Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a device for removing foreign objects in the body. Background Art

[0002] Many patients often accidentally swallow various foreign objects. Especially children have a relatively poor pharyngeal reflex and incomplete molarization, making it easier to swallow foreign objects. When a patient accidentally swallows a foreign object, the traditional solution is to use a foreign object forceps to remove the foreign object in the patient's gastrointestinal tract.

[0003] However, since it is impossible to judge the shape and material of the foreign object from the patient's description, doctors can only choose a foreign object forceps for the operation based on experience. If the forceps head of the foreign object forceps is not suitable, they can only try another foreign object forceps, which prolongs the operation time, increases the patient's pain, and is not conducive to the treatment of the patient. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present invention provides a device for removing foreign objects in the body. Through an endoscope, the shape and material of the foreign object in the patient's body can be clearly shown. The doctor selects a suitable foreign object forceps for clamping the foreign object by rotating the foreign object forceps selection ring; by manipulating the direction adjustment rod to pull the steel cable, the steel cable drags the head of the pipeline to rotate, which is convenient for the doctor to observe the foreign object in the patient's body and is conducive to operating the foreign object forceps to remove the foreign object, and controls the selected foreign object forceps by manipulating the finger handle to remove the foreign object in the patient's body, effectively solving the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a device for removing foreign objects in the body, including basic components, a manipulation assembly, a flexible pipeline, and a pipeline head. The manipulation assembly is arranged at the upper end of the flexible pipeline, the pipeline head is arranged at the lower end of the flexible pipeline, and the basic components are arranged inside the flexible pipeline; the basic components include a steel cable, a flexible traction rod, an endoscope, and a foreign object forceps assembly. The steel cable is arranged in the steel cable channel of the flexible pipeline, the flexible traction rod is arranged in the traction rod channel of the flexible pipeline, the flexible traction rod includes a traction inner rod and a traction sleeve, and the traction inner rod is arranged inside the traction sleeve.

[0010] Furthermore, the operating assembly also includes a direction adjustment rod, a finger handle, an elastic pressure piece and a foreign body forceps selection ring, the direction adjustment rod is arranged in the direction adjustment part, the finger handle is arranged on the foreign body forceps control part, the elastic pressure piece is arranged in the positioning telescopic hole, and the foreign body forceps selection ring is arranged on the annular groove of the foreign body forceps control part.

[0011] Furthermore, the direction adjustment rod is provided with a universal seat, a triangle plate and a toggle column, the universal seat is arranged on the universal head support, the steel rope is connected to the three corners of the triangle plate, and the toggle column is arranged on the shaping elastic sheet.

[0012] Preferably, the doctor manipulates the toggle column with his fingers to rotate and tilt the direction adjustment rod on the universal head support, and then the triangle plate pulls the steel rope, and the steel rope pulls the pipe head to rotate, which is convenient for the doctor to observe foreign bodies in the patient's body and facilitates the operation of foreign body forceps to remove foreign bodies. At the same time, the shaping elastic sheet at the top of the direction adjustment part can fix the inclination angle of the toggle column.

[0013] Furthermore, the finger handle is provided with a sliding plate, the sliding plate is arranged on the top of the elastic pressure piece, the sliding plate is arranged on the central positioning column, and the finger handle slides in the sliding groove.

[0014] Furthermore, the elastic pressure piece is provided with an upper spring plate, a lower spring plate, a downward pressure spring and an inner rod spring, the upper end of the downward pressure spring is provided on the upper spring plate, the lower end of the downward pressure spring is provided on the lower spring plate, a positioning hole is provided on the outer wall of the lower spring plate, an inner rod spring is provided on the lower side of the downward pressure spring, and the bottom of the inner rod spring is provided on the traction inner rod.

[0015] Preferably, when the finger handle is operated to move downward, the sliding plate presses down the elastic pressure piece, and the elastic pressure piece will push the flexible traction rod to move, thereby pushing the foreign body clamp out of the foreign body clamp channel at the pipe head, and the inner rod spring on the lower side of the elastic pressure piece will further squeeze and pull the inner rod, and the pulling inner rod will control the clamp head of the foreign body clamp to unfold; when the finger handle is moved upward, the sliding plate of the finger handle drives the elastic pressure piece to move upward, and the lower spring plate does not generate pulling force on the traction sleeve, and the traction sleeve maintains the state of pushing out the foreign body clamp under the friction force of the flexible pipe, but the inner rod spring at the bottom of the lower spring plate is connected to pull the inner rod upward, and then the pulling inner rod will first control the clamp head of the foreign body clamp to close, and then drive the foreign body clamp to move upward, and the foreign body clamp pushes the traction sleeve to move upward, thereby achieving the technical effect of the doctor controlling the foreign body clamp to clamp the foreign body by operating the finger handle.

