[0016] The following will make a detailed description of the present utility model in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following:

[0017] As Figures 1-3 shown, a bump collection rod, the main body is a collection rod, and an annular breaking groove 13 is also provided in the middle of the collection rod;

[0018] A front collection head 11 is provided at the front end of the collection rod, and a number of bumps are provided on the front collection head 11. The present utility model is provided with a front collection head with a special bump structure, and the bumps can better collect gastric mucosa tissue and improve the collection rate.

[0019] The bumps are divided into several bump groups, and the bumps in each bump group are annularly arrayed with the center of the cross-section perpendicular to the central axis of the front collection head 11 as the center of the circle, forming a bump ring; several bump rings are arranged at intervals from front to back. The grouped and spaced bumps make the structure of the front collection head more regular and can collect gastric mucosa tissue more evenly.

[0020] The bumps between adjacent bump groups are staggered. The staggered distribution can further improve the contact between the bumps and the gastric mucosa tissue and further improve the collection rate.

[0021] The bumps are divided into several long bumps and several short bumps.

[0022] Several long bumps are divided into several long bump groups, and the bumps in each long bump group are annularly arrayed with the center of the cross-section perpendicular to the central axis of the front collection head 11 as the center of the circle, forming a long bump ring 111;

[0023] Several short bumps are divided into several short bump groups, and the bumps in each short bump group are annularly arrayed with the center of the cross-section perpendicular to the central axis of the front collection head 11 as the center of the circle, forming a short bump ring 112; the long bump ring 111 and the short bump ring 112 are alternately distributed from front to back. The design of different lengths of bumps can adapt to the uneven and uneven structure of the collection position, thereby improving the collection rate of the collection rod at these positions and enabling the present utility model to effectively collect at such positions where it is difficult to collect gastric mucosa tissue. Thus, the situation of needing to re-collect due to a low collection rate can be prevented.

[0024] The bumps of adjacent long bump groups and short bump groups are distributed in a staggered manner. The design of the staggered distribution can further improve the contact between bump groups of different lengths and the gastric mucosa tissue, and further improve the collection rate.

[0025] For the long bumps and short bumps of the present utility model, the length and shortness are defined according to the perpendicular distance from the end of the bump to the central axis of the collection rod. The perpendicular distance from the end of the long bump to the central axis of the collection rod is greater than the perpendicular distance from the end of the short bump to the central axis of the collection rod.

[0026] A flocked collection head 12 is further provided at the rear end of the collection rod. The present utility model is provided with a bilateral collection structure, that is, a front collection head with bumps at the front end and a flocked collection head at the rear end, which improves the structural utilization rate of the collection rod and thus reduces the structural cost. And the break groove is used to break the collection rod into two parts, which is convenient for the doctor to separate the front collection head and the flocked collection head through the break groove and put them into different fixing solution bottles for sealing after sampling.

[0027] The material of the collection rod is ABS resin. The ABS resin material has high strength, good impact resistance, thermal stability and chemical stability, and good processing performance.

[0028] Further, the length of the collection rod is preferably 75 mm.

[0029] Further, the break groove 13 is provided on the side close to the front collection head, and the length from the front collection head 11 to the break groove 13 is preferably 30 mm, that is, the break length of the front collection head is preferably 30 mm; the distance from the flocked collection head 12 to the break groove 13 is preferably 45 mm, that is, the break length on the side of the flocked collection head is preferably 45 mm.

[0030] Anti-slip lines 14 for increasing friction are further provided on the collection rod. The anti-slip lines 14 are provided at the position of the lower part of the collection rod close to the flocked collection head 12. The anti-slip lines can improve the friction force when the doctor holds the collection rod, prevent slipping, and thus reduce the influence on the operation.

[0031] Usage method: If only the front collection head needs to be used for collection, after collecting the tissue with the front collection head, break the collection rod into two parts through the break groove, and then seal the front collection head part into the fixing solution bottle; if only the flocked collection head needs to be used for collection, after collecting the tissue with the flocked collection head, break the collection rod into two parts through the break groove, and then seal the flocked collection head part into the fixing solution bottle; if both the flocked collection head and the front collection head need to be used, after collecting the tissue respectively by the above method, seal them into different fixing solution bottles.

[0032] Although the present utility model uses specific embodiments and their alternative ways to illustrate and explain the present utility model, it should be understood that various changes and modifications can be implemented as long as they do not deviate from the spirit of the present utility model. Therefore, it should be understood that the present utility model is not limited in any sense except by the accompanying claims and their equivalent conditions.
