Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a marking titanium clip and a titanium clip assembly. Background Art

[0002] In clinical medicine, for the treatment of patients with malignant tumors, taking gastric cancer as an example, lymph node clearance and accurate determination of which group of lymph nodes have metastasis are closely related to the patient's clinical stage, treatment method and prognosis. As the concept of minimally invasive surgery has become more popular, clinical laparoscopic surgery has become more and more popular. For the current laparoscopic treatment of gastric cancer, titanium clips are first used to clamp the blood vessels around the tumor and lymph nodes, and then the tumor and surrounding lymph nodes are completely removed. After the specimen is taken out, the lymph nodes are grouped.

[0003] Although the above-mentioned method has been widely used in current clinical surgery, there are still some shortcomings, specifically:

[0004] On the one hand, once the tissue is removed from the body, the original position structure will be relatively unclear, so the sorted lymph node specimens are prone to confusion. Therefore, how to accurately match the removed specimens with the specimen removal positions has become an urgent problem to be solved.

[0005] On the other hand, during surgery, most of the current titanium clips are U-shaped or V-shaped. When the titanium clip is installed, it is squeezed by the clip applier to deform the titanium clip and then clamped on the tissue. The stability of the clamping force depends on the structural strength of the deformed part of the titanium clip. However, in actual surgery, the thickness and hardness of tissues vary depending on the location. When the tissue is thicker or harder, the deformed part of the titanium clip needs to have higher strength to ensure a greater clamping force. When the tissue is thinner or softer, if a titanium clip with higher strength at the deformed part is still used, the doctor needs to apply greater pressure when deforming the titanium clip through the clip applier. Under this pressure, it is very easy to cause damage to the tissue, bringing greater medical risks.

[0006] Therefore, there is a need to design a titanium clip structure that can both mark the position of the titanium clip and reduce the risk of the titanium clip damaging tissue during the clipping process. Summary of the invention

[0007] The purpose of the present invention is to provide a titanium clip structure that can mark the position of the titanium clip and reduce the risk of the titanium clip damaging tissue during the clamping process, in response to the problems that the current titanium clips cannot mark the clamping position and easily damage tissue during the clamping process.

[0008] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0009] A marking titanium clip includes a first clip arm, a second clip arm, and a bending portion. The bending portion is bent in a V shape at the middle position. One end of the bending portion is connected to the first clip arm, and the other end is connected to the second clip arm. At least one through hole is provided at the bending position of the bending portion. When there is one through hole, the through hole is located at the middle of the width direction of the bending portion. When there are two or more through holes, the adjacent through holes are spaced apart and evenly distributed along the width direction of the bending portion.

[0010] As one of the preferred solutions, the through hole is a circular through hole.

[0011] As one of the preferred solutions, the through hole is strip-shaped. One end of the through hole is connected to the first clip arm, and the other end extends along the bending portion towards the second clip arm and is connected to the second clip arm.

[0012] As a preferred technical solution, the angle between the first clip arm and the bending portion is equal to the angle between the second clip arm and the bending portion. The first clip arm and the second clip arm are parallel to each other. In the direction from the bottom to the end of the bending portion, the width of the through hole gradually increases.

[0013] As a preferred technical solution, the width of the bending portion is greater than the widths of the first clip arm and the second clip arm.

[0014] As a preferred technical solution, the connection between the bending portion and the first clip arm and the second clip arm is a smooth transition connection.

[0015] As a preferred technical solution, the inner side wall surface of the first clip arm and / or the second clip arm is a frosted surface.

[0016] This application also discloses a titanium clip assembly using the above-mentioned marking titanium clip.

[0017] A titanium clip assembly includes the above-mentioned marking titanium clip, and there are several of the marking titanium clips.

[0018] As a preferred technical solution, among the several marking titanium clips, at least two marking titanium clips have different numbers of through holes.

