[0033] Refer to Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: a gynecological intrauterine sampler, including the rod body 1, the rod body 1 is convenient for doctor hand -held operation and is sent into the sampling brush 2 in the patient's uterine cavity and carries out sampling. The rod body 1 upper surface is provided with sampling brush 2, and the sampling brush 2 is in contact with the uterine cavity inner wall, rotates or scrapes and so on in the uterine cavity, and the main role of the sampling brush 2 is to gather the sample such as the liquid and the exfoliated cell in the uterine cavity, and the rod body 1 is provided with telescopic component inside, and the main role of telescopic component is to realize the telescopic function of sampling brush 2. Telescopic component includes push rod 4, and push rod 4 lateral wall sliding connection is in the rod body 1 inside, and push rod 4 can slide up and down along the rod body 1 inside under the action of push block 3, to drive sampling brush 2 realizes telescopic action. Push rod 4 one end is fixedly connected with push block 3, and doctor can transmit external force to push rod 4 by pushing push block 3, and then control the telescoping of sampling brush 2. Push rod 4 other end is fixedly connected with connecting rod 5, and connecting rod 5 plays the role of connecting push rod 4 and sampling brush 2, and connecting rod 5 one end is fixedly connected in sampling brush 2 lower surface, guarantees the close connection of sampling brush 2 and connecting rod 5, and the rod body 1 is provided with clamping groove 6 inside, and clamping groove 6 is used for cooperating with elastic block 8, and in the telescoping process of sampling brush 2, elastic block 8 can slide into or slide out clamping groove 6, to realize the fixing of the telescoping position of sampling brush 2, and push rod 4 is fixedly connected with mounting sleeve 7 inside, and the role of mounting sleeve 7 is to provide mounting position and support for elastic block 8, and mounting sleeve 7 is provided with elastic block 8 inside, and elastic block 8 lateral wall sliding connection is in clamping groove 6 inside, and elastic block 8 lateral wall sliding connection is in mounting sleeve 7 inside, so that elastic block 8 can accurately cooperate with clamping groove 6, realize the effective fixing and unlocking of the telescoping position of sampling brush 2, ensure the normal work of telescopic component and the stable telescoping of sampling brush 2, and the rod body 1 upper surface is fixedly connected with protective cover 9, and the main role of protective cover 9 is to protect sampling brush 2 when sampling brush 2 is stored in the rod body 1 inside, prevent external factors from causing pollution or damage to sampling brush 2, ensure the cleanness and integrity of sampling brush 2, so that the next time use can normally collect sample. Sampling brush 2 lateral wall sliding connection is in protective cover 9 inside, and such connecting mode makes sampling brush 2 can slide along the inner wall of protective cover 9 stably in the telescoping process, and connecting rod 5 lateral wall sliding connection is in the rod body 1 inside, and connecting rod 5 lateral wall sliding connection is in protective cover 9 inside.
[0034] In the use of the gynecological intrauterine sampling device for sampling work, the sampling brush 2 is the key component for directly contacting the uterine wall to obtain samples. Its design needs to consider both softness and sampling effectiveness. After being sent into the uterine cavity, it can gently contact the uterine wall and effectively collect cell samples from the uterine wall without damaging the uterine tissue. The push block 3 plays an important role in starting the operation. When the push block 3 is pushed, the human applied force can be transmitted to the push rod 4. The structure and position design of the push block 3 facilitates the doctor's operation and force, and its cooperation with the surrounding components is tight. Under the push of the push block 3, the push rod 4 can transmit the force to the position where the elastic block 8 is located, thereby driving the elastic block 8 and the sampling brush 2 connected thereto to move up and down, ensuring that the sampling brush 2 can accurately extend or retract from the protective cover 9. The elastic block 8 works with the clamping groove 6. In the initial state, the elastic block 8 is clamped in the lower clamping groove 6, which plays a positioning and limiting role for the sampling brush 2, preventing it from accidentally extending out of the protective cover 9 in a non-operating state. When subjected to the extrusion of the push rod 4, the elastic block 8 can smoothly slide out of the lower clamping groove 6 and move up due to its own elasticity. When the elastic block 8 slides to the position of the upper clamping groove 6, its own elasticity pushes the elastic block 8 to quickly and accurately clamp into the upper clamping groove 6 for fixation, thereby stably keeping the sampling brush 2 in the extended state for sampling operation. When the sampling brush 2 is not working, the protective cover 9 completely wraps it to prevent the sampling brush 2 from being contaminated by external impurities such as bacteria and secretions in the vagina. At the same time, after sampling is completed, when the sampling brush 2 reenters the protective cover 9, the protective cover 9 can prevent the uterine samples carried by the sampling brush 2 from being scraped off or contaminated during the removal process, ensuring the integrity and purity of the samples and providing reliable protection for subsequent detection work. The rod body 1 is the main supporting structure of the entire sampler, which has good rigidity and appropriate length and thickness. When the rod body 1 is rotated for sampling, it can uniformly transmit the rotational torque applied by the doctor to the sampling brush 2, so that the sampling brush 2 can perform a circular brushing action on the uterine wall to collect samples comprehensively. The length design can meet the needs of deep sampling into the uterine cavity, and the thickness design facilitates the doctor's holding operation. The material selection of the rod body 1 needs to meet the biocompatibility requirements of medical equipment to ensure safety in the uterine cavity.
