Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an endoscope slag removal device and a use method thereof, and an endoscope system. Background Art

[0002] In modern medical technology, endoscope equipment is an important diagnostic and therapeutic tool, widely used in the examination and treatment of digestive system diseases. Endoscope equipment can enter the human body through natural cavities (such as the mouth and anus), directly observe the internal conditions of the digestive tract, and perform necessary biopsies, treatments, and other operations. However, in actual operations, the use of endoscope equipment may be affected by some factors, such as the patient's intestinal preparation.

[0003] In the prior art, for patients with inadequate intestinal preparation, methods such as cleansing enema or oral laxatives are usually used to clean the feces in the intestine to ensure the smooth progress of endoscopic examination. However, in actual operation, there are still situations such as poor bowel cleansing or difficulty in tolerating bowel cleansing agents during endoscopic examination, resulting in a large amount of fecal blocks, which obstructs the field of vision and seriously affects the inspection effect. In addition, for patients with acute intestinal bleeding, the presence of a large number of blood clots seriously affects the inspection effect and repeatedly blocks the endoscopic instrument channel, causing difficulty in operation and increasing the risk of perforation. Some doctors may use tools such as foreign body forceps, snares, and water flushing to try to remove solid residues such as fecal blocks and blood clots. However, these methods all have certain limitations. For example, feces are generally soft and easy to break, and foreign body forceps or snares cannot be clamped and removed. The method of removing fecal blocks using tools such as foreign body forceps may cause damage to the intestine and increase the patient's pain. Although water flushing can cause some feces to be sparse, the stool is still granular fecal residue, which cannot be sucked out by the endoscope.

[0034] Example 1

[0035] like Figures 1 to 6As shown, in an embodiment of the present invention, an endoscope slag removal instrument 100 includes an instrument end 110, a traction part 120, and a control end 130. The instrument end 110 and the traction part 120 can enter the body with the endoscope 200 through the instrument channel of the endoscope 200, and the control end 130 is arranged outside the instrument channel 210.

[0036] The instrument end 110 of the embodiment of the present invention includes an umbrella top 111, at least two first connecting rods 112, an umbrella surface 113, an umbrella handle 114 and at least two second connecting rods 115, wherein the number of the first connecting rods 112 and the second connecting rods 115 are the same.

[0037] The umbrella top 111 is formed with a first cavity 1111. As an example, the umbrella top 111 can be a cylindrical structure. The first cavity 1111 can be inserted and connected to the traction wire 121. The end of the umbrella top 111 is expandably connected to one end of the first connecting rod 112.

[0038] The first connecting rod 112 is a rod-shaped structure, which includes a rod body and two ends. One end of any first connecting rod 112 is expandably connected to the end of the umbrella top 111, and the other end is a free end.

[0039] The umbrella cover 113 can cover the umbrella top 111 and the first connecting rod 112 and enclose a slag storage space, and when the instrument end 110 is unfolded, the storage space can be used to store slag. In some preferred embodiments, the umbrella cover 113 is made of a soft silicone material to avoid damage to the body tissue.

[0040] The umbrella handle 114 is formed with a second cavity 1141. As an example, the umbrella handle 114 can be a cylindrical structure. The second cavity 1141 can be inserted and connected to the hose 122. The end of the umbrella handle 114 is expandably connected to the other end of the second connecting rod 115.

[0041] The second connecting rod 115 is a rod-shaped structure, which includes a rod body and two ends. One end of any second connecting rod 115 is expandably connected to the rod body of any first connecting rod 112, and the other end of any second connecting rod 115 is expandably connected to the end of the umbrella handle 114.

[0042] In some preferred embodiments, at least two first lugs 1112 are evenly arranged at the end of the umbrella top 111, and are expandably connected to the first connecting rod 112 through the first lugs 1112. At least two second lugs 1142 are evenly arranged at the end of the umbrella handle 114, and are expandably connected to the second connecting rod 115 through the second lugs 1142. The number of the first lugs 1112 and the second lugs 1142 is the same as that of the first connecting rod 112 and the second connecting rod 115. For example, if there are four first connecting rods 112, then there are four second connecting rods 115, first lugs 1112, and second lugs 1142. The first lug 1112 and the second lug 1142 are respectively provided with a first through hole 1113 and a second through hole 1143. The first connecting rod 112 is a solid rod, one end of which is provided with a first groove 1121, and a pair of first through holes 1122 are symmetrically provided on both sides of the first groove 1121. The first lug 1112 can be inserted into the first groove 1121 and connected by a first rivet penetrating the pair of first through holes 1122 and the first through hole 1113, so that the umbrella top 114 and the first connecting rod 112 can be connected in an expandable manner. The rod body of the first connecting rod 112 is provided with a third through hole 1123. The second connecting rod 115 is a rod with two ends open, one end of which is provided with a second groove 1151 with a larger opening, and the other end is provided with a third groove 1152 with a smaller opening, a pair of second through holes 1153 are symmetrically provided on both sides of the second groove 1151, and a pair of third through holes 1154 are symmetrically provided on both sides of the third groove 1152. The third through hole 1123 of the first connecting rod 112 is connected to the second through hole 1153 of the second connecting rod 115, that is, the rod body of the first connecting rod 115 can be inserted into the second groove 1151 and connected by the second rivet penetrating the first through hole 1123 and the pair of second through holes 1152, so that the second connecting rod 115 can be connected to the first connecting rod 112 in a deployable manner. The second lug 1142 can be inserted into the third groove 1152 and connected by the third rivet penetrating the pair of third through holes 1154 and the second through hole 1143. When the instrument end 100 is retracted, part of the rod body of the first connecting rod 112 is received in the second groove 1151 of the second connecting rod 115. With such a structural arrangement, the instrument end 100 can be in a smaller state after being received so that it can be received as a whole in the instrument channel of the endoscope 200.

