Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a fiberboard stripping forceps for stripping fiberboard. Background Technology

[0002] Video-assisted thoracoscopic surgery (VATS) has become a standard procedure in thoracic surgery, renowned for its minimal trauma, rapid recovery, and less postoperative pain. Nevertheless, traditional VATS still presents challenges in managing certain complex lesions due to limitations in the field of vision and operating space. This is particularly true for empyema, which requires the removal of the visceral parietal fibrous layer, for which there is currently a lack of surgical instruments specifically designed.

[0003] Since there are currently no suitable surgical instruments for thoracoscopic fiber plasm stripping, other instruments must be used instead. However, since other medical instruments are not specifically designed for fiber plasm stripping, their clamping force is low, which increases the difficulty of the surgery. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a lamina peeling forceps for peeling lamina, which is specifically designed to solve the problem of lamina peeling in specific surgeries. The peeling forceps provided by this utility model, by using a specific surgical tool, significantly improves the precision and safety of the surgery. This peeling forceps can more efficiently peel the visceral parietal lamina, effectively shortening the operation time, while reducing the risk of lung tissue damage and bleeding, thereby significantly reducing surgical risks and the incidence of complications.

[0005] According to a first aspect of the present invention, a fiberboard stripping forceps is provided, comprising: a handle for an operator to hold; a clamping part for clamping a diseased fiberboard and stripping the fiberboard; and a forceps body connected to the handle and the clamping part at its respective ends; the clamping part includes a head and a clamping arm, the clamping arm being connected to the head and the forceps body, the width of the head increasing the further away from the clamping arm; the head includes a first head and a second head, the thickness (d1) of the front end of the first head and the thickness (d2) of the front end of the second head being different.

[0024] First Implementation Method

[0025] according to Figure 1 as well as Figure 2 This utility model provides a fiberboard stripping forceps 100 according to a first embodiment, including a forceps body 10, a forceps handle 20, and a clamping part 30. The forceps body 10 is used to connect the forceps handle 20 and the clamping part 30. The forceps handle 20 is connected to the rear end of the forceps body 10 and is used for gripping by the operator during surgery. It includes a first forceps handle 201 and a second forceps handle 202. The first forceps handle 201 and the second forceps handle 202 are respectively provided with protruding first locking teeth 211 and second locking teeth 212. The inner surfaces of the first locking teeth 211 and the second locking teeth 212 are respectively provided with multiple uneven and mutually cooperating teeth. When the stripping forceps is closed, the first locking teeth 211 and the second locking teeth 212 can overlap vertically. At the same time, the first locking teeth 211 and the second locking teeth 212 can interlock through the teeth on their inner surfaces to lock the first forceps handle 201 and the second forceps handle 202, so as to ensure the stability of the stripping forceps when clamping the fiberboard.

[0026] The clamping part 30 is connected to the front end of the clamp body 10 and is used to clamp and peel off the diseased fiber plate. The clamping part 30 includes a clamp head 300 and a clamp arm 310 connected to the clamp head. Specifically, the clamp head 300 includes a first clamp head 301 and a second clamp head 302, and the clamp arm 310 includes a first clamp arm 311 and a second clamp arm 312. One end of the first clamp arm 311 and the second clamp arm 312 are respectively connected to the first clamp head 301 and the second clamp head 302, and the other end of the first clamp arm 311 and the second clamp arm 312 are connected to the clamp body 10. In use, one of the first clamp arm 311 and the second clamp arm 312 is fixed, while the other is movable. This arrangement allows the fixed clamp arm to provide a stronger clamping force when clamping the diseased fiber plate. Furthermore, the clamp arm 310 is arc-shaped and curved upwards, forming an angle α greater than 90 degrees with the clamp body 10, so as to ensure the operability of the operation in actual surgery while providing a better field of vision and better observation of the fiber plate. Preferably, the included angle α is 160 degrees, which can maintain the best clamping force while maintaining the best field of vision.

