebral pulp causes the most key key element of lumbago and skelalgia often.In operative approach, very important link is to sting except local vertebral plate, opens local operation path.
Thereby, how to sting except local vertebral plate, set up effective surgical pathway, be the focus of work of spinal surgery, in this type of operation, the proprietary operating theater instruments that we tend to use is laminectomy rongeur.
Vertebral plate is stung the process of removing, need spinal surgeons to have abundant clinical experience, nonetheless, still need part to have surgical field of view clearly, but local hemorrhage often clinically, causes the visual field unclear, can not well differentiate the boundary of canalis spinalis and vertebral plate in operation process, often cause dural sac damage, even have Spinal Cord to cause the possibility of paralysis.In addition, existing laminectomy rongeur easily stops up, and causes germ contamination.
Utility model content
The technical problem that this utility model mainly solves is to provide a kind of laminectomy rongeur, can improve the definition of surgical field of view and the degree of accuracy of operation, reduces and pollutes, bacteria growing inhibiting, can directly accelerate wound healing, can reduce the possibility of obstruction simultaneously, increase the intensity attracting.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: a kind of laminectomy rongeur is provided, comprise: clamp handle and chela, described chela comprises chela and lower chela, described upper chela and described lower chela are engaged, the head of described lower chela is bent upwards and forms a bending section, on described bending section, offer and attract hole, the inside of described lower chela offers drainage tube chamber, in described drainage tube chamber, be inserted with negative-pressure drainage tube, the head end of described negative-pressure drainage tube is connected with described attraction hole, the end of described negative-pressure drainage tube is connected with negative pressure suction device.
In preferred embodiment of this utility model, described attraction hole is through hole, has two, and its perforate direction is in the two sides of lower chela.
In preferred embodiment of this utility model, the length of described lower chela is longer than the length of described upper chela.
The beneficial effects of the utility model are: by existing laminectomy rongeur is done to certain improvement, inside at existing laminectomy rongeur increases the negative-pressure drainage tube that connects negative pressure suction device, remove hemorrhage in surgical field of view, increase the definition of surgical field of view, reduce and pollute, bacteria growing inhibiting, can directly accelerate wound healing; In addition, also, by increasing twin-channel attraction hole at the head end of vertebral plate pincers, to reduce the possibility of obstruction, increase the intensity attracting.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of laminectomy rongeur one preferred embodiment of this utility model;
In accompanying drawing, the labelling of each parts is as follows: 1, clamp handle, 2, chela, 21, upper chela, 22, lower chela, 221, bending section, 222, attract hole, 223, drainage tube chamber, 3, negative-pressure drainage tube.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, this utility model embodiment comprises:
A kind of laminectomy rongeur, comprise: clamp handle 1 and chela 2, described chela 2 comprises chela 21 and lower chela 22, described upper chela 21 and described lower chela 22 are engaged, the head of described lower chela 22 is bent upwards and forms a bending section 221, on described bending section 221, offer two and attract hole 222, the inside of described lower chela 22 offers drainage tube chamber 223, in described drainage tube chamber 223, be inserted with negative-pressure drainage tube 3, the head end of described negative-pressure drainage tube 3 is connected with described attraction hole 222, the end of described negative-pressure drainage tube 3 is connected with negative pressure suction device, at the inner negative pressure suction device that connects of vertebral plate pincers, by clean the hemorrhage removing in surgical field of view, improve the definition of surgical field of view, provide tissue boundary clearly to operator, the position of dissecting with clear and definite each operation, improve the degree of accuracy of operation.
Described attraction hole 222 is through hole, and its perforate direction, in the two sides of lower chela 22, can be avoided stopping up, and increases the intensity attracting.
The length of described lower chela 22 is longer than the length of described upper chela 21.
In operation process, use special negative pressure suction device to produce certain negative pressure, act on wound surface by the attraction hole 222 of negative-pressure drainage tube 3 and lower chela head end, can remove hemorrhage in surgical field of view, increase the definition of surgical field of view, the blood circulation that can accelerate wound site simultaneously, significantly promote that new vessels enters wound surface, stimulate the growth of granulation tissue, fully drain, alleviates edema, reduce and pollute, bacteria growing inhibiting, can directly accelerate wound healing, or creates conditions for surgical repair.A kind of efficient, simple, economical, the pure physiotherapy of wound healing.
This utility model has disclosed a kind of laminectomy rongeur, by existing laminectomy rongeur is done to certain improvement, inside at existing laminectomy rongeur increases the negative-pressure drainage tube that connects negative pressure suction device, remove hemorrhage in surgical field of view, increase the definition of surgical field of view, reduce and pollute, bacteria growing inhibiting, can directly accelerate wound healing; In addition, also, by increasing twin-channel attraction hole at the head end of vertebral plate pincers, to reduce the possibility of obstruction, increase the intensity attracting.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
