Abstract
The utility model discloses a shoulder arthroscopy clearance measurement instrument which comprises a first test rod and a second test rod. The outer side of the top end of the first test rod and the outer side of the top end of the second test rod are respectively provided with a mini-type contact rod. The upper portion of the first test rod is connected with the upper portion of the second test rod through a clamping buckle in an intersecting mode. The clamping buckle is a rotating pivot of the first test rod and the second test rod. An arc tooth-shaped lock is arranged at the lower portion of the first test rod. A tooth-shaped buckle matched with the tooth-shaped lock is arranged at the lower portion of the second test rod. A graduated scale is arranged on the tooth-shaped lock. A scale indicating pointer is arranged on the tooth-shaped buckle. The lower end of the first test rod and the lower end of the second test rod are respectively provided with a handle. The shoulder arthroscopy clearance measurement instrument has the advantages that the intra-articular clearance can be directly measured by the naked eyes from the extra-articular portion through the shoulder arthroscopy clearance measurement instrument, so that the clearance below the acromion is accurately measured, the bone mass is accurately and truly ground away during an acromion forming operation, and the better operation effect is achieved.
Description
Technical field
This utility model discloses a kind of shoulder joint mirror clearance meter, is mainly used in the measurement in gap under acromion in acromioplasty under shoulder joint mirror.
Background technology
" scapulohumeral periarthritis " this noun is widely known in China substantially.A lot of common people, even part doctor is summed up as " scapulohumeral periarthritis " the shoulder arthralgia of unknown cause and movable function obstacle.In fact, scapulohumeral periarthritis can not understanding from literal merely.According to the definition of shoulder elbow surgeon association of the U.S., scapulohumeral periarthritis is that a class causes the adhesive synovitis that Glenohumeral joint is stiff, show as shoulder joint pain around, the active of shoulder joint all directions and passive range of motion reduce, and imaging examination is except the illness of the Non Apparent Abnormality of bone amount minimizing.This disease is always more chaotic in name.External " congealed shoulder " or " adhesive synovitis " these two titles that use at present more.China still extensively continues to use " scapulohumeral periarthritis " this name so far.
The treatment of scapulohumeral periarthritis mainly contains two objects: alleviating pain and recovery range of motion.Traditional Therapeutic Method is expectant treatment mostly, comprise under systemic administration (NSAIDs and glucocorticoid), partial closure, medicine for external use, naturopathy, anesthesia that maneuver is loosened and TCM Therapy [6] etc., but these treatments are only effective to some patients were, some patients were is through above treatment, and still poor effect is even invalid.
Because scapulohumeral periarthritis is long by the course of disease of expectant treatment, patient's pain is more acute, have a strong impact on daily life, even and farthest recovered by the expectant treatment state of an illness, the case of 60 % that still have an appointment can not be recovered normally, to cause permanent dysfunction completely, patient's Long-term taking medicine, physical therapy, acupuncture, but cannot solve dysfunction, cause great medical resource waste, national economy is caused to very large loss.Therefore in recent years, increasing doctor advocates the loosening therapy of performing the operation.Along with the continuous renewal of arthroscopic techniques, shoulder joint mirror has been obtained development at full speed in recent years.At present for scapulohumeral periarthritis patient, the cleaning art of loosening under arthroscope, mainly comprise acromioplasty (needing to clear up subacromial bursa before shaping), joint capsule and around release of ligament (coracohumeral ligament of loosening, broad-mouthed receptacle for holding liquid upper arm arnold ligament, biceps tendon and around joint capsule etc.).
For the patient with acromion impingement sign, need acromioplasty under row shoulder joint mirror, this part patient, the preoperative situation that need to understand acromion, the general method of understanding at present acromion form is the preoperative supraspinatus outlet position X sheet of taking the photograph, and can judge acromion shape and typing thereof according to X sheet.Can provide certain foundation for acromioplasty under shoulder joint mirror.But supraspinatus outlet bit slice is a kind of special bit slice that is exclusively used in shoulder joint, a lot of hospital radiological departments cannot be taken or position is put nonstandardly, cause preoperative preparation deficiency.And X sheet is only a two-dimensional imaging, need worn bone amount how many for acromioplasty under arthroscope, is the hyperosteogeny of acromion hypertrophy specifically at which position? front side, outside or outside back outside? cannot determine.Therefore needing in the preoperative judge accurately bone amount that acromion needs are worn and the particular location of worn acromion sclerotin, this image with regard to a three-dimensional reconstruction of needs instructs this work as far as possible.By preoperative scanning shoulder joint CT, utilize Mimics14.0 software three-dimensional reconstruction acromion, by a series of operation, determine the position and the bone amount that need worn acromion sclerotin, thereby instruct more personalized acromion plastic operation, reach better surgical effect.
Can preoperative plan be quantitative by Digitization Software, but how in shoulder joint mirror art, to embody? how does operation pass judgment on bone amount worn under acromion? traditional method is roughly to estimate gap under postoperative acromion by the diameter of probe or bistrique.The shortcoming of this way be measure accurate not, estimation often cause deviation, to make effect not ideal enough, and there is no at present simple in structure, wieldy survey tool yet.
Summary of the invention
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of and measures precisely, really accomplishes that under shoulder joint mirror, acromioplasty is quantitative, the shoulder joint mirror clearance meter of simple in structure, easy operating.
This utility model is achieved in that a kind of shoulder joint mirror clearance meter, it is characterized in that: comprise the first reference test bar, the second reference test bar, the outside, top of described the first reference test bar, the outside, top of the second reference test bar are respectively equipped with miniature feeler lever, described the first reference test bar is intersected and is connected by buckle with the top of the second reference test bar, and described buckle is the pivot point of described the first reference test bar and the second reference test bar; The bottom of described the first reference test bar is provided with arc profile of tooth lock, and the bottom of described the second reference test bar is provided with and the phase-locked profile of tooth button coordinating of described profile of tooth; Described profile of tooth is locked and is provided with rule, and described profile of tooth is buckled and is provided with graduation indication pin; The lower end of described the first reference test bar, the lower end of the second reference test bar are respectively equipped with handle.
Described graduation indication pin is connected on the head end that described profile of tooth buckles, and described graduation indication pin is the triangle that drift angle points to described rule.
Described buckle is positioned at 1/4 place of described the first reference test bar, the second reference test bar.
The beneficial effects of the utility model are: by IA gap length, directly from joint, with the naked eye measure by this utility model, thereby record accurately gap under acromion, really accomplish that the accurate bone amount of acromioplasty is worn, to reach better surgical effect.
