Description

Technical Field

[0001] The utility model relates to the technical field of digestive tract foreign bodies, in particular to a digestive tract foreign body grabbing device. Background Art

[0002] The digestive tract is a long muscular tube that starts from the mouth and continues to the pharynx, esophagus, stomach, small intestine, large intestine and end at the anal canal. It includes the mouth, pharynx, esophagus, stomach, small intestine, large intestine and anal canal. Foreign bodies in the digestive tract mostly occur in infants, patients or those who attempt suicide. Most of them have no clinical symptoms and foreign bodies can be discharged through the anus by themselves. However, some patients require surgical treatment due to difficulty in expelling foreign bodies or complications.

[0003] Foreign bodies in the digestive tract are generally divided into exogenous and endogenous. Persimmon stones, hair stones and various swallowed foreign bodies are common in clinical practice. The use of gastroscopy and X-ray examinations can help to confirm the diagnosis. Exogenous foreign bodies are foreign bodies swallowed into the stomach. There are many kinds of foreign bodies, and the common ones are buttons, dentures, coins, animal bone spurs, etc. Swallowed foreign bodies are easily blocked and retained in the esophagus of the digestive tract, which can easily cause direct damage to the digestive tract and cause mucosal erosion and ulcers in the digestive tract and digestive tract bleeding. With the popularization and development of endoscopes in recent years, some foreign bodies in the digestive tract can be removed non-invasively with the help of endoscopes and foreign body forceps, thereby reducing the risk of postoperative complications.

[0004] However, the aforementioned clamping method requires the use of a variety of instruments, which is not only cumbersome to use, but also easily increases the patient's pain and easily causes secondary damage to the patient's digestive tract. There are many deficiencies in the operation process. Utility Model Content

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0029] Figure 1 and Figure 2 The first embodiment of the utility model is shown: a digestive tract foreign body grasping device, comprising a flexible interventional catheter 1, a clamping mechanism 2 arranged at one end of the flexible interventional catheter 1, and a holding mechanism 3 arranged at the other end of the flexible interventional catheter 1; a lighting and video mechanism 4 is also arranged in the clamping mechanism 2; wherein: the holding mechanism 3 is used to control the movement of the clamping mechanism 2, so as to grasp the foreign body according to the digestive tract image taken by the lighting and video mechanism 4.

[0030] See also Figures 3 to 7 In a specific implementation, the clamping mechanism 2 includes a rigid sleeve 201 and a first mounting seat 202 and a second mounting seat 203 respectively arranged at the pipe openings at both ends of the rigid sleeve 201; a plurality of clamping jaws 204 are hinged on the circumferential side of the first mounting seat 202, and a connecting rod 205 is hinged on each of the clamping jaws 204, and the ends of each of the connecting rods 205 are hinged on the pipe wall of the telescopic tube through a support ear 206, and the telescopic tube is inserted into the first mounting seat 202; a plurality of pull ropes 209 are also connected to the pipe opening of the telescopic tube through a flange 208, and each of the pull ropes 209 passes through the second mounting seat 203 and then converges into a pull rope 210, and the pull rope 210 extends along the lumen of the flexible interventional catheter 1 to the holding mechanism 3; a spring 211 is also arranged between the flange 208 and the second mounting seat 203. The holding mechanism 3 includes a fixed handle 301 and a movable handle 302 hinged to the fixed handle 301 at a side away from the flexible interventional catheter 1 . The pull cable 210 passes through the fixed handle 301 and its end is connected to the movable handle 302 .

[0031] In this embodiment, the medical staff applies a gripping force to rotate the movable handle 302 toward the fixed handle 301, so that the movable handle 302 pulls the cable 210 outward. Under the action of the cable 210, the pull rope 209 can drag the telescopic tube to move along the second mounting seat 203. At this time, the spring 211 is compressed, and each clamping jaw 204 is radially expanded under the action of the connecting rod 205; conversely, when the medical staff stops applying a gripping force to the movable handle 302, the spring 211 is reset and pushes the telescopic tube to move away from the second mounting seat 203 through the flange 208. At this time, each clamping jaw 204 is radially closed under the action of the connecting rod 205, and the movable handle 302 also rotates to its initial position.

[0032] from Figure 3 and Figure 6 It can be seen that the lighting camera mechanism 4 includes a mounting tube 401 sleeved in the telescopic tube, one end of the mounting tube 401 is fixed on the second mounting seat 203, and the other end is provided with a lighting camera lens 402, and the control circuit of the lighting camera lens 402 is also arranged in the mounting tube 401. Preferably, a battery for powering the lighting camera lens 402 can be arranged in the mounting tube 401. Specifically, in order to further facilitate the operation of medical staff, a lens switch 403 is also provided on the fixed handle 301, and the lens switch 403 is connected to the control circuit of the lighting camera lens 402. A display 404 for displaying the image captured by the lighting camera lens 402 is also installed on the fixed handle 301 through a universal joint. A display switch 405 is also provided on the fixed handle 301, and the display switch 405 is connected to the control circuit of the display 404.

[0033] like Figure 5 and Figure 6 As shown, in a specific application scenario, a plurality of support frames 101 are further provided in the flexible interventional catheter 1, and both the second mounting seat 203 and the support frames 101 are provided with threading openings for circuit arrangement and rope threading openings for cable 210 arrangement.

[0034] To sum up, the grasping, lighting and video are integrated into one, which makes it convenient for medical staff to quickly search for foreign objects in the digestive tract during operation. At the same time, the gripping mechanism 3 is used to control the movement of the clamping mechanism 2, which is convenient for medical staff to clamp and remove foreign objects in the digestive tract. The operation is simple, time-saving and labor-saving. The lighting and video mechanism 4 is integrated in the clamping mechanism 2, which makes the device more integrated, which is helpful to reduce the patient's pain during operation, and also makes it convenient for medical staff to align the clamping mechanism 2 with foreign objects in the digestive tract, thereby improving the efficiency of foreign body removal. Under the action of the flexible interventional catheter 1, the clamping mechanism 2 and the lighting and video mechanism 4 can adaptively adjust the angle according to the internal contour of the digestive tract, which is helpful to reduce the risk of secondary damage to the digestive tract.
