Referring to Figures 1, 2, 3, and 4, the present invention is a magnetic quick-release device for electric burning appliances of endoscopes, which includes: a first sleeve 10 having a first A working end surface 10A, a first magnetic end surface 10B, and a first conductive portion 10C; the first working end surface 10A has a concave portion 11, the concave portion 11 is used to correspond to a connecting protrusion of an electric burning appliance 90 91; the first magnetic end surface 10B has a magnetically attractive recess 12; the first conductive portion 10C penetrates the first sleeve portion 10, and can electrically connect the connecting protrusion 91 and the first magnetic end surface 10B .

A second sleeved portion 20 has a second working end surface 20A, a second magnetic attraction end surface 20B, and a second conductive portion 20C; the second working end surface 20A has a protruding portion 21, the protruding portion 21 Is used to correspond to a connecting recess 92 of the electric burning appliance 90; the second magnetic end face 20B has a magnetically attractive convex portion 22; the second conductive portion 20C penetrates the second sleeve portion 20, and can be electrically connected The connecting recess 92 and the second magnetic end surface 20B are sexually connected.

Thereby, when the first magnetic attraction end surface 10B and the second magnetic attraction end surface 20B are relatively in contact, the magnetic attraction concave portion 12 and the magnetic attraction convex portion 22 are attracted and fixed to each other, so that the first sleeve portion 10 and the The second sleeve portion 20 achieves a magnetically attracted relative connection (quick release device), and the first conductive portion 10C and the second conductive portion 20C are electrically connected.

In practice, the simple position interchange of the magnetically attracted concave portion 12 and the magnetically attracted convex portion 22 does not deviate from the scope of protection of this case.

The magnetically attracted concave portion 12 may include a first annular groove 121 and a first annular magnetic member 122; the first annular groove 121 is recessed in the first magnetic end surface 10B, and the first annular The magnetic member 122 is recessed in the first annular groove 121.

The magnetically attracted convex portion 22 corresponds to the magnetically attracted concave portion 12, and may include a second annular groove 221 and a second annular magnetic member 222; the second annular groove 221 is recessed on the second magnetically attracted end surface 20B, the second annular magnetic member 222 is protruded on the second annular groove 221.

In addition, the first annular groove 121 and the first annular magnetic member 122 are coaxial with the first sleeve portion 10; the second annular groove 221 and the second annular magnetic member 222 are connected with the second The sleeve 20 is coaxial.

By means of the convex and concave corresponding and contacting of the second annular magnetic member 222 and the first annular magnetic member 122, the first sleeve portion 10 and the second sleeve portion 20 can be magnetically guided and quickly connected and fixed coaxially (As long as it is greater than the magnetic force, it can be quickly disassembled).

One of the first annular magnetic member 122 and the second annular magnetic member 222 may be a magnet.

The other of the first annular magnetic member 122 and the second annular magnetic member 222 may be a magnetically attractable member.

The electric burning appliance 90 can be a well-known electric burning knife (with a power supply device 70, the electric burning operation can be performed).

The key point of the present invention is that in the actual electrocautery operation, it may not only perform electrocautery, but may also include resection operation, intracavity inspection with endoscope 80 (refer to Figure 5), ..., and other related processes, so that During the operation, the connecting recess 92 may be repeatedly installed and removed from the electric cautery device 90 due to repeated operations. In view of this part, the present invention is provided with the first sleeve portion 10 and the second sleeve portion 20 respectively. The first sleeve portion 10 corresponds to the connecting protrusion 91 of the electric burning appliance 90, and the concave portion 11 is provided. , For socketing and fixing the connecting protrusion 91. The second sleeve portion 20 corresponds to the connecting recess 92 of the electric burning appliance 90, and the protruding portion 21 is provided for inserting and fixing the connecting recess 92. With this design, when the first magnetic attraction end surface 10B and the second magnetic attraction end surface 20B are in relative contact, even if there is no alignment, the magnetic attraction concave portion 12 and the magnetic attraction convex portion 22 can still pass through the opposite Magnetic Guide, and can be pulled by the magnetic force to guide the positive position, and when the magnetically attracted concave portion 12 and the magnetically attracted convex portion 22 are relatively positively guided and magnetically engaged, it is actually achieved that the connecting convex post 91 and the connecting concave seat 92 Magnetic attraction quickly connects the fixed person.

Of course, when you want to detach, it can be quickly detached and detached with a force greater than the magnetic attraction, which is quite convenient.

The advantages and effects of the present invention can be summarized as follows:

[1] The magnetic quick release is quite convenient. According to the present invention, a first sleeve portion and a second sleeve portion are respectively provided on the connecting protrusion and the connecting recess of the electric burning appliance, and then the first sleeve portion and the second sleeve portion can be relatively magnetically attracted It can be connected and fixed (or separated and disassembled), no screw lock or tenon is required at all, which is quite convenient. Therefore, the magnetic quick release is quite convenient.

[2] Magnetic guidance does not require self-correction. When the first magnetic end face is in relative contact with the second magnetic end face, even if there is no alignment, it can still be guided by the relative magnetic attraction between the magnetically attracted concave portion and the magnetically attracted convex portion, and can be guided by the magnetic attraction. The magnetic force pulls the positive guiding position, so that the magnetically attracted concave portion and the magnetically attracted convex portion are relatively positively guided and magnetically engaged. Therefore, the magnetic guidance does not need to correct itself.

The above is only a detailed description of the present invention with a preferred embodiment, and any simple modifications and changes made to the embodiment will not depart from the spirit and scope of the present invention.
