Technical Field

[0001] The utility model relates to the field of rotary cutting equipment, and particularly to a handle of a rotary cutting equipment. Background Art

[0002] Mammary gland diseases are common gynecological diseases. It is very important to make a clear diagnosis and treat the diseases in time. Especially for cancerous masses, if diagnosed and treated in time, the cure success rate is very high. At present, the most commonly used method for the diagnosis and treatment of mammary gland diseases is puncture.

Specific embodiments

[0024] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, terms such as "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] As Figures 1 to 5 shown, the handle of the rotary cutting device according to the embodiment of the present utility model mainly includes a housing 10, a driving mechanism 20, and an adjusting unit 30. The handle of the rotary cutting device may further include a locking hook 60 for fixing the rotary cutting needle.

[0027] The housing 10 can be made of medical polymer material or medical stainless steel, having the advantages of hygiene and antibacterial. A window 101 can be provided on the housing 10 to expose a part of the driving mechanism 20, facilitating the engagement of the driving mechanism 20 with the transmission mechanism of the rotary cutting needle (the rotary cutting needle is omitted from the drawing).

[0028] The driving mechanism 20 is located inside the housing 10 and is used to drive the transmission mechanism of the rotary cutting needle so that the inner cutting knife of the rotary cutting needle can translate in the axial direction and rotate in the circumferential direction.

[0029] The adjustment unit 30 is located on the surface of the housing 10 and is used to start / stop the drive mechanism 20, so that the inner needle knife translates relative to the outer needle tube of the rotary cutting needle in the axial direction by a specific distance, thereby adjusting the notch opening of the rotary cutting needle. The adjustment can be stepped adjustment or continuous adjustment.

[0030] It should be noted that a general rotary cutting needle includes an outer needle tube and an inner needle knife. The side wall of the outer needle tube is provided with a notch. The inner needle knife moves along the outer needle tube and can partially block the notch. The unblocked notch forms the sampling port of the rotary cutting needle. After the rotary cutting needle is inserted into the sampling position, the tissue sucked into the sampling port is cut off by the rotation of the inner needle knife as a sample. A part of the drive mechanism 20 is in contact with the transmission mechanism of the rotary cutting needle, driving the inner needle knife to translate, so the notch opening of the rotary cutting needle can be adjusted by adjusting a specific translation distance. Thus, a sample of the desired volume can be cut.

[0031] The adjustment unit 30 may include a first adjustment button 301 and a second adjustment button 302. The first adjustment button 301 is used to start / stop the forward rotation of the drive motor; and the second adjustment button 302 is used to start / stop the reverse rotation of the drive motor. This means that the increase or decrease of the notch opening of the rotary cutting needle can be adjusted.

[0032] The drive mechanism 20 specifically includes a drive motor and a drive gear set. The drive motor preferably adopts a stepper motor because the stroke of the drive motor is quantitatively controllable and it is easy to achieve stepped adjustment. The first end of the drive motor can be electrically connected to the adjustment unit 30. The second end of the drive motor is connected to the first end of the drive gear set, and the second end of the drive gear set is mechanically connected to the transmission mechanism of the rotary cutting needle.

[0033] In an embodiment of the present invention, the adjustment unit 30 is electrically connected to the main body of the rotary cutting device, and the main body of the rotary cutting device is electrically connected to the first end of the drive motor. Among them, the main body of the rotary cutting device sends a start / stop instruction to the drive motor according to the start / stop signal from the adjustment unit 30. In this embodiment, the handle of the rotary cutting device may further include a display unit 40, and the display unit 40 is electrically connected to the main body of the rotary cutting device, and the display unit 40 is used to display the notch opening of the rotary cutting needle.

[0034] In another embodiment of the present invention, the adjustment unit 30 is electrically connected to the controller of the handle of the rotary cutting device, and the controller is electrically connected to the first end of the drive motor. Among them, the controller sends a start / stop instruction to the drive motor according to the start / stop signal from the adjustment unit 30. In this embodiment, the handle of the rotary cutting device may further include a display unit 40, and the display unit 40 is electrically connected to the controller of the handle of the rotary cutting device, and the display unit 40 is used to display the notch opening of the rotary cutting needle.

[0035] To facilitate the operator holding the handle of the rotary cutting device to conveniently observe the adjustment of the notch opening while operating the button for adjustment, the adjustment unit 30 is arranged to be located on the first surface A of the housing 10, and the display unit 40 is arranged to be located on the second surface of the housing 10. This also avoids overcrowding of multiple components on the same surface of the housing.

[0036] The content displayed by the display unit 40 can be the notch opening of the rotary cutting needle represented in numerical form, such as 100%, 75%, 50%, 25%; it can also be the notch opening of the rotary cutting needle represented by a bar chart, where different lengths of bars correspond to different openings.

[0037] The handle of the rotary cutting device may further include a function unit 50 to implement different operating functions. The function unit 50 may specifically include a first function button 501 and a second function button 502. The first function button 501 is used to implement sample cutting, and the second function button 502 is used to implement vacuum suction.

[0038] For the handle of the rotary cutting device of the present utility model, by arranging the adjustment unit, the medical staff holding the handle of the rotary cutting device can directly adjust the notch opening of the rotary cutting needle without relying on others to be on duty and cooperate beside the main machine in the non-sterile area, and has the advantages of simple structure, convenient use, high working efficiency, etc.

[0039] The above specific embodiments do not constitute a limitation to the protection scope of the present utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
