Technical Field

[0001] The utility model relates to the technical field of cervical canal brush instruments, in particular to a cervical canal brush. Background Art

[0002] At present, in the gynecological endocervical canal scraping operation, there will inevitably be residual tissue left in the endocervical canal after conventional endocervical canal scraping, which will affect the accuracy of tissue pathology examination and thus affect clinical diagnosis. The reason for this is that the instruments and scraping sites of conventional endocervical canal scraping are relatively special, the scraping forceps are small, and the endocervical canal is a narrow, invisible tubular structure, which inevitably leads to the omission of some tissue in the endocervical canal.

[0017] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0018] In the technical solution of the utility model, a driving handle is set at the tail end of the cervical canal brush, and the servo motor is powered by a battery to pull the rotating shaft to rotate. The tube brush clamping assembly between the rotating shaft and the cervical canal brush is used to realize the transmission of the rotating force of the rotating shaft to the cervical canal brush, thereby playing the role of electric rotating tube brush sampling and achieving the effect of rotating sampling. After the conventional cervical canal scraping operation is completed, the cervical canal brush is placed into the cervical canal at a suitable depth. After the power is turned on, the cervical canal brush automatically rotates for sampling. After rotating for several weeks, all the residual tissues adhering to the cervical canal cavity and the cervical canal wall can be brushed off, and then the brush head can be placed in a specimen bottle and rinsed repeatedly, thereby ensuring the complete delivery of cervical canal tissues for inspection. Improve the accuracy of pathological examination.

[0019] Avoid the inability to completely remove the tissue remaining in the cervical canal after routine cervical curettage, which may lead to missed diagnosis. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] It includes a driving handle assembly 2 and a tube brush assembly 1 inserted into the end of the driving handle assembly 2; the tube brush assembly 1 includes a rear section pipe 11, a front section pipe 12 connected to the right end of the rear section pipe 11, and a brush head 13 arranged at the right end of the front section pipe 12.

[0033] The driving handle assembly 2 includes a hollow handle 21, a battery 24 loaded in the left section of the inner cavity of the hollow handle 21, and a servo motor 25 arranged in the right section of the inner cavity of the hollow handle 21, and the output shaft of the servo motor 25 is connected to a rotating shaft 26 penetrating the right side of the hollow handle 21 through a coupling, and a tube brush clamping assembly 27 is arranged at one end of the rotating shaft 26 located on the right side of the hollow handle 21; a battery compartment for placing the battery 24 is provided in the inner left section of the hollow handle 21, a motor compartment for installing the servo motor 25 is provided in the inner right section of the hollow handle 21, and a partition is provided between the battery compartment and the motor compartment, and a base for connecting and installing the servo motor 25 is fixed at the bottom of the motor compartment. A circular hole for the rotating shaft 26 to penetrate and rotate is provided on the right side of the inner side of the hollow handle 21, and a bearing matching the rotating shaft 26 is provided at the right end surface of the circular hole.

[0034] After the battery 24 is loaded into the left side of the inner cavity of the hollow handle 21, the power circuit and the conductive metal sheet in the inner cavity are used to transfer electricity to the servo motor 25, so that the servo motor 25 obtains electric energy, and at the same time, the control button on the outer surface of the hollow handle 21 is also connected to the control end of the servo motor 25 through the wire. After the button is pressed, the servo motor 25 starts to drive the rotating shaft 26 to rotate slowly and uniformly.

[0035] The tube brush clamping assembly 27 includes a fixed plate 271 , a tapered externally threaded tube 273 fixed on the right side surface of the fixed plate 271 , and an internally threaded sleeve 272 sleeved on the outer ring surface of the tapered externally threaded tube 273 .

[0036] Two notches 274 are provided on the right side port of the tapered externally threaded tube 273 for the tapered externally threaded tube 273 to deform inwardly. The tapered externally threaded tube 273 is shaped into a truncated cone, and the smaller end face of the tapered externally threaded tube 273 is connected to the right side of the fixed disk 271 .

[0037] The inner cavity side wall of the internal threaded sleeve 272 is provided with thread teeth, and the outer ring surface of the tapered external threaded tube 273 is provided with threads that are compatible with the inner cavity thread teeth of the internal threaded sleeve 272.

[0038] A break is provided at the connection between the rear tube 11 and the front tube 12, so that the front tube 12 and the brush head 13 can be cut off and dropped from the right end of the rear tube 11. In order to avoid missed diagnosis when collecting specimens after scraping, the tube brush is divided into two sections, and the rear tube 11 and the front tube 12 are separated through the break, and the front tube 12 and the brush head 13 are placed in the sample test tube together, so as to prevent the tissues that inevitably remain in the cervical canal after scraping from being sent for examination, resulting in a false negative rate.

[0039] A button for controlling the rotation of the servo motor 25 is installed on the outer side wall of the hollow handle 21 , and an LED screen for displaying the number of rotations of the servo motor 25 is also inlaid and installed on the outer side wall of the hollow handle 21 .

[0040] The left port of the hollow handle 21 is provided with a thread, and the left port of the hollow handle 21 is connected with a sealing end cap 22, and a section of the sealing end cap 22 located in the inner cavity of the hollow handle 21 is connected with an external thread ring 23, and the outer ring surface of the external thread ring 23 is adapted to the thread of the left port of the hollow handle 21. The left end of the rear section pipe 11 is inserted into the right port of the tapered external threaded tube 273, and a rubber pad is bonded to the inner cavity side wall of the tapered external threaded tube 273 by glue.

[0041] When connecting the new tube brush to the rotating shaft 26 to obtain rotational force, the left end of the rear section tube fitting 11 is inserted into the right side port of the tapered externally threaded tube 273, and the externally threaded ring 23 on the outer ring of the tapered externally threaded tube 273 is slowly screwed, so that the externally threaded ring 23 squeezes the right section of the tapered externally threaded tube 273, and the right section of the tapered externally threaded tube 273 gradually deforms inwardly by relying on the notch 274. At the same time, the tapered externally threaded tube 273 also tightly clamps the end of the rear section tube fitting 11, so that the output force of the rotating shaft 26 can be transmitted to the tube fitting.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
