Description

Marking titanium clamp capable of being clamped reliably and titanium clamp assembly

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to mark titanium that can reliably the centre gripping presss from both sides and titanium presss from both sides the subassembly.

Background

In clinical medicine, for the treatment of malignant tumor patients, taking gastric cancer as an example, lymph node cleaning and accurate determination of which group of lymph nodes has metastasis are closely related to the clinical stage, treatment mode and prognosis of patients. With the deep heart of people with the minimally invasive concept, the clinical laparoscopic surgery is more and more popular, and for the treatment of the laparoscopic gastric cancer at present, the titanium clip is firstly adopted to clamp blood vessels around the tumor and the lymph nodes clinically, then the tumor and the lymph nodes around the tumor are completely resected, and the grouping of the lymph nodes is carried out after the specimen is taken out.

Although the above-mentioned methods are widely used in clinical surgery, there are still disadvantages, in particular:

on one hand, once the tissue is separated from the body, the original position structure is relatively unclear, so that the sorted lymph node specimen is easy to be disordered, and therefore, how to accurately correspond the taken specimen to the excision position of the specimen becomes a problem which needs to be solved at present;

on the other hand, during surgery, most of the existing titanium clamps are U-shaped or V-shaped, when the titanium clamps are installed, the titanium clamps are extruded by a clamp applier to deform and then clamped on tissues, the stability of clamping force depends on the structural strength of the deformed part of the titanium clamps, but in actual surgery, the tissue parts are different, the thickness and the hardness are different, when the tissue thickness is thick or the hardness is large, the deformed part of the titanium clamps is required to have higher strength to ensure that the tissue has larger clamping force, otherwise, for the tissues with thicker or larger hardness, after the clamp applier is withdrawn, the titanium clamps are easy to be propped open due to the resilience of tissues at affected parts, so that the clamping is unreliable and even the risk of the titanium clamps dropping is caused; when the tissue is thin or soft, if the titanium clip with high strength at the deformation part is still adopted, a doctor needs to apply larger pressure when deforming the titanium clip through the clip applier, and under the pressure, the tissue is extremely easy to be damaged, so that larger medical risk is brought.

Therefore, at present, a titanium clip structure which can mark the position of the titanium clip, can clamp an affected part controllably and can reduce the risk of damaging tissues by the titanium clip in the clipping process needs to be designed.
