Abstract
Description
Technical Field
[0001] This utility model relates to the field of wound dressing manufacturing technology, specifically to a punching machine. Background Technology
[0002] Currently, when medical sponges are used as wound dressings, holes need to be punched inside the sponge to allow for the insertion of drainage tubes and / or irrigation tubes. Commonly used materials for medical sponges include PVA (polyvinyl alcohol) and PU (polyurethane). Polyvinyl alcohol (PVA) medical sponges, as a biodegradable porous medical material, are characterized by their soft texture and high wet strength. In particular, their significant and rapid absorption of exudate makes them widely used in clinical trauma surgery, especially in the field of negative pressure drainage.
[0003] The most traditional way of drilling is by manual drilling. However, manual drilling is very inefficient. Based on this, existing technology uses drilling machines to perform mechanical drilling. However, existing drilling machines also have the following problems: the drilling process is completed mechanically and automatically, but the subsequent pipe threading process still requires manual pipe threading. However, manual pipe threading is inconvenient and inaccurate for operators.
[0004] This solution is developed based on this background. Utility Model Content

The guide tube device, the clamping device, and the punching device are arranged sequentially along the length of the table. The first driving member is used to drive the first clamping member to clamp a sponge. The punching device includes a needle and a second driving member. The second driving member is used to drive the needle to puncture the clamped sponge. The guide tube device includes a second clamping member and a third driving member. The third driving member is used to drive the second clamping member to clamp the guide tube after it passes through the sponge for traction punching.

The first driving member is mounted on the fixing part, and the fixing part has a first through hole corresponding to the output end of the first driving member. The output end of the first driving member passes through the first through hole and is connected to the upper pressure plate.
[0010] Furthermore, the fixing part includes a bottom plate and a top plate disposed opposite to each other, the first through hole is located on the top plate, and the top plate is connected to the bottom plate by at least two connectors.

Detailed Implementation
[0026] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be more thorough and complete.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

Therefore, the exemplary terms “below” and “under” can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.
[0029] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.
[0030] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.
[0031] like Figure 1 , Figure 2 The punching machine shown includes a table 400, on which a clamping device 100, a punching device 200, and a guide tube device 300 are disposed. The guide tube device 300, the clamping device 100, and the punching device 200 are arranged sequentially along the length of the table 400. The clamping device 100 includes a first clamping member 110 and a first driving member 120, the first driving member 120 being used to drive the first clamping member 110 to clamp a sponge. The punching device 200 includes a needle 210 and a second driving member 220, the second driving member 220 being used to drive the needle 210 to puncture the sponge clamped by the clamping device 100. The punching device 200 includes a second clamping member 310 and a third driving member 320, the puncturing end of the needle 210 and the clamping end of the second clamping member 310 both facing the first clamping member 110, the third driving member 320 being used to drive the second clamping member 310 to clamp the guide tube after it passes through the sponge for traction punching.
[0032] like Figure 3 As shown, in some embodiments, the first clamping member 110 includes a fixing part, an upper pressure plate 113, and a lower pressure plate 114. The fixing part is mounted on the table surface 400, and the upper pressure plate 113 and the lower pressure plate 114 are disposed opposite each other within the fixing part. The first driving member 120 is mounted on the fixing part, and the fixing part has a first through hole corresponding to the output end of the first driving member 120. The output end of the first driving member 120 passes through the first through hole and is connected to the upper pressure plate 113. The fixing part can be a frame or other structure. The upper pressure plate 113 and the lower pressure plate 114 are fixed by studs and nuts, making their height adjustable.
[0033] like Figure 3As shown, in some embodiments, the fixing part includes a bottom plate 111 and a top plate 112 disposed opposite to each other, a first through hole is located on the top plate 112, and the top plate 112 is connected to the bottom plate 111 by at least two connectors. The connectors can be columnar structures or plate-like structures, etc., to support the top plate 112.
[0034] Optionally, the first driving member 120 can be a cylinder, hydraulic cylinder or electric push rod, etc., to control the upper pressure plate 113 to move up and down to complete the clamping and releasing operation of the first clamping member 110.
[0035] The space between the upper pressure plate 113 and the lower pressure plate 114 is used to place a sponge. If the pressing force of the upper pressure plate 113 and the lower pressure plate 114 is too small, the fixing effect will be poor, and the sponge will shift during the puncture process of the needle 210. If the pressing force of the upper pressure plate 113 and the lower pressure plate 114 is too large, the sponge will become too tight, increasing the difficulty of puncture. The push cylinder itself does not have the function of controlling the pressing force. In this solution, corresponding protrusions 115 are provided on the upper pressure plate 113 and the lower pressure plate 114. The protrusions 115 are symmetrically arranged with respect to the puncture path of the needle 210. When the upper pressure plate 113 and the lower pressure plate 114 are pressed together, the upper and lower protrusions 115 meet and press the sponge tightly, but the sponge to be punctured between the protrusions 115 is in an unpressed state, fluffy and easy to puncture.
[0036] To improve the puncture effect, a rotating component 230 is provided between the second driving component 220 and the needle 210. The rotating component 230 drives the needle 210 to rotate, and the rotating needle 210 improves the puncture effect during the piercing process. Optionally, the second driving component 220 can be a push cylinder, hydraulic cylinder, electric push rod, or linear module, etc., and the rotating component 230 can be a motor. The output rod of the push cylinder is connected to the base plate, the motor is mounted on the base plate, and the output end of the motor is connected to the needle 210. Figure 4 As shown, the punching device 200 includes a collar 240 and a pin 250. The collar 240 is fitted onto the connecting end of the needle and the output end of the rotating component 230, both of which are set as semi-circular protrusions. The two semi-circular protrusions are staggered and connected. Each semi-circular protrusion has a second through hole. The collar 240 is fitted onto the two semi-circular protrusions. The collar 240 has a third through hole corresponding to the second through hole. One end of the pin 250 is inserted into the third through hole and the second through hole, thereby fixing the needle 210 and the output end of the rotating component 230 together through the pin 250.
[0037] Considering the length and weight of the needle 210 and the motor, it would be unstable to hang both on the output rod of the push cylinder. Therefore, a slide rail is provided on the table 400, and a slide table is slidably connected on the slide rail. The rotating part 230 is fixed to the slide table on the side away from the slide rail.
[0038] Preferably, the third driving component 320 is a pushing cylinder, and the second clamping component 310 is a clamping cylinder. The workflow of this solution is as follows: The sponge is placed on the lower pressure plate 114, and the upper pushing cylinder drives the upper pressure plate 113 to move down and clamp the sponge. The pushing cylinder of the punching device 200 pushes the rotating needle 210 to move horizontally, completely passing through the sponge to achieve piercing. Then, the needle 210 returns and exits the sponge. A guide tube is fitted onto the needle 210, and the horizontal pushing cylinder is activated to make the needle 210 and the guide tube pass through the sponge hole together to the other side. The pushing cylinder of the tube guiding device 300 drives the clamping cylinder to approach the end of the needle 210. Then, the clamping cylinder clamps the guide tube on the needle 210, the needle 210 retracts, the guide tube is clamped by the clamping cylinder and returns, the needle 210 and the guide tube move in opposite directions respectively, and each driving component resets, completing the tube-piercing operation.
[0039] Based on the number of perforations on the sponge, the needle 210 is designed with at least two parallel sets.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