[0043] The traction part 120 of the embodiment of the present invention includes a traction wire 121 and a hose 122, wherein the hose 122 can facilitate the traction part 120 to bend with the endoscope. One end of the traction wire 121 is connected to the first cavity 1111 of the umbrella top 111. As an example, it can be connected by welding after being inserted into the first cavity 1111. One end of the hose 122 is connected to the second cavity 1141 of the umbrella handle 114. As an example, one end of the hose 122 can be inserted into the second cavity 1141 of the umbrella handle 114 and connected by welding. The interior of the hose 122 extends to form a traction sliding cavity 1221, and the other end of the traction wire 121 extends along the traction sliding cavity 1221 and can move forward and backward therein.

[0044] In an embodiment of the present invention, the traction wire 121 is pushed forward, and the traction wire 121 pushes the umbrella top 111 connected thereto to move forward. The forward movement of the umbrella top 111 drives the first connecting rod 112 to move around the umbrella top 111 toward the umbrella handle 114, and then drives the second connecting rod 115 to move around the umbrella handle 114 toward the umbrella handle 114. After the other end (i.e., the free end) of the first connecting rod 122 enters the second groove 1251 of the second connecting rod 115, the entire instrument end 100 is finally contracted into a rectangular structure. The traction wire 121 is pulled backward, and the traction wire 121 drives the umbrella top 111 connected thereto to move backward. The backward movement of the umbrella top 111 drives the first connecting rod 122 to move around the umbrella top 111 in a direction away from the umbrella handle 114, and then drives the second connecting rod 115 to move around the umbrella handle 114 in a direction away from the umbrella handle 114. The other end (i.e., the free end) of the first connecting rod 122 is separated from the second groove 1151 of the second connecting rod 115, and the entire instrument end 100 is finally unfolded into an umbrella-shaped structure. Thus, by moving the traction wire 121 forward and backward, the entire instrument end can be contracted into a rectangular structure to facilitate insertion into the instrument channel of the endoscope and then enter the body, and after entering the body, it can be unfolded into an umbrella-shaped structure to be in a state of being able to store slag.

[0045] The hose 122 plays a supporting role. When a force is applied to the traction wire 121, the umbrella handle 114 can remain stationary, and only the umbrella top 111 is driven to move forward and backward relative to the umbrella handle 114. In some preferred embodiments, the hose 122 is a spring tube. This is because the spring tube is formed by tightly winding metal wires. The tightly wound metal wires bear the axial force, so that the axial compression resistance of the spring tube is strong, so that it will not be bent while maintaining flexibility.

[0046] like Figure 1As shown, the control end 130 of an embodiment of the present invention has one end of the control end 130 fixedly connected to the other end of the hose 122, and the other end of the traction wire 121 passes through the other end of the hose 122 and is movably connected to the other end of the control end 130. The control end 130 can control the movement of the traction wire 121 in the third sliding cavity 1221 to realize the expansion or contraction of the instrument end 110.

[0047] Specifically, the control end 130 includes a handle portion 131, a slider portion 132, and a hook portion 133. An operating sliding cavity 1311 is formed inside the handle portion 131. The slider portion 132 is sleeved on the outer periphery of the handle portion 131 and can move forward and backward. As an example, the slider portion 132 can be used for holding with the index finger and the middle finger. The other end of the hose 122 can be connected to one end of the handle portion 131. The other end of the traction wire 121 passes through the other end of the hose 122 and then enters the operating sliding cavity 1311 and is connected to the slider portion 132. The hook portion 133 is provided at the other end of the handle portion 131. As an example, the hook portion 133 can be used for holding with the thumb.

