As described in the background art, when a doctor operates a conventional endoscope, the doctor holds the operation part with the left hand to control the twisting direction, and holds the insertion part with the right hand to apply certain propelling force to the insertion part so as to propel the insertion part in a human body cavity. However, since the hardness adjusting mechanism is disposed at the end of the operation portion, when the hardness of the insertion tube needs to be adjusted, the hardness adjusting mechanism is not directly operated by the left hand and the right hand is required to be operated because the hardness adjusting mechanism is far away, thereby reducing the operation efficiency.

In order to solve the above problem, embodiments of the present application provide a hardness adjustment device and an endoscope, which can improve operation efficiency.

In a first aspect, an embodiment of the present application provides a hardness-softness adjusting device. For adjusting the hardness of the endoscope insertion tube, as shown in fig. 1, the hardness adjusting device 10 includes:

an operating member 110; when the hardness of the insertion tube needs to be adjusted by a doctor, the operating element 110 can be operated by fingers, in the embodiment of the application, the operating element 110 is a knob, and the hardness can be adjusted by rotating the knob by the fingers, and it can be understood that the knob can be a threaded knob, a pentagonal knob, and the like.

A transmission mechanism 120, one end of the transmission mechanism 120 is connected with the operation member 110;

the adjusting assembly 130, the adjusting assembly 130 is connected with the other end of the transmission mechanism 120;

the fixed seat 140, the adjusting component 130 is movably arranged on the fixed seat 140; and

an elastic member 150, one end of the elastic member 150 being fixed, the other end of the elastic member 150 being connected with the adjusting assembly 130;

when the operating element 110 rotates, the transmission mechanism 120 is driven to move, and the transmission mechanism 120 is used for converting the rotation of the operating element 110 into the reciprocating linear motion of the adjusting assembly 130, so that the elastic element 150 extends and retracts.

In the embodiment of the present application, the elastic member 150 is a spring tube, and an insertion tube (not shown) is sleeved on an outer side of the spring tube. The hardness of the insertion pipe can be adjusted by changing the extension and retraction of the spring pipe. Wherein, the spring tube contracts, the insertion tube hardens, the spring tube extends, and the insertion tube softens. It is understood that the elastic member 150 may also be an elastic membrane, an elastic bellows, or the like.

It can be understood that, when the hardness is adjusted, the fixing base 140 is fixed, and the adjusting assembly 130 makes a reciprocating linear motion on the fixing base 140. And, during adjustment, one end of the elastic element 150 is stationary relative to the fixing base 140, and the other end is connected to the adjusting assembly 130 and follows the adjusting assembly 130 to perform reciprocating linear motion.

It should be noted that the transmission mechanism 120 can be any transmission mechanism 120 capable of converting the rotational motion of the operation element 110 into the reciprocating linear motion of the adjustment assembly 130, and the present embodiment does not limit the type of the transmission mechanism 120, and in the present embodiment, the transmission mechanism 120 is a crank-link mechanism.

On one hand, the hardness adjusting device 10 can arrange the operating part 110 on the operating part of the endoscope, which is convenient for the doctor to operate; on the other hand, when the insertion tube is used, the doctor can adjust the telescopic state of the elastic element 150 only by rotating the operating element 110 with one finger, so that the purpose of adjusting the hardness of the insertion tube is achieved, and one hand of the doctor can adjust the bending state of the insertion tube and the hardness of the insertion tube. That is, when the operator holds the operation portion with one hand of the doctor, the operator 110 can be rotated with the fingers of the hand without the assistance of the other hand, that is, without stopping the operation of the other hand, thereby improving the operation efficiency.

In one embodiment, as shown with reference to fig. 1 and 2, the driving mechanism 120 includes a driving end 121, a driving end 122, and an output end 123. The driving end 121 is connected to the operating element 110, the output end 123 is connected to the adjusting component 130, and the driving end 122 is connected to the driving end 121 and the output end 123. When the operating element 110 is rotated, the operating element 110 drives the driving end 121 to rotate, and the driving end 121 drives the output end 123 to perform a reciprocating linear motion along the first direction through the driving end 122. In fig. 1, the a direction denotes a first direction, i.e., an axial direction of the spring tube.

In a specific operation process, the driving end 121 rotates along with the operating member 110, and the driving end 122 converts the rotation of the driving end 121 into the reciprocating linear motion of the output end 123, so that the adjusting assembly 130 performs the reciprocating linear motion in the first direction. By such an arrangement, the transmission mechanism 120 has the advantages of simple structure, high force transmission efficiency, convenience in operation and the like.

In one embodiment, as shown in fig. 2, the driving end 121 includes: a first rotary shaft 1211 and a rotary table 1212, one end of the first rotary shaft 1211 is fixedly connected to the operating element 110, and the other end of the first rotary shaft 1211 is connected to the rotary table 1212. Thus, the first rotary shaft 1211 can connect the transmission mechanism 120 with the operating element 110 on the one hand, and can transmit the rotary force of the operating element 110 to the rotary disk 1212 on the other hand, so that the rotary disk 1212 can rotate along with the operating element 110.

It is understood that, in an embodiment, the connection position of the first rotating shaft 1211 and the rotating disc 1212 may be located at the center of the rotating disc 1212, in which case, the first rotating shaft 1211 is fixedly connected to the rotating disc 1212, and the first rotating shaft 1211 rotates around its axis and drives the rotating disc 1212 to rotate around its center line. In another embodiment, the joint between the first shaft 1211 and the turntable 1212 may not be located at the center of the turntable 1212, in which case, the first shaft 1211 may be fixedly connected to the turntable 1212, or may be rotatably connected to the turntable 1212, and the first shaft 1211 rotates around the center line of the turntable 1212 and drives the turntable 1212 to rotate around its own center line.

