Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a surgical positioning forceps. Background Technology

[0002] Surgical locator forceps are crucial tools in surgical procedures for precisely grasping and positioning tissues or instruments, and their performance directly affects the accuracy and safety of the surgical operation. During surgery, medical staff need to hold the forceps handles for extended periods to perform delicate operations; therefore, surgical locator forceps require a rubber coating on the handle portion during design and manufacturing.

[0003] In existing technologies, the handle coating of surgical positioning forceps often uses a single coating layer directly sleeved or glued to the surface of the handle. While this design can achieve basic insulation and improved grip to some extent, it still has certain drawbacks:

[0004] 1. The fixation of a single rubber layer to the pliers handle relies on glue or interference fit. After repeated disinfection, high temperature and high pressure treatment or long-term use, the rubber layer is prone to peeling off and curling, resulting in the exposure of the metal pliers body. This not only affects the insulation performance, but may also interfere with the operation accuracy due to the loosening of the rubber layer.

[0005] 2. The one-piece molded or glued coated structure cannot be disassembled separately. If the coating is damaged, the entire pliers handle needs to be replaced, which increases the maintenance cost of the instrument. At the same time, the complicated assembly process also reduces production efficiency and is not conducive to large-scale production.

[0006] 3. Due to factors such as the thickness and shape of the overmolding, the metal clamp handle is in a loose state inside the mold during injection molding. This makes the clamp handle prone to displacement or glue leakage during the injection molding process, which directly affects the performance and aesthetics of the surgical positioning forceps.

[0007] Therefore, in view of the above situation, there is an urgent need to develop a surgical positioning forceps to overcome the shortcomings in current practical applications. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide a surgical positioning forceps to solve the problems in the background technology mentioned above.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A surgical positioning forceps includes a first forceps body and a second forceps body. The first forceps body is composed of a first forceps head and a first forceps handle. The second forceps body is composed of a second forceps head and a second forceps handle. The first forceps head is connected to the second forceps head. Each of the first forceps handle and the second forceps handle is equipped with an adhesive-coated assembly, an electrode lead, and an electrode plate. The electrode lead is electrically connected to the electrode plate.

[0011] The coating assembly includes a first coating and a second coating. The first coating is installed inside the first and second clamp handles and is tightly fitted to their inner walls. The second coating is installed on the outside of the first and second clamp handles and is located above the first coating. The first coating has adhesive posts distributed on it, which engage with the post holes distributed on the second coating. Electrode leads and electrode plates are installed on the second coating. The adhesive posts and post holes achieve a quick connection between the second coating and the first coating by engaging with each other, thus wrapping the first and second clamp bodies.

[0012] As a further technical solution of this utility model, both the first pliers head and the second pliers head are provided with mutually cooperating hinge holes, and a hinge shaft is installed in the hinge hole. The first pliers head is rotatably connected to the second pliers head through the hinge shaft.

[0013] As a further technical solution of this utility model, both the first clamp handle and the second clamp handle are made of metal clamp handles, and the sides of both the first clamp handle and the second clamp handle are distributed with semi-circular serrated grooves.

[0014] As a further technical solution of this utility model, side grooves are provided on both sides of the first coated end.

[0015] As a further technical solution of this utility model, the glue column and the first glue coating are integrally injection molded, and the column hole and the second glue coating are integrally injection molded.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The interlocking mechanism between the glue column and the column hole not only enables the quick connection between the second and first glue layers, reducing assembly time, but also allows for the wrapping of the first and second clamp bodies, increasing the stability of the wrapping and making the entire clamp handle part a single structure, which is convenient for the operator to control.

[0018] The first layer of adhesive adheres tightly to the inner wall of the forceps handle, effectively isolating the metal parts of the forceps from direct contact with the outside, thus avoiding the risk of electric leakage during surgery. The second layer of adhesive wraps around the outside of the forceps handle, and the electrode plate is mounted on the second layer of adhesive. This prevents medical staff from accidentally touching the electrode plate during operation, thus preventing electric shock. It also reduces the risk of short circuits caused by accidental contact between the electrode plate and other instruments.

[0019] Furthermore, the step-by-step injection molding of the first and second rubber coatings ensures that the first and second clamp bodies are relatively stable in the mold, preventing displacement or rubber leakage during the injection molding process and ensuring the overall aesthetics of the surgical positioning forceps.

