Abstract
The utility model provides an articular cartilage defect manufacturing tool, includes trephine and guide pin, the central part of trephine is provided with the guide pin mounting hole of boring the body coaxial line with the trephine, and the aperture of guide pin mounting hole is the same and for the normal size of guide pin external diameter and move the cooperation, the guide pin cartridge is in the guide pin mounting hole. By using the tool, the defect of the articular cartilage can be accurately positioned, and the problems of overlarge bone taking depth and even full-layer bone taking caused by insufficient clinical experience are effectively solved.
Description
Technical field
This utility model belongs to medical apparatus and instruments, particularly a kind of ossa articularia cartilage defect fabrication tool that uses in the ossa articularia cartilage lesion surgical operation for the treatment of.
Background technology
The ossa articularia cartilage lesion is a kind of common disease, adopts surgical operation therapy usually, in surgical operation, at first needs the ossa articularia cartilage is made damaged, then the pathological changes cartilage is replaced.Existing ossa articularia cartilage defect fabrication tool is a trepan, and handle that described trepan is connected by drill body, with drill body upper end and the band saw dentation drill bit that is positioned at the drill body lower end are formed.Clinical use shows that there is following problem in this kind ossa articularia cartilage defect fabrication tool: (1) location is inaccurate, causes and gets the bone direction and can not be guaranteed; (2) get the bone degree of depth and rule of thumb judge, for the insufficient doctor of clinical experience, it is excessive the bone degree of depth often to occur getting, even holostrome gets bone, certainly will make patient's wound big like this, hemorrhage many, the bone recovery time lengthening.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of improved ossa articularia cartilage defect fabrication tool is provided, to solve accurate location and accurately to judge the technical problem of getting the bone degree of depth.
Ossa articularia cartilage defect fabrication tool described in the utility model, comprise trepan and guide pin, the centre of described trepan is provided with the guide pin installing hole with trepan drill body coaxial line, the nominal dimension of the aperture of guide pin installing hole and guide pin external diameter is identical and for movingly, described guide pin is inserted in the guide pin installing hole.
Get the bone degree of depth in order in use accurately to judge, the lateral surface of described trepan drill bit is provided with graduation mark.
Ossa articularia cartilage defect fabrication tool described in the utility model, its guide pin is made of cylindric needle body and coniform syringe needle, and coniform syringe needle is fixed on the lower end of cylindric needle body.Described " coniform syringe needle is fixed on the lower end of cylindric needle body " comprises following two kinds of versions: coniform syringe needle and cylindric needle body are connected; Coniform syringe needle and cylindric needle body are integrated.
In order to satisfy the intensity that guarantees guide pin and trepan under the prerequisite of requirements of operation, the external diameter of the cylindric needle body of described guide pin is 2mm～5mm, and the external diameter of described trepan drill body is 5mm～10mm.
The utlity model has following beneficial effect:
1,, thereby in that being made, the ossa articularia cartilage can realize accurate the location when damaged because ossa articularia cartilage defect fabrication tool described in the utility model is provided with guide pin.
2, because the lateral surface of the trepan drill bit of ossa articularia cartilage defect fabrication tool described in the utility model is provided with graduation mark, thereby can judge according to graduation mark and get the bone degree of depth, efficiently solve cause because of clinical experience is not enough to get the bone degree of depth excessive, even holostrome is got the problem of bone.
3, because the lateral surface of the trepan drill bit of ossa articularia cartilage defect fabrication tool described in the utility model is provided with graduation mark, also can only make cartilage defect, for treatment provides more more options scheme.

The specific embodiment
Be described further below in conjunction with the structure and the use of accompanying drawing ossa articularia cartilage defect fabrication tool described in the utility model.
In the present embodiment, the structure of ossa articularia cartilage defect fabrication tool is made up of trepan 1 and guide pin 2 as shown in Figure 1.The shape of described trepan 1 and structure such as Fig. 2, shown in Figure 3, comprise handle 11, drill body 12 and drill bit 14, handle 11 is connected with the upper end of drill body 12, drill bit 14 is a band saw dentation drill bit, be positioned at the lower end of drill body 12 and be integrated with drill body, the centre of described trepan is provided with the guide pin installing hole 15 with trepan drill body coaxial line, and the lateral surface of described trepan drill bit 14 is provided with graduation mark 13.The shape of guide pin 2 and structure are made of columned needle body 21 and cone shape syringe needle 22 as Fig. 1, shown in Figure 4, and described coniform syringe needle 22 is positioned at the lower end of cylindric needle body 21 and is integrated with cylindric needle body, and the external diameter of cylindric needle body is 3mm.The nominal dimension of the aperture of the guide pin installing hole 15 on the described trepan and guide pin 2 external diameters is identical and for movingly, the external diameter of described trepan drill body is 6mm; The assembling mode of trepan 1 and guide pin 2: guide pin 2 is inserted in the guide pin installing hole 15 of trepan.
The ossa articularia cartilage is made when damaged the using method of ossa articularia cartilage defect fabrication tool described in the utility model: at first guide pin is inserted the osseocartilaginous lesion in joint, with trepan and guide pin combination, can carry out the cartilage defect manufacturing operation then.