[0027] Figure 3(a) is a top view of the head structure of the fiberboard peeling pliers according to the first embodiment of the present invention. Figure 3(b) is a side view of the head structure of the fiberboard peeling pliers according to the first embodiment of the present invention. Further, according to Figure 3(b), the width L1 of the front end of the first plier head 301 and the second plier head 302 is greater than the width L2 of the first plier arm 311 and the second plier arm 312. The width L1 of the first plier head 301 and the second plier head 302 gradually decreases towards the first plier arm 311 and the second plier arm 312, that is, the width of the plier head 300 is larger the further away from the plier arm 310. Further, according to Figure 3(a), the thickness d1 of the front end of the first plier head 301 and the thickness d2 of the front end of the second plier head 302 are different, that is, the front end of one side of the plier head is thinner and formed into a shovel shape for better peeling of the fiberboard, while the front end of the other side of the plier head is thicker than the front end of the plier head on the above side to provide greater clamping force to prevent the fiberboard from falling out of the plier heads on both sides. For example, according to Figure 2 As shown in Figure 3(a), if the thickness of the front end of the first pliers 301 is d1 and the thickness of the front end of the second pliers 302 is d2, then d2 < d1. The above is just an example. In this utility model, d2 can also be greater than d1. No special limitation is made here.

[0028] Figure 4 A schematic diagram of the clamping part 30 according to the first embodiment of this utility model.

[0029] according to Figure 4In the first embodiment provided by this utility model, both the first clamp head 301 and the second clamp head 302 are configured as hollow triangles, that is, the center of the first clamp head 301 and the second clamp head 302 includes a window portion 320. The purpose of providing the window portion 320 is to better observe the fiberboard covered by the clamp head, so as to avoid clamping the non-lesioned fiberboard tissue that does not need to be peeled. Furthermore, the opposing inner surfaces of the first clamp head 301 and the second clamp head 302 are rough surfaces to increase friction and provide greater clamping force.

[0030] Second Implementation Method

[0031] The second embodiment of this utility model will be described below. In the second embodiment, except for the different arrangement of the pliers head, the arrangement of other structures is the same as that in the first embodiment.

[0032] Figure 5 This is a schematic diagram of the clamping part 30 according to the second embodiment of the present invention.

[0033] according to Figure 5 In the second embodiment, the first jaw 301 and the second jaw 302 are configured in a claw shape. Compared with the jaw structure of the first embodiment, the width L1 of the jaw in the second embodiment is smaller, thus enabling it to grip smaller areas of fiberboard, i.e., it can be used for fine processing. Furthermore, the inner surface of the jaws is provided with a corrugated structure with concave and convex parts, i.e., multiple recesses 350 and multiple protrusions 340. The multiple recesses 350 and multiple protrusions 340 on the inner surface of the first jaw 301 correspond one-to-one with the multiple protrusions 340 and multiple recesses 350 on the inner surface of the second jaw 301. With this arrangement, when the peeling jaws are closed, the inner surfaces of the first jaw 301 and the second jaw 302 can be completely engaged.

[0034] Specifically, Figure 5 The diagram shows the engaged state of the first jaw 301 and the second jaw 302 when the clamping part 30 is closed. According to... Figure 5 When the clamping part 30 is closed, the multiple recesses 350 and protrusions 340 on the inner surfaces of the two clamp heads can engage with each other to provide greater friction, thereby improving the precision of the surgery and providing greater clamping force.

[0035] The foregoing details the forceps head structures of the first and second embodiments of this invention. According to this invention, greater clamping force and dissection efficiency are provided, significantly reducing surgical difficulty. The arc-shaped design of the forceps arm 310 facilitates intraoperative observation and reduces the risk of misoperation. The window portion 320 of the forceps head in the first embodiment increases the clamping force while also facilitating intraoperative observation. The claw-shaped forceps head and the interlocking concave-convex structure on the inner surface of the forceps head in the second embodiment further enhance clamping force and operational precision, making it suitable for delicate surgeries. This invention can effectively shorten surgical time, reduce the risk of lung tissue damage and bleeding, and improve surgical safety.

[0036] The above content represents only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
