As will be described later, since the harvesting rod holder portion 29b is capable of axial rotation and longitudinal linear motion as part of the lead screw 29, the harvesting rod 37 is capable of axial rotation and longitudinal linear motion.

The spiral cutter portion 37c is a portion made of a blade 37e extending in a spiral direction like a coil spring, and enters the inside of the tissue when the collecting rod 37 is rotated in the forward direction.

The spiral cutter portion 37c is accommodated inside the tube body 36a in the initial state, and each time the operation button 34 is pressed after pressing the forward switch 28b, a certain length is moved forward of the tip blade portion 36b. Each, for example, advances by 3 mm. Also, when the reverse switch is pressed, all the advanced parts move backward. In some cases, it may be designed to move backward by a predetermined length when pressing the operation button 34 after pressing the reverse switch 28a.

On the other hand, the casing 21 is composed of two casing pieces 21a and a tip cap 21b. The casing piece 21a and the tip tab 21b provide an inner space 21f in a mutually coupled state. The casing 21 itself takes the form of a pistol. However, the shape of the casing 21 can be changed as many as necessary. A plurality of lamp holes 21e are formed on both side casing pieces 21a. The lamp hole 21e is a hole that opens the number-of-times display lamp portion 27 to be described later.

In the casing 21, the driving unit, the operation means, the battery 23, the charging terminal 24, the operation button 34, the motor operation substrate 35, the control circuit board 25, the switch unit 28, the number of times displayed The lamp unit 27 is provided.

The driving unit includes a motor 26, a torque transmission link 41, a lead screw 29, and a nut block 39. The motor 26 outputs rotational force by the electric power applied from the battery 23. The operation of the motor 26 is performed by the operation button 34. That is, it is operated when the operation button 34 is pressed.

The operation button 34 is elastically supported in the outer direction of the casing 21 by the action of the spring 34b, and serves to connect the circuit of the motor operating substrate 35 when pressed by the user. The power of the battery 23 is transferred to the motor 26 as the circuit is connected.

The torque transmission link 41 is a connecting member connecting the drive shaft 26a of the motor 26 and the lead screw 29, and transmits the rotational force of the motor 26 to the lead screw 29 and at the same time leads screws ( 29) is allowed to move in the longitudinal direction, that is, in the direction of the arrow c or vice versa.

The lead screw 29 is a mechanical element in which malea acid is formed on the outer circumferential surface, like a general lead screw, and is provided between the collecting rod 37 and the motor 26.

At the leading end of the lead screw 29, a collecting rod holder portion 29b is integrally formed. The collecting rod holder portion 29b is a portion for receiving and fixing the connector 37b described above and has a stopper portion 29c on its outer circumferential surface. The fixing method of the connector 37b to the collecting rod holder portion 29b can be variously implemented. The stopper portion 29c is a ring-shaped protrusion integrally formed on the outer circumferential surface of the collecting rod holder portion 29b, and blocks the moving projection 32a, which will be described later, in the direction of the arrow g shown in FIG. 6A.

In addition, a driven shaft portion 29a is located at the rear end portion of the lead screw 29. The driven shaft portion 29a is a square rod or a hexagonal rod and is slidable in an arrow c direction or the opposite direction while being fitted in the torque transmission link 41. Since the driven shaft portion 29a is a hexagonal rod or a square rod, the rotational force of the motor is transmitted to the lead screw 29 as it is.

The nut block 39 engages with the lead screw 29 in a fixed state inside the casing 21, and when the motor 26 is operated, the lead screw 29 rotates axially and linearly moves in the longitudinal direction. To do. Since the nut block 39 is fixed, the lead screw 29 is axially rotated by receiving the rotational force of the motor and linearly moving in the direction of the arrow c or vice versa.

The above-described driving unit can be variously changed as much as possible within the limits of axial rotation and linear motion of the collecting rod. For example, it is possible to apply a different rotational force generating means in place of the motor for the axis rotation of the collecting rod, or to apply a linear motion actuator of various structures for the longitudinal linear motion of the collecting rod.

On the other hand, the operation means is to move the push plate 32 in the direction of the arrow k in Figure 5a. In other words, in a state in which the spiral cutter portion 37c is advanced and exposed in front of the tip blade portion 36b, the outer tube is pushed in the same direction to accommodate the exposed spiral cutter portion 37c in the tube body 36a. It is to act. At this time, the tissue cut on the blade 37e of the spiral cutter portion 37c is cut by the tip blade portion 36b and collected in the tube body 36a as described above.

The tip of the push plate 32 is a pushing tip 32c, and when the trigger 31 is pulled in the direction of the arrow m, the push tab portion 36h is pushed forward to move it.

In addition, a locking protrusion 32a is protruded on the upper surface of the mill plate 32. The locking protrusion 32a is a part that is caught by the stopper portion 29c formed in the collecting rod holder portion 29b. Since the locking projections 32a are blocked by the stopper portion 29c, the locking projections 32a do not go forward than the stopper portion 29c.

The return spring 33 is located on the bottom surface of the mill plate 32 and elastically supports the mill plate 32 to the rear. By the action of the return spring (33), the rear end of the push plate (32) always comes into contact with the upper pressing part (31b) of the trigger (31).

The trigger 31 is supported so as to be rotatable to the casing 21 through the rotating shaft 31a, and has a pulling portion 31c and a pressing portion 31b. The pulling portion 31c extends to the outside of the casing 21 and takes a curved shape like a trigger of a pistol, and the pressing portion 31b is located on the opposite side of the pulling portion about the rotating shaft 31a, and the pulling portion When (31c) is pulled in the direction of the arrow m, it is a part that pushes and moves the mill plate (32). Reference numeral 21g is a rotation limiting projection that limits the rotation angle of the pressing portion 31b.

The operation means having the above-described structure can also be variously changed according to the design of the product to achieve the same purpose. That is, as long as the outer tube can be moved back and forth in the longitudinal direction, the structure can be implemented differently. For example, instead of a trigger and a spring, a two-way motor can be applied, or a slider of a different operation type can be applied.

The switch part 28 is disposed on the upper side of the casing 21 while being connected to the control circuit board 25. The switch section 28 includes a reverse switch 28a, a forward switch 28b, a power switch 28c, and a display lamp 28d.

In addition, when not being charged, the display lamp 28d is turned on in the on state of the power switch 28c, and off in the off state.

The switch unit 28 can also implement any number of different positions or structures depending on the design of the product. For example, by designing the switch in the form of a dial, for example, when the dial switch is rotated to one side, it is the same as pressing the forward switch 28b, and when it is rotated in the opposite direction, the same effect as pressing the reverse switch 28a can be exhibited. Furthermore, a structure in which the motor is turned on and off can be applied by pressing or pulling the dial switch.

On the side of the motor 26, a number display lamp unit 27 is disposed. The number display lamp unit 27 includes a plurality of LED lamps that display the number of times the forward switch 28b is pressed. The operator can know the total entry distance of the spiral cutter part 37c through the number of the illuminated LED lamps, so that a safer operation is possible.

The battery 23 is a rechargeable battery and is connected to the charging terminal 24. When the battery 23 is discharged, a charging cable may be connected to the charging terminal 24 to charge the battery 23.
