Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a symbol-marked 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] 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. When confusion occurs, medical staff can only place the sorted lymph node specimens at the tissue and compare them with the incision shape at the tissue to determine whether the lymph node specimen is cut from that place. This method is troublesome to operate and prone to errors. On the other hand, for some tissues, dozens or even more lymph nodes may be sorted. When sorting such a large number of lymph nodes, if the lymph node specimens are confused, it is extremely difficult to restore the tissue position of the lymph node specimens, which requires a lot of energy and time. Therefore, how to accurately match the removed specimens with the specimen removal position has become a problem that needs to be solved urgently. Summary of the invention

[0005] The purpose of the present invention is to provide a titanium clip structure capable of marking the clipping positions, in order to solve the problem that the current titanium clips cannot mark the clipping positions, which leads to the difficulty in distinguishing the clipping positions and easy confusion when there are many clipping positions.

[0006] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0007] A symbol-marked titanium clip comprises a titanium clip body, wherein the titanium clip body comprises a first clamp arm, a second clamp arm and a bent portion, wherein the bent portion is bent in a V-shape or a U-shape in the middle, wherein one end of the bent portion is connected to the first clamp arm, and the other end is connected to the second clamp arm, wherein a marking portion is provided on the first clamp arm and / or the second clamp arm and / or the bent portion, wherein a marking symbol is provided on the marking portion, and wherein the marking symbol is formed by a local depression and / or a local protrusion of the titanium clip body.

[0008] The symbol-marked titanium clips of the present application. Different titanium clips are distinguished or their positions are corresponding by setting the same or different marking symbols, so as to distinguish different clip application positions or make the same corresponding markings at the same position. In this way, the positions of the lymph node corresponding tissues can be accurately located, which is particularly suitable for the sorting work involving a large number of lymph nodes, avoiding the occurrence of confusion in the corresponding positions of lymph nodes, greatly improving the work efficiency of medical staff and reducing the work difficulty of medical staff.

[0009] As a preferred technical solution, the marking symbol is in the shape of a number.

[0010] As a preferred technical solution, the marking symbol is in the shape of a letter.

[0011] As a preferred technical solution, the marking symbol is a raised or sunken dot

[0012] As a preferred technical solution, the marking symbol is a through hole.

[0013] As a preferred technical solution, the through hole is arranged at the bending part of the titanium clip body.

[0014] As one of the preferred solutions, the through hole is a circular through hole.

[0015] 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 part towards the second clip arm and is connected to the second clip arm.

[0016] As a preferred technical solution, a transparent layer is coated on the titanium clip body corresponding to the marking symbol. The transparent layer is made of a transparent material, and there are prism surfaces or curved surfaces on the transparent layer corresponding to the marking symbol. The transparent layer is used to magnify the marking symbol for convenient observation by medical staff.

[0017] As a preferred technical solution, the transparent layer is made of medical silicone material.

[0018] As a preferred technical solution, the transparent layer is made of a soft medical silicone material.

[0019] As a preferred technical solution, the fit between the transparent layer and the titanium clip body is rotatable.

[0020] The present application also discloses a titanium clip assembly,

[0021] including at least two of the above symbol-marked titanium clips, and the marking symbols on at least two of the symbol-marked titanium clips are different.

[0022] As a preferred technical solution, at least two of the marking symbols on the symbol-marked titanium clips are the same.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] For the symbol-marked titanium clips of the present application, different titanium clips are distinguished or the positions of different titanium clips are corresponded by setting the same or different marking symbols, so as to distinguish different clip application positions or make the same corresponding marks at the same position, which can accurately locate the positions of the lymph node corresponding tissues, and is particularly suitable for the sorting work involving a large number of lymph nodes, avoiding the occurrence of confusion in the corresponding positions of the lymph nodes, greatly improving the work efficiency of medical staff and reducing the work difficulty of medical staff;

[0025] When the marking symbol is a number or a letter, it can be conveniently recognized by medical staff;

[0026] When the marking symbol is in the form of a through hole, through holes are provided at the bending part of the bending portion. The setting of the through holes will reduce the structural strength of the bending part. 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 part is reduced. Therefore, in actual use, for tissues with a relatively thick thickness or a relatively large hardness, symbol-marked titanium clips with fewer through holes can be selected to make the bending part have a higher strength. After the symbol-marked titanium clip is installed, a relatively large clamping force can be maintained to achieve reliable clamping;

[0027] For tissues with a relatively thin thickness or a relatively soft texture, symbol-marked titanium clips with more through holes are selected to make the bending part have a relatively small strength, so as to reduce the application pressure of the applicator and further reduce the risk of tissue damage;

