Flattening and cutting tool for needle mounting section of barb thread

Abstract

The utility model discloses a barb thread needle installation section flattening and cutting tool which is characterized by comprising a cutting table, a flattening block located above the cutting table and a cutting blade fixed to the lower portion of one side of the flattening block and driven by an air cylinder, the flattening block drives the cutting blade to do vertical reciprocating motion towards the cutting table top, and the cutting blade is fixed to the cutting table top. During the maximum downward stroke, the cutting blade is in contact with the cutting table top, and the distance between the flattening block and the cutting table top is smaller than or equal to the radius of the suture line. When the suture line is cut in a segmented mode, the head needle containing section of the one-way barb line is flattened, the tail wing welding end is kept round, the flattened needle containing section cannot enter a forming cavity for tail wing welding, and therefore the situation of wrong welding is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of production and manufacturing of medical suture threads, in particular to a tool for flattening and cutting a barbed thread needle segment. Background Art

[0002] Chinese patent CN212191034U discloses a suture thread rotary cutting table, wherein the medical wire pulling device near the output port is a second medical wire pulling device, and the outlet of the second medical wire pulling device is provided with a cutting table for placing the cut suture thread, a second cylinder is provided on the outer wall of the second medical wire pulling device, and a cutting block is provided at the output end of the second cylinder, and the cutting block is provided with a cutting blade facing the cutting table, and the cutting blade is arranged perpendicular to the cutting table, and the second cylinder drives the cutting block to move downward to realize the cutting of the suture thread on the cutting table by the cutting blade.

[0003] Since the barbs formed on the suture line cannot be carried out simultaneously with the welding of the tail and the installation of the suture needle at the other end during the formation of the unidirectional barb line, the barb direction needs to be determined when welding the tail, which leads to low production efficiency and the wrong welding of the head and tail of the suture line due to human factors. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model proposes a barbed wire needle segment flattening and cutting tool to solve the problem of needing to determine the barb direction to avoid welding the wrong wire end when welding the tail.

[0005] A barbed thread needle segment flattening and cutting tool comprises a cutting table, a flattening block located above the cutting table, and a cutting blade fixed to a lower side of the flattening block. Driven by a pneumatic cylinder, the flattening block drives the cutting blade to perform vertical reciprocating motion toward the cutting table surface. When the cutting blade touches the cutting table surface at the maximum downward stroke, the distance between the flattening block and the cutting table surface is less than or equal to the radius of the suture line.

[0006] Furthermore, the cutting blade is fixed to the flattening block through a clamping plate, the clamping plate is provided with a groove matching the blade body of the cutting blade, and screw holes are provided at corresponding positions of the clamping plate and the flattening block, and the cutting blade is clamped by screws.

[0007] Compared with the prior art, the utility model adopts a flattening block and a cutting blade fixed on the lower outer side of the flattening block. While cutting the suture line into segments, the head needle-loading section of the one-way barbed wire is flattened, while the tail wing welding end remains round. The flattened needle-loading section cannot enter the forming cavity of the tail wing welding, so there will be no welding errors. When the needle is finally installed, the flattened part of the needle-loading section can be cut off. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The technical solutions in the embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0012] refer to Figures 1 to 3 As shown, the barbed thread needle segment flattening and cutting tool includes a cutting table 1, a flattening block 2 is provided above the cutting table 1, a clamping plate 5 is provided on the lower right side of the flattening block 2, a groove 4 is provided on the clamping plate 5 to match the blade of the cutting blade 3, and screw holes 6 are provided at corresponding positions of the clamping plate 5 and the flattening block 2, and the cutting blade 3 is fixed to the groove 4 by screws. The cylinder drives the flattening block 2 to drive the cutting blade 3 to move vertically back and forth toward the cutting table 1, and the flattening block 2 and the cutting blade 3 conflict with or disengage from the cutting table 1, so that the cutting blade 3 flattens and cuts the suture thread on the cutting table 1.

[0013] It should be pointed out that the groove 4 can also be set on the lower right side of the flattening block 2.

[0014] The above embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