[0019] As a preferred technical solution, among the several marking titanium clips, at least one marking titanium clip has circular through holes, and at least one marking titanium clip has strip-shaped through holes.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The labeled titanium clip of the present application has through holes provided at the bending positions of the bending parts. The presence of the through holes will reduce the structural strength of the bending positions. When the diameters of the through holes are the same, the more the number of through holes is set, the more the structural strength of the bending positions will be reduced. Therefore, in actual use, for tissues with relatively thick thickness or relatively large hardness, titanium clips with fewer through holes can be selected to make the bending positions have higher strength. After the labeled titanium clips are installed, a relatively large clamping force can be maintained to achieve reliable clamping;

[0022] For tissues with relatively thin thickness or relatively soft texture, titanium clips with more through holes are selected to make the bending positions have relatively small strength, thereby reducing the application pressure of the applicator and further reducing the risk of tissue damage;

[0023] Furthermore, due to the different numbers of through holes, titanium clips with different numbers of through holes can be selected at different clamping positions. Therefore, the positions of the titanium clips can be marked according to the number of through holes. After the specimen is excised, the removed specimen can be marked according to the number of through holes on the labeled titanium clip, so that the removed specimen corresponds to the labeled titanium clip. In this way, the marking of the removed specimen is realized, and the confusion of the removed specimens is avoided;

[0024] In the titanium clip assembly of the present application, since there are through holes on the labeled titanium clip, in actual use, it can be used differently from the conventional titanium clip, thereby realizing the distinction and marking of the clamping positions from the conventional titanium clip. In this way, it is convenient to mark the removed specimen and avoid confusion with specimens at other positions; on the other hand, using the labeled titanium clip of the present application can ensure a reliable clamping force while reducing the application pressure of the applicator, thereby reducing the risk of tissue damage.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0028] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents some embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0029] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0030] It should be noted that like reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the inventive product is usually placed during use, or the orientation or positional relationship commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, terms such as "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0032] Embodiment 1 is as Figure 1 shown:

[0033] A marked titanium clip includes a first clip arm, a second clip arm and a bent portion. The bent portion is bent in a V shape at the middle position. One end of the bent portion is connected to the first clip arm, and the other end is connected to the second clip arm. At least one through hole is provided at the bent portion of the bent portion. When there is one through hole, the through hole is located in the middle of the width direction of the bent portion. When there are two or more through holes, the adjacent through holes are spaced apart and evenly distributed along the width direction of the bent portion.

[0034] For the marked titanium clip of this embodiment, when the applicator clamps the marked titanium clip to the tissue position, and then applies force to the bent portion through the applicator, the bent portion is further bent, that is, the V-shaped opening deforms in the closing direction, so that the first clip arm and the second clip arm approach each other to achieve clamping of the tissue;

[0035] The labeled titanium clip of this embodiment has through holes provided at the bending positions of the bending parts. The presence of the through holes will reduce the structural strength of the bending positions. When the diameters of the through holes are the same, the more the number of through holes is set, the more the structural strength of the bending positions is reduced. Therefore, in actual use, for tissues with a relatively large thickness or high hardness, labeled titanium clips with fewer through holes can be selected to make the bending positions have a higher strength. After the labeled titanium clip is installed, it can maintain a relatively large clamping force to achieve reliable clamping.

[0036] For tissues with a relatively small thickness or relatively soft texture, labeled titanium clips with more through holes are selected to make the bending positions have a smaller strength, thereby reducing the pressure applied by the applicator and further reducing the risk of tissue damage.

[0037] Furthermore, due to the different numbers of through holes, titanium clips with different numbers of through holes can be selected at different clamping positions. Therefore, the position of the titanium clip can be marked according to the number of through holes. After the specimen is excised, the removed specimen can be marked according to the number of through holes on the labeled titanium clip, so that the removed specimen corresponds to the labeled titanium clip. In this way, the marking of the removed specimen is achieved, avoiding confusion of the removed specimens.

