Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary device technology, specifically relating to an endoscopic foreign body and tumor removal device. Background Technology

[0002] Gastroscopy is a medical examination method, and can also refer to the instrument used in this examination. Gastroscopy uses a gastroscope tube with an endoscope at the tip. An outer protective sheath is fitted over the gastroscope tube (to prevent the tip of the gastroscope tube from scratching the upper digestive tract). It is inserted through the mouth and can be inserted sequentially into the esophagus, stomach, and duodenum. If there are foreign objects or lesions that need to be removed, endoscopic forceps can be inserted through the auxiliary channel on the gastroscope tube to remove them. Gastroscopy allows direct observation of the actual condition of the examined area, and further diagnoses can be made by performing pathological biopsies and cytological examinations on suspicious lesions. It is the preferred examination method for upper digestive tract diseases.

[0003] Currently, the removal of foreign bodies or round or oval lesions from the upper digestive tract requires the use of endoscopic foreign body forceps. The forceps are inserted into the endoscopic tube to clamp and remove the foreign body. However, the open structure of the forceps does not provide strong containment of the foreign body or lesion, making it easy for the foreign body to fall off during the removal process, resulting in poor usability.

[0004] Based on the above, the present invention proposes an endoscopic foreign body and tumor removal device. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, the present invention provides an endoscopic foreign body and tumor removal device, which can grasp foreign bodies or near-circular lesions. Furthermore, the device can enclose the foreign body or near-circular lesions through a semi-circular grasping sleeve one and a semi-circular grasping sleeve two, making it less likely for the foreign body or near-circular lesions to fall off during the grasping and removal process, thus providing superior performance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an endoscopic foreign body and tumor removal device, comprising a gastroscopy tube, an outer protective tube, and a clamping tube, wherein the outer protective tube is sleeved on the outside of the gastroscopy tube, and the clamping tube is inserted into the inside of the gastroscopy tube;

[0007] A control handle is fixedly connected to the rear end of the gripping tube. A T-shaped screw is screwed into the inside of the control handle. A slider is connected to the front end of the control handle via a rotating shaft, and the slider is slidably connected to the control handle. A main control line is fixedly connected to the front end of the slider, and the front end of the main control line extends into the front end of the gripping tube. Branch line one and branch line two are respectively connected to the two sides of the front end of the main control line.

[0008] A fixed shaft is fixedly connected to the front end of the clamping tube. A first torsion sleeve is fitted onto the upper end of the fixed shaft. A semi-circular clamping sleeve is fixedly connected to the front end of the first torsion sleeve. A second torsion sleeve is fitted onto the bottom end of the fixed shaft. A semi-circular clamping sleeve is fixedly connected to the front end of the second torsion sleeve. Springs are fixedly connected between the rear ends of the first and second torsion sleeves and the inner wall of the clamping tube. Connecting holes are provided at the rear ends of the first and second torsion sleeves. The front end of the first branch line is tied to the connecting hole on the first torsion sleeve. The front end of the second branch line is tied to the connecting hole on the second torsion sleeve. A guide hole sleeve is fixedly connected to the front end of the clamping tube, and the main control line passes through the guide hole sleeve.

[0009] As a preferred technical solution of the endoscopic foreign body and tumor removal device of the present invention, both the semi-circular clamping sleeve one and the semi-circular clamping sleeve two are integrally formed with blades on all four sides.

[0010] As a preferred embodiment of the endoscopic foreign body and tumor removal device of the present invention, the interior of both the semi-circular clamping sleeve one and the semi-circular clamping sleeve two are fixedly connected with several fixed cones.

[0011] As a preferred embodiment of the endoscopic foreign body and tumor removal device of the present invention, the semi-circular clamping sleeve one and the semi-circular clamping sleeve two are symmetrically distributed.

[0012] As a preferred technical solution of the endoscopic foreign body and tumor removal device of the present invention, both the upper and lower ends of the fixed axis are fixedly connected with limit rings, and the distance between the two limit rings is equal to the sum of the heights of the first and second twist sleeves.

[0013] As a preferred technical solution of the endoscopic foreign body and tumor removal device of the present invention, the main control line, branch line one and branch line two are all steel wire components, and the branch line one and branch line two are distributed in a "Y" shape relative to the main control line.

[0014] As a preferred embodiment of the endoscopic foreign body and tumor removal device of the present invention, a number of anti-slip twist strips are fixedly connected around the rear end of the T-shaped screw.

