Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a titanium clamp with status indication function. Background Technology

[0002] During medical surgery, to avoid increasing the difficulty of the operation due to excessive bleeding or ruptured blood vessels in the target organ, the blood vessels connected to the target organ are usually ligated and hemostatically stopped first using titanium clips. The instrument used is a titanium clip. The titanium clip works by first inserting the titanium clip into the human body, then encircling the blood vessel with titanium clips, and applying external force to make the titanium clips clamp tightly to achieve the hemostatic effect.

[0003] Existing titanium clips, such as the Chinese utility model patent with authorization number CN 221154231 U, disclose a double-sided counting mechanism for disposable continuous-fire titanium clips. By setting a window on the handle, the operator can observe the numbers on the internal counting mechanism, allowing for a clear understanding of the number of titanium clips and serving as a reminder of the clip quantity. However, the operator still needs to judge the working status of the titanium clips themselves. The titanium clips themselves are pre-loaded with some titanium clips and have two states during operation: clip feeding and firing. These two states share the same movable handle, and it is difficult to quickly distinguish the current state from the outside. In the highly stressful surgical process, this can easily confuse the surgeon about the current working status of the titanium clips, making it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a titanium clip with a status indication function. By adding a viewing window to the handle and optimizing the transmission structure inside the handle that is associated with feeding and firing, the current status of the titanium clip can be clearly identified through the viewing window, whether it is feeding or firing, making it convenient for operators to use.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] A titanium pliers with status indication function includes a pliers head, a pliers body, and a firing mechanism. The firing mechanism includes a fixed handle and a movable handle hinged to the fixed handle. The upper part of the fixed handle is slidably provided with a first transmission seat and a second transmission seat in a horizontal direction. The first and second transmission seats are both tractively connected to the movable handle and the pliers body and are adapted to reciprocate under the drive of the movable handle to perform nail feeding and firing. The fixed handle has a nail feeding window and a firing window. The second transmission seat has a color mark, which is adapted to be displayed through the nail feeding window and the firing window respectively when the titanium pliers are in the nail feeding and firing states.

[0007] Furthermore, the second transmission seat includes a transmission body and a cover plate fixedly installed on the top of the transmission body. The color mark is provided on the top surface of the cover plate, and the nail feeding window and firing window are opened on the top of the fixed handle.

[0008] Furthermore, the nail feeding window and the firing window are located at the end of the fixed handle away from the pliers head, and the color mark is located at the end of the cover plate away from the pliers head.

[0009] Furthermore, the transmission body has symmetrical connecting plates on both sides of its proximal end, and the proximal ends of the two connecting plates are connected to an integrally formed support column. An integrally formed limiting block is provided on the inner top side. The bottom of the proximal end of the cover plate has a limiting plate that abuts against the support column, and the distal end has a limiting part that extends to both sides. The two sides have limiting grooves that are adapted to the limiting blocks. The limiting part overlaps the distal end of the corresponding connecting plate, and the limiting block is engaged in the limiting groove from bottom to top.

[0010] Furthermore, the limiting plate is provided in two symmetrical positions on both sides of the cover plate, and the bottom is provided with an arc-shaped groove that matches the outer circumferential surface of the support column.

[0011] Furthermore, the cover plate has slopes on both sides that are inclined toward the center of the cover plate, and the top surface of the limiting block is a downward inclined surface.

[0012] Furthermore, a spring is provided between the first transmission seat and the second transmission seat, a connecting post is provided at the near end of the first transmission seat, and the two ends of the spring are respectively fastened to the connecting post and the support post. A clearance groove with an arc-shaped cross section is provided at the center of the bottom surface of the cover plate corresponding to the spring.

[0013] Furthermore, the fixed handle includes a first handle seat and a second handle seat that interlock with each other. The feeding window and the firing window have the same structure, both made of transparent material and having a rectangular window body. The two sides of the window body are provided with strip-shaped grooves. The interlocking surfaces of the first handle seat and the second handle seat are respectively provided with notches, forming a rectangular through groove adapted to the window body. The two sides of the through groove near the bottom of the notch are provided with protrusions adapted to the strip-shaped grooves. The window body slides into the strip-shaped grooves through the protrusions and is fixedly connected to the fixed handle.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] (1) This utility model sets two viewing windows on the handle and sets corresponding color marks on the second transmission seat associated with the nail feeding and firing movements. Through the reciprocating motion of the second transmission seat, the color marks are moved to the corresponding nail feeding and firing windows, so as to clearly identify whether the current state of the titanium clamp is nail feeding or firing, which is convenient for operators to use.

