Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a titanium clamp head. Background Art

[0002] Minimizing bleeding is crucial for a successful laparoscopic procedure. Titanium clips are primarily used to clamp intracavitary tissue during laparoscopic surgery and are suitable for ligating internal blood vessels and wounds. Because they are made of titanium alloy, they are called "titanium clips." Application of the titanium clip is primarily accomplished with a titanium clamp, which consists of a head and a clamp assembly for opening and closing the head. Traditional titanium clamps consist of a body and a head. The head, as disclosed in Chinese Utility Model No. CN210249959U, features a shaped entrance to the nail slot, a threshold at the exit, and positioning slots and openings on opposing sides. This complex overall structure necessitates a separate design from the body, manufactured separately and then assembled through welding. This head structure carries a high risk of breakage during use, necessitating optimization of the existing structure. Utility Model Content

[0003] The purpose of the utility model is to propose a titanium clamp head in response to the deficiencies of the existing technology. The clamp head structure is more streamlined, thereby realizing an integrated design, improving the overall structural strength and avoiding breakage.

[0004] The technical solution to achieve the purpose of this utility model is:

[0005] A titanium clamp head includes an integrally formed clamp body and a clamp head. Two connecting rods are symmetrically provided at the distal end of the clamp body. The clamp head includes a chuck symmetrically provided on the two connecting rods. The inner sides of the chucks are parallel to each other and are provided with a nail outlet groove arranged along the length direction. The entrance of the nail outlet groove is provided with an outwardly expanding arc surface, and the outlet extends to the distal end of the chuck.

[0006] Furthermore, the chuck includes a connecting section, a transition section and a clamping section that are connected in sequence, the connecting section is connected to the connecting rod and is horizontally arranged, the transition section is inclined downward, the clamping section is inclined upward and the distal end is higher than the clamp body, and the nail outlet groove is arranged in the clamping section.

[0007] Furthermore, the width of the connecting section gradually increases from the proximal end to the distal end, and the widths of the transition section and the clip applying section gradually decrease from the proximal end to the distal end.

[0008] Furthermore, the distal end of the clip applying section is provided with a smooth chamfer.

[0009] Furthermore, the pliers body portion includes a pliers body, a positioning connection portion is provided at the proximal end of the pliers body, and a V-shaped groove is provided at the distal end to form two connecting ends, and the two connecting rods are arranged in parallel and respectively connected to the two connecting ends.

[0010] Furthermore, the distance between the two connecting rods is greater than the distance between the two connecting ends, and an inclined transition rod is connected between the connecting ends.

[0011] Furthermore, the positioning connection portion includes a circular positioning through hole and an elongated connecting through groove that are aligned along the axial direction.

[0012] By adopting the above technical solution, the utility model has the following beneficial effects:

[0013] (1) The present invention simplifies the structure of the pliers head and lays the foundation for the integrated design of the pliers head and the pliers body. The integrated design avoids welding points, which not only simplifies the production process but also improves the connection strength of the entire pliers head and avoids breakage. In addition, since the entire pliers head adopts an integrated structural design, the relative position accuracy of the two chucks is guaranteed, which is almost completely symmetrical, avoiding the slight asymmetry of the two chucks due to the size difference during welding and assembly in the traditional structure, which causes mutual misalignment during clamping. This improves the product qualification rate and clamping reliability, and eliminates the design of positioning grooves and positioning ports, saving costs. The integrated structural design also ensures that the inner sides of the two chucks are almost completely parallel, improving the reliability of fixing the titanium clip. There is no need for the traditional threshold structure to assist in fixing the titanium clip, which not only makes the processing of the nail groove easier, but also facilitates the inspector to directly place the titanium clip from the far end of the pliers head to check the symmetry of the two chucks, further improving production efficiency.

[0014] (2) The clamping head of the present invention is composed of a connecting section, a transition section and a clamping section located in different planes, so that there is a certain angle difference between the plane where the clamping section of the clamping part is located and the plane where the clamp body is located, so that it is not easy to block the line of sight during actual use, and the clamping operation is more convenient.

[0015] (3) The width of the forceps head of the utility model is designed to gradually increase and then decrease, which not only improves the structural strength of the forceps head, but also expands the proximal end and cooperates with the outer tube of the forceps body assembly to achieve natural closure of the forceps head and contraction of the distal end, making it easier for doctors to manipulate the forceps head to approach and move away from specific tissues.

[0016] (4) The distal end of the forceps head of the utility model is provided with a smooth chamfer to avoid puncturing tissue and improve surgical safety.

[0017] (5) The utility model adopts a V-groove design to naturally form two connection ends. At the same time, when the clamp head is retracted into the clamp body assembly, it can be closed more naturally to achieve the purpose of clamping the titanium clamp.

[0018] (6) The utility model uses an inclined transition rod to connect connecting rods and connecting ends with different spacings. Compared with a vertical transition, when closed under the action of external force, the stress distribution is more uniform, weak connection points are less likely to appear, and the service life is longer.