[0016] Furthermore, the foreign object forceps selection ring is provided with a fixing pin, a fixing pin spring and a locking pin. The fixing pin spring is arranged in two holes inside the foreign object forceps selection ring, and the locking pin is arranged on the outer wall of the foreign object forceps selection ring. The fixing pin and the hole in which the fixing pin spring is placed are distributed in a regular triangle, and the fixing pin is arranged on the fixing pin spring.

[0017] Furthermore, the fixing pin is arranged in the positioning hole, and the locking pin is located above the locking groove on the outer wall of the foreign body clamp operating part.

[0018] Preferably, when the fixing pin of the foreign body forceps selection ring is in the positioning hole of the lower spring plate, the downward movement of the upper spring plate can only compress the lower pressure spring and will not push the lower spring plate to move. The two fixing pins on the foreign body forceps selection ring will block the lower spring plates of the two elastic pressure pieces, thereby achieving the technical effect that only one foreign body forceps can be manipulated by the finger handle at the same time. At the same time, the elastic pressure pieces fixed by the fixing pins are different due to the different angles of the foreign body forceps selection ring, thereby achieving the technical effect that the doctor can observe the shape and material of the foreign body through the endoscope and rotate the foreign body forceps selection ring to select the appropriate foreign body forceps.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The endoscope can clearly display foreign bodies in the patient's body. Doctors can choose the appropriate foreign body forceps to remove foreign bodies from the three types of foreign body forceps: unilateral foreign body forceps, bilateral foreign body forceps and net bag foreign body forceps, according to the shape and material of the foreign bodies. This effectively solves the technical problem that doctors can only choose foreign body forceps based on experience.

[0020] 2. The doctor manipulates the toggle column with his fingers to make the direction adjustment rod rotate and tilt on the universal head support, and then the triangle plate pulls the steel rope, and the steel rope pulls the pipe head to rotate, which is convenient for the doctor to observe foreign bodies in the patient's body and facilitates the operation of foreign body forceps to remove foreign bodies. At the same time, the shaping elastic sheet at the top of the direction adjustment part can fix the inclination angle of the toggle column.

[0021] 3. When the manipulation finger handle moves downward, the sliding plate presses down the elastic pressure member. The elastic pressure member will push the flexible traction rod to move, thereby pushing the foreign object forceps out of the foreign object forceps channel at the head of the pipeline. Moreover, the inner rod spring on the lower side of the elastic pressure member will further squeeze the traction inner rod, and the traction inner rod controls the expansion of the jaws of the foreign object forceps. When the finger handle moves upward, the sliding plate of the finger handle drives the elastic pressure member to move upward. The lower spring plate does not exert a pulling force on the traction sleeve. The traction sleeve maintains the state of pushing out the foreign object forceps under the action of the friction force of the flexible pipeline. However, the inner rod spring at the bottom of the lower spring plate connects the traction inner rod to move upward. Consequently, the traction inner rod will first control the jaws of the foreign object forceps to close, and then drive the foreign object forceps to move upward. The foreign object forceps push the traction sleeve upward, achieving the technical effect that the doctor can control the foreign object forceps to pick up foreign objects by manipulating the finger handle.

[0022] 4. When the fixing pin of the foreign object forceps selection ring is in the positioning hole of the lower spring plate, when the upper spring plate moves downward, it can only compress the lower pressure spring and will not push the lower spring plate to move. The two fixing pins on the foreign object forceps selection ring will block the lower spring plates of the two elastic pressure members, achieving the technical effect that the finger handle can only manipulate one foreign object forceps at the same time. Meanwhile, with different rotation angles of the foreign object forceps selection ring, different elastic pressure members are fixed by the fixing pins, achieving the technical effect that the doctor can rotate the foreign object forceps selection ring to select a suitable foreign object forceps according to the shape and material of the foreign object observed by the endoscope.

