Description

Technical Field

[0001] This utility model relates to a cell brush handle, specifically a rotatable cell brush handle. Background Technology

[0002] Cell brushes are used in conjunction with endoscopes, entering the body's natural cavities through the endoscope's forceps channel. Under endoscopic observation, cells are brushed for pathological analysis. In existing cell brush handles, the drive mechanism, fixed to a metal cord, can only move along the handle, causing the cord and brush to move back and forth. It cannot rotate the brush. To rotate the brush, the entire handle must be rotated, causing the drive mechanism, cord, and brush to turn, which is inconvenient. Therefore, a rotatable cell brush handle is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a rotatable cell brush handle to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotatable cell brush handle, comprising a handle body; characterized in that it further comprises a rotatable driving component slidably mounted in the handle body and a fixing component disposed within the driving component for fixing one end of a metal rope; it further comprises a limiting component movably disposed on the handle body for limiting the circumferential angle of the driving component and a limiting guide groove disposed on the driving component corresponding to the limiting component.

[0005] Further preferably, it also includes a slot on the handle body that is adapted to the limiting member, the slot having limiting grooves on both sides, and the limiting member having a limiting block adapted to the slot.

[0006] A further preferred embodiment includes a shrinkage groove provided on the limiting member to facilitate the inward shrinkage of the limiting member.

[0007] A further preferred embodiment includes a rope hole on the fixing member that is adapted to the metal rope, and the fixing member is also provided with a compression groove that passes through the rope hole.

[0008] More preferably, the fixing member is threadedly installed at one end of the driving member.

[0009] A further preferred embodiment includes a wristband mounted on the other end of the drive unit.

[0010] The beneficial effects of this utility model are as follows: by movably installing the driving component inside the handle body, it can drive the fixing component and the metal rope to rotate, thereby driving the cell brush at the other end of the metal rope to rotate. At the same time, the driving frame can slide inside the handle body to drive the metal rope and the cell brush to move. By setting the limiting component and the limiting guide groove, the circumferential angle of the driving component can be limited during use, so that it can only move without rotating.

[0013] The following description, in conjunction with the accompanying drawings, further illustrates a rotatable cell brush handle according to this invention.

[0014] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] See Figures 1-4 As shown, a rotatable cell brush handle includes a handle body 1; characterized in that it further includes a drive member 2 that is slidably installed in the handle body 1 and is rotatable, and a fixing member 3 disposed in the drive member 2 for fixing one end of a metal rope 5; it also includes a limiting member 4 that is movably disposed on the handle body 1 for limiting the circumferential angle of the drive member 2, and a limiting guide groove 21 disposed on the drive member 2 corresponding to the limiting member 4. By movably installing the drive unit 2 inside the handle body 1, it can drive the fixing unit 3 and the metal rope 5 to rotate, thereby driving the cell brush at the other end of the metal rope 5 to rotate. At the same time, the drive frame can slide inside the handle body 1, thereby driving the metal rope 5 and the cell brush to move. By setting the limiting component 4 and the limiting guide groove 21, the circumferential angle of the driving component 2 can be limited during use, so that it can only move without rotating.

[0017] In one embodiment, the device further includes a slot 11 provided on the handle body 1 and adapted to the limiting member 4, wherein limiting grooves 12 are provided on both sides of the slot 11, and limiting blocks 41 adapted to the slot 11 are provided on the limiting member 4. The slot 11 is used to limit the installation of the limiting member 4, and the limiting slot 12 and the limiting block 41 are used to limit the position of the limiting member 4 within the slot 11.

[0018] In one embodiment, a shrinkage groove 42 is provided on the limiting member 4 to facilitate the inward retraction of the limiting member 4; by providing the shrinkage groove 42, the limiting member 4 can be easily retracted inward by pressing the limiting member 4, thereby facilitating the removal of the limiting block from the limiting groove 12.

[0019] In one embodiment, the fastener 3 is further provided with a rope hole 51 adapted to the metal rope 5, and the fastener 3 is also provided with a compression groove 52 that passes through the rope hole 51. The fixing member 3 is threadedly installed at one end of the driving member 2; With the setting of rope hole 51, one end of metal rope 5 is inserted into rope hole 51. With the setting of compression groove 52, when the fixing member 3 is installed on the driving member 2, it is tightened by screwing. During the tightening process, the fixing member 3 is squeezed inward, thereby compressing the fixing member 3 into compression groove 52, thereby pressing the metal rope 5. When the metal rope 5 is inserted into rope hole 51, the installation firmness of metal rope 5 can also be enhanced by adding glue. The connection end between the fixing component 3 and the driving component 2 can also be tapered.

[0020] In one embodiment, a wristband 6 is also included at the other end of the drive unit 2; the wristband 6 facilitates the operation of the drive unit 2.

[0021] When using this utility model: When only the cell brush needs to be moved, rotate the drive unit 2 to align the limiting guide groove 21 on the drive unit 2 with the position of the limiting member 4. Then, by pressing the limiting member 4 and pushing the limiting member 4 forward, the limiting block 41 on the limiting member 4 is dislodged from the limiting groove 12 and inserted into the limiting guide groove 21. After releasing the pressing of the limiting member 4, the limiting block 41 on the limiting member 4 is locked into another limiting groove 12 of the slot 11, thus completing the position limitation. At this time, the metal rope 5 and the cell brush can only be moved by pushing and pulling the drive unit 2. When it is necessary to move and rotate the cell brush, simply press the drive component 2 and pull it backward. When the limiting block 41 on the drive component 2 comes out of the limiting groove 12 and moves out of the limiting guide groove 21, move the limiting block 41 to another limiting groove 12 and then release the press of the limiting component 4, so that the limiting block 41 on the limiting component 4 can be locked into the limiting groove 12. At this time, the cell brush can be moved and rotated at the same time.

[0022] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
