Description

Technical Field

[0001] The utility model relates to the technical field of endoscopic treatment, and more specifically to an improved endoscopic outer sleeve catheter. Background Art

[0002] Endoscopic technology is different from traditional surgical operations. It enables the front end of the endoscope to reach the lesion site in the patient's body, and the treatment operation is performed under direct endoscope vision to complete the entire surgical process. Endoscopic therapy can proactively and effectively solve problems that are difficult to solve with conservative medical treatment, such as acute ruptured esophageal and gastric venous bleeding; it can simplify complex and dangerous treatment methods or replace certain surgeries, such as acute suppurative cholangitis and intrahepatic bile duct stones. It can perform treatment while making a clear diagnosis. It is simple, fast, efficient, safe, does not require anesthesia, causes little damage to patients, has few complications, has a low mortality rate, and has a low total cost. It is accepted by the majority of patients, especially those in critical emergency situations and the elderly with multiple diseases. Endoscopic surgical technology has a curative effect on benign diseases; it can effectively relieve or reduce pain for patients with malignant tumors and improve the quality of life of patients during their survival. The endoscopic guide sheath of the digestive system is mainly suitable for small enteroscopes, and it has two main functions. One is protection. During endoscopic surgery, some endoscopes may need to repeatedly enter and exit the body cavity for operation, while the endoscopic outer sheath can provide a smooth channel to reduce damage between the endoscope and the intestinal tract. The other function is to provide auxiliary support, especially support in the gastric cavity, to help the endoscope maintain a stable position in the body cavity.

[0003] However, in actual work, it is found that the outer sheath catheter is relatively soft and cannot provide effective support, and cannot completely prevent the endoscope from bending or even circling in the gastric cavity. If the hardness of the outer sheath catheter is directly increased, the possibility of intestinal damage will increase. Therefore, the utility model provides an improved endoscope outer sheath catheter. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] Example

[0023] like Figure 1-3 As shown, an improved endoscopic outer sleeve catheter comprises an outer sleeve catheter body 1, wherein four support chambers 2 evenly distributed in an annular shape are opened in the sleeve wall of the outer sleeve catheter body 1, a through opening 3 is opened on the inner wall of the support chamber 2, a support steel wire 4 is embedded in the support chamber 2, and one end of the support steel wire 4 passes through the through opening 3 and extends outward.

[0024] When in use, the four supporting steel wires 4 are first removed from the outer sheath catheter body 1 to improve the flexibility of the outer sheath catheter body 1 and avoid damaging the intestinal tract. The outer sheath catheter body 1 enters the esophagus, stomach and small intestine along with the endoscope. Thereafter, the supporting steel wires 4 can be inserted into the supporting cavity 2 from the opening 3 one by one to improve the supporting force of the outer sheath catheter body 1 and avoid the endoscope from bending and circling in the stomach cavity.

[0025] like Figure 1-3 As shown, the inner wall of the through opening 3 is fixedly connected with a reinforcing ring opening 31 , and the reinforcing ring opening 31 is sleeved on the outer circumferential surface of the supporting steel wire 4 .

[0026] When in use, the inner wall of the through-hole 3 can be protected by the reinforcing ring 31 to prevent deformation and damage at the through-hole 3 during the insertion of the supporting steel wire 4. The reinforcing ring 31 can support the flexible silicone at the through-hole 3, making it convenient for personnel to insert the supporting steel wire 4 from the through-hole 3, thereby improving work efficiency.

[0027] like Figure 1-3 As shown, both ends of the support wire 4 are in arc shape.

[0028] When in use, since both ends of the support steel wire 4 are in arc shape, there are no sharp edges and corners at both ends of the support steel wire 4 to prevent the support steel wire 4 from piercing the inner wall of the support chamber 2 when inserted into the support chamber 2.

[0029] like Figure 1-3 As shown, the outer sheath catheter body 1 is made of silicone material, with an inner diameter of 11 mm, an outer diameter of 14 mm, and a diameter of the supporting steel wire 4 of 1 mm.

[0030] When in use, it can be known from the outer diameter minus the inner diameter that the wall thickness of the outer sheath catheter body 1 is 2 mm, which is sufficient for the support wire 4 with a diameter of 1 mm to be inserted.

[0031] like Figure 1-2As shown, the length from the front end 10 cm of the outer sheath catheter body 1 to the end is 80 cm, and the length of the supporting wire 4 is 85 cm.

[0032] During use, even when the support wire 4 is fully inserted into the outer sleeve catheter body 1 , one end of the support wire 4 still extends 5 cm outside the outer sleeve catheter body 1 , making it convenient for personnel to pull the support wire 4 out of the outer sleeve catheter body 1 .

[0033] In summary, the specific working process of this scheme is: first, four supporting steel wires 4 are removed from the outer sheath catheter body 1 to improve the flexibility of the outer sheath catheter body 1 and avoid damaging the intestinal tract. The outer sheath catheter body 1 enters the esophagus, stomach and small intestine with the endoscope. Thereafter, the supporting steel wires 4 can be inserted into the supporting chamber 2 from the opening 3 one by one, so as to improve the supporting force of the outer sheath catheter body 1 and avoid the endoscope from bending and circling in the stomach cavity.

[0034] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