[0031] The upper end of the manipulation assembly 2 is a direction adjustment part 21, the lower end of the manipulation assembly 2 is a foreign object clamp control part 22, the bottom of the foreign object clamp control part 22 is connected to the flexible pipeline 3, the top of the direction adjustment part 21 is provided with a shaped elastic sheet 211, and inside the direction adjustment part 21 there are a universal joint support 212 and an optical cable protection column 213, and the universal joint support 212 is arranged at the upper end of the optical cable protection column 213.

[0032] The foreign object clamp control part 22 is internally provided with positioning telescopic holes 221 distributed in an equilateral triangle, the upper half of the foreign object clamp control part 22 is provided with a central positioning column 222 and a sliding groove 223, and the outer wall of the foreign object clamp control part 22 is provided with an annular groove and a locking groove.

[0033] The operating assembly 2 also includes a direction adjustment rod 23, a finger handle 24, an elastic pressure piece 25 and a foreign body forceps selection ring 26. The direction adjustment rod 23 is arranged in the direction adjustment part 21, the finger handle 24 is arranged on the foreign body forceps operating part 22, the elastic pressure piece 25 is arranged in the positioning telescopic hole 221, and the foreign body forceps selection ring 26 is arranged on the annular groove of the foreign body forceps operating part 22.

[0034] The direction adjustment rod 23 is provided with a universal seat 231 , a triangular plate 232 and a toggle post 233 . The universal seat 231 is arranged on the universal head support 212 . The steel rope 11 is connected to the three corners of the triangular plate 232 . The toggle post 233 is arranged on the shaping elastic sheet 211 .

[0035] The doctor manipulates the toggle column 233 with his fingers to rotate and tilt the direction adjustment rod 23 on the universal head support 212, and then the triangle plate 232 pulls the steel rope 11, and the steel rope 11 pulls the pipe head 4 to rotate, which is convenient for the doctor to observe foreign bodies in the patient's body and is conducive to operating the foreign body forceps to remove foreign bodies. At the same time, the shaping elastic sheet 211 at the top of the direction adjustment part 21 can fix the tilt angle of the toggle column 233.

[0036] The finger handle 24 is provided with a sliding plate 241 . The sliding plate 241 is arranged on the top of the elastic pressure member 25 . The sliding plate 241 is arranged on the central positioning column 222 . The finger handle 24 slides in the sliding groove 223 .

[0037] The elastic pressure member 25 is provided with an upper spring plate 251, a lower spring plate 252, a downward pressure spring 253 and an inner rod spring 254. The upper end of the downward pressure spring 253 is arranged on the upper spring plate 251, and the lower end of the downward pressure spring 253 is arranged on the lower spring plate 252. A positioning hole 2521 is arranged on the outer wall of the lower spring plate 252. The lower side of the downward pressure spring 253 is provided with an inner rod spring 254, and the bottom of the inner rod spring 254 is arranged on the traction inner rod 121.

[0038] Among them, when the finger handle 24 is operated to move downward, the sliding plate 241 presses down the elastic pressure piece 25, and the elastic pressure piece 25 will push the flexible traction rod 12 to move, thereby pushing the foreign body clamp out of the foreign body clamp channel of the pipe head 4, and the inner rod spring 254 on the lower side of the elastic pressure piece 25 will further squeeze and pull the inner rod 121, and the pulling inner rod 121 controls the chuck of the foreign body clamp to unfold; when the finger handle 24 moves upward, the sliding plate 241 of the finger handle 24 drives the elastic pressure piece 25 to move upward, and the lower spring plate 252 does not generate pulling force on the traction sleeve 122. The traction sleeve 122 maintains the state of pushing out the foreign body clamp under the friction force of the flexible pipe 3, but the inner rod spring 254 at the bottom of the lower spring plate 252 is connected to the pulling inner rod 121 to move upward, and then the pulling inner rod 121 will first control the chuck of the foreign body clamp to close, and then drive the foreign body clamp to move upward, and the foreign body clamp pushes the traction sleeve 122 to move upward, thereby achieving the technical effect of the doctor controlling the foreign body clamp to clamp the foreign body by operating the finger handle 24.

[0039] The foreign body forceps selection ring 26 is provided with a fixing pin 261, a fixing pin spring 262 and a locking pin 263. The fixing pin spring 262 is arranged in two holes inside the foreign body forceps selection ring 26, and the locking pin 263 is arranged on the outer wall of the foreign body forceps selection ring 26. The fixing pin 261 and the hole for placing the fixing pin spring 262 are distributed in a regular triangle, and the fixing pin 261 is arranged on the fixing pin spring 262.