[0035] Reference Figure 1 and Figure 3The anti-skid assembly comprises a sleeve 10 fixedly connected to the side wall of the rod body 1, which is made of silica gel and has good flexibility and elasticity, so as to closely fit the side wall of the rod body 1. The side wall of the rod body 1 is fixedly connected to convex points 11 in the shape of semicircle and arranged in a ring shape, and the side wall of the convex points 11 penetrates through the side wall of the sleeve 10. These convex points 11 can significantly increase the roughness of the surface of the rod body 1. The side wall of the rod body 1 is also fixedly connected to a handle 12, and the inside of the handle 12 is fixedly connected to an anti-skid pad 13 made of rubber, which has a high friction coefficient and can further enhance the friction between the hand and the rod body 1, so as to facilitate the doctor to hold the rod body 1. In addition, the inside of the push block 3 is provided with vertical lines 14, which can increase the friction of the surface of the push block 3. When the push block 3 is pushed, the doctor can better apply force and accurately control the pushing amplitude and speed of the push block 3, thereby indirectly accurately controlling the action of other components linked with the push block 3, and ensuring the stable performance of the whole sampler.
[0036] The sleeve 10 made of silica gel arranged on the outside of the rod body 1 plays a multi-faceted important role. The silica gel itself has excellent flexibility and elasticity, which can effectively buffer the pressure applied by the hand during holding, avoid hand discomfort or even fatigue caused by long-time holding or improper force, and greatly improve the comfort of holding. The semi-spherical convex points 11 on the sleeve 10 further optimize the anti-skid performance. These convex points 11 are evenly distributed on the surface of the sleeve 10, and the semi-spherical design increases the surface roughness while forming multiple-point contact with the skin of the fingers. When the hand has a slight tendency to slide, the convex points 11 can hinder the occurrence of sliding by virtue of the friction between them and the skin, so that the user can more accurately control the operation of the rod body 1. Whether it is the axial pushing and pulling action or the circumferential rotating action, the operation error caused by hand sliding can be effectively reduced. The handle 12 also plays a key role in finger positioning. Its position on the rod body 1 allows the doctor to quickly and naturally find the appropriate placement position when picking up the sampler, and the anti-skid pad 13 fixedly connected inside the handle 12 further enhances the anti-skid effect. The anti-skid pad 13 is made of rubber and can generate a large friction force when in contact with the hand, effectively preventing the hand from sliding axially during holding. This improves the accuracy and safety of the operation. The vertical lines 14 on the push block 3 increase the roughness of the surface of the push block 3. When the doctor's fingers contact the push block 3 and perform a pushing operation, the friction between the vertical lines 14 and the skin of the fingers allows the doctor to better apply force and control the pushing amplitude and speed of the push block 3. In the operation of accurately controlling the extension and retraction position of the sampling brush 2, this friction can avoid the position deviation of the sampling brush 2 caused by the slipping of the push block 3, ensuring that the sampling brush 2 can accurately extend or retract from the protective cover 9, thereby improving the accuracy and safety of the whole sampler operation, reducing the risk of injury to the patient caused by operation errors and the impact on the accuracy of the sampling result.
[0037] Working principle: when using the device for sampling work, first by sending the sampling brush 2 into the uterine cavity, then by pushing the push block 3, make it push the push rod 4, so that the elastic block 8 is extruded, with the push force of the push rod 4, let the elastic block 8 slide out of the lower card slot 6 and move up, when sliding to the position of the upper card slot 6, the elasticity of the elastic block 8 itself will push the elastic block 8 to slide and be fixed in the upper card slot 6, through the push of the push rod 4, the sampling brush 2 will also be pushed out of the protective cover 9, and contact with the uterine wall, and then rotate the rod body 1 to sample, when the sampling is completed, by pulling down the push block 3, the elastic block 8 is retracted and slides out of the upper card slot 6, until the elastic block 8 is reinserted into the lower card slot 6, at this time the sampling brush 2 will reenter the protective cover 9, at this time the rod body 1 can be pulled out, the sampling is completed, the rod sleeve 10 made of silica gel is arranged on the outer side of the rod body 1, and the semispherical convex point 11 is added, the silica gel sleeve can play a buffering role, make the holding more comfortable, at the same time its soft characteristics can better fit the hand, and the semispherical convex point 11 further increases the friction, the handle 12 can be used as the positioning mark of the fingers, at the same time, when holding, through the anti-skid pad 13 can effectively block the axial sliding of the hand, enhance the anti-skid effect, through the vertical line 14 can increase the friction of holding the push block 3, so as to improve the accuracy and safety of operation.