[0015] As a preferred embodiment of the endoscopic foreign body and tumor removal device of the present invention, the control handle is fixedly connected with an anti-slip handle sleeve around its outer periphery, and the anti-slip handle sleeve is a rubber component.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In use, the present invention involves inserting the clamping tube into the auxiliary channel of the endoscope tube. Once the tube reaches the designated position, the control handle opens the semi-circular clamping sleeves one and two to grip the foreign object or a roughly circular lesion. Then, the control handle closes the semi-circular clamping sleeves one and two to enclose the foreign object or roughly circular lesion, which is then removed. This technical solution enables the retrieval of foreign objects or roughly circular lesions. Furthermore, the semi-circular clamping sleeves one and two enclose the foreign object or roughly circular lesion, making it less likely to fall off during retrieval. This method is preferred.

[0018] 2. During use, the opening and closing of the semi-circular clamping sleeve one and the semi-circular clamping sleeve two are controlled by the T-shaped screw at the rear end of the clamping tube engaging with the control handle to drive the main control line to retract and extend. The screw engagement control provides more precise control over the opening and closing size and prevents the sleeve from opening on its own, making the opening and closing control safer. The control effect of the semi-circular clamping sleeve one and the semi-circular clamping sleeve two is better, making it easier to clamp foreign objects or spherical lesions.

[0019] 3. During use, the invention can also cut and separate the lesion tissue from its external tissues through the blades on the semi-circular clamping sleeve one and the semi-circular clamping sleeve two, so as to facilitate the clamping and use of spherical lesion tissues.

[0020] 4. During use, the present invention can also be further fixed by the fixing cone inside the semi-circular clamping sleeve one and the semi-circular clamping sleeve two, making it less likely to fall out, so as to facilitate the clamping and use of foreign objects or lesions.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1-8 The present invention provides the following technical solution: an endoscopic foreign body and tumor removal device, comprising a gastroscopy tube 1, an outer protective tube 2 and a clamping tube 3, wherein the outer protective tube 2 is sleeved on the outside of the gastroscopy tube 1 and the clamping tube 3 is inserted into the inside of the gastroscopy tube 1.

[0035] Furthermore, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a control handle 4 is fixedly connected to the rear end of the gripping tube 3. A T-shaped screw 5 is screwed into the inside of the control handle 4. Several anti-slip twist strips 6 are fixedly connected around the rear end of the T-shaped screw 5. A slider 8 is connected to the front end of the control handle 4 via a pivot 7, and the slider 8 is slidably connected to the control handle 4. A main control line 9 is fixedly connected to the front end of the slider 8, and the front end of the main control line 9 extends into the front end of the gripping tube 3. Branch line 11 and branch line 2 12 are respectively connected to the two sides of the front end of the main control line 9. The main control line 9, branch line 11, and branch line 2 12 are all steel wire components, and branch line 11... 1 and branch line 2 12 are distributed in a "Y" shape relative to the main control line 9. The outer periphery of the control handle 4 is fixedly connected with an anti-slip handle sleeve 10, which is a rubber component. The control handle 4 at the rear end of the clamping tube 3 allows control of the front end structure of the clamping tube 3 from the rear end. The rubber anti-slip handle sleeve 10 on the control handle 4 facilitates the anti-slip grip of the control handle 4. The surface of the anti-slip handle sleeve 10 is integrally formed with anti-slip stripes, which are not specifically shown in the figure. The anti-slip twist strip 6 on the T-shaped screw 5 facilitates the hand-tightening of the T-shaped screw 5.

