Description

Technical Field

[0001] The utility model relates to suture processing equipment, in particular to a synchronous cutting and rotating device for multiple multi-angle equipment of barbed sutures. Background Art

[0002] Surgical sutures are commonly used surgical consumables. In order to make surgical sutures firmly fixed, effectively prevent tissue sliding and avoid falling off, sutures with barbed structures are generally used. Compared with traditional sutures, barbed sutures can not only maintain appropriate tension and prevent tissue sliding, but also save a lot of surgical time and surgical costs. In addition, the use of barbed sutures reduces the complications associated with traditional sutures, such as knot falling off, thread displacement or infection, and even incision dehiscence.

[0003] Existing suture processing equipment, such as CN202220291728.4, has a high degree of automation, and the depth, shape, and spacing of the barbs can be flexibly adjusted. It can realize the processing of double-angle barbed sutures and multiple sutures, and can meet the processing needs of surgical sutures with special structures. However, the equipment can only process one suture at a time, which seriously limits the processing efficiency of the sutures. However, if the number of corresponding mechanisms is simply increased to multiple on the basis of the above-mentioned equipment, the equipment will be larger and the difficulty of synchronous cutting and processing of sutures will be greatly increased. Therefore, there is an urgent need for a device that can synchronously drive multiple sutures to rotate and move synchronously and is smaller in size. Utility Model Content

[0004] The purpose of the utility model is to provide a device for synchronously cutting and rotating multiple barbed sutures at multiple angles, so as to solve the problem that the existing suture processing equipment cannot synchronously drive multiple sutures to rotate and move synchronously.

[0005] The utility model is implemented as follows: a synchronous cutting rotation device for multiple multi-angle devices of barbed sutures, comprising a multi-axis wire pressing rotation device and a multi-axis clamping rotation device, wherein the multi-axis wire pressing rotation device and the multi-axis clamping rotation device are located on the same straight line; the multi-axis wire pressing rotation device comprises a first mounting frame and a plurality of rotating shafts arranged side by side, the rotating shafts are rotatably connected to the first mounting frame, and the plurality of rotating shafts are driven to rotate synchronously by a first driving element, a central hole for threading sutures is opened at the axis of the rotating shaft, and a roller group for clamping sutures is arranged at the end of the rotating shaft; the multi-axis clamping rotation device comprises a second mounting frame and a plurality of wire pulling jaws arranged side by side, the wire pulling jaws are used to clamp sutures, the wire pulling jaws are rotatably connected to the second mounting frame, and the wire pulling jaws are driven to rotate synchronously by a second driving element.

[0006] A rotating body rotating together with the rotating shaft is arranged at the end of the rotating shaft, a pressure cover is hinged on the rotating body, and rollers are respectively arranged on the rotating body and the pressure cover.

[0007] The wire pulling clamp includes a rotating connecting rod, a clamping rod is inserted in the rotating connecting rod, two clamping chucks arranged opposite to each other are hinged at the end of the rotating connecting rod, two connecting rods are hinged at one end of the clamping rod, the two connecting rods are hinged to the two clamping chucks respectively, and a third driving element is rotatably connected to the other end of the clamping rod, and the third driving element drives the clamping rod to extend and retract to clamp or open the two clamping chucks.

[0008] A guide frame is arranged between the third driving element and the clamping claw pull rod, and the guide frame is arranged on the second bracket. A plurality of sliding rods are connected to the guide frame. One end of the sliding rod is connected to the third driving element, and the other end is installed with a bearing. The end of the clamping claw pull rod is connected to the sliding rod through the bearing.

[0009] A synchronous pulley is arranged on the rotating shaft / the wire-pulling clamp, and the first driving element / the second driving element is simultaneously connected to the synchronous pulleys on a plurality of rotating shafts / the wire-pulling clamps through a synchronous belt.

[0010] It also includes a traction device arranged on the frame, and the second mounting frame is driven by the traction device to move along the straight line where the multi-axis pressing rotation device and the multi-axis clamping rotation device are located.

