[0002] With the development of medical technology, endoscope technology has emerged. Endoscopes are used to visually inspect hard-to-reach locations such as organs in the human body to observe pathological conditions. Usually, an endoscope includes a long insertion tube, a handle at the end of the insertion tube close to the operator, and a visual inspection device such as a built-in camera at the distal end of the long insertion tube. In order to be able to operate the endoscope inside the human body, the endoscope includes a bendable snake bone, and the direction of the tip of the snake bone end is adjusted by bending the snake bone, thereby changing the observation angle.

[0003] The endoscope connects the handle and the snake bone through two traction wires, so that the handle controls the snake bone to bend in four directions. The traction wires and the snake bone are connected by welding. In traditional technology, due to the high cost of endoscope equipment, it is disinfected and cleaned after use to achieve recycling. This method has the risk of cross infection due to incomplete disinfection, so disposable endoscopes have emerged, and the snake bone and other parts are made of plastic materials to achieve disposable use.

[0034] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 4An endoscope snake bone 100 includes: a connecting portion 110, the connecting portion 110 is used to connect with the front end; a winding portion 120, the winding portion 120 is connected to the connecting portion 110, the winding portion 120 is provided with an installation cavity 125, and the winding portion 120 is also provided with a first traction line hole 121, a second traction line hole 122, a third traction line hole 123 and a fourth traction line hole 124 arranged at intervals around the installation cavity 125, the installation cavity 125, the first traction line hole 121, the second traction line hole 122, the third traction line hole 123, and the fourth traction line hole 124 The four traction wire holes 124 are all arranged along the axial extension of the winding part 120, and the winding part 120 is provided with at least three wire passing holes, and at least three wire passing holes are arranged at intervals along the circumference of the winding part 120, and each wire passing hole is connected with the installation cavity 125 respectively; wherein, at least one wire passing hole is located between the first traction wire hole 121 and the second traction wire hole 122, at least one wire passing hole is located between the second traction wire hole 122 and the third traction wire hole 123, and at least one wire passing hole is located between the third traction wire hole 123 and the fourth traction wire hole 124.

[0035] During the winding process of the above-mentioned endoscope snake bone 100, a traction wire is passed from the bottom of the first traction wire hole 121 from bottom to top along the axial direction of the winding part 120, and then passes through the winding part 120 through the wire hole between the first traction wire hole 121 and the second traction wire hole 122, and then passes through the winding part 120 from the wire hole between the second traction wire hole 122 and the third traction wire hole 123, and finally passes from the top of the third traction wire hole 123 along the axial direction of the winding part 120 from top to bottom. Afterwards, another traction wire is passed from the bottom of the second traction wire hole 122 along the axial direction of the winding part 120 from bottom to top, and then passed through the wire hole between the second traction wire hole 122 and the third traction wire hole 123 to pass through the winding part 120, and then passed through the wire hole between the third traction wire hole 123 and the fourth traction wire hole 124 to enter the winding part 120, and finally passed from the top of the fourth traction wire hole 124 along the axial direction of the winding part 120 from top to bottom. The endoscope snake bone 100 can stably connect two traction wires through the combination of four traction wire holes and at least three wire holes, so that the four directions are effectively pulled, the winding is stable, not easy to slip, and the traction wire does not occupy the position in the installation cavity 125, and does not affect the installation of other components and the normal use of the endoscope snake bone 100.

[0036] In one embodiment, see Figure 1, there are at least six wire holes. The at least six wire holes include at least the first wire hole 126, the second wire hole 127, the third wire hole 128, the fourth wire hole 129, the fifth wire hole 130 and the sixth wire hole 131 which are arranged in sequence along the circumference of the winding portion 120. The first wire hole 126 and the second wire hole 127 are located between the first traction wire hole 121 and the second traction wire hole 122, the third wire hole 128 and the fourth wire hole 129 are located between the second traction wire hole 122 and the third traction wire hole 123, and the fifth wire hole 130 and the sixth wire hole 131 are located between the third traction wire hole 123 and the fourth traction wire hole 124. In this way, a new winding method is provided for the two traction wires: one traction wire passes through the first traction wire hole 121 from bottom to top, then passes through the winding part 120 from the first wire hole 126, passes through the winding part 120 through the second wire hole 127 to continue to run, then passes through the winding part 120 from the third wire hole 128, passes through the winding part 120 through the fourth wire hole 129, and passes through the third traction wire hole 123 from top to bottom, and is tightened to be wound and fixed. The other traction wire passes through the second traction wire hole 122 from bottom to top, then passes through the winding part 120 from the third wire hole 128, passes through the winding part 120 through the fourth wire hole 129 to continue to run, then passes through the winding part 120 from the fifth wire hole 130, passes through the winding part 120 through the sixth wire hole 131, and passes through the fourth traction wire hole 124 from top to bottom, and is tightened to be wound and fixed. After being tightened, the occupied space is further reduced, and the friction is increased to avoid slipping, thereby improving the use quality and reliability of the endoscope snake 100. This embodiment only provides a specific winding method, but is not limited thereto.