[0040] The fixing pin 261 is disposed in the positioning hole 2521 , and the locking pin 263 is located above the locking groove on the outer wall of the foreign body forceps operating part 22 .

[0041] Among them, when the fixing pin 261 of the foreign body forceps selection ring 26 is in the positioning hole 2521 of the lower spring plate 252, the upper spring plate 251 moves downward and can only compress the lower pressure spring 253 but will not push the lower spring plate 252 to move. The two fixing pins 261 on the foreign body forceps selection ring 26 will block the lower spring plates 252 of the two elastic pressure pieces 25, thereby achieving the technical effect that the finger handle 24 can only manipulate one foreign body forceps at the same time. At the same time, when the foreign body forceps selection ring 26 is rotated at different angles, the elastic pressure pieces 25 fixed by the fixing pin 261 are different, thereby achieving the technical effect that the doctor observes the shape and material of the foreign body through the endoscope 13 and rotates the foreign body forceps selection ring 26 to select the appropriate foreign body forceps.

[0042] During specific use, the pipe head 4 is inserted into the patient's body, the shape and material of the foreign body in the patient's body are observed through the endoscope 13, the foreign body forceps selection ring 26 is rotated, and a suitable foreign body forceps is selected. During the foreign body forceps selection ring 26 process, the arc-shaped side wall of the fixing pin 261 is squeezed by the side wall of the positioning hole 2521, and then the fixing pin 261 compresses the fixing pin spring 262 and is received into the side wall channel of the foreign body forceps selection ring 26. As the foreign body forceps selection ring 26 rotates, the fixing pin 261 is fixed in the next positioning hole 2521, and the lower spring plates 252 of the two elastic pressure pieces 25 are blocked by the fixing pin 261, and the locking pin 263 of the foreign body forceps selection ring 26 slides down, so that the locking pin 263 slides into the locking groove outside the foreign body forceps control part 22, so that the foreign body forceps selection ring 26 is fixed.

[0043] During the operation, the doctor controls the rotation of the pipe head 4 by continuously rotating the toggle column 233 of the direction adjustment rod 23. During the operation, the shaping elastic sheet 211 on the top of the direction adjustment part 21 will fix the inclination of the toggle column 233, and the universal seat 231 of the direction adjustment rod 23 rotates on the universal head support 212. At the same time, the raised side of the triangle plate 232 pulls the steel rope 11, and the steel rope 11 pulls the pipe head 4 to bend it.

[0044] The doctor controls the foreign body forceps at the head 4 of the pipeline by moving the finger handle 24 up and down. When the doctor manipulates the finger handle 24 to move downward, the sliding plate 241 of the finger handle 24 presses down the upper spring plate 251 at the top of the elastic pressure member 25. The upper spring plate 251 moves downward to compress the lower pressure spring 253. The lower spring plate 252 that is not fixed by the fixing pin 261 moves downward under the elastic force of the lower pressure spring 253 and pushes the traction sleeve 122 to move. At the same time, the inner rod spring 254 at the bottom of the lower spring plate 252 will first squeeze the traction inner rod 121, and the jaws of the foreign body forceps cannot be unfolded due to being squeezed by the foreign body forceps channel. Therefore, when the flexible traction rod 12 pushes the foreign body forceps out of the foreign body forceps channel for the first time, the inner rod spring 254 pushes the jaws of the foreign body forceps to unfold. When the finger handle 24 moves upward, the sliding plate 241 of the finger handle 24 drives the elastic pressure member 25 to move upward. The upper spring plate 251 drives the lower pressure spring 253 to move upward, and the lower pressure spring 253 drives the lower pressure spring 253 to move upward. Since the lower spring plate 252 does not exert a pulling force on the traction sleeve 122, the traction sleeve 122 remains in the state of pushing out the foreign body forceps under the frictional force of the flexible pipeline 3. However, the inner rod spring 254 at the bottom of the lower spring plate 252 will drive the traction inner rod 121 to move upward following the movement of the lower spring plate 252. Thus, the traction inner rod 121 will first manipulate the jaws of the foreign body forceps to close. As the height of the upward movement of the finger handle 24 increases, the traction inner rod 121 drives the foreign body forceps to move upward, and the foreign body forceps push the traction sleeve 122 to move upward. The doctor controls the distance of the movement of the finger handle 24 to control the foreign body forceps on the head 4 of the pipeline to clamp the foreign body in the patient's body and pull it out of the patient's body.
