The processed suture thread is wound by a winding drum on the winding mechanism 101, and the winding drum is driven by a winding motor. Because pay off mechanism, admission machine construct common structure, do not do the repeated description.
Wherein the cutter can adopt the ultrasonic wave sword, of course, also can adopt ordinary cutter under the circumstances of guaranteeing the incision is sharp, and the ultrasonic wave sword does not do the requirement to relative feed dynamics alone to incision quality is higher.
During operation, the first clamping unit 1 and the second clamping unit 2 clamp a section of suture line, the tension of the section of suture line is kept, then the line pressing balance wheel 5 is driven by the corresponding motor to swing for a certain angle, the suture line is pressed towards the cut of the cutter, meanwhile, vibration of the processed part of the suture line is eliminated, and accurate cutting is achieved. Preferably, the sides of the roller balance 5 that are in contact with the suture may be provided with a damping layer, which has the effect of further damping and fixing the position of the cutting point.
The sliding support 4 is further provided with a first thread passing wheel set 41 and a second thread passing wheel set 42 which are positioned on two sides of the thread pressing balance wheel, the first thread passing wheel set and the second thread passing wheel set are respectively provided with two idler wheels, and the suture thread is in contact with the thread pressing balance wheel after being adjusted in posture through the first thread passing wheel set and the second thread passing wheel set, namely, a more stable suture thread section which is beneficial to processing is formed between the first clamping unit and the second clamping unit.
In order to realize the cutting with different circumferential azimuth angles, the first clamping unit 1 and the second clamping unit 2 are respectively provided with a clamping frame 121, a rotating shaft 122, a turnover frame 123, a linear driving mechanism 124, a rotary driving mechanism 125, a fixed clamping piece 126 and a movable clamping piece 127, the turnover frame is rotatably arranged on the clamping frame through the rotating shaft, and the rotary driving mechanism is arranged on the clamping frame and is in driving connection with the rotating shaft; the fixed clamping pieces are fixedly connected to the turnover frame, and the movable clamping pieces are arranged on the turnover frame in a way of being capable of moving linearly in opposite directions or back to the fixed clamping pieces under the driving connection of the linear driving mechanism; the fixed jaw 126, the movable jaw 127, the roll-over stand, and the linear driving mechanism form the first clamping portion (second clamping portion).
The suture line passing through the first clamping unit and the second clamping unit is attached to the surface of the fixed clamping piece, when the respective movable clamping piece presses the surface of the fixed clamping piece, a section of suture line keeping tension is formed between the first clamping unit and the second clamping unit, when the turnover frame 123 rotates synchronously, the section of suture line clamped rotates, so that different directions of the circumference of the suture line are opposite to the cutter, the suture line is pressed down by the pressing balance wheel again, and barb structures are formed on different direction angles of the circumference of the suture line.
In the above embodiment, in order to avoid positioning errors and avoid deformation of the suture line which cannot be recovered in a short time due to 'point compression', the suture line is clamped in a planar manner by using the movable clamping piece and the fixed clamping piece, and because the movable clamping piece and the fixed clamping piece have a certain length in the longitudinal direction of the suture line, the corresponding static friction force can keep longitudinal tension, but in the overturning process, if the tension loaded on the outer sides of the first clamping unit and the second clamping unit still exists, when the overturning frame rotates, the suture line between the first clamping unit and the second clamping unit possibly slides relative to the fixed clamping piece in the circumferential direction, so that the suture line does not rotate along with the overturning of the overturning frame, and the circumferential azimuth angle of cutting cannot be adjusted.
Aiming at the possible defects, the embodiment is further optimized as follows, a hole groove opposite to the fixed clip is arranged at two side parts of the movable clip 127 in a penetrating way, an iron sheet 128 with one side edge capable of extending out of the hole groove towards the fixed clip is arranged in the hole groove, and an electromagnet 129 opposite to the iron sheet is further arranged at the side part of the movable clip. In the initial state, the movable clamping piece is positioned above the fixed clamping piece, the lower end of the iron piece naturally exposes out of the hole groove, the electromagnet is electrified in the process that the movable clamping piece 127 moves towards the fixed clamping piece, so that the iron piece is tightly attached to the groove wall of the hole groove under the action of magnetic force to form stronger static friction force, before the lower side surface of the movable clamping piece 127 is completely attached to the side surface of the fixed clamping piece, the lower edge of the iron piece firstly presses a suture line, at the moment, the tension mechanisms on the outer sides of the first clamping unit and the second clamping unit are loosened, and particularly, a tension wheel in the pay-off mechanism reversely swings against elastic force to eliminate tension; the take-up mechanism of the take-up mechanism stops the pull force of the take-up; therefore, tension is kept between the first clamping unit and the second clamping unit, and then when the movable clamping piece 127 is completely pressed to the fixed clamping piece, the ferromagnetic iron is powered off, the suction force to the iron piece is eliminated, and the point type pressing to the suture line along the lower edge of the iron piece is also eliminated; when the turnover frames of the first clamping unit and the second clamping unit are turned over randomly, the turning state of the corresponding suture line cannot be damaged due to circumferential sliding, and the subsequent processing quality is ensured.
