Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a surgical electrode control mechanism and a surgical electrode forceps. Background Art

[0002] The existing surgical electrode holding structure is usually a scissor-type holding structure. In order to achieve the first direction reciprocating linear motion of the rod core 94, such as Figure 1 As shown, a first finger ring portion 91 is usually extended from the housing 90, and a second finger ring portion 92 is hinged to the housing 90 at a hinge shaft 93. The connecting end of the second finger ring portion 92 is clamped with the rod core 94. During operation, by holding the first finger ring portion 91 and the second finger ring portion 92, the second finger ring portion 92 is rotated relative to the housing 90 with the hinge shaft 93 as the rotation center, so as to drive the rod core 94 to move axially back and forth linearly. However, during operation, since the connecting end of the second finger ring portion 92 swings in an arc trajectory with the hinge shaft 93 as the rotation center, the combined tolerance between the connecting end of the second finger ring portion 92 and the rod core 94 is large, and the precision of the entire transmission structure is low.

[0052] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0053] Combine the following Figures 2 to 6 , describing an embodiment of the utility model.

[0054] According to an embodiment of the present utility model, on the one hand, a surgical electrode manipulation mechanism is provided, comprising:

[0055] The handle body 10 has an inner wall enclosing a mounting cavity 100;

[0056] The rod body 20 has one end in the first direction movably disposed in the mounting cavity 100;

[0057] The sliding member 30 is slidably disposed in the installation cavity 100 along the first direction. The sliding member 30 is engaged with one end of the rod body 20 in the first direction. The sliding member 30 is suitable for driving the rod body 20 to reciprocate along the first direction.

[0058] The connecting rod 40 is rotatably disposed at one end of the sliding member 30 away from the rod body 20 along the first direction;

[0059] The trigger body 50 has one end rotatably connected to the handle body 10 and the other end hinged to the end of the connecting rod 40 away from the sliding member 30. The trigger body 50 is suitable for driving the sliding member 30 to move reciprocatingly in a first direction relative to the handle body 10 through the connecting rod 40.

[0060] It should be noted that if Figure 1 As shown, in the scissors-type surgical electrode holding structure in the related art, during operation, since the connecting end of the second finger ring portion 92 makes a swinging motion in a circular arc trajectory with the hinge shaft 93 as the rotation center, not only does it lead to a large combined tolerance between the connecting end of the second finger ring portion 92 and the rod core 94, but also a low precision of the entire transmission structure; and during the transmission process, the rod core 94 not only needs to bear the pulling force and / or thrust along its own axial direction, but also needs to bear the bending stress, which places a high requirement on the rod diameter of the rod core 94.

[0061] Compared with the scissor-type surgical electrode holding structure in the related art, the surgical electrode manipulation mechanism provided by the utility model is provided with a sliding member 30. The sliding member 30 can slide back and forth linearly along a first direction in the installation cavity 100 of the handle body 10. The movement direction of the sliding member 30 is completely consistent with the movement of the rod body 20, and both are strict and synchronous linear motions. This not only greatly reduces the combined tolerance and transmission gap between the rod body 20 and the sliding member 30, and improves the fineness of the entire transmission structure, but also can reduce the rod diameter requirement of the rod body 20, which is conducive to meeting the miniaturization requirements of the electrode rod of the surgical electrode.

[0062] The surgical electrode manipulation mechanism provided by the utility model mainly includes a handle body 10, a rod body 20, a sliding member 30, a connecting rod 40 and a trigger body 50. The sliding member 30 is slidably arranged in the mounting cavity 100 of the handle body 10 along a first direction, so that the rod body 20 is driven to reciprocate along the first direction by the sliding member 30; the connecting rod 40 is arranged between the sliding member 30 and the trigger body 50, so that the swinging motion of the trigger body 50 is converted into a strict reciprocating linear motion of the sliding member 30 along the first direction, thereby greatly reducing the combined tolerance and transmission clearance between the rod body 20 and the sliding member 30, and improving the precision of the entire transmission structure.

[0066] Furthermore, during the manufacturing process, the inner wall of the handle body 10 can limit the first pin 61 and the second pin 62 at both ends in the second direction, thereby preventing the first pin 61 and the second pin 62 from being separated from the first limiting groove 102 .

[0067] In this embodiment, a first pin shaft 61 is provided to rotationally connect the sliding member 30 and the connecting rod 40 through the first pin shaft 61, so that the sliding member 30 makes a strict reciprocating linear motion driven by the connecting rod 40; a second pin shaft 62 is provided, and the second pin shaft 62 and the first pin shaft 61 are both slidably provided in the first limiting groove 102 to limit the sliding member 30, so that the sliding member 30 only makes a reciprocating linear motion along the first direction, thereby ensuring the consistency of the movement of the sliding member 30 and the rod body 20, which not only greatly reduces the combined tolerance and transmission clearance between the rod body 20 and the sliding member 30, but also improves the precision of the entire transmission structure.

[0068] In some embodiments, please combine Figure 3 and Figure 4 As shown, a first clamping portion 21 is provided at one end of the rod body 20 close to the sliding member 30 along the first direction;

[0069] Two second clamping portions 31 are disposed at one end of the sliding member 30 close to the rod body 20 along the first direction. The two second clamping portions 31 are spaced apart along the second direction and are suitable for clamping with the first clamping portion 21 .

During the manufacturing process, the first clamping portion 21 is clamped between the two second clamping portions 31 to axially fix the rod body 20 and the sliding member 30, so that the sliding member 30 drives the rod body 20 to perform reciprocating linear motion along the first direction, which is not only convenient for assembly, but also helps to ensure the consistency of the movement of the sliding member 30 and the rod body 20.

[0072] In some embodiments, see Figure 4 As shown, the first clamping portion 21 includes a plurality of first bosses 211, and the plurality of first bosses 211 are arranged on the rod body 20 along the first direction at intervals and form a plurality of first grooves 212;

[0076] In this embodiment, a spring 70 is provided so that one end of the spring 70 in the first direction abuts against the sliding member 30, and the other end abuts against the handle body 10, thereby compensating and / or offsetting the transmission clearance of the entire transmission structure to the greatest extent. This is not only beneficial to improving the fineness of the entire transmission structure and ensuring the stability of the entire transmission structure, but also beneficial to optimizing the control feel of the entire surgical electrode control mechanism.

[0077] In some embodiments, please combine Figure 3 and Figure 5 As shown, a plurality of second ribs 103 are further provided on the inner wall of the handle body 10 .
