The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 3, the present embodiment discloses a curet adapted to a digestive endoscope, that is, optionally equipped with the curet when the digestive endoscope is extended into the body for examination or treatment. The curet comprises a curet rod 1 and a curet head 2, wherein the curet head 2 is connected with one end of the curet rod 1, and the other end of the curet rod 1 can be connected with a forceps channel of a digestive endoscope. The curet head 2 comprises a curet head body 21 and saw teeth 22, wherein the saw teeth 22 are arranged at one end of the curet head body 21 far away from the curet rod 1, and when the digestive endoscope is used for treatment, a large amount of pus and inflammatory substances attached to the surface of the mucous membrane of the digestive tract are required to be removed, so that the attached foreign matters can be removed by the saw teeth 22. In addition, if there are many foreign matters such as the scraped-off pus during the treatment, the normal operation is affected by the foreign matters adhering to the curette head 2, so that the curette needs to be taken out of the forceps channel of the digestive endoscope for cleaning. In order to solve the problem, the curet provided in this embodiment is further provided with a hollow portion 210 on the curet head body 21, the hollow portion 210 penetrates through the curet head body 21 along the thickness direction of the curet head body 21, so that the foreign matters scraped by the saw teeth 22 will not be extruded on one side surface of the curet head body 21 close to the saw teeth 22, i.e. the foreign matters can pass through the hollow portion 210 on the curet head body 21 first and remain in the alimentary canal, and after waiting for the operation, the foreign matters are cleaned uniformly, so that the treatment efficiency can be improved, and the pain of the patient is relieved.

Preferably, as shown in fig. 3, a plurality of serrations 22 are provided, and a plurality of serrations 22 are provided at intervals on the head body 21. The number of the saw teeth 22 is increased, so that the foreign matter removing efficiency of the curet can be improved, and in the practical implementation, the number of the saw teeth 22 and the interval between the adjacent saw teeth 22 can be reasonably configured according to the volume of the curet head body 21 and the volume of the saw teeth 22.

Preferably, as shown in fig. 3, the saw teeth 22 have a tapered structure, and the tip of the saw teeth 22 is curved. The whole conical structure of the saw teeth 22 can ensure that the saw teeth 22 and the curet head body 21 have larger connection surfaces, ensure the connection strength of the saw teeth 22 and the curet head body 21, and simultaneously facilitate the removal of foreign matters, while the tooth tip shape of the saw teeth 22 is a curved surface, and the tooth tip is similar to a spherical structure, so that the tissue damage of the digestive tract mucous membrane can be avoided when the foreign matters are removed.

In addition, in the present embodiment, the curet head body 21 includes a first body 211 and a second body 212 connected, and the first body 211 and the second body 212 are disposed at a first included angle, the saw teeth 22 are disposed at one end of the first body 211 far away from the second body 212, and the curet rod 1 is connected to one end of the second body 212 far away from the first body 211. On this basis, even if the first body 211 and the second body 212 are both in a lamellar structure, when they are disposed at the first included angle, the curette rod 1 can be conveniently located at the center of the digestive tract, so that the saw teeth 22 are as close to the mucosal surface of the digestive tract as possible. When the saw teeth 22 need to be adjusted to scrape other positions, the curette rod 1 can be rotated first to match with the movement of the endoscope body of the digestive endoscope so as to meet the requirements, and the up-and-down movement of the curette rod 1 is omitted so as to enable the curette rod 1 to move close to or away from the mucous membrane surface of the digestive tract, thereby reducing the position adjustment amplitude of the curette and reducing the operation complexity.

Further, the second body 212 is disposed at a second angle β with respect to the curette rod 1, and 20 ° < β < 60 °. When the curette rod 1 is placed against the mucosal surface of the digestive tract, the curette head body 21 can still keep a gap with the mucosal surface of the digestive tract, which facilitates the scraped foreign matters to pass through the hollowed-out portion 210 and leak to the side of the curette head body 21 facing away from the saw teeth 22. So as to avoid the contact between the curet head body 21 and the mucous membrane surface of the digestive tract, so that the foreign matters can not leak from the side of the curet head body 21 close to the saw teeth 22 to the side of the curet head body 21 far from the saw teeth 22, thereby affecting the treatment efficiency.

On the basis that the second body 212 and the curet rod 1 are arranged at a second included angle beta, the first body 211 and the saw teeth 22 on the first body incline towards one side of the second body 212, so that a doctor can observe the positions of the saw teeth 22 under the digestive endoscope conveniently, and the operation angle can be adjusted in time. Preferably, the first angle formed by the first body 211 and the second body 212 is alpha, 70 degrees < alpha < 100 degrees. In this embodiment, the first angle formed by the first body 211 and the second body 212 is a right angle.

Still further, referring to fig. 2, the second body 212 includes a main body 2121 and a connection 2122 connected thereto, and the connection 2122 is connected to the key lever 1 and gradually reduces in width toward the key lever 1. Wherein main part 2121 is used for guaranteeing the striking off area that curet head 2 had to guarantee to strike off efficiency, and connecting portion 2122 sets up to trapezium structure, and it is connected with main part 2121 and curet pole 1 respectively, then can realize curet from curet head 2 to curet pole 1's gentle transition, both can guarantee joint strength, avoids appearing sharp corner simultaneously. Preferably, the long side of the trapezoid is equal in length to the main body 2121, and the short side of the trapezoid is flush with the end of the curette rod 1, i.e., perpendicular to the extending direction of the curette rod 1, the cross-sectional area of the curette rod 1 is small so that it extends into the jaw channel of the digestive endoscope to be fixed. In this embodiment, the curette rod 1 has a cylindrical shape, and its diameter can be determined according to practical requirements.

Alternatively, the hollowed-out portion 210 may be disposed on both the first body 211 and the second body 212, so that the foreign objects may pass through the curette head body 21 from various angles. Or because the curet is used under the digestive endoscope, that is, the volume of the curet is smaller, if the strength of the curet is ensured, the hollowed-out portion 210 can be only arranged on the second body 212. Preferably, the curet can be made of metal materials meeting medical standards so as to ensure the strength of the curet.

Optionally, each corner of the curet head body 21 is provided with an arc chamfer to avoid accidentally injuring the mucosa of the digestive tract at the tip end on the curet when the curet is operated, i.e. the angle is adjusted or the curet is rotated.

The above embodiments merely illustrate the basic principle and features of the present utility model, and the present utility model is not limited to the above embodiments, but may be varied and altered without departing from the spirit and scope of the present utility model. The scope of the utility model is defined by the appended claims and equivalents thereof.