[0028] 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 removed, the removed specimen can be marked according to the number of through holes on the symbol-marked titanium clip, so that the removed specimen corresponds to the symbol-marked titanium clip. In this way, the marking of the removed specimen is realized, and the confusion of the removed specimen is avoided;

[0029] Due to the presence of facets or curved surfaces on the transparent layer, the marking symbol is magnified, which is convenient for medical staff to observe;

[0030] Furthermore, the transparent layer is made of a soft medical silicone material. During the clamping process of the applicator, if slippage or mutation occurs at the clamped tissue, the soft silicone material can also play a buffering role to avoid excessive force applied by the applicator, resulting in excessive pressure between the first clamping arm and the second clamping arm and damaging the tissue;

[0031] When the transparent layer and the titanium clip body are in a rotatable fit, medical staff can rotate the transparent layer to face the surface or edge of the transparent layer that can magnify the marking symbol towards the medical staff, which further facilitates the medical staff's identification of the marking symbol.

[0032] In the titanium clip assembly of the present application, since there are marking symbols on the symbol-marked titanium clip, in actual use, it can be used differently from the symbol-marked titanium clips with different symbols and 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 specimens in other positions. Further, when using the symbol-marked titanium clip of the present application, while ensuring a reliable clamping force, it can also reduce the application pressure of the applicator, thereby reducing the risk of tissue damage.

[0047] Embodiment 1, as Figures 1-6 shown:

[0048] A symbol-marked titanium clip includes a titanium clip body 1. The titanium clip body 1 includes a first clip arm 2, a second clip arm 3, and a bending portion 4. The bending portion 4 is bent in a V shape or a U shape at the middle position. One end of the bending portion 4 is connected to the first clip arm 2, and the other end is connected to the second clip arm 3. A marking portion is provided on the first clip arm 2 and / or the second clip arm 3 and / or the bending portion 4, and a marking symbol 5 is provided on the marking portion. The marking symbol 5 is formed by means of local depression and / or local protrusion of the titanium clip body 1.

[0049] The symbol - marked titanium clips in this embodiment. Different titanium clips can distinguish different titanium clips or correspond to the positions of different titanium clips by setting the same or different marking symbols 5, so as to distinguish different clip - applying positions or make the same corresponding marks at the same position. For example, in tumor surgery, since tumor cells will metastasize after a certain stage, and the first site of metastasis is the lymph nodes around the tumor tissue. If the lymph nodes have metastasized but have not been dissected, there is a high possibility of rapid recurrence. Therefore, during tumor surgery, when the cancerous tissue is removed, it is generally necessary to remove the nearby lymph nodes and lymphatic tissues at the same time. After the tumor and the surrounding lymphatic tissues are removed, lymph node dissection is required, and pathological examination of the lymph nodes is carried out to evaluate the metastasis of tumor cells. By using the symbol - marked titanium clips of this application, when the lymphatic tissue is removed, since the lymphatic tissue is usually in a bloody and blurred state after being removed from the body and it is difficult to correspond to the position of the tissue in the body, therefore, by adopting the solution of this application, titanium clips with the same marking symbol 5 can be applied to the in - vivo tissue and the lymphatic tissue, so as to clearly define the corresponding relationship between the lymphatic tissue after being removed from the body and the in - vivo tissue, and then deduce the metastasis of cancer cells in the body through the pathological examination of the lymphatic tissue; when performing lymph node dissection in the lymphatic tissue, different marking symbols 5 of titanium clips are used to clip different positions of the tissue. In this way, the distinction between different lymph nodes corresponding to different tissue positions is realized; the sorted lymph nodes can be marked with titanium clips with the same marking symbol 5, or can be marked with other marking structures with the same marking symbol 5 as the sorting site. For example, specimen boxes with the same marking symbol 5 as the sorting site are used to store the lymph nodes. In this way, the position of the lymph nodes corresponding to the tissue can be accurately located, which is especially suitable for the sorting work involving a large number of lymph nodes, avoiding the occurrence of confusion in the corresponding positions of the lymph nodes, greatly improving the work efficiency of medical staff and reducing the work difficulty of medical staff.

[0050] As an implementation manner, further, the marking symbol 5 is in the shape of a number.

[0051] As an implementation manner, the marking symbol 5 is in the shape of a letter.

[0052] As described above, when the marking symbol 5 is a number or a letter, it can be easily recognized by medical staff, which is further convenient for use.