[0020] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 4 As shown, a surgical positioning forceps provided as an embodiment of the present utility model includes a first forceps body 1 and a second forceps body 2. The first forceps body 1 is composed of a first forceps head 11 and a first forceps handle 12, and the second forceps body 2 is composed of a second forceps head 21 and a second forceps handle 22. The first forceps head 11 is connected to the second forceps head 21. The first forceps handle 12 and the second forceps handle 22 are each equipped with a rubber-coated assembly 5, an electrode lead 3 and an electrode plate 6. The electrode lead 3 is electrically connected to the electrode plate 6. When the electrode plates 6 on the first forceps handle 12 and the second forceps handle 22 are in contact with each other, they can transmit electrical signals to the outside through the electrode lead 3, thereby providing timely feedback on the fixation status of the surgical positioning forceps.

[0029] The coating assembly 5 includes a first coating 51 and a second coating 53. The first coating 51 is installed inside the first clamp handle 12 and the second clamp handle 22 respectively and is tightly fitted to their inner walls. The second coating 53 is installed on the outside of the first clamp handle 12 and the second clamp handle 22 respectively. The second coating 53 is located above the first coating 51. The first coating 51 has adhesive pillars 52 distributed on it. The adhesive pillars 52 engage with the pillar holes 54 distributed on the second coating 53. The second coating 53 is equipped with electrode leads 3 and electrode plates 6. The adhesive pillars 52 and pillar holes 54 engage with each other, which not only enables the quick connection between the second coating 53 and the first coating 51, reducing assembly time, but also completes the wrapping of the first clamp body 1 and the second clamp body 2, increasing the stability of the wrapping of the first clamp body 1 and the second clamp body 2, so that the entire clamp handle part forms an integral structure, which is convenient for the operator to control.

[0030] The first adhesive layer 51 fits tightly against the inner wall of the forceps handle, effectively isolating the metal parts of the forceps body from direct contact with the outside, thus avoiding the risk of electric leakage during surgery. The second adhesive layer 53 wraps around the outside of the forceps handle, and the electrode plate 6 is installed on the second adhesive layer 53, which can prevent medical staff from accidentally touching the electrode plate 6 during operation and causing electric shock, while also reducing the possibility of short circuits caused by accidental contact between the electrode plate 6 and other instruments.

[0031] Furthermore, the stepwise injection molding of the first rubber coating 51 and the second rubber coating 53 ensures that the first clamp body 1 and the second clamp body 2 are relatively stable in the mold, avoiding displacement or rubber leakage of the first clamp body 1 or the second clamp body 2 during the injection molding process, thus ensuring the overall aesthetics of the surgical positioning forceps.

[0032] like Figures 1 to 4 As shown, in a preferred embodiment of the present invention, the first pliers 11 and the second pliers 21 are each provided with a hinge hole 4 that cooperates with each other. A hinge shaft is installed in the hinge hole 4, and the first pliers 11 is rotatably connected to the second pliers 21 through the hinge shaft.

[0033] like Figures 2 to 4 As shown, in a preferred embodiment of the present invention, the first pliers handle 12 and the second pliers handle 22 are preferably made of metal, and the sides of the first pliers handle 12 and the second pliers handle 22 are distributed with semi-circular serrated grooves 7. The serrated grooves 7 can increase the contact area between the first pliers handle 12 and the second pliers handle 22 and the first adhesive 51, thereby improving the bonding degree between the two and the first adhesive 51.

[0034] like Figures 2 to 4As shown in the preferred embodiment of this utility model, side grooves 55 are provided on both sides of one end of the first rubber coating 51. The side grooves 55 can segment one end of the first rubber coating 51, so that one end of the first rubber coating 51 has a certain elasticity. This allows the outer side of the first rubber coating 51 to fully and effectively contact the inner wall of the first clamp handle 12 or the second clamp handle 22 when it is installed inside the first clamp handle 12 or the second clamp handle 22, thereby increasing the friction between the two and improving the connection stability between the first rubber coating 51 and the first clamp handle 12 or the second clamp handle 22, and improving the overall stability of the surgical positioning forceps structure.

[0035] like Figures 2 to 4 As shown, in a preferred embodiment of this utility model, the glue column 52 and the first glue coating 51 are integrally injection molded, and the column hole 54 and the second glue coating 53 are integrally injection molded. This not only improves the structural strength of the first glue coating 51 and the second glue coating 53, but also ensures that the glue column 52 can be precisely matched with the column hole 54, thereby achieving a stable connection between the first glue coating 51 and the second glue coating 53.

[0036] 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 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.