The transmission end 122 comprises a second rotating shaft 1221 and a connecting rod 1222, one end of the second rotating shaft 1221 is rotatably connected with the turntable 1212, and the connection position of the second rotating shaft 1221 and the turntable 1212 is arranged eccentrically to the center of the turntable 1212; link 1222 includes oppositely disposed first and second ends 1222a, 1222b; the other end of the second rotating shaft 1221 is rotatably connected to the first end 1222a of the connecting rod 1222. Thus, the turntable 1212 rotates to drive the second rotating shaft 1221 to rotate around the center line of the turntable 1212, and the second rotating shaft 1221 drives the first end 1222a of the connecting rod 1222 to rotate around the center line of the turntable 1212, so that the second end 1222b of the connecting rod 1222 performs a reciprocating linear motion.

The output end 123 includes a third shaft 1231, one end of the third shaft 1231 is rotatably connected to the second end 1222b of the connecting rod 1222, and the other end of the third shaft 1231 is rotatably connected to the adjusting assembly 130. Thus, the second end 1222b of the connecting rod 1222 drives the adjusting component 130 to perform a reciprocating linear motion through the third rotating shaft 1231.

In one embodiment, referring to fig. 1, the adjusting assembly 130 includes an adjusting member 131, and the adjusting member 131 is rotatably connected to the output end 123, and in particular, the adjusting member 131 is rotatably connected to the third rotating shaft 1231. The fixing base 140 has a supporting surface 141, and the adjusting member 131 is located on the supporting surface 141. The supporting surface 141 is provided with a limiting component 143 for limiting the moving direction of the adjusting piece 131. It is understood that the adjusting member 131 can be slidably connected to the supporting surface 141, and the adjusting member 131 can be placed on the supporting surface 141 and can slide on the supporting surface 141.

Through setting up spacing subassembly 143, on the one hand can be injectd the direction of motion of regulating part 131 in the first direction, avoids the direction of motion of regulating part 131 to take place the deviation to influence the regulation effect of regulating part 130 to elastic component 150, on the other hand can inject the displacement distance of regulating part 131 in the first direction, makes regulating part 131 adjust elastic component 150 in predetermined movement range, prevents that regulating part 131 from moving excessively in the first direction.

Specifically, the limiting assembly 143 includes two first limiting members 1431, and the two first limiting members 1431 are respectively located on two opposite sides of the adjusting member 131 in the first direction. One of the two first limiting members 1431 abuts against one end of the adjusting member 131, and a gap is formed between the other one of the two first limiting members 1431 and the other end of the adjusting member 131; or, a gap is formed between one of the two first limiting members 1431 and one end of the adjusting member 131, and the other of the two first limiting members 1431 is abutted against the other end of the adjusting member 131; or, there is a gap between both ends of the adjusting member 131 and the two first limiting members 1431, that is: the adjusting member 131 is located between the two first limiting members 1431, and both ends of the adjusting member 131 are not in contact with the two first limiting members 1431.

In the embodiment of the present application, by providing one first limiting member 1431 on each of two opposite sides in the first direction, the moving range of the adjusting member 131 can be limited between the two first limiting members 1431, so that the adjusting member 131 adjusts the elastic member 150 within a predetermined moving range, on one hand, the adjusting member 131 is prevented from moving excessively in the first direction, and on the other hand, the adjusting member 131 is prevented from falling off the supporting surface 141.

In one embodiment, referring to fig. 1 and fig. 2, the limiting assembly 143 includes two second limiting members 1432, and the two second limiting members 1432 are respectively located on two opposite sides of the adjusting member 131 in the second direction. The second direction is perpendicular to the first direction and parallel to the plane of the supporting surface 141. Fig. 3 is a plan view of the softness adjuster 10 in fig. 1, and the direction b in fig. 3 is a second direction.

In the embodiment of the present application, by disposing one second limiting member 1432 on each of two opposite sides in the second direction, the moving direction of the adjusting member 131 can be limited in the first direction, so as to prevent the adjusting member 131 from moving in the second direction, and prevent the moving direction of the adjusting member 131 from deviating, thereby affecting the adjusting effect of the adjusting assembly 130 on the elastic member 150.

The shape of the adjusting member 131 is not limited in the embodiment of the present application. In the embodiment of the present application, the adjusting element 131 is shaped like an "i", a "waist" of the adjusting element 131 is clamped between the two second limiting elements 1432, and when the adjusting element 131 makes a reciprocating linear motion along the first direction, the "head" and the "tail" of the adjusting element 131 can also abut against the side edges of the second limiting elements 1432 in the first direction, so that the second limiting elements 1432 can also limit the adjusting element 131 in the first direction.

The connecting member 132 is disposed through the sliding slot 144, and one end of the connecting member 132 is connected to the adjusting member 131, and the other end is connected to the pushing ring 133. Thus, the adjusting member 131 drives the connecting member 132 to move, the connecting member 132 drives the pushing ring 133 to move, and the pushing ring 133 drives the elastic member 150 to extend and retract.

It can be understood that the camera module, the optical device, the surgical instrument, etc. can be inserted from the opening of the accommodating cavity 142 and extend out of the fixing portion 160 through the central tube 160, so as to facilitate the doctor to operate the endoscope for diagnosis and treatment.