[0011] The traction device is a linear module, and the second mounting frame is fixed on a slide table of the linear module.

[0012] In the utility model, multiple sutures first pass through the multi-axis pressing rotation device, and then enter the multi-axis clamping rotation device, and are clamped by the multi-axis clamping rotation device. The multi-axis pressing rotation device and the multi-axis clamping rotation device cooperate with each other to drive the multiple sutures to rotate synchronously, and the traction device can drive the multiple sutures to move synchronously. Since the utility model realizes the synchronous rotation and movement of multiple sutures, it is convenient to cut and process multiple sutures simultaneously through the cutting device, thereby realizing the function of processing multiple sutures simultaneously with one device.

[0013] In the utility model, a plurality of rotating shafts arranged side by side are synchronously driven by a driving element, and a plurality of wire pulling clamps arranged side by side are also synchronously driven by a driving element, so it is only necessary to ensure the synchronization of the two driving elements to ensure the synchronization of the rotation of all sutures.

DETAILED DESCRIPTION

[0021] The structure of the utility model is further described below in conjunction with the accompanying drawings.

[0022] like Figure 1 , Figure 2As shown, it is a multi-suture processing and cutting device, including a frame 1, a feeding device 2, a multi-axis pressing and rotating device 3, a multi-wire cutting table 4, a cutting device 7, a multi-axis clamping and rotating device 5, and a traction device 6. The feeding device 2 outputs multiple sutures at the same time, and the sutures pass through the multi-axis pressing and rotating device 3, the multi-wire cutting table 4, and the multi-axis clamping and rotating device 5 in sequence. The multi-axis pressing and rotating device 3 and the multi-axis clamping and rotating device 5 cooperate with each other to drive the multiple sutures to rotate synchronously, and the traction device 6 drives the multiple sutures to move synchronously. In the process of the rotation and movement of the sutures, the cutting device 7 simultaneously cuts the multiple sutures, thereby realizing the function of processing multiple sutures simultaneously with one device.

[0023] The synchronous rotation driving device of the utility model comprises a multi-axis wire pressing rotation device 3 and a multi-axis clamping rotation device 5. The multi-axis wire pressing rotation device 3 and the multi-axis clamping rotation device 5 are located on the same straight line.

[0024] like Figure 3 , Figure 4 As shown, the multi-axis pressing thread rotating device 3 is arranged on the frame 1, including several rotating shafts 3-1 arranged side by side, a center hole is opened at the axis of the rotating shaft 3-1, the rotating shaft 3-1 is installed on the first bracket, and the rotating shaft 3-1 can rotate freely on the first bracket, and multiple sutures from the feeding device 2 pass through different center holes of the rotating shaft 3-1 respectively, and a group of rollers 3-7 for clamping the sutures are arranged at the end of the rotating shaft 3-1, and the first driving element 3-3 drives several rotating shafts 3-1 to rotate synchronously to drive multiple sutures to rotate synchronously around their own axes. The sutures are clamped by two rollers 3-7, so that when the rotating shaft 3-1 rotates, the sutures can be driven to rotate together. At the same time, since the rollers 3-7 can rotate around their own axis, the movement of the sutures along their own length direction will not be restricted.

[0025] In order to make multiple rotating shafts 3-1 rotate synchronously, a synchronous pulley 3-4 is arranged on each rotating shaft 3-1, and a driving wheel is arranged on the rotating shaft of the first driving element 3-3, so that all rotating shafts 3-1 are driven to rotate synchronously through the synchronous belt. In order to ensure the meshing of the synchronous belt and the synchronous pulley 3-4, a belt pressing shaft 3-5 is also arranged on the frame 1, and the belt pressing shaft 3-5 is located above the gap between two adjacent rotating shafts 3-1.

