Compared with prior art, the utility model tool has the following advantages:
When using the utility model, this device is placed in horizontal table top, again by one, knotting exercise line through elastic threads two ends after the ring of the training that is used for tiing a knot, regulate appropriate length, band soft metal rod y direction apply suitable power and carries out knotting and practise; If carry out degree of depth knotting training or examination, then can through the outside of ultrared jacket casing at flexible column.
(1) the utility model utilizes flexible column to the ultrared requirement of blocking the surgery knotting distinguishing trainee or examinee in real time and whether meeting specification, especially whether to meet the standard convention requirements such as knotting direction, firmly equilibrium, trainee is known and practises according to specification.
First, whether point-blank the utility model can distinguish the two hand forces of trainee or examinee and ligation point three in real time.Because knotting exercise or examination carry out on the ring for training of tiing a knot, therefore, ligation point is positioned on ring, to be fixed by ring and flexible column with ring, thus, whether point-blank whether two hand forces and ligation point three are just converted into two hand forces and flexible column point-blank, when on two hand forces and flexible column i.e. two hand forces and ligation point straight line, flexible column keeps original state, flexible column blocks the infrared ray of the first infrared transmitter and the transmitting of the second infrared transmitter simultaneously, first infrared switch and the second infrared switch are in off state, indicating circuit does not work, when two hand forces and flexible column i.e. two hand forces and ligation point not point-blank time, flexible column (ligation point) offsets under knotting is to the effect of the tension force that line produces, flexible column hides the infrared ray that incessantly the first infrared transmitter and the second infrared transmitter are launched, first infrared switch and the second infrared switch are in conducting state, indicating circuit works, the two hand forces of trainee or examinee and ligation point three are not point-blank, ligature is easily made to come off when firmly straining, the this time knotting exercise of trainee does not meet specification, the this time knotting of examinee is defective.
Secondly, the utility model can distinguish or judge whether trainee's two hands when toe-in is tightened up in training are firmly even, whether meet specification in real time; Whether whether examinee's two hands when toe-in is tightened up in examination firmly even, qualified.Because knotting exercise or examination carry out on the ring for training of tiing a knot, therefore, ligation point is positioned on ring, to be fixed by ring and flexible column with ring, when trainee or examinee two hands when tightening up toe-in are firmly even, flexible column keeps original state, and flexible column blocks the infrared ray of the first infrared transmitter and the transmitting of the second infrared transmitter simultaneously, first infrared switch and the second infrared switch are in off state, and indicating circuit does not work; When trainee or examinee two hands when tightening up toe-in are firmly uneven, flexible column offsets, hide the infrared ray that incessantly the first infrared transmitter and the second infrared transmitter are launched, first infrared switch and the second infrared switch are in conducting state, indicating circuit work, show that trainee or examinee two hands when tightening up toe-in are firmly uneven, an i.e. hand-tight proficiency pine, this very easily forms Slipped Clove Hitch and slippage, and the exercise of trainee does not meet specification, and this time knotting of examinee is defective.
(2) the utility model adopts the combination of the first infrared switch, the second infrared switch, flexible column and the technical characteristic for the pressure transducer that obtains flexible column axially loaded signal, not only can investigate trainee or the operation of examinee in flexible column vertical plane whether specification, trainee or the operation of examinee in the axial plane of flexible column whether specification can also be investigated.One in the two hand forces of trainee or examinee with force or two with force below or above ligation point and when pulling at tight knot binding, pressure transducer for obtaining flexible column axially loaded signal will sense the axial force that ligature produces flexible column, therefore, if pressure transducer produces induced signal, the two hand forces of trainee or examinee and ligation point three are then described not point-blank, the exercise of trainee does not meet specification, and examinee examines defective.
(3) the utility model can realize trainee or examinee surgery knotting whether meet specification accuracy judge.Whether the utility model employing flexible column can form the measure of blocking to launched infrared ray judges whether knotting meets specification, in fact with flexible column, a branch of very thin light is blocked exactly, once flexible column stressed after will occur little bending, depart from original state slightly, flexible column just hides incessantly infrared ray, even if this just means that two hand forces and ligation point three are near straight line or two hands firmly slightly deviation, also can identify by the utility model.Therefore, sensitivity of the present utility model is very high and have the high advantage of judgment accuracy.