In order to make iron piece structure have better instantaneous oppression effect, pressure is enough when oppressing the stylolite along under the iron piece promptly, but during the electro-magnet outage, the pressure that the stylolite was loaded to the iron piece can be removed fast, has made following optimization to the embodiment again: the hole groove is a flat hole matched with the iron sheet, one side wall of the hole groove close to the electromagnet is a vertical wall, the other side wall of the hole groove is an inclined wall, and when the electromagnet is electrified to attract the iron sheet, static friction force is formed between the iron magnet and the vertical wall; when the electromagnet is powered off, the iron sheet is laterally attached to the inclined wall. Under the electro-magnet actuation state, the iron piece keeps vertical state, and forward acts on the stylolite, can not interfere the laminating action between activity clamping piece and the fixed clamping piece, and when removing magnetic force, the iron piece is easily toppled over towards the direction of electro-magnet dorsad to its oppression power of loading the stylolite is removed in the twinkling of an eye, does not have remaining probably to lead to the stylolite because the effort of "point type" oppression and deformation.
Further, in order to enhance the above effect, the vertical wall has a plurality of minute protrusions for enhancing static friction force, and the inclined wall is a smooth surface; correspondingly, the side that iron piece and vertical wall are relative has a plurality of small bellyings, the iron piece with the side that the skew wall is relative is the smooth surface.
The middle part of the fixed clamping piece 126 or the movable clamping piece 127 is provided with a pressure-sensitive element for collecting pressure signals, the pressure-sensitive element adopts a pressure-sensitive resistor for detecting the pressure signals, and when the pressure loaded on the pressure-sensitive resistor changes, the resistance value of the pressure-sensitive resistor is changed in a relevant way. When the movable clamping piece completely presses the fixed clamping piece, the pressure-sensitive element detects the pressure change, the electromagnet is powered off immediately, and the time for pressing the suture line by the iron piece is shortened as much as possible.
The first clamping unit 1 can be arranged on one side of the sliding support in a linear sliding manner towards or away from the second clamping unit 2, in the embodiment, the first clamping unit 1 is arranged on the other rail in a sliding manner, so that the tension of the suture thread between the first clamping unit and the second clamping unit can be adjusted. Since the tension of the suture may affect the quality of the incision, for example, the suture may not maintain a completely straight state in a relaxed state of the suture, the position of the tangent point may be changed, and the suture may be cut, and may also cause the incision depth of the suture to be inconsistent, when the tension of the suture to be processed is insufficient, the position of the first clamping unit may be appropriately adjusted, thereby ensuring the tension of the suture to be in a desired state.
A cutter sleeve 7 is fixedly arranged at the lower part of the sliding support 4, and the cutter 6 is provided with a cutter handle 62 and a blade 61 positioned at one end of the cutter handle; the knife handle is inserted in the knife sleeve. There is certain inclination between the incision of cutter and the stylolite, and after accomplishing forward barb processing, the incision inclination of cutter can be adjusted, cuts again and forms reverse barb, and this kind of adjustment can utilize gear drive driven mode to realize automatically, but because the diameter of stylolite is only 0.5 millimeter, and direct drive handle of a knife pivoted mode has the stack of various errors, probably influences the incision quality.
As shown, the end of the tool shank 62 has a positioning column 63 extending out of the end of the tool sleeve, the end of the tool sleeve has a plurality of longitudinally extending insertion holes 71, and a locking plate 8 has a slip 81 opposite to the insertion holes and is inserted in the insertion holes via the slip, so that the locking plate 8 can move linearly relative to the tool sleeve; the side face, opposite to the tail end of the tool handle, of the locking plate is provided with two positioning holes 82; after the inserting strip is partially pulled out of the inserting hole, the cutter handle is rotated relative to the cutter sleeve to enable the positioning column to be opposite to one positioning hole, and then when the inserting strip is completely inserted into the inserting hole, the positioning column is locked in the positioning hole. Because the fixed setting of cutter sleeve is fixed to be set up on the sliding support, utilize lockplate to carry out accurate switching with the cutter between two processing inclination, the cutter is higher for the telescopic inclination control precision of cutter.
The line pressing balance wheel and swing rod 9 is connected to the sliding support, the middle of the swing rod is rotatably arranged on the sliding support, the line pressing balance wheel is arranged at one end of the swing rod, the other end of the swing rod is provided with a reverse balance wheel 91, and the reverse balance wheel and the line pressing balance wheel are symmetrical about the rotation center of the swing rod.