[0026] A rotating body 3-2 is provided at the end of the rotating shaft 3-1 and rotates together with the rotating shaft 3-1. A pressure cover 3-6 is hinged on the rotating body 3-2. The suture thread is inserted between the rotating body 3-2 and the pressure cover 3-6. Rollers 3-7 are provided on the rotating body 3-2 and the pressure cover 3-6 respectively. The suture thread is clamped by the above two rollers 3-7.

[0027] The pressing force of the two rollers 3-7 on the suture thread can be adjusted by adjusting the angle of the pressure cover 3-6. An elastic member such as a spring can be provided between the pressure cover 3-6 and the rotating body 3-2. The elastic member is located at one end of the principle roller 3-7. An adjusting pin 3-8 can also be inserted into the rotating body 3-2. The extension length of the adjusting pin 3-8 can be adjusted by rotating it, thereby adjusting the swing angle of the pressure cover 3-6.

[0028] The first driving element 3 - 3 is a motor.

[0029] The multi-wire cutting table 4 is arranged between the multi-axis wire pressing rotating device 3 and the multi-axis rotating traction device 6, and is used to synchronously clamp multiple suture threads to facilitate cutting by the cutting device 7.

[0030] like Figure 5 , Figure 6 As shown, the multi-axis clamping and rotating device 5 is arranged on the traction device 6 through the second bracket, and is driven by the traction device 6 to move along a straight line. The multi-axis clamping and rotating device 5 includes a plurality of wire pulling claws arranged side by side, and the wire pulling claws are rotatably connected to the second bracket. The wire pulling claws are used to clamp the suture thread, and the second driving element drives the plurality of wire pulling claws to rotate synchronously to cooperate with the multi-axis wire pressing rotating device 3 to drive the plurality of suture threads to rotate synchronously around their own axes.

[0031] The structure of the second driving element driving the wire pulling clamps to rotate synchronously is basically the same as the structure of the first driving element 3-3 driving the rotating shaft 3-1 to rotate synchronously, and is also transmitted through a synchronous belt mechanism to achieve synchronous rotation of multiple wire pulling clamps.

[0032] The wire pulling clamp includes a rotating connecting rod 5-1, a clamping rod 5-2 is inserted into the rotating connecting rod 5-1, two clamping chucks 5-3 arranged opposite to each other are hinged at the end of the rotating connecting rod 5-1, two connecting rods 5-4 are hinged at one end of the clamping rod 5-2, the two connecting rods 5-4 are respectively hinged to the two clamping chucks 5-3, and a third driving element 5-5 is rotatably connected to the other end of the clamping rod 5-2, and the third driving element 5-5 drives the clamping rod 5-2 to extend and retract so that the two clamping chucks 5-3 are clamped or opened.

[0033] The rotating connecting rod 5-1 is installed on the frame 1, and the rotating connecting rod 5-1 can rotate freely. A synchronous pulley 3-4 is arranged on the rotating connecting rod 5-1, and a driving wheel is arranged on the rotating shaft of the second driving element. All the rotating connecting rods 5-1 are driven to rotate synchronously through the synchronous belt.

[0034] The end of the clamping rod 5-2 is connected to the clamping chuck 5-3, so the clamping rod 5-2 will rotate along with the rotating connecting rod 5-1. Since the clamping rod 5-2 needs to rotate and move along its own axial direction, the clamping rod 5-2 and the third driving element 5-5 need to be rotatably connected.

[0035] A guide frame 5-6 is arranged between the third driving element 5-5 and the clamping claw pull rod 5-2. The guide frame is fixed on the second bracket. A plurality of sliding rods 5-7 are connected to the guide frame 5-6. The sliding rods 5-7 can move freely along their own length direction. One end of the sliding rod 5-7 is connected to the third driving element 5-5, and the other end is installed with a bearing 5-8. The end of the clamping claw pull rod 5-2 is connected to the sliding rod 5-7 through the bearing 5-8.

[0036] The third driving member can be a cylinder. When the third driving member is extended or retracted, it drives the slide rod 5-7 to move forward and backward. Since the end of the clamping claw pull rod 5-2 is connected to the slide rod 5-7 through the bearing 5-8, the slide rod 5-7 drives the clamping claw pull rod 5-2 to move forward and backward without affecting the rotation of the clamping claw pull rod 5-2.