[0036] Furthermore, refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, a fixed shaft 13 is fixedly connected to the front end of the clamping tube 3. A torsion sleeve 15 is fitted onto the upper end of the fixed shaft 13. A semi-circular clamping sleeve 16 is fixedly connected to the front end of the torsion sleeve 15. A torsion sleeve 2 17 is fitted onto the bottom end of the fixed shaft 13. A semi-circular clamping sleeve 2 18 is fixedly connected to the front end of the torsion sleeve 2 17. The semi-circular clamping sleeves 16 and 2 18 are symmetrically distributed. Both the semi-circular clamping sleeves 16 and 2 18 have integrally formed blades 19 on all four sides. Several fixed cones 20 are fixedly connected inside the semi-circular clamping sleeves 16 and 2 18. Limiting rings 14 are fixedly connected to both the upper and lower ends of the fixed shaft 13, and the distance between the two limiting rings 14 is equal to the sum of the heights of the torsion sleeves 15 and 2 17. The rear ends of the torsion sleeves 15 and 2 17 are connected to the clamping sleeves 18. Springs 21 are fixedly connected to the inner walls of the clamping tube 3. The rear ends of the first twist sleeve 15 and the second twist sleeve 17 are both provided with connecting holes 22. The front end of the first branch line 11 is tied to the connecting hole 22 on the first twist sleeve 15, and the front end of the second branch line 12 is tied to the connecting hole 22 on the second twist sleeve 17. A guide hole sleeve 23 is fixedly connected inside the front end of the clamping tube 3, and the main control line 9 is connected to the guide hole sleeve 23. The upper limit ring 14 of the fixed shaft 13 can limit the upper and lower movement of the first twist sleeve 15 and the second twist sleeve 17 on the fixed shaft 13 to prevent the first twist sleeve 15 and the second twist sleeve 17 from moving up and down relative to the fixed shaft 13, so as to avoid the asymmetry of the upper and lower misalignment of the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28. The guide hole sleeve 23 inside the clamping tube 3 can guide and limit the control movement of the main control line 9.

[0037] In this embodiment, when using the invention, the clamping tube 3 is inserted into the auxiliary channel of the endoscope tube 1. After reaching the designated position, the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 2 18 are opened by the control handle 4 to grip the foreign object or the near-circular lesion tissue. Then, the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 2 18 are closed by the control handle 4 to enclose the foreign object or the near-circular lesion tissue, and then it is taken out. Through the above technical solution, the clamping of foreign objects or near-circular lesions can be achieved. Moreover, the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 2 18 can enclose the foreign object or the near-circular lesion tissue, making it less likely to fall off during the clamping and removal process, which is preferable. In the use of the invention, the opening and closing of the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 2 18 is controlled by the T-shaped screw 5 at the rear end of the clamping tube 3. The control handle 4 is screwed on to drive the main control line 9 to retract and extend for control. It uses a threaded engagement for retraction and extension control, resulting in more precise control of the opening and closing size. It also prevents the line from opening on its own, making the opening and closing control safer. The semi-circular gripping sleeves 16 and 18 provide better control, facilitating the gripping of foreign objects or near-circular lesions. During use, the blades 19 on the semi-circular gripping sleeves 16 and 18 can also cut and separate the lesion from its surrounding tissues, facilitating the gripping of near-circular lesions. Furthermore, the fixing cones 20 inside the semi-circular gripping sleeves 16 and 18 can further assist in fixing the gripped foreign objects or near-circular lesions, making them less likely to fall out, thus facilitating the gripping of foreign objects or near-circular lesions.

[0038] The usage process and working principle of this invention are as follows: When in use, the endoscope tube 1, with the outer protective tube 2 attached to the front end, is inserted into the corresponding position of the upper digestive tract through the mouth. During insertion, the front end of the endoscope tube 1 is retracted into the front end of the outer protective tube 2 to prevent the front end structure of the endoscope tube 1 from scratching the upper digestive tract during insertion. After reaching the corresponding position, the endoscope tube 1 is pushed further relative to the outer protective tube 2 to expose the front end of the endoscope tube 1. Through the above operation, the actual condition of the examined site can be observed, and pathological biopsy and cytological examination of suspicious lesions can be performed to further clarify the diagnosis.

[0039] If there are foreign objects or round lesions inside that need to be removed, insert the clamping tube 3 into the auxiliary channel of the endoscope tube 1, and extend the tip of the clamping tube 3 out of the endoscope tube 1 to the designated position. After reaching the designated position, rotate the T-shaped screw 5 forward relative to the control handle 4 through the anti-slip twist strip 6, and further push the slider 8 forward through the rotating shaft 7. The main control line 9 is in a loose state, and under the elastic force of the spring 21, the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28 open outward on their own. Then, the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28 bite the foreign object or round lesion. Through the blade 19 on the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28, the lesion can be cut and separated from its external tissues. At the same time, the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28 can also be used to remove the foreign object or round lesion. The fixing cone 20 on the second sleeve 18 can assist in fixing foreign objects or near-circular lesions held by the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 2 18. Then, the anti-slip twist strip 6 rotates the T-shaped screw 5 backward relative to the control handle 4, and further drives the slider 8 to move backward through the rotating shaft 7. The main control line 9 is in a taut state, and the branch line 11 and the branch line 22 further drive the twist sleeve 15 and the twist sleeve 27 to rotate relative to the fixed axis 13. The spring 21 is stretched, thereby controlling the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 2 18 to close. Then, the endoscope tube 1 and the clamping tube 3 can be pulled back relative to the outer protective tube 2, so that the front end of the endoscope tube 1 and the clamping tube 3 are retracted into the outer protective tube 2. Then they can be taken out together. The above operation can be performed by two or more people.