[0038] Example 2, as Figure 1 shown:

[0039] A labeled titanium clip, on the basis of the structure of Example 1, further, the through holes are circular through holes. By using circular through holes and arranging the through holes at the bending positions, the processing of the through holes is convenient and fast. Moreover, with such a structure, it will not affect the normal clamping operation of the applicator.

[0040] Example 3, as Figure 1 shown:

[0041] A labeled titanium clip, on the basis of the structure of Example 1, the through holes are strip-shaped. One end of the through hole is connected to the first clip arm, and the other end extends along the bending part towards the second clip arm and is connected to the second clip arm. When the applicator applies force to the bending part to deform the bending position, as the bending degree of the bending position increases, the force required by the applicator also increases to further deform the bending position. Therefore, in the solution of this embodiment, strip-shaped through holes are used, so that the setting of the through holes affects the structural strength of the entire bending part. When the applicator applies force to the bending part to deform the bending part, the entire bending part deforms coordinately to achieve clamping of the tissue, reducing the magnitude of the force applied by the applicator due to the difficulty of deformation in the later stage of the deformation of the bending position, and further reducing the risk of tissue damage caused by excessive force applied by the applicator.

[0042] Preferably, the angle between the first clamping arm and the bending part is equal to the angle between the second clamping arm and the bending part, and the first clamping arm is parallel to the second clamping arm. In the direction from the bottom to the end of the bending part, the width of the through hole gradually increases. With such a structure, the firm clamping of the tissue by the titanium clip depends on the deformation at the bending part and the deformation of the bending parts on both sides of the bending part. The width of the through hole assembly increases, further reducing the deformation requirement at the bending part. In this way, the risk of tissue damage caused by excessive force applied by the applicator is further reduced.

[0043] More preferably, the width of the bending part is greater than the widths of the first clamping arm and the second clamping arm. Setting the width of the bending part wider is beneficial to the arrangement of the through holes, and more through holes can be set, thereby realizing more marking methods.

[0044] More preferably, the connection between the bending part and the first clamping arm and the second clamping arm is a smooth transition connection. On the one hand, it is to avoid the problem of unstable clamping caused by stress concentration, and on the other hand, it also avoids scratching the tissue.

[0045] As a preferred embodiment, the inner wall surface of the first clamping arm and / or the second clamping arm is a frosted surface. By setting the frosted surface, the reliability of clamping the tissue is further improved.

[0046] Example 4, as Figure 1 shown:

[0047] A titanium clip assembly includes the marked titanium clips of any one of Examples 1-3, and there are several of the marked titanium clips.

[0048] In the titanium clip assembly of this embodiment, since there are through holes on the marked titanium clips, in actual use, it can be used differently from the conventional titanium clips, thereby realizing the distinction and marking of the clamping positions from the conventional titanium clips. In this way, it is convenient to mark the removed specimens and avoid confusion with the specimens at other positions; further, as described in Examples 1 and 3, using the marked titanium clips of this embodiment can ensure a reliable clamping force while reducing the pressure applied by the applicator, thereby reducing the risk of tissue damage.

[0049] As a preferred embodiment, among the several marked titanium clips, at least two marked titanium clips have different numbers of through holes. In the titanium clip assembly of this embodiment, at least two marked titanium clips have different numbers of through holes. Different numbers of through holes can also be set on different marked titanium clips. In this way, each titanium clip position can be accurately marked, and at the same time, the removed specimens at different positions can be marked. In this way, the confusion of specimens is further avoided.

[0050] As a preferred embodiment, among the several labeled titanium clips, at least one of the through holes on the labeled titanium clip is a circular through hole, and at least one of the through holes on the labeled titanium clip is a strip-shaped through hole. In this way, through holes with different properties can also be used to distinguish the labeled titanium clips. Thus, it is further convenient to mark the position of the titanium clip, and further avoids the confusion of specimens.

[0051] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although the present specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