[0037] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The winding portion 120 is also provided with a first guide groove 132, which is provided on the outer wall of the winding portion 120, and the first wire hole 126 and the second wire hole 127 are connected to the first guide groove 132. Further, the winding portion 120 is also provided with a second guide groove 133, which is provided on the outer wall of the winding portion 120, and the third wire hole 128 and the fourth through hole are connected to the second guide groove 133. Further, the winding portion 120 is also provided with a third guide groove 134, which is provided on the outer wall of the winding portion 120, and the fifth wire hole 130 and the sixth through hole are connected to the third guide groove 134. In this way, the traction line can be hidden, the traction line is prevented from protruding, the flatness of the outer wall of the winding portion 120 is ensured, and the wear probability of the traction line is reduced.

[0038] In one embodiment, see Figure 2 Figure 3 and Figure 4The first guide groove 132 is extended along the circumference of the winding part 120, the second guide groove 133 is extended along the circumference of the winding part 120, and the third guide groove 134 is extended along the circumference of the winding part 120. In this way, during the winding process, the convenience of winding is improved through the guide grooves.

[0039] In one embodiment, see Figure 1 The winding portion 120 is further provided with a mounting platform 135, which is provided on the inner wall of the mounting cavity 125, and the first traction wire hole 121, the second traction wire hole 122, the third traction wire hole 123 and the fourth traction wire hole 124 are all provided on the mounting platform 135. In this way, the winding area can be limited to the mounting platform 135, without occupying the space of the mounting cavity 125, thereby avoiding affecting the installation and use of other components.

[0040] In one embodiment, see Figure 1 The mounting platform 135 includes a first mounting platform 1351, a second mounting platform 1352, a third mounting platform 1353 and a fourth mounting platform 1354 which are sequentially arranged along the circumference of the mounting cavity 125. The first mounting platform 1351 is provided with a first traction line hole 121, the second mounting platform 1352 is provided with a second traction line hole 122, the third mounting platform 1353 is provided with a third traction line hole 123, and the fourth mounting platform 1354 is provided with a fourth traction line hole 124. In this way, the first traction line hole 121, the second traction line hole 122, the third traction line hole 123 and the fourth traction line hole 124 are provided with opening positions respectively, and it is beneficial to improve the structural strength of the winding part 120.

[0041] In one embodiment, see Figure 1 The mounting platform 135 is provided with a limiting portion 136, which is used to prevent the traction line from entering the mounting cavity 125. In this way, the traction line can be limited to the mounting platform 135 by the limiting portion 136, without occupying the space of the mounting cavity 125, thereby avoiding affecting the installation and use of other components.

[0042] Specifically, see Figure 1The limiting portion 136 includes a first boss 1361 corresponding to the first traction line hole 121, a second boss 1362 corresponding to the second traction line hole 122, a third boss 1363 corresponding to the third traction line hole 123, and a fourth boss 1364 corresponding to the fourth traction line hole 124. The first traction line hole 121 is located between the first boss 1361 and the inner wall of the mounting cavity 125, the second traction line hole 122 is located between the second boss 1362 and the inner wall of the mounting cavity 125, the third traction line hole 123 is located between the third boss 1363 and the inner wall of the mounting cavity 125, and the fourth traction line hole 124 is located between the fourth boss 1364 and the inner wall of the mounting cavity 125. In this way, through the limiting action of the first boss 1361, the second boss 1362, the third boss 1363 and the fourth boss 1364, the traction line can be further limited on the mounting platform 135.

[0043] Optionally, the connection between the connecting portion 110 and the winding portion 120 may be plug-in, riveted, bonded, snap-fitted or other connection methods. Alternatively, the connecting portion 110 and the winding portion 120 are an integrally formed structure.

[0044] Specifically, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting portion 110 and the winding portion 120 are an integral injection molding structure. In this way, the structure is simple, the manufacturing is convenient, and the cost is low. At the same time, it is beneficial to improve the connection stability between the connecting portion 110 and the winding portion 120, thereby ensuring the structural stability of the endoscope snake bone 100. This embodiment only provides a specific connection method between a connecting portion 110 and a winding portion 120, but is not limited to this.

[0045] In one embodiment, an endoscope (not shown in the figure) includes the endoscope snake 100 in the above embodiment.

[0046] During the winding process of the above-mentioned endoscope, a traction wire is passed from the bottom of the first traction wire hole 121 from bottom to top along the axial direction of the winding part 120, and then passes through the winding part 120 through the wire hole between the first traction wire hole 121 and the second traction wire hole 122, and then passes through the winding part 120 from the wire hole between the second traction wire hole 122 and the third traction wire hole 123, and finally passes from the top of the third traction wire hole 123 along the axial direction of the winding part 120 from top to bottom. Afterwards, another traction wire is passed from the bottom of the second traction wire hole 122 along the axial direction of the winding part 120 from bottom to top, and then passed through the wire hole between the second traction wire hole 122 and the third traction wire hole 123 to pass through the winding part 120, and then passed through the wire hole between the third traction wire hole 123 and the fourth traction wire hole 124 to enter the winding part 120, and finally passed from the top of the fourth traction wire hole 124 along the axial direction of the winding part 120 from top to bottom. The endoscope snake bone 100 can stably connect two traction wires through the combination of four traction wire holes and at least three wire holes, so that the four directions are effectively pulled, the winding is stable, not easy to slip, and the traction wire does not occupy the position in the installation cavity 125, and does not affect the installation of other components and the normal use of the endoscope snake bone 100.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