[0037] The feeding device 2 is arranged on the frame 1 and is used to supply a plurality of suture threads simultaneously. The feeding device 2 comprises a plurality of spools 2-1, a thread passing mechanism 2-2 and a thread feeding mechanism 2-3.

[0038] The bobbin 2 - 1 is used to output suture threads. The number of bobbin 2 - 1 is determined according to needs, and multiple bobbin 2 - 1 output multiple suture threads simultaneously.

[0039] The output sutures first pass through the wire-passing mechanism 2-2. The wire-passing mechanism 2-2 is used to guide multiple sutures. During the guiding process, multiple sutures are made parallel to each other, so that they can enter the wire feeding mechanism 2-3 later. It is also used for the corner position of the sutures, so that the sutures can turn after passing through the wire-passing mechanism 2-2, which can reduce the overall length of the device. The wire-passing mechanism 2-2 includes at least one set of wire-passing wheels. The number of wire-passing wheels is determined according to the number of sutures. Multiple wire-passing wheels are located in the same plane. After the sutures pass through the wire-passing wheels, they are transported forward in the same plane. When the wire-passing wheels are located in a horizontal plane, the sutures after passing through the wire-passing mechanism 2-2 are located in the same horizontal plane.

[0040] The suture thread passing through the wire passing mechanism 2-2 enters into the wire feeding mechanism 2-3, which includes a group of parallel pressure rollers, two of which are horizontal and arranged up and down, and the suture thread passes between the two pressure rollers. The distance between the two pressure rollers is adjustable, and the suture thread is pressed by the two pressure rollers and driven to move forward synchronously by the rotation of the pressure rollers.

[0041] As a further improvement of the multi-line multi-angle barbed suture processing and cutting equipment of the utility model, it also includes a tension adjustment device 10, which is located between the wire feeding mechanism 2-3 and the multi-axis wire pressing and rotating device 3, and is used to adjust the tension of the suture.

[0042] A plurality of sutures are synchronously cut by a cutting mechanism on a multi-wire cutting table 4, and a cutting device 7 is arranged on one side of the multi-wire cutting table 4. The cutting device 7 comprises a three-axis slide 7-1, on which a horizontal rotating tool holder 7-2 is arranged, the rotating tool holder 7-2 is driven to rotate by a motor, and a blade 7-3 is arranged on the rotating tool holder 7-2, and the blade 7-3 is driven to move by the three-axis slide 7-1 to realize the cutting action, thereby cutting out the required barb mechanism on the suture.

[0043] The traction device 6 is arranged on the frame 1, and is used to drive the movement of the multi-axis clamping and rotating device 5. The traction device 6 can be a linear module. The multi-axis clamping and rotating device 5 is fixed on the slide of the linear module. The linear module drives the multi-axis clamping and rotating device 5 to reciprocate in a linear direction.

[0044] The multiple suture processing and cutting equipment of the utility model also includes a cutting device 8 and an auxiliary wire clamping device 9, which are located between the multi-wire cutting table 4 and the multi-axis clamping and rotating device 5, and are used to achieve synchronous cutting of the processed multiple sutures. The auxiliary wire clamping device 9 is required to clamp the sutures during the cutting process.

[0045] The feeding device 2 synchronously conveys multiple sutures, and the multiple sutures are synchronously rotated by the multi-axis pressing rotating device 3 of the utility model in cooperation with the multi-axis clamping rotating device 5, and the multiple sutures are synchronously advanced by the multi-axis clamping rotating device 5. The multiple sutures are synchronously rotated and moved on the multi-wire cutting table 4, and the synchronous processing of the barbed structures of the multiple sutures can be achieved by a blade of the cutting device 7. The utility model also carries out an integrated design, so that the structure of each part of the device is minimized as much as possible, so that the volume of the whole device of the utility model is small.