[0041] Example 2

[0042] Please see Figure 1-9 The present invention provides the following technical solution: an endoscopic foreign body and tumor removal device, comprising a gastroscopy tube 1, an outer protective tube 2 and a clamping tube 3, wherein the outer protective tube 2 is sleeved on the outside of the gastroscopy tube 1 and the clamping tube 3 is inserted into the inside of the gastroscopy tube 1.

[0043] Furthermore, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a control handle 4 is fixedly connected to the rear end of the gripping tube 3. A T-shaped screw 5 is screwed into the inside of the control handle 4. Several anti-slip twist strips 6 are fixedly connected around the rear end of the T-shaped screw 5. A slider 8 is connected to the front end of the control handle 4 via a pivot 7, and the slider 8 is slidably connected to the control handle 4. A main control line 9 is fixedly connected to the front end of the slider 8, and the front end of the main control line 9 extends into the front end of the gripping tube 3. Branch line 11 and branch line 2 12 are respectively connected to the two sides of the front end of the main control line 9. The main control line 9, branch line 11, and branch line 2 12 are all steel wire components, and branch line 11... 1 and branch line 2 12 are distributed in a "Y" shape relative to the main control line 9. The outer periphery of the control handle 4 is fixedly connected with an anti-slip handle sleeve 10, which is a rubber component. The control handle 4 at the rear end of the clamping tube 3 allows control of the front end structure of the clamping tube 3 from the rear end. The rubber anti-slip handle sleeve 10 on the control handle 4 facilitates the anti-slip grip of the control handle 4. The surface of the anti-slip handle sleeve 10 is integrally formed with anti-slip stripes, which are not specifically shown in the figure. The anti-slip twist strip 6 on the T-shaped screw 5 facilitates the hand-tightening of the T-shaped screw 5.

[0044] Furthermore, refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a fixed shaft 13 is fixedly connected inside the front end of the clamping tube 3. A first twist sleeve 15 is fitted onto the upper end of the fixed shaft 13. A semi-circular clamping sleeve 16 is fixedly connected to the front end of the first twist sleeve 15. A second twist sleeve 17 is fitted onto the bottom end of the fixed shaft 13. A second semi-circular clamping sleeve 18 is fixedly connected to the front end of the second twist sleeve 17. The first and second semi-circular clamping sleeves 16 and 18 are symmetrically distributed. Both the first and second semi-circular clamping sleeves 16 and 18 have integrally formed blades 19 on all four sides. Several crescent-shaped clamping plates 24 are fixedly connected inside the first and second semi-circular clamping sleeves 16 and 18. Limiting rings 14 are fixedly connected to both the upper and lower ends of the fixed shaft 13, and the distance between the two limiting rings 14 is equal to the sum of the heights of the first twist sleeve 15 and the second twist sleeve 17. The rear ends of the first twist sleeve 15 and the second twist sleeve 17 are connected to... Springs 21 are fixedly connected to the inner walls of the clamping tube 3. The rear ends of the first twist sleeve 15 and the second twist sleeve 17 are provided with connecting holes 22. The front end of the first branch line 11 is tied to the connecting hole 22 on the first twist sleeve 15, and the front end of the second branch line 12 is tied to the connecting hole 22 on the second twist sleeve 17. A guide hole sleeve 23 is fixedly connected inside the front end of the clamping tube 3, and the main control line 9 is connected to the guide hole sleeve 23. The upper limit ring 14 of the fixed shaft 13 can limit the upper and lower movement of the first twist sleeve 15 and the second twist sleeve 17 on the fixed shaft 13 to prevent the first twist sleeve 15 and the second twist sleeve 17 from moving up and down relative to the fixed shaft 13, so as to avoid the asymmetry of the upper and lower misalignment of the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28. The guide hole sleeve 23 inside the clamping tube 3 can guide and limit the control movement of the main control line 9.