[0019] (7) The utility model adopts a positioning connection part composed of a circular positioning hole and a long strip connecting groove. The positioning hole adopts a circular structure design to ensure the assembly accuracy with the clamp body assembly. At the same time, the connecting groove adopts a long strip structure design to reduce the dimensional accuracy requirements, save manufacturing costs, and facilitate assembly.

DETAILED DESCRIPTION

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] (Example 1)

[0029] like Figures 1 to 4The titanium clamp head shown includes an integrally formed body 1 and head 2, eliminating welds and simplifying the production process while increasing the joint strength of the entire clamp head and preventing breakage. Two connecting rods 1-1 are symmetrically positioned at the distal end of the body 1. The head 2 includes a clamp 2-1 symmetrically positioned on the two connecting rods 1-1. The inner sides of the clamps 2-1 are parallel to each other and define a nail outlet slot 2-1-1 extending along their length. The entrance of the nail outlet slot 2-1-1 is provided with an outwardly flaring arcuate surface, and the exit extends to the distal end of the clamp 2-1. Due to the integrated structural design, the inner sides of the two chucks 2-1 are guaranteed to be completely parallel and symmetrical. The titanium clip can be clamped through the mutually parallel inner sides, thereby improving the reliability of fixing the titanium clip. There is no need for a threshold structure of the traditional structure to assist in fixing the titanium clip. This not only makes the processing of the nail groove 2-1-1 easier, but also makes it convenient for inspectors to directly place the titanium clip from the far end of the pliers head to check the symmetry of the two chucks, and eliminates the structural design of the positioning groove and positioning port in the traditional structure, thereby further improving production efficiency.

[0030] Specifically, the pliers body 1 includes a pliers body 1-2. The proximal end of the pliers body 1-2 is provided with a positioning connection portion 1-3 for connecting to the pliers body assembly. The distal end is provided with a V-shaped groove 1-4, forming two connecting ends, so that when the pliers head is retracted into the pliers body assembly, it can be closed more naturally to achieve the purpose of clamping the titanium clamp. Two connecting rods 1-1 are arranged in parallel and are respectively connected to the two connecting ends. The spacing between the two connecting rods 1-1 is greater than the spacing between the two connecting ends, and an inclined transition rod 1-5 is connected between the connecting ends. The transition rod 1-5 is used to connect the connecting rods and connecting ends with different spacings. Compared with a vertical transition, when closing under the action of external force, the stress distribution is more uniform, and it is less likely to have weak connection points, which has a longer service life. The positioning connection part 1-3 includes a positioning through hole 1-3-1 and a connecting through slot 1-3-2 aligned along the axial direction. The positioning through hole 1-3-1 adopts a circular structure to ensure the assembly accuracy with the clamp body assembly. The connecting through slot 1-3-2 adopts a long strip structure design, which reduces the dimensional accuracy requirements of the assembly connection, saves manufacturing costs, and facilitates assembly.

[0031] The clamping head 2-1 comprises a connecting section 2-1-2, a transition section 2-1-3, and a clamping section 2-1-4, which are sequentially connected. The nail outlet slot 2-1-1 is located in the clamping section 2-1-4. The connecting section 2-1-2 is connected to the connecting rod 1-1 and is arranged horizontally. The transition section 2-1-3 is tilted downward, and the clamping section 2-1-4 is tilted upward, with its distal end higher than the clamp body. This creates a certain angle difference between the plane of the clamping section and the plane of the clamp body at the clamping site. This prevents the clamping section from obstructing vision during use, making clamping easier.

[0032] The width of the connecting section 2-1-2 gradually increases from proximal to distal, while the width of the transition section 2-1-3 and the clamping section 2-1-4 gradually decreases from proximal to distal. This not only enhances the structural strength of the forceps head, but also expands at the proximal end, cooperating with the outer tube of the forceps body assembly to achieve natural closure of the forceps head, while the distal end contracts, making it easier for the surgeon to maneuver the forceps head toward and away from specific tissues. The distal end of the clamping section 2-1-4 features a smooth chamfer to prevent tissue damage and enhance surgical safety.

[0033] The present invention simplifies the structure of the pliers head and lays the foundation for the integrated design of the pliers head 2 and the pliers body 1. The integrated design avoids welding points, which not only simplifies the production process, but also improves the connection strength of the entire pliers head and avoids breakage. In addition, since the entire pliers head adopts an integrated structural design, the relative position accuracy of the two clamps 2-1 is guaranteed, which is almost completely symmetrical, avoiding the slight asymmetry of the two clamps 2-1 caused by the size difference during welding and assembly in the traditional structure, which causes mutual misalignment when clamping, thereby improving the product qualification rate and clamping reliability, and eliminating the design of positioning grooves and positioning ports, saving costs. The integrated structural design also ensures that the inner sides of the two clamps are almost completely parallel, improving the reliability of fixing the titanium clamp, and eliminating the need for the threshold structure of the traditional structure to assist in fixing the titanium clamp. It not only makes the processing of the nail groove simpler, but also makes it convenient for inspectors to directly place the titanium clamp from the far end of the pliers head to check the symmetry of the two clamps, thereby further improving production efficiency.

[0034] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
