TECHNICAL FIELD
[0001] The utility model relates to endoscope medical instrument technical field, specifically is a kind of soft tissue closure clamp for superfine endoscope. BACKGROUND
[0002] If pathological tissue is found during digestive tract endoscopy, minimally invasive treatment under endoscope is needed.Soft tissue closure clamp is a kind of minimally invasive surgical instrument, commonly used for closing wound tissue in patient's body, such as closing wound tissue after resection of pathological tissue in digestive tract, preventing wound perforation, etc.Soft tissue closure clamp can be sent into surgical position in patient's body through endoscope channel, and clamping operation is implemented outside the body to complete tissue closure.Usually, after soft tissue closure clamp closes tissue, granuloma is formed by local tissue inflammation process, and it is self-falling and discharged outside the body through digestive tract, so that the operation has the advantages of small damage, avoiding delayed wound perforation, fewer complications, and definite curative effect, etc.
[0003] At present, gastroscope used in clinical gastroscopy includes superfine gastroscope and ordinary gastroscope.Superfine gastroscope, also known as superfine transnasal gastroscope, has a diameter of only about 5mm, which is one half of the diameter of ordinary gastroscope.Superfine gastroscope can be inserted from nostril, and does not contact tongue root in the process of entering stomach, which greatly reduces the patient's suffering and avoids the defects of vomiting, pain and fear of many patients during ordinary gastroscope examination.Ordinary gastroscope has a relatively thick outer diameter, and is inserted into esophagus and stomach through oral cavity, which causes certain suffering.Some people may have discomfort such as nausea, vomiting and regurgitation.Ordinary gastroscope has an outer diameter of 10-11mm, and its instrument channel has an inner diameter of 2.8mm, which can pass common treatment instruments.Because the instrument channel of superfine gastroscope has a diameter of only 2.2mm, many endoscopic accessories cannot pass the instrument channel of endoscope, so the superfine gastroscope cannot be used for treatment of stomach and esophageal diseases.At present, the outer diameter of soft tissue closure clamp used in clinic is between 2.5mm and 2.7mm, so the instrument channel of endoscope used by the soft tissue closure clamp must be greater than or equal to 2.8mm, so the soft tissue closure clamp used in clinic can only be used for minimally invasive surgery of ordinary gastroscope, and cannot be used for clinical use of superfine transnasal gastroscope.Minimally invasive treatment under superfine transnasal gastroscope cannot be carried out in clinic.

[0041] The scheme in Example 2 is further introduced in combination with a specific working mode, and details are described as follows: the diameter of the mandrel 3 is larger than that of the stepped shaft 34, the rear side of the stepped shaft 34 is provided with a side wall 33, the inner connecting part of the mandrel 3 and the stepped shaft 34 is provided with an inner end face 35, the rear side of the spring piece three 41 abuts against the side wall 33, and the rear side of the connecting sheath tube 4 is provided with a threaded tube 42 structure.
[0042] Example 4:
[0043] The scheme in Embodiment 3 is further introduced in combination with a specific working mode, and details are described below: the conveying structure 5 is arranged at the rear side of the connecting sheath tube 4, the conveying structure 5 comprises a push-pull handle 51, a spring hose 52, a guide wire 53, a hook 54 and a boss 541, the front end of the push-pull handle 51 is fixedly connected with the spring hose 52, the inside of the push-pull handle 51 is provided with the guide wire 53, the inside of the front side of the receiving tube 2 is provided with the hook 54, the rear end of the hook 54 is provided with the boss 541, one end of the guide wire 53 is fixedly connected with the push-pull handle 51, the other end of the guide wire 53 passes through the spring hose 52, the connecting sheath tube 4, the mandrel 3 and the receiving tube 2 in sequence, the other end of the guide wire 53 is fixedly connected with the hook 54, the diameter of the boss 541 is greater than the inner diameter of the stepped shaft 34, the diameter of the boss 541 is less than the inner diameter of the mandrel 3, the spring hose 52 is laser-welded with the threaded tube 42, and the hook 54 is hung on the rear part of the connecting seat 13.
[0044] In specific use, as shown in Figures 7 to 11 , when the push-pull handle 51 in the conveying structure 5 is pulled backward, the clip 1 moves to the inside of the receiving tube 2 under the pulling of the hook 54, the clamping piece one 14 and the clamping piece two 15 of the clip 1 begin to gradually close, because the side wing one 22 and the side wing two 23 of the receiving tube 2 are bent by 90° and are buckled into the opening groove one 31 and the opening groove two 36 of the mandrel 3 respectively, thereby the fixation of the receiving tube 2 and the mandrel 3 is completed, the push-pull handle 51 in the conveying structure 5 is continuously pulled, when the rear end boss 541 of the hook 54 abuts against the inner end surface 35 of the mandrel 3, at this time, the clamping piece one 14 and the clamping piece two 15 of the clip 1 close to each other, the elastic piece one 11 and the elastic piece two 12 of the clip 1 are elastically contracted in the inside of the stepped hole one 24 of the receiving tube 2, at this time, if the push-pull handle 51 in the conveying structure 5 is continuously pulled, resistance is felt, the operator stops pulling the push-pull handle 51, and the clamping piece one 14 and the clamping piece two 15 of the clip 1 realize pre-closing, as shown in Figure 8 and Figure 9 , if the clinician finds that the closed position of the target tissue to be closed is incorrect, the push-pull handle 51 can be pushed forward, the elastic piece one 11 and the elastic piece two 12 of the clip move forward from the inside of the stepped hole one 24 of the receiving tube 2, at this time, the clip 1 can be opened again, as shown in Figure 7 .
[0045] When the clinical operator determines that the target tissue needing to be closed is correct, the push-pull handle 51 in the delivery structure 5 is continuously pulled backward, the rear end boss 541 of the hook 54 abuts against the inner end surface 35 of the mandrel 3, the mandrel 3 moves backward due to the axial pulling force of the hook 54, the side wing one 22 and the side wing two 23 of the receiving tube 2 after being bent 90° are forced to be straightened and deformed and pulled out from the inside of the opening slot one 31 and the opening slot two 36 of the mandrel 3, the receiving tube 2 and the connecting sheath tube 4 are separated from each other, the hook 54 is forced to be straightened due to the pulling force and permanently separated from the connecting seat 13 of the clip 1, as shown in Figure 11 Fig. 6. At this time, the clip 1 is permanently closed, when the clip 1 is permanently closed, the elastic sheet one 11 and the elastic sheet two of the clip 1 enter the step hole two 25 from the step hole one 24 of the receiving tube 2 and abut against and are clamped by the clamping end 21 at the intersection of the step hole one 24 and the step hole two 25, preventing the clip 1 from moving to the front of the receiving tube 2 to reopen, the rear end of the clip 1 is received in the inside of the receiving tube 2 after the soft tissue is closed by the clip 1, the clip 1 is permanently closed and cannot reopen again, as shown in Figure 10 Fig. 7.
