Description

Technical Field

[0001] The utility model relates to the field of physical therapy instruments, and more specifically to a controllable magnetic forceps for foreign bodies in children's digestive tract. Background Art

[0002] Currently, endoscopists use forceps, five-claw forceps, snares, and other instruments to remove foreign bodies from the digestive tract. However, removing foreign bodies through the cardia or esophagus can easily cause physiological stenosis, which can lead to re-dislodgement and secondary injury, prolonging treatment time and increasing patient pain. Children are particularly prone to swallowing foreign bodies, which can lead to foreign bodies in the digestive tract. Long-term treatment and secondary dislodgement increase the difficulty and risk of treatment for children. Therefore, there is an urgent need for a digestive tract foreign body forceps that can quickly and effectively remove foreign bodies without causing them to dislodge. Utility Model Content

[0021] The technical solution of the present utility model is further described below through specific embodiments.

[0022] Example 1

[0023] A controllable magnetic forceps for children's digestive tract foreign body includes an operating device 1, a connecting wire 2, an end magnetizing fixing device 3 and a clamping end 4. The operating device 1 is connected to the end magnetizing fixing device 3 through the connecting wire 2. The clamping end 4 is arranged on the end magnetizing fixing device 3 to achieve fixation and magnetization of the clamping end 4. The operating device 1 includes a steel cable control device 5, an electromagnetic control device 6 and a wire connecting part 7. A steel cable 8 and a soft magnetic wire 9 are provided in the connecting wire 2. The steel cable 8 passes through the wire connecting part 7 and is connected to the steel cable control device 5 and the clamping end 4. The soft magnetic wire 9 is connected to the electromagnetic control device 6 and the end magnetizing fixing device 3 through the wire connecting part 7.

[0024] The working principle of this technical solution is as follows: among various foreign bodies in the digestive tract of children, metal foreign bodies account for 20%-50% of the total, including coins, metal needles / nails, magnetic beads and other common problems. A magnetized clamping end 4 is used to control the end magnetization fixing device 3 and the clamping end 4 through the steel cable control device 5 and the electromagnetic control device 6 respectively, and the size of the magnetic force and the action of the clamping end 4 to clamp the foreign body are adjusted to achieve the clamping of the foreign body.

[0025] The steel cable control device 5 includes a handle 10 , a pull rod 11 and a pull ring 12 . The pull rod 11 is provided in the handle 10 , and the pull ring 12 is connected to the steel cable 8 through the pull rod 11 to achieve control of the clamping end 4 .

[0026] The clamping action of the clamping end 4 is controlled by the pull ring 12 and the pull rod 11.

[0027] The electromagnetic control device 6 includes an electromagnetic control housing 13, a power input terminal 14 and a power control switch 15. The power input terminal 14 and the power control switch 15 are provided in the electromagnetic control housing 13. The power input terminal 14 is connected to the soft magnetic wire 9 through the power control switch 15 to realize the control of the current size.

[0028] The power control switch 15 can be a commercially available power regulating switch, which mainly controls the current. Preferably, a rotary switch such as LW12-16D0724 / 3 or other universal transfer switches with similar functions are used, preferably a small and light switch for ease of use.

[0029] The connecting wire 2 is provided with a steel cable lumen 16 and a soft magnetic wire lumen 17, in which the steel cable 8 and the soft magnetic wire 9 are disposed, respectively. The width of the connecting wire 2 should generally be less than 2.8 mm, and the maximum width can be controlled to be less than 3.2 mm. Because the channel of the endoscope forceps currently in circulation is 2.8 mm, the equipment with a 3.2 mm channel needs to be purchased separately, which increases the cost. A connecting wire 2 with a size of more than 3.2 mm will affect its versatility, so a width of less than 2.8 mm is optimal.

[0030] An insulating layer 30 is provided outside the soft magnetic wire 9 to avoid potential safety hazards caused by wire exposure.

[0031] The end magnetizing fixing device 3 includes an end connecting body 18 and a magnetizing device 19. A connecting groove 20 is provided in the end connecting body 18. The connecting groove 20 matches the clamping end 4 to achieve the fixation of the clamping end 4. A plurality of steel cable connection holes 21 are provided on the end connecting body 18. The steel cable 8 is connected to the clamping end 4 through the steel cable connection holes 21. The magnetizing device 19 includes a magnetizer 22 and an insulating shell 23. The magnetizer 22 is arranged in the insulating shell 23. A soft magnetic wire 9 is wound around the magnetizer 22 to generate magnetic force.

[0032] The clamping end 4 includes a connecting base 24 and a clamping head 25 . The clamping head 25 is arranged on the connecting base 24 . The connecting base 24 matches the connecting groove 20 to achieve a fixed connection.

[0033] By connecting the base 24 and the connecting groove 20, the end magnetizing fixing device 3 can be applied to various types of clamping ends 4 such as toothed chucks, five-claw chucks, annular chucks and mesh chucks, etc., to avoid being applied to a single type of clamping end 4. The setting of the steel cable connecting through hole 21 is carried out according to the needs of the terminal 4. Since the connection positions of the clamping ends 4 with different shapes and the steel cable 8 are different, multiple through holes should be set for easy use.

[0034] The connection base 24 is connected to the connection groove 20 by a screw thread fixing method. The screw thread fixing method is simple, firm and easy to use.

[0035] The chuck 25 includes a first clip 26 and a second clip 27, which are hingedly connected by a pin. The first and second clips 26, 27 have the same structure and are both provided with a gripping groove 28. Because foreign objects often have relatively sharp portions, the gripping groove 28 can block these sharp ends during gripping, reducing the possibility of scratches. Furthermore, because the chuck 25 itself is magnetic, the gripping groove 28 also makes it easier to grip and secure foreign objects.

[0036] The first clamping piece 26 and the second clamping piece 27 are both provided with clamping teeth 29 to increase friction and shear stress, making it easier to clamp.

[0037] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0038] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