[0048] Example 2

[0049] like Figure 7 As shown, in an embodiment of the present invention, an endoscope slag removal instrument 100 includes an instrument end 110, a traction part 120, and a control end 130. The instrument end 110 and the traction part 120 can enter the body with the endoscope 200 through the instrument channel of the endoscope 200, and the control end 130 is arranged outside the instrument channel.

[0050] The difference between this embodiment and the first embodiment lies in the control end 130 , and the rest of the structure is the same as the first embodiment.

[0051] like Figure 8As shown, the control end 130 of the embodiment of the present invention includes a three-way valve body 131, a piston 132, a first water supply pipe 133 and a second water supply pipe 134. The interior of the three-way valve body 131 is formed with a first water chamber 1311 and a second water chamber 1312 that are connected. The diameter of the second water chamber 1312 is larger than the diameter of the first water chamber 1311. The diameter of the piston 132 is larger than the diameter of the first water chamber 1311. The piston 132 is placed in the second water chamber 1312 and can move back and forth in the second water chamber 1312 under the action of water pressure. The structural arrangement that the diameter of the second water chamber 1312 is larger than the diameter of the first water chamber 1311 forms a step between the second water chamber 1312 and the first water chamber 1311. The different settings of the diameters of the first water chamber 1311, the second water chamber 1312, and the piston 132 allow the piston 132 to move only in the second water chamber 1312 without entering the first water chamber 1311. This is to prevent the piston 132 from entering the bottom of the first water chamber 1311 and blocking the water inlet of the first water chamber 1311, thereby preventing it from returning to the second water chamber 1312.

[0052] The three-way valve body 131 includes an instrument connection end 1311, a first water supply connection end 1312, and a second water supply connection end 1313. The other end of the hose 122 can be connected to the instrument connection end 1311, and the traction wire 121 passes through the other end of the hose 122 and is connected to the piston 132. One end of the first water supply pipe 133 is connected to the first water supply connection end 1312, and the other end of the first water supply pipe 133 can receive water transmitted by an external water supply device. One end of the second water supply pipe 134 is connected to the second water supply connection end 1313, and the other end of the second water supply pipe 134 can receive water transmitted by an external water supply device.

[0053] In some preferred embodiments, the external water supply device can selectively transmit water to one of the first water supply pipe 133 or the second water supply pipe 134. As an example, when the external water supply device is connected to the first water supply pipe 133, the water can enter the first water chamber 1311 (or the second water chamber 1312) through the water inlet of the first water chamber 1311, and the piston 132 moves backward under the action of the water pressure, driving the traction wire 121 to pull backward, thereby expanding the instrument end 110. When the external water supply device is connected to the second water supply pipe 134, the water can enter the second water chamber 1312 (or the first water chamber 1311) through the water inlet of the second water chamber 1312, and the piston 132 moves forward under the action of the water pressure, driving the traction wire 121 to move forward, thereby contracting the instrument end 110.

[0054] In some preferred embodiments, Fig. 9As shown, the external water supply device is connected to the first water supply pipe 133 and the second water supply pipe 134 through the first overflow valve 310 and the second overflow valve 320, respectively. The first overflow valve 310 and the second overflow valve 320 can be opened under a specific water pressure to discharge the water in the first water supply pipe 133 or the second water supply pipe 134. In the preferred embodiment, the water supply pipe is continuously filled with water.

[0055] Example 3

[0056] According to another overall technical concept of the present invention, a method for using an endoscopic slag removal instrument is provided, which uses the endoscopic slag removal instrument 100 described in Examples 1 to 2 to perform slag removal, wherein: the control end 130 is operated to retract the instrument end 110 to enter the instrument channel 210 of the endoscope 200; the endoscope 200 is operated to enter the body, and the instrument end 110 enters the body with the endoscope 200; the control end 130 is operated to extend the instrument end 110 from the instrument channel 210; the control end 130 is operated to unfold the instrument end 110 to store the slag in the storage space; the endoscope 200 is operated to withdraw from the body, and the instrument end 110 withdraws from the body with the endoscope 200.

[0057] Example 4

[0058] According to another general technical concept of the present invention, an endoscope system includes an endoscope and the endoscope slag removal instrument described in Examples 1 to 2. An instrument channel 210 is provided inside the endoscope 200, and the instrument end 110 and the traction part 120 of the endoscope slag removal instrument 100 can pass through the instrument channel 210 and enter the body with the endoscope 200, and the control end 130 is arranged outside the instrument channel 210.

[0059] The endoscopic slag removal instrument of the embodiment of the present invention innovatively adopts an expandable or contractible umbrella-shaped instrument end structure, and the operating control end moves the traction part forward and backward. The forward and backward movement of the traction part drives the umbrella-shaped instrument end to expand or contract.
