Abstract
The utility model relates to a caput femoris core decompression device, belongs to the technical field of medical appliance and aims to resolve technical problems of providing a caput femoris core decompression device which is minimally invasive, has small interference on blood vessels and nerves surrounding caput femoris and is convenient and fast in surgery. The caput femoris core decompression device consists of a guide sleeve and a flexible driller, the guide sleeve is a circular pipe with the closed front end and the opened rear end, a side opening is disposed on the side wall of the front end of the guide sleeve and is in smooth transition connection with an inner cavity of the sleeve, the flexible driller is a spring driller body, and the outer diameter of the flexible driller matches with the diameter of the inner cavity of the guide sleeve. The caput femoris core decompression device has the advantages that during surgery, by aid of the caput femoris core decompression device, a doctor can drill from a position below greater trochanter of the caput femoris to a decompression position of the caput femoris, the guide sleeve is inserted into a drilled hole, the flexible driller extends out from the side opening of the guide sleeve to curette and cut, and all-around operation can be performed by means of continuously steering the guide sleeve. The caput femoris core decompression device is simple and practical, avoids damaging blood vessels and nerves surrounding the caput femoris during surgery, and is also extremely simple and fast.
Description
Technical field
This utility model relates to a kind of operating theater instruments for the treatment of femur head necrosis, belongs to the orthopedic medical device technical field.
Background technology
Femur head necrosis claims aseptic necrosis of femoral head again, or ischemic necrosis of femoral head, is that the local blood fortune of femoral head that causes owing to multiple reason is bad, thereby causes a kind of pathological changes of the further ischemia of osteocyte, necrosis, bone trabecula fracture, collapse of the femoral head.Pathogenic factor is not bright so far.Common inducement has wound, drinks for a long time, excessive use hormone, acetabular dysplasia etc.Its sickness rate has the trend that increases gradually.According to incompletely statistics, present whole world femur head necrosis 3,000 ten thousand people, China has 4,000,000 people approximately.Patient's onset shows as dull pain, the dull pain in joint around hip joint or its more, and the activity postemphasis further develops the dysfunction that can cause hip joint, is a kind of disability rate disease with high.Can occur the disorder of trabecula of femoral head structural arrangement, fracture in early days, femoral head is rough, clinically with or without limitation pain.Little cystis degeneration can occur with the disease progression femoral head is inner, capsule becomes the density unevenness around the district.Occur trabecular bone structure disorder, sparse or fuzzy subsequently, also tiny subsiding can occur, and engender that the bone trabecula part-structure disappears, bone density is inhomogeneous, and the crack, joint narrows down, and clinical manifestation pain, limping, joint motion are limited etc.Last capital form, structure obviously change, and occur subsiding joint space disappearance etc. on a large scale.Clinical manifestation is pain, dysfunction, limitation of activity etc.
Core decompression is a kind of effective clinical technology of treatment aseptic necrosis of femoral head, operation can be lowered the intrinsic pressure and local flesh and blood stream of improvement of bone marrow, and be applied to the patient that the x line changes, result's curative effect in not having the patient of collapse of the femoral head is affirmed, even the patient of subsiding in early days with " meniscus sign " is arranged, clinical effectiveness is in the recent period arranged also significantly at the x line.In implementing the core decompression operation, generally take at present to implement to open or hole on the femoral head surface, strike off sequestrum with curet then, because a large amount of muscle, ligament, blood vessel and neural the distribution are arranged at the anatomical position place of the shallow table of femoral head, must peel off even cut off in the operation, even repairing also, postoperative will inevitably cause very big damage to the blood vessel and the nerve at this place, make the femoral head that just lacks blood supply originally make the matter worse more, have a strong impact on therapeutic effect, also be unfavorable for very much postoperative recovery.
Summary of the invention
Utility model technical problem to be solved provide a kind of Wicresoft, to blood vessel around the femoral head and neural few, the facilitating operation femoral head core decompression device efficiently that disturbs.
The technical scheme that solves the problems of the technologies described above is:
A kind of femoral head core decompression device, it is made up of guide thimble, soft brill, guide thimble is the pipe of front end sealing, open rearward end, on the front end side wall of guide thimble, lateral openings is arranged, the bore of lateral openings is identical with the intracavity diameter of guide thimble, lateral openings is connected with the inner chamber rounding off of guide thimble, and soft brill is the spring drill body, and the external diameter of soft brill and the intracavity diameter of guide thimble are complementary.
Above-mentioned femoral head core decompression device, the external diameter 9-12mm of described guide thimble, internal diameter 6-9mm, long 120-150mm.
Above-mentioned femoral head core decompression device, the drill bit of described soft brill and spring drill body are for removably connecting.
The beneficial effects of the utility model are: adopt in operation that boring arrives femoral head decompression position below the femoral greater trochanter, guide thimble inserts boring, soft brill stretches out from the lateral openings of guide thimble polishes and cuts, can carry out omnibearing operation by constantly turning to of guide thimble, because femoral greater trochanter is positioned at big leg outer side, blood vessel and nerve are seldom, hole simultaneously and perform the operation and only need very little otch, therefore avoided near blood vessel the femoral head and neural damage, operation is also very fast simple, this utility model is simple in structure, make easily, result of use is remarkable, is the new apparatus of implementing the operation of femoral head core decompression.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is user mode figure of the present utility model.
Labelling is as follows among the figure: guide thimble 1, soft brill 2, lateral openings 3, spring drill body 4, drill bit 5, femoral head 6, femoral greater trochanter 7, femur wall 8.
The specific embodiment
Show among Fig. 1,2 that this utility model is made up of guide thimble 1, soft brill 2.
The external diameter 10mm of the guide thimble 1 of an embodiment of the present utility model, internal diameter 7mm, long 130mm.
This utility model in use, at first cut a little otch facing to the position of femoral greater trochanter 7 at big leg outer side, peel off muscle and ligament, expose femur wall 8, on femur wall 8, aim at the direction boring of femoral head 6, the aperture is slightly larger than the external diameter of guide thimble 1, and drilling depth will arrive the position that femoral head 6 needs curet.After boring is finished, guide thimble 1 is inserted in the boring, soft brill 2 stretches out from the lateral openings 3 of guide thimble 1, and femoral head 6 is carried out curet and cutting.After reaching the curet degree of depth, rotate guide thimble 1, soft brill 2 begins another direction is carried out curet, and so continuous rotation guide thimble 1 just can be realized omnibearing work.The bone slag that scrapes is drawn out boring with instrument, and water is rinsed well again, inserts bone graft, and operation can be finished.Above-mentioned work can be carried out under X-ray monitors.