[0045] In this embodiment, during use, the clamping tube 3 is inserted into the auxiliary channel of the endoscope tube 1. Once it reaches the designated position, the control handle 4 controls the opening of the semi-circular clamping sleeves 16 and 18 to grip the foreign object or a roughly circular lesion. Then, the control handle 4 controls the closing of the semi-circular clamping sleeves 16 and 18 to enclose the foreign object or roughly circular lesion, which is then removed. Through this technical solution, the clamping of foreign objects or roughly circular lesions can be achieved, and the semi-circular... The first clamping sleeve 16 and the second semi-circular clamping sleeve 18 can enclose foreign objects or near-circular lesions, making them less likely to fall off during the clamping and removal process, thus providing superior performance. During use, the opening and closing of the first semi-circular clamping sleeve 16 and the second semi-circular clamping sleeve 18 is controlled by the T-shaped screw 5 at the rear end of the clamping tube 3 engaging with the control handle 4, thereby driving the main control line 9 to retract and extend. This threaded engagement control provides more precise control over the opening and closing size and prevents the sleeve from opening on its own, making the opening and closing control safer. The semi-circular gripping sleeve 16 and semi-circular gripping sleeve 2 18 provide better control, facilitating the gripping of foreign objects or roughly circular lesions. During use, the blades 19 on the semi-circular gripping sleeves 16 and 18 can also cut and separate the lesion from its surrounding tissues, further facilitating the gripping of roughly circular lesions. Furthermore, the crescent-shaped clamping plates 24 within the semi-circular gripping sleeves 16 and 18 can further enhance the occlusal engagement. The foreign objects or near-circular lesions are further secured to make them less likely to fall out, thus facilitating their removal. In this embodiment, the crescent-shaped clamping plate 24 inside the semi-circular clamping sleeve 16 and semi-circular clamping sleeve 28 has a larger contact surface with the object compared to the fixing cone 20 inside the semi-circular clamping sleeve 16 and semi-circular clamping sleeve 28 in embodiment 1, resulting in better auxiliary fixation of the foreign objects. However, the internal space of the semi-circular clamping sleeve 16 and semi-circular clamping sleeve 28 is reduced.

[0046] The usage process and working principle of this invention are as follows: When in use, the endoscope tube 1, with the outer protective tube 2 attached to the front end, is inserted into the corresponding position of the upper digestive tract through the mouth. During insertion, the front end of the endoscope tube 1 is retracted into the front end of the outer protective tube 2 to prevent the front end structure of the endoscope tube 1 from scratching the upper digestive tract during insertion. After reaching the corresponding position, the endoscope tube 1 is pushed further relative to the outer protective tube 2 to expose the front end of the endoscope tube 1. Through the above operation, the actual condition of the examined site can be observed, and pathological biopsy and cytological examination of suspicious lesions can be performed to further clarify the diagnosis.

[0047] If there are foreign objects or round or oval lesions inside the endoscope tube that need to be removed, insert the clamping tube 3 into the auxiliary channel of the endoscope tube 1, and extend the tip of the clamping tube 3 out of the endoscope tube 1 to the designated position. After reaching the designated position, rotate the T-shaped screw 5 forward relative to the control handle 4 through the anti-slip twist strip 6, and further push the slider 8 forward through the rotating shaft 7. The main control line 9 is in a loose state, and under the elastic force of the spring 21, the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28 open outward on their own. Then, the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28 bite the foreign object or round or oval lesion. Through the blade 19 on the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28, the lesion can be cut and separated from its external tissues. At the same time, the semi-circular clamping sleeve 16 and the semi-circular clamping sleeve 28 can also be used to remove the foreign object or round or oval lesion. The crescent-shaped clamp 24 on sleeve 2 18 can assist in fixing foreign objects or near-circular lesions held by the semi-circular clamping sleeve 1 16 and the semi-circular clamping sleeve 2 18. Then, the anti-slip twist strip 6 rotates the T-shaped screw 5 backward relative to the control handle 4, and further drives the slider 8 to move backward through the rotating shaft 7. The main control line 9 is in a taut state, and the branch line 1 11 and the branch line 2 12 further drive the twist sleeve 1 15 and the twist sleeve 2 17 to rotate relative to the fixed axis 13. The spring 21 is stretched, thereby controlling the semi-circular clamping sleeve 1 16 and the semi-circular clamping sleeve 2 18 to close. Then, the endoscope tube 1 and the clamping tube 3 can be pulled back relative to the outer protective tube 2, so that the front end of the endoscope tube 1 and the clamping tube 3 are retracted into the outer protective tube 2. Then they can be taken out together. When performing the above operations, two or more people can operate together.
