Second portion is for inserting through rod 2, as shown in Figure 2, described external diameter of inserting through rod 2 is slightly less than the internal diameter of described hollow boring bit 1, can insert inserting the tail end of through rod 2 from hollow boring bit 1, the cylindrical shape cartilaginous tissue that drills through from the joint can be sent from hollow boring bit 1 front end.Described front end of inserting through rod 2 is provided with wooden termination 21, and the front end of described wooden termination is provided with the concave inward structure that the degree of depth is 2mm.
Third part is an outer sleeve 3, as shown in Figure 3, its internal diameter is slightly larger than the external diameter of described hollow boring bit 1, described hollow boring bit 1 is placed described outer sleeve 3, when the front end of described outer sleeve 3 is concordant with the front end of hollow boring bit 1, tail end is just concordant with 0 scale of described hollow boring bit 1 rear scale, is convenient to the degree of depth that enters at the described hollow boring bit 1 of external observation.
The 4th part is for probeing into through rod 4, as shown in Figure 4, the described external diameter that probes into through rod 4 is slightly less than the internal diameter of described outer sleeve 3, probe into after through rod 4 inserts outer sleeves 3 described, both can combine closely, front end is provided with pyramid type termination 41, is convenient to both coalitions and enters articular cavity, can reduce tissue injury as much as possible simultaneously.
The 5th part is a connector 5, as shown in Fig. 5,6, front end is provided with the hollow cylinder 51 of groove, the inwall of described hollow cylinder is evenly distributed with axial notch 512, the mutual interlock of raised line on described groove and hollow-core construction 16 outer walls makes described hollow boring bit 1 diametrically opposed fixing with connector 5.The outside of described hollow cylinder 51 also is provided with the sleeve pipe 52 that has female thread, the rear end of the front end of described hollow cylinder 51 and sleeve pipe 52 interlocks by the end face 511,521 of projection respectively, described sleeve pipe 52 is played half restriction, after the external screw thread 15 of female thread by described sleeve pipe 52 and hollow boring bit 1 locks, described hollow joint 16 and described hollow cylinder 51 can be combined closely.The rear end of described hollow cylinder 51 is provided with conversion and connects handle 53, connects handle by described conversion and can connect quick change handle or electric drill, increases operation efficient.
The 6th part is inner sleeve (not indicating in the drawings), and described inner sleeve is identical with outer sleeve 3 structures, and just external diameter is all identical with described hollow boring bit external diameter and internal diameter.
Based on said structure, it is as follows to adopt this utility model to carry out the operating process of cartilage transplantation:
1, detects under the arthroscope, determine cartilage injury's defect area size and determine to get bony site and what, and the cartilage defect zone is handled well, for the bone cartilage transplantation is got ready.
2, with the following location of arthroscope, cut a skin incision that is about 0.5cm with small blade, the tissue forceps passivity is separated subcutaneous tissue and joint capsule, enters in the articular cavity.
3, will probe into through rod 4 and insert in the outer sleeve 3, together enter in the articular cavity from skin incisions then, keep outer sleeve 3 position differences again, will probe into through rod 4 and take out.
4, the connecting device with hollow boring bit 1 afterbody is connected with union joint, after firmly, again conversion is connect handle 53 and connect upward quick change handle or electric drill, then hollow boring bit 1 is inserted in the outer sleeve 3, entering articular cavity gets bony site and manually rotates and get bone or electric drill is got bone fast, utilize the observation of EXT scale scale to enter the degree of depth, the degree of depth of generally getting bone cartilage bar is 1.5-2.0cm.Then outer sleeve 3 and hollow boring bit 1 taken out, again outer sleeve 3 is taken out after perhaps repeatedly getting bone.
5, with outer sleeve 3 with probe into through rod 4 combination once more, enter articular cavity cartilage defect position, taking-up probes into through rod 4, inner sleeve that then will be identical with the hollow boring bit external diameter inserts in the outer sleeve 3, get the bone hole of boring respective depth with another solid bit (can adopt general common medical drill bit) in the cartilage defect zone again, hollow boring bit internal diameter when the external diameter of current solid bit is got bone with the first time is identical, takes out solid bit and inner sleeve then.
6, the connector with previous hollow boring bit 1 takes off, expose hollow space, again insert again and aim at bone holes (the cartilage bar when get bone for the first time this moment is still stayed in the parts I) in the outer sleeve 3, the cartilage bar is pushed to the marrow in the hole, until concordant with articular cartilage face with the described through rod 2 of inserting.
External diameter is all identical with the interior external diameter of the hollow boring bit of getting for the first time bone in the described inner sleeve, can play the effect of stablizing drill bit, because the external diameter of for the second time used solid bit is identical with for the first time used internal diameter, promptly and 3 of outer sleeves have the gap, then involutory between the two defective tightness, when boring, occur skew easily, therefore in bore bone hole, can play the effect of stablizing solid bit by inner sleeve.
This utility model is mainly used in and carries out Wicresoft operation under the arthroscope, the big wound of having avoided the incision surgery operation to cause, simultaneously of the present utility model each also can be used for open surgery and manipulate, can save operation time greatly, improve operation efficient.The probability and the degree of cartilage can effectively be avoided damaging in described wooden termination 21 with concave inward structure when the bone cartilage bar in the hollow boring bit is sent, play the effect of protection cartilage.By the tail end at hollow boring bit 1 connector 5 is set, hollow boring bit 1 can be connected with quick change handle or electric drill, significantly the operation that improves is kept forging ahead the time of bone, because the operating time obviously shortens, can effectively reduce getting the damage in bone zone simultaneously.
More than Wicresoft provided by the utility model joint internal skeleton cartilage transplantation device is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