[0016] (2) The second transmission seat of this utility model provides a position for the color mark by setting a cover plate, so that the color mark is facing the top of the fixed handle, and the corresponding window is also set on the top of the fixed handle for easy observation during operation.

[0017] (3) By setting the color mark and the viewing window at the end of the cover plate and the fixed handle respectively, this utility model can minimize the height difference between the viewing window and the color mark according to the existing shape of the movable handle, prevent the tilted line of sight from seeing the non-color mark through the window, and make the color mark completely cover the window's line of sight. Accordingly, when the size of the color mark is fixed, the window can be maximized, making it easier for the operator to observe.

[0018] (4) This utility model achieves the limitation of the cover plate moving downward and to the near end by the cooperation of the limiting part and the far end of the connecting plate and the cooperation of the limiting plate and the support column. At the same time, the limitation of the cover plate moving to both ends and upward is achieved by the cooperation of the limiting block and the limiting groove, thereby realizing the installation of the cover plate and the transmission body. The structure is simple and the installation efficiency is improved.

[0019] (5) By setting an arc groove at the bottom of the limiting plate, the limiting plate and the top and left and right sides of the support column are all limited. During installation, the support column can be used as the installation base point, which is convenient for assembly. At the same time, the overall structure is more stable after installation.

[0020] (6) The present invention facilitates the insertion of the limiting block into the limiting groove by the combination of the inclined surface and the slope.

[0021] (7) This utility model avoids interference with the extension and contraction of the spring by setting an avoidance groove at the bottom of the cover plate, thus affecting the operation feel of the titanium clamp and ensuring that the performance remains unchanged.

[0022] (8) This utility model achieves the synchronous installation of two windows when the two handle seats of the fixed handle are fastened together by the cooperation of the boss and the strip groove. The structure is simple, easy to assemble, and the installation is firm. Attached Figure Description

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] (Example 1)

[0033] like Figures 1 to 5 The titanium pliers shown have a status indication function, including a plier head 1, a plier body 2, and a firing part 3. The firing part 3 includes a fixed handle 3-1 and a movable handle 3-2 hinged to the fixed handle 3-1. The upper part of the fixed handle 3-1 is slidably provided with a first transmission seat 4 and a second transmission seat 5 in a horizontal direction. The first transmission seat 4 and the second transmission seat 5 are both connected to the movable handle 3-2 and the plier body 2, so that they reciprocate under the drive of the movable handle to feed nails and fire. The fixed handle 3-1 has a nail feeding window 6 and a firing window 7. The second transmission seat 5 has a color mark 8. The movement of the second transmission seat 5 drives the color mark 8 to move, so that when the titanium pliers are in the nail feeding and firing states, the colors are displayed through the nail feeding window and the firing window, respectively.

[0034] The movement of the two transmission seats driven by the movable handle 3-2 is prior art in this field. Referring to titanium pliers disclosed in patent publications CN221154231U, CN221750818U, and CN204364072U, a brief description is provided here for ease of understanding in subsequent workflows. The hinge joint between the movable handle 3-2 and the fixed handle 3-1 forms a rotating part. A connecting part extending away from the rotating part is provided at the top. A first connecting rod 9 and a second connecting rod 10 are hinged to the connecting part in a staggered manner. The first connecting rod 9 and the second connecting rod 10 are V-shaped, and their other ends are respectively hinged to the first transmission seat 4 and the second transmission seat 5. The first transmission seat 4 and the second transmission seat 5 are respectively connected to the pliers body for transmission. This allows for lightly gripping the movable handle 3-2 to feed the nail, the second transmission seat 5 to move to the left and stop, and then firmly gripping the movable handle 3-2 to fire, at which point the second transmission seat 5 returns to its original position.

