Knotting is one of operation the most frequently used, the most basic in operation, because hemostasis all needs to carry out ligation with sewing up, and correct ligation depends on the skill level that operator grasps knotting method.The quality of knotting and speed not only affect the length of operating time, the more important thing is the quality of impact operation and the prognosis of patients ' lives.
In surgery knotting teaching, mainly three kinds of correct knotting methods, for singlehanded ropework, both hands ropework with hold pincers ropework.Main Standardization Requirement is as follows:
1, no matter by which kind of method tie a knot, the direction of adjacent two unijunctions must be contrary, otherwise easily break into false knot and loosen.
2, during knotting, two hand forces and ligation point three should, if 3 lines are at a certain angle, easily make ligature come off when firmly straining point-blank.
3, when tightening up toe-in, two hands are firmly wanted evenly, if a hand-tight proficiency pine, then easily become Slipped Clove Hitch and slippage.
4, during deep part knotting, two hands are made to be difficult to simultaneously near ligation place because of narrow space, can to hold one end of line on the other hand after knotting, another line end in the closely place of knotting oppositely passing with the forefinger of an other hand, evenly firmly tightens up and knots.
In traditional operation training, the just simple speed requiring knotting, when examining, employing be also simple count, examine the skill level of knotting with this.Like this, for other code requirements of knotting, the examination do not accomplished, also could not reach the training of Standardization Requirement.Therefore the training and assessment that standardization is carried out in direction, dynamics etc., standard operation requires cannot tied a knot to operator.
Summary of the invention
The present invention is intended to solve the problem, and provides a kind of a kind of surgery standardization knotting training and examination device can implementing standardization such as knotting direction, knotting dynamics etc., standard operation training and assessment to trainee.

Compared with prior art, tool of the present invention has the following advantages:
When using of the present invention, this device is placed in horizontal table top, then by one, knotting exercise line through elastic threads two ends after the ring of the training that is used for tiing a knot, regulates appropriate length, band soft metal rod y direction applies 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 present invention 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 present invention 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 present invention 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 present invention 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 present invention can realize trainee or examinee surgery knotting whether meet specification accuracy judge.The present invention adopts flexible column whether can form the measure of blocking to launched infrared ray to judge 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 present invention.Therefore, sensitivity of the present invention is very high and have the high advantage of judgment accuracy.