[0053] As an implementation manner, the marking symbol 5 is a raised or sunken dot. The marking symbol 5 is formed in the form of a raised or sunken dot. By setting different numbers of sunken and / or raised points on different titanium clips, the distinction between different symbol - marked titanium clips is realized. In this way, the manufacturing process of the symbol - marked titanium clip is simple and convenient.

[0054] As an implementation manner, the marking symbol 5 is a through - hole, as Figure 5As shown in the figure. By setting the same or different through-holes on different titanium clips, the position correspondence or marking of the titanium clips can be realized.

[0055] As a preferred method, the through-hole is arranged at the bending part of the bending part 4 of the titanium clip body 1.

[0056] When the marking symbol 5 adopts the through-hole method, through-holes are arranged at the bending part of the bending part 4. The setting of the through-holes will reduce the structural strength of the bending part. 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 part is reduced. Therefore, in actual use, for tissues with a relatively thick thickness or a relatively large hardness, titanium clips with fewer through-holes can be selected for marking, so that the bending part has a higher strength. After the titanium clip with the symbol marking is installed, a larger clamping force can be maintained to achieve reliable clamping.

[0057] For tissues with a relatively thin thickness or a relatively soft texture, titanium clips with more through-holes are selected for marking, so that the bending part has a smaller strength, thereby reducing the application pressure of the applicator and further reducing the risk of tissue damage.

[0058] 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 removed, the removed specimen can be marked according to the number of through-holes on the titanium clip with the symbol marking, so that the removed specimen corresponds to the titanium clip with the symbol marking. In this way, the marking of the removed specimen is realized, and the confusion of the removed specimen is avoided.

[0059] As one of the methods, the through-hole is a circular through-hole.

[0060] As one of the methods, the through-hole is strip-shaped and is not shown in the accompanying drawings of the specification. One end of the through-hole is connected to the first clip arm 2, and the other end extends along the bending part 4 towards the second clip arm 3 and is connected to the second clip arm 3.

[0061] Embodiment 2, as Figures 1-6 shown,

[0062] A titanium clip with a symbol marking. On the basis of the above embodiment, further, a transparent layer 6 is coated on the titanium clip body 1 corresponding to the marking symbol 5. As Figure 6 shown, the transparent layer 6 is made of a transparent material, and there are prism surfaces or curved surfaces on the transparent layer 6 corresponding to the marking symbol 5. The transparent layer 6 is used to magnify the marking symbol 5 for the convenience of medical staff to observe. Due to the prism surfaces or curved surfaces on the transparent layer 6, the marking symbol is magnified, which is convenient for medical staff to observe.

[0063] As a preferred implementation method, the transparent layer 6 is made of a medical silicone material.

[0064] As a preferred embodiment, the transparent layer 6 is made of a soft medical silicone material. The soft medical silicone material is a common medical silicone material currently used in the current medical technology field, such as oxygen delivery tubes and infusion tubes, etc. It can provide a certain degree of deformation after being subjected to force. The transparent layer 6 is made of a soft medical silicone material. During the clamping process of the clip applicator, if the clamped tissue slips or suddenly changes, the soft silicone material can also play a buffering role to prevent the clip applicator from applying too much force, resulting in excessive pressure between the first clamp arm 2 and the second clamp arm 3 and damaging the tissue.

[0065] As a preferred technical solution, the transparent layer 6 is rotatably matched with the titanium clip body 1. When the transparent layer 6 is rotatably matched with the titanium clip body 1, medical staff can rotate the transparent layer 6 to make the surface or edge of the transparent layer 6 that can magnify the marking symbol face the medical staff, further facilitating the medical staff to identify the marking symbol 5.

[0066] Embodiment 3, as Figures 1-6 Shown:

[0067] A titanium clip assembly comprises at least two symbol-marked titanium clips as described in the above-mentioned embodiment 1 or 2, wherein the marking symbols 5 on at least two of the symbol-marked titanium clips are different.

[0068] As a preferred technical solution, at least two of the marking symbols 5 on the symbol-marked titanium clips are identical.

[0069] Since there is a marking symbol 5 on the symbol-marked titanium clip, in actual use, a variety of marking symbols 5 can be formed on different symbol-marked titanium clips in the same group of symbol-marked titanium clips, and can be used differently from symbol-marked titanium clips with different symbols and conventional titanium clips, thereby achieving the distinction and marking of the clamping position from the conventional titanium clips, which facilitates the marking of the removed specimens and avoids confusion with specimens at other positions; on the other hand, the titanium clip assembly of this embodiment can reduce the application pressure of the clamp applier while ensuring reliable clamping force, thereby reducing the risk of tissue damage.

[0070] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