[0035] Specifically, for ease of observation, the nail feeding window 6 and the firing window 7 are located at the top of the fixed handle 3-1, arranged from right to left according to the movement trajectory of the second transmission seat 5. The second transmission seat 5 includes a transmission body 5-1 and a cover plate 5-2, with a color mark 8 located on the top surface of the cover plate 5-2, below the two windows. Considering that in the original titanium clamp design, the height difference between the proximal end of the second transmission seat 5 and the top of the fixed handle 3-1 is minimal, the color mark 8 is positioned at the end of the cover plate 5-2 furthest from the clamp head 1. Correspondingly, the nail feeding window 6 and the firing window 7 are located at the end of the fixed handle 3-1 furthest from the clamp head. By minimizing the height difference between the viewing window and the color mark, and preventing tilted eyes from seeing non-color mark areas through the window, the color mark can completely cover the window's field of vision. Consequently, with a fixed color mark size, the window can be maximized, facilitating operator observation.

[0036] The fixed handle 3-1 includes a first handle seat and a second handle seat that interlock with each other. The nail feeding window 6 and the firing window 7 have the same structure, both made of transparent material and having a rectangular window body. The two sides of the window body are provided with strip grooves 6-1. The interlocking surfaces of the first handle seat and the second handle seat are respectively provided with notches, forming a rectangular through groove adapted to the window body. The two sides of the through groove near the bottom of the notch are provided with protrusions adapted to the strip grooves 6-1. The window body slides into the strip grooves through the protrusions and is fixedly connected to the fixed handle 3-1. When the two handle seats of the fixed handle 3-1 are interlocked, the two windows can be installed synchronously. The structure is simple, easy to assemble, and firmly installed.

[0037] The right end of the transmission body 5-1 is symmetrically provided with connecting plates 5-1-1 on both sides. The proximal ends of the two connecting plates 5-1-1 are connected to integrally formed support columns 5-1-2. An integrally formed limiting block 5-1-3 is provided on the inner top near the left end. The proximal bottom of the cover plate 5-2 is provided with a limiting plate 5-2-1 that abuts against the support column 5-1-2. The distal end is provided with limiting parts 5-2-2 extending to both sides, and the sides are provided with limiting grooves 5-2-3 that fit the limiting blocks 5-1-3. The limiting parts 5-2 overlap with the distal ends of the corresponding connecting plates 5-1-1, and the limiting blocks 5-1-3 are engaged from bottom to top within the corresponding limiting grooves 5-2-3, thus fixing the cover plate 5-2 to the top of the transmission body 5-1. The structure is simple and installation is convenient.

[0038] To further simplify installation, this embodiment features two symmetrically arranged limiting plates 5-2-1 on both sides of the cover plate 5-2. The bottom of each plate has an arc-shaped groove that matches the outer circumference of the support column, thus limiting the top and sides of the supporting column 5-1-2. This allows the support column to serve as a mounting base during installation, facilitating assembly and resulting in a more stable overall structure. The cover plate 5-2 has ramps 5-2-4 on both sides that slope towards the center, and the top surface of the limiting block 5-1-3 is a downward-sloping surface, facilitating its insertion into the limiting groove 5-2-3.

[0039] A spring is provided between the first transmission seat 4 and the second transmission seat 5. A connecting post is provided near the first transmission seat 4, and the two ends of the spring are respectively fastened to the connecting post and the support post 5-1-2 to achieve an elastic connection between the two transmission seats. In order to avoid interfering with the extension and contraction of the spring, this embodiment also provides an arc-shaped clearance groove 5-2-5 at the center of the bottom surface of the cover plate 5-2, corresponding to the spring, to ensure that the operation performance and feel of the titanium clamp remain unchanged.

[0040] The workflow of this embodiment is as follows: When the titanium clamps are taken out of the packaging box, the movable handle is pulled for the first time to prepare the instrument. At this time, the color mark 8 is located at the firing window 7. The handle is lightly gripped, the second transmission seat 5 moves to the left to feed the nail, and the color mark 8 moves to the nail feeding window 6. The handle is gripped tightly to fire, the second transmission seat 5 moves to the right to reset, and the color mark 8 returns to the firing window 7. After completing a set of actions, the two different states can be clearly distinguished through the window, which is convenient for the operator to use.

[0041] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
