Description

Technical Field

[0001] The utility model relates to human daily necessities, in particular to medical instruments, in particular to a minimally invasive surgical instrument lumen sampling rod. Background Art

[0002] There is an increasing demand for minimally invasive surgery or minimally invasive examinations in hospitals. For example, the number of minimally invasive surgeries performed with flexible endoscopes is increasing, and the number of reuses required is increasing. Minimally invasive surgical instruments need to be reused, cleaned, sterilized and disinfected in a timely, efficient and safe manner. The inner cavity of the reused instrument before and after cleaning, disinfection and sterilization needs to be inspected using a sampling rod to detect the effect of cleaning, disinfection and sterilization. In addition, the lumens of surgical and inspection instruments entering the patient's body are becoming thinner and thinner, with diameters reaching the millimeter level and lengths of more than 1 meter, such as some flexible endoscope biopsy tubes and suction tubes. In the prior art, the sampling hair of the sampling rod is coarse and the overall diameter is relatively large, which is inconvenient and inefficient, and it is also easy to damage the inner wall of the expensive minimally invasive surgical instrument. Summary of the invention

[0015] The present invention is further described below in conjunction with an embodiment, but the present invention is not limited to the embodiment. Any similar structure and similar changes of the present invention should be included in the protection scope of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of clear description and is not a limitation on the technical solution of the present invention.

[0016] like Figure 1-Figure 2 As shown, the utility model is a minimally invasive surgical instrument lumen sampling rod, comprising a rod body segment 3 and a neck body segment 2 fixed to one end of the rod body segment 3, the neck body segment 2 is provided with a hair body portion 1 at one end away from the rod body segment 3, the hair body portion 1 is provided with sampling villi with a thickness between 0.8 and 25D, the diameter of the neck body segment 2 is between 0.8 and 1.5 mm, the diameter of the hair body portion 1 is between 1.0 and 4.0 mm, and the diameter of the rod body segment 3 is between 1.0 and 2.4 mm.

[0017] In the textile and fiber industry, "D" is the abbreviation of Denier, which is a common unit of fiber thickness and is used to indicate the weight per 9000 meters of fiber.

[0018] Furthermore, the length of the rod section 3 is between 100 and 2000 mm.

[0019] Furthermore, the length of the neck section 2 is between 10 and 50 mm. The length of the neck section 2 plus the length of the rod section 3 can detect a slender cavity with a diameter of the endoscope reaching the millimeter level and a length of more than 1 meter.

[0020] Furthermore, the length of the hair body 1 is between 5 and 20 mm. The inner core of the hair body 1 is an extension of the neck section 2, and the diameter of the inner core is the same as the diameter of the neck section 2.

[0021] Furthermore, the sampling hair is made of polyethylene hair, and the sampling hair is fixed on the hair body 1 by an electrostatic flocking process. The sampling hair can pick up pollutants in the lumen of the minimally invasive surgical instrument, thereby facilitating the detection of pollutants.

[0022] Furthermore, the neck section 2 is made of polypropylene material. Specifically, polypropylene (PP for short) material has the characteristics of wear resistance, water resistance and corrosion resistance, thereby avoiding damage during use.

[0023] Furthermore, the rod section 3 is made of thermoplastic material.

[0024] Furthermore, the rod segment 3 is a hollow tube, and the neck segment 2 extends into the rod segment 3. The neck segment 2 is connected to the rod segment 3 by inserting the neck segment 2 into the rod segment 3, heating it at the injection temperature required by the thermoplastic material, and then quickly using a bite forceps to bite and compress it into shape after it is softened by heating, so that the rod segment 3 and the neck segment 2 become one, and the hair body 1 and the neck segment 2 are prevented from being separated from the rod segment 3, so that when the sampling motion is performed back and forth in the tube cavity, sufficient force can be transmitted to ensure that the required sample is collected.

[0025] Specifically, the sampling fluff, polyethylene fleece, polypropylene, thermoplastic materials, etc. in this embodiment all adopt well-known solutions in the prior art, which are well understood by those skilled in the art and will not be described in detail here.

[0026] Working principle of this embodiment: When using the sampling stick, the sampling stick can be directly inserted into the lumen of the minimally invasive surgical instrument, so that the sampling villi of the hair body part 1 can directly obtain the sample of the lumen pollutants to be detected. It can also be directly inserted into the detection cavity after saturating the liquid reagent for adsorption and reaction with the pollutants. After taking it out, the degree of contamination of the pollutants can be directly judged qualitatively or quantitatively according to the results of the reactions based on different principles. The lumen of the instruments used for surgery and inspection is thin and long. The diameter of this sampling stick reaches the millimeter level and the length is more than 1 meter. For example, for some soft endoscope biopsy pipes, suction pipes, etc., the sampling stick of the utility model has thin hair body and small diameter. It is easy to insert and efficient, and it is not easy to damage and wear the inner wall of the minimally invasive surgical instrument. The detection sampling stick of the utility model provides a basic guarantee for the quality detection of cleaning and disinfection, and effectively avoids the occurrence of nosocomial infections caused by minimally invasive surgery.

[0027] The sampling rod hair body 1 has sampling villi with a diameter of millimeters, which can detect the microscopic lumens of surgical instruments, especially the slender lumens with a diameter of millimeters and a length of more than 1 meter in the endoscope, such as some soft endoscope biopsy pipes, suction pipes, etc., solving the technical problems of the sampling hair body of the sampling rod for sampling the inner cavity of surgical instruments in the prior art being thick, the overall diameter being too large, and the inner wall of the expensive minimally invasive surgical instruments being easily damaged. In addition to not being easy to wear the lumen, the utility model can efficiently sample on the basis of appropriate cost, ensure the quality of cleaning, disinfection and detection, and provide a guarantee for effectively avoiding nosocomial infections caused by minimally invasive surgery.
